         a)  Designed such disclosure controls and procedures, or caused such

             case of an annual report) that has materially affected, or is
             reasonably likely to materially affect, the Funds' internal control
             over financial reporting; and

5. The Funds' other certifying officer(s) and I have disclosed to the Funds'

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