W I T N E S S E T H:

WHEREAS, the Boards of Directors of UBNC 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 UBNC 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 (hereinafter sometimes referred to in such capacity as the “Surviving Company”); and

WHEREAS, as a material inducement to FNB to enter into this Agreement, each of the Persons set forth on Schedule I attached hereto have entered into a voting agreement with FNB dated as of the date hereof, substantially in the form attached hereto as Exhibit A, pursuant to which each such Person has agreed, among other things, to vote all shares of UBNC Common Stock (as defined herein) owned or controlled by such Person in favor of the approval of this Agreement and the transactions contemplated hereby, upon the terms and subject to the conditions set forth in this Agreement; and

WHEREAS, for U.S. federal income tax purposes, it is intended that (i) 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”), (ii) FNB and UBNC each be a party to the reorganization within the meaning of Section 368(b) of the Code (clauses (i) and (ii), the “Intended Tax Treatment”), and (iii) this Agreement be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code and within the meaning of Treas.

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 Section 55-11-01 of the North Carolina Business Corporation Act (as amended or supplemented hereafter, the “NCBCA”), and Section 331 of the Pennsylvania Entity Transactions

Law (as amended or supplemented hereafter, “ETL”), at the Effective Time, UBNC 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 Commonwealth of Pennsylvania. As of the Effective Time, the separate corporate existence of UBNC shall cease.

1.2    Effective Time. The Merger shall become effective as set forth in the articles of merger that shall be filed with the Secretary of State of the State of North Carolina (the “North Carolina Articles of Merger”) in accordance with the NCBCA and the articles of merger that shall be filed with the Secretary of State of the Commonwealth of Pennsylvania (the “Pennsylvania Articles of Merger”), respectively, on or before the Closing Date. The term “Effective Time” shall mean the date and time when the Merger becomes effective as set forth in the North Carolina Articles of Merger and the Pennsylvania Articles of Merger.

1.3    Effects of the Merger.

(a)    Effects Under NCBCA and ETL. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of (i) Section 55-11-06 of the NCBCA, and (ii) the ETL.

(b)    Directors and Executive Officers of the Surviving Company. The directors of the Surviving Company at and immediately after the Effective Time shall be the directors of FNB immediately prior to the Merger. The executive officers of the Surviving Company at and immediately after the Effective Time shall be the executive officers of FNB immediately prior to the Merger.

1.4    Conversion of UBNC Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of UBNC, FNB or the holder of any of the following securities:

(a)    Subject to the provisions of this Agreement, each share of Common Stock, no par value, of UBNC (the “UBNC Common Stock”) issued and outstanding immediately prior to the Effective Time, other than Treasury Shares and Dissenting Shares (as defined below), 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 consideration in the Merger, 1.61 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 UBNC Common Stock held by UBNC, any UBNC Subsidiaries, FNB or any FNB Subsidiaries, in each case other than shares of UBNC Common Stock held in UBNC Benefit Plans or related trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary, including custodial or agency, capacity or as a result of debts previously contracted in good faith.

(c)    Notwithstanding anything in this Agreement to the contrary, all shares of UBNC Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by a UBNC shareholder who did not vote in favor of the Merger (or consent

- 2 -

thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who complies in all respects with, the provisions of Article 13 of the NCBCA, shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead the holder of such Dissenting Shares (hereinafter called a “Dissenting Shareholder”) shall be entitled to payment of the fair value of such shares in accordance with the applicable provisions of the NCBCA (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the NCBCA and this Section 1.4(c)), unless and until such Dissenting Shareholder shall have failed to perfect such holder’s right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the fair value of such shares of UBNC Common Stock under the applicable provisions of the NCBCA. If any Dissenting Shareholder shall fail to perfect or effectively withdraw or lose such UBNC shareholder’s dissenter’s rights under the applicable provisions of the NCBCA, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Merger Consideration, without any interest thereon, in accordance with the applicable provisions of this Agreement. UBNC shall give FNB (i) prompt notice, and a copy, of any written notices to exercise dissenters’ rights in respect of any shares of UBNC Common Stock, attempted withdrawals of such notices and any other instruments and documents served pursuant to the NCBCA and received by UBNC relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the NCBCA. UBNC shall not, except with the prior written consent of FNB or as otherwise required by applicable Law, make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Exchange Fund (as defined herein) made available to the Exchange Agent pursuant to Article 2 to pay for shares of UBNC Common Stock for which dissenters’ rights have been perfected shall be returned to FNB upon demand. If the amount paid to a Dissenting Shareholder exceeds the value of such Dissenting Shareholder’s pro rata portion of the Exchange Fund, such excess amount shall not reduce the Merger Consideration paid to other UBNC shareholders.

(d)    At the Effective Time, the stock transfer books of UBNC shall be closed as to holders of UBNC Common Stock immediately prior to the Effective Time and no transfer of shares of UBNC Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, certificates representing shares of UBNC Common Stock (“Certificates,” it being understood that any reference herein to “Certificates” shall be deemed to include reference to shares of UBNC Common Stock held in book entry form) are properly presented pursuant to Section 2.2(a) of this Agreement to the Exchange Agent, such Certificates shall be cancelled and exchanged for FNB Common Stock held in book entry form representing the number of whole shares into which the shares of UBNC Common Stock represented by the Certificates was converted in the Merger, plus, if applicable pursuant to Section 1.4(f), any payment for any fractional share of FNB Common Stock (without any interest thereon) and any dividends or distributions to which the holder of such Certificates is entitled pursuant to Section 2.2(b).

