which in turn will hold the Swap Agreement. The SWAP REMIC will consist of all
of the assets constituting the Trust Fund (other than the assets described in
clauses (ii), (iii), (iv) and (v) above, other than the SWAP REMIC Regular
Interests and other than the Lower Tier REMIC Regular Interests) and will be
evidenced by the SWAP REMIC Regular Interests (which will be uncertificated and

Lower Tier REMIC Regular Interests (which will be uncertificated and will
represent the "regular interests" in the Lower Tier REMIC) and the Class LTR
Interest as the single "residual interest" in the Lower Tier REMIC. The Trustee
will hold the Lower Tier REMIC Regular Interests. The Upper Tier REMIC will
consist of the Lower Tier REMIC Regular Interests and will be evidenced by the
REMIC Regular Interests (which will represent the "regular interests" in the
Upper Tier REMIC) and the Residual Interest as the single "residual interest" in
the Upper Tier REMIC. The Class R Certificate will represent beneficial
ownership of the Class SWR Interest, the Class LTR Interest and the Residual
Interest. The "latest possible maturity date" for federal income tax purposes of
all interests created hereby will be the Latest Possible Maturity Date.

     All covenants and agreements made by the Sponsor in the Sale Agreement and

(1)  The initial principal balance of each of these Lower Tier REMIC Regular
     Interests shall equal 1/4 of the initial Certificate Principal Balance of
     its Corresponding Certificates.

(2)  The initial principal balance of the Class LTIX Interest shall equal the
     excess of (i) 50% of the aggregate Cut-off Date Principal Balance of the
     Mortgage Loans over (ii) the initial principal balance of the Lower Tier
     REMIC I Marker Interests.

(3)  The initial principal balance of the Class LTII1A Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of

(8)  For each Distribution Date, the interest rate for each of the Lower Tier
     REMIC Regular Interests (other than the Class LTII1B, the Class LTII2B and
     the Class LT-IO Interests) shall be a per annum rate (but not less than
     zero) equal to the product of (i) the weighted average of the interest
     rates on the SWAP REMIC Regular Interests for such Distribution Date and
     (ii) a fraction the numerator of which is 30 and the denominator of which
     is the actual number of days in the Accrual Period for the LIBOR
     Certificates, provided however, that for any Distribution Date on which the
     Class LT-IO Interest is entitled to a portion of interest accruals on a
     SWAP REMIC Regular Interest ending with a designation "A" as described in
     footnote 11 below, such weighted average shall be computed by first
     subjecting the rate on such SWAP REMIC Regular Interest to a cap equal to
     Swap LIBOR for such Distribution Date.

(9)  For each Distribution Date, the interest rate for the Class LTII1B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "1" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average

     shall be computed by first subjecting the rate on such SWAP REMIC Regular
     Interest to a cap equal to Swap LIBOR for such Distribution Date.

(10) For each Distribution Date, the interest rate for the Class LTII2B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "2" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(11) The Class LT-IO Interest is an interest-only class that does not have a
     principal balance. For only those Distribution Dates listed in the first
     column of the table below, the Class LT-IO Interest shall be entitled to
     interest accrued on the SWAP REMIC Regular Interest listed in the second
     column below at a per annum rate equal to the excess, if any, of (i) the
     interest rate for such SWAP REMIC Regular Interest for such Distribution
     Date over (ii) Swap LIBOR for such Distribution Date.

calendar month immediately preceding the month in which such Distribution Date
occurs. All calculations of interest on each Class of LIBOR Certificates, their

payments of scheduled interest) (net of the Servicing Fee) on the related
Mortgage Loans that were due during the applicable Due Period and not received
as of the close of business on the related Determination Date, except as
provided in Section 4.01 hereof, less the aggregate amount of any such
Delinquent payments that the Servicer has determined would constitute a
Non-Recoverable Advance were an advance to be made with respect thereto;
provided, however, that with respect to (i) any Mortgage Loan which is not a

will be no obligation to make advances and, provided further, however, that with
respect to any Mortgage Loan that has been converted to an REO Property which is
less than 150 days delinquent, the obligation to make Advances shall only be to
payments of interest

