THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is entered into as of the 9^th day of May, 2005 by and between UNITED FINANCIAL, INC., a North Carolina corporation and registered bank holding company (“United”), and FNB CORP., a North Carolina corporation and registered bank holding company (“FNB”);

WITNESSETH:

WHEREAS, the parties hereto have agreed that it is in their mutual best interests and in the best interests of their respective shareholders for United to be merged with and into FNB pursuant to a plan of merger (the “Plan of Merger”) in the form attached hereto as Schedule A, and the parties desire to provide for certain undertakings, conditions, representations, warranties and covenants in connection with the Merger (as defined in Section 1.1) and transactions contemplated hereby.

NOW, THEREFORE, in consideration of the premises, the mutual benefits to be derived from this Agreement, and of the representations, warranties, conditions, covenants and promises herein contained, and subject to the terms and conditions hereof, the parties hereto mutually agree as follows:

ARTICLE I. THE MERGER

1.1 Merger. Subject to the provisions of this Agreement and the Plan of Merger, as of the Effective Time (as defined in Section 1.12 hereof), United shall be merged with and into FNB (the “Merger”), the separate corporate existence of United shall cease and the corporate existence of FNB, as the surviving corporation in the Merger, shall continue under the laws of the State of North Carolina. FNB, as the surviving corporation in the Merger, is hereinafter sometimes referred to as the “Surviving Corporation.”

1.2 Effect of the Merger. At the Effective Time and by reason of the Merger, and in accordance with applicable law, all of the property, assets and rights of every kind and character of FNB and of United including, without limitation, its stock in its wholly owned subsidiary, Alamance Bank (“Alamance Bank”), and all real, personal or mixed property, all debts due on whatever account, all other choses in action and every other interest of or belonging to or due to United, whether tangible or intangible, shall vest in the Surviving Corporation, and the Surviving Corporation shall succeed to all the rights, privileges, immunities, powers, purposes and franchises of a public or private nature of United and FNB, all without any conveyance,

assignment or further act or deed; and the Surviving Corporation shall become responsible for all of the liabilities, duties and obligations of every kind, nature and description of United and FNB as of the Effective Time.

1.3 Articles of Incorporation, Bylaws and Management. The Articles of Incorporation and bylaws of FNB in effect at the Effective Time shall be the Articles of Incorporation and bylaws of the Surviving Corporation until thereafter amended in accordance with applicable laws. The officers and directors of FNB at the Effective Time shall continue to hold such offices and positions of the Surviving Corporation until removed as provided by law or until the election or appointment of their respective successors.

1.4 Conversion of Shares.

(a) United Stock. Except as otherwise provided herein, at the Effective Time, all rights of United’s shareholders with respect to all then outstanding shares of the common stock of United, $1.00 par value per share (“United Stock”), shall cease to exist, and the holders of shares of United Stock shall cease to be, and shall have no further rights as, shareholders of United. At the Effective Time, each such outstanding share of United Stock (except for shares held, other than in a fiduciary capacity or as a result of debts previously contracted, by United, FNB or any of their subsidiaries, which shall be canceled in the Merger, and for Dissenting Shares (as defined in Section 1.9)) shall be converted, without any action on the part of the holder of such shares, into the right to receive the Merger Consideration (as defined in Section 1.5) in accordance with this Article I. Following the Effective Time, certificates representing shares of United Stock outstanding at the Effective Time shall evidence only the right of the registered holder thereof to receive, and may be exchanged for, the Merger Consideration.

(b) Outstanding FNB Stock. Each share of common stock of FNB, par value $2.50 per share (“FNB Stock”), issued and outstanding immediately prior to the Effective Time shall continue to be issued and outstanding and shall not be affected by the Merger.

1.5 Merger Consideration.

(a) Per Share Consideration. Subject to the provisions of this Article I, at the Effective Time each outstanding share of United Stock (except for shares held, other than in a fiduciary capacity or as a result of debts previously contracted, by United, FNB or any of their subsidiaries and for Dissenting Shares) shall cease to represent any interest (equity, shareholder or otherwise) in United and shall automatically be converted exclusively into the right to receive, at the election of the holder thereof, either: (A) $14.25 in cash, without interest; (B) 0.6828 shares (the “Exchange Ratio”) of FNB Stock; or (C) 35% of the cash amount set forth in clause (A) above and a number of shares of FNB Stock equal to 65% of the Exchange Ratio; provided, however, that a holder of United Stock may, pursuant to Section 1.6, make no election, in which case such shares of United Stock held by such holder shall be converted exclusively into the right to receive the consideration set forth in Section 1.6(e) below with respect to Non-Election Shares (as defined in Section 1.6(b)). The amount of cash into which shares of United Stock shall be converted pursuant to this Agreement is sometimes hereinafter referred to as “Cash Consideration,” and the number of shares of FNB Stock into which shares of United Stock shall

be converted pursuant to this Agreement is sometimes hereinafter referred to as “Stock Consideration.” The Cash Consideration and Stock Consideration are sometimes referred to herein collectively as the “Merger Consideration.” No share of United Stock, other than Dissenting Shares (as defined in Section 1.9), shall be deemed to be outstanding or have any rights other than those set forth in this Section 1.5(a) after the Effective Time. The Exchange Ratio is subject to possible adjustment in accordance with Section 1.5(c) below.

(b) Fractional Shares. Notwithstanding any other provision of this Agreement, each holder of shares of United Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of FNB Stock (after taking into account all certificates delivered by such holder under Sections 1.6(c) and 1.8(a) below and the elections made pursuant to Section 1.6) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of FNB Stock multiplied by the market value of one share of FNB Stock at the Effective Time. The market value of one share of FNB Stock at the Effective Time shall be the last sale price of FNB Stock on Nasdaq Stock Market, Inc. National Market System (“Nasdaq”) as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source selected by FNB, on the last trading day preceding the Effective Time. No such holder will be entitled to dividends, voting rights, or any other rights as a shareholder in respect of any fractional shares.

(c) Anti-Dilution Provisions. In the event FNB changes the number of shares of FNB Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, reclassification, combination, exchange of shares, or similar transaction with respect to such stock and the record date therefor (in the case of a stock dividend) or the effective date thereof (in the case of a stock split, recapitalization, reclassification, combination, exchange of shares, or similar transaction for which a record date is not established) shall be prior to the Effective Time, the Exchange Ratio shall be appropriately adjusted to reflect such change.

