     in Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

          entities,  particularly  during the period in which this annual report

          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  officers 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
