    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) 10.2%.

(4) 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.

(5) 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)

    (B) 10.2%.

(7) The Class PT1-R Interest shall not bear interest.

            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 to
the outstanding Pooling-Tier REMIC-1 Regular Interest relating to certificates
with the lowest numerical denomination until the Pooling-Tier REMIC-1 Principal
Amount of such interest or interests, as the case may be, is reduced to zero,
provided that, with respect to Pooling-Tier REMIC-1 Regular Interests relating
to certificates with the same numerical denomination, such Realized Losses and
payments of principal shall be allocated pro rata between such Pooling-Tier
REMIC-1 Regular Interests.

------------
(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) 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 Mortgage Loans shall be allocated to
the outstanding Pooling-Tier REMIC-2 Regular Interests (other than the
Pooling-Tier REMIC-2 IO Interests) with the lowest numerical denomination until
the Pooling-Tier REMIC-2 Principal Amount of such interest or interests, as the
case may be, is reduced to zero, provided that, for Pooling-Tier REMIC-2 Regular
Interests 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.

                                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 Interests).

(2) 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.

(3) 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-M-1, Class LT-M-2, Class LT-M-3, Class LT-M-4, Class LT-M-5, Class
LT-M-6, Class LT-B-1, Class LT-B-2, Class LT-B-3, Class LT-B-4 and Class LT-B-5
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, 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 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 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.

                                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
regular interest in the Upper-Tier REMIC. The Class UT-R Interest is hereby
designated as the sole class of residual interests in the Upper-Tier REMIC and
shall be represented by the Class R Certificates.

(1) 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 WAC Cap) for the Corresponding Class of
    Certificates and (ii) the Upper-Tier REMIC WAC Rate.

(2) 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.

(3) The Class UT-CE Interest has an initial principal balance of $8,928,486 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
    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 Interest) as of the first day of the related Interest
    Accrual Period. With respect to any Interest Accrual Period, the Class UT-CE
    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 Interest), 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 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) 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.

    obligation to make payments of Basis Risk Carry Forward Amounts and, without
    duplication, Upper-Tier Carry Forward Amounts from the Excess Reserve Fund
    Account and the Supplemental Interest Trust as payments made pursuant to an
    interest rate cap contract written by the Class CE Certificateholders in
    favor of each applicable Class of Principal Certificates. Such rights of the
    Class CE 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 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 Lower-Tier Interest and the Class UT-R

present and future Certificateholders.

            The Trustee agrees to execute and deliver (or cause the Custodian to

            The Trustee agrees, for the benefit of the Certificateholders, to

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

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

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 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.


            Section 2.03 Repurchase or Substitution of Mortgage Loans by the
Seller. (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, a Mortgage File or of
the breach by the Seller of any representation, warranty or covenant under the
Mortgage Loan Purchase Agreement or in Section 2.04 in respect of any Mortgage
Loan which materially adversely affects the value of such Mortgage Loan or the
interest therein of the Certificateholders, the Trustee (or the Custodian, as
applicable) shall promptly notify the Seller and the Servicer of such defect,
missing document or breach and request that the Seller deliver such missing
document or cure such defect or breach within 120 days or 150 days following the
Closing Date, in the case of missing Mortgages or Assignments from the date the
Seller was notified of such missing document, defect or breach, and if the
Seller does not deliver such missing document or cure such defect or breach in
all material respects during such period, and such breach or defect materially
and adversely affects the interests of the certificateholders, the Trustee shall
enforce the Seller's obligation under the Mortgage Loan Purchase Agreement and
inform the Seller of its obligation to repurchase such Mortgage Loan from the
Trust Fund at the Repurchase Price on or prior to the Determination Date
following the expiration of such 120 day period (subject to Section 2.03(e));
provided that, in connection with any such breach that could not reasonably have
been cured within such 120 day or 150 day period, if the Seller shall have
commenced to cure such breach within such 120 day or 150 day period, the Seller
shall be permitted to proceed thereafter diligently and expeditiously to cure
the same within the additional period provided under the Mortgage Loan Purchase
Agreement. The Repurchase Price for the repurchased Mortgage Loan shall be
deposited in the Collection Account, and the Trustee, upon receipt of written
certification from the Servicer of such deposit, shall release to the Seller the
related Mortgage File and shall execute and deliver such instruments of transfer
or assignment, in each case without recourse, representation or warranty, as the
Seller shall furnish to it and as shall be necessary to vest in the Seller any
Mortgage Loan released pursuant hereto and the Trustee shall have no further
responsibility with regard to such Mortgage File. In lieu of repurchasing any
such Mortgage Loan as provided above, the Seller may cause such Mortgage Loan to
be removed from the Trust Fund (in which case it shall become a Defective
Mortgage Loan) and substitute one or more Eligible Substitute Mortgage Loans in
the manner and subject to the limitations set forth in Section 2.03(d). It is
understood and agreed that the obligation of the Seller to cure or to repurchase
(or to substitute for) any Mortgage Loan as to which a document is missing, a
material defect in a constituent document exists or as to which such a breach
has occurred and is continuing shall constitute the sole remedy against the
Seller respecting such omission, defect or breach available to the Trustee on
behalf of the Certificateholders.

            (b) [Reserved].

            (c) Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of any representation, warranty
or covenant of the Servicer set forth in Section 2.05 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Servicer shall cure such breach in all material respects.

            (d) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Defective Mortgage Loan for which the Seller substitutes an Eligible
Substitute Mortgage Loan or Loans, such substitution shall be effected by the
Seller delivering to the Trustee, for such Eligible Substitute Mortgage Loan or
Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such
other documents and agreements, with all necessary endorsements thereon, as are
required by Section 2.01(b), together with an Officers' Certificate providing
that each such Eligible Substitute Mortgage Loan satisfies the definition
thereof and specifying the Substitution Adjustment Amount (as described below),
if any, in connection with such substitution. The Trustee shall acknowledge
receipt for such Eligible Substitute Mortgage Loan or Loans and, within ten
Business Days thereafter, shall review such documents as specified in Section
2.02 and deliver (or cause the Custodian to deliver) to the Servicer, with
respect to such Eligible Substitute Mortgage Loan or Loans, a certification
substantially in the form attached hereto as Exhibit F-1, with any applicable
exceptions noted thereon. Within one year of the date of substitution, the
Trustee shall deliver (or cause the custodian to deliver) to the Servicer a
certification substantially in the form of Exhibit F-2 with respect to such
Eligible Substitute Mortgage Loan(s), with any applicable exceptions noted
thereon. Monthly Payments due with respect to Eligible Substitute Mortgage Loans
in the month of substitution are not part of the Trust Fund and will be retained
by the Seller. For the month of substitution, distributions to
Certificateholders will reflect the collections and recoveries in respect of
such Defective Mortgage Loan in the Collection Period preceding the month of
substitution and the Depositor or the Seller, as the case may be, shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Defective Mortgage Loan. The Seller shall give or cause to be given written
notice to the Certificateholders that such substitution has taken place, shall
amend the Mortgage Loan Schedule to reflect the removal of such Defective
Mortgage Loan from the terms of this Agreement and the substitution of the
Eligible Substitute Mortgage Loan or Loans and shall deliver a copy of such
amended Mortgage Loan Schedule to the Trustee and the Custodian. Upon such
substitution, such Eligible Substitute Mortgage Loan or Loans shall constitute
part of the Mortgage Pool and shall be subject in all respects to the terms of
this Agreement and, in the case of a substitution effected by the Seller, the
Mortgage Loan Purchase Agreement, including, in the case of a substitution