1.6 Election and Allocation Procedures.

(a) An election form (an “Election Form”) and other appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing United Stock shall pass, only upon proper delivery of such certificates to the Exchange Agent (as hereinafter defined) in such form as United and FNB shall mutually agree shall be mailed on the Mailing Date (as defined below) to each shareholder of record of United. The “Mailing Date” shall be the date on which proxy materials relating to the Merger are mailed to holders of shares of United Stock.

(b) Each Election Form shall entitle the holder of shares of United Stock (or the beneficial owner through appropriate and customary documentation and instructions) to (i) elect to receive the Cash Consideration for all of such holder’s shares (a “Cash Election”), (ii) elect to receive the Stock Consideration for all of such holder’s shares (a “Stock Election”), (iii) elect to receive Merger Consideration in accordance with clause (C) of the first sentence of Section 1.5(a) (a “Mixed Election”), or (iv) make no election or to indicate that such holder has no preference as to the receipt of the Cash Consideration or the Stock Consideration (a “Non-Election”). Shareholders of record of United who hold shares of United Stock as nominees,

trustees or in other representative capacities may submit multiple Election Forms, provided that such representative certifies that each such Election Form covers all the shares of United Stock held by that representative for a particular beneficial owner. Shares of United Stock in respect of which a Cash Election shall have been made are referred to herein as “Cash Election Shares.” Shares of United Stock in respect of which a Stock Election shall have been made are referred to herein as “Stock Election Shares.” Shares of United Stock in respect of which no election shall have been made are referred to as “Non-Election Shares.” The aggregate number of shares of United Stock with respect to which a Stock Election shall have been made is referred to herein as the “Stock Election Number.” Shares of United Stock with respect to which a Mixed Election shall have been made shall not be deemed either Stock Election Shares or Cash Election Shares, but shall in all events be converted into the right to receive the Merger Consideration as specified in subsection (e) of this Section 1.6.

(c) To be effective, a properly completed Election Form shall be submitted to the Exchange Agent on or before 5:00 p.m. North Carolina time on the last business day prior to the date of the shareholders’ meeting contemplated by Section 4.3(a) (or such other time and date as United and FNB may mutually agree) (the “Election Deadline”). An election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by one or more certificates (or customary affidavits and, if required by FNB pursuant to Section 1.8(b), indemnification regarding the loss or destruction of such certificates or the guaranteed delivery of such certificates) representing all shares of United Stock covered by such Election Form, together with duly executed transmittal materials included with the Election Form. Any United shareholder may at any time prior to the Election Deadline change his or her election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised Election Form. Any United shareholder may, at any time prior to the Election Deadline, revoke his or her election by written notice received by the Exchange Agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her certificates, or of the guarantee of delivery of such certificates, previously deposited with the Exchange Agent. All elections shall be revoked automatically if the Exchange Agent is notified in writing by FNB and United that this Agreement has been terminated. If a United shareholder either (i) does not submit a properly completed Election Form by the Election Deadline, or (ii) revokes its Election Form prior to the Election Deadline, the shares of United Stock held by such shareholder shall be designated Non-Election Shares. FNB shall cause the certificates representing United Stock described in clause (ii) above to be promptly returned without charge to the person submitting the Election Form upon written request to that effect from the person who submitted the Election Form. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in any Election Form, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive.

(d) Notwithstanding any other provision contained in this Agreement, 65% (the “Stock Conversion Number”) of the total number of shares of United Stock outstanding at the Effective Time to be converted into Merger Consideration pursuant to Section 1.5(a) excluding such shares as may be subject to an effective Mixed Election (the “Adjustable Conversion Shares”), shall be converted into the Stock Consideration and the remaining

Adjustable Conversion Shares shall be converted into the Cash Consideration (in each case, excluding shares of United Stock to be canceled as provided in Section 1.4(a) and Dissenting Shares); provided, however, that for federal income tax purposes, it is intended that the Merger will qualify as a reorganization under the provisions of Section 368(a) of the Code and in order that the Merger will not fail to satisfy continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, as reasonably determined by counsel to FNB, FNB shall increase the number of Adjustable Conversion Shares that will be converted into the Stock Consideration and reduce the number of Adjustable Conversion Shares that will be converted into the right to receive the Cash Consideration.

(e) Within five business days after the later to occur of the Election Deadline or the Effective Time, FNB shall cause the Exchange Agent to effect the allocation among holders of United Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) In any event, all shares of United Stock with respect to which a Mixed Election shall have been made shall be converted into 35% of the amount of cash set forth in clause (A) of the first sentence of Section 1.5(a) and a number of shares of FNB Stock equal to 65% of the Exchange Ratio;

(ii) If the Stock Election Number exceeds the Stock Conversion Number, then all Cash Election Shares and all Non-Election Shares shall be converted into the right to receive the Cash Consideration, and each holder of Stock Election Shares will be entitled to receive the Stock Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (x) the number of Stock Election Shares held by such holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Cash Consideration; and

(iii) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-election Shares and Cash Election Shares shall be treated in the following manner:

(A) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and each holder of Non-Election Shares shall receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Cash Consideration; or

(B) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and each holder of Cash Election Shares shall receive the Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Consideration.

For purposes of this Section 1.6(e), if FNB is obligated to increase the number of Adjustable Conversion Shares to be converted into shares of FNB Stock as a result of the application of the last clause of Section 1.6(d) above, then the higher number shall be the Stock Conversion Number in the calculations set forth in this Section 1.6(e).

1.7 Closing Payment. As of the Effective Time, FNB shall deposit, or shall cause to be deposited, with Registrar and Transfer Company, transfer agent of FNB Stock (the “Exchange Agent”), for the benefit of each holder of United Stock for exchange in accordance with this Article I, (i) certificates representing the aggregate number of whole shares of FNB Stock to be issued as Stock Consideration, and (ii) an aggregate amount of cash to be delivered to holders of United Stock as Cash Consideration and in lieu of any fractional shares, to be issued and paid pursuant to this Article I for outstanding shares of United Stock (such certificates for shares of FNB Stock and such cash are referred to as the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions in accordance with this Article I, deliver the FNB Stock and cash contemplated to be issued with respect to United Stock out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by FNB, on a daily basis. Any interest and other income resulting from such investments shall be paid to FNB.

