               regarding  the   reliability  of  financial   reporting  and  the

               date of this report based on such evaluation; and

          d)   Disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the

               second fiscal half-year in the case of an annual report) that has
               materially  affected,  or  is  reasonably  likely  to  materially
               affect,   the   registrant's   internal  control  over  financial
               reporting; and

5.   The registrant's other certifying officer(s) and I have disclosed to the
     registrant's auditors and the audit committee of the registrant's Board of
     Trustees (or persons performing the equivalent functions):

          a)   All  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which are reasonably  likely to adversely affect the registrant's
               ability  to record,  process,  summarize,  and  report  financial
               information; and

          b)   Any fraud,  whether or not material,  that involves management or
