ended July 31, 2004 cannot be filed within the prescribed time period because
the Company is experiencing delays in the collection and compilation of certain

                  15(d) of the Securities Exchange Act of 1934 or Section 30 of
                  the Investment Company Act of 1940 during the preceding 12

                  If the answer is no, identify report(s)

                         [X] Yes                                  [ ] No

         (3)      Is it anticipated that any significant change in results of
                  operations from the corresponding period for the last fiscal
                  year will be reflected by the earnings statements to be
                  included in the subject report or portion thereof?

                         [X] Yes                                  [ ] No
