AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of November 8, 2007 (this “Agreement”), between F.N.B. CORPORATION, a Florida corporation (“FNB “) and OMEGA FINANCIAL CORPORATION, a Pennsylvania corporation (“Omega”).

W I T N E S S E T H:

WHEREAS, the Boards of Directors of Omega 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 Omega 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 Omega Board of Directors have executed a voting agreement of even date herewith in the form of Exhibit C (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 I

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), Omega 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 Omega shall cease.

-1-

(b) FNB may at any time change the method of effecting the combination and Omega 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 hereunder); 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 Omega’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 contemplated by this Agreement.

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) 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 (i) the directors of FNB immediately prior to the Merger and (ii) three current independent members of Omega’s Board of Directors (the “Omega Designees”) as are mutually agreed by FNB and Omega. 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 Omega Capital Stock.

(a) Subject to the provisions of this Agreement, each share of common stock, $5.00 par value, of Omega (“Omega Common Stock”) issued and outstanding immediately prior to the Effective Time, other than Treasury Shares (as defined in Section 1.4(b)) 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”) 2.022 shares (the “Exchange Ratio”) of common stock, $.01 par value, of FNB (“FNB Common Stock”).

-2-

(b) 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 Omega Common Stock held by Omega or any of its 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.

(c) At the Effective Time, the stock transfer books of Omega shall be closed as to holders of Omega Common Stock immediately prior to the Effective Time and no transfer of Omega Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, certificates representing Omega Common Stock (“Certificates”) are properly presented in accordance with Section 2.2 of this Agreement to the Exchange Agent (as defined in Section 2.2(a)), such Certificates shall be canceled and exchanged for certificates representing the number of whole shares of FNB Common Stock into which the Omega Common Stock represented thereby was converted in the Merger, plus 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).

(d) Each holder of Omega 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 Stock Purchase Plan (the “DRSP Plan”). Each Omega shareholder electing to enroll in the DRSP Plan shall be issued a certificate representing the number of whole shares of FNB Common Stock received in the Merger, and any future dividends will be reinvested in accordance with the DRSP Plan.

(e) Notwithstanding any other provision of this Agreement, each holder of Omega 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.

-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 Omega Equity and Equity-Based Awards.

(a) Omega Stock Options. Effective as of the Effective Time, each then outstanding option to purchase shares of Omega Common Stock (each an “Omega Stock Option”), pursuant to the equity-based compensation plans identified on Section 3.11(a) of the Omega Disclosure Schedule (as defined in Article III) (the “Omega Stock Plans”) and the award agreements evidencing the grants thereunder, granted to any current or former employee or director of, or consultant to, Omega or any of its Subsidiaries (as defined in Section 3.1(b)) shall at the Effective Time cease to represent a right to acquire shares of Omega Common Stock and shall be converted automatically into an option to acquire shares of FNB Common Stock and each option to acquire shares of Omega Common Stock that prior to the Effective Time is fully vested and exercisable, shall continue as a fully vested and exercisable option of FNB on the terms hereinafter set forth. FNB shall assume each such Omega Stock Option in accordance with the terms of the relevant Omega 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 shall be substituted for Omega and the committee of the Board of Directors of Omega, including, if applicable, the entire Board of Directors of Omega, administering such Omega Stock Plan, (ii) each Omega 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 Omega Stock Option shall be equal to the number of shares of Omega Common Stock subject to such Omega 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 Omega Stock Option prior to the Effective Time divided by the Exchange Ratio. Notwithstanding clauses (iii) and (iv) of the preceding sentence, each Omega Stock Option that is an “incentive stock option” shall be adjusted as required by Section 424 of the Code, and the 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 Omega agree to take all 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 Omega Stock Option that has been assumed by FNB (the “Assumed Stock Options”) a document evidencing the conversion and assumption of such Omega Stock Option by FNB pursuant to this Section 1.6(a).

(b) Omega Restricted Stock Units. Effective immediately prior to the Effective Time, each then outstanding restricted stock unit (each an “Omega RSU”), pursuant

-4-

to the Omega Stock Plans and the award agreements evidencing the grants thereunder, granted to any current or former employee of Omega or any of its Subsidiaries shall become vested in full. At the Effective Time, each holder of an Omega RSU shall be entitled to receive a number of shares of FNB Common Stock equal to the Exchange Ratio multiplied by the total number of shares of Omega Common Stock subject to such Omega RSU.

(c) Omega Employee Stock Ownership Plan. If requested by FNB, Omega agrees that its Employee Stock Ownership Plan (the “ESOP”) shall terminate as of a date not later than March 31, 2008 and, in connection therewith, repay all indebtedness of the ESOP. Appropriate distributions of all of the assets held by the ESOP will be made to the participants in the ESOP as soon as reasonably practicable thereafter in accordance with the provisions of the ESOP and applicable law.