(e)    Each holder of UBNC 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”),

- 3 -

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

(f)    Notwithstanding any other provision of this Agreement, each holder of UBNC Common Stock who would otherwise be entitled to receive a fractional share of FNB Common Stock, after taking into account all shares of UBNC Common Stock owned by such holder as of immediately prior to the Effective Time, 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 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 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 (5^th) such trading day prior to the Closing 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    UBNC Equity Awards.

(a)    UBNC Stock Options. (i) Each outstanding option that was granted to purchase shares of UBNC Common Stock (each, a “UBNC Stock Option”) under an equity-based compensation plan identified in Section 1.6(a) of the UBNC Disclosure Schedule (collectively, the “UBNC Equity Plans”) that remains unexercised immediately prior to the Effective Time shall, at the Effective Time, cease to represent a right to acquire shares of UBNC Common Stock and (except for Exercised UBNC Stock Options, which shall be treated as set forth in clause (ii) below) shall be assumed by FNB and converted automatically into an option to acquire that number of whole shares of FNB Common Stock (rounded down to the nearest whole share) equal to the product obtained by multiplying (a) the number of shares of UBNC Common Stock subject to such UBNC Stock Option immediately prior to the Effective Time and (b) the Exchange Ratio, with an exercise price per share (rounded up to the nearest whole cent) obtained by dividing (i) the per share exercise price under each such UBNC Stock Option immediately prior to the Effective Time by (ii) the Exchange Ratio. Each such UBNC Stock Option as so assumed and converted shall continue to have, and shall be subject to, the same terms and conditions as applicable immediately prior to the Effective Time, including without limitation any vesting upon the occurrence of the Effective Time, except as provided in this Section 1.6(a) and that from and after the Effective Time, FNB and the Compensation Committee of the FNB Board of Directors, including, if applicable, the entire Board of Directors of FNB, shall be substituted for UBNC and the Compensation Committee of the Board of Directors of UBNC, including, if applicable, the entire Board of Directors of UBNC, administering such UBNC Equity Plans. Notwithstanding the foregoing, each UBNC 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

- 4 -

modification, extension or renewal of the option within the meaning of Section 424(h) of the Code and each UBNC Stock Option that is an option not intended to qualify as an “incentive stock option” shall be adjusted as required by Section 409A of the Code and the Treasury Regulations promulgated thereunder, so as to not be treated as the grant of a new stock right or change in the form of payment for purposes of Section 409A of the Code. FNB and UBNC agree to take all reasonable and necessary steps to effect the provisions of this Section 1.6(a). Promptly following the Effective Time, FNB shall issue to each holder of each outstanding UBNC Stock Option that has been assumed by FNB a document evidencing the conversion and assumption of such UBNC Stock Option by FNB pursuant to this Section 1.6(a).

(ii)    With respect to each UBNC Stock Option that, pursuant to the applicable award agreement and UBNC Equity Plan, become fully vested as of immediately prior to the Effective Time, all holders of such UBNC Stock Options that are vested prior to the Effective Time shall be afforded a reasonable opportunity to exercise such UBNC Stock Option, with such exercise effective immediately prior, and conditioned upon, to the Effective Time and with any such elections due not later than five (5) business days prior to the Effective Time (any UBNC Stock Option that is so exercised, an “Exercised UBNC Stock Option”). Any shares of UBNC Common Stock issued or due as a result of any such exercise of an Exercised UBNC Stock Option (“Option Shares”) shall be converted, as of the Effective Time, into the right to receive, without interest, the Merger Consideration payable pursuant to Section 1.4 and shall entitle the holder thereof to be treated for the purposes of this Agreement in the same manner as all other holders of shares of UBNC Common Stock outstanding immediately prior to the Effective Time.

(b)    UBNC Restricted Stock. Immediately prior to the Effective Time, each restricted stock award in respect of a share of UBNC Common Stock granted under a UBNC Equity Plan that is outstanding immediately prior to the Effective Time (a “UBNC Restricted Stock Award” and, together with the UBNC Stock Options, the “UBNC Equity Awards”) shall, if and to the extent provided pursuant to the terms of the applicable agreement and UBNC Equity Plan, become fully vested immediately prior to the Effective Time and each share of UBNC Common Stock issued pursuant to a UBNC Restricted Stock Award issued and outstanding immediately prior to the Effective Time shall be converted, as of the Effective Time, into the right to receive, without interest, the Merger Consideration payable pursuant to Section 1.4 and shall entitle the holder thereof to be treated for the purposes of this Agreement in the same manner as all other holders of shares of UBNC Common Stock outstanding immediately prior to the Effective Time. At the Effective Time, any other UBNC Restricted Stock Awards that have not fully vested pursuant to the terms of the applicable award agreement and UBNC Equity Plan shall be converted into FNB restricted stock awards (and adjusted so that its holder will be entitled to receive upon vesting of such award that number of whole shares of FNB Common Stock (rounded down to the nearest whole share) equal to the product of (A) the number of shares of UBNC Common Stock subject to such UBNC Restricted Stock Award immediately prior to the Effective Time multiplied by (B) the Exchange Ratio) and shall otherwise continue to have, and shall be subject to, the same terms and conditions as applicable immediately prior to the Effective Time except as provided in this Section 1.6(b) and that from and after the Effective Time, FNB and the Compensation Committee of the FNB Board of Directors, including, if applicable, the entire Board of Directors of FNB, shall be substituted for UBNC and the Compensation Committee of the Board of Directors of UBNC, including, if applicable, the entire Board of Directors of UBNC, administering such UBNC Equity Plans.

1.7    Articles of Incorporation and Bylaws of the Surviving Company. At the Effective Time, the FNB Charter, 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 its terms and applicable Law. At the Effective Time, the FNB Bylaws, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Company until thereafter amended in accordance with its terms and applicable Law.

