AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of June 13, 2013 (this “Agreement”), between F.N.B. CORPORATION, a Florida corporation (“FNB”), and BCSB BANCORP, INC., a Maryland corporation (“BCSB”).

W I T N E S S E T H:

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

WHEREAS, for federal income Tax (as defined in Section 3.10(b)) purposes, it is intended that the Merger shall qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations of the U.S. Department of the Treasury promulgated thereunder (as such regulations may be amended from time to time, including corresponding provisions of successor rules and regulations thereto, the “Treasury Regulations”); and

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

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

ARTICLE 1
THE MERGER

1.1                                           The Merger.

Subject to the terms and conditions of this Agreement, in accordance with the Maryland General Corporation Law (the “MGCL”) and the Florida Business Corporation Act (the “FBCA”), at the Effective Time (as defined in Section 1.2) BCSB 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 BCSB shall cease.

1.2                                           Effective Time.

The Merger shall become effective as set forth in the articles of merger (each, the “Articles of Merger”) that shall be filed with the Department of Assessments and Taxation of the

1

State of Maryland 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 MGCL and FBCA.  At and after the Effective Time, the Merger shall have the effects set forth in Section 3-114 of the MGCL and Section  ###-###-#### 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 BCSB Common Stock.

(a)                                 Subject to the provisions of this Agreement, each share of common stock, par value $0.01 per share, of BCSB (“BCSB 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 2.080 shares (the “Exchange Ratio”) of common stock, $0.01 par value, of FNB (“FNB Common Stock”) (the “Merger Consideration”).

(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 the shares of BCSB Common Stock held by BCSB or any of the BCSB Subsidiaries (as defined in Section 3.1(d)) 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 BCSB shall be closed as to holders of BCSB Common Stock immediately prior to the Effective Time other than to settle transfers of shares of BCSB Common Stock that occurred prior to the Effective Time, and no transfer of BCSB Common Stock by any such holder shall thereafter be made or recognized.  If, after the Effective Time, certificates representing shares of BCSB Common Stock (“Certificates”) are properly presented pursuant to Section 2.2(a) of this Agreement to the Exchange Agent (as defined in Section 2.1), such Certificates shall be cancelled and exchanged for FNB Common Stock held in book entry representing the number of whole shares into which the BCSB Common Stock represented by the Certificates was converted in the Merger, plus, if applicable pursuant to Section 1.4(e), 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).  All shares of FNB Common Stock, cash in lieu of fractional shares of FNB Common Stock and/or declared but unpaid dividends issued or paid upon the surrender for exchange of shares of BCSB Common Stock (or the provision of

2

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 BCSB Common Stock.

(d)                                 Each holder of BCSB 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”), as long as such shareholder enrolls with a minimum of 50 whole shares of FNB Common Stock.  Each BCSB shareholder electing to enroll in the DRSP Plan shall be issued FNB Common Stock held in book entry representing the number of whole shares received in the Merger.

(e)                                  Notwithstanding any other provision of this Agreement, each holder of BCSB 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 as reported by the NYSE for each of the twenty (20) consecutive trading days ending on and including the fifth such trading day prior to the specified date rounded to the nearest ten-thousandth.

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                                           BCSB Equity-Based Awards.

(a)                                 BCSB Stock Options.  Effective as of the Effective Time, each then outstanding option to purchase BCSB Common Stock (each, a “BCSB Stock Option”) pursuant to the equity-based compensation plans identified on Section 3.11(a) of the BCSB Disclosure Schedule (as defined in Article 3 hereof) (the “BCSB Stock Plans”) and the award agreements evidencing the grants thereunder, granted to any current or former employee or director of BCSB or any of the BCSB Subsidiaries (as defined in Section 3.1(d)) shall at the Effective Time cease to represent a right to acquire BCSB Common Stock and shall be converted automatically into an option to acquire shares of FNB Common Stock on the terms hereinafter set forth.  FNB shall assume each such BCSB Stock Option in accordance with the terms of the relevant BCSB Stock Plan and stock option or other agreement by which it is evidenced, except that from and after the Effective Time:  (i) FNB and the Compensation Committee of its Board of Directors, including, if applicable, the entire Board of Directors of FNB, shall be substituted for BCSB and the Compensation Committee of the Board of Directors of BCSB, including, if applicable, the entire Board of Directors of BCSB, administering such BCSB Stock Plan, (ii) each BCSB 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 BCSB Stock Option shall be equal to the number of shares of BCSB Common Stock subject to such BCSB Stock Option immediately prior to the

3

Effective Time multiplied by the Exchange Ratio (as adjusted, if applicable, pursuant to Section 2.3 herein), provided that, unless otherwise provided for in such BCSB Stock Option, 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 BCSB Stock Option prior to the Effective Time divided by the Exchange Ratio (as adjusted, if applicable, pursuant to Section 2.3 herein).  Notwithstanding clauses (iii) and (iv) of the preceding sentence, each BCSB Stock Option that is an “incentive stock option” shall be adjusted as required by Section 424 of the Code,  and the Treasury 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 BCSB agree to take all reasonable and necessary steps to effect the provisions of this Section 1.6(a). As of the Effective Time, FNB shall issue to each holder of each outstanding BCSB Stock Option that has been assumed by FNB a document evidencing the conversion and assumption of such BCSB Stock Option by FNB pursuant to this Section 1.6(a).