(d) Omega 401(k) Plan. Not later than the day prior to the Closing Date, Omega agrees to terminate its Section 401(k) Plan.

(e) Reservation of Shares. FNB has taken all corporate action necessary to reserve for issuance a sufficient number of shares of FNB Common Stock issuable upon the exercise of the Assumed Stock Options. As soon as practicable following the Closing (as defined in Section 9.1), FNB shall file a registration statement on an appropriate form or a post-effective amendment to a previously filed registration statement under the Securities Act of 1933, as amended (the “Securities Act”) with respect to the issuance of the shares of FNB Common Stock subject to the Assumed Stock Options and shall use its best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such equity awards remain outstanding.

1.7 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.

1.8 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 Omega 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, Omega and FNB shall cause Omega Bank (“Omega Bank”) and First National Bank of

-5-

Pennsylvania (“FNB Bank”) to enter into a bank merger agreement, the form of which is attached hereto as Exhibit A (the “Bank Merger Agreement”), that provides for the merger of Omega 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 (the “FNB Bank Board”) upon consummation of the Bank Merger shall be the directors of FNB Bank immediately prior to the Bank Merger plus the four Omega Bank Designees as defined in Section 6.15(b).

ARTICLE II

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 the Exchange Agent, for the benefit of the holders of Certificates, for exchange in accordance with this Article II, (i) certificates representing the aggregate number of shares of FNB Common Stock issuable pursuant to this Agreement in exchange for shares of Omega Common Stock outstanding immediately prior to the Effective Time of the Merger, (ii) immediately available funds equal to any dividends or distributions payable in accordance with Section 2.2(b) and (iii) cash in lieu of any fractional shares (such cash and certificates for shares of FNB Common Stock, collectively being referred to as the “Exchange Fund”), to be issued pursuant to Section 1.4 and paid pursuant to Section 1.4 in exchange for outstanding shares of Omega Common Stock.

2.2 Exchange of Shares.

(a) As soon as practicable after the Effective Time, Registrar and Transfer Company (the “Exchange Agent”) shall mail to each holder of record of Omega Common Stock a letter of transmittal in customary form as prepared by FNB and reasonably acceptable to Omega 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 Omega 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 Omega Common 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 a certificate representing FNB Common Stock into which the shares of Omega Common Stock shall have been converted pursuant to Section 1.4, as well as any cash in lieu

-6-

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, each Certificate representing Omega Common Stock shall be deemed from and after the Effective Time of the Merger to evidence only the right to receive the Merger Consideration any cash in lieu of fractional shares into which the shares of Omega 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). 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 Omega 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 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.

(b) Following surrender of any such Certificate, there shall be paid to the record holder of the Certificates representing whole shares of FNB Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any dividends or distributions with a record date prior to the Effective Date which have been declared by Omega in respect of shares of Omega Common Stock after the date of this Agreement in accordance with the terms of this Agreement and which remain unpaid at the Effective Time, (ii) 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 after the Effective Time of the Merger and which theretofore had become payable with respect to such whole shares of FNB Common Stock, and (iii) 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. After the date of this Agreement, Omega shall coordinate with FNB the declaration of any dividends in respect of Omega Common Stock as provided in Section 6.11.

(c) After the Effective Time, there shall be no transfers on the stock transfer books of Omega of the shares of Omega Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of Omega Common

-7-

Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates are presented to FNB for any reason, they shall be canceled and exchanged as provided in this Agreement. All shares of FNB Common Stock and cash in lieu of fractional shares and/or declared but unpaid dividends issued upon the surrender for exchange of shares of Omega Common Stock or the provision of customary affidavits and indemnification for lost or mutilated Certificates in accordance with the terms hereof and the letter of transmittal, shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Omega Common Stock.

(d) Any portion of the Exchange Fund, including any interest thereon, that remains undistributed to the shareholders of Omega following the passage of 12 months after the Effective Time of the Merger shall be delivered to FNB, upon demand, and any shareholders of Omega who have not theretofore complied with this Section 2.3 shall thereafter look only to FNB for payment of their claim for FNB Common Stock, any cash in lieu of fractional shares of FNB Common Stock and any unpaid dividends or distributions payable in accordance with Section 2.2(b).

(e) Neither Omega nor FNB shall be liable to any holder of shares of Omega Common Stock or FNB Common Stock, as the case may be, for such shares, 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 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.

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 an Omega Plan or the imposition of any material lien on the assets of Omega or any of its Subsidiaries under ERISA or the Code. Section 3.11(d) of the Omega Disclosure Schedule identifies each Omega Plan that is intended to be a “qualified plan” within the meaning of Section 401(a) of the Code (“Omega Qualified Plans”). The IRS has issued a favorable determination letter with respect to each Omega Qualified Plan and the related trust that has not been revoked or Omega is entitled to rely on a favorable opinion issued by the IRS, and, to the knowledge of Omega, there are no existing circumstances and no events have occurred that would reasonably be expected to adversely affect the qualified status of any Omega Qualified Plan or the related trust. No trust funding any Omega Plan is intended to meet the requirements of Code Section 501(c)(9). To the knowledge of Omega, none of Omega 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 Omega Plans or their related trusts, Omega, any of its Subsidiaries or any person that Omega 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.