1.8 Exchange of Shares.

(a) Exchange Procedures. After the Effective Time, FNB shall cause the Exchange Agent to mail to the shareholders of United of record at the Effective Time who did not previously submit a completed Election Form transmittal materials and other appropriate written instructions (collectively, a “Transmittal Letter”) (which shall specify that delivery shall be effected, and risk of loss and title to the certificate representing shares of United Stock prior to such Effective Time shall pass, only upon proper delivery of such certificates to the Exchange Agent and which shall be in such form and have such other provisions as FNB may reasonably specify). After the Effective Time and upon the proper surrender of certificate(s) representing shares of United Stock to the Exchange Agent, together with a properly completed and duly executed Transmittal Letter or, as applicable, Election Form, the holder of such certificate(s) shall be entitled to receive in exchange therefor the number of shares of FNB Stock and the cash

to which such holder is entitled hereunder (including any cash payments to which such holder is entitled hereunder in respect of rights to receive fractional shares and any dividends or other distributions to which such holder is entitled pursuant to Section 1.8(c)), subject to any required withholding of applicable taxes. Neither FNB nor the Exchange Agent shall be obligated to deliver any of such payments in cash or stock until such holder surrenders the certificate(s) representing such holder’s shares. The certificate(s) so surrendered shall be duly endorsed as the Exchange Agent may require. If there is a transfer of ownership of any shares of United Stock not registered in the transfer records of United, the Merger Consideration shall be issued to the transferee thereof if the certificates representing such United Stock are presented to the Exchange Agent, accompanied by all documents required, in the reasonable judgment of FNB and the Exchange Agent, to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. Any portion of the Exchange Fund which remains undistributed to the holders of certificates representing United Stock for six months after the Effective Time shall be delivered to FNB, upon demand, and any shareholders of United who have not previously complied with the provisions of this Article I shall thereafter look only to FNB for payment of their claim for FNB Stock and/or cash and any dividends or distributions with respect to FNB Stock. Any portion of the Exchange Fund remaining unclaimed by holders of United Stock five years after the Effective Time (or such earlier date immediately prior to such time as such portion would otherwise escheat to or become property of any government entity) shall, to the extent permitted by applicable law, become the property of FNB free and clear of any claims or interest of any person previously entitled therein. Any other provision of this Agreement notwithstanding, neither FNB nor the Exchange Agent shall be liable to any holder of shares of United Stock for any amounts paid or properly delivered in good faith to a public official pursuant to any applicable abandoned property law.

(b) Lost Certificates. Any shareholder of United whose certificate representing shares of United Stock has been lost, destroyed, stolen or otherwise is missing shall be entitled to receive a certificate representing the shares of FNB Stock and/or any cash, including cash in lieu of fractional shares, to which he or she is entitled in accordance with and upon compliance with conditions reasonably imposed by the Exchange Agent or FNB (including, without limitation, a requirement that the shareholder provide a lost instruments indemnity bond in form, substance and amount reasonably satisfactory to the Exchange Agent and FNB).

(c) Rights of Former United Shareholders. At the Effective Time, the stock transfer books of United shall be closed as to holders of United Stock immediately prior to the Effective Time and no transfer of United Stock by any such holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of Section 1.8(a) of this Agreement, each certificate theretofore representing shares of United Stock (other than shares to be canceled pursuant to Section 1.4(a) of this Agreement and Dissenting Shares) shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration. If, after the Effective Time, certificates representing United Stock are presented to FNB or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article I. To the extent permitted by North Carolina law, former shareholders of record of United shall be entitled to vote after the Effective Time at any meeting of shareholders of FNB the number of whole shares of FNB Stock into which their respective shares of United Stock are converted, regardless of whether such holders have exchanged their

certificates representing United Stock for certificates representing FNB Stock in accordance with the provisions of this Agreement. Whenever a dividend or other distribution is declared by FNB on the FNB Stock, the record date for which is at or after the Effective Time, the declaration shall include dividends or other distributions on all shares of FNB Stock to be issued pursuant to the Merger, but beginning at the Effective Time no dividend or other distribution payable to the holders of record of FNB Stock as of any time subsequent to the Effective Time shall be delivered to the holder of any certificate representing shares of United Stock issued and outstanding at the Effective Time until such holder surrenders such certificate for exchange as provided in Section 1.8(a) of this Agreement; provided, however, that upon surrender of such United Stock certificate (or compliance with Section 1.8(b) of this Agreement), the FNB Stock certificate, together with all undelivered dividends or other distributions (without interest) and any cash payments to be paid for fractional share interests (without interest), shall be delivered and paid with respect to each share represented by such United Stock certificate.

1.9 Dissenting Shares. Notwithstanding any other provision of this Agreement to the contrary, shares of United Stock that are outstanding immediately prior to the Effective Time and that are held by shareholders who shall have not voted in favor of the Merger or consented thereto in writing and who properly shall have demanded appraisal for such shares in accordance with Article 13 of the North Carolina Business Corporation Act (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration. Such shareholders instead shall be entitled to receive payment of the appraised value of such shares held by them in accordance with the provisions of Article 13 of the North Carolina Business Corporation Act, except that all Dissenting Shares held by shareholders who shall have failed to perfect or who effectively shall have withdrawn or otherwise lost their rights to appraisal of such shares under Article 13 of the North Carolina Business Corporation Act shall thereupon be deemed to have been converted into and to have become exchangeable, as of the Effective Time, for the right to receive, without any interest thereon, the Merger Consideration upon surrender in the manner provided in Section 1.8 of the certificate or certificates that, immediately prior to the Effective Time, evidenced such shares. United shall give FNB (i) prompt notice of any written demands for appraisal of any shares of United Stock, attempted withdrawals of such demands for appraisal or any other instruments served pursuant to Article 13 of the North Carolina Business Corporation Act and received by United relating to shareholders’ rights of appraisal, and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands under Article 13 of the North Carolina Business Corporation Act consistent with the obligations of United thereunder. United shall not, except with the prior written consent of FNB, (x) make any payment with respect to such demand, (y) offer to settle or settle any demand for appraisal, or (z) waive any failure to timely deliver a written demand for appraisal or timely take any other action to perfect appraisal rights in accordance with Article 13 of the North Carolina Business Corporation Act.

