      2.    Based on my  knowledge,  this  report  does not  contain  any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made, not misleading with respect to the period covered by this report;

      4.    The small  business  issuer's  other  certifying  officer  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 small
business issuer 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 small
      business issuer, 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 small  business  issuer's
      disclosure  controls  and  procedures  and  presented  in this  report our

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

      5.    The small  business  issuer's  other  certifying  officer and I have
disclosed,  based  on our  most  recent  evaluation  of  internal  control  over
financial  reporting,  to the small  business  issuer's  auditors  and the audit
committee  of the  small  business  issuer'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 small business issuer'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  small  business
      issuer's internal control over financial reporting.
