AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of June 15, 2011 (this “Agreement”), between F.N.B. CORPORATION, a Florida corporation (“FNB”), and PARKVALE FINANCIAL CORPORATION, a Pennsylvania corporation (“PFC”).

W I T N E S S E T H:

WHEREAS, the Boards of Directors of PFC and FNB have determined that it is in the best interests of their respective companies and their shareholders to consummate the strategic business combination transaction provided for in this Agreement pursuant to which PFC will, on the terms and subject to the conditions set forth in this Agreement, merge with and into FNB (the “Merger”), so that FNB is the surviving company in the Merger (sometimes referred to in such capacity as the “Surviving Company”); and

WHEREAS, for federal income Tax (as defined in Section 3.10(b)) purposes, it is intended that the Merger shall qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”); and

WHEREAS, the parties desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual representations, warranties, covenants and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE 1

THE MERGER

1.1 The Merger.

Subject to the terms and conditions of this Agreement, in accordance with the Pennsylvania Business Corporation Law (the “PBCL”) and the Florida Business Corporation Act (the “FBCA”), at the Effective Time (as defined in Section 1.2) PFC shall merge with and into FNB. FNB shall be the Surviving Company in the Merger, and shall continue its corporate existence under the laws of the State of Florida. As of the Effective Time, the separate corporate existence of PFC shall cease.

1.2 Effective Time.

The Merger shall become effective as set forth in the articles of merger (the “Articles of Merger”) that shall be filed with the Secretary of State of the Commonwealth of Pennsylvania and the Secretary of State of the State of Florida on or before the Closing Date (as defined in Section 9.1). The term “Effective Time” shall mean the date and time when the Merger becomes

- 1 -

effective as set forth in the Articles of Merger. “Effective Date” shall mean the date on which the Effective Time occurs.

1.3 Effects of the Merger.

(a) Effects Under PBCL and FBCA. At and after the Effective Time, the Merger shall have the effects set forth in Section 1929 of the PBCL and Section 607.1106 of the FBCA.

(b) Directors and Executive Officers of the Surviving Company. The directors of the Surviving Company immediately after the Merger shall be the (i) directors of FNB immediately prior to the Merger, and (ii) one (1) current member of PFC’s Board of Directors (the “PFC Designee”), who shall be Xxxxxx X. XxXxxxxx, Xx. If Xx. XxXxxxxx does not become a director of the Surviving Company because of death or disability, FNB agrees, after consultation with the members of the Board of Directors of PFC, to cause a member of the PFC Board of Directors as of the date hereof who is mutually agreeable to FNB and PFC to be elected or appointed to the Board of Directors of the Surviving Company as the PFC Designee. The executive officers of the Surviving Company immediately after the Merger shall be the executive officers of FNB immediately prior to the Merger.

1.4 Conversion of PFC Capital Stock.

(a) Subject to the provisions of this Agreement, each share of common stock, par value $1.00 per share, of PFC (“PFC Common Stock”) issued and outstanding immediately prior to the Effective Time, other than Treasury Shares (as defined in Section 1.4(c)) shall, by virtue of the Merger, no longer be outstanding and shall as of the Effective Time automatically be converted into and shall thereafter represent the right to receive as merger consideration (the “Common Stock Merger Consideration”) 2.178 shares (the “Exchange Ratio”) of common stock, $0.01 par value, of FNB (“FNB Common Stock”).

(b) In the event each issued and outstanding share of the Fixed Rate Cumulative Perpetual Preferred Stock, Series A, par value $1.00 per share, stated liquidation amount $1,000 per share, of PFC (the “PFC Series A Preferred Stock”) is not purchased or redeemed prior to or contemporaneous with the Merger, then each share of the PFC Series A Preferred Stock issued and outstanding immediately prior to the Effective Time (other than any shares of PFC Series A Preferred Stock to be cancelled in accordance with Section 1.4(c)) shall no longer be outstanding and shall as of the Effective Time automatically be converted into and shall thereafter represent the right to receive, subject to the other provisions of this Article 1, one share (the “Preferred Stock Merger Consideration” and, together with the Common Stock Merger Consideration, the “Merger Consideration”) of the FNB Preferred Stock to be designated, prior to the Closing Date, as Fixed Rate Cumulative Perpetual Preferred Stock, Series D, stated liquidation amount $1,000 per share (the “FNB Series D Preferred Stock”), and otherwise having rights, preferences, privileges and voting powers such that the rights, preferences, privileges and voting powers of the PFC Series A Preferred Stock are not adversely affected by such conversion and having rights, preferences and privileges and voting powers, and limitations and restrictions that, taken as a whole, are not materially less favorable than the

- 2 -

rights, preferences, privileges and voting powers, and limitations and restrictions of the PFC Series A Preferred Stock immediately prior to such conversion, taken as a whole.

(c) At and after the Effective Time, each Treasury Share shall be cancelled and retired and no shares of FNB Common Stock or other consideration shall be issued in exchange therefor. “Treasury Shares” means shares of PFC Common Stock and any outstanding PFC Series A Preferred Stock (together, the “PFC Capital Stock”) held by PFC or any of the PFC Subsidiaries (as defined in Section 3.1(c)) or by FNB or any of its Subsidiaries, other than in a fiduciary, including custodial or agency, capacity or as a result of debts previously contracted in good faith.

