               internal  control over  financial  reporting  that  occurred
               during the period  covered  by the  annual  report  that has
               materially  affected,  or is reasonably likely to materially
               affect,   the  company's  internal  control  over  financial
               reporting; and

     5.   The  company's  other  certifying  officer and I have  disclosed,
          based on our most  recent  evaluation  of internal  control  over
          financial  reporting,  to the  company's  auditors  and the audit
          committee  of  the  company's  board  of  directors  (or  persons
          performing the equivalent functions):

          a.   All significant  deficiencies and material weaknesses in the
               design or  operation  of  internal  control  over  financial
               reporting  which are reasonably  likely to adversely  affect

               report financial information; and

          b.   Any fraud, whether or not material, that involves management