1.10 Treatment of United Stock Options. At the Effective Time, each unexpired and unexercised outstanding option, whether or not then vested or exercisable in accordance with its terms, to purchase shares of United Stock (the “United Options”) previously granted by United or its subsidiaries under the United Financial, Inc. 1999 Incentive Stock Option Plan or the United Financial, Inc. 1999 Nonstatutory Stock Option Plan (collectively, the “United Option Plan”) shall be cancelled and converted into the right to receive from FNB, within 10 days following the Effective Time, cash in an amount equal to the product of (a) $14.25 minus the

exercise price per share of such United Option, times (b) the number of shares of United Stock that may be purchased upon exercise of such United Option (whether or not then exercisable). Prior to (but effective at) the Effective Time, United shall use its best efforts to (i) obtain any consents from all holders of Company Options and (ii) make any amendment to the terms of such stock option or compensation plans or arrangements that, in the case of either clause (i) or (ii), are necessary to give effect to the transactions contemplated by this Section 1.10. Immediately prior to the Effective Time, United shall terminate the United Option Plan effective as of the Effective Time.

1.11 Closing. The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Xxxxxx Xxxx Xxxxxx Xxxx & Xxxxxxxxxx P.L.L.C. in Greensboro, North Carolina, or at such other place as FNB shall designate, on a date mutually agreeable to United and FNB (the “Closing Date”) after the expiration of any and all required waiting periods following the effective date of all required approvals of the Merger by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), the North Carolina Commissioner of Banks (the “Commissioner”) and any other governmental or regulatory authorities (as soon as practicable, but in no event to be more than 60 days following the expiration of all such required waiting periods). At the Closing, FNB and United shall take such actions (including, without limitation, the delivery of certain closing documents and the execution of Articles of Merger under North Carolina law) as are required herein and as otherwise shall be required by law to consummate the Merger and cause it to become effective.

1.12 Effective Time. Subject to satisfaction or waiver of all conditions precedent set forth in this Agreement, the Merger shall become effective (the “Effective Time”) on the date and at the time on which Articles of Merger containing the Plan of Merger and the other provisions required by, and executed in accordance with applicable North Carolina and applicable federal law shall have been accepted for filing by the Secretary of State of the State of North Carolina (or such later time as may be specified in the Articles of Merger); provided, however, that unless otherwise mutually agreed upon by the parties hereto, the Effective Time shall in no event be more than ten days following the Closing Date.

1.13 Further Assurances. If at any time after the Effective Time FNB shall consider or be advised that any further deeds, assignments or assurances in law or any other actions are necessary, desirable or proper to vest, perfect or confirm of record or otherwise, in the Surviving Corporation, the title to any property or rights of United acquired or to be acquired by reason of, or as a result of, the Merger, United, its subsidiaries and their officers and directors shall execute and deliver all such proper deeds, assignments and assurances in law and do all things necessary, desirable or proper to vest, perfect or confirm title to such property or rights in FNB and otherwise to carry out the purpose of this Agreement, and the officers and directors of FNB are fully authorized and directed in the name of United or otherwise to take any and all such actions.

imperfections of title and restrictions, covenants and easements (including utility easements) which do not materially affect the value of the Real Property and which do not and will not materially detract from, interfere with or restrict the present or future use of the properties subject thereto or affected thereby. With respect to each Real Property Lease (i) such lease is valid and enforceable in accordance with its terms, (ii) there currently exists no circumstance or condition which constitutes an event of default by United or any subsidiary (as lessor or lessee) or its respective lessor or which, with the passage of time or the giving of required notices will or could constitute such an event of default, and (iii) subject to any required consent of United’s lessor, each such Real Property Lease may be assigned to FNB and the execution and delivery of this Agreement does not constitute an event of default thereunder. To the best knowledge and belief of management of United, the Real Property complies with all applicable federal, state and local laws, regulations, ordinances or orders of any governmental authority, including those relating to zoning, building and use permits, except for such noncompliance as does not or would not have a Material Adverse Effect on United and its subsidiaries, and the Real Property may be used under applicable zoning ordinances for commercial banking facilities as a matter of right rather than as a conditional or nonconforming use.

Neither United nor any subsidiary has engaged in any form of indirect lending and no such indirect loans are outstanding.

(c) To the best knowledge and belief of management of United, each loan reflected as an asset on the books of United and its subsidiaries and each guaranty therefor, is the legal, valid and binding obligation of the obligor or guarantor thereon, and no defense, offset or counterclaim has been asserted with respect to any such loan or guaranty.

(d) United has Previously Disclosed to FNB (i) a written listing of each loan, extension of credit or other asset of United or any subsidiary which, as of December 31, 2004, is classified by the FDIC, the OCC or the Commissioner as “Loss,” “Doubtful,” “Substandard” or

Except as Previously Disclosed, all securities owned by United or any subsidiary (whether owned of record or beneficially) are held free and clear of all mortgages, liens, pledges, encumbrances or any other restriction or rights of any other person or entity, whether contractual or statutory, which would materially impair the ability of United or any subsidiary to dispose freely of any such security or otherwise to realize the benefits of ownership thereof at any time. There are no voting trusts or other agreements or undertakings to which United or any subsidiary is a party with respect to the voting of any such securities. With respect to all “repurchase agreements” to which United or any subsidiary has “purchased” securities under agreement to resell, United or such subsidiary has a valid, perfected first lien or security interest in the government securities or other collateral securing the repurchase agreement, and the value of the collateral securing each such repurchase agreement equals or exceeds the amount of the debt owed that is secured by such collateral.

Without limiting the generality of the foregoing, all reports and returns with respect to the Retirement Plans required to be filed with any governmental department, agency, service or other authority have been properly and timely filed. There are no disputes or unresolved disagreements with respect to the Retirement Plans or the administration thereof currently existing between United, any subsidiary or any trustee or other fiduciary thereunder, and any governmental agency, any current or former employee of United, any subsidiary or beneficiary of any such employee or any other person or entity. No “reportable event” within the meaning of Section 4043(b) of ERISA has occurred at any time with respect to the Retirement Plans, other than those, when taken as a whole, that would not have a Material Adverse Effect on United or its subsidiaries.