(d) At the Effective Time, the stock transfer books of PFC shall be closed as to holders of PFC Capital Stock immediately prior to the Effective Time and no transfer of PFC Capital Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, certificates representing PFC Capital Stock (“Certificates”) are properly presented in accordance with Section 2.2 of this Agreement to the Exchange Agent (as defined in Section 2.1), such Certificates shall be cancelled and exchanged for FNB Common Stock or FNB Series D Preferred Stock (together, the “FNB Capital Stock”), as applicable, held in book entry representing the number of whole shares into which the PFC Capital Stock represented by the Certificates was converted in the Merger, plus, if applicable pursuant to Section 1.4(f), any payment for any fractional share of FNB Common Stock without any interest thereon and any dividends or distributions to which the holder of such Certificates is entitled pursuant to Section 2.2(b).

(e) Each holder of PFC Common Stock shall have the option of enrolling the whole shares of FNB Common Stock issuable to such shareholder upon the consummation of the Merger in FNB’s Dividend Reinvestment and Direct Stock Purchase Plan (the “DRSP Plan”). Each PFC shareholder electing to enroll in the DRSP Plan shall be issued FNB Common Stock held in book entry representing the number of whole shares received in the Merger.

(f) Notwithstanding any other provision of this Agreement, each holder of PFC Common Stock who would otherwise be entitled to receive a fractional share of FNB Common Stock, after taking into account all Certificates delivered by such holder, shall receive an amount in cash, without interest, rounded to the nearest cent, equal to the product obtained by multiplying (a) the Average Closing Price (as defined below) as of the Closing Date by (b) the fraction of a share (calculated to the nearest ten-thousandth when expressed in decimal form) of FNB Common Stock, to which such holder would otherwise be entitled. No such holder shall be entitled to dividends or other rights in respect of any such fractional shares. “Average Closing Price” means, as of any specified date, the average composite closing price of FNB Common Stock on the New York Stock Exchange, including any successor exchange (“NYSE”), as reported by the NYSE for the twenty (20) consecutive trading days ending on and including the fifth such trading day prior to the specified date rounded to the nearest ten-thousandth.

- 3 -

1.5 FNB Capital Stock. At and after the Effective Time, each share of FNB capital stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

1.6 PFC Equity and Equity-Based Awards.

(a) PFC Stock Options. Effective as of the Effective Time, each then outstanding option to purchase shares of PFC Common Stock (each a “PFC Stock Option”), pursuant to the equity-based compensation plans identified in Section 3.11(a) of the PFC Disclosure Schedule (as defined in Article 3 hereof) (the “PFC Stock Plans”) and the award agreements evidencing the grants thereunder, granted to any current or former employee or director of PFC or any of the PFC Subsidiaries (as defined in Section 3.1(c)) shall at the Effective Time cease to represent a right to acquire shares of PFC Common Stock and shall be converted automatically into a fully vested and exercisable option to acquire shares of FNB Common Stock on the terms hereinafter set forth. FNB shall assume each such PFC Stock Option in accordance with the terms of the relevant PFC Stock Plan and stock option or other agreement by which it is evidenced, except that from and after the Effective Time: (i) FNB and the Compensation Committee of its Board of Directors, including, if applicable, the entire Board of Directors of FNB, shall be substituted for PFC and the compensation committee of the Board of Directors of PFC, including, if applicable, the entire Board of Directors of PFC, administering such PFC Stock Plan, (ii) each PFC Stock Option assumed by FNB may be exercised solely for shares of FNB Common Stock, (iii) the number of shares of FNB Common Stock subject to such PFC Stock Option shall be equal to the number of shares of PFC Common Stock subject to such PFC Stock Option immediately prior to the Effective Time multiplied by the Exchange Ratio, provided that any fractional shares of FNB Common Stock resulting from such multiplication shall be rounded down to the nearest share, and (iv) the exercise price per share of FNB Common Stock under each such option shall be the amount (rounded up to the nearest whole cent) equal to the per share exercise price under each such PFC Stock Option prior to the Effective Time divided by the Exchange Ratio. Notwithstanding clauses (iii) and (iv) of the preceding sentence, each PFC Stock Option that is an “incentive stock option” shall be adjusted as required by Section 424 of the Code, and regulations promulgated thereunder, so as not to constitute a modification, extension or renewal of the option within the meaning of Section 424(h) of the Code. FNB and PFC agree to take all reasonable and necessary steps to effect the provisions of this Section 1.6(a). As of the Effective Time, FNB shall issue to each holder of each outstanding PFC Stock Option that has been assumed by FNB (the “Assumed Stock Options”) a document evidencing the conversion and assumption of such PFC Stock Option by FNB pursuant to this Section 1.6(a). Prior to the Effective Time, FNB shall reserve for issuance the number of shares of FNB Common Stock necessary to satisfy FNB’s obligations under this Section 1.6(a). As soon as practicable after the Effective Time, FNB shall file and cause to become effective a registration statement or statements on Form S-8 or Form S-3 (or any successor or other applicable form) with respect to the shares of FNB Common Stock subject to the Assumed Stock Options, and to maintain the effectiveness of such registration statement for so long as any PFC Stock Options remain outstanding.