1.8    The Bank Merger. As soon as practicable after the execution of this Agreement, UBNC and FNB shall cause Union Bank (“UBNC Bank”), a North Carolina state-chartered bank and a wholly owned subsidiary of UBNC, and First National Bank of Pennsylvania (“FNB Bank”), a national banking association and wholly owned subsidiary of FNB, respectively, to enter into a bank merger agreement substantially in the form attached to this Agreement as Exhibit B (the “Bank Merger Agreement”), which provides for the merger of UBNC Bank with and into FNB Bank, with FNB Bank being the surviving entity (the “Bank Merger”). Prior to filing applications for the Requisite Regulatory Approvals: (i) (A) UBNC shall cause UBNC Bank to obtain approval from the Board of Directors of UBNC Bank for the Bank Merger Agreement, (B) UBNC, as the sole shareholder of UBNC Bank, shall approve the Bank Merger Agreement and (C) UBNC shall cause the Bank Merger Agreement to be duly executed by UBNC Bank and delivered to FNB; and (ii) (A) FNB shall cause FNB Bank to obtain approval from the Board of Directors of FNB Bank for the Bank Merger Agreement, (B) FNB, as the sole shareholder of FNB Bank, shall approve the Bank Merger Agreement and (C) FNB shall cause the Bank Merger Agreement to be duly executed by FNB Bank and delivered to UBNC. Prior to the Effective Time, UBNC shall cause UBNC Bank, and FNB shall cause FNB Bank, to execute such articles or statement of merger and such other documents and certificates as are necessary or desirable to make the Bank Merger effective (the “Bank Merger Certificates”) immediately following the Effective Time.

1.9    Right to Revise Structure. At FNB’s election delivered to UBNC in writing, FNB may at any time alternatively structure the Merger so that any direct or indirect wholly owned subsidiary of FNB is merged with and into UBNC; provided, however, that no such change shall (i) alter or change the amount or kind of the Merger Consideration or treatment of the shares UBNC Common Stock or UBNC Equity Awards provided for in this Agreement, (ii) prevent the parties from obtaining the opinions of counsel referred to in Sections 7.2(d) and 7.3(d) or adversely affect the Tax treatment for UBNC’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 impede or delay consummation of the transactions this Agreement contemplates. In the event of such an election, the parties agree to execute an appropriate amendment to this Agreement (to the extent such amendment only changes the method of effecting the business combination and does not substantively affect this Agreement or the rights and obligations of the parties or their respective shareholders) in order to reflect such election.

ARTICLE 2

EXCHANGE OF SHARES

2.1    FNB to Make Merger Consideration Available. At or as promptly as practicable following the Effective Time, FNB shall deposit, or shall cause to be deposited, with Broadridge Corporate Issuer Solutions, Inc., as exchange agent (“Exchange Agent”), for the benefit of the holders of Certificates and 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 UBNC Common Stock outstanding immediately prior to the Effective Time of the Merger and (ii) immediately available funds sufficient in amount to pay (x) any dividends or distributions payable in accordance with Section 2.2(b)(i), and (y) 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 2.2(a) in exchange for outstanding shares of UBNC Common Stock (such immediately available funds and book entry shares of FNB Common Stock, collectively being referred to as the “Exchange Fund”). The Exchange Agent shall invest any cash included in the Exchange Fund as directed by FNB, provided that no such investment or losses thereon shall affect the amounts payable to the holders of Certificates.

2.2    Exchange Shares.

(a)    As soon as practicable after the Effective Time, but in no event later than seven (7) business days thereafter, the Exchange Agent shall mail to each holder of record of UBNC Common Stock a letter of transmittal in customary form as prepared by FNB and reasonably acceptable to UBNC (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 UBNC 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 UBNC 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 if in physical form, together with duly executed transmittal materials to the Exchange Agent, shall, upon acceptance thereof, be entitled to: (i) book entry shares representing FNB Common Stock into which the shares UBNC 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. Subject to applicable Law, until surrendered as contemplated by this Section 2.2, each Certificate representing shares of UBNC 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 UBNC Common Stock represented by such Certificate or Certificates shall have been converted pursuant to this Agreement, any dividends or distributions to which such

- 7 -

holder is entitled pursuant to Section 2.2(b). Subject to applicable Law, 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 UBNC 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 UBNC in respect of shares of UBNC 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(f) 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)    After the Effective Time, there shall be no transfers on the stock transfer books of UBNC of the shares of UBNC Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of shares of UBNC Common Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates are presented to FNB for any reason, they shall be cancelled and exchanged as provided in this Agreement. 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 UBNC Common Stock (or the provision of customary affidavits and indemnification for lost or mutilated Certificates in accordance with the terms hereof) and the letter of transmittal, shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of UBNC Common Stock.

- 8 -

(d)    Any portion of the Exchange Fund, including any interest thereon, that remains undistributed to the shareholders of UBNC following the passage of twelve (12) months after the Effective Time of the Merger shall be delivered to FNB, upon demand, and any former holders of UBNC Common Stock 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).

(e)    Neither UBNC nor FNB shall be liable to any holder of shares of UBNC 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.

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

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 or on 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 to give holders of UBNC Common Stock the same economic effect as contemplated by this Agreement prior to such event, 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 UBNC Common Stock or UBNC Equity Awards 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 UBNC Common Stock or UBNC Equity Awards in respect of whom such deduction and withholding was made by the Exchange Agent or FNB, as the case may be.

