               business issuer;

          2.   Based on my knowledge, this quarterly report does not contain any
               untrue statement of a material fact or omit to state a material
               fact necessary to make the statements made, in light of the
               circumstances under which such statements were made, not
               misleading with respect to the period covered by this quarterly
               report;

          3.   Based on my knowledge, the financial statements, and other
               financial information included in this quarterly report, fairly
               present in all material respects the financial condition, results
               of operations and cash flows of the small business issuer as of,
               and for, the periods presented in quarterly report;

                    relating to the small business issuer, including its
                    consolidated subsidiaries, is made known to us by others
                    within those entities, particularly during the period in
                    which this report is being prepared;

               (b)  Designed such internal control over financial reporting, or
                    caused such internal control over financial reporting to be
                    designed under our supervision, to provide reasonable
                    assurance regarding the reliability of financial reporting
                    and the preparation of financial statements for external
                    purposes in accordance with generally accepted accounting
                    principles;

               (c)  Evaluated the effectiveness of the small business issuer's
                    disclosure controls and procedures and presented in this

                    disclosure controls and procedures, as of the end of the
                    period covered by this report based on such evaluation; and

               (d)  Disclosed in this report any change in the small business
                    issuer internal financial reporting that occurred during the
                    small business issuer's most recent fiscal quarter (the
                    small business issuer's fourth fiscal quarter in the case of
                    an annual report) that has materially affected, or is
                    reasonable likely to materially affect, the small business
                    issuer's internal control over the financial reporting; and

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