                              W I T N E S S E T H:
                              --------------------

              In consideration of the mutual agreements herein contained, the
parties hereto agree as follows:

                              PRELIMINARY STATEMENT

              The Trustee shall elect that five segregated asset pools within
the Trust Fund (exclusive of (i) the Prepayment Premiums, (ii) the Interest Rate
Swap Agreement, (iii) the Supplemental Interest Trust, (iv) the Excess Reserve
Fund Account, and (v) the right of the LIBOR Certificates to receive Upper-Tier
Carry Forward Amounts and, without duplication, Basis Risk Carry Forward Amounts
and the obligation to pay Class IO Shortfalls) be treated for federal income tax
purposes as comprising five REMICs (each, a "Trust REMIC" or, in the
alternative, Pooling-Tier REMIC-1, Pooling-Tier REMIC-2, the Lower-Tier REMIC,
the Upper-Tier REMIC and the Class X REMIC, respectively). The Class X Interest,
Class IO Interest and each Class of LIBOR Certificates (other than the right of
each Class of LIBOR Certificates to receive (i) Basis Risk Carry Forward Amounts
and, without duplication, Upper-Tier Carry Forward Amounts and (ii) the
obligation to pay Class IO Shortfalls) represents ownership of a regular
interest in a REMIC for purposes of the REMIC Provisions.

              The Class RX Certificates represent ownership of the sole class of
residual interest in the Class X REMIC for purposes of the REMIC Provisions. The
Class RC Certificates represent ownership of the sole class of residual interest
in Pooling-Tier REMIC-1 for purposes of the REMIC Provisions. The Class R
Certificates represent ownership of the sole class of residual interest in each
of Pooling-Tier REMIC-2, the Lower-Tier REMIC and the Upper-Tier REMIC for
purposes of the REMIC Provisions.

              The Start-up Day for each Trust REMIC is the Closing Date. The
latest possible maturity date for each regular interest is the latest date
referenced in Section 2.05.

              The Class X REMIC shall hold as assets the Class UT-X Interest,
the Class UT-IO Interest and the Class UT-3 Interest as set out below. The
Upper-Tier REMIC shall hold as assets the several classes of uncertificated
Lower-Tier Regular Interests, set out below. The Lower-Tier REMIC shall hold as

Interests. Pooling-Tier REMIC-2 shall hold as assets the several classes of
uncertificated Pooling-Tier REMIC-1 Regular Interests. Pooling-Tier REMIC-1
shall hold as assets the assets of the Trust Fund (exclusive of (i) the
Prepayment Premiums, (ii) the Interest Rate Swap Agreement, (iii) the
Supplemental Interest Trust, (iv) the Excess Reserve Fund Account and (v) the
right of the LIBOR Certificates to receive Basis Risk Carry Forward Amounts and,
without duplication, Upper-Tier Carry Forward Amounts and the obligation to pay
Class IO Shortfalls). Each such Lower Tier Regular Interest is hereby designated
as a regular interest in the Lower Tier REMIC. The Class LT-A-1, Class LT-A-2A,
Class LT-A-2B, Class LT-A-2C, Class LT-A-2D, Class LT-M-1, Class LT-M-2, Class
LT-M-3, Class LT-M-4, Class LT-M-5, Class LT-M-6, Class LT-M-7, Class LT-M-8,
Class LT-M-9, Class LT-B-1 and Class LT-B-2 Interests are hereby designated the
LT-Accretion Directed Classes (the "LT-Accretion Directed Classes").

               The Class X REMIC shall hold as assets the Class UT-X Interest,
the Class UT-IO Interest and the Class UT-3 Interest issued by the Upper-Tier
REMIC, the Class X Interest and the Class IO Interest shall represent the
regular interests issued by the Class X REMIC and the Class RX Interest shall
represent the sole class residual interest in the Class X REMIC. The Class X
Certificates shall represent beneficial ownership of the Class X Interest, the
Class IO Interest, the Supplemental Interest Trust and the Excess Reserve Fund
Account.

