2)       Based on my knowledge, this quarterly 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

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-14 and 15d-14) for the
         small business issuer and have:
a)       Designed such disclosure controls and procedures 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 quarterly

         controls and procedures and presented in this report our conclusion

         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 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

         employees who have a significant role in the small business issuer's
         internal control over financial reporting.
