A shareholder may also revoke his proxy at any time before it is exercised by filing a written notice with the Secretary of the Company or by submitting a proxy bearing a later date. Proxies will extend to, and will be voted at, any properly adjourned session of the Annual Meeting. If a shareholder specifies how the proxy is to be voted with respect to any proposal for which a choice is provided, the proxy will be voted in accordance with such specifications. If a shareholder fails to specify with respecthow the proxy is to Proposal 1 set forth in the accompanying notice and further described herein,be voted, the proxy will be voted FOR the director nominees named in Proposal 1.1, FOR Proposal 2 to amend the Company’s Articles of Incorporation to authorize the issuance of the preferred stock and to make a clarifying change, and FOR Proposal 3 to adjourn the Annual Meeting to allow time for further solicitation of proxies, in the event there are insufficient votes at the Annual Meeting to approve the amendment proposal.

Directions to Annual Meeting

To obtain directions to attend the Annual Meeting and vote in person, please contact the Secretary of the Company at (434) 369-3000.

Voting Rights of Shareholders

Only those shareholders of record at the close of business on February 19, 2008,24, 2009, are entitled to notice of and to vote at the Annual Meeting, or any adjournments thereof. The number of shares of common stock of the Company outstanding and entitled to vote at the Annual Meeting is 1,485,089. The Company has no other class of stock outstanding. A majority of the votes entitled to be cast, represented in person or by proxy, will constitute a quorum for the transaction of business. Each share of Company common stock entitles the record holder thereof to one vote upon each matter to be voted upon at the Annual Meeting.

Shares for which the holder has elected to abstain or to withhold the proxies’ authority to vote (including broker non-votes) on a matter will count toward a quorum, but will not be included in determining the number of votes cast with respect to such matter. With regard to the election of directors, votes may be cast in favor or withheld. If a quorum is present, the nominees receiving the greatest number of affirmative votes cast at the Annual Meeting will be elected directors; therefore, votes withheld will have no effect. Thus, although abstentions and broker non-votes (shares held by customers which may not be voted on certain matters because the broker has not received specific instructions from the customer) are counted for purposes of determining the presence or absence of a quorum, they are not counted for purposes of determining whether a proposalnominee has been approvedelected and, therefore, will have no effect.

Solicitation of Proxies

The cost of solicitation of proxies will be borne by the Company. Solicitations will be made only by the use of the mails, except that officers and regular employees of the Company and The First National Bank of Altavista (the “Bank”) may make solicitations of proxies in person, by telephone or mail, acting without compensation other than their regular compensation. We anticipate that brokerage houses and other nominees, custodians, and fiduciaries will be requested to forward the Company’s proxy soliciting material to the beneficial owners of the stock held of record by such persons, and the Company will reimburse them for their charges and expenses in connection with this activity.

Benefits are estimated on the basis that each will continue to receive, until age 65, covered salary in the same amount paid in 2007.2008.

Profit Sharing/401(k) Plan. The Bank adopted a Defined Contribution Profit Sharing Thrift Plan (the “Thrift Plan”) effective January 1, 1997. The Thrift Plan, sponsored by the Virginia Bankers Association Benefits Corporation,VBA, includes a 401(k) savings provision that authorizes a maximum voluntary salary deferral of up to 100% of compensation, subject to statutory limitations. All full-time employees who have reached the age of 21 are eligible to participate. Contributions and earnings, which are tax-deferred, may be invested in various investment vehicles offered through the Virginia Bankers Association Benefits Corporation.VBA. The profit sharing arrangement allows for employer contributions in such amounts, if any, as the Board of Directors determines. Employees become 100% vested in any employer contributions that may be made after three plan years of service. The Bank made no contributions to the Thrift Plan for the year ended December 31, 2007.2008.