(b)                                 BCSB Share Awards.  At the Effective Time, each holder of any then outstanding restricted share awards relating to BCSB Common Stock, including those designated as performance share awards (each, a “BCSB Share Award”), shall be entitled to receive a number of shares of FNB Common Stock equal to the Exchange Ratio (as adjusted, if applicable, pursuant to Section 2.3 herein) multiplied by the total number of shares of BCSB Common Stock subject to such BCSB Share Award (provided that any fractional shares of FNB Common Stock resulting from such multiplication shall be rounded down to the nearest share), subject to any applicable tax withholding requirements.  Notwithstanding anything that may be to the contrary in this subparagraph (b), each BCSB Share Award shall remain subject to any applicable restrictions, vesting and other terms and conditions unless otherwise provided in the award agreement evidencing such BCSB Share Award or the relevant BCSB Stock Plan.

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

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

1.9                                           Dissenting Shares.  No right to fair value or appraisal or similar rights shall be available to holders of BCSB Common Stock with respect to the Merger or the other transactions contemplated hereby.

1.10                                    The Bank Merger.  As soon as practicable after the execution of this Agreement BCSB and FNB shall cause Baltimore County Savings Bank (“BCSB Bank”) and First National Bank of Pennsylvania (“FNB Bank”), respectively, to enter into a bank merger agreement, the form of which is attached to this Agreement as Exhibit “A” (the “Bank Merger Agreement”), and

4

which provides for the merger of BCSB 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.

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

ARTICLE 2
EXCHANGE OF SHARES

2.1                                           FNB to Make Merger Consideration Available.  As promptly as practicable following the Effective Time, FNB shall deposit, or shall cause to be deposited, with Registrar and Transfer Company (“Exchange Agent”), for the benefit of the holders of Certificates, for exchange in accordance with this Article 2, (i) book entry shares representing the aggregate number of shares of FNB Common Stock issuable pursuant to this Agreement in exchange for the shares of BCSB 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)(i), and (iii) cash in lieu of any fractional shares of FNB Common Stock to be issued pursuant to Section 1.4(e) and paid pursuant to Section 1.4 in exchange for outstanding shares of BCSB Common Stock (such cash and book entry shares for shares of FNB Common Stock, collectively being referred to as the “Exchange Fund”).

2.2                                           Exchange Shares.

(a)                                 As soon as practicable but in no event later than ten business days after the Effective Time, the Exchange Agent shall mail to each holder of record of BCSB Common Stock a letter of transmittal in customary form as prepared by FNB and reasonably acceptable to BCSB 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 BCSB 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 shares of BCSB 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

5

Agent, shall, upon acceptance thereof, be entitled to:  (i) book entry shares representing FNB Common Stock into which the shares of BCSB Common Stock shall have been converted pursuant to Section 1.4, (ii) any cash in lieu of any fractional share of FNB Common Stock to which such holder would otherwise be entitled and (iii) 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 shares of BCSB 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 BCSB 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, any cash in lieu of fractional shares and/or any declared but unpaid dividends to which any former holder of shares of BCSB 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 shares of FNB Common Stock, or any cash in lieu of fractional shares and/or declared but unpaid dividends, are to be issued in a name other than that in which a Certificate surrendered for exchange is issued, the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the person requesting such exchange shall affix any requisite stock transfer tax stamps to the Certificate surrendered or provide funds for their purchase or establish to the satisfaction of the Exchange Agent that such taxes are not payable.  If any Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit, in form and substance reasonably acceptable to FNB, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by FNB or the Exchange Agent, the posting by such Person of a bond in such amount as FNB and the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it, FNB or the Surviving Company with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

(b)                                 Following surrender of any such Certificate, there shall be paid to the record holder of the 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, if any, with a record date prior to the Effective Time that have been declared by BCSB in respect of shares of BCSB 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(e) and the amount of dividends or other distributions with a record date after the Effective Time of the Merger and which had become payable with respect to such whole shares of FNB Common Stock prior to the time of surrender, 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.

(c)                                  Any portion of the Exchange Fund, including any interest thereon, that remains undistributed to the shareholders of BCSB following the passage of twelve (12) months

6

after the Effective Time of the Merger shall be delivered to FNB, upon demand, and any shareholders of BCSB who have not theretofore complied with this Section 2.2 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).

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

(e)                                  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.

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, 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, then a proportionate adjustment or adjustments will be made to the Exchange Ratio and, as applicable, the Average Closing Price, 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, distributed or paid to holders of such class 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 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 shares of BCSB 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.  To the extent the amounts are so withheld by the Exchange Agent or FNB, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of BCSB Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or FNB, as the case may be.

Each Loan Held for Sale allocated to a particular Investor in accordance with standard secondary marketing practices of BCSB and the BCSB Subsidiaries is eligible for sale under an Investment Commitment.  Each Loan Held for Sale not allocated to a particular Investor in accordance with standard secondary marketing practices of BCSB and the BCSB Subsidiaries would be otherwise eligible for sale under an Investment Commitment upon allocation to an Investor.  To BCSB’s knowledge, no fact or circumstance exists that would entitle the applicable Insurer or Investor to (A) demand from BCSB or any BCSB Subsidiary or any Affiliate of BCSB or any BCSB Subsidiary, either the repurchase of any Serviced Loan or Previously Disposed of Loan or indemnification for losses, (B) refuse to purchase a Loan Held for Sale, (C) impose on BCSB, any BCSB Subsidiary or any Affiliate of BCSB or any BCSB Subsidiary, sanctions, penalties or special requirements in respect of any Mortgage Loan or (D) rescind any insurance policy or reduce insurance benefits in respect of any Mortgage Loan which would reasonably be expected to result in a breach of any obligation of BCSB, any BCSB Subsidiary or any Affiliate of BCSB or any BCSB Subsidiary under any agreement. Each Pipeline Loan complies in all material respects with all applicable laws, rules and regulations for the stage of processing that it has achieved based on the Investor or Insurer program, if applicable, under which BCSB, any BCSB Subsidiary or any Affiliate of BCSB or any BCSB Subsidiary originated the Pipeline Loan.

