            statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances

                  caused such internal control over financial reporting to be

                  regarding the reliability of financial reporting and the
                  preparation of financial statements for external purposes in
                  accordance with generally accepted accounting principles;

            d)    Disclosed in this report any changes in the small business
                  issuers internal financial reporting that occurred during the
                  small business issuer's most recent fiscal quarter (the small
                  business issuers fourth quarter) that has materially affected
                  or is reasonably likely to materially affect, the small
                  business issuer's internal control over financial reporting.

      5.    The small business issuer's other certifying officers 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 function):

            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 data; and
            b)    Any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the small
