AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of August 9, 2010 (this “Agreement”), between F.N.B. CORPORATION, a Florida corporation (“FNB”), and COMM BANCORP, INC., a Pennsylvania corporation (“CBI”).

W I T N E S S E T H:

     WHEREAS, the Boards of Directors of CBI 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 in which CBI 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”);

     WHEREAS, the members of the CBI Board of Directors and Joseph P. Moore, Jr. will execute a voting agreement in the form of Exhibit B (the “Voting Agreement”); and

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

     NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties 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.

          (a) 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, CBI 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 CBI shall cease.

-1-

          (b) FNB may at any time change the method of effecting the combination and CBI shall cooperate in such efforts, including by entering into an appropriate amendment to this Agreement, to the extent such amendment only changes the method of effecting the business combination and does not substantively affect this Agreement or the rights and obligations of the parties or their respective shareholders under this Agreement; provided, however, that no such change shall (i) alter or change the amount or kind of the Merger Consideration as defined in Section 1.4(a) provided for in this Agreement, (ii) adversely affect the Tax treatment of CBI’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.

     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 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 Sections 1921 through 1932 of the PBCL and Sections 607.1101 through 607.11101 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 directors of FNB immediately prior to the Merger. 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 CBI Capital Stock.

          (a) Subject to the provisions of this Agreement, each share of common stock, $.33 par value, of CBI (“CBI Common Stock”) issued and outstanding immediately prior to the Effective Time 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 “Merger Consideration”) (i) 3.4545 shares of common stock, $.01 par value, of FNB (“FNB Common Stock”) and (ii) an amount in cash equal to $10.00, without interest. As used in this Agreement, “Stock Amount” refers to the aggregate amount of shares of FNB Common Stock to be delivered at the Closing pursuant to Section 1.4(a) and the “Cash Amount” refers to the aggregate amount of cash to be delivered at the Closing pursuant to Section 1.4(a).

-2-

          (b) At the Effective Time, the stock transfer books of CBI shall be closed as to holders of CBI Common Stock immediately prior to the Effective Time and no transfer of CBI Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, certificates representing CBI Common 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 canceled and converted into the right to receive the Merger Consideration and any dividends or distributions to which the holder of such Certificates is entitled pursuant to Section 2.2(b).

          (c) Each holder of CBI 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”)

          (d) Notwithstanding any other provision of this Agreement, each holder of CBI 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 NYSE as reported in New York Stock Exchange Composite Transactions in The Wall Street Journal (Eastern Edition) or, if not reported therein, in another mutually agreed upon authoritative source, for each of the 20 consecutive trading days ending on and including the fifth such trading day prior to the specified date rounded to the nearest ten-thousandth.

     1.5 CBI 401(K) Plan. Not later than the day immediately preceding the Closing Date, CBI agrees to cause Community Bank and Trust Company (“CBI Bank”) to (i) terminate its 401(k) Plan and (ii) return to CBI for cancellation shares of CBI Common Stock held by CBI Bank’s Trust Department for future 401(k) Plan distributions that remain at that time undistributed to 401(k) Plan participants, which shares of CBI Common Stock shall be canceled and not be subject to conversion pursuant to Section 1.4.

     1.6 CBI DRP Plan. Not later than the day immediately preceding the Closing Date, CBI agrees to terminate the Dividend Reinvestment Plan of Comm Bancorp, Inc. (the “CBI DRP Plan”) and distribute any fractions prior to the Closing Date.

     1.7 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.

-3-

     1.8 Articles of Incorporation and Bylaws of the Surviving Company. FNB’s 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. FNB’s 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.

     1.9 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.

     1.10 The Bank Merger. As soon as practicable after the execution of this Agreement, CBI and FNB shall cause CBI 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 CBI 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 upon consummation of the Bank Merger shall be the directors of FNB Bank immediately prior to the Bank Merger.

ARTICLE 2

EXCHANGE OF SHARES

     2.1 FNB to Make Merger Consideration Available. Within four business days following the Effective Time, FNB shall deposit, or shall cause to be deposited, with the Registrar and Transfer Company, (the “Exchange Agent”), for the benefit of the former shareholders of CBI Common Stock for exchange in accordance with this Article 2, (i) authority to issue book entries representing the shares of FNB Common Stock sufficient to deliver the aggregate Stock Amount, (ii) cash in an aggregate amount equal to the Cash Amount for all of the outstanding shares of CBI Common Stock, (iii) immediately available funds equal to any dividends or distributions payable in accordance with Section 2.2(b) and (iv) cash in lieu of any fractional shares (such cash and book entries for shares of FNB Common Stock, collectively being referred to as the “Exchange Fund”), to be issued pursuant to Section 1.4(a) and paid pursuant to Section 1.4(a) in exchange for outstanding shares of CBI Common Stock.

