                    relating to the small business issuer, including its
                    consolidated subsidiaries, is made known to us by others

                    fiscal quarter (the registrant's fourth fiscal quarter in
                    the care of 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

                    summarize and report financial information; and

               b.   any fraud, whether or not material, that involves management