None of UBNC and the UBNC Subsidiaries nor, to UBNC’s knowledge, 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 likely to subject UBNC, any of the UBNC Subsidiaries or any Person that UBNC or any of the UBNC Subsidiaries has an obligation to indemnify, to any material Tax or penalty imposed under Section 4975 of the Code or Section 502 of ERISA.

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

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

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 the FNB Benefit Plan is entitled to rely on a favorable advisory or opinion letter issued by the IRS with respect to the preapproved plan document adopted in accordance with the requirements for such reliance.

None of FNB and its Subsidiaries nor, to FNB’s knowledge, 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 likely 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)    Each FNB Benefit Plan that constitutes in any part a nonqualified deferred compensation plan within the meaning of Section 409A of the Code has been operated and maintained in all material respects in operational and documentary compliance with Section 409A of the Code and applicable guidance thereunder.

- 37 -

(f)    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.

(g)    (i) No FNB Benefit Plan is a Multiemployer Plan or a Multiple Employer Plan, (ii) none of FNB nor any of its ERISA Affiliates has, at any time during the last six (6) years, contributed to or been obligated to contribute to any Multiemployer Plan or Multiple Employer Plan and (iii) none of FNB nor any of its ERISA Affiliates has incurred, during the last six (6) years, any Withdrawal Liability that has not been satisfied in full.

Without limiting the generality of the foregoing, neither FNB nor any of its ERISA Affiliates, has engaged in any transaction described in Sections 4069, 4204 or 4212 of ERISA.

ADDITIONAL AGREEMENTS

6.1    Regulatory Matters.

(a)    FNB agrees to prepare and file, as soon as practicable (but in any case, within forty-five (45) calendar days of the date of this Agreement), the Registration Statement with the SEC in connection with the issuance of FNB Common Stock in the Merger including the Proxy Statement and prospectus and other proxy solicitation materials of UBNC and FNB constituting a part thereof and all related documents. UBNC shall prepare and furnish to FNB such information relating to it and its Subsidiaries, directors, officers and shareholders as may be reasonably required in connection with the above referenced documents based on its knowledge of and access to the information required for said documents. UBNC and its legal, financial and accounting advisors shall have the right to review in advance and approve, which approval shall not be unreasonably withheld, conditioned or delayed, such Registration Statement prior to its filing. UBNC agrees to cooperate with FNB and FNB’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and independent auditor in connection with the Registration Statement and the Proxy Statement. Each of UBNC and FNB agrees to use its reasonable best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after the filing thereof. FNB also agrees to use its reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions this Agreement contemplates. After the SEC has declared the Registration Statement effective under the Securities Act, UBNC shall promptly mail the Proxy Statement to its shareholders, and the expenses in connection therewith shall be borne in accordance with Section 9.3(a).

- 51 -

(b)    Each of UBNC 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 UBNC 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 at the dates of mailing to the UBNC shareholders 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, in the light of the circumstances under which such statements were made, not misleading. Each of UBNC and FNB further agrees 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 UBNC.

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

(d)    The parties shall cooperate with each other and use their respective reasonable best efforts to promptly (but in any case, within forty-five (45) calendar days of the date of this Agreement) 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 the Bank 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. UBNC 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 UBNC 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. In furtherance and not in limitation of the foregoing, each of FNB and

- 52 -

UBNC shall use their respective reasonable best efforts to (i) avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the Closing, and (ii) avoid or eliminate each and every impediment so as to enable the Closing to occur as soon as possible. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to require FNB or UBNC 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 Regulatory Agencies or Governmental Entities that would reasonably be likely to have a Material Adverse Effect on the Surviving Company after giving effect to the Merger, after the Effective Time (a “Materially Burdensome Regulatory Condition”). In addition, UBNC 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 UBNC and FNB following consummation of the Merger.

(e)    Each of FNB and UBNC 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, UBNC 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 UBNC shall promptly provide each other with any written communications received from any Regulatory Agency or Governmental Entity with respect to the transactions contemplated by this Agreement and will promptly advise the other upon receiving any oral communication with respect to the transactions contemplated by this Agreement from any Regulatory Agency or Governmental Entity whose consent or approval is required for consummation of the transactions this Agreement contemplates.

(g)    UBNC 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, conditioned or delayed; 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 NCCOB or the NYSE. In addition, the Chief Executive Officers of UBNC and FNB shall be permitted to respond to appropriate questions about the Merger from the press. UBNC 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.

- 53 -

6.2    Access to Information.

(a)    Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each of UBNC and FNB shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel and other representatives of the other, reasonable access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records, and, during such period, the parties shall, and shall cause their respective Subsidiaries to, make available to the other party all other information concerning its business, properties and personnel as the other party may reasonably request. Each party shall use commercially reasonable efforts to minimize any interference with the other party’s regular business operations during any such access. UBNC shall, and shall cause each of its Subsidiaries to, provide to FNB a copy of each report, schedule and other document filed or received by it during such period pursuant to the requirements of federal or state banking laws other than reports or documents that such party is not permitted to disclose under applicable Law. Neither UBNC nor FNB nor any of their Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would be likely to jeopardize or prejudice the attorney-client privilege or attorney work-product protection of such party or its Subsidiaries or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement, including laws relating to confidential supervisory information. The parties shall make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply to the extent possible in light of those restrictions.

(b)    All information and materials provided pursuant to this Agreement shall be subject to the provisions of the confidentiality agreement, dated March 29, 2022, between UBNC and FNB (the “Confidentiality Agreement”).

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

6.3    Shareholder Approval.

UBNC shall call a meeting of its shareholders for the purpose of obtaining the Requisite UBNC Vote (the “UBNC 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. Subject to Section 6.11(b), UBNC shall (i) through the Board of Directors of UBNC, recommend that the shareholders of UBNC approve and adopt this Agreement, and approve the Merger and the other transactions this Agreement contemplates, (ii) include such recommendation in the Proxy Statement (the “UBNC Recommendation”), and (iii) subject to the fiduciary duties of the Board of Directors of UBNC, use its reasonable best efforts to obtain from its shareholders a vote approving and adopting the Merger and this Agreement. Without limiting the generality of the foregoing, UBNC’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 UBNC of any Acquisition Proposal or by any change in the UBNC Recommendation.

6.4    Reasonable Best Efforts; Cooperation. Each of UBNC and FNB agrees to exercise good faith and use its 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.

- 54 -

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

6.6    Benefit Plans.

(a)    As soon as administratively practicable after the Effective Time, FNB shall take all reasonable action so that employees of UBNC and the UBNC 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 UBNC and the UBNC Subsidiaries in the FNB Eligible Plans may occur at different times with respect to different plans, provided that coverage shall be continued under corresponding UBNC 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 UBNC under any discretionary equity compensation plan of FNB or to provide the same level of (or any) employer contributions or other benefit subsidies as UBNC or the UBNC Subsidiaries have provided. Notwithstanding the foregoing, during the period commencing at the Effective Time and ending on the first anniversary thereof, FNB or its Subsidiaries shall provide severance payments and benefits to each employee of UBNC and the UBNC Subsidiaries (as of immediately prior to the Effective Time) that are no less favorable than the severance payments and benefits provided by FNB and its Subsidiaries to their similarly situated employees, as of the date hereof and as further described in Section 6.6(a) of the FNB Disclosure Schedule.

(b)    FNB shall cause each FNB Eligible Plan in which employees of UBNC and the UBNC 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 UBNC and the UBNC Subsidiaries to the same extent as such service was credited for such purpose by UBNC or the UBNC Subsidiaries, and, solely for purposes of FNB’s severance and vacation plans, policies and 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 UBNC Benefit Plans that correspond to FNB Eligible Plans until employees of UBNC and the UBNC Subsidiaries are included in such FNB Eligible Plans, nothing in this Agreement shall limit the ability of FNB to amend or terminate any of the UBNC Benefit Plans in accordance with and to the extent permitted by their terms.

(c)    At and following the Effective Time, FNB and the Surviving Company shall honor and continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of UBNC and the UBNC Subsidiaries and current and former directors of UBNC and the UBNC Subsidiaries existing as of the Closing Date under any UBNC Benefit Plan.

- 55 -

(d)    At such time as employees of UBNC and the UBNC 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 were satisfied or waived under the analogous UBNC Benefit Plan, (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 UBNC Benefit Plan prior to the Effective Time and (iii) provide each such employee of UBNC and the UBNC Subsidiaries and his or her eligible dependents with credit for any co-payments or coinsurance and deductibles paid prior to the Effective Time under an UBNC Benefit Plan (to the same extent that such credit was given under the analogous UBNC Benefit Plan prior to the Effective Time) in satisfying any applicable deductible, co-payment, coinsurance or maximum out-of-pocket requirements under any medical, dental or health plan of FNB or its Subsidiaries.

(e)    UBNC shall adopt such Board resolutions and take such other action as FNB may reasonably request at least thirty (30) days prior to the Effective Time to cause all 401(k) Plans to be terminated immediately prior to the Effective Time (the “Plan Termination Date”) and the accounts of all participants and beneficiaries in the 401(k) Plans as of the Plan Termination Date to become fully vested as of the Plan Termination Date. 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 that the termination of the 401(k) Plans 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 adopting such amendments to the 401(k) Plans 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 401(k) Plans upon its termination, the account balances in the 401(k) Plans shall 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 (or, where no direction is received, to an individual retirement account as an automatic rollover). The Surviving Company shall take all other actions necessary to complete the termination of the 401(k) Plans, including filing a Final Form 5500, that arise after the Effective Time. FNB agrees, to the extent permitted by applicable Law, to permit the participants in the 401(k) Plans who become employees of FNB or its Subsidiaries to roll over their account balances in the 401(k) Plans and loans from the 401(k) Plans to the F.N.B. Corporation Progress Savings 401(k) Plan. Notwithstanding anything in Section 6.6(a) to the contrary, employees of UBNC or any UBNC 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) Plans.

(f)    Immediately prior to the Effective Time, UBNC shall, at the written request of FNB, (i) freeze or terminate each other UBNC Benefit Plan as requested by FNB, including without limitation, any non-qualified deferred compensation plans and make appropriate distributions therefrom; and (ii) freeze all post-retirement benefits available under the UBNC Benefit Plans, provided that FNB shall not request UBNC to freeze or terminate any UBNC Benefit Plan that is continued in accordance with FNB’s commitment, as set forth in Section 6.6(b).

- 56 -

(g)    UBNC 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 UBNC Benefit Plan to be removed effective as of the Effective Time and to appoint FNB, 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.

(h)    Nothing contained in this Agreement is intended to (i) be treated as an amendment of any UBNC Benefit Plan; (ii) prevent FNB, UBNC or any of their successors or Affiliates, after the Effective Time, from terminating the employment of any UBNC employee who remains employed with UBNC or any of the UBNC Subsidiaries; or (iii) create any third party beneficiary rights in any employee of UBNC or any of the UBNC Subsidiaries, or any beneficiary or dependent thereof, with respect to the compensation, terms and conditions of employment and/or benefits that may be provided to any UBNC employee by FNB, UBNC or any of their successors or Affiliates or under any benefit plan which FNB, UBNC or any of their successors or Affiliates may maintain.

