                                 TRUST AGREEMENT

         THIS TRUST AGREEMENT dated as of December 1, 2000 (this "Agreement"),
among SAXON ASSET SECURITIES COMPANY, a Virginia corporation (the "Depositor"),
SAXON MORTGAGE, INC., a Virginia corporation, as Master Servicer (the "Master
Servicer"), and BANKERS TRUST COMPANY, a New York corporation, as Trustee, under
this Agreement and the Standard Terms to Trust Agreement (February 2000 Edition)
(the "Standard Terms"), all the provisions of which, unless otherwise specified
herein, are incorporated herein and shall be a part of this Agreement as if set
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
$460,000,100 to be known as the Saxon Asset Securities Trust 2000-4, Mortgage
Loan Asset Backed Certificates, Series 2000-4 (the "Certificates"). The
Certificates in the 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 AV-1, Class MV-1, Class MV-2, Class BV-1, 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, the Capitalized Interest Account, the Cap Agreement and the Group II
Reserve Fund. 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 Distribution Date in January 2033.

(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.

(2)      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
         II as of the first day of the calendar month immediately preceding the
         Distribution Date, provided however, that for the first Distribution
         Date (and the related Accrual Period) the interest rate shall be the
         product of (a) the weighted average of the Net Rates of the Mortgage
         Loans in Group II as of the Cut-Off Date and (b) a fraction, the
         numerator of which is the actual number of days in the first Accrual
         Period and the denominator of which is 30.

                                       2

(3)      The Class LT1-R Interest is the sole class of residual interest in the
         POOLING REMIC. It does not have an interest rate or a principal
         balance.


         On each Distribution Date, interest is payable on each POOLING REMIC
Lower Tier Regular Interest at the rate shown above.

         On each Distribution Date, all collections and other recoveries
attributable to principal of the Mortgage Loans in Group I, and all Realized
Losses attributable to the Mortgage Loans in Group I, shall be allocated first
to the Class LT1F-1 Interest until its principal balance is reduced to zero, and
then to each of the remaining Lower Tier Interests in the POOLING REMIC having a
Class LT1F designation sequentially, in ascending numerical order, until the
principal balance of each such Lower Tier Interest is reduced to zero.

         On each Distribution Date, all collections and other recoveries
attributable to principal of the Mortgage Loans in Group II, and all Realized
Losses attributable to the Mortgage Loans in Group II, shall be allocated first
to the Class LT1V-1 Interest until its principal balance is reduced to zero, and
then to each of the remaining Lower Tier Interests in the POOLING REMIC having a
Class LT1V designation sequentially, in ascending numerical order, until the
principal balance of each such Lower Tier Interest is reduced to zero.

         For any Distribution Date, prepayment penalties received with respect
to the Mortgage Loans in Group I and Group II shall be allocated proportionally
among the Lower Tier Interests in the POOLING REMIC in accordance with their
relative principal balances immediately before such Distribution Date.

interest rate, and principal amount for each class of the SECOND-TIER REMIC

respective meanings assigned to them in Section 1.01 of the Standard Terms. In
addition, the following provisions shall govern the defined terms set forth
below for the Trust Agreement. If a term defined in the Standard Terms is also
defined herein, the definition herein shall control.

         "ACCRUAL PERIOD": With respect to the Group I Certificates and the
Class A-IO Certificates and each Lower Tier Interest and any Distribution Date,
the calendar month immediately preceding such Distribution Date; a "calendar
month" shall be deemed to be 30 days. With respect to the Group II Certificates
and any Distribution Date, the period commencing on the immediately preceding
Distribution Date (or in the case of the first Distribution Date, the Closing
Date) and ending on the day immediately preceding the current Distribution Date.
All calculations of interest on the Group I Certificates and the Class A-IO
Certificates will be made on the basis of a 360-day year assumed to consist of
twelve 30-day months and all calculations of interest on the Group II
Certificates will be made on the basis of the actual number of days elapsed in
the related Accrual Period and a year of 360 days.

         "ADJUSTED GROUP I NET RATE": For any Distribution Date (and the related
Accrual Period), the weighted average of the interest rates on the Class LT2-D,
Class LT2-AF-1, Class LT2-AF-2, Class LT2-AF-3, Class LT2-AF-4, Class LT2-AF-5,
Class LT2-AF-6, Class LT2-MF-1, Class LT2-MF-2 and Class LT2-BF-1 Interests
computed for this purpose by limiting the interest rate payable on the Class
LT2-D Interest at zero and the rate payable on each of the other above-listed
Lower Tier Interests in the SECOND-TIER REMIC to a rate that corresponds to the
rate payable for such Distribution Date on the Corresponding Class of
Certificates.

