At the special meeting, we will seek stockholder approval of (i) an amendment to our Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 40,000,000 to 60,000,000 and (ii) the issuance of up to 6,000,000 shares of our common stock in exchange for outstanding trust preferred securities issued by Old Second Capital Trust I, and potentially in exchange for outstanding trust preferred securities of Old Second Capital Trust II in a separate private exchange transaction, in accordance with Nasdaq Marketplace Rule 5635.

The board of directors recommends that you vote "FOR" the proposal to amend our Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 40,000,000 to 60,000,000, "FOR" the proposal to permit us to issue up to 6,000,000 shares of our common stock in accordance with Nasdaq Marketplace Rule 5635 in exchange for outstanding trust preferred securities issued by Old Second Capital Trust I and, potentially, Old Second Capital Trust II, and "FOR" the proposal to permit the board of directors to adjourn, postpone or continue the special meeting, if necessary and appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the proposals set forth above, or if a quorum is not present at the time of the special meeting.

PROXY STATEMENT




PROXY STATEMENT

        This proxy statement is furnished in connection with the solicitation of proxies by the board of directors of Old Second Bancorp, Inc., a Delaware corporation, of proxies to be voted at the specialannual meeting of stockholders. This meeting is to be held at the main office of Old Second National Bank, 37 South River Street,Copley Theater, North Island Center, located at 8 East Galena Boulevard, Aurora, Illinois on August 2, 2010,May 17, 2011 at 11:00 a.m., local time, or at any adjournmentspostponements or postponementsadjournments of the meeting. Old Second conducts full service community banking and trust business through its wholly-owned subsidiary, Old Second National Bank (the "Bank").Bank.

        The board has fixedA copy of our annual report for the close of business on June 25,year ended December 31, 2010, as the record date for determining the stockholders entitled to notice of, and to vote at, the special meeting. On the record date, we had 13,911,692 shares of common stock, par value $1.00 per share, outstanding and entitled to vote. The approximate date on which theincludes audited financial statements, is enclosed. This proxy statement and the accompanying proxy arewas first being sentmailed to stockholders is July 2, 2010.

        The proposal to approve an amendment to our Restated Certificate of Incorporation to increase the number of authorized shares of our common stock is referred to herein as the "Common Stock Proposal"; the proposal to approve the issuance of shares of our common stock in accordance with Nasdaq Marketplace Rule 5635 in exchange for outstanding trust preferred securities of Old Second Capital Trust I, and potentially Old Second Capital Trust II, is referred to herein as the "TruPS Exchange Proposal"; and the proposal to grant the board of directors the authority to adjourn, postponeon or continue the special meeting, if necessary, to solicit additional proxies is referred to herein as the "Adjournment Proposal."

        The following information regarding the meeting and the voting process is presented in a question and answer format.about April 18, 2011.

Q.    Why am I receiving this proxy statement and proxy form?

A.

You are receiving a proxy statement and proxy form from us because on JuneMarch 25, 2010,2011, the record date for the specialannual meeting, you owned shares of our common stock. This proxy statement describes the matters that will be presented for consideration by the stockholders at the specialannual meeting. It also gives you information concerning thethese matters to assist you in making an informed decision.


Q.    What matters will be voted on at the meeting?

A.

You are being asked to vote onon: (i) the approvalelection of an amendmentthree nominees to our Restated Certificate of Incorporation to increase the number of authorized shares of our common stock from 40,000,000 to 60,000,000 shares, as well as on the approval of the issuance of additional shares of our common stock in exchange for a portion of the outstanding trust preferred securities issued by Old Second Capital Trust I, and potentially for a limited number of outstanding trust preferred securities issued by Old Second Capital Trust II in a separate private exchange transaction (subject, however, to the maximum 6,000,000 shares that we may issue pursuant to the terms of the exchange offer and the potential separate private exchange transaction, in the aggregate). Additionally, you are being asked to grant the board of directorsdirectors; (ii) a non-binding, advisory proposal on executive compensation, or "say-on-pay" proposal; (iii) the ability to adjourn, postpone or continue the special meeting to solicit additional proxies in the event that we have insufficient votes to adopt eitherratification of the other proposals, or if a quorum is not preset at the special meeting.

