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

(2)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-1 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-1 Interest Rate") equal to the product of
      (i) 2 and (ii) the Pooling-Tier REMIC-1 WAC Rate, subject to a maximum
      rate of 10.20%.

(3)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-1 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-1 Interest Rate") equal to the excess, if
      any, of (A) the product of (i) 2 and (ii) the Pooling-Tier REMIC-1 WAC
      Rate over (B) 10.20%.

(4)    This Pooling-Tier REMIC-1 Regular Interest is an interest-only interest
       and does not have a Pooling-Tier REMIC-1 Principal Amount. On each
      Distribution Date, this Pooling-Tier REMIC-1 Regular Interest shall be
      entitled to receive interest equal to the Excess Servicing Fee.

(5)    The Class PT1-R Interest shall not bear interest or have a principal
      balance.

            On each Distribution Date, the Trustee shall first pay from the
Trust Fund and charge as an expense of Pooling-Tier REMIC-1 all expenses of the
Trust for such Distribution Date. Such expense, other than Servicing Fees, the
Custodian Fees and Trustee Fees, shall be allocated in the same manner as
Realized Losses.

            On each Distribution Date, the interest distributable in respect of
the Mortgage Loans for such Distribution Date shall be deemed to be distributed
to the Pooling-Tier REMIC-1 Regular Interests at the rates shown above.

            On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Mortgage Loans shall be allocated
sequentially to the outstanding Pooling-Tier REMIC-1 Regular Interest with the
lowest numerical designation (other than the Class PT1-1 and Class PT1-CE2
Interests) such that, at all times, the aggregate Pooling-Tier Principal Amount
of such Pooling-Tier REMIC-1 Regular Interests equals the aggregate Class
Certificate Balance of the then outstanding LIBOR Certificates, and otherwise to
Class PT1-1 Interest until the Pooling-Tier REMIC-1 Principal Amount of each
such interest is reduced to zero; provided that, with respect to Pooling-Tier
REMIC-1 Regular Interests relating to certificates with the same numerical
designation, such Realized Losses, Subsequent Recoveries and payments of
principal shall be allocated pro rata between such Pooling-Tier REMIC-1 Regular
Interests.

                              Pooling-Tier REMIC-2

            Pooling-Tier REMIC-2 shall issue the following interests in
Pooling-Tier REMIC-2, and each such interest, other than the Class PT2-R
Interest, is hereby designated as a regular interest in Pooling-Tier REMIC-2.
The Class PT2-R Interest is hereby designated as the sole class of residual
interest in Pooling-Tier REMIC-2 and shall be represented by the Class R
Certificates.

(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 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 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 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 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 Scheduled 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
      Scheduled Crossover Distribution Date, the Pooling-Tier REMIC-2 IO
       Interest shall not accrue interest.

(5)    This Pooling-Tier REMIC-2 Regular Interest is an interest-only interest
      and does not have a Pooling-Tier REMIC-2 Principal Amount. On each
      Distribution Date, this Pooling-Tier REMIC-2 Regular Interest shall be
      entitled to receive all interest distributable on the Class PT1-CE2
      Interest.

(6)    The Class PT2-R Interest shall not have a principal balance and 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 Mortgage Loans shall be allocated
sequentially to the outstanding Pooling-Tier REMIC-2 Regular Interests (other
than the Pooling-Tier REMIC-2 IO and Class PT2-CE2 Interests) with the lowest
numerical designation (other than the Class PT2-1 Interest) such that, at all
times, the aggregate Pooling-Tier Principal Amount of such Pooling-Tier REMIC-2
Regular Interests equals the aggregate Class Certificate Balance of the then
outstanding LIBOR Certificates and finally to the Class PT2-1 Interest until the
Pooling-Tier REMIC-2 Principal Amount of each such interest is reduced to zero;
provided that, for Pooling-Tier REMIC-2 Regular Interests with the same
numerical designation, such Realized Losses, Subsequent Recoveries and payments
of principal shall be allocated pro rata between such Pooling-Tier REMIC-2
Regular Interests.

                                Lower-Tier REMIC

            The Lower-Tier REMIC shall issue the following interests, and each
such interest, other than the Class LT-R Interest, is hereby designated as a
regular interest in the Lower-Tier REMIC. The Class LT-R Interest is hereby
designated as the sole class of residual interest in the Lower-Tier REMIC and
shall be represented by the Class R Certificates.

(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 and Class PT-CE2
      Interests).

(2)    The interest rate with respect to any Distribution Date for the Class
       LT-FL 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 Class PT2-1 and Class PT2-CE2 Interests and the
      Pooling-Tier REMIC-2 IO Interests).

(3)    The interest rate with respect to any Distribution Date for the Class
      LT-FX Interest is a per annum variable rate (expressed as a percentage
      rounded to eight decimal places) equal to the Pooling-Tier REMIC-2
      Interest Rate of the Class PT2-1 Interest.

(4)    For all Distribution Dates, the Lower-Tier Principal Amount of this
      Lower-Tier Regular Interest 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 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 Class PT2-CE2 Interest.

