     a material  fact or omit to state a  material  fact  necessary  to make the

     the registrant as of, and for, the periods presented in this report;

4.   The  registrant's  other  certifying  officers  and I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

     a)  designed  such  disclosure  controls  and  procedures,  or caused  such
         disclosure   controls  and   procedures   to  be  designed   under  our
         supervision,  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 report is being prepared;

     b)  [Paragraph omitted pursuant to SEC Release Nos. 33-8238 and 34-47986.]

         control over financial  reporting that occurred during the registrant's
         most recent fiscal quarter (the  registrant's  fourth fiscal quarter in
         the case of an  annual  report)  that has  materially  affected,  or is
         reasonably  likely to  materially  affect,  the  registrant's  internal
         control over financial reporting; and

5.   The registrant's other certifying  officers and I have disclosed,  based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's auditors and the audit committee of the registrant's board
     of directors (or persons performing the equivalent functions):

     a)  all significant  deficiencies and material  weaknesses in the design or
         operation  of  internal  control  over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the  registrant's  ability to
         record, process, summarize and report financial information; and

     b)  any fraud,  whether or not material,  that involves management or other
         employees  who have a  significant  role in the  registrant's  internal
         control over financial reporting.
