(2)   Based on my knowledge, this report does not contain any untrue
      statement 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 quarterly report;

(3)   Based on my knowledge, the financial statements, and other financial

      registrant and we 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
          to us by others within those entities, particularly during the
          period in which this quarterly report is being prepared;

     (b)  [omitted in accordance with Section III.E. of SEC Release No.

     (c)  evaluated the effectiveness of the registrant's disclosure controls
          and procedures and presented in this report our conclusions about
          the effectiveness of the disclosure controls and procedures, as of
          the end of the period covered by this report based on such
          evaluation; 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 quarter 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 and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting,
     to the registrant's auditors and the Audit Committee of the registrant's
     Board of Directors (or persons with 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.
