(b) At the Effective Time, Premier shall merge with and into Merger Sub (the “Merger”), the separate corporate existence of Premier shall cease and Merger Sub shall survive and continue to exist as a Virginia corporation (Merger Sub, as the surviving corporation in the Merger, sometimes being referred to herein as the “Surviving Corporation”). United may at any time prior to the Effective Time change the method of effecting the combination with Premier (including, without limitation, the provisions of this Article II) if and to the extent it deems such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) cause the approval of the stockholders of United to be required as a condition to the Merger, (ii) alter or change the amount or kind of Merger Consideration (as hereinafter defined), or the relative proportions of cash and United Common Stock included therein, (iii) adversely affect the tax treatment of Premier’s stockholders as a result of receiving the Merger Consideration or (iv) materially impede or delay consummation of the transactions contemplated by this Agreement; and provided further, that United shall provide Premier prior written notice of such change and the reasons therefore.

(c) Subject to the satisfaction or waiver of the conditions set forth in Article VIII, the Merger shall become effective upon the occurrence of the filing in the office of the Corporation Commission articles of merger in accordance with Section 13.1-720 of the VSCA or such later date and time as may be set forth in such certificate of merger. The Merger shall have the effects prescribed in the VSCA.

The time on the Effective Date when the Merger shall become effective is referred to as the “Effective Time.”

(b) Notwithstanding any other provision in this Agreement to the contrary, if United shall exercise its right to delay the Effective Date pursuant to this Section, and a record date for any dividend or other distribution in respect of the United Common Stock is taken during the period of such delay such that the Premier stockholders will not be entitled to participate in such dividend, each stockholder of Premier shall be entitled to receive, upon surrender of the Old Certificates and compliance with the other provisions of Article IV, a payment equal to the amount and kind of dividend or other distribution that such holder would have received had such holder been a holder of record of the shares of United Common Stock issuable to such holder in the Merger on the record date for such dividend or other distribution.

ARTICLE III

The Bank Merger

3.01 The Bank Merger. (a) Immediately after the Effective Time, Marathon Bank, Rockingham Heritage Bank and Premier Bank, wholly-owned subsidiaries of Premier, shall merge with and into United Bank, a wholly-owned subsidiary of United (the “Bank Merger”), the separate existence of Marathon Bank, Rockingham Heritage Bank and Premier Bank shall cease and United Bank shall survive and continue to exist as a Virginia banking corporation. United may at any time prior to the Effective Time, change the method of effecting the combination with Marathon Bank, Rockingham Heritage Bank and Premier Bank (including without limitation the provisions of this Article III) if and to the extent it deems such changes necessary, appropriate or desirable; provided, however that no such change shall (i) alter or change the amount or kind of Merger Consideration, or the relative proportions of cash and United Common Stock included therein, (ii) adversely affect the tax treatment of Premier’s stockholders as a result of receiving the Merger Consideration or (iii) materially impede or delay consummation of the transactions contemplated by this Agreement, and provided further, that United shall provide Premier with prior written notice of such change and the reasons therefore.

(b) Subject to the satisfaction or waiver of the conditions set forth in Article VIII, the Bank Merger shall become effective upon the occurrence of the filing in the office in the Corporation Commission of articles of merger in accordance with Section 13.1-720 of the VSCA or such later date and time as may be set forth in such articles and the issuance of a certificate of merger by the Corporation Commission under the VSCA. The Bank Merger shall have the effects prescribed in the VSCA.

4.01 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person:

(a) Stock Consideration and Cash Consideration. Each holder of a share of Premier Common Stock (other than Premier or its subsidiaries or United and its subsidiaries and Dissenters’ Shares, except for shares held by them in a fiduciary capacity) shall receive in respect thereof, at the election of the holder as provided in and subject to the limitations set forth in this Agreement, either (i) 0.93 shares (“Exchange Ratio”) of United Stock (the “Stock Consideration”) or (ii) $34.00 in cash without interest (the “Cash Consideration”) or a combination of the Stock Consideration and the Cash Consideration. The Cash Consideration and the Stock Consideration are sometimes referred to herein collectively as the “Merger Consideration.”

(b) Outstanding United Stock. Each share of United Common Stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and unaffected by the Merger.

(c) Treasury Shares. Each share of Premier Common Stock held as Treasury Stock immediately prior to the Effective Time shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefore.