(ii)                                  Documentation/Enforceability.  Each Mortgage Loan is evidenced by a Mortgage Note and is duly secured by a valid first lien or subordinated lien on the related Mortgaged Property, in each case, on such forms and with such terms as comply in all material respects with all applicable Laws. Each Mortgage Note and the related Mortgage is genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms, subject to bankruptcy, insolvency and similar laws affecting generally the enforcement of creditors’ rights. No Mortgage Loan is subject to any rights of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note or the Mortgage, or the exercise of any right thereunder, render either the Mortgage Note or the Mortgage unenforceable by BCSB or a BCSB Subsidiary, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, and no such right of rescission, set-off, counterclaim, or defense has been asserted with respect thereto.

(iii)                               Compliance with Law.  BCSB and each BCSB Subsidiary, as the case may be, has complied, and each Mortgage Loan complied and complies, in all material respects, with respect to origination, sale and servicing of the Mortgage Loans,

with all applicable Laws required to have been complied with as of the Effective Date, including, without limitation, the fair housing, anti-redlining, equal credit opportunity, truth-in-lending, real estate settlement procedures, fair credit reporting, high cost and anti-predatory lending and every other prohibition against unlawful discrimination in residential mortgage lending or governing consumer credit, and also including, without limitation, the Fair Housing Act, Consumer Credit Reporting Act, Equal Credit Opportunity Act of 1975 and Regulation B, Fair Credit Reporting Act, Truth in Lending Act and Regulation Z, the Flood Disaster Protection Act of 1973, Fair Debt Collection Practices Act, Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act of 1974, and Regulation X, all as amended, and any applicable state consumer credit Law.  Each originator of a Mortgage Loan was qualified to do business, and had all requisite licenses, permits and approvals, in the states in which the properties associated with the Mortgage Loans are located, as well as the states in which the associated mortgage notes or mortgages were or are to be executed.

(iv)                              Good Title.  BCSB or BCSB Bank is the sole owner and holder of all right, title and interest in and to each Loan Held for Sale, Portfolio Loan and each Pipeline Loan. On the Effective Date, the Loans Held for Sale, the Portfolio Loans and the Pipeline Loans will be valid and enforceable in accordance with their terms and the Merger will effectively vest in FNB Bank good and marketable title to the Loans Held for Sale, the Portfolio Loans and the Pipeline Loans free and clear of any and all Liens. Neither BCSB, BCSB Bank nor any other BCSB Subsidiary or other Affiliate of BCSB or any BCSB Subsidiary has previously assigned, transferred or encumbered any of the Loans Held for Sale, the Portfolio Loans or the Pipeline Loans.

(v)                                 Origination and Servicing Practices.  The origination and servicing practices used by BCSB, each BCSB Subsidiary or any other Affiliate of BCSB or a BCSB  Subsidiary or any Originator with respect to each Mortgage Loan have been in all material respects legal, proper, prudent and customary in the mortgage lending business and in accordance with all applicable Laws. Except for customary industry standards for indemnification and repurchase remedies in connection with agreements for the sale or servicing of mortgage loans, none of BCSB, the BCSB Subsidiaries or other Affiliate of BCSB or a BCSB  Subsidiary is now or has been subject to or, to the knowledge of BCSB, threatened to be subject to any material fine, suspension, settlement or other agreement or administrative agreement or sanction by, or an obligation to indemnify, an Agency, an Insurer or an Investor, relating to the origination, sale or servicing of Mortgage Loans.

(vi)                              Loan-to-Value Ratio: Appraisals.  BCSB has relied on third-party appraisers to provide opinions and valuations upon which BCSB determines the loan-to-value ratio of Loans Held for Sale and committed Pipeline Loans. To BCSB’s knowledge, at the time of origination, the loan-to-value ratio of each Loan Held for Sale and each committed Pipeline Loan did not exceed the maximum amount permitted by the applicable Investor or Insurer for such Loan Held for Sale or Pipeline Loan. The appraisal prepared in connection with property associated with each Loan Held for Sale and each Pipeline Loan was prepared by a qualified appraiser with, to the knowledge of

29

BCSB, no direct or indirect interest in the property, and both the appraisal and appraiser satisfied all applicable Laws.

(vii)                           Fraud.  To BCSB’s knowledge, there has been no fraudulent action on the part of any Originator or Persons acting on behalf of the Originator in connection with the Origination of any Mortgage Loan or Pipeline Loan or the application of insurance proceeds with respect to a Mortgage Loan or the Mortgaged Property for which BCSB, any BCSB Subsidiary or any other Affiliate of BCSB or a BCSB Subsidiary is responsible to the applicable Investor or Insurer or otherwise bears the risk of loss.

(viii)                        High Cost Loans.  No Mortgage Loan is a “High Cost Loan” or “Covered Loan”, as applicable, under either the Home Ownership Equity Protection Act or a similar state or local anti-predatory lending law, statute, regulation or ordinance, including, without limitation, as such terms are defined in the then current Standard & Poor’s LEVELS and Glossary of Terms which is now Version 5.7 Revised, Appendix E.

Neither BCSB nor any BCSB Subsidiary has received any notice or information from any Governmental Entity that it intends to terminate or restrict the status of BCSB, any BCSB Subsidiary or any employee of BCSB or a BCSB Subsidiary as an approved participant in its Mortgage Business for which BCSB or any BCSB Subsidiary is registered, approved or authorized.

