      of a material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading with respect to the period covered by this

      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 company, including

        those entities, particularly during the period in which this report is
        being prepared;

        reporting; and

5.    The company's other certifying officer and I have disclosed, based on our
      most recent evaluation of internal control over financial reporting, to
      the company's auditors and the audit committee of the company'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 company'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 company's internal control
        over financial reporting.