(d) Merger Sub. Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall remain outstanding and unaffected by the Merger, and no consideration shall be issued in exchange therefor.

4.02 Election and Proration Procedures.

(a) An election form in such form as Premier and United shall mutually agree (an “Election Form”) shall be mailed on the Mailing Date (as defined below) to each holder of record of shares of Premier Common Stock as of a record date that shall be the same date as the record date for eligibility to vote on the Merger. The “Mailing Date” shall be the date on which proxy materials relating to the Merger are mailed to holders of shares of Premier Common Stock. United shall make available Election Forms as may be reasonably requested by all persons who become holders of Premier Common Stock after the record date for eligibility to vote on the Merger and prior to the Election Deadline (as defined herein), and Premier shall provide to the Exchange Agent all information reasonably necessary for it to perform its obligations as specified herein.

(b) Each Election Form shall entitle the holder of shares of Premier Common Stock (or the beneficial owner through appropriate and customary documentation and instructions) to (i) elect to receive the Stock Consideration for all of such holder’s shares (a “Stock Election”), (ii) elect to receive the Cash Consideration for all of such holder’s shares (a “Cash Election”), (iii) elect to receive the Stock Consideration with respect to some of such holder’s shares and the Cash Consideration with respect to such holder’s remaining shares (a “Mixed Election”) or (iv) make no election or indicate that such holder has no preference as to the receipt of the Cash Consideration or the Stock Consideration (a “Non-Election”). Holders of record of shares of Premier Common Stock who hold such shares as nominees, trustees or in other representative capacities (a “Representative”) may submit multiple Election Forms, provided that such Representative certifies that each such Election Form covers all the shares of Premier Common Stock held by that Representative for a particular beneficial owner. Shares of Premier Common Stock as to which a Cash Election has been made (including pursuant to a

Mixed Election) are referred to herein as “Cash Election Shares.” Shares of Premier Common Stock as to which a Stock Election has been made (including pursuant to a Mixed Election) are referred to herein as “Stock Election Shares.” Shares of Premier Common Stock as to which no election has been made are referred to as “Non-Election Shares.” For purposes of this Section, Dissenters’ Shares shall be deemed Cash Election Shares. The aggregate number of shares of Premier Common Stock with respect to which a Stock Election has been made is referred to herein as the “Stock Election Number.”

(c) To be effective, a properly completed Election Form must be received by a bank or trust company designated by United and reasonably satisfactory to Premier (the “Exchange Agent”) on or before 5:00 p.m., New York City time, on the third business day immediately preceding the Premier Meeting (or such other time and date as Premier and United 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 Old Certificates (or customary affidavits and, if required by United, indemnification regarding the loss or destruction of such Old Certificates or the guaranteed delivery of such Old Certificates) representing all shares of Premier Common Stock covered by such Election Form, together with duly executed transmittal materials included with the Election Form. Any Premier stockholder 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 Premier stockholder 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 Old Certificates, or of the guarantee of delivery of such Old Certificates, previously deposited with the Exchange Agent. Notwithstanding the previous two sentences, if the Effective Time shall not occur within 15 days following the Election Deadline, then during the period commencing on the 16th day following the Election Deadline and ending on 5:00 p.m., New York City time, on the third business day prior to the Closing Date (the “Election Modification Period”), any Premier stockholder may change or revoke his or her election in the manner specified in the previous two sentences. All elections shall be revoked automatically if the Exchange Agent is notified in writing by United and Premier that this Agreement has been terminated. If a stockholder either (i) does not submit a properly completed Election Form by the Election Deadline, (ii) revokes (as opposed to changes) his or her Election Form prior to the Election Deadline and does not submit a new properly executed Election Form prior to the Election Deadline or (iii) revokes his or her Election Form during the Election Modification Period, the shares of Premier Common Stock held by such stockholder shall be designated Non-Election Shares. United shall cause the Certificates representing Premier Common Stock described in (ii) or (iii) in the immediately preceding sentence 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, at least 50% and no more than 65% of the total number of shares of Premier Common Stock outstanding at the Effective Time (the “Minimum Stock Conversion Number” and the “Maximum Stock Conversion Number” respectively) shall be converted into the Stock Consideration and the remaining outstanding shares of Premier Common Stock (excluding shares of Premier Common Stock to be canceled as provided in Section 4.01(c)) shall be converted into the Cash Consideration.