(d) No liability under subtitle C or D of Title IV of ERISA has been or is expected to be incurred by United or any subsidiary with respect to the Retirement Plans or with respect to any other ongoing, frozen or terminated defined benefit pension plan currently or formerly maintained by United or any subsidiary. Neither United nor any subsidiary presently contributes to a “Multiemployer Plan” or has ever contributed to such a plan. All contributions required to be made pursuant to the terms of each of the Plans (including without limitation the Retirement Plans and any other “pension plan” (as defined in Section 3(2) of ERISA, provided such plan is intended to qualify under the provisions of Section 401(a) of the Code) maintained by United or any subsidiary have been timely made. Neither the Retirement Plans nor any other “pension plan” maintained by United or any subsidiary have an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA. Neither United nor any subsidiary has provided, and is not required to provide, security to any “pension plan” or to any “Single Employer Plan” pursuant to Section 401(a)(29) of the Code. Under the Retirement Plans and any other “pension plan” maintained by United or any subsidiary as of the last day of the most recent plan year ended prior to the date hereof, the actuarially determined present value of all “benefit liabilities,” within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in the plan’s most recent actuarial valuation) did not exceed the then current value of the assets of such plan, and there has been no material change in the financial condition of any such plan since the last day of the most recent plan year.

(e) There are no restrictions on the rights of United or any subsidiary to amend or terminate any Plan. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (except as otherwise specifically provided for or contemplated by the transactions described in this Agreement) (i) result in any

payment to any person (including, without limitation, any severance compensation or payment, unemployment compensation, “golden parachute” or “change in control” payment, or otherwise) becoming due under any plan or agreement to any director, officer, employee or consultant, (ii) increase any benefits otherwise payable under any plan or agreement, or (iii) result in any acceleration of the time of payment or vesting of any such benefit.

2.24 Insurance. United has in effect a “financial institutions bond” and such other policies of general liability, casualty, directors and officers liability, employee fidelity, errors and omissions and other property and liability insurance as have been Previously Disclosed to FNB (the “Policies”). The Policies provide coverage in such amounts and against such liabilities, casualties, losses or risks as is required by applicable law or regulation; and, in the judgment of management of United, the insurance coverage provided under the Policies is reasonable and adequate in all respects for United and its subsidiaries. Each of the Policies is in full force and effect and is valid and enforceable in accordance with its terms, and is underwritten by an insurer of recognized financial responsibility that is qualified to transact business in North Carolina; and United and its subsidiaries have taken all requisite actions (including the giving of required notices) under each such Policy to preserve all rights thereunder with respect to all matters. Neither United nor any subsidiary is in default under the provisions of, has received notice of cancellation or nonrenewal of or any premium increase on, or has any knowledge of any failure to pay any premium on or any inaccuracy in any application for any Policy. There are no pending claims under any Policy, and United has no knowledge of any facts or of the occurrence of any event that is reasonably likely to result in any such claim.

2.25 Insurance of Deposits. Alamance Bank is an “insured institution” as defined in the Federal Deposit Insurance Act and applicable regulations thereunder. The deposits of each depositor in Alamance Bank are insured by the FDIC to the maximum amount provided by law, all deposit insurance premiums due from Alamance Bank to the FDIC have been paid in full in a timely fashion, and, to the best knowledge and belief of United, no proceedings have been commenced or are contemplated by the FDIC or otherwise to terminate such insurance.

United has Previously Disclosed (i) the name and current salary or wage rate for each present employee of United or its subsidiaries, (ii) the name of and number of shares of United Stock beneficially owned by each of the directors and officers of United and by any person or entity known to United to own beneficially 5% or more of United Stock, and (iii) the name, number and vesting schedule of outstanding options and restricted stock awards held by each person to whom a stock option or restricted stock award has been granted and currently is outstanding under any stock option or other plan of United, including, without limitation, the United Option Plan.

2.27 Affiliates. United will deliver to FNB within 15 days of the date hereof a listing of those persons deemed by United and its counsel as of the date of this Agreement to be “Affiliates” of United as that term is defined in Rule 405 promulgated under the 1933 Act, including persons, trusts, estates or other entities related to persons deemed to be Affiliates of United.

2.28 State Takeover Laws. United has taken all necessary action to exempt the transactions contemplated by this Agreement from any applicable “moratorium,” “control share,” “fair price,” “business combination,” or other anti-takeover laws and regulations of the State of North Carolina (collectively, “Takeover Laws”).

2.29 Obstacles to Regulatory Approval or Tax Treatment. To the best knowledge and belief of management of United, there exists no fact or condition relating to United or any subsidiary that may reasonably be expected to (i) prevent, impede or delay FNB or United from obtaining the regulatory approvals required to consummate transactions described herein, or (ii) prevent the Merger from qualifying to be a tax-free reorganization under Section 368(a)(1)(A) of the Code; and, if any such fact or condition becomes known to United, United shall promptly (and in any event within three days after obtaining such knowledge) communicate such fact or condition to the President of FNB.

FNB shall attempt in good faith to complete all such Phase I environmental assessments within 60 days following the date of this Agreement and thereafter to conduct and complete any such additional studies, testing, sampling and analyses as promptly as practicable. Subject to the provisions of Section 8.3(c) below, the costs of the Environmental Survey shall be paid by FNB.

possession relating thereto) and, at FNB’s sole option and discretion, at any time thereafter and up to the Effective Time, it may terminate this Agreement without further obligation or liability to United or its shareholders.

6.8 Tax-Free Reorganization. FNB and United shall each use its best efforts to cause the Merger to qualify as a tax-free “reorganization” within the meaning of Section 368(a)(1)(A) of the Code and shall not intentionally take any action that would cause the Merger to fail to so qualify.

6.9 Certain Modifications.

6.10 Transition Team. FNB and United shall create a transition team comprised of staff and representatives of United and staff and representatives of FNB (the “Transition Team”).

FNB shall indemnify, hold harmless and defend United from and against any and all claims, disputes, demands, causes of action, suits, proceedings, losses, damages, liabilities, obligations, costs and expenses of every kind and nature that arise from or are related to claims by third parties, including without limitation reasonable attorneys’ fees and legal costs and expenses in connection therewith, whether known or unknown, and whether now existing or hereafter arising, which may be threatened against, incurred, undertaken, received or paid by United:

(i) in connection with or which arise out of or result from or are based upon (A) FNB’s operations or business transactions or its relationship with any of its employees, or (B) FNB’s failure to comply with any statute or regulation of any federal, state or local government or agency (or any political subdivision thereof) in connection with the transactions described in this Agreement;

(ii) in connection with or which arise out of or result from or are based upon any fact, condition or circumstance that constitutes a breach by FNB of, or any inaccuracy, incompleteness or inadequacy in, any of its representations or warranties under or in connection with this Agreement, or any failure of FNB to perform any of its covenants, agreements or obligations under or in connection with this Agreement; and,

(iii) in connection with or which arise out of or result from or are based upon any information provided by FNB which is included in the Proxy Statement/Prospectus and which information causes the Proxy Statement/Prospectus at the time of its mailing to FNB’s and United’s shareholders to contain any untrue statement of a material fact or to omit any material fact required to be stated therein or necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not false or misleading.

