            controls  which  could  adversely  affect the  Company's  ability to
            record,  process,  summarize  and  report  financial  data  and have
            identified  for the  Company's  auditors any material  weaknesses in
            internal controls; and

            internal controls; and

6.    The Company's other certifying  officers,  if any, and I have indicated in
      this amended  annual  report  whether  there were  significant  changes in
      internal  controls or in other  factors  that could  significantly  affect