(e) Within three business days after the Election Deadline, United shall cause the Exchange Agent to effect the allocation among holders of Premier Common Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) If the Stock Election Number exceeds the Maximum 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 (A) the number of shares of United Common Stock equal to the product obtained by multiplying (1) the number of Stock Election Shares held by such holder by (2) the Exchange Ratio by (3) a fraction the numerator of which is the Maximum Stock Conversion Number and the denominator of which is the Stock Election Number (the “Stock Proration Factor”) and (B) cash in an amount equal to the product obtained by multiplying (1) the number of Stock Election Shares held by such holder by (2) the Cash Consideration by (3) one minus the Stock Proration Factor;

(ii) If the Stock Election Number is less than the Minimum Stock Conversion Number (the amount by which the Minimum 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 (1) the number of shares of United Common Stock equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) the Exchange Ratio by (z) a fraction the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares (the “Non-Election Proration Factor”) and (B) cash in an amount equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) the Cash Consideration by (z) one minus the Non-Election Proration Factor; 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 (1) the number of shares of United Stock equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) the Exchange Ratio by (z) a fraction the numerator of which is the amount by which the Shortfall Number exceeds the number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares (the “Cash Proration Factor”) and (B) cash in an amount equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) the Cash Consideration by (z) one minus the Cash Proration Factor.

(C) The purchase of fractional shares pursuant to Section 4.04 of this Agreement shall be taken into account in calculating the number of Non-Election Shares and Cash Election Shares to convert into the right to receive Stock Consideration under this Section 4.02(e)(ii) to ensure that the Minimum Stock Conversion Number is at least 50%.

4.03 Rights as Stockholders; Stock Transfers. At the Effective Time, holders of Premier Common Stock shall cease to be, and shall have no rights as, stockholders of Premier, other than to receive the Merger Consideration and any dividend or other distribution with respect to such Premier Common Stock with a record date occurring prior to the Effective Time, the payment, if any, in lieu of certain dividends on United Common Stock provided for in Section 2.02(b), and the consideration provided under this Article IV. After the Effective Time, there shall be no transfers on the stock transfer books of Premier or the Surviving Corporation of shares of Premier Common Stock.

4.04 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of United Common Stock and no certificates or scrip therefore, or other evidence of ownership thereof, will be issued in the Merger; instead, United shall pay to each holder of Premier Common Stock who would otherwise be entitled to a fractional share of United Common Stock (after taking into account all Old Certificates registered in the name of such holder) an amount in cash (without interest) determined by multiplying such fraction by the closing price of United Common Stock as reported by NASDAQ reporting system (as reported in the Wall Street Journal) on the Effective Date.

4.05 Exchange Procedures.

(a) At or prior to the Effective Time, United shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of certificates formerly representing shares of Premier Common Stock (“Old Certificates”), for exchange in accordance with this Article IV, (i) certificates representing shares of United Common Stock (“New Certificates”) and (ii) an amount of cash necessary to pay the cash portion of the Merger Consideration and any payments required by Section 2.02(b) (the “Exchange Fund”). The Exchange Fund will be distributed in accordance with the Exchange Agent’s normal and customary procedures established in connection with merger transactions.

(b) As soon as practicable after the Effective Time, and in no event later than five business days thereafter, the Exchange Agent shall mail to each holder of record of one or more Old Certificates who has not previously submitted such Old Certificates with a properly completed Election Form a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates, if any, that the holders of the Old Certificates are entitled to receive pursuant to Article IV, and the cash, if any, that the holders of the Old Certificates are entitled to receive pursuant to Article IV, any cash in lieu of fractional shares into which the shares of Premier Common Stock represented by the Old Certificates shall have been converted pursuant to this Agreement and any payment required pursuant to Section 2.02(b)

of this Agreement. Upon proper surrender of an Old Certificate for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificates shall be entitled to receive in exchange therefore (i) a New Certificate representing that number of whole shares of United Common Stock that such holder has the right to receive pursuant to Article IV, if any, (ii) a check representing the amount of the cash that such holder is entitled to receive pursuant to Article IV, if any, (iii) a check representing the amount of any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificates surrendered pursuant to the provisions of this Article IV, and (iv) any payment required by Section 2.02(b), and the Old Certificates so surrendered shall forthwith be cancelled.