9.2 Procedure for Claiming Indemnification.

(a) By FNB. If any matter subject to indemnification hereunder arises in the form of a claim against FNB or its successors and assigns (herein referred to as a “Third Party Claim”), FNB promptly shall give notice and details thereof, including copies of all pleadings and pertinent documents, to United. Within 15 days of such notice, United either (i) shall pay the Third Party Claim either in full or upon agreed compromise or (ii) shall notify FNB that United disputes the Third Party Claim and intends to defend against it, and thereafter shall so defend and pay any adverse final judgment or award in regard thereto. Such defense shall be controlled by United and the cost of such defense shall be borne by United except that FNB shall

have the right to participate in such defense at its own expense and provided that United shall have no right in connection with any such defense or the resolution of any such Third Party Claim to impose any cost, restriction, limitation or condition of any kind upon FNB or its successors or assigns. FNB agrees that it shall cooperate in all reasonable respects in the defense of any such Third Party Claim, including making personnel, books and records relevant to the Third Party Claim available to United without charge therefor except for out-of-pocket expenses. If United fails to take action within 15 days as hereinabove provided or, having taken such action, thereafter fails diligently to defend and resolve the Third Party Claim, FNB shall have the right to pay, compromise or defend the Third Party Claim and to assert the indemnification provisions hereof. FNB also shall have the right, exercisable in good faith, to take such action as may be necessary to avoid a default prior to the assumption of the defense of the Third Party Claim by United.

(b) By United. If any matter subject to indemnification hereunder arises in the form of a claim against United or its successors and assigns (herein referred to as a “Third Party Claim”), United promptly shall give notice and details thereof, including copies of all pleadings and pertinent documents, to FNB. Within 15 days of such notice, FNB either (i) shall pay the Third Party Claim either in full or upon agreed compromise or (ii) shall notify United that FNB disputes the Third Party Claim and intends to defend against it, and thereafter shall so defend and pay any adverse final judgment or award in regard thereto. Such defense shall be controlled by FNB and the cost of such defense shall be borne by FNB except that United shall have the right to participate in such defense at its own expense and provided that FNB shall have no right in connection with any such defense or the resolution of any such Third Party Claim to impose any cost, restriction, limitation or condition of any kind upon United or its successors and assigns. United agrees that it shall cooperate in all reasonable respects in the defense of any such Third Party Claim, including making personnel, books and records relevant to the Third Party Claim available to FNB without charge therefor except for out-of-pocket expenses. If FNB fails to take action within 15 days as hereinabove provided or, having taken such action, thereafter fails diligently to defend and resolve the Third Party Claim, United shall have the right to pay, compromise or defend the Third Party Claim and to assert the indemnification provisions hereof. United also shall have the right, exercisable in good faith, to take such action as may be necessary to avoid a default prior to the assumption of the defense of the Third Party Claim by FNB.

ARTICLE X. MISCELLANEOUS PROVISIONS

10.1 Reservation of Right to Revise Structure. Notwithstanding any provision herein to the contrary, FNB shall have the unilateral right to revise the structure of the Merger to achieve the tax consequences described in Section 6.8 or for any other reason FNB may deem advisable; provided, however, that no such change will (i) alter or change the amount or kind of consideration to be received by the shareholders of United in the Merger or (ii) adversely affect the tax treatment to the shareholders of United as a result of receiving such consideration. In the event of such election by FNB, the parties hereto shall execute an appropriate amendment to this Agreement.

10.2 Survival of Representations, Warranties, Indemnification and Other Agreements.

(a) Representations, Warranties and Other Agreements. None of the representations, warranties or agreements herein shall survive the effectiveness of the Merger, and no party shall have any right after the Effective Time to recover damages or any other relief from any other party to this Agreement by reason of any breach of representation or warranty, any nonfulfillment or nonperformance of any agreement contained herein, or otherwise; provided, however, that the parties’ agreements contained in Section 6.6 above and FNB’s covenants contained in Sections 5.1 through 5.5 above shall survive the effectiveness of the Merger.

(b) Indemnification. The parties’ indemnification agreements and obligations pursuant to Section 9.1 above shall become effective only in the event this Agreement is terminated, and neither of the parties shall have any obligations under Section 9.1 in the event of or following consummation of the Merger.

10.3 Waiver. Any term or condition of this Agreement may be waived (except as to matters of regulatory approvals and approvals required by law), either in whole or in part, at any time by the party which is, and whose shareholders are, entitled to the benefits thereof, provided, however, that any such waiver shall be effective only upon a determination by the waiving party (through action of its Board of Directors) that such waiver would not adversely affect the interests of the waiving party or its shareholders; and, provided further, that no waiver of any term or condition of this Agreement by any party shall be effective unless such waiver is in writing and signed by the waiving party or as provided in Sections 8.2(a) and 8.2(b) above, or be construed to be a waiver of any succeeding breach of the same term or condition. No failure or delay of any party to exercise any power, or to insist upon a strict compliance by any other party of any obligation, and no custom or practice at variance with any terms hereof, shall constitute a waiver of the right of any party to demand full and complete compliance with such terms.

10.4 Amendment. This Agreement may be amended, modified or supplemented at any time or from time to time prior to the Effective Time, and either before or after its approval by the shareholders of United and FNB, by an agreement in writing approved by a majority of the Boards of Directors of FNB and United executed in the same manner as this Agreement; provided however, that the provisions of this Agreement relating to the manner or basis in which shares of United Stock are converted into FNB Stock shall not be amended after the approval of this Agreement and Plan of Merger by the shareholders of United without the requisite approval of such shareholders of such amendment.

AGREEMENT AND PLAN OF MERGER


SCHEDULE		DESCRIPTION

A		Plan of Merger

SCHEDULE A

to Agreement and Plan of Merger

dated as of May 9, 2005

PLAN OF MERGER

UNITED FINANCIAL, INC.