Mortgage Loans as of the Cut-off Date)) will be added to the aggregate
Certificate Principal Balance of the Class C Certificates (on a pro rata basis).
Notwithstanding the immediately preceding sentence, however, to the extent any
excess referred to in the immediately preceding sentence is attributable to
distributions of proceeds of the Swap Agreement, such sentence shall be applied
by substituting "Class C Unpaid Realized Loss Amount" for "Class C Interest
Carry Forward Amount". Notwithstanding the foregoing on any Distribution Date
relating to a Due Period in which a Subsequent Recovery has been received by the

outstanding for which any Applied Realized Loss Amount has been allocated will
be increased, in order of seniority, by an amount equal to the lesser of (i) the
Unpaid Realized Loss Amount for such Class of Certificates and (ii) the total of

(reduced by the amount of the increase in the Certificate Principal Balance of
any more senior Class of Certificates pursuant to this sentence on such
Distribution Date).

hereof.

     Certificateholder or Holder: The Person in whose name a Certificate is
registered in the Certificate Register (initially, Cede & Co., as nominee for
the Depository) in the case of any Class of Regular Certificates or the Class R
Certificate, except that solely for the purpose of giving any consent pursuant
to this Agreement, any Certificate registered in the name of the Depositor or
any Affiliate of the Depositor shall be deemed not to be Outstanding and the
Percentage Interest evidenced thereby shall not be taken into account in
determining whether the requisite amount of Percentage Interests necessary to
effect such consent has been obtained; provided, however, that if any such
Person (including the Depositor) owns 100% of the Percentage Interests evidenced
by a Class of Certificates, such Certificates shall be deemed to be Outstanding
for purposes of any provision hereof that requires the consent of the Holders of
Certificates of a particular Class as a condition to the taking of any action
hereunder. The Trustee is entitled to rely conclusively on a certification of

                          CONVEYANCE OF MORTGAGE LOANS;
                         REPRESENTATIONS AND WARRANTIES

     SECTION 2.01. Conveyance of Mortgage Loans

     The Depositor, concurrently with the execution and delivery hereof, does
hereby sell, transfer, assign, set over and convey to the Trustee without
recourse all the right, title and interest of the Depositor in and to the assets
of the Trust Fund. Such assignment includes all interest and principal received
on or with respect to the Mortgage Loans on or after the Cut-off Date (other
than Scheduled Payments due on the Mortgage Loans on or before the Cut-off
Date).

     It is agreed and understood by the Depositor, the Servicer and the Trustee
that it is not intended that any Mortgage Loan be included in the Trust that is,
without limitation, either (i) a "High-Cost Home Loan" as defined in the New
Jersey Home Ownership Act effective November 27, 2003; (ii) a "High-Cost Home

     Mortgage Investors Trust, Mortgage Loan Asset-Backed Certificates, Series
     2006-RM4, without recourse" together with all riders thereto. The Mortgage
     Note shall include all intervening endorsements showing a complete chain of
     the title from the Transferor to [____________________].

          (B) Except as provided below and for each Mortgage Loan that is not a
     MERS Loan, the original recorded Mortgage together with all riders thereto,
     with evidence of recording thereon, or, if the original Mortgage has not
     yet been returned from the recording office, a copy of the original
     Mortgage together with all riders thereto certified to be a true copy of
     the original of the Mortgage that has been delivered for recording in the
     appropriate recording office of the jurisdiction in which the Mortgaged
     Property is located and in the case of each MERS Loan, the original
     Mortgage together with all riders thereto, noting the presence of the MIN
     of the Loan and either language indicating that the Mortgage Loan is a MOM
     Loan or if the Mortgage Loan was not a MOM Loan at origination, the
     original Mortgage and the assignment thereof to MERS, with evidence of
     recording indicated thereon, or a copy of the Mortgage certified by the
     public recording office in which such Mortgage has been recorded.

          (C) In the case of each Mortgage Loan that is not a MERS Loan, the

     Association, as trustee for the Merrill Lynch Mortgage Investors Trust,
     Mortgage Loan Asset-Backed Certificates, Series 2006-RM4."

                                      -65-

<PAGE>

          (D) The original policy of title insurance (or a preliminary title
     report, commitment or binder if the original title insurance policy has not
     been received from the title insurance company).