(e) With respect to each Omega Plan that is subject to Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code, (i) there does not exist any accumulated funding deficiency within the meaning of Section 412 of the Code or Section 302 of ERISA, whether or not waived, and, (ii) (A) the fair market value of the assets of such Omega Plan equals or exceeds the actuarial present value of all accrued benefits under such Omega Plan (whether or not vested) on a termination basis; (B) no reportable event within the meaning of Section 4043(c) of ERISA for which the 30-day notice requirement has not been waived has occurred; (C) all premiums to the Pension Benefit Guaranty Corporation (the “PBGC”) have been timely paid in full; (D) no liability (other than for premiums to the PBGC) under Title IV of ERISA has been or would reasonably be expected to be incurred by Omega or any of its Subsidiaries; and (E) the PBGC has not instituted proceedings to terminate any such Omega Plan and, to Omega’s knowledge, no condition exists that presents a risk that such proceedings will be instituted or which would reasonably be expected to constitute grounds under Section 4042 of ERISA for the termination of, or the appointment of a trustee to administer, any such Omega Plan, except as would not have a Material Adverse Effect, individually or in the aggregate, in the case of clauses (A), (B), (C), (D) and (E).

-20-

(f) (i) No Omega 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 Omega 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 Omega 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 Omega or any of its Subsidiaries following the Effective Time, other than such liabilities that arise solely out of, or relate solely to, the Omega Benefit Plans. Without limiting the generality of the foregoing, neither Omega nor any of its Subsidiaries, nor, to Omega’s knowledge, any of their respective ERISA Affiliates, has engaged in any transaction described in Section 4069 or Section 4204 or 4212 of ERISA.

(g) Omega and its 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 Omega and its Subsidiaries.

(h) Neither the execution nor the delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement 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 Omega or any of its Subsidiaries, (ii) increase the amount or value of any benefit or compensation 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 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 Section 409A of the Code.

(i) No labor organization or group of employees of Omega or any of its Subsidiaries has made a pending demand for recognition or certification, and there are no representation or certification proceedings or petitions seeking a representation proceeding presently pending or, to Omega’s knowledge, threatened to be brought or filed, with the National Labor Relations Board or any other labor relations tribunal or authority. Each of Omega and its Subsidiaries is in material compliance with all applicable laws respecting employment and employment practices, terms and conditions of employment, wages and hours and occupational safety and health.

3.12 SEC Reports. Omega has previously made available to FNB an accurate and complete copy of each final registration statement, prospectus, report, schedule and definitive proxy statement filed since January 1, 2005 by Omega with the SEC pursuant to the

-21-

Securities Act or the Exchange Act (the “Omega Reports”), on and prior to the date of this Agreement and no such Omega Report as of the date of such Omega Report contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances in which they were made, not misleading, except that information as of a later date (but before the date of this Agreement) shall be deemed to modify information as of an earlier date. Since January 1, 2005, as of their respective dates, all Omega Reports filed under the Securities Act and the Exchange Act complied as to form in all material respects with the published rules and regulations of the SEC with respect thereto.

3.13 Compliance with Applicable Law.

3.14 Contracts. Except for matters that have not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Omega and its Subsidiaries taken as a whole, (i) none of Omega nor any of its Subsidiaries is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect under any material contract, lease, license or other agreement or instrument, (ii) to the knowledge of Omega, none of the other parties to any such material contract, lease, license or other agreement or instrument is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect thereunder and (iii) neither Omega nor any of its Subsidiaries has received any written notice of the intention of any party to terminate or cancel any such material contract, lease, license or other agreement or instrument whether as a termination or cancellation for convenience or for default of Omega or any of its Subsidiaries.

Neither Omega nor any of its Subsidiaries is subject to any cease-and-desist or other order or enforcement action issued by, or is a party to any written agreement, consent agreement or memorandum of understanding with, or is a party to any commitment letter or similar undertaking to, or is subject to any order or directive by, or has been ordered to pay any civil money penalty by, or has been since January 1, 2005, a recipient of any supervisory letter from, or since January 1, 2005, has

To the knowledge of Omega, there has not been any event or occurrence since January 1, 2005 that could reasonably be expected to result in a determination that Omega Bank is not “well capitalized” and “well managed” as a matter of U.S. federal banking law. Omega Bank has at least a “satisfactory” rating under the U.S. Community Reinvestment Act.

