3.       Based on my knowledge,  the financial  statements,  and other financial

4.       The registrant's  other  certifying  officers and I are responsible for
         establishing  and  maintaining  disclosure  controls and procedures (as

         have:

         a)   designed  such  disclosure  controls and  procedure to ensure that

         performing the equivalent function):

         a)   all  significant  deficiencies  in  the  design  or  operation  of
              internal  controls which could adversely  affect the  registrant's
              ability to record,  process,  summarize and report  financial data
              and have  identified  for the  registrant's  auditors any material
              weaknesses in internal controls; and
