         statement of a material fact or omit to state a material fact necessary

         disclosure   controls  and   procedures   to  be  designed   under  our

         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):

         operation  of  internal  control  over  financial  reporting  which are
         reasonably  likely to adversely affect the Company's ability to 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 Company's internal control
         over financial reporting.
