                               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

                               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 officers 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 function);

                       (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
