PRELIMINARY – SUBJECT TO COMPLETION – DATED ~~SEPTEMBER 30,~~NOVEMBER 18, 2016

Middlefield Banc Corp. (“Middlefield”) and Liberty Bank, N.A. (“Liberty”) entered into an Agreement and Plan of Reorganization on July 28, 2016. We refer to the agreement as the Reorganization Agreement. A copy is attached to this joint proxy statement/prospectus as Annex A. The Reorganization Agreement provides that Liberty will merge into The Middlefield Banking Company, which is Middlefield’s bank subsidiary. The merger is subject to a number of conditions, including but not limited to obtaining approval of Middlefield stockholders and approval of Liberty ~~stockholders, and approval of state and federal bank regulatory agencies.~~stockholders.

Approximately 45% of the Liberty shares of common stock exchanged in the merger will be exchanged for Middlefield common stock, and the remaining Liberty shares of common stock exchanged in the merger (approximately 55%) will be exchanged for cash. Each share of Liberty common stock not owned by Middlefield will be converted at the effective time of the merger into the right to receive either: (x) $37.96 in cash or (y) 1.1934 shares of Middlefield common stock, subject to allocation procedures to ensure that approximately 45% of the outstanding shares of Liberty common stock are converted into Middlefield common stock and the remaining Liberty common stock is converted into cash. Excluding the 23,218 Liberty shares owned by Middlefield, which will be cancelled in the merger without consideration, the aggregate consideration payable to Liberty stockholders is approximately ~~$19.1~~$20.8 million in cash and approximately ~~515,164~~557,079 shares of Middlefield common stock. On July 27, 2016, the day before execution of the Reorganization Agreement, the per share closing price of Middlefield common stock on the Nasdaq Capital Market was $33.74. At that price the stock portion of the merger consideration would have a value of approximately ~~$17.4~~$18.8 million, and combined with the approximately ~~$19.1~~$20.8 million cash payable for 55% of Liberty common stock, the total merger consideration would be ~~$36.5~~$39.6 million, before the special dividend discussed below. Because the 1.1934 exchange ratio is fixed, the value of the ~~45%~~ stock portion of the total merger consideration will fluctuate with changes in the price of Middlefield stock. Holders of Liberty stock options and phantom shares also will receive ~~$1,147,516 in~~ cash for cancellation of those interests. Finally, in addition to the cash and stock merger consideration, Liberty stockholders will receive a special dividend of approximately $3.0 million in the aggregate, or $3.13 per share, before merger closing. Middlefield will receive no merger consideration for its 23,218 Liberty shares but it will be entitled to a proportionate share of the special dividend payment. See “SUMMARY– What Liberty stockholders will receive in the Merger.”

Middlefield will not issue fractional shares. A holder of Liberty common stock who would otherwise be entitled to a fractional share will instead receive cash, without interest, equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

Middlefield and Liberty will each hold a meeting of stockholders to vote on adoption and approval of the Reorganization Agreement. The meeting of Middlefield’s stockholders will be held at: 10:00 a.m. local time on ~~, 2016~~January 10, 2017 at ,Middlefield, Ohio. The meeting of Liberty’s stockholders will be held at: ~~10:~~9:00 a.m. local time on ,December 22, 2016 at ,Corporate College East, 4400 Richmond Road, Warrensville Heights, Ohio. At these meetings stockholders will be asked to approve and adopt the Reorganization Agreement and the merger transaction. Stockholders will also be asked to approve adjournment of the meeting, if adjournment is necessary to allow Middlefield ~~and~~or Liberty time to solicit additional proxies in favor of the Reorganization Agreement and the merger transaction. Liberty’s stockholder meeting is an annual meeting, so Liberty stockholders will also be asked to act upon routine annual meeting proposals, including election of directors and ratification of the appointment of independent auditors.

This document is a proxy statement of both Middlefield and Liberty. It is also a prospectus for Middlefield’s issuance of common stock in the merger. This joint proxy statement/prospectus describes Middlefield’s special meeting, Liberty’s annual meeting, and the merger proposal.

You should read the joint proxy statement/prospectus, including its annexes, carefully. The enclosed proxy voting materials allow you to vote your company’s common stock without attending the meeting.

On July 27, 2016, which was the day before public announcement of the proposed Merger, the closing price of Middlefield common stock on the Nasdaq Capital Market was $33.74. Based on that price for the stock portion of the Merger consideration and $37.96 per share for the cash portion, a Liberty stockholder who receives stock for 45% of his or her common stock at the 1.1934 fixed exchange ratio and cash for 55% would receive total Merger consideration with an implied value of approximately $39.00 per share, in addition to a special dividend of approximately $3.13 per share in cash. As of the more recent , 2016 date, the closing price for Middlefield common stock was $ . At that price and giving effect to the 1.1934 fixed exchange ratio, the implied value of a share of Liberty common stock exchanged for Middlefield common stock is $ . At this more recent price for Middlefield common stock, a Liberty stockholder who receives stock for 45% of his or her shares and cash for 55% would receive total Merger consideration with an implied value of approximately $ per share.

Middlefield will not issue fractional shares. Instead, a holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all shares of Liberty common stock owned by the holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

It is not part of the Merger consideration, but the Reorganization Agreement also provides that Liberty will declare a special dividend to stockholders before the Merger closes (or becomes effective). The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will receive no Merger consideration for its 23,218 Liberty shares but will be entitled to a proportionate share of the special dividend payment.

It is unlikely that Liberty stockholders as a group will elect to receive precisely 55% of the Merger consideration in cash and the remainder in Middlefield common stock. For that reason the Reorganization Agreement contains procedures to be followed if Liberty stockholders in the aggregate elect to receive more or less of the Middlefield common stock than Middlefield has agreed to issue –

You might not receive the amount of cash or stock you elect. As a result of the allocation procedures and other limitations outlined in this document and in the Reorganization Agreement, you may receive Middlefield common stock or cash in amounts that vary from the amounts you elect to receive.

Q:	How do Liberty stockholders make their election to receive cash, Middlefield common stock, or a combination of both?

If you own Liberty shares in “street name” through a bank, broker, or other nominee and you wish to make an election, you should seek instructions from the bank, broker, or other nominee holding your shares concerning how to make an election. If you do not send in the election form with your stock certificate(s) by the election deadline, you will be treated as though you made no election.

If a Liberty stockholder submits a valid election form and subsequently transfers any or all of the shares as to which an election has been made, that election will continue to apply to those shares in the hands of the transferee unless that election is changed or revoked in a timely fashion in the manner described below.

income from the special dividend could be subject to an additional tax on “net investment income,” depending on the individual’s adjusted gross income, as described below under “–“THE MERGER – Material U.S. Federal Income Tax Consequences – Medicare Tax on Net

Investment ~~Income~~Income..” You should consult with your tax advisor for the specific tax consequences of the Merger and the special dividend to you. See “THE MERGER – Material U.S. Federal Income Tax Consequences” on page .73.

The consequences of the Merger to each Liberty stockholder depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine the tax consequences of the Merger to you.

Liberty stockholders will be asked to (1) adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, (2) approve adjournment of the annual meeting to allow additional time for proxy solicitation if there are not sufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, (3) elect twelve directors for the term expiring at the earlier of (i) completion of the Merger or (ii) the 2017 annual meeting ~~upon the election of~~and until their successors ~~or,~~are elected and qualified, (4) ratify the selection of independent auditors, and (5) vote on any other business properly presented.

Middlefield’s board of directors believes that the Merger and other transactions under the Reorganization Agreement are in the best interests of Middlefield and its stockholders and recommends that Middlefield stockholders vote FOR the proposal to approve the transactions under the Reorganization Agreement, FOR the proposal to issue Middlefield common stock in the Merger, and FOR the proposal to adjourn the special meeting to solicit additional proxies if there are insufficient votes to approve the Reorganization Agreement transactions.

Liberty’s board of directors also determined that the Reorganization Agreement is in the best interests of Liberty and its stockholders and recommends that Liberty stockholders vote FOR the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and FOR the proposal to adjourn the annual meeting to solicit additional proxies if there are insufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. Regarding the other proposals to be presented at the annual meeting, Liberty’s board of directors recommends that stockholders vote FOR election of the identified director nominees and FOR ratification of the selection of the independent auditor.

Q:	Is my vote needed to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and to approve the other proposals?

Similar to the approval standard applicable to the Liberty stockholder meeting, approval of the transactions under the Reorganization Agreement by Middlefield stockholders requires the affirmative vote of the holders of at least two-thirds of the shares of Middlefield common stock outstanding. If there are insufficient votes to approve the Reorganization Agreement transactions when Middlefield’s stockholder meeting is held, the meeting may be adjourned to allow solicitation of additional proxies. The affirmative vote of the holders of a majority of the votes cast is necessary to approve adjournment. To approve issuance of Middlefield common stock in the Merger, the affirmative vote of a majority of the votes cast is necessary. Middlefield directors did not enter into agreements regarding voting of their shares of Middlefield common stock. Collectively they own approximately 102,153 shares, or approximately 4.6% of Middlefield’s outstanding common stock, with the right to acquire 20,674 additional shares.

If you hold Middlefield or Liberty common stock beneficially through a broker, bank, or other nominee, please see the discussion below regarding shares held in “street name.”

ratification proposal. Failure to return your proxy card or vote in person will have no effect on the adjournment proposal, the proposal to elect directors, or the proposal to ratify the auditor selection.

If you are a Middlefield stockholder and you do not return a proxy card or vote in person at the Middlefield special meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to approve the transactions under the Reorganization Agreement, this will have the same effect as a vote “AGAINST” that proposal, but failing to vote or abstaining will have no effect on the adjournment proposal or the proposal to approve issuance of shares.

If you are a Middlefield stockholder and you sign, date, and return a proxy card without giving voting instructions, your shares will be voted “FOR” approval of the transactions under the Reorganization Agreement and “FOR” approval of the share issuance, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment.

Under applicable Financial Industry Regulatory Authority (“FINRA”) and stock exchange rules, ~~of the Nasdaq Stock Market (“Nasdaq”),~~ brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals ~~Nasdaq considers~~stock exchanges consider “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Except for the auditor ratification proposal to be acted on at the Liberty stockholder meeting, Middlefield and Liberty believe the

stockholder meetings are “non-routine” and that brokers therefore will not be able to vote without specific voting instructions. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.

If you hold shares in “street name” and gave voting instructions to the broker, bank, or nominee, you must follow the broker, bank or nominee’s directions for changing your vote.

Q:	Are there risks that I should consider in deciding whether to vote in favor of the Reorganization Agreement and the other proposals?

Middlefield is a one-bank holding company. Middlefield’s principal subsidiary is The Middlefield Banking Company, an Ohio-chartered, nonmember commercial bank. Middlefield’s other subsidiary, EMORECO Inc., is an asset resolution corporation dedicated to the resolution and disposition of troubled assets of a central-Ohio bank that Middlefield acquired in 2007, specifically nonperforming loans and other real estate owned (“OREO”) held by the acquired bank as the result of borrower defaults on real estate-secured loans. That bank, Emerald Bank, operated as a separate subsidiary of Middlefield from 2007 through 2013, merging into The Middlefield Banking Company on January 20, 2014. At the end of ~~June~~September 2016 The Middlefield Banking Company had total assets of ~~$758.5~~$760.6 million and more than 140 employees.

The Middlefield Banking Company offers a broad range of banking services, including online banking and bill payment services for individuals and online cash management services for business customers at www.middlefieldbank.com. The Middlefield Banking Company’s customers are small and medium-sized businesses, professionals, small business owners, and retail customers. Loan products include operational and working capital loans, loans to finance capital purchases, term business loans, residential construction loans, selected guaranteed or subsidized loan programs for small businesses, professional loans, residential and mortgage loans, and consumer installment loans to purchase automobiles or boats, make home improvements, and for other personal expenditures. The bank makes available customary deposit-related products and services, such as checking, savings, negotiable order of withdrawal accounts, money market accounts, time certificates of deposit, safe deposit facilities, and travelers’ checks.

The Middlefield Banking Company operates in two distinct and very competitive markets, one in the northeastern Ohio counties of Geauga, Portage, Trumbull, Ashtabula, and Lake. The other market is central Ohio, specifically the Columbus area and Franklin County, the result of the 2007 acquisition of Emerald Bank. Ohio has a high concentration of financial service firms, many of which are significantly larger institutions with greater financial resources. Savings banks, savings and loan associations, commercial banks, mortgage banking companies, credit unions, insurance companies and other financial service companies compete to make loans. Savings and loan associations, savings banks, commercial banks, and credit unions compete for deposits, but non-depository entities such as mutual funds, securities and brokerage firms, and insurance companies also compete for depositors’ funds.

Liberty Bank, N.A.

25201 Chagrin Boulevard, Suite 120

Beachwood, Ohio 44122

Phone: (216) 359-5500

Liberty is a national bank established in October 1990. Liberty currently has approximately 40 employees. Liberty’s three bank offices are in Twinsburg in northern Summit County and Beachwood and Solon in eastern Cuyahoga County, Ohio. Liberty common stock is not listed on an exchange or traded over the counter. From inception, Liberty has been associated with the Akron and Cleveland business community and has sought to be a community banking resource for individuals and small business customers seeking the personalized service and local decision-making that distinguish community banks from the much larger regional and national banking institutions dominating the banking markets in Akron and Cleveland.

After the Merger, The Middlefield Banking Company will conduct through Liberty’s three bank offices the typical community banking business The Middlefield Banking Company has conducted through its offices since 1901. Both banks are community banks, and although Liberty serves the credit and deposit needs not only of local small businesses but also individuals, Liberty’s identity, its physical branch presence, and its marketing focus are more characteristic of a small business bank. The Middlefield Banking Company actively seeks to serve the lending and deposits needs not only of business customers but also individuals, for example individuals seeking home mortgage credit who do not have a preexisting commercial borrowing or deposit relationship with The Middlefield Banking Company. Middlefield believes the Merger will have the consequence of Liberty’s office locations being occupied by a community bank with a broader customer focus, with more active consumer marketing of The Middlefield Banking Company’s products and services in its new market in Cuyahoga County and Summit County.

The Reorganization Agreement (page )78)

If all of the Reorganization Agreement conditions are satisfied or waived, Liberty will merge into The Middlefield Banking Company, with The Middlefield Banking Company surviving. The Reorganization Agreement is Annex A to this joint proxy statement/prospectus and forms part of this joint proxy statement/prospectus.We encourage you to read the Reorganization Agreement carefully. It is the principal legal document governing the Merger. Immediately before Liberty merges into The Middlefield Banking Company, an interim bank subsidiary organized by Middlefield will merge into Liberty, with Liberty surviving momentarily before Liberty immediately thereafter merges into The Middlefield Banking Company.

What Liberty stockholders will receive in the Merger (page )79)

Liberty stockholders will be entitled to receive from Middlefield a combination of cash and Middlefield common stock when the Merger is completed, in addition to a special dividend of approximately $3.13 per share in cash immediately prior to the completion of the Merger. Subject to allocation procedures in the Reorganization Agreement ensuring that approximately 45% of the outstanding Liberty common stock is converted into Middlefield common stock and the remaining outstanding Liberty common stock is converted into cash, at the effective time of the Merger Liberty common stock not owned by Middlefield will be converted into the right to receive either:

$37.96 in cash, or

1.1934 shares of Middlefield common stock

Liberty stockholders will own up to approximately ~~18.7%~~20% of the Middlefield common stock outstanding after the Merger. Middlefield will not issue fractional shares. Instead, a holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all Liberty common stock owned by the holder at the effective time of the Merger) will receive cash, without interest, equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

It technically is not part of the Merger consideration, but pursuant to the Reorganization Agreement, Liberty must declare a special dividend to stockholders before Merger closing. The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will not receive Merger consideration for its 23,218 Liberty shares but will be entitled to a proportionate share of the special dividend payment.

What holders of Liberty stock options and phantom shares will receive (page )79)

Liberty’s compensation arrangements for officers and employees include equity-based awards, including stock options and phantom awards. There are option awards outstanding for ~~89,561~~13,572 shares, all of which are vested, including options held by Liberty’s ~~CEO, CFO, and~~ Chief Credit Officer to acquire a total of ~~79,989~~4,000 shares. At the effective time of the Merger each outstanding and unexercised option to purchase Liberty common stock will be cancelled in exchange for a cash payment equal to (x) the positive difference between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise. There are also outstanding 2,000 phantom share awards made in 2013.

Opinion of Middlefield’s Financial Advisor (page )63)

Material U.S. federal income tax consequences (page )73)

The U.S. federal income tax consequences of the Merger to a Liberty stockholder will depend on the relative mix of cash and Middlefield common stock received by such Liberty stockholder. Liberty stockholders should not recognize any gain or loss for U.S. federal income tax purposes if they exchange their Liberty shares solely for shares of Middlefield common stock in the Merger, except with respect to cash received in lieu of fractional shares of Middlefield common stock. Liberty stockholders will recognize gain or loss if they exchange their Liberty shares solely for cash in the Merger. Liberty stockholders will recognize gain, but not loss, if they exchange their Liberty shares for a combination of Middlefield common stock and cash, but their taxable gain in that case will not exceed the cash they receive in the Merger.The tax consequences of the Merger to each Liberty stockholder will depend on such Liberty stockholder’s own situation. Liberty stockholders should consult with their own tax advisors for a full understanding of the tax consequences of the Merger to them. Tucker Ellis LLP has delivered a tax opinion, dated September 26, 2016, to the effect that the Merger qualifies as a “reorganization” under Section 368(a) of the Internal Revenue Code. In addition, the completion of

the Merger is conditioned on receipt of a tax opinion from Tucker Ellis LLP, dated the closing date, to the same effect as the opinion described in the preceding sentence. The opinion will not bind the Internal Revenue Service, which could take a different view.

See “THE MERGER – Material U.S. Federal Income Tax Consequences” for a more detailed discussion of the tax consequences of the Merger.

Interests of directors and certain executive officers of Liberty (page )72)

Directors and certain executive officers of Liberty have employment and other compensation agreements or economic interests that give them interests in the Merger that are somewhat different from or in addition to their interests as Liberty stockholders. These interests and agreements include:

two members of the Liberty board of directors will be appointed to Middlefield’s board of directors. These directors are Chairman, President, and CEO William A. Valerian and Director Thomas W. Bevan,

•

all outstanding stock options issued by Liberty to officers and employees will be cancelled in exchange for cash equal to (x) the positive difference between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise; of the ~~$1,147,516~~$161,931 total payable in cancellation of options and phantom stock, ~~$1,025,704~~$62,986 will be paid to ~~President and CEO William A. Valerian, Chief Operating Officer and Chief Financial Officer Richard C. Ebner, and~~ Senior Vice President and Chief Credit Officer Craig E. Reay. Mr. Valerian’s son holds 1,000 phantom shares, which will be cancelled in exchange for $15,200 in cash,

Liberty’s CEO William A. Valerian and CFO Richard C. Ebner have employment agreements with Liberty. The employment agreements provide that they are entitled to a payment equal to 2.5 times salary when a change in control occurs, payable in equal installments over 30 months, plus payments for the cost of life insurance, long-term disability, and medical benefits over those 30 months. The Merger will constitute a change in control under those employment agreements. Mr. Valerian’s total payments are estimated to be ~~$904,611~~$929,502 and Mr. Ebner’s are estimated to be ~~$697,317,~~$716,900,

certain Liberty officers will receive retention bonuses to remain with Liberty through consummation of the Merger,

the Reorganization Agreement provides that Middlefield will consult with Liberty about forming a Northeast Ohio Advisory Board, which would include some of Liberty’s current directors, and

the Reorganization Agreement preserves for six years the rights of Liberty’s officers and directors to continued indemnification coverage and continued coverage under directors’ and officers’ liability insurance policies.

Each of Middlefield’s and Liberty’s board of directors was aware of these interests and considered them in approving the Reorganization Agreement and the transactions contemplated by the Reorganization Agreement. See “THE MERGER–Interests of Liberty Directors and Executive Officers in the Merger” beginning on page 72 of this joint proxy statement/prospectus.

Dissenters’ rights of Liberty stockholders (page )48)

The National Bank Act gives Liberty stockholders the right to dissent from the Merger and elect to have the fair market value of their shares appraised, receiving payment for their shares in cash. To assert dissenters’ rights of appraisal, a stockholder must comply with the requirements of the National Bank Act, which include voting against the proposal to adopt and approve the Reorganization Agreement and approve the transactions

A Liberty stockholder who has questions regarding dissenters’ rights should consult his or her legal advisers.

Differences in stockholder rights (page )91)

Liberty stockholders who receive Middlefield common stock will be Middlefield stockholders when the Merger is completed. As such, their rights will be governed by Middlefield’s Second Amended and Restated Articles of Incorporation and Regulations, as well as Ohio law.

Applications for the required approvals have been submitted but none have yet been approved. Middlefield is also seeking from the Board of Governors of the Federal Reserve System waiver of the obligation to file an application under the Bank Holding Company Act of 1956.

Middlefield and Liberty desire to complete the Merger byin the ~~end~~first quarter of ~~2016, although neither Middlefield nor Liberty can be certain as to when the regulatory approvals might be obtained.~~2017.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED CONSOLIDATED FINANCIAL DATA

The following unaudited pro forma condensed combined consolidated balance sheet as of ~~June~~September 30, 2016 and the unaudited pro forma condensed combined consolidated statements of income for the ~~six~~nine months ended ~~June~~September 30, 2016 and for the year ended December 31, 2015 are based on the historical financial statements of Middlefield and Liberty after giving effect to the Merger. The Merger will be accounted for using the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, “Business Combinations” (“ASC 805”).

The unaudited pro forma condensed combined consolidated statements of income for the ~~six~~nine months ended ~~June~~September 30, 2016 and for the year end December 31, 2015 give effect to the ~~merger~~Merger as of the beginning of all periods presented. The unaudited pro forma condensed combined consolidated balance sheet as of ~~June~~September 30, 2016 ~~assumed~~assumes that the ~~merger~~Merger took place on ~~June~~September 30, 2016.

The unaudited condensed combined consolidated balance sheet and statement of income as of and for the ~~six~~nine months ended ~~June~~September 30, 2016 were derived from Middlefield’s unaudited condensed financial statements and Liberty’s unaudited condensed financial statements and as of and for the ~~six~~nine months ended ~~June~~September 30, 2016.

The Merger

Upon consummation of the Merger ~~we expect~~Middlefield Banc Corp. will continue to operate as a bank holding company under ~~the name Middlefield Banc Corp.~~that name. Pursuant to the Reorganization Agreement, Liberty will merge with and into The Middlefield Banking Company, a subsidiary of Middlefield, with The Middlefield Banking Company being the surviving entity and remaining Middlefield’s wholly owned subsidiary.

Basis of Presentation

The unaudited pro forma condensed combined consolidated financial statements have been prepared based on Middlefield’s and Liberty’s historical financial information.

UNAUDITED COMPARATIVE PER SHARE DATA

The following table summarizes selected share and per share information about Middlefield and Liberty, giving effect to the Merger (known as “pro forma” information). The data in the table should be read together with the financial information and the financial statements of Middlefield and Liberty incorporated by reference or included in this joint proxy statement/prospectus. The pro forma information is presented as an illustration only, does not represent actual combined financial position per share or combined results of operations per share, and is not a forecast of the combined financial position or combined results of operations for any future period.

The information about book value per share and shares outstanding assumes that the Merger took place as of the dates presented and is based on the assumptions set forth in the preceding unaudited pro forma condensed combined consolidated balance sheets. The information about dividends and earnings per share assumes that the Merger took place as of the beginning of the periods presented and is based on the assumptions set forth in the preceding unaudited pro forma condensed combined consolidated income statements. No pro forma adjustments have been included to reflect potential effects of the Merger related to integration expenses, cost savings, or operational synergies Middlefield expects by combining the operations of Middlefield and Liberty, or to reflect the costs of combining the companies and their operations other than Merger-related expenses. It is further assumed that Middlefield will pay a cash dividend after completion of the Merger at the annual rate of $1.20 per share. The actual payment of dividends is subject to numerous factors, and no assurance can be given that Middlefield will pay dividends after the Merger or that dividends will not be reduced in the future.

This does not take into account the special dividend of approximately $3.0 million, to be declared before closing of the Merger. The cash portion of the Merger consideration is fixed at $37.96 per share, and the stock portion also is fixed at 1.1934 shares of Middlefield common stock for each share of Liberty common stock exchanged for stock. Changes in the price of Middlefield common stock before the Merger is completed will affect the value of the stock portion of the Merger consideration. Changes may result from many factors, including but not limited to general market and economic conditions and changes in Middlefield’s business, operations, and prospects. Therefore, when Liberty stockholders vote on the Merger they will not know the final aggregate value of the Merger consideration to be received. Liberty stockholders should obtain current sale prices for Middlefield common stock before voting at the Liberty annual meeting.

You may receive a form of consideration different from the form of consideration you elect

Under the terms of the Reorganization Agreement, stockholders of Liberty will be entitled to receive, for each share of Liberty common stock: (i) $37.96 in cash, or (ii) 1.1934 Middlefield common shares, or (iii) a combination of both. The form of consideration to be received by each Liberty stockholder is subject to reallocation in order to ensure that approximately 45% of the ~~Merger consideration~~Liberty shares of common stock exchanged in the merger will ~~consist of~~be exchanged for Middlefield’s common shares and 55% of the ~~Merger consideration~~Liberty shares of common stock exchanged in the merger will ~~consist of~~be exchanged for cash. The Reorganization Agreement contains proration and allocation methods to achieve this result. If you elect to receive all cash and the available cash is oversubscribed, then you may receive a portion of the Merger consideration in the form of Middlefield common shares. If you elect to receive all Middlefield common shares and the available common shares are oversubscribed, then you may receive a portion of the Merger consideration in cash. If you elect a combination of cash and Middlefield’s common shares, you may not receive the specific combination you request.

Middlefield could experience difficulties managing its growth and effectively integrating the operations of Liberty.

The earnings, financial condition and prospects of Middlefield after the Merger will depend in part on Middlefield’s ability to integrate successfully the operations of Liberty and continue to implement Middlefield’s business plan. Middlefield may not be able to fully achieve its strategic objectives and projected operating efficiencies. The costs or difficulties of integrating Liberty with the Middlefield organization may be greater than expected or the cost savings from anticipated economies of scale of the combined organization may be lower or take longer to realize than expected. Inherent uncertainties exist in integrating the operations of an acquired entity, and Middlefield may encounter difficulties, including but not limited to loss of key employees and customers, disruption of its ongoing business, or possible inconsistencies in standards, controls, procedures, and policies. These factors could contribute to Middlefield not fully achieving its anticipated benefits of the Merger.

The Reorganization Agreement limits Liberty’s ability to pursue alternatives to the Merger.

With limited exceptions, the Reorganization Agreement prohibits Liberty from soliciting, negotiating, or providing confidential information to any third party relating to competing proposals for acquisition of Liberty. In addition, Liberty must pay $1.65 million to Middlefield for termination of the Reorganization Agreement if (a) Middlefield terminates the Reorganization Agreement because Liberty accepts another acquisition proposal, or withdraws its recommendation or fails to recommend to the stockholders adoption of the Reorganization Agreement, or breaches the prohibition against soliciting other acquisition proposals, or (b) Liberty terminates the Reorganization Agreement with the intention of accepting an alternate, superior proposal. Liberty’s obligation to make the payment could discourage another company from making a competing proposal.

The circumstances of Liberty and Middlefield may have changed since the date of the fairness opinions obtained from Liberty’s and Middlefield’s financial advisors.

Liberty’s board of directors received an opinion dated July 27, 2016 from its financial advisor and Middlefield’s board received a July 27, 2016 opinion from its financial advisor concerning the fairness of the Merger consideration from a financial point of view. Subsequent changes in the operation and prospects of Liberty or Middlefield, changes in general market and economic conditions, and other factors that may be beyond the control of Liberty or Middlefield could significantly alter the value of Liberty or Middlefield or the price of Middlefield common stock by the time the Merger is completed. The opinions state that the Merger consideration is fair from a financial point of view on the date of the opinion, not as of the date the Merger is finally completed or as of any other date. The opinion of Liberty’s financial advisor is attached as Annex C to this joint proxy statement/prospectus. The opinion of Middlefield’s financial advisor is attached as Annex D. For a description of the opinions, see “THE MERGER– Opinion of Liberty’s Financial Advisor” on page 55 and “THE MERGER– Opinion of Middlefield’s Financial Advisor” on page 63 of this joint proxy statement/prospectus.

Middlefield and Liberty stockholders will have a reduced ownership and voting interest after the Merger and will exercise less influence over management of the combined organization.

The Merger will dilute the ownership position of Middlefield stockholders and result in Liberty’s stockholders having an ownership stake in the combined company that is smaller than their current 100% stake in Liberty. Upon completion of the Merger, we estimate that continuing Middlefield stockholders will own approximately ~~81.3%~~80% of the issued and outstanding common stock of Middlefield, while former Liberty stockholders will own approximately ~~18.7%~~20%. Middlefield stockholders and Liberty stockholders will therefore have less influence over the management and policies of the post-Merger organization than they currently have.

Failure to complete the Merger could adversely affect the value of Liberty common stock and future businesses and financial results of both Middlefield and Liberty.

If the Merger is not completed, the ongoing businesses of Middlefield and Liberty could be adversely affected. Middlefield and Liberty would be subject to several risks, including:

In addition, if the Merger is not completed, Middlefield and Liberty may experience negative reactions from their respective customers and employees. Employees could resign and obtain other employment as a result of the potential Merger or failure to complete the Merger. Middlefield or Liberty also could be subject to litigation related to failure to complete the Merger.

The Middlefield common stock received by Liberty stockholders upon completion of the Merger will have different rights from Liberty shares.

When the Merger is completed, Liberty stockholders receiving the stock form of Merger consideration will no longer be stockholders of Liberty but will instead be Middlefield stockholders, with rights governed by the Ohio Revised Code and Middlefield’s articles of incorporation and regulations, which are in some respects materially different from the terms of Liberty’s Bylaws and Amended and Restated Articles of Association. See“COMPARISON OF RIGHTS OF LIBERTY AND MIDDLEFIELD STOCKHOLDERS”on page 91 of this joint proxy statement/prospectus.

Liberty directors and certain of Liberty’s officers have interests that are different from, or in addition to, interests of Liberty’s stockholders ~~generally~~generally.

The directors and certain executive officers of Liberty have interests in the Merger that are different from, or in addition to, the interests of Liberty stockholders generally. These interests include covenants in the Reorganization Agreement providing for the election of two current Liberty directors (Messrs. Valerian and Bevan), to the Middlefield board of directors immediately after the Merger is consummated, indemnification and insurance for directors and officers of Liberty for events occurring before the Merger as well as the possible formation of a Northeast Ohio Advisory Board that would include some current Liberty directors. In addition, the Reorganization Agreement provides for retention payments to be made to certain officers and the payment of amounts due under employment agreements with Liberty’s Chairman and President and with its Chief Operating Officer and Chief Financial Officer.

Liberty will be subject to business uncertainties and contractual restrictions while the Merger is pending.

Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on Liberty and consequently on Middlefield. These uncertainties may impair Liberty’s ability to attract, retain and motivate key personnel until the Merger is consummated, and could cause customers and others that deal with Liberty to seek to change existing business relationships with Liberty. Retention of certain employees may be challenging during the pendency of the Merger, as certain employees may experience uncertainty about their future roles with Middlefield. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Middlefield, Middlefield’s business following the Merger could be harmed. In addition, the Reorganization Agreement restricts Liberty from making certain acquisitions and taking other specified actions until the Merger occurs without the consent of Middlefield. These restrictions may prevent Liberty from pursuing attractive business opportunities that may arise prior to the completion of the Merger. Please see the section entitled “THE REORGANIZATION AGREEMENT– Covenants and Agreements” beginning on page 79 of this proxy statement/prospectus for a description of the restrictive covenants to which Liberty is subject under the Reorganization Agreement.

~~Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or cannot be met.~~

Before the transactions contemplated in the Reorganization Agreement may be completed, various approvals must be obtained from the bank regulatory and other governmental authorities. In determining whether to grant these approvals, the regulators consider a variety of factors, including the regulatory standing of each party and the factors described under “~~THE MERGER~~–~~Regulatory Approvals Required~~” starting on page of this joint proxy statement/prospectus. An adverse development in either party’s regulatory standing or these factors could result in an inability to obtain one or more approvals or delay their receipt. These governmental

entities may impose conditions, limitations or costs, or place restrictions on the conduct of Middlefield after the closing as a condition to the granting of such approvals or require changes to the terms of the Merger. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying completion of the Merger or of imposing additional costs or limitations on Middlefield following the Merger, any of which might have an adverse effect on Middlefield following the Merger. The regulatory approvals may not be received, may not be received in a timely fashion, and may contain conditions on the completion of the Merger that adversely affect the surviving corporation’s business following the closing, or which are not anticipated or cannot be met.

Completion of the Merger is subject to many conditions and if these conditions are not satisfied or waived, the Merger will not be completed.

The obligation of Middlefield and Liberty to complete the Merger is subject to the fulfillment or written waiver of many conditions, including approval by the requisite vote of Middlefield and Liberty stockholders, ~~receipt of regulatory approvals,~~ absence of orders prohibiting completion of the Merger, effectiveness of the registration statement of which this document is a part, approval for Nasdaq Stock Market (“Nasdaq”) listing of the Middlefield shares to be issued, continued accuracy of the representations and warranties of the parties, and performance by the parties of

covenants and agreements. See “THE REORGANIZATION AGREEMENT– Conditions to the Merger”on page 88 of this joint proxy statement/prospectus. These conditions to the consummation of the Merger might not be fulfilled, and the Merger therefore might not be completed. If the Merger is not completed by May 30, 2017 (or a later date the parties may agree to), either Middlefield or Liberty could choose not to proceed with the Merger. The parties also could mutually decide to terminate the Reorganization Agreement at any time, before or after approval by stockholders. In addition, Middlefield or Liberty could elect to terminate the Reorganization Agreement in other circumstances. See“THE REORGANIZATION AGREEMENT– Termination; Termination Fee”on page 89 of this joint proxy statement/prospectus for details or refer to Article 10 of the Reorganization Agreement attached as Annex A.

You should read and consider risk factors specific to Middlefield’s business that will also affect the combined company after the Merger, described in Middlefield’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, all of which are filed by Middlefield with the SEC and incorporated by reference into this document. See “~~INCORPORATION OF DOCUMENTS BY REFERENCE~~~~” on page of this joint proxy statement/prospectus.~~

This joint proxy statement/prospectus ~~and the documents incorporated herein by reference contain~~contains forward-looking statements, including statements about Middlefield’s, Liberty’s, and the post-Merger organization’s financial condition, results of operations, earnings outlook, asset quality trends, and profitability. Forward-looking statements express Middlefield and Liberty management’s current expectations or forecasts of future events. By their nature the forward-looking statements are subject to assumptions, risks, and uncertainties.

In addition, statements in future filings of Middlefield with the SEC, in press releases, and in oral and written statements made by or with the approval of Middlefield or Liberty that are not statements of historical fact constitute forward-looking statements within the meaning of the Reform Act. Examples of forward-looking statements include but are not limited to:

Additional factors that could cause results to differ materially from those described in the forward-looking statements are identified in Middlefield’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the SEC. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters and attributable to Middlefield or Liberty or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements made or referred to above. Forward-looking statements are made only as of the date on which they are made. Middlefield and Liberty are not undertaking to update forward-looking statements.

This joint proxy statement/prospectus is provided to Liberty stockholders by Liberty’s board of directors for solicitation of proxies to be used at the annual meeting of stockholders. The annual meeting will be held at 9:00 a.m. local time on ,December 22, 2016 at ,Corporate College East, 4400 Richmond Road, Warrensville Heights, Ohio ,44128, including any adjournment. This joint proxy statement/prospectus is also being furnished by Middlefield to Liberty stockholders as a prospectus for issuance of Middlefield common stock in the proposed Merger.

Liberty stockholders will be asked at the annual meeting to consider and vote upon proposals to –

Liberty’s board of directors believes the Merger with Middlefield is in the best interests of Liberty stockholders. The board recommends that you vote (1)“FOR”adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, (2) if the adjournment proposal is presented for a vote, “FOR” adjournment to allow additional proxy solicitation, (3) “FOR” election of the identified director nominees, and (4) “FOR” ratification of the selection of independent accountants.

November 25, 2016 is the record date for determining Liberty stockholders entitled to vote at the annual meeting. Only holders of Liberty common stock at the close of business on the record date are entitled to vote at the meeting. As of the close of business on the record date there were shares of Liberty common stock outstanding and entitled to vote. Liberty common stock is held of record by 272 stockholders. Each share of Liberty common stock entitles the holder to one vote on all matters properly presented at the meeting. Stockholders are not entitled to vote cumulatively in the election of directors.

Adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement ~~requires~~require the affirmative vote of the holders of at least two-thirds of the shares of Liberty common stock outstanding. When the stockholder meeting is held, if there are insufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement the meeting may be adjourned to allow solicitation of additional proxies. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to approve adjournment. For the proposal to elect directors, directors are elected by plurality vote,

which means the ~~director~~directors receiving the greatest ~~number~~numbers of votes are elected. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to ratify selection of Liberty’s independent accountants.

If you are a Liberty stockholder and you do not return a proxy card or vote in person at the Liberty annual meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, this will have the same effect as a vote “AGAINST” the proposal. Marking your proxy card or ballot “ABSTAIN” will have the same effect as a vote “AGAINST” the adjournment proposal and the auditor ratification proposal. Failure to return your proxy card or vote in person will have no effect on the adjournment proposal, the proposal to elect directors, or the proposal to ratify the auditor selection.

If you hold your Liberty stock in “street name” through a broker, bank, or other nominee, you must provide your broker, bank, or nominee with voting instructions. Under ~~Nasdaq~~applicable FINRA and stock exchange rules, brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals ~~Nasdaq considers~~stock exchanges consider “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Broker non-votes occur when a broker or nominee does not receive voting instructions from the beneficial owner. Except for the auditor ratification proposal, Liberty believes the proposals to be voted on at Liberty’s annual meeting are “non-routine” and that brokers therefore will not be able to vote on those proposals without specific voting instructions. Therefore, if you hold Liberty shares in street name but do not give voting instructions to your broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, the proposal to adjourn the meeting, or the proposal to elect directors.

Broker non-votes will have the same effect as votes “AGAINST” the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and the proposal to adjourn the meeting. Failing to give voting instructions also will prevent the broker, bank, or other nominee from voting on the director election proposal, but directors nevertheless will be elected because directors are elected by a plurality. Your broker, bank, or other nominee will be able to vote on the auditor selection proposal without voting instructions. Your broker, bank, or other nominee will provide you with a proxy card and directions for giving voting instructions. Please follow the broker, bank, or other nominee’s directions to give voting instructions.

A quorum will exist at Liberty’s annual meeting if a majority of the outstanding common stock is represented in person or by proxy. A quorum must be present in person or by proxy at the meeting before any action other than adjournment can be taken. A properly executed proxy card marked“ABSTAIN”will be counted for purposes of determining whether a quorum is present.

All of Liberty’s directors agreed to vote their Liberty shares in favor of adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, in favor of the adjournment proposal and in favor of entering into Voting Agreements with Middlefield as a condition to Middlefield’s agreement to enter into the Reorganization Agreement. Excluding Liberty shares held by their immediate family members, Liberty’s directors collectively own ~~278,997~~354,986 shares of Liberty common stock, or approximately ~~29.1%~~34.3% of the shares outstanding. ~~They have the right to acquire an additional 75,989 shares, and if they do so those additional shares also are subject to the Voting Agreement.~~ As a holder of 23,218 shares of Liberty common stock, or ~~2.4%~~2.2%, Middlefield intends to vote in favor of adoption and approval of the Reorganization Agreement and approval of the transactions contemplated therein, in favor of the adjournment proposal if applicable, in favor of electing the director nominees identified in this joint proxy statement/prospectus, and in favor of ratifying the selection of independent auditors.

A proxy card accompanies this joint proxy statement/prospectus. If you are a Liberty stockholder your proxy is being solicited by Liberty’s board of directors. Regardless of whether you attend the annual meeting, the Liberty board of directors urges you to return your properly executed proxy card as soon as possible. If you return your properly executed proxy card before the meeting and do not revoke it, the shares of Liberty common stock represented by the proxy card will be voted at the annual meeting or adjournment.

The Liberty common stock will be voted as specified on the proxy card. If you are a Liberty stockholder and you sign, date, and return a proxy card without stating how you want your shares to be voted, your shares will be voted “FOR” adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment. Similarly, your shares will be voted “FOR” election of the identified director nominees and “FOR” ratification of the auditor selection if you return a valid proxy card without giving voting instructions. Although Liberty’s board currently does not expect any other proposals to be presented at the meeting, if any other proposals are properly presented the Liberty common stock represented by properly executed proxy cards will, to the extent permitted by applicable law, be voted in the discretion of the persons named in the proxy card in accordance with their best judgment.

If you return a properly executed proxy card, you may revoke it at any time before a vote is taken at the meeting by:

Attending Liberty’s annual meeting will not, by itself, revoke your proxy. If you instructed your broker, bank, or other nominee to vote your shares but you wish to change or revoke those voting instructions, you must follow your broker, bank, or other nominee’s directions for changing or revoking your vote.

Liberty will bear its own cost of solicitation of proxies. Proxies will be solicited by mail and may also be solicited by personal contact, telephone, facsimile, or electronic mail by directors, officers, and employees, none of whom will receive additional compensation for their solicitation activities. Liberty will pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations, and other custodians, nominees, and fiduciaries who are record holders of Liberty common stock not beneficially owned by them for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to and obtaining voting instructions from the beneficial owners of Liberty common stock.

The board of directors of Liberty, elected by Liberty’s stockholders, oversees the business and management of Liberty. Members of the board monitor and evaluate Liberty’s business performance through regular communication with the CEO and senior management, and by ~~attending~~participating in board and board committee meetings. The Liberty board is committed to sound and effective corporate governance policies and high ethical standards. Under Liberty’s Amended and Restated Articles of Association and By-Laws, the board must consist of at least 5 directors, but may not exceed 25 directors. The By-Laws provide that the number of directors constituting the board may be changed from time to time, either pursuant to a resolution adopted by a majority of the board, or pursuant to the affirmative vote of a majority of the stockholders present in person or by proxy at any meeting of stockholders which has as one of its purposes the election of directors, provided that a quorum is present. The board has fixed the number of authorized directors at thirteen (13). There is currently one vacancy on the board. The board will fill that vacancy when a suitable candidate is ~~identified.~~identified unless the Merger is consummated prior to that time. Twelve seats on the board are currently filled by the individuals identified as directors in the table below, each of whom has been nominated by the board for ~~re-election by action of the board.~~re-election. Each such nominee has consented to being named in this proxy statement and has agreed to serve if elected.

Each director serves for a term ending at the next Annual Meeting of Stockholders following his ~~or her~~ appointment or election as a director, ~~upon the election of successors.~~and until his or her successor is elected and qualified. The term of each of Liberty’s twelve current directors expires at the annual meeting, upon the election of their successors. The board has nominated the twelve current directors for re-election to the board for a term ending upon the earliest of the completion of the Merger, the 2017 annual meeting ~~upon the election of successors,~~and until his successor is elected and qualified, or until he resigns or is otherwise removed and his successor is duly elected and qualified.

Upon the recommendation of the Corporate Governance/Nominating Committee, the board has nominated the twelve individuals identified below for election as directors. The board believes that the qualifications and experience of the 2016 director nominees will contribute to an effective and well-functioning board. The board and the Corporate Governance/Nominating Committee believe that, individually and as a whole, the directors possess the necessary qualifications to provide effective oversight of Liberty’s business and quality advice and counsel to Liberty’s management.

Nominations of candidates for election as directors at the meeting are governed by Liberty’s By-Laws. The By-Laws provide that such nominations may be made either by the board or by any stockholders entitled to vote at a meeting of stockholders at which directors are elected. The By-Laws require that such nominations, if not made by or on behalf of the board, be made in writing and delivered in person or mailed to Liberty’s Secretary and to the ~~OCC~~Office of the Comptroller of the Currency (“OCC”) in Washington, D.C., not less than 14 days nor more than 50 days prior to such meeting. However, if less than 21 days’ notice of such meeting is given to stockholders, such nominations shall be mailed or delivered to the Secretary and to the OCC not later than the close of business on the seventh day following the day on which the notice of meeting was given to stockholders. Notice of the meeting of Liberty’s stockholders is deemed to be given on the date on which such notice is deposited in the United States mail. For the purpose of the herein notice with respect to the meeting, such date is , 2016.

Liberty’s By-Laws further require that nominations for election as director, if not made by or on behalf of the board, set forth the name, address, and the number and class of Liberty common stock owned by the nominating stockholder, and must include all information relating to the proposed nominee that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, including the proposed nominee’s written consent to serve as a director if elected.

Liberty’s By-Laws provide that if the Chairman of the meeting determines that the nomination of any candidate for election as a director was not made in accordance with the By-Laws, then the Chairman may order that such nomination, and all votes cast for the election of such candidate, be disregarded.

Liberty expects that there will be one vacancy on the board following the meeting. In such event, it is the intention of the Board to consider qualified candidates for appointment to the board. As provided by the By-Laws of Liberty, a majority of the board then in office may fill a vacancy on the board.

The following table identifies each director nominee of Liberty. Ages shown are as of ~~September 19,~~November 25, 2016. The term of each current director expires at the meeting, or until he or she resigns or is otherwise removed and his or her successor is duly elected and qualified. There are no family relationships among any of Liberty’s directors.

A majority of the directors and all of the members of the Audit Committee, the Corporate Governance/Nominating Committee, and the Compensation Committee are “independent,” as such term is defined in Rule 5605(a)(2) of the Nasdaq listing standards. Under Nasdaq Rule 5605(a)(2), “independent director” means a person other than an executive officer or employee of Liberty or any other individual having a relationship which, in the opinion of Liberty’s board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. For purposes of this rule, “family member” means a person’s spouse, parents, children and siblings, whether by blood, marriage or adoption, or anyone residing in such person’s home. Under the Nasdaq rule, the following persons shall not be considered independent:

(A)a director who is, or at any time during the past three years was, employed by Liberty;

(B)a director who accepted or who has a family member who accepted any compensation from Liberty in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence, other than the following:

The board has determined that all of the current directors, except for Messrs. Valerian and Ebner, who are executive officers of Liberty, are independent directors within the meaning of the foregoing requirements.

The non-management or independent directors of the board meet periodically in executive session without the directors who are executive officers.

The Audit Committee of Liberty is required to have at least three members, each of whom must comply with the independence and other standards for audit committee members under Nasdaq Rule 5605(c)(2) and Rule 10A-3(b)(1) under the ~~Act.~~Securities Exchange Act of 1934, as amended (the “Act”). The current members of the Audit Committee of the Bank are Michael A. Carlin, Dominic M. D’Amore, Jr. (Chair), Ralph R. Razinger, Thomas A. Reitan and Daniel D. Smith.

Each Audit Committee member must: (i) be “independent” as defined under the Nasdaq director independence rules set forth above; (ii) meet the criteria for independence set forth in Rule 10A-3(b)(1) under the Act (subject to the exemptions provided in Rule 10A-3(c) under the Act); (iii) not have participated in the preparation of the financial statements of Liberty or any current subsidiary of Liberty at any time during the past three years; and (iv) be able to read and understand fundamental financial statements, including Liberty’s balance sheet, income statement, and cash flow statement. Furthermore, at least one member of the Audit Committee has, and will continue to have, past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual’s financial sophistication, including being or having been a chief executive officer, chief financial officer or other senior officer with financial oversight responsibilities. Liberty has determined that Audit Committee members Michael A. Carlin and Dominic M. D’Amore, Jr. meet these requirements.

Members of the board who are not employees of Liberty were compensated for their attendance at meetings of the board during 2015 at the rate of $800 per meeting attended. They received no other compensation for their service on the board. In addition, members of the board who are not employees of Liberty and who served on committees of the board received $275 per meeting attended. Effective January 1, 2016, the compensation for attendance at meetings of the board for members who are not employees of Liberty was increased from $800 to $900 per meeting while compensation for attendance at meetings of committees of the board was increased from $275 to $300 per meeting.

Mr. Valerian was compensated $12,000 in 2015 for his services on the board and the committees on which he serves. Mr. Valerian will be compensated $12,000 in 2016 for his services on the board and the committees on which he serves.

The following table sets forth the compensation paid to the directors who are not employees of Liberty during 2015:

The board met twelve (12) times during 2015. Each director attended at least 75% of the meetings of the board.

From time to time, Liberty extends credit to its directors and executive officers for business and personal uses. All extensions of credit to directors and executive officers are made in the ordinary course of Liberty’s business and on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other borrowers involving similar credit risk. Such credit extensions are made after a determination by the Bank that they do not involve more than the normal risk of collectability or present other unfavorable features.

Liberty’s board of directors recommends voting“FOR” election of the identified director nominees.

As discussed throughout this joint proxy statement/prospectus, Liberty is asking stockholders to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. Liberty stockholders should carefully read this document in its entirety for more detailed information regarding the Reorganization Agreement and the Merger. In particular, stockholders are directed to the copy of the Reorganization Agreement attached as Annex A to this joint proxy statement/prospectus.

Liberty’s board of directors recommends voting“FOR”approval and adoption of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement.

If there are insufficient votes at the time of the Liberty annual meeting to approve and adopt the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, the meeting may be adjourned to another time or place to allow additional time for proxy solicitations. If the number of shares of Liberty common stock voting in favor is insufficient to approve and adopt the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, Liberty intends to move for adjournment to enable the Liberty board of directors to solicit additional proxies for approval. If that occurs, Liberty will ask the Liberty stockholders to vote upon the adjournment proposal (but not the Merger proposal) and will also ask stockholders to vote on the director election proposal and auditor ratification proposal. Liberty is asking stockholders to authorize the proxy holder to vote in favor of adjournment of the Liberty annual meeting to another time and place for the purpose of soliciting additional proxies. If the adjournment proposal is approved, proxies will remain valid if not revoked and Liberty could use the additional time to solicit additional proxies, including the solicitation of proxies from Liberty stockholders who have previously voted.

Liberty’s board of directors recommends voting“FOR”the adjournment proposal.

The Audit Committee of Liberty’s board appointed Maloney + Novotny LLC, Certified Public Accountants, to serve as the Bank’s independent auditors for its fiscal year ending December 31, 2016. The board is seeking stockholder ratification of the Audit Committee’s appointment of Maloney + Novotny LLC. Representatives of Maloney + Novotny LLC are expected to attend the annual meeting to respond to appropriate questions, and will have an opportunity to make a statement if they desire. If the appointment of Maloney + Novotny LLC is not ratified by the stockholders, the Audit Committee may appoint another independent accounting firm or may decide to maintain the appointment of Maloney + Novotny LLC. Notwithstanding the selection and ratification, the Audit Committee, in its discretion, may direct the appointment of a new independent public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of Liberty and its stockholders.

The affirmative vote of a majority of the voting power of the common stock present is necessary for ratification of the selection of independent auditors.

Liberty’s board of directors recommends voting“FOR” ratification of the selection of Maloney + Novotny LLC as independent auditors.

This joint proxy statement/prospectus is provided to Middlefield stockholders by Middlefield’s board of directors for solicitation of proxies to be used at the special meeting of stockholders. The special meeting will be held at 10:00 a.m. local time on ~~, 2016~~January 10, 2017 at ,The Middlefield Banking Company, 15985 East High Street, Middlefield, Ohio ,44062, including any adjournment.

Middlefield stockholders will be asked at the special meeting to consider and vote upon proposals to –

Middlefield’s board of directors believes the Merger is in the best interests of Middlefield stockholders and recommends that you vote (1)“FOR” the Reorganization Agreement, (2)“FOR” issuance of common stock, and (3) ) if the adjournment proposal is presented for a vote,“FOR” adjournment.

The board of directors fixed the close of business on ,November 17, 2016 as the record date for determining Middlefield stockholders entitled to vote at the special meeting. As of the close of business on the record date there were 2,250,893 shares of Middlefield common stock outstanding and entitled to vote at the special meeting. Middlefield common stock is held of record by approximately 1,060 stockholders. Each share of Middlefield common stock entitles the holder to one vote on all proposals at the special meeting.

Under the Ohio General Corporation Law and Middlefield’s Second Amended and Restated Articles of Incorporation, adoption and approval of the Reorganization Agreement requires the affirmative vote of the holders of at least two-thirds of Middlefield’s outstanding common stock. Under Nasdaq rules, approval of the issuance of Middlefield common stock requires the affirmative vote of the holders of a majority of votes cast on the proposal. Under Middlefield’s regulations, approval of adjournment requires the affirmative vote of the holders of a majority of the votes cast on the proposal. On the record date Middlefield directors owned a total of 102,153 shares of Middlefield common stock, or approximately 4.6%.

If you are a Middlefield stockholder and you do not return a proxy card or vote in person at the Middlefield special meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to adopt and approve the Reorganization Agreement, this will have the same effect as a vote “AGAINST” that proposal. Failing to vote or abstaining will have no effect on the adjournment proposal or the proposal to approve issuance of shares.

If you hold your Middlefield stock in “street name” through a broker, bank, or other nominee, please provide your broker, bank, or nominee (the record holder of your common stock) with voting instructions. Under Nasdaq rules, brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their

discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals Nasdaq considers “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Broker non-votes occur when a broker or nominee does not receive voting instructions from the beneficial owner. Middlefield believes the proposals to be voted on at the special meeting are “non-routine” and that brokers therefore will not be able to vote on those proposals without specific voting instructions. Therefore, if you hold Middlefield stock in street name but do not give voting instructions to your broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to adopt and approve the Reorganization Agreement, the proposal to approve share issuance, or the proposal to adjourn the meeting.

Broker non-votes on the proposal to adopt and approve the Reorganization Agreement will have the same effect as votes “AGAINST” that proposal. Failing to give voting instructions also will prevent your broker, bank, or other nominee from voting on the proposal to issue common stock and the adjournment proposal, but under Middlefield’s regulations broker non-votes on those proposals have no effect because the proposals are decided by a majority of votes actually cast. Your broker, bank, or other nominee will provide you with a proxy card and directions for giving voting instructions. Please follow the broker, bank, or other nominee’s directions to give voting instructions.

A quorum will exist at Middlefield’s special meeting if a majority of the outstanding common stock is represented in person or by proxy. A quorum must be present in person or by proxy at the meeting before any action other than adjournment can be taken. A properly executed proxy card marked“ABSTAIN”will be counted for purposes of determining whether a quorum is present.

A proxy card accompanies this joint proxy statement/prospectus. If you are a Middlefield stockholder your proxy is solicited by Middlefield’s board of directors. Regardless of whether you attend the special meeting, the Middlefield board urges you to return your properly executed proxy card as soon as possible. If you return a properly executed proxy card before the special meeting and do not revoke it, the Middlefield common stock represented by the proxy card will be voted at the special meeting or adjournment. The common stock will be voted as specified on the proxy card.

If you are a Middlefield stockholder and you sign, date, and return a proxy card but do not specify how your shares are to be voted, your shares will be voted “FOR” adoption and approval of the Reorganization Agreement and the transactions contemplated thereby, “FOR” issuance of common stock in the Merger, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment. Although Middlefield’s board currently does not expect any other proposals to be presented at Middlefield’s special meeting, if any other proposals are properly presented the common stock represented by properly executed proxy cards will, to the extent permitted by applicable law, be voted in the discretion of the persons named in the proxy card in accordance with their best judgment.

If you return a properly executed proxy card, you may revoke it at any time before a vote is taken at the meeting by:

Attending Middlefield’s special meeting will not, by itself, revoke your proxy. If you instructed your broker, bank, or other nominee to vote your shares but you wish to change or revoke those voting instructions, you must follow your broker, bank, or other nominee’s directions for changing or revoking your vote.

Middlefield will bear its own cost of solicitation of proxies. Proxies will be solicited by mail and may also be solicited by personal contact, telephone, facsimile, or electronic mail by directors, officers, and employees, none of whom will receive additional compensation for their solicitation activities. Middlefield has also engaged D.F. King & Co., a proxy soliciting firm, to assist in the solicitation of proxies for a fee of $15,000 and reimbursement of reasonable out-of-pocket expenses. Middlefield will pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations, and other custodians, nominees, and fiduciaries who are record holders of Middlefield common stock not beneficially owned by them for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to and obtaining proxies from the beneficial owners of Middlefield common stock.

As discussed throughout this joint proxy statement/prospectus, Middlefield is asking its stockholders to adopt and approve the Reorganization ~~Agreement.~~Agreement and approve the transactions contemplated thereby. Middlefield stockholders should read this document carefully in its entirety for more detailed information regarding the Reorganization Agreement and the Merger. In particular, stockholders are directed to the copy of the Reorganization Agreement attached as Annex A to this joint proxy statement/prospectus.

Middlefield’s board of directors recommends voting“FOR”approval and adoption of the Reorganization ~~Agreement.~~Agreement and approval of the transactions contemplated thereby.

Middlefield is also asking stockholders to consider and vote on the proposal to issue up to 563,261 shares of Middlefield common stock in the Merger. A company with Nasdaq-listed stock is required by Nasdaq rules to obtain stockholder approval if a proposed stock issuance equals or exceeds 20% of the number of shares outstanding before the issuance. The number of shares to be issued by Middlefield in the Merger is approximately ~~23%~~25% of the number of shares outstanding, and for this reason Nasdaq rules require Middlefield to seek stockholder approval. If Middlefield stockholders do not approve the common stock issuance, Middlefield will not be able to complete the Merger.

Middlefield’s board of directors recommends voting“FOR”approval of the issuance of up to 563,261 shares of Middlefield common stock in the Merger.

If there are insufficient votes at the time of Middlefield’s special meeting to approve and adopt the Reorganization Agreement, the meeting may be adjourned to another time or place to allow additional time for proxy solicitations. If the number of shares of Middlefield common stock voting in favor is insufficient to approve and adopt the Reorganization Agreement, Middlefield intends to move for adjournment to enable Middlefield’s board to solicit additional proxies for approval. If that occurs, Middlefield will ask stockholders to vote upon adjournment but not the merger proposal or the proposal to approve share issuance. Middlefield is asking stockholders to authorize the proxy holder to vote in favor of adjournment of the Middlefield special meeting to another time and place for the purpose of allowing additional proxy solicitation. If the adjournment proposal is approved, proxies will remain valid if not revoked and Middlefield could use the additional time to solicit additional proxies, including solicitation of proxies from Middlefield stockholders who have previously voted.

Middlefield’s board of directors recommends voting“FOR”the adjournment proposal.

Liberty stockholders are entitled to exercise dissenters’ rights of appraisal under the National Bank Act, 12 U.S.C. §215. A copy of the dissenters’ rights provisions of 12 U.S.C. 215 is attached as Annex B to this joint proxy statement/prospectus. Under these provisions of federal law, Liberty stockholders may dissent from the Merger and elect to have the fair market value of their shares appraised, receiving payment of the appraised value in cash. To assert dissenters’ right of appraisal, a stockholder must vote against the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement or give notice in writing at or before Liberty’s meeting that the stockholder dissents, giving such notice to the presiding officer. The dissenting stockholder must make a written request to Middlefield for payment of the appraised value of his or her shares at any time before 30 days after Merger consummation, accompanied by surrender of his or her stock certificates.

The value of a dissenter’s Liberty shares will be determined by a committee of three persons, including one selected by a majority vote of the dissenting stockholders, one selected by the directors of The Middlefield Banking Company, and the third by the two so chosen. The valuation agreed upon by any two of these three appraisers governs, but if the value fixed by the appraisers is not satisfactory to a dissenting stockholder, the stockholder may within five days after being notified of the appraised value of his or her shares appeal to the ~~Office of the Comptroller of the Currency (OCC),~~OCC, which will cause a reappraisal to be made. The OCC’s reappraisal will be final and binding. If within 90 days after the effective date of the Merger one or more of the appraisers is not selected or the appraisers fail to determine the value of the dissenting shares, upon written request of any interested party the OCC will cause an appraisal to be made, which will be final and binding on all parties. The expenses of the OCC in making the appraisal or reappraisal will be paid by The Middlefield Banking Company.

