     accountant.

          or the committee.

9.   Review with management and the independent  accountant at the completion of
     the annual examination:

     a.   The company's  annual financial  statements,  related  footnotes,  and

          regulators.

     b.   The independent accountant's audit of the financial statements and the
          resulting report.

          communicated  to  the  committee  under  generally  accepted  auditing
          standards.
