              untrue statement of a material fact or omit to state a material
              fact necessary to make the statements made, in light of the

4)            The small business issuer'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 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

               c)   Evaluated the  effectiveness of the small business  issuer'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
               d)   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 officers 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.
