Under current New York Stock Exchange (“NYSE”) rules, which govern NYSE brokerage members, the proposal to ratify the appointment of independent auditors (Proposal 3)7) is considered a “discretionary” item. This means that brokerage firms may vote in their discretion on this matter on behalf of clients who have not furnished voting instructions in accordance with NYSE rules. In contrast, the proposals with respect to the election of directors (Proposal 1), the Director Election Charter Amendment (Proposal 2), the Uncertificated Shares Charter Amendment (Proposal 3), the Bylaws Amendment (Proposal 4), the CNB Financial Corporation 2019 Omnibus Incentive Plan (Proposal 5) and“say-on-pay” (Proposal 2)6), are“non-discretionary” items. This means brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals. Theseso-called “brokernon-votes” will not be considered in determining the number of votes necessary for approval and, therefore, will have no effect on the outcome of the vote for these proposals.

PROPOSAL 2. DIRECTOR ELECTION CHARTER AMENDMENT

We are asking our shareholders to amend our Articles of Incorporation to specify the voting standard to be used in the election of directors to the Board.

Our Articles of Incorporation do not provide a voting standard to be used in the election of directors to the Board. Pursuant to Article IV,
Section 4.02(b) of our Bylaws, directors are elected by the shareholders. In elections for directors, voting is by ballot and, if a quorum is present, directors are elected by a “majority of votes cast.” For the purposes of this Section 4.02(b), a “majority of votes cast” means that the number of shares voted “for” a director exceeds the number of votes cast “against” that director. In the event of a contested election, directors are elected by a plurality of the votes cast. A contested election occurs if, as determined by the Board, the number of nominees exceeds the number of directors to be elected.

Section 1758(b) of the Pennsylvania Business Corporation Law (the “BCL”), however, provides that directors are elected by a plurality of the votes cast. To the extent a corporation’s articles of incorporation are inconsistent with the BCL, the articles of incorporation supersede. As such, we believe that amending our Articles of Incorporation to provide that directors will be elected by a “majority of votes cast” in an uncontested election and a plurality of votes cast in a contested election will eliminate any confusion between our Bylaws and the BCL.

After careful consideration, we believe that such action is in our best interests and in the best interests of our shareholders. The new Article 10 of our Articles of Incorporation will provide that directors are elected by a “majority of votes cast” in an uncontested election and a plurality of votes cast in a contested election. A copy of the proposed amendment to our Articles of Incorporation is attached as Appendix A to this Proxy Statement and incorporated by reference into this proposal.

Vote Required

The affirmative vote of a majority of the votes cast by all shareholders entitled to vote on this proposal is required to approve this proposal. For purposes of the vote on this proposal, abstentions and other shares not voted (whether by brokernon-vote or otherwise) will not be counted as votes cast and will have no effect on the result of the vote.

Our Recommendation

The Board unanimously recommends that shareholders vote FOR the proposal.

PROPOSAL 3. UNCERTIFICATED SHARES CHARTER AMENDMENT

We are asking our shareholders to amend our Articles of Incorporation to authorize the issuance of uncertificated shares of any or all classes and series of the Corporation’s shares.

Our Articles of Incorporation are silent as to whether the Corporation’s shares must be certificated. Section 1538(f) of the BCL permits any or all classes and series of a corporation’s shares to be uncertificated if the corporation expressly so provides in its articles of incorporation. We believe that amending our Articles of Incorporation to provide for the issuance of uncertificated shares of common stock will be more cost effective for the Corporation and more convenient for our shareholders.

We believe that such action is in our best interests and in the best interests of our shareholders. The new Article 11 of our Articles of Incorporation will provide for the issuance of uncertificated shares of any or all classes and series of the Corporation’s shares. A copy of the proposed amendment to our Articles of Incorporation is attached as Appendix B to this Proxy Statement and incorporated by reference into this proposal.

Vote Required

The affirmative vote of a majority of the votes cast by all shareholders entitled to vote on this proposal is required to approve this proposal. For purposes of the vote on this proposal, abstentions and other shares not voted (whether by brokernon-vote or otherwise) will not be counted as votes cast and will have no effect on the result of the vote.

Our Recommendation

The Board unanimously recommends that shareholders vote FOR the proposal.

PROPOSAL 4. BYLAWS AMENDMENT

We are asking our shareholders to amend our Bylaws to decrease the percentage of shareholders required to call a special meeting of the shareholders from 50% to 20%.

Pursuant to Article III, Section 3.03(a) of our Bylaws, special meetings of the shareholders may be called at any time (1) by the president of the Corporation or by order of the Board; or (2) upon the written request of shareholders entitled to cast at least 50% of the votes that all shareholders are entitled to cast at the particular meeting. Section 1755(b) of the BCL, however, provides that special meetings of the shareholders may be called at any time, unless otherwise provided in the corporation’s articles of incorporation, by shareholders entitled to cast at least 20% of the votes that all shareholders are entitled to cast at the particular meeting. We believe that amending our Bylaws to lower the percentage of shareholders required to call a special meeting of the shareholders will eliminate any confusion between the Bylaws and the BCL.