          (E) Originals of any intervening assignments of the Mortgage, with
     evidence of recording thereon or, if the original intervening assignment
     has not yet been returned from the recording office, a copy of such
     assignment certified to be a true copy of the original of the assignment
     which has been sent for recording in the appropriate jurisdiction in which
     the Mortgaged Property is located.

          (F) Originals of all assumption and modification agreements, if any.

          (G) If in connection with any Mortgage Loan, the Depositor cannot
     deliver the Mortgage, Assignments of Mortgage or assumption, consolidation
     or modification, as the case may be, with evidence of recording thereon, if
     applicable, concurrently with the execution and delivery of this Agreement
     solely because of a delay caused by the public recording office where such
     Mortgage, Assignments of Mortgage or assumption, consolidation or
     modification, as the case may be, has been delivered for recordation, the
     Depositor shall deliver or cause to be delivered to the Trustee written
     notice stating that such Mortgage or assumption, consolidation or
     modification, as the case may be, has been delivered to the appropriate
     public recording office for recordation. Thereafter, the Depositor shall
     deliver or cause to be delivered to the Trustee such Mortgage, Assignments
     of Mortgage or assumption, consolidation or modification, as the case may
     be, with evidence of recording indicated thereon, if applicable, upon
     receipt thereof from the public recording office. To the extent any
     required endorsement is not contained on a Mortgage Note or an Assignment
     of Mortgage, the Depositor shall make or cause to be made such endorsement.

          (H) With respect to any Mortgage Loan, none of the Depositor, the
     Servicer or the Trustee shall be obligated to cause to be recorded the
     Assignment of Mortgage referred to in this Section 2.01. In the event an
     Assignment of Mortgage is not recorded, the Servicer shall have no
     liability for its failure to receive and act on notices related to such
     Assignment of Mortgage.

     The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. Neither the Depositor nor the Servicer shall take any action
inconsistent with such ownership and shall not claim any ownership interest
therein. The Depositor and the Servicer shall respond to any third party
inquiries with respect to ownership of the Mortgage Loans by stating that such
ownership is held by the Trustee on behalf of the Certificateholders. Mortgage
documents relating to the Mortgage Loans not delivered to the Trustee are and
shall be held in trust by the Servicer, for the benefit of the Trustee as the
owner thereof, and the Servicer's possession of the contents of each Mortgage
File so retained is for the sole purpose of servicing the related Mortgage Loan,
and such retention and possession by the Servicer, is in a custodial capacity
only. The Depositor agrees to take no action inconsistent with the Trustee's
ownership of the Mortgage Loans, to promptly indicate to all inquiring parties
that the Mortgage Loans have been sold and to claim no ownership interest in the
Mortgage Loans.

     It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Sponsor to the Depositor is characterized as a pledge
and not a

                                      -66-

sale, then the Depositor shall be deemed to have transferred to the Trustee all
of the Depositor's right, title and interest in, to and under the obligations of
the Sponsor deemed to be secured by said pledge; and it is the intention of this
Agreement that the Depositor shall also be deemed to have granted to the Trustee
a first priority security interest in all of the Depositor's right, title, and
interest in, to and under the obligations of the Sponsor to the Depositor deemed
to be secured by said pledge and that the Trustee shall be deemed to be an
independent custodian for purposes of perfection of the security interest
granted to the Depositor. If the conveyance of the Mortgage Loans from the
Depositor to the Trustee is characterized as a pledge, it is the intention of
this Agreement that this Agreement shall constitute a security agreement under
applicable law, and that the Depositor shall be deemed to have granted to the
Trustee a first priority security interest in all of the Depositor's right,
title and interest in, to and under the Mortgage Loans, all payments of
principal of or interest on such Mortgage Loans, all other rights relating to
and payments made in respect of the Trust Fund, and all proceeds of any thereof.
If the trust created by this Agreement terminates prior to the satisfaction of
the claims of any Person in any Certificates, the security interest created
hereby shall continue in full force and effect and the Trustee shall be deemed
to be the collateral agent for the benefit of such Person.