BCSB or BCSB Bank and, to BCSB’s knowledge, each other party thereto has duly performed all obligations required to be performed by it to date under each Servicing Agreement. No event or condition exists that constitutes, or after notice or lapse of time or both, will constitute, a breach, violation, or default on the part of BCSB or BCSB Bank, or, to BCSB’s knowledge, any other party thereto under any such Servicing Agreement. There are no material disputes pending or, to BCSB’s knowledge, threatened with respect to any Servicing Agreement. The Servicing of the Mortgage Loans complies in all material respects with all applicable Laws.

All Custodial Accounts required to be maintained by BCSB, BCSB Bank or any other BCSB Subsidiary have been established and continuously maintained in accordance with all applicable Laws.

(d)                                 The books and records of FNB and its Subsidiaries have been, and are being, maintained in all material respects in accordance with applicable legal and accounting requirements and reflect only actual transactions.  The records, systems, controls, data and information of FNB and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership and direct control of FNB or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a Material Adverse Effect on the system of internal accounting controls described in the following sentence. FNB and its Subsidiaries have implemented and maintain a system of internal accounting controls effective to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP.  FNB (i) has implemented and maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) effective to ensure that material information relating to FNB, including its consolidated Subsidiaries, is made known to the Chief Executive Officer and the Chief Financial Officer of FNB by others within those entities to allow timely decisions regarding required disclosure and to make the certifications required by the Exchange Act with respect to the FNB Reports and (ii) has disclosed, based on its most recent evaluation prior to the date of this Agreement, to FNB’s outside auditors and the audit committee of the board of directors of FNB (A) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that would be reasonably likely to adversely affect FNB’s ability to accurately record, process, summarize and report financial information and (B) any fraud, whether or not material, that involves management or other employees who have a significant role in FNB’s internal controls over financial reporting.

(e)                                  Since January 1, 2010, (A) neither FNB nor any of its Subsidiaries nor, to the knowledge of FNB, any director, officer, employee, auditor, accountant or representative of FNB or any of its Subsidiaries has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of FNB or any of its

40

Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that FNB or any of its Subsidiaries has engaged in questionable accounting or auditing practices, and (B) no attorney representing FNB or any of its Subsidiaries, whether or not employed by FNB or any of its Subsidiaries, has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by FNB or any of its officers, directors, employees or agents to the board of directors of FNB or any committee thereof or to any of FNB’s directors or officers.

4.7                                           Broker’s Fees.  Except as set forth in Section 4.7 of the FNB Disclosure Schedule, neither FNB nor any FNB Subsidiary nor any of their respective officers or directors has employed any broker or finder or incurred any liability for any broker’s fees, commissions or finder’s fees in connection with the Merger or related transactions this Agreement contemplates.

4.8                                           Absence of Certain Changes or Events.  Since December 31, 2012, except as publicly disclosed in the Forms 10-K, 10-Q and 8-K comprising the FNB Reports (as defined in Section 4.6(a)) 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 relating to FNB, any of its Subsidiaries or any of their respective properties or permits, licenses or authorizations that has had, or is reasonably likely to have, a Material Adverse Effect on FNB.

(b)                                 There is no judgment or order of any Governmental Entity or regulatory restriction, other than those of general application that apply to similarly situated financial or bank holding companies or their Subsidiaries, that has been imposed upon FNB, any of its Subsidiaries or the assets of FNB or any of its Subsidiaries that has had or is reasonably likely to have, a Material Adverse Effect on FNB.

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 not yet delinquent or are being contested in good faith, which have not been finally determined, and (ii) have been adequately reserved against in accordance with GAAP.  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 progress or pending, including any notice received of any intent to conduct an audit or examination, or claims asserted, for Taxes upon FNB or any of its

41

Subsidiaries.  No claim has been made by a Governmental Entity in a jurisdiction where 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.  Except as set forth on Section 4.10 of the FNB Disclosure Schedule, 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 corporation” 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 Governmental Entity, relating to Taxes, including any IRS private letter rulings or comparable rulings of any Governmental Entity 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).  BCSB 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 on and after January 1, 2009, and (ii) any audit report issued within the last three years 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

42

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 of this Agreement, the following terms shall have the following meaning:

“FNB Benefit Plan” means any 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, equity compensation, severance, employment, change of control or fringe benefit plan, program or policy.

“FNB Employment Agreement” means a 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.

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

(b)                                 With respect to each FNB Benefit Plan, FNB has delivered or made available to BCSB, as applicable, a true, correct and complete copy of:  (i) each writing constituting a part of such FNB Benefit Plan, including without limitation all plan documents, trust agreements, and insurance contracts and other funding vehicles, (ii) the two most recent Annual Reports (Form 5500 Series) and accompanying schedules, if any, (iii) the current summary plan description and any summaries of material modifications, (iv) the most recent annual financial report for each applicable FNB Benefit Plan, if any, (v) the most recent actuarial report, if any, and (vi) the most recent determination or opinion letter from the IRS, if any, and (vii) the most recent minimum coverage and discrimination testing results, if any.  FNB has delivered or made available to BCSB a true, correct and complete copy of each FNB Employment Agreement.

