      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

            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 designed

            generally accepted accounting principles;

      c.    Evaluated the effectiveness of the registrant's disclosure

            and

      d.    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
