         statement of a material fact or omit to state a material fact

         circumstances under which such statements were made, not misleading

         periods presented in this report;

4.       The registrant's other certifying officer(s) and I are responsible
         for establishing and maintaining disclosure controls and procedures
         (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
         registrant 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 registrant, 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;

                  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;

                  registrant's internal control over financial reporting
                  that occurred during the registrant's most recent fiscal
                  quarter (the registrant's fourth fiscal quarter 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 officer(s) and I have disclosed,
         based on our most recent evaluation of internal control over
         financial reporting, 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 or other employees who have a significant role
                  in the registrant's internal control over financial
                  reporting.
