Appendix A

Wilson Bank Holding Company

Audit Committee Charter

1. Purpose

The purpose of the Audit Committee (the "Committee") of Wilson Bank Holding Company (the "Company") is to assist the Board of Directors (the "Board") with its oversight responsibilities regarding: (i) the integrity of the Company's financial statements; (ii) the integrity of the accounting and financial reporting processes of the Company and the audits of the financial statements; (iii) the Company's compliance with legal and regulatory requirements; (iv) the independent auditor's qualifications and independence; and (v) the performance of the Company's internal audit function and independent auditor. The Committee shall prepare the report required by the rules of the Securities and Exchange Commission (the "SEC") to be included in the Company's annual proxy statement.

In addition to the powers and responsibilities expressly delegated to the Committee in this Charter, the Committee may exercise any other powers and carry out any other responsibilities delegated to it by the Board from time to time consistent with the Company's bylaws. The powers and responsibilities delegated by the Board to the Committee in this Charter or otherwise shall be exercised and carried out by the Committee as it deems appropriate without requirement of Board approval, and any decision made by the Committee (including any decision to exercise or refrain from exercising any of the powers delegated to the Committee hereunder) shall be at the Committee's sole discretion. While acting within the scope of the powers and responsibilities delegated to it, the Committee shall have and may exercise all the powers and authority of the Board. To the fullest extent permitted by law, the Committee shall have the power to determine which matters are within the scope of the powers and responsibilities delegated to it.

Notwithstanding the foregoing, the Committee's responsibilities are limited to oversight. Management of the Company is responsible for the preparation, presentation and integrity of the Company's financial statements as well as the Company's financial reporting process, accounting policies, internal audit function, internal control over financial reporting and disclosure controls and procedures. The independent auditor is responsible for performing an audit of the Company's annual financial statements, expressing an opinion as to the conformity of such annual financial statements with generally accepted accounting principles and reviewing the Company's quarterly financial statements. It is not the responsibility of the Committee to plan or conduct audits or to determine that the Company's financial statements and disclosure are complete and accurate and in accordance with generally accepted accounting principles and applicable laws, rules and regulations. Each member of the Committee shall be entitled to rely on the integrity of those persons within the Company and of the professionals and experts (including the Company's internal auditor (or others responsible for the internal audit function, including contracted non-employee or audit or accounting firms engaged to provide internal audit services) (the "internal auditor") and the Company's independent auditor) from which the Committee receives information and, absent actual knowledge to the contrary, the accuracy of the financial and other information provided to the Committee by such persons, professionals or experts.

Further, auditing literature, particularly Statement of Accounting Standards No. 71, defines the term "review" to include a particular set of required procedures to be undertaken by independent auditors. The members of the Committee are not independent auditors, and the term "review" as used in this Charter is not intended to have that meaning and should not be interpreted to suggest that the Committee members can or should follow the procedures required of auditors performing reviews of financial statements.

1. Membership

The Committee shall consist of at least three members of the Board. Each Committee member must not have participated in the preparation of the financial statements of the Company or any current subsidiary of the Company at any time during the past three (3) years and must be able to read and understand fundamental financial statements, including the Company's balance sheet, income statement and cash flow statement. In addition, except

as may be acceptable to the Board, each Committee member shall satisfy the independence requirements of the New York Stock Exchange and Rule l0A-3(b)(l) under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

The members of the Committee, including the Chair of the Committee, shall be appointed by the Board. Committee members may be removed from the Committee, with or without cause, by the Board.

1. Meetings and Procedures

The Chair (or in his or her absence, a member designated by the Chair) shall preside at each meeting of the Committee and set the agendas for Committee meetings. The Committee shall have the authority to establish its own rules and procedures for notice and conduct of its meetings so long as they are not inconsistent with any provisions of the Company's bylaws that are applicable to the Committee.

The Committee shall meet at least once during each fiscal quarter and more frequently as the Committee deems desirable. The Committee shall meet separately, periodically, with management, with the internal auditor and with the independent auditor.

All non-management directors that are not members of the Committee may at the discretion of the Committee, attend and observe meetings of the Committee, but shall not be entitled to vote. The Committee may, at its discretion, include in its meetings members of the Company's management, representatives of the independent auditor, the internal auditor, any other financial personnel employed or retained by the Company or any other persons whose presence the Committee believes to be necessary or appropriate. Notwithstanding the foregoing, the Committee may also exclude from its meetings any persons it deems appropriate, including, but not limited to, any non-management director that is not a member of the Committee.

The Committee may retain any independent counsel, experts or advisors (accounting, financial or otherwise) that the Committee believes to be necessary or appropriate to carry out its duties. The Committee may also utilize the services of the Company's regular legal counsel or other advisors to the Company. The Company shall provide for appropriate funding, as determined by the Committee, for payment of compensation to the independent auditor for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Company and to any advisors employed by the Committee.

The Committee may conduct or authorize investigations into any matters within the scope of the powers and responsibilities delegated to the Committee.

The Committee shall be directly responsible and have sole authority for the appointment, compensation, retention and oversight of the work of the independent auditor (including resolution of any disagreements between Company management and the independent auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or related work or performing other audit, review or attest services for the Company, and the independent auditor shall report directly to the Committee.
2. Pre-Approvalof Services. Before the independent auditor is engaged by the Company or its subsidiaries to render audit or permissible non-audit services, the Committee shall preapprove the engagement.

   Company's engagement of the independent auditor, provided the policies and procedures are detailed as to the particular service, the Committee is informed of each service provided and such policies and procedures do not include delegation of the Committee's responsibilities under the Exchange Act to the Company's management. The
   Committee may delegate to one or more designated members of the Committee the authority to grant pre-approvals, provided such approvals are presented to the Committee at a subsequent meeting. If the Committee elects to establish pre-approval policies and procedures regarding non-audit services, the Committee must be informed of
