     others within those entities, particularly during the
     period in which this report is being prepared;

      b) Designed such internal control over financial

     reporting; and

5. The registrant's other certifying officer(s) and I have

       report financial information; and

     b)   Any fraud, whether or not material, that involves
       management or other employees who have a significant role in