     In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement, the rights in
the Transfer Agreements described therein, and the benefit of the repurchase
obligations and the obligation of the Sponsor contained in the Sale Agreement to
take, at the request of the Depositor or the Trustee, all action on its part
which is reasonably necessary to ensure the enforceability of a Mortgage Loan.
The Trustee hereby accepts such assignment, and shall be entitled to exercise
all rights of the Depositor under the Sale Agreement as if, for such purpose, it
were the Depositor. The foregoing sale, transfer, assignment, set-over, deposit
and conveyance does not and is not intended to result in creation or assumption
by the Trustee of any obligation of the Depositor, the Sponsor, or any other
Person in connection with the Mortgage Loans or any other agreement or
instrument relating thereto.

     SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans

     Except as set forth in the exception report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it holds and
will hold such documents and any other documents constituting a part of the
Mortgage Files delivered to it in trust for the use and benefit of all present
and future Certificateholders. The Depositor will cause the Sponsor to
repurchase any Mortgage Loan to which a material exception was taken in the
Exception Report unless such exception is cured to the satisfaction of the
Depositor and the Trustee within 45 Business Days of the Closing Date.

     The Trustee acknowledges receipt of the three Cap Contracts (forms of which
are attached hereto as Exhibits N-1, N-2 and N-3), the Transfer Agreement, the
Bring Down Letter and the Sale Agreement.

     The Trustee acknowledges receipt of the Swap Agreement that will be held in
the Supplemental Interest Trust and is hereby instructed to enter into the Swap
Agreement, not in its individual capacity, but solely as Trustee for the Issuing
Entity and for the Supplemental Interest Trust.

                                      -67-

<PAGE>

     The Trustee agrees, for the benefit of Certificateholders to review each
Mortgage File delivered to it within sixty (60) days after the Closing Date. The
Trustee will ascertain and to certify, within seventy (70) days of the Closing
Date, to the Depositor and the Servicer that all documents required by Section
2.01 (A)-(B), (C) (if applicable), and (D)-(E), and the documents if actually
received by it, under Section 2.01(F), have been executed and received, and that
such documents relate to the Mortgage Loans identified in Exhibit B-1 that have
been conveyed to it. It is herein acknowledged that, in conducting such review,
the Trustee shall not be under any 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, that they have actually been recorded or that they are other than what
they purport to be on their face. If the Trustee finds any document or documents
constituting a part of a Mortgage File to be missing or defective (that is,
mutilated, damaged, defaced or unexecuted) in any material respect, the Trustee
shall promptly (and in any event within no more than five Business Days) after
such finding so notify the Servicer, the Sponsor and the Depositor. In addition,
the Trustee shall also notify the Servicer, the Sponsor and the Depositor if the
original Mortgage with evidence of recording thereon with respect to a Mortgage
Loan is not received within seventy (70) days of the Closing Date; if it has not
been received because of a delay caused by the public recording office where
such Mortgage has been delivered for recordation, the Depositor shall deliver or
cause to be delivered to the Trustee written notice stating that such Mortgage
has been delivered to the appropriate public recording office for recordation
and thereafter the Depositor shall deliver or cause to be delivered such
Mortgage with evidence of recording thereon upon receipt thereof from the public
recording office. The Trustee shall request that the Sponsor correct or cure
such omission, defect or other irregularity, or substitute a Mortgage Loan
pursuant to the provisions of Section 2.03(c), within ninety (90) days from the
date the Sponsor was notified of such omission or defect and, if the Sponsor
does not correct or cure such omission or defect within such period, that the
Sponsor purchase such Mortgage Loan from the Issuing Entity within ninety (90)
days from the date the Trustee notified the Sponsor of such omission, defect or
other irregularity at the Purchase Price of such Mortgage Loan. The Purchase
Price for any Mortgage Loan purchased pursuant to this Section 2.02 shall be
paid to the Servicer and deposited by the Servicer in the Certificate Account or
Collection Account, as appropriate, promptly upon receipt, and upon receipt by
the Trustee of written notification of such deposit signed by a Servicing
Officer or receipt of such deposit by the Trustee, the Trustee, upon receipt of
a Request for Release and certification of the Servicer of such required
deposit, shall promptly release to the Sponsor the related Mortgage File and the
Trustee shall execute and deliver such instruments of transfer or assignment,
without recourse, as shall be requested by the Sponsor and necessary to vest in
the Sponsor or its designee, as the case may be, any Mortgage Loan released
pursuant hereto, and the Trustee shall have no further responsibility with
regard to such Mortgage Loan. It is understood and agreed that the obligation of
the Sponsor to purchase, cure or substitute any Mortgage Loan as to which a
material defect in or omission of a constituent document exists shall constitute
the sole remedy respecting such defect or omission available to the Trustee on
behalf of Certificateholders. The preceding sentence shall not, however, limit
any remedies available to the Certificateholders, the Depositor or the Trustee
pursuant to the Sale Agreement, the Transfer Agreement or the Bring Down Letter.
The Trustee shall be under no duty or obligation to inspect, review and examine
such documents, instruments, certificates or other papers to determine that they
are genuine, enforceable, recordable, duly authorized, sufficient, legal, valid
or appropriate to the represented purpose, or that they have actually been
recorded, or that they are other than what they purport to be on their face. The
Servicer and the Trustee shall keep confidential the name of each Mortgagor
except as required for the performance of this Agreement and the Servicer and
the Trustee shall not solicit any such Mortgagor for the purpose of refinancing
the related Mortgage Loan; notwithstanding anything herein to the contrary, the
foregoing shall not be construed to prohibit (i) disclosure of any and all
information that is or becomes publicly known, or information obtained by the
Trustee or the Servicer from sources other