(c) The Owned Properties and the properties leased pursuant to the Leases (the “Leased Properties”) constitute all of the real estate on which Omega and its Subsidiaries maintain their facilities or conduct their business as of the date of this Agreement, except for locations the loss of which would not result in a Material Adverse Effect on Omega and its Subsidiaries taken as a whole.

The December 31, 2006 consolidated balance sheet of FNB (including the related notes, where applicable) fairly presents in all material respects the consolidated financial position of FNB and its Subsidiaries as of the date thereof, and the other financial statements referred to in this Section 4.6 (including the related notes, where applicable) fairly present in all material respects the results of the consolidated operations, cash flows and changes in shareholders’ equity and consolidated financial position of FNB and its Subsidiaries for the respective fiscal periods or as of the respective dates therein set forth, subject to normal year-end audit adjustments in amounts consistent with past experience in the case of unaudited statements; each of such statements (including the related notes, where applicable) complies in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto; and each of such statements (including the related notes, where applicable) has been prepared in all material respects in accordance with GAAP consistently applied during the periods involved, except, in each case, as indicated in such statements or in the notes thereto.

Since December 31, 2006, except as publicly disclosed in the Forms 10-K, 10-Q and 8-K comprising the FNB Reports (as defined in Section 4.12) filed prior to the date of this Agreement (i) FNB and the FNB Subsidiaries have (except in connection with the negotiation and execution and delivery of this Agreement) carried on their respective businesses in all material respects in the ordinary course consistent with past practice and (ii) there has not been any Material Adverse Effect with respect to FNB.

4.9 Legal Proceedings.

(a) There is no pending, or, to FNB’s knowledge, threatened, litigation, action, suit, proceeding, investigation or arbitration by any Person or Governmental Entity that is material to FNB and its Subsidiaries, taken as a whole, in each case with respect to FNB or any of its Subsidiaries or any of their respective properties or permits, licenses or authorizations.

4.10 Taxes and Tax Returns. Each of FNB and its Subsidiaries has duly and timely filed (including all applicable extensions) all Tax Returns required to be filed by it on or prior to the date of this Agreement (all such Tax Returns being accurate and complete in all material respects), has timely paid or withheld and timely remitted all Taxes shown thereon as arising and has duly and timely paid or withheld and timely remitted all Taxes (whether or not shown on any Tax Return) that are due and payable or claimed to be due from it by a Governmental Entity other than Taxes that (i) are being contested in good faith, which have not been finally determined, and (ii) have been adequately reserved against in accordance with GAAP on FNB’s most recent consolidated financial statements. All required estimated Tax payments sufficient to avoid any underpayment penalties or interest have been made by or on behalf of each of FNB and its Subsidiaries. Neither FNB nor any of its Subsidiaries has granted any extension or waiver of the limitation period for the assessment or collection of Tax that remains in effect. There are no disputes, audits, examinations or proceedings in

-32-

progress or pending (including any notice received of an intent to conduct an audit or examination), or claims asserted, for Taxes upon FNB or any of its Subsidiaries. No claim has been made by a Governmental Entity in a jurisdiction where the FNB or any of its Subsidiaries has not filed Tax Returns such that FNB or any of its Subsidiaries is or may be subject to taxation by that jurisdiction. All deficiencies asserted or assessments made as a result of any examinations by any Governmental Entity of the Tax Returns of, or including, FNB or any of its Subsidiaries have been fully paid. No issue has been raised by a Governmental Entity in any prior examination or audit of each of FNB and its Subsidiaries which, by application of the same or similar principles, could reasonably be expected to result in a proposed deficiency in respect of such Governmental Entity for any subsequent taxable period. There are no Liens for Taxes (other than statutory liens for Taxes not yet due and payable) upon any of the assets of FNB or any of its Subsidiaries. Neither FNB nor any of its Subsidiaries is a party to or is bound by any Tax sharing, allocation or indemnification agreement or arrangement (other than such an agreement or arrangement exclusively between or among FNB and its Subsidiaries). Neither FNB nor any of its Subsidiaries (A) has been a member of an affiliated group filing a consolidated federal income Tax Return (other than a group the common parent of which was FNB) or (B) has any liability for the Taxes of any Person (other than FNB or any of its Subsidiaries) under Treas. Reg. §1.1502-6 (or any similar provision of state, local or foreign law), or as a transferee or successor, by contract or otherwise. Neither FNB nor any of its Subsidiaries has been, within the past two years or otherwise as part of a “plan (or series of related transactions)” (within the meaning of Section 355(e) of the Code) of which the Merger is also a part, or a “distributing corporation” or a “controlled corporation” (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock intended to qualify for tax-free treatment under Section 355 of the Code. No share of FNB Common Stock is owned by a Subsidiary of FNB. FNB is not and has not been a “United States real property holding company” within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code. Neither FNB, its Subsidiaries nor any other Person on their behalf has executed or entered into any written agreement with, or obtained or applied for any written consents or written clearances or any other Tax rulings from, nor has there been any written agreement executed or entered into on behalf of any of them with any Taxing Authority, relating to Taxes, including any IRS private letter rulings or comparable rulings of any Taxing Authority and closing agreements pursuant to Section 7121 of the Code or any predecessor provision thereof or any similar provision of any applicable law, which rulings or agreements would have a continuing effect after the Effective Time. Neither FNB nor any of its Subsidiaries has engaged in a “reportable transaction,” as set forth in Treas. Reg. §1.6011-4(b), or any transaction that is the same as or substantially similar to one of the types of transactions that the IRS has determined to be a tax avoidance transaction and identified by notice, regulation or other form of published guidance as a “listed transaction,” as set forth in Treas. Reg. §1.6011-4(b)(2). Omega has received complete copies of (i) all federal, state, local and foreign income or franchise Tax Returns of FNB and its Subsidiaries relating to the taxable periods beginning January 1, 2004 or later and (ii) any audit report issued within the last three years

