responsible for establishing and maintaining  disclosure controls and procedures
(as  defined  in  Exchange  Act Rules  13a-15(e)  and  15d-15(e))  for the small
business issuer and have:

              (a) designed such disclosure  controls and  procedures,  or caused
         such  disclosure  controls  and  procedures  to be  designed  under our

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

         5. The small  business  issuer's other  certifying  officers and I have

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 the small business  issuer'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 small  business
         issuer's internal control over financial reporting.
