4. The registrant's other certifying officers 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 we 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 quarterly report is being
     prepared;

     of the disclosure controls and procedures based on our evaluation as of the

   of registrant's board of directors (or persons performing the equivalent
   function):

   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 officers and I have indicated in this
   quarterly report whether or not 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 regard to significant deficiencies and material
   weaknesses.