(c)                                  All contributions required to be made to any FNB Benefit Plan by applicable Law or by any plan document or other contractual undertaking, and all premiums due or payable with respect to insurance policies funding any FNB Benefit Plan, for the period six years prior to and through the date of this Agreement, have been timely made or paid in full or, to the extent not required to be made or paid on or before the date of this Agreement, 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

43

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 Benefit Plan, FNB and its Subsidiaries have complied, and are in compliance, in all material respects, with all provisions of ERISA, the Code and all laws and regulations applicable to such FNB Benefit Plans, including, without limitation, Code Section 409A.  Each FNB Benefit Plan has been administered in all material respects in accordance with its terms.  There are 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 Benefit 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 Benefit 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 FNB Qualified Plan and the related trust which has not been revoked, or FNB is entitled to rely on a favorable opinion issued by the IRS.  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.  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 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)                                  No FNB Benefit Plan that is subject to Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code has failed to satisfy the minimum funding standards contained in Section 302 of ERISA and Section 412 of the Code.  With respect to such FNB Benefit Plans, except as would not have, individually or in the aggregate, a Material Adverse Effect:  (i) the fair market value of the assets of such FNB Benefit Plan equals or exceeds the actuarial present value of all accrued benefits under such FNB Benefit Plan, whether or not vested, on a termination basis, (ii) 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, (iii) all premiums to the PBGC have been timely paid in full, (iv) 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 (v) the PBGC has not instituted proceedings to terminate any such FNB Benefit Plan and, to FNB’s knowledge, no condition exists that makes it reasonably likely 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 Benefit 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

44

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 or the FNB Employment Agreements.  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 Sections 4069, 4204 or 4212 of ERISA.

(g)                                  Other than as set forth in Section 4.11(g) of the FNB Disclosure Schedule, 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 this Agreement contemplates will, either alone or in conjunction with any other event, whether contingent or otherwise, (i) result in any payment or benefit becoming due or payable, or required to be provided, to any director, employee or independent contractor of 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, including deferred compensation, or (iv) result in any amount failing to be deductible by reason of Section 280G of the Code or would be subject to an excise tax under Section 4999 of the Code or additional tax under Section 409A of the Code.

(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 presently pending or, to FNB’s knowledge, threatened to be brought or filed, with the National Labor Relations Board.  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                                    Compliance with Applicable Law.  FNB and each of its Subsidiaries are not in violation or noncompliance in any material respect under any Laws applicable 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, the Dodd-Frank Wall Street Reform and Consumer Protection Act, Regulation O and applicable limits on loans to one borrower, except where such violation or noncompliance is not reasonably likely to, either individually or in the aggregate, have a Material Adverse Effect on FNB.  FNB and each of the FNB Subsidiaries has been and is in compliance in all material respects with (i) the applicable provisions of the Sarbanes-Oxley Act and (ii) the applicable listing and corporate governance rules and regulations of the NYSE.

45

4.13                                    Contracts.  Except for matters that have not had and would not reasonably be likely to have, individually or in the aggregate, a Material Adverse Effect on FNB, (a) 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, (b) 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 (c) neither FNB 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 FNB or any of its Subsidiaries.

4.14                                    Agreements with Regulatory Agencies.  Neither FNB nor any of its Subsidiaries is subject to any cease-and-desist or other order or 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 directive by, or has been since January 1, 2010, a recipient of any notice of a formal or informal enforcement action from, or has been ordered to pay any civil money penalty by, or has been since October 1, 2010, a recipient of any supervisory letter from, or since January 1, 2010, 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, a “FNB Regulatory Agreement”), nor has FNB or any of its Subsidiaries been advised since January 1, 2010 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 are no investigations relating to any material regulatory matters pending before any Governmental Entity with respect to FNB or any of its Subsidiaries.  Each bank Subsidiary of FNB has at least a “satisfactory” rating under the U.S. Community Reinvestment Act.

4.15                                    Undisclosed Liabilities.  Neither FNB nor any of its Subsidiaries has, and since December 31, 2012, neither FNB nor any of its Subsidiaries has incurred, any liabilities or obligations, whether accrued, absolute, contingent or otherwise, known or unknown, whether due or to become due, except (i) those liabilities fully accrued or reserved against in the unaudited consolidated balance sheet of FNB and its Subsidiaries as of March 31, 2013 included in the FNB Reports, (ii) for liabilities and obligations incurred in the ordinary course of business consistent with past practice since March 31, 2013, (iii) for liabilities and obligations that are not material to FNB and its Subsidiaries, taken as a whole, and (iv) for any liabilities incurred with respect to the transactions contemplated by this Agreement.

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

4.18                        Loans; Nonperforming and Classified Assets.

(a)                                 Each Loan on the books and records of FNB and its Subsidiaries (i) was made and has been serviced in all material respects in accordance with their customary lending standards in the ordinary course of business, (ii) is evidenced in all material respects by appropriate and sufficient documentation, (iii) to the extent secured, has been secured by valid liens and security interests which have been perfected in accordance with all applicable Laws and, (iv) to the knowledge of FNB, constitutes the legal, valid and binding obligation of the obligor named in the contract evidencing such loan, subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar Laws of general applicability relating to or affecting creditor’s rights or by general equity principles.

(b)                                 Each of BCSB and FNB agrees 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 therein or necessary to make the statements therein not misleading.  Each of BCSB and FNB agrees that none of the 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 therein or necessary to make the statements therein not misleading.  Each of BCSB 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 therein not false or misleading, to promptly inform the other party 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 BCSB.

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.  BCSB 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 BCSB or FNB, as the case may be, and any of their respective Subsidiaries, which appear in any filing made with, or written materials submitted to, any third party, Regulatory Agency or any Governmental Entity in connection with the transactions contemplated by this Agreement.  In exercising the foregoing right, each of the parties shall act reasonably and as promptly as practicable.  The parties shall consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties, Regulatory Agencies and Governmental Entities necessary or advisable to consummate the transactions this Agreement contemplates and each party will keep the other apprised of the status of matters relating to completion of the transactions this Agreement contemplates.  Notwithstanding the foregoing, nothing in this Agreement shall be deemed to require FNB to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of third parties, Regulatory Agencies or Governmental Entities, that would reasonably be expected to have a Material Adverse Effect on FNB, including the Surviving Company, after giving effect to the Merger, after the Effective Time (a “Materially Burdensome Regulatory Condition”).  In addition, BCSB 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 BCSB and FNB following consummation of the Merger.