This summary of dissenters’ rights is qualified in its entirety by reference to the statutory provisions of 12 U.S.C. 215, paragraphs (b) through (d), reproduced in Annex B. Failure by a Liberty stockholder to follow the required steps for perfecting rights as a dissenting stockholder will result in a loss of those rights. Stockholders’ ~~notice~~notices of intent to demand appraisal of and payment for their shares should be sent to: William A. Valerian, Chairman, President and Chief Executive Officer, Liberty Bank, N.A., 25201 Chagrin Boulevard, Suite 120, Beachwood, Ohio 44122. When the Merger is completed, before the 30^th day after completion of the Merger stockholders who have properly asserted dissenters’ rights should request in writing to Middlefield that it pay the appraised value of their shares, surrendering their stock certificates to Middlefield at that time. The written request after the Merger should be sent to: Thomas G. Caldwell, President and Chief Executive Officer, The Middlefield Banking Company, 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.

The Reorganization Agreement provides for the merger of Liberty into The Middlefield Banking Company with The Middlefield Banking Company being the surviving entity. As part of the transaction, MBC Interim Bank will first merge into Liberty, followed immediately by Liberty’s merger into The Middlefield Banking Company.

The Reorganization Agreement is attached to this joint proxy statement/prospectus as Annex A and is ~~incorporated in~~an integral part of this joint proxy statement/~~prospectus by reference.~~prospectus.You are encouraged to read the Reorganization Agreement carefully. The Reorganization Agreement is the principal legal document governing the Merger.

Retained by Liberty as financial advisor for a possible strategic transaction, in March 2016 Boenning & Scattergood, Inc. (“Boenning”) invited financial organizations – including Middlefield – to review a confidential information memorandum concerning Liberty and to submit an initial acquisition bid, with an April 18, 2016 deadline for non-binding indications of interest. Executing the March 21, 2016 confidentiality agreement, Middlefield received a copy of Boenning’s confidential information memorandum. After reviewing the confidential information memorandum, Middlefield management declined to submit a bid. Beginning with the financial crisis of 2007 and 2008 merger and acquisition activity for financial institutions remained for many years at greatly reduced levels by comparison to the ten-year period ended in 2006, with much of the post-crisis activity involving acquisitions of problem institutions or sales of control to private equity firms. But by the end of 2015 the pace of healthy financial institution acquisitions was again accelerating. This was one of the factors that led Middlefield management to initially decline submitting a bid for Liberty, believing a very competitive bidding process would lead to deal terms outside the range sanctioned by Middlefield’s internal policies.

In the first half of 2016 Middlefield management’s attention was focused on raising additional equity in a private offering. Middlefield engaged Boenning to assist with the private equity offering, entering into a letter agreement with Boenning ~~& Scattergood~~ on February 12, 2016, later superseded by an April 27, 2016 Placement Agency Agreement. Under the letter agreement and Placement Agency Agreement, Boenning acted as Middlefield’s exclusive placement agent. A private placement to accredited investors only of no more than 20% of Middlefield’s common stock outstanding, the private offering began on or about May 2, 2016 and ended June 30, 2016. Middlefield sold to 29 accredited investors a total of 360,815 shares at $33 per share, or approximately 19% of the shares outstanding before the private placement and 16% of the shares outstanding after. Middlefield’s net proceeds of the private offering were $11.3 million, after commissions of approximately $577,000 payable to Boenning and reimbursement of $20,245 of Boenning expenses. With the proceeds of the private placement Middlefield repaid borrowings, including a $3.0 million line of credit from Liberty. If within 24 months after the end of the private offering Middlefield raises additional equity from an investor contacted by Boenning, Boenning will be entitled by the Placement Agency Agreement to a commission at the same rate applicable to the 2016 private sales. Boenning is entitled to indemnification from Middlefield for liabilities arising out of the private offering, as well as contribution by Middlefield to the damages, costs, and expenses that may be incurred by Boenning. Boenning has the right of first refusal to act as Middlefield’s placement agent if Middlefield engages in a rights offering to stockholders at any time before July 1, 2017, with a 5.0% commission rate on sales to persons who became Middlefield stockholders through the private offering and a reduced commission rate for sales to directors, executives, and other stockholders.

Middlefield also has an investment banking relationship of long standing with Donnelly Penman & Partners Inc. In early April 2016, after Middlefield management initially declined Boenning’s invitation to bid on the Liberty transaction, Donnelly Penman informed Middlefield management that a number of other potential

bidders also had declined to submit bids because of other acquisition transactions or for other reasons not having

to do with Liberty. With a reduced number of potential bidders, Donnelly Penman suggested that management reconsider the decision not to submit a bid, outlining in very general terms a deal proposal management could consider making. Management discussed this with the Executive Committee of the board of directors of Middlefield at a meeting on Tuesday, April 12, 2016, a meeting at which the principal item of business was the private placement transaction that management desired to complete. The directors on the Executive Committee were Directors Turk, Skidmore, Caldwell, and Heslop. Director Darryl Mast also joined the meeting.

The Executive Committee and Director Mast convened again two days later, on April 14, 2016, to discuss the Liberty proposal, with representatives of Donnelly Penman present as well. At this meeting a deal proposal was outlined by Donnelly Penman and discussed at length, with consideration given to transaction-related costs such as the cost of Liberty’s data processing contract and the costs associated with Liberty’s executive severance arrangements, the future of Liberty’s student loan portfolio, the uncertain status of Liberty’s recently added loan production office in Wooster, Wayne County, Ohio, potential loss of Liberty’s significant deposit customers, the source of funds for the cash component of the potential transaction and the potential dilution resulting from the equity component, the effect of the acquisition on Middlefield’s regulatory capital, and potential cost savings that could result for the combined organization if redundancies are eliminated after acquisition. Aware of the Monday, April 18, 2016, deadline for submitting bid proposals, the committee authorized management to request from Donnelly Penman a post-acquisition financial projection revised to assume loss of Liberty’s two deposit customers, who according to the confidential information memorandum together accounted for deposits of more than $50 million, and sale of Liberty’s student loan portfolio at a slight loss.

On Friday, April 15, 2016 the Executive Committee – Directors Turk, Skidmore, Caldwell, and Heslop – reviewed Donnelly Penman’s revised projections of financial results. The committee concluded that the overall effect of the revised assumptions was not materially adverse, noting that the period to earn back the dilution of Middlefield’s tangible book value and the period in which the transaction becomes accretive to Middlefield’s earnings are within Middlefield’s internal guidelines, although the tangible book value dilution is slightly outside of the guidelines’ recommended range. Authorizing management to submit a nonbinding bid at the price of 125% of Liberty’s tangible book value, the committee instructed management that the bid must be subject to the condition that Liberty sell its student loan portfolio and declare a special cash dividend before acquisition closing to reduce excess capital.

With a 24-hour extension for submitting the indication of interest, the same Executive Committee members met again on Monday, April 18, 2016, to finalize Middlefield’s bid, with Donnelly Penman participating by telephone conference. Subject to obtaining legal review, the Executive Committee authorized management to submit to Boenning ~~& Scattergood~~ a bid in the form of a nonbinding letter of intent, with a total transaction value in the range of approximately 125% to 130% of tangible book value, or 137.5% to 145.0% of tangible book value adjusted for the proposed special cash dividend. Recognizing that Liberty stockholders would possess approximately 17% of Middlefield’s outstanding stock after the acquisition, Middlefield agreed to offer two board seats to Liberty, one at the level of the holding company and another at the level of The Middlefield Banking Company. Middlefield submitted its bid by the Tuesday, April 19, 2016 deadline.

On April 19, 2016 Boenning ~~& Scattergood~~ informed Middlefield that it was one of four bidders (three banks and one individual investor) being invited to perform due diligence and thereafter to submit a final bid. Middlefield submitted its due diligence request list to Boenning ~~& Scattergood~~ on April 22, 2016

CEO Thomas G. Caldwell updated the board at its May 9, 2016 regular meeting about the status of Middlefield’s indication of interest. CEO Thomas G. Caldwell, COO James R. Heslop, II, and CFO Donald L. Stacy met on Thursday, May 12, 2016, with Liberty’s board of directors, the day immediately after Middlefield’s 2016 annual meeting, outlining for the benefit of Liberty’s board the terms of Middlefield’s acquisition proposal. Middlefield representatives performed on-site due diligence of Liberty on May 9, 10, and 11, and during this period and thereafter Middlefield and its advisors made use of ~~Boenning & Scattergood’s~~Boenning’s electronic

data room, where books and records of Liberty were available confidentially. On May 20, 2016 CEO Thomas G. Caldwell

had a breakfast meeting at which he was introduced by Liberty’s CEO William A Valerian to Director Thomas W. ~~Bevan~~Bevan. Mr. Bevan is not only a director of Liberty but also controls an organization that is one of Liberty’s two largest depositors.

Middlefield’s Executive Committee met again on May 25, 2016, with Directors Turk, Skidmore, Caldwell, and Heslop and with Director Mast added to the Executive Committee’s membership. Representatives of Donnelly Penman attended the May 25, 2016 meeting by teleconference. The committee noted with approval that the Liberty acquisition would give Middlefield the opportunity to achieve its goal of entering the Cuyahoga County and Summit County markets, add SBA lending expertise to Middlefield’s lending products and services, generate income through sale of the government-guaranteed portion of SBA loans into the secondary market, and with Liberty’s student loan product constitute another potential addition to Middlefield’s loan products and services. Donnelly Penman discussed its updated merger analysis, slightly decreasing its estimate of the post-acquisition value of Liberty’s loan portfolio, reducing the estimated loss of deposits after the acquisition, which is referred to as deposit runoff, and slightly reducing the estimated severance benefits payable to Liberty executives as a result of the acquisition. Donnelly Penman’s updated analysis also took into account Middlefield’s ongoing private placement, which would strengthen Middlefield’s capital position, and presented updated projections of Middlefield’s financial condition on a stand-alone basis (stand-alone meaning without taking the ~~merger~~Merger into account).

For the final bid Donnelly Penman outlined a proposed price of 145% of Liberty’s adjusted tangible book value, for a total transaction value of approximately $39.6 million, including a $12.5 million special dividend payable by Liberty before closing, with 50% of the merger consideration consisting of cash and the other half Middlefield stock. The requirement that Liberty sell the student loan portfolio was no longer part of Middlefield’s proposal, because the portion of Liberty’s student loan portfolio maintained on Liberty’s books performs satisfactorily and the portion originated for sale has significant associated correspondent deposit balances maintained at Liberty by the parties to whom Liberty sells the loans. The May 25 meeting ended with the committee agreeing to recommend that the full board approve the proposed transaction terms at the board’s June 6 special meeting, one day before the June 7 final bid deadline. Donnelly Penman met again with the Executive Committee on June 1, 2016, updating the committee about the status of the letter of intent.

CEO Thomas G. Caldwell updated the board at its June 6 special meeting about the bid process. Donnelly Penman and Middlefield’s counsel joined the meeting by teleconference. By this time two of the four bidders invited to submit a final bid dropped out, leaving Middlefield and one unknown bidder remaining. Based on conversations with Thomas W. Bevan, a director of Liberty and one of its two largest depositors, the projected deposit runoff calculated by Donnelly Penman was reduced again. Mr. Caldwell noted favorably to the board that Liberty and Middlefield have a community banking focus in common, that Liberty does not have material asset quality concerns, that the due diligence process revealed nothing negative about Liberty, that Liberty’s offices are located in Middlefield’s targeted area of expansion, and that Liberty’s SBA lending would expand Middlefield’s products and potentially generate income from sale of the government-guaranteed portion of the SBA loans. For the proposed final bid, the period to earn back the estimated 16.5% dilution of Middlefield’s tangible book value and the period in which the transaction becomes accretive to Middlefield’s earnings remained within Middlefield’s internal guidelines, but the tangible book value dilution remained slightly outside of the guidelines’ recommended range. The board’s special meeting ended with unanimous approval for management to submit a final bid on the terms outlined at the meeting, at 145% of Liberty’s adjusted tangible book value, or approximately $40.54 per share (including the amount of the special dividend).

Middlefield submitted its final bid in the form of a nonbinding letter of intent on June 6, 2016. Liberty informed Middlefield that the final bids would be reviewed at Liberty’s board meeting on Friday, June 10. After the June 10 board meeting, at Liberty’s request Boenning ~~& Scattergood~~ informed Donnelly Penman that Liberty’s counterproposal was to obtain two holding company board seats at Middlefield, a $1.00 per share increase in the bid price, and a continued interest in future recoveries on previously charged off student loans.

At a special meeting of Middlefield’s board on Monday, June 13, with Donnelly Penman and Middlefield’s counsel joining by teleconference, the board approved a final offer, agreeing to add CEO William A. Valerian and Director Thomas W. Bevan to Middlefield’s board and agreeing to a price increase of approximately $0.55 per share, half in additional cash and half in additional Middlefield stock, but declined to offer Liberty a continued interest in future recoveries of previously charged off loans. The letter of intent also provided for continued indemnification and insurance coverage of Liberty’s officers and directors for six years after the transaction. Middlefield’s board also made clear that the company’s willingness to enter into a definitive acquisition agreement was conditioned on Liberty directors executing voting agreements, committing themselves to vote their Liberty shares in favor of the transaction with Middlefield.

Promptly after the June 13 special meeting Donnelly Penman informed Boenning ~~& Scattergood~~ of Middlefield’s final offer. Middlefield’s letter of intent was signed and returned by Liberty on June 14, 2016, and the parties then proceeded to negotiation of the definitive Reorganization Agreement. The letter of intent provided for the merger of Liberty into The Middlefield Banking Company in a transaction qualifying as a tax-free reorganization, at the price of 147% of Liberty’s adjusted tangible May 31, 2016 book value. Excluding approximately $1.147 million payable for cancellation of Liberty’s outstanding options and phantom stock, total transaction consideration under the final letter of intent was approximately $39.416 million, consisting of (1) $12.5 million in the form of a special cash dividend before acquisition closing, (2) $13.458 million in cash merger consideration, and (3) $13.458 million in stock merger consideration at a 0.882 fixed exchange ratio of Middlefield stock for 50% of Liberty stock, based on the $31.81 closing price for Middlefield stock on June 13, 2016.

Subsequently, Liberty’s outside tax counsel reviewed Middlefield’s revised indication of interest and, after consultation with and concurrence from Middlefield’s outside tax counsel, determined that the proposed payment by Liberty of a $12.5 million dividend to its stockholders immediately prior to completion of the Merger would adversely affect the tax-free reorganization treatment of the Merger and the ability of Liberty’s tax counsel to issue a favorable tax opinion. Following further discussions among the parties and their counsel, it was determined that the transaction should be restructured to reduce the Liberty special dividend from $12.5 million to approximately $3.0 million, increase the cash portion of the Merger consideration from 50% to 55% and decrease the common shares portion of the Merger consideration to 45%, while maintaining the same total transaction value. Over the next several weeks, the parties revised the draft Reorganization Agreement to reflect the latest structure of the transaction and negotiated its terms and conditions.

At a July 11, 2016 special meeting, with counsel present and Donnelly Penman present by teleconference, the board reviewed the status of the proposed transaction and the progress toward execution of the definitive acquisition agreement. Donnelly Penman presented a revised analysis of the transaction consideration, reducing from $12.5 million to $3.0 million the amount of the special cash dividend payable to Liberty stockholders before closing and increasing the portion of the cash merger consideration from 50% to 55%, with the stock portion therefore decreasing to 45%, while maintaining the total transaction value. According to Donnelly Penman’s analysis of the revised final terms, Liberty stockholders would have a slightly larger 18.7% stake in the combined Middlefield organization after acquisition, rather than the initial estimate of approximately 17%, Middlefield would earn back the tangible book value dilution within the time range sanctioned by Middlefield’s internal policy, and Middlefield’s regulatory capital ratios would be within policy limits as well. The slight increase in the number of shares to be issued to Liberty stockholders has the consequence of requiring a vote of Middlefield stockholders as well. The number of shares of Middlefield common stock issuable to Liberty stockholders slightly exceeds 20% of the number outstanding before the acquisition, requiring Middlefield approval under Nasdaq rules, and one-sixth of the number outstanding after the acquisition, requiring stockholder approval under OGCL section 1701.83(A).

On July 25, 2016, Liberty’s on-site due diligence investigation of Middlefield occurred, conducted by management of Liberty as well as a representative of Boenning. Liberty had been reviewing Middlefield’s SEC filings and additional information provided to Boenning, as well as information provided by Middlefield in connection with the May 12 presentation to the Liberty Board.

Middlefield’s board considered the proposed final Reorganization Agreement at a special meeting on July 27, 2016, with Donnelly Penman participating and Middlefield’s counsel present by teleconference. The Reorganization Agreement was signed on July 28, 2016. The board considered the slight change in the transaction structure, with the introduction of a first-step merger of MBC Interim Bank into Liberty occurring immediately before the merger of Liberty into The Middlefield Banking Company. The change in transaction structure is for the sole purpose of minimizing adverse potential tax consequences to The Middlefield Banking Company if the transaction does not qualify for tax-free reorganization treatment. Donnelly Penman presented its fairness opinion to the board and outlined the significant terms and financial impact of the transaction, including a special dividend of $3.13 per share for each of Liberty’s 959,283 outstanding shares, cash merger consideration of $20.88 per share and stock consideration valued at $17.08, for total consideration of approximately $39.1 million (including the special dividend), or $41.09 per share. Donnelly Penman informed the board that tangible book value dilution would be approximately 16.3%, projected to be earned back in a period of less than 3.5 years, with accretion to earnings exceeding 38% in the first year, an internal rate of return exceeding 20%, and a pro forma Tier 1 leverage ratio at The Middlefield Banking Company of 7.71% and a ratio of tangible common equity to tangible assets of 8.32%. Donnelly Penman informed the board that total consideration is approximately 1.31 times Liberty’s tangible book value and 19.12 times last-twelve-months earnings, with a core deposit premium of 5.16%. The July 27, 2016 special meeting concluded with Middlefield’s board approving the Reorganization Agreement unanimously.

The Liberty Board of Directors has regularly reviewed and discussed Liberty’s business strategy, performance and prospects in the context of developments in the banking industry, the regulatory environment and the competitive landscape. Among other things, the board of directors from time to time has discussed various strategic alternatives, including both acquiring other institutions and being acquired by another institution. Based on Liberty’s continued growth, the board of directors believed that it would need to engage in a strategic transaction at some point in time.

For a considerable time, the board of directors of Liberty has been concerned about the increasing expense and complexity of regulatory compliance for financial institutions, as well as the competition among large and small financial institutions for the same loan and deposit products. The directors have discussed in recent years how to best ensure the continued sound operation and profitability of Liberty in the face of these concerns.

Over the years, the board considered from time to time how to best provide for the continued safe and sound operation and strong performance of Liberty in the challenging regulatory and competitive environment. The board also discussed the lack of liquidity of Liberty’s stock as well as management succession issues. These discussions included a number of formal and informal meetings at which the directors discussed, among other possibilities, whether to proceed with exploring the possibility of acquiring or merging with another bank. Board members received the unsolicited views of some Liberty stockholders regarding a need for greater liquidity in the Liberty shares. As a result of these stockholder discussions and the board’s concerns regarding the increasingly challenging competitive and regulatory environment, the board decided to consider the possibility of exploring a merger and to learn more about the current merger and acquisition market.

From time to time over the years, the board invited Boenning to make a presentation about regional and national merger and acquisition activity. During 2015, Boenning reviewed such trends as well as the procedure and timeline for soliciting nonbinding indications of interest from potential merger partners. Boenning also presented a list of bank and thrift holding companies that, according to Boenning’s analysis, might have a logical interest in a possible merger with Liberty. In evaluating whether to proceed with the possibility of soliciting potential merger partners, the board also considered the stated desires of some Liberty stockholders for greater liquidity in Liberty shares and the board’s long-held concerns regarding competition and regulation. After careful consideration of all the foregoing, the directors decided to consider Boenning’s presentation and reconvene at a later time to determine whether to pursue the process of soliciting interest in a possible merger.

At a meeting of the board held on December 14, 2015, the Liberty directors resumed their discussions regarding whether to enter into the process of soliciting interest in a possible merger. After lengthy consideration of all the foregoing factors, and in light of the board’s numerous prior discussions regarding exploring the possibility of a merger, the board unanimously decided to proceed with the process, subject to the agreement and understanding that they could terminate the process at any time before the execution of a definitive agreement in the event that their expectations for stockholder value were not realized.

In January 2016, Boenning was hired by Liberty as its financial advisor to counsel Liberty with respect to a possible strategic transaction. Boenning assisted Liberty in preparing a confidential information memorandum and a limited data room containing certain financial and operational information of Liberty. Liberty and Boenning identified thirty-three (33) potential partners to contact and inquire as to whether such party would be interested in reviewing the memorandum and data room. Of those parties, twenty-two (22) executed confidentiality agreements and accessed the data room and four (4) submitted written indications of interest, three of which were from other banks and one of which was from an individual investor. On April 19, 2016, the board of directors met to consider the four (4) indications of interest. The board of directors reviewed with Boenning the current state of the national and local banking markets, as well as the current environment for bank transactions. The board of directors also reviewed in detail each potential partner’s business, operations and financial performance. The board of directors discussed each of the indications of interest in detail and considered the merits of an all cash offer versus a part-stock, part-cash offer. The board of directors also reviewed and considered the financial and operating performance of each party and considered the effect of each offer on the submitting party’s financial condition. The board, with the advice of Boenning, determined that providing these four (4) bidders the opportunity to continue the due diligence process would maintain a competitive bidding process, while minimizing the potential disruption to Liberty’s operations. Each of the parties subsequently conducted a thorough due diligence process, including on-site meetings with Liberty management and extensive review of materials in the online data room.

At a special meeting of the board of directors on June 10, 2016, Boenning informed the board that two (2) of the potential acquirers had decided not to continue in the process, leaving two finalists. At that same meeting, the board reviewed the remaining two (2) indications of interest in detail and provided Boenning with a list of requested changes to each indication of interest. Boenning contacted each party to review and discuss the board’s requested changes and provided each party a last opportunity to increase its bid.

At a telephonic special meeting of the board of directors on June 14, 2016, Liberty’s board of directors reviewed the two (2) final bid offers and reviewed the process that had resulted in an attractive price for Liberty. The board considered the value of each offer and the liquidity each one provided to its stockholders, while also evaluating the merits of remaining independent and growing Liberty organically or through acquisitions. The board also considered the quality of Middlefield’s operating performance as well as a relative valuation of Middlefield’s stock that appeared to be attractive for those Liberty stockholders electing to receive stock. The board determined that the updated oral offer from Middlefield was in the best interest of the stockholders and authorized management to execute the latest indication of interest from Middlefield. Specifically, Middlefield’s revised indication of interest provided for a price increase of approximately $0.55 per share of Liberty common stock and inclusion of two (2) current directors of Liberty (Messrs. Bevan and Valerian) on the Middlefield board of directors immediately following the closing of the transaction. Middlefield’s revised indication of interest also contemplated that, immediately prior to the consummation of the Merger, Liberty would distribute a $12.5 million special dividend to its stockholders.

The parties executed the revised indication of interest on June 14, 2016 and began preparation of the Reorganization Agreement. Subsequently, Liberty’s outside tax counsel reviewed Middlefield’s revised

indication of interest and, after consultation with and concurrence from Middlefield’s outside tax counsel, determined that the proposed payment by Liberty of a $12.5 million dividend to its stockholders immediately prior to completion of the Merger would adversely affect the tax-free reorganization treatment of the Merger and the ability of Liberty’s tax counsel to issue a favorable tax opinion. Following further discussions among the

parties and their counsel, it was determined that the transaction should be restructured to reduce the Liberty special dividend from $12.5 million to approximately $3.0 million, increase the cash portion of the Merger consideration from 50% to 55% and decrease the common shares portion of the Merger consideration to 45%, while maintaining the same total transaction value. Over the next several weeks, the parties revised the draft Reorganization Agreement to reflect the latest structure of the transaction and negotiated its terms and conditions.

At a meeting of the board of directors on July 27, 2016, the board of directors reviewed in detail the draft Reorganization Agreement and also received the opinion from Boenning that the proposed Merger consideration was fair to Liberty’s stockholders from a financial point of view. The board of directors authorized the execution of the Merger Agreement, and each member of the board of directors who owns Liberty common stock entered into a written agreement to vote all of the Liberty shares that he or she beneficially owns in favor of the approval of the transactions contemplated by the Reorganization Agreement.

Management of Liberty signed the Reorganization Agreement on behalf of Liberty as of July 28, 2016 on the terms approved by the board of directors.

The directors of Liberty believe that adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement are in the best interest of Liberty and its stockholders. Consequently, the directors unanimously recommend that Liberty stockholders adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. The directors of Liberty have agreed to vote their shares of Liberty common stock in favor of the Merger Proposal.

Boenning is acting as financial advisor to Liberty in connection with the proposed Merger. Boenning is a registered broker-dealer providing investment banking services with substantial expertise in transactions similar to the proposed Merger. As part of its investment banking activities, Boenning is regularly engaged in the valuation of businesses and securities in connection with mergers, acquisitions, underwritings, private placements and valuations for estate, corporate and other purposes.

On July 27, 2016, Boenning rendered its oral opinion, which was subsequently confirmed in writing, to the Liberty board of directors that, as of such date and subject to the assumptions made, matters considered and limitations of the review undertaken by Boenning, the Merger consideration to be received by the holders of Liberty’s common stock pursuant to the Reorganization Agreement was fair, from a financial point of view, to such holders.

The full text of Boenning’s written opinion dated July 27, 2016, which sets forth the assumptions made, matters considered and limitations of the review undertaken, is attached as Annex C to this proxy ~~statement and is incorporated herein by reference.~~statement. You are urged to, and should, read this opinion carefully and in its entirety in connection with this joint proxy ~~statement.~~statement/prospectus. The summary of Boenning’s opinion set forth in this joint proxy ~~statement~~statement/prospectus is qualified in its entirety by reference to the full text of the opinion. Boenning’s opinion speaks only as of the date of the opinion and does not reflect any developments that may occur or may have occurred after the date of its opinion and prior to the completion of the proposed Merger.

No limitations were imposed by Liberty on the scope of Boenning’s investigation or the procedures to be followed by Boenning in rendering its opinion. Boenning was not requested to, and did not, make any recommendation to the Liberty board of directors as to the form or amount of the consideration to be paid to the Liberty stockholders, which was determined through arm’s length negotiations between the parties. In arriving at its opinion, Boenning did not ascribe a specific range of values to Liberty. Its opinion is based on the financial and comparative analyses described below.

Boenning’s opinion was given in reliance on information and representations made or given by Middlefield, Liberty, and their respective officers, directors, auditors, counsel and other agents, and on filings, releases and other information issued by each of Middlefield and Liberty including financial statements, financial projections, and stock price data as well as certain information from recognized independent sources. Boenning did not independently verify the information concerning Middlefield or Liberty nor any other data Boenning considered in its review and, for purposes of its opinion, Boenning assumed and relied upon the accuracy and completeness of all such information and data. Boenning assumed that all forecasts and projections provided to it had been reasonably prepared and reflected the best currently available estimates and good faith judgments of the respective management teams of Middlefield and Liberty as to their most likely future financial performance. Boenning expressed no opinion as to any financial projections or the assumptions on which they were based. Boenning did not conduct any valuation or appraisal of any assets or liabilities of Middlefield or Liberty, nor have any such valuations or appraisals been provided to Boenning. Additionally, Boenning assumed that the proposed Merger is, in all respects, lawful under applicable law.

loans or credit files of Middlefield and Liberty. Boenning assumed that all of the representations and warranties contained in the reorganization Agreement and all related agreements were true and correct, that each party under the agreements will perform all of the covenants required to be performed by such party under the agreements, and that the conditions precedent in the agreements were not waived. Also, in rendering its opinion, Boenning assumed that in the course of obtaining the necessary regulatory approvals for the consummation of the proposed Merger no conditions will be imposed that will have a material adverse effect on the combined entity or contemplated benefits of the proposed Merger, including the cost savings and related expenses expected to result from the proposed Merger.

Boenning’s opinion is based upon information provided to it by the respective management teams of Middlefield and Liberty, as well as market, economic, financial and other conditions as they existed and could be evaluated only as of the date of its opinion and accordingly, it speaks to no other period. Boenning did not undertake to reaffirm or revise its opinion or otherwise comment on events occurring after the date of its opinion and did not have an obligation to update, revise or reaffirm its opinion. Boenning’s opinion does not address the relative merits of the proposed Merger or the other business strategies that Liberty’s board of directors has considered or may be considering, nor does it address the underlying business decision of Liberty’s board of directors to proceed with the proposed Merger. Boenning’s opinion is for the information of Liberty’s board of directors in connection with its evaluation of the proposed Merger and does not constitute a recommendation to the board of directors of Liberty in connection with the proposed Merger or a recommendation to any stockholder of Liberty as to how such stockholder should vote or act with respect to the proposed Merger.

In connection with rendering its opinion, Boenning performed a variety of financial analyses that are summarized below. This summary does not purport to be a complete description of such analyses. Boenning believes that its analyses and the summary set forth herein must be considered as a whole and that selecting portions of such analyses and the factors considered therein, without considering all factors and analyses, could create an incomplete view of the analyses and processes underlying its opinion. The preparation of a fairness opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Boenning considered the results of all of its analyses as a whole and did not attribute any particular weight to any analyses or factors considered by it. The range of valuations resulting from any particular analysis described below should not be taken to be Boenning’s view of the actual value of Liberty.

In its analyses, Boenning made numerous assumptions with respect to industry performance, business and economic conditions, and other matters, many of which are beyond the control of Liberty or Middlefield. Any estimates contained in Boenning’s analyses are not necessarily indicative of actual future values or results, which may be significantly more or less favorable than suggested by such estimates. Estimates of values of companies do not purport to be appraisals or necessarily reflect the actual prices at which companies or their securities actually may be sold. No company or transaction utilized in Boenning’s analyses was identical to Liberty or Middlefield or the proposed Merger. Accordingly, an analysis of the results described below is not mathematical; rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other facts that could affect the public trading value of the companies to which they are being compared. None of the analyses performed by Boenning was assigned a greater significance by Boenning than any other, nor does the order of analyses described represent relative importance or weight given to those analyses by Boenning. The analyses described below do not purport to be indicative of actual future results, or to reflect the prices at which Liberty’s common stock or Middlefield’s common stock may trade in the public markets, which may vary depending upon various factors, including changes in interest rates, dividend rates, market conditions, economic conditions and other factors that influence the price of securities.

In accordance with customary investment banking practice, Boenning employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses that Boenning used in providing its opinion on July 27, 2016. Some of the summaries of financial analyses are presented in tabular format. In order to understand the financial analyses used by Boenning more fully, you

should read the tables together with the text of each summary. The tables alone do not constitute a complete description of Boenning’s financial analyses, including the methodologies and assumptions underlying the analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by Boenning. The summary data set forth below do not represent and should not be viewed by anyone as constituting conclusions reached by Boenning with respect to any of the analyses performed by it in connection with its opinion. Rather, Boenning made its determination as to the fairness to the holders of Liberty’s common stock of the Merger consideration, from a financial point of view, on the basis of its experience and professional judgment after considering the results of all of the analyses performed. Accordingly, the data included in the summary tables and the corresponding imputed ranges of value for Liberty should be

considered as a whole and in the context of the full narrative description of all of the financial analyses set forth in the following pages, including the assumptions underlying these analyses. Considering the data included in the summary table without considering the full narrative description of all of the financial analyses, including the assumptions underlying these analyses, could create a misleading or incomplete view of the financial analyses performed by Boenning.

In connection with rendering its opinion and based upon the terms of the draft Agreement and Plan of Reorganization reviewed by it, Boenning assumed the effective aggregate indicated Merger consideration to be $41.57 million and the per share Merger consideration to be $42.14, based on Middlefield’s closing stock price on July 26, 2016, of $33.76.

Comparison of Selected Companies. Boenning reviewed and, as reflected in Table 1 below, compared the multiples and ratios of the offer price to Liberty’s book value, tangible book value, latest 12 months earnings per share, assets, tangible book premium to core deposits, and deposits, such multiples referred to herein as the pricing multiples, with the median pricing multiples for the current trading prices, after the application of a 29.7% assumed control premium, referred to as the adjusted trading price, of the common stock of a peer group of 22 selected public banks and thrifts with assets between $150 million and $400 million, tangible common equity / tangible assets between 11% and 15% and latest 12 months return on average tangible common equity between 5% and 8.5%, excluding merger targets. The 29.7% equity control premium is the median one day stock price premium for all bank and thrift merger and acquisition deals announced since January 1, 2000, based on data from SNL Financial.

Analysis of Bank Merger Transactions. Boenning analyzed certain information relating to recent transactions in the banking industry, consisting of (i) nine Midwest bank and thrift transactions announced since January 1, 2014 with target assets between $100 million and $600 million, tangible equity / tangible assets between 11% and 17%, latest 12 months return on average equity between 5% and 10%, and disclosed pricing, referred to below as Group A; and (ii) 17 nationwide bank and thrift deals announced since January 1, 2014 with target assets between $150 million and $400 million, tangible equity / tangible assets between 12% and 18%,

latest 12 months return on average equity between 2% and 12%, and disclosed pricing, referred to below as Group B. As reflected in Table 2 below, Boenning then reviewed and compared the pricing multiples of the offer price and the median pricing multiples of the selected transaction values for Group A and Group B.

Discounted Cash Flow Analysis. Discounted cash flow analysis approximates the value of a share of stock to an acquiror by calculating the present value of the target’s dividendable cash flow in perpetuity. This analysis assumed a short-term earnings growth rate of 5% and a long-term growth rate of 2%, as well as a short-term balance sheet growth rate of 3.5% and a long-term growth rate of 2%, based on guidance from Liberty’s management. The estimated cost savings of 30% in year one, 35% in year two and 40% thereafter, transaction costs of $3.1 million pre-tax and gross credit mark of approximately $5.1 million, or 2.75% of loans (equal to $1.8 million net of Liberty’s loan loss reserve) were based on guidance provided by Middlefield. A discount rate of 13% was determined using the Capital Asset Pricing Model and the Build-Up Method, both of which take into account certain factors such as the current risk free rate, the beta of bank stocks compared to the broader market and the Ibbotson risk premiums for small, illiquid stocks and for commercial bank stocks, as well as comparable company returns on tangible common equity. The average of the three methods was approximately 13%. Sensitivity analyses for discount rates and cost savings ranged from 11% to 15% and 33.5% to 46.5%, respectively. The present value of Liberty common stock calculated using discounted cash flow analysis ranged from $34.50 per share to $55.26 per share based on the cost savings estimates and discount rates used, compared to the offer price of $42.14 per share. This analysis does not purport to be indicative of actual future results and does not purport to reflect the prices at which shares of Liberty common stock may trade in the public markets. A discounted cash flow analysis was included because it is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, including earnings growth rates, dividend payout rates and discount rates.

Present Value Analysis. Applying present value analysis to Liberty’s theoretical future earnings, dividends and tangible book value, Boenning compared the offer price for one share of Liberty’s common stock to the present value of one share of Liberty’s common stock on a stand-alone basis. The analysis was based upon management’s projected earnings growth, a range of assumed price/earnings ratios, a range of assumed price/tangible book value ratios and a 13% discount rate, which was determined using the Capital Asset Pricing Model and the Build-Up Method, both of which take into account certain factors such as the current risk free rate, the beta of bank stocks compared to the broader market and the Ibbotson risk premiums for small, illiquid stocks and for commercial bank stocks, as well as comparable company returns on tangible common equity. The average of the three methods was approximately 13%. The valuation was completed with a sensitivity analysis on the discount rate ranging from 11% to 15%. Boenning derived the terminal price/earnings multiple of 15.8x and terminal price/tangible book value multiple of 123.7% from the three-year median trading multiples of the SNL Bank < $500 Million Index as of July 26, 2016. Sensitivity analyses for terminal price/earnings and price/tangible book ranged from 11.4x to 20.2x and 103.4% to 144.0%, respectively. The present value of Liberty’s common stock on a standalone basis is $22.86 to $45.10 per share based on price/earnings multiples, and $22.55 to $40.65 per share based on price/tangible book value multiples, compared to the offer price of $42.14 per share. This analysis does not purport to be indicative of actual future results and does not purport to reflect the

prices at which shares of Liberty’s common stock may trade in the public markets. A present value analysis was included because it is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, including earnings growth rates, dividend payout rates and discount rates.

Pro Forma Merger Analysis. Boenning analyzed certain potential pro forma effects of the Merger, assuming the following: (i) the proposed Merger is completed December 31, 2016; (ii) each share of Liberty’s common stock will be eligible to receive consideration of approximately $42.14 consisting of a $3.13 special cash dividend, $20.88 in cash, and $17.09 in Middlefield stock; (iii) estimated pre-tax cost savings of approximately 40% of Liberty’s ~~non-interest~~noninterest expense on an annual basis, recognized 75% in 2017 and 87.5% in 2018; (iv) estimated one-time transaction-related costs of approximately $3.5 million pre-tax are expensed prior to closing; (v) Liberty performance was calculated in accordance with Liberty management’s earnings forecasts; (vi) Middlefield’s performance was calculated in accordance with Middlefield management’s earnings forecasts; and (vii) certain other assumptions pertaining to costs and expenses associated with the transaction, intangible amortization, opportunity cost of cash and other items. The analyses indicated that, for the full years 2017 and 2018, the proposed Merger (excluding transaction expenses) would be accretive to the combined company’s projected earnings per share and accretive to Liberty’s per share equivalent earnings, tangible book value and dividends. Additionally, the combined company’s regulatory capital ratios would exceed regulatory guidelines for “well capitalized.” The actual results achieved by the combined company may vary from projected results and the variations may be material.

As described above, Boenning’s opinion was just one of the many factors taken into consideration by the Liberty board of directors in making its determination to approve the proposed Merger.

Boenning, as part of its investment banking business, regularly is engaged in the valuation of assets, securities and companies in connection with various types of asset and security transactions, including mergers, acquisitions, private placements, public offerings and valuations for various other purposes, and in the determination of adequate consideration in such transactions. In the ordinary course of Boenning’s business as a broker-dealer, it may, from time to time, purchase securities from, and sell securities to, Middlefield, Liberty, and/or their respective affiliates. In the ordinary course of business, Boenning may also actively trade the securities of Middlefield and Liberty for its own account and/or for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

Boenning is acting as Liberty’s financial advisor in connection with the proposed Merger and will receive a customary fee for its services, a significant portion of which is contingent upon consummation of the Proposed Merger. Boenning also received a fee for rendering the fairness opinion. Boenning’s fee for rendering the fairness opinion was not contingent upon any conclusion that Boenning reached or upon completion of the proposed Merger. The Company has also agreed to indemnify Boenning against certain liabilities that may arise out of Boenning’s engagement.

Prior Engagements by Middlefield and Liberty. Boenning was engaged in February 2016 by Middlefield to serve as placement agent for a private placement of common stock. The offering ultimately closed on June 30, 2016, and Boenning was paid a commission for its role. Boenning advised, and received compensation from, Liberty in 2014 relating to the exploration of strategic alternatives, although no transaction was consummated at that time.

Except for the arrangements between Boenning and Liberty and Middlefield described in the preceding paragraphs, Boenning has not had any material relationship with either Middlefield or Liberty during the past two years in which compensation was received or was intended to be received. Boenning may provide services to Middlefield in the future (and/or to Liberty if the proposed Merger is not consummated), although as of the date of Boenning’s opinion, there was no agreement to do so nor any mutual understanding that such services are contemplated.

Boenning’s opinion was approved by Boenning’s fairness opinion committee. Boenning did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the proposed Merger by any of the officers, directors, or employees of any party to the reorganization Agreement, or any class of such persons, relative to the compensation to be received by the holders of Liberty’s common stock in the proposed Merger.

For a number of reasons, including the unpredictability of underlying assumptions and estimates, Liberty does not routinely publicly disclose forecasts or internal projections of future performance, earnings, or other results. However, Boenning ~~& Scattergood, Inc. used~~considered financial projections provided by or reviewed with senior management of Liberty for the purpose of preparing the financial analyses supporting ~~Boenning & Scattergood’s~~Boenning’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Liberty’s Financial Advisor.” In addition, Donnelly Penman & Partners Inc. ~~used~~considered internal financial projections provided by and/or reviewed with senior management of Liberty for the purpose of preparing the financial analyses supporting Donnelly Penman’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Middlefield’s Financial Advisor.” A summary of these projections is therefore included in this joint proxy statement/prospectus because the projections were ~~used~~considered by Boenning and by Donnelly ~~Penman.~~Penman in preparing their analyses.

When the financial projections were prepared, they represented the best estimates and judgments of Liberty management about future financial performance. The financial projections summarized below were prepared in good faith, but financial projections are subjective in many respects and are susceptible to interpretation and periodic revision based on actual experience and recent developments. Accordingly, financial projections do not reliably predict future operating results. The financial projections were not prepared with the expectation of public disclosure or with the goal of complying with American Institute of Certified Public Accountants guidelines for prospective financial information or SEC guidelines regarding forward-looking statements. Although presented with numeric specificity, the financial projections reflect numerous estimates and assumptions that might not be realized and are subject to significant uncertainties and contingencies, many of which are beyond Liberty’s control. For these reasons and because of the uncertainties inherent in financial projections, Liberty stockholders and Middlefield stockholders should not unduly rely on these financial projections as predictions of future operating results.

The financial projections of Liberty included in this joint proxy statement/prospectus were prepared by and are the responsibility of Liberty management. Neither Liberty’s independent registered public accounting firm nor any other independent accounting firm examined, compiled, or performed any procedures on these financial projections, and therefore express no opinion or any other form of assurance regarding the financial projections. Inclusion of the financial projections in this joint proxy statement/prospectus is not an admission or representation by Liberty or Middlefield that Liberty or Middlefield consider the financial projections to be material information.

All of the financial projections are forward-looking statements. The estimates and assumptions underlying the financial projections summarized below involve judgments regarding future economic, competitive, regulatory, and financial market conditions and future business decisions. The estimates and assumptions may not be realized and are inherently subject to significant business, economic, competitive, and regulatory uncertainties, all of which are difficult to predict and many of which are beyond Liberty’s control. In addition, these financial projections represent Liberty’s evaluation at the time the projections were prepared of its future financial performance on a stand-alone basis, and without reference to the proposed Merger or transaction-related costs or benefits. Accordingly, Liberty gives no assurance that the projected results will be realized or that actual results will not differ materially from those presented in the financial projections. Inclusion of these financial projections should not be interpreted as a statement that Liberty or Middlefield considers this information a reliable prediction of future results, or that the projections would be the same if prepared by Liberty as of the date of this document, and this information should not be unduly relied on for that purpose.

Liberty provided to Boenning and Donnelly Penman the following estimate of per share earnings on a stand-alone basis for the period 2017 through ~~2022,~~2020, based on its internal strategic plan for 2016-2018 and forward growth expectations for 2019 and beyond:

Middlefield’s board of directors believes the Merger is in the best interests of Middlefield and its stockholders and therefore unanimously approved the transactions contemplated by the Reorganization Agreement and the Merger. The board reached this decision after consulting with management and with Middlefield’s financial and legal advisors. The board’s reasoning was based on many factors, including but not limited to the following:

Middlefield’s board of directors considered many factors in its evaluation. The board did not quantify or assign relative weights to any individual factors in its decision.

Middlefield’s board of directors unanimously approved the transactions contemplated by the Reorganization Agreement and the issuance of common stock in the Merger. The board believes the Merger and the common stock issuance are in the best interests of Middlefield and its stockholders. Accordingly, the directors unanimously recommend that Middlefield stockholders vote “FOR” adoption and approval of the Reorganization Agreement and“FOR” issuance of common stock in the Merger.

On April 19, 2016 Middlefield’s board of directors retained Donnelly Penman to provide merger advisory services. As part of the engagement, Donnelly Penman was asked to assess the fairness to Middlefield stockholders, from a financial point of view, of the approximately $40.0 million consideration being paid.

Donnelly Penman is a regional investment banking firm headquartered in Grosse Point, Michigan. Donnelly Penman is continually engaged in the valuation of businesses and securities in mergers and acquisitions, in secondary distributions of securities, and in private placements, as well as valuations for going-private transactions, corporate, and other purposes.

Donnelly Penman representatives attended the July 27, 2016 meeting at which Middlefield’s board of directors evaluated and ultimately approved the Reorganization Agreement and proposed Merger. At this meeting Donnelly Penman reviewed the financial aspects of the proposed transaction and rendered an opinion that as of such date the approximately $40.0 million consideration being paid, including the cash and stock consideration payable to Liberty stockholders in exchange for their Liberty common stock, the approximately $3.0 million special dividend to be declared by Liberty before closing, and the ~~approximately $1.1 million~~cash payable in cancellation of Liberty’s outstanding options and phantom stock, was fair from a financial point of view to Middlefield stockholders.

The full text of Donnelly Penman’s written opinion is attached as Annex D to this joint proxy statement/prospectus. The following summary of the opinion is qualified in its entirety by reference to the full text of the opinion in Annex D. You should read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Donnelly Penman. Donnelly Penman’s opinion is necessarily based upon economic and market conditions and other circumstances as they existed and were evaluated on the date of the opinion.

Donnelly Penman’s opinion speaks only as of the date of the opinion. The opinion is directed to Middlefield’s Board of Directors and addresses only the fairness to Middlefield stockholders, from a financial point of view, of the consideration being paid. It does not address the underlying business decision to proceed with the Merger and does not constitute a recommendation to any stockholder about how the stockholder should vote regarding the Merger.

Donnelly Penman discussed current business operations, financial conditions and prospects of Middlefield and Liberty the management teams of Middlefield and Liberty, in addition to discussions with independent directors of Middlefield. The resources Donnelly Penman reviewed in the process of forming its fairness opinion also include but are not limited to the following:

Donnelly Penman also discussed with Middlefield management past and current business operations, regulatory relations, financial condition, future prospects, and other matters. Donnelly Penman also discussed with Liberty management that bank’s business operations, regulatory relations, earnings results, and future prospects.

Donnelly Penman relied upon the accuracy and completeness of all financial and other information provided to it or publicly available, and did not assume responsibility for the accuracy, completeness, or reasonableness of or responsibility for verification of the information. Donnelly Penman did not make any independent evaluations, valuations, or appraisals of the assets or liabilities of Middlefield or Liberty, did not review individual credit files, and assumed that the aggregate allowances for credit losses relating to the loans of Middlefield and Liberty are and will continue to be adequate to cover losses. Donnelly Penman relied upon Middlefield management regarding the reasonableness and achievability of the financial and operating forecasts and projections (and the

assumptions and bases therefor) prepared by and provided by Middlefield management, and similarly relied on Liberty management regarding the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefor) prepared by and provided by Liberty management. Donnelly Penman assumed that the forecasts and projections of Middlefield management reflect management’s best

currently available estimates and judgments and that the forecasts and projections will be realized in the amounts and in the time periods estimated and that they provide a reasonable basis for Donnelly Penman’s opinion. Likewise, Donnelly Penman assumed that the forecasts and projections of Liberty management reflect Liberty management’s best currently available estimates and judgments and that the forecasts and projections will be realized in the amounts and in the time periods estimated and that they provide a reasonable basis for Donnelly Penman’s opinion. The Middlefield and Liberty forecasts and projections were not prepared with the expectation of public disclosure. The projected financial information is based on numerous variables and assumptions that are inherently uncertain, including without limitation factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from projected results. Donnelly Penman relied on the projected information without independent verification or analysis. Donnelly Penman relied upon the assurance of Middlefield management and Liberty management that they were unaware of any facts that would make the information provided or available to Donnelly Penman incomplete or misleading.

The following is a summary of the material analyses presented by Donnelly Penman to the Middlefield’s board of directors on July 27, 2016. The Donnelly Penman opinion was not the only factor taken into consideration by Middlefield’s board of directors in the board’s decision to approve the Reorganization Agreement and the Merger. Consequently, the analyses described below were not determinative in the board’s decision. The summary is not a complete description of the analyses underlying the Donnelly Penman opinion or the presentation made by Donnelly Penman to Middlefield’s board of directors, but summarizes the material analyses performed and presented. The preparation of a fairness opinion is a complex analytic process. Donnelly Penman did not attribute any particular weight to any analysis or factor it considered, but rather made qualitative judgments about the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. Accordingly, Donnelly Penman believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion.

The summary of Donnelly Penman’s analyses to follow includes a summary of its analysis of comparable transactions, analysis of a dividend discount model on a stand-alone basis for Middlefield (stand-alone meaning without taking the Merger into account) and on a pro forma, post-merger basis, analysis of tangible book value dilution and earnings accretion attributable to the Merger, analysis of comparable public companies to Middlefield on a stand-alone basis and pro forma basis, and finally a contribution analysis that considers the anticipated 18.7% pro forma outstanding shares of Middlefield common stock held by Liberty stockholders relative to the percentage contribution of Liberty assets, loans, deposits, and tangible common equity to the pro forma combined entity. Donnelly Penman made numerous assumptions regarding industry performance, business and economic conditions, and other matters, many of which are beyond the control of Middlefield and Liberty. Credit, financial, and stock markets can experience unusual volatility. No company or merger included in Donnelly Penman’s analysis is identical to Middlefield or Liberty and the comparable transactions considered by Donnelly Penman are not identical to the proposed Merger. Accordingly, Donnelly Penman’s analyses are not based solely on arithmetic calculations but instead involve complex considerations and judgments concerning differences in financial and operating characteristics of the relevant companies, the timing of the relevant mergers and prospective buyer interests, as well as other factors that could affect the public trading markets of companies to which Middlefield is being compared. None of the analyses performed by Donnelly Penman was assigned a greater significance than any other.

Comparable Transaction Analysis.Donnelly Penman reviewed publicly available information related to comparable acquisitions of banks and bank holding companies as well as thrifts and thrift holding companies. The selection criteria were (1) transaction announcement after June 30, 2014, (2) total assets of acquired company between $100 and $300 million, (3) last twelve month (LTM) return on average assets (ROAA) of acquired company between 0.75% and 1.00%, and (4) nonperforming assets as a percent of total assets of acquired company less than 3.0%. Based on these criteria, Donnelly Penman identified 22 comparable acquisition transactions on a national level –

Donnelly Penman considered the transaction price per share as a percent of the acquired company’s June 30, 2016 book value, as a percent of the acquired company’s tangible book value as of that date, as a multiple of the acquired company’s LTM earnings per share in the twelve-month period ended June 30, 2016, and as a percent of the acquired company’s June 30, 2016 core deposits, which generally consist of total deposits other than time deposits exceeding $100,000. For comparison purposes, Donnelly Penman calculated the total transaction price to be $40.6 million, or $42.28 per share, which is derived from an estimated $16,387,359 stock consideration to be issued in the Merger in exchange for 45% of Liberty’s 959,283 outstanding shares and an estimated $23,027,910 cash consideration. The cash component includes not only cash Merger consideration payable in exchange for Liberty common stock but also the $3.0 million special dividend and the approximately $1.1 million payable for cancellation of outstanding shares and phantom stock. As a percent of book value, tangible book value, LTM earnings per share, and core deposits, the $42.28 per share price is –

Of the 22 comparable acquisition transactions on a national level, nine are transactions of companies in the greater Midwest –

As a percent of book value, tangible book value, LTM earnings per share, and core deposits for this regional group, the $42.28 per share price is –

None of the companies or 22 transactions used as a comparison in these analyses is identical to Liberty, Middlefield, or the Merger. Analysis of these results is not solely mathematical, but instead involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies.

Dividend Discount Model Analysis. Donnelly Penman performed a discounted cash flow analysis of Middlefield on a stand-alone basis and on a pro forma, post-merger basis, estimating the value of a share of Middlefield common stock to be $34.56 on a stand-alone basis and $45.14 pro forma. These estimated values are the sum of two estimated values discounted back to the hypothetical December 31, 2016 merger date: (x) cash dividends for the five year period 2016 through 2020 and (y) residual or terminal value at the end of the five-year period. To determine present value, Donnelly Penman used a 13.00% discount rate.

Donnelly Penman’s estimate assumes Middlefield’s dividend remains constant at $1.08 annually both on a stand-alone basis and pro forma, post-merger. The per share values also assume Middlefield’s outstanding shares increase by 20,000 annually through Middlefield’s dividend reinvestment plan, with pro forma outstanding shares including the estimated 515,164 shares issuable to Liberty stockholders in the Merger. At a 13.00% discount rate, the present value of the five-year projected cash dividend income is $3.56 on a stand-alone and pro forma basis. For the estimated total $34.56 value of Middlefield on a stand-alone basis and $45.14 estimated pro forma value, the residual or terminal value at the end of the five-year period is derived by taking the average of a multiple of 1.40 times projected book value at the end of 2020 and 15.0 times projected 2020 net income, discounting that average value back to the December 31, 2016 hypothetical merger date at 13.0%. To derive the estimated stand-alone value, Donnelly Penman used Middlefield management’s forecasted figures for 2016 through 2018, extrapolating from that at 8.00% annual growth for the years 2019 and 2020. Likewise, to derive the estimated pro forma, post-merger value Donnelly Penman used Middlefield management’s and Liberty management’s forecasts for 2016 through 2018, extrapolating at 8.00% annual growth for the years 2019 and 2020. Net income assumes Middlefield’s effective tax rate is 22%. Because the projected allowance for loan losses at the end of 2018 is projected to exceed 1.25%, the pro forma estimate assumes no additional provision expense attributable to Liberty in the years 2017 and 2018, but earnings are based on a slower growth rate

thereafter to anticipate provision expense in 2019 and 2020. For purposes of the pro forma estimate, Middlefield management estimates a 30% reduction of Liberty’s noninterest expense in 2017 and 35% thereafter.

Discounted cash flow present value analysis is a widely used valuation methodology, but it relies on numerous assumptions and estimates, including but not limited to asset and earnings growth rates, discount rates, and multiples of earnings or book value or both to derive residual or terminal values. The numeric per share result of the analysis is not the stock’s actual value or expected value. It is merely an estimate within a broad range of potential value estimates.

Tangible Book Value Dilution and Earnings Accretion. Donnelly Penman estimates that Middlefield’s tangible book value per share at December 31, 2016 would be $33.52 without taking the Merger into account, with 16.3% dilution, or $5.46 dilution per share, on a pro forma, post-merger basis at December 31, 2016. The Middlefield Banking Company’s pro forma Tier 1 leverage ratio would be 7.71%, with pro forma Total Risk-Based Capital of 10.89% and pro forma Tangible Common Equity as a percent of tangible assets at 8.32%. Donnelly Penman estimates that the dilution of tangible book value could be eliminated, or earned back, in a period ranging from three to four years, which is consistent with the 3.9 year median period to earn back tangible book value dilution in a group of nine recent acquisitions examined by Donnelly Penman. Those nine transactions were announced between July 2, 2013 and June 2, 2016, with the first three transactions not yet completed on the date of Donnelly Penman’s analysis in July 2016. The nine transactions involve acquired companies in Ohio, Indiana, Pennsylvania, and Michigan, with total deal values ranging from $30 million to $50 million –

Comparable Public Company Analysis. Donnelly Penman also analyzed a group of 20 publicly traded companies Donnelly Penman considers comparable to Middlefield on a stand-alone basis because of location, asset size, and return on average assets (ROAA). The companies are all located in the Midwest or the greater Midwest region, have total assets between $500 million and $1.0 billion, and have an ROAA between 0.75% and 1.25%. Taking their stock price as of July 22, 2016 and using publicly available data, Donnelly Penman determined that the companies’ price to book value, price to tangible book value, and price to LTM EPS (as of June 30, 2016) are –

Donnelly Penman identified a similar group of 18 publicly traded companies that Donnelly Penman considers comparable to Middlefield on a pro forma, post-merger basis, based on an asset size range of $800 million to $1.5 billion, again limited to companies located in the greater Midwest and with ROAA between 0.75% and 1.25%. Taking their stock price as of July 22, 2016 and using publicly available data, Donnelly Penman determined that the companies’ price to book value, price to tangible book value, and price to LTM EPS (as of June 30, 2016) are –

The 18 companies matching Donnelly Penman’s criteria for companies comparable to Middlefield on a pro forma basis are –

Contribution Analysis. Assuming there are 515,164 shares of Middlefield common stock issued in the Merger to Liberty stockholders, Liberty stockholders will possess 18.7% of total pro forma shares outstanding but will contribute an average of 23.9% to the combined entity in terms of the entity’s total assets, total loans, total deposits, and tangible common equity as of June 30, 2016, and 2015 net income and last twelve months (as of June 30, 2016) net income –

The contribution analysis assumes there are 2,762,068 shares outstanding after the Merger. Accounting adjustments under ASC 805 (formerly FAS 141R) are not taken into account.

Relationships. Donnelly Penman & Partners acted exclusively for the Middlefield board of directors in rendering the opinion included as Annex D to this joint proxy statement/prospectus. Donnelly Penman will receive a fee from Middlefield for its services. Donnelly Penman has also acted as Middlefield’s advisor for the Merger transaction, and a portion of Donnelly Penman’s fee is contingent on the Merger’s successful completion. Middlefield agreed to pay Donnelly Penman a $40,000 fee for the fairness opinion, agreeing to pay an additional $5,000 for each fairness opinion update. Additionally, Middlefield paid Donnelly Penman an initial advisory fee of $12,500 at execution of the April 19, 2016 engagement letter agreement and an additional advisory fee of $12,500 after Liberty identified Middlefield as one of the bidders invited to submit final bids. The advisory fees will be credited against the success fee payable to Donnelly Penman at Merger closing. The total success fee is $250,000, including a nonrefundable $75,000 portion that Middlefield paid when the Reorganization Agreement was signed. Donnelly Penman will receive the remaining portion of the success fee when the Merger is completed ($150,000, after crediting of the advisory fees). Middlefield agreed to reimburse Donnelly Penman for up to $7,500 of reasonable and customary out-of-pocket expenses and disbursements, also agreeing to indemnify Donnelly Penman against liabilities incurred for its services. The initial term of the engagement agreement ends December 31, 2016.

Donnelly Penman has provided advisory services to Middlefield in the past, including a March 2015 engagement concerning a potential acquisition, which did not lead to an acquisition transaction but for which Middlefield paid Donnelly Penman a retainer fee, and an October 2015 engagement concerning another potential acquisition, which also did not lead to an acquisition transaction but for which Middlefield paid Donnelly Penman a retainer. Donnelly Penman has never been engaged by Liberty for any purpose.

Nonpublic Financial Projections Provided to Middlefield’s Financial Advisor

For a number of reasons, including the unpredictability of underlying assumptions and estimates, Middlefield does not routinely publicly disclose forecasts or internal projections of future performance, earnings, or other results. However, Donnelly Penman & Partners Inc. used financial projections provided by or reviewed with senior management of Middlefield for the purpose of preparing the financial analyses supporting Donnelly Penman’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Middlefield’s Financial Advisor.” A summary of these projections is included in this joint proxy statement/prospectus because the projections were used by Donnelly Penman.

When the financial projections were prepared, they represented the best estimates and judgments of Middlefield management about future financial performance. The financial projections summarized below were prepared in good faith, but financial projections are subjective in many respects and are susceptible to interpretation and periodic revision based on actual experience and recent developments. Accordingly, financial projections do not reliably predict future operating results. The financial projections were not prepared with the expectation of public disclosure or with the goal of complying with American Institute of Certified Public Accountants guidelines for prospective financial information or SEC guidelines regarding forward-looking statements. Although presented with numeric specificity, the financial projections reflect numerous estimates and assumptions that might not be realized and are subject to significant uncertainties and contingencies, many of which are beyond the control of Middlefield. For these reasons and because of the uncertainties inherent in financial projections, Liberty stockholders and Middlefield stockholders should not unduly rely on these financial projections as predictions of future operating results.

The financial projections of Middlefield included in this joint proxy statement/prospectus were prepared by and are the responsibility of Middlefield management. Neither Middlefield’s independent registered public accounting firm nor any other independent accounting firm examined, compiled, or performed any procedures on these financial projections, and therefore express no opinion or any other form of assurance regarding the financial projections. Inclusion of the financial projections in this joint proxy statement/prospectus is not an admission or representation by Liberty or Middlefield that Liberty or Middlefield consider the financial projections to be material information.