Based on a review of these reports filed by the Company’s officers and directors, the Company believes that its officers and directors complied with all filing requirements under Section 16(a) of the Securities Exchange Act of 1934 during 2007.2008, except Mr. Arthur who reported two transactions late on a Form 5, Mr. Waller who reported one transaction late on a Form 5, and Mr. Hall who made a late Form 3 filing.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors, which consists entirely of directors who meet the independence requirements of applicable SEC regulations and the NASDAQ Stock Market’s listing standards for audit committee members, has furnished the following report:

The Audit Committee (the “Committee”) reviews the Company’s financial reporting process on behalf of the Board. The role and responsibilities of the Committee are set forth in a written charter adopted by the Board. The Committee reviews the charter annually and, when appropriate, recommends changes to the Company’s Board. The charter was last amended in 2004. Management has the primary responsibility for the consolidated financial statements and the reporting process, including the system of internal controls. The independent auditors are responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with accounting principles generally accepted in the United States of America and to issue a report thereon. The Committee monitors these processes.

- 13 -

In this context, the Committee met and held discussions with management and the independent auditors to discuss the consolidated audited financial statements for the year ended December 31, 2007.2008. Management represented to the Committee that the Company’s audited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, and the Committee reviewed and discussed the consolidated financial statements with management and the independent auditors. The Committee also discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees), as amended, including their judgments about the quality, not just the acceptability, of the Company’s accounting principles and underlying estimates in the Company’s consolidated financial statements; all critical accounting policies and practices to be used; all alternative treatments within generally accepted accounting principles for policies and practices related to material items that have been discussed with management of the Company; and other material written communications between the independent auditors and the management of the Company, such as any management letter or schedule of unadjusted differences.

The Committee alsoreceived the written disclosures and the letter from the independent auditors required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the Committee concerning independence, and discussed with the independent auditors the auditors’ independence from the Company and its management, and the independent auditors provided to the Committee the written disclosures and letter required by the Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees).management.

The Committee also discussed with the Company’s internal and independent auditors the overall scope and plans for their respective audits. The Committee met with the internal and independent auditors, with and without management present, to discuss the results of their examinations, the evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

- 13 -

Based on the reviews and discussions referred to above, the Committee recommended to the Board of Directors, and the Board of Directors has approved, that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007,2008, for filing with the SEC.

PRINCIPAL ACCOUNTANT

The Audit Committee has selected the firm of Cherry, Bekaert & Holland, L.L.P. as the Company’s independent registered public accounting firm to audit the books of the consolidated Company for the current year, to report on the consolidated statement of financial position and related statement of earnings of the Company, and to perform such other appropriate accounting services as may be required by the Audit Committee. Cherry, Bekaert & Holland, L.L.P. audited the books of the consolidated Company for 2007.2008. A representative of Cherry, Bekaert & Holland, L.L.P. is expected to be present at the Annual Meeting and will be given the opportunity to make a statement if he so desires, and to respond to appropriate questions of the shareholders.

- 14 -

PRINCIPAL ACCOUNTANT FEES

The following table presents fees for professional audit services rendered by Cherry, Bekaert & Holland, L.L.P. for the audit of the Company’s annual financial statements for the years ended December 31, 20072008 and 20062007 and fees billed for other services rendered by Cherry, Bekaert & Holland, L.L.P. during those periods.

All such audit and non-audit services were pre-approved by the Audit Committee, which concluded that the provision of such services by Cherry, Bekaert & Holland, L.L.P. was compatible with the maintenance of that firm’s independence in the conduct of their auditing functions.

- 14 -

Pre-Approval Policies

The Audit Committee reviews and pre-approves all auditing services and permitted non-audit services performed by the Company’s independent auditors, as well as corresponding fees, subject to the de minimis exception for permitted non-audit services described in Section 10A(i)(1)(B) of the Exchange Act which are approved by the committee prior to the completion of the audit.

The Audit Committee may form and delegate authority to, when appropriate, subcommittees consisting of one or more members, including the authority to grant pre-approvals of audit and permitted non-audit services, provided that decisions of such subcommittee to grant pre-approvals are presented to the committee at its next scheduled meeting.

