     were made, not misleading with respect to the period covered by this

     financial reporting (as defined in Exchange Act Rules 13a-15(f) and

     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

          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 under

          to materially affect, the issuer's internal control over financial
          reporting; and

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