              For federal income tax purposes, each Class of LIBOR Certificates,
the Class X Certificates and the Class P Certificates represent beneficial
ownership of portions of the Trust Fund which shall be treated as a grantor
trust as more fully described in Section 8.11.

                              Pooling-Tier REMIC-1
                              --------------------

              Pooling-Tier REMIC-1 shall issue the following interests in
Pooling-Tier REMIC-1, and each such interest is hereby designated as a regular
interest in the Pooling-Tier REMIC-1. Pooling-Tier REMIC-1 Interests with an "I"
in their designation shall relate to Loan Group I and Pooling Tier REMIC-1
Interests with a "II" in their designation shall relate to Loan Group II.

(1)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the Pooling-Tier
       REMIC-1 Loan Group I WAC Rate.

(2)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
       average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
       REMIC-1 Regular Interests relating to Loan Group I and having an "A" in
        their class designation, provided that, on each Distribution Date on
       which interest is distributable on the Corresponding Pooling-Tier REMIC-2
       IO Interest, this Pooling-Tier REMIC-2 Regular Interest shall bear
       interest at a per annum rate equal to Swap LIBOR subject to a maximum
       rate equal to the weighted average of the Pooling-Tier REMIC-1 Interest
       Rates on the Pooling-Tier REMIC-1 Regular Interests relating to Loan
       Group I and having an "A" in their class designation.

(3)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
       average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
       REMIC-1 Regular Interests relating to Loan Group I and having a "B" in
       their class designation.

(4)     Each Pooling-Tier REMIC-2 IO is an interest-only interest and does not
       have a principal balance but has a notional balance ("Pooling-Tier
       REMIC-2 IO Notional Balance") equal to the Pooling-Tier REMIC-2 Principal
       Amount of the Corresponding Pooling-Tier REMIC-1 Regular Interest. From
       the Closing Date through and including the Corresponding Actual Crossover
       Distribution Date, each Pooling-Tier REMIC-2 IO Interest shall be
       entitled to receive interest that accrues on the Corresponding
       Pooling-Tier REMIC-1 Regular Interest at a rate equal to the excess, if
       any, of (i) the Pooling-Tier REMIC-1 Interest Rate for the Corresponding
       Pooling-Tier REMIC-1 Regular Interest over (ii) Swap LIBOR. After the
       Corresponding Actual Crossover Distribution Date, the Pooling-Tier
       REMIC-2 IO Interest shall not accrue interest.

(5)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the Pooling-Tier
       REMIC-1 Loan Group II WAC Rate.

(6)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
       average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
       REMIC-1 Regular Interests relating to Loan Group II and having an "A" in
       their class designation, provided that, on each Distribution Date on
       which interest is distributable on the Corresponding Pooling-Tier REMIC-2
       IO Interest, this Pooling-Tier REMIC-2 Regular Interest shall bear
       interest at a per annum rate equal to Swap LIBOR subject to a maximum
       rate equal to the weighted average of the Pooling-Tier REMIC-1 Interest
       Rates on the Pooling-Tier REMIC-1 Regular Interests relating to Loan
       Group II and having an "A" in their class designation.

(7)     For any Distribution Date (and the related Interest Accrual Period), this
       Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
       rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
       average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
       REMIC-1 Regular Interests relating to Loan Group II and having a "B" in
       their class designation.

(8)     The Class PT2-R Interest shall not bear interest.


              On each Distribution Date, the interest distributable in respect
of the Mortgage Loans for such Distribution Date shall be distributed to the
Pooling-Tier REMIC-2 Regular Interests at the Pooling-Tier REMIC-2 Interest
Rates shown above.

