Item 5.  OTHER EVENTS.

                  On or about September 30, 2003, the Registrant will cause the
         issuance and sale of approximately $589,218,132 initial principal
         amount of Bear Stearns Asset Backed Securities Trust 2003-AC5,
         Asset-Backed Certificates, Series 2003-AC5 (the "Certificates")
         pursuant to a Pooling and Servicing Agreement to be dated as of
         September 1, 2003, between the Registrant as depositor, EMC Mortgage
         Corporation, as seller and company, Wells Fargo Bank Minnesota,
         National Association, as master servicer and securities administrator
         and JPMorgan Chase Bank, as trustee.

                  In connection with the sale and the Series 2003-AC5, Class
         A-1, Class A-2, Class A- 3, Class A-4, Class M-1, Class M-2, and Class
         B Certificates (the "Underwritten Certificates"), the Registrant has
         been advised by Bear, Stearns & Co. Inc. (the "Underwriter"), that the
         Underwriter has furnished to prospective investors certain
         computational materials (the "Computational Materials") with respect to
         the Underwritten Certificates following the effective date of
         Registration Statement No. 333-91334, which computational Materials are
         being filed as exhibits to this report.

                  The Computational Materials have been provided by the
         Underwriter. The information in the Computational Materials 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         preliminary and may be superseded by the Prospectus Supplement relating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 Computational Materials 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 Computational Materials may be based on
         assumptions that differ from the assumptions set forth in the
         Prospectus Supplement. The Computational Materials may not include, and
         do not purport to include, information based on assumptions
         representing a complete set of possible scenarios. Accordingly, the
         Computational Materials may not be relevant to or appropriate for
         investors other than those specifically requesting them.

                  In addition, the actual characteristics and performance of the
         mortgage loans underlying the Underwritten Certificates (the "Mortgage
         Loans") may differ from the assumptions used in the Computational
         Materials, which are hypothetical in nature and which were provided to
         certain investors only to give a general sense of how the yield,
         average life, duration, expected maturity, interest rate sensitivity
         and cash flow characteristics of the Underwritten Certificates might
         vary under varying prepayment and other scenarios. Any difference
         between such assumptions and the actual characteristics and performance
         of the Mortgage Loans will affect the actual yield, average life,
         duration, expected maturity, interest rate sensitivity and cash flow
         characteristics of the Underwritten Certificates.
