misleading with respect to the period covered by this report;

registrant and have:

     a)  Designed such disclosure controls and procedures, or
     caused such disclosure controls and procedures to be
     designed under our supervision, to ensure that material

     which this report is being prepared;

     b)  Designed such internal control over financial reporting,
     or caused such internal control over financial reporting to

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

     reporting; and

     report financial information; and

     b)  Any fraud, whether or not material, that involves
     management or other employees who have a significant role in
     the registrant's internal control over financial reporting.