(i)    As soon as practicable following the Effective Time, FNB shall file a registration statement on Form S-8 (or any successor or other appropriate forms) with the SEC with respect to each of the UBNC Equity Plans assumed by FNB and the shares of FNB Common Stock subject to the assumed UBNC Stock Options that were originally granted under such UBNC Equity Plans. FNB shall use its commercially reasonable efforts to maintain the effectiveness of each such registration statement (and maintain the current status of the prospectus or prospectuses associated therewith) for so long as such assumed UBNC Stock Options remain outstanding.

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 UBNC or any of the UBNC Subsidiaries or who is or was serving at the request of UBNC or any of the UBNC Subsidiaries as a director, officer, employee, trustee or fiduciary of another Person (the “Indemnified Parties”), is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he or she is or was a director or officer of UBNC or any of the UBNC Subsidiaries or was serving at the request of the UBNC or any of the UBNC Subsidiaries as a director, officer, employee, trustee or fiduciary of another Person or (ii) this Agreement or any of the transactions this Agreement contemplates, whether asserted or arising before or after the Effective Time, the parties shall cooperate and use their best efforts to defend against such Claim and respond thereto. From and after the Effective Time, FNB shall, and shall cause the Surviving Company to, (A) indemnify and hold harmless, as and to the fullest extent currently provided under applicable Law, the UBNC Articles and the UBNC 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, and judgments, fines and amounts paid in settlement in connection with any such threatened or actual Claim and

- 57 -

(B) advance expenses as incurred (including in advance of the final disposition of any Claim) by such Indemnified Party to the fullest extent permitted by applicable Law; provided that the Indemnified Party to whom expenses are advanced provides an undertaking (in a reasonable and customary form) if required by applicable Law to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification.

(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 any determination required to be made with respect to whether an Indemnified Party’s conduct complies with the standards set forth under applicable Law, the UBNC Articles or the UBNC 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 Party and reasonably acceptable to FNB; and, provided further that nothing in this Section 6.7(b) shall impair any rights or obligations of any current or former director or officer of UBNC or its Subsidiaries, including pursuant to the respective organizational documents of UBNC, or its Subsidiaries, under applicable Law or otherwise.

(c)    Prior to the Effective Time, FNB shall obtain and thereafter maintain for a period of six (6) years following the Effective Time, directors’ and officers’ liability insurance and fiduciary liability insurance policies covering the Indemnified Parties who as of the Effective Time are covered by UBNC’s directors’ and officers’ liability insurance or fiduciary liability insurance policies, in respect of acts or omissions occurring at or prior to the Effective Time, including the transactions this Agreement contemplates, provided that the policies must be of at least the same coverage amounts (as set forth on Section 3.20 of the UBNC Disclosure Schedule) and contain coverage terms and conditions and that are not less advantageous than such policy of UBNC. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if a prepaid policy has been obtained prior to the Effective Time from an insurer or insurers selected by FNB in consultation with UBNC that has or have an insurer financial strength rating by A.M. Best Co. of at least “A”, which policy provides the Indemnified Parties with coverage, from the Effective Time to the sixth (6^th) anniversary of the Effective Time, including in respect of the transactions this Agreement contemplates, on terms that are no less advantageous to the Indemnified Parties than UBNC’s directors’ and officers’ liability insurance policy 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. However, in no event shall FNB be required to expend, on an annual basis, an amount in excess of 300% of the annual premium paid by UBNC for such insurance (the “Insurance Amount”) on the date of this Agreement, 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 reasonable best efforts to obtain policies containing coverage amounts, terms and conditions that are the most advantageous for the Indemnified Parties as is available for the maximum Insurance Amount.

(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 the Surviving Company, or any of its successors or assigns,

- 58 -

consolidates with or merges into any other entity and is not the continuing or surviving entity of such consolidation or merger, transfers all or substantially all of its assets or deposits to any other entity or engages in any similar transaction, then in each case, the Surviving Company will cause proper provision to be made so that the successors and assigns of the Surviving Company will expressly assume the obligations of the Surviving Company 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 UBNC, 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 UBNC 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 or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article 7; provided, further, that a failure to comply with this Section 6.9 shall not constitute the failure of any condition set forth in Article 7 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 7 to be satisfied.

6.10    Dividends. Without the prior written consent of FNB, UBNC shall not declare or pay any dividend in respect of shares of UBNC Common Stock other than UBNC’s regular semi-annual cash dividend of $0.11 per share of UBNC Common Stock.

6.11    Certain Actions.

(a)    From the date of this Agreement through the Effective Time, except as otherwise permitted by this Section 6.11, UBNC will not, and will not authorize or permit any of its directors, officers, agents, employees, investment bankers, attorneys, accountants, advisors, agents, Affiliates or representatives (collectively, “UBNC Representatives”) to, directly or indirectly, (i) initiate, solicit, knowingly encourage or take any action to facilitate, including by way of furnishing information, any Acquisition Proposal or any inquiries with respect to or the making of any Acquisition Proposal, (ii) enter into or participate in any discussions or negotiations with, furnish any information relating to UBNC or any of the UBNC Subsidiaries or afford access to the business, properties, assets, books or records of UBNC or any of the UBNC Subsidiaries, to otherwise cooperate in any way with, or knowingly assist, participate in, facilitate or encourage any effort by any Third Party that is seeking to make, or has made, an Acquisition Proposal or (iii) except in accordance with Section 8.1(g), approve, endorse or recommend or enter into any letter of intent or similar document or any contract, agreement or commitment contemplating or otherwise relating to an Acquisition Proposal.