Q.    Why does the Company need to increase the number of authorized shares of common stock?

A.
Like a large number of financial institutions across the United States, we have been impacted by adverse economic conditions. As a result of this economic downturn and the depressed real estate markets, the Bank has experienced a decline in the performance of its loans, particularly real estate construction and development loans, which has resulted in the Company incurring a net loss of $65.6 millionPlante & Moran, PLLC as our independent registered public accounting firm for the year ended December 31, 20092011; and a net loss of $8.6 million for(iv) any other business that may properly be brought before the three-month period ended March 31, 2010. Because of the increased stress in the Bank's loan portfolio, the Bank's board of directors has agreed with the Office of the Comptroller of the Currency (the "OCC") to maintain the Bank's regulatory capital ratios at levels in excess of the general minimums required to be considered "well capitalized" under OCC regulations. Specifically, the Bank's board of directors agreed to meet by December 31, 2009, and thereafter maintain, a Tier 1 capital ratio of at least 8.75% and a total risk-based capital ratio of at least 11.25%. The Bank achieved these heightened regulatory capital ratios by December 31, 2009 and remained in compliance with them as of March 31, 2010. Nevertheless, if the Bank continues experiencing stress in its loan portfolio and, as a result, we continue incurring net losses, the Bank may be unable to maintain the heightened capital ratios that it has agreed to maintain unless we raise additional capital. Furthermore, during the financial crisis of the past several years, analysts and others have focused on additional measures of a financial institution's capital position, such as tangible common equity to tangible assets and Tier 1 common equity to risk-weighted assets, to assess the financial health and stability of the institution, which also tends to impact the institution's stock price.

Q.    Why do we need to vote on the TruPS Exchange Proposal?

A.
The contemplated exchange offer and the potential separate private exchange transaction, which involve the exchange of outstanding trust preferred securities for shares of our common stock, could result in the issuance of a number of shares of our common stock that exceeds 20% of our currently outstanding shares, and the value of the outstanding trust preferred securities we receive in exchange for each share of our common stock may be less than the greater of the book value or market value per share of our common stock. In this case, Nasdaq rules require us to seek the approval of our stockholders for the issuance of the shares of our common stock in the exchange offer and the potential separate private exchange transaction.

Q.    How do I vote?

A.

A form of proxy is enclosed for use at the meeting. If the proxy is executed and returned, it may nevertheless be revoked at any time before the meeting insofar as it has not been exercised. Stockholders attending the meeting may, on request, vote their own shares even though they have previously sent in a proxy. Unless revoked or instructions to the contrary are contained in the proxies, the shares represented by validly executed proxies will be voted at the meeting and will be voted "FOR" the Common Stock Proposal,election of the nominees for director named in this proxy statement, "FOR" the TruPS Exchange Proposalsay-on-pay proposal, and "FOR" the Adjournment Proposal.

ratification of our independent registered public accounting firm.


Q.    What does it mean if I receive more than one proxy form?

        It means that you have multiple holdings reflected in our stock transfer records and/or in accounts with stockbrokers. Please sign and returnALL proxy forms to ensure that all your shares are voted.

If I hold shares in the name of a broker, or fiduciary, who votes my shares?

A.

If you received this proxy statement from your broker, or a trustee or other fiduciary who may hold your shares, your broker trustee or fiduciary should have given you instructions for directing how theyyour broker should vote your shares. It will then be theiryour broker's responsibility to vote your shares for you in the manner you direct.

        Under the rules of various national and regional securities exchanges, brokers may generally vote on routine matters, such as ratifying the ratificationappointment of an independent auditors,registered public accounting firm, but cannot vote on non-routine matters, such as the adoption or amendment of a stock incentive plan, unless they have received voting instructions from the person for whom they are holding shares. If there is a non-routine matter presented to stockholders at thea meeting and your broker does not receive instructions from you on how to vote on that matter, your broker will return the proxy card to us, indicating that he or she does not have the authority to vote on that matter. This is generally referred to as a "broker non-vote" and may affect the outcome of the voting on those matters.


Q.    What does it mean if I receive more than one proxy form?

A.
It means that you have multiple holdings reflected in our stock transfer records and/or in accounts with stockbrokers. Please sign and returnALL proxy forms to ensure that all your shares are voted.

Q.    What if I change my mind after I return my proxy?

A.
If you hold your shares in your own name, you may revoke your proxy and change your vote at any time before the polls close at the meeting. You may do this by:

signing another proxy with a later date and returning that proxy to:

Q.    How many votes do we need to hold the specialannual meeting?

A.

