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

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

            period in which this report is being prepared;

      (c)   Disclosed in this report any change in the registrant's internal
            control over financial reporting that occurred during the
            registrant's most recent fiscal half-year (the registrant's second
            fiscal half-year 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 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