(c) Neither the Exchange Agent, if any, nor any party hereto shall be liable to any former holder of Premier Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(d) No dividends or other distributions with respect to United Common Stock with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate representing shares of Premier Common Stock converted in the Merger into the right to receive shares of such United Common Stock until the holder thereof shall be entitled to receive New Certificates in exchange therefore in accordance with the procedures set forth in this Section 4.05. After becoming so entitled in accordance with this Section 4.05, the record holder thereof also shall be entitled to receive any such dividends or other distributions by the Exchange Agent, without any interest thereon, which theretofore had become payable with respect to shares of United Common Stock such holder had the right to receive upon surrender of the Old Certificates.

(e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Premier for twelve months after the Effective Time shall be paid to United. Any stockholders of Premier who have not theretofore complied with this Article IV shall thereafter look only to United for payment of the Merger Consideration, cash in lieu of any fractional shares and unpaid dividends and distributions on United Common Stock deliverable in respect of each share of Premier Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

4.06 Anti-Dilution Provisions. In the event United changes (or establishes a record date for changing) the number of shares of United Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, reverse stock split, stock dividend, reorganization, recapitalization or similar transaction with respect to the outstanding United Common Stock and the record date therefore shall be prior to the Effective Date, or shall establish a record date prior to the Effective Date with respect to any dividend or other distribution in respect of the United Common Stock other than a cash dividend consistent with past practice, the Exchange Ratio shall be proportionately adjusted.

4.07 Options. (a) At the Effective Time, each outstanding option (each, a “Premier Stock Option”) to purchase shares of Premier Common Stock under any and all plans of Premier under which stock options have been granted and are outstanding (collectively, the “Premier Stock Plans”) shall vest pursuant to the terms thereof and shall be converted into an option (each, a “Replacement Option”) to acquire, on the same terms and conditions as were applicable under

such Premier Stock Option (other than any requirement that an option be exercised within a specific time period after termination of employment or cessation of service as a non-employee director which requirement shall be waived or deleted from each option by amendment thereto), the number of shares of United Common Stock equal to (a) the number of shares of Premier Common Stock subject to the Premier Stock Option, multiplied by (b) the Exchange Ratio. Such product shall be rounded to the nearest whole number. The exercise price per share (rounded to the nearest whole cent) of each Replacement Option shall equal (y) the exercise price per share for the shares of Premier Common Stock which were purchasable pursuant to such Premier Stock Option divided by (z) the Exchange Ratio. Notwithstanding the foregoing, each Premier Stock Option which is intended to be an “incentive stock option” (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code. At or prior to the Effective Time, Premier shall use its reasonable best efforts, including using its reasonable best efforts to obtain any necessary consents from optionees, with respect to the Premier Stock Plans to permit the replacement of the outstanding Premier Stock Options by United pursuant to this Section and to permit United to assume the Premier Stock Plans. Premier shall further take all action necessary to amend the Premier Stock Plans to eliminate automatic grants or awards thereunder following the Effective Time. At the Effective Time, United shall assume the Premier Stock Plans; provided, that such assumption shall be only in respect of the Replacement Options and that United shall have no obligation with respect to any awards under the Premier Stock Plans other than the Replacement Options and shall have no obligation to make any additional grants or awards under such assumed Premier Stock Plans.

(b) At all times after the Effective Time, United shall reserve for issuance such number of shares of United Common Stock as necessary so as to permit the exercise of options granted under the Premier Stock Plans in the manner contemplated by this Agreement and the instruments pursuant to which such options were granted. United shall make all filings required under federal and state securities laws no later than the Effective Time so as to permit the exercise of such options and the sale of the shares received by the optionee upon such exercise at and after the Effective Time and United shall continue to make such filings thereafter as may be necessary to permit the continued exercise of options and sale of such shares.

4.08 Dissenters’ Rights. If applicable, shares of Premier Common Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders 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 the VSCA (collectively, the “Dissenters’ Shares”) shall not be converted into or represent the right to receive the Merger Consideration. Such stockholders instead shall be entitled to receive payment of the appraised value of such shares held by them in accordance with the provisions of the VSCA, except that all Dissenters’ Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or otherwise lost their rights to appraisal of such shares under the VSCA 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 4.05 of the Old Certificates that, immediately prior to the Effective Time, evidenced such shares.

7.01 Reasonable Best Efforts. Subject to the terms and conditions of this Agreement, each of Premier and United agrees to use its reasonable best efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, so as to permit consummation of the Merger as promptly as practicable and otherwise to enable consummation of the transactions contemplated hereby and shall cooperate fully with the other party hereto to that end.