     2.2 Exchange of Shares.

          (a) After the Effective Time of the Merger, each holder of a Certificate formerly representing CBI Common Stock, other than Treasury Shares, who surrenders or has surrendered such Certificate or customary affidavits and indemnification regarding the

-4-

loss or destruction of such Certificate, together with duly executed transmittal materials to the Exchange Agent, shall, upon acceptance thereof, be entitled to (i) a book entry representing the FNB Common Stock and (ii) the cash into which the shares of CBI Common Stock shall have been converted pursuant to Section 1.4, as well as cash in lieu of any fractional share of FNB Common Stock to which such holder would otherwise be entitled, if applicable. 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, each Certificate representing CBI Common Stock shall be deemed from and after the Effective Time of the Merger to evidence only the right to receive the Merger Consideration to which it is entitled hereunder upon such surrender. FNB shall not be obligated to deliver the Merger Consideration to which any former holder of CBI Common Stock is entitled as a result of the Merger until such holder surrenders his Certificate or Certificates for exchange as provided in this Section 2.2. If any certificate for shares of FNB Common Stock, or any check representing cash 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 stamp 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.

          (b) No dividends or other distributions declared or made after the Effective Time of the Merger with respect to FNB Common Stock with a record date after the Effective Time of the Merger shall be paid to the holder of any unsurrendered Certificate with respect to the shares of FNB Common Stock represented thereby or issuable in respect thereof, and no cash payment in lieu of a fractional share shall be paid to any such holder pursuant to Section 1.4, until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, FNB shall cause the book entries to be made for the benefit of such record holder representing whole shares of FNB Common Stock issued in exchange for such Certificate and FNB shall pay to such record holder, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of FNB Common Stock to which such holder is entitled pursuant to Section 1.4 and the amount of dividends or other distributions with a record date on or after the Effective Time of the Merger theretofore paid with respect to such whole shares of FNB Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time of the Merger but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of FNB Common Stock.

          (c) All cash and shares of FNB Common Stock issued upon the surrender for exchange of shares of CBI Common Stock or the provision of customary affidavits and indemnification for lost or mutilated Certificates in accordance with the terms of this

-5-

Agreement and the letter of transmittal, including any cash paid pursuant to Section 1.4, shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of CBI Common Stock, and there shall be no further registration of transfers on the stock transfer books of FNB, after the Merger, of the shares of CBI Common Stock that were outstanding immediately prior to the Effective Time of the Merger. If, after the Effective Time of the Merger, Certificates are presented to FNB for any reason, they shall be canceled and exchanged as provided in this Agreement.

          (d) Any portion of the Exchange Fund, including any interest thereon, that remains undistributed to the shareholders of CBI following the passage of 12 months after the Effective Time of the Merger shall be delivered to FNB, upon demand, and any shareholders of CBI who have not theretofore complied with this Section 2.2 shall thereafter look only to FNB for payment of their claim for cash and for FNB Common Stock, any cash in lieu of fractional shares of FNB Common Stock and any dividends or distributions with respect to FNB Common Stock.

          (e) Neither CBI nor FNB shall be liable to any holder of shares of CBI Common Stock or FNB Common Stock, as the case may be, for such shares, and cash or dividends or distributions with respect thereto, or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

          (f) The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the shares of FNB Common Stock and cash held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such shares of FNB Common Stock for the account of the Persons entitled thereto.

     2.3 Adjustments for Dilution and Other Matters. If prior to the Effective Time of the Merger:

          (a) FNB shall declare a stock dividend or distribution on FNB Common Stock with a record date prior to the Effective Time of the Merger, or subdivide, split up, reclassify or combine FNB Common Stock, or make a distribution other than a regular quarterly cash dividend not in excess of $.20 per share, on FNB Common Stock in any security convertible into FNB Common Stock, in each case with a record date prior to the Effective Time of the Merger; or

          (b) the outstanding shares of FNB Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities, in each case as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in FNB’s capitalization other than pursuant to a business combination transaction with another bank holding company or financial services company, then a proportionate adjustment or adjustments will be made to

-6-

the Merger Consideration, which adjustment may include, as appropriate, the issuance of securities, property or cash on the same basis as that on which any of the foregoing shall have been issued or issuable to, distributed or distributable to or paid or payable to holders of FNB Common Stock generally.

     2.4 Withholding Rights. The Exchange Agent or, subsequent to the first anniversary of the Effective Time, FNB, shall be entitled to deduct and withhold from any cash portion of the Merger Consideration, any cash in lieu of fractional shares of FNB Common Stock, cash dividends or distributions payable pursuant to Section 2.2(b) and any other cash amounts otherwise payable pursuant to this Agreement to any holder of CBI Common Stock such amounts as the Exchange Agent or FNB, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment.