WITH AND INTO

FNB CORP.

A. Parties to Merger. The parties to the proposed merger are United Financial, Inc., a North Carolina corporation (“United”), and FNB Corp., a North Carolina corporation (“FNB”).

B. Nature of Transaction. Subject to the provisions of this Plan of Merger, United shall be merged with and into FNB (the “Merger”) with the effect provided in the North Carolina Business Corporation Act.

C. Surviving Corporation. FNB shall be the surviving corporation in the Merger. At the Effective Time (as hereinafter defined) of the Merger, the name of the surviving corporation shall not be changed.

D. Effective Time. The Merger shall be effective on the date and at the time on which Articles of Merger containing this Plan of Merger and the other provisions required by, and executed in accordance with, applicable North Carolina and applicable federal law shall have been accepted for filing by the Secretary of State of the State of North Carolina (or such later time as may be specified in the Articles of Merger) (the “Effective Time”). At the Effective Time, the separate corporate existence of United shall cease and the corporate existence of FNB shall continue with all of its purposes, objects, rights, privileges, powers and franchises, all of which shall be unaffected and unimpaired by the Merger.

E. Conversion and Exchange of Shares.

1. At the Effective Time, all rights of United’s shareholders with respect to all then outstanding shares of the common stock of United, $1.00 par value (“United Stock”) shall cease to exist, and the holders of United Stock shall cease to be, and shall have no further rights as, shareholders of United. Subject to Section E.7 below, at the Effective Time, each such outstanding share of United Stock (except for shares held, other than in a fiduciary capacity or as a result of debts previously contracted, by United, FNB or any of their subsidiaries, which shall be canceled in the Merger, and for Dissenting Shares (as defined in Section E.7)) shall be converted exclusively into the right to receive, at the election of the holder thereof, either: (A) $14.25 in cash, without interest; (B) 0.6828 shares (the “Exchange Ratio”) of the common stock of FNB, par value $2.50 (the “FNB Stock”); or (C) 35% of the cash amount set forth in clause (A) above and a number of shares of FNB equal to 65% of the Exchange Ratio; provided, however, that a holder of United Stock may, pursuant to Section E.4, make no election, in

which case such shares of United Stock held by such holder shall be converted exclusively into the right to receive the consideration set forth in Section E.4(e) below with respect to Non-Election Shares (as defined in Section E.4(b)). The amount of cash into which shares of United Stock shall be converted pursuant to this Plan of Merger is sometimes hereinafter referred to as “Cash Consideration,” and the number of shares of FNB Stock into which shares of United Stock shall be converted pursuant to this Plan of Merger is sometimes hereinafter referred to as “Stock Consideration.” The Cash Consideration and Stock Consideration are sometimes referred to herein collectively as the “Merger Consideration.” No share of United Stock, other than Dissenting Shares (defined in Section E.7), shall be deemed to be outstanding or have any rights other than those set forth in this Section E.1 after the Effective Time. [The Exchange Ratio is subject to possible adjustment in accordance with Section 1.5(c) of the Agreement and Plan of Merger, dated as of May 9, 2005, by and between FNB and United. If so adjusted, the adjusted Exchange Ratio shall be reflected in this Plan of Merger prior to filing with the Secretary of State of North Carolina.]

2. Each share of the FNB Stock issued and outstanding immediately prior to the Effective Time of the Merger shall continue to be issued and outstanding and shall not be affected by the Merger.

3. Notwithstanding any other provision of this Plan of Merger, each holder of shares of United Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of FNB Stock (after taking into account all certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of FNB Stock multiplied by the market value of one share of FNB Stock upon the Effective Time. The market value of one share of FNB Stock at the Effective Time shall be the last sale price of FNB Stock on Nasdaq Stock Market, Inc. National Market System as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source selected by FNB, on the last trading day preceding the Effective Time. No such holder will be entitled to dividends, voting rights, or any other rights as a shareholder in respect of any fractional shares.

4. (a) An election form (an “Election Form”) and other appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing United Stock shall pass, only upon proper delivery of such certificates to the exchange agent in such form as United and FNB shall mutually agree shall be mailed on the Mailing Date (as defined below) to each shareholder of record of United. The “Mailing Date” shall be the date on which proxy materials relating to the Merger are mailed to holders of shares of United Stock.

(b) Each Election Form shall entitle the holder of shares of United Stock (or the beneficial owner through appropriate and customary documentation and instructions) to (i) elect to receive the Cash Consideration for all of such holder’s shares (a “Cash Election”), (ii) elect to receive the Stock Consideration for all of such holder’s

shares (a “Stock Election”), (iii) elect to receive Merger Consideration in accordance with clause (C) of the first sentence of Section E.1 (a “Mixed Election”), or (iv) make no election or to indicate that such holder has no preference as to the receipt of the Cash Consideration or the Stock Consideration (a “Non-Election”). Shareholders of record of United who hold shares of United Stock as nominees, trustees or in other representative capacities may submit multiple Election Forms, provided that such representative certifies that each such Election Form covers all the shares of United Stock held by that representative for a particular beneficial owner. Shares of United Stock in respect of which a Cash Election shall have been made are referred to herein as “Cash Election Shares.” Shares of United Stock in respect of which a Stock Election shall have been made are referred to herein as “Stock Election Shares.” Shares of United Stock in respect of which no election shall have been made are referred to as “Non-Election Shares.” The aggregate number of shares of United Stock with respect to which a Stock Election shall have been made is referred to herein as the “Stock Election Number.” Shares of United Stock with respect to which a Mixed Election shall have been made shall not be deemed either Stock Election Shares or Cash Election Shares, but shall in all events be converted into the right to receive the Merger Consideration as specified in subsection (e) of this Section E.4.