All of the financial projections are forward-looking statements. The estimates and assumptions underlying the financial projections summarized below involve judgments regarding future economic, competitive, regulatory, and financial market conditions and future business decisions. The estimates and assumptions might not be realized and are inherently subject to significant business, economic, competitive, and regulatory uncertainties, all of which are difficult to predict and many of which are beyond the control of Middlefield. In addition, these financial projections represent Middlefield’s evaluation at the time the projections were prepared of its future financial performance on a stand-alone basis, and without reference to the proposed merger or transaction-related costs or benefits. Accordingly, Middlefield gives no assurance that the projected results will be realized or that actual results will not differ materially from those presented in the financial projections. Inclusion of these financial projections should not be interpreted as a statement that Liberty or Middlefield considers this information a reliable prediction of future results, or that the projections would be the same if prepared by Middlefield as of the date of this document, and this information should not be unduly relied on for that purpose.

Middlefield provided to Donnelly Penman & Partners Inc. the following estimate of per share earnings for the period 2017 through ~~2022,~~2020, both for Middlefield on a stand-alone basis and on a pro forma, post-merger basis:

The Merger cannot be completed unless Middlefield and Liberty obtain regulatory approval. The Merger consists of two separate mergers: first a merger of Middlefield’s newly formed interim bank subsidiary into Liberty, followed immediately by the merger of Liberty into The Middlefield Banking Company. Accordingly, the Merger must be approved by the Office of the ~~Comptroller of the Currency (OCC),~~OCC, Liberty’s principal federal regulator, and by the FDIC, The Middlefield Banking Company’s principal federal regulator. The Ohio Division of Financial Institutions (ODFI) also has jurisdiction over the Merger, which is a third required regulatory approval of the Merger itself. Declaration by Liberty of the special dividend before closing is an integral part of

carried out under the Reorganization Agreement, but that special dividend cannot be paid unless Liberty first obtains OCC approval. Similarly, The Middlefield Banking Company and Middlefield must obtain ODFI approval of the approximately $9.0 million dividend to be paid by The Middlefield Banking Company to Middlefield, which is one of Middlefield’s sources of funds for the cash portion of the Merger consideration. The other source is borrowing of approximately ~~$11.7~~$12 million. Finally, Middlefield also must obtain approval from the ODFI for formation of the interim bank subsidiary and approval from the FDIC of deposit insurance for the interim bank subsidiary. All of these regulatory approvals are Merger closing conditions. ~~All necessary applications have been submitted. No approvals have been obtained. Although~~By letter dated November 7, 2016 the OCC approved the merger application, subject to the condition that the merger be completed within six months. In an October 24, 2016 letter the OCC also approved Liberty Bank’s $3.0 million special dividend. By letter dated October 31, 2016 the FDIC also approved the merger application, also subject to the merger being completed within six months. In a separate October 31, 2016 letter the FDIC also approved the deposit insurance application of MBC Interim Bank, for the sole purpose of enabling MBC Interim Bank to merge into Liberty Bank. Middlefield anticipates that the ODFI will approve both the merger application and the special dividend payable by The Middlefield believe approvals will be obtained, neither Liberty nor Middlefield can assure you when or whether the approvals will be obtained, or if obtained what approval conditions might be imposed. Middlefield is also seeking from the BoardBanking Company, as well as formation of ~~Governors of the Federal Reserve System waiver of the obligation to file an application under the Bank Holding Company Act of 1956.~~MBC Interim Bank.

Approval of a regulatory application merely implies satisfaction of regulatory criteria for approval, which does not include review of the adequacy or fairness of the Merger consideration to Liberty stockholders or Middlefield stockholders. Regulatory approvals do not constitute or imply any endorsement or recommendation of the Merger or the terms of the Reorganization Agreement.

Interests of Liberty’s Directors and Certain Executive Officers in the Merger

Officers and directors of Liberty have employment and other compensation agreements or economic interests that give them interests in the Merger that are somewhat different from or in addition to their interests as Liberty stockholders. These interests and agreements include –

At Liberty’s request, when Middlefield’s board approved the Reorganization Agreement it also approved the potential issuance to Liberty CEO William A. Valerian and Liberty Director Thomas W. Bevan of Middlefield common stock in the Merger. This has the effect of exempting from the application of short-swing trading principles under section 16(b) of the ~~Securities Exchange~~ Act ~~of 1934~~ their acquisition of Middlefield common stock in the Merger. Directors of an issuer that has equity securities registered under the Securities Exchange Act of 1934 are subject to short-swing trading restrictions. Messrs. Valerian and Bevan will be Middlefield directors after the Merger.

Each of Middlefield’s and Liberty’s board of directors was aware of these interests and considered them in approving the Reorganization Agreement and the transactions contemplated therein.

The following summary reflects the opinion of Tucker Ellis LLP, legal counsel to Liberty, with respect to the material U.S. federal income tax consequences of the Merger to U.S. holders (as defined below) of Liberty common stock. The summary is based upon the Internal Revenue Code, applicable Treasury Regulations, judicial decisions and administrative rulings and practice, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. This summary does not address any tax consequences of the Merger under state, local or foreign laws, or any federal laws other than those pertaining to income tax.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner that is: an individual citizen or resident of the United States; a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions; a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person; or an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion addresses only those U.S. holders of Liberty common stock that hold their Liberty common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code and does not address all the U.S. federal income tax consequences that may be relevant to particular holders of Liberty common stock in light of their individual circumstances or to holders of Liberty common stock that are subject to special rules, such as non-U.S. holders (as defined below) (except to the extent discussed under the subheading “Tax Implications to Non-U.S. Stockholders” below); financial institutions; investors in pass-through entities; persons who are subject to alternative minimum tax; insurance companies; mutual funds; tax-exempt organizations; dealers in securities or currencies; traders in securities that elect to use a mark-to-market method of accounting; persons that hold Liberty common stock as part of a straddle, hedge, constructive sale or conversion or other integrated transaction; regulated investment companies; real estate investment trusts; persons whose “functional currency” is not the U.S. dollar; and holders who acquired their shares of Liberty common stock through the exercise of an employee stock option or otherwise as compensation.

If a partnership (or other entity that is taxed as a partnership for federal income tax purposes) holds Liberty common stock, the tax treatment of a partner in that partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in partnerships should consult their own tax advisors about the tax consequences of the Merger to them.

Tucker Ellis LLP has delivered a legal opinion, dated September 26, 2016, and filed as an exhibit to the registration statement of which this joint proxy statement/prospectus is a part, to the effect that, subject to the

exceptions, qualifications and limitations set forth therein, (i) the Merger will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and (ii) Liberty and Middlefield will each be a party to such reorganization within the meaning of Section 368(a) of the Internal Revenue Code. Additionally, it is a condition to Liberty’s obligation to complete the Merger that Liberty receive an opinion from Tucker Ellis LLP, dated the closing date of the Merger, to that effect. [This condition is waivable, and Middlefield and Liberty

undertake to recirculate and resolicit if this condition is waived and the change in tax consequences is material.] This opinion is and will be based upon representation letters provided by Middlefield and Liberty and upon customary factual assumptions. Neither Middlefield nor Liberty has sought, and neither of them will seek, any ruling from the Internal Revenue Service regarding any matters relating to the Reorganization Agreement, and the opinion described above will not be binding on the Internal Revenue Service or any court. Consequently, there can be no assurance that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which the opinion is based are inconsistent with the actual facts, the U.S. federal income tax consequences of the Merger could be adversely affected. The actual tax consequences to you of the Merger may be complex and will depend upon your specific situation and upon factors that are not within the control of Middlefield or Liberty. You should consult with your own tax advisor as to the tax consequences of the Merger in light of your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws.

The following discussion summarizes the material U.S. federal income tax consequences of the Merger to U.S. holders.

Tax Consequences of the Merger for U.S. holders of Liberty Common Stock. The U.S. federal income tax consequences of the Merger to a U.S. holder will depend on whether such U.S. holder receives cash, shares of Middlefield common stock or a combination of cash and stock in exchange for such U.S. holder’s Liberty common stock. At the time a Liberty stockholder makes a cash or stock election pursuant to the terms of the Reorganization Agreement, such stockholder will not know whether, and to what extent, the proration provisions of the Reorganization Agreement will alter the mix of consideration such stockholder will receive. As a result, the tax consequences to such stockholder will not be ascertainable with certainty until such stockholder knows the precise amount of cash and shares of Middlefield common stock that such stockholder will receive pursuant to the Merger.

Exchange of Liberty common stock solely for Middlefield common stock. Except as discussed below, see “-“-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” a U.S. holder that exchanges all of its shares of Liberty common stock solely for shares of Middlefield common stock pursuant to the Merger will not recognize gain or loss in connection with such exchange. A U.S. holder’s aggregate tax basis in the Middlefield common stock received in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will equal such U.S. holder’s aggregate tax basis in the Liberty common stock surrendered by such U.S. holder in the Merger. The holding period for the shares of Middlefield common stock received by such U.S. holder in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will include the holding period for the shares of Liberty common stock exchanged therefor.

Exchange of Liberty common stock solely for cash. A U.S. holder who exchanges all of its shares of Liberty common stock solely for cash pursuant to the Merger generally will recognize capital gain or loss equal to the difference between the amount of cash received by such U.S. holder and the U.S. holder’s adjusted tax basis in the Liberty common stock exchanged therefor. Any capital gain or loss generally will be long-term capital gain or loss if the U.S. holder held the shares of Liberty common stock for more than one year at the effective time of the Merger.

Exchange of Liberty common stock for a combination of Middlefield common stock and cash. Except as discussed below, a U.S. holder who exchanges its shares of Liberty common stock for a combination of Middlefield common stock and cash pursuant to the Merger will recognize gain (but not loss) equal to the lesser of (i) the excess, if any, of the amount of cash plus the fair market value of any Middlefield common stock received in the merger, over such U.S. holder’s adjusted tax basis in the shares of Liberty common stock

surrendered by such U.S. holder in the Merger and (ii) the amount of cash received by such U.S. holder in the Merger (other than cash received in lieu of fractional shares of Middlefield common stock).

For purposes of this calculation, the fair market value of Middlefield common stock is based on the trading price of that stock on the date of the Merger, rather than the methodology used in calculating the number of shares of Middlefield common stock to be issued to the stockholder. In the case of any U.S. holder who acquired different blocks of Liberty common stock at different times and at different prices, any realized gain or loss will be determined separately for each identifiable block of shares exchanged in the Merger. A loss realized on the exchange of one block of shares cannot be used to offset a gain realized on the exchange of another block of shares, but a U.S. holder will generally be able to reduce its capital gains by capital losses in determining its income tax liability. Prior to voting on the Merger, any U.S. holder potentially in that circumstance should consult its tax advisor with regard to identifying the basis or holding periods of the particular shares of Middlefield common stock received in the Merger. In addition, Treasury Regulations under Section 358 of the Internal Revenue Code provide that where a stockholder surrenders shares of target stock in an exchange and receives cash and shares of acquirer stock, then, to the extent the terms of the exchange specify that shares of acquirer stock or cash are received in exchange for a particular share of target stock surrendered, the terms of the exchange shall control for the purpose of determining the gain to the extent the terms of the exchange are economically reasonable. Therefore, a U.S. holder might be permitted to calculate the amount of taxable gain separately for each share of Liberty common stock surrendered in the Merger based on the specific consideration received for such share. This result might be permitted if the stockholder designates, on the election form (and as specifically authorized by the Reorganization Agreement), specific shares of Liberty common stock to be exchanged for cash or to be exchanged for Middlefield common stock, as the case may be. Such a designation might result in less taxable gain to a U.S. holder even if the holder holds a single block of Liberty common stock with a uniform tax basis. However, it is unclear whether a designation described in this paragraph will be treated as satisfying the requirements of the Treasury Regulations, and whether the proration provisions of the Merger agreement may affect such designation, and, therefore, there can be no assurance that the IRS would not successfully challenge a U.S. holder that reports taxable gain on the basis of such a designation. U.S. holders therefore should consult with their tax advisors with respect to the advisability, including any benefits or risks, of making an express designation in their election form.

Generally, a U.S. holder’s aggregate tax basis in the Middlefield common stock received by that U.S. holder in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” will equal such U.S. holder’s aggregate tax basis in the Liberty common stock surrendered in the Merger, increased by the amount of taxable gain (or dividend income as described in the following paragraph, but not the special dividend addressed below in “-Treatment of the Special Dividend”), if any, recognized by such U.S. holder in the Merger (other than with respect to cash received in lieu of fractional shares of Middlefield common stock), and decreased by the amount of cash, if any, received by such U.S. holder in the Merger (other than cash received in lieu of fractional shares of Middlefield common stock). The holding period for the shares of Middlefield common stock received in the Merger, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will include the holding period for the shares of Liberty common stock exchanged therefor.

Any capital gain generally will be long-term capital gain if the U.S. holder held the shares of Liberty common stock for more than one year at the effective time of the Merger. The deductibility of capital losses is subject to limitations. All or part of the gain that a particular U.S. holder of Liberty recognizes could be treated as dividend income rather than capital gain if (i) such U.S. holder is a significant stockholder of Middlefield or (ii)

such U.S. holder’s percentage ownership, taking into account constructive ownership rules, in Middlefield after the Merger is not meaningfully reduced from what its percentage ownership would have been if it had received solely shares of Middlefield common stock rather than a combination of cash and shares of Middlefield common stock in the Merger. This could happen, for example, because of ownership of additional shares of Middlefield common stock by such holder, ownership of shares of Middlefield common stock by a person related to such

holder or a share repurchase by Middlefield from other holders of Middlefield common stock. These rules are complex and dependent upon the specific factual circumstances particular to each U.S. holder. Consequently, each U.S. holder that may be subject to those rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such U.S. holder.

Cash in Lieu of Fractional Shares of Middlefield Common Stock. A U.S. holder that receives cash instead of a fractional share of Middlefield common stock will be treated as having received the fractional share of Middlefield common stock pursuant to the Merger and then as having exchanged the fractional share of Middlefield common stock for cash in a redemption by Middlefield. In general, this deemed redemption will be treated as a sale or exchange, and a U.S. holder will recognize gain or loss equal to the difference between (i) the amount of cash received by such U.S. holder and (ii) the portion of the basis of the shares of Liberty common stock allocable to such fractional interest. Such gain or loss generally will constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder’s holding period for the Liberty common stock exchanged by such U.S. Holder is greater than one year as of the effective time of the Merger.

Medicare Tax on Net Investment Income. A U.S. holder that is an individual is subject to a 3.8% tax on the lesser of (i) his or her “net investment income” for the relevant taxable year or (ii) the excess of his or her modified adjusted gross income for the taxable year over a certain threshold (between $125,000 and $250,000 depending on the individual’s U.S. federal income tax filing status). A similar regime applies to estates and trusts. Net investment income generally would include any capital gain incurred in connection with the Merger, as well as the special dividend addressed below in “-Treatment of the Special Dividend.”

Backup Withholding and Information Reporting. Payments of cash to a U.S. holder of Liberty common stock pursuant to the Merger may, under certain circumstances, be subject to information reporting and backup withholding (currently at a rate of 28%) unless the holder provides proof of an applicable exemption satisfactory to Middlefield and the exchange agent or, in the case of backup withholding, furnishes its taxpayer identification number and otherwise complies with all applicable requirements of the backup withholding rules. The documents provided to Liberty stockholders to surrender their stock certificates for exchange in the Merger will provide an opportunity for the Liberty stockholder to provide required information. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

A U.S. holder of Liberty common stock, as a result of having received Middlefield common stock in the Merger, will be required to retain records pertaining to the Merger. In addition, each U.S. holder of Liberty common stock that is a “significant holder” will be required to file a statement with that holder’s U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3(b) setting forth that holder’s basis in the Liberty common stock surrendered and the fair market value of the Middlefield common stock and cash received in the Merger. A “significant holder” is a holder of Liberty common stock that, immediately before the Merger, owned at least 5% of the vote or value of the outstanding stock of Liberty or securities of Liberty with a basis for federal income taxes of at least $1 million.

Tax Implications to Non-U.S. Stockholders. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of Liberty common stock (other than an entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder. The rules governing the U.S. federal income taxation of non-U.S. holders are complex, and no attempt will be made herein to provide more than a limited summary of those rules. Any gain a non-U.S. holder recognizes from the exchange of Liberty common stock for Middlefield common

stock and cash in the Merger generally will not be subject to U.S. federal income taxation unless (a) the gain is effectively connected with a trade or business conducted by the non-U.S. holder in the United States, or (b) in the case of a non- U.S. holder who is an individual, such stockholder is present in the United States for 183 days or more in the taxable year of the sale and other conditions are met. Non-U.S. holders described in (a) above will be subject to tax on gain recognized at applicable U.S. federal income tax rates and, in addition, non-U.S. holders

that are corporations (or treated as corporations for U.S. federal income tax purposes) may be subject to a branch profits tax equal to 30% (or a lesser rate under an applicable income tax treaty) on their effectively connected earnings and profits for the taxable year, which would include such gain. Non-U.S. holders described in (b) above will be subject to a flat 30% tax on any gain recognized, which may be offset by U.S. source capital losses.

Treatment of the Special Dividend. The special dividend contemplated by the Reorganization Agreement is not part of the Merger consideration and is not addressed by the discussion of the Merger consideration set out above. The special dividend will be taxable to U.S. holders who are individuals as ordinary income, taxable at preferential rates applicable to “qualified dividends;” and, as discussed above in “Medicare Tax on Net Investment Income,” will be treated as “net investment income” for such purposes. Although the special dividend is not part of the Merger consideration for the purposes of the discussion above of the exchange of Liberty common stock in the Merger, the special dividend must be considered in determining whether the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. The potential amount of the special dividend has been calculated in a manner that enables Middlefield to acquire “substantially all” of the properties of Liberty within the meaning of Revenue Procedure 86-42, to be consistent with the treatment of the Merger as a “reorganization” as described in Section 368(a) of the Internal Revenue Code.

This discussion does not address tax consequences that may vary with, or are contingent upon, individual circumstances. Moreover, it does not address any non-income tax or any foreign, state or local tax consequences of the Merger.Tax matters are very complicated, and the tax consequences of the Merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local or foreign tax consequences of the Merger in light of your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws.

The Merger will be accounted for under the acquisition method of accounting in accordance with generally accepted accounting principles in the United States. Under the acquisition method of accounting, the assets and liabilities of Liberty will be recorded and assumed at estimated fair values when the Merger is consummated. The excess of the estimated fair value of Middlefield common stock issued and the cash proceeds paid over the net fair values of the assets acquired, including identifiable intangible assets, and liabilities assumed will be recorded as goodwill and will not be deductible for income tax purposes. Goodwill is subject to an annual test for impairment and the amount impaired, if any, is charged as an expense at the time of impairment.

Middlefield registered with the SEC under the Securities Act of 1933 the issuance of common stock to Liberty stockholders in the Merger. No restrictions on the sale or other transfer of Middlefield common stock issued in the Merger will be imposed solely as a result of the Merger, except for restrictions on the transfer of Middlefield common stock issued to any Liberty stockholder who becomes an affiliate of Middlefield for purposes of SEC Rule 144. The term affiliate is defined in Rule 144 and generally includes a company’s executive officers, directors, and stockholders beneficially owning 10% or more of the company’s outstanding shares.

Annex A is a complete copy of the Reorganization Agreement.We encourage you to read the Reorganization Agreement carefully. It is the principal legal document governing the Merger.

The Reorganization Agreement contains representations and warranties of Liberty and Middlefield. The assertions within those representations and warranties are qualified by information contained in confidential disclosure schedules the parties delivered to each other when they executed the Reorganization Agreement. In addition, some of the representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from the standard of materiality generally applicable to statements made by a corporation to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts ~~or for~~as of any ~~other purpose, at~~specified date. We urge you to read the ~~time they were made or otherwise.~~full text of the Reorganization Agreement carefully.

When Liberty merges into The Middlefield Banking Company, The Middlefield Banking Company will be the surviving company. The separate corporate existence of Liberty will cease and the articles of incorporation and code of regulations of The Middlefield Banking Company in effect immediately before the Merger will be the articles of incorporation and code of regulations of the surviving company. The directors and officers of The Middlefield Banking Company immediately before the Merger will be the directors and officers of the surviving company. Liberty stockholders receiving cash Merger consideration only will not participate in Middlefield’s future earnings and potential growth, but also will not bear the risk of loss for the surviving company’s business or the risk of decreases in the value of that business. Liberty stockholders receiving Middlefield common stock as Merger consideration will participate in the surviving company’s future earnings and potential growth through their ownership of stock, with all other rights associated with ownership of Middlefield common stock, such as the right to dividends and the right to vote at annual and special meetings.

The Merger will occur on a date to be specified by Middlefield and Liberty within five days after all necessary closing ~~condition~~conditions are satisfied unless otherwise agreed. The conditions include receipt of all ~~regulatory and~~ stockholder ~~approvals and expiration of all regulatory waiting periods.~~approvals. The Merger will become effective as of the date specified in the certificate of Merger to be filed with the Ohio Secretary of State. As of the date of this joint proxy statement/prospectus, ~~assuming regulatory approvals are obtained without significant delay,~~ the parties expect that the Merger will be effective byin the ~~end~~first quarter of ~~2016.~~2017. However, Liberty and Middlefield cannot assure you that all necessary conditions to the Merger will be satisfied or when they will be satisfied.

If the Merger is not completed by May 30, 2017, the Reorganization Agreement may be terminated by Middlefield or by Liberty, unless the failure of the closing to occur by that date is due to the failure of the party seeking to terminate the Reorganization Agreement to perform or observe its covenants and agreements in the Reorganization Agreement. Either party may also terminate for uncured breaches of representations, warranties or covenants sufficient to cause a failure of a closing condition; for failure of the other party to obtain stockholder approval of the Merger; ~~for failure to obtain regulatory approval;~~ or in the event the Merger has not been completed by May 30, 2017. The parties may mutually agree to extend the May 30, 2017 deadline. ~~If regulatory approvals are obtained, the terms of approval are likely to impose a deadline of six months to one year for completion of the approved transaction.~~

As part of the Merger transaction, MBC Interim Bank, a wholly owned interim bank subsidiary of Middlefield formed for the sole purpose of facilitating the Merger, will first merge into Liberty, with Liberty as the surviving company, followed immediately by Liberty’s merger into The Middlefield Banking Company.

When the Merger is completed, Liberty stockholders will receive from Middlefield a combination of cash and Middlefield common stock. Subject to allocation procedures in the Reorganization Agreement ensuring that approximately 45% of the outstanding Liberty common stock is converted into the right to receive Middlefield common stock and the remaining outstanding Liberty common stock is converted into the right to receive cash, at the effective time of the Merger Liberty common stock not owned by Middlefield will be converted into the right to receive either:

Liberty common stockholders may elect to receive cash, stock, or a mix of cash and stock, subject to adjustment such that 45% of the Liberty shares exchanged in the Merger are exchanged for Middlefield common stock.

It is not part of the Merger consideration, but the Reorganization Agreement also provides that Liberty will declare a special dividend to its stockholders before the Merger closing. The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will not receive Merger consideration for its 23,218 Liberty shares but it will be entitled to the special dividend payment.

Liberty stockholders will own approximately ~~18.7%~~20% of the outstanding Middlefield common stock after the Merger.

Middlefield will not issue fractional shares. A holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all Liberty common stock owned by the holder at the effective time of the Merger) will instead receive cash, without interest, in an amount equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

Once the Merger is complete, the Exchange Agent will mail to each holder of Liberty common stock transmittal materials and instructions for delivering share certificates to the Exchange Agent. American Stock Transfer & Trust Company, LLC will act as Exchange Agent. Liberty stockholders must use the letter of transmittal to exchange Liberty share certificates for Merger consideration. Do not send in share certificates with your proxy form.

Liberty’s compensation arrangements for officers and employees include equity-based awards, including stock options and phantom awards. There are option awards outstanding for ~~89,561~~13,572 shares, all of which are vested. At the effective time of the Merger each outstanding and unexercised option to purchase Liberty common stock will be cancelled in exchange for a cash payment equal to (x) the positive difference, if any, between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise. There are also outstanding 2,000 phantom share awards made in 2013. The phantom share awards consist of the right to a cash payment equal to the positive difference between Liberty’s stock value on December 31, 2016 and the stock value on the award date, multiplied by the number of phantom shares awarded, with value being determined by Liberty’s board of directors. The total cash payment for cancellation of the options and phantom awards is estimated to be ~~$1,147,516.~~$161,931. The $41.09 figure is the sum of the $37.96 per share cash Merger consideration and the $3.13 per share special dividend.

Covenants Affecting the Conduct of Business Until the Merger Occurs. The Reorganization Agreement requires Liberty to conduct its business in the ordinary course in the period before the Merger occurs and to

reasonably preserve intact its assets and business organization. Liberty is required by the Reorganization Agreement to grant Middlefield access to Liberty properties and non-confidential books and records, making internal financial information available to Middlefield as well and keeping Middlefield informed regarding Liberty’s operations as Middlefield may request. Liberty must keep Middlefield informed of material developments in its business or of any threatened litigation, meeting monthly with Middlefield personnel concerning Liberty’s operations and providing monthly reports about problem assets. Liberty will cooperate with Middlefield regarding integration of data processing and related electronic information systems. Liberty also must maintain commercially reasonable business insurance. Liberty must notify Middlefield of any stockholder litigation arising out of the Reorganization Agreement, giving Middlefield the opportunity to participate at its own expense in the defense or settlement of the litigation.

If all necessary bank regulatory approvals and stockholder approvals of the Reorganization Agreement and Merger are obtained, Liberty will declare, upon receipt of OCC approval, a special dividend payable in cash to Liberty stockholders at or before Merger closing. The amount of the special dividend is estimated to be approximately $3.0 million in the aggregate, or $3.13 per share, but under section 6.1(b) of the Reorganization Agreement, the amount can increase based on Liberty’s and Middlefield’s tax advisers’ mutual determination of the potential effect of the special dividend on the ability of Liberty’s tax counsel to render an opinion at closing that the Merger qualifies as a tax-free reorganization under Internal Revenue Code section 368(a). The Reorganization Agreement requires in section 6.1(c) that Liberty maintain Tier 1 capital of at least $28.3 million, after taking the special dividend into account but excluding the effect of identified expenses arising out of the Reorganization Agreement and Merger. For this purpose tier 1 capital is defined in OCC rules.

Liberty also agreed to a number of restrictions for the period until the Merger becomes effective, agreeing that without Middlefield’s advance consent Liberty will not –

(A) take any action that would prevent or impede the Mergers from qualifying as a reorganization under Section 368(a) of the Internal Revenue Code of 1986,

(B) change or waive any provision of Liberty’s articles of association or bylaws,

(C) issue any shares of Liberty common stock or right to acquire Liberty common stock, split, combine, or reclassify any shares of capital stock, declare, set aside, or pay a dividend, or redeem or acquire any shares of capital stock, except for shares issued upon exercise of outstanding rights, except for regular cash dividends in amounts and with payment and record dates consistent with past practice (provided that declaration and payment of the final Liberty dividend before the Effective Time is coordinated with Middlefield Banc Corp. so that holders of Liberty common stock do not receive dividends on both Liberty common stock and Middlefield Banc Corp. common stock for the same period), and except for the special dividend payable under the terms of the Reorganization Agreement,

Liberty will not hire or promote an employee to a rank having a title of vice president or other more senior rank or hire a new employee at an annual rate of compensation exceeding $40,000, but Liberty may hire at-will non-officer employees at an annual compensation rate not exceeding $30,000 to fill vacancies arising in the ordinary course of business. Liberty may not hire a new employee without first seeking to fill the position internally,

(G) enter into or modify a pension, retirement, stock purchase, stock appreciation right, stock grant, savings, profit sharing, deferred compensation, supplemental retirement, consulting, bonus, group insurance, or other employee benefit, incentive, or welfare contract, plan, or arrangement, or any trust agreement for any director, officer, or employee, or make a contribution to a defined contribution or defined benefit plan not in the ordinary course of business or not consistent with past practice,

Middlefield has also agreed to a limited set of restrictions on its business in the period before the Merger is completed. Specifically, Middlefield has agreed that in the period before the Merger is completed it and The Middlefield Banking Company will conduct business in the usual and ordinary course, will maintain commercially reasonable business insurance, and will not take any action that –

Middlefield must deposit with the Exchange Agent before Merger closing cash and Middlefield common stock sufficient to pay the Merger consideration to Liberty stockholders. Until the Merger occurs Middlefield may not issue additional shares of common stock or rights to acquire stock except under Middlefield’s equity-based benefit plans or under Middlefield’s dividend reinvestment plan. Middlefield also is required to grant Liberty access to Middlefield properties and non-confidential books and records, making internal financial information available to Liberty as well. Middlefield is also obligated to maintain insurance, supplement its disclosures to Liberty, and seek consents necessary for closing.

Nasdaq Listing. Middlefield will cause the Middlefield common stock being issued in the Merger to be authorized for listing on Nasdaq, subject to official notice of issuance, before the Merger becomes effective.

Middlefield Board of Directors. Following the Merger, the Board of Directors of Middlefield will cause two current members of the Board of Directors of Liberty, William A. Valerian and Thomas W. Bevan, to be appointed to the Board of Directors of Middlefield.

Employee Matters.Liberty employees who become employees of Middlefield or The Middlefield Banking Company when the Merger is completed will participate in employee benefit plans of general applicability to the same extent as similarly-situated employees of Middlefield and The Middlefield Banking Company, and for vesting and eligibility purposes the former Liberty employees will be credited for their service as Liberty employees. Middlefield and The Middlefield Banking Company are not contractually committed to retaining Liberty employees but have agreed to retain as many Liberty officers and employees as is commercially reasonable and possible, agreeing also to consider Liberty personnel for any positions becoming open at Middlefield or The Middlefield Banking Company after the date of the Reorganization Agreement. Middlefield will honor employment, change-in-control severance, and split dollar insurance agreements of Liberty, but is not required to pay and will not pay any benefits that would constitute parachute payments under Internal Revenue Code sections 280G and 4999. Those provisions of the Internal Revenue Code impose a 20% excise tax on parachute payments in a change in control, denying to the employer a compensation deduction for the benefits constituting parachute payments. For Liberty employees whose service does not continue after the Merger or who are terminated without cause within one year after the Merger, Middlefield has agreed in the Reorganization Agreement to pay them cash severance equal to one week of base pay for each year of service, with a minimum of four weeks of base pay and a maximum of 26, and to make available career counseling and professional counseling. Middlefield also may pay retention or incentive bonuses to selected Liberty personnel whose service is critical to the Merger-related transition, such as data processing personnel.

Indemnification and Directors’ and Officers’ Insurance. For a period ending six years after the effective time of the Merger, Middlefield will indemnify and hold harmless, to the fullest extent provided under Liberty’s articles of association and bylaws, each present and former director and officer of Liberty and its subsidiaries from liabilities arising out of or pertaining to matters existing or occurring at or before the effective time of the Merger, including the transactions under the Reorganization Agreement. Middlefield has also agreed that for a period of six years after the Merger Middlefield will maintain directors’ and officers’ liability insurance coverage for actions, omissions, or events occurring before the effective time of the Merger, including the transactions under the Reorganization Agreement, and covering Liberty directors and officers on the July 28, 2016 date of the Reorganization Agreement. The insurance will be on terms and conditions substantially equivalent to Liberty’s directors’ and officers’ liability insurance coverage, but Middlefield is not required to incur annual premium expense greater than 150% of Liberty’s annual premium cost as of July 28, 2016. Instead of Middlefield’s

continued maintenance of directors’ and officers’ liability insurance coverage, before the effective time of the Merger, Middlefield may purchase and pay for a tail policy for directors’ and officers’ liability insurance on the terms described in this paragraph, or Liberty may do so with Middlefield’s consent.

Regulatory Matters. Middlefield agreed to promptly prepare and file with the SEC a registration statement on Form S-4, of which this joint proxy statement/prospectus is a part. Liberty prepared the portion of this joint proxy statement/prospectus constituting the proxy statement of Liberty. Middlefield and Liberty agreed to use commercially reasonable efforts to have the Form S-4 declared effective under the Securities Act of 1933 as promptly as practicable after such filing, and Middlefield and Liberty agreed to mail or deliver the joint proxy statement/prospectus to their respective stockholders. Middlefield also will use commercially reasonable efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to complete the Merger. Middlefield and Liberty will cooperate with each other and use commercially reasonable efforts to promptly prepare and file all necessary documentation and obtain all permits, consents, approvals, and authorizations of all third parties and governmental entities that are necessary to complete the Merger. The Reorganization Agreement requires both Middlefield and Liberty to file for all necessary regulatory approvals. See “THE MERGER – Regulatory Approvals Required.”

Stockholder Approval. Both Middlefield and Liberty are required by the Reorganization Agreement to call and hold a meeting of stockholders to enable stockholders to consider and vote on the Reorganization Agreement and the Merger. Liberty’s board of directors also committed in the Reorganization Agreement to recommend that Liberty stockholders vote in favor of adopting and approving the Reorganization Agreement, committing also to ensure that any anti-takeover provisions of Liberty’s articles of association, bylaws, or applicable state law are made inapplicable to the Merger or to minimize the impact of any applicable antitakeover provisions. The board is permitted by the Reorganization Agreement to decline to recommend a vote in favor or to withdraw, modify, or change the recommendation to stockholders if, after consultation with financial and legal advisors, the board concludes that recommending a vote in favor of adoption and approval or failing to withdraw, modify, or change the recommendation would breach the directors’ fiduciary duties to stockholders.

No Solicitation. The Reorganization Agreement prohibits Liberty and its officers, directors, employees, representatives, affiliates, and agents from (x) initiating, soliciting, knowingly encouraging, or furnishing assistance or nonpublic information for an inquiry or the making of a proposal that constitutes or that may reasonably be expected to lead to an acquisition proposal, (y) discussing, negotiating, or making a proposal that constitutes or that may reasonably be expected to lead to an acquisition proposal, or (z) agreeing to or endorsing an acquisition proposal. For this purpose the term “acquisition proposal” means a proposal or offer (other than Middlefield’s) involving Liberty for (1) merger, consolidation, share exchange, business combination, or other similar transactions, (2) sale, lease, exchange, mortgage, pledge, transfer, or other disposition of 25% or more of the assets of Liberty in a single transaction or series of transactions, or (3) a tender offer or exchange offer for 25% or more of the outstanding shares of Liberty common stock or the filing of a registration statement under the Securities Act of 1933 for the offer of shares in exchange for Liberty stock. Acquisition proposal also includes a publicly announced proposal, plan, or intention to do any of the foregoing or any agreement to engage in any of the foregoing. Liberty would not violate this obligation, however, if it furnishes information to and negotiates with a person making an acquisition proposal if two conditions are satisfied: (1) the acquisition proposal is not solicited by Liberty and (2) Liberty’s board concludes in good faith, after consulting with legal and financial advisors, that the unsolicited acquisition proposal is reasonably likely to result in a transaction more favorable to Liberty stockholders from a financial point of view than the Merger transaction under the Reorganization Agreement. A proposal satisfying both of those conditions is referred to as a “Superior Proposal.” Liberty must notify Middlefield within two business days after receiving inquiries, proposals, offers, or information requests.

Liberty’s representations and warranties to Middlefield in the Reorganization Agreement concern the following topics and are qualified by the confidential disclosure schedules delivered to Middlefield:

Middlefield’s representations and warranties to Liberty in the Reorganization Agreement concern the following topics and are qualified by the confidential disclosure schedules delivered to Liberty:

Many of the representations and warranties of Liberty and Middlefield are qualified regarding “materiality” or “material adverse effect.” For purposes of the Reorganization Agreement, a “material adverse effect” means an effect that is material and adverse to the financial condition, results of operations, or business of Middlefield and its subsidiaries taken as a whole, or of Liberty and its subsidiaries taken as a whole, or materially impairs the ability of either Liberty, on one hand, or Middlefield and The Middlefield Banking Company, on the other hand, to perform the obligations under the Reorganization Agreement or otherwise materially impedes consummation of the Merger, except that the following circumstances or events are excluded when determining whether a material adverse effect has occurred:

(1) the impact of (x) changes in laws, rules, or regulations affecting banks or their holding companies generally, or interpretations thereof by courts or governmental agencies, (y) changes in GAAP, or (z) changes in regulatory accounting requirements, in any case applicable to financial institutions or their holding companies generally and not specifically relating to Liberty, on one hand, or Middlefield or any Middlefield subsidiary, on the other hand,

(2) announcement of the Reorganization Agreement by press release mutually agreed to by Liberty and Middlefield or by Form 8-K filed by Middlefield,

(3) any act or omission of Liberty required under the Reorganization Agreement or taken or omitted to be taken with the express written permission of Middlefield,

(4) any act or omission of Middlefield or The Middlefield Banking Company required under the Reorganization Agreement or taken or omitted to be taken with the express written permission of Liberty,

(5) the direct effects of compliance with the Reorganization Agreement on the operating performance of the parties, including expenses incurred by the parties investigating, negotiating, documenting, effecting, and consummating the transactions under the Reorganization Agreement,

(6) any changes after the date of the Reorganization Agreement in general economic or capital market conditions affecting banks or their holding companies generally, and

(7) any changes in national or international political or social conditions, including engagement by the United States in hostilities, whether by the declaration of a national emergency or war, or the occurrence of a military attack upon or within the United States.

The representations and warranties in the Reorganization Agreement do not survive the effective time of the Merger and, as described below under “– Termination”, if the Reorganization Agreement is terminated there will be no liability under the representations and warranties of the parties or otherwise under the Reorganization Agreement unless a party knowingly breached the Reorganization Agreement.

The Reorganization Agreement representations and warranties of Middlefield and Liberty were made solely for purposes of that agreement and as of specific dates. The representations, warranties, and covenants in the Reorganization Agreement ~~were made for the benefit of the parties to the Reorganization Agreement only,~~ may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Reorganization Agreement instead of establishing matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those generally applicable to investors. ~~Investors are not third-party beneficiaries under the Reorganization Agreement.~~ When reviewing the representations, warranties, and covenants contained in the Reorganization Agreement or summarized in this joint proxy statement/prospectus, it is important to bear in mind that the representations, warranties, and covenants and the summary are not intended by the parties to the Reorganization Agreement to be characterizations of the actual state of facts or condition of

Middlefield, Liberty, or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties,

and covenants may have changed after the date of the Reorganization ~~Agreement, which subsequent information might or might not be disclosed in Middlefield’ public disclosures.~~Agreement. For the foregoing reasons, the representations, warranties, and covenants or any summary of those provisions should not be read alone and should instead be read in conjunction with the other information contained in the reports, statements, and filings that Middlefield publicly files with the SEC. For more information regarding these documents, see the section entitled “Where You Can Find More Information” in the forepart of this document.

Conditions to Each Party’s Obligations. The obligations of Middlefield and Liberty to complete the Merger are subject to satisfaction of the following conditions:

Conditions to Middlefield’s Obligations. Middlefield’s obligation to complete the Merger is subject to satisfaction of these additional conditions:

Conditions to Liberty’s Obligations. Liberty’s obligation to complete the Merger is subject to satisfaction of these additional conditions:

The Reorganization Agreement may be terminated before the effective time of the Merger, whether before or after approval by Liberty stockholders and Middlefield stockholders:

Liberty must pay a termination fee of $1.65 million to Middlefield if Middlefield terminates the Reorganization Agreement because Liberty’s board fails to recommend to Liberty stockholders adoption and approval of the Reorganization Agreement, or because Liberty’s board withdraws or adversely changes the recommendation in favor of the Reorganization Agreement, or because Liberty accepts a competing acquisition proposal. Liberty would also be required to pay the $1.65 million termination fee to Middlefield if Liberty terminates the Reorganization Agreement because it accepts a superior acquisition proposal. Finally, if a competing acquisition proposal is made to Liberty and thereafter Middlefield terminates the Reorganization Agreement because of a breach by Liberty or Middlefield or Liberty thereafter terminate the agreement because Liberty stockholders do not adopt and approve the Reorganization Agreement and Merger, Liberty will have to pay the $1.65 million termination fee to Middlefield if within one year after termination Liberty enters into a definitive agreement for a competing acquisition proposal.

If the Reorganization Agreement terminates, it will be deemed void, without any liability on the part of any of the parties, except in the case of a party’s willful breach of the Reorganization Agreement, and except for a

potential termination fee payment by Liberty. Reorganization Agreement provisions for confidentiality of the parties’ information, the termination fee, and other technical provisions would remain effective despite termination of the Reorganization Agreement.

Liberty and Middlefield may amend the Reorganization Agreement by action of their boards of directors, whether before or after stockholder approval of the Reorganization Agreement. If the amendment decreases the amount or value of Merger consideration or the form of the Merger consideration additional approval of Liberty stockholders would be necessary. At any time before effective time of the Merger a party may extend the time for performance of the other party’s obligations, waive inaccuracies in the other party’s representations and warranties, or waive compliance with agreements or conditions in the Reorganization Agreement.

Middlefield common stock is listed on Nasdaq, trading under the symbol MBCN. Middlefield will apply to Nasdaq to list the additional common stock being issued in the Merger. It is a condition to both parties’ obligation to complete the Merger that Nasdaq approve Middlefield’s application, subject to official notice of issuance.

Fees and expenses incurred by a party regarding the Merger, the Reorganization Agreement, and the transactions under the Reorganization Agreement will be paid by the party incurring the fees and expenses, regardless of whether the Merger is completed, but if the Reorganization Agreement is terminated because of a party’s willful and material breach, the breaching party is liable for damages and all costs and expenses.

The rights of Liberty stockholders who receive Middlefield common stock in the Merger will be governed by the Ohio General Corporation Law (OGCL) and by Middlefield’s Second Amended and Restated Articles of Incorporation and Code of Regulations. Their stockholder rights currently are determined by Liberty’s Amended and Restated Articles of Association and its By-Laws. Federal law authorizing national banking associations permits national banks to select the state law that will control corporate governance questions not specifically treated in the articles of association and bylaws. Liberty’s By-Laws state that the OGCL apply.

Although the rights of Middlefield stockholders and the rights of Liberty stockholders are similar, there are some differences between provisions of the Second Amended and Restated Articles of Incorporation of Middlefield and the Amended and Restated Articles of Association of Liberty, and differences between provisions of the Amended Code of Regulations of Middlefield and the By-Laws of Liberty. The following comparison of stockholder rights is not a complete description of all differences individual Liberty stockholders might consider important.

Director Compensation. The following table shows the compensation paid to nonemployee directors for their service in 2015, including their service on our board, on the board of The Middlefield Banking Company, and on board committees of Middlefield and The Middlefield Banking Company. The compensation of Directors Caldwell and Heslop is included in the Summary Compensation Table. Director Rose was not a director in 2015.

Middlefield directors receive compensation of $750 for each board and committee meeting attended. Middlefield’s Chairman of the Board receives additional annual compensation of $4,000. The Middlefield Banking Company directors receive compensation of $1,800 per month less $100 for each meeting not attended in a particular month. The Middlefield Banking Company directors also receive $500 in committee fees for each meeting attended. The 2015 compensation of Director Jones includes $2,700 for his service on our Central Ohio Regional Advisory Board. Directors of EMORECO, Inc. receive no compensation for board service.

At the 2001 annual meeting shareholders approved the form and use of indemnification agreements for directors. The indemnification agreements allow directors to select the most favorable indemnification rights provided under (1) Middlefield’s Second Amended and Restated Articles of Incorporation or Regulations in effect on the date of the indemnification agreement or on the date expenses are incurred, (2) state law in effect on the date of the indemnification agreement or on the date expenses are incurred, (3) any liability insurance policy in effect when a claim is made against the director or on the date expenses are incurred, and (4) any other indemnification arrangement otherwise available. The agreements cover all fees, expenses, judgments, fines, penalties, and settlement amounts paid in any matter relating to the director’s role as a Middlefield director, officer, employee, agent, or when serving as Middlefield’s representative with respect to another entity. Each indemnification agreement provides for the prompt advancement of all expenses incurred in connection with any proceeding subject to the director’s obligation to repay those advances if it is determined later that the director is not entitled to indemnification.

Executive Officers Who Do Not Also Serve as Directors. There are no family relationships among any of Middlefield’s directors or executive officers. Executive officers who do not also serve as directors are –

Executive Compensation. The majority of the compensation of executive officers is paid by The Middlefield Banking Company, but compensation shown in the table is aggregate compensation paid by Middlefield, The Middlefield Banking Company, and Emerald Bank. No compensation is paid by EMORECO, Inc. Emerald Bank merged into The Middlefield Banking Company on January 20, 2014.

Perquisites and other personal benefits provided to each of the named executive officers in 2015 and 2014 had a value of less than $10,000. The value of insurance on the lives of the named executive officers is not

included in the Summary Compensation Table because the executives have no interest in the policies. However, the executives are entitled to designate the beneficiary of death benefits payable by The Middlefield Banking Company under executive survivor income agreements. See the “Executive Survivor Income Agreements” discussion below.

Annual Incentive Plan. In 2003 The Middlefield Banking Company established the Annual Incentive Plan, a short-term cash incentive plan that rewards employees with additional cash compensation if specific objectives are achieved. An employee’s potential cash incentive payment under the Annual Incentive Plan depends upon two factors: (x) the employee’s position, which establishes a maximum cash incentive award as a percent of base salary, and (y) the degree to which the performance targets, such as targeted net income, and individual performance targets, are achieved. Annual incentive payments under the plan for a particular year generally are based on objective financial performance criteria established by the board, with the Compensation Committee’s recommendation. A copy of the plan is included as exhibit 10.22 to the Form 8-K Current Report that we filed with the SEC on June 12, 2012, which is available for viewing or download at www.sec.gov. All employees are eligible for awards under the Annual Incentive Plan. The plan is terminable by the board at any time.

The bank-wide performance objectives that had to be achieved in 2015 in order for Messrs. Caldwell, Heslop, and Stacy to receive a cash incentive payment under the plan included a net income goal, a goal for reduction of adversely classified loans as a percent of the sum of tier 1 capital and the allowance for loan and lease losses, a goal for loan growth, and a goal having to do with the regulatory and supervisory status of Middlefield and The Middlefield Banking Company. Please see the Form 8-K Current Report filed by Middlefield with the SEC on June 18, 2015 for additional information. In future years other financial performance measures could be taken into account, such as return on average equity (ROAE), return on average assets (ROAA), deposit growth, and net interest margin. The Compensation Committee also considers individual performance goals.

2007 Omnibus Equity Plan. The 2007 Omnibus Equity Plan authorizes the issuance of 160,000 shares of Middlefield common stock. Middlefield’s Compensation Committee administers the Omnibus Equity Plan. Shares of common stock issued under the Omnibus Equity Plan may be treasury shares, authorized and unissued shares not reserved for any other purpose, or a combination of treasury shares and authorized but unissued shares. Awards to employees may take the form of incentive stock options, orISOs, that qualify for favored tax treatment under Internal Revenue Code section 422, stock options that do not qualify under section 422, referred to asNQSOs, stock appreciation rights, orSARs, restricted stock, and performance shares. In contrast to the kinds of awards that may be made to employees, non-employee directors are eligible for awards of NQSOs and restricted stock only. The terms of each award are stated in award agreements. Of the shares authorized for issuance under the Omnibus Equity Plan, up to one half may be reserved for issuance under incentive stock options. The aggregate number of shares underlying awards granted to an individual participant in a single year may not exceed 16,000.

Unless the participant’s award agreement provides otherwise, when a participant employee’s service terminates or when a non-employee director participant’s service terminates the portion of any award held by the participant that is not exercisable is forfeited. All NQSOs, SARs, and ISOs held by the participant that are exercisable are forfeited if not exercised before the earlier of the expiration date specified in the award agreement or 90 days after termination occurs. However, all of a participant’s outstanding awards are forfeited if the participant’s employment or director service terminates for cause or if in Middlefield’s judgment a basis for termination for cause exists, regardless of whether the awards are exercisable and regardless of whether the participant’s employment or director service actually terminates. However, shares of restricted stock or performance shares that have been released from escrow and distributed to the participant are not affected by a termination for cause.

If a change in control of Middlefield occurs, the Compensation Committee has broad authority and sole discretion to take actions it deems appropriate to preserve the value of participants’ awards. In general, a change in control means one or more of the following events occur –

Executive Deferred Compensation Agreements. The Middlefield Banking Company entered into executive deferred compensation agreements with Messrs. Caldwell, Heslop, and Stacy on December 28, 2006. Amended on May 9, 2008 for compliance with Internal Revenue Code section 409A, the executive deferred compensation agreements provide supplemental retirement income benefits. The arrangement is noncontributory, meaning contributions can be made solely by The Middlefield Banking Company. For each year the executive remains employed with The Middlefield Banking Company, until attaining age 65, The Middlefield Banking Company may credit each executive with a contribution equal to 5% of the executive’s base annual salary. Contributions exceeding 5% of salary are conditional on achievement of performance goals: (x) The Middlefield Banking Company’s net income for the plan year and (y) The Middlefield Banking Company’s peer ranking for the plan year, based on the Uniform Bank Performance Report available on the Federal Financial Institutions Examination Council’s website at www.ffiec.gov/UBPR.htm. The UBPR is an analytical tool created for bank supervisory, examination, and management purposes. In a concise format, the UPBR shows the impact of management decisions and economic conditions on a bank’s performance and balance-sheet composition.

Each of the two performance goals can account for a contribution of up to 7.5% of the executive’s base annual salary. The net income goal for each year is established by the Compensation Committee by March 31 of that year. The Compensation Committee’s decisions are not final unless approved by a majority of Middlefield’s independent directors.

Executive Survivor Income Agreements. The Middlefield Banking Company entered into executive survivor income agreements with executives in June 2003, including Messrs. Caldwell, Heslop, and Stacy. The agreements promise a specific cash benefit payable by The Middlefield Banking Company to an executive’s designated beneficiary at the executive’s death, provided the executive dies before attaining age 85. The benefit would be paid to the executive’s beneficiary if the executive dies in active service to The Middlefield Banking Company, but it also would be payable for death occurring after the executive’s termination of service if the executive terminated (x) because of disability, or (y) within 12 months after a change in control of Middlefield, or (z) after having attained age 55 with at least ten years of service to The Middlefield Banking Company or after having attained age 65.

The total death benefit payable to Mr. Caldwell’s beneficiaries if he dies in active service to The Middlefield Banking Company is $471,741, the benefit payable to Mr. Heslop’s beneficiaries is $368,970, and

the benefit payable to Mr. Stacy’s beneficiaries is $222,619. For death after terminating active service with The Middlefield Banking Company, the death benefit for Mr. Caldwell’s beneficiaries is $471,741, $368,970 for Mr. Heslop’s beneficiaries, and $111,309 for Mr. Stacy’s beneficiaries. To assure itself of funds sufficient to pay the promised death benefits, The Middlefield Banking Company purchased insurance on the executives’ lives with a single premium payment. The Middlefield Banking Company owns the policies and is the sole beneficiary. Of the total premium paid for the insurance on the various executives’ lives, $495,873 is attributable to insurance purchased on the life of Mr. Caldwell, $447,351 is attributable to insurance on the life of Mr. Heslop, and $333,890 is attributable to insurance purchased on the life of Mr. Stacy. The premium amounts are not included in the Summary Compensation Table. The Middlefield Banking Company expects the policies’ death benefits to be sufficient to pay all benefits promised under the executive survivor income agreements.

Severance Agreements. Middlefield and its subsidiaries do not have written employment agreements with officers, although Middlefield entered into severance agreements with executives, including Messrs. Caldwell, Heslop, and Stacy. The severance agreements provide that the executive is entitled to severance compensation if a change in control occurs during the term of the agreement. The severance compensation is payable in a single lump sum. For purposes of the severance agreements, the term change in control is defined as it is defined in Internal Revenue Code section 409A and implementing rules. In the case of executives other than Messrs. Caldwell, Heslop, and Stacy, the lump-sum severance benefit is payable immediately after involuntary termination without cause or voluntary termination with good reason occurring within 24 months after a change in control. Rather than being contingent on a separation from service after a change in control, the lump-sum benefit of Messrs. Caldwell, Heslop, and Stacy is payable immediately after a change in control occurs.

The agreements promise to each executive a lump-sum payment calculated as a multiple of the executive’s salary and the executive’s cash bonus and cash incentive compensation. The multiple of compensation payable under the severance agreements is 2.5 times in the case of Mr. Caldwell and Mr. Heslop and two times compensation for other executives. The agreements also promise continued life, health, and disability insurance coverage for 24 months after employment termination and legal fee reimbursement if the severance agreements are challenged after a change in control.

Retirement Plan. Middlefield does not maintain a defined benefit or actuarial plan providing retirement benefits for officers or employees based on actual or average final compensation. But The Middlefield Banking Company maintains a section 401(k) employee savings and investment plan for substantially all employees and officers who have more than one year of service. The bank’s contribution to the plan is based on 50% matching of voluntary contributions, up to 6% of compensation. An eligible employee may contribute up to 15% of his or her salary. Employee contributions are vested at all times. Bank contributions are fully vested after six years, vesting in 20% annual increments beginning with the second year. Employees also have life insurance benefits under a group term life insurance program, paying benefits to an employee’s beneficiary if the employee dies while employed by The Middlefield Banking Company, up to the lesser of (x) twice the employee’s annual salary at the time of death or (y) $200,000.

Internal Revenue Code Limits. The qualifying compensation regulations issued by the Internal Revenue Service under Internal Revenue Code section 162(m) state that no deduction is allowed for applicable employee remuneration paid by a publicly held corporation to a covered employee to the extent that the remuneration exceeds $1 million for the applicable taxable year, unless specified conditions are satisfied. Salary and bonus amounts deferred by executives are not subject to section 162(m). Currently, Middlefield’s remuneration is not expected to exceed $1 million for any employee. Therefore, Middlefield does not expect that compensation will be affected by the qualifying compensation regulations. The Compensation Committee and Middlefield’s board intend to maintain executive compensation within the section 162(m) deductibility limits, but could permit compensation exceeding the section 162(m) limits in the future.

Transactions with Related Parties. Middlefield directors and executive officers and their associates are customers of and enter into banking transactions with The Middlefield Banking Company in the ordinary course

of business. Middlefield expects that these relationships and transactions will continue. The transactions with directors, executive officers, and their associates have not involved more than the normal risk of collectability and have not presented other unfavorable features. Loans and commitments to lend included in these transactions were made and will be made on substantially the same terms – including interest rates and collateral – as those prevailing at the time for comparable transactions with persons not affiliated with Middlefield.

The following table shows as of December 31, 2015 unvested and unearned stock awards and the number of shares acquirable, exercise prices, and expiration dates of all unexercised stock options held by the executives identified in the Summary Compensation Table.

Middlefield is a one-bank holding company. Middlefield’s principal subsidiary is The Middlefield Banking Company, an Ohio-chartered, nonmember commercial bank. Middlefield’s other subsidiary, EMORECO Inc., is an asset resolution corporation dedicated to the resolution and disposition of troubled assets of a central-Ohio bank that Middlefield acquired in 2007, specifically nonperforming loans and other real estate owned (“OREO”) held by the acquired bank as the result of borrower defaults on real estate-secured loans. That bank, Emerald Bank, operated as a separate subsidiary of Middlefield from 2007 through 2013, merging into The Middlefield Banking Company on January 20, 2014. At the end of September 2016 The Middlefield Banking Company had total assets of $760.6 million and more than 140 employees.

The Middlefield Banking Company offers a broad range of banking services, including online banking and bill payment services for individuals and online cash management services for business customers at www.middlefieldbank.com. The Middlefield Banking Company’s customers are small and medium-sized businesses, professionals, small business owners, and retail customers. Loan products include operational and working capital loans, loans to finance capital purchases, term business loans, residential construction loans, selected guaranteed or subsidized loan programs for small businesses, professional loans, residential and mortgage loans, and consumer installment loans to purchase automobiles, boats, make home improvements, and for other personal expenditures. The Middlefield Banking Company makes available customary deposit-related products and services, such as checking, savings, negotiable order of withdrawal accounts, money market accounts, time certificates of deposit, safe deposit facilities, and travelers’ checks.

The Middlefield Banking Company’s operations have historically been concentrated in the area east of Liberty’s market, in largely rural areas with a large Amish population. The Middlefield Banking Company’s business originated in this market and was not an outgrowth of the nearby Cleveland-area or Akron-area markets. This includes Geauga County, where The Middlefield Banking Company’s business began in 1901 and where four of its ten offices are located, and northern Portage County, where two offices are located, with a seventh office in Cortland in Trumbull County, an office in Orwell in southern Ashtabula County, and two offices in central Ohio, in Franklin County. The Middlefield Banking Company’s eleventh banking office opened in October 2016 in Sunbury, also in central Ohio, in Delaware County. It also has a loan production office in Mentor, in Lake County. The Middlefield Banking Company’s northeast Ohio market adjoins the market of Liberty, which is to the immediate west.

Lending–Loan Portfolio Composition and Activity. The Middlefield Banking Company makes residential and commercial mortgage, home equity, secured and unsecured consumer installment, commercial and industrial, and real estate construction loans for owner-occupied and rental properties. The Credit Policy aspires to a loan composition mix consisting of approximately 40% to 50% consumer purpose transactions including residential real estate loans, home equity loans and other consumer loans. The Policy is also designed to provide for 35% to 40% of total loans as business purpose commercial loans and business and consumer credit card accounts of up to 5% of total loans.

Although Ohio law imposes no material restrictions on the types of loans The Middlefield Banking Company may make, real estate-based lending has historically been the primary focus. For prudential reasons,

we avoid lending on the security of real estate located outside our market area. Ohio law does restrict the amount of loans an Ohio-chartered bank may make, generally limiting credit to any single borrower to less than 15% of capital. An additional margin of 10% of capital is allowed for loans fully secured by readily marketable collateral. This 15% legal lending limit has not been a material restriction on lending. We can accommodate loan volumes exceeding the legal lending limit by selling loan participations to other banks. As of September 30, 2016, The Middlefield Banking Company’s 15%-of-capital limit on loans to a single borrower was approximately $11.2 million.

The Middlefield Banking Company offers specialized loans for business and commercial customers, including equipment and inventory financing, real estate construction loans and Small Business Administration loans for qualified businesses. A substantial portion of The Middlefield Banking Company’s commercial loans are designated as real estate loans for regulatory reporting purposes because they are secured by mortgages on real property. Loans of that type may be made for purposes of financing commercial activities, such as accounts receivable, equipment purchases and leasing, but they are secured by real estate to provide The Middlefield Banking Company with an extra measure of security. Although these loans might be secured in whole or in part by real estate, they are treated in the discussions to follow as commercial and industrial loans. The Middlefield Banking Company’s consumer installment loans include secured and unsecured loans to individual borrowers for a variety of purposes, including personal, home improvements, revolving credit lines, autos, boats, and recreational vehicles.

The following table shows on a consolidated basis the composition of the loan portfolio in dollar amounts and in percentages along with a reconciliation to loans receivable, net.

The following table presents consolidated maturity information for the loan portfolio. The table does not include prepayments or scheduled principal repayments. All loans are shown as maturing based on contractual maturities.

Loans due on demand and overdrafts are included in the amount due in one year or less. The Middlefield Banking Company has no loans without a stated schedule of repayment or a stated maturity.

The following table shows on a consolidated basis the dollar amount of all loans due after September 30, 2016 that have pre-determined interest rates and the dollar amount of all loans due after September 30, 2016 that have floating or adjustable rates.

Residential Mortgage LoansA significant portion of The Middlefield Banking Company’s lending consists of origination of conventional loans secured by 1-4 family real estate. Residential mortgage loans approximated $232.5 million or 43.6% of The Middlefield Banking Company’s total loan portfolio at December 31, 2015, and $259.0 million or 44.2% at September 30, 2016.

The Middlefield Banking Company makes loans of up to 80% of the value of the real estate and improvements securing a loan (“LTV” ratio) on 1-4 family real estate. The Middlefield Banking Company generally does not lend in excess of the lower of 80% of the appraised value or sales price of the property. The Middlefield Banking Company offers residential real estate loans with terms of up to 30 years.