After careful review, we believe that such action is in our best interests and in the best interests of our shareholders. If approved by the shareholders, Article III, Section 3.03(a) of the Bylaw will provide that special meetings of the shareholders may be called at any time (1) by the president of the Corporation or by order of the Board; or (2) upon the written request of shareholders entitled to cast at least 20% of the votes that all shareholders are entitled to cast at the particular meeting. A copy of the proposed amendment to our Bylaws is attached as Appendix C to this Proxy Statement and incorporated by reference into this proposal.

Vote Required

The affirmative vote of a majority of the votes cast by all shareholders entitled to vote on this proposal is required to approve this proposal. For purposes of the vote on this proposal, abstentions and other shares not voted (whether by brokernon-vote or otherwise) will not be counted as votes cast and will have no effect on the result of the vote.

Our Recommendation

The Board unanimously recommends that shareholders vote FOR the proposal.

PROPOSAL 5. APPROVAL OF THE CNB FINANCIAL CORPORATION 2019 OMNIBUS INCENTIVE PLAN

We are asking our shareholders to consider and to approve adoption of the CNB Financial Corporation 2019 Omnibus Incentive Plan (the “2019 Plan”).

Upon recommendation of the Executive Compensation Committee of the Board (the “ECC”), the Corporation’s Board adopted the 2019 Plan on February 12, 2019, subject to and effective upon approval by the shareholders at the Annual Meeting. The Board believes that the 2019 Plan is important to our continued growth and success and that approval of the 2019 Plan is required for us to be able to continue to make equity awards to key persons in a size that the Board believes is necessary to accomplish our goals. The purpose of the 2019 Plan is to (i) provide eligible individuals with an incentive to contribute to the success of the Corporation and to operate and manage the Corporation’s business in a manner that will provide for the Corporation’s long-term growth and profitability and that will benefit its shareholders and other important stakeholders, including its employees and customers, and (ii) provide a means of recruiting, rewarding, and retaining key personnel. To this end, the 2019 Plan provides for the grant of options, stock appreciation rights (“SARs”), restricted stock, restricted stock units (“RSUs”), deferred stock units, unrestricted stock, dividend equivalent rights, other equity-based awards, and cash bonus awards.

If our shareholders approve the 2019 Plan, the 2019 Plan will become effective on the date of the Annual Meeting, and the 2019 Plan will replace the CNB Financial Corporation 2009 Stock Incentive Plan (the “2009 Stock Incentive Plan”) as the means by which the Corporation makes equity awards to key persons. The 2009 Stock Incentive Plan automatically terminated in accordance with its terms on February 10, 2019.

If our shareholders do not approve the 2019 Plan, the 2019 Plan will not become effective, and we will no longer have an equity incentive plan under which to make equity awards to key persons. The Board believes that, if the 2019 Plan is not approved, our ability to align the interests of key persons with our shareholders through equity-based compensation would be compromised, disrupting our compensation program and impairing our ability to recruit, retain, and reward key people, or requiring us to shift our compensation plan to include more cash compensation.

Notable Features of the 2019 Plan

As described in more detail below, certain notable features of the 2019 Plan include:

Summary of the Material Terms of the 2019 Plan

A summary of the material terms of the 2019 Plan is set forth below. This summary is qualified in its entirety by the detailed provisions of the 2019 Plan, a copy of which is attached as Appendix D to this Proxy Statement and which is incorporated by reference into this proposal. We encourage shareholders to read and refer to the complete plan document in Appendix D for a more complete description of the 2019 Plan.

Effective Date; Term. If approved by our shareholders at the Annual Meeting, the 2019 Plan will become effective as of the date of the Annual Meeting (the “Effective Date”), and unless terminated sooner in accordance with the terms of the 2019 Plan or extended with shareholder approval, the 2019 Plan will terminate on the day before the tenth anniversary of the Effective Date, April 15, 2029.

Administration of the 2019 Plan. The 2019 Plan generally will be administered by a committee, which we refer to as the “Committee,” consisting of two or more directors of the Corporation. Each such director will be required to qualify as a“non-employee director” within the meaning of Rule16b-3 under the Exchange Act, and for so long as our common stock is listed on the NASDAQ, an “independent director” under the NASDAQ listing rules. The Committee initially will be the ECC and may be a subcommittee of the ECC that satisfies the foregoing requirements.