(b) Warrant. The Warrant issued on December 23, 2008 to the U.S. Department of the Treasury (“Treasury Department”) in connection with the issuance of the PFC Series A Preferred Stock (the “PFC Warrant”) shall, by virtue of the Merger and without

- 4 -

any action on the part of any Person, cease to be a warrant to purchase PFC Common Stock and will be converted automatically into a warrant to purchase FNB Common Stock (the “FNB Warrant”) in accordance with the terms of the PFC Warrant, and FNB will assume such warrant subject to its terms; provided, however, that after the Effective Time:

(i) the number of shares of FNB Common Stock purchasable upon exercise of the FNB Warrant will equal the product of (x) the number of shares of PFC Common Stock that were purchasable pursuant to the PFC Warrant immediately before the Effective Time and (y) the Exchange Ratio, rounded to the nearest one-hundredth (1/100th) of a share; and

(ii) the per share exercise price for the PFC Warrant will equal the quotient of (x) the per share exercise price of the PFC Warrant in effect immediately before the Effective Time and (y) the Exchange Ratio, rounded to the nearest one-tenth (1/10th) of a cent.

1.7 Articles of Incorporation and Bylaws of the Surviving Company. The FNB Charter (as defined in Section 4.1(b)) as in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Company until thereafter amended in accordance with applicable law. The FNB Bylaws (as defined in Section 4.1(b)) as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Company until thereafter amended in accordance with applicable law.

1.8 Tax Consequences. It is intended that the Merger shall constitute a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

1.9 Dissenting Shares. No outstanding shares of PFC Common Stock shall have any dissenters’ rights of appraisal under the PBCL.

1.10 The Bank Merger. As soon as practicable after the execution of this Agreement, PFC and FNB shall cause Parkvale Savings Bank (“PFC Bank”) and First National Bank of Pennsylvania (“FNB Bank”) to enter into a bank merger agreement, the form of which is attached to this Agreement as Exhibit “A” (the “Bank Merger Agreement”), that provides for the merger of PFC Bank with and into FNB Bank (the “Bank Merger”), in accordance with applicable laws and regulations and the terms of the Bank Merger Agreement and as soon as practicable after consummation of the Merger. The Bank Merger Agreement provides that the directors of FNB Bank (“FNB Bank Board”) upon consummation of the Bank Merger shall be the directors of FNB Bank immediately prior to the Bank Merger plus the PFC Bank Designee (as defined in Section 6.14(b)).

1.11 Right to Revise Structure. FNB may at any time change the method of effecting the combination contemplated by this Agreement if and to the extent it deems such a change to be desirable; provided, however, that no such change shall (i) alter or change the amount or kind of the Common Stock Merger Consideration (as defined in Section 1.4(a)) provided for in this Agreement, (ii) adversely affect the Tax treatment of PFC’s shareholders as a result of receiving the Merger Consideration or the Tax treatment of either party pursuant to this Agreement, or (iii) materially impede or delay consummation of the transactions this Agreement contemplates. In

- 5 -

the event FNB elects to make such a change, the parties agree to execute appropriate documents to reflect the change.

ARTICLE 2

EXCHANGE OF SHARES

2.1 FNB to Make Merger Consideration Available. As promptly as practicable following the Effective Time, FNB shall deposit, or shall cause to be deposited, with Registrar and Transfer Company (“Exchange Agent”), for the benefit of the holders of Certificates, for exchange in accordance with this Article 2, (a) book entry shares representing the aggregate number of shares of FNB Capital Stock issuable pursuant to this Agreement in exchange for shares of PFC Capital Stock outstanding immediately prior to the Effective Time of the Merger, (b) immediately available funds equal to any dividends or distributions payable in accordance with Section 2.2(b), and (c) cash in lieu of any fractional shares of FNB Common Stock to be issued pursuant to Section 1.4(f) and paid pursuant to Section 1.4 in exchange for outstanding shares of PFC Capital Stock (such cash and book entry shares for shares of FNB Capital Stock, collectively being referred to as the “Exchange Fund”). The Exchange Fund shall not be used for any purpose other than to fund payments due pursuant to Section 2.2 except as otherwise provided in this Agreement.

2.2 Exchange Shares.

(a) As soon as practicable after the Effective Time, and in no event more than five business days thereafter, the Exchange Agent shall mail to each holder of record of PFC Capital Stock a letter of transmittal in customary form as prepared by FNB and reasonably acceptable to PFC which shall specify, among other things, that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration and any cash in lieu of fractional shares into which the shares of PFC Common Stock represented by such Certificate or Certificates shall have been converted pursuant to this Agreement and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(b). After the Effective Time of the Merger, each holder of a Certificate formerly representing PFC Capital Stock, other than Treasury Shares, who surrenders or has surrendered such Certificate or customary affidavits and indemnification regarding the loss or destruction of such Certificate, together with duly executed transmittal materials to the Exchange Agent, shall, upon acceptance thereof, be entitled to book entry shares representing FNB Common Stock or FNB Series D Preferred Stock, as applicable, into which the shares of PFC Capital Stock shall have been converted pursuant to Section 1.4, as well as any cash in lieu of any fractional share of FNB Common Stock to which such holder would otherwise be entitled and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(b). The Exchange Agent shall accept such Certificate upon compliance with such reasonable and customary terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal practices. Until surrendered as contemplated by this Section 2.2, (i) each Certificate representing PFC Common Stock shall be deemed from and after the Effective Time of the Merger to evidence only the right to receive the Common Stock Merger Consideration, any cash in lieu of fractional shares into which the