-33-

relating to any Taxes due from or with respect to FNB or its Subsidiaries. Neither FNB, nor any of its Subsidiaries will be required to include any item of material income in, or exclude any material item of deduction from, taxable income for any taxable period (or portion thereof) ending after the Closing Date as a result of any (i) change in method of accounting for a taxable period ending on or prior to the Closing Date, (ii) installment sale or open transaction disposition made on or prior to the Effective Time, (iii) prepaid amount received on or prior to the Closing Date or (iv) deferred intercompany gain or any excess loss account of FNB or any of its Subsidiaries for periods or portions of periods described in Treasury Regulations under Section 1502 of the Code (or any corresponding or similar provision of state, local or foreign law) for periods (or portions thereof) ending on or before the Closing Date.

4.11 Employee Benefits. For purposes hereof, the following terms shall have the following meaning:

“FNB Benefit Plan” means any material employee benefit plan, program, policy, practice, or other arrangement providing benefits to any current or former employee, officer or director of FNB or any of its Subsidiaries or any beneficiary or dependent thereof that is sponsored or maintained by FNB or any of its Subsidiaries or to which FNB or any of its Subsidiaries contributes or is obligated to contribute, whether or not written, including without limitation any employee welfare benefit plan within the meaning of Section 3(1) of ERISA, any employee pension benefit plan within the meaning of Section 3(2) of ERISA (whether or not such plan is subject to ERISA) and any bonus, incentive, deferred compensation, vacation, stock purchase, stock option, severance, employment, change of control or fringe benefit plan, program or policy.

“FNB Employment Agreement” means a written contract, offer letter or agreement of FNB or any of its Subsidiaries with or addressed to any individual who is rendering or has rendered services thereto as an employee pursuant to which FNB or any of its Subsidiaries has any actual or contingent liability or obligation to provide compensation and/or benefits in consideration for past, present or future services.

“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 Omega 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,

-34-

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. FNB has delivered or made available to Omega a true, correct and complete copy of each material FNB Employment Agreement.

(c) All material contributions required to be made to any FNB Plan by applicable law or regulation or by any plan document or other contractual undertaking, and all material premiums due or payable with respect to insurance policies funding any FNB Plan, for any period through the date hereof have been timely made or paid in full or, to the extent not required to be made or paid on or before the date hereof, have been fully reflected on the financial statements to the extent required by GAAP. Each FNB Benefit Plan that is an employee welfare benefit plan under Section 3(1) of ERISA either (i) is funded through an insurance company contract and is not a “welfare benefit fund” within the meaning of Section 419 of the Code or (ii) is unfunded.

(d) With respect to each FNB Plan, FNB and its Subsidiaries have complied, and are now in compliance, in all material respects, with all provisions of ERISA, the Code and all laws and regulations applicable to such FNB Plans. Each FNB Plan has been administered in all material respects in accordance with its terms. 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”). The IRS has issued a favorable determination letter with respect to each Qualified Plan and the related trust that has not been revoked or FNB is entitled to rely on a favorable opinion issued by the IRS, and, to the knowledge of FNB, there are no existing circumstances and no events have occurred that would reasonably be expected to adversely affect the qualified status of any FNB Qualified Plan or the related trust. No trust funding any FNB Plan is intended to meet the 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.

(e) With respect to each FNB Plan that is subject to Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code, (i) there does not exist any accumulated funding deficiency within the meaning of Section 412 of the Code or Section 302 of ERISA, whether or not waived, and, (ii) except as would not have, individually or in the aggregate, a Material Adverse Effect: (A) the fair market value of the assets of such FNB Plan equals or exceeds the

-35-

actuarial present value of all accrued benefits under such FNB Plan (whether or not vested) on a termination basis; (B) no reportable event within the meaning of Section 4043(c) of ERISA for which the 30-day notice requirement has not been waived has occurred; (C) all premiums to the PBGC have been timely paid in full; (D) no liability (other than for premiums to the PBGC) under Title IV of ERISA has been or would reasonably be expected to be incurred by FNB or any of its Subsidiaries; and (E) the PBGC has not instituted proceedings to terminate any such FNB Plan and, to FNB’s knowledge, no condition exists that presents a risk that such proceedings will be instituted or which would reasonably be expected to constitute grounds under Section 4042 of ERISA for the termination of, or the appointment of a trustee to administer, any such FNB Plan.

