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
quarterly report;

over  financial  reporting  (as  defined in  Exchange  Act Rules  13a-15(f)  and
15d-15(f)) 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

            (d) 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 small business issuer's internal control over financial
reporting; and

      5. The small  business  issuer'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 the

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.