A majority of the shares of common stock that arewere outstanding and entitled to vote as of the record date must be present in person or by proxy at the meeting in order to hold the meeting and conduct business. On JuneMarch 25, 2010,2011, the record date, there were 13,911,69214,034,991 shares outstanding. A majority of common stock issued and outstanding. Therefore, at least 6,955,847these shares need tomust be present in person or by proxy at the special meeting for a quorum to exist.

        We will provide youEmergency Economic Stabilization Act requires the Compensation Committee to conduct, in conjunction with a copysenior risk officer of the Company, a review of the incentive compensation arrangements in place between the Company and its employees.

        The Compensation Committee certifies that, at least once every six months during the year ended December 31, 2010 (a) it has reviewed with the senior risk officer of Old Second the senior executive officer ("SEO") compensation plans and has made all reasonable efforts to ensure that these plans do not encourage SEOs to take unnecessary and excessive risks that threaten the value of Old Second; (b) it has reviewed with the senior risk officer the employee compensation plans and has made reasonable efforts to limit any unnecessary risks these plans pose to Old Second; and, (c) it has reviewed the employee compensation plans to eliminate any features of these plans that would encourage the manipulation of reported earnings of Old Second to enhance the compensation of any information that we incorporate by reference into this proxy statement, at no cost, by writing or calling us. Requests for such materials should be directedemployee ((a), (b) and (c) being collectively referred to as the "TARP Risk Assessment").

        In the course of conducting its TARP Risk Assessment, the Compensation Committee considered the overall business and risk environment confronting Old Second Bancorp, Inc.
Attention: Corporate Secretary
37 South River Street
Aurora, Illinois 60506
Telephone number: (630) 906-5480and how the SEO compensation plans and employee compensation plans serve to motivate employee behavior when operating within that environment. In particular, the Compensation Committee's TARP Risk Assessment focused on the following compensation plans (* denotes plans in which SEOs participate):

•       Amended and Restated Voluntary Deferred Compensation Plan for Executives*

 By order

•       Loan Administration Plan

•       Base Salary*

•       Officers Incentive Plan*

•       Commercial Interest Rate Swap Plan

•       Residential Lending Commission Plan

•       Compensation and Benefits Assurance Agreements*

•       Residential Lending Override Plan

•       Customer Service/Support Center Plan

•       Retail Banking Plan

•       Employees 401(k) Savings Plan and Trust*

•       Special Recognition Awards Program

•       2008 Equity Incentive Plan*

•       Wealth Management Commission Plan

        With the exception of individual bonus goals designated under the Officers Incentive Plan, Old Second does not maintain any compensation plans in which only SEOs participate. For purposes of this discussion, references to "SEO compensation plans" mean the portion of an employee plan in which the SEOs participate.

        With respect to the SEO compensation plans, the Compensation Committee believes that such plans do not encourage Old Second's SEOs to take unnecessary or excessive risks that could harm the value of the company. The Compensation Committee believes this to be true because, as is more fully described in the Compensation Discussion and Analysis, the Compensation Committee strives to provide a balanced aggregate compensation package to our SEOs that serves to incentivize our SEOs to manage the business of Old Second in a way that will result in company-wide financial success and value growth for our shareholders.


        We believe it is appropriate for our executives to focus certain of their efforts on near-term goals that have importance to the company; however, we also acknowledge that near-term focus should not be to the detriment of a focus on the long-term health and success of Old Second. In practice, providing base salary to any employee provides the most immediate reward for job performance. The Compensation Committee engages in an annual process, as is described in the Compensation Discussion and Analysis, to set base salary. We believe our process for establishing base salary is relatively free from risk to the company, as we do not typically make significant adjustments to base salary based on a single year's performance. The committee believes it is appropriate to reward our executives' focus on near-term goals, when such goals correspond to the overall company or operating division goals and direction set by our board of directors. To reward the executives for such focus, the Compensation Committee maintains an annual cash incentive plan (i.e., Officers Incentive Plan) for our executives. In establishing our annual cash incentive plan, we try to provide an adequate level of incentive for the achievement of company, operating division and individual goals, while also limiting the maximum amount that may be earned so that executives do not feel the need to strive for attainment of unreasonable or unrealistic levels of performance. In this way, we believe the design of the annual cash incentive plan does not encourage our executives to take unnecessary or excessive risks that could harm the value of Old Second.

