                disclosure controls and procedures to be designed under our

                internal control over financial reporting that occurred during
                such registrant's most recent fiscal quarter that has materially
                affected, or is reasonably likely to materially affect, such
                registrant's internal control over financial reporting; and

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

                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 such registrant's