              On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Group I Mortgage Loans shall be
allocated to the Class R Certificates in respect of the Class PT2-R Interest
pursuant to Section 4.02(a)(iii) until its Class Certificate Balance is reduced
to zero, then to the outstanding Pooling-Tier REMIC-2 Regular Interests (other
than the Pooling-Tier REMIC-2 IO Interests) relating to Loan Group I with the
lowest numerical denomination until the Pooling-Tier REMIC-2 Principal Amount of
such interest is reduced to zero, provided that, for Pooling-Tier REMIC-2
Regular Interests relating to Loan Group I with the same numerical denomination,
such Realized Losses and payments of principal shall be allocated pro rata
between such Pooling-Tier REMIC-2 Regular Interests, until the Pooling-Tier
REMIC-2 Principal Amount of such interest is reduced to zero.

              On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Group II Mortgage Loans shall be
allocated to the outstanding Pooling-Tier REMIC-2 Regular Interests (other than
the Pooling-Tier REMIC-2 IO Interests) relating to Loan Group II with the lowest
numerical denomination until the Pooling-Tier REMIC-2 Principal Amount of such
interest is reduced to zero, provided that, for Pooling-Tier REMIC-2 Regular
Interests relating to Loan Group II with the same numerical denomination, such
Realized Losses and payments of principal shall be allocated pro rata between
such Pooling-Tier REMIC-2 Regular Interests, until the Pooling-Tier REMIC-2
Principal Amount of such interest is reduced to zero.

                                Lower-Tier REMIC

(1)     The interest rate with respect to any Distribution Date for these
       interests is a per annum variable rate equal to the weighted average of
       the Pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
       Regular Interests (other than the Pooling-Tier REMIC-2 IO Interests).

(2)     The interest rate with respect to any Distribution Date for the Class
       LT-Group I Interest is a per annum variable rate (expressed as a
       percentage rounded to eight decimal places) equal to the weighted average
       of the Pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
       Regular Interests (other than the Pooling Tier REMIC-2 IO Interests)
       relating to Loan Group I.

(3)     The interest rate with respect to any Distribution Date for the Class
       LT-Group II Interest is a per annum variable rate (expressed as a
       percentage rounded to eight decimal places) equal to the weighted average
       of the Pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
       Regular Interests (other than the Pooling Tier REMIC-2 IO Interests)
       relating to Loan Group II.

(4)     For all Distribution Dates, the Lower-Tier Principal Amount of these
       Lower-Tier Regular Interests shall be rounded to eight decimal places.

(5)     This Lower-Tier Regular Interest is an interest-only interest and does
       not have a Lower-Tier Principal Amount. On each Distribution Date, this
       Lower-Tier Regular Interest shall be entitled to receive all interest
        distributable on the Pooling-Tier REMIC-2 IO Interests.

(6)     This Lower-Tier Regular Interest shall not be entitled to interest and
       shall have a Lower-Tier Principal Amount at all times equal to the Class
       Certificate Balance of the Class RX Certificates.

(7)     The Class LT-R Interest does not have a principal amount or an interest
       rate.


              Each Lower-Tier Regular Interest is hereby designated as a regular
interest in the Lower-Tier REMIC. The Class LT-A-1, Class LT-A-2A, Class
LT-A-2B, Class LT-A-2C, Class LT-A-2D, Class LT-M-1, Class LT-M-2, Class LT-M-3,
Class LT-M-4, Class LT-M-5, Class LT-M-6, Class LT-M-7, Class LT-M-8, Class
LT-M-9, Class LT-B-1 and Class LT-B-2 Interests are hereby designated the
LT-Accretion Directed Classes (the "LT-Accretion Directed Classes").