        The other incentive compensation elements offered to our SEOs, with the exception of perquisites, are intended to reward performance over the long-term or are intended to focus our executives' attention on the long-term performance of the company. We feel there is little, if any, risk associated with our Employees 401(k) Savings Plan and Trust as it is a tax-qualified retirement plan that is subject to and maintained in accordance with the mandates of the Internal Revenue Code and the Employee Retirement Income Security Act. We believe our 2008 Equity Incentive Plan helps to tie our executives' interest more closely to those of our shareholders by giving them an equity interest in the company. We feel this equity interest in Old Second promotes a long-term focus among our executives on the financial success of the company. Finally, the Compensation Committee believes the deferred compensation arrangements (i.e., Amended and Restated Voluntary Deferred Compensation Plan for Executives, Compensation and Benefits Assurance Agreements) in place with respect to our SEOs encourage our executives to consider the long-term health of the company because, pursuant to the rules under the Internal Revenue Code and applicable guidance, those arrangements must be unfunded, unsecured promises to pay a benefit in the future. In the case of insolvency of the company, the executives participating in those arrangements would be treated as general unsecured creditors of Old Second, thus encouraging the executives to ensure a healthy organization remains after their tenure concluded.

        With respect to the employee compensation plans, the TARP Risk Assessment has not resulted in a determination by the Compensation Committee that changes were necessary to bring such plans into compliance with the TARP rules. We believe the Company has adequate policies and procedures in place to balance and control any risk-taking that may be incentivized by the employee compensation plans. The committee further believes that such policies and procedures will work to limit the risk that any employee would manipulate reporting earnings in an effort to enhance his or her compensation.


        The committee intends to continue, in accordance with its obligations under TARP, to periodically review and assess the SEO compensation plans and employee compensation plans to ensure that the risk-taking behavior incentivized by such plans is kept to an appropriate level. The committee will, as necessary, amend or discontinue any plan or revise any company policy or procedure to meet its obligations under TARP.

The amounts represent possible payments pursuant to our bonus plan for 2010 performance. The plan is described in the Compensation Discussion and Analysis section.

Additional shares of restricted stock were awarded in February 2011 as follows: Mr. Skoglund 35,330 shares, Mr. Cheatham 35,330 shares, and Mr. Eccher 35,330 shares. Because these shares were awarded in 2011, they are not reflected in this table.

Effective January 14, 2011, Mr. Sloan resigned as Executive Vice President and Chief Risk Officer of Old Second.

        As described in the Compensation and Discussion Analysis section, we sponsor an executive deferred compensation plan, which is a means by which certain executives may voluntarily defer all or a portion of their salary and/or bonus without regard to the statutory limitations under tax qualified plans. The plan is funded by participant deferrals, company matching contributions and discretionary employer profit sharing contributions. Participants may invest their deferrals and the company contributions, if made, to the plan on their behalf in a mutual fund-like investment pool managed by an independent third party. Participants may elect to receive their plan balance in a lump sum or in up to 20 annual installments following retirement. Participants are not permitted to make a withdrawal from the plan during their employment, except in the event of hardship as approved by the plan's administrator.

Potential Payments Upon Termination or Change in Control

        The TARP rules will prohibit Old Second from making "any payment" to the named executive officers "for departure from the company for any reason, except for payments for services performed or benefits accrued." Except in the case of an officer's death or disability, the TARP rules will generally prohibit the payment of any severance amounts and will also serve to restrict the ability of Old Second to accelerate the vesting of any compensation and/or benefits upon a termination of employment or a change in control.

        The committee believes that, even though the TARP rules will prohibit such payments if a change in control or other termination of employment occurs during the TARP period, it is beneficial to understand the terms of the arrangements that would apply except for such TARP rules. Each of Mssrs. Skoglund, Cheatham, Eccher and Sloan entered into Compensation and Benefits Assurance Agreements with Old Second (each, an "Assurance Agreement"), which provide for payments and benefits to a terminating executive following a change in control of Old Second. In addition, our Cash Incentive Plan provides for termination related benefits. Other than the benefits provided by the Assurance Agreements and pursuant to the Cash Incentive Plan, none of our named executive officers will be entitled to any payments or benefits as a result of the occurrence of a change in control or as a result of a termination of employment in connection with a change in control. As noted above, effective January 14, 2011, Mr. Sloan resigned as Executive Vice President and Chief Risk Officer of Old Second. He did not receive any benefits pursuant to his Assurance Agreement as a result of his resignation.