         "A-IO-I ADJUSTED RATE": As of any Distribution Date, the per annum rate
equal to the product of the Class A-IO Pass Through Rate and a fraction, the
numerator of which is the Class A-IO-I Component Notional Principal Balance for
such Distribution Date, and the denominator of which is the Assumed Principal
Balance of the Mortgage Loans in Group I (before giving effect to any
distributions on such Distribution Date).

         "A-IO-II ADJUSTED RATE": As of any Distribution Date, the per annum
rate equal to the product of the Class A-IO Pass Through Rate and a fraction,
the numerator of which is the Class A-IO-II Component Notional Principal Balance
for such Distribution Date, and the denominator of which is the Assumed
Principal Balance of the Mortgage Loans in Group II (before giving effect to any

                  (ii)     any other necessary matters in connection with the
                           administration of the Pre-Funding Account and the
                           Capitalized Interest Account. With respect to each
                           Subsequent Sales Date, the Master Servicer shall
                           determine the Overfunded Interest Amount. If any
                           amounts are released as a result of an error in
                           calculation to the Holders or the Depositor from the
                           Pre-Funding Account or from the Capitalized Interest
                           Account, the Depositor shall immediately repay such
                           amounts to the Master Servicer.

         (a)      The Trustee shall establish and maintain the Pre-Funding
Account and the Capitalized Interest Account, each to be held in trust for the
benefit of the Certificateholders. Each of the Pre-Funding Account and the
Capitalized Interest Account shall be an Eligible Account. On the Closing Date,
the Depositor will cause to be deposited in the Pre-Funding Account the Original
Pre-Funded Amount and in the Capitalized Interest Account the Initial
Capitalized Interest Amount.

         (b)      On any Subsequent Sales Date, the Master Servicer shall
instruct the Trustee, with a copy to the Depositor,

                  (i)      to withdraw from the Pre-Funded Amount in the
                           Pre-Funding Account an amount equal to 100% of the
                           aggregate Scheduled Principal Balances of the
                           Subsequent Mortgage Loans as of the applicable
                           Subsequent Cut-Off Date sold to the Trust on such
                           Subsequent Sales Date and

                  (ii)     to pay such amounts to or upon the order of the
                           Depositor upon satisfaction of the conditions set
                           forth in Section 2.02(c) hereof with respect thereto.
                           In no event shall the Trustee withdraw from the
                           Pre-Funding Account an amount in excess of the
                           Original Pre-Funded Amount.

         (c)      On each Master Servicer Remittance Date to and including the
Master Servicer Remittance Date immediately following the end of the Funding
Period, the Master Servicer shall instruct the Paying Agent to transfer: (i) to
the Capitalized Interest Account from the Pre-Funding Account, the Pre-Funding
Account Earnings; and (ii) to the Asset Proceeds Account from the Capitalized
Interest Account, the Capitalized Interest Requirement.

         (d)      On each Subsequent Sales Date the Master Servicer shall
instruct the Trustee to distribute the Overfunded Interest Amount, if any, to
the Depositor. At the end of the Funding Period, all amounts, if any, remaining
in the Capitalized Interest Account shall be transferred to the Depositor and
the Capitalized Interest Account shall be closed.

         (e)      On the Master Servicer Remittance Date immediately following
the end of the Funding Period, the Master Servicer shall instruct the Trustee to
transfer the Pre-Funded Amount to the Asset Proceeds Account for distribution to
the Holders of the Certificates in accordance with Section 3.01(b) hereof.

         (f)      The Pre-Funding Account and the Capitalized Interest Account
shall not be assets of any REMIC created pursuant to this Agreement.


         SECTION 2.04.  GROUP II RESERVE FUND

         (a)      The depositor hereby directs the Trustee to execute and
deliver, on behalf of the Trust, the Cap Agreement and authorizes the Trustee to
perform its obligations thereunder on behalf of the Trust in accordance with the
terms of the Cap Agreement. On the Closing Date, the Trustee shall enter into
the Cap Agreement, on behalf of the Trust, with the Cap Provider and establish
and maintain in its name, in trust for the benefit of the holders of the Group
II Certificates, the Group II Reserve Fund. The Group II Reserve Fund shall be
an Eligible Account, and funds on deposit therein shall be held separate and
apart from, and shall not be commingled with, any other moneys, including
without limitation, other moneys held by the Trustee pursuant to this Agreement.
The Group II Reserve Fund shall be treated as an "outside reserve fund" under
applicable Treasury regulations and will not be part of any REMIC created
hereunder. For tax purposes, any investment earnings on the Group II Reserve
Fund will be treated as owned by the Master Servicer and will be taxable to the
Master Servicer. For tax purposes, distributions made to any outside reserve
fund under this document shall be treated as made to the owner of such fund.