- 6 -

shares of PFC Common Stock represented by such Certificate or Certificates shall have been converted pursuant to this Agreement and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(b), and (ii) any Certificate representing PFC Series A Preferred Stock shall be deemed from and after the Effective Time of the Merger to evidence only the right to receive the Preferred Stock Merger Consideration and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(b). FNB shall not be obligated to deliver the Merger Consideration or any check representing cash in lieu of fractional shares and/or declared but unpaid dividends to which any former holder of PFC Capital Stock is entitled as a result of the Merger until such holder surrenders his Certificate or Certificates for exchange as provided in Section 2.2. If any shares of FNB Capital Stock, or any check representing cash in lieu of fractional shares and/or declared but unpaid dividends, is to be issued in a name other than that in which a Certificate surrendered for exchange is issued, the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the person requesting such exchange shall affix any requisite stock transfer tax stamps to the Certificate surrendered or provide funds for their purchase or establish to the satisfaction of the Exchange Agent that such taxes are not payable. If any Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit, in form and substance reasonably acceptable to FNB, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by FNB or the Exchange Agent, the posting by such Person of a bond in such amount as FNB and the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it, FNB or the Surviving Company with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

No trust funding any PFC Plan is intended to meet the requirements of Code Section 501(c)(9). None of PFC and the PFC Subsidiaries nor any other person, including any fiduciary, has engaged in any “prohibited transaction”, as defined in Section 4975 of the Code or Section 406 of ERISA, which would reasonably be expected to

- 19 -

subject any of the PFC Plans or their related trusts, PFC, any of the PFC Subsidiaries or any person that PFC or any of PFC Subsidiaries has an obligation to indemnify, to any material Tax or penalty imposed under Section 4975 of the Code or Section 502 of ERISA.

(f) (i) No PFC Benefit Plan is a Multiemployer Plan or a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA (a “Multiple Employer Plan”), (ii) none of PFC and the PFC Subsidiaries nor any of their respective ERISA Affiliates has, at any time during the last six years, contributed to or been obligated to contribute to any Multiemployer Plan or Multiple Employer Plan and (iii) none of PFC and the PFC Subsidiaries nor any of their respective ERISA Affiliates has incurred, during the last six years, any Withdrawal Liability that has not been satisfied in full. There does not now exist, nor do any circumstances exist that would reasonably be likely to result in, any Controlled Group Liability that would be a liability of PFC or any of the PFC Subsidiaries following the Effective Time, other than such liabilities that arise solely out of, or relate solely to, the PFC Benefit Plans. Without limiting the generality of the foregoing, neither PFC nor any of the PFC Subsidiaries, nor, to PFC’s knowledge, any of their respective ERISA Affiliates, has engaged in any transaction described in Sections 4069, 4204 or 4212 of ERISA.

(g) Except as set forth in Section 3.11(g) of the PFC Disclosure Schedule, PFC and the PFC Subsidiaries have no liability for life, health, medical or other welfare benefits to former employees or beneficiaries or dependents thereof, except for health continuation coverage as required by Section 4980B of the Code, Part 6 of Title I of ERISA or applicable law and at no expense to PFC and the PFC Subsidiaries.

(h) Except as set forth in Section 3.11(h) of the PFC Disclosure Schedule, neither the execution nor the delivery of this Agreement nor the consummation of the transactions this Agreement contemplates will, either alone or in conjunction with any other event, whether contingent or otherwise, (i) result in any payment or benefit becoming due or payable, or required to be provided, to any director, employee or independent contractor of PFC or any of PFC Subsidiaries, (ii) increase the amount or value of any benefit or compensation

- 20 -

otherwise payable or required to be provided to any such director, employee or independent contractor, (iii) result in the acceleration of the time of payment, vesting or funding of any such benefit or compensation including deferred compensation, or (iv) result in any amount failing to be deductible by reason of Section 280G of the Code or would be subject to an excise tax under Section 4999 of the Code or additional tax under Section 409A of the Code.

4.17 Reorganization. As of the date of this Agreement, FNB is not aware of any fact or circumstance that could reasonably be expected to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

4.18 Loans; Nonperforming and Classified Assets.

(a) Except as set forth in Section 4.18 of the FNB Disclosure Schedule, each Loan on the books and records of FNB and its Subsidiaries was made and has been serviced in all material respects in accordance with their customary lending standards in the ordinary course of business, is evidenced in all material respects by appropriate and sufficient documentation and, to the knowledge of FNB, constitutes the legal, valid and binding obligation of the obligor named in the Contract evidencing such Loan, subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws of general applicability relating to or affecting creditor’s rights or by general equity principles.

(b) FNB has set forth in Section 4.18 of the FNB Disclosure Schedule as to FNB and each FNB Subsidiary as of the latest practicable date prior to the date of this Agreement: (A) any written or, to FNB’s knowledge, oral Loan under the terms of which the obligor is 90 or more days delinquent in payment of principal or interest, or to FNB’s knowledge, in default of any other material provision thereof, (B) each Loan that has been classified as “substandard,” “doubtful,” “loss” or “special mention” or words of similar import by FNB, a FNB Subsidiary or an applicable regulatory authority, (C) a listing of OREO and (D) each Loan with any director, executive officer or five percent or greater shareholder of FNB or a FNB Subsidiary, or to the knowledge of FNB, any Person controlling, controlled by or under common control with any of the foregoing.

4.19 Fiduciary Accounts. FNB and each of its Subsidiaries has properly administered all accounts for which it acts as a fiduciary, including but not limited to accounts for which it serves as a trustee, agent, custodian, personal representative, guardian, conservator or investment advisor, in accordance with the terms of the governing documents and applicable laws and regulations. To FNB’s knowledge, neither FNB nor any of its Subsidiaries, nor any of their

- 37 -

respective directors, officers or employees, has committed any breach of trust with respect to any fiduciary account, and the records for each such fiduciary account are true and correct and accurately reflect the assets of such fiduciary account.