(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.

(g) FNB and its 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 FNB and its Subsidiaries.

(h) Neither the execution nor the delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement 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 FNB or any of its Subsidiaries, (ii) increase the amount or value of any benefit or compensation 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 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 Section 409A of the Code.

(i) No labor organization or group of employees of FNB or any of its Subsidiaries has made a pending demand for recognition or certification, and there are no representation or certification proceedings or petitions seeking a representation proceeding

-36-

presently pending or, to FNB’s knowledge, threatened to be brought or filed, with the National Labor Relations Board or any other labor relations tribunal or authority. Each of FNB and its Subsidiaries is in material compliance with all applicable laws and collective bargaining agreements respecting employment and employment practices, terms and conditions of employment, wages and hours and occupational safety and health.

4.12 SEC Reports. FNB has previously made available to Omega an accurate and complete copy of each final registration statement, prospectus, report, schedule and definitive proxy statement filed since January 1, 2005 by FNB with the SEC pursuant to the Securities Act or the Exchange Act (the “FNB Reports”) and prior to the date of this Agreement, as of the date of such FNB Report, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances in which they were made, not misleading, except that information as of a later date (but before the date of this Agreement) shall be deemed to modify information as of an earlier date. Since January 1, 2005, as of their respective dates, all FNB Reports filed under the Securities Act and the Exchange Act complied as to form in all material respects with the published rules and regulations of the SEC with respect thereto.

4.13 Compliance with Applicable Law. FNB and each of its Subsidiaries hold all licenses, franchises, permits and authorizations necessary for the lawful conduct of their respective businesses under and pursuant to each, and since January 1, 2005, have complied in all respects with and are not in default in any respect under any applicable law, statute, order, rule, regulation, policy or guideline of any Governmental Entity relating to FNB or any of its Subsidiaries (including the Equal Credit Opportunity Act, the Fair Housing Act, the Community Reinvestment Act, the Home Mortgage Disclosure Act, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorist (USA Patriot) Act of 2001, the Bank Secrecy Act and applicable limits on loans to one borrower), except where the failure to hold such license, franchise, permit or authorization or such noncompliance or default is not reasonably likely to, either individually or in the aggregate, have a Material Adverse Effect on FNB.

4.14 Contracts. Except for matters that have not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on FNB and its Subsidiaries taken as a whole, (i) none of FNB nor any of its Subsidiaries is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect under any material contract, lease, license or other agreement or instrument, (ii) to the knowledge of FNB, none of the other parties to any such material contract, lease, license or other agreement or instrument is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect thereunder and (iii) neither FNB nor any of its Subsidiaries has received any written notice of the intention of any party to terminate or

-37-

cancel any such material contract, lease, license or other agreement or instrument whether as a termination or cancellation for convenience or for default of FNB or any of its Subsidiaries.

4.15 Agreements with Regulatory Agencies. Neither FNB nor any of its Subsidiaries is subject to any cease-and-desist or other order or enforcement action issued by, or is a party to any written agreement, consent agreement or memorandum of understanding with, or is a party to any commitment letter or similar undertaking to, or is subject to any order or directive by, or has been since January 1, 2005, a recipient of any supervisory letter from, or has been ordered to pay any civil money penalty by, or since January 1, 2005, has adopted any policies, procedures or board resolutions at the request or suggestion of any Regulatory Agency or other Governmental Entity that currently restricts in any material respect the conduct of its business or that in any material manner relates to its capital adequacy, its ability to pay dividends, its credit or risk management policies, its management or its business, other than those of general application that apply to similarly situated financial holding companies or their Subsidiaries (each item in this sentence, whether or not set forth in the FNB Disclosure Schedule, a “FNB Regulatory Agreement”), nor has FNB or any of its Subsidiaries been advised since January 1, 2005, by any Regulatory Agency or other Governmental Entity that it is considering issuing, initiating, ordering or requesting any such FNB Regulatory Agreement. To the knowledge of FNB, there has not been any event or occurrence since January 1, 2005 that could reasonably be expected to result in a determination that any such bank Subsidiary is not “well capitalized” and “well managed” as a matter of U.S. federal banking law. Each bank Subsidiary of FNB has at least a “satisfactory” rating under the U.S. Community Reinvestment Act.