7.02 Stockholder Approvals. Premier agrees to take, in accordance with applicable law and the Premier Certificate and Premier By-laws, all action necessary to convene an appropriate meeting of its stockholders to consider and vote upon the approval of this Agreement and any other matters required to be approved by Premier’s stockholders for consummation of the Merger (including any adjournment or postponement, the “Premier Meeting”), as promptly as practicable after the Registration Statement is declared effective. The Premier Board will recommend that the Premier stockholders approve and adopt the Agreement and the transactions contemplated hereby, provided that the Premier Board may fail to make such recommendation, or withdraw, modify or change any such recommendation, if the Premier Board, after having consulted with and considered the advice of outside counsel, has determined that the making of such recommendation, or the failure to withdraw, modify or change such recommendation, would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Premier Board under applicable law.

7.03 Registration Statement. (a) United agrees to prepare a registration statement on Form S-4 (the “Registration Statement”) to be filed by United with the SEC in connection with the issuance of United Common Stock in the Merger (including the prospectus of United and proxy solicitation materials of Premier constituting a part thereof (the “Proxy Statement”) and all related documents). Premier and United agree to cooperate, and to cause their respective Subsidiaries to cooperate, with the other and its counsel and its accountants in the preparation of the Registration Statement and the Proxy Statement; and provided that Premier and its Subsidiaries have cooperated as required above, United agrees to file the Registration Statement (including the Proxy Statement in preliminary form) with the SEC as promptly as reasonably practicable and in any event within seventy-five (75) days from the date of this Agreement. Each of Premier and United agrees to use all reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after filing thereof. United also agrees to use all reasonable efforts to obtain, prior to the effective date of the Registration Statement, all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement. Premier agrees to furnish to United all information concerning Premier, its Subsidiaries, officers, directors and stockholders as may be reasonably requested in connection with the foregoing and shall have the right to review and consult with United and approve the form of, and any characterization of such information included in, the Registration Statement prior to its being filed with the SEC.

(b) Each of Premier and United agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, 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, and (ii) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the time of the Premier Meeting, as the case may be, 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 or any statement which, in the light of the circumstances under which such statement is made, will be false or misleading with respect to any material fact, or which will omit to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier statement in the Proxy Statement or any amendment or supplement thereto. Each of Premier and United further agrees that if it shall become aware prior to the Effective Date of any information furnished by it that would cause any of the statements in 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 to take the necessary steps to correct the Proxy Statement.

(c) United agrees to advise Premier, promptly after United 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 United Stock for offering or sale in any jurisdiction, of the initiation or 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.

7.04 Press Releases. Each of Premier and United agrees that it will not, without the prior approval of the other party, file any material pursuant to SEC Rules 165 or 425, or issue any press release or written statement for general circulation relating to the transactions contemplated hereby, except as otherwise required by applicable law or regulation or NASDAQ rules.

7.05 Access; Information. (a) Each of Premier and United agrees that upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall afford the other party and the other party’s officers, employees, counsel, accountants and other authorized representatives, such access during normal business hours throughout the period prior to the Effective Time to the books, records (including, without limitation, tax returns and work papers of independent auditors), properties, personnel and to such other information as any party may reasonably request and, during such period, it shall furnish promptly to such other party (i) a copy of each material report, schedule and other document filed by it pursuant to the requirements of federal or state securities or banking laws, and (ii) all other information concerning the business, properties and personnel of it as the other may reasonably request.

(b) Each agrees that it will not, and will cause its representatives not to, use any information obtained pursuant to this Section 7.05 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) for any purpose unrelated to the consummation of the transactions contemplated by this Agreement. Subject to

the requirements of law, each party will keep confidential, and will cause its representatives to keep confidential, all information and documents obtained pursuant to this Section 7.05 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) unless such information (i) was already known to such party, (ii) becomes available to such party from other sources not known by such party to be bound by a confidentiality obligation, (iii) is disclosed with the prior written approval of the party to which such information pertains or (iv) is or becomes readily ascertainable from published information or trade sources. In the event that this Agreement is terminated or the transactions contemplated by this Agreement shall otherwise fail to be consummated, each party shall promptly cause all copies of documents or extracts thereof containing information and data as to another party hereto to be returned to the party which furnished the same. No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to either party’s obligation to consummate the transactions contemplated by this Agreement.