PROPOSAL 2:

AMENDMENT OF ARTICLES OF INCORPORATION TO AUTHORIZE 1,000,000 SHARES OF PREFERRED STOCK AND TO MAKE A CLARIFYING CHANGE

The Proposed Amendment

Our Board of Directors has adopted an amendment of our Articles of Incorporation to authorize 1,000,000 shares of preferred stock, par value $3.00 per share (the “Preferred Stock”) and to make a clarifying change. The exact text of the proposed amendment is contained in Appendix A to this proxy statement.

- 15 -

Authorize Preferred Stock. Our Articles of Incorporation currently authorize only the issuance of common stock. The amendment will vest in the Board of Directors the authority to issue the Preferred Stock in one or more series and, to the extent permitted by law, fix and determine the preferences, limitations and relative rights of the shares of any series so established. Provisions in a company’s Articles of Incorporation authorizing preferred stock in this manner will give a board of directors the flexibility, at any time or from time to time, without further shareholder approval (except as may be required by applicable laws, regulatory authorities or the rules of any stock exchange on which our securities are then listed), to create one or more series of preferred stock and to determine by resolution the terms of each such series.

Clarifying change. While asking shareholders to approve an amendment to the Articles of Incorporation to authorize the issuance of Preferred Stock, the Board of Directors determined that a clarifying change should be made to Article VI of the Articles of Incorporation at the same time. This clarifying change adds language to Article VI regarding the shareholder approval required for certain transactions to clarify that such shareholder approval requirements apply only to the extent shareholder approval is required by applicable law or regulation.

Shareholders are being asked to approve the proposed amendment to authorize the issuance of Preferred Stock and to make this clarifying change to the Articles of Amendment at the Annual Meeting.

Reasons for the Amendment

As mentioned above, our Articles of Incorporation currently do not authorize the Company to issue preferred stock. The Board of Directors believes that the authorization of the Preferred Stock is advisable and in the best interests of the Company and its shareholders for several reasons. The Board believes that the complexity of modern business financing and possible future transactions require greater flexibility in our capital structure than currently exists. If Proposal 2 is approved, the Board would be permitted to issue the Preferred Stock without further shareholder approval, in one or more series, and with such dividend rates and rights, liquidation preferences, voting rights, conversion rights, rights and terms of redemption and other rights, preferences, and privileges as determined by the Board. Being able to issue Preferred Stock in this manner would provide the Company with maximum flexibility in structuring acquisitions, joint ventures, strategic alliances and capital-raising transactions and for other corporate purposes. The Board of Directors evaluates such opportunities and considers different capital structuring alternatives designed to advance our business strategy. Having the authority to issue the Preferred Stock will enable us to develop equity securities tailored to specific purposes and to avoid the possible delay associated with, and significant expense of, calling and holding a special meeting of shareholders to authorize such additional capital. The Board of Directors believes that such enhanced ability to respond to opportunities and favorable market conditions before the opportunities or conditions pass is in the best interests of the Company and its shareholders.

If Proposal 2 is approved, the Board would be permitted to issue Preferred Stock from time to time for any proper corporate purpose, including acquisitions of other businesses or properties and the raising of additional capital. Shares of Preferred Stock could be issued publicly or privately, in one or more series that could rank senior to our common stock with respect to dividends and liquidation rights.

The Company has no present plans for the issuance of Preferred Stock. On December 8, 2008, the Company filed a conditional application for preliminary approval under the Capital Purchase Program (the “Program”) established by the United States Department of the Treasury (the “Treasury”) pursuant to the Emergency Economic Stabilization Act of 2008. Under the Program, eligible financial institutions could generally apply to issue

- 16 -

Senior Preferred to the Treasury in aggregate amounts of between 1% and 3% of the institution’s risk-weighted assets. The Company was prompted to file its conditional application by the fact that the Program had a deadline for such applications of December 8, 2008, and the Company wished to preserve the option of participating in the Program as an alternative available to it. Since that time, the matter has been further considered, and the Company has decided not to participate in the Program and the conditional application has been withdrawn. Therefore, the Company has no present plans, understandings or agreements for, and we are not engaged in any negotiations that will involve, the issuance of Preferred Stock. The consideration of the possibility of participating in the Program caused us to focus on the fact that our current Articles of Incorporation do not authorize the issuance of Preferred Stock, and prompted us to seek the additional flexibility to do so for the reasons we have described above. Therefore, we recommend that shareholders approve Proposal 2.

