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

3.         Based on my knowledge, the financial statements, and other financial

                    and the preparation of financial statements for external
                    purposes in accordance with generally accepted accounting

               (d)  Disclosed in this report any change in the registrant's
                    internal control over financial reporting that occurred
                    during the registrant's most recent fiscal half-year (the
                    registrant's second fiscal half-year in the case of an
                    annual report) that has materially affected, or is
                    reasonably likely to materially affect, the registrant's
                    internal control over financial reporting; and

5.         The registrant's other certifying officers and I have disclosed 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
                    design or operation of internal control over financial
                    reporting which are reasonably likely to adversely affect
                    the registrant's ability to record, process, summarize, and
                    report financial information; and

               (b)  Any fraud, whether or not material, that involves management