(e)                                  Each of FNB and BCSB 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, BCSB 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 BCSB shall promptly provide each other with any written communications received from any Regulatory Agency or Governmental Entity with respect to the transactions contemplated by this Agreement and will promptly advise the other

56

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

(g)                                  BCSB 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 Federal Reserve Board, the FDIC, the OCC, the NYSE or NASDAQ.  In addition, the Chief Executive Officers of BCSB and FNB shall be permitted to respond to appropriate questions about the Merger from the press.  BCSB 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.

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

57

6.3                                           BCSB Shareholder Approval.  BCSB shall call a meeting of its shareholders for the purpose of obtaining the shareholder approval specified in Section 3.3(a) which is required in connection with this Agreement and the Merger (the “BCSB Shareholders Meeting”), and shall use its reasonable best efforts to convene such meeting as soon as reasonably practicable following the Registration Statement being declared effective, giving a reasonable amount of time for printing and mailing.  Subject to Section 6.11, the Board of Directors of BCSB shall recommend approval and adoption of this Agreement, the Merger and the other transactions this Agreement contemplates, by BCSB’s shareholders and shall include such recommendation in the Proxy Statement (the “BCSB Recommendation”).  Without limiting the generality of the foregoing, BCSB’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 BCSB of any Acquisition Proposal, as defined in Section 6.11(e)(i).

6.4                                           Commercially Reasonable Efforts; Cooperation.  Each of BCSB 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.

6.6                                           Benefit Plans.

(a)                                 As soon as administratively practicable after the Effective Time, FNB shall take all reasonable action so that employees of BCSB and the BCSB Subsidiaries shall be entitled to participate in each FNB Benefit Plan of general applicability with the exception of FNB’s defined benefit pension plan and any other plan frozen to new participants (collectively, the “FNB Eligible Plans”) to the same extent as similarly-situated employees of FNB and its Subsidiaries, it being understood that inclusion of the employees of BCSB and the BCSB Subsidiaries in the FNB Eligible Plans may occur at different times with respect to different plans, provided that coverage shall be continued under corresponding BCSB Benefit Plans until such employees are permitted to participate in the FNB Eligible 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 BCSB under any discretionary equity compensation plan of FNB or to provide the same level of (or any) employer contributions or other benefit subsidies as BCSB or the BCSB Subsidiaries.  FNB shall cause each FNB Eligible Plan in which employees of BCSB and the BCSB Subsidiaries are eligible to participate, to recognize, for purposes of determining eligibility to participate in, and vesting of, benefits under the FNB Eligible Plans, the service of such employees with BCSB and the BCSB Subsidiaries to the same extent as such service was credited for such purpose by BCSB or the BCSB Subsidiaries, and, solely for purposes of FNB’s vacation programs, for purposes of determining the benefit amount, 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 BCSB Benefit Plans that correspond to FNB Eligible Plans until employees of BCSB and the BCSB Subsidiaries are included in such FNB Eligible Plans, nothing in this Agreement shall limit the

58

ability of FNB to amend or terminate any of the BCSB Benefit Plans in accordance with and to the extent permitted by their terms at any time permitted by such terms.

At and following the Effective Time, and except as otherwise provided in Section 6.6(e) or as agreed to be amended or revised pursuant to the Executive Compensation proposals executed as of even date herewith, 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 BCSB and the BCSB Subsidiaries and current and former directors of BCSB and the BCSB Subsidiaries existing as of the Effective Date under any BCSB Benefit Plan.  Any years of service recognized for purposes of this Section 6.6(a) will be taken into account under the terms of any generally applicable severance policy of FNB or its Subsidiaries.

Employees of BCSB and the BCSB Subsidiaries (other than those who are parties to an employment, change of control or other type of agreement with BCSB and the BCSB subsidiaries which provides for severance) as of the date of the Agreement who remain employed by BCSB and the BCSB subsidiaries as of the Effective Time and whose employment is terminated by BCSB and the BCSB subsidiaries or FNB (absent termination for cause as determined by the employer) within one year after the Effective Time shall receive severance pay under any severance pay plans that may be in effect at such time at FNB, provided that any such severance pay shall be no less than such severance pay as is provided for under FNB’s severance pay plan as is in effect on the date hereof.

(b)                                 At such time as employees of BCSB and the BCSB Subsidiaries become eligible to participate in a medical, dental or health plan of FNB or its Subsidiaries, FNB shall, to the extent reasonably practicable and available from its insurers, cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of 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 BCSB Benefit Plan prior to the Effective Time.