(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-2, Class LT-A-3,
Class LT-A-4, 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,
Class LT-B-2 and Class LT-B-3 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, Class LT-FL Interest and Class LT-FX
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 CE-1 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, Class
LT-FL Interest and Class LT-FX 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 Principal 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, Class LT-FL Interest and the Class LT-FX
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-FL Interest so that its Lower-Tier Principal Amount (computed to at
least eight decimal places) is equal to 0.001% aggregate Class Certificate
Balance of Floating Rate Certificates, (ii) to the Class LT-FX Interest so that
its Lower-Tier Principal Amount (computed to at least eight decimal places) is
equal to 0.001% of the aggregate Stated Principal Balance of Mortgage Loans
minus the aggregate Class Certificate Balance of Floating Rate Certificates and
(iii) the remainder to the Class LT-Accrual Interest.

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the Pass-Through Rate for the
      Corresponding Class of Certificates (without reduction in the WAC Cap, in
      the case of the LIBOR Certificates, for Swap Termination Payments).

(2)    This Upper-Tier Regular Interest is an interest-only interest and does not
      have an Upper-Tier Principal Amount. On each Distribution Date, the Class
      UT-IO Interest shall be entitled to receive all interest distributable on
      the Class LT-IO Interest.

(3)    The Class UT-CE-1 Interest has an initial principal balance of $13,376,172
      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-CE-1
      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, Class LT-CE2, Class LT-FL and Class LT-FX
      Interests) as of the first day of the related Interest Accrual Period.
      With respect to any Interest Accrual Period, the Class UT-CE-1 Interest
      shall bear interest at a rate equal to the excess, if any, of the
      Lower-Tier Interest Rate for the Class LT-Accrual Interest 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, Class
      LT-CE2, Class LT-FL and Class LT-FX Interests), where the Lower-Tier
      Interest Rate on the Class LT-Accrual 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-CE-1 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.

(4)    This Upper-Tier Regular Interest is an interest-only interest and does not
      have an Upper-Tier Principal Amount. On each Distribution Date, this
      Upper-Tier Regular Interest shall be entitled to receive all interest
      distributable on the Class LT-CE2 Interest.

(5)    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.

(1)    Interest will accrue during each Interest Accrual Period at a per annum
      rate equal to the least of (1) One-Month LIBOR plus the applicable
      Pass-Through Margin, (2) the WAC Cap and (3) the Maximum Rate Cap.

(2)    Interest will accrue during each Interest Accrual Period at a per annum
      rate equal to the least of (1) the applicable Fixed Rate, (2) the WAC Cap
      and (3) the Maximum Rate Cap.

(3)    Each of these Certificates will represent not only the ownership of a
      regular interest in the Corresponding REMIC but also the right to receive
      payments from the Excess Reserve Fund Account and in the case of the LIBOR
      Certificates, the Supplemental 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 Principal Certificates on any such Distribution Date in
      excess of the amount distributable on the regular interest in the
      Corresponding REMIC on such Distribution Date shall be treated as having
      been paid from the Excess Reserve Fund Account or the Supplemental
      Interest Trust, as applicable, and any amount distributable on such
      regular interest on such Distribution Date in excess of the amount
      distributable on the Principal Certificates on such Distribution Date
      shall be treated as having been paid to the Supplemental Interest Trust,
      all pursuant to, and as further provided in, Section 8.13. The Trustee
      will treat a Principal Certificateholder's right to receive payments from
      the Excess Reserve Fund Account and in the case of the LIBOR Certificates,
      the Supplemental Interest Trust, subject to the obligation to pay Class IO
      Shortfalls, as payments made pursuant to a notional principal contract

      Class CE-1 Interest, (ii) the Class IO Interest, (iii) the right to
      receive Class IO Shortfalls, (iv) the Interest Rate Cap Agreement, (v)
      amounts in the Supplemental Interest Trust, including the Interest Rate
      Swap Agreement subject to the obligation to pay Net Swap Payments, to pay
      the LIBOR Certificates their respective Basis Risk Carry Forward Amounts
      and (vi) amounts in the Excess Reserve Fund Account, subject to the
      obligation to make payments from the Excess Reserve Fund Account to the
      Principal Certificates in respect of Basis Risk Carry Forward Amounts. For
      federal income tax purposes, the Trustee will treat a Class CE-1
      Certificateholder's obligation to make payments of Basis Risk Carry
      Forward Amounts to the Principal Certificates from the Excess Reserve Fund
      Account and, without duplication, to the LIBOR Certificates from the
      Supplemental Interest Trust and the right to receive Class IO Shortfalls
      as payments made pursuant to a notional principal contract between the
      Class CE-1 Certificateholders and each applicable Class of Principal
      Certificates. Such rights of the Class CE-1 Certificateholders and
       Principal Certificateholders shall be treated as held in a portion of the
      Trust Fund that is treated as a grantor trust under subpart E, Part I of
      subchapter J of the Code.

(5)    The Class CE2 Certificates represent ownership of the Class CE2 Interest.

