           statement of a material fact or omit to state a material fact
           necessary to make the statements made, in light of the circumstances

           for, the periods presented in this report;

     4.    The registrant's other certifying officer and I are responsible for
           establishing and maintaining disclosure controls and procedures (as

                 such disclosure controls and procedures to be designed under

                 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)   Designed such internal control over financial reporting, or
                 caused such internal control over financial reporting to be
                 designed under our supervision, to provide reasonable assurance
                 regarding the reliability of financial reporting and the
                 preparation of financial statements for external purposes in
                 accordance with generally accepted accounting principles;

           (c)   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 a date within 90 days prior to the filing
                 date of this report based on such evaluation; and

           (d)   Disclosed in this report any change in the registrant's
                 internal control over financial reporting that occurred during
                 the second fiscal quarter of the period covered by this 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 to the
           registrant's auditors and the audit committee of the registrant's
           board of Trustees (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