         (b)      Funds on deposit in the Group II Reserve Fund shall be
invested in Permitted Investments. Any earnings on such amounts shall be for the
benefit of the Group II Certificateholders, and shall remain on deposit in the
Group II Reserve Fund for distribution pursuant to Section 3.03(i). The Master
Servicer shall be deemed the owner of the Group II Reserve Fund for federal tax
purposes only and shall direct the Trustee in writing as to the investment of
amounts on deposit therein.

         (c)      On each Distribution Date, the Trustee shall deposit into the
Group II Reserve Fund from amounts received in respect of the Cap Agreement an
amount equal to the product of (i) the excess, if any, of LIBOR over 6.97%, (ii)
the lesser of (A) the Scheduled Notional Amount and (B) the aggregate
certificate principal balance of the Group II Certificates and (iii) a fraction,
the numerator of which is the actual number of days elapsed from the previous
Distribution Date to but excluding the current Distribution Date (or, for the
first Distribution Date, the actual number of days elapsed from the Closing Date
to but excluding the first Distribution Date), and the denominator of which is
360. One each Distribution Date, the Trustee shall distribute any amounts
received on such Distribution Date in respect of the Cap Agreement in excess of
the amount described in the immediately preceding sentence directly to the
Master Servicer.

                                       49
<PAGE>

         (d)      On each Distribution Date the Trustee shall distribute amounts
on deposit in the Group II Reserve Fund in accordance with Section 3.03(i) of
this Agreement.

         (e)      On the Group II Reserve Fund Release Date, the Trustee shall
distribute amounts remaining on deposit in the Group II Reserve Fund to the
Master Servicer.

         (f)      Each holder of the Group II Certificates, by its acceptance of
the related Group II Certificate, acknowledges and agrees that it has no present
interest in the Group II Reserve Fund and the amounts on deposit or to be
deposited therein, but shall have only a contingent interest in related amounts
distributable on the Group II Certificates as provided in this Agreement. The
Depositor, the Seller and each Residual Certificateholder, by its acceptance of
the Class R Certificate, acknowledges and agrees that it has no interest in the
Group II Reserve Fund and the amounts on deposit or to be deposited therein.

to enter into a facility with any Person which provides that such Person (an
"Advancing Servicer") may make all or a portion of the Advances to the Trust
Fund under this Agreement, although no such facility shall reduce or otherwise
affect the Servicer's obligations to fund such Advances. To the extent that an
Advancing Servicer makes all or a portion of any Advance and provides the
Trustee with notice acknowledged by the Servicer that such Advancing Servicer is
entitled to reimbursement, such Advancing Servicer shall be entitled to receive
reimbursement pursuant to this Agreement for such amount to the extent provided
in Section 3.06(b). Such notice from the Advancing Servicer must specify the
amount of the reimbursement and must specify which Section of this Agreement
permits the Advance to be reimbursed. The Trustee shall be entitled to rely
without independent investigation on the Advancing Servicer's statement with
respect to the amount of any reimbursement pursuant to this Section 3.06 and
with respect to the Advancing Servicer's statement with respect to the Section
of this Agreement permits the Advance to be reimbursed. An Advancing Servicer
whose obligations are limited to the making will not be deemed to be a
Sub-Servicer under this Agreement.

         (b)      If an advancing facility is entered into, then the Servicer
shall not be permitted to reimburse itself therefor under Section 3.01(c) of the
Standard Terms prior to the remittance to the Trust Fund, but instead the

made pursuant to Section 3.02(a) of the Standard Terms. The Trustee is hereby
authorized to pay to the Advancing Servicer, reimbursements for Advances from
the Asset Proceeds Account to the same extent (except as provided below) the
Servicer would have been permitted to reimburse itself for such Advances in
accordance with Section 3.01(c) of the Standard Terms had the Servicer itself

                                       58

funded such Advance. An Advancing Servicer is NOT entitled to be reimbursed by
the Trustee from the Asset Proceeds Account for any reimbursed Advances from
funds held in the Asset Proceeds Account for future distribution pursuant to
Section 3.04 of the Standard Terms. The Trustee is hereby authorized to pay
directly to the Advancing Servicer such portion of the Servicing Fee as the
parties to any advancing facility agree.

         (c)      All Advances made pursuant to the terms of this Agreement
shall be deemed made and shall be reimbursed on a "first-in-first out" (FIFO)
basis; except to the extent that the Trustee is acting as Successor Servicer its
Advances shall be reimbursed first.