Approximately 94.9% of the portfolio of conventional mortgage loans secured by 1-4 family real estate at December 31, 2015 is adjustable rate, and 94.5% at September 30, 2016. Generally, The Middlefield Banking Company originates fixed-rate, single-family mortgage loans in conformity with Freddie Mac guidelines, so as to permit their being sold to Freddie Mac. These loans are sold with servicing rights retained, and are sold in furtherance of The Middlefield Banking Company’s goal of better matching the maturities and interest rate sensitivity of its assets and liabilities. The Middlefield Banking Company generally retains responsibility for collecting and remitting loan payments, inspecting the properties, making certain insurance and tax payments on behalf of borrowers and otherwise servicing the loans it sells and receives a fee for performing these services. Sales of loans also provide funds for additional lending and other purposes.

The Middlefield Banking Company’s home equity Credit Policy generally allows for a loan of up to 85% of a property’s appraised value, less the principal balance of the outstanding first mortgage loan. The Middlefield Banking Company’s home equity loans generally have terms of 20 years.

At December 31, 2015, residential mortgage loans of approximately $4.1 million were over 90 days delinquent or nonaccruing on that date, representing 1.8% of the residential mortgage loan portfolio. At December 31, 2014, residential mortgage loans of approximately $5.3 million were over 90 days delinquent or nonaccruing on that date, representing 2.3% of the residential mortgage loan portfolio. At September 30, 2016, residential mortgage loans of approximately $3.8 million were over 90 days delinquent or nonaccruing on that date, representing 1.5% of the residential mortgage loan portfolio.

Commercial and Industrial Loans and Commercial Real Estate Loans.The Middlefield Banking Company’s commercial loan services include:

Commercial real estate loans include commercial properties occupied by the proprietor of the business conducted on the premises, and income-producing or farm properties. Although The Middlefield Banking Company makes agricultural loans, it currently does not have a significant amount of agricultural loans. The primary risks of commercial real estate loans are loss of income of the owner or occupier of the property and the inability of the market to sustain rent levels. Although commercial and commercial real estate loans generally bear more risk than single-family residential mortgage loans, they tend to be higher yielding, have shorter terms and provide for interest-rate adjustments. Accordingly, commercial and commercial real estate loans enhance a lender’s interest rate risk management and, in management’s opinion, promote more rapid asset and income growth than a loan portfolio composed strictly of residential real estate mortgage loans.

Although a risk of nonpayment exists for all loans, certain specific risks are associated with various kinds of loans. One of the primary risks associated with commercial loans is the possibility that the commercial borrower will not generate income sufficient to repay the loan. The Middlefield Banking Company’s Credit Policy provides that commercial loan applications must be supported by documentation indicating cash flow sufficient for the borrower to service the proposed loan. Financial statements or tax returns for at least three years must be submitted, and annual reviews are required for business purpose relationships of $1,000,000 or more. Ongoing financial information is generally required for any commercial credit where the exposure is $250,000 or more.

The fair value of collateral for collateralized commercial loans must exceed The Middlefield Banking Company’s exposure. For this purpose fair value is determined by independent appraisal or by the loan officer’s estimate employing guidelines established by the Credit Policy. Loans not secured by real estate generally have terms of five years or fewer, unless guaranteed by the U.S. Small Business Administration or other governmental agency, and term loans secured by collateral having a useful life exceeding five years may have longer terms. The Middlefield Banking Company’s Credit Policy allows for terms of up to 15 years for loans secured by commercial real estate, and one year for business lines of credit. The maximum LTV ratio for commercial real estate loans is 80% of the appraised value or cost, whichever is less.

Real estate is commonly a material component of collateral for The Middlefield Banking Company’s loans, including commercial loans. Although the expected source of repayment is generally the operations of the borrower’s business or personal income, real estate collateral provides an additional measure of security. Risks associated with loans secured by real estate include fluctuating land values, changing local economic conditions, changes in tax policies, and a concentration of loans within a limited geographic area.

At December 31, 2015 commercial and commercial real estate loans totaled $274.2 million, or 51.4% of The Middlefield Banking Company’s total loan portfolio. At December 31, 2015, commercial and commercial real estate loans of approximately $3.3 million were over 90 days delinquent or nonaccruing on that date, and represented 1.2% of the commercial and commercial real estate loan portfolios. At December 31, 2014, commercial and commercial real estate loans totaled $225.6 million, or 47.9% of The Middlefield Banking Company’s total loan portfolio. At December 31, 2014, commercial and commercial real estate loans of approximately $1.4 million were over 90 days delinquent or nonaccruing on that date, and represented 0.6% of the commercial and commercial real estate loan portfolios. At September 30, 2016, commercial and commercial real estate loans totaled $305.0 million, or 52.0% of The Middlefield Banking Company’s total loan portfolio. At September 30, 2016, commercial and commercial real estate loans of approximately $2.7 million were over 90 days delinquent or nonaccruing on that date, and represented 0.9% of the commercial and commercial real estate loan portfolios.

Real Estate Construction. The Middlefield Banking Company originates several different types of loans that it categorizes as construction loans, including:

Because of the complex nature of construction lending, these loans are generally recognized as having a higher degree of risk than other forms of real estate lending. The Middlefield Banking Company’s fixed-rate and adjustable-rate construction loans do not provide for the same interest rate terms on the construction loan and on the permanent mortgage loan that follows completion of the construction phase of the loan. It is the norm for The Middlefield Banking Company to make residential construction loans without an existing written commitment for permanent financing. The Middlefield Banking Company’s Credit Policy provides that The Middlefield Banking Company may make construction loans with terms of up to one year, with a maximum LTV ratio for residential construction of 80%. The Middlefield Banking Company also offers residential construction-to-permanent loans that have a twelve-month construction period followed by 30 years of permanent financing.

At December 31, 2015, real estate construction loans totaled $22.1 million, or 4.1% of The Middlefield Banking Company’s total loan portfolio. Real estate construction loans of approximately $0.1 million were over 90 days delinquent or nonaccruing on that date, representing 0.6% of the real estate construction loan portfolio. At December 31, 2014, real estate construction loans totaled $30.3 million, or 6.4% of The Middlefield Banking Company’s total loan portfolio. Real estate construction loans of approximately $0.6 million were over 90 days delinquent or nonaccruing on that date, representing 1.9% of the real estate construction loan portfolio. At September 30, 2016, real estate construction loans totaled $17.6 million, or 3.0% of The Middlefield Banking Company’s total loan portfolio. Real estate construction loans of approximately $17,000 were over 90 days delinquent or nonaccruing on that date, representing .01% of the real estate construction loan portfolio.

Consumer Installment Loans The Middlefield Banking Company’s consumer installment loans include secured and unsecured loans to individual borrowers for a variety of purposes, including personal, home improvement, revolving credit lines, autos, boats, and recreational vehicles. The Middlefield Banking Company does not currently do any indirect lending. Unsecured consumer loans carry significantly higher interest rates than secured loans. The Middlefield Banking Company maintains a higher loan loss allowance for consumer loans, while maintaining strict credit guidelines when considering consumer loan applications.

According to the Credit Policy, consumer loans secured by collateral other than real estate generally may have terms of up to five years, and unsecured consumer loans may have terms up to three years. Real estate security generally is required for consumer loans having terms exceeding five years.

At December 31, 2015, The Middlefield Banking Company had approximately $4.9 million in its consumer installment loan portfolio, representing 0.9% of total loans. At December 31, 2015, 6.2% of consumer installment loans were over 90 days delinquent or nonaccruing. At December 31, 2014, The Middlefield Banking Company had approximately $4.6 million in its consumer installment loan portfolio, representing 1.0% of total loans. At December 31, 2014, 0.1% of consumer installment loans were over 90 days delinquent or nonaccruing. At September 30, 2016, The Middlefield Banking Company had approximately $4.7 million in its consumer installment loan portfolio, representing .80% of total loans. At September 30, 2016, 0.0% of consumer installment loans were over 90 days delinquent or nonaccruing.

Loan Solicitation and Processing Loan originations are developed from a number of sources, including continuing business with depositors, other borrowers and real estate builders, solicitations by Bank personnel and walk-in customers.

When a loan request is made, The Middlefield Banking Company reviews the application, credit bureau reports, property appraisals or evaluations, financial information, verifications of income, and other documentation concerning the creditworthiness of the borrower, as applicable to each loan type. The Middlefield Banking Company’s underwriting guidelines are set by senior management and approved by the Board of Directors. The Credit Policy specifies each individual officer’s loan approval authority. Loans exceeding an individual officer’s approval authority are submitted to an Officer’s Loan Committee, which has authority to approve loans up to $2,000,000. The Board of Directors’ Loan Committee acts as an approval authority for exposures over $2,000,000 and up to $5,000,000. Loans exceeding $5,000,000 require approval from the full Board of Directors.

Income from Lending Activities The Middlefield Banking Company earns interest and fee income from its lending activities. Net of origination costs, loan origination fees are amortized over the life of a loan. The Middlefield Banking Company also receives loan fees related to existing loans, including late charges. Income from loan origination and commitment fees and discounts varies with the volume and type of loans and commitments made and with competitive and economic conditions. Note 1 to the Consolidated Financial Statements included herein contains a discussion of the manner in which loan fees and income are recognized for financial reporting purposes.

Mortgage Banking ActivityThe Middlefield Banking Company originates conventional loans secured by first lien mortgages on one-to-four family residential properties located within its market area for either portfolio or sale into the secondary market. During the year ended December 31, 2015, The Middlefield Banking Company recorded gains of $0.3 million on the sale of $17.6 million in loans receivable originated for sale. During the year ended December 31, 2014, The Middlefield Banking Company recorded gains of $0.2 million on the sale of $6.0 million in loans receivable originated for sale. For the nine months ended September 30, 2016, The Middlefield Banking Company recorded gains of $0.3 on the sale of $16.0 million in loans receivable originated for sale. The sold loans were sold on a servicing retained basis to Freddie Mac.

In addition to interest earned on loans and income recognized on the sale of loans, The Middlefield Banking Company receives fees for servicing loans that it has sold. Because The Middlefield Banking Company has data processing capacity that will allow it to expand its portfolio of serviced loans without incurring significant incremental expenses, The Middlefield Banking Company intends in the future to augment its portfolio of loans serviced by continuing to originate and sell such fixed-rate single-family residential mortgage loans with Freddie Mac while retaining servicing.

Income from these activities will vary from period to period with the volume and type of loans originated and sold, which in turn is dependent on prevailing mortgage interest rates and their effect on the demand for loans in The Middlefield Banking Company’s market area.

Nonperforming Loans Late charges on residential mortgages and consumer loans are assessed if a payment is not received by the due date plus a grace period. When an advanced stage of delinquency appears on a single-family loan and if repayment cannot be expected within a reasonable time or a repayment agreement is not entered into, a required notice of foreclosure or repossession proceedings may be prepared by The Middlefield Banking Company’s attorney and delivered to the borrower so that foreclosure proceedings may be initiated promptly, if necessary. The Middlefield Banking Company also collects late charges on commercial loans.

When The Middlefield Banking Company acquires real estate through foreclosure, voluntary deed, or similar means, it is classified as OREO until it is sold. When property is acquired in this manner, it is recorded at the lower of cost (the unpaid principal balance at the date of acquisition) or fair value, less anticipated cost to sell. Any subsequent write-down is charged to expense. All costs incurred from the date of acquisition to maintain the property are expensed. OREO is appraised during the foreclosure process, before acquisition when possible. Losses are recognized for the amount by which the book value of the related mortgage loan exceeds the estimated net realizable value of the property.

The Middlefield Banking Company undertakes regular review of the loan portfolio to assess its risks, particularly the risks associated with the commercial loan portfolio.

Classified Assets FDIC regulations governing classification of assets require nonmember commercial banks – including The Middlefield Banking Company – to classify their own assets and to establish appropriate general and specific allowances for losses, subject to FDIC review. The regulations are designed to encourage management to evaluate assets on a case-by-case basis, discouraging automatic classifications. Under this classification system, problem assets of insured institutions are classified as “substandard,” “doubtful,” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets include those characterized by the distinct possibility that the insured institution will sustain some loss if the deficiencies are not corrected. Assets classified as “doubtful” have all the weaknesses inherent in those classified substandard, with the added characteristic that the weaknesses make collection of principal in full – on the basis of currently existing facts, conditions, and values – highly questionable and improbable. Assets classified as “loss” are those considered uncollectible and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. Assets that do not expose The Middlefield Banking Company to risk sufficient to warrant classification in one of the above categories, but that possess some weakness, are required to be designated “special mention” by management.

When an insured institution classifies assets as either “substandard” or “doubtful,” it may establish allowances for loan losses in an amount deemed prudent by management. When an insured institution classifies assets as “loss,” it is required either to establish an allowance for losses equal to 100% of that portion of the assets so classified or to charge off that amount. An Ohio nonmember bank’s determination about classification of its assets and the amount of its allowances is subject to review by the FDIC, which may order the establishment of additional loss allowances. Management also employs an independent third party to semi-annually review and validate the internal loan review process and loan classifications.

The Middlefield Banking Company experienced a decrease in substandard loans as of December 31, 2015. Loans secured by residential real estate and commercial real estate account for $5.8 million and $8.0 million of the substandard loans, respectively. These amounts represent 88.8% of The Middlefield Banking Company’s substandard loans. As of September 30, 2016 and December 31, 2015, 2014, 2013, 2012, and 2011, consolidated classified loans were as follows:

Other than those disclosed above, The Middlefield Banking Company does not believe there are any loans classified for regulatory purposes as loss, doubtful, substandard, special mention or otherwise, which will result in losses or have a material impact on future operations, liquidity or capital reserves. We are not aware of any other information that causes us to have serious doubts as to the ability of borrowers in general to comply with repayment terms.

Investments Investment securities provide a return on residual funds after lending activities. Investments may be in federal funds sold, corporate securities, U.S. Government and agency obligations, state and local government obligations and government-guaranteed mortgage-backed securities. The Middlefield Banking

Company generally does not invest in securities that are rated less than investment grade by a nationally recognized statistical rating organization. Ohio law prescribes the kinds of investments an Ohio-chartered bank may make. Permitted investments include local, state, and federal government securities, mortgage-backed securities, and securities of federal government agencies. An Ohio-chartered bank also may invest up to 10% of its assets in corporate debt and equity securities, or a higher percentage in certain circumstances. Ohio law also limits to 15% of capital the amount an Ohio-chartered bank may invest in the securities of any one issuer, other than local, state, and federal government and federal government agency issuers and mortgage-backed securities issuers. These provisions have not been a material constraint upon The Middlefield Banking Company’s investment activities.

All securities-related activity is reported to The Middlefield Banking Company’s board of directors. General changes in investment strategy are required to be reviewed and approved by the board. Senior management can purchase and sell securities in accordance with The Middlefield Banking Company’s stated investment policy.

Management determines the appropriate classification of securities at the time of purchase. At this time The Middlefield Banking Company has no securities that are classified as held to maturity. Securities to be held for indefinite periods and not intended to be held to maturity or on a long-term basis are classified as available for sale. Available-for-sale securities are reflected on the balance sheet at their fair value.

The following table exhibits the consolidated amortized cost and fair value of The Middlefield Banking Company’s investment portfolio at September 30, 2016 and at December 31, 2013, 2014, and 2015:

The contractual maturity of investment debt securities as of September 30, 2016 is as follows:

Expected maturities of investment securities could differ from contractual maturities because the borrower, or issuer, could have the right to call or prepay obligations with or without call or prepayment penalties. The average yields in the above table are not calculated on a tax-equivalent basis.

As of September 30, 2016, The Middlefield Banking Company also held 18,872 shares of $100 par value Federal Home Loan Bank of Cincinnati stock, which is a restricted security. FHLB stock represents an equity interest in the FHLB, but it does not have a readily determinable market value. The stock can be sold at its par value only, and only to the FHLB or to another member institution. Member institutions are required to maintain a minimum stock investment in the FHLB, based on total assets, total mortgages, and total mortgage-backed securities. The Middlefield Banking Company’s minimum investment in FHLB stock at September 30, 2016 was $1.9 million.

Sources of Funds–Deposit Accounts Deposit accounts are a major source of funds for The Middlefield Banking Company. The Middlefield Banking Company offers a number of deposit products to attract both commercial and regular consumer checking and savings customers, including regular and money market savings accounts, NOW accounts, and a variety of fixed-maturity, fixed-rate certificates with maturities ranging from 3 to 60 months. These accounts earn interest at rates established by management based on competitive market factors and management’s desire to increase certain types or maturities of deposit liabilities. The Middlefield Banking Company also provides travelers’ checks, official checks, money orders, ATM services, and IRA accounts.

The following table shows on a consolidated basis the amount of time deposits of $100,000 or more as of September 30, 2016, including certificates of deposit, by time remaining until maturity.

BorrowingsDeposits and repayment of loan principal are The Middlefield Banking Company’s primary sources of funds for lending activities and other general business purposes. However, when the supply of funds cannot satisfy the demand for loans or general business purposes, The Middlefield Banking Company’s subsidiary bank can obtain funds from the FHLB of Cincinnati. Interest and principal are payable monthly, and the line of credit is secured by a pledge collateral agreement. At September 30, 2016, The Middlefield Banking Company had $31.5 million of FHLB borrowings outstanding. The Middlefield Banking Company also has access to credit through the Federal Reserve Bank of Cleveland and other funding sources.

The outstanding balances and related information about short-term borrowings as of September 30, 2016 and December 31, 2015, which includes securities sold under agreements to repurchase, lines of credit with other banks and Federal Funds purchased are summarized on a consolidated basis as follows:

Personnel. As of September 30, 2016 The Middlefield Banking Company had 140 full-time equivalent employees. No employees are represented by a collective bargaining group. Management considers relations with employees to be excellent.

Supervision and Regulation. The following discussion of bank supervision and regulation is qualified in its entirety by reference to the statutory and regulatory provisions discussed. Changes in applicable law or in the policies of various regulatory authorities could materially affect the business and prospects of Middlefield. Middlefield is a bank holding company within the meaning of the Bank Holding Company Act of 1956. As such, Middlefield is subject to regulation, supervision, and examination by the Board of Governors of the Federal Reserve System, acting primarily through the Federal Reserve Bank of Cleveland. Middlefield is required to file annual reports and other information with the Federal Reserve. The Middlefield Banking Company subsidiary is an Ohio-chartered commercial bank. As a state-chartered, nonmember bank, The Middlefield Banking Company is primarily regulated by the FDIC and by the Ohio Division of Financial Institutions.

Middlefield and The Middlefield Banking Company are subject to federal banking laws, and Middlefield is also subject to Ohio bank law. These federal and state laws are intended to protect depositors, not stockholders. Federal and state laws applicable to holding companies and their financial institution subsidiaries regulate the range of permissible business activities, investments, reserves against deposits, capital levels, lending activities and practices, the nature and amount of collateral for loans, establishment of branches, mergers, dividends, and a variety of other important matters. The Middlefield Banking Company is subject to detailed, complex, and sometimes overlapping federal and state statutes and regulations affecting routine banking operations. These statutes and regulations include but are not limited to state usury and consumer credit laws, the Truth-in-Lending Act and Regulation Z, the Equal Credit Opportunity Act and Regulation B, the Fair Credit Reporting Act, the Truth in Savings Act, and the Community Reinvestment Act. The Middlefield Banking Company must comply with Federal Reserve Board regulations requiring depository institutions to maintain reserves against their transaction accounts (principally NOW and regular checking accounts). Because required reserves are commonly maintained in the form of vault cash or in a noninterest-bearing account (or pass-through account) at a Federal Reserve Bank, the effect of the reserve requirement is to reduce an institution’s earning assets.

The Federal Reserve Board and the FDIC have extensive authority to prevent and to remedy unsafe and unsound practices and violations of applicable laws and regulations by institutions and holding companies. The agencies may assess civil money penalties, issue cease-and-desist or removal orders, seek injunctions, and publicly disclose those actions. In addition, the Ohio Division of Financial Institutions possesses enforcement powers to address violations of Ohio banking law by Ohio-chartered banks.

Regulation of Bank Holding Companies–Bank and Bank Holding Company Acquisitions The Bank Holding Company Act requires every bank holding company to obtain approval of the Federal Reserve before –

The Federal Reserve will not approve an acquisition, merger, or consolidation that would have a substantially anticompetitive result, unless the anticompetitive effects of the proposed transaction are clearly outweighed by a greater public interest in satisfying the convenience and needs of the community to be served. The Federal Reserve also considers capital adequacy and other financial and managerial factors and the record of performance under the Community Reinvestment Act in its review of acquisitions and mergers.

Additionally, the Bank Holding Company Act, the Change in Bank Control Act and the Federal Reserve Board’s Regulation Y require advance approval of the Federal Reserve to acquire “control” of a bank holding

company. Control is conclusively presumed to exist if an individual or company acquires 25% or more of a class of voting securities. If the holding company has securities registered under Section 12 of the Securities Exchange Act of 1934, as Middlefield does, or if no other person owns a greater percentage of the class of voting securities, control is presumed to exist if a person acquires 10% or more, but less than 25%, of any class of voting securities. Approval of the Ohio Division of Financial Institutions is also necessary to acquire control of an Ohio-chartered bank.

Nonbanking Activities With some exceptions, the Bank Holding Company Act generally prohibits a bank holding company from acquiring or retaining direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank or bank holding company, or from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries. The principal exceptions to these prohibitions involve nonbank activities that, by statute or by Federal Reserve Board regulation or order, are held to be closely related to the business of banking or of managing or controlling banks. In making its determination that a particular activity is closely related to the business of banking, the Federal Reserve considers whether the performance of the activities by a bank holding company can be expected to produce benefits to the public – such as greater convenience, increased competition, or gains in efficiency in resources – that will outweigh the risks of possible adverse effects such as decreased or unfair competition, conflicts of interest, or unsound banking practices. Some of the activities determined by Federal Reserve Board regulation to be closely related to the business of banking are: making or servicing loans or leases; engaging in insurance and discount brokerage activities; owning thrift institutions; performing data processing services; acting as a fiduciary or investment or financial advisor; and making investments in corporations or projects designed primarily to promote community welfare.

Financial Holding Companies On November 12, 1999 the Gramm-Leach-Bliley Act became law, repealing much of the 1933 Glass-Steagall Act’s separation of the commercial and investment banking industries. The Gramm-Leach-Bliley Act expands the range of nonbanking activities a bank holding company may engage in, while preserving existing authority for bank holding companies to engage in activities that are closely related to banking. The new legislation creates a new category of holding company called a “financial holding company.” Financial holding companies may engage in any activity that is –

The Federal Reserve Board and the Secretary of the Treasury have authority to decide that other activities are also financial in nature or incidental to financial activity, taking into account changes in technology, changes in the banking marketplace, competition for banking services, and so on. Middlefield is engaged solely in activities that were permissible for a bank holding company before enactment of the Gramm-Leach-Bliley Act. Federal Reserve Board rules require that all of the depository institution subsidiaries of a financial holding company be and remain well capitalized and well managed. If all depository institution subsidiaries of a financial holding company do not remain well capitalized and well managed, the financial holding company must enter into an agreement acceptable to the Federal Reserve Board, undertaking to comply with all capital and management requirements within 180 days. In the meantime the financial holding company may not use its expanded authority to engage in nonbanking activities without Federal Reserve Board approval and the Federal Reserve may impose other limitations on the holding company’s or affiliates’ activities. If a financial holding company fails to restore the well-capitalized and well-managed status of a depository institution subsidiary, the Federal Reserve may order divestiture of the subsidiary.

Holding Company Capital and Source of Strength The Federal Reserve considers the adequacy of a bank holding company’s capital on essentially the same risk-adjusted basis as capital adequacy is determined by the FDIC at the bank subsidiary level. The Federal Deposit Insurance Act requires that bank holding companies serve as a source of strength for their subsidiary banking institutions.

Under Bank Holding Company Act section 5(e), the Federal Reserve Board may require a bank holding company to terminate any activity or relinquish control of a nonbank subsidiary if the Federal Reserve Board determines that the activity or control constitutes a serious risk to the financial safety, soundness or stability of a subsidiary bank. And with the Federal Deposit Insurance Corporation Improvement Act of 1991’s addition of the prompt corrective action provisions to the Federal Deposit Insurance Act, section 38(f)(2)(I) of the Federal Deposit Insurance Act now provides that a federal bank regulatory authority may require a bank holding company to divest itself of an undercapitalized bank subsidiary if the agency determines that divestiture will improve the subsidiary bank’s financial condition and prospects.

Capital –Risk-Based Capital Requirements The Federal Reserve Board and the FDIC employ similar risk-based capital guidelines in their examination and regulation of bank holding companies and financial institutions. If capital falls below the minimum levels established by the guidelines, the holding company or bank may be denied approval to acquire or establish additional banks or nonbank businesses or to open new facilities. Failure to satisfy capital guidelines could subject a banking institution to a variety of restrictions or enforcement actions by federal bank regulatory authorities, including the termination of deposit insurance by the FDIC and a prohibition on the acceptance of brokered deposits.

A bank’s capital hedges its risk exposure, absorbing losses that can be predicted as well as losses that cannot be predicted. According to the Federal Financial Institutions Examination Council’s explanation of the capital component of the Uniform Financial Institutions Rating System, commonly known as the “CAMELS” rating system, a rating system employed by the Federal bank regulatory agencies, a financial institution must “maintain capital commensurate with the nature and extent of risks to the institution and the ability of management to identify, measure, monitor, and control these risks. The effect of credit, market, and other risks on the institution’s financial condition should be considered when evaluating the adequacy of capital.” Under Basel III, a community bank such as The Middlefield Banking Company is required to maintain a minimum common equity Tier 1 capital ratio of 4.5%, a Tier 1 capital ratio of 6%, a total capital ratio of 8%, and a Tier 1 leverage ratio of 4%. Basel III also established a “capital conservation buffer” of 2.5% above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital and will be phased in beginning in January 2016 at 0.625% of risk-weighted assets and increase by that amount each year until fully implemented in January 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions that fail to maintain the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. These ratios are absolute minimums. In practice, banks are expected to operate with more than the absolute minimum capital. The FDIC may establish greater minimum capital requirements for specific institutions.

The FDIC also employs a market risk component in its calculation of capital requirements for nonmember banks. The market risk component could require additional capital for general or specific market risk of trading portfolios of debt and equity securities and other investments or assets. The FDIC’s evaluation of an institution’s capital adequacy takes account of a variety of other factors as well, including interest rate risks to which the institution is subject, the level and quality of an institution’s earnings, loan and investment portfolio characteristics and risks, risks arising from the conduct of nontraditional activities, and a variety of other factors.

Accordingly, the FDIC’s final supervisory judgment concerning an institution’s capital adequacy could differ significantly from the conclusions that might be derived from the absolute level of an institution’s risk-based capital ratios. Therefore, institutions generally are expected to maintain risk-based capital ratios that exceed the minimum ratios discussed above. This is particularly true for institutions contemplating significant expansion plans and institutions that are subject to high or inordinate levels of risk. Moreover, although the FDIC

does not impose explicit capital requirements on holding companies of institutions regulated by the FDIC, the FDIC can take account of the degree of leverage and risks at the holding company level. If the FDIC determines that the holding company (or another affiliate of the institution regulated by the FDIC) has an excessive degree of leverage or is subject to inordinate risks, the FDIC may require the subsidiary institution(s) to maintain additional capital or the FDIC may impose limitations on the subsidiary institution’s ability to support its weaker affiliates or holding company.

At December 31, 2015 and September 30, 2016, Middlefield and The Middlefield Banking Company were in compliance with all regulatory capital requirements.

Prompt Corrective Action. To resolve the problems of undercapitalized institutions and to prevent a recurrence of savings and loan crisis of the 1980s and early 1990s, the Federal Deposit Insurance Corporation Improvement Act of 1991 established a system known as “prompt corrective action.” Under the prompt corrective action provisions and implementing regulations, every institution is classified into one of five categories, depending on its total risk-based capital ratio, its common equity Tier 1 ratio, its Tier 1 risk-based capital ratio, its leverage ratio, and subjective factors. The categories are “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.” To be considered well capitalized for purposes of the prompt corrective action rules, a bank must maintain total risk-based capital of 10.0% or greater, Tier 1 risk-based capital of 8.0% or greater, common equity Tier 1 capital of 6.5%, and a leverage ratio of 5.0% or greater. An institution with a capital level that might qualify for well capitalized or adequately capitalized status may nevertheless be treated as though it were in the next lower capital category if its primary federal banking supervisory authority determines that an unsafe or unsound condition or practice warrants that treatment.

A financial institution’s operations can be significantly affected by its capital classification under the prompt corrective action rules. For example, an institution that is not well capitalized generally is prohibited from accepting brokered deposits and offering interest rates on deposits higher than the prevailing rate in its market without advance regulatory approval, which can have an adverse effect on the bank’s liquidity. At each successively lower capital category, an insured depository institution is subject to additional restrictions. Undercapitalized institutions are required to take specified actions to increase their capital or otherwise decrease the risks to the federal deposit insurance funds. A bank holding company must guarantee that a subsidiary bank that adopts a capital restoration plan will satisfy its plan obligations. Any capital loans made by a bank holding company to a subsidiary bank are subordinated to the claims of depositors in the subsidiary bank and to certain other indebtedness of the subsidiary bank. If bankruptcy of a bank holding company occurs, any commitment by the holding company to a Federal banking regulatory agency to maintain the capital of a subsidiary bank would be assumed by bankruptcy trustee and would be entitled to priority of payment. Bank regulatory agencies generally are required to appoint a receiver or conservator shortly after an institution becomes critically undercapitalized.

The Middlefield Banking Company met each of the well-capitalized ratio guidelines at September 30, 2016. The following table indicates the capital ratios for The Middlefield Banking Company and Middlefield at September 30, 2016 and December 31, 2015. The capital conservation buffer is being phased in from 0.625% for 2016 to 2.50% by 2019. The amounts shown below as the adequately capitalized ratio plus capital conservation buffer includes the fully phased-in 2.50% buffer.

New Capital Rules On July 9, 2013, the federal bank regulatory agencies issued a final rule that will revise their risk-based capital requirements and the method for calculating risk-weighted assets to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act. The final rule applies to all depository institutions, top-tier bank holding companies with total consolidated assets of $1.0 billion or more and top-tier savings and loan holding companies. The rule establishes a new common equity Tier 1 minimum capital requirement (4.5% of risk-weighted assets), increases the minimum Tier 1 capital to risk-based assets requirement (from 4.0% to 6.0% of risk-weighted assets) and assigns a higher risk weight (150%) to exposures that are more than 90 days past due or are on nonaccrual status and to certain commercial real estate facilities that finance the acquisition, development or construction of real property.

The rule also includes changes in what constitutes regulatory capital, some of which are subject to a two-year transition period. These changes include the phasing-out of certain instruments as qualifying capital. In addition, Tier 2 capital is no longer limited to the amount of Tier 1 capital included in total capital. Mortgage servicing rights, certain deferred tax assets and investments in unconsolidated subsidiaries over designated percentages of common stock will be required to be deducted from capital, subject to a two-year transition period. Finally, Tier 1 capital will include accumulated other comprehensive income (which includes all unrealized gains and losses on available-for-sale debt and equity securities), subject to a two-year transition period. In the first quarter of 2015 Middlefield permanently opted out of the inclusion of accumulated other comprehensive income in its capital calculation in an effort to reduce the impact of market volatility on its regulatory capital levels.

The new capital requirements also include changes in the risk-weights of assets to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and nonresidential mortgage loans that are 90 day past due or otherwise on nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (up from 100%) for mortgage servicing and deferred tax assets that are not deducted from capital; and increased risk-weights (from 0% to up to 600%) for equity exposures.

Finally, the rule limits capital distributions and certain discretionary bonus payments if the bank does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets in addition to the amount necessary to meet its minimum risk-based capital requirements.

The final rule became effective for The Middlefield Banking Company on January 1, 2015. The capital conservation buffer requirement will be phased in beginning January 1, 2016 at 0.625% of risk-weighted assets increasing each year until fully implemented at 2.5% on January 1, 2019.

Limits on Dividends and Other Payments Middlefield’s ability to obtain funds for the payment of dividends and for other cash requirements depends on the amount of dividends that may be paid to it by The Middlefield Banking Company. Ohio bank law and FDIC policy are consistent, providing that banks generally may rely solely on current earnings for the payment of dividends. Under Ohio Revised Code section 1107.15(B) a dividend may be declared from surplus, meaning additional paid-in capital, with the approval of (x) the Ohio Superintendent of Financial Institutions and (y) the holders of two thirds of the bank’s outstanding shares. Superintendent approval is also necessary for payment of a dividend if the total of all cash dividends in a year exceeds the sum of (x) net income for the year and (y) retained net income for the two preceding years. Relying on 12 U.S.C. 1818(b), the FDIC may restrict a bank’s ability to pay a dividend if the FDIC has reasonable cause to believe that the dividend would constitute an unsafe and unsound practice. A bank’s ability to pay dividends may be affected also by the FDIC’s capital maintenance requirements and prompt corrective action rules. A bank may not pay a dividend if the bank is undercapitalized or if payment would cause the bank to become undercapitalized.

A 1985 policy statement of the Federal Reserve Board declares that a bank holding company should not pay cash dividends on common stock unless the organization’s net income for the past year is sufficient to fully fund the dividends and the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality, and overall financial condition. Until the third anniversary of the January 20, 2014 merger of Emerald Bank into The Middlefield Banking Company, The Middlefield Banking Company cannot pay a dividend to Middlefield Banc Corp. without advance approval of the Ohio Division of Financial Institutions.

The Dodd-Frank Act The Dodd-Frank Wall Street Reform and Consumer Protection Act (“DFA”) became law on July 21, 2010. The DFA includes corporate governance and executive compensation reforms, new registration requirements for hedge fund and private equity fund advisers, increased regulation of over-the-counter derivatives and asset-backed securities, and new rules for credit rating agencies. The DFA includes these provisions –

The DFA creates a new, independent federal agency called the Consumer Financial Protection Bureau (CFPB), which has rulemaking, supervisory, and enforcement powers under specific federal consumer financial protection laws, including the Equal Credit Opportunity Act, Truth in Lending Act, Real Estate Settlement Procedures Act, Fair Credit Reporting Act, Fair Debt Collection Act, and Consumer Financial Privacy provisions of the Gramm-Leach-Bliley Act. In addition to giving the CFPB responsibility for these specific statutes, the DFA grants to the CFPB broad authority to prohibit the offering by banks of consumer financial products or engaging in acts or practices that the CFPB considers to be unfair, deceptive, or abusive. The CFPB has examination and primary enforcement authority over depository institutions with $10 billion or more in assets, not smaller institutions. However, smaller institutions are subject to CFPB rules. In addition, the standards established by the CFPB for large institutions are likely to be applied in practice to smaller institutions as well. The DFA does not prevent states from adopting consumer protection laws and standards that are more stringent than those adopted at the federal level and, in certain circumstances, permits state attorneys general to enforce compliance with both the state and federal laws and regulations.

Implementing section 1411 of the DFA, in 2013 the CFPB amended Regulation Z under the Truth in Lending Act, adding a rule that mortgage lenders must make a reasonable and good faith determination that a consumer being granted mortgage credit has the ability to repay the loan according to its terms. Under this new rule, referred to as the “ability-to-repay” rule, mortgage lenders may determine the consumer’s ability to repay in one of two ways. The first alternative involves assessment of eight underwriting factors, including the loan applicant’s current or reasonably expected income or assets, current employment status, monthly payment for the credit applied for, monthly payment on any simultaneous loan being made to the applicant, monthly payment for mortgage-related obligations, current debt obligations, alimony, and child support, monthly debt-to-income ratio or residual income, and credit history. The second alternative involves origination of a so-called “qualified mortgage,” meaning a mortgage with terms that are consistent with minimum standards established by the CFPB, which currently include a maximum 43% debt-to-income ratio for the borrower (although the 43% minimum debt-to-income ratio does not apply if the loan is eligible to be purchased, insured, or guaranteed by FNMA, FHLMC, HUD, or the VA). In general terms, a qualified mortgage is one with a term of 30 years or less, with substantially equal regular periodic payments (although adjustable-rate mortgages can be qualified mortgages), with total points and fees of 3% of the loan amount or less, and without negative amortization or interest-only payments or balloon payments.

A lender originating a qualified mortgage is protected against a legal claim that the lender failed to comply with the ability-to-repay rule. A mortgage with an interest rate exceeding the prime rate by 1.5 percentage points or more (3.5 percentage points for subordinate-lien loans such as home equity loans) is referred to in the CFPB rule as a higher-priced mortgage loan, but is more commonly known as a subprime loan. A subprime loan can be a qualified mortgage, but the lender making a subprime qualified mortgage has less protection under the ability-to-repay rule than a lender making a prime qualified mortgage. A lender originating a mortgage that is not a qualified mortgage is exposed to a potential claim that the lender did not comply with the ability-to-repay rules, which could require the lender to pay damages to the borrower, including but not necessarily limited to the sum of all finance charges and fees paid by the borrower (a lender originating a subprime qualified mortgage bears this risk to a degree as well). The borrower’s claim also could impair the lender’s ability to enforce the loan terms or foreclose on the real estate collateral. Because of these potential risks, a qualified mortgage might have more value in the secondary mortgage market and might be easier for a lender to sell into the secondary mortgage market than a mortgage that is not a qualified mortgage.

Although we believe the majority of our mortgage originations will be qualified mortgages, the ability-to-repay rule creates a new basis for challenge by regulators and by consumers. In addition, the CFPB’s mission is consumer protection, not lender safety and soundness, and for that reason the CFPB wrote the ability-to-repay rule with the goal of preventing consumers from being steered by lenders into expensive and unsustainable borrowing, rather than with the goal of assuring actual loan repayment. Accordingly, typical credit-quality features such as LTV standards are not part of the ability-to-repay rule, and it will not necessarily be the case that qualified mortgages have a higher probability or history of repayment than other mortgages. Compliance with the ability-to-repay rules has increased community banks’ compliance costs, including our own, and will potentially adversely affect the profitability of routine residential mortgage lending. In addition, for the mortgage lending industry the ability-to-repay rule creates a bias in favor of qualified mortgages, which because of factors such as a minimum 43% debt-to-income ratio could have unintended adverse effects, such as reducing community bank lending to low- and moderate-income borrowers and communities.

In addition to ability to repay, the DFA imposes a risk-retention requirement on mortgage lenders selling loans into the secondary mortgage market. With some exceptions, a mortgage lender selling a loan into the secondary mortgage market must retain not less than 5% of the credit risk associated with the loan, the assumption being that if mortgage lenders remain exposed to credit risk they will not knowingly make loans that fail to satisfy ordinary and reasonable standards of creditworthiness. A qualified mortgage for purposes of the ability-to-repay rule is also exempt from the risk-retention requirement, allowing a mortgage lender to sell 100% of a qualified mortgage rather than only 95%. The exemption of qualified mortgages from the risk-retention requirement is likely to contribute to the regulatory bias in favor of qualified mortgages and against other forms of mortgage lending.

Sarbanes-Oxley Act of 2002 The goals of the Sarbanes-Oxley Act enacted in 2002 are to increase corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies, and to protect investors by improving the accuracy and reliability of corporate disclosures made under the securities laws. The changes are intended to allow shareholders to monitor the performance of companies and directors more easily and efficiently.

The Sarbanes-Oxley Act generally applies to all companies that file periodic reports with the SEC under the Securities Exchange Act of 1934. The Act has an impact on a wide variety of corporate governance and disclosure issues, including the composition of audit committees, certification of financial statements by the chief executive officer and the chief financial officer, forfeiture of bonuses and profits made by directors and senior officers in the 12-month period covered by restated financial statements, a prohibition on insider trading during pension plan black-out periods, disclosure of off-balance sheet transactions, a prohibition on personal loans to directors and officers (excluding Federally insured financial institutions), expedited filing requirements for stock transaction reports by officers and directors, the formation of a public accounting oversight board, auditor independence, and various increased criminal penalties for violations of securities laws.

Deposit Insurance The premium that banks pay for deposit insurance is based upon a risk classification system established by the FDIC. Banks with higher levels of capital and a low degree of supervisory concern are assessed lower premiums than banks with lower levels of capital or a higher degree of supervisory concern.

Interstate Banking and Branching Section 613 of the DFA amends the interstate branching provisions of the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994. The expandedde novo branching authority of the DFA authorizes a state or national bank to open ade novobranch in another state if the law of the state where the branch is to be located would permit a state bank chartered by that state to open the branch. Section 607 of the DFA also increases the approval threshold for interstate bank acquisitions, providing that a bank holding company must be well capitalized and well managed as a condition to approval of an interstate bank acquisition, rather than being merely adequately capitalized and adequately managed, and that an acquiring bank must be and remain well capitalized and well managed as a condition to approval of an interstate bank merger.

Transactions with Affiliates Although The Middlefield Banking Company is not a member bank of the Federal Reserve System, it is required by the Federal Deposit Insurance Act to comply with section 23A and section 23B of the Federal Reserve Act – pertaining to transactions with affiliates – as if it were a member bank. These statutes are intended to protect banks from abuse in financial transactions with affiliates, preventing federally insured deposits from being diverted to support the activities of unregulated entities engaged in nonbanking businesses. An affiliate of a bank includes any company or entity that controls or is under common control with the bank. Generally, section 23A and section 23B of the Federal Reserve Act –

The Middlefield Banking Company’s authority to extend credit to insiders – meaning executive officers, directors and greater than 10% stockholders – or to entities those persons control, is subject to section 22(g) and section 22(h) of the Federal Reserve Act and Regulation O of the Federal Reserve Board. Among other things, these laws require insider loans to be made on terms substantially similar to those offered to unaffiliated individuals, place limits on the amount of loans a bank may make to insiders based in part on the bank’s capital position, and require that specified approval procedures be followed. Loans to an individual insider may not exceed the legal limit on loans to any one borrower, which in general terms is 15% of capital but can be higher in some circumstances. And the aggregate of all loans to all insiders may not exceed the bank’s unimpaired capital and surplus. Insider loans exceeding the greater of 5% of capital or $25,000 must be approved in advance by a majority of the board, with any “interested” director not participating in the voting. Lastly, loans to executive officers are subject to special limitations. Executive officers may borrow in unlimited amounts to finance their children’s education or to finance the purchase or improvement of their residence, and they may borrow no more than $100,000 for most other purposes. Loans to executive officers exceeding $100,000 may be allowed if the loan is fully secured by government securities or a segregated deposit account. A violation of these restrictions could result in the assessment of substantial civil monetary penalties, the imposition of a cease-and-desist order or other regulatory sanctions.

Banking agency guidance for commercial real estate lending In December 2006 the FDIC and other Federal banking agencies issued final guidance on sound risk management practices for concentrations in commercial real estate lending, including acquisition and development lending, construction lending, and other land loans, which recent experience has shown can be particularly high-risk lending.

The commercial real estate risk management guidance does not impose rigid limits on commercial real estate lending but does create a much sharper supervisory focus on the risk management practices of banks with concentrations in commercial real estate lending. According to the guidance, an institution that has experienced rapid growth in commercial real estate lending, has notable exposure to a specific type of commercial real estate, or is approaching or exceeds the following supervisory criteria may be identified for further supervisory analysis of the level and nature of its commercial real estate concentration risk –

These measures are intended merely to enable the bank regulatory agencies to quickly identify institutions that could have an excessive commercial real estate lending concentration, potentially requiring close supervision to ensure that the institutions have sound risk management practices in place. Conversely, these measures do not imply that banks are authorized by the December 2006 guidance to accumulate a commercial real estate lending concentration up to the 100% and 300% thresholds.

Corporate Governance and Compensation The Federal banking agencies jointly published their final Guidance on Sound Incentive Compensation Policies in June of 2010. The goal of the guidance is to enable financial organizations to manage the safety and soundness risks of incentive compensation arrangements and to assist banks and bank holding companies with identification of improperly-structured compensation arrangements. To ensure that incentive compensation arrangements do not encourage employees to take excessive risks that undermine safety and soundness, the incentive compensation guidance sets forth these key principles –

To implement the interagency guidance, a financial organization must regularly review incentive compensation arrangements for all executive and non-executive employees who, either individually or as part of a group, have the ability to expose the organization to material amounts of risk, also reviewing the risk-management, control, and corporate governance processes related to these arrangements. The organization must immediately correct any identified deficiencies in compensation arrangements or processes that are inconsistent with safety and soundness.

In addition to numerous provisions that affect the business of banks and bank holding companies, the DFA includes in Title IX a number of provisions affecting corporate governance and executive compensation, for example the requirements that stockholders be given the opportunity to consider and vote upon executive compensation disclosed in a company’s annual meeting proxy statement, that a company’s compensation committee be comprised entirely of independent directors and that the committee have stated minimum authorities, that company policy provide for recovery of excess incentive compensation after an accounting restatement, and that stockholders have the ability to designate director nominees for inclusion in a company’s annual meeting proxy statement. Section 956 also provides for adoption of incentive compensation guidelines jointly by the Federal banking agencies and the SEC, the National Credit Union Administration, and the Federal Housing Finance Agency.

Community Reinvestment Act Under the Community Reinvestment Act of 1977 and implementing regulations of the banking agencies, a financial institution has a continuing and affirmative obligation – consistent with safe and sound operation – to address the credit needs of its entire community, including low- and moderate-income neighborhoods. The CRA does not establish specific lending requirements or programs for financial institutions, nor does it limit an institution’s discretion to develop the types of products and services it believes are best suited to its particular community. The CRA requires that bank regulatory agencies conduct regular CRA examinations and provide written evaluations of institutions’ CRA performance. The CRA also requires that an institution’s CRA performance rating be made public. CRA performance evaluations are based on a four-tiered rating system: Outstanding, Satisfactory, Needs to Improve and Substantial Noncompliance.

Although CRA examinations occur on a regular basis, CRA performance evaluations have been used principally in the evaluation of regulatory applications submitted by an institution. CRA performance evaluations are considered in evaluating applications for such things as mergers, acquisitions, and applications to open branches.

The Middlefield Banking Company’s CRA performance evaluation dated December 2, 2013 assigns a CRA rating of “Satisfactory.”

Federal Home Loan Bank The Federal Home Loan Bank serves as a credit source for their members. As a member of the FHLB of Cincinnati, The Middlefield Banking Company must maintain an investment in the capital stock of the FHLB of Cincinnati in an amount calculated by reference to the amount of loans, and or “advances,” from the FHLB. Each FHLB is required to establish standards of community investment or service that its members must maintain for continued access to long-term advances from the FHLB. The standards take into account a member’s performance under the Community Reinvestment Act and its record of lending to first-time home buyers.

Anti-money laundering and anti-terrorism legislation The Bank Secrecy Act of 1970 requires financial institutions to maintain records and report transactions to prevent the financial institutions from being used to hide money derived from criminal activity and tax evasion. The Bank Secrecy Act establishes (a) record keeping requirements to assist government enforcement agencies with tracing financial transactions and flow of funds, (b) reporting requirements for Suspicious Activity Reports and Currency Transaction Reports to assist government enforcement agencies with detecting patterns of criminal activity, (c) enforcement provisions authorizing criminal and civil penalties for illegal activities and violations of the Bank Secrecy Act and its implementing regulations, and (d) safe harbor provisions that protect financial institutions from civil liability for their cooperative efforts.

The Treasury’s Office of Foreign Asset Control administers and enforces economic and trade sanctions against targeted foreign countries, entities, and individuals based on U.S. foreign policy and national security goals. As a result, financial institutions must scrutinize transactions to ensure that they do not represent obligations of or ownership interests in entities owned or controlled by sanctioned targets.

Signed into law on October 26, 2001, the USA PATRIOT Act of 2001 is omnibus legislation enhancing the powers of domestic law enforcement organizations to resist the international terrorist threat to United States security. Title III of the legislation, the International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001, most directly affects the financial services industry, enhancing the Federal government’s ability to fight money laundering through monitoring of currency transactions and suspicious financial activities. The Act has significant implications for depository institutions and other businesses involved in the transfer of money –

Consumer protection laws and regulations. The Middlefield Banking Company is subject to regular examination by the FDIC to ensure compliance with statutes and regulations applicable to The Middlefield Banking Company’s business, including consumer protection statutes and implementing regulations, some of which are discussed below. Violations of any of these laws may result in fines, reimbursements, and other related penalties.

Equal Credit Opportunity Act. The Equal Credit Opportunity Act generally prohibits discrimination in any credit transaction, whether for consumer or business purposes, on the basis of race, color, religion, national origin, sex, marital status, age (except in limited circumstances), receipt of income from public assistance programs, or good faith exercise of any rights under the Consumer Credit Protection Act.

Truth in Lending Act. The Truth in Lending Act is designed to ensure that credit terms are disclosed in a meaningful way so that consumers may compare credit terms more readily and knowledgeably. As a result of the Truth in Lending Act, all creditors must use the same credit terminology to express rates and payments, including the annual percentage rate, the finance charge, the amount financed, the total of payments and the payment schedule, among other things.

Fair Housing Act. The Fair Housing Act makes it unlawful for a lender to discriminate against any person because of race, color, religion, national origin, sex, handicap, or familial status. A number of lending practices have been held by the courts to be illegal under the Fair Housing Act, including some practices that are not specifically mentioned in the Fair Housing Act.

Home Mortgage Disclosure Act. The Home Mortgage Disclosure Act arose out of public concern over credit shortages in certain urban neighborhoods. The Home Mortgage Disclosure Act requires financial institutions to collect data that enable regulatory agencies to determine whether the financial institutions are serving the housing credit needs of the neighborhoods and communities in which they are located. The Home Mortgage Disclosure Act also requires the collection and disclosure of data about applicant and borrower characteristics as a way to identify possible discriminatory lending patterns. The vast amount of information that financial institutions collect and disclose concerning applicants and borrowers receives attention not only from state and Federal banking supervisory authorities but also from community-oriented organizations and the general public.

Real Estate Settlement Procedures Act. The Real Estate Settlement Procedures Act requires that lenders provide borrowers with disclosures regarding the nature and cost of real estate settlements. The Real Estate Settlement Procedures Act also prohibits abusive practices that increase borrowers’ costs, such as kickbacks and fee-splitting without providing settlement services.

Privacy. Under the Gramm-Leach-Bliley Act, all financial institutions are required to establish policies and procedures to restrict the sharing of non-public customer data with non-affiliated parties and to protect customer data from unauthorized access. In addition, the Fair Credit Reporting Act of 1971 includes many provisions concerning national credit reporting standards and permits consumers to opt out of information-sharing for marketing purposes among affiliated companies.

State Banking Regulation As an Ohio-chartered bank, The Middlefield Banking Company is subject to regular examination by the Ohio Division of Financial Institutions. State banking regulation affects the internal organization of The Middlefield Banking Company as well as its savings, lending, investment, and other activities. State banking regulation may contain limitations on an institution’s activities that are in addition to limitations imposed under federal banking law. The Ohio Division of Financial Institutions may initiate supervisory measures or formal enforcement actions, and if the grounds provided by law exist it may take possession and control of an Ohio-chartered bank.

Monetary Policy The earnings of financial institutions are affected by the policies of regulatory authorities, including monetary policy of the Federal Reserve Board. An important function of the Federal Reserve System is regulation of aggregate national credit and money supply. The Federal Reserve Board accomplishes these goals with measures such as open market transactions in securities, establishment of the discount rate on bank borrowings, and changes in reserve requirements against bank deposits. These methods are used in varying combinations to influence overall growth and distribution of financial institutions’ loans, investments and deposits, and they also affect interest rates charged on loans or paid on deposits. Monetary policy is influenced by many factors, including inflation, unemployment, short-term and long-term changes in the international trade balance, and fiscal policies of the United States government. Federal Reserve Board monetary policy has had a significant effect on the operating results of financial institutions in the past, and it can be expected to influence operating results in the future.

Legal Proceedings. From time to time Middlefield and The Middlefield Banking Company are involved in various legal proceedings that are incidental to its business. In the opinion of management, no current legal proceedings are material to the financial condition of Middlefield or the subsidiary bank, either individually or in the aggregate.

Voting Securities and Principal Holders. The following table shows the beneficial ownership of Middlefield common stock on November 17, 2016 on the part of each director, each executive officer identified in the Summary Compensation Table, and all directors and executive officers as a group. For purposes of the table, a person is considered to own beneficially any shares over which he or she exercises sole or shared voting or investment power or of which he or she has the right to acquire beneficial ownership within 60 days. Unless noted otherwise, voting power and investment power are exercised solely by the person named or they are shared with members of his or her household. The percentage figures are based on 2,250,893 shares outstanding, plus the number of shares each individual has the right to acquire within 60 days. The percentage ownership of each person identified in the table would be less than 1.0% if 45% of the 960,273 shares of Liberty Bank common stock outstanding are converted into Middlefield common stock at the exchange rate of 1.1934 shares of Middlefield common stock for each share of Liberty Bank common stock, resulting in issuance of 515,695 shares of Middlefield common stock. Middlefield is not aware of any person being owner of more than five percent of Middlefield common stock. To the best of Middlefield’s knowledge no Liberty stockholder to whom Middlefield common stock will be issued in the merger will own more than five percent of Middlefield common stock as a result of issuance of shares in the merger.

Director Stock Ownership Guidelines. Middlefield’s Corporate Governance Guidelines include stock ownership guidelines for directors. The guidelines state that within three years after election a director should own Middlefield common stock equal in value to at least two times the director’s yearly base compensation for service as a director of The Middlefield Banking Company, and three times base compensation within six years. As of December 31, 2015, the projected annual yearly compensation of a director other than the Chairman of the Board is $21,600.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF MIDDLEFIELD’S FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This information should be read in conjunction with the consolidated financial statements and accompanying notes to the financial statements. This Management’s Discussion and Analysis contains forward-looking statements. Forward-looking statements are based upon a variety of estimates and assumptions. The estimates and assumptions involve judgments about a number of things, including future economic, competitive, and financial market conditions and future business decisions. These matters are inherently subject to significant business, economic, and competitive uncertainties, all of which are difficult to predict and many of which are beyond Middlefield’s control. Although Middlefield believes its estimates and assumptions are reasonable, actual results could vary materially from those shown. Inclusion of forward-looking information does not constitute a representation by Middlefield or any other person that the indicated results will be achieved. Investors are cautioned not to place undue reliance on forward-looking information. These forward-looking statements may involve significant risks and uncertainties. Although Middlefield believes that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from the results in these forward-looking statements.

Capital maintenance is a priority. Middlefield’s Tier 1 leverage capital was 8.69% as of December 31, 2015, with total risk-based capital of 13.20%. The Middlefield Banking Company’s Tier 1 leverage capital was 9.23% as of December 31, 2015, with total risk-based capital of 13.73%. In 2015 The Middlefield Banking Company grew the balance sheet as a result of increasing loan volume. We also benefitted from strong income and stockholders’ equity experienced growth. The goal of the elevated capital levels is to account for potential economic stress in the markets in which Middlefield operates and to account for the levels of substandard and other nonperforming assets. At September 30, 2016, Middlefield’s Tier 1 leverage capital was 10.10%, with total risk-based capital of 14.69%, while The Middlefield Banking Company’s Tier 1 leverage capital was 9.02%, with total risk-based capital of 13.0%.

Longer-term prospects for growth. Continued reduction of nonperforming assets continues to be a higher priority than growth. Middlefield does not anticipate significant deposit growth. An increase in loan demand and the availability of high-quality lending opportunities continues to be the driver of growth potential and depends on a broad range of economic factors in the markets in which Middlefield operates, including the condition of real estate markets in northeastern Ohio and in central Ohio.

Nonperforming and classified assets held by the banking industry have decreased from previous elevated levels. Because of uncertainty about economic sustainability and the potential for other factors to have an adverse impact on the prospects for the banking industry, such as national and global economic and political factors, the bank regulatory agencies have insisted that banks increase the size of the buffer that protects a bank from unknown potential adverse events and circumstances: regulatory capital. The total number of banks and savings associations as of the end of 2015 is less than half the number at the end of 1990. Nevertheless, a large percentage of the institutions that remain are small, community-oriented institutions, although the share of total banking assets that they control continues to decline. As an increasing share of the banking universe is occupied by the largest institutions, and taking into account economic, demographic, and technological changes and a greatly expanding regulatory burden, the future of banking favors larger institutions. We believe these factors create a strong incentive for growth through industry consolidation, meaning acquisition of smaller institutions by larger institutions and mergers of smaller institutions as a defense to competitive pressure from larger institutions. We therefore believe that industry consolidation is likely to continue and that the pace of consolidation could actually accelerate.

The trend toward consolidation would be most advantageous for financial institution organizations that have a surplus of capital, a strategy for growth, a strong financial profile, and few if any regulatory supervisory concerns, the ingredients of prompt regulatory approval that could be a significant competitive advantage in the

market for financial institution mergers and acquisitions. Our goal is to acquire that advantage, although we give no assurance that our efforts to do so will succeed. We continue to commit significant resources to increase operational effectiveness in The Middlefield Banking Company. We continue to invest resources both to resolve existing nonperforming and substandard assets and to prevent growth in those asset classes.

Critical Accounting Policies.Allowance for loan and lease losses. Arriving at an appropriate level of allowance for loan and lease losses involves a high degree of judgment. Middlefield’s allowance for loan and lease losses provides for probable losses based upon evaluations of known and inherent risks in the loan portfolio. Management uses historical information to assess the adequacy of the allowance for loan and lease losses as well as the prevailing business environment, which is affected by changing economic conditions and various external factors and which may impact the portfolio in ways currently unforeseen. The allowance is increased by provisions for loan losses and by recoveries of loans previously charged-off and reduced by loans charged-off. For a full discussion of Middlefield’s methodology of assessing the adequacy of the reserve for loan losses, refer to Note 1 of “Notes to Consolidated Financial Statements” of this joint proxy statement/prospectus.

Valuation of Securities. Securities are classified as held to maturity or available for sale on the date of purchase. Only those securities classified as held to maturity are reported at amortized cost. Available-for-sale and trading securities are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income, net of related deferred income taxes, on the Consolidated Balance Sheet. The majority Middlefield’s securities are valued based on prices compiled by third party vendors using observable market data. However, certain securities are less actively traded and do not always have quoted market prices. The determination of their fair value, therefore, requires judgment, as this determination may require benchmarking to similar instruments or analyzing default and recovery rates. Examples include certain collateralized mortgage and debt obligations and high-yield debt securities. Realized securities gains or losses are reported within noninterest income in the Consolidated Statement of Income. The cost of securities sold is based on the specific identification method.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Investment securities are generally evaluated for OTTI under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 320, Investments – Debt and Equity Securities. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, whether the market decline was affected by macroeconomic conditions and whether Middlefield has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. In analyzing an issuer’s financial condition, Middlefield may consider whether the securities are issued by the federal government or its agencies, or U.S. government-sponsored enterprises, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.

When OTTI occurs, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If an entity intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income or loss. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Debt securities issued by U.S. government agencies, U.S. government-sponsored enterprises, and state and political subdivisions accounted for more than 97.9% of the total available-for-sale portfolio as of December 31, 2015, and more than 98.4% at September 30, 2016, and no credit losses are expected, given the explicit and implicit guarantees provided by the U.S. federal government and the lack of significant unrealized loss positions within the obligations of state and political subdivisions security portfolio. Middlefield considered the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:

Income Taxes. Middlefield estimates income tax expense based on amounts expected to be owed to the various tax jurisdictions in which Middlefield conducts business. On a quarterly basis, management assesses the reasonableness of Middlefield’s effective tax rate based upon management’s current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year. The estimated income tax expense is recorded in the Consolidated Statement of Income.

Deferred income tax assets and liabilities are determined using the balance sheet method and are reported in accrued taxes, interest and expenses in the Consolidated Balance Sheet. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities and recognizes enacted changes in tax rates and laws. Deferred tax assets are recognized to the extent they exist and are subject to a valuation allowance based on management’s judgment that realization is more likely than not.

Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in accrued taxes, interest and expenses in the Consolidated Balance Sheet. Middlefield evaluates and assesses the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintains tax accruals consistent with management’s evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance that impact the relative risks of tax positions. These changes, when they occur, can affect deferred taxes and accrued taxes as well as the current period’s income tax expense and can be significant to the operating results of Middlefield.

Goodwill and Other Intangible Assets. Goodwill is the excess of the purchase price over the fair value of the assets acquired in connection with business acquisitions accounted for as purchases. Other intangible assets consist of branch acquisition core deposit premiums. Initially, an assessment of qualitative factors (Step 0) is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is unnecessary. However, if we conclude otherwise, then we are required to perform the first step (Step 1) of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the

reporting unit. If the fair value is less than the carrying value, an expense may be required on our books to write down the goodwill to the proper carrying value. Step 2 of impairment testing, which is necessary only if Step 1 fails, compares the implied fair value of the goodwill with the carrying amount of the goodwill.

Middlefield must assess goodwill and other intangible assets each year for impairment. The gross carrying amount of goodwill and intangible assets is tested for impairment in the fourth quarter, after the annual forecasting process.

Fair Value of Financial Instruments. The disclosure of the fair value of financial instruments is based on available market prices or management’s estimates of the fair value of such instruments. Management consults with a third party for available market prices as well as performs calculations of the present value of contractual cash flows discounted at current comparative market inputs. Prepayment estimates are utilized when appropriate.

General. Middlefield’s total assets increased $57.6 million or 8.5% to $735.1 million at December 31, 2015 from $677.5 million at December 31, 2014. This was due to an increase in net loans of $63.6 million, which was partially offset by a decrease in investments of $7.8 million.

The increase in Middlefield’s total assets reflects a related increase in total liabilities of $59.2 million or 9.6% to a total balance of $672.8 million at December 31, 2015 from $613.7 million at December 31, 2014. Middlefield experienced a decrease in total stockholders’ equity of $1.6 million.

The increase in total liabilities was due to growth in deposits and short-term borrowings for the year. Total deposits increased $38.3 million or 6.5% to $624.4 million at December 31, 2015 from $586.1 million as of December 31, 2014. Short-term borrowings increased $21.0 million or 141.9% to $35.8 million at December 31, 2015 from $14.8 million as of December 31, 2014. The net decrease in total stockholders’ equity can be attributed to a $6.8 million increase in treasury stock, partially offset by an increase in retained earnings and common stock of $4.7 million and of $0.7 million, respectively.

Cash on hand and Federal funds sold. Cash and due from banks and federal funds sold represent cash and cash equivalents which decreased $1.9 million or 7.4% to $23.7 million at December 31, 2015 from $25.6 million at December 31, 2014. Deposits from customers into savings and checking accounts, loan and security repayments and proceeds from borrowed funds typically increase these accounts. Decreases result from customer withdrawals, new loan originations, security purchases and repayments of borrowed funds.

Securities. Management’s objective in structuring the portfolio is to maintain a prudent level of liquidity while providing an acceptable rate of return without sacrificing asset quality. Maturing securities have historically provided sufficient liquidity. The balance of total securities decreased $7.8 million, or 5.1%, as compared to 2014, with the ratio of securities to total assets decreasing to 19.9% at December 31, 2015, compared to 22.8% at December 31, 2014.

Middlefield benefits from owning mortgage-backed securities, which totaled $26.6 million or 18.6% of Middlefield’s total investment portfolio at December 31, 2015. The primary difference of mortgage-backed securities is the amortization of principal as compared to other types of investment securities, which deliver proceeds upon maturity or call date. The weighted-average federal tax-equivalent (FTE) yield on all debt securities at year-end 2015 was 4.11%, as compared to 4.18% at year-end 2014. While Middlefield’s focus is to generate interest revenue primarily through loan growth, management will continue to invest excess funds in securities when opportunities arise.

Loans receivable. The loans receivable category consists primarily of single-family mortgage loans used to purchase or refinance personal residences located within Middlefield’s market area and commercial real estate

loans used to finance properties that are used in the borrowers’ businesses or to finance investor-owned rental properties and commercial loans to finance the business operations and to a lesser extent construction and consumer loans. Net loans receivable increased $63.6 million or 13.7% to $527.3 million at December 31, 2015 from $463.7 million at December 31, 2014. Included in this growth were increases in real estate mortgages and C&I loans of $63.4 million and $7.6 million, respectively, but partially offset by an $8.2 million decrease in real estate construction loans.

The product mix in the loan portfolio is commercial and industrial loans equaling 8.0%, construction loans 4.1%, residential real estate loans 43.6%, commercial real estate loans 43.4% and consumer loans 0.9% at December 31, 2015 compared with 7.4%, 6.4%, 44.6%, 40.5% and 1.0%, respectively, at December 31, 2014.

Loans contributed 83.3% of total interest income in 2015 and 81.5% in 2014. The loan portfolio yield of 4.81% in 2015 was 30 basis points higher than the average yield for total interest-earning assets. Management recognizes that while the loan portfolio holds some of Middlefield’s highest yielding assets, it is inherently the most risky portfolio. Accordingly, management attempts to balance credit risk versus return with conservative credit standards. Management has developed and maintains comprehensive underwriting guidelines and a loan review function that monitors credits during and after the approval process. Management follows additional procedures to obtain current borrower financial information annually throughout the life of the loan obligation.

To minimize risks associated with changes in the borrower’s future repayment capacity, Middlefield generally requires scheduled periodic principal and interest payments on all types of loans and normally requires collateral.

Middlefield will continue to monitor the size of its loan portfolio growth. Middlefield’s lending markets have rebounded from the suppressed levels of loan originations in previous years. Middlefield anticipates total loan growth to be steady, with volume to continue at a moderate pace. Middlefield remains committed to sound underwriting practices without sacrificing asset quality and avoiding exposure to unnecessary risk that could weaken the credit quality of the portfolio.

FHLB stock. FHLB stock remained unchanged at $1.9 million at December 31, 2015 when compared to the prior year.

Goodwill. Goodwill results from prior business acquisitions and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Goodwill is assessed annually for impairment and any such impairment is recognized in the period identified by a charge to earnings.

Middlefield values core deposits and monitors the ongoing value of core deposit intangibles and goodwill on an annual basis. Goodwill balances were unchanged in 2015.

Bank owned life insurance. Bank owned life insurance (BOLI) is universal life insurance, purchased by Middlefield, on the lives of Middlefield’s officers. The beneficial aspects of these universal life insurance policies are tax-free earnings and a tax-free death benefit, which are realized by Middlefield as the owner of the policies. BOLI increased by $4.0 million to $13.1 million as of December 31, 2015 from $9.1 million at the end of 2014 as a result of the additional insurance purchases and increases in cash surrender value.

Deposits. Interest-earning assets are funded generally by both interest-bearing and noninterest-bearing core deposits. Deposits are influenced by changes in interest rates, economic conditions and competition from other banks. Middlefield considers various sources when evaluating funding needs, including but not limited to deposits, which represented 93.2% of Middlefield’s total funding sources at December 31, 2015. The deposit base consists of demand deposits, savings, money market accounts and time deposits. Total deposits increased $38.3 million or 6.5% to $624.4 million at December 31, 2015 from $586.1 million at December 31, 2014.

Savings and time deposits are the largest sources of funding for Middlefield’s earning assets, making up a combined 59.6% of total deposits. During 2015, time deposits increased $21.4 million, or 12.6% while savings increased $2.2 million, or 1.2%, from year-end 2014. The time deposit increase is primarily due to growth in out-of-market time deposits.

Demand deposit balances increased in 2015 by $11.8 million, or 7.3%, to finish at $173.7 million at year-end 2015 as compared to $161.9 million at year-end 2014. Middlefield will continue to experience increased competition for deposits in its market areas, which could challenge net growth in its deposit balances. Middlefield will continue to evaluate its deposit portfolio mix to properly employ both retail and wholesale funds to support earning assets and minimize interest costs.

Borrowed funds. Middlefield uses short and long-term borrowings as another source of funding to benefit asset growth and liquidity needs. These borrowings primarily include FHLB advances, junior subordinated debt, lines of credit from other banks and repurchase agreement borrowings. Borrowed funds increased $20.4 million or 79.9% to $45.8 million at December 31, 2015 from $25.4 million at December 31, 2014. Short-term borrowings increased $21.0 million in order to fund loan growth and purchase treasury shares.

Stockholders’ equity. Middlefield maintains a capital level that exceeds regulatory requirements as a margin of safety for its depositors and shareholders. All of the capital ratios exceeded the regulatory well-capitalized guidelines.

Stockholders’ equity totaled $62.3 million at December 31, 2015, compared to $63.9 million at December 31, 2014, which represents a decrease of 2.4%. Treasury stock increased $6.8 million, or 100.7%, from $6.7 million at December 31, 2014. Retained earnings increased $4.7 million resulting from net income, less cash dividends paid of $2.2 million, or $1.07 per share, year-to-date. Common stock increased $0.7 million or 1.9% to $36.2 million at December 31, 2015 from $35.5 million at December 31, 2014. Middlefield maintains a dividend reinvestment and stock purchase plan. The plan allows shareholders to purchase additional shares of Company stock. A benefit of the plan is to permit the shareholders to reinvest cash dividends as well as make supplemental purchases without the usual payment of brokerage commissions. During 2015, shareholders invested $0.7 million through the dividend reinvestment and stock purchase plan. These proceeds resulted in the issuance of 20,393 new shares at an average price of $32.17.

Average Balance Sheet and Yield/Rate Analysis. The following tables set forth, for the periods indicated, information concerning the total dollar amounts of interest income from interest-earning assets and the resultant average yields, the total dollar amounts of interest expense on interest-bearing liabilities and the resultant average costs, net interest income, interest rate spread and the net interest margin earned on average interest-earning assets. For purposes of these tables, average balances are calculated using monthly averages and the average loan balances include nonaccrual loans and exclude the allowance for loan and lease losses, and interest income includes accretion of net deferred loan fees. Yields on tax-exempt securities (tax-exempt for federal income tax purposes) are shown on a fully tax-equivalent basis utilizing a federal tax rate of 34%.

Analysis of Changes in Net Interest Income. The following tables analyze the changes in interest income and interest expense in terms of: (1) changes in volume of interest-earning assets and interest-bearing liabilities and (2) changes in yields and rates. The table reflects the extent to which changes in interest income and interest expense are attributable to changes in rate (change in rate multiplied by prior period volume), changes in volume (changes in volume multiplied by prior period rate) and changes attributable to the combined impact of volume/rate (change in rate multiplied by change in volume). The changes attributable to the combined impact of volume/rate are allocated on a consistent basis between the volume and rate variances. Changes in interest income on securities reflects the changes in interest income on a fully tax-equivalent basis.

Allowance for Loan and Lease Losses. The allowance for loan and lease losses (“ALLL”) represents the amount management estimates is adequate to provide for probable losses inherent in the loan portfolio as of the balance sheet date. Accordingly, all loan losses are charged to the allowance, and all recoveries credited to it. The ALLL is established through a provision for loan losses, which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the ALLL, taking into account the overall risk characteristics of the various portfolio segments, Middlefield’s loan loss experience, the impact of economic conditions on borrowers, and other relevant factors. The estimates used to determine the adequacy of the ALLL, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to significant change in the near term. The total ALLL is a combination of a specific allowance for identified problem loans and a general allowance for homogeneous loan pools.

The allowance for loan and lease loss balance as of December 31, 2015 totaled $6.4 million representing a $0.4 million decrease from the end of 2014. For the year of 2015, the provision for loan losses was $0.3 million which represented a decrease of $0.1 million from the $0.4 million provided during 2014. Asset quality is a high priority in our overall business plan as it relates to long-term asset growth projections. During 2015, net charge-offs increased by $0.2 million to $0.8 million compared to $0.6 million in 2014. Two key ratios to monitor asset quality performance are net charge-offs/average loans and the allowance for loan and lease losses/nonperforming loans. At year-end 2015, these ratios were 0.16% and 62.2%, respectively, compared to 0.13% and 75.7% in 2014.

The specific allowance incorporates the results of measuring impaired loans. The formula allowance is calculated by applying loss factors to outstanding loans by type, excluding loans for which a specific allowance has been determined. Loss factors are based on management’s determination of the amounts necessary for concentrations and changes in mix and volume of the loan portfolio, and consideration of historical loss experience.

The non-specific allowance is determined based upon management’s evaluation of existing economic and business conditions affecting the key lending areas of Middlefield and other conditions, such as new loan

products, credit quality trends, collateral values, unique industry conditions within portfolio segments that existed as of the balance sheet date, and the impact of those conditions on the collectability of the loan portfolio. Management reviews these conditions quarterly. The non-specific allowance is subject to a higher degree of uncertainty because it considers risk factors that may not be reflected in the historical loss factors.

Although management uses the best information available to make the determination of the adequacy of the ALLL at December 31, 2015, future adjustments could be necessary if circumstances or economic conditions differ substantially from the assumptions used in making the initial determinations. A downturn in the local economy could result in increased levels of nonperforming assets and charge-offs, increased loan loss provisions, and reductions in income. Additionally, as an integral part of the examination process, bank regulatory agencies periodically review a Bank’s ALLL. The banking agencies could require the recognition of additions to the loan loss allowance based on their judgment of information available to them at the time of their examination.

The following table sets forth information concerning Middlefield’s ALLL at the dates and for the periods presented.

The following table illustrates the allocation of Middlefield’s allowance for probable loan losses for each category of loan for each reported period. The allocation of the allowance to each category is not necessarily indicative of future loss in a particular category and does not restrict our use of the allowance to absorb losses in other loan categories.

Nonperforming assets.Nonperforming assets includes nonaccrual loans, troubled debt restructurings (TDRs), loans 90 days or more past due, assets purchased by EMORECO, OREO, and repossessed assets. A loan is classified as nonaccrual when, in the opinion of management, there are serious doubts about collectability of interest and principal. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of principal and interest is doubtful. Payments received on nonaccrual loans are applied against principal.

TDRs are those loans which Middlefield, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that Middlefield would not otherwise consider. Middlefield has 30 TDRs with a total balance of $3.1 million as of December 31, 2015 compared to 25 TDRs totaling $2.9 million as of December 31, 2014. Nonperforming loans amounted to $10.3 million or 1.9% of total loans and $9.0 million or 1.9% of total loans at December 31, 2015 and December 31, 2014, respectively. Of the nonperforming loans, 80.9% are secured by real estate as of December 31, 2015 as compared to 92.8% at December 31, 2014.

A major factor in determining the appropriateness of the ALLL is the type of collateral which secures the loans. Although this does not insure against all losses, the real estate provides substantial recovery, even in a distressed-sale and declining-value environment. The Middlefield Banking Company’s objective is to work with the borrower to minimize the burden of the debt service and to minimize the future loss exposure to Middlefield.

The following table summarizes nonperforming assets by category at December 31, 2013, 2014, and 2015.

Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Payments received on nonaccrual loans are recorded as income or applied against principal according to management’s judgment as to the collectability of principal.

A loan is considered impaired when it is probable the borrower will not repay the loan according to the original contractual terms of the loan agreement, including all troubled debt restructurings. Management has determined that first mortgage loans on one-to-four family properties and all consumer loans represent large groups of smaller-balance homogeneous loans that are to be collectively evaluated. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. A loan is not impaired during a period of delay in payment if Middlefield expects to collect all amounts due, including interest accrued at the contractual interest rate for the period of delay. Management evaluates all loans

identified as impaired individually. Middlefield estimates credit losses on impaired loans based on the present value of expected cash flows, or the fair value of the underlying collateral if loan repayment is expected to come from the sale or operation of the collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until that time, an allowance for loan and lease loss is maintained for estimated losses.

Interest income that would have been recorded had these loans not been placed on nonaccrual status was $259,000 in 2015; $207,000 in 2014; and $439,000 in 2013. Management is not aware of any trends or uncertainties related to any loans classified as doubtful or substandard that might have a material effect on earnings, liquidity, or capital resources.

General. Middlefield’s total assets ended the September 30, 2016 quarter at $762.3 million, an increase of $27.1 million or 3.7% from December 31, 2015. For the same time period, cash and cash equivalents decreased $474 thousand, or 2.0% while net loans increased $52.7 million, or 10.0%. Total liabilities increased $11.2 million, or 1.7% while stockholders’ equity increased $15.89 million, or 25.5%.

On June 30, 2016, Middlefield sold 360,815 shares of its common stock, without par value, at a purchase price of $33 per share, or an aggregate of $11,906,895.00, to certain institutional accredited investors pursuant to subscription agreements between Middlefield and such institutional investors in a private placement offering. Middlefield used the proceeds of the private placement to repay outstanding borrowings of approximately $9.5 million and for general corporate purposes.

Cash and cash equivalents. Cash and due from banks and Federal funds sold represent cash and cash equivalents. Cash and cash equivalents decreased $474 thousand at September 30, 2016 from $23.8 million at December 31, 2015. Deposits from customers into savings and checking accounts, loan and securities repayments and proceeds from borrowed funds typically increase these accounts. Decreases result from customer withdrawals, new loan originations, purchases of investment securities and repayments of borrowed funds.

Investment securities.Investment securities available for sale on September 30, 2016 totaled $123.1 million, a decrease of $23.4 million or 16% from $146.5 million at December 31, 2015. During this period Middlefield recorded repayments, calls, and maturities of $17.9 million. Sales of securities were $9.1 million with a net realized gain of $303,000. Securities purchases were $1.7 million during this period.

Loans receivable.The loans receivable category consists primarily of single-family mortgage loans used to purchase or refinance personal residences located within Middlefield’s market area and commercial real estate loans used to finance properties that are used in the borrowers’ businesses or to finance investor-owned rental properties, and to a lesser extent, construction and consumer loans. Net loans receivable increased $52.7 million or 10.0% to $580 million as of September 30, 2016 from $527.3 million at December 31, 2015 due to strategic growth goals. Included in this amount were increases in the residential real estate, commercial and industrial, and commercial real estate portfolios of $26.5 million, or 11.4%, $16.8 million, or 39.6%, and $13.9 million, or 6.0%, respectively. The construction portfolio decreased by $4.5 million, or 20.35%.

Middlefield’s Mortgage Banking operation generates loans for sale to FHLMC. Loans held for sale on September 30, 2016 totaled $0.9 million, a decrease of $0.2 million, or 20%, from December 31, 2015. This decrease is the result of fewer funded loans being held in the warehouse at quarter end.

Allowance for loan and lease losses and Asset Quality.Middlefield maintained the allowance for loan and lease losses at $6.3 million, or 1.1% of total loans, at September 30, 2016. For the three months ended September 30, 2016, net loan charge-offs totaled $137,000, or 0.09% of average loans, compared to net charge-offs of $131,000, or 0.10%, for the same period in 2015. To maintain the allowance for loan and lease losses,

Middlefield recorded a provision for loan loss of $105,000 in the three month period ending September 30, 2016. For the nine months ended September 30, 2016, net loan charge-offs totaled $366,000, or 0.09% of average loans, compared to net charge-offs of $736,000, or 0.20%, for the same period in 2015. To maintain the allowance for loan and lease losses, Middlefield recorded a provision for loan loss of $315,000 in the nine month period ending September 30, 2016.

Management analyzes the adequacy of the allowance for loan and lease losses regularly through reviews of the performance of the loan portfolio considering economic conditions, changes in interest rates and the effect of such changes on real estate values and changes in the amount and composition of the loan portfolio. The allowance for loan and lease losses is a significant estimate that is particularly susceptible to changes in the near term. Such evaluation includes a review of all loans designated as impaired, historical loan loss experience, the estimated fair value of the underlying collateral, economic conditions, current interest rates, trends in the borrower’s industry and other factors that management believes warrant recognition in providing for an appropriate allowance for loan and lease losses. Future additions or reductions to the allowance for loan and lease losses will be dependent on these factors. Additionally, Middlefield uses an outside party to conduct an independent review of commercial and commercial real estate loans that is designed to test management conclusions of risk ratings and the appropriateness of the allowance allocated to these loans. Middlefield uses the results of this review to help determine the effectiveness of policies and procedures and to assess the adequacy of the allowance for loan and lease losses allocated to these types of loans. Management believes the allowance for loan and lease losses is appropriately stated at June 30, 2016. Based on the variables involved and management’s judgments about uncertain outcomes, the determination of the allowance for loan and lease losses is considered a critical accounting policy.

Nonperforming assets.Middlefield has 27 TDRs with a total balance of $32.3 million as of September 30, 2016. Nonperforming loans secured by real estate totaled $8.8 million as of September 30, 2016, a decrease of $1.5 million from $10.3 million at December 31, 2015.

A major factor in determining the appropriateness of the allowance for loan and lease losses is the type of collateral which secures the loans. Of the total nonperforming loans at September 30, 2016, 87.97% were secured by real estate. Although this does not insure against all losses, the real estate typically provides for at least partial recovery, even in a distressed-sale and declining-value environment. Middlefield’s objective is to minimize future loss exposure.

Deposits.Middlefield considers various sources when evaluating funding needs, including but not limited to deposits, which are a significant source of funds totaling $639.3 million or 93.8% of Middlefield’s total funding sources at September 30, 2016. Total deposits increased $14.9 million or 2.4% at September 30, 2016 from $624.4 million at December 31, 2015. The increase in deposits is primarily related to increases in noninterest-

bearing demand and interest-bearing demand of $19.8 million or 17% and $9.8 million or 17.2%, respectively, at September 30, 2016. These increases were partially offset by decreases in time and savings accounts of $6.3 million, and $7.4 million, respectively.

Borrowed funds. Middlefield uses short and long-term borrowings as another source of funding used for asset growth and liquidity needs. These borrowings primarily include FHLB advances, junior subordinated debt, short-term borrowings from other banks, federal funds purchased, and repurchase agreements. Short-term borrowings decreased $3.0 million, or 8.4%, to $32.8 million as of September 30, 2016.

Stockholders’ equity.Stockholders’ equity increased $15.9 million, or 25.5%, to $78.2 million at September 30, 2016 from $62.3 million at December 31, 2015. This growth was largely the result of an increase in common stock of $11.6 million, or 32.1%. The increase in stockholders’ equity is primarily the result of the proceeds from the private placement discussed above. This growth was also the result of increases in retained earnings and accumulated other comprehensive income (“AOCI”) of $3.0 million and $1.2 million, respectively. The change to AOCI is due to available-for-sale securities fair value adjustments and the change in retained earnings is due to the year to date net income offset by dividends paid.

Middlefield posted net income of $6.9 million, compared to $7.2 million for the year ended December 31, 2014. On a per share basis, 2015 earnings were $3.39 per diluted share, representing a decrease from the $3.50 per diluted share for the year ended December 31, 2014. The return on average equity for the year ended December 31, 2015, was 10.62% and Middlefield’s return on average assets was 0.97%.

Net interest income.Net interest income, which is Middlefield’s largest revenue source, is the difference between interest income on earning assets and interest expense paid on liabilities. Net interest income is affected by the changes in interest rates and the composition of interest-earning assets and interest-bearing liabilities. Net interest income increased by $1.0 million in 2015 to $24.8 million compared to $23.8 million for 2014. This increase is the result of a $0.7 million increase in interest income and $0.3 million decrease in interest expense. Interest-earning assets averaged $670.8 million during 2015, a year-over-year increase of $24.1 million from $646.7 million for 2014. Middlefield’s average interest-bearing liabilities increased from $513.1 million in 2014 to $529.4 million in 2015.

The profit margin, or spread, on invested funds is a key performance indicator. Middlefield monitors two key performance indicators – net interest spread and net interest margin. The net interest spread represents the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. The net interest margin represents the overall profit margin: net interest income as a percentage of total interest-earning assets. This performance indicator gives effect to interest earned for all investable funds including the substantial volume of interest-free funds. For 2015 the net interest margin, measured on a fully taxable equivalent basis, increased to 3.94%, compared to 3.93% in 2014.

Interest income. Interest income increased $0.7 million to $28.6 million for 2015 which is attributable to a $1.1 million increase in interest and fees on loans. This change was the result of an increase in the average balance of loans receivable, partially offset by a lower yield on the portfolio. The average balance of loans receivable increased by $39.9 million or 8.8% to $494.9 million for the year ended December 31, 2015 as compared to $455.0 million for the year ended December 31, 2014. The loans receivable yield decreased to 4.81% for 2015, from 4.99% in 2014.

Interest on investment securities decreased $0.4 million to $4.6 million for 2015, compared to $5.0 million for 2014. The average balance of investment securities decreased $6.6 million to $152.0 million for the year ended December 31, 2015 as compared to $158.6 million for the year ended December 31, 2014. The investment securities yield slipped 7 basis points to 4.11% for 2015, compared to 4.18% for 2014.

Interest expense. Interest expense decreased $0.3 million or 6.1% to $3.8 million for 2015, compared with $4.1 million for 2014. This change in interest expense can be attributed to a 7 basis point decline in the rate paid on these liabilities, partially offset by an increase in the average balance of interest-bearing liabilities. For the year ended December 31, 2015 the average balance of interest-bearing liabilities increased by $16.3 million to $529.4 million as compared to $513.1 million for the year ended December 31, 2014. Interest incurred on deposits declined by $0.2 million for the year from $3.6 million in 2014 to $3.4 million for year-end 2015. The change in deposit expense was due to the declining average balance as well as a 6 basis point decline during the year. Interest expense incurred on FHLB advances, repurchase agreements, junior subordinated debt and other borrowings declined 9.8% from 2014. The decline was due to a 45 basis point decrease in the rate paid on these borrowings during the year.

Loan Loss Provision. The provision for loan losses is an operating expense recorded to maintain the related balance sheet allowance for loan and lease losses at an amount considered adequate to cover probable losses incurred in the normal course of lending. The provision for loan losses for the year ended December 31, 2015 was $0.3 million compared to $0.4 million in 2014. The loan loss provision is based upon management’s assessment of a variety of factors, including types and amounts of nonperforming loans, historical loss experience, collectability of collateral values and guaranties, pending legal action for collection of loans and related guaranties, and current economic conditions. The loan loss provision reflects management’s judgment of the current period cost-of-credit risk inherent in the loan portfolio. Although management believes the loan loss provision has been sufficient to maintain an adequate allowance for loan and lease losses, actual loan losses could exceed the amounts that have been charged to operations. The ratio of the allowance for loan and lease losses to total loans decreased to 1.20% of total loans at December 31, 2015 compared to the 1.45% at December 31, 2014.

During the fourth quarter of 2009, Middlefield created a new entity, EMORECO, Inc., which is designed to aid in troubled asset resolution. Since its inception, EMORECO has purchased $5.8 million of nonperforming assets.

Noninterest income. Noninterest income increased $0.4 million or 12.7% to $4.0 million for 2015 compared to $3.6 million for 2014. The increase is due to increase an increase in earnings on bank-owned life insurance.

Noninterest expense. Operating expenses increased $2.2 million, or 12.5% to $20.1 million for 2015 compared to $17.9 million for 2014. Salaries and benefits, other expense, and advertising expense increased $0.9 million, $0.6 million, and $0.2 million, or 10.6%, 22.1%, and 47.7%, respectively. The salaries increased as a result of the addition of key people and pay increases. The primary driver of increase in other expense was an increase in miscellaneous loan expense. Advertising expense increased as a result of strategic branding efforts. These were partially offset by a decrease in loss on other real estate owned of $0.2 million.

Provision for Income Taxes. The provision for income taxes decreased by $0.4 million, or 21.6%, to $1.6 million for 2015 from $2.0 million for 2014. Middlefield’s effective federal income tax rate in 2015 was 18.5% compared to 21.7% in 2014.

Middlefield posted net income of $7.2 million, compared to $7.0 million for the year ended December 31, 2013. On a per share basis, 2014 earnings were $3.50 per diluted share, representing an increase from the $3.47 per diluted share for the year ended December 31, 2013. The return on average equity for the year ended December 31, 2014, was 12.17% and Middlefield’s return on average assets was 1.07%.

Net interest income. Net interest income, which is Middlefield’s largest revenue source, is the difference between interest income on earning assets and interest expense paid on liabilities. Net interest income is affected

by the changes in interest rates and the composition of interest-earning assets and interest-bearing liabilities. Net interest income increased by $0.9 million in 2014 to $23.8 million compared to $22.9 million for 2013. This increase is the net result of a $1.2 million decrease in interest expense which was partially offset by a decrease in interest income of $0.3 million. Interest-earning assets averaged $644.9 million during 2014, a year-over-year increase of $8.2 million from $636.7 million for 2013. Middlefield’s average interest-bearing liabilities decreased from $543.6 million in 2013 to $513.1 million in 2014.

The profit margin, or spread, on invested funds is a key performance indicator. Middlefield monitors two key performance indicators – net interest spread and net interest margin. The net interest spread represents the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. The net interest margin represents the overall profit margin: net interest income as a percentage of total interest-earning assets. This performance indicator gives effect to interest earned for all investable funds including the substantial volume of interest-free funds. For 2014 the net interest margin, measured on a fully taxable equivalent basis, increased to 3.93%, compared to 3.85% in 2013.

Interest income. Interest income decreased $0.3 million to $27.9 million for 2014 which is attributable to a $0.6 million decrease in taxable interest on investment securities. The change in interest income on securities was the result of a decrease in the average balance of investment securities, partially offset by a higher yield on the portfolio. The average balance of investment securities decreased by $24.4 million or 13.3% to $158.6 million for the year ended December 31, 2014 as compared to $182.9 million for the year ended December 31, 2013. The investment security yield increased to 4.18% for 2014, from 3.90% in 2013.

Interest and fees on loans increased $0.2 million to $22.7 million for 2014, compared to $22.5 million for 2013. The average balance of loans increased $39.4 million to $455.0 million for the year ended December 31, 2014 as compared to $415.6 million for the year ended December 31, 2013 which was offset by a decline in the loan yield to 4.99% for 2014, compared to 5.41% for 2013.

Interest expense. Interest expense decreased $1.2 million or 22.5% to $4.1 million for 2014, compared with $5.3 million for 2013. This change in interest expense can be attributed to an 18 basis point decline in the rate paid on these liabilities, as well as a decrease in the average balance of interest-bearing liabilities. For the year ended December 31, 2014 the average balance of interest-bearing liabilities decreased by $30.5 million to $513.1 million as compared to $543.6 million for the year ended December 31, 2013. Interest incurred on deposits declined by $1.1 million for the year from $4.7 million in 2013 to $3.6 million for year-end 2014. The change in deposit expense was due to the declining average balance as well as a 16 basis point decline during the year. Interest expense incurred on FHLB advances, repurchase agreements, junior subordinated debt and other borrowings declined $0.1 million or 19.2% to $0.4 million for 2014, compared to $0.5 million for 2013. The decline was compounded by a 42 basis point decrease in the rate paid on these borrowings during the year.

Loan Loss Provision. The provision for loan losses is an operating expense recorded to maintain the related balance sheet allowance for loan and lease losses at an amount considered adequate to cover probable losses incurred in the normal course of lending. The provision for loan losses for the year ended December 31, 2014 was $0.4 million compared to $0.2 million in 2013. The loan loss provision is based upon management’s assessment of a variety of factors, including types and amounts of nonperforming loans, historical loss experience, collectability of collateral values and guaranties, pending legal action for collection of loans and related guaranties, and current economic conditions. The loan loss provision reflects management’s judgment of the current period cost-of-credit risk inherent in the loan portfolio. Although management believes the loan loss provision has been sufficient to maintain an adequate allowance for loan and lease losses, actual loan losses could exceed the amounts that have been charged to operations. The ratio of the allowance for loan and lease losses to total loans decreased to 1.45% of total loans at December 31, 2014 compared to the 1.62% at December 31, 2013.

Noninterest income. Noninterest income increased $0.4 million or 14.13% to $3.6 million for 2014 compared to $3.1 million for 2013. The increase is largely due to increases in investment security gains and gains on sale of loans of $0.2 million each. This amount was partially offset by a decrease to service charges on deposit accounts of $0.1 million.

Noninterest expense. Operating expenses increased $1.0 million, or 5.8% to $17.9 million for 2014 compared to $16.9 million for 2013. Salaries and benefits, other expense, and losses on other real estate owned increased $0.9 million, $0.4 million, and $0.2 million, or 11.4%, 15.8%, and 916.7%, respectively. These were partially offset by a decrease in Ohio state franchise tax of $0.3 million, or 44.7%.

Provision for Income Taxes. The provision for income taxes was essentially unchanged at $2.0 million for 2014. Middlefield’s effective federal income tax rate in 2014 was 21.7% compared to 22.0% in 2013.

Net income for the three months ended September 30, 2016, was $1.3 million, a $639,000, or 32.2% decrease from the amount earned during the same period in 2015. Diluted earnings per share for the quarter decreased to $0.60, compared to $0.96 from the same period in 2015. Net income for the nine months ended September 30, 2016, was $4.8 million, a $359,000, or 7.0% decrease from the amount earned during the same period in 2015. Diluted earnings per share decreased to $2.30, compared to $2.47 from the same period in 2015.

Middlefield’s annualized return on average assets (ROA) and return on average equity (ROE) for the quarter were .69% and 6.84%, respectively, compared with 1.10% and 12.67% for the same period in 2015. Middlefield’s ROA and ROE for the nine month period were 0.85% and 9.07%, respectively, compared with 0.97% and 10.83% for the same period in 2015.

Net interest income. Net interest income, the primary source of revenue, is determined by the interest rate spread, which is defined as the difference between income on earning assets and the cost of funds supporting those assets, and the relative amounts of interest-earning assets and interest-bearing liabilities. Management periodically adjusts the mix of assets and liabilities, as well as the rates earned or paid on those assets and liabilities in order to manage and improve net interest income. The level of interest rates and changes in the amount and composition of interest-earning assets and liabilities affect net interest income. Historically from an interest rate risk perspective, it has been management’s goal to maintain a balance between steady net interest income growth and the risks associated with interest rate fluctuations.

Net interest income for the three months ended September 30, 2016 totaled $6.4 million, an increase of 3.3% from that reported in the comparable period of 2015. The net interest margin was 3.68% for the third quarter of 2016, down from the 3.80% reported for the same quarter of 2015. The decrease is attributable to a $39.7 million increase in average assets earning interest at a lower rate than the same period in 2015. Net interest income for the nine months ended September 30, 2016 totaled $19.1 million, an increase of 3.5% from that reported in the comparable period of 2015. The net interest margin was 3.78%, down from the 3.88% reported for the same period of 2015. The decrease is attributable to a $37.9 million increase in average assets earning interest at a lower rate than the same period in 2015.

Interest income. Interest income increased $269,000, or 3.8%, for the three months ended September 30, 2016, compared to the same period in the prior year. This is attributable to an increase in interest and fees on loans of $488,000, partially offset by a decrease in interest earned on investment securities of $228,000. Interest income increased $921,000, or 4.3%, for the nine months ended September 30, 2016, compared to the same period in the prior year. This is attributable to an increase in interest and fees on loans of $1.3 million, partially offset by a decrease in interest earned on investment securities of $396,000. Interest earned on loans receivable increased $488,000, or 8.2%, for the three months ended September 30, 2016, compared to the same period in the prior year. This is attributable to an increase in average loan balances of $77.0 million, partially offset by a 28

basis point decrease in the average yield, to 4.42%. Interest earned on loans receivable increased $1.3 million or 7.3%, for the nine months ended September 30, 2016, compared to the same period in the prior year. This is attributable to an increase in average loan balances of $70.3 million, partially offset by a 30 basis point decrease in the average yield, to 4.55%.

Interest earned on securities decreased by $228,000 for the three months ended September 30, 2016 when compared to the same period in the prior year. The average balance decreased $28.3 million, or 18.47% while the 4.06% yield on the investment portfolio increased by 1 basis point, from 4.05%, for the same period in the prior year. Interest earned on securities decreased by $396,000 for the nine months ended September 30, 2016 when compared to the same period in the prior year. The average balance decreased $17.7 million, or 11.53% while the 4.17% yield on the investment portfolio increased by 7 basis points, from 4.10%, for the same period in the prior year.

Interest expense. Interest expense increased $67,000, or 7%, for the three months ended September 30, 2016, compared to the same period in the prior year. The increase is largely attributable to an increase of $29.0 million, or 178%, in the average balance of borrowings, partially offset by a decrease in cost of 110 basis points. Interest expense increased $285,000, or 10.1%, for the nine months ended September 30, 2016, compared to the same period in the prior year. The increase is largely attributable to an increase of $26.8 million, or 148.4%, in the average balance of borrowings, partially offset by a decrease in cost of 51 basis points.

Provision for loan losses. The provision for loan losses represents the charge to income necessary to adjust the allowance for loan and lease losses to an amount that represents management’s assessment of the estimated probable incurred credit losses inherent in the loan portfolio. Each quarter management performs a review of estimated probable incurred credit losses in the loan portfolio. Based on this review, a provision for loan losses of $105,000 was recorded for the quarter ended September 30, 2016 as well as the quarter ending September 30, 2015. A provision for loan losses of $315,000 was recorded for the nine month period ended September 30, 2016, compared to $210,000 in the same period in 2015. Nonperforming loans were $8.8 million, or 1.5% of total loans at September 30, 2016 compared with $8.9 million, or 1.75% at September 30, 2015. For the three months ended September 30, 2016, net loan charge-offs totaled $137,000, or 0.09% of average loans, compared to net charge-offs of $131,000, or 0.10%, for the third quarter of 2015. For the nine months ended September 30, 2016, net loan charge-offs totaled $366,000, or 0.09% of average loans, compared to net charge-offs of $736,000, or 0.20%, for the same period in 2015.

Noninterest income. Noninterest income increased $131,000 for the three months ended September 30, 2016 over the comparable 2015 period. This increase was largely the result of an increase in net investment security gains of $211,000. Noninterest income increased $193,000 for the nine months ended September 30, 2016 over the comparable 2015 period. This increase was largely the result of an increase in net investment security gains of $46,000 and an increase of $61,000 in service charges on deposit accounts.

Noninterest expense. Noninterest expense of $5.6 million for the third quarter 2016 was 21.3%, or $993,000 more than the third quarter of 2015. Salaries and benefits, professional fees, and other expenses increased $392,000, or 17.2%, $318,000, or 138.9%, and $187,000, or 38.2%, respectively. These were partially offset by a gain on other real estate sales of $73,000. The salary increase is mostly due to an additional pay cycle in the third quarter of 2016. Other real estate expense decreased due to a return to normal from the heightened activity during the same period in 2015. Noninterest expense of $15.9 million for the nine month period ended September 30, 2016 was 8.3% or $1.22 million more than the same period in 2015. Salaries and employee benefits and professional fees increased $535,000 and $232,000, 7.4% or 28.1%, respectively. These were partially offset by a decrease in other real estate expense of $221,000, or 49.2%. The salary increase is mostly due to annual pay adjustments. Other real estate expense decreased due to a return to normal from the heightened activity during the same period in 2015. Professional fees are higher due to additional services provided related to the acquisition. Acquisition costs through third quarter 2016 were $314,000 mainly for legal, consulting and tax services.

Provision for income taxes. Middlefield recognized $261,000 in income tax expense, which reflected an effective tax rate of 16.3% for the three months ended September 30, 2016, as compared to $544,000 with an effective tax rate of 21.5% for the comparable 2015 period. Middlefield recognized $1.1 million in income tax expense, which reflected an effective tax rate of 19.2% for the nine months ended September 30, 2016, as compared to $1.3 million with an effective tax rate of 19.8% for the comparable 2015 period. The provision is directly correlated to the increase in net income before taxes.

Asset and Liability Management. The primary objective of Middlefield’s asset and liability management function is to maximize Middlefield’s net interest income while simultaneously maintaining an acceptable level of interest rate risk given Middlefield’s operating environment, capital and liquidity requirements, performance objectives and overall business focus. The principal determinant of the exposure of Middlefield’s earnings to interest rate risk is the timing difference between the re-pricing or maturity of interest-earning assets and the re-pricing or maturity of its interest-bearing liabilities. Middlefield’s asset and liability management policies are designed to decrease interest rate sensitivity primarily by shortening the maturities of interest-earning assets while at the same time extending the maturities of interest-bearing liabilities. The Board of Directors of Middlefield continues to believe in a strong asset/liability management process in order to insulate Middlefield from material and prolonged increases in interest rates. Mortgage-backed securities generally increase the quality of Middlefield’s assets by virtue of the insurance or guarantees that back them, are more liquid than individual mortgage loans and may be used to collateralize borrowings or other obligations of Middlefield.

Middlefield’s Board of Directors has established an Asset and Liability Management Committee consisting of outside directors and senior management. This committee, which meets quarterly, generally monitors various asset and liability management policies and strategies. Middlefield engages an external consultant to facilitate income simulation modeling on a quarterly basis. This modeling measures interest rate risk and sensitivity. The Asset and Liability Management Committee believes the various rate scenarios of the simulation modeling enable Middlefield to more accurately evaluate and manage the exposure of interest rate fluctuations on net interest income, the yield curve, various loan and mortgage-backed security prepayments, and deposit decay assumptions. Earnings simulation modeling and assumptions about the timing and volatility of cash flows are critical in net portfolio equity valuation analysis. Particularly important are the assumptions driving mortgage prepayments and expected attrition of the core deposit portfolios. These assumptions are based on Middlefield’s historical experience and industry standards and are applied consistently across all rate risk measures.

Middlefield established the following guidelines for assessing interest rate risk:

The following table presents the simulated impact of a 200 basis point upward or 100 basis point downward shift of market interest rates on net interest income, and the change in portfolio equity. This analysis was done assuming the interest-earning asset and interest-bearing liability levels at December 31, 2015 remained constant. The impact of the market rate movements was developed by simulating the effects of rates changing gradually from the December 31, 2015 levels for net interest income, and portfolio equity. The impact of market rate movements was developed by simulating the effects of an immediate and permanent change in rates at December 31, 2015 for portfolio equity.

The impact of market rate movements was developed by simulating the effects of an immediate and permanent change in rates at September 30, 2016 for portfolio equity:

Liquidity and Capital Resources. Management’s objective in managing liquidity is maintaining the ability to continue meeting the cash flow needs of banking customers, such as borrowings or deposit withdrawals, as well as Middlefield’s own financial commitments. The principal sources of liquidity are net income, loan payments, maturing and principal reductions on securities and sales of securities available for sale, federal funds sold and cash and deposits with banks. Along with its liquid assets, Middlefield has additional sources of liquidity available to ensure that adequate funds are available as needed. These include, but are not limited to, the purchase of federal funds, and the ability to borrow funds under line of credit agreements with correspondent banks and a borrowing agreement with the Federal Home Loan Bank of Cincinnati, Ohio and the adjustment of interest rates to obtain depositors. Management believes Middlefield has the capital adequacy, profitability and reputation to meet the current and projected needs of its customers.

Liquidity is managed based on factors including core deposits as a percentage of total deposits, the level of funding source diversification, the allocation and amount of deposits among deposit types, the short-term funding sources used to fund assets, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets readily converted to cash without undue loss, the amount of cash and liquid securities we hold, and the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities and other factors.

Middlefield’s liquid assets consist of cash and cash equivalents, which include investments in very short-term investments (i.e., federal funds sold), and investment securities classified as available for sale. The level of these assets is dependent on Middlefield’s operating, investing, and financing activities during any given period. At December 31, 2015, cash and cash equivalents totaled $23.8 million or 3.2% of total assets while investment securities classified as available for sale totaled $146.5 million or 19.9% of total assets. Management believes that the liquidity needs of Middlefield are satisfied by the current balance of cash and cash equivalents, readily available access to traditional funding sources, FHLB advances, junior subordinated debt, and the portion of the investment and loan portfolios that mature within one year. These sources of funds will enable Middlefield to meet cash obligations and off-balance sheet commitments as they come due.

Operating activities provided net cash of $7.2 million, $7.5 million, and $9.9 million for 2015, 2014, and 2013, respectively, generated principally from net income of $6.9 million, $7.2 million, and $7.0 million in each of these respective periods.

Investing activities used $59.4 million which consisted primarily of investment activity and loan originations. The cash usages primarily consisted of loan increases of $63.9 million and investment purchases of $21.9 million. Partially offsetting the usage are proceeds from repayments and maturities and proceeds from sale of securities of $13.5 million and $15.7 million, respectively. For the same period ended 2014, investing activities used $26.7 million which consisted primarily of investment activity and loan originations. The cash usages primarily consisted of investment purchases of $12.3 million and loan increases of $36.2 million. Partially offsetting the usage are proceeds from repayments and maturities and proceeds from sale of securities of $13.5 million and $8.4 million, respectively. For the same period ended 2013, investing activities used $6.1 million which consisted primarily of investment activity and loan originations. The cash usages primarily consisted of investment purchases of $25.8 million and loan increases of $29.8 million. Partially offsetting the usage are proceeds from repayments and maturities and proceeds from sale of securities of $25.4 million and $25.1 million, respectively.

Financing activities consist of the solicitation and repayment of customer deposits, borrowings and repayments, treasury stock activity, and the payment of dividends. During 2015, net cash provided by financing activities totaled $50.4 million, principally derived from increases in deposit accounts and short-term borrowings of $38.3 million and $21.0 million, respectively, and partially offset by treasury stock purchase of $6.8 million and $2.2 million in cash dividends. During 2014, net cash provided by financing activities totaled $18.7 million, principally derived from increases in deposit accounts and short-term borrowings of $17.3 million and $4.0 million, respectively, and partially offset by $2.1 million in cash dividends. During 2013, net cash used for financing activities totaled $23.0 million, principally derived from a decrease in deposit accounts of $24.5 million and partially offset by $4.3 million increase in short-term borrowings.

Liquidity may be adversely affected by many circumstances, including unexpected deposit outflows and increased draws on lines of credit. Management monitors projected liquidity needs and determines the desirable level based in part on Middlefield’s commitment to make loans and management’s assessment of Middlefield’s ability to generate funds. Middlefield anticipates having sufficient liquidity to satisfy estimated short and long-term funding needs.

For the nine months ended September 30, 2016, the adjustments to reconcile net income to net cash from operating activities consisted mainly of depreciation and amortization of premises and equipment, the provision for loan losses, net amortization of securities and net changes in other assets and liabilities. For a more detailed illustration of sources and uses of cash, refer to the Condensed Consolidated Statements of Cash Flows.

Capital Resources. Middlefield’s primary source of capital is retained earnings. Historically, Middlefield has generated net retained income to support normal growth and expansion. Management has developed a capital planning policy to not only ensure regulatory compliance but capital adequacy for future expansion.

Inflation. Substantially all of Middlefield’s assets and liabilities relate to banking activities and are monetary in nature. The consolidated financial statements and related financial data are presented in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). GAAP currently requires Middlefield to measure the financial position and results of operations in terms of historical dollars, with the exception of securities available for sale, impaired loans and other real estate loans that are measured at fair value. Changes in the value of money due to rising inflation can cause purchasing power loss.

Management’s opinion is that movements in interest rates affect the financial condition and results of operations to a greater degree than changes in the rate of inflation. It should be noted that interest rates and inflation do affect each other, but do not always move in correlation with each other. Middlefield’s ability to match the interest sensitivity of its financial assets to the interest sensitivity of its liabilities in its asset/liability management may tend to minimize the effect of changes in interest rates on performance.

Liberty operates under a national charter and provides full banking services. Liberty is subject to regulation by the OCC and the FDIC. Liberty has branches in Beachwood, Solon, and Twinsburg, Ohio; Liberty’s administrative office is located in Beachwood, Ohio.

Liberty has two operating subsidiaries. LBNA Financial LLC was formed in 2010 to reduce premiums paid on title insurance, and LBNA Insurance LLC was formed in 2014 to reduce premiums paid on Liberty’s corporate insurance coverage.

The following is a discussion and analysis of Liberty’s consolidated financial condition at ~~June~~September 30, 2016, December 31, 2015 and December 31, 2014 and results of operations for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 and the years ended December 31, 2015, and 2014 and should be read in conjunction with Liberty’s consolidated financial statements and notes thereto presented in this proxy statement/prospectus beginning on page F-1.

Liberty’s consolidated financial statements are prepared in conformity with GAAP and follow general practices within the industry in which Liberty operates. This preparation requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions, and judgments reflected in the financial statements. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and, therefore, have a greater possibility of producing results that could be materially different from originally reported. Liberty’s management believes the following policies are both important to the portrayal of its financial condition and results of operations and require subjective or complex judgments; therefore, management considers the following to be critical accounting policies.

The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes that the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance methodology is consistent for each portfolio segment.

The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. Management estimates the allowance balance required based on past loan loss experience, information about specific borrower and loan situations, estimated collateral values, economic and other factors. Loans considered impaired are individually analyzed for impairment and required reserves are estimated for each impaired loan. A loan is considered impaired when full payment under the loan terms is not expected. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impaired amounts are generally calculated using the fair value of the collateral for

the loan. Troubled debt restructurings are considered to be collateral dependent; the loans are reported at the fair value of the collateral. For troubled debt restructurings that subsequently default, Liberty determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses.

The general component of the reserve covers non-impaired loans and is based on historical loss experience adjusted for current factors. Nonimpaired loans are grouped into pools by loan risk ratings and each pool is further segmented by primary collateral type. Loss rates are determined based on historical loss rates and applied to each loan pool using a loss migration analysis. The loss migration analysis tracks the loss experience for pools of loans over a period of time. Historical loss rates consider the most recent 60 months. The estimated reserve required based on historical loss rates are then considered for adjustment based on current qualitative and economic factors that management believes may cause future loss experiences to differ from actual historical loan loss experience. The key qualitative and economic factors considered include nature and volume of the loan portfolio, volume and severity of past due and classified loans, concentration of credit, lending policies and procedures, national and local economic and business conditions, experience of lending staff and management, quality of the loan review system, value of underlying collateral for collateral dependent loans, and other external factors. Although allocations of the allowance may be made for specific loans and loan portfolio segments, the entire allowance is available for any loan or loan portfolio segment that in management’s judgment should be charged off. Management believes it has established an allowance for probable loan losses as appropriate under GAAP.

Liberty classifies its debt securities as held to maturity when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available for sale when they might be sold before maturity. Securities classified as held to maturity are recorded at cost or amortized cost. Available for sale securities are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss). Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are calculated based on market prices of similar securities. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these securities could differ from the estimated amounts, thereby affecting Liberty’s financial position, results of operations and cash flows. If the estimated value of a security is less than the cost or amortized cost, Liberty evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of the security. If such an event or change has occurred and Liberty determines that the impairment is other-than-temporary, Liberty expenses the impairment of the security in the period in which the event or change occurred.

Interest income includes amortization of purchase premium or accretion of discount. Premiums and discounts are recognized in interest income using the level-yield method without anticipating prepayments except for mortgage-backed and collateralized mortgage obligation securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting basis and the tax basis of Liberty’s assets and liabilities and expected benefits of operating loss carryforwards and credit carryforwards. Deferred taxes are recognized for the estimated taxes ultimately payable or recoverable based on enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Changes in enacted tax rates and laws are reflected in the financial statements in the periods in which they occur.

Liberty recognizes a tax position as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, including resolution of the related appeals or litigation processes. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Liberty recognizes interest and penalties related to income tax matters in income tax expense.

Fair values of impaired loans, other real estate owned, and other financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note in Liberty’s audited consolidated financial statements. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

The profitability of Liberty’s operations depends primarily on its net interest income after provision for loan losses, which is the difference between interest earned on interest earning assets and interest paid on interest bearing liabilities less provision for loan losses. The provision for loan losses is dependent on changes in Liberty’s loan portfolio and management’s assessment of the collectability of Liberty’s loan portfolio as well as prevailing economic and market conditions. Liberty’s net income is also affected by noninterest income, non-interest expense and income tax expense

Liberty had net income of approximately ~~$1.1~~$1.7 million for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to net income of ~~$768 thousand~~approximately $1.2 million for the ~~six~~nine months ended ~~June~~September 30, 2015. Fully diluted earnings per common share were ~~$1.14~~$1.71 for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to ~~$0.80~~$1.27 for the ~~six~~nine months ended ~~June~~September 30, 2015.

The ~~$332~~$440 thousand increase in earnings from the ~~six~~nine months ended ~~June~~September 30, 2015 to the ~~six~~nine months ended ~~June~~September 30, 2016 was primarily due to an increase of ~~$822 thousand~~$1.1 million in net interest income offset by a ~~$376~~$715 thousand increase in ~~non-interest~~noninterest expense.

Liberty had net income of approximately $1.8 million for the year ended December 31, 2015 compared to net income of $3.0 million for the year ended December 31, 2014. Fully diluted earnings per common share were $0.19 for the year ended December 31, 2015 compared to $0.33 for 2014.

The $1.2 million decrease in earnings from the year ended December 31, 2014 to the year ended December 31, 2015 was primarily due to a negative provision for loan losses in the amount of $917 thousand, a decrease in net interest income and a decrease in the amount of gains recognized on the sale of education loans and SBA loans.

The following tables present, for the periods indicated, the total dollar amount of interest income from average interest earning assets and the related yields, as well as the interest expense on average interest bearing

liabilities, and the related costs, expressed both in dollars and rates (dollars in thousands), and net interest income. Liberty does not hold any loans or investments that have a tax-favored status.

Net interest income increased ~~$822 thousand~~$1.1 million during the ~~six~~nine months ended ~~June~~September 30, 2016 compared to the ~~six~~nine months ended ~~June~~September 30, 2015. The increase in net interest income was primarily due to an increase in loan volume and loan rate, ~~an increase~~a decrease in income from investments and a decrease in interest expense. The net interest margin, expressed on a fully ~~tax equivalent~~tax-equivalent basis, was ~~3.99%~~4.01% for the ~~six~~nine months ended ~~June~~September 30, 2016 and ~~3.57%~~3.59% for the ~~six~~nine months ended ~~June~~September 30, 2015. The increase in the margin was primarily due to increased yields on loans.

The following table sets forth average balances, average yields and costs, and certain other information at and for the fiscal years indicated. No tax-equivalent yield adjustments were made, as the effect thereof was not material. Average balances are derived from daily average balances. ~~Non-accrual~~Nonaccrual loans were included in the computation of average balances, but have been reflected in the table as loans carrying a zero yield. The yields set forth below include the effect of deferred fees, discounts and premiums that are amortized or accreted to interest income or interest expense.

Net interest income decreased $390 thousand during the year ended December 31, 2015 compared to the year ended December 31, 2014. The decrease in net interest income was due to significantly lower loan yields. The net interest margin, expressed on a fully ~~tax equivalent~~tax-equivalent basis, was 3.59% for 2015 and 3.82% for 2014.

The following table presents the extent to which changes in volume and interest rates of interest earning assets and interest bearing liabilities have affected interest income and interest expense during the periods indicated. Information is provided in each category with respect to (i) changes attributable to changes in volume (changes in volume multiplied by prior period rate), (ii) changes attributable to changes in rates (changes in rates multiplied by prior period volume) and (iii) change attributable to a combination of changes in rate and volume (change in rates multiplied by the changes in volume). Changes attributable to the combined impact of volume and rate have been allocated proportionately to the changes due to volume and the changes due to rate.

~~Non-interest~~Noninterest income increased by ~~$48~~$226 thousand, or ~~8.4%~~26.4%, for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to the ~~six~~nine months ended ~~June~~September 30, 2015.

~~Non-interest~~Noninterest expenses increased ~~$376~~$715 thousand or ~~12%~~15.6% for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to the same period in 2015. The increase was primarily due to additional loan officers, ~~and~~ an increase in the reserve for incentive and retention ~~bonuses.~~bonuses, and increased legal costs from the Merger. Advertising expense for the ~~six~~nine months ended ~~June~~September 30, 2016 increased ~~133%~~81.8% from the same period in 2015.

Noninterest expenses decreased $156 thousand for the twelve months ended December 31, 2015 compared to the twelve months ended December 31, 2014. The decrease was due to continued expense reductions but

primarily due to reduced consulting and legal costs. Advertising expense for the twelve months ended December 31, 2015 increased $98 thousand or 428% compared to 2014.

Income tax expense for the ~~six~~nine months ended ~~June~~September 30, 2016 was ~~$567~~$856 thousand compared to ~~$404~~$643 thousand for the ~~six~~nine months ended ~~June~~September 30, 2015. The effective tax rate was 34% for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to 34.5% for the ~~six~~nine months ended ~~June~~September 30, 2015. The increase in income tax expense was primarily due to an increase in pre-tax income in the ~~six~~nine months ended ~~June~~September 30, 2016.

Income tax expense for the year ended December 31, 2015 was $943 thousand compared to $1.1 million for the year ended December 31, 2014. The decrease in income tax expense was primarily due to a decrease in the pre-tax income in 2015. The effective tax rate was 34.5% for the year ended December 31, 2015 compared to 27% for the year ended December 31, 2014. The decrease in the effective tax rate was primarily due to a tax adjustment from 2013.

Total assets increased ~~$10.1~~$9.1 million, or ~~4.7%~~4.3%, from December 31, 2015 to ~~June~~September 30, 2016 primarily due to loan growth. Net loans increased from December 31, 2015 to ~~June~~September 30, 2016 by ~~$8.0~~$18.1 million, or ~~4.5%~~10.3%, primarily due to growth of commercial loans, commercial real estate loans, and education loans.

Total liabilities increased by ~~$9.3~~$8.0 million, or ~~5.1%~~4.4%, from December 31, 2015 to ~~June~~September 30, 2016 primarily due to an increase in deposits, which were the primary source of funding for Liberty’s asset growth. Total deposits increased by ~~$8.7~~$7.0 million, or ~~4.8%~~3.9%, to ~~$189.9~~$188.2 million at ~~June~~September 30, 2016 from $181.2 million at December 31, 2015, primarily due to growth in ~~both non-interest and~~ interest bearing deposits. Liberty had no borrowings at ~~June~~September 30, 2016 or December 31, 2015.

Total stockholders’ equity increased ~~$770 thousand~~$1.2 million at ~~June~~September 30, 2016 compared to December 31, 2015 primarily as a result of earnings recorded during the period.

Total assets increased $1.7 million from December 31, 2014 to December 31, 2015 primarily due to an increase in loans offset by a decrease in cash and due from banks. Net loans increased from 2014 to 2015 by $9.9 million, or 5.9%, primarily due to growth of commercial loans and commercial real estate loans. Cash and due from banks decreased $6.4 million as excess liquidity was used to fund the loan growth.

Total liabilities stayed relatively unchanged from the $182.1 million at December 31, 2015 compared to $181.9 million at December 31, 2014. Total deposits increased by $1.5 million to $181.2 million at December 31, 2015 from $179.7 million at December 31, 2014, primarily due to growth in both non-interest and interest bearing deposits. Liberty had no borrowings at December 31, 2015 or December 31, 2014.

Total stockholders’ equity increased $1.5 million at December 31, 2015 compared to December 31, 2014 primarily as a result of earnings recorded during 2015.

The following table sets forth the amortized cost and fair value of Liberty’s securities, by type of security, as of the dates indicated.

The following table sets forth certain information regarding contractual maturities of Liberty’s securities, by type of security, as of the dates indicated.

Securities are classified as trading, held to maturity, or available for sale upon their acquisition. Securities classified as trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value with unrealized gains and losses recorded in current earnings. Securities held to maturity are securities that Liberty has the positive intent and the ability to hold to maturity; these securities are reported at amortized cost and adjusted for unamortized premiums and discounts. All other securities are classified as available for sale. Securities classified as available for sale are reported at fair value with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. All investments have been classified as available for sale.

~~Due to volatility in market interest rates,~~ Liberty has not purchased securities since 2011.

On a monthly basis, Liberty’s board of directors monitors all loan portfolio activity including levels of concentrations. Liberty’s asset quality management includes strong underwriting characteristics, conservative interest rates to known customers and a comprehensive risk rating component. The Liberty directors who serve on the board loan committee participate in the credit approval process. Liberty’s loan officers have no individual loan authority. Liberty’s lending philosophy is to invest in relationships in its local markets in order to provide for sound, profitable growth and support the credit needs of these markets.

