            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

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this report, fairly present in all material

            defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
            company and have:

         (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 company, 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;

               controls and procedures and presented in this report our
               conclusions about the effectiveness of the 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 company's internal
               control over financial reporting that occurred during the
               period covered by the annual report that has materially
               affected, or is reasonably likely to materially affect, the
               company's internal control over financial reporting; and

      5.    The company's other certifying officer and I have disclosed, based
            on our most recent evaluation of internal control over financial
            reporting, to the company's auditors and the audit committee of the
            company'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
               company's ability to record, process, summarize and report
               financial information; and

         (b)   Any fraud, whether or not material, that involves management
               or other employees who have a significant role in the
               company's internal control over financial reporting.
