To fulfill its responsibilities and duties, the Audit Committee shall:

1. Be directly responsible for the appointment, compensation, retention and oversight of the work of any registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Corporation, and each such registered public accounting firm must report directly to the Audit Committee.

5. Obtain, on an annual basis, a formal written statement from the independent auditor affirming their independence (as required by applicable standards of the Public Company Accounting Oversight Board or its successor) and delineating all relationships between the auditor and the Corporation that may reasonably be thought to bear on such independence. Discuss with the auditor any disclosed relationships or services that may impact the objectivity and independence of the auditor and take, or recommend that the Board take, appropriate action to oversee the independence of the independent auditor.

6. Following completion of the annual audit, review separately with the independent auditor, the internal auditing department, if any, and management any significant difficulties encountered during the course of the audit.

8. Retain independent counsel, experts and other advisors as the Audit Committee determines necessary to carry out its duties.

9. Receive appropriate funds, as determined by the Audit Committee, from the Corporation for payment of (i) compensation to any registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Corporation, (ii) compensation to any independent counsel, experts and other advisors employed by the Audit Committee, and (iii) ordinary administrative expenses of the Audit Committee that are necessary or appropriate in carrying out its duties.

10. Review and approve all "related-party transactions" as such term is defined in Item 404 of Regulation S-K.

11. Prepare the report of the Audit Committee required to be included in the Corporation's annual proxy statement.

14. Perform any other activities consistent with this Charter, the Corporation's Bylaws, Nasdaq rules and governing law, as the Audit Committee or the Board deems necessary or appropriate, including, without limitation, the delegation of authority to one or more members of the Audit Committee of authority to carry out certain activities set forth hereunder.