Effects of the Amendment on the Rights of Holders of Common Stock

We are unable to determine the effects of any future issuance of a series of Preferred Stock on the rights of our shareholders until the Board of Directors determines the rights of the holders of such series. However, such effects might include: (i) restrictions on the payment of dividends to holders of our common stock; (ii) dilution of voting power to the extent that the holders of shares of preferred stock are given voting rights; (iii) dilution of the equity interests and voting power of holders of our common stock if the preferred stock is convertible into common stock; (iv) restrictions upon any distribution of assets to the holders of our common stock upon liquidation or dissolution and until the satisfaction of any liquidation preference granted to the holders of preferred stock; (v) continuation of our current management; and (vi) prevention of mergers with or business combinations by us and discouragement of possible tender offers for shares of our common stock.

Upon conversion of convertible Preferred Stock into shares of our common stock, the voting power and percentage ownership of holders of our common stock before such conversion would be diluted, and such issuances could have an adverse effect on the market price of our common stock. Additionally, the issuance of shares of Preferred Stock with certain rights, preferences and privileges senior to those held by our common shareholders could diminish their rights to receive dividends, if declared by the Board, and to receive payments upon our liquidation.

- 17 -

Potential Anti-Takeover Effects of the Amendment

The amendment of the Articles of Incorporation as proposed could adversely affect the ability of third parties to take over or change the control of the Company by, for example, permitting issuances that would dilute the stock ownership of a person seeking to effect a change in the composition of our Board

- 18 -

of Directors or contemplating a tender offer or other transaction for the combination of the Company with another company. Specifically, the ability of our Board of Directors to establish the rights of, and to cause us to issue, substantial amounts of Preferred Stock without the need for shareholder approval, upon such terms and conditions, and having such rights, privileges and preferences, as our Board of Directors may determine from time to time in the exercise of its business judgment, may, among other things, be used to create voting impediments with respect to changes in control of the Company or to dilute the stock ownership of holders of common stock seeking to obtain control of the Company. The rights of the holders of common stock will be subject to, and may be adversely affected by, any Preferred Stock that may be issued in the future. The issuance of Preferred Stock, while providing desirable flexibility in connection with possible acquisitions, financings and other corporate transactions, may have the effect of discouraging, delaying or preventing a change in control of the Company.

Any future issuance of Preferred Stock, however, would require approval by the Board of Directors, and each director is legally bound to act in accordance with his or her good faith business judgment of the best interests of the Company. The Board of Directors has no present intention of issuing any Preferred Stock for any defensive or anti-takeover purpose, for the purpose of implementing any shareholder rights plan or with features specifically intended to make any attempted acquisition of the Company more difficult or costly.

At present, our Articles of Incorporation and Bylaws contain the following provisions that may have an anti-takeover effect:

Special Voting Provisions. Our Articles of Incorporation currently provide that approval of an amendment to the Articles of Incorporation, merger or share exchange to which we are party, or direct or indirect sale, lease, exchange or other disposition of all or substantially all of our property, otherwise than in the usual and regular course of business, shall be approved by: (a) a majority of the shares entitled to be cast by each voting group entitled to vote on such action, if such action has been approved by at least two-thirds of the directors; or (b) more than two-thirds of the shares entitled to be cast by each voting group entitled to vote on such action, if such action has not been approved by at least two-thirds of the directors.

Our Articles of Incorporation do not provide for cumulative voting in the election of directors.

Advance Notice for Shareholder Proposals or Nominations at Meetings. Our Bylaws prescribe the procedure a shareholder must follow to nominate directors for a shareholders’ meeting. For a shareholder to nominate a candidate for director at an annual meeting of shareholders, notice of the nomination must be received by the Company’s Secretary at the Company’s principal office in Altavista, Virginia, not less than 30 days prior to the anniversary of the initial mailing of the notice for the prior year’s annual meeting, provided that such notice will not be required to be given more than 90 days prior to the date of the annual meeting. The notice must describe various matters regarding the nominee and the shareholder giving the notice.

