WHEREAS, as a condition and material inducement to Buyer entering into the Merger Agreement, the Shareholder has agreed to enter into and perform this Agreement.

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

1.	Agreement to Vote.

During the term of this Agreement and at the AMNB Meeting or at any other meeting of the shareholders of AMNB, however called, including any adjournment or postponement thereof, and in connection with any written consent of the shareholders of AMNB (collectively, the “AMNB Shareholder Meeting”), the Shareholder irrevocably and unconditionally agrees that it shall, in each case to the fullest extent that such matters are submitted for the vote or written consent of the Shareholder and that the Shares are entitled to vote thereon or consent thereto:

(a) appear at each AMNB Shareholder Meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) to vote (or cause to be voted) or deliver (or cause to be delivered) a written consent covering, all of the Shares, and to cause any holder of record of the Shares to vote all such Shares, in person or by proxy: (i) in favor of the approval of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Mergers, and any actions required in furtherance thereof, at the AMNB Shareholder Meeting; and (ii) against (A) any Acquisition Proposal, (B) any action, proposal, transaction or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of AMNB under the Merger Agreement or of the Shareholder under this Agreement, and (C) any action, proposal, transaction or agreement that is intended or could reasonably be expected to impede, interfere with, delay, discourage, adversely affect, frustrate the purposes of, or inhibit the timely consummation of the Mergers or the other transactions contemplated by the Merger Agreement or this Agreement or the fulfillment of AMNB’s or Buyer’s obligations or conditions under the Merger Agreement.

2.	Representations and Warranties and Covenants of Shareholder.

The Shareholder represents, warrants, covenants and/or agrees as follows:

(a) Ownership. The Shareholder is the beneficial owner of the Existing Shares, and all of the Shares owned by the Shareholder from the date hereof through and on the Closing Date will be beneficially owned by the Shareholder, in each case, subject to Section 13.1-662H of the Virginia Stock Corporation Act, as amended (the “VSCA”). Except for the Existing Shares, the Shareholder is not the beneficial or registered owner with Sole Authority of any other shares of AMNB Common Stock or rights to acquire shares of AMNB Common Stock as of the date hereof. The Shareholder has and will have, at all times through the Closing Date, (i) sole voting power, including the right to control such vote as contemplated herein, (ii) sole power of disposition, including the right to control any disposition, (iii) sole power to issue instructions with respect to the matters set forth in Section 1 hereof, including the right to control the making or issuing any such instructions, and (iv) sole power to agree to all of the matters set forth in this Agreement, including the right to cause such agreements (clause (i) through (iv), collectively, “Sole Authority”), in each case, with respect to all of the Shares, subject to Section 13.1-662H of the VSCA. The Shareholder has possession of an outstanding certificate or outstanding certificates representing all of the Shares (other than Shares held at the Depository Trust Company and/or in book-entry form) and such certificate or certificates does or do not contain any legend or restriction inconsistent with the terms of this Agreement, the Merger Agreement or the transactions contemplated hereby and thereby. For purposes of this Agreement, the term “beneficial ownership” and correlative terms shall be interpreted in accordance with Rule 13d-3 under the Exchange Act.

(b) Restrictions on Transfer. During the term of this Agreement, the Shareholder will not (i) sell, pledge, hypothecate, tender, grant a security interest in, transfer or otherwise dispose of or grant or create a Lien in or upon, or gift or place in trust, any of the Shares and will not offer to make such a sale, transfer or other disposition or enter into any agreement, arrangement or understanding (other than a proxy for the purpose of voting the Shareholder’s Shares in accordance with Section 1 hereof) which would during that term (A) restrict, (B) establish a right of first refusal to, or (C) otherwise relate to, the transfer of the Shares (including transfer by testamentary or intestate succession or otherwise by operation of law) or any right, title or interest in the Shares (including, but not limited to, any right or power to vote to which the Shareholder may be entitled, whether such right or power is granted by proxy or otherwise) or the record of legal or beneficial ownership of the Shares (“Transfer”), (ii) except as otherwise permitted by this Agreement or by order of a court of competent jurisdiction, take any action that could restrict or otherwise affect the Shareholder’s legal power, authority and right to vote all of the Shares then beneficially owned by him or her, or otherwise comply with and perform his or her covenants and obligations under this Agreement, or (iii) publicly announce any intention to do any of the foregoing. Any Transfer in violation of this provision shall be void. The Shareholder understands and agrees that if the Shareholder attempts to Transfer, vote or provide any other person with the authority to vote any of the Shares other than in compliance with this Agreement, AMNB shall not, and the Shareholder hereby unconditionally and irrevocably instructs AMNB to not (i) permit such Transfer on its books and records, (ii) issue a new certificate representing any of the Shares, or (iii) record such vote unless and until the Shareholder shall have complied with the terms of this Agreement.

(c) Authority. The Shareholder has full power, authority and legal capacity to enter into, execute and deliver this Agreement and to perform fully the Shareholder’s obligations hereunder. This Agreement has been duly and validly executed and delivered by the Shareholder and constitutes the legal, valid and binding obligation of the Shareholder, enforceable against the Shareholder in accordance with its terms.

(d) No Liens. The Shareholder has good and marketable title to the Shares and the Shares and the certificates representing any of the Shares are now, and at all times during the term of this Agreement, will be, held by the Shareholder, or by a nominee or custodian for the benefit of the Shareholder, free and clear of all pledges, liens (statutory or other), mortgages, security interests, charges, options to purchase, leases, claims, proxies, voting trusts or agreements, understandings or arrangements or any other encumbrances of any kind or any preference, priority or other security agreement or preferential arrangement of any kind or nature whatsoever (including any conditional sale or other title retention agreement) (each, a “Lien”), except for (i) any Liens arising hereunder, and (ii) Liens, if any, which have been disclosed on Schedule B attached hereto.

(e) No Breach. None of the execution and delivery of this Agreement nor the performance by the Shareholder of his or her obligations hereunder will result in a violation of, or a default under, result in the creation of any Liens on the assets of the Shareholder or conflict with, any law, order, contract, loan and credit arrangements, Liens, trust, commitment, agreement, understanding, arrangement or restriction of any kind to which the Shareholder is a party or bound or to which the Shares are subject.

(f) No Prior Proxies. Except as contemplated by this Agreement, neither the Shareholder nor any of his or her affiliates has entered into any voting agreement or voting trust with respect to any Shares or entered into any other arrangement relating to the voting of the

Shares. Any prior proxies or voting rights previously given by the Shareholder in respect of the Shares are revocable, and the Shareholder covenants that any such proxies or voting rights are hereby irrevocably revoked.

(g) Consents and Approvals. The execution and delivery of this Agreement by the Shareholder does not, and the performance by the Shareholder of his or her obligations under this Agreement and the consummation by him or her of the transactions contemplated hereby will not, require the Shareholder to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any third party or Governmental Entity. No consent or approval of Shareholder’s spouse is necessary under any “community property” or other laws in order for Shareholder to enter into and perform its obligations under this Agreement.

(h) Absence of Litigation. There is no suit, action, investigation or proceeding pending or, to the knowledge of the Shareholder, threatened against or affecting the Shareholder or any of his or her affiliates before or by any Governmental Entity that could reasonably be expected to impair the ability of the Shareholder to perform his or her obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

(i) Statements. The Shareholder shall not make any statement, written or oral, to the effect that he or she does not support the Mergers or that other shareholders of AMNB should not support the Mergers.

Except for this Agreement, the Shareholder shall not (i) enter into at any time while this Agreement remains in effect, any voting agreement or voting trust or any other agreement, arrangement or understanding with respect to the Shares, (ii) grant at any time while this Agreement remains in effect, a proxy, consent or power of attorney in contravention of the obligations of the Shareholder under this Agreement with respect to the Shares, (iii) commit any act that could restrict or affect his or her legal power, authority and right to vote any of the Shares then held of record or beneficially owned by the shareholder or otherwise reasonably be expected to prevent or disable the Shareholder from performing any of his or her obligations under this Agreement, (iv) take any action that would reasonably be expected to make any representation or warranty of the Shareholder contained herein untrue or incorrect or have the effect of impeding, preventing, delaying, interfering with, disabling or adversely affect the performance by, the Shareholder from performing any of his or her obligations under this Agreement, and (v) publicly announce any intention to do any of the foregoing.

(k) Further Assurances. From time to time, at the request of AMNB or Buyer and without further consideration, the Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary to effect the actions and consummate the transactions contemplated by this Agreement.

Notwithstanding anything in this Agreement to the contrary, with respect to the terms of this Agreement relating to the Shares, this Agreement relates solely to the capacity of the Shareholder as a shareholder or other beneficial owner of the Shares and is not in any way intended to affect or prevent the exercise by the Shareholder of his or her responsibilities as a director or officer of AMNB, as applicable, to the extent permitted by the Merger Agreement or required by law.
