      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
            small business issuer, including its consolidated subsidiaries, is

            business issuer's internal control over financial reporting; and

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

            information; and

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