(b)    Notwithstanding anything in this Agreement to the contrary, UBNC and its Board of Directors shall be permitted: (i) to comply with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act with regard to an Acquisition Proposal provided that the Board of Directors of UBNC shall not withdraw or modify in a manner adverse to FNB the UBNC Recommendation except as set forth in subsection (iii) below, (ii) to engage in any discussions or negotiations with, and provide any information to, any Third Party in response to a bona fide Acquisition Proposal by any such Third Party, if (x) UBNC’s Board of Directors concludes in good faith, based on the information then available after consultation with outside counsel and, with respect to financial matters, its financial advisor that failure to do so would be reasonably likely to violate their fiduciary duties under applicable Law and that such Acquisition Proposal could reasonably be expected to lead to a Superior Proposal, (y) prior to providing any information or data to any Third Party in connection with such Acquisition Proposal by any such Third Party, UBNC’s Board of Directors receives from such Third Party an executed confidentiality agreement, which confidentiality terms shall be no less favorable to UBNC than those contained in the Confidentiality Agreement and (iii) to withdraw, modify, qualify in a manner adverse to FNB, condition or refuse to make the UBNC Recommendation (the “Change in UBNC Recommendation”) if UBNC’s Board of Directors concludes in good faith, based on the information then available after consultation with outside counsel and, with respect to financial matters, its financial advisor, that failure to do so would be reasonably likely to violate their fiduciary duties under applicable Law. Notwithstanding any Change in UBNC Recommendation, this Agreement shall be submitted to the shareholders of UBNC at the UBNC Shareholders’ Meeting for the purpose of voting on the approval of this Agreement and nothing contained herein shall be deemed to relieve UBNC of such obligation; provided, however, that if the Board of Directors of UBNC shall have effected a Change in UBNC Recommendation, then the Board of Directors of UBNC may submit this Agreement to UBNC’s shareholders without recommendation (although the resolutions adopting this Agreement as of the date hereof may not be rescinded), in which event the Board of Directors of UBNC may communicate the basis for its lack of a recommendation to UBNC’s shareholders in the Proxy Statement or an appropriate amendment or supplement thereto to the extent required by applicable Law.

(ii)    The term “Superior Proposal” means any bona fide, unsolicited written Acquisition Proposal made by a Third Party to acquire more than 50% of the combined voting power of the shares of UBNC Common Stock then outstanding or all or substantially all of UBNC’s consolidated assets for consideration consisting of cash and/or securities that is on terms that the Board of Directors of UBNC in good faith concludes, based on the information then available after consultation with its financial advisor and outside counsel, taking into account, among other things, all legal, financial, regulatory and other aspects of the proposal and the Person making the proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation, (A) is on terms that the Board of Directors of UBNC in its good faith judgment believes to be more favorable to UBNC than the Merger, (B) for which financing, to the extent required, is then fully committed or reasonably determined to be available by the Board of Directors of UBNC and (C) is reasonably capable of being completed.

(iii)    For purposes of this Section 6.11, “Third Party” means any person as defined in Section 13(d) of the Exchange Act other than FNB or its Affiliates.

(f)    If a Payment Event occurs, UBNC shall pay FNB by wire transfer of immediately available funds, within three (3) business days following such Payment Event, a fee of $4.0 million (the “Break-up Fee”), provided, however, that if a Payment Event occurs, UBNC shall have no obligation to pay FNB’s expenses under Section 9.3(b) and any amounts previously paid pursuant to Section 9.3(b) shall be credited against the Break-up Fee.

FNB and UBNC shall each use its reasonable best efforts not to take or cause to be taken any action that would cause to be untrue (or fail to take or cause not to be taken any action which inaction would cause to be untrue) any of the representations included in the certificates described in this Section 6.13.

6.14    Rule 16b-3. Prior to the Effective Time, FNB and UBNC shall take all steps as may be necessary or appropriate to cause the transactions contemplated by Article 1 and any other dispositions of UBNC Equity Awards (including derivative securities) or acquisitions of equity securities of FNB in connection with the consummation of the transactions contemplated by this Agreement to be exempt under Rule 16b-3 promulgated under the Exchange Act.

In furtherance of such planning, UBNC shall take all such commercially reasonable actions as may be required so that its third-party processer will be able, from and after the Effective Time and

- 63 -

prior to Informational Systems Conversion, to support ongoing deposit and loan transaction activity and related financial activity of UBNC Bank including, without limitation, providing a general ledger transaction file and secondary financial statements on a daily basis, reflecting the deposit and loan activity of UBNC Bank from the prior business day. FNB shall reimburse UBNC for all documented out-of-pocket costs and expenses incurred by UBNC as a result of actions taken at the direction of FNB pursuant to this Section 6.16.

9.5    Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The UBNC Disclosure Schedule and the FNB Disclosure Schedule, as well as all other schedules and all exhibits to this Agreement, shall be deemed part of this Agreement and included in any reference to this Agreement. Any matter disclosed pursuant to any section of either Disclosure Schedule shall be deemed disclosed for purposes of any other section of Article 3 or Article 4, respectively, to the extent that applicability of the disclosure to such other section is reasonably apparent on the face, notwithstanding the absence of a specific cross-reference, of such disclosure. No item is required to be set forth in either Disclosure Schedule as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect. The mere inclusion of an item in either Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by either party that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect, or that any breach or violation of applicable Laws or any contract exists or has actually occurred. This Agreement shall not be interpreted or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable Law. As used in this Agreement, “knowledge” means the actual knowledge as of the date referenced of executive officers of the applicable party following reasonable inquiry of persons within their organization and its Subsidiaries who would be reasonably expected to be knowledgeable about the relevant subject matter. As used herein, (i) “business day” means any day other than a Saturday, a Sunday or a day on which banks in Raleigh, North Carolina or Pittsburgh, Pennsylvania are authorized by law or executive order to be closed, (ii) the term “made available” means any document or other information that was (a) provided by one party or its representatives to the other party or its representatives prior to the date hereof, (b) included in the virtual data room of a party prior to the date hereof or (c) filed by a party with the SEC and publicly available on EDGAR prior to the date hereof, (iii) references to “the date hereof” shall mean the date of this Agreement, (iv) the word “or” is not exclusive and (v) terms defined in the singular have a comparable meaning when used in the plural, and vice versa.