(c)                                  BCSB shall adopt such Board resolutions and take such other action as FNB may reasonably request to cause the Baltimore County Savings Bank Employee Savings Plan 401(k) Plan (the “Plan”) to be terminated immediately prior to the Effective Time (the “Plan Termination Date”) and the accounts of all participants and beneficiaries in the Plan as of the Plan Termination Date to become fully vested as of the Plan Termination Date.  As soon as practicable after the Effective Time, but in no event later than one year after the Plan Termination Date, FNB shall file or cause to be filed all necessary documents with the IRS for a determination letter that the termination of the Plan as of the Plan Termination Date will not adversely affect the Plan’s qualified status.  FNB shall use its reasonable best efforts to obtain such favorable determination letter; including, but not limited to, adopting such amendments to the Plan as may be requested by the IRS as a condition to its issuance of a favorable determination letter.  As soon as practicable following the receipt of a favorable determination letter from the IRS regarding the qualified status of the Plan upon its termination, the account balances in the Plan shall be distributed to participants and beneficiaries or transferred to an

59

eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct.  The Surviving Company shall take all other actions necessary to complete the termination of the Plan, including filing a Final Form 5500, that arise after the Effective Time.  FNB agrees, to the extent permitted by applicable Law, to permit Plan participants who become employees of FNB or its Subsidiaries to roll over their account balances in the Plan and loans from the Plan to the F.N.B. Corporation Progress Savings 401(k) Plan. Notwithstanding anything in Section 6.6(a) to the contrary, employees of BCSB or any BCSB Subsidiary who continue in employment with the Surviving Company following the Effective Time shall be eligible as of the Effective Time to participate in the F.N.B. Corporation Progress Savings 401(k) Plan.

(d)                                 BCSB and BCSB Bank shall, effective no later than immediately prior to, and contingent upon the Closing, adopt such resolutions and or amendments to the ESOP, the ESOP trust or the ESOP Loan documents (if any) (and take any other required action) to (i) direct the ESOP trustee(s) to sell or otherwise dispose of shares of BCSB Common Stock held in the ESOP’s Loan Suspense Account (as defined in the ESOP) and use the proceeds of such sale to repay any outstanding ESOP Loans, (ii) provide for treatment of the shares of BCSB Common Stock held in the ESOP trust in accordance with Article 1 of this Agreement, (iii) terminate the ESOP in accordance with its terms and the provisions of this Section 6.6(d), effective as of the Effective Time, and (iv) provide that no new participants shall be admitted to the ESOP after the Closing.  The accounts of all participants and beneficiaries in the ESOP as of the Effective Time shall become fully vested as of the Effective Time.  Any unallocated shares of BCSB Common Stock held in the ESOP after repayment of the ESOP Loans shall be converted into Merger Consideration and shall be allocated as earnings to the accounts of ESOP participants who have account balances in the ESOP as of the Effective Time based on their account balances under the ESOP as of the Effective Time.  As soon as practicable after the Effective Time, FNB shall file or cause to be filed all necessary documents with the IRS for a determination letter for termination of the ESOP.  As soon as practicable following the receipt of a favorable determination letter from the IRS regarding the qualified status of the ESOP upon its termination, the account balances in the ESOP shall either be distributed to participants and beneficiaries or transferred to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct, except that, to the extent provided by the ESOP, ESOP participants whose employment is terminated by FNB may elect to receive their ESOP account balance prior to the receipt of the IRS determination letter but following their termination of employment.  FNB agrees to permit ESOP participants who become employees of FNB or its Subsidiaries to roll over their account balances in the ESOP to the F.N.B. Corporation Progress Savings 401(k) Plan.

(e)                                  Immediately prior to the Effective Time, BCSB shall, at the written request of FNB, freeze or terminate each other BCSB Benefit Plan as is requested by FNB.

(f)                                   BCSB shall take such action, and provide any required notices, as may be necessary or appropriate to cause any Person presently serving as a trustee or administrator to any BCSB Benefit Plan to be removed effective as of the Effective Time and to appoint First National Trust Company, or such other FNB Subsidiary or committee as FNB shall specify, to serve as successor trustee or administrator to such removed individual trustees or administrators effective as of the Effective Time.

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 BCSB or any of the BCSB Subsidiaries or who is or was serving at the request of BCSB or any of the BCSB Subsidiaries as a director, officer, employee, trustee, agent, member or otherwise of another Person or in any capacity with respect to any BCSB Benefit Plan (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 BCSB or any of the BCSB Subsidiaries or was serving at the request of the BCSB or any of the BCSB Subsidiaries as a director, officer, employee, trustee, agent, member or otherwise of another Person or in any capacity with respect to any BCSB Benefit Plan 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 such Claim and respond thereto.  From and after the Effective Time, but subject to subsection (b) below, FNB shall, and shall cause the Surviving Company to, indemnify and hold harmless, as and to the fullest extent currently provided under applicable Law, the BCSB Charter and the BCSB Bylaws, 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 upon receipt of any undertaking required by applicable Law, and judgments, fines and amounts paid in settlement in connection with any such threatened or actual Claim.

(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 under Section 6.7(a), shall survive the Merger and shall continue in full force and effect, without any amendment thereto; provided, however, that for Claims asserted or made after the Effective Time, any determination required to be made with respect to whether an Indemnified Person’s conduct complies with the standards set forth under the MGCL, the BCSB Charter or the BCSB 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 BCSB or its Subsidiaries, including pursuant to the respective organizational documents of BCSB, or their respective Subsidiaries, under the MGCL or otherwise.

(c)                                  Prior to the Effective Time, FNB shall obtain at the expense of BCSB, 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 BCSB’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 BCSB or

61

single premium tail coverage with policy limits equal to BCSB’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 BCSB 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 BCSB’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 FNB shall maintain such policies in full force and effect and continue the obligations thereunder.

(d)                                 The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.  If FNB or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of FNB shall assume the obligations set forth in this Section 6.7.

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

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

6.10                                    Dividends.  After the date of this Agreement, BCSB shall not declare or pay any dividend in respect of shares of BCSB Common Stock.

62

63

to the extent required by applicable Law.  In addition to the foregoing, BCSB shall not submit to the vote of its shareholders any Acquisition Proposal other than the Merger prior to the termination of this Agreement.

F.N.B. Corporation

One F.N.B. Boulevard

Ladies and Gentlemen:

Concurrently with the execution of this letter agreement (“Voting Agreement”), F.N.B.

