    Company (the "Registrant");

2. Based on my knowledge, this report does not contain any untrue statement of

4. The Registrant's other certifying officer and I are responsible for

           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;

           b) designed such internal control over financial reporting, or
              caused such internal control over financial reporting to be

              regarding the reliability of financial reporting and the
              preparation of financial statements for external purposes in
              accordance with generally accepted accounting principals;

           c) evaluated the effectiveness of the Registrant's disclosure
              controls and procedures and presented in this report our

              and procedures, as of a date within 90 days prior to the filing
              date of this report based on such evaluation; and



           d) disclosed in this report any change in the Registrant's internal
              control over financial reporting that occurred during the second
              fiscal quarter of the period covered by this 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 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 or
              other employees who have a significant role in the Registrant's
              internal control over financial reporting.
