      have:

      a)    designed  such  disclosure  controls and  procedures  to ensure that
            material  information  relating  to the  registrant,  including  its
            consolidated  subsidiaries,  is made  known to us by  others  within
            those  entities,  particularly  during  the  period  in  which  this
            quarterly report is being prepared;

      b)    evaluated the effectiveness of the registrant's  disclosure controls

            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

      b)    any fraud,  whether or not  material,  that  involves  management or
            other  employees  who have a  significant  role in the  registrant's
            internal controls; and

6.    The  registrant's  other  certifying  officer and I have indicated in this
      annual report  whether or not there were  significant  changes in internal
      controls or in other  factors  that could  significantly  affect  internal
      controls  subsequent to the date of our most recent evaluation,  including
      any  corrective  actions  with  regard  to  significant  deficiencies  and
      material weaknesses.