(c) During the period from the date of this Agreement to the Effective Time, each party shall promptly furnish the other with copies of all monthly and other interim financial statements produced in the ordinary course of business as, the same shall become available.

(d) The provisions of this Section 7.05 are in addition to, and not in lieu of, that certain letter agreement dated January 9, 2007, between the parties (the “Letter Agreement”), the terms of which are hereby specifically confirmed.

7.06 Acquisition Proposals. Premier agrees that it shall not, and shall cause its Subsidiaries and its Subsidiaries’ officers, directors, agents, advisors and affiliates not to, solicit or encourage inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential information to, any person relating to, any Acquisition Proposal. It shall immediately cease and cause to be terminated any activities, discussions or negotiations conducted prior to the date of this Agreement with any parties other than United with respect to any of the foregoing and shall use its reasonable best efforts to enforce any confidentiality or similar agreement relating to an Acquisition Proposal. Premier will inform United promptly of all relevant details of any inquiries or contacts by third parties relating to the possible disposition of the business or the capital stock of Premier or any merger, change or control or other business combination involving Premier. Notwithstanding the foregoing, if, at any time the Premier Board determines in good faith, after consultation with outside counsel, that failure to do so would be reasonably likely to constitute a breach of its fiduciary duties under applicable law, Premier, in response to a written Acquisition Proposal that was unsolicited or that did not otherwise result from a breach of this Section 7.06, may furnish non-public information with respect to Premier to the Person who made such Acquisition Proposal and participate in negotiations regarding such Acquisition Proposal.

7.07 Affiliate Agreements. (a) Not later than the 15th day prior to the mailing of the Proxy Statement, Premier shall deliver to United a schedule of each person that, to the best of its knowledge, is or is reasonably likely to be, as of the date of the Premier Meeting, deemed to be an “affiliate” of Premier (each, a “Premier Affiliate”) as that term is used in Rule 145 under the Securities Act.

No party hereto shall take any action that would cause the transactions contemplated by this Agreement subject to requirements imposed by any Takeover Law and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement from any applicable Takeover Law, as now or hereafter in effect.

7.09 Certain Policies. Immediately prior to the Effective Date, Premier shall, consistent with generally accepted accounting principles and on a basis mutually satisfactory to it and United, modify and change its loan, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of United and shall make appropriate accruals for any employee benefits, plans, arrangements or obligations assumed by United under this Agreement; provided, however, that Premier shall not be obligated to take any such action pursuant to this Section 7.09 unless and until United acknowledges that all conditions to its obligation to consummate the Merger have been satisfied and certifies to Premier that United’s representations and warranties, subject to Section 6.02, are true and correct as of such date and that United is otherwise material in compliance with this Agreement. Premier’s representations, warranties and covenants contained in this Agreement shall not be deemed to be untrue or breached in any respect for any purpose as a consequence of any modifications or changes undertaken solely on account of this Section 7.09.

7.10 Regulatory Applications. (a) United and Premier and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts to prepare all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement. Each of United and Premier shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to, all material written information submitted to any third party or any Governmental Authority in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable. Each party hereto agrees that it will consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby.

7.11 Indemnification. (a) Following the Effective Date and for a period of six years thereafter, United shall indemnify, defend and hold harmless the present directors, officers and employees of Premier and its Subsidiaries (each, an “Indemnified Party”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement) to the fullest extent that Premier is permitted or required to indemnify (and advance expenses to) its directors and officers under the laws of the Commonwealth of Virginia, the Premier Certificate, the Premier By-Laws and any agreement as in effect on the date hereof; provided that any determination required to be made with respect to whether an officer’s, director’s or employee’s conduct complies with the standards set forth under Virginia law, the Premier Certificate, the Premier By-Laws and any agreement shall be made by independent counsel (which shall not be counsel that provides material services to United) selected by United and reasonably acceptable to such officer or director.

(b) For a period of six (6) years from the Effective Time, United shall use its reasonable best efforts to provide that portion of director’s and officer’s liability insurance that serves to reimburse the present and former officers and directors of Premier or any of its Subsidiaries (determined as of the Effective Time) (as opposed to Premier) with respect to claims against such directors and officers arising from facts or events which occurred before the Effective Time, which insurance shall contain at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage currently provided by Premier; provided, however, that in no event shall United be required to expend more than 200 percent of the current amount expended by Premier (the “Insurance Amount”) to maintain or procure such directors and officers insurance coverage; provided, further, that if United is unable to maintain or obtain the insurance called for by this Section 7.11(b), United shall use its reasonable best efforts to obtain as much comparable insurance as is available for the Insurance Amount; provided, further, that officers and directors of Premier or any Subsidiary may be required to make application and provide customary representations and warranties to United’s insurance carrier for the purpose of obtaining such insurance.

