                                TRUST AGREEMENT

     THIS TRUST AGREEMENT dated as of June 1, 2000 (this "Agreement"), among

forth herein in full (this Agreement with the Standard Terms so incorporated,
the "Trust Agreement").

                             PRELIMINARY STATEMENT

    The Board of Directors of the Depositor has duly authorized the formation of
a trust (the "Trust") to issue a series of asset backed certificates with an
aggregate initial Certificate Principal Balance of $740,000,001 to be known as
the Saxon Asset Securities Trust 2000-2, Mortgage Loan Asset Backed

aggregate evidence the entire beneficial ownership in the Trust.  The
Certificates consist of the following:  the Class AF-1, Class AF-2, Class AF-3,
Class AF-4, Class AF-5, Class AF-6, Class MF-1, Class MF-2, Class BF-1, Class
BF-2, Class AV-1, Class MV-1, Class MV-2, Class BV-1, Class BV-2, Class A-IO,
Class PF-1, Class  PV-1, Class C and Class R Certificates.

    In accordance with Section 10.01 of the Standard Terms, the Trustee will
make elections to treat each of the segregated pools of assets described below
as a real estate mortgage investment conduit (each a "REMIC" or, in the
alternative, the POOLING REMIC, the SECOND-TIER REMIC, and the ISSUING REMIC.
The Certificates, other than the Class R Certificates, represent ownership of
the regular interests in the ISSUING REMIC for purposes of the REMIC Provisions.
The Class R Certificates represents ownership of the sole class of residual
interest in each of the POOLING REMIC, the SECOND-TIER REMIC, and the ISSUING
REMIC for purposes of the REMIC Provisions.  The ISSUING REMIC shall hold as its
assets the several classes of uncertificated Lower Tier Interests in the SECOND-
TIER REMIC, other than the Class LT2-R Interest, and each such Lower Tier
Interest is hereby designated as a regular interest in the SECOND-TIER REMIC for
purposes of the REMIC Provisions.  The SECOND-TIER REMIC shall hold as its
assets the several classes of uncertificated Lower Tier Interests in the POOLING
REMIC, other than the Class LT1-R Interest, and each such Lower Tier Interest is
hereby designated as a regular interest in the POOLING REMIC.  The POOLING REMIC
shall hold as its assets the property of the Trust Estate other than the Lower
Tier Interests in the POOLING REMIC and the SECOND-TIER REMIC, the Prefunding
Account, and the Capitalized Interest Account.  The startup day for each REMIC
created hereby for purposes of the REMIC Provisions is the Closing Date.  In
addition, for purposes of the REMIC Provisions, the latest possible maturity
date for each regular interest in each REMIC created hereby is the latest date
specified in Section 9.01 of the Standard Terms.

(1)  The interest rate with respect to any Distribution Date (and the related
     Accrual Period) for these Interests is a per annum rate equal to the
     weighted average of the Net Rates of the Mortgage Loans in Group I as of
     the first day of the calendar month immediately preceding the Distribution
     Date.

  On each Distribution Date, all collections and other recoveries attributable