     “FNB Plan” means any FNB Benefit Plan other than a Multiemployer Plan.

          (a) Section 4.11(a) of the FNB Disclosure Schedule includes a complete list of all material FNB Benefit Plans and all material FNB Employment Agreements.

          (b) With respect to each FNB Plan, FNB has delivered or made available to CBI a true, correct and complete copy of: (i) each writing constituting a part of such FNB Plan, including without limitation all plan documents, employee communications, benefit schedules, trust agreements, and insurance contracts and other funding vehicles, (ii) the most recent Annual Report (Form 5500 Series) and accompanying schedule, if any, (iii) the current summary plan description and any material modifications thereto, if any (in each case, whether or not required to be furnished under ERISA), (iv) the most recent annual financial report, if any, (v) the most recent actuarial report, if any, and (vi) the most recent determination letter from the IRS, if any.

There is not now, nor do any circumstances exist that would reasonably be expected to give rise to, any requirement for the posting of security with respect to a FNB Plan or the imposition of any material lien on the assets of FNB or any of its Subsidiaries under ERISA or the Code. Section 4.11(d) of the FNB Disclosure Schedule identifies each FNB Plan that is intended to be a “qualified plan” within the meaning of Section 401(a) of the Code (“FNB Qualified Plans”).

No trust funding any FNB Plan is intended to meet the

-33-

requirements of Code Section 501(c)(9). To the knowledge of FNB, none of FNB and its 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 subject any of the FNB Plans or their related trusts, FNB, any of its Subsidiaries or any person that FNB or any of its 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 FNB Benefit Plan is a Multiemployer Plan or a Multiple Employer Plan, (ii) none of FNB and its 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 FNB and its 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 expected to result in, any Controlled Group Liability that would be a liability of FNB or any of its Subsidiaries following the Effective Time, other than such liabilities that arise solely out of, or relate solely to, the FNB Benefit Plans. Without limiting the generality of the foregoing, neither FNB nor any of its Subsidiaries, nor, to FNB’s knowledge, any of their respective ERISA Affiliates, has engaged in any transaction described in Section 4069 or Section 4204 or 4212 of ERISA.

ADDITIONAL AGREEMENTS

     6.1 Regulatory Matters.

          (a) FNB agrees to prepare and file, as soon as practicable, the Registration Statement with the SEC in connection with the issuance of FNB Common Stock in the Merger including the Proxy Statement and prospectus and other proxy solicitation materials of CBI constituting a part thereof and all related documents. CBI shall prepare and furnish to FNB such information relating to it and its directors, officers and shareholders as may be reasonably required in connection with the above referenced documents based on its knowledge of and access to the information required for said documents, and CBI, and its legal, financial and accounting advisors, shall have the right to review in advance and approve, which approval shall not be unreasonably withheld such Registration Statement prior to its filing. CBI agrees to cooperate with FNB and FNB’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and independent auditor in connection with the Registration Statement and the Proxy Statement. As long as CBI has cooperated as described above, FNB agrees to file, or cause to be filed, the Registration Statement and the Proxy Statement with the SEC as promptly as reasonably practicable. Each of CBI and FNB agrees to use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after the filing thereof. FNB also agrees to use its reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions this Agreement contemplates. After the SEC has declared the Registration Statement effective under the Securities Act, CBI shall promptly mail at its expense the Proxy Statement to its shareholders.

          (b) Each of CBI and FNB agree that none of the respective information supplied or to be supplied by it for inclusion or incorporation by reference in the Registration Statement shall, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, 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 CBI 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 CBI 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

-45-

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 CBI and/or FNB.

          (c) FNB agrees to advise CBI, 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 the amendment or supplement of the Registration Statement or for additional information.

          (d) The parties shall cooperate with each other and use their respective reasonable best efforts to promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties, Regulatory Agencies and Governmental Entities that are necessary or advisable to consummate the transactions this Agreement contemplates, including the Merger, and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such Regulatory Agencies and Governmental Entities. CBI 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 CBI 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 this Agreement contemplates. 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 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 and its Subsidiaries, including the Surviving Company after giving effect to the Merger, taken as a whole after the Effective Time (a “Materially Burdensome Regulatory Condition”). In addition, CBI 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 CBI and FNB following consummation of the Merger.

-46-

          (e) Each of FNB and CBI shall, upon request, furnish to the other all information concerning itself, its Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the Registration Statement or any other statement, filing, notice or application made by or on behalf of FNB, CBI or any of their respective Subsidiaries to any Regulatory Agency or Governmental Entity in connection with the Merger and the other transactions this Agreement contemplates.

          (f) Each of FNB and CBI shall promptly advise the other upon receiving any communication 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) CBI 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. In addition, the Chief Executive Officers of CBI and FNB shall be permitted to respond to appropriate questions about the Merger from the press. CBI and FNB shall cooperate to develop all public announcement materials and make appropriate management available at presentations related to the Merger as reasonably requested by the other party.

