          disclosure   controls  and   procedures  to  be  designed   under  our

          in the case of an annual report) that has materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting; and

5.    The registrant's  other certifying  officer(s) and I have disclosed to the
      registrant's auditors and the audit committee of the registrant's board of
      directors (or persons performing the equivalent functions):

          operation  of internal  control  over  financial  reporting  which are

          record, process, summarize, and report financial information; and

      (b) Any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
