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;

3.  Based  on my  knowledge,  the  financial  statements,  and  other  financial

4. The small business issuer'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))  and  internal  control  over
financial  reporting (as defined in Exchange Act Rules  13a-15(f) and 15d-15(f))
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,

     within those entities,  particularly during the period in which this report
     is being prepared;

     b. Designed such internal control over financial reporting,  or caused such
     internal  control  over  financial  reporting  to  be  designed  under  our
     supervision,  to provide reasonable  assurance regarding the reliability of
     financial  reporting  and  the  preparation  of  financial  statements  for
     external  purposes  in  accordance  with  generally   accepted   accounting
     principles;

     c. Evaluated the  effectiveness of the small business  issuer's  disclosure

     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 officer(s) 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.
