the quarter ended September 30, 2007;

2. Based on my knowledge, this report does

4. The small business issuer's other certifying officer 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

(a) designed such disclosure controls and procedures,

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

in this report any change in the small business issuer's internal control over

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 audit committee
of the small business issuer's board of directors (or persons performing the
