4.   The  registrant's  other  certifying  officer(s) and I are  responsible for

          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

          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