All defined terms used but not defined herein shall have the meanings ascribed thereto in the Merger Agreement.

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

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

(a)                                 As of the date of this Voting Agreement, I have, and at all times during the term of this Voting Agreement will have, beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of, and good and valid title to, the number of shares of common stock, par value $0.01 per share, of BCSB (the “BCSB Common Stock”), that is set forth on Appendix A hereto, and I hold stock options to acquire the number of shares of BCSB Common Stock set forth on Appendix A hereto.  All of the securities listed on Appendix A are owned free and clear of any proxy or voting restriction, claims, liens, encumbrances and security interests and any other limitation or restriction whatsoever (including any restriction on the right to dispose of such securities).  None of the securities listed on Appendix A are subject to any voting trust or other agreement or arrangement with respect to the voting rights of such securities.

(b)                                 As of the date of this Voting Agreement, except for the securities set forth on Appendix A, I do not beneficially own any (i) shares of capital stock or voting securities of BCSB, (ii) securities of BCSB convertible into or exchangeable for shares of capital stock or voting securities of BCSB or (iii) options or other rights to acquire from BCSB any capital stock, voting securities or securities convertible into or exchangeable for capital stock or voting securities of BCSB. The BCSB Common Stock listed on Appendix A, together with all BCSB Common Stock that I subsequently acquire during the term of this Voting Agreement, including through the exercise of any stock options, warrants or similar instruments, are referred to herein as the “Shares”.

(c)                                  At the BCSB Shareholders Meeting and at any other meeting of BCSB shareholders, however called, and on every action or approval by written consent of shareholders of BCSB, I will vote or cause to be voted all Shares over which I have sole voting power, and I

B-1

will use reasonable efforts to cause any Shares over which I share voting power to be voted in favor of (i) approval and adoption of the Merger Agreement and the transactions contemplated thereby,  and (ii) any proposal to adjourn or postpone such meeting to a later date if there are not sufficient votes to approve the Merger Agreement.  Determinations as to “sole” or “shared” voting power shall be made in accordance with Rule 13d-3 of the Exchange Act.

(d)                                 During the term of this Voting Agreement, I will not, directly or indirectly, offer, sell, transfer, pledge, encumber or otherwise dispose of (collectively, “Transfer”) any Shares over which I have sole dispositive power (or any interest therein), and I will use reasonable efforts to not permit the Transfer of any Shares over which I have shared dispositive power (or any interest therein), except to the extent permitted by paragraph (g) hereof.

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

(f)                                   I represent that I have the legal capacity to enter into this Voting Agreement, that I have duly and validly executed and delivered this Voting Agreement and that this Voting Agreement is a valid and binding obligation enforceable against me in accordance with its terms, subject to bankruptcy, insolvency and other laws affecting creditors’ rights and general equitable principles; and further, that no consent of my spouse is necessary under any “community property” or other laws in order for me to enter into and perform my obligations under this Voting Agreement.

(g)                                  Notwithstanding anything herein to the contrary, I may Transfer any or all of the Shares over which I have beneficial ownership: (a) to my spouse, ancestors or descendants; provided, however, that in any such case, prior to and as a condition to the effectiveness of such Transfer, each person to which any of such Shares or any interest in any of such Shares is or may be Transferred shall have executed and delivered to FNB an agreement to be bound by the terms of this Voting Agreement; (b) transfers for estate and trust planning and related tax planning purposes, including transfers to relatives, trusts, foundations and charitable organizations, subject to the transferee first agreeing in writing to be bound by the terms of this Voting Agreement; (c) transfers by will or operation of law; and (d) such transfers as FNB may otherwise permit in its sole discretion.

I am signing this Voting Agreement solely in my capacity as a shareholder of BCSB and as an optionholder and/or warrantholder, if I am such, and not in any other capacity, such as a director or officer of BCSB or as a fiduciary of any trusts in which I am not a beneficiary. Notwithstanding anything herein to the contrary: (a) I make no agreement or understanding herein in any capacity other than in my capacity as a beneficial owner of BCSB Common Stock and (b) nothing herein shall be construed to limit, prevent or otherwise affect any action or inaction by me or any of my representatives, as applicable, in serving on BCSB’s Board of Directors or as an officer of BCSB, in acting in my capacity as a director, officer or fiduciary of BCSB or in exercising my fiduciary obligations in the context of a Superior Proposal.

This Voting Agreement shall terminate and be of no further force and effect concurrently with, and automatically upon, the earlier to occur of (a) the favorable vote of the BCSB

shareholders with respect to the approval of the Merger Agreement, (b) the Effective Time, (c) FNB and I enter into a written agreement to terminate this Voting Agreement, or (d) any termination of the Merger Agreement in accordance with its terms, except that any such termination shall be without prejudice to FNB’s rights if termination should arise out of my willful breach of any covenant or representation contained herein.

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

This Voting Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties. This Voting Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter of this Voting Agreement.  My obligations under this Voting Agreement shall be binding upon my heirs, executors, administrators, personal representatives, successors and permitted assigns.

I agree and acknowledge that FNB may be irreparably harmed by, and that there may be no adequate remedy at law for, any violation of this Voting Agreement by me.  Without limiting other remedies, FNB shall have the right to seek to enforce this Voting Agreement by specific performance or injunctive relief.  This Voting Agreement and all claims arising hereunder or relating hereto, shall be governed and construed and enforced in accordance with the laws of the Commonwealth of Pennsylvania, without giving effect to the principles of conflicts of law thereof.

If any term, provision, covenant or restriction of this Voting Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Voting Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party.  Upon such a determination, the parties shall negotiate in good faith to modify this Voting Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

This Voting Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same instrument.
