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 report;

3.            Based on my knowledge, the financial statements, and other
              financial information included in this report, fairly present in

4.            The registrant's other certifying officer and I are responsible

              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

                           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 and I have disclosed,

              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.