(c) To be effective, a properly completed Election Form shall be submitted to the exchange agent on or before 5:00 p.m. North Carolina time on the last business day prior to the date on which the shareholders of United meet to vote upon this Plan of Merger (or such other time and date as United and FNB may mutually agree) (the “Election Deadline”). An election shall have been properly made only if the exchange agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by one or more certificates (or customary affidavits and, if required by FNB pursuant to Section E.8, indemnification regarding the loss or destruction of such certificates or the guaranteed delivery of such certificates) representing all shares of United Stock covered by such Election Form, together with duly executed transmittal materials included with the Election Form. Any United shareholder may at any time prior to the Election Deadline change his or her election by written notice received by the exchange agent prior to the Election Deadline accompanied by a properly completed and signed revised Election Form. Any United shareholder may, at any time prior to the Election Deadline, revoke his or her election by written notice received by the exchange agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her certificates, or of the guarantee of delivery of such certificates, previously deposited with the exchange agent. All elections shall be revoked automatically if the exchange agent is notified in writing by FNB and United that the Agreement and Plan of Merger, dated as of May 9, 2005, by and between FNB and United (the “Merger Agreement”) has been terminated. If a United shareholder either (i) does not submit a properly completed Election Form by the Election Deadline, or (ii) revokes its Election Form prior to the Election Deadline, the shares of United Stock held by such shareholder shall be designated Non-Election Shares. FNB shall cause the certificates representing United Stock described in clause (ii) above to be promptly returned without charge to the person submitting the Election Form upon written request to that effect from the person who

submitted the Election Form. Subject to the terms of this Plan and of the Election Form, the exchange agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in any Election Form, and any good faith decisions of the exchange agent regarding such matters shall be binding and conclusive.

(d) Notwithstanding any other provision contained in this Plan, 65% (the “Stock Conversion Number”) of the total number of shares of United Stock outstanding at the Effective Time to be converted into Merger Consideration pursuant to Section E.1(a) excluding such shares as may be subject to an effective Mixed Election (the “Adjustable Conversion Shares”), shall be converted into the Stock Consideration and the remaining Adjustable Conversion Shares shall be converted into the Cash Consideration (in each case, excluding shares of United Stock to be canceled as provided in Section E.1 and Dissenting Shares); provided, however, that for federal income tax purposes, it is intended that the Merger will qualify as a reorganization under the provisions of Section 368(a) of the Code and, notwithstanding anything to the contrary contained herein, in order that the Merger will not fail to satisfy continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, as reasonably determined by counsel to FNB, FNB shall increase the number of Adjustable Conversion Shares that will be converted into the Stock Consideration and reduce the number of Adjustable Conversion Shares that will be converted into the right to receive the Cash Consideration.

(e) Within five business days after the later to occur of the Election Deadline or the Effective Time, FNB shall cause the exchange agent to effect the allocation among holders of United Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) In any event, all shares of United Stock with respect to which a Mixed Election shall have been made shall be converted into 35% of the amount of cash set forth in clause (A) of the first sentence of Section 1.5(a) and 65% of the Exchange Ratio;

(ii) If the Stock Election Number exceeds the Stock Conversion Number, then all Cash Election Shares and all Non-Election Shares shall be converted into the right to receive the Cash Consideration, and each holder of Stock Election Shares will be entitled to receive the Stock Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (x) the number of Stock Election Shares held by such holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Cash Consideration; and

(iii) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-election Shares and Cash Election Shares shall be treated in the following manner:

(A) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and each holder of Non-Election Shares shall receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Cash Consideration; or

(B) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and each holder of Cash Election Shares shall receive the Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Consideration.

For purposes of this Section E.4(e), if FNB is obligated to increase the number of Adjustable Conversion Shares to be converted into shares of FNB Stock as a result of the application of the last clause of Section E.4(d) above, then the higher number shall be the Stock Conversion Number in the calculations set forth in this Section E.4(e).

5. Each holder of a certificate representing shares of United Stock to be converted or exchanged in the Merger shall surrender such certificate for cancellation, and after the Effective Time and after such surrender, shall be entitled to receive in exchange therefor the consideration to which it is entitled under this Plan. Until so surrendered, each outstanding certificate that prior to the Effective Time represented shares of United Stock shall be deemed for all purposes to evidence ownership of the consideration to be issued and paid for the conversion or exchange of such shares under this Plan.

6. From and after the Effective Time of the Merger, there shall be no further transfers on the stock transfer books of United of the shares of United Stock that were outstanding immediately prior to the Effective Time of the Merger. If after such Effective Time, certificates representing shares of United Stock are presented to United, FNB or the exchange agent for any reason, they shall be canceled and exchanged as provided for herein.

7. Notwithstanding any other provision of this Plan to the contrary, shares of United Stock that are outstanding immediately prior to the Effective Time and that are held by shareholders who shall have not voted in favor of the Merger or consented thereto in writing and who properly shall have demanded appraisal for such shares in accordance with Article 13 of the North Carolina Business Corporation Act (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration. Such shareholders instead shall be entitled to receive payment of the appraised value of such shares held by them in accordance with the provisions of Article 13 of the North Carolina Business Corporation Act, except that all Dissenting Shares held by shareholders who shall have failed to perfect or who effectively shall have withdrawn or otherwise lost their rights to appraisal of such shares under Article 13 of the North Carolina Business Corporation Act shall thereupon be deemed to have been converted into and to have become exchangeable, as of the Effective Time, for the right to receive, without any interest thereon, the Merger Consideration upon surrender in the manner provided in Section 1.8 of the certificate or certificates that, immediately prior to the Effective Time, evidenced such shares. United shall give FNB (i) prompt notice of any written demands for appraisal of any shares of United Stock, attempted withdrawals of such demands for appraisal or any other instruments served pursuant to Article 13 of the North Carolina Business Corporation Act and received by United relating to shareholders’ rights of appraisal, and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands under Article 13 of the North Carolina Business Corporation Act consistent with the obligations of United thereunder. United shall not, except with the prior written consent of FNB, (x) make any payment with respect to such demand, (y) offer to settle or settle any demand for appraisal, or (z) waive any failure to timely deliver a written demand for appraisal or timely take any other action to perfect appraisal rights in accordance with Article 13 of the North Carolina Business Corporation Act.

8. Any shareholder of United whose certificate representing shares of United Stock has been lost, destroyed, stolen or otherwise is missing shall be entitled to receive a certificate representing the shares of FNB Stock and/or any cash, including cash in lieu of fractional shares, to which he or she is entitled in accordance with and upon compliance with conditions reasonably imposed by the exchange agent or FNB (including, without limitation, a requirement that the shareholder provide a lost instruments indemnity bond in form, substance and amount reasonably satisfactory to the exchange agent and FNB).

F. Abandonment. This Plan of Merger may be terminated and the Merger may be abandoned at any time prior to the Effective Time upon termination of the Merger Agreement.
