     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

                  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, based on

     the registrant's auditors and the audit committee of 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.