(c) Any Indemnified Party wishing to claim indemnification under Section 7.11(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify United thereof; provided that the failure so to notify shall not affect the obligations of United under Section 7.11(a) unless and to the extent that United is actually prejudiced as a result of such failure.

(d) If United or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any entity, then and in each case, proper provision shall be made so that the successors and assigns of United shall assume the obligations set forth in this Section 7.11.

(e) The provisions of this Section 7.11 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.

7.12 Benefit Plans. (a) It is the intention of United that within a reasonable period of time following the Effective Time (i) it will provide employees of Premier with employee benefit plans substantially similar in the aggregate to those provided to similarly situated employees of United, (ii) United shall cause any and all pre-existing condition limitations (to the extent such limitations did not apply to a pre-existing condition under the Compensation and Benefit Plans) and eligibility waiting periods under group health plans to be waived with respect to such participants and their eligible dependents, and (iii) all Premier employees will receive credit for years of service with Premier and its predecessors prior to the Effective Time for purposes of eligibility and vesting (but not for purposes of benefit accrual) under United’s benefit plans. United shall maintain Premier’s existing employee benefit plans until such time as United has provided similar plans to Premier’s employees as contemplated in the preceding sentence. Premier employees shall not be entitled to accrual of benefits or allocation of contributions under United’s benefit plans based on years of service with Premier and its predecessors prior to the Effective Date.

(b) United agrees that each Premier employee who is involuntarily terminated by United (other than for cause) within six (6) months of the Effective Date, shall receive a severance payment equal to two (2) weeks of base pay (at the rate in effect on the termination date) for each year of service at Premier (with credit for partial years of service), with a maximum payment equal to twenty-six (26) weeks of base pay.

(c) Immediately prior to the Effective Date, Premier shall take such action as may be necessary to terminate its 401(k) plan. Following the receipt of a favorable determination letter from the IRS relating to the termination of the 401(k) plan, the assets of the plan shall be distributed to participants as provided in the plan. In the event a favorable ruling is not issued, Premier agrees that termination of the 401(k) plan shall not occur and the 401(k) plan shall be merged with United’s 401(k) plan.

7.13 Notification of Certain Matters. Each of Premier and United shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

7.14 Directors and Officers. (a) United agrees to cause one (1) individual from Premier to be appointed as a director of United at the Effective Time. The individual shall be chosen by United.

United acknowledges that the consummation of the Merger will constitute a “change-in-control” of Premier for purposes of any employee benefit plans, agreements and arrangements of Premier.

7.15 Current Public Information. United agrees that it shall, for a period of three (3) years following the Effective Time, use its best efforts to meet the current public information requirements as set forth in paragraph (c) of Rule 144 promulgated under the Securities Act, and will provide those persons providing affiliate letters pursuant to Section 7.07 with such other information as they may reasonably require and to otherwise cooperate with such persons to facilitate any sales of United Common Stock issued to such persons pursuant to this Agreement in compliance with the provisions of Rule 144 and/or Rule 145 promulgated under the Securities Act. The provisions of this Section 7.15 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, such affiliates of Premier.

(b) Breach. At any time prior to the Effective Time, by United or Premier (provided that the party seeking termination is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if its Board of Directors so determines by vote of a majority of the members of its entire Board, in the event of either: (i) a breach by the other party of any representation or warranty contained herein (subject to the standard set forth in Section 6.02), which breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach; or (ii) a breach by the other party of any of the covenants or agreements contained herein, which breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach, provided that such breach (whether under (i) or (ii)) would be reasonably likely, individually or in the aggregate with other breaches, to result in a Material Adverse Effect.

(d) No Approval. By Premier or United, if its Board of Directors so determines by a vote of a majority of the members of its entire Board, in the event (i) the approval of any

Governmental Authority required for consummation of the Merger and the other transactions contemplated by this Agreement shall have been denied by final nonappealable action of such Governmental Authority or (ii) any stockholder approval required by Section 8.01(a) herein is not obtained at the Premier Meeting.