4.20 Allowance for Loan Losses. FNB Bank’s allowance for loan losses is sufficient at the date of this Agreement for its reasonably anticipated loan losses, is in compliance with the standards established by applicable Governmental Entities and GAAP and, to the knowledge of FNB, is adequate.

4.21 Interested Shareholder Status. Neither FNB nor any of its Subsidiaries is an “interested shareholder” of PFC, as such term is defined in Section 2553 of the PBCL.

Each of PFC and FNB agree that none of the respective information supplied or to be supplied by it for inclusion or incorporation by reference in the Proxy Statement and any amendment or supplement thereto shall contain any untrue statement of a material fact or omit to state any material fact required to be stated in this Agreement or necessary to make the statements in this Agreement not misleading. Each of PFC and FNB further agree that if such party shall become aware prior to the Effective Time of any information furnished by such party that would cause any of the statements in the Registration Statement or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements in this Agreement not false or misleading, to promptly inform the other parties thereof and an appropriate amendment or supplement describing such information shall be filed promptly with the SEC and, to the extent required by law, disseminated to the shareholders of PFC and/or FNB.

(c) FNB agrees to advise PFC, promptly after FNB receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of FNB Common Stock for offering or sale in any jurisdiction, of the initiation or, to the extent FNB is aware thereof, threat of any proceeding for any such purpose, or of any request by the SEC for an amendment or supplement of the Registration Statement or for additional information.

FNB agrees that it will file all appropriate applications or notices with each Regulatory Agency or Governmental Entity having jurisdiction over the transactions contemplated by this Agreement within 60 days following the date hereof. PFC and FNB shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to PFC or FNB, as the case may be, and any of their respective Subsidiaries, which appear in any filing made with, or written materials submitted to, any third party, Regulatory Agency or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties shall act reasonably and as promptly as practicable. The parties shall consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties, Regulatory Agencies and Governmental Entities necessary or advisable to consummate the transactions this Agreement contemplates and each party will keep the other apprised of the status of matters relating to completion of the transactions this Agreement contemplates. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to require FNB to

- 45 -

take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of third parties, Regulatory Agencies or Governmental Entities, that would reasonably be expected to have a Material Adverse Effect on FNB, including the Surviving Company after giving effect to the Merger, after the Effective Time (a “Materially Burdensome Regulatory Condition”). In addition, PFC agrees to cooperate and use its reasonable best efforts to assist FNB in preparing and filing such petitions and filings, and in obtaining such permits, consents, approvals and authorizations of third parties, Regulatory Agencies and Governmental Entities, that may be necessary or advisable to effect any mergers and/or consolidations of Subsidiaries of PFC and FNB following consummation of the Merger.

(f) Each of FNB and PFC shall promptly provide each other with any written communications received from any Regulatory Agency or Governmental Entity with respect to the transactions contemplated by this Agreement and will promptly advise the other upon receiving any oral communication with respect to the transactions contemplated by this Agreement from any Regulatory Agency or Governmental Entity whose consent or approval is required for consummation of the transactions this Agreement contemplates that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval (as defined in Section 7.1(c)) will not be obtained or that the receipt of any such approval may be materially delayed.

(g) PFC and FNB shall consult with each other before issuing any press release with respect to the Merger or this Agreement and shall not issue any such press release or make any such public statements without the prior consent of the other party, which shall not be unreasonably withheld; provided, however, that a party may, without the prior consent of the other party, but after such consultation, to the extent practicable under the circumstances, issue such press release or make such public statements as may upon the advice of outside counsel be required by law or the rules or regulations of the SEC, the FDIC, the OCC, the NYSE or FINRA.

PFC shall, and shall cause each of its Subsidiaries to, provide to FNB a copy of each report, schedule and other document filed or received by it during such period pursuant to the requirements of federal or state banking laws other than reports or documents that such party is not permitted to disclose under applicable law. Neither PFC nor FNB nor any of their Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of such party or its Subsidiaries or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties shall make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply to the extent possible in light of those restrictions.

(b) All information and materials provided pursuant to this Agreement shall be subject to the provisions of the Confidentiality Agreements entered into between PFC and FNB (the “Confidentiality Agreements”).

(c) No investigation by either of the parties or their respective representatives shall affect the representations and warranties of the other set forth in this Agreement.

6.3 PFC Shareholder Approval. PFC shall call a meeting of its shareholders for the purpose of obtaining the requisite shareholder approval required in connection with this Agreement and the Merger (the “PFC Shareholders Meeting”), and shall use its reasonable best efforts to call such meeting as soon as reasonably practicable following the Registration Statement being declared effective giving reasonable time for printing and mailing and taking into account the timing of its annual meeting of shareholders. Subject to Section 6.11, the Board of Directors of PFC shall recommend approval and adoption of this Agreement, the Merger and the other transactions this Agreement contemplates, by PFC’s shareholders and shall include such recommendation in the Proxy Statement (the “PFC Recommendation”).