The Board will also be authorized to appoint one or more committees of the Board consisting of one or more directors of the Corporation who need not satisfy the requirements for membership above for certain limited purposes permitted by the 2019 Plan, and to the extent permitted by applicable law, the Committee will be authorized to delegate authority to the President and Chief Executive Officer of the Corporation and/or any other officers of the Corporation for certain limited purposes permitted by the 2019 Plan. The Board will retain the authority under the 2019 Plan to exercise any or all of the powers and authorities related to the administration and implementation of the 2019 Plan. References below to the Committee include a reference to the Board or another committee appointed by the Board for those periods in which the Board or such other committee appointed by the Board is acting.

Except where the authority to act on such matters is specifically reserved to the Board under the 2019 Plan or applicable law, the Committee will have full power and authority to interpret and construe all provisions of the 2019 Plan, any award, and any award agreement, and take all actions and to make all determinations required or provided for under the 2019 Plan, any award, and any award agreement, including the authority to:

Types of Awards. The 2019 Plan provides for the grant of options, SARs, restricted stock, RSUs, deferred stock units, unrestricted stock, dividend equivalent rights, other equity-based awards, and cash bonus awards.

Eligibility. All of our employees and the employees of our “subsidiaries” and “affiliates” (as defined in the 2019 Plan) are eligible to receive awards under the 2019 Plan. In addition, ournon-employee directors and consultants and advisors who perform services for us and our subsidiaries and affiliates may receive awards under the 2019 Plan, other than incentive stock options. As of February 28, 2019, there were 5 named executive officers, 9non-employee directors, and approximately 556 employees of the Corporation and its subsidiaries who would be eligible to participate in the 2019 Plan.

Shares Reserved for Issuance. The maximum number of shares of common stock that may be issued under the 2019 Plan (the “Share Limit”) will be equal to the sum of (i) 300,000 shares of our common stock, plus (ii) the number of shares of our common stock available for future awards under the 2009 Stock Incentive Plan as of the Effective Date, plus (iii) the number of shares of our common stock related to awards outstanding under the 2009 Stock Incentive Plan as of the Effective Date that thereafter terminate by expiration or forfeiture, cancellation, or otherwise without the issuance of such shares of our common stock. The maximum number of shares of our common stock available for issuance pursuant to incentive stock options granted under the Plan will be the same as the number of shares of our common stock reserved for issuance under the 2019 Plan. The shares of our common stock that are issued under the 2019 Plan may be authorized and unissued shares of our common stock, treasury shares, or any combination of the foregoing.

Share Usage. Shares of our common stock that are subject to awards, including shares of stock acquired through dividend reinvestment, will be counted against the share limit as one share for every one share subject to the award. The number of shares subject to any SARs awarded under the 2019 Plan will be counted against the share limit regardless of the number of shares actually issued to settle the SARs upon exercise. The maximum number of shares issuable under a performance-based award will be counted against the share limit as of the grant date, but such number will be adjusted to equal the actual number of shares issued upon settlement of the performance-based award to the extent different from such number of shares. If any awards terminate, expire, or are canceled, forfeited, exchanged, or surrendered without having been exercised or paid or if any awards are forfeited or expire or otherwise terminate without the delivery of any shares of our common stock or are settled in cash in lieu of shares of our common stock, the shares subject to such awards will again be available for purposes of the 2019 Plan. The share limit, however, will not be increased by the number of shares of our common stock (i) tendered, withheld, or

subject to an award surrendered in connection with the exercise of an option, (ii) that were not issued upon the net settlement or net exercise of a stock-settled SAR, (iii) deducted or delivered from payment of an award in connection with the Corporation’s tax withholding obligations, or (iv) purchased by the Corporation with proceeds from option exercises.

Limits on Awards. The maximum number of shares of our common stock subject to options or SARs that may be granted under the 2019 Plan to any person (other than anon-employee director) in a calendar year is 120,000 shares. The maximum number of shares subject to awards other than options or SARs that are stock-denominated that may be granted under the 2019 Plan to any person (other than anon-employee director) in a calendar year is 40,000 shares.

Non-Employee Director Compensation Limits. The maximum number of shares of our common stock subject to awards that may be granted under the 2019 Plan in a calendar year to anynon-employee director (calculating the value of any such awards based on the grant date fair value of such awards for financial reporting purposes), taken together with any cash fees paid to suchnon-employee director during the calendar year, shall not exceed $250,000. The foregoing limitation, however, will not apply to the extent that anon-employee director has been or becomes an employee of the Corporation during the calendar year.

Adjustments. The number and kinds of shares of common stock for which awards may be made under the 2019 Plan, including the share limit and the individual share limits described above, will be adjusted proportionately and accordingly by the Committee if the number of outstanding shares of our common stock is increased or decreased or the shares of our common stock are changed into or exchanged for a different number of shares or kind of capital stock or other securities of the Corporation on account of any recapitalization, reclassification, stock split, reverse stock split,spin-off, combination of stock, exchange of stock, stock dividend or other distribution payable in capital stock, or other increase or decrease in shares of common stock effected without receipt of consideration by the Corporation.