4.16 Undisclosed Liabilities. Except for (i) those liabilities that are reflected or reserved against on the consolidated balance sheet of FNB included in the FNB 10-Q (including any notes thereto), (ii) liabilities incurred in connection with this Agreement and the transactions contemplated thereby and (iii) liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2007, since September 30, 2007, neither FNB nor any of its Subsidiaries has incurred any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due) that, either individually or in the aggregate, has had or is reasonably likely to have, a Material Adverse Effect on FNB.

4.17 Environmental Liability.

(a) To FNB’s Knowledge, (A) FNB and its Subsidiaries are in material compliance with applicable environmental laws; (B) no real property, including buildings or other structures, currently or formerly owned or operated by FNB or any of its Subsidiaries, or any property in which FNB or any of its Subsidiaries has held a security interest, Lien or a fiduciary or management role (“FNB Loan Property”), has been contaminated with, or has had any release of, any Hazardous Substance except in material compliance with Environmental Laws; (C) neither FNB nor any of its Subsidiaries could be deemed the owner

-38-

(b) There are no legal, administrative, arbitral or other proceedings, claims, actions, causes of action, private environmental investigations or remediation activities or governmental investigations of any nature seeking to impose, or that are reasonably likely to result in the imposition, on FNB of any liability or obligation arising under common law or under any local, state or federal environmental statute, regulation or ordinance including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, pending or threatened against FNB, which liability or obligation is reasonably likely to have, either individually or in the aggregate, a Material Adverse Effect on FNB. To the knowledge of FNB, there is no reasonable basis for any such proceeding, claim, action or governmental investigation that would impose any liability or obligation that would be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect on FNB. FNB is not subject to any agreement, order, judgment, decree, letter or memorandum by or with any Governmental Entity or third party imposing any liability or obligation with respect to the foregoing that is reasonably likely to have, either individually or in the aggregate, a Material Adverse Effect on FNB.

-39-

ARTICLE VI

ADDITIONAL AGREEMENTS

6.1 Regulatory Matters.

(a) FNB agrees to prepare the Registration Statement to be filed by FNB with the SEC in connection with the issuance of FNB Common Stock in the Merger including the Joint Proxy Statement and prospectus and other proxy solicitation materials of Omega and FNB constituting a part thereof and all related documents. Omega 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 Omega, 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. Omega 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 Joint Proxy Statement. As long as Omega has cooperated as described above, FNB agrees to file, or cause to be filed, the Registration Statement and the Joint Proxy Statement with the SEC as promptly as reasonably practicable. Each of Omega 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 contemplated by this Agreement. After the Registration Statement is declared effective under the Securities Act, Omega and FNB shall each promptly mail at its expense the Joint Proxy Statement to its respective shareholders.

(b) Each of Omega and FNB agree that none of the 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 therein or necessary to make the statements therein not misleading. Each of Omega and FNB agree that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Joint 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 therein or necessary to make the statements therein not misleading. Each of Omega 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 Joint 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 therein not false or

-47-

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 Omega and/or FNB.

(c) FNB agrees to advise Omega, 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 contemplated by this Agreement (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. Omega 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 Omega 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 contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated by this Agreement. 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, Omega 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

-48-

necessary or advisable to effect any mergers and/or consolidations of Subsidiaries of Omega and FNB following consummation of the Merger.

(e) Each of FNB and Omega 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 Joint Proxy Statement, the Registration Statement or any other statement, filing, notice or application made by or on behalf of FNB, Omega or any of their respective Subsidiaries to any Regulatory Agency or Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement.

(f) Each of FNB and Omega 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 contemplated by this Agreement 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) Press Releases. Omega 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 Omega and FNB shall be permitted to respond to appropriate questions about the Merger from the press.

Omega shall, and shall cause each of its Subsidiaries to, provide to FNB a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of

-49-

federal securities laws or federal or state banking laws other than reports or documents that such party is not permitted to disclose under applicable law. Neither Omega 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.

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

(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 Shareholder Approval.

(a) Omega 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 “Omega Shareholder Meeting”), and shall use its reasonable best efforts to cause its meeting to occur as soon as reasonably practicable. Subject to Section 6.13, the Board of Directors of Omega shall recommend approval and adoption of this Agreement, the Merger and the other transactions contemplated hereby, by Omega’s shareholders and shall include such recommendation in the Joint Proxy Statement (the “Omega Recommendation”). Without limiting the generality of the foregoing, Omega’s obligations pursuant to the first sentence of this Section 6.3(a) shall not be affected by the commencement, public proposal, public disclosure or communication to Omega of any Acquisition Proposal (as defined in Section 6.13(e)). Notwithstanding the foregoing, if this Agreement is terminated pursuant to Section 8.1, Omega’s obligations pursuant to the first sentence of this Section 6.3(a) shall terminate.

