    a.   designed such disclosure controls and procedures, or caused such
         disclosure controls or procedures to be designed under our supervision,
         to ensure that material information relating to the Company, including
         its consolidated subsidiaries, is made known to us by others within
         those entities, particularly during the period in which this quarterly
         report is being prepared;

    b.   [Omitted in accordance with SEC Release No. 33-8618.]

    d.   disclosed in this report any change in the Company's internal control
         over financial reporting that occurred during the Company's most recent

         reporting.

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 function):

    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.