Fair Market Value Determination. For so long as our common stock remains listed on the NASDAQ (or listed on any other established securities exchange or traded on any other securities market), the fair market value of a share of our common stock will be the closing price for a share as quoted on such exchange or market for such date. If there is no reported closing price on such date, the fair market value of a share of our common stock will be the closing price of the common stock on the next preceding date for which such quotation exists. If our common stock is not listed on an established securities exchange or traded on an established securities market, the Committee will determine the fair market value by the reasonable application of a reasonable valuation method, in a manner consistent with Section 409A of the Code. On February 26, 2019, the closing price of our common stock as reported on the NASDAQ was $28.08 per share.

Options. The 2019 Plan authorizes our Committee to grant “incentive stock options” (as defined in Section 422 of the Code) and options that do not qualify as incentive stock options (“nonqualified options”). To the extent that the aggregate fair market value of shares of our common stock determined on the grant date with respect to which incentive stock options are exercisable for the first time during any calendar year exceeds $100,000, the option will be treated as a nonqualified option. The exercise price of each option will be determined by the Committee, provided that the per share exercise price will be equal to or greater than 100% of the fair market value of a share of our common stock on the grant date. If we were to grant incentive stock options to any ten percent shareholder, the per share exercise price will not be less than 110% of the fair market value of a share of our common stock on the grant date.

Generally, the term of an option will not exceed ten years from the grant date. If we were to grant incentive stock options to any ten percent shareholder, the term cannot exceed five years from the grant date. The Committee determines at what time or times each option may be exercised and the period of time, if any, after retirement, death, disability, or termination of employment during which options may be exercised. The vesting and exercisability of options may be accelerated by the Committee. Awards of options are nontransferable, except (i) for transfers by will or the laws of descent and distribution or (ii) if authorized in the applicable award agreement, for transfers of nonqualified options, not for value, to family members pursuant to the terms and conditions of the 2019 Plan.

Stock Appreciation Rights. The 2019 Plan authorizes the Committee to grant SARs that provide the grantee with the right to receive, upon exercise of the SARs, cash, shares of our common stock, or a combination of the foregoing. The amount that the recipient will receive upon exercise of a SAR generally will equal the excess of the fair market value of a share of our common stock on the date of exercise over the SAR’s per share exercise price, which must be equal to or greater than 100% of the fair market value of a share of our common stock on the grant date. SARs will become exercisable in accordance with terms determined by our Committee. Stock appreciation rights may be granted in tandem with an option grant or independently from an option grant. The term of a SAR cannot exceed ten years from the grant date. Awards of SARs are nontransferable, except (i) for transfers by will or the laws of descent and distribution or (ii) if authorized in the applicable award agreement, not for value, to family members pursuant to the terms and conditions of the 2019 Plan.

Restricted Stock and Restricted Stock Units. The 2019 Plan also authorizes the Committee to grant restricted stock and RSUs (including deferred stock units). Subject to the provisions of the 2019 Plan, the Committee will determine the terms and conditions of each award of restricted stock and RSUs, including the restricted period for all or a portion of the award, the restrictions applicable to the award, and the purchase price (if any) for the shares of our common stock subject to the award. Restricted stock and RSUs may vest solely by the passage of time and/or pursuant to achievement of performance goals, and the restrictions and/or the restricted period may differ with respect to each award of restricted stock and RSUs. During the period, if any, when shares of restricted stock and RSUs arenon-transferable or forfeitable or prior to the satisfaction of any other restrictions prescribed by the Committee, a grantee is prohibited from selling, transferring, assigning, pledging, or otherwise encumbering or disposing of his or her shares of restricted stock or RSUs.

A grantee of restricted stock will have all the rights of a shareholder, including the right to vote the shares and receive dividends or distributions on the shares, except to the extent limited by the Committee or the 2019 Plan. Grantees of RSUs will have no voting or dividend rights or other rights associated with share ownership, although the Committee may award dividend equivalent rights on such units. Grantees will not vest in dividends paid on unvested shares of restricted stock subject to performance-based vesting or in dividend equivalent rights paid on unvested RSUs subject to performance-based vesting, unless and until the underlying performance-based awards vest.

Unrestricted Stock. The 2019 Plan authorizes the Committee to grant shares of unrestricted stock. Shares of unrestricted stock are free of any restrictions, and a grantee of shares of unrestricted stock will have all the rights of a shareholder, including the right to vote the shares and receive dividends or distributions on the shares, as of the grant date.

