                      make the

                      such statements
                      were made, not misleading with respect to the period covered

                      information
                      included in this report, fairly present in all material respects

                  The
                      registrant’s other certifying officer(s) and I are responsible for
                      establishing and maintaining disclosure controls and procedures
                      (as
                      defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for
                      the registrant
                      and 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 report is being prepared;
 
 (b)  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
 
 (c)  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 (the
              registrant’s fourth fiscal quarter in the case of an annual report) 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(s) 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 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 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.