(6)    The Class R Certificates do not have an interest rate. The Class R
      Certificates represent ownership of the Class PT1-R Interest, the Class
      PT2-R Interest, the Class LT-R Interest and the Class UT-R Interest.

(7)    The Class R-X Certificates do not have a principal balance or an interest
      rate. The Class R-X Certificates represent the residual interest in the
      Class B-1 REMIC, Class B-2 REMIC, Class B-3 REMIC, Class CE-1 REMIC and
      Class CE-2 REMIC.

             The minimum denomination for the Class A Certificates, will be
$25,000 with integral multiples of $1 in excess thereof and the minimum
denomination for the Class M and Class B Certificates, will be $25,000, except
that one Certificate in each Class may be issued in a different amount. The
minimum denomination for each of the Class P, Class CE-1 and Class CE-2
Certificates will be a 1% Percentage Interest in such Class, the minimum
denomination for the Class R Certificates will be $50, and the minimum
denomination for the Class R-X Certificates shall be 100% Percentage Interest in
such Class.

            It is expected that each Class of Certificates will receive its
final distribution on or prior to the applicable Final Scheduled Distribution

            Section 2.02 Acceptance by the Trustee of the Mortgage Loans. The
Trustee acknowledges the receipt by the Custodian on its behalf, subject to the
provisions of Section 2.01 and subject to the review described below and any
exceptions noted on the exception report described in the next paragraph below,
the documents referred to in Section 2.01 above and all other assets included in
the definition of "Trust Fund" and declares that the Custodian on behalf of the
Trust Fund holds and will hold such documents and the other documents delivered
to it constituting a Mortgage File pursuant to the Custodial Agreement, and that
the Custodian on behalf of the Trust Fund holds or will hold all such assets and
such other assets included in the definition of "Trust Fund" in trust for the
exclusive use and benefit of all present and future Certificateholders.

            The Trustee agrees to cause the Custodian to execute and deliver to
the Depositor on or prior to the Closing Date an acknowledgment of receipt of
the original Mortgage Note (with any exceptions noted), substantially in the
form attached as Exhibit E hereto.

             The Trustee agrees, for the benefit of the Certificateholders, to
cause the Custodian to review each Mortgage File within 60 days after the
Closing Date (or, with respect to any document delivered after the Startup Day,
within 60 days of receipt and with respect to any Qualified Substitute Mortgage,
within 60 days after the assignment thereof) and to certify (or cause the
Custodian to certify) in substantially the form attached hereto as Exhibit F-1
that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than
any Mortgage Loan paid in full or any Mortgage Loan specifically identified in
the exception report annexed thereto as not being covered by such
certification), (i) all documents required to be delivered to it pursuant to
Section 2.01 of this Agreement are in its possession, (ii) such documents have
been reviewed by it and have not been mutilated, damaged or torn and relate to
such Mortgage Loan, (iii) based on its examination and only as to the foregoing,
the information set forth in the Data Tape Information that corresponds to items
(1), (2), (3), (9), (31) and (33) (but only as to whether the Mortgage Loan has
a Prepayment Charge) of the Mortgage Loan Schedule accurately reflects
information set forth in the Mortgage File, (iv) all Assignments of Mortgage or
intervening assignments of mortgage, as applicable, have been submitted for
recording and (v) each Mortgage Note has been endorsed as provided in Section
2.01(a)(i) of this Agreement and each Mortgage has been assigned in accordance
with Section 2.01(a)(iii) of this Agreement. It is herein acknowledged that, in
conducting such review, the Trustee (or the Custodian, as applicable) is under
no duty or obligation to inspect, review or examine any such documents,
instruments, certificates or other papers to determine that they are genuine,
enforceable, or appropriate for the represented purpose or that they have
actually been recorded or that they are other than what they purport to be on
their face.

            Prior to the first anniversary date of this Agreement the Trustee
shall deliver (or cause the Custodian to deliver) to the Depositor and the
Servicer a final certification in the form annexed hereto as Exhibit F-2
evidencing the completeness of the Mortgage Files, with any applicable
exceptions noted thereon.

            If in the process of reviewing the Mortgage Files and making or
preparing, as the case may be, the certifications referred to above, the Trustee
(or the Custodian, as applicable) finds any document or documents constituting a
part of a Mortgage File to be missing or defective in any material respect, at
the conclusion of its review the Trustee, upon its notification by the
Custodian, if applicable, shall so notify the Seller, the Depositor and the
Servicer. In addition, upon the discovery by the Seller, Depositor, the Trustee
or the Servicer (or upon receipt by the Trustee of written notification of such
breach) of a breach of any of the representations and warranties made by the
Seller, in the related Seller Mortgage Loan Purchase Agreement, in respect of
any Mortgage Loan which materially adversely affects such Mortgage Loan or the
interests of the related Certificateholders in such Mortgage Loan, the party
discovering such breach shall give prompt written notice to the other parties.

            The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans and the
Related Documents, conveying good title thereto free and clear of any liens and
encumbrances, from the Depositor to the Trustee and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee, on behalf
of the Trust, a first priority perfected security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and the
Related Documents, and that this Agreement shall constitute a security agreement
under applicable law.
