misleading with respect to the period covered by this report;

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

         which this report is being prepared;

         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  officer(s) and I have disclosed,  based on
our most recent evaluation of internal control over financing reporting,  to the

(or persons performing the equivalent function):


         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
