1.3 Reviewing and Improving Process

10. Hold regular meetings on at least a quarterly basis and as otherwise may be necessary, and hold special meetings as may be called by the Chairman of the Audit Committee or at the request of the independent accountants.

As part of its job to foster open communication, the Committee should meet at least annually with the Corporation's management, the Corporation's directors of corporate audit and the independent accountants in separate executive sessions to discuss any matters that the Committee or each of these groups believe should be discussed confidentially.



In consultation with the independent accountants and the internal auditors, review the integrity and quality of the organization's financial reporting processes, both internal and external, and the independent accountant's perception of the Corporation's financial and accounting personnel.

On a quarterly basis, discuss the following with management and the independent accountants, if applicable:

a) all significant deficiencies in the design or operation of internal controls which could adversely affect the Corporation's ability to record, process, summarize and report financial data and any material weaknesses in internal controls; and

Perform any other activities consistent with this Charter, the Corporation's
By-laws and applicable law, as the Committee or the Board deems necessary or appropriate.




While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Corporation's financial statements are complete and accurate and are in accordance with generally accepted accounting principles. This is the responsibility of management and the independent auditors. Nor is it the duty of the Audit Committee to conduct investigations, to resolve disagreements, if any, between management and the independent auditors or to assure compliance with laws and regulations and the Corporation's Code of Conduct. In carrying out its responsibilities, the Committee's policies and procedures must remain flexible to enable the Committee to react to changing conditions and circumstances. The duties and responsibilities set forth above are intended to serve as a guide with the understanding that the Committee may supplement or diverge from them as appropriate.

* SAS 61 requires independent auditors to communicate certain matters related to the conduct of an audit to those who have responsibility for oversight of the financial reporting process, specifically the Audit Committee. Among the matters to be communicated to the Audit Committee are: (1) methods used to account for significant unusual transactions; (2) the effect of authoritative guidance or consensus; (3) the process used by management in formulating particularly sensitive accounting estimates and the basis for the accountant's conclusions regarding the reasonableness of those estimates; and (4) disagreements with management over the application of accounting principles, the basis for management's accounting estimates, and the disclosures in the financial statements.