~~Non-performing~~Nonperforming loans include loans accounted for on a ~~non-accrual~~nonaccrual basis and accruing loans contractually past due 90 days or more as to interest or principal. Management reviews the loan portfolio for problem loans on an ongoing basis. During the ordinary course of business, management becomes aware of borrowers that may not be able to meet the contractual requirements of loan agreements. These loans are placed under close supervision with consideration given to placing the loan on ~~non-accrual~~nonaccrual status, increasing the allowance for loan losses and (if appropriate) partial or full charge-off. After a loan is placed on ~~non-accrual~~nonaccrual status, any interest previously accrued but not yet collected is reversed against current income. Generally, interest received on ~~non-accrual~~nonaccrual loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans will not be placed back on accrual status unless back interest and principal payments are made. Liberty’s general policy is to place consumer loans 90 days past due on ~~non-accrual~~nonaccrual status, as well as those loans that continue to pay, but display a well-defined material weakness.

~~Non-performing~~Nonperforming assets consists of ~~non-performing~~nonperforming loans as well as other repossessed assets and other real estate owned. Other real estate owned represents properties acquired through foreclosure or other proceedings and is recorded at fair value less the estimated cost of disposal at the date of acquisition. Other real estate owned is evaluated regularly to ensure that the recorded amount is supported by its current fair value. Valuation allowances to reduce the carrying amount to fair value less estimated costs of disposal are recorded as necessary. At ~~June~~September 30, 2016, December 31, 2015 and December 31, 2014, Liberty held other real estate which was being carried at $-0-, $-0-, and $211,500, respectively. Sale of real estate owned resulted in a gain of $97,360 in 2015. No real estate owned was sold during the ~~six~~nine months ended ~~June~~September 30, 2016 or in 2014.

Classified Assets. Federal regulations provide for the classification of loans and other assets, such as debt and equity securities considered by the OCC to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific allowance for loan losses is not warranted. Assets that do not currently expose the insured institution to

sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” by management. At ~~June~~September 30, 2016, Liberty had ~~$399,719~~$354,720 of loans designated by management as “special mention,” and $2.9 million of loans designated as “substandard.”

When an insured institution classifies problem assets as either substandard or doubtful, it may establish general allowances in an amount deemed prudent by management to cover losses that are both probable and reasonable to estimate. General allowances represent allowances which have been established to cover accrued losses associated with lending activities that were both probable and reasonable to estimate, but which, unlike specific allowances, have not been allocated to particular problem assets. When an insured institution classifies problem assets as “loss,” it is required either to establish a specific allowance for losses equal to 100% of that portion of the asset so classified or to charge-off such amount. An institution’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by the regulatory authorities, which may require the establishment of additional general or specific allowances.

In connection with the filing of periodic regulatory reports and in accordance with Liberty’s classification of assets policy, Liberty regularly reviews the problem loans in its portfolio to determine whether any loans require classification in accordance with applicable regulations. Loans are listed on the “watch list” initially because of emerging financial weaknesses even though the loan is currently performing as agreed, or delinquency status, or if the loan possesses weaknesses although currently performing. If a loan deteriorates in asset quality, the classification is changed to “special mention,” “substandard,” “doubtful” or “loss” depending on the circumstances and the evaluation. Management reviews the status of each loan on the classified list on a monthly basis with the full board of directors.

The following table sets forth the amounts of classified loans and loans designated as special mention as of ~~June~~September 30, 2016, and December 31, 2015, 2014, 2013 and 2012.

Liberty’s exposure to interest rate risk is managed by ALCO, which is composed of certain members of the Liberty board, in accordance with policies approved by the Liberty board. The ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale activities, and the maturities of investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow flexibility, maturities of deposits and consumer and commercial deposit activity. Management uses two methodologies to manage interest rate risk: (i) an analysis of relationships between interest-earning assets and interest-bearing liabilities; and (ii) an interest rate shock simulation model.

Liberty uses an interest rate risk simulation model and shock analysis to test the interest rate sensitivity of net interest income and the balance sheet, respectively. Contractual maturities and repricing opportunities of

loans are incorporated in the model as are prepayment assumptions, maturity data and call options within the investment portfolio. Assumptions based on past experience are incorporated into the model for nonmaturity deposit accounts.

Liberty utilizes both static and dynamic balance sheet rate shocks to estimate the potential impact on net interest income of changes in interest rates under various rate scenarios. This analysis estimates a percentage of change in the metric from the stable rate base scenario versus alternative scenarios of rising and falling market interest rates by instantaneously shocking a static balance sheet. The following table summarizes the simulated change in net interest income over a 12-month horizon as of ~~June~~September 30, 2016 using a static balance sheet:

The following table summarizes the simulated change in net interest income over a 12-month horizon as of ~~June~~September 30, 2016 using a dynamic balance sheet:

The results are primarily due to behavior of demand, money market and savings deposits during such rate fluctuations. Liberty has found that, historically, interest rates on these deposits change more slowly than changes in the discount and federal funds rates. This assumption is incorporated into the simulation model and is generally not fully reflected in a gap analysis. The assumptions incorporated into the model are inherently uncertain and, as a result, the model cannot precisely measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and the application and timing of various strategies.

Net recoveries of ~~$696~~$649 thousand were recorded in the ~~six~~nine months ended ~~June~~September 30, 2016 compared to net charge-offs of ~~$690~~$570 thousand in the ~~six~~nine months ended ~~June~~September 30, 2015. A provision for loan losses was not recorded for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015. Net charge-offs of $546 thousand were recorded in the year ended December 31, 2015 compared to net recoveries of $439 thousand in the year ended December 31, 2014. A negative provision for loan losses of $917 thousand was recorded for the year ended December 31, 2014, while no provision was recorded for the year ended December 31, 2015.

At ~~June~~September 30, 2016, the allowance for loan and lease losses (the “ALLL”) which totaled $3.3 million consisted of ~~$49 thousand~~$-0- of specific reserves and ~~$3.24~~$3.3 million of general reserves, which compared to $65 thousand of specific reserves and $2.56 million of general reserves at December 31, 2015. At ~~June~~September 30, 2016, ~~$913~~$906 thousand of loan balances were individually evaluated for specific reserves compared to $2.5 million of loan balances at December 31, 2015. Substandard accruing loans of ~~$2.0~~$1.9 million at ~~June~~September 30, 2016 declined ~~$217~~$281 thousand from December 31, 2015 and substandard non-accruing balances of ~~$913~~$906 thousand at ~~June~~September 30, 2016 declined $1.6 million from December 31, 2015. At ~~June~~September 30, 2016 and December 31, 2015, one loan was classified as a troubled debt restructuring with a balance of ~~$913~~$906 thousand and $927 thousand, respectively.

At December 31, 2015, the allowance for loan and lease losses totaling $2.6 million consisted of $65 thousand of specific reserves and $2.56 million of general reserves, which compared to $69 thousand of specific reserves and $3.1 million of general reserves at December 31, 2014. At December 31, 2015, $2.5 million of loan balances were individually evaluated for specific reserves compared to $721 thousand of loan balances at December 31, 2014. Substandard accruing loans of $2.2 million at December 31, 2015 increased $809 thousand from December 31, 2014 and substandard non-accruing balances of $2.5 million at December 31, 2015 increased $1.8 million from December 31, 2014. At December 31, 2015, one loan was classified as a troubled debt restructuring totaling $927 thousand. At December 31, 2014, one loan was classified as a troubled debt restructuring totaling $120 thousand.

The following tables set forth the allocation of the allowance for loan losses as of the dates presented and the percentage of loans in each category to total loans. The purpose of this allocation is only for internal analysis of the adequacy of the allowance and is not an indication of expected or anticipated losses:

Although Liberty’s management believes that appropriate specific and general loan loss allowances have been established, actual losses are dependent upon future events and, therefore, further additions to the level of specific and general loan and lease loss allowances may become necessary.

General. Deposits, loan and investment security repayments and prepayments, proceeds from the sale of loans, and cash flows generated from operations are the primary sources of Liberty’s funds for lending, investing and other general purposes.

Deposits.Liberty offers a variety of deposit accounts with a range of interest rates and terms. Liberty’s core deposits consist of checking accounts, NOW accounts, money market accounts, savings accounts and certificates of deposit. These deposits are used to support Liberty’s asset base.

Liberty does not have any brokered deposits. Liberty has pledged cash in the amount of $4.5 million, $4.5 million and $4.7 million at ~~June~~September 30, 2016, December 31, 2015 and 2014, respectively against public fund deposits.

The following table sets forth the composition of deposits at the dates indicated:

The following table sets forth the maturities of Certificates of Deposit $100,000 and over at the dates indicated.

Borrowings.Liberty had no borrowings during the period January 1, 2014 through ~~June~~September 30, 2016.

Liberty does not currently engage in the use of derivative instruments to hedge interest rate risks. However, Liberty is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers.

At December 31, 2015 and 2014, Liberty had commitments to extend credit and unused line of credit totaling $25.9 and $22.2 million, respectively. At ~~June~~September 30, 2016, Liberty had ~~$36.5~~$31.3 million in commitments to

to extend credit and unused line of credit and $442 thousand in standby letters of credit. Commitments to extend credit are agreements to lend to a customer so long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by Liberty to guarantee the performance of a customer to a third party. Liberty uses the same credit policies in establishing commitments and issuing letters of credit as it does for on-balance sheet instruments.

Liquidity is the ability to meet present and future financial obligations through either the sale or maturity of existing assets or the acquisition of additional funds through liability management. Liquid assets include cash, federal funds sold, investments and loans maturing within one year. Liberty’s ability to obtain deposits and purchase funds at favorable rates determines its liquidity exposure. As a result of Liberty’s management of liquid assets and the ability to generate liquidity through liability funding, Liberty’s management believes that Liberty maintains overall liquidity sufficient to satisfy its depositors’ requirements and meet its customers’ credit needs.

Additional sources of liquidity available to Liberty include, but are not limited to, proceeds from principal and interest payments on loans and securities, the availability of federal funds, purchased lines from various correspondent banks and the ability to obtain deposits through the adjustment of interest rates. Growth in deposits has been sufficient to fund the majority of Liberty’s net increase in loans.

At ~~June~~September 30, 2016 and December 31, 2015, Liberty was in compliance with all of the capital requirements as established by federal regulatory agencies.

Liberty is subject to various requirements administered by the banking regulators. Failure to maintain minimum capital requirements can cause certain mandatory action by regulators that, if taken, could have a material effect. Under capital adequacy guidelines Liberty must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Liberty’s capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk factors and other factors.

At ~~June~~September 30, 2016 and December 31, 2015, Liberty’s capital was categorized as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since that time that management believes would have changed Liberty’s classification as well capitalized.

The following table sets forth the actual and required regulatory capital amounts and ratios for Liberty:

Liberty is subject to various regulatory policies and requirements relating to the payment of dividends, including requirements to maintain capital above regulatory minimums. In general, Liberty may not pay dividends in excess of its net earnings for the most recent three years. The payment of future dividends, if any, will depend primarily upon Liberty’s earnings, financial condition and need for funds, as well as restrictions imposed by regulatory authorities regarding dividend payments and net worth requirements. Liberty paid cash dividends on its common stock in the amount of ~~$0.40~~$0.60 per share for the ~~six~~nine months ended ~~June~~September 30, 2016. Liberty paid cash dividends on its common stock in the amount of $0.60 per share and $0.15 per share for the twelve months ended December 31, 2015 and 2014, respectively. Based upon ~~959,283~~960,273 shares outstanding at ~~June~~September 30, 2016, in connection with the Merger, Liberty expects to declare a special dividend of $3.13 per share or an aggregate of approximately $3.0 million. This may increase if any stock options are exercised before the special dividend is declared. Liberty believes that it will have sufficient liquid assets available.

The financial statements and related data presented herein have been prepared in accordance with generally accepted accounting principles in the United States of America, which require the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation. The primary impact of inflation on Liberty’s operations is reflected in increased operating costs. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than does inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

Middlefield. The consolidated financial statements of Middlefield appearing in Middlefield’s Annual Report on Form 10-K for the year ended December 31, 2015, have been audited by S.R. Snodgrass, P.C., independent auditor, as set forth in their report thereon included in the Annual Report and incorporated herein by reference. The consolidated financial statements are incorporated herein by reference in reliance upon the report given on the authority of S.R. Snodgrass, P.C. as experts in accounting and auditing.

Liberty. The consolidated financial statements of Liberty contained in this joint proxy statement/prospectus for the year ended December 31, 2015, have been audited by Maloney + Novotny LLC, independent auditor, as set forth in its report thereon and included herein. The consolidated financial statements are included herein in reliance upon that report given on the authority of Maloney + Novotny LLC as experts in accounting and auditing.

Grady & Associates has rendered an opinion that the Middlefield common stock to be issued to Liberty stockholders in the Merger is duly authorized and, if issued as provided in the Reorganization Agreement, will be validly issued, fully paid, and non-assessable under the laws of the State of Ohio. U.S. federal income tax consequences relating to the Merger will be passed upon for Liberty by Tucker Ellis LLP.

We have audited the accompanying consolidated balance sheet of Middlefield Banc Corp. and subsidiaries (the “Company”) as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income (loss), changes in stockholders’ equity, and cash flows for the three years in the period ended December 31, 2015. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Middlefield Banc Corp. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ending December 31, 2015, in conformity with U.S. Generally Accepted Accounting Principles.

A summary of the significant accounting and reporting policies applied in the presentation of the accompanying financial statements follows:

Middlefield Banc Corp. (the “Company”) is an Ohio corporation organized to become the holding company of The Middlefield Banking Company (“MBC”). MBC is a state-chartered bank located in Ohio. On April 19, 2007, Middlefield Banc Corp. acquired Emerald Bank (“EB”), an Ohio-chartered commercial bank headquartered in Dublin, Ohio. EB merged into MBC on January 20, 2014. On October 23, 2009, the Company established an asset resolution subsidiary named EMORECO, Inc. The Company and its subsidiaries derive substantially all of their income from banking and bank-related services, which includes interest earnings on residential real estate, commercial mortgage, commercial and consumer financings as well as interest earnings on investment securities and deposit services to its customers through ten locations. The Company is supervised by the Board of Governors of the Federal Reserve System, while MBC is subject to regulation and supervision by the Federal Deposit Insurance Corporation and the Ohio Division of Financial Institutions.

The consolidated financial statements of the Company include its wholly owned subsidiaries, MBC and EMORECO, Inc. Significant intercompany items have been eliminated in preparing the consolidated financial statements.

The financial statements have been prepared in conformity with U.S. Generally Accepted Accounting Principles. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ from those estimates.

Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale. Debt securities acquired with the intent and ability to hold to maturity are stated at cost adjusted for amortization of premium and accretion of discount, which are computed using a level yield method and recognized as adjustments of interest income. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity. Unrealized holding gains and losses for available-for-sale securities are reported as a separate component of stockholders’ equity, net of tax, until realized. Realized security gains and losses are computed using the specific identification method. Interest and dividends on investment securities are recognized as income when earned.

Securities are evaluated on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other than temporary. For debt securities, management considers whether the present value of cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Bank’s intent to sell the security or whether it is more likely than not that the Bank would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Bank does not intend to sell the security, and it is more likely than not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable

taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. For equity securities where the fair value has been significantly below cost for one year, the Bank’s policy is to recognize an impairment loss unless sufficient evidence is available that the decline is not other than temporary and a recovery period can be predicted.

Common stock of the Federal Home Loan Bank (“FHLB”) represents ownership in an institution that is wholly owned by other financial institutions. This equity security is accounted for at cost and classified with other assets. The FHLB of Cincinnati has reported profits for 2015 and 2014, remains in compliance with regulatory capital and liquidity requirements, and continues to pay dividends on the stock and make redemptions at the par value. With consideration given to these factors, management concluded that the stock was not impaired at December 31, 2015 or 2014.

Mortgage loans originated and intended for sale in the secondary market are carried at fair value. The Bank sells the loans on a servicing retained basis. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. The Bank measures servicing assets using the amortization method. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. Loan servicing rights are amortized in proportion to and over the period of estimated net future servicing revenue. The expected period of the estimated net servicing income is based in part on the expected prepayment of the underlying mortgages. The unamortized balance of mortgage servicing rights is included in accrued interest and other assets on the Consolidated Balance Sheet.

Mortgage servicing rights will be periodically evaluated for impairment, beginning in 2016. Impairment represents the excess of amortized cost over its estimated fair value. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as interest rate and original time to maturity. Any impairment is reported as a valuation allowance for an individual tranche. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance will be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of outstanding principal and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material.

The Company is exposed to interest rate risk on loans held for sale and rate-lock loan commitments (“IRLCs”). As market interest rates increase or decrease, the fair value of loans held for sale and rate-lock commitments will decrease or increase. The Company enters into derivative transactions principally to protect against the risk of adverse interest movements affecting the value of the Company’s committed loan sales pipeline. In order to mitigate the risk that a change in interest rates will result in a decrease in value of the Company’s IRLCs in the committed mortgage pipeline or its loans held for sale, the Company enters into mandatory forward loan sales contracts with secondary market participants. Mandatory forward sales contracts and committed loans intended to be held for sale are considered free-standing derivative instruments and changes in fair value are recorded in current period earnings. For committed loans, fair value is measured using current market rates for the associated mortgage loans. For mandatory forward sales contracts, fair value is measured using secondary market pricing.

losses. Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is recorded as income or applied against principal according to management’s judgment as to the collectability of such principal.

Loan origination fees and certain direct loan origination costs are being deferred and the net amount amortized as an adjustment of the related loan’s yield. Management is amortizing these amounts over the contractual life of the related loans.

The ~~SEC allows Middlefield~~allowance for loan and lease losses represents the amount which management estimates is adequate to ~~incorporate~~provide for probable loan losses inherent in the loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan and lease losses is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan and lease losses, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan and lease losses, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to significant change in the near term.

A loan is considered impaired when it is probable the borrower will not repay the loan according to the original contractual terms of the loan agreement. Management has determined that first mortgage loans on one-to-four family properties and all consumer loans represent large groups of smaller-balance homogeneous loans that are to be collectively evaluated. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. A loan is not impaired during a period of delay in payment if the Company expects to collect all amounts due, including interest accrued, at the contractual interest rate for the period of delay. All loans identified as impaired are evaluated independently by management. The Company estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan and lease losses is maintained for estimated losses. Cash receipts on impaired loans are applied first to accrued interest receivable unless otherwise required by the loan terms, except when an impaired loan is also a nonaccrual loan, in which case the portion of the payment related to interest is recognized as income.

Mortgage loans secured by one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Management determines the significance of payment delays on a case-by-case basis, taking into consideration all circumstances concerning the loan, the creditworthiness and payment history of the borrower, the length of the payment delay, and the amount of shortfall in relation to the principal and interest owed.

Land is carried at cost. Premises and equipment are stated at cost net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the assets, which range from 3 to 20 years for furniture, fixtures, and equipment and 3 to 40 years for buildings and leasehold improvements. Expenditures for maintenance and repairs are charged against income as incurred. Costs of major additions and improvements are capitalized.

The Company accounts for goodwill using a three-step process for testing the impairment of goodwill on at least an annual basis. This approach could cause more volatility in the Company’s reported net income because impairment losses, if any, could occur irregularly and in varying amounts. No impairment of goodwill was recognized in any of the periods presented.

Intangible assets include core deposit intangibles, which are a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases. The core deposit intangibles are being amortized to expense over a 10 year life on a straight-line basis. The recoverability of the carrying value of intangible assets is evaluated on an ongoing basis, and permanent declines in value, if any, are charged to expense.

The Company owns insurance on the lives of a certain ~~information into~~group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet and any increases in the cash surrender value are recorded as noninterest income on the Consolidated Statement of Income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit, which would be recorded as noninterest income.

Real estate properties acquired through foreclosure are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. After foreclosure, management periodically performs valuations and the real estate is carried at the lower of cost or fair value less estimated cost to sell. Revenue and expenses from operations of the properties, gains or losses on sales and additions to the valuation allowance are included in operating results.

The Company and its subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share are calculated utilizing net income as reported in the numerator and average shares outstanding in the denominator. The computation of diluted earnings per share differs in that the dilutive effects of any stock options, warrants, and convertible securities are adjusted in the denominator.

The Company accounts for stock compensation based on the grant date fair value of all share-based payment awards that are expected to vest, including employee share options to be recognized as employee compensation expense over the requisite service period.

For each of the years ended December 31, 2015, 2014, and 2013, the Company recorded no compensation cost related to vested stock options. As of December 31, 2015, there was no unrecognized compensation cost related to unvested stock options.

At year ended December 31, 2015, 585 shares of restricted stock were awarded and immediately vested. There were no shares of restricted stock issued in 2014 or 2013.

For the years ended December 31, 2015 and 2014, 2,175 and 11,223 options were exercised resulting in net proceeds to the participant of $7,000 and $50,000, respectively.

The Company has defined cash and cash equivalents as those amounts included in the Consolidated Balance Sheet captions as “Cash and due from banks” and “Federal funds sold” with original maturities of less than 90 days.

Certain comparative amounts for prior years have been reclassified to conform to current-year presentations. Such reclassifications did not affect net income or retained earnings.

In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-01,Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects.The amendments in this ~~document~~Update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this Update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. This Update did not have a significant impact on the Company’s financial statements.

In January 2014, the FASB issued ASU 2014-04,Receivables – Troubled Debt Restructurings by ~~reference~~Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.The amendments in this Update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to ~~other information filed~~have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by ~~Middlefield~~the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. This Update did not have a significant impact on the Company’s financial statements.

In May 2014, the FASB issued ASU 2014-09,Revenue from Contracts with Customers (a new revenue recognition standard). The Update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This Update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is evaluating the effect of adopting this new accounting Update.

In June 2014, the FASB issued ASU 2014-11,Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this Update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this Update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Earlier application is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. This Update did not have a significant impact on the Company’s financial statements.

In June 2014, the FASB issued ASU 2014-12,Compensation– Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period.The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this Update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This Update is not expected to have a significant impact on the Company’s financial statements.

In August 2014, the FASB issued ASU 2014-14,Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40). The amendments in this Update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. This Update did not have a significant impact on the Company’s financial statements.

In November 2014, the FASB issued ASU 2014-17,Business Combinations (Topic 805): Pushdown Accounting.The amendments in this Update apply to the separate financial statements of an acquired entity and its

subsidiaries that are a business or nonprofit activity (either public or nonpublic) upon the occurrence of an event in which an acquirer (an individual or an entity) obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity’s most recent change-in-control event. The amendments in this Update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. This Update is not expected to have a significant impact on the Company’s financial statements.

In February 2015, the FASB issued ASU 2015-02,Consolidation (Topic 810). The amendments in this Update affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related-party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in this Update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017. This Update is not expected to have a significant impact on the Company’s financial statements.

In April 2015, the FASB issued ASU 2015-05,Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40), as part of its initiative to reduce complexity in accounting standards. This guidance will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The amendments in this Update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. For public business entities, the FASB decided that the amendments will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. For all other entities, the amendments will be effective for annual periods beginning after December 15, 2015, and interim periods in annual periods beginning after December 15, 2016. Early adoption is permitted for all entities. This Update is not expected to have a significant impact on the Company’s financial statements.

In May 2015, the FASB issued ASU 2015-08, Business Combinations – Pushdown Accounting – Amendment to SEC ~~(File~~Paragraphs Pursuant to Staff Accounting Bulletin No. ~~001-36613)~~115. This ~~means~~Update was issued to amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115. This Update is not expected to have a significant impact on the Company’s financial statements.

In June 2015, the FASB issued ASU 2015-10,Technical Corrections and Improvements. The amendments in this Update represent changes to clarify the FASB Accounting Standards Codification (“Codification”), correct unintended application of guidance, or make minor improvements to the Codification that ~~Middlefield can~~are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Transition guidance varies based on the amendments in this Update. The amendments in this Update that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon the issuance of this Update. This Update is not expected to have a significant impact on the Company’s financial statements.

In August 2015, the FASB issued ASU 2015-14,Revenue from Contract with Customers (Topic 606). The amendments in this Update defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. The Company is evaluating the effect of adopting this new accounting Update.

In September 2015, the FASB issued ASU 2015-16,Business Combinations (Topic 805). The amendments in this Update require that an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this Update require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this Update require an entity to present separately on the face of the income statement or disclose ~~important~~in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. This Update is not expected to have a significant impact on the Company’s financial statements.

In November 2015, the FASB issued ASU 2015-17,Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. For all other entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The amendments in this Update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. This Update is not expected to have a significant impact on the Company’s financial statements.

In January 2016, the FASB issued ASU 2016-01,Financial Instruments – Overall (Subtopic 825-10):Recognition and Measurement of Financial Assets and Financial Liabilities. This Update applies to all entities that hold financial assets or owe financial liabilities and is intended to provide more useful information on the recognition, measurement, presentation, and disclosure of financial instruments. Among other things, this Update (a) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (b) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (d) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (e) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (f) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (g) requires separate presentation of

financial assets and financial ~~information~~liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to ~~you by referring you~~the financial statements; and (h) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to ~~another document filed separately~~available-for-sale securities in combination with the ~~SEC. The information that Middlefield incorporates by reference is deemed to be part of this joint proxy statement/prospectus, except for any information that is superseded by information~~entity’s other deferred tax assets. For public business entities, the amendments in this ~~document. The documents incorporated by reference contain important information about Middlefield. You should read this document together with any~~Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other ~~documents incorporated by reference~~entities including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this ~~document. This document incorporates~~Update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

There are no convertible securities that would affect the numerator in calculating basic and diluted earnings per share; therefore, net income as presented on the Consolidated Statement of Income will be used as the numerator. The following table sets forth the composition of the weighted-average common shares (denominator) used in the basic and diluted earnings per share computation for the year ended December 31.

Options to purchase 31,949 shares of common stock at prices ranging from $17.55 to $40.24 were outstanding during the year ended December 31, 2015. Of those options, 27,250 were considered dilutive based on the average market price exceeding the strike price for the year ended December 31, 2015. The remaining options had no dilutive effect on the earnings per share.

Options to purchase 46,451 shares of common stock at prices ranging from $17.55 to $40.24 were outstanding during the year ended December 31, 2014. Of those options, 28,282 were considered dilutive based on the average market price exceeding the strike price for the year ended December 31, 2014. The remaining options had no dilutive effect on the earnings per share.

Options to purchase 58,581 shares of common stock at prices ranging from $17.55 to $40.24 were outstanding during the year ended December 31, 2013. Of those options, 39,808 were considered dilutive based on the average market price exceeding the strike price for the year ended December 31, 2013. The remaining options had no dilutive effect on the earnings per share.

The amortized cost and fair values of securities available for sale are as follows:

The amortized cost and fair value of debt securities at December 31, 2015, by ~~reference~~contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investment securities with an approximate carrying value of $68.8 million and $61.9 million at December 31, 2015 and 2014, respectively, were pledged to secure deposits and other purposes as required by law.

Proceeds from the sales of securities available for sale and the gross realized gains and losses for the years ended December, 31 are as follows (in thousands):

The following tables show the Company’s gross unrealized losses and fair value, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position.

There were 46 securities that were considered temporarily impaired at December 31, 2015.

On a quarterly basis, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment (“OTTI”). A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The accounting literature requires the Company to assess whether the unrealized loss is other than temporary. For equity securities where the fair value has been significantly below cost for one year, the Company’s policy is to recognize an impairment loss unless sufficient evidence is available that the decline is not other than temporary and a recovery period can be predicted.

The Company has asserted that at December 31, 2015 and 2014, the declines outlined in the above table represent temporary declines and the Company does not intend to sell and does not believe it will be required to sell these securities before recovery of their cost basis, which may be at maturity. The Company has concluded that any impairment of its investment securities portfolio outlined in the above table is not other than temporary and is the result of interest rate changes, sector credit rating changes, or company-specific rating changes that are not expected to result in the non-collection of principal and interest during the period.

Debt securities issued by U.S. government agencies, U.S. government-sponsored enterprises, and state and political subdivisions accounted for more than 97.9% of the total available-for-sale portfolio as of December 31, 2015, and no credit losses are expected, given the explicit and implicit guarantees provided by the U.S. federal government and the lack of significant unrealized loss positions within the obligations of state and political subdivisions security portfolio. The Company evaluates credit losses on a quarterly basis. The Company considered the following ~~documents previously filed by Middlefield with~~factors in determining whether a credit loss exists and the ~~SEC:~~period over which the debt security is expected to recover:

Major classifications of loans at December 31 are summarized as follows (in thousands):

The Company’s primary business activity is with customers located within its local trade area, eastern Geauga County, and contiguous counties to the north, east, and south. The Company also serves the central Ohio market with offices in Dublin and Westerville, Ohio. Commercial, residential, consumer, and agricultural loans are granted. Although the Company has a diversified loan portfolio at December 31, 2015 and 2014, loans outstanding to individuals and businesses are dependent upon the local economic conditions in its immediate trade area.

The following tables summarize the primary segments of the loan portfolio and the allowance for loan and lease losses as of December 31, 2015 and 2014 (in thousands):

The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into Commercial and Industrial (“C&I”), Real Estate Construction, Real Estate—Mortgage which is further segmented into Residential and Commercial real estate, and Consumer Installment Loans. The C&I loan segment consists of loans made for the purpose of financing the activities of commercial customers. The residential mortgage loan segment consists of loans made for the purpose of financing the activities of residential homeowners. The commercial mortgage loan segment consists of loans made for the purpose of financing the activities of commercial real estate owners and operators. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts.

Management evaluates individual loans in all of the commercial segments for possible impairment if the loan is greater than $150,000 and if the loan either is in nonaccrual status, or is risk rated Substandard or Doubtful and is greater than 90 days past due. Loans are considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in

evaluating impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company does not separately evaluate individual consumer and residential mortgage loans for impairment, unless such loans are part of a larger relationship that is impaired.

Once the determination has been made that a loan is impaired, the determination of whether a specific allocation of the allowance is necessary is measured by comparing the recorded investment in the loan to the fair value of the loan using one of three methods: (a) the present value of expected future cash flows discounted at the loan’s effective interest rate; (b) the loan’s observable market price; or (c) the fair value of the collateral less selling costs. The method is selected on a loan-by-loan basis, with management primarily utilizing the fair value of collateral method. The evaluation of the need and amount of a specific allocation of the allowance and whether a loan can be removed from impairment status is made on a quarterly basis. The Company’s policy for recognizing interest income on impaired loans does not differ from its overall policy for interest recognition.

The following tables present impaired loans by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary (in thousands):

The tables above include troubled debt restructuring totaling $3.1 million and $2.9 million as of December 31, 2015 and 2014, respectively.

The following table presents interest income by class, recognized on impaired loans (in thousands):

Troubled Debt Restructuring (TDR) describes loans on which the bank has granted concessions for reasons related to the customer’s financial difficulties. Such concessions may include one or more of the following:

In each case the concession is made due to deterioration in the borrower’s financial condition, and the new terms are less stringent than those required on a new loan with similar risk.

The following tables present the number of loan modifications by class, the corresponding recorded investment, and the subsequently defaulted modifications (in thousands):

rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a Substandard classification. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans greater than 90 days past due are considered Substandard. Any portion of a loan that has been charged off is placed in the Loss category.

To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan-rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death, occurs to raise awareness of a possible credit event. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis with the Chief Credit Officer ultimately responsible for accurate and timely risk ratings. The Credit Department performs an annual review of all commercial relationships $1,000,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Company engages an external consultant to conduct loan reviews on a semiannual basis. Generally, the external consultant reviews commercial relationships greater than $250,000 and/or criticized relationships greater than $125,000. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.

The following tables present the classes of the loan portfolio summarized by the aggregate Pass rating and the criticized categories of Special Mention, Substandard, and Doubtful within the internal risk rating system as of December 31, 2015 and 2014 (in thousands):

Management further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by the length of time a recorded payment is past due. The following tables present the classes of the loan portfolio summarized by the aging categories of loans and nonaccrual loans as of December 31, 2015 and 2014 (in thousands):

The following tables present the classes of the loan portfolio summarized by nonaccrual loans and loans 90 days or more past due and still accruing as of December 31, 2015 and 2014 (in thousands):

Interest income that would have been recorded had these loans not been placed on nonaccrual status was $259,000 in 2015, $207,000 in 2014, and $439,000 in 2013.

An allowance for loan and lease losses (“ALLL”) is maintained to absorb losses from the loan portfolio. The ALLL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated loss experience, and the amount of nonperforming loans.

The Company’s methodology for determining the ALLL is based on the requirements of ASC Section 310-10-35 for loans individually evaluated for impairment (discussed above) and ASC Subtopic 450-20 for loans collectively evaluated for impairment, as well as the Interagency Policy Statement on the Allowance for Loan and Lease Losses and other bank regulatory guidance. The total of the two components represents the Company’s ALLL.

Loans that are collectively evaluated for impairment are analyzed, with general allowances being made as appropriate. For general allowances, historical loss trends are used in the estimation of losses in the current portfolio. These historical loss amounts are modified by other qualitative factors.

The classes described above, which are based on the purpose code assigned to each loan, provide the starting point for the ALLL analysis. Management tracks the historical net charge-off activity at the purpose code level. A historical charge-off factor is calculated utilizing the last twelve consecutive quarters.

Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor, because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience. The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and nonaccrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry, and/or geographic standpoint.

Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the ALLL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALLL.

The following tables summarize the primary segments of the loan portfolio (in thousands):


	Commercial and industrial			Real estate- construction			Real estate- residential mortgage			Real estate- commercial mortgage		Consumer installment			Total
ALLL balance at December 31, 2012	$	1,732		$	1,123		$	2,872		$	1,991	$	61		$	7,779
Charge-offs		(419	)		(191	)		(675	)		—		(45	)		(1,330	)
Recoveries		191			33			107			46		24			401
Provision		(890	)		(389	)		1,360			133		(18	)		196

ALLL balance at December 31, 2013	$	614		$	576		$	3,664		$	2,170	$	22		$	7,046

The decrease in the ALLL balance for real estate construction was largely due to a $0.4 million charge off. The decrease in the ALLL balance for residential real estate was largely due to aggregate charge offs of $0.3 million of loans secured by first liens. The increase in the ALLL balance for commercial real estate is mostly due to the 21.5% growth in the portfolio.

OREO comprises foreclosed assets acquired in settlement of loans and is carried at fair value less estimated cost to sell and is included in other assets on the Consolidated Balance Sheet. As of December 31, 2015, and December 31, 2014, there were $1.4 million and $2.6 million, respectively, of OREO. As of December 31, 2015, the Company has initiated formal foreclosure proceedings on $1.1 million of real estate.

Depreciation and amortization charged to operations was $715,000 in 2015, $750,000 in 2014, and $676,000 in 2013.

Goodwill totaled $4,559,000 at the years ended December 31, 2015, and 2014. Core deposit intangible carrying amount was $76,000 and $116,000 for the years ended December 31, 2015, and 2014. Core deposit accumulated amortization was $320,000 and $280,000 for the years ended December 31, 2015, and 2014.

Core deposit intangible assets are amortized on a straight-line basis over their estimated lives of ten years. Amortization expense totaled $40,000 in 2015, 2014, and 2013, respectively. The estimated aggregate future amortization expense for core deposit intangible assets as of December 31, 2015, is $40,000 in 2017 and $36,000 in 2018.

Time deposits at December 31, 2015, mature $92.9 million, $30.2 million, $11.0 million, $9.0 million, and $48.2 million during 2016, 2017, 2018, 2019, and 2020, respectively.

The aggregate of all time deposit accounts of $250,000 or more amounted to $29.0 million and $54.6 million at December 31, 2015 and 2014, respectively.

The year ended December 31 outstanding balances and related information of short-term borrowings, which includes securities sold under agreements to repurchase and short-term borrowings from other banks, are summarized as follows:

Average balances outstanding during the year represent daily average balances, and average interest rates represent interest expense divided by the related average balance.

The Company maintains a $4.0 million line of credit at an adjustable rate, currently 3.92%, a $3.0 million line of credit at an adjustable rate, currently at 4.00%, and a $2.5 million line of credit at an adjustable rate, currently 3.75%. At December 31, 2015, 2014, and 2013, outstanding borrowings under these lines were $9.5 million, $3.1 million, and $3.9 million, respectively.

The following table provides additional detail regarding short-term borrowed funds.

Other borrowings consist of advances from the FHLB and subordinated debt as follows:

Fixed-rate amortizing advances from the FHLB require monthly principal and interest payments and an annual 20 percent paydown of outstanding principal. Monthly principal and interest payments are adjusted after each 20 percent paydown. Under the terms of a blanket agreement, FHLB borrowings are secured by certain qualifying assets of the Company which consist principally of first mortgage loans or mortgage-backed securities. Under this credit arrangement, the Company has a remaining borrowing capacity of approximately $80.0 million at December 31, 2015.

The Company formed a special purpose entity (“Entity”) to issue $8,000,000 of floating rate, obligated mandatorily redeemable securities, and $248,000 in common securities as part of a pooled offering. The rate adjusts quarterly, equal to LIBOR plus 1.67%. The Entity may redeem them, in whole or in part, at face value. The Company borrowed the proceeds of the issuance from the Entity in December 2006 in the form of an $8,248,000 note payable, which is included in the other borrowings on the Company’s Consolidated Balance Sheet.

The tax effects of deductible and taxable temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows:

No valuation allowance was established at December 31, 2015 and 2014, in view of the Company’s ability to carry back to taxes paid in previous years and certain tax strategies, coupled with the anticipated future taxable income as evidenced by the Company’s earnings potential.

The reconciliation between the federal statutory rate and the Company’s effective consolidated income tax rate is as follows:

ASC 740-10 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met.

At December 31, 2015 and December 31, 2014, the Company had no unrecognized tax benefits. The Company does not expect the total amount of unrecognized tax benefits to significantly increase within the next 12 months. The Company recognizes interest and penalties on unrecognized tax benefits as a component of income tax expense.

The Company and the Bank are subject to U.S. federal income tax as well as an income tax in the state of Ohio, and the Bank is subject to a capital-based franchise tax in the state of Ohio. The Company and the Bank are no longer subject to examination by taxing authorities for years before December 31, 2012.

The Bank maintains section 401(k) employee savings and investment plans for all full-time employees and officers of the Bank with more than one year of service. The Bank’s contributions to the plans are based on 50 percent matching of voluntary contributions up to 6 percent of compensation. An eligible employee can contribute up to 100 percent of salary. Employee contributions are vested at all times, and MBC contributions are fully vested after six years beginning at the second year in 20 percent increments. Contributions for 2015, 2014, and 2013 to these plans amounted to $156,000, $143,000, and $155,000, respectively.

Until 2001, MBC maintained a Directors’ Retirement Plan to provide postretirement payments over a ten-year period to members of the Board of Directors who had completed five or more years of service. The plan required payment of 25 percent of the final average annual board fees paid to a director in the three years preceding the director’s retirement.

The following table illustrates the components of the projected payments for the Directors’ Retirement Plan for the years ended:

The retirement plan is available solely for nonemployee directors of The Middlefield Banking Company, but the Bank has not entered into any additional retirement arrangements for nonemployee directors since 2001. All director participants have retired.

The Company maintains an Executive Deferred Compensation Plan (the “Plan”) to provide post-retirement payments to members of senior management. The Plan agreements are noncontributory, defined contribution arrangements that provide supplemental retirement income benefits to several officers, with contributions made solely by the Bank. During 2015, 2014, and 2013, the Company contributed $65,000, $115,000, and $120,000, respectively, to the Plan.

The Company maintains a stock option and restricted stock plan (“the Plan”) for granting incentive stock options, nonqualified stock options, and restricted stock to key officers and employees and nonemployee directors of the Company. A total of 160,000 shares of authorized and unissued or issued common stock were reserved for issuance under the Plan, which expires ten years from the date of stockholder ratification. The per share exercise price of an option granted will not be less than the fair value of a share of common stock on the date the option is granted.

The following table summarizes the characteristics of stock options at December 31, 2015:

No options were granted for the years ended December 31, 2015 and 2014. The Company recognizes compensation expense in the amount of fair value of the common stock at the grant date and as an addition to stockholders’ equity.

In the normal course of business, there are various outstanding commitments and certain contingent liabilities which are not reflected in the accompanying consolidated financial statements. These commitments and

contingent liabilities represent financial instruments with off-balance sheet risk. The contract or notional amounts of those instruments reflect the extent of involvement in particular types of financial instruments which were composed of the following:

These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheet. The Company’s exposure to credit loss, in the event of nonperformance by the other parties to the financial instruments, is represented by the contractual amounts as disclosed. The Company minimizes its exposure to credit loss under these commitments by subjecting them to credit approval and review procedures and collateral requirements as deemed necessary. Commitments generally have fixed expiration dates within one year of their origination.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Performance letters of credit represent conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These instruments are issued primarily to support bid or performance-related contracts. The coverage period for these instruments is typically a one-year period with an annual renewal option subject to prior approval by management. Fees earned from the issuance of these letters are recognized over the coverage period. For secured letters of credit, the collateral is typically bank deposit instruments or customer business assets.

Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward contracts for the future delivery of these mortgage loans are considered derivatives. It is the Company’s practice to enter into the forward contracts for the future purchase of mortgage-backed securities when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not formally designated as hedge relationships. The derivative assets and liabilities are considered immaterial as of December 31, 2015. Associated income and expense is reported in gains on sale of loans.

The Company leases certain of its banking facilities under operating leases which contain certain renewal options. As of December 31, 2015, approximate future minimum rental payments, including the renewal options under these leases, are as follows (in thousands):

The above amounts represent minimum rentals not adjusted for possible future increases due to escalation provisions and assume that all renewal option periods will be exercised by the Company. Rent expense approximated $288,000, $269,000, and $301,000 for the years ended December 31, 2015, 2014, and 2013, respectively.

The Company is subject to the regulatory requirements of the Federal Reserve System as a bank holding company. The bank is subject to regulations of the Federal Deposit Insurance Corporation (“FDIC”) and the State of Ohio, Division of Financial Institutions.

Since the establishment in the fourth quarter of 2009 of Middlefield Banc Corp.’s nonbank-asset resolution subsidiary, EMORECO, Inc., the Bank has sold $5.8 million of nonperforming assets to this subsidiary.

The Cleveland district Federal Reserve Bank requires the Company to maintain certain average reserve balances. As of December 31, 2015 and 2014, the Bank had required reserves of $6.9 million and $6.8 million comprising vault cash and a depository amount held with the Federal Reserve Bank.

Federal law prevents the Company from borrowing from the Bank unless the loans are secured by specific obligations. Further, such secured loans are limited in amount of 10 percent of the Bank’s common stock and capital surplus.

MBC is subject to dividend restrictions that generally limit the amount of dividends that can be paid by an Ohio state-chartered bank. Under the Ohio Banking Code, cash dividends may not exceed net profits as defined for that year combined with retained net profits for the two preceding years less any required transfers to surplus. Under this formula the amount available for payment of dividends for 2015 approximates $8.5 million plus 2016 profits retained up to the date of the dividend declaration. As a condition to the ODFI’s approval of the merger of Emerald Bank into MBC, until the third anniversary of the merger, that is until January 20, 2017, MBC will have to obtain the ODFI’s advance approval for dividend payments to the Company.

The Bank and Company are subject to regulatory capital requirements administered by banking agencies. Capital adequacy guidelines and prompt corrective-action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings, and other factors and the regulators can lower classifications in certain cases. Failure to meet various capital requirements can initiate regulatory action that could have a direct material effect on the financial statements. Management believes as of December 31, 2015, the Bank and Company have met all capital adequacy requirements to which it is subject.

The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, under-capitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and plans for capital restoration are required.

The Basel III Capital Rules became effective for the Bank on January 1, 2015 and certain provisions are subject to a phase-in period. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased in over a four -year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital

buffer” that is applicable to only certain covered institutions and does not have any current applicability to the Bank. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets above the minimum but below the conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall.

The following tables present actual and required capital ratios as of December 31, 2015 under the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules.

See Note 15 for additional information concerning regulatory capital requirements

The Company’s and its subsidiary’s actual capital ratios are presented in the following table that shows that all regulatory capital requirements were met as of December 31, 2014.

The following disclosures show the hierarchal disclosure framework associated with the level of pricing observations utilized in measuring assets and liabilities at fair value. The three broad levels defined by U.S. generally accepted accounting principles are as follows:

The following tables present the assets measured on a recurring basis on the Consolidated Balance Sheet at their fair value as of December 31, 2015 and 2014, by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Financial instruments are considered Level III when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. In addition to these unobservable inputs, the valuation models for Level III financial instruments typically also rely on a number of inputs that are readily observable either directly or indirectly. Level III financial instruments also include those for which the determination of fair value requires significant management judgment or estimation.

The following tables present the assets measured on a non-recurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Impaired loans that are collateral dependent are written down to fair value through the establishment of specific reserves. Techniques used to value the collateral that secure the impaired loan include quoted market prices for identical assets classified as Level I inputs and observable inputs, employed by certified appraisers, for similar assets classified as Level II inputs. In cases where valuation techniques included inputs that are unobservable and are based on estimates and assumptions developed by management based on the best information available under each circumstance, the asset valuation is classified as Level III inputs.

Assets measured on a non-recurring basis:
Impaired loans	$	—	$	—	$	12,772	$	12,772

The following tables present additional quantitative information about assets measured at fair value on a non-recurring basis and for which the Company uses Level III inputs to determine fair value:

The estimated fair value of the Company’s financial instruments is as follows:

Financial instruments are defined as cash, evidence of ownership interest in an entity, or a contract which creates an obligation or right to receive or deliver cash or another financial instrument from/to a second entity on potentially favorable or unfavorable terms.

Fair value is defined as the amount at which a financial instrument could be exchanged in a current transaction between willing parties other than in a forced liquidation sale. If a quoted market price is available for a financial instrument, the estimated fair value would be calculated based upon the market price per trading unit of the instrument.

If no readily available market exists, the fair value estimates for financial instruments should be based upon management’s judgment regarding current economic conditions, interest rate risk, expected cash flows, future estimated losses, and other factors as determined through various option pricing formulas or simulation modeling. Since many of these assumptions result from judgments made by management based upon estimates which are inherently uncertain, the resulting estimated fair values may not be indicative of the amount realizable in the sale of a particular financial instrument. In addition, changes in assumptions on which the estimated fair values are based may have a significant impact on the resulting estimated fair values.

As certain assets such as deferred tax assets and premises and equipment are not considered financial instruments, the estimated fair value of financial instruments would not represent the full value of the Company.

The Company employed simulation modeling in determining the estimated fair value of financial instruments for which quoted market prices were not available based upon the following assumptions.

Cash and Cash Equivalents, Federal Home Loan Bank Stock, Accrued Interest Receivable, Accrued Interest Payable, and Short-Term Borrowings

The fair value is equal to the cash surrender value of the life insurance policies.

The fair value of investment securities is equal to the available quoted market price. If no quoted market price is available, fair value is estimated using the quoted market price for similar securities.

The fair value is estimated by discounting future cash flows using current market inputs at which loans with similar terms and qualities would be made to borrowers of similar credit quality. Where quoted market prices were available, primarily for certain residential mortgage loans, such market rates were utilized as estimates for fair value.

Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using security prices for similar product types and, therefore, are classified in Level II.

The fair values of certificates of deposit and other borrowed funds are based on the discounted value of contractual cash flows. The discount rates are estimated using rates currently offered for similar instruments with similar remaining maturities. Demand, savings, and money market deposits are valued at the amount payable on demand as of year-end.

These financial instruments are generally not subject to sale, and estimated fair values are not readily available. The carrying value, represented by the net deferred fee arising from the unrecognized commitment or letter of credit, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, are not considered material for disclosure. The contractual amounts of unfunded commitments and letters of credit are presented in Note 14.

The following table presents the changes in accumulated other comprehensive income (loss) by component net of tax:

The following tables present significant amounts reclassified out of each component of accumulated other comprehensive income (loss):

The consolidated financial statements of Middlefield Banc Corp. (“Company”) include its bank subsidiary, The Middlefield Banking Company (“MB”), and a nonbank asset resolution subsidiary EMORECO, Inc. All significant inter-company items have been eliminated.

The accompanying unaudited financial statements have been prepared in accordance with U.S. generally accepted accounting principles and the instructions for Form 10-Q and Article 10 of Regulation S-X. In management’s opinion, the financial statements include all adjustments, consisting of normal recurring adjustments, that the Company considers necessary to fairly state the Company’s financial position and the results of operations and cash flows. The consolidated balance sheet at December 31, 2015, has been derived from the audited financial statements at that date but does not include all of the necessary informational disclosures and footnotes as required by U.S. generally accepted accounting principles. The accompanying financial statements should be read in conjunction with the financial statements and notes thereto included with the Company’s Form 10-K for the year ended December 31, 2015. The results of the Company’s operations for any interim period are not necessarily indicative of the results of the Company’s operations for any other interim period or for a full fiscal year.

In May 2014, the FASB issued ASU 2014-09,Revenue from Contracts with Customers (a new revenue recognition standard). The Update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this Update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This Update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In June 2014, the FASB issued ASU 2014-12,Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this Update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This Update is not expected to have a significant impact on the Company’s financial statements, or the Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In August 2015, ~~filed March 9,~~the FASB issued ASU 2015-14,Revenue from Contracts with Customers (Topic 606). The amendments in this Update defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting

periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. The Company is evaluating the effect of adopting this new accounting Update.

~~Quarterly Report~~ the FASB issued ASU 2016-01,Financial Instruments – Overall (Subtopic 825-10):Recognition and Measurement of Financial Assets and Financial Liabilities. This Update applies to all entities that hold financial assets or owe financial liabilities and is intended to provide more useful information on ~~Form 10-Q~~the recognition, measurement, presentation, and disclosure of financial instruments. Among other things, this Update (a) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (b) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (d) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (e) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (f) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (g) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (h) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other entities, including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In February 2016, the FASB issued ASU 2016-02,Leases (Topic 842). The standard requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. A short-term lease is defined as one in which (a) the lease term is 12 months or less and (b) there is not an option to purchase the underlying asset that the lessee is reasonably certain to exercise. For short-term leases, lessees may elect to recognize lease payments over the lease term on a straight-line basis. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those years. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and for interim periods within fiscal years beginning after December 15, 2020. The amendments should be applied at the beginning of the earliest period ~~ended~~presented using a modified retrospective approach with earlier application permitted as of the beginning of an interim or annual reporting period. This Update is not expected to have a significant impact on the Company’s financial statements.

In March ~~31,~~ 2016, ~~filed May 11,~~the FASB issued ASU 2016-04,Liabilities–Extinguishments of Liabilities (Subtopic 405-20).The standard provides that liabilities related to the sale of prepaid stored-value products within the scope of this Update are financial liabilities. The amendments in the Update provide a narrow-scope exception to the guidance in Subtopic 405-20 to require that breakage for those liabilities be accounted for consistent with the breakage guidance in Topic 606. The amendments in this Update are effective for public business entities, certain not-for-

profit entities, and certain employee benefit plans for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Earlier application is permitted, including adoption in an interim period. This Update is not expected to have a significant impact on the Company’s financial statements.

In March 2016,

~~Quarterly Report~~ the FASB issued ASU 2016-05,Derivatives and Hedging (Topic 815). The amendments in this Update apply to all reporting entities for which there is a change in the counterparty to a derivative instrument that has been designated as a heading instrument under Topic 815. The standards in this Update clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. For all other entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2018. An entity has an option to apply the amendments in this Update on ~~Form 10-Q~~either a prospective basis or a modified retrospective basis. Early adoption is permitted, including adoption in an interim period. This Update is not expected to have a significant impact on the Company’s financial statements.

In March 2016, the FASB issued ASU 2016-06,Derivatives and Hedging (Topic 815). The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt host. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. For entities other than public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. This Update is not expected to have a significant impact on the Company’s financial statements.

In March 2016, the FASB issued ASU 2016-07,Investments–Equity Method and Joint Ventures (Topic 323). The Update affects all entities that have an investment that becomes qualified for the ~~period ended June 30, 2016, filed August 10, 2016~~

~~In addition, Middlefield is incorporating by reference any documents it may file under Section 13 (a), 13(c), 14~~level of ownership interest or ~~15(d)~~degree of influence. The amendments in this Update eliminate the requirement that when an investment qualifies for use of the ~~Securities Exchange Act~~equity method as a result of ~~1934 after the date of this document and before the date of each company’s meeting of stockholders.~~

Middlefield files annual, quarterly and special reports, proxy statements and other business and financial information with the SEC. You may obtain the information incorporated by reference and any other materials Middlefield files with the SEC without charge by following the instructionsan increase in the ~~section entitled “~~~~WHERE YOU CAN FIND MORE INFORMATION~~”level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the ~~forepart of this document.~~

~~Neither Middlefield nor Liberty has authorized anyone~~investee to ~~give any information or make any representation about~~ the ~~Merger that is different from or in addition to that contained in this document or in any~~current basis of the ~~materials incorporated into this document. Therefore, if anyone does give you information~~investor’s previously held interest and adopt the equity method of this sort, you should not rely on it. If you are in a jurisdiction where offers to exchange or sell or solicitations of offers to exchange or purchase the securities offered by this document or the solicitation of proxies is unlawful, or if you are a person to whom it is unlawful to direct these types of activities, then the offer presented in this document does not extend to you. The information contained in this document is given solelyaccounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this ~~document~~Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.

In March 2016, the FASB issued ASU 2016-08,Revenue from Contracts with Customers (Topic 606).The amendments in this Update affect entities with transactions included within the scope of Topic 606, which

includes entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this Update do not change the core principle of the guidance in Topic 606; they simply clarify the implementation guidance on principal versus agent considerations. The amendments in this Update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in this Update affect the guidance in ASU 2014-09,Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements of Update 2014-09. ASU No. 2015-14,Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,defers the effective date of Update 2014-09 by one year. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In March 2016, the FASB issued ASU 2016-09,Compensation – Stock Compensation (Topic 718). The amendments in this Update affect all entities that issue share-based payment awards to their employees. The standards in this Update provide simplification for several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as with equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. In addition to those simplifications, the amendments eliminate the guidance in Topic 718 that was indefinitely deferred shortly after the issuance of FASB Statement No. 123 (revised 2004),Share-Based Payment. This should not result in a change in practice because the guidance that is being superseded was never effective. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. For all other entities, the amendments are effective for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. Early adoption is permitted for any entity in any interim or annual period. This Update is not expected to have a significant impact on the Company’s financial statements.

In April 2016, the FASB issued ASU 2016-10,Revenue from Contracts with Customers (Topic 606). The amendments in this Update affect entities with transactions included within the scope of Topic 606, which includes entities that enter into contracts with customers to transfer goods or services in exchange for consideration. The amendments in this Update do not change the core principle for revenue recognition in Topic 606. Instead, the amendments provide (1) more detailed guidance in a few areas and (2) additional implementation guidance and examples based on feedback the FASB received from its stakeholders. The amendments are expected to reduce the degree of judgment necessary to comply with Topic 606, which the FASB expects will reduce the potential for diversity arising in practice and reduce the cost and complexity of applying the guidance. The amendments in this Update affect the guidance in ASU 2014-09,Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). ASU 2015-14,Revenue from Contracts with Customers (Topic 606):Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In May 2016, the FASB issued ASU 2016-11, Revenue Recognition (Topic 605) and Derivative and Hedging (Topic 815), which rescinds SEC paragraphs pursuant to two SEC Staff Announcements at the March 3, 2016, Emerging Issues Task Force meeting. This Update did not have a significant impact on the Company’s financial statements.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606), which among other things clarifies the objective of the collectability criterion in Topic 606, as well as certain narrow aspects of Topic 606. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606

(and any other Topic amended by Update 2014-09). ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. This Update is not expected to have a significant impact on the Company’s financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This Update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of the Update is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be effected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which addresses eight specific cash flow issues with the objective of reducing diversity in practice. Among these include recognizing cash payments for debt prepayment or debt extinguishment as cash outflows for financing activities; cash proceeds received from the settlement of insurance claims should be classified on the basis of the related insurance coverage; and cash proceeds received from the settlement of bank-owned life insurance policies should be classified as cash inflows from investing activities while the cash payments for premiums on bank-owned policies may be classified as cash outflows for investing activities, operating activities, or a combination of investing and operating activities. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s statement of cash flows.

The Company had no unvested stock options outstanding or unrecognized stock-based compensation costs outstanding as of September 30, 2016 and 2015.

The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share is calculated by dividing net income by the average shares outstanding. Diluted earnings per share adds the dilutive effects of stock options to average shares outstanding.

The following table sets forth the composition of the weighted-average common shares (denominator) used in the basic and diluted earnings per share computation.

Options to purchase 31,949 shares of common stock, at prices ranging from $17.55 to $40.24, were outstanding during the three and nine months ended September 30, 2016. Of those options, 24,700 were considered dilutive for the three and nine month periods based on the market price exceeding the strike price.

Options to purchase 42,437 shares of common stock, at prices ranging from $17.55 to $37.48, were outstanding during the three and nine months ended September 30, 2015. Of those options, 27,000 were considered dilutive for the three-month period based on the market price exceeding the strike price. For the nine months ended September 30, 2015, 27,250 options were considered dilutive.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP established a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following levels:

The following tables present the assets measured on a recurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The Company obtains fair values from an independent pricing service which represent either quoted market prices for the identical securities (Level I inputs) or fair values determined by pricing models using a market approach that considers observable market data, such as interest rate volatilities, LIBOR yield curve, credit spreads and prices from market makers and live trading systems (Level II).

The following tables present the assets measured on a nonrecurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Impaired loans that are collateral dependent are written down to fair value through the establishment of specific reserves. Techniques used to value the collateral that secure the impaired loan include quoted market prices for identical assets classified as Level I inputs and observable inputs, employed by certified appraisers, for similar assets classified as Level II inputs. In cases where valuation techniques included inputs that are unobservable and are based on estimates and assumptions developed by management based on the best information available under each circumstance, the asset valuation is classified as Level III inputs. The Company values other real estate owned at the estimated fair value of the underlying collateral less expected selling costs. Such values are estimated primarily using appraisals and reflect a market value approach. Due to the significance of the Level III inputs, other real estate owned has been classified as Level III.

The following tables present additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company uses Level III inputs to determine fair value:

(2)	Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range and weighted average of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal.

The estimated fair value of the Company’s financial instruments is as follows:

The Company employed simulation modeling in determining the estimated fair value of financial instruments for which quoted market prices were not available based upon the following assumptions:

Cash and Cash Equivalents, Federal Home Loan Bank Stock, Accrued Interest Receivable, Accrued Interest Payable, and Short-Term Borrowings

The fair value is equal to the cash surrender value of the life insurance policies.

Loans held for sale are carried at lower of cost or fair value. The fair value of loans held for sale is based on secondary market pricing on portfolios with similar characteristics. The changes in fair value of the assets are largely driven by changes in interest rates subsequent to loan funding and changes in the fair value of servicing associated with the mortgage loan held for sale.

The fair values of certificates of deposit and other borrowings are based on the discounted value of contractual cash flows. The discount rates are estimated using rates currently offered for similar instruments with similar remaining maturities. Demand, savings, and money market deposits are valued at the amount payable on demand as of period end.

credit, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, are not considered material for disclosure.

The following tables present the changes in accumulated other comprehensive income by component net of tax for the three and nine months ended September 30, 2016 and 2015, respectively:

The following tables present significant amounts reclassified out of each component of accumulated other comprehensive income for the three and nine months ended September 30, 2016 and 2015, respectively:

The amortized cost and fair values of securities available for sale are as follows:


	December 31, 2015
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government agency securities	$	21,655	$	245	$	(271	)	$	21,629
Obligations of states and political subdivisions:
Taxable		1,989		134		—			2,123
Tax-exempt		91,940		3,402		(175	)		95,167
Mortgage-backed securities in government-sponsored entities		24,480		316		(272	)		24,524
Private-label mortgage-backed securities		2,079		184		—			2,263

Total debt securities		142,143		4,281		(718	)		145,706
Equity securities in financial institutions		750		64		—			814

Total	$	142,893	$	4,345	$	(718	)	$	146,520

The amortized cost and fair value of debt securities at September 30, 2016, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Proceeds from the sales of securities available for sale and the gross realized gains and losses for the three and nine months ended September 30 are as follows:

Investment securities with an approximate carrying value of $64.7 million and $68.8 million at September 30, 2016 and December 31, 2015, respectively, were pledged to secure deposits and other purposes as required by law.

