establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

registrant's   board  of  directors  (or  persons   performing   the  equivalent
functions):

     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

<PAGE>

     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
amended  annual  report  whether  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.