                                      -68-

<PAGE>

than the other parties hereto, (ii) disclosure of any and all information (A) if
required to do so by any applicable law, rule or regulation, (B) to any
government agency or regulatory body having or claiming authority to regulate or
oversee any aspects of the business of the Trustee or the Servicer or that of
any Affiliate, (C) pursuant to any subpoena, civil investigation demand or
similar demand or request of any court, regulatory authority, arbitrator or
arbitration to which the Trustee or the Servicer or any Affiliate or an officer,
director, employer or shareholder thereof is a party or (D) to any Affiliate,
independent or internal auditor, agent, employee or attorney of the Trustee or
the Servicer having a need to know the same, provided that the Trustee or the
Servicer, as applicable, advises such recipient of the confidential nature of
the information being disclosed, or (iii) any other disclosure authorized by the
Depositor.

     Within seventy (70) days of the Closing Date, the Trustee shall deliver to
the Depositor and the Servicer the Trustee's Certification, substantially in the
form of Exhibit D attached hereto, evidencing the completeness of the Mortgage
Files, with any exceptions noted thereto.

     SECTION 2.03. Representations, Warranties and Covenants of the Depositor

          (a) The Depositor hereby represents and warrants to the Servicer and
the Trustee as follows, as of the date hereof:

          (i) The Depositor is duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware and
     has full power and authority (corporate and other) necessary to own or hold
     its properties and to conduct its business as now conducted by it and to
     enter into and perform its obligations under this Agreement and the Sale
     Agreement.

          (ii) The Depositor has the full corporate power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and the Sale Agreement and has
     duly authorized, by all necessary corporate action on its part, the
     execution, delivery and performance of this Agreement and the Sale
     Agreement; and this Agreement and the Sale Agreement, assuming the due
     authorization, execution and delivery hereof by the other parties hereto,
     constitutes a legal, valid and binding obligation of the Depositor,
     enforceable against the Depositor in accordance with its terms, subject, as
     to enforceability, to (i) bankruptcy, insolvency, reorganization,
     moratorium and other similar laws affecting creditors' rights generally and
     (ii) general principles of equity, regardless of whether enforcement is
     sought in a proceeding in equity or at law.

          (iii) The execution and delivery of this Agreement and the Sale
     Agreement by the Depositor, the consummation of the transactions
     contemplated by this Agreement and the Sale Agreement, and the fulfillment
     of or compliance with the terms hereof are in the ordinary course of
     business of the Depositor and will not (A) result in a material breach of
     any term or provision of the charter or by-laws of the Depositor or (B)
     materially conflict with, result in a violation or acceleration of, or
     result in a material default under, the terms of any other material
     agreement or instrument to which the Depositor is a party or by which it
     may be bound or (C) constitute a material violation of any statute, order
     or regulation applicable to the Depositor of any court, regulatory body,
     administrative agency or governmental body having jurisdiction over the
     Depositor; and the Depositor is not in breach or violation of any material
     indenture or other material agreement or instrument, or in violation of any
     statute, order or regulation of any court, regulatory body, administrative
     agency or governmental body having jurisdiction over it which

                                      -69-

<PAGE>

     breach or violation may materially impair the Depositor's ability to
     perform or meet any of its obligations under this Agreement.

