reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant 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 registrant, including its
consolidated subsidiaries, is made known to us by others within those entities,

            (b) Evaluated the effectiveness of the registrant's disclosure

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

financial reporting, to the registrant's auditors and the audit committee of the
registrant's board of directors (or persons performing the equivalent
functions):

            (a) All significant deficiencies and material weaknesses in the

reasonably likely to adversely affect the registrant's ability to record,
process, summarize and report financial information; and

other employees who have a significant role in the registrant's internal control
over financial reporting.
