Collateral Term Sheets

                  Deutsche Bank Securities Inc. (the "Underwriter") has advised
         the Registrant that it has furnished to certain prospective purchasers
         of Certificates certain materials ("Collateral Term Sheets") in written
         form, which are in the nature of data tables.

                  The Collateral Term Sheets have been provided by the
         Underwriter. The information in the Collateral Term Sheets is
         preliminary and may be superseded by the Prospectus Supplement relating
         to the Certificates and by any other information subsequently filed
         with the Securities and Exchange Commission.

                  The Collateral Term Sheets were prepared by the Underwriter at
         the request of certain prospective investors, based on assumptions
         provided by, and satisfying the special requirements of, such
         prospective investors. The Collateral Term Sheets may be based on
         assumptions that differ from the assumptions set forth in the