              On each Distribution Date, 50% of the increase in the
Overcollateralized Amount shall be payable as a reduction of the Lower-Tier
Principal Amount of the LT-Accretion Directed Classes (each such Class will be
reduced by an amount equal to 50% of any increase in the Overcollateralized
Amount that is attributable to a reduction in the Class Certificate Balance of
its Corresponding Class) and shall be accrued and added to the Lower-Tier
Principal Amount of the Class LT-Accrual Interest. On each Distribution Date,
the increase in the Lower-Tier Principal Amount of the Class LT-Accrual Interest
shall not exceed interest accruals for such Distribution Date for the Class
LT-Accrual Interest. In the event that: (i) 50% of the increase in the
Overcollateralized Amount exceeds (ii) interest accruals on the Class LT-Accrual
Interest for such Distribution Date, the excess for such Distribution Date
(accumulated with all such excesses for all prior Distribution Dates) will be
added to any increase in the Overcollateralized Amount for purposes of
determining the amount of interest accrual on the Class LT-Accrual Interest
payable as principal on the LT-Accretion Directed Classes on the next
Distribution Date pursuant to the first sentence of this paragraph. All payments
of scheduled principal and prepayments of principal generated by the Mortgage
Loans and all Subsequent Recoveries allocable to principal shall be allocated
(i) 50% to the Class LT-Accrual Interest, the Class LT-Group I Interest and
Class LT-Group II Interest (and further allocated among these Lower-Tier Regular
Interests in the manner described below) and (ii) 50% to the LT-Accretion
Directed Classes (such principal payments and Subsequent Recoveries shall be
allocated among such LT-Accretion Directed Classes in an amount equal to 50% of
the principal amounts and Subsequent Recoveries allocated to their respective
Corresponding Classes), until paid in full. Notwithstanding the above, principal
payments allocated to the Class X Interest that result in the reduction in the
Overcollateralized Amount shall be allocated to the Class LT-Accrual Interest
(until paid in full). Realized Losses shall be applied so that after all
distributions have been made on each Distribution Date (i) the Lower-Tier
Principal Amount of each of the LT-Accretion Directed Classes is equal to 50% of
the Class Certificate Balance of their Corresponding Class, and (ii) the Class
LT-Accrual Interest, the Class LT-Group I and the Class LT-Group II Interest
(and further allocated among these Lower-Tier Regular Interests in the manner
described below) is equal to 50% of the aggregate Stated Principal Balance of
the Mortgage Loans plus 50% of the Overcollateralized Amount. Any increase in
the Class Certificate Balance of a Class of LIBOR Certificates as a result of a
Subsequent Recovery shall increase the Lower-Tier Principal Amount of the
Corresponding Lower-Tier Regular Interest by 50% of such increase, and the
remaining 50% of such increase shall increase the Lower-Tier Principal Amount of
the Class LT-Accrual Interest. As among the Class LT-Accrual Interest, the Class
LT-Group I Interest and the Class LT-Group II Interest, all payments of
scheduled principal and prepayments of principal generated by the Mortgage
Loans, all Subsequent Recoveries and all Realized Losses, allocable to such
Lower-Tier Regular Interests shall be allocated (i) to the Class LT-Group I
Interest and the Class LT-Group II Interest, each from the related Loan Group so
that their respective Lower-Tier Principal Amounts (computed to at least eight
decimal places) are equal to 0.001% of the aggregate Stated Principal Balance of
the Mortgage Loans in the related Loan Group and (ii) the remainder to the Class
LT-Accrual Interest.


                                Upper-Tier REMIC

              The Upper-Tier REMIC shall issue the following interests, and each
such interest, other than the Class UT-R Interest, is hereby designated as a

-----------------

(1)     For any Distribution Date (and the related Interest Accrual Period), this
       interest shall bear interest at the least of (i) the Pass-Through Rate
       (determined without regard to the Loan Group I Cap or WAC Cap) for the
       Corresponding Class of Certificates, (ii) the Lower-Tier Interest Rate
       for the Class LT-Group I Interest (the "Upper-Tier REMIC Loan Group I
       Rate") and (iii) the Upper-Tier REMIC WAC Rate.

(2)     For any Distribution Date (and the related Interest Accrual Period), this
       interest shall bear interest at the least of (i) the Pass-Through Rate
       (determined without regard to the Loan Group II Cap or WAC Cap) for the
       Corresponding Class of Certificates, (ii) the Lower-Tier Interest Rate
       for the Class LT-Group II Interest (the "Upper-Tier REMIC Loan Group II
       Rate") and (iii) the Upper-Tier REMIC WAC Rate.

