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

       4.     The registrant's other certifying officer and I are responsible
for establishing and maintaining disclosure controls and procedures (as defined
in Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

              a)     designed such disclosure controls and procedures 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 annual report is being prepared;

              b)     evaluated the effectiveness of the registrant's disclosure
                     controls and procedures as of a date within 90 days prior

based on our most recent evaluation, to the registrant's auditors and the audit
committee of registrant's board of directors (or persons performing the
equivalent functions):

              a)     all significant deficiencies in the design or operation of
                     internal controls which could adversely affect the
                     registrant's ability to record, process, summarize and
                     report financial data and have identified for the
                     registrant's auditors any material weaknesses in internal
                     controls; and

              b)     any fraud, whether or not material, that involves
                     management or other employees who have a significant role
                     in the registrant's internal controls; and

       6.     The registrant's other certifying officer and I have indicated in
this annual report whether there were significant changes in internal controls
or in other factors that could significantly affect internal controls subsequent
to the date of our most recent evaluation, including any corrective actions with
