III.	PURPOSE

        The purpose of the Committee is to represent the Board of Directors by

        The Committee shall review management's performance regarding financial
        reporting and shall make inquiry on a periodic basis of management, the
        internal auditors and the independent accountants with respect to the
        following:

           made in compliance with all applicable professional and regulatory
           requirements;

        B. whether an effective internal control structure has been
           established and maintained, including adequate policies and
           procedures over financial reporting, operations, and compliance
           with laws and regulations;

        C. whether the quality of internal and external audit efforts is
           adequate and the Company's public accountants are independent.

IV.	AUTHORITY

	The Committee is authorized by the Board of Directors to investigate
        any activity of the Company, which it deems relevant to the fulfillment
        of its responsibilities.  This authority shall include the right to
        initiate special or additional audits or investigations and retain
        special counsel or other outside experts to achieve the purpose of this
        charter.  All executives and employees are directed to cooperate as
        reasonably requested by members of the Committee or their designee.

V.	DUTIES AND RESPONSIBILITIES

        A. Financial Reporting and the Independent Accountants

           1. Recommend to the Board of Directors the appointment of the
              independent accountants to be engaged for the examination of the
              consolidated financial statements of the Company and its
              subsidiaries for each fiscal year.

           2. Review the independent accountants' proposed audit scope and
              approach, the fees therefor, and review and discuss the results
              of the audit for each fiscal year with the independent
              accountants, the head of Corporate Audit, and appropriate
              management representatives.

           3. Review the quarterly reporting process and the controls that
              management has established to protect the integrity of such
              process.  In doing so, the



                                        2







              Committee should discuss with the independent accountants their
              review of the Company's financial results prior to their release
              to the public, including but not limited to, the Company's Annual
              Report to shareholders, Forms 10-K and 10-Q and any other similar
              forms, as well as actual quarterly financial results that vary
              significantly from budgeted or projected results, significant
              transactions not a normal part of the Company's operations,
              changes, if any, during the year in the Company's accounting
              principles or their application, and significant adjustments
              proposed by the independent accountants.

           4. Review and discuss the statements from the independent
              accountants concerning any relationships between the independent
              accountants and the Company or any other relationships that may
              adversely affect the independence of the independent
              accountants, and based on such review, assess the independence
              of the independent accountants.

           5. Review and approve, in advance, management's plans for engaging
              the Company's independent accountants to perform non-audit
              services during the year.  Such review should involve both the
              types of services rendered and the applicable fees.  The
              Committee should weigh the effects such services may have on the
              continuing independence of the independent accountants.

           6. Maintain open lines of communication with the Company's
              principal financial officer and the head of Corporate Audit.

           7. Discuss with the independent accountants the matters required to
              be discussed by Statement on Auditing Standards No. 61 (as such
              Standard may be modified or supplemented) relating to the
              conduct of the audit.

        B. Oversight of Investment Committee

           1. Approve the members of the Investment Committee.

           2. Approve any hiring of external investment managers who are not

           4. Review and approve any exceptions to the Investment Guidelines

              Investment Committee.

           5. Review quarterly the investment performance of the Investment
              Department and external investment managers and significant
              changes in investment strategy.

           5. Review and approve the appointment or dismissal of the head of
              Corporate Audit.

        D. Other Responsibilities

           1. Provide a direct and, when necessary, confidential line of

           2. Establish and maintain procedures to receive and address
              complaints, including confidential submissions made by employees,

        E. Limits of Responsibility

           While the Committee has the responsibilities and powers set forth
           in this Charter, it is not the duty of the Committee to plan or

           of the Committee to conduct investigations, to resolve
           disagreements, if any, between management and the independent
           accountants or to ensure compliance with laws and regulations and
           the Company's internal rules, policies and codes of conduct.