- 47 -

6.6 Benefit Plans.

(a) Following the Effective Time, FNB shall take all reasonable action so that employees of PFC and the PFC Subsidiaries shall be entitled to participate, effective as soon as administratively practicable following the Effective Time, in each employee benefit plan, program or arrangement of FNB of general applicability with the exception of FNB’s defined benefit pension plan and any other plans frozen to new participants (the “FNB Plans”) to the same extent as similarly-situated employees of FNB and its Subsidiaries, it being understood that inclusion of the employees of PFC and the PFC Subsidiaries in the FNB Plans may occur at different times with respect to different plans, provided that coverage shall be continued under corresponding Benefit Plans of PFC and the PFC Subsidiaries until such employees are permitted to participate in the FNB Plans and provided further, however, that nothing contained in this Agreement shall require FNB or any of its Subsidiaries to make any grants to any former employee of PFC under any discretionary equity compensation plan of FNB. FNB shall cause each FNB Plan in which employees of PFC and the PFC Subsidiaries are eligible to participate to recognize, for purposes of determining eligibility to participate in, the vesting of benefits under the FNB Plans and the entitlement to benefits under the FNB Plans (including, but not limited to, severance benefit and vacation plans), the service of such employees with PFC and the PFC Subsidiaries (or predecessor companies) to the same extent as such service was credited for such purpose by PFC or the PFC Subsidiaries, provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits. Except for the commitment to continue those Benefit Plans of PFC and the PFC Subsidiaries that correspond to FNB Plans until employees of PFC and the PFC Subsidiaries are included in such FNB Plans, nothing in this Agreement shall limit the ability of FNB to amend or terminate any of PFC’s Benefit Plans in accordance with and to the extent permitted by their terms at any time permitted by such terms.

(b) At and following the Effective Time, and except as otherwise provided in Section 6.6(d), FNB shall honor, and, to the extent required by any individual agreement, assume, and the Surviving Company shall continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of PFC and the PFC Subsidiaries and current and former directors of PFC and the PFC Subsidiaries existing as of the Effective Date, as well as all employment, executive severance or “change-in-control” or similar agreements, plans or policies of PFC that are set forth in Section 6.6(b) of the PFC Disclosure Schedule. The severance or termination payments that are payable pursuant to any such severance agreements, plans or policies of PFC are described in Section 6.6(b) of the PFC Disclosure Schedule. Following the consummation of the Merger and for one year thereafter, FNB shall, to the extent not duplicative of other severance benefits, pay employees of PFC or its Subsidiaries whose employment is terminated by FNB for reasons other than cause, severance as set forth in Section 6.6(b) of the FNB Disclosure Schedule. Following the expiration of the foregoing severance policy, any years of service recognized for purposes of this Section 6.6(b) will be taken into account under the terms of any applicable severance policy of FNB or its Subsidiaries.

(c) At such time as employees of PFC and the PFC Subsidiaries become eligible to participate in a medical, dental or health plan of FNB or its Subsidiaries, to the extent reasonably practicable and available from its insurers, cause each such plan to (i) waive any

preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of PFC and its Subsidiaries, (ii) honor under such plans any deductibles, co-payments and out-of-pocket expenses incurred by the employees of PFC and its Subsidiaries and their beneficiaries during the portion of the plan year prior to such participation, and (iii) waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to such employee or dependent on or after the Effective Time to the extent such employee or dependent had satisfied any similar limitation or requirement under an analogous Benefit Plan prior to the Effective Time.

(d) PFC shall permit the PFC Employee Stock Ownership Plan as amended and restated effective as of January 1, 2008 (the “ESOP”) to terminate in accordance with its terms effective as of the occurrence of a “change in control” as defined in Section 7.4(e) of the ESOP (the “ESOP CIC Date”) and the accounts of all participants and beneficiaries in the ESOP as of the ESOP CIC Date to become fully vested as of the ESOP CIC Date. All shares of PFC Common Stock held in the ESOP shall be converted into the Common Stock Merger Consideration. As soon as practicable after the date hereof, PFC shall, after consultation with FNB, file or cause to be filed all necessary documents with the IRS for a determination letter that the termination of the ESOP as of the ESOP CIC Date will not adversely affect the ESOP’s qualified status, with a copy to be provided to FNB and its counsel. Prior to the Effective Time, PFC and, following the Effective Time, FNB shall use their respective reasonable best efforts to obtain such favorable determination letter (including, but not limited to, adopting such amendments to the ESOP as may be requested by the IRS as a condition to its issuance of a favorable determination letter). As soon as practicable following the later of the Effective Time or the receipt of a favorable determination letter from the IRS regarding the qualified status of the ESOP upon its termination, the account balances in the ESOP shall be either distributed to participants and beneficiaries or transferred to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct, except that ESOP participants whose employment is terminated by FNB may elect to receive their ESOP account balance prior to the receipt of the IRS determination letter but following their termination of employment. FNB agrees to permit ESOP participants who become employees of FNB and its Subsidiaries to roll over their account balances in the ESOP to the FNB 401(k) Plan.

(e) Immediately prior to the Effective Time, PFC shall, at the written request of FNB, freeze or terminate such of the PFC Benefit Plans as is requested by FNB, provided that such request is received from FNB in a timely manner.