9.6    Counterparts. This Agreement, any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, may be executed in two or more counterparts, including by facsimile or other electronic means, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties and delivered to the other party, it being understood that each party need not sign the same counterpart. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or e-mail delivery of a “.pdf”

- 73 -

format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.

9.7    Entire Agreement. This Agreement, including the documents and the instruments referred to in this Agreement, together with the Confidentiality Agreement, constitutes the entire agreement between the parties and supersedes all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter of this Agreement.

(a)    This Agreement shall be governed and construed in accordance with the laws of the State of Delaware, without giving effect to any applicable conflicts of law.

(b)    Each of the parties to this Agreement agrees that it shall bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions that are contemplated by this Agreement exclusively in any federal or state court sitting in Wilmington, Delaware (the “Chosen Courts”), and solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party hereto and (iv) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 9.4.

(c)    EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.8.

(d)    Each party agrees that irreparable damage would occur if any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached. Accordingly, the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement or to enforce

- 74 -

specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger), in addition to any other remedy to which they are entitled at law or in equity. Each of the parties further waives (i) any defense in any action for specific performance that a remedy at law would be adequate and (ii) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

9.9    Severability. Any term or provision of this Agreement that is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable. In all such cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision that, insofar as practicable, implements the original purposes and intents of this Agreement.

9.10    Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by either of the parties, whether by operation of law or otherwise, without the prior written consent of the other party. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by each of the parties and their respective successors and assigns. Except as otherwise specifically provided in Section 6.7(d), this Agreement, including the documents and instruments referred to in this Agreement, is not intended to and does not confer upon any person other than the parties to this Agreement any rights or remedies under this Agreement, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Exhibit A

VOTING AGREEMENT

May 31, 2022

F.N.B. Corporation

One North Shore Center

12 Federal Street

Pittsburgh, PA 15212

Ladies and Gentlemen:

Concurrently with the execution of this letter agreement (“Voting Agreement”), F.N.B. Corporation, a Pennsylvania corporation (“FNB”), and UB Bancorp, a North Carolina corporation (“UBNC”), are entering into an Agreement and Plan of Merger, of even date herewith (the “Merger Agreement”), whereby UBNC will merge with and into FNB (the “Merger”) and shareholders of UBNC will receive the Merger Consideration as set forth in the Merger Agreement, subject to the closing of the Merger. All defined terms used but not defined herein shall have the meanings ascribed thereto in the Merger Agreement.

A condition to FNB’s interest in entering into 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, except as noted on Appendix A, I have, and at all times during the term of this Voting Agreement will have (subject to paragraphs (d) and (g) hereof), 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, no par value, of UBNC (the “UBNC Common Stock”), that is set forth on Appendix A hereto. Except as noted on Appendix A, 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). Except as noted on Appendix A, none of the securities listed on Appendix A is 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 as set forth on Appendix A, I do not beneficially own any (i) shares of capital stock or voting securities of UBNC, (ii) securities of UBNC convertible into or exchangeable for shares of capital stock or voting securities of UBNC or (iii) options or other rights to acquire from UBNC any shares of capital stock, voting securities or securities convertible into or exchangeable for capital stock or voting securities of UBNC. The UBNC Common Stock listed on Appendix A, together with all UBNC Common Stock that I subsequently acquire during the term of this Voting Agreement, including through the issuance of shares of UBNC Common Stock as part of UBNC’s director compensation program or the exercise of any stock options, warrants or similar instruments, are referred to herein as the “Shares”.

Page 2

(c) During the term of this Voting Agreement, at the UBNC Shareholders Meeting and at any other meeting of UBNC shareholders, however called, and on every action or approval by written consent of shareholders of UBNC, I will vote or cause to be voted all Shares over which I have sole voting power, and I will use my commercially 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, on or prior to the record date for the UBNC Shareholders Meeting (as defined in the Merger 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 my commercially 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 UBNC shall not be bound by any attempted sale of any UBNC Common Stock over which I have sole voting and dispositive power, and UBNC’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 to my spouse, ancestors or descendants or other transfers solely for estate planning purposes; 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.

I am signing this Voting Agreement solely in my capacity as a shareholder of UBNC and not in any other capacity, such as a director or officer of UBNC 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 UBNC Common Stock and (b) nothing herein shall be construed to limit or affect any action or inaction by me or any of my representatives, as applicable, in serving on UBNC’s Board of Directors or as an officer of UBNC, in acting in my capacity as a director, officer or fiduciary of UBNC.

This Voting Agreement shall terminate and be of no further force and effect concurrently with, and automatically upon, the earliest to occur of (a) the favorable vote of the UBNC shareholders with respect to the approval of the Merger Agreement, (b) a Change in UBNC Recommendation (as defined in the Merger Agreement), (c) the Effective Time, (d) FNB and I enter into a written agreement to terminate this Voting Agreement, or (e) 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.

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 State of Delaware, without giving effect to the principles of conflicts of law thereof. I hereby irrevocably and unconditionally submit to the exclusive jurisdiction of any state or federal court sitting in Wilmington, Delaware, in any action or proceeding arising out of or relating to this letter.

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.