(f) Decline in United Common Stock Price. By Premier, if the Premier Board so determines by a vote of the majority of the members of its entire board, at any time during the five-day period commencing with the Determination Date (as defined below), if both of the following conditions are satisfied:

(i) The number obtained by dividing the Average Closing Price by the Starting Price (each as defined below) (the “United Ratio”) shall be less than .80; and

(b) In the event that Premier shall fail to pay the Fee when due, the Fee plus the costs and expenses actually incurred or accrued by United (including, without limitation, fees and expenses of counsel) in connection with the collection of the Fee under the enforcement of this Section 9.03, together with interest on such unpaid Fee and costs and expenses, commencing on the date that the Fee became due, at a rate equal to the rate of interest publicly announced by Citibank, N.A., from time to time, in the City of New York, as such bank’s Base Rate plus 2.00%.

FORM OF AFFILIATE LETTER

, 2007

United Bankshares, Inc.

▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Attention:

▇▇▇▇▇▇ ▇▇▇▇▇▇,

Chief Financial Officer

Ladies and Gentlemen:

I have been advised that I may be deemed to be, but do not admit that I am, an “affiliate” of Premier Community Bankshares, Inc. a Virginia corporation (“PCBI”), as that term is defined in Rule 145 promulgated by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”). I understand that pursuant to the terms of the Agreement and Plan of Reorganization, dated as of , 2007 (the “Agreement”), by and between United Bankshares, Inc., a West Virginia corporation (“United”), and PCBI, PCBI plans to merge with and into a wholly-owned subsidiary of United (the “Merger”).

I further understand that as a result of the Merger, I may receive shares of common stock, par value $ per share, of United (“United Stock”) in exchange for shares of common stock, par value $ per share, of PCBI (“PCBI Stock”).

I have carefully read this letter and reviewed the Agreement and discussed their requirements and other applicable limitations upon my ability to sell, transfer, or otherwise dispose of United Stock, to the extent I felt necessary, with my counsel or counsel for PCBI.

I represent, warrant and covenant with and to United that in the event I receive any United Stock as a result of the Merger:

1. I shall not make any sale, transfer, or other disposition of such United Stock unless (i) such sale, transfer or other disposition has been registered under the Securities Act, (ii) such sale, transfer or other disposition is made in conformity with the provisions of Rule 145 under the Securities Act (as such rule may be amended from time to time), or (iii) in the opinion of counsel in form and substance reasonably satisfactory to United, or under a “no-action” letter obtained by me from the staff of the SEC, such sale, transfer or other disposition will not violate or is otherwise exempt from registration under the Securities Act.

2. I understand that United is under no obligation to register the sale, transfer or other disposition of shares of United Stock by me or on my behalf under the Securities Act or to take any other action necessary in order to make compliance with an exemption from such registration available.

3. I understand that stop transfer instructions will be given to United’s transfer agent with respect to shares of United Stock issued to me as a result of the Merger and that there will be placed on the certificates for such shares, or any substitutions therefor, a legend stating in substance:

“The shares represented by this certificate were issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares represented by this certificate may be transferred only in accordance with the terms of a letter agreement, dated , between the registered holder hereof and United Bankshares, Inc., a copy of which agreement is on file at the principal offices of United Bankshares, Inc.”

4. I understand that, unless transfer by me of the United Stock issued to me as a result of the Merger has been registered under the Securities Act or such transfer is made in conformity with the provisions of Rule 145(d) under the Securities Act, United reserves the right, in its sole discretion, to place the following legend on the certificates issued to my transferee:

“The shares represented by this certificate have not been registered under the Securities Act of 1933 and were acquired from a person who received such shares in a transaction to which Rule 145 under the Securities Act of 1933 applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act of 1933 and may not be offered, sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act of 1933.”

It is understood and agreed that the legends set forth in paragraphs (3) and (4) above shall be removed by delivery of substitute certificates without such legends if I shall have delivered to United (i) a copy of a “no action” letter from the staff of the SEC, or an opinion of counsel in form and substance reasonably satisfactory to United, to the effect that such legend is not required for purposes of the Act, or (ii) evidence or representations satisfactory to United that the United Stock represented by such certificates is being or has been sold in conformity with the provisions of Rule 145(d).

I further understand and agree that this letter agreement shall apply to all shares of United Stock that I am deemed to beneficially own pursuant to applicable federal securities law.


Very truly yours,