OTTI losses are recognized in earnings when the Company has the intent to sell the debt security or it is more likely than not that it will be required to sell the debt security before recovery of its amortized cost basis. However, even if the Company does not expect to sell a debt security, it must evaluate expected cash flows to be received and determine if a credit loss has occurred.

An unrealized loss is generally deemed to be other than temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. As a result the credit loss component of an OTTI is recorded as a component of investment securities gains (losses) in the accompanying Consolidated Statement of Income, while the remaining portion of the impairment loss is recognized in other comprehensive income, provided the Company does not intend to sell the underlying debt security and it is “more likely than not” that the Company will not have to sell the debt security prior to recovery.

Debt securities issued by U.S. government agencies, U.S. government-sponsored enterprises, and state and political subdivisions accounted for more than 97% of the total available-for-sale portfolio as of September 30, 2016 and no credit losses are expected, given the explicit and implicit guarantees provided by the U.S. federal government and the lack of prolonged unrealized loss positions within the obligations of state and political

subdivisions security portfolio. The Company considers the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:

For the nine months ended September 30, 2016 and 2015, there were no available-for-sale debt securities with an unrealized loss that suffered OTTI. Management does not believe any individual unrealized loss as of September 30, 2016 or December 31, 2015 represented an other-than-temporary impairment. The unrealized losses on debt securities are primarily the result of interest rate changes. These conditions will not prohibit the Company from receiving its contractual principal and interest payments on these debt securities. The fair value of these debt securities is expected to recover as payments are received on these securities and they approach maturity. Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified.

The Company’s primary business activity is with customers located within its local Northeastern Ohio trade area, eastern Geauga County, and contiguous counties to the north, east, and south. The Company also serves the central Ohio market with offices in Dublin, Sunbury and Westerville, Ohio. Commercial, residential, consumer, and agricultural loans are granted. Although the Company has a diversified loan portfolio, loans outstanding to individuals and businesses are dependent upon the local economic conditions in the Company’s immediate trade area.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances net of the allowance for loan and lease losses. Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the

borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is recorded as income or applied against principal according to management’s judgment as to the collectability of such principal.

The following tables summarize the primary segments of the loan portfolio and allowance for loan and lease losses (in thousands):

Installment Loans. The C&I loan segment consists of loans made for the purpose of financing the activities of commercial customers. The residential mortgage loan segment consists of loans made for the purpose of financing the activities of residential homeowners. The commercial mortgage loan segment consists of loans made for the purpose of financing the activities of commercial real estate owners and operators. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. The decrease in the allowance for loan loss for C&I and Residential real estate loan portfolios were offset by increases in the allowance for the CRE loan portfolio.

Management evaluates individual loans in all of the commercial segments for possible impairment based on guidance established by the Board of Directors. Loans are considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in evaluating impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company does not separately evaluate individual consumer and residential mortgage loans for impairment, unless such loans are part of a larger relationship that is impaired.

Once the determination has been made that a loan is impaired, the determination of whether a specific allocation of the allowance is necessary is measured by comparing the recorded investment in the loan to the fair value of the loan using one of the following methods: (a) the present value of expected future cash flows discounted at the loan’s effective interest rate; (b) the loan’s observable market price; or (c) the fair value of the collateral less selling costs. The method is selected on a loan-by-loan basis, with management primarily utilizing the fair value of collateral method. The evaluation of the need and amount of a specific allocation of the allowance and whether a loan can be removed from impairment status is made on a quarterly basis. The Company’s policy for recognizing interest income on impaired loans does not differ from its overall policy for interest recognition.

The following tables present impaired loans by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary (in thousands):

The following tables present interest income by class, recognized on impaired loans (in thousands):

Management uses a nine-point internal risk-rating system to monitor the credit quality of the overall loan portfolio. The first five categories are considered not criticized and are aggregated as Pass rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a Substandard classification. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans greater than 90 days past due are considered Substandard. Any portion of a loan that has been charged off is placed in the Loss category.

To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan-rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death, occurs to raise awareness of a possible credit event. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis with the Chief Credit Officer ultimately responsible for accurate and timely risk ratings. The Credit Department performs an annual review of all commercial relationships with loan balances of $1,000,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Company engages an external consultant to conduct loan reviews on a semiannual basis. Generally, the external consultant reviews commercial relationships greater than $250,000 and/or criticized relationships greater than $125,000. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.

The primary risk of commercial and industrial loans is the current economic uncertainties. C&I loans are, by nature, secured by less substantial collateral than real estate-secured loans. The primary risk of real estate construction loans is potential delays and /or disputes during the completion process. The primary risk of residential real estate loans is current economic uncertainties along with the slow recovery in the housing market. The primary risk of commercial real estate loans is loss of income of the owner or occupier of the property and the inability of the market to sustain rent levels. Consumer installment loans historically have experienced higher delinquency rates. Consumer installments are typically secured by less substantial collateral than other types of credits.

The following tables present the classes of the loan portfolio summarized by the aggregate Pass and the criticized categories of Special Mention, Substandard and Doubtful within the internal risk-rating system (in thousands):

Management further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by the length of time a recorded payment is past due.

Nonperforming assets include nonaccrual loans, troubled debt restructurings (TDRs), loans 90 days or more past due, EMORECO assets, other real estate owned, and repossessed assets. A loan is classified as nonaccrual when, in the opinion of management, there are serious doubts about collectability of interest and principal. Accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of principal and interest is doubtful. Payments received on nonaccrual loans are applied against the principal balance.

The following tables present the classes of the loan portfolio summarized by the aging categories of performing loans (in thousands):

The following tables present the classes of the loan portfolio summarized by nonaccrual loans (in thousands):

The Company’s methodology for determining the ALLL is based on the requirements of ASC Section 310-10-35 for loans individually evaluated for impairment (discussed above) and ASC Subtopic 450-20 for loans collectively evaluated for impairment, as well as the Interagency Policy Statements on the Allowance for Loan and Lease Losses and other bank regulatory guidance. The total of the two components represents the Company’s ALLL. Management also performs impairment analyses on TDRs, which may result in specific reserves.

Loans that are collectively evaluated for impairment are analyzed with general allowances being made as appropriate. For general allowances, historical loss trends are used in the estimation of losses in the current portfolio. These historical loss amounts are modified by other qualitative factors.

Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience. The additional factors that are evaluated quarterly and updated using information ~~specifically states~~obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and nonaccrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry and/or geographic standpoint.

OREO comprises foreclosed assets acquired in settlement of loans and is carried at fair value less estimated cost to sell and is included in other assets on the Consolidated Balance Sheet. At September 30, 2016 and December 31, 2015, there was $1.2 million and $1.4 million of OREO, respectively. As of September 30, 2016, there were no formal foreclosures proceedings.

On July 28, 2016 Middlefield Banc Corp. and Liberty Bank, N.A. entered into an Agreement and Plan of Reorganization. Under the agreement Liberty Bank, N.A. will merge into The Middlefield Banking Company. Of the total merger consideration payable to shareholders of Liberty Bank, N.A., the merger agreement provides that ~~another date applies.~~45% will consist of Middlefield Banc Corp. common stock and the remainder will be cash, for cash of approximately $37.96 per share or Middlefield Banc Corp. common stock at a fixed ratio of 1.1934 for each share of Liberty Bank, N.A. stock exchanged for Middlefield Banc Corp. stock. Liberty Bank, N.A.’s outstanding equity-based awards will be surrendered for total cash currently estimated at approximately $1.147 million. The merger agreement also provides that Liberty Bank, N.A. will pay to its shareholders before merger closing a special dividend in an amount of approximately $3.0 million, subject to possible upward adjustment.

The accounting principles followed by Liberty Bank, N.A. and its subsidiaries (the “Bank”), and the methods of applying these principles, conform with accounting principles generally accepted in the United States of America (“GAAP”) and with prevailing practices within the financial services industry.

A summary of significant accounting and reporting policies applied in the presentation of the accompanying consolidated financial statements follows:

The Bank operates under a national charter and provides full banking services. The Bank is subject to regulation by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation (“FDIC”). The Bank has branches in Beachwood, Solon, and Twinsburg, Ohio; the Bank’s administrative office is located in Beachwood, Ohio.

The Bank has two operating subsidiaries. LBNA Financial LLC was formed in 2010 to reduce premiums paid on title insurance. LBNA Insurance LLC was formed in 2014 to reduce premiums paid on the Bank’s corporate insurance coverage. All intercompany accounts have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Securities are classified as trading, held to maturity, or available for sale upon their acquisition. Securities classified as trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value with unrealized gains and losses recorded in current earnings. Securities held to maturity are securities that the Bank has the positive intent and the ability to hold to maturity; these securities are reported at amortized cost and adjusted for unamortized premiums and discounts. All other securities are classified as available for sale. Securities classified as available for sale are reported at fair value with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. Management determines the appropriate classification at the time of purchase. All investments have been classified as available for sale.

Gains and losses on the sale of investment securities are computed on a specific identification basis. Purchases and sales are accounted for on the trade-date or settlement-date, depending on the settlement terms.

A decline in the fair value of any available for sale security below cost that is deemed to be other than temporary results in a reduction in the carrying amount to fair value. The impairment loss is bifurcated between that related to credit loss which is recognized in noninterest income and that related to all other factors which is recognized in other comprehensive income. To determine whether an impairment is other than temporary, the Bank considers, among other things, the duration and extent to which the fair value of an investment is less than its cost, changes in value subsequent to year end, forecasted performance of the issuer, and whether the Bank has the ability and intent to hold the investment until market price recovery.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for partial charge-offs, the allowance for loan losses, and net deferred origination fees.

Loans intended for sale are carried at the lower of cost or estimated market value determined on an aggregate basis. Net unrealized losses are recognized through a valuation allowance by a charge to income. Gains and losses on the sale of loans are determined under the specific identification method. Refer to Note 3 for disclosure related to loan balances sold during 2016 and 2015.

Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is applied against principal.

For further discussion on nonaccrual loans, impairment, and troubled debt restructurings, see Note 3.

The allowance for loan losses is management’s estimate of loan losses inherent in the loan portfolio at the consolidated statement of financial position date. The allowance for loan losses is assessed on a quarterly basis and provisions for loan losses are made in order to maintain the allowance at a level sufficient to absorb credit losses in the portfolio. Impairment evaluations are performed on loans segregated into homogeneous pools based on similarities in credit profile, product, and property types. Through the evaluation, general allowances for loan losses are assessed based on historical loan loss experience for each homogeneous pool. General allowances are adjusted to address other factors that affect estimated probable losses including the growth of the portfolio; current delinquency statistics; the credit risk grading; national, regional, and local economic factors and trends; and the relative level of individually allocated valuation allowances to the balances of loans individually reviewed. The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). Management believes the allowance is adequate.

Loan fees and certain direct loan origination costs are deferred and recognized as an adjustment to interest income using the level-yield method over the contractual lives of related loans, if the loans are held for investment. When loans are paid off, the unamortized deferred loan fees or costs are immediately included in interest income. If the loans are held for sale, net deferred fees (costs) are not amortized, but rather recognized when the related loans are sold.

carried at the lower of cost or fair value less estimated costs to sell. Management performs periodic evaluations, and a charge to income is recorded for any excess of the carrying value over the fair value less estimated costs to sell the property. Costs relating to holding and maintaining the property are charged to expense. The Bank held real estate which was being carried at $-0- at ~~June~~September 30, 2016 and December 31, 2015, respectively. Sale of real estate owned resulted in a gain of $97,360 in 2015.

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Estimated lives are seven to twenty years for buildings and improvements and three to ten years for furniture, fixtures, and equipment. Costs of maintenance and repairs are charged to expense. Costs of renewals and betterments, where significant in amount, are capitalized.

Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the recovery amount or estimated fair value of the assets. No events or changes in circumstances have occurred causing management to evaluate the recoverability of the Bank’s long-lived assets.

Financial instruments which potentially subject the Bank to concentrations of credit risk consist primarily of temporary cash investments. These cash deposits due from banks may exceed federally insured limits.

The Bank has a Contributory Defined Contribution (“401k”) pension plan covering substantially all employees. The Bank made discretionary contributions of $-0- and $-0- to the Plan for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively.

Compensation expense for awards of equity instruments is recognized on a straight-line basis over the requisite service period based on the grant date fair value estimated in accordance with the provisions of FASB ASC 718,Compensation – Stock Compensation. Share-based compensation expense is included in salaries and employee benefits in the consolidated statements of comprehensive income.

The grant date fair value of stock options is estimated using the Black-Scholes option-pricing model using assumptions for the expected option term, expected stock price volatility, risk-free interest rate, and expected dividend yield. Due to limited historical data on exercise of share options, the simplified method is used to estimate expected option term.

The Bank owns insurance on the lives of a certain group of ex-employees who at one time were key employees of the Bank. The policies were purchased in 2002 and 2003 to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset in the consolidated statements of financial condition and any increases in the cash surrender value are recorded as noninterest income in the consolidated statements of comprehensive income. In the event of the death of an insured individual under these policies, the Bank would receive a death benefit, which would be recorded as noninterest income.

Basic earnings per share is computed by dividing net income (loss) by the weighted average shares of common stock outstanding. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution, if any, of unexercised stock options that could occur if stock options were exercised and converted into common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Bank recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Bank believes that it has appropriate support for any tax positions taken and, as such, does not have any uncertain tax positions that are material to the consolidated financial statements.

The Bank has defined cash equivalents as those amounts due from depository institutions and federal funds sold.

The Bank paid interest on deposits and FHLB advances of ~~$431,879~~$638,265 and ~~$494,091~~$731,038 in the ~~six~~nine month periods ending 2016 and 2015, respectively.

The Bank had income tax payments of $41,800 and $1,039,801 in the ~~six~~nine month periods ended 2016 and 2015, respectively.

Management has evaluated the events and transactions through ~~September 30,~~November 11, 2016, which is the date the consolidated financial statements were available to be issued, for potential recognition or disclosure herein. There were none noted.

The amortized cost and estimated fair values of securities available for sale are as follows:

There were no sales from the investment securities available for sale portfolio during the ~~six~~nine month periods ended ~~June~~September 30, 2016 and 2015.

The unrealized losses on investment securities were attributable to market rate increases. The contractual terms of these investments do not permit the issuer to settle the security at a price less than the par value of the investment.

The Bank performs a periodic assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment pursuant to FASB ASC Topic 320,Investments – Debt and Equity Securities. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The accounting literature requires the Bank to assess whether the unrealized loss is other-than-temporary. Since the decline in value is attributable to changes in interest rates and not credit quality and because the Bank has both the intent and ability to hold such securities for a time necessary to recover the amortized cost, these investments are not considered other-than-temporarily impaired.

The amortized cost and estimated fair values of investment securities available for sale at ~~June~~September 30, 2016 and December 31 2015, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because certain securities contain provisions which permit the issuer to repay, at par, the obligation prior to the stated maturity.

No securities available for sale at ~~June~~September 30, 2016 and 2015 were pledged to secure deposits, borrowings and other purposes as required by law.

The Bank grants consumer, commercial, and residential loans to customers throughout its market area, which is concentrated in Cuyahoga and Summit counties of Ohio. Although the Bank has a diversified loan portfolio at September 30, 2016 and December 31, 2015, ~~and 2014,~~ a substantial portion of its debtors’ ability to honor their loan agreements is dependent upon the economic stability of its immediate trade area.

Sale of education loans resulted in gains of ~~$190,278~~$287,580 and ~~$67,716~~$186,587 in the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. Sale of Small Business Administration loans resulted in gains of ~~$-0-~~$155,990 and ~~$71,442~~$67,192 in the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. Sale of residential real estate mortgage loans resulted in gains of ~~$48,379~~$86,232 and ~~$58,175~~$76,000 in the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively.

A loan is considered impaired when it is probable that not all principal and interest amounts will be collected according to the loan contract. Residential mortgage, education less than 90 days past due, and consumer loans are evaluated collectively for impairment. Individual commercial and commercial real estate loans are evaluated for impairment. Impaired loans are written down by the establishment of a specific allowance where necessary. The Bank estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan losses is maintained for estimated losses. If a loan is impaired, a portion of the allowance is allocated to that loan, equal to the excess of the loan’s carrying value over the fair value of the collateral or the excess of the loan’s carrying value over the present value of expected future cash flows. The Bank charges off principal at the earlier of (i) when a total loss of principal has been deemed to have occurred as a result of the book value exceeding the fair value or net realizable value or (ii) when collection efforts have ceased.

impairment individually to determine the probable loss content and are assigned a specific loan allowance if deemed appropriate. Loan modifications are handled on a case by case basis and are negotiated to achieve mutually agreeable terms that maximize loan collectability and meet the client’s financial needs. After one year, a loan is no longer included in the balance of impaired loans if the loan was modified to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement. No troubled debt restructurings were reclassified out of impaired loans during the six months ended June 30, 2016 and 2015. At ~~June~~September 30, 2016, one residential real estate loan totaling ~~$913,065~~$906,224 was classified as a TDR. At December 31, 2015, one residential real estate loan totaling $926,975 was classified as a TDR.

The Bank manages its exposure to credit risk by closely monitoring loan performance trends and general economic conditions. A key indicator of the potential for future credit losses is the level of nonaccrual loans.

Nonaccrual loan balances as of ~~June~~September 30, 2016 and December 31, 2015 are as follows:

At ~~June~~September 30, 2016, approximately ~~$184.8~~$195.3 million, or ~~98.5%~~98.7%, of the Bank’s total loans is current. Information regarding delinquent loans as of ~~June~~September 30, 2016 and December 31, 2015 is as follows:

Sound credit systems, practices, and procedures such as credit risk grading systems; effective credit review and examination processes; effective loan monitoring, problem identification, and resolution processes; and a conservative loss recognition process and charge-off policy are integral to management’s proper assessment of the adequacy of the allowance. Many factors are considered when grades are assigned to individual loans and portfolio segments such as current and past delinquency, financial statements of the borrower, current net realizable value of collateral, and the general economic environment and specific economic trends affecting the loan portfolio.

The allowance for loan losses represents the amount which management estimates is adequate to provide for probable loan losses inherent in its loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan losses, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. While management uses the best information available to make these evaluations, future adjustments to the allowance may be necessary if economic conditions change substantially from the assumptions used in making the evaluations. Future adjustments to the allowance may also be required by regulatory examiners based on their judgments about information available to them at the time of their examination. Management believes the allowance is adequate.

Activity in the allowance for loan losses by segment for ~~June~~September 30, 2016 and December 31, 2015 is summarized as follows:

Major classifications of premises and equipment as of ~~June~~September 30, 2016 and December 31, 2015 are summarized as follows:

Depreciation charged to operations was ~~$51,200~~$78,412 and ~~$76,064~~$113,721 in the ~~six~~nine month periods ended 2016 and 2015, respectively, which is included in occupancy and furniture and equipment expense in the consolidated statements of comprehensive income.

The Federal Reserve Bank (“FRB”) and Federal Home Loan Bank (“FHLB”) stocks are restricted investments because they may only be sold back to the FRB and FHLB, respectively. These investments are carried at par value.

Time deposits include certificates of deposit in denominations of $100,000 or more that aggregated ~~$21,210,656~~$18,697,098 and $24,400,951 at ~~June~~September 30, 2016 and December 31, 2015, respectively. Such deposits represented approximately ~~53%~~52% and 53% of the Bank’s total time deposits as of ~~June~~September 30, 2016 and December 31, 2015, respectively.

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act was signed into law, which, in part, permanently increased the maximum amount of deposit insurance to $250,000 per depositor, retroactive to January 1, 2009.

Certificates of deposit in denominations of $250,000 or more aggregated ~~$4,885,891~~$4,320,515 and $5,694,618 at ~~June~~September 30, 2016 and December 31, 2015, respectively. Such deposits represented approximately 12% and 12%, respectively, of the Bank’s total time deposits.

The Bank does not have any brokered deposits. The Bank has pledged cash in the amount of $4.5 million and $4.5 million at ~~June~~September 30, 2016 and December 31, 2015, respectively, against public fund deposits.

At ~~June~~September 30, 2016, scheduled maturities of certificates of deposit are as follows:

The Bank had no advances from the FHLB at ~~June~~September 30, 2016 and December 31, 2015.

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the OCC that, if undertaken, could have a direct material effect on the consolidated financial statements of the Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in table below) of common equity Tier 1, Tier 1, and Total capital (as defined in the regulations) to risk-weighted assets (as defined) and Tier 1 capital (as defined) to average assets (as defined). The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet assets to broad risk categories.

Federal bank regulators apply certain ratios to assign FDIC-insured depository institutions to one of five categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” At ~~June~~September 30, 2016 and December 31, 2015, the Bank exceeded all regulatory capital requirements and is considered “well capitalized” under regulatory guidelines.

Events beyond management’s control, such as fluctuations in interest rates or a downturn in the economy in areas in which the Bank’s loans and securities are concentrated, could adversely affect future earnings and, consequently, the Bank’s ability to meet its future capital requirements.

The actual regulatory capital ratios calculated for the Bank, along with the capital amounts and ratios to meet the minimum capital adequacy requirements and the amounts required to qualify as “well capitalized” under the Federal Deposit Insurance Act, are as follows:

In the normal course of business, loans are extended and deposit relationships incurred with directors, executive officers, and their associates. In management’s opinion, all of these transactions are on substantially the same terms and conditions as those with other individuals and businesses of comparable creditworthiness and deposit activity.

A summary of loan activity for these related parties, as defined, for the ~~six~~nine month periods ended ~~June~~September 30, 2016 and 2015 is as follows:

Deposits of related parties amounted to approximately ~~$28.3~~$26.6 million or ~~14.88%~~14.13% and $15.9 million or 8.8% of the Bank’s total deposits as of ~~June~~September 30, 2016 and December 31, 2015, respectively.

In the normal course of business, the Bank enters into commitments with off-balance-sheet risk to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments totaled ~~$36.9~~$31.7 and $25.9 million at ~~June~~September 30, 2016 and December 31, 2015, respectively.

Commitments to extend credit involve elements of credit risk and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the commitment is represented by the contractual amount of the commitment. The Bank generally uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Interest rate risk on commitments to extend credit results from the possibility that interest rates may have moved unfavorably from the position of the Bank since the time the commitment was made. These commitments are comprised primarily of available commercial and personal lines of credit and unfunded loans which have been authorized for disbursement.

The Company leases its administrative office, certain of its branches, and certain equipment under renewable operating lease agreements. Future minimum payments under noncancelable operating leases with initial or remaining terms of one year or more consisted of the following at ~~June~~September 30, 2016:

Lease payments charged to operations for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 were ~~$158,535~~$239,431 and ~~$172,908,~~$191,461, respectively.

The Bank is involved in litigation and is subject to certain claims that arise in the normal course of operations. In the opinion of management, the ultimate disposition of the litigation and claims will not have a material adverse effect on the Bank’s operations or financial position.

During 2016 and 2015, the Board approved the issuance of 1,677 and 2,868 shares totaling $52,976 and $86,585, respectively, as incentive compensation to four executive officers and one senior officer of the Bank. During 2016, one (1) executive officer exercised 990 outstanding stock options totaling $29,700. Also during 2015, two (2) employees exercised 8,011 outstanding stock options totaling $211,890.

At ~~June~~September 30, 2016, the Bank had three stock option plans under which shares of common stock are reserved for grant to officers and employees. All of the Bank’s plans have been approved by the Bank’s stockholders. The Bank believes that such awards better align the interests of its employees with those of its stockholders.

Option awards are granted with an exercise price at the fair market value of the Bank’s stock at the date of grant and generally vest over three years. The date on which the options are first exercisable is determined by a committee of the Board of Directors. The options expire no later than ten years from the grant date.

GAAP requires that stock options be recognized as compensation expense based on their fair value over the vesting period. The Bank recognized stock option compensation expense of $1,337 and ~~$3,360~~$5,040 in the ~~six~~nine months ended in 2016 and 2015, respectively. The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model using the assumptions noted in the following table. Expected volatilities are based upon implied volatilities from traded options on stock, historical volatility, and other factors that affect the Bank and similar financial institutions. The Bank uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that the options granted are expected to be outstanding. The risk free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. There were no options granted in 2016 or 2015.

The total fair value of shares vested during the year ended December 31, 2015 was approximately $15,676. There were no options granted during the year 2015. The total intrinsic value of options exercised during the year ended December 31, 2015 was $90,504. The Bank has 98,000 shares remaining available for grant under the stock option plans.

As of ~~June~~September 30, 2016, there was $-0- unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. ~~That cost is expected to be recognized over a weighted-average period of five years.~~

At ~~June~~September 30, 2016, the Bank has $3.0 million available under the terms of a federal funds line of credit, which is used for daily or short-term cash needs. No amounts have been drawn on the line during the ~~six~~nine month periods ended in 2016 and 2015.

The carrying values of cash and due from banks, federal funds sold, accrued interest and other assets, and accrued interest and other liabilities are reasonable estimates of fair value due to the short-term nature of these financial instruments.

The Bank estimates the fair value of financial instruments using available market information and other generally accepted valuation methodologies. Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The three levels of inputs are defined as follows:

Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets.

Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with few transactions, or model-based valuation techniques using assumptions that are observable in the market.

The asset’s fair value measurement level is based on the lowest level of any input that is significant to the fair value measurement.

Level 1 securities are investments in U.S. agency securities in other banks. Level 2 investments are certificates of deposit.

The following table presents estimated fair value of the Bank’s financial instruments. The estimated fair value amounts have been determined by the Bank using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Bank could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Cash, deposits with banks, and federal funds sold– The carrying amount is a reasonable estimate of fair value.

Securities available for sale– Estimated fair value for investments and mortgage-backed securities is based on quoted market prices, dealer quotes, and prices obtained from independent pricing services at the consolidated statement of financial condition date.

Loans– Fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Accrued interest and other assets– The carrying amount is a reasonable estimate of fair value.

Cash value of life insurance– The carrying amount is a reasonable estimate of fair value.

Investments in FRB and FHLB– The fair value is estimated to be the carrying value which is par. All transactions in the capital stock of the FRB and the FHLB are executed at par.

Deposits– The fair value of demand deposits, savings accounts, and money market deposit accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificate of deposit is estimated by discounting the future cash flows and rates currently offered for deposits of similar remaining maturities.

Accrued interest and other liabilities– The carrying amount is a reasonable estimate of fair value.

We have audited the accompanying consolidated financial statements of Liberty Bank, N.A. and its subsidiaries, which comprise the consolidated statements of financial condition as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, changes in stockholders’ equity, and cash flows for the three years in the period ended December 31, 2015, and the related notes to the financial statements.

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Liberty Bank, N.A. and its subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for the three years in the period ended December 31, 2015 in accordance with accounting principles generally accepted in the United States of America.

A summary of significant accounting and reporting policies applied in the presentation of the accompanying consolidated financial statements follows:

Securities are classified as trading, held to maturity, or available for sale upon their acquisition. Securities classified as trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value with unrealized gains and losses recorded in current earnings. Securities held to maturity are securities that the Bank has the positive intent and the ability to hold to maturity; these securities are reported at amortized cost and adjusted for unamortized premiums and discounts. All other securities are classified as available for sale. Securities classified as available for sale are reported at fair value with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. Management determines the appropriate classification at the time of purchase. All investments have been classified as available for sale.

For further discussion on nonaccrual loans, impairment, and troubled debt restructurings, see Note 3.

Real estate owned represents real estate acquired through foreclosure or deed in lieu of foreclosure and is initially recorded at fair value less estimated costs to sell. Subsequent to acquisition, real estate owned is carried at the lower of cost or fair value less estimated costs to sell. Management performs periodic evaluations, and a charge to income is recorded for any excess of the carrying value over the fair value less estimated costs to sell the property.

The Bank grants consumer, commercial, and residential loans to customers throughout its market area, which is concentrated in Cuyahoga and Summit counties of Ohio.

A loan modification in which the borrower is experiencing financial difficulties and is granted a concession without commensurate financial, structural, or legal consideration is classified as a troubled debt restructuring (“TDR”). All commercial and consumer loan TDRs, regardless of size, are evaluated for impairment individually to determine the probable loss content and are assigned a specific loan allowance if deemed appropriate. Loan modifications are handled on a case by case basis and are negotiated to achieve mutually agreeable terms that maximize loan collectability and meet the client’s financial needs. After one year, a loan is no longer included in the balance of impaired loans if the loan was modified to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement. No troubled debt restructurings were reclassified out of impaired loans during the years ended December 31, 2015, 2014 and 2013. At December 31, 2015, one residential real estate loan totaling $926,975 was classified as a TDR. At December 31, 2014, one commercial real estate loan totaling $119,629 was classified as a TDR.

Time deposits include certificates of deposit in denominations of $100,000 or more that aggregated $24,400,951 and $23,970,498 at December 31, 2015 and 2014, respectively. Such deposits represented approximately 53% and 51% of the Bank’s total time deposits as of December 31, 2015 and 2014, respectively.

Federal bank regulators apply certain ratios to assign FDIC-insured depository institutions to one of five categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” At December 31, 2015, the Bank exceeded all regulatory capital requirements and is considered “well capitalized” under regulatory guidelines.

A summary of loan activity for these related parties, as defined, for the years ended December 31, 2015 and 2014 is as follows:

Deposits of related parties amounted to approximately $15.9 million or 8.8% and $17.2 million or 9.6% of the Bank’s total deposits as of December 31, 2015 and 2014, respectively.

In the normal course of business, the Bank enters into commitments with off-balance-sheet risk to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments totaled $25.9 and $22.2 million at December 31, 2015 and 2014, respectively.

Lease payments charged to operations for the years ended December 31, 2015, 2014 and 2013 were $272,298, $355,961 and $344,388, respectively.

During 2013, the Board approved the issuance of 2,582 shares totaling $70,566 as incentive compensation to four executive officers and one senior officer of the Bank.

At December 31, 2015, the Bank had three stock option plans under which shares of common stock are reserved for grant to officers and employees. All of the Bank’s plans have been approved by the Bank’s stockholders. The Bank believes that such awards better align the interests of its employees with those of its stockholders.

GAAP requires that stock options be recognized as compensation expense based on their fair value over the vesting period. The Bank recognized stock option compensation expense of $6,720, $15,473 and $24,800 in 2015, 2014 and 2013, respectively. The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model using the assumptions noted in the following table. Expected volatilities are based upon implied volatilities from traded options on stock, historical volatility, and other factors that affect the Bank and similar financial institutions. The Bank uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that the options granted are expected to be outstanding. The risk free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. There were no options granted in 2015 or 2014.

The following is an analysis of the stock option activity for each of the years 2015, 2014 and 2013 and the stock options outstanding at the end of the respective periods:

As of December 31, 2015, there was approximately $1,336 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of five years. A summary of the status of the Bank’s non-vested shares as of December 31, 2015, and changes during the year then ended, is as follows:

At December 31, 2015, the Bank has $3.0 million available under the terms of a federal funds line of credit, which is used for daily or short-term cash needs. No amounts have been drawn on the line during 2015 and 2014.

Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets.

The asset’s fair value measurement level is based on the lowest level of any input that is significant to the fair value measurement.

Level 1 securities are investments in U.S. agency securities in other banks. Level 2 investments are certificates of deposit.

Cash, deposits with banks, and federal funds sold – The carrying amount is a reasonable estimate of fair value.

Securities available for sale – Estimated fair value for investments and mortgage-backed securities is based on quoted market prices, dealer quotes, and prices obtained from independent pricing services at the consolidated statement of financial condition date.

Loans – Fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Accrued interest and other assets – The carrying amount is a reasonable estimate of fair value.

Cash value of life insurance – The carrying amount is a reasonable estimate of fair value.

Investments in FRB and FHLB – The fair value is estimated to be the carrying value which is par. All transactions in the capital stock of the FRB and the FHLB are executed at par.

Deposits – The fair value of demand deposits, savings accounts, and money market deposit accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificate of deposit is estimated by discounting the future cash flows and rates currently offered for deposits of similar remaining maturities.

Accrued interest and other liabilities – The carrying amount is a reasonable estimate of fair value.

stated in Article 9 (other than those conditions that by their terms are to be satisfied at the Closing, but subject to satisfaction or waiver of those conditions), or such other date that may be agreed to in writing by Middlefield Banc Corp. and Liberty Bank. The Mergers will be effected by filing of a certificate of merger with the Ohio Secretary of State in accordance with Ohio banking law and section 1701.81 of the Ohio General Corporation Law on the day of Closing (the “Closing Date”). The Mergers will be effective on the date and time specified in the certificate of merger (the “Effective Time”).

2.8Tax Consequences. The parties hereto intend that the Mergers constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986 and that this Agreement constitute a plan of reorganization, as that term is used in Sections 354 and 361 of the Internal Revenue Code of 1986.

The parties hereto agree to appropriately amend this Agreement and any related documents in order to reflect a revised structure.

2.10Absence of Control. It is the intent of the parties hereto that, on account of this Agreement and until the Effective Time, Middlefield Banc Corp. and The Middlefield Banking Company not be considered to control Liberty Bank directly or indirectly or to exercise directly or indirectly a controlling influence over the management or policies of Liberty Bank.

3.1Conversion of Liberty Bank Common Stock; Consideration Payable in Interim Merger; Possible Adjustment in Merger Consideration. Without any action on the part of Middlefield Banc Corp., The Middlefield Banking Company, Liberty Bank, or the holders of any of the shares of Liberty Bank common stock, at the Effective Time the Interim Merger will be effected on the following terms:

3.1.1 Each share of Middlefield Banc Corp. common stock and each share of The Middlefield Banking Company common stock issued and outstanding immediately before the Effective Time will remain issued and outstanding at the Effective Time, unchanged by the Mergers.

3.1.2 All shares of Liberty Bank common stock held in the treasury of Liberty Bank and each share of Liberty Bank common stock owned by Middlefield Banc Corp. (other than shares held in a fiduciary capacity or in connection with debts previously contracted) (the “Treasury Stock”) will at the Effective Time cease to exist. The shares of Treasury Stock, including Certificates therefor, will be canceled and no payment or distribution will be made in consideration therefor.

3.1.3 Except for Treasury Stock and Dissenting Shares and as provided in and subject to the limitations in this Agreement, by virtue of the Interim Merger, each share of Liberty Bank common stock issued and

outstanding immediately before the Effective Time will at the Effective Time become and be converted into the right to receive at the election of the holder as provided in Section 3.2 either (i) $37.96 in cash (the “Cash Consideration”), or (ii) 1.1934 shares (the “Exchange Ratio”) of Middlefield Banc Corp. common stock (the “Stock Consideration”). Together, the Cash Consideration and the Stock Consideration are sometimes referred to as the “Merger Consideration.” All of the 100 outstanding shares of common stock of MBC Interim Bank, no par value, shall be cancelled for no additional consideration in connection with the Interim Merger. It is understood and agreed that the Merger Consideration is subject to adjustment in the event that the special dividend payable to the Liberty Bank stockholders pursuant to Section 6.1(b) of this Agreement exceeds the sum of (i) $3,000,000 and (ii) such additional incremental amount necessary to ensure that the per share value is the same for all Liberty Bank stockholders entitled to receive it (collectively, the “Base Special Dividend”). If it is determined, upon completion of the review process outlined in Section 6.1(b) hereof and receipt of regulatory approval, that Liberty Bank will pay an amount to Liberty Bank stockholders in excess of the Base Special Dividend (the “Excess Amount”), then the Merger Consideration will be reduced by the Excess Amount, adjusted as necessary to ensure that all Liberty Bank stockholders entitled thereto receive the same per share value. Any adjustment in Merger Consideration shall be in the same form and subject to the same allocations between Middlefield Banc Corp. common stock and cash and election procedures as are specified in this Article 3.

3.1.4 Except as stated in Section 3.1.2 or Section 3.1.5, at the Effective Time outstanding shares of Liberty Bank common stock will no longer be outstanding, will be automatically canceled, will cease to exist, and will thereafter represent solely the right to receive the Merger Consideration and any dividends or distributions with a record date before the Effective Time that were declared or made by Liberty Bank on the shares of Liberty Bank common stock in accordance with the terms of this Agreement on or before the Effective Time but that remain unpaid at the Effective Time.

3.1.5 Each outstanding share of Liberty Bank common stock, the holder of which has perfected the right to dissent under the National Bank Act and has not effectively withdrawn or lost dissenters’ rights as of the Effective Time (the “Dissenting Shares”), will not be converted into or represent a right to receive the Merger Consideration in connection with the Interim Merger, and the holder thereof will be entitled solely to rights granted by applicable law. Liberty Bank will give Middlefield Banc Corp. immediate notice upon receipt by Liberty Bank of any demand for payment of the fair value of shares of Liberty Bank common stock and of withdrawals of demand for payment and any other related communications (any stockholder duly making a demand being hereinafter called a “Dissenting Stockholder”). Middlefield Banc Corp. may participate in all discussions, negotiations, and proceedings relating to a demand for payment of the fair value of shares of Liberty Bank common stock. Except with advance written consent of Middlefield Banc Corp., Liberty Bank will not voluntarily make any payment on, settle or offer to settle a demand for payment, or waive a failure of timely delivery of a written demand for appraisal or of the taking of any other action by the Dissenting Stockholder as may be necessary to perfect appraisal rights under applicable law. Any payments made for Dissenting Shares will be made by the Surviving Institution.

3.1.6 If at or before the Effective Time of the Interim Merger, whether through failure to perfect or otherwise, a Dissenting Stockholder withdraws or loses the right to payment, the holder’s shares of Liberty Bank common stock will be converted into the right to receive Merger Consideration in accordance with the applicable provisions of this Agreement. If after the Effective Time of the Interim Merger, whether through failure to perfect or otherwise, a Dissenting Stockholder withdraws or loses the right to payment, each share of Liberty Bank common stock of the holder is entitled to receive the Merger Consideration.

3.1.7 Regardless of anything to the contrary in this Agreement, no certificates or scrip for fractional shares of Middlefield Banc Corp. will be issued upon the surrender of Certificates for exchange, no dividend or distribution on Middlefield Banc Corp. common stock will be payable on or for fractional share interests, and fractional share interests will not entitle the owner thereof to vote or to any other shareholder rights. In lieu of issuance of fractional shares, to each former holder of Liberty Bank common stock who otherwise would be

entitled to receive a fractional share of Middlefield Banc Corp. common stock, Middlefield Banc Corp. will pay an amount in cash equal to the product of (x) the fraction of a share to which the holder would otherwise have been entitled and (y) the volume-weighted average closing price of a share of Middlefield Banc Corp. common stock for the 30 trading days immediately before the Closing Date, rounded to the nearest cent and without interest. For purposes of determining a fractional share interest, all shares of Liberty Bank common stock owned by a Liberty Bank stockholder will be combined for calculation of the maximum number of whole shares of Middlefield Banc Corp. common stock issuable to the Liberty Bank stockholder.

3.1.8 If Middlefield Banc Corp. changes, or if the Middlefield Banc Corp. Board sets a record date that will occur before the Effective Time for a change in, the number or kind of shares of Middlefield Banc Corp. common stock outstanding by a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction involving issuance of shares without consideration, the Merger Consideration will be adjusted proportionately to account for the change. If Liberty Bank changes, or if the Liberty Bank Board sets a record date that will occur before the Effective Time for a change in, the number or kind of shares of Liberty Bank common stock (or rights thereto) outstanding by a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction involving issuance of shares without consideration, the Merger Consideration will be adjusted proportionately to account for the change.

3.2.1 In accordance with the following procedures, holders of Liberty Bank common stock may elect to receive Stock Consideration or Cash Consideration (in either case without interest) in exchange for their shares of Liberty Bank common stock; provided, however, that, excluding Treasury Stock and Dissenting Shares, in the aggregate 45% of the total number of shares of Liberty Bank common stock issued and outstanding at the Effective Time are converted into the Stock Consideration (the “Stock Conversion Number”) and the remaining outstanding shares of Liberty Bank common stock are converted into the Cash Consideration. Shares of Liberty Bank common stock for which a Cash Election is made (including a Mixed Election, as defined in Section 3.2.2) are referred to herein as the “Cash Election Shares.” Shares of Liberty Bank common stock for which a Stock Election is made (including a Mixed Election) are referred to as the “Stock Election Shares.” Shares of Liberty Bank common stock for which no election is made or for which an Election Form is not returned properly completed are referred to herein as “Non-Election Shares.” The aggregate number of shares of Liberty Bank common stock for which a Stock Election is made is referred to herein as the “Stock Election Number.”

3.2.2 At least 20 business days before the anticipated Effective Time or on such other date as Middlefield Banc Corp. and Liberty Bank mutually agree (the “Mailing Date”) Middlefield Banc Corp. will mail or cause to be mailed to each holder of record of Liberty Bank common stock as of five business days before the Mailing Date (the “Election Form Record Date”) an election form and other appropriate and customary transmittal materials in such form as the parties shall mutually agree (the “Election Form”), specifying that, except with respect to shares of Liberty Common Stock held in book-entry form, delivery is effected and risk of loss and title to the Certificates passes only upon proper delivery of Certificates to the Exchange Agent. Subject to the allocation and election procedures set forth in this Section 3.2, the Election Form will permit each holder (1) to elect to receive Cash Consideration for all of the holder’s shares of Liberty Bank common stock (a “Cash Election”), (2) to elect to receive Stock Consideration for all of the shares (a “Stock Election”), (3) to receive Stock Consideration for part of the holder’s Liberty Bank common stock and Cash Consideration for the remaining part of the holder’s Liberty Bank common stock (a “Mixed Election”), or (4) to state no preference for receipt of cash or Middlefield Banc Corp. common stock (a “Non-Election”). A holder who holds shares of Liberty Bank common stock as nominee, trustee, or in another representative capacity may submit multiple Election Forms, provided that each Election Form covers all shares of Liberty Bank common stock held by the representative for a particular beneficial owner. Any shares of Liberty Bank common stock for which the holder does not by the Election Deadline make an effective election will be deemed Non-Election Shares.

3.2.3 To be effective, a properly completed Election Form must be submitted to the Exchange Agent on or before 5:00 p.m., New York City time, on the 20th day after the Mailing Date or such other time and date before

the Effective Time as Middlefield Banc Corp. and Liberty Bank mutually agree (the “Election Deadline.” The Election Deadline may not be on or after the Effective Time. Liberty Bank will make available up to two separate Election Forms, or such additional Election Forms as Middlefield Banc Corp. may permit, to all persons who become holders or beneficial owners of Liberty Bank common stock between the Election Form Record Date and the close of business on the business day before the Election Deadline. Liberty Bank will provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein. An election is properly made if and only if the Exchange Agent actually receives a properly completed Election Form by the Election Deadline. If a holder of Liberty Bank common stock either (x) does not submit a properly completed Election Form in a timely fashion or (y) revokes the Election Form before the Election Deadline, the shares of Liberty Bank common stock held by that stockholder will be designated as Non-Election Shares. By written notice to the Exchange Agent, an Election Form may be revoked or changed by the person submitting the Election Form only if the notice of revocation or change is actually received by the Exchange Agent on or before the Election Deadline. Middlefield Banc Corp. will cause the Certificate or Certificates relating to a revoked Election Form to be promptly returned without charge to the person submitting the Election Form to the Exchange Agent. Subject to the terms of this Agreement and the terms of the Election Form, the Exchange Agent is entitled to determine when an election, modification, or revocation is received and whether an election, modification, or revocation is properly made.

3.2.4 If the Stock Election Number exceeds the Stock Conversion Number, all Cash Election Shares and all Non-Election Shares will be converted into the right to receive Cash Consideration, and subject to Section 3.1.7 hereof, each holder of Stock Election Shares will be entitled to receive the Stock Consideration solely for a number of Stock Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Stock Election Shares held by the holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of the holder’s Stock Election Shares being converted into the right to receive Cash Consideration.

3.2.5 If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), all Stock Election Shares will be converted into the right to receive Stock Consideration and the Non-Election Shares and Cash Election Shares will be treated in the following manner:

(A) if the Shortfall Number is less than or equal to the number of Non-Election Shares, all Cash Election Shares will be converted into the right to receive Cash Consideration and, subject to Section 3.1.7 hereof, each holder of Non-Election Shares will receive the Stock Consideration for a number of Non-Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Non-Election Shares held by the holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of the holder’s Non-Election Shares being converted into the right to receive Cash Consideration, or

(B) if the Shortfall Number exceeds the number of Non-Election Shares, all Non- Election Shares will be converted into the right to receive Stock Consideration, and subject to Section 3.1.7 each holder of Cash Election Shares will receive Stock Consideration for a number of Cash Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Cash Election Shares held by the holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of the holder’s Cash Election Shares being converted into the right to receive Cash Consideration.

3.3.1Middlefield Banc Corp. to Make Merger Consideration Available. Before the Effective Time and for exchange in accordance with this Section 3.3, Middlefield Banc Corp. will deposit or cause to be deposited with the Exchange Agent for the benefit of the holders of Liberty Bank common stock and cash in an amount

sufficient to pay the Merger Consideration under this Article 3. Middlefield Banc Corp. will instruct the Exchange Agent to issue the cash and shares of Middlefield Banc Corp. common stock for exchange in accordance with this Section 3.3. Together with dividends or distributions payable but without interest thereon, the cash and shares of Middlefield Banc Corp. common stock deposited as provided herein are referred to as the “Exchange Fund.” The Exchange Fund also includes the cash to be deposited by Middlefield Banc Corp. under Section 3.5 for payment to holders of stock options and phantom shares.

3.3.2Exchange of Certificates. Within five Business Days after the Effective Time Middlefield Banc Corp. will cause the Exchange Agent to mail to each holder of a Certificate or Certificates a form letter of transmittal for return to the Exchange Agent and instructions for surrendering the Certificates. The letter of transmittal will specify that delivery is effected and risk of loss and title to the Certificates pass only upon delivery of the Certificates (or in the case of Liberty Common Stock held in book-entry form, book-entry account statements), to the Exchange Agent. Upon proper surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with a properly completed and duly executed letter of transmittal, the holder of the Certificate is entitled to receive in exchange for the Merger Consideration. No interest will be paid or accrued on any cash payable in lieu of fractional shares or any unpaid dividends and distributions, if any, payable to holders of Certificates.

3.3.3Rights of Certificate Holders after the Effective Time. After the Effective Time, the holder of a Certificate formerly representing issued and outstanding Liberty Bank common stock has no rights except the right to surrender the Certificate in exchange for Merger Consideration as provided in this Agreement. No dividends or other distributions declared after the Effective Time on Middlefield Banc Corp. common stock will be paid to the holder of any unsurrendered Certificate until the holder surrenders the Certificate in accordance with this Section 3.3. After surrender of a Certificate in accordance with this Section 3.3 the record holder is entitled to receive dividends or other distributions, without interest, which had become payable on shares of Middlefield Banc Corp. common stock.

3.3.4Surrender by Persons Other than Record Holders. If the Person surrendering a Certificate and signing the accompanying letter of transmittal is not the record holder, it is a condition of the payment of the Merger Consideration that (x) the Certificate is properly endorsed to that Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on the Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering the Certificate and signing the letter of transmittal to do so on behalf of the record holder, and (y) the Person requesting exchange pays to the Exchange Agent in advance any transfer or other similar taxes required for payment to a Person other than the registered holder of the Certificate surrendered, or required for any other reason, or establishes to the Exchange Agent’s satisfaction that the tax has been paid or is not payable.

3.3.5Closing of Transfer Books. From and after the Effective Time, there may be no transfers on the stock transfer books of Liberty Bank of the Liberty Bank common stock that were outstanding immediately before the Effective Time. If after the Effective Time Certificates representing shares are presented for transfer to the Exchange Agent, they will be exchanged for the Merger Consideration and canceled as provided in this Section 3.3.

3.3.6Return of Exchange Fund. At any time after nine months have elapsed since the Effective Time, Middlefield Banc Corp. is entitled to require the Exchange Agent to deliver to Middlefield Banc Corp. any portion of the Exchange Fund made available to the Exchange Agent but not disbursed to holders of Certificates (including without limitation all interest and other income received by the Exchange Agent on funds made available to it), and thereafter holders are entitled to look solely to Middlefield Banc Corp. for any Merger Consideration that may be payable upon due surrender of Certificates (subject to abandoned property, escheat and other similar laws). However, neither Middlefield Banc Corp. nor the Exchange Agent is liable to any holder of a Certificate for any Merger Consideration delivered in good faith to a public official under abandoned property, escheat, or other similar law.

3.3.7Lost, Stolen, or Destroyed Certificates. If a Person claiming a Certificate to be lost, stolen, or destroyed submits to the Exchange Agent an affidavit that the Certificate is lost, stolen, or destroyed and posts a bond in such amount as the Exchange Agent reasonably directs as indemnity against any claim that may be made against it for the Certificate, the Exchange Agent will issue the Merger Consideration in exchange for the lost, stolen, or destroyed Certificate.

3.3.8Withholding. Middlefield Banc Corp. or the Exchange Agent is entitled to deduct and withhold from the consideration otherwise payable under this Agreement to any holder of Liberty Bank common stock such amounts as Middlefield Banc Corp. or the Exchange Agent is required to deduct and withhold under the Internal Revenue Code of 1986 or under any other applicable provision of U.S. federal, state, local, or non-U.S. tax law. If properly withheld by Middlefield Banc Corp. or the Exchange Agent, the withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the Liberty Bank common stock.

3.4Reservation of Shares. Middlefield Banc Corp. will reserve for issuance a sufficient number of shares of Middlefield Banc Corp. common stock for issuing the Stock Consideration to Liberty Bank stockholders in accordance with this Article 3.

3.5Termination of Options and Phantom Stock. At the Effective Time all outstanding options, phantom stock rights, or other rights to acquire Liberty Bank common stock, whether vested or not vested, will be cancelled and will instead represent solely the right to receive in cash from Middlefield Banc Corp. the difference between $41.09 per share and, if less, the exercise or strike price of the option or right. The number and terms of options and rights will not exceed or differ from the number and terms disclosed in Liberty Bank Disclosure Schedule 4.2.1. If the exercise or strike price of an option or right equals or exceeds $41.09, the option or right will be cancelled without any payment in exchange. Middlefield Banc Corp. will deposit or cause to be deposited cash with the Exchange Agent for the benefit of the holders of options or rights. Middlefield Banc Corp. will cause the Exchange Agent to mail to each holder of options or rights within five Business Days after the Effective Time a form letter of transmittal for return to the Exchange Agent and instructions for surrendering the options or rights. Upon proper surrender of options or rights for exchange and cancellation to the Exchange Agent, together with a properly completed and duly executed letter of transmittal, the holder of the options or rights is entitled to receive in exchange the cash consideration specified in this Section 3.5, without interest.

4.5.2 Liberty Bank made available to Middlefield Banc Corp. the Liberty Bank Financial Statements for the periods through June 30, 2016. The Liberty Bank Financial Statements fairly present in each case in all material respects (subject in the case of unaudited interim statements to normal year-end adjustments) the financial position, results of operations, and cash flows of Liberty Bank and the Liberty Bank Subsidiaries as of and for the respective periods ending on the dates thereof, in accordance with GAAP during the periods involved, except as stated in the notes thereto, or in the case of unaudited statements as permitted by GAAP.

4.5.3 At the date of the most recent balance sheet included in the Liberty Bank Financial Statements or Liberty Bank Regulatory Reports Liberty Bank did not have any liabilities, obligations, or loss contingencies of any nature (whether absolute, accrued, contingent, or otherwise) of a type required to be presented in the Liberty Bank Financial Statements or Liberty Bank Regulatory Reports or in footnotes that are not fully presented or reserved against therein or fully disclosed in a footnote, except for liabilities, obligations, and loss contingencies that are not material individually or in the aggregate or that were incurred in the ordinary course of business consistent with past practice, and subject in the case of any unaudited statements to normal, recurring audit adjustments and absence of footnotes.

4.6.1 Liberty Bank and the Liberty Bank Subsidiaries are members of the same affiliated group within the meaning of Section 1504(a) of the Internal Revenue Code of 1986. On behalf of itself and the Liberty Bank Subsidiaries, Liberty Bank has timely filed or caused to be filed all Tax Returns (including but not limited to those filed on a consolidated, combined, or unitary basis) required to be filed by Liberty Bank and the Liberty Bank Subsidiaries before the date of this Agreement, or requests for extensions to file the returns and reports have been timely filed. All of Liberty Bank’s Tax Returns are true, correct, and complete in all material respects.

Liberty Bank and the Liberty Bank Subsidiaries have declared on their Tax Returns all positions taken that could result in substantial underpayment of United States Federal Income Tax within the meaning of Section 6662 of the Internal Revenue Code (or any corresponding provision of state or local laws). As of the most recent Liberty Bank Financial Statements, accrued but unpaid Taxes of Liberty Bank and the Liberty Bank Subsidiaries did not exceed the reserve for Tax liability (rather than any reserve for deferred Taxes established for timing differences between book and Tax income) included in the most recent balance sheet (rather than in any notes thereto). Liberty Bank and the Liberty Bank Subsidiaries are subject to Tax audits in the ordinary course of business. Liberty Bank management does not believe that an adverse resolution of Tax audits of which it has Knowledge would be reasonably likely to have a Material Adverse Effect on Liberty Bank. Liberty Bank and the Liberty Bank Subsidiaries have not been notified in writing by any jurisdiction that Liberty Bank or any Liberty Bank Subsidiary is required to file in the jurisdiction a Tax Return that has not been filed. Neither Liberty Bank nor any Liberty Bank Subsidiary is a member of a group that has filed or been included in a combined, consolidated, or unitary income Tax Return other than a group the common

parent of which is Liberty Bank or has any liability for Taxes of any Person other than Liberty Bank or a Liberty Bank Subsidiary under Treas. Reg. 1.1502-6 (or any similar provision of state, local, or non-U.S. law) as a transferee or successor, by contract, or otherwise. As of the date of this Agreement, all deficiencies proposed in writing as a result of audits have been paid or settled. There are no written claims or assessments pending against Liberty Bank or a Liberty Bank Subsidiary for an alleged deficiency in a Tax due, and neither Liberty Bank nor a Liberty Bank Subsidiary has been notified in writing of any proposed Tax claims or assessments against Liberty Bank or a Liberty Bank Subsidiary. Liberty Bank and the Liberty Bank Subsidiaries have duly and timely withheld, collected, and paid over to the appropriate taxing authority all amounts required to be withheld and paid under applicable laws, and duly and timely filed all Tax Returns for withheld Taxes within the time prescribed under applicable law. Liberty Bank has delivered to Middlefield Banc Corp. true and complete copies of all Tax Returns of Liberty Bank and Liberty Bank Subsidiaries for taxable periods ending on or after December 31, 2012. Neither Liberty Bank nor a Liberty Bank Subsidiary is or has been a party to a reportable transaction, as defined in Section 6707A(c)(1) of the Internal Revenue Code of 1986 and Treas. Reg. 1.6011-4 (b). Neither Liberty Bank nor a Liberty Bank Subsidiary has distributed stock of another Person or had stock distributed by another Person in a transaction purportedly or intended to be governed in whole or in part by Sections 355 or 361 of the Internal Revenue Code. Neither Liberty Bank nor a Liberty Bank Subsidiary has been a United States real property holding corporation within the meaning of Section 897(c)(2) of the Internal Revenue Code during the applicable period specified in Section 897(c)(1)(A)(ii).

4.6.2 Neither Liberty Bank nor any of the Liberty Bank Subsidiaries or Affiliates has taken or agreed to take any action, has failed to take any action, or knows of any fact, agreement, plan, or other circumstance that could reasonably be expected to prevent the Mergers from qualifying as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986.

4.7No Material Adverse Effect. To Liberty Bank’s Knowledge, since December 31, 2015 no event has occurred and no circumstance has arisen that has had or reasonably would be expected to have a Material Adverse Effect on Liberty Bank.

4.8.2 Subject to any consents that may be required as a result of the Mergers or other transactions under this Agreement, which required consents are identified in Liberty Bank Disclosure Schedule 4.8.2, to Liberty Bank’s Knowledge Liberty Bank is not in default under any material contract, agreement, commitment, arrangement, lease, insurance policy, or other instrument to which it is a party or by which its assets, business, or operations may be bound, and there has not occurred an event that, with the lapse of time, giving of notice, or both, would

constitute a default. Each real estate lease requiring consent of the lessor or its agent as a result of the Mergers or another form of change in control is identified in Liberty Bank Disclosure Schedule 4.8.2, identifying the section of the lease containing the consent requirement. Liberty Bank Disclosure Schedule 4.8.2 also identifies any other Liberty Bank contract (x) requiring consent of the other party or parties to the Mergers or another form of change in control or (y) for which The Middlefield Banking Company’s rights as successor to Liberty Bank may be adversely affected if the Mergers is undertaken without the consent of the other party or parties. Liberty Bank Disclosure Schedule 4.8.2, identifies the section of the contract requiring consent or having to do with The Middlefield Banking Company’s rights as successor.

4.8.3 True and correct copies of agreements, contracts, arrangements, and instruments referred to in Section 4.8.1 and 4.8.2 have been made available to Middlefield Banc Corp. on or before the date of this Agreement, and the agreements, contracts, arrangements, and instruments are in full force and effect on the date of this Agreement.

The most recent Performance Evaluation given to Liberty Bank under the Community Reinvestment Act of 1977 is Satisfactory or better.

4.11.4 Liberty Bank does not have Knowledge of any facts or circumstances that could form the reasonable basis for the assertion of any proceeding against Liberty Bank under any UDAP Law that, if determined adversely to Liberty Bank, would be likely to have a Material Adverse Effect.

4.11.5 Except as disclosed in Section 4.11 of the Liberty Bank Disclosure Schedule, to Liberty Bank’s Knowledge, and subject to regulatory confidentiality obligations, there (i) is no unresolved violation, criticism, or exception by any Bank Regulator with respect to any report or statement relating to any examinations or inspections of Liberty Bank, and (ii) are no notices or correspondence received by Liberty Bank with respect to formal or informal inquiries by, or disagreements or disputes with, any Bank Regulator with respect to Liberty Bank’s business, operations or policies since January 1, 2013.

Liberty Bank has no written or oral commitment to create an additional Liberty Bank Benefit Plan or materially modify, change, or renew an existing Liberty Bank Benefit Plan (a modification or change increasing the cost of a plan is deemed material), except as required to maintain qualified status. Liberty Bank has made available to Middlefield Banc Corp. true and complete copies of each Liberty Bank Benefit Plan.

4.12.2 All Liberty Bank Benefit Plans are in material compliance with (and have been managed and administered in accordance with) the applicable terms of ERISA, the Internal Revenue Code of 1986, and any other applicable laws. Except as stated in Liberty Bank Disclosure Schedule 4.12.2, each Liberty Bank Benefit Plan governed by ERISA and intended to be a qualified retirement plan under Section 401(a) of the Internal Revenue Code has either (1) received a favorable determination letter from the IRS (and Liberty Bank is not aware of any circumstances likely to result in revocation of a favorable determination letter) or timely application has been made therefor, or (2) is maintained under a prototype plan approved by the IRS and is entitled to rely upon the IRS National Office opinion letter issued to the prototype plan sponsor, or (3) is maintained under a volume submitter plan approved by the IRS and is entitled to rely upon the IRS National Office advisory letter issued to the volume submitter sponsor. To the Knowledge of Liberty Bank, there exists no fact that would adversely affect qualification of any of the Liberty Bank Benefit Plans intended to be qualified under Section 401(a) of the Internal Revenue Code, or any threatened or pending claim against any of the Liberty Bank Benefit Plans or their fiduciaries by any participant, beneficiary, or Governmental Entity (other than routine claims for benefits). Neither Liberty Bank nor a Liberty Bank Subsidiary has engaged in a transaction or omitted to take any action regarding a Liberty Bank Benefit Plan that would reasonably be expected to subject Liberty Bank or a Liberty Bank Subsidiary to a material unpaid tax or penalty imposed by Chapter 43 of the Internal Revenue Code or Sections 409 or 502 of ERISA.

