         2. Based on my  knowledge,  this  report  does not  contain  any untrue

information included in this report, fairly present in all material respects the
financial  condition,  results of operations and cash flows of the registrant as

         4. The registrant's  other certifying  officer(s) 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) evaluated  the  effectiveness  of the  registrant's  disclosure
         controls and  procedures  and presented in this report our  conclusions
         about the effectiveness of the disclosure  controls and procedures,  as
         of the  end of  the  period  covered  by  this  report  based  on  such
         evaluation: and

              c)  disclosed  in  this  report  any  change  in the  registrant's
         internal  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 registrants  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  financial
reporting,  to the registrant's auditors and the audit committee of 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.