Dividend Equivalent Rights. The 2019 Plan authorizes the Committee to grant dividend equivalent rights, which are rights entitling the grantee to receive credits for dividends or distributions that would be paid if the grantee had held a specified number of shares of our common stock underlying the right. The Committee may grant dividend equivalent rights to a grantee in connection with an award under the 2019 Plan, or without regard to any other award, except that no dividend equivalent rights may be granted in connection with, or related to, an option or SAR. Dividend equivalent rights may be settled in cash, shares of our common stock, or a combination of the foregoing, in a single installment or in multiple installments, as determined by the Committee. A dividend equivalent right granted as a component of another award that vests or is earned based on the achievement of performance goals may not vest or become payable until the underlying award vests.

Performance-Based Awards. The 2019 Plan authorizes the Committee to grant performance-based awards, ultimately payable in shares of our common stock or cash, in such amounts and upon such terms as determined by the Committee. Each grant of a performance-based award will have an initial cash value or an actual or target number of shares of our common stock that is established by the Committee at the grant date. The Committee may set performance goals in its discretion that, depending on the extent to which they are met, will determine the value and/or number of shares of our common stock subject to performance-based awards that will be paid out to a grantee, and the Committee will establish the performance periods for these performance-based awards.

Other Equity-Based Awards. The 2019 Plan authorizes the Committee to grant other types of equity-based awards. Other equity-based awards are payable in cash, shares of our common stock or other equity, or a combination of the foregoing, and may be restricted or unrestricted, as determined by our Committee. The terms and conditions that apply to other equity-based awards are determined by the Committee.

Forms of Payment. The exercise price for any option or the purchase price (if any) for restricted stock is generally payable (i) in cash or cash equivalents, (ii) to the extent the award agreement provides, by the surrender of shares of our common stock (or attestation of ownership of shares of our common stock) with an aggregate fair market value, on the date of such surrender, of the exercise price or purchase price, (iii) to the extent permissible by applicable law and to the extent the award agreement provides, by payment through a broker in accordance with procedures set forth by the Corporation, or (iv) to the extent the award agreement provides and/or unless otherwise specified in an award agreement, any other form permissible by applicable law, including net exercise or net settlement and, for the purchase price of restricted stock, service rendered to the Corporation or our affiliates.

Change in Control. If the Corporation experiences a “Change in Control” in which awards will not be assumed or continued by the surviving entity: (i) immediately before the Change in Control, other than performance-based awards, all restricted stock, RSUs (including deferred stock units), and dividend equivalent rights will vest, and all shares of common stock and/or cash subject to such awards will be delivered (subject to any limitations under Section 409A of the Code), and (ii) at the Committee’s discretion, (a) all options and SARs will become exercisable at least 15 days before the Change in Control and terminate if unexercised upon the consummation of the Change in Control, and/or (b) all options, SARs, restricted stock, RSUs, and dividend equivalent rights will be terminated and cashed out or redeemed for securities of equivalent value. Performance-based awards will vest or become earned at the greater of (i) deemed achievement of target level performance,pro-rated based on service through the date of the Change in Control; and (ii) actual performance as of the date reasonably proximal to the date of consummation of the Change in Control. Other equity-based awards will be governed by the terms of the applicable award agreement.

If the Corporation experiences a “Change in Control” in which awards will be assumed or continued by the surviving entity: (i) the awards will adjusted as appropriate as to the number of shares and type of capital stock to which the awards relate and, for options and SARs, as to the exercise price, and (ii) if the grantee’s service is terminated without “cause” (as defined in the 2019 Plan) within the twenty-four (24)-month period following the consummation of such Change in Control, the grantee’s award will be fully vested as of such termination and may be exercised in full, to the extent applicable, beginning on the date of such termination and for theone-year period immediately following such termination or for such longer period as the Committee shall determine (but in no event later than the original expiration of the award).

In summary, a “Change in Control” occurs under the 2019 Plan if:

Amendment, Suspension, and Termination. The Committee may amend or suspend the 2019 Plan at any time; provided that no amendment or suspension may materially impair the rights or obligations under outstanding awards, without the consent of the grantee. Our shareholders must approve any amendment to the 2019 Plan to the extent determined by the Board or if such approval is required under applicable law (including the NASDAQ regulations). Our shareholders also must approve any amendment that changes the nore-pricing rules, the option exercise price rules, or the SAR exercise price rules. The Board may terminate the 2019 Plan at any time; provided that no termination may materially impair the rights or obligations under outstanding awards, without the consent of the grantee.

No Repricing. Except in connection with certain corporate transactions involving the Corporation, the Corporation may not: (i) amend the terms of outstanding options or SARs to reduce the exercise price of such outstanding options or SARs; (ii) cancel or assume outstanding options or SARs in exchange for, or substitution of, options or SARs with an exercise price that is less than the exercise price of the original options or SARs; or (iii) cancel or assume outstanding options or SARs with an exercise price above the then-current fair market value in exchange for cash, awards, or other securities, in each case, unless such action is subject to and approved by our shareholders.

