      4.    The Company's other certifying officer(s) and I are responsible

                  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;

            b.    Evaluated the effectiveness of the Company's disclosure

            c.    Disclosed in this report any change in the Company's
                  internal control over financial reporting that occurred
                  during the Company's most recent fiscal quarter (the
                  Company's fourth fiscal quarter in the case of an 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(s) 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.