        Assurance Agreements.    Other than as is provided in the Assurance Agreements, and except as is provided in accordance with the terms of our equity incentive plan and our cash incentive plan for executive officers, no named executive officer will be entitled to any payments or benefits as a result of the occurrence of a change in control or as a result of a termination of employment in connection with a change in control. The Assurance Agreements have an initial term of one-year and, unless earlier terminated by either party, will automatically renew for successive one-year periods. Upon the occurrence of a change in control, the terms of the Assurance Agreements shall automatically renew for a two-year period (three-year period, in the case of Mr. Skoglund) and terminate following such extended period. The Assurance Agreements provide that, in the case of: (i) a termination of employment by the company without "cause" within six months prior to, or 24 months (36 months, in the case of Mr. Skoglund) immediately following, a change in control, (ii) a termination of employment by an executive for "good reason" within 24 months (36 months, in the case of Mr. Skoglund) following a change in control, or (iii) a material breach by Old Second (or any successor) of a provision of the Assurance Agreement, an executive officer will be entitled to:

        In exchange for the payments and benefits provided under the Assurance Agreements, the executive officers agree to be bound by a 24 month (36 month, in the case of Mr. Skoglund) restrictive


covenant. The restrictive covenant will prohibit the executive officers from using, attempting to use, disclosing or otherwise making known to any person or entity (other than Old Second's board of directors) confidential or proprietary knowledge or information which the executive officers may acquire in the course of their employment.

        The Assurance Agreements define certain relevant terms, generally, as follows:

        In exchange for the payments and benefits provided under the Assurance Agreements, the executive officers agree to be bound by confidentiality, non-competition and non-disclosure provisions.

        Except for payments and benefits provided by the Assurance Agreements, all other payments and benefits provided to any NEO upon termination of his or her employment are the same as the payments and benefits provided to other eligible employees of Old Second.

        The TARP rules do not prohibit payments made to a named executive officer (or his estate) where the officer's employment terminates as a result of his death or disability. Our Cash Incentive Plan provides for the payment of a pro rata cash bonus to be paid in the case of death or disability. Since no cash bonus was paid for 2010, there would have been no pro rata bonus as of December 31, 2010.

        Retirement, Death and Disability.    Generally speaking, a termination of employment due to retirement, death or disability does not entitle the named executive officers to any payments or benefits



that are not available to other employees. Following a termination due to death or disability, an employee (or his or her estate) shall be entitled to the following:

        Also, it should be noted that, pursuant to existing agreements, as of the time of a termination of employment due to retirement, all unvested stock options shall become immediately 100% vested; however, this acceleration of vesting will not be true in the case of a retirement during the TARP period.

        Acceleration of Vesting Upon a Change in Control.    All employees, including the named executive officers, who receive stock options or restricted stock under our equity incentive plan will immediately vest in any unvested stock options and restricted stock held by such employees upon the occurrence of a change in control. Note, however, that this acceleration of vesting will not be true in the case of a retirement during the TARP period.



DIRECTOR COMPENSATION

        Each director of Old Second also serves as a director of Old Second National Bank. In 2009 and 2010, non-employee directors received $1,000 for every board meeting and $500 for every committee meeting attended if there were no other bank-level meetings held that day. Non-employee directors of Old Second National Bank received a $13,000 annual retainer. Due to increased responsibilities associated with mandates from Sarbanes-Oxley, the Lead Director and Compensation Committee Chairman, Mr. Palmer, received an $18,000 retainer in 2010 and the Audit Committee Chairman, Mr. Finn, received a $20,000 annual retainer in 2010, due to increased meetings and increased time spent on behalf of the Audit Committee. From 2005-2009, we annually awarded each non-employee director of Old Second Bancorp options to purchase 1,500 shares of our common stock, for a total of 7,500 in options. No additional options were granted in 2010. Additionally, in February 2009, we awarded 596 restricted stock units to each non-employee director and in January 2010, we awarded 1,200 restricted stock units to each non-employee director. Mr. Skoglund, the President and Chief Executive Officer of Old Second did not receive any board fees for his service on the holding company board, nor did he receive board fees for his service on the board of the Old Second National Bank. The following table sets forth the fees earned by each non-employee director and senior director in 2010:

We maintain the Old Second Bancorp Directors Fee Deferral Plan, under which directors are permitted to defer receipt of their directors' fees and earn a rate of return based upon the performance of our stock. We may, but are not required to, contribute the deferred fees into a trust, which may hold our stock. The plan is a nonqualified deferred compensation plan and the directors have no interest in the trust. The deferred fees and any earnings thereon are unsecured obligations of Old Second. Any shares held in the trust are treated as treasury shares and may not be voted on any matter presented to stockholders. We do not pay any above-market interest on the compensation or fees deferred by the directors.

The amounts represent the grant date fair value for restricted stock awards in accordance with ASC 718—"Compensation—Stock Compensation" for each year in which options were granted. A discussion of the assumptions used in calculating the values may be found in our 2010 audited financial statements included in our annual report to stockholders.

Compensation Committee Interlocks and Insider Participation

        During 2010, the members of the Compensation Committee were Messrs. Fagel, Kane, Meyer and Palmer. None of these individuals was an officer or employee of Old Second or its subsidiaries in 2010, and none of these individuals is a former officer or employee of either organization. In addition, during 2010, no executive officer served on the board of directors or compensation committee of any other corporation with respect to which any member of our Compensation Committee was engaged as an executive officer.

Transactions with Management

        Our directors and executive officers and their associates were customers of, and had transactions with, Old Second and our subsidiaries in the ordinary course of business during 2010. Additional transactions may be expected to take place in the future. All outstanding loans, commitments to loan, transactions in repurchase agreements, certificates of deposit and depository relationships, in the opinion of management, were in the ordinary course of business and were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the lender. All such loans are approved by the subsidiary bank's board of directors in accordance with the bank regulatory requirements. Additionally, the Audit Committee considers other non-lending transactions between a director and Old Second, including its subsidiaries, to ensure that such transactions do not affect a director's independence.

        Edward Bonifas, one of our directors, is the Vice President of Alarm Detection Systems, Inc., a firm providing electronic security and monitoring services to Old Second. In 2010, Old Second was billed $256,789.00 for the services provided by Alarm Detection Systems. Pursuant to its policies on such related-party transactions, the Audit Committee has reviewed and approved Old Second's transactions with Alarm Detection Systems, and the board has further determined that such transactions do not affect Mr. Bonifas's status as an independent director pursuant to the rules of the NASDAQ Stock Market.



PROPOSAL 2:

ADVISORY (NON-BINDING) VOTE ON EXECUTIVE COMPENSATION

        Section 14A of the Securities Exchange Act of 1934, as created by Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), and the rules and regulations promulgated thereunder, require publicly traded companies, such as Old Second, to conduct a separate stockholder advisory vote to approve the compensation of certain executive officers, as disclosed pursuant to the Securities and Exchange Commission's compensation disclosure rules, commonly referred to as a "say-on-pay" vote. In addition, the American Recovery and Reinvestment Act of 2009 ("ARRA") includes a provision requiring participants in the TARP Capital Purchase Program, such as Old Second, to provide such say-on-pay votes so long as any obligation arising under the program remains outstanding.

        Section 14A and the rules promulgated thereunder also require public companies to provide a separate stockholder vote regarding the frequency with which such say-on-pay votes should occur: every year, every two years, or every three years. However, companies subject to ARRA, such as Old Second, are required to provide a say-on-pay vote at any annual meeting of stockholders for which proxies are solicited for the election of directors (or a special meeting in lieu of such annual meeting), and are therefore exempt from the requirement to provide stockholders with a frequency vote for so long as they remain subject to ARRA.

        In accordance with these requirements, we are providing stockholders with an advisory vote on the compensation of our executive officers, but no vote regarding the frequency of future such say-on-pay votes is required at this time.

        As described in more detail in the Compensation Discussion and Analysis section of this proxy statement, the overall objectives of Old Second's compensation programs have been to align executive officer compensation with the success of meeting long-term strategic operating and financial goals. Stockholders are urged to read the Compensation Discussion and Analysis section of this proxy statement, as well as the Summary Compensation Table and other related compensation tables and narrative disclosure that describe the compensation of our named executive officers in 2010. The Compensation Committee and the board of directors believe that the policies and procedures articulated in the Compensation Discussion and Analysis section are effective in implementing our compensation philosophy and achieving its goals, and that the compensation of our executive officers in fiscal 2010 reflects and supports these compensation policies and procedures.

