CHARTER OF THE AUDIT COMMITTEE

OF THE BOARD OF DIRECTORS

I. PURPOSE

The primary function of the Audit Committee is to assist the Board of Directors in fulfilling its oversight

responsibilities by reviewing:

• The financial reports, reports on internal controls, and other financial information provided by the

Corporation to its shareholders, the public, the SEC, NASDAQ and any other governmental or

regulatory body,

• The Corporation’s systems of internal controls regarding finance, accounting, legal compliance

(including disclosure controls and procedures and internal control over financial reporting) and

ethics that management and the Board have established; and

• The Corporation’s auditing, accounting and financial reporting processes generally.

The Audit Committee, to the extent consistent with this function should encourage continuous

improvement of, and should foster adherence to, the Corporation’s policies, procedures and practices at all

levels. The Audit Committee’s primary duties and responsibilities are to:

• Serve as an independent and objective party to monitor the Corporation’s financial reporting process

and internal control system.

• Retain and appraise the audit efforts of the Corporation’s independent auditors, determine the

compensation to be paid to the Corporation’s independent auditors, review and approve all non-audit

services to be performed by the Corporation’s independent auditors, and serve as the point of contact

for reports to be made by the independent auditors concerning the Corporation’s critical accounting

policies and practices and other communications relating to the Corporation’s financial matters.

• Review and appraise the audit efforts of the Corporation’s internal audit department.

• Provide an open avenue of communication among the Corporation’s independent auditors, financial

and senior management, the internal audit department, and the entire Board of Directors.

• Establish procedures to receive and respond to employees’ and others’ complaints and concerns

regarding the Corporation’s accounting and auditing matters.

The Audit Committee should fulfill these responsibilities primarily by carrying out the activities

enumerated in Section IV of this Charter.

II. COMPOSITION

The Audit Committee shall be comprised of three or more directors as determined by the Board, each of

whom shall be independent directors (as such term is now or hereafter defined by securities laws and SEC

and NASDAQ rules and regulations), and free from any relationship that, in the opinion of the Board,

would interfere with the exercise of his or her independent judgment as a member of the Committee. All

members of the Committee shall have a working familiarity with basic finance and accounting practices,

and at least one member of the Committee shall have accounting or related financial management expertise

(including, without limitation, at least one member who meets the definition of “audit committee financial

expert” as such term is defined by the SEC as required by the Sarbanes-Oxley Act of 2002). The Board

shall determine whether a director meets the definition of “audit committee financial expert,” and the

Corporation shall disclose the basis for the Board’s determination in accordance with applicable securities

laws and SEC and NASDAQ rules and regulations. No member of the Audit Committee may receive any

consulting, advisory or other compensatory fees from the Corporation (other than directors fees, which may

include a higher fee for serving on the Audit Committee). Committee members may enhance their

familiarity with finance and accounting by participating in educational programs conducted by the

Corporation or an outside consultant, including director education programs developed or required by

NASDAQ. The members of the Committee (and its chairperson) shall be elected by the Board at its annual

organizational meeting or at such other time as the Board may determine. Committee members shall serve

until their successors shall be duly elected and qualified.

III. MEETINGS

The Committee shall meet at least four times annually, or more frequently as circumstances dictate. As

part of its responsibility to foster open communication, the Committee shall meet at least quarterly with

management, the director of the internal audit department and the Corporation’s independent auditors in

separate executive sessions to discuss any matters that the Committee or any of these groups believe should

be discussed privately. In addition, the Committee or its Chair shall meet and consult with the independent

auditors and management quarterly to review the Corporation’s financial statements and other matters

consistent with IV below.

IV. RESPONSIBILITIES AND DUTIES

The Audit Committee’s policies and procedures should remain flexible in order to best react to changing

conditions and to ensure to the Board of Directors and shareholders that the accounting and reporting

practices of the Corporation are in accordance with all requirements and are of the highest quality.

In carrying out these responsibilities, the Audit Committee will:

Documents/Reports Review

1. Review and, if necessary, update this Charter periodically, at least annually, as conditions dictate.

2. Review the Corporation’s annual financial statements. Determine, based on review and discussion

of the audited financial statements with management and the independent auditors, whether the

Committee should recommend to the Board that the audited financial statements and any internal

control report be included in the Company’s Annual Report on Form 10-K.

3. Review the regular internal audit reports to management prepared by the internal audit department

and management’s response.

also ensure that the auditors meet all requirements for audit partner rotation under applicable

securities laws and SEC and NASDAQ rules and regulations, and shall monitor any hiring by the

Corporation of persons who were employed by the Corporation’s auditors to ensure that such

hiring does not adversely affect the auditors’ independence. When such rules become effective,

the Committee shall also ensure that the Corporation’s auditors are a “registered public accounting

firm” registered with the Public Company Accounting Oversight Board.

6. Pre-approve all auditing and permitted non-audit services to be provided by the independent

auditors (including determining whether any proposed non-audit services fall within the categories

of non-audit services prohibited under the Sarbanes-Oxley Act of 2002) with the exception of de

minimus non-audit services (as such term is defined in the Sarbanes-Oxley Act) which are

approved by the Committee prior to completion of the audit. The Committee may delegate preapproval

authority to one or more of its members, with the proviso that any decision taken by the

delegated members be presented to the Committee at its regular meetings. The Committee may

also adopt policies and procedures with respect to pre-approval of permitted non-audit services,

provided that such policies and procedures conform to the requirements set forth in applicable

laws, rules and regulations (including publication of the pre-approval policy).

and SEC and NASDAQ rules and regulations.
