4.    The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined

      a)    designed such disclosure controls and procedures, or caused
      such disclosure controls and procedures to be designed under one
      supervisor, to ensure that material information relating to the

      us by others within those entities, particularly during the period in
      which this report is being prepared;

      affected, or is reasonably likely to materially affect, the
      registrant's internal control over financial reporting; and

based on our most recent evaluation of internal control over financial
reporting, to the registrant's auditors and the audit committee of

      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