        The following resolution is submitted for stockholder approval:

        "RESOLVED, that Old Second Bancorp, Inc.'s stockholders approve, on an advisory basis, its executive compensation as described in the section captioned 'Compensation Discussion and Analysis' and the tabular disclosure regarding named executive officer compensation under 'Executive Compensation' contained in the Company's proxy statement dated April 18, 2011."

        Approval of this resolution requires the affirmative vote of holders of a majority of the shares of stock having voting power and present in person or represented by proxy at the annual meeting. While this say-on-pay vote is required, as provided in both the ARRA and Section 14A of the Securities Exchange Act, it is not binding on our board of directors and may not be construed as overruling any decision by the board. However, the Compensation Committee will take into account the outcome of the vote when considering future compensation arrangements.

The board of directors recommends stockholders vote to approve the overall compensation of our named executive officers by voting "FOR" this proposal. Proxies properly signed and returned will be voted "FOR" this proposal unless stockholders specify otherwise.



PROPOSAL 3:

RATIFICATION OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

General

        Stockholders are also being asked to adopt a resolution to ratify the appointment of Plante & Moran, PLLC as our independent registered public accounting firm for the year ending December 31, 2011. If the stockholders do not ratify the selection of Plante & Moran, PLLC at the annual meeting, the Audit Committee will consider selecting another firm of independent public accountants. Representatives from Plante & Moran, PLLC are expected to be present at the annual meeting and will have an opportunity to make a statement, if they so desire, as well as to respond to appropriate questions that may be asked by stockholders.

Board Recommendation

        The board of directors recommends that you vote your shares "FOR" the ratification of Plante & Moran, PLLC as our independent registered public accounting firm for the year ending December 31, 2011.

Change in Principal Accountants

        Grant Thornton LLP served as our independent registered public accounting firm from 2006 through the completion of the audit of our fiscal year 2009 financial statements, auditing our financial statements and the report on such financial statements appearing in our Annual Report on Form 10-K for each fiscal year ending during that period. During 2009, the Audit Committee sought competitive proposals for audit services from a group of independent registered public accounting firms and the process resulted in a change in our independent registered public accounting firm for 2010 to Plante & Moran.

        Grant Thornton's reports on our consolidated financial statements for fiscal years ending December 31, 2008 and 2009 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the 2009 and 2008 fiscal years, and through the date of Grant Thornton's dismissed as our independent registered public accounting firm, there were no reportable events described in Item 304(a)(1)(v) of Regulation S-K, as promulgated by the Securities and Exchange Commission. Additionally, there were no disagreements with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Grant Thornton, would have caused Grant Thornton to make reference thereto in its reports on our financial statements for such years.

        We provided Grant Thornton with a copy of the foregoing disclosures set forth above and requested that Grant Thornton review such disclosures and furnish a letter addressed to the Securities and Exchange Commission stating whether or not Grant Thornton agrees with such statements. The response letter from Grant Thornton was attached as an Exhibit to the Form 8-K filed on March 8, 2010.

        During the fiscal years ended December 31, 2008 and 2009, we did not consult Plante & Moran, PLLC with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, or regarding any other matters or reportable events described under Item 304(a)(2) of Regulation S-K.


Accountant Fees

        Audit Fees.    The aggregate fees and expenses billed by Plante & Moran PLLC in connection with the audit of our annual financial statements and the related securities filings were $256,282 for 2010. The aggregate fees and expenses billed by Grant Thornton LLP in connection with the audit of our annual financial statements and the required securities filings were $343,000 for 2009.

        Audit Related Fees.    Audit related fees billed by Plante & Moran PLLC for 2010 were $14,500 and audit related fees billed by Grant Thornton LLP for 2009 were $27,300.

        Tax Fees.    There were no amounts for tax related services billed by Plante & Moran, PLLC for 2010 or by Grant Thornton LLP for 2009.

        All Other Fees.    There were no aggregate fees or pre-approved expenses billed by Plante & Moran, PLLC or Grant Thornton LLP for all other services rendered to us during the years ended December 31, 2010 and 2009.

