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

prepared;

            (b) Designed such internal control over financial reporting, or

issuer's internal control over financial reporting; and

      5. The small business issuer's other certifying officer(s) and I have

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.