(3)     For any Distribution Date (and the related Interest Accrual Period), this
       interest shall bear interest at the lesser of (i) the Pass-Through Rate
       (determined without regard to the applicable WAC Cap) for the
       Corresponding Class of Certificates and (ii) the Upper-Tier REMIC WAC
        Rate.

(4)     This interest is an interest-only interest and does not have a principal
       balance. On each Distribution Date, the Class UT-IO Interest shall be
       entitled to receive all interest distributable on the Class LT-IO
       Interest.

(5)     The Class UT-X Interest has an initial principal balance of $33,946,197
       but will not accrue interest on such balance but will accrue interest on
       a notional principal balance. As of any Distribution Date, the Class UT-X
       Interest shall have a notional principal balance equal to the aggregate
       of the Lower-Tier Principal Amounts of the Lower-Tier Regular Interests
       (other than the Class LT-IO and Class LT-3 Interests) as of the first day
       of the related Interest Accrual Period. With respect to any Interest
       Accrual Period, the Class UT-X Interest shall bear interest at a rate
       equal to the excess, if any, of the Upper-Tier REMIC WAC Rate over the
       product of (i) 2 and (ii) the weighted average of the Lower-Tier Interest
       Rates of the Lower-Tier REMIC Interests (other than the Class LT-IO and
       Class LT-3 Interests), where the Lower-Tier Interest Rate on each of the
       Class LT-Accrual Interest, Class LT-Group I Interest and Class LT-Group
       II Interest is subject to a cap equal to zero and each LT-Accretion
       Directed Class is subject to a cap equal to the Upper-Tier Interest Rate
       on its Corresponding Class of Upper-Tier Regular Interest. With respect
       to any Distribution Date, interest that so accrues on the notional
       principal balance of the Class UT-X Interest shall be deferred in an
       amount equal to any increase in the Overcollateralized Amount on such
       Distribution Date. Such deferred interest shall not itself bear interest.

(6)     This Upper-Tier Regular Interest shall not be entitled to interest and
       shall have a principal balance equal to the Class Certificate Balance of
       the Class RX Certificates.

(7)     The Class UT-R Interest does not have an interest rate or a principal
       balance.

              On each Distribution Date, interest distributable in respect of
the Lower-Tier Interests for such Distribution Date shall be deemed to be
distributed on the interests in the Upper-Tier REMIC at the rates shown above,
provided that the Class UT-IO Interest shall be entitled to receive interest
before any other interest in the Upper-Tier REMIC.


              On each Distribution Date, all Realized Losses, Subsequent
Recoveries and all payments of principal shall be allocated to the Upper-Tier
Interests until the outstanding principal balance of each such interest equals
the outstanding Class Certificate Balance of the Corresponding Class of
Certificates as of such Distribution Date.

                                  Class X REMIC

              The Class X REMIC shall issue the following classes of interests.
The Class X Interest and the Class IO Interest shall each represent a regular
interest in the Class X REMIC and the Class RX Certificates shall represent the
sole class of residual interest in the Class X REMIC.

--------------------------------------------------------------------------------

(1)     The Class X Interest has an initial principal balance equal to the
       initial principal balance of the Class UT-X Interest and is entitled to
       100% of the interest and principal on the Class UT-X Interest on each
       Distribution Date.

(2)     This interest is an interest-only interest and does not have a principal
       balance. On each Distribution Date the Class IO Interest shall be
       entitled to receive 100% of the interest distributable on the Class UT-IO
       Interest.

(3)     The Class RX Certificates do not have an interest rate.

       Interest Trust. Each of these Certificates will also be subject to the
       obligation to pay Class IO Shortfalls as described in Section 8.13. For
       federal income tax purposes, any amount distributed on the LIBOR
       Certificates on any such Distribution Date in excess of the amount
       distributable on the regular interest in the Upper-Tier REMIC on such

       Certificates on such Distribution Date shall be treated as having been

       Certificateholders.

               The minimum denomination for the LIBOR Certificates will be
$25,000, with integral multiples of $1 in excess thereof except that one