(b) FNB 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 “FNB Shareholder Meeting”), and shall use its reasonable best efforts to cause its meeting to occur as soon as reasonably practicable. The Board of Directors of FNB shall recommend that FNB’s shareholders vote in favor of approval and adoption of this Agreement, the Merger, including the issuance of the shares of FNB Common Stock in connection therewith and the other transactions contemplated hereby (the “FNB Proposal”). FNB shall include such recommendation in the Joint Proxy Statement (the “FNB Recommendation”). The Board of Directors of FNB shall use commercially reasonable efforts to obtain such approval. The FNB Proposal shall be submitted to the shareholders of FNB at

-50-

the FNB Shareholder Meeting for the purpose of approving the issuance of shares of FNB Common Stock in connection with the Merger. Notwithstanding the foregoing, if this Agreement is terminated pursuant to Section 8.1, FNB’s obligations pursuant to the first sentence of this Section 6.3(b) shall terminate.

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

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

(a) As soon as administratively practicable after the Effective Time, FNB shall take all reasonable action so that employees of Omega and its Subsidiaries shall be entitled to participate in each employee benefit plan, program or arrangement of FNB of general 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 Omega 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 Omega and its Subsidiaries until such employees are permitted to participate in the FNB Plans and provided further, however, that nothing contained herein shall require FNB or any of its Subsidiaries to make any grants to any former employee of Omega under any discretionary equity compensation plan of FNB. FNB shall cause each FNB Plans in which employees of Omega 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 Omega and its Subsidiaries to the same extent as such service was credited for such purpose by Omega, 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 Omega and its Subsidiaries that correspond to FNB Plans until employees of Omega and its Subsidiaries are included in such FNB Plans, nothing herein shall limit the ability of FNB to amend or terminate any of Omega’s Benefit Plans in accordance with and to the extent permitted by their terms at any time permitted by such terms.

-51-

(b) At and following the Effective Time, and except as otherwise provided in Section 6.7(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 Omega and its Subsidiaries and current and former directors of Omega 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 Omega that are set forth on Schedule 6.7(b) of the Omega 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 Omega are set forth on Schedule 6.7(b) of the Omega 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 Omega or its Subsidiaries who are terminated for other than cause, severance as set forth on Schedule 6.7(b) of the FNB Disclosure Schedule. Following the expiration of the foregoing severance policy, any years of service recognized for purposes of this Section 6.7(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 Omega 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 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, Omega shall, at the written request of FNB, freeze or terminate such of the Omega Benefit Plans as is requested by FNB, including Omega’s 401(k) Plan.

6.8 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 Omega or any of its Subsidiaries or who is or was serving at the request of Omega or any of its Subsidiaries as a director or officer 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 Omega or any of its Subsidiaries or was serving at the request of Omega or any of its Subsidiaries as a director or officer of another Person or (ii) this Agreement or any of the transactions contemplated by this Agreement, whether asserted or arising before or after the

-52-

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 Omega Articles, the Omega Bylaws and any agreement set forth in Section 6.8 of the Omega 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, 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 Omega Articles or the Omega 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 Omega Articles or the Omega 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 6.8 shall impair any rights or obligations of any current or former director or officer of Omega or its Subsidiaries, including pursuant to the respective organizational documents of Omega, or their respective Subsidiaries, under the PBCL or otherwise.

(c) Prior to the Effective Time, Omega shall obtain at the expense of FNB, 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 contemplated hereby, covering the Indemnified Persons who are currently covered by Omega’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 Omega or single premium tail coverage with policy limits equal to Omega’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 Omega 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 6.8(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 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

-53-

an insurer or insurers 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 contemplated hereby, on terms that are no less advantageous to Indemnified Persons than Omega’s D&O Insurance existing immediately prior to the date hereof. 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 6.8 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.

6.9 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 Omega, on the other) 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.

6.10 Advice of Changes. Each of FNB and Omega 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 6.10 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.

6.11 Dividends. After the date of this Agreement, Omega shall coordinate with FNB the declaration of any dividends in respect of Omega Common Stock and the record dates and payment dates relating thereto such that holders of Omega Common Stock shall not receive two dividends, or fail to receive one dividend, for any quarter with respect to their shares of Omega Common Stock and any shares of FNB Common Stock any such holder receives in exchange therefor in the Merger.

6.12 Exemption from Liability Under Section 16(b). Prior to the Effective Time, FNB and Omega shall take such steps as may be required to cause any acquisitions or dispositions of capital stock of FNB or Omega (including derivative securities thereof) resulting from the transactions contemplated by this Agreement by each individual who is subject to the

-54-

reporting requirements of Section 16(a) of the Exchange Act with respect to Omega to be exempt under Rule 16b-3 of the 1934 Act.

In all such cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision that, insofar as practicable, implements the original purposes and intents of this Agreement.

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. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by each of the parties and their respective successors and assigns. Except as otherwise specifically provided in Section 6.8 and 6.15, this Agreement (including the documents and instruments referred to in this Agreement) is not intended to and does not confer upon any person other than the parties hereto any rights or remedies under this Agreement.