        The Audit Committee is solely responsible for the pre-approval of all audit and non-audit services to be provided by the independent accountants and the committee exercises its authority to do so in accordance with a policy that it has adopted. All services provided by Plante & Moran, PLLC or Grant Thornton LLP were approved pursuant to the pre-approval policy. The pre-approval policy is available on our website at www.oldsecond.com.



AUDIT COMMITTEE REPORT

        The Audit Committee assists the board in carrying out its oversight responsibilities for our financial reporting process, audit process and internal controls. The Audit Committee also reviews the audited financial statements and recommends to the board that they be included in our annual report on Form 10-K. The committee is comprised solely of directors who are independent under the rules of the Nasdaq Stock Market.

        The Audit Committee has reviewed and discussed our audited financial statements for the fiscal year ended December 31, 2010 with our management and Plante & Moran, PLLC, the independent registered public accounting firm that audited our financial statements for that period. The committee has discussed with Plante & Moran, PLLC the matters required to be discussed by SAS 114 (The Auditor's Communication With Those Charged With Governance) and received and discussed the written disclosures and the letter from Plante & Moran, PLLC required by Public Company Accounting Oversight Board Rule 3526 (Communication with Audit Committees Concerning Independence). Based on the review and discussions with management and Plante & Moran, PLLC, the committee has recommended to the board that the audited financial statements be included in our annual report on Form 10-K for the fiscal year ending December 31, 2010 for filing with the Securities and Exchange Commission.

        The unaudited pro forma financial information is presented for illustrative purposes only and does not necessarily indicate the financial position or results of operations that would have been realized had the Exchange Offer been completed as of the dates indicated or that will be realized in the future if the Exchange Offer is consummated. The selected unaudited pro forma financial information has been derived from, and should be read in conjunction with, our historical consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 and our Quarterly Report on Form 10-Q for the three-month period ended March 31, 2010 filed with the SEC, each of which is incorporated by reference into this proxy statement.

        Our unaudited pro forma consolidated balance sheets as of March 31, 2010 have been presented as if the Exchange Offer had been completed on March 31, 2010 and our pro forma consolidated statements of income have been presented as if the Exchange Offer had been completed on January 1, 2009.

        For purposes of the pro forma presentations for the year ended December 31, 2009 and the period ended and as of March 31, 2010, we have assumed that, for purposes of the Exchange Offer, the volume weighted average price of our common shares is $3.7989, which we determined assuming the pricing date for the determination of such price ended on and included June 18, 2010. We have also assumed that our stockholders will approve the TruPS Exchange Proposal such that we will not be limited in the number of shares that we may issue in the Exchange Offer to 2,750,000.

        We have shown the pro forma impact of a "High Participation Scenario" and a "Low Participation Scenario" with respect to the Exchange Offer. The High Participation Scenario assumes the tender of 75% of the trust preferred securities and exchange of such securities for shares of our common stock. The Low Participation Scenario assumes the tender of 25% of the trust preferred securities and exchange of such securities for shares of our common stock. We assumed participation rates of 75% and 25% for the High Participation Scenario and Low Participation Scenario, respectively, based on the results of concluded similar exchange offers by similarly situated issuers. The inclusion of the Exchange Offer in the pro forma financial information does not necessarily indicate that such transaction is likely to occur.

        We have further assumed that the Exchange Offer will occur on the terms announced on June 22, 2010, including the term limiting the aggregate number of shares that may be issued in the Exchange Offer to 6,000,000.

        There can be no assurances that the foregoing assumptions will be realized in the future, including as to the amounts of trust preferred securities that will be tendered in the Exchange Offer.

Non-GAAP Financial Measures

        We and investors often use the ratio of tangible common equity to tangible assets and the ratio of Tier 1 common equity to risk-weighted assets to assess capital and the quality of capital. In addition, our banking regulators use Tier l leverage ratio, Tier 1 capital to risk-weighted assets and total capital to risk-weighted assets to assess capital adequacy and safety and soundness. The foregoing ratios are not GAAP measures and, in the case of tangible common equity to tangible assets and Tier 1 common equity to risk-weighted assets, are not necessarily comparable to similar capital measures that may be presented by other companies.

        The limitations associated with these measures are the risks that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These disclosures should not be considered an alternative to GAAP. The information provided reconciles GAAP measures and the ratios of Tier 1 capital, total capital, tangible common equity or Tier 1 common equity, as applicable, to average total assets, risk-weighted assets or tangible assets, as applicable.
