               second fiscal half-year in the case of an annual report) that has
               materially  affected,  or  is  reasonably  likely  to  materially

directors (or persons performing the equivalent functions):

     a)   All significant  deficiencies and material  weakness in the design  or
          operation of internal  controls  over  financial  reporting  which are
          reasonably  likely to  adversely  affect the  registrant's  ability to