Summary of U.S. Federal Income Tax Consequences

The U.S. federal income tax consequences of awards under the 2019 Plan for grantees and the Corporation will depend on the type of award granted. The following summary description of U.S. federal income tax consequences is intended only for the general information of our shareholders. A grantee in the 2019 Plan should not rely on this description and instead should consult his or her own tax advisor.

Incentive Stock Options. The grant of an incentive stock option will not be a taxable event for the grantee or the Corporation. A grantee will not recognize taxable income upon exercise of an incentive stock option (except that the alternative minimum tax may apply), and any gain or loss realized upon a disposition of our common stock received pursuant to the exercise of an incentive stock option will be taxed as long-term capital gain or loss if the grantee holds the shares of our common stock for at least two years after the date of grant and for one year after the date of exercise (the “holding period requirement”). We will not be entitled to a business expense deduction with respect to an incentive stock option, except as discussed below.

For the exercise of an incentive stock option to qualify for the foregoing tax treatment, the grantee generally must be our employee or an employee of one of our direct corporate subsidiaries from the date the incentive stock option is granted through a date within three months before the date of exercise of the option.

If all of the foregoing requirements are met except the holding period requirement mentioned above, the grantee will recognize ordinary income upon the disposition of the shares of our common stock in an amount generally equal to the excess of the fair market value of the common stock at the time the option was exercised over the option’s exercise price (but not in excess of the gain realized on the sale). The balance of the realized gain, if any, will be capital gain. We will be allowed a business expense deduction to the extent the grantee recognizes ordinary income, subject to our compliance with Section 162(m) of the Code and to certain reporting requirements.

Nonqualified Options. The grant of a nonqualified option will not be a taxable event for the grantee or the Corporation. Upon exercising a nonqualified option, a grantee will recognize ordinary income in an amount equal to the difference between the option’s exercise price and the fair market value of the common stock on the date of exercise. Upon a subsequent sale or exchange of shares acquired pursuant to the exercise of a nonqualified option, the grantee will have taxable capital gain or loss, measured by the difference between the amount realized on the disposition and the tax basis of the shares of our common stock (generally, the amount paid for the shares plus the amount treated as ordinary income at the time the option was exercised). Capital gain or loss will be long-term if the grantee has held the shares for more than one year. Otherwise, the capital gain or loss will be short-term.

If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

A grantee who has transferred a nonqualified option to a family member by gift will realize taxable income at the time the nonqualified option is exercised by the family member. The grantee will be subject to withholding of income and employment taxes at that time. The family member’s tax basis in the shares of our common stock will be the fair market value of the shares of common stock on the date the nonqualified option is exercised. The transfer of vested nonqualified options will be treated as a completed gift for gift and estate tax purposes. Once the gift is completed, neither the transferred options nor the shares acquired on exercise of the transferred options will be includable in the grantee’s estate for estate tax purposes.

In the event a grantee transfers a nonqualified option to his or herex-spouse incident to the grantee’s divorce, neither the grantee nor theex-spouse will recognize any taxable income at the time of the transfer. In general, a transfer is made “incident to divorce” if the transfer occurs within one year after the marriage ends or if it is related to the end of the marriage (for example, if the transfer is made pursuant to a divorce order or settlement agreement). Upon the subsequent exercise of such nonqualified option by theex-spouse, theex-spouse will recognize taxable income in an amount equal to the difference between the option’s exercise price and the fair market value of the common stock at the time of exercise. Any distribution to theex-spouse as a result of the exercise of the option will be subject to employment and income tax withholding at that time.

Stock Appreciation Rights. The grant of a SAR will not be a taxable event for the grantee or the Corporation. Upon exercising a SAR, a grantee will recognize ordinary income in an amount equal to the difference between the SAR’s exercise price and the fair market value of the common stock on the date of exercise. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

Restricted Stock. A grantee who is awarded restricted stock will not recognize any taxable income for U.S. federal income tax purposes in the year of the award, provided that the shares of common stock are subject to restrictions (that is, the shares of restricted stock are nontransferable and subject to a substantial risk of forfeiture). However, the grantee may elect under Section 83(b) of the Code to recognize compensation income in the year of the award in an amount equal to the fair market value of the common stock on the date of the award (less the purchase price, if any), determined without regard to the restrictions. If the grantee does not make such Section 83(b) election, the fair market value of the common stock on the date the restrictions lapse (less the purchase price, if any) will be treated as compensation income to the grantee and will be taxable in the year the restrictions lapse, and dividends paid while the common stock is subject to restrictions will be subject to withholding taxes. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

Restricted Stock Units. The grant of restricted stock units (including deferred stock units) will not be a taxable event for the grantee or the Corporation. A grantee who receives restricted stock units will recognize ordinary income in an amount equal to the fair market value of the shares issued, or in the case of a cash-settled award, the amount of the cash payment made, to such grantee at the end of the restriction period or, if later, the payment date. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

Unrestricted Stock. The grant of unrestricted stock is a taxable event for the grantee. A grantee who receives shares of unrestricted stock will recognize ordinary income on the grant date in an amount equal to the fair market value of the shares issued, reduced by the amount, if any, paid for such shares. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income. Upon a subsequent sale or exchange of shares of unrestricted stock, the grantee will have taxable capital gain or loss, measured by the difference between the amount realized on the disposition and the tax basis of the shares of our common stock (generally, the amount paid for the shares plus the amount treated as ordinary income on the grant date). Capital gain or loss will be long-term if the grantee has held the shares for more than one year. Otherwise, the capital gain or loss will be short-term.

Dividend Equivalent Rights. The grant of dividend equivalent rights will not be a taxable event for the grantee or the Corporation. A grantee who receives dividend equivalent rights will recognize ordinary income on the date of payment in the amount distributed to the grantee pursuant to the award. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

Cash Awards. The grant of a cash award will not be a taxable event for the grantee or the Corporation. A grantee who receives a cash award will recognize ordinary income on the date of payment in the amount distributed to the grantee pursuant to the award. If we comply with applicable reporting requirements and with the restrictions of Section 162(m) of the Code, we will be entitled to a business expense deduction in the same amount and generally at the same time as the grantee recognizes ordinary income.

Section 280G of the Code. To the extent payments which are contingent on a Change in Control are determined to exceed certain limitations, such payments may be subject to a 20% excise tax, and the Corporation’s deduction with respect to the associated compensation expense may be disallowed in whole or in part. The 2019 Plan includes a Section 280G “best after tax” provision, meaning, if any of the payments under the 2019 Plan or otherwise would constitute parachute payments within the meaning of Section 280G of the Code and would be subject to the excise tax imposed under Section 4999 of the Code, the payments will be reduced by the amount required to avoid the excise tax if such a reduction would give the grantee a betterafter-tax result than if the grantee received the payments in full.

New Awards

The awards, if any, that will be made to eligible grantees under the 2019 Plan are subject to the discretion of the Committee, and thus we cannot currently determine the benefits or number of shares subject to awards that may be granted in the future to eligible grantees under the 2019 Plan. Therefore, no new plan benefits table can be provided at this time. For more information on the awards granted under the 2009 Stock Incentive Plan to our named executive officers in 2018, see the section below entitled “Outstanding Equity Awards at 2018 FiscalYear-End.” For more information on the awards granted under the 2009 Stock Incentive Plan to our directors in 2018, see the section below entitled “2018Non-Employee Director Compensation Table.”

Registration with the SEC

If the 2019 Plan is approved by our shareholders, we intend to file a Registration Statement on FormS-8 relating to the 2019 Plan with the SEC pursuant to the Securities Act as soon as is practicable after such approval.

Vote Required

The affirmative vote of a majority of the votes cast by all shareholders entitled to vote on this proposal is required to approve the 2019 Plan. For purposes of the vote on this proposal, abstentions and other shares not voted (whether by brokernon-vote or otherwise) will not be counted as votes cast and will have no effect on the result of the vote.

Our Recommendation

The Board unanimously recommends that shareholders vote FOR the resolution approving the 2019 Plan.

These risks are controlled through policies and procedures established throughout the Corporation, which are monitored and reviewed by the Board in accordance with established Corporation policies.

The Corporation’s Enterprise Risk Management (ERM)(“ERM”) program includes measurement and monitoring of the following risks: credit, market, liquidity, operational, compliance, strategic and reputation. An ERM Risk Assessment Team evaluates, analyzes, and reports annual risk assessment(s) and provides quarterly updates to the ERM Risk Steering Committee, comprised of the Executive Management Team. The Corporation’s ERM Board Committee members meet quarterly to review the overall risk profile of the Corporation. The ERM Board Committee met four times during 2017.2018. The ERM Board Committee follows an ERM Policy, Risk Philosophy Statements and Risk Appetite Statements that summarizessummarize the risk appetite of the Corporation as well as the expected reward for the risks.

In addition to the ERM Process,program, the following risks are specifically addressed as outlined below: market, credit, and liquidity risk.

Market risk is the sensitivity of net interest income and the market value of financial instruments to the direction and frequency of changes in interest rates. Market risk results from various repricing frequencies and the maturity structure of the financial instruments owned by the Corporation. The Corporation uses its asset/liability management policy and systems to control, monitor, and manage market risk. Such policies and systems are monitored by the Management Asset/Liability Committee and by the Asset/Liability Committee of the Board, which meets four times per year.

