Annual Performance Evaluation - ----------------------------- The Audit Committee shall conduct an annual self-evaluation of the Audit Committee's performance. Responsibility and Processes - ---------------------------- The primary responsibility of the Audit Committee is to oversee the Corporation's financial reporting process on behalf of the Board of Directors and report the results of its activities to the Board of Directors. It is not the duty of the Audit Committee to plan or conduct audits, to determine that the Corporation's financial statements are complete and accurate and are in accordance with generally accepted accounting principles or to assure compliance with laws. These are the responsibilities of management, the internal auditor, and the independent auditor. The following shall be the principal recurring processes of the Audit Committee in carrying out its oversight responsibilities. The processes are set forth as a guide with the understanding that the Audit Committee may alter or supplement them as appropriate. 1. Annually, the Audit Committee shall recommend to the Board of Directors the selection of the Corporation's independent auditor, subject to stockholder ratification of the selection, if such ratification is required or sought. 2. The Audit Committee shall discuss with the internal auditors and independent auditor the overall scope and plans for their respective audit examinations. The Audit Committee shall be responsible for the compensation, retention, and oversight of the work of the independent auditor (including resolution of any disagreements between management and the auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or performing other audit, review, or attest services for the Corporation. 3. The Audit Committee shall ensure that the independent auditor submits annually a formal written statement delineating all relationships between the independent auditor and the Corporation.

The Audit Committee should review the auditor's qualifications, performance, and independence. This evaluation should include the review and evaluation of the lead partner of the independent auditor. In making its evaluation, the Audit Committee should take into account the opinions of management and the Corporation's internal auditors. In addition to assuring the regular rotation of the lead audit partner as required by law, the Audit Committee should further consider whether, in order to assure continuing auditor independence, there should be regular rotation of the audit firm itself. The Audit Committee should present its conclusions with respect to the independent auditor to the Board of Directors of the Corporation. 2 7. The Audit Committee shall discuss with management, the internal auditors, and the independent auditor the adequacy and effectiveness of the Corporation's internal controls, accounting and financial records, and the system for monitoring and managing business risk and legal compliance.