(f) In order to assist with a smooth transition of the operations of PFC and its Subsidiaries and the transactions which this Agreement contemplates, FNB or one of its Subsidiaries agree to offer employment to certain officers and employees of PFC and its Subsidiaries as employees of FNB and its Subsidiaries following the Effective Time upon the terms and subject to the conditions set forth in Section 6.6(f) of the FNB Disclosure Schedule.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including any such claim, action, suit, proceeding or investigation (each a “Claim”) in which any individual who is now, or has been at

- 49 -

any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of PFC or any of PFC Subsidiaries or who is or was serving at the request of PFC or any of PFC Subsidiaries as a director, officer, employee, member or otherwise of another Person (the “Indemnified Parties”), is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director or officer of PFC or any of PFC Subsidiaries or was serving at the request of PFC or any of PFC Subsidiaries as a director or officer of another Person or (ii) this Agreement or any of the transactions this Agreement contemplates, whether asserted or arising before or after the Effective Time, the parties shall cooperate and use their best efforts to defend against and respond thereto. From and after the Effective Time, FNB shall, and shall cause the Surviving Company to, indemnify, defend and hold harmless, as and to the fullest extent currently provided under applicable law, the PFC Articles, the PFC Bylaws as in effect on the date hereof and any agreement set forth in Section 6.7 of the PFC Disclosure Schedule, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses, including reimbursement for reasonable fees and expenses, including fees and expenses of legal counsel, including local counsel, incurred in advance of the final disposition of any claim, suit, proceeding or investigation upon receipt of any undertaking required by applicable law, judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation.

(b) FNB and the Surviving Company agree that all rights to indemnification of liabilities, including advancement of expenses, and all limitations with respect thereto, existing in favor of any Indemnified Person, as provided in the PFC Articles or the PFC Bylaws, shall survive the Merger and shall continue in full force and effect, without any amendment thereto; provided, however, that in the event any Claim is asserted or made, any determination required to be made with respect to whether an Indemnified Person’s conduct complies with the standards set forth under the PBCL, the PFC Articles or the PFC Bylaws, as the case may be, shall be made by independent legal counsel, whose fees and expenses shall be paid by FNB and the Surviving Company, selected by such Indemnified Person and reasonably acceptable to FNB; and, provided further that nothing in this Section 6.7 shall impair any rights or obligations of any current or former director or officer of PFC or its Subsidiaries, including pursuant to the respective organizational documents of PFC, or their respective Subsidiaries, under the PBCL or otherwise.

(c) Prior to the Effective Time, FNB shall obtain at the expense of PFC, and FNB shall maintain for a period of six years following the Effective Time, directors’ and officers’ liability insurance and fiduciary liability insurance policies in respect of acts or omissions occurring at or prior to the Effective Time, including the transactions this Agreement contemplates, covering the Indemnified Persons who as of the Effective Time are covered by PFC’s directors’ and officers’ liability insurance or fiduciary liability insurance policies, provided that FNB may substitute therefor policies of at least the same coverage and amounts containing terms and conditions that are not less advantageous than such policies of PFC or single premium tail coverage with policy limits equal to PFC’s existing coverage limits, provided that in no event shall FNB be required to expend for any one year an amount in excess of 150% of the annual premium currently paid by PFC for such insurance (the “Insurance Amount”), and further provided that if FNB is unable to maintain or obtain the insurance called for by this Section 6.7(c) as a result of the preceding provision, FNB shall use its commercially

- 50 -

reasonable best efforts to obtain the most advantageous coverage as is available for the maximum Insurance Amount. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid policies have been obtained prior to the Effective Time from an insurer or insurers selected by FNB that have an insurer financial strength rating by A.M. Best Co. of at least “A”, which policies provide the Indemnified Persons with coverage, from the Effective Time to the sixth anniversary of the Effective Time, including in respect of the transactions this Agreement contemplates, on terms that are no less advantageous to Indemnified Persons than PFC’s D&O Insurance existing immediately prior to the date of this Agreement. If such prepaid policies have been obtained prior to the Effective Time, then the FNB shall maintain such policies in full force and effect and continue the obligations thereunder.

(d) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, including any merger between a Subsidiary of FNB, on the one hand, and a Subsidiary of PFC, on the other hand, or to vest the Surviving Company with full title to all properties, assets, rights, approvals, immunities and franchises of either party to the Merger, the proper officers and directors of each party and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by, and at the sole expense of, FNB.

6.9 Advice of Changes. Each of FNB and PFC shall promptly advise the other of any change or event (i) having or reasonably likely to have a Material Adverse Effect on it or (ii) that it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties or covenants contained in this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties, or remedies with respect thereto, or the conditions to the obligations of the parties under this Agreement; provided, further, that a failure to comply with this Section 6.9 shall not constitute the failure of any condition set forth in Article VII to be satisfied unless the underlying Material Adverse Effect or material breach would independently result in the failure of a condition set forth in Article VII to be satisfied.

6.10 Dividends. PFC may pay regular quarterly cash dividends on the PFC Common Stock at a rate not in excess of the regular quarterly cash dividend ($0.02 per share) declared prior to the date of this Agreement on the PFC Common Stock, provided that, notwithstanding the foregoing provisions of this Section 6.10, after the date of this Agreement PFC shall coordinate the declarations of any dividends in respect of the PFC Common Stock and the record dates and payment dates relating thereto with FNB’s declaration of regular quarterly dividends on the FNB Common Stock and the record dates and payment dates relating thereto, it being the intention of PFC and FNB that holders of PFC Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of PFC Common Stock and any shares of FNB Common Stock such holders receive in exchange therefor in the Merger.

By FNB, or by PFC provided that PFC shall not be in material breach of any of its obligations under Section 6.3, if any approval of the shareholders of PFC this Agreement contemplates shall not have been obtained by reason of the failure to obtain the required vote at the PFC Shareholders Meeting or at any adjournment or postponement thereof.