     6.2 Access to Information.

          (a) Upon reasonable notice and subject to applicable laws relating to the exchange of information, each of CBI and FNB shall, and shall cause each of its Subsidiaries to, afford to the officers, employees, accountants, counsel and other representatives of the other, reasonable access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records, and, during such period, the parties shall, and shall cause its Subsidiaries to, make available to the other party all other information concerning its business, properties and personnel as the other may reasonably request. CBI 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 CBI 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

-47-

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 CBI 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 CBI Shareholder Approval. CBI 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 “CBI 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. Subject to Section 6.11, the Board of Directors of CBI shall recommend approval and adoption of this Agreement, the Merger and the other transactions this Agreement contemplates, by CBI’s shareholders and shall include such recommendation in the Proxy Statement (the “CBI Recommendation”). Without limiting the generality of the foregoing, CBI’s obligations pursuant to the first sentence of this Section 6.3 shall not be affected by the commencement, public proposal, public disclosure or communication to CBI of any Acquisition Proposal, as defined in Section 6.11(e). Notwithstanding the foregoing, if this Agreement is terminated pursuant to Section 8.1, CBI’s obligations pursuant to the first sentence of this Section 6.3 shall terminate.

     6.4 Commercially Reasonable Efforts; Cooperation. Each of CBI and FNB agrees to exercise good faith and use its commercially reasonable best efforts to satisfy the various covenants and conditions to Closing in this Agreement, and to consummate the transactions this Agreement contemplates as promptly as possible.

     6.5 NYSE Approval. FNB shall cause the shares of FNB Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

     6.6 Benefit Plans.

          (a) As soon as administratively practicable after the Effective Time, FNB shall take all reasonable action so that employees of CBI and its Subsidiaries shall be entitled to participate in each employee benefit plan, program or arrangement of FNB of general

-48-

applicability with the exception of FNB’s defined benefit pension plan (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 CBI and its 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 CBI and its 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 CBI under any discretionary equity compensation plan of FNB. FNB shall cause each FNB Plans in which employees of CBI and its Subsidiaries are eligible to participate to recognize, for purposes of determining eligibility to participate in, the vesting of benefits under the FNB Plans, the service of such employees with CBI and its Subsidiaries to the same extent as such service was credited for such purpose by CBI, 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 CBI and its Subsidiaries that correspond to FNB Plans until employees of CBI and its Subsidiaries are included in such FNB Plans, nothing in this Agreement shall limit the ability of FNB to amend or terminate any of CBI’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 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 CBI and its Subsidiaries and current and former directors of CBI and its 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 CBI that are set forth on Schedule 6.6(b) of the CBI Disclosure Schedule, subject to the receipt of any necessary approval from any Governmental Entity. The severance or termination payments that are payable pursuant to such agreements, plans or policies of CBI are set forth on Schedule 6.6(b) of the CBI 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 CBI or its Subsidiaries who are terminated for other than cause, severance as set forth on Schedule 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 CBI and its Subsidiaries become eligible to participate in a medical, dental or health plan of FNB or its Subsidiaries, FNB shall 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 FNB and (ii) 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

-49-

employee or dependent had satisfied any similar limitation or requirement under an analogous Benefit Plan prior to the Effective Time.

          (d) Immediately prior to the Effective Time, CBI shall, at the written request of FNB, freeze or terminate such of the CBI Benefit Plans as is requested by FNB.

          (e) By August 31, 2010, the five principal executive officers of CBI identified in Schedule 6.6(e) shall deliver to CBI and FNB a supplemental letter pursuant to which such officer agrees to continue in the employment of CBI for the respective period of time set forth in Schedule 6.6(e) and, were such officer to leave the employment of CBI prior to the expiration of such period, such officer shall not be entitled to receive any severance or change of control benefits under such agreement.

     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 any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of CBI or any of its Subsidiaries or who is or was serving at the request of CBI or any of its 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 CBI or any of its Subsidiaries or was serving at the request of CBI or any of its 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 CBI Articles, the CBI Bylaws and any agreement set forth in Section 6.7 of the CBI 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 CBI Articles or the CBI 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

-50-

determination required to be made with respect to whether an Indemnified Person’s conduct complies with the standards set forth under the PBCL, the CBI Articles or the CBI 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 CBI or its Subsidiaries, including pursuant to the respective organizational documents of CBI, or their respective Subsidiaries, under the PBCL or otherwise.

          (c) Prior to the Effective Time, FNB shall obtain at the expense of CBI, 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 CBI’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 CBI or single premium tail coverage with policy limits equal to CBI’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 CBI 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 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 CBI’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.