          (iv) No litigation is pending, or, to the best of the Depositor's
     knowledge, threatened, against the Depositor that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement and the Sale Agreement or the ability of the Depositor to perform
     its obligations under this Agreement and the Sale Agreement in accordance
     with the terms hereof.

          (v) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Depositor of, or compliance by the Depositor with, this
     Agreement and the Sale Agreement or the consummation of the transactions
     contemplated hereby, or if any such consent, approval, authorization or
     order is required, the Depositor has obtained the same. The Depositor
     hereby represents and warrants to the Trustee with respect to each Mortgage
     Loan as of the Closing Date, and following the transfer of the Mortgage
     Loans to it by the Sponsor, the Depositor had good title to the Mortgage
     Loans and the Mortgage Notes were subject to no offsets, claims, liens,
     mortgage, pledge, charge, security interest, defenses or counterclaims.

          (b) The representations and warranties of the Transferor with respect
to the related Mortgage Loans in the Transfer Agreement, which have been
assigned to the Trustee hereunder, were made as of the date specified in the
Transfer Agreement and brought forward to the Closing Date pursuant to the Bring
Down Letter. The representations and warranties of the Transferor with respect
to the Mortgage Loans contained in the Bring Down Letter were made as of the
Closing Date. The representations and warranties of the Sponsor with respect to
the Mortgage Loans contained in the Sale Agreement were made as of the Closing
Date. To the extent that any fact, condition or event with respect to a Mortgage
Loan constitutes a breach of a representation or warranty of the Sponsor under
the Sale Agreement, the obligations of the Sponsor under the Sale Agreement
shall be enforced against the Sponsor, as set forth in the Sale Agreement. The
Trustee acknowledges that the Depositor shall have no obligation or liability
with respect to any breach of any representation or warranty with respect to the
Mortgage Loans (except as set forth in Section 2.03(a)(v)) under any
circumstances.

     In addition to the representations and warranties of the Transferor in the
Transfer Agreement that were brought forward to the Closing Date pursuant to the
Bring Down Letter, with respect to each Mortgage Loan, the Transferor made
certain additional covenants regarding such Mortgage Loan, as set forth in the
Transfer Agreement. With respect to any breach of such additional covenants that
materially and adversely affects the interests of the Certificateholders in such
Mortgage Loan, the Sponsor shall repurchase such Mortgage Loan in accordance
with this Section 2.03.

          (c) Upon discovery by any of the Depositor, the Servicer or the
Trustee (or its custodian) of a breach of any of such representations and
warranties that adversely and materially affects the value of the related
Mortgage Loan, Prepayment Charges or the interests of the Certificateholders,
the party discovering such breach shall give prompt written notice to the other
parties. Within ninety (90) days of the discovery of such breach of any
representation or warranty, the Sponsor shall either (a) cure such breach in all
material respects, (b) repurchase such Mortgage Loan or any property acquired in
respect thereof from the Trustee at the Purchase Price or (c) within the two
year period following the Closing Date, substitute a Replacement Mortgage Loan
for the affected Mortgage Loan. In the event of discovery of a breach of any
representation and warranty of the Sponsor, the Trustee's rights shall be

                                      -70-
<PAGE>

enforced under the Sale Agreement for the benefit of Certificateholders. If a
breach of the representations and warranties set forth in the Transfer Agreement
hereof exists solely due to the unenforceability of a Prepayment Charge, the
Trustee or the other party having notice thereof shall notify the Servicer
thereof and not seek to enforce the repurchase remedy provided for herein unless
such Mortgage Loan is not current. In the event of a breach of the
representations and warranties with respect to the Mortgage Loans set forth in
the Transfer Agreement, the Trustee shