| | (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