8.2 Effect of Termination. In the event of termination of this Agreement by either FNB or PFC as provided in Section 8.1, this Agreement shall forthwith become void and have no effect except (i) Sections 6.2(b), 6.11(f)-(i), 8.2, 8.3, 9.3 and 9.8 shall survive any termination of this Agreement and (ii) notwithstanding anything to the contrary contained in this Agreement (other than the provisions of Section 6.11(i)), no party shall be relieved or released from any liability or damages arising out of its willful breach of any of the provisions of this Agreement.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

8.4 Extension; Waiver.

the shareholders of PFC, there may not be, without further approval of the PFC shareholders, any extension or waiver of this Agreement or any portion of this Agreement that changes the amount or form of the consideration to be delivered to the holders of PFC Common Stock under this Agreement, other than as this Agreement contemplates. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

9.10 Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by either of the parties, whether by operation of law or otherwise, without the prior written consent of the other party.

Xxxxxxxxx, XX 00000

Ladies and Gentlemen:

F.N.B. Corporation (“FNB”) and Parkvale Financial Corporation (“PFC”) have entered into an Agreement and Plan of Merger dated as of June ___, 2011 (the “Agreement”) whereby PFC will merge with and into FNB (the “Merger”) and shareholders of PFC will receive the Merger Consideration as set forth in the Agreement, subject to the closing of the Merger. All defined terms used but not defined herein shall have the meanings ascribed thereto in the Agreement.

A condition to FNB’s obligations under the Agreement is that I execute and deliver this Letter Agreement to FNB.

Intending to be legally bound hereby, I irrevocably agree and represent as follows:

(a) I will vote or cause to be voted for approval and adoption of the Agreement and the transactions contemplated thereby all shares of PFC common stock over which I have sole voting power, and will use my best efforts to cause any shares of PFC common stock over which I share voting power to be voted for approval and adoption of the Agreement and the transactions contemplated thereby. Beneficial ownership shall have the meaning assigned to it pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended.

(b) On or prior to the record date (the “Record Date”) for the meeting of the PFC shareholders to vote on approval and adoption of the Agreement and the transactions contemplated thereby, I (i) will not offer, sell, transfer or otherwise dispose of any shares of PFC common stock over which I have sole dispositive power, and (ii) shall use my best efforts to not permit the offer, sale, transfer or other disposition of any shares of PFC common stock over which I have shared dispositive power, except to the extent that I may be permitted under law to make charitable gifts or as permitted by paragraph (g) hereof.

(c) I have beneficial ownership over the number of shares of PFC common stock, and hold stock options for the number of shares of PFC common stock, if any, set forth in Appendix A hereto.

(d) I agree that PFC shall not be bound by any attempted sale of any shares of PFC common stock over which I have sole voting and dispositive power, and PFC’s transfer agent shall be given appropriate stop transfer orders and shall not be required to register any such attempted sale, unless the sale has been effected in compliance with the terms of this Letter Agreement.

F.N.B. Corporation

_______________, 2011

(e) I agree that, if I exercise any options to purchase PFC common stock prior to the Record Date, any of the shares of PFC common stock so acquired by me, except any shares sold as part of a cashless exercise, shall be subject to clauses (a), (b) and (d) above.

(f) I represent that I have the capacity to enter into this Letter Agreement and that it is a valid and binding obligation enforceable against me in accordance with its terms, subject to bankruptcy, insolvency and other laws affecting creditors’ rights and general equitable principles.

(g) Notwithstanding anything herein to the contrary, I may transfer any or all of the shares of PFC common stock over which I have beneficial ownership to my spouse, ancestors or descendants; provided, however, that in any such case, prior to and as a condition to the effectiveness of such transfer, each person to which any of such shares or any interest in any of such shares is or may be transferred shall have executed and delivered to FNB an agreement to be bound by the terms of this Letter Agreement. In addition, I may sell, transfer or assign shares of PFC common stock to the extent and on behalf of trusts or estates of which I am not a beneficiary in order to comply with fiduciary obligations or legal requirements.

I am signing this Letter Agreement solely in my capacity as a shareholder of PFC and as an optionholder if I am an optionholder, and not in any other capacity, such as a director or officer of PFC or as a fiduciary of any trusts in which I am not a beneficiary. Notwithstanding anything herein to the contrary: (a) I make no agreement or understanding herein in any capacity other than in my capacity as a beneficial owner of PFC common stock and (b) nothing herein shall be construed to limit or affect any action or inaction by me or any of my representatives, as applicable, in serving on PFC’s Board of Directors or as an officer of PFC, in acting in my capacity as a director, officer or fiduciary of PFC or as fiduciary of any trust of which I am not a beneficiary.

This Letter Agreement shall be effective upon acceptance by FNB.

This Letter Agreement shall terminate and be of no further force and effect concurrently with, and automatically upon, the earlier to occur of (a) the consummation of the Merger, (b) the written agreement of the parties to terminate this Letter Agreement, and (c) any termination of the Agreement in accordance with its terms, except that any such termination shall be without prejudice to FNB’s rights arising out of my willful breach of any covenant or representation contained herein.

All notices and other communications in connection with this Letter Agreement shall be in writing and shall be deemed given if delivered personally, sent via facsimile, with confirmation, mailed by registered or certified mail, return receipt requested, or delivered by an express courier, with confirmation, to the parties at their addresses set forth on the signature page hereto.