4.12.3 No Liberty Bank Benefit Plan is a single employer pension plan (within the meaning of Section 4001(a)(15) of ERISA) for which Liberty Bank or an ERISA Affiliate could incur liability under Section 4063 or 4064 of ERISA or a plan maintained by more than one employer as described in Section 413(c) of the Internal Revenue Code of 1986. Except as stated in Liberty Bank Disclosure Schedule 4.12.3, neither Liberty Bank nor an ERISA Affiliate has ever maintained or contributed to a Liberty Bank Benefit Plan that is or was subject to Title IV of ERISA, Section 412 of the Internal Revenue Code, or Section 302 of ERISA or is a multiemployer plan (as defined in Section 3(37) of ERISA) and neither Liberty Bank, an ERISA Affiliate, nor any trust created thereunder, nor any trustee or administrator thereof, could reasonably be expected to be subject to either a civil liability or penalty under Section 409 or 502 of ERISA or a tax imposed under Chapter 43 of the Internal Revenue Code.

4.12.4 All material contributions required to be made under the terms of a Liberty Bank Benefit Plan have been timely made, and all anticipated contributions and funding obligations are accrued on Liberty Bank’s consolidated financial statements to the extent required by GAAP and Section 412 of the Internal Revenue Code of 1986. Liberty Bank and each Liberty Bank Subsidiary has expensed and accrued as a liability the present value of future benefits under each applicable Liberty Bank Benefit Plan for financial reporting purposes to the extent required by GAAP.

To Liberty Bank’s Knowledge, records regarding Liberty Bank Benefit Plans have been maintained in compliance with Section 107 of ERISA. To Liberty Bank’s Knowledge, neither Liberty Bank nor any other fiduciary (as that term is defined in ERISA Section 3(21)) for a Liberty Bank Benefit Plan has liability for a breach of fiduciary duties under Sections 404, 405 or 409 of ERISA. No Liberty Bank Benefit Plan fails to satisfy applicable requirements of Section 105(h)(2) of the Internal Revenue Code (determined without regard to whether the Liberty Bank Benefit Plan is self-insured).

4.12.6 Liberty Bank has furnished or otherwise made available to Middlefield Banc Corp. true and complete copies of (1) plan documents, summary plan descriptions, underlying participant distribution election forms, loan documents, loan amortization schedules, and benefit schedules (as applicable) for each written Liberty Bank Benefit Plan, (2) a summary of each unwritten Liberty Bank Benefit Plan (if applicable), (3) annual reports

There has been no communication to employees by Liberty Bank that would reasonably be expected to promise or guarantee retiree health, life, or disability insurance or retiree death benefits.

4.12.8 Except as stated in Liberty Bank Disclosure Schedule 4.12.8, neither execution and delivery of this Agreement nor consummation of the Mergers and other transactions under this Agreement will (1) result in a payment (including severance) becoming due to any director or employee of Liberty Bank under a Liberty Bank Benefit Plan, (2) increase benefits otherwise payable under a Liberty Bank Benefit Plan; or (3) result in acceleration of the time of payment or the vesting of any benefit. Except as stated in Liberty Bank Disclosure Schedule 4.12.8, no payment expected to be made by or from a Liberty Bank Benefit Plan will, either alone or together with any other payment, or could properly be characterized as an excess parachute payment under Section 280G of the Internal Revenue Code of 1986 or will or could, either individually or collectively, be a payment that is not deductible under Section 162(m) of the Internal Revenue Code.

4.12.9 Liberty Bank Disclosure Schedule 4.12.9 identifies each Liberty Bank Benefit Plan providing for the deferral of compensation and that may be subject to Internal Revenue Code Section 409A (“Liberty Bank Nonqualified Deferred Compensation Plan”) and the aggregate amounts deferred, if any, under each Liberty Bank Nonqualified Deferred Compensation Plan as of June 30, 2016. Each Liberty Bank Nonqualified Deferred Compensation Plan is maintained in material compliance with and has been managed and administered in accordance with and operated in compliance with Internal Revenue Code Section 409A.

4.12.10 There is not and has not been any trust or fund maintained by or contributed to by Liberty Bank or its employees to fund an employee benefit plan that would constitute a Voluntary Employees’ Beneficiary Association or a “welfare benefit fund” within the meaning of Section 419(a) of the Internal Revenue Code of 1986.

4.12.11 No claim, lawsuit, arbitration, or other action has been asserted or instituted or, to the Knowledge of Liberty Bank, has been threatened or is anticipated against any Liberty Bank Benefit Plan (other than routine claims for benefits and appeals of claims), Liberty Bank, any Liberty Bank Subsidiary, or any director, officer, or employee, or the assets of any trust of a Liberty Bank Benefit Plan.

4.12.12 Liberty Bank Disclosure Schedule 4.12.12 includes a schedule of all termination benefits and related payments payable to the individuals identified thereon under an employment agreement, change in control agreement, severance arrangement or policy, supplemental executive retirement plan, deferred bonus plan, deferred compensation plan, salary continuation plan, any material compensation arrangement, or other pension benefit or welfare benefit plan maintained by Liberty Bank for the benefit of officers, employees, or directors (the “Liberty Bank Benefits Schedule”), assuming their employment or service is terminated without cause as of December 31, 2016 and the Effective Time occurs on that date and based on other assumptions specified in the schedule.

5.11.3 Since January 1, 2013 neither Middlefield Banc Corp. nor a Middlefield Subsidiary has received written notification or any other communication from a Bank Regulator (1) asserting that Middlefield Banc Corp. or a Middlefield Subsidiary is not in material compliance with a statute, regulation, or ordinance the Bank Regulator enforces, (2) threatening to revoke a license, franchise, permit, or governmental authorization, (3) requiring or threatening to require Middlefield Banc Corp. or a Middlefield Subsidiary, or stating that Middlefield Banc Corp. or a Middlefield Subsidiary is required, to enter into a cease and desist order, agreement, or memorandum of understanding, or any other arrangement with a federal or state governmental agency or authority charged with supervision or regulation of banks or bank holding companies, or restricting or limiting or purporting to restrict or limit the operations of Middlefield Banc Corp. or a Middlefield Subsidiary, including without limitation a restriction on the payment of dividends, or (4) directing, restricting, or limiting or purporting to direct, restrict, or limit the operations of Middlefield Banc Corp. or a Middlefield Subsidiary.

5.12.1 Middlefield Disclosure Schedule 5.12.1 contains a list of all written and unwritten pension, retirement, profit-sharing, thrift, savings, deferred compensation, stock option, employee stock ownership, employee stock purchase, restricted stock, severance pay, retention, vacation, bonus or other incentive plans, all

employment, change in control, consulting, severance and retention agreements, all other written employee programs, arrangements or agreements, all medical, vision, dental, disability, life insurance, workers’ compensation, employee assistance or other health or welfare plans (including paid time-off policies and other material benefit policies and procedures), and all other employee benefit or fringe benefit plans, including “employee benefit plans” as that term is defined in Section 3(3) of ERISA, currently adopted, maintained by, sponsored in whole or in part by, or contributed to by Middlefield Banc Corp., a Middlefield Subsidiary, or an ERISA Affiliates for the benefit of employees, former employees, retirees (or dependents, including spouses, of the foregoing), directors, independent contractors, or other service providers to Middlefield Banc Corp. and under which employees, former employees, retirees, dependents, spouses, directors, or other service providers of Middlefield Banc Corp. are eligible to participate (collectively, “Middlefield Benefit Plans”). Middlefield Banc Corp. has no written or oral commitment to materially modify, change, or revise an existing Middlefield Benefit Plan, except as required to maintain qualified status. Middlefield Banc Corp. has made available to Liberty Bank true and complete copies of each Middlefield Benefit Plan.

5.12.2 All Middlefield Benefit Plans are in material compliance with (and have been managed and administrated in accordance with) applicable terms of ERISA, the Internal Revenue Code of 1986, and any other applicable laws. Except as stated in Middlefield Disclosure Schedule 5.12.2, each Middlefield Benefit Plan governed by ERISA and intended to be a qualified retirement plan under Section 401(a) of the Internal Revenue Code has either (1) received a favorable determination letter from the IRS (and Middlefield Banc Corp. is not aware of any circumstances likely to result in revocation of the favorable determination letter) or timely application has been made therefor, or (2) is maintained under a prototype plan approved by the IRS and is entitled to rely upon the IRS National Office opinion letter issued to the prototype plan sponsor. To the Knowledge of Middlefield Banc Corp., there exists no fact that would adversely affect the qualification of any of the Middlefield Benefit Plans intended to be qualified under Section 401(a) of the Internal Revenue Code, or any threatened or pending claim against any of the Middlefield Benefit Plans or their fiduciaries by any participant, beneficiary, or Governmental Entity (other than routine claims for benefits). Neither Middlefield Banc Corp. nor a Middlefield Subsidiary has engaged in a transaction or omitted to take an action regarding a Middlefield Benefit Plan that would reasonably be expected to subject Middlefield Banc Corp. or a Middlefield Subsidiary to a material unpaid tax or penalty imposed by Chapter 43 of the Internal Revenue Code or Sections 409 or 502 of ERISA.

5.12.3 No Middlefield Benefit Plan is a single employer pension plan (within the meaning of Section 4001 (a)(15) of ERISA) for which Middlefield Banc Corp. or an ERISA Affiliate could incur liability under Section 4063 or 4064 of ERISA or a plan maintained by more than one employer as described in Section 413(c) of the Internal Revenue Code. Except as stated in Middlefield Disclosure Schedule 5.12.3, neither Middlefield Banc Corp. nor an ERISA Affiliate has ever maintained or contributed to a Middlefield Benefit Plan that is or was subject to Title IV of ERISA, Section 412 of the Internal Revenue Code, or Section 302 of ERISA or is a multiemployer plan (as defined in Section 3(37) of ERISA) and neither Middlefield Banc Corp. nor an ERISA Affiliate, a trust created thereunder, nor any trustee or administrator thereof could reasonably be expected to be subject to either a civil liability or penalty under Section 409 or Section 502 of ERISA or a tax imposed under Chapter 43 of the Internal Revenue Code.

5.12.4 All material contributions required to be made under the terms of a Middlefield Benefit Plan have been timely made, and all anticipated contributions and funding obligations are accrued on Middlefield Banc Corp.’s consolidated financial statements to the extent required by GAAP and Section 412 of the Internal Revenue Code. Middlefield Banc Corp. and each Middlefield Subsidiary has expensed and accrued as a liability the present value of future benefits under each applicable Middlefield Benefit Plan for financial reporting purposes to the extent required by GAAP.

All reports, statements, returns, and other information required to be furnished or filed regarding Middlefield Benefit Plans have been timely furnished, filed, or both in

accordance with Sections 101 through 105 of ERISA and Sections 6057 through 6059 of the Internal Revenue Code, and they are true, correct, and complete. To Middlefield Banc Corp.’s Knowledge, records regarding Middlefield Benefit Plans have been maintained in compliance with Section 107 of ERISA. To Middlefield Banc Corp.’s Knowledge, neither Middlefield Banc Corp. nor any other fiduciary (as that term is defined in Section 3(21) of ERISA) for a Middlefield Benefit Plan has liability for a breach of fiduciary duties under Sections 404, 405 or 409 of ERISA. No Middlefield Benefit Plan fails to satisfy applicable requirements of Section 105(h)(2) of the Internal Revenue Code (determined without regard to whether the Middlefield Benefit Plan is self-insured).

5.12.6 Middlefield Banc Corp. has furnished or otherwise made available to Liberty Bank true and complete copies of (1) plan documents, summary plan descriptions, underlying participant distribution election forms, loan documents, loan amortization schedules, and benefit schedules (as applicable) for each written Middlefield Benefit Plan, (2) a summary of each unwritten Middlefield Benefit Plan (if applicable), (3) annual reports (Form 5500 series) for the three most recent years for each Middlefield Benefit Plan (if applicable), (4) actuarial valuation reports and financial statements as of the most recently completed plan year for each Middlefield Benefit Plan, including total accrued and vested liabilities, all contributions made by Middlefield Banc Corp., and assumptions on which the calculations are based, (5) all related trust agreements, insurance contracts, or other funding agreements currently implementing the Middlefield Benefit Plans (if applicable), (6) the most recent IRS determination letter for each tax- qualified Middlefield Benefit Plan (or, for a Middlefield Benefit Plan maintained under a pre-approved prototype or volume submitter plan, the IRS determination letter on the pre-approved plan), and (7) all substantive correspondence relating to any liability of or non-compliance relating to any Middlefield Benefit Plan addressed to or received from the IRS, the Department of Labor, or any other Governmental Entity within the past three years.

5.12.7 Except as stated in Middlefield Disclosure Schedule 5.12.7, Middlefield Banc Corp. has no liability for retiree health, life, or disability insurance or any retiree death benefits under any Middlefield Benefit Plan other than benefits required under COBRA or similar state laws. There has been no communication to employees by Middlefield Banc Corp. that would reasonably be expected to promise or guarantee retiree health, life, or disability insurance or retiree death benefits.

5.12.8 No claim, lawsuit, arbitration, or other action has been asserted, instituted or, to the Knowledge of Middlefield Banc Corp., threatened or is anticipated against any Middlefield Benefit Plan (other than routine claims for benefits and appeals of claims), Middlefield Banc Corp., any Middlefield Subsidiary, or any director, officer, or employee, or the assets of any trust of a Middlefield Benefit Plan.

7.10.1 Middlefield Banc Corp. and The Middlefield Banking Company shall endeavor to retain as many of the current officers and employees of Liberty Bank as is commercially reasonable and possible in light of its banking template and post-Mergers business plans. It is understood and agreed that nothing in this Section 7.10.1 or elsewhere in this Agreement shall be deemed to be a contract of employment or be construed to give said employees any rights other than as employees at will under Ohio law and said employees shall not be deemed to be third-party beneficiaries of this provision. Liberty Bank employees who become employees of Middlefield Banc Corp. or The Middlefield Banking Company after the Effective Time (“Continuing Employees”) will be eligible to participate in any Middlefield Benefit Plan of similar character available to other employees of Middlefield Banc Corp. or The Middlefield Banking Company (other than any nonqualified deferred compensation plan or agreement, employment agreement, or change in control agreement). Solely for purposes of determining eligibility for and any applicable vesting period (and not for benefit accrual purposes), Continuing Employees who become participants in a Middlefield Benefit Plan will receive credit for eligibility and vesting requirements for service as Liberty Bank employees before the Effective Time. This Agreement does not restrict the ability of Middlefield Banc Corp. or The Middlefield Banking Company from and after the Effective Time to terminate employment of any Liberty Bank employee. Except for contractual commitments, if any, specifically made or assumed by Middlefield Banc Corp. under this Agreement or by operation of law, neither Middlefield Banc Corp. nor any Middlefield Subsidiary is obliged after the Effective Time to continue the employment or particular job responsibilities or specified level of compensation, benefits, or perquisites of any Person employed by Liberty Bank at the Effective Time.

The estimated amounts payable under the employment and change in control severance agreements are stated in the Liberty Bank Benefits Schedule in Liberty Bank Disclosure Schedule 4.12.12. Despite anything in this Agreement to the contrary, however, Middlefield Banc Corp. is not required to make and Middlefield Banc Corp. will not make a payment that would constitute a “parachute payment” (as that term is defined in Internal Revenue Code Section 280G and Internal Revenue Service implementing regulations). If a payment would constitute a parachute payment, the payment will be reduced to one dollar less than the amount beyond which the payment would be considered a parachute payment. As a condition to entitlement to change-in-control payments or severance payment under an

agreement identified in Liberty Bank Disclosure Schedule 4.12.1, the Liberty Bank executive identified in Liberty Bank Disclosure Schedule 4.12.1 must agree to comply with the noncompete and nonsolicitation restrictions on terms comparable to the noncompete and nonsolicitation restrictions stated in the agreement identified in Liberty Bank Disclosure Schedule 4.12.1.

As a condition to entitlement to severance pay, Employees must execute appropriate release of claims documents. For purposes of this provision, cause means termination because of material neglect of or material refusal to perform any duty or responsibility as an employee other than as a result of sickness, accident, or similar cause beyond an employee’s reasonable control, dishonesty, commission of a crime (other than minor traffic violations), or misconduct. Severance under this Section 7.10.3 is one (1) week of base pay for each full year of service (including service with Liberty Bank, Middlefield Banc Corp., or a subsidiary of either), with a minimum of 4 weeks and a maximum of 26 weeks of base pay. For purposes of this provision, base pay means base salary before pre-tax deductions for a salaried employee, and for an hourly employee the employee’s total scheduled hours (prorated, as appropriate) before any pre- tax deductions for the 12 full calendar months preceding the month in which the Effective Time occurs. In addition to severance under this Section 7.10.3, Middlefield Banc Corp. may pay retention or other incentive bonuses to Liberty Bank employees identified by Middlefield Banc Corp. after consulting with Liberty Bank, as critical to data processing or other transition tasks or who are otherwise determined by Middlefield Banc Corp. to be key officers or employees. Retention bonuses may have a vesting term of up to two years, with bonus forfeiture occurring for termination before vesting. Retention bonuses, if any, would be in addition to any bonus for which any former Liberty Bank officer or employee may be eligible as an employee of Middlefield Banc Corp. or The Middlefield Banking Company.

7.10.4 Middlefield Banc Corp. will make available to any Person who is an employee of Liberty Bank at the Effective Time but whose employment does not continue with Middlefield Banc Corp. or The Middlefield Banking Company after the Effective Time or whose employment is terminated within one year after the Effective Time, (excluding any employee terminated for cause), career placement counseling and professional counseling services through Middlefield Banc Corp.’s employee assistance program.

Valerian and Bevan to serve as directors of Middlefield Banc Corp. immediately after the Effective Time. If, prior to the Effective Time, either Messrs.

Middlefield Banc Corp. also will maintain after the Effective Time a Northeast Ohio Advisory Board. Prior to the Effective Time, Middlefield Banc Corp. will consult with the Liberty Bank Board of Directors about the composition of the Northeast Ohio Advisory Board.

7.12.1 For six years after the Effective Time, Middlefield Banc Corp. will maintain directors’ and officers’ liability insurance for actions, omissions, or events occurring before the Effective Time, covering persons who on the date of this Agreement are covered by Liberty Bank’s current directors’ and officers’ liability insurance

policy. The coverage will be on terms substantially equivalent to the terms of Liberty Bank’s coverage on the date of this Agreement; provided, however, Middlefield Banc Corp. is not required to expend annually under this Section 7.12.1 an amount exceeding 150% of Liberty Bank’s cost for directors’ and officers’ liability insurance coverage on the date of this Agreement as set forth on Liberty Bank Disclosure Schedule 7.12.1 (the “Maximum Amount”). If the cost of coverage exceeds the Maximum Amount, Middlefield Banc Corp. will instead maintain the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to the Maximum Amount. Instead of the directors’ and officers’ liability insurance coverage outlined in this Section 7.12.1, Middlefield Banc Corp., or Liberty Bank with the consent of Middlefield Banc Corp., which consent will not be unreasonably withheld, may obtain at or before the Effective Time a prepaid tail policy providing single-limit equivalent coverage to that described in this Section 7.12.1 for a per annum premium cost not to exceed 150% of the annual premium most recently paid by Liberty Bank. Written evidence of the directors’ and officers’ liability insurance coverage secured pursuant to this Section 7.12.1 will be provided to the Liberty Bank directors and officers at Closing. So that Middlefield Banc Corp. may fulfill its agreement to provide directors’ and officers’ liability insurance policies for six years, Liberty Bank agrees to provide the insurer or substitute insurer with such representations as the insurer may reasonably request for reporting of prior claims.

7.12.2 In addition to Section 7.12.1, Middlefield Banc Corp. will for six years after the Effective Time and to the fullest extent permitted under applicable law and Liberty Bank’s articles of association and bylaws indemnify, defend, and hold harmless each Person who is on the date of this Agreement, who has been at any time before the date hereof, or who before the Effective Time becomes an officer, director or employee of Liberty Bank, or a Liberty Bank Subsidiary (“Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorneys’ fees), liabilities, judgments, or amounts that are paid in settlement (provided settlement occurred with the advance written consent of Middlefield Banc Corp., not unreasonably withheld, conditioned, or delayed) of or for any claim, action, suit, proceeding, or investigation, whether civil, criminal, or administrative (“Claim”) in which an Indemnified Party is or is threatened to be made a party or witness in whole or in part or arising in whole or in part on account of the Person being or having been an officer or director of Liberty Bank or serving or having before the Effective Time at the request of any such party as a director, officer, employee, trustee, or partner of another Person or benefit plan if the Claim pertains to any matter of fact arising, existing, or occurring before the Effective Time (including without limitation the Mergers and the other transactions under this Agreement), regardless of whether the Claim is asserted or claimed before or after the Effective Time. An Indemnified Party wishing to claim indemnification under this Section 7.12.2 must upon learning of the notify Middlefield Banc Corp., but failure to notify Middlefield Banc Corp. does not relieve Middlefield Banc Corp. from liability it may have under this Section 7.12.2 unless failure to notify Middlefield Banc Corp. materially prejudices Middlefield Banc Corp. If a Claim is made before or after the Effective Time Middlefield Banc Corp. may assume the defense (and the Indemnified Parties will cooperate in the defense), and Middlefield Banc Corp. is not liable to any Indemnified Party for legal expenses of other counsel or other expenses subsequently incurred by any Indemnified Party. If Middlefield Banc Corp. elects not to assume the defense, or if counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are or may be (regardless of whether any have yet actually arisen) issues raising conflicts of interest between Middlefield Banc Corp. and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Middlefield Banc Corp. is responsible for paying reasonable fees and expenses of counsel for the Indemnified Parties. Middlefield Banc Corp. is obligated for no more than one counsel for all Indemnified Parties unless there is a conflict of interest requiring more than one counsel. Middlefield Banc Corp. is not liable for any settlement effected without its advance written, which consent may not be unreasonably withheld, conditioned, or delayed. Middlefield Banc Corp. will advance expenses as incurred in each case upon receipt of an undertaking from the Indemnified Party to repay advanced expenses if it is determined by a final and nonappealable judgment of a court of competent jurisdiction that the Indemnified Party is not entitled to indemnification.

7.12.3 If either Middlefield Banc Corp. or a successor or assign of Middlefield Banc Corp. consolidates with or merges into another Person and is not the continuing or surviving company or entity or transfers all or substantially all of its properties and assets to a Person, proper provision will be made so that the surviving company or entity or transferee assumes the obligations of

7.12.4 Middlefield Banc Corp.’s obligations under this Section 7.12 are enforceable against Middlefield Banc Corp. directly by the Indemnified Parties and are binding on all respective successors and permitted assigns of Middlefield Banc Corp.

7.13Communications to Employees; Training. With a representative of Liberty Bank permitted to attend, Middlefield Banc Corp. will meet with Liberty Bank employees to discuss this Agreement as promptly as practicable after execution of this Agreement, meeting at such locations as Middlefield Banc Corp. and Liberty Bank mutually agree. Middlefield Banc Corp. and Liberty Bank will agree in advance about the scope and content of communications to Liberty Bank employees regarding this Agreement. At mutually agreed times after execution of this Agreement and with a representative of Liberty Bank permitted to attend, representatives of Middlefield Banc Corp. may meet with Liberty Bank employees to discuss employment opportunities. From and after the first date on which Regulatory Approvals and Liberty Bank Stockholder Approval are obtained, for the benefit of Liberty Bank employees Middlefield Banc Corp. may conduct training sessions outside of normal business hours or at other times as Liberty Bank agrees and may conduct training seminars at any branch location of Liberty Bank. Middlefield Banc Corp. will in good faith attempt to schedule training sessions in a manner not unreasonably interfering with Liberty Bank’s normal business operations.

7.14Exemption from Liability Under Section 16(b). Middlefield Banc Corp. shall take all steps as may be necessary or appropriate to cause the transactions contemplated by Article 3 and any other acquisitions of equity securities of Middlefield Banc Corp. in connection with the consummation of the transactions contemplated by this Agreement to be exempt under Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended.

If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party based on authorship of any of the provisions of this Agreement.

11.10Specific Performance. The parties hereto agree that irreparable damage will occur if the provisions contained in this Agreement are not performed in accordance with their specific terms or are otherwise breached. It is therefore agreed that the parties are entitled to an injunction or injunctions, without posting bond or other security, to prevent breaches of this Agreement and to enforce specifically the terms and provisions in any court of the United States or any state having jurisdiction, except where another remedy is expressly provided by this Agreement. Each party agrees that it will not seek and will agree to waive any requirement for securing or posting bond in the other party’s seeking or obtaining such relief.

11.11Waiver of Trial by Jury. The parties hereto hereby knowingly, voluntarily and intentionally waive the right any may have to a trial by jury in any litigation based on or rising out of or under this Agreement and any agreement to be executed in accordance with this Agreement, or any course of conduct, course of dealing, statements (whether verbal or written) or actions of either party.

11.12Amendment and Waiver. (a) Whether before or after Liberty Bank Stockholder Approval or Middlefield Shareholder Approval is obtained, by action of the Board of Directors of each of Liberty Bank, Middlefield Banc Corp., and The Middlefield Banking Company, this Agreement may be amended by an instrument in writing signed by Liberty Bank, Middlefield Banc Corp., and The Middlefield Banking Company.

However, after approval of this Agreement and the Mergers by Liberty Bank stockholders, without further Liberty Bank Stockholder Approval an amendment of this Agreement is not effective if the amendment decreases the amount or value of Merger Consideration or changes the form of Merger Consideration.

(b) By action of its Board of Directors, Liberty Bank may (x) waive compliance with any of the agreements or conditions of Middlefield Banc Corp. and The Middlefield Banking Company, (y) waive any inaccuracies in the representations and warranties of Middlefield Banc Corp. and The Middlefield Banking Company, or (z) extend the time for performance of the obligations of Middlefield Banc Corp. and The Middlefield Banking Company. By action of the Board of Directors of each company, Middlefield Banc Corp. and The Middlefield Banking Company may (x) waive compliance with any of the agreements or conditions of Liberty Bank, (y) waive any inaccuracies in the representations and warranties of Liberty Bank, or (z) extend the time for performance of the obligations of Liberty Bank. An extension or waiver by a party is effective if and only if the extension or waiver is in writing and is signed by the party. A party’s failure to insist on strict compliance with an obligation, covenant, agreement, or condition is not a waiver of subsequent noncompliance.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement by their duly authorized officers as of the date first written above.

	President and Chief Executive Officer		Chairman, President, and Chief Executive Officer

Upon formation of MBC Interim Bank, MBC Interim Bank shall sign and become a party to this Agreement.

Concurrently with the execution of this letter agreement (“Voting Agreement”), Middlefield Banc Corp., The Middlefield Banking Company, and Liberty Bank, N.A. (“Liberty Bank”), are entering into an Agreement and Plan of Reorganization dated the date of this Voting Agreement (the “Merger Agreement”), whereby Liberty Bank will merge into The Middlefield Banking Company (the “Merger”) and stockholders of Liberty Bank will receive cash and shares of Middlefield Banc Corp. common stock on terms stated in the Merger Agreement, subject to closing of the Merger. All defined terms used but not defined in this Voting Agreement have the meanings given in the Merger Agreement.

A condition to Middlefield Banc Corp.’s obligations under the Merger Agreement is that I execute and deliver this Voting Agreement to Middlefield Banc Corp.

(a) As of the date of this Voting Agreement I have, and at all times during the term of this Voting Agreement I will have, beneficial ownership of, and good and valid title to, shares of Liberty Bank common stock, par value $10.00 per share. I hold options or rights to acquire shares of Liberty Bank common stock. All of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock are owned free and clear of any proxy or voting restriction, claims, liens, encumbrances, and security interests and any other limitation or restriction whatsoever (including any restriction on the right to dispose of the securities). None of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock are subject to a voting trust or other agreement or arrangement regarding voting rights of the securities. For purposes of this Voting Agreement beneficial ownership is defined in Rule 13d-3 under the Securities Exchange Act of 1934.

(b) Except for the shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock stated in paragraph (a), as of the date of this Voting Agreement I do not beneficially own any (x) shares of capital stock or voting securities of Liberty Bank, (y) securities of Liberty Bank convertible into or exchangeable for shares of capital stock or voting securities of Liberty Bank or (z) options or other rights to acquire from Liberty Bank any capital stock, voting securities, or securities convertible into or exchangeable for capital stock or voting securities of Liberty Bank. The shares of Liberty Bank common stock identified in paragraph (a), together with all shares of Liberty Bank common stock I acquire during the term of this Voting Agreement, including through exercise of options or rights, are subject to the terms of this Voting Agreement.

(c) At the Liberty Bank Stockholder Meeting at which the Merger Agreement and the Merger will be voted upon, and on every action or approval by written consent of stock of Liberty Bank, I will vote or cause to be voted all shares over which I have voting power to be voted in favor of approval and adoption of the Merger Agreement, the Merger, and other transactions under the Merger Agreement and in favor of any proposal to adjourn or postpone the meeting to a later date if there are not sufficient votes to approve the Merger Agreement, the Merger, and other transactions under the Merger Agreement.

(d) During the term of this Voting Agreement I will not offer, sell, transfer, pledge, encumber, or otherwise dispose of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock (or interest therein), and I will use my best efforts to not permit the offer, sale, transfer, pledge, encumbrance, or other disposition of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, except as may be permitted by paragraph (g).

(e) I agree that Liberty Bank is not bound by any attempted sale of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, and Liberty Bank’s transfer agent will receive appropriate stop transfer orders and is not required to register any such attempted sale of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, unless the sale is effected in compliance with this Voting Agreement.

(f) I have the legal capacity to enter into this Voting Agreement. I have duly and validly executed and delivered this Voting Agreement. This Voting Agreement is a valid and binding obligation enforceable against me in accordance with its terms, subject to bankruptcy, insolvency, and other laws affecting creditors’ rights and general equitable principles. No consent of my spouse, (if any), is necessary under any community property or other law in order for me to enter into and perform my obligations under this Voting Agreement.

(g) I may offer, sell, transfer, pledge, encumber, or otherwise dispose of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock to my spouse, children, or grandchildren, but to do so I must first cause the person to whom I transfer the securities to execute and deliver to Middlefield Banc Corp. an agreement to be bound by the terms of this Voting Agreement. A transfer not preceded by the transferee’s executed Voting Agreement delivered to Middlefield Banc Corp. is not valid or effective and will not be honored.

I am signing this Voting Agreement solely in my capacity as a stockholder of Liberty Bank, and as an option holder if I hold options or rights to acquire Liberty Bank common stock. I am not signing this Voting Agreement in any other capacity, such as a director or officer of Liberty Bank or as a fiduciary of any trusts in which I am not a beneficiary. I make no agreement in this Voting Agreement in any capacity other than in my capacity as a beneficial owner of Liberty Bank common stock. Nothing in this Voting Agreement limits or affects any action or inaction by me or any of my representatives, as applicable, as a director or officer of Liberty Bank or affects my rights to exercise my fiduciary duties pursuant to Section 8.2(b) of the Merger Agreement.

This Voting Agreement terminates and is of no further force and effect on the earliest to occur of (a) the favorable vote of Liberty Bank stockholders for approval and adoption of the Merger Agreement and the Merger, (b) the Effective Time, (c) Middlefield Banc Corp. and I enter into a written agreement to terminate this Voting Agreement, or (d) any termination of the Merger Agreement in accordance with its terms, except that termination is without prejudice to Middlefield Banc Corp.’s rights if termination is a result of my willful breach of any covenant or representation in this Voting Agreement.

All notices and other communications under this Voting Agreement must be in writing and will be deemed given if delivered personally, sent by facsimile, mailed by registered or certified mail return receipt requested, or delivered by an express courier, to the other party at its addresses contained on the signature page.

This Voting Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties. This Voting Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, between the parties concerning the subject matter of this Voting Agreement.

I agree and acknowledge that Middlefield Banc Corp. may be irreparably harmed by, and that there is no adequate remedy at law for, a violation of this Voting Agreement by me. Without limiting other remedies, Middlefield Banc Corp. is entitled to enforce this Voting Agreement by specific performance or injunctive relief. This Voting Agreement and all claims arising hereunder or relating hereto are governed by and will be construed and enforced in accordance with the laws of the State of Ohio, without giving effect to the State of Ohio principles of conflicts of law. I hereby irrevocably and unconditionally submit to the exclusive jurisdiction of any Ohio state court or the United States District Court for the Northern District of Ohio in any action or proceeding arising out of or relating to this Voting Agreement.

If a term, provision, covenant, or restriction of this Voting Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void, or unenforceable, the remainder of the terms, provisions, covenants, and restrictions of this Voting Agreement remain in full force and effect and are not affected, impaired, or invalidated so long as the effect on the economic or legal substance is not materially adverse to a party. If a term, provision, covenant, or restriction of this Voting Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void, or unenforceable, the parties will negotiate in good faith to modify this Voting Agreement to effect the original intent of the parties as closely as possible.

This Voting Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed is deemed to be an original but all of which taken together constitute a single instrument.

(b) Liability of consolidated association; capital stock; dissenting shareholders

The consolidated association shall be liable for all liabilities of the respective consolidating banks or associations. The capital stock of such consolidated association shall not be less than that required under existing law for the organization of a national bank in the place in which it is located:Provided, That if such consolidation shall be voted for at such meetings by the necessary majorities of the shareholders of each association and State bank proposing to consolidate, and thereafter the consolidation shall be approved by the Comptroller, any shareholder of any of the associations or State banks so consolidated who has voted against such consolidation at the meeting of the association or bank of which he is a stockholder, or who has given notice in writing at or prior to such meeting to the presiding officer that he dissents from the plan of consolidation, shall be entitled to receive the value of the shares so held by him when such consolidation is approved by the Comptroller upon written request made to the consolidated association at any time before thirty days after the date of consummation of the consolidation, accompanied by the surrender of his stock certificates.

The value of the shares of any dissenting shareholder shall be ascertained, as of the effective date of the consolidation, by an appraisal made by a committee of three persons, composed of (1) one selected by the vote of the holders of the majority of the stock, the owners of which are entitled to payment in cash; (2) one selected by the directors of the consolidated banking association; and (3) one selected by the two so selected. The valuation agreed upon by any two of the three appraisers shall govern. If the value so fixed shall not be satisfactory to any dissenting shareholder who has requested payment, that shareholder may, within five days after being notified of the appraised value of his shares, appeal to the Comptroller, who shall cause a reappraisal to be made which shall be final and binding as to the value of the shares of the appellant.

(d) Appraisal by Comptroller; expenses of consolidated association; sale and resale of shares; State appraisal and consolidation law

If, within ninety days from the date of consummation of the consolidation, for any reason one or more of the appraisers is not selected as herein provided, or the appraisers fail to determine the value of such shares, the Comptroller shall upon written request of any interested party cause an appraisal to be made which shall be final and binding on all parties. The expenses of the Comptroller in making the reappraisal or the appraisal, as the case may be, shall be paid by the consolidated banking association. The value of the shares ascertained shall be promptly paid to the dissenting shareholders by the consolidated banking association. Within thirty days after payment has been made to all dissenting shareholders as provided for in this section the shares of stock of the consolidated banking association which would have been delivered to such dissenting shareholders had they not requested payment shall be sold by the consolidated banking association at an advertised public auction, unless some other method of sale is approved by the Comptroller, and the consolidated banking association shall have the right to purchase any of such shares at such public auction, if it is the highest bidder therefor, for the purpose of reselling such shares within thirty days thereafter to such person or persons and at such price not less than par as its board of directors by resolution may determine. If the shares are sold at public auction at a price greater than the amount paid to the dissenting shareholders the excess in such sale price shall be paid to such shareholders. The appraisal of such shares of stock in any State bank shall be determined in the manner prescribed by the law of the State in such cases, rather than as provided in this section, if such provision is made in the State law; and no such consolidation shall be in contravention of the law of the State under which such bank is incorporated.

You have requested our opinion as to the fairness, from a financial point of view, to the holders of shares of issued and outstanding common stock, $10.00 par value (the “Company Common Shares”), of Liberty Bank, National Association (“Liberty”) of the Merger Consideration (as defined below) to be received by such holders in the proposed merger (the “Proposed Merger”) of MBC Interim Bank., a wholly-owned subsidiary of Middlefield Banc Corp., with and into Liberty as set forth in the Agreement and Plan of Reorganization dated July 27, 2016 (the “Merger Agreement”). Middlefield Banc Corp. and MBC Interim Bank are referred to individually and collectively herein as “MBCN.” As detailed in the Merger Agreement, pursuant to the Proposed Merger, each Company Common Share issued and outstanding immediately prior to the effective time of the Proposed Merger will be converted, at the election of the holder thereof (subject to the cash/stock aggregate consideration provisions of the Merger Agreement), into the right to receive $37.96 in cash or 1.1934 shares of MBCN common stock, no par value, in addition to a cash special dividend of approximately $3.13 per share (the “Merger Consideration”).

In arriving at our opinion, we have, among other things: (i) reviewed the historical financial performance, current financial position and general prospects of each of MBCN and Liberty and reviewed certain internal financial analyses and forecasts prepared by the respective management teams of MBCN and Liberty, (ii) reviewed the Merger Agreement, (iii) reviewed and analyzed the stock performance and trading history of MBCN, (iv) studied and analyzed the consolidated financial and operating data of MBCN and Liberty, (v) reviewed the pro forma financial impact of the Proposed Merger on MBCN, based on assumptions relating to transaction expenses, purchase accounting adjustments, cost savings and other synergies determined by the respective management teams of MBCN and Liberty, (vi) considered the financial terms of the Proposed Merger as compared with the financial terms of comparable bank and bank holding company mergers and acquisitions, (vii) met and/or communicated with certain members of each of MBCN’s and Liberty’s senior management to discuss their respective operations, historical financial statements and future prospects, and (viii) conducted such other financial analyses, studies and investigations as we deemed appropriate.

Our opinion is given in reliance on information and representations made or given by MBCN, Liberty, and their respective officers, directors, auditors, counsel and other agents, and on filings, releases and other information issued by each of MBCN and Liberty, including financial statements and financial projections, stock price data, as well as certain other information from recognized independent sources. We have not independently verified the information or data concerning MBCN or Liberty nor any other data we considered in our review and, for purposes of the opinion set forth below, we have assumed and relied upon the accuracy and completeness of all

such information and data. We have assumed that all forecasts and projections provided to us have been reasonably prepared and reflect the best currently available estimates and good faith judgments of the respective management teams of MBCN and Liberty as to their most likely future financial performance. We express no opinion as to any financial projections or the assumptions on which they are based. We have not conducted any valuation or appraisal of any assets or liabilities of MBCN or Liberty, nor have any such valuations or appraisals been provided to us. Additionally, we assume that the Proposed Merger is, in all respects, lawful under applicable law.

With respect to anticipated transaction costs, purchase accounting adjustments, expected cost savings and other synergies and financial and other information relating to the general prospects of MBCN and Liberty, we have assumed that such information has been reasonably prepared and reflects the best currently available estimates and good faith judgment of the respective management teams of MBCN and Liberty as to their most likely future performance. We have further relied on the assurances of the respective management teams of MBCN and Liberty that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We have assumed that the allowance for loan losses indicated on the balance sheet of each of MBCN and Liberty is adequate to cover such losses; we have not reviewed loans or credit files of MBCN or Liberty. We have assumed that all of the representations and warranties contained in the Merger Agreement and all related agreements are true and correct, that each party under the agreements will perform all of the covenants required to be performed by such party under the agreements, and that the conditions precedent in the agreements will not be waived. Also, in rendering our opinion, we have assumed that in the course of obtaining the necessary regulatory approvals for the consummation of the Proposed Merger, no conditions will be imposed that will have a material adverse effect on the combined entity or contemplated benefits of the Proposed Merger, including the cost savings and related expenses expected to result from the Proposed Merger.

Our opinion is based upon information provided to us by the respective management teams of MBCN and Liberty, as well as market, economic, financial and other conditions as they exist and can be evaluated only as of the date hereof and accordingly, it speaks to no other period. We have not undertaken to reaffirm or revise this opinion or otherwise comment on events occurring after the date hereof and do not have an obligation to update, revise or reaffirm our opinion. Our opinion does not address the relative merits of the Proposed Merger or the other business strategies that Liberty’s Board of Directors has considered or may be considering, nor does it address the underlying business decision of Liberty’s Board of Directors to proceed with the Proposed Merger. We were not asked to and did not solicit or explore other strategic alternatives to the Proposed Merger. We are expressing no opinion as to the prices at which MBCN’s securities may trade at any time. Nothing in our opinion is to be construed as constituting tax advice or a recommendation to take any particular tax position, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that MBCN has obtained such advice as it deemed necessary from qualified professionals. Our opinion is for the information of Liberty’s Board of Directors in connection with its evaluation of the Proposed Merger and does not constitute a recommendation to the Board of Directors of Liberty in connection with the Proposed Merger or a recommendation to any shareholder of Liberty as to how such shareholder should vote or act with respect to the Proposed Merger. This opinion should not be construed as creating any fiduciary duty on Boenning & Scattergood, Inc.’s part to any party or person. Our opinion is not to be quoted or referred to, in whole or in part, in a registration statement, prospectus, proxy statement or in any other document, nor shall this opinion be used for any other purpose, without our prior written consent, except that, if required by applicable

law, this opinion may be referenced and included in its entirety in any filing made by MBCN in respect to the Proposed Merger with the Securities and Exchange Commission; provided, however, any description of or reference to our opinion or to Boenning & Scattergood, Inc. be in a form reasonably acceptable to us and our counsel. We shall have no responsibility for the form or content of any such disclosure, other than the opinion itself.

Boenning & Scattergood, Inc., as part of its investment banking business, regularly is engaged in the valuation of assets, securities and companies in connection with various types of transactions, including mergers, acquisitions, private placements, public offerings and valuations for various other purposes, and in the determination of adequate consideration in such transactions. In the ordinary course of our business as a broker-dealer, we may, from time to time, purchase securities from, and sell securities to, MBCN, Liberty, and/or their respective affiliates. In the ordinary course of business, we may also actively trade the securities of MBCN for our own account and/or for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

We are acting as Liberty’s financial advisor in connection with the Proposed Merger and will receive a fee for our services, a significant portion of which is contingent upon consummation of the Proposed Merger. We will also receive a fee for rendering this opinion. Our fee for rendering this opinion is not contingent upon any conclusion that we may reach or upon completion of the Proposed Merger. Liberty has also agreed to indemnify us against certain liabilities that may arise out of our engagement.

Boenning & Scattergood, Inc. was engaged in February 2016 by MBCN to serve as placement agent for a private placement of common stock. The offering ultimately closed on June 30, 2016, and Boenning & Scattergood, Inc. was paid a commission for its role. Boenning & Scattergood, Inc., advised, and received compensation from, Liberty in 2014 relating to the exploration of strategic alternatives, although no transaction was consummated at that time.

Except for the arrangements between Boenning & Scattergood, Inc. and Liberty described in the preceding paragraphs, Boenning & Scattergood, Inc. has not had any material relationship with Liberty during the past two years in which compensation was received or was intended to be received. Boenning & Scattergood, Inc. may provide services to MBCN in the future (and/or to Liberty if the Proposed Merger is not consummated), although as of the date of this opinion, there is no agreement to do so nor any mutual understanding that such services are contemplated.

This opinion has been approved by Boenning & Scattergood, Inc.’s fairness opinion committee. We do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Proposed Merger by any of the officers, directors, or employees of any party to the Merger Agreement, or any class of such persons, relative to the compensation to be received by the holders of Company Common Shares in the Proposed Merger.

Based on and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration to be received by the holders of Company Common Shares pursuant to the Merger Agreement is fair, from a financial point of view, to such holders.

Middlefield Banc Corp., holding company of The Middlefield Banking Company (collectively “MBCN” or the “Company”), has agreed to enter into an agreement and plan of reorganization (the “Agreement”), with Liberty Bank, N.A. (“Liberty”), and MBC Interim Bank pursuant to which the issued and outstanding shares of the capital stock of Liberty (which total 959,283 as of the date of this letter) will be acquired by MBCN in a transaction (the “Acquisition”) for which MBCN will issue stock consideration to Liberty shareholders at a fixed exchange ratio of 1.1934x or cash consideration of $37.96 per share, subject to proration to ensure that, in the aggregate, 45% of Liberty’s shares of common stock outstanding are converted into MBCN’s common stock for each share of Liberty common stock issued and outstanding (the “Merger Consideration”) as defined in the Agreement. In addition, and immediately prior to closing of the Acquisition, Liberty will declare a special cash dividend (“Special Dividend”) to be paid to Liberty shareholders in the amount of $3,000,000, or approximately $3.13 per share. Pursuant to the Agreement and assuming an MBCN stock price of $31.81 per share, the total consideration (Merger Consideration plus Special Dividend, together “Total Consideration”) to Liberty shareholders amounts to $41.09 per share, or $39,415,269. Additionally, Liberty has 91,561 stock options and phantom stock outstanding with a weighted average strike price of approximately $28.56 that will be cashed out at closing. The value of the stock option and phantom stock consideration is calculated by taking the difference between the consideration per share price of $41.09 and the weighted average strike price of $28.56, multiplied by the 91,561 stock options and phantom stock equaling $1,147,357 in stock option and phantom stock consideration. When added to the Total Consideration of $39,415,269, the aggregate value of the transaction consideration (the “Transaction Consideration”) is $40,562,627, including stock options and phantom stock, or $42.28 per share.

You have asked us whether, in our opinion, the Transaction Consideration is fair to the shareholders of MBCN from a financial point of view.

Donnelly Penman & Partners Inc. (“Donnelly Penman”) is an investment banking firm of recognized standing. As part of our investment banking services, we are continually engaged in the valuation of businesses and securities in connection with mergers and acquisitions, secondary distributions of securities, private placements and valuations for going private transactions, corporate and other purposes.

On April 19, 2016, Donnelly Penman was engaged by MBCN through a letter agreement (the “Engagement Letter”) to provide merger advisory services. Pursuant to the Engagement Letter, Donnelly Penman received an initial advisory fee, an additional advisory fee, will receive a portion of its transaction fee at signing of the

Agreement (30%), with the remainder of its transaction fee payable at closing of the Acquisition, and in connection with the issuance of this fairness opinion will receive a fee from MBCN. Additionally, MBCN has agreed to reimburse Donnelly Penman for its out-of-pocket expenses (up to $7,500) and has agreed to indemnify Donnelly Penman and certain related persons against certain liabilities possibly incurred in connection with services performed.

Donnelly Penman has previously been engaged by MBCN within the last two years to provide advisory services. In October 2015, Donnelly Penman was engaged by MBCN in connection with an acquisition opportunity, which was not consummated, for which it received an initial retainer. Additionally, in March 2015, Donnelly Penman was engaged by MBCN in connection with an acquisition opportunity, which was not consummated, for which it received an initial retainer. Donnelly Penman has not been engaged by Liberty for any purpose.

In arriving at our opinion, we engaged in discussions with members of the management teams of MBCN and Liberty concerning the historical and current business operations, financial conditions and prospects of MBCN and Liberty, as well as engaged in discussions with independent Board Directors of MBCN, and we reviewed, among other things:

We have also held discussions with the senior management of MBCN regarding past and current business operations, regulatory relations, financial condition and future prospects of MBCN and such other matters as we have deemed relevant to our inquiry. We have also held discussions with the senior management of Liberty with regard to their business operations, regulatory relations, earnings results and future prospects. We have relied upon the management team of MBCN and Liberty as to the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefore) prepared by and provided to us by management of MBCN and Liberty and we have assumed, at the direction of MBCN and Liberty, that such forecasts and projections reflect the best currently available estimates and judgments of such management and that such forecasts and projections will be realized in the amounts and in the time periods currently estimated by such management and that they provide a reasonable basis upon which we could form our opinion. Such forecasts and projections were not prepared with the expectation of public disclosure. All such projected financial information is based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in such projected financial information. We have relied on this projected information without independent verification or analysis and do not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

In conducting our review and arriving at our opinion, we, with your consent, have relied, without independent investigation, upon the accuracy and completeness of all financial and other information provided to us by MBCN and Liberty or upon publicly available information. We do not undertake any responsibility for the accuracy, completeness or reasonableness of, or any obligation independently to verify, such information. We have further relied upon the assurance of management of MBCN and Liberty that they were unaware of any facts that would make the information provided or available to us incomplete or misleading in any respect. We did not make any independent evaluations, valuations or appraisals of the assets or liabilities of MBCN or Liberty. We did not review any individual credit files and assumed that the aggregate allowances for credit losses relating to the loans of MBCN and Liberty were and will continue to be adequate after the Acquisition to cover such losses. Our opinion is necessarily based upon economic and market conditions and other circumstances as they existed and evaluated by us on the date of this letter. We do not have any obligation to update this opinion, unless requested by you in writing to do so, and we expressly disclaim any responsibility to do so in the absence of such a written request.

No limitations were imposed by MBCN or Liberty on us or on the scope of our investigation or the procedures that were followed by us in rendering this opinion. The form and amount of the Total Consideration was determined through arms’ length negotiations between MBCN and Liberty. We were not requested to opine as to, and this opinion does not address, MBCN’s underlying business decision to proceed with or effect the Acquisition or the relative merits of the Acquisition compared to any alternative transaction that might be available to MBCN. Further, this letter does not constitute a recommendation to the shareholders of MBCN with respect to any approval of the Agreement or the Acquisition. Additionally, we were not requested to opine as to, and this opinion does not address, the fairness of the amount or nature of the compensation to any of Liberty’s officers, directors or employees.

In our analyses, we have made numerous assumptions with respect to industry performance, business and economic conditions, and other matters, many of which are beyond the control of MBCN and Liberty. The credit, financial and stock markets can experience unusual volatility and we express no opinion or view as to any potential effects of such volatility on MBCN, Liberty, or the Acquisition. No company or merger utilized in our analyses was identical to MBCN, Liberty, or the Acquisition. Accordingly, such analyses are not based solely on arithmetic calculations; rather, they involve complex considerations and judgments concerning differences in financial and operating characteristics of the relevant companies, the timing of the relevant mergers and prospective buyer interests, as well as other factors that could affect the public trading markets of companies to which MBCN is being compared. None of the analyses performed by us was assigned a greater significance than any other.

This opinion has been reviewed and approved by the Donnelly Penman Fairness Opinion Committee in conformity with our policies and procedures established under the requirement of Rule 5150 of the Financial Industry Regulatory Authority (FINRA).

Based upon and subject to the foregoing, we are of the opinion that, as of July 27, 2016, the Total Consideration to be paid by MBCN to Liberty shareholders under the Agreement is fair, from a financial point of view, to the shareholders of MBCN.

Section 1701.13(E) of the Ohio Revised Code grants corporations broad powers to indemnify directors, officers, employees and agents. Section 1701.13(E) provides:

(E)(1) A corporation may indemnify or agree to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative, other than an action by or in the right of the corporation, by reason of the fact that hethe person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against expenses, including attorney’s fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by ~~him~~the person in connection with such action, suit, or proceeding, if hethe person acted in good faith and in a manner hethe person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, if hethe person had no reasonable cause to believe ~~his~~the person’s conduct was unlawful. The termination of any action, suit, or proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, he had reasonable cause to believe that ~~his~~the person’s conduct was unlawful.

(2) A corporation may indemnify or agree to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that hethe person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against expenses, including attorney’s fees, actually and reasonably incurred by ~~him~~the person in connection with the defense or settlement of such action or suit, if hethe person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any of the following:

(a) Any claim, issue, or matter as to which such person is adjudged to be liable for negligence or misconduct in the performance of ~~his~~the person’s duty to the corporation unless, and only to the extent that, the court of common pleas or the court in which such action or suit was brought determines, upon application, that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court of common pleas or such other court shall deem proper;

(b) Any action or suit in which the only liability asserted against a director is pursuant to section 1701.95 of the Revised Code.

(3) To the extent that a director, trustee, officer, employee, member, manager, or agent has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in division (E)(1) or (2) of this section, or in defense of any claim, issue, or matter ~~therein, he~~in the action, suit, or proceeding, the person shall be indemnified against expenses, including attorney’s fees, actually and reasonably incurred by ~~him~~the person in connection with the action, suit, or proceeding.

(4) Any indemnification under division (E)(1) or (2) of this section, unless ordered by a court, shall be made by the corporation only as authorized in the specific case, upon a determination that indemnification of the director, trustee, officer, employee, member, manager, or agent is proper in the circumstances because hethe person has met

the applicable standard of conduct set forth in division (E)(1) or (2) of this section. Such determination shall be made as follows:

(a) By a majority vote of a quorum consisting of directors of the indemnifying corporation who were not and are not parties to or threatened with the action, suit, or proceeding referred to in division (E)(1) or (2) of this section;

(b) If the quorum described in division (E)(4)(a) of this section is not obtainable or if a majority vote of a quorum of disinterested directors so directs, in a written opinion by independent legal counsel other than an attorney, or a firm having associated with it an attorney, who has been retained by or who has performed services for the corporation or any person to be indemnified within the past five years;

(d) By the court of common pleas or the court in which the action, suit, or proceeding referred to in division (E)(1) or (2) of this section was brought.

Any determination made by the disinterested directors under division (E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this section shall be promptly communicated to the person who threatened or brought the action or suit by or in the right of the corporation under division (E)(2) of this section, and within ten days after receipt of such notification, ~~such~~the person shall have the right to petition the court of common pleas or the court in which ~~such~~the action or suit was brought to review the reasonableness of ~~such~~that determination.

(5) (a) Unless at the time of a director’s act or omission that is the subject of an action, suit, or proceeding referred to in division (E)(1) or (2) of this section, the articles or the regulations of a corporation state, by specific reference to this division, that the provisions of this division do not apply to the corporation and unless the only liability asserted against a director in an action, suit, or proceeding referred to in division (E)(1) or (2) of this section is pursuant to section 1701.95 of the Revised Code, expenses, including attorney’s fees, incurred by a director in defending the action, suit or proceeding shall be paid by the corporation as they are incurred, in advance of the final disposition of the action, suit, or proceeding upon receipt of an undertaking by or on behalf of the director in which hethe director agrees to do both of the following:

(i) Repay such amount if it is proved by clear and convincing evidence in a court of competent jurisdiction that ~~his~~the director’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation;

(ii) Reasonably cooperate with the corporation concerning the action, suit, or proceeding.

(b) Expenses, including attorney’s fees, incurred by a director, trustee, officer, employee, member, manager, or agent in defending any action, suit, or proceeding referred to in division (E)(1) or (2) of this section, may be paid by the corporation as they are incurred, in advance of the final disposition of the action, suit, or proceeding, as authorized by the directors in the specific case, upon receipt of an undertaking by or on behalf of the director, trustee, officer, employee, member, manager, or agent to repay such amount, if it ultimately is determined that hethe person is not entitled to be indemnified by the corporation.

(6) The indemnification or advancement of expenses authorized by this section shall not be exclusive of, and shall be in addition to, any other rights granted to those seeking indemnification or advancement of expenses, under the articles, the regulations, any agreement, a vote of shareholders or disinterested directors, or otherwise, both as to action in their official capacities and as to action in another capacity while holding their offices or positions, and shall continue as to a person who has ceased to be a director, trustee, officer, employee, member,

manager, or agent and shall inure to the benefit of the heirs, executors, and administrators of ~~such~~that person. A right to indemnification or to advancement of expenses arising under a ~~person.~~provision of the articles or the regulations shall not be eliminated or impaired by an amendment to that provision after the occurrence of the act or omission that becomes the subject of the civil, criminal, administrative, or investigative action, suit, or proceeding for which the indemnification or advancement of expenses is sought, unless the provision in effect at the time of that act or omission explicitly authorizes that elimination or impairment after the act or omission has occurred.

(7) A corporation may purchase and maintain insurance or furnish similar protection, including, but not limited to, trust funds, letters of credit, or self-insurance, on behalf of or for any person who is or was a director,

officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against any liability asserted against ~~him~~the person and incurred by ~~him~~the person in any such capacity, or arising out of ~~his~~the person’s status as such, whether or not the corporation would have the power to indemnify ~~him~~the person against ~~such~~that liability under this section. Insurance may be purchased from, or maintained with, a person in which the corporation has a financial interest.

(8) The authority of a corporation to indemnify persons pursuant to division (E)(1) or (2) of this section does not limit the payment of expenses as they are incurred, indemnification, insurance, or other protection that may be provided pursuant to divisions (E)(5),(6), and (7) of this section. Divisions (E)(1) and (2) of this section do not create any obligation to repay or return payments made by the corporation pursuant to ~~divisions~~division (E)(5),(6) or (7).

(9) As used in division (E) of this section, “corporation” includes all constituent entities in a consolidation or merger and the new or surviving corporation, so that any person who is or was a director, officer, employee, trustee, member, manager, or agent of such a constituent entity, or is or was serving at the request of such constituent entity as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, shall stand in the same position under this section with respect to the new or surviving corporation as hethe person would if hethe person had served the new or surviving corporation in the same capacity.

Middlefield Banc Corp.’s regulations contain the following provision having to do with indemnification of directors and officers:

“SECTION 1 – INDEMNIFICATION. The Corporation shall indemnify, to the full extent then permitted by law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (and including, without limitation, any action, suit or proceeding by or in the right of the Corporation or otherwise), by reason of the fact that he is or was a member of the Board of Directors or an officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The Corporation shall pay, to the full extent then required by law, expenses, including attorney’s fees, incurred by a member of the Board of Directors in defending any such action, suit or proceeding as they are incurred, in advance of the final disposition thereof, and may pay, in the same manner and to the full extent then permitted by law, such expenses incurred by any other person. The indemnification and payment of expenses provided hereby shall not be exclusive of, and shall be in addition to, any other rights

granted to those seeking indemnification under any law, the Articles, any agreement, vote of shareholders or disinterested members of the Board of Directors, or otherwise, both as to action in official capacities and as to action in another capacity while he or she is a member of the Board of Directors, or an officer, employee or agent of the Corporation, and shall continue as to a person who has ceased to be a member of the Board of Directors, trustee, officer, employee or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person.

SECTION 2 – INSURANCE. To the full extent then permitted by law and authorized by the Board of Directors, the Corporation may purchase and maintain insurance or furnish similar protection, including but not limited to trust funds, letters of credit or self-insurance, on behalf of or for any persons described in Section 1 of this article against any liability asserted against and incurred by any such person in any such capacity, or arising out of his status as such, regardless of whether the Corporation would have the power to indemnify such person against such liability. Insurance may be purchased from or maintained with a person in which the Corporation has a financial interest.

SECTION 3 – AGREEMENTS. Upon approval by the Board of Directors, the Corporation may enter into agreements with any persons whom the Corporation may indemnify under these Regulations or under law and undertake thereby to indemnify such persons and to pay the expenses incurred by them in defending any action, suit or proceeding against them, regardless of whether the Corporation would have the power under law or these Regulations to indemnify any such person.

Directors and executive officers of Middlefield Banc Corp. entered into indemnification agreements with Middlefield Banc Corp. The indemnification agreements allow the directors and officers to select the most favorable indemnification rights provided under (1) Middlefield Banc Corp.’s articles of incorporation and regulations in effect on the date of the indemnification agreement or on the date expenses are incurred, (2) state law in effect on the date of the indemnification agreement or on the date expenses are incurred, (3) any liability insurance policy in effect when a claim is made or on the date expenses are incurred, and (4) any other indemnification arrangement otherwise available. The agreements cover all fees, expenses, judgments, fines, penalties, and settlement amounts paid in any matter relating to the director’s or officer’s role as Middlefield Banc Corp.’s director, officer, employee, agent or when serving as Middlefield Banc Corp.’s representative with another entity. Each indemnification agreement provides for the prompt advancement of all expenses incurred, subject to the obligation to repay those advances if the director or officer is later determined to be not entitled to indemnification. A form of the indemnification agreement is included as Exhibit 99.1 to the Form 10 Registration Statement, Amendment No. 1, filed by Middlefield Banc Corp. on June 14, 2001 and is incorporated herein by this reference.

Middlefield Banc Corp. maintains directors’ and officers’ insurance coverage for its officers and directors.

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial~~bona fide~~ ~~offering thereof.~~

C. The undersigned Registrant hereby undertakes that prior to any public reoffering of the securities registered hereunder through use of a prospectus that is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

D.C. The Registrant undertakes that every prospectus (1) that is filed pursuant to paragraph C.B. immediately preceding, or (2) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.

E.D. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

F. The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

G.E. The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this Registration Statement Amendment No. 1 to be signed on its behalf by the undersigned, thereunto duly authorized, in the Village of Middlefield, State of Ohio, on ~~September 29,~~November 18, 2016.