Credit risk represents the possibility that a customer may not perform in accordance with contractual terms. Credit risk results from loans with customers and the purchase of investment securities. The Corporation manages credit risk by following an established credit policy and through a disciplined evaluation of the adequacy of the allowance for loan losses. Also, the investment policy limits the amount of credit risk that may be taken in the securities portfolio. Such policies and systems are monitored by both the Asset/Liability Committee of the Board and the Loan Committee of the Board, both of which meet four times per year.

Liquidity risk represents the inability to generate or otherwise obtain funds at reasonable rates to satisfy commitments to borrowers and obligations to depositors. The Corporation has established guidelines within its asset liability management policy to manage liquidity risk. These guidelines include contingent funding alternatives. Such guidelines are monitored at least monthly by the Management Asset/Liability Committee and by the Asset/Liability Committee of the Board.

Target Pay and Mix for Compensation Elements

The ECC reviews both total compensation and each element of compensation when making pay decisions and recommendations to our Board. AlthoughWe target compensation at market median (50^th percentile) with actual compensation can bevarying above or below targets based on individual and Corporation performance, retention considerations and executive experience, we generally target base compensation within a reasonable range of the 50th percentile of the market.performance.

In allocating compensation among these elements, our program is designed to provide a balance of:

To determine the remuneration of the CEO, the ECC considers feedback from the President & CEO, as well as input from the compensation consultant as requested, to make decisions regarding the compensation of the President & CEO.Meridian on anas-requested basis.

Competitive Benchmarking

On an annual basis, the ECC reviews competitive market data and conducts a comprehensive compensation assessment. To assist in making compensation decisions, in 2017, Meridian was engaged by the ECC engaged Meridian to conduct a comprehensive review of our NEO total compensation program. The purpose of the review was to provide an independent and objective analysis of all elements of compensation (individually and in the aggregate) relative to market and peer group practices. An assessment of the pay mix and the pay for performance relationship were also presented to the ECC.

The primary data source used in examining the competitive market for the NEOs is information publicly disclosed by a peer group of other publicly traded financial corporations. AMeridian developed the peer group was developed by Meridian using objective parameters that reflect banksfinancial corporations of similar size, geographic region and business model (factors that influence NEO compensation in banks)the banking industry). Meridian excluded banksfinancial corporations in large metropolitan areas as they are not similar to the Corporation. The ECC approved the peer group. The peer group was approved by the ECC. Peer groups areis reviewed and updated as appropriate, since the comparable banksfinancial corporations may change depending on acquisitions and the business focus of the bankCorporation or our peer institutions. Overall, the goal is to have 15 to 25 comparative financial corporations that approximate our asset size and region and provide a market perspective for NEO total compensation.

20172018 Compensation Program and Pay Decisions

The Corporation’s compensation program consists of four elements: base salary, annual incentives, long-term /stock-basedlong-term/stock-based compensation, and benefits. The following section summarizes the role of each element, how decisions are made and the resulting 20172018 decision process as it relates to our NEOs.

Base Salary

The Corporation believes that a competitive base salary is essential to hire and retain NEOs andour NEOs. To that it shouldend, the Corporation aims to provide competitive fixed pay related to the role and contribution of the executiveNEO.

Our compensation consultant provides competitive market data based on its competitive assessment considering a composite of market data from the custom proxy peer group as well as other data sources of banking compensation information. The ECC uses thisthe benchmark data to provideprovided by Meridian as a reference for makingwhen setting the base salary decisions forof each NEO. The ECC targets market median but considers each executive’sNEO’s specific role, experience, contribution and performance in settingdetermining base salaries.

In December of each year, the ECC reviews and sets each NEO’s base paysalary to reflect competitive market conditions, individual experience, expertise and performance.

The 20172018 salary adjustments were as follows:

Annual Incentives

The primary objective of our annual incentive program is to motivate and reward key members of management for achieving specific corporate, department, and individual goals that support our strategic plan. Through our 20172018 NEO Incentive Plan, we offer a select group of key executives, including the NEOs, whose efforts largely determine the achievement of corporate goals and objectives, an annual cash incentive opportunity. For each NEO, there are individualalso team-based objectives that are measured using absolute metrics.

Each NEO has a target opportunity based on his position at the Corporation and group objectives, as well as relativecompetitive market data provided by Meridian. Actual payouts can range from zero if performance does not result in any goals being achieved to 150% if stretch goals are achieved for all metrics. A NEO receives a 50% payout for achieving threshold performance and absolute metrics, which varya 100% payout for achieving target goals, with interpolation among executives according to their areas of responsibility.the performance categories once the threshold has been met.