Our Bylaws also prescribe the procedures a shareholder must follow to bring other business before shareholders’ meetings. For a shareholder to bring other business before the annual meeting of shareholders, notice of the proposal must be received by the Company’s Secretary at the Company’s principal office in Altavista, Virginia, not less than 120 days prior to the anniversary of the initial mailing of the notice for the prior year’s annual meeting, provided that if the date of the annual meeting is more than 30 days from the date of the anticipated annual meeting at the time of the initial notice for the prior

- 19 -

year’s annual meeting, the deadline for such a proposal is a reasonable time before the Company prints its proxy materials for the annual meeting. The notice must include a description of the proposed business, the reasons therefore, and other specified matters.

Required Vote

The affirmative vote of the holders of a majority of the shares outstanding and entitled to vote at the Annual Meeting is required for approval of the proposed amendment of our Articles of Incorporation. Accordingly, abstentions and broker non-votes will count as votes against this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS

THAT SHAREHOLDERS VOTE “FOR” PROPOSAL 2 TO

AMEND THE ARTICLES OF INCORPORATION.

PROPOSAL 3:

ADJOURNMENT OF THE ANNUAL MEETING

General

If at the Annual Meeting the number of shares of our common stock present or represented and voting in favor of Proposal 2 is insufficient to approve Proposal 2, our management may move to adjourn the Annual Meeting in order to enable our Board of Directors to continue to solicit additional proxies in favor of the Proposal 2. In that event, you will be asked to vote on the adjournment proposal but not Proposal 2.

In this proposal, we are asking you to authorize the holder of any proxy solicited by our Board of Directors to vote in favor of adjourning the Annual Meeting and any later adjournments. If our shareholders approve the adjournment proposal, we could adjourn the Annual Meeting, and any adjourned session of the Annual Meeting, to use additional time to solicit additional proxies in favor of Proposal 2, including the solicitation of proxies from the shareholders that have previously voted. Among other things, approval of the adjournment proposal could mean that, even if proxies representing a sufficient number of votes against the Proposal 2 have been received, we could adjourn the Annual Meeting without a vote on Proposal 2 and seek to convince the holders of those shares to change their votes to votes in favor of the approval of Proposal 2.

The Board of Directors believes that if the number of shares of common stock present or represented at the Annual Meeting and voting in favor of Proposal 2 is insufficient to approve that proposal, it is in the best interests of the shareholders to enable the Board of Directors, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes to approve Proposal 2.

Generally, if the Annual Meeting is adjourned, no notice of the adjourned meeting is required to be given to shareholders, other than an announcement at the Annual Meeting of the place, date and time to which the meeting is adjourned. However, if the Annual Meeting is adjourned to a date more than 120 days after the date fixed for the original meeting, notice of the adjourned meeting will be given as in the case of the original meeting.

Required Vote

The affirmative vote of the holders of a majority of shares voted on this proposal is required for approval of the proposal to adjourn the Annual Meeting. Accordingly, abstentions and broker non-votes will have no effect on the outcome of this proposal.

- 20 -

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS

THAT SHAREHOLDERS VOTE “FOR” PROPOSAL 3 TO ADJOURN THE ANNUAL

MEETING TO ALLOW TIME FOR THE FURTHER SOLICITATION OF PROXIES TO

APPROVE THE AMENDMENT OF THE ARTICLES OF INCORPORATION.

OTHER BUSINESS

As of the date of this Proxy Statement, management of the Company has no knowledge of any matters to be presented for consideration at the Annual Meeting other than those referred to above. If any other matters properly come before the Annual Meeting, the persons named in the accompanying proxy intend to vote such proxy, to the extent entitled, in accordance with the determination of a majority of the Board of Directors.

FORWARD-LOOKING STATEMENTS

Certain information contained in this Proxy Statement may include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. These forward-looking statements are generally identified by phrases such as “we expect,” “we believe,” or words of similar import. Such forward-looking statements involve known and unknown risks including but not limited to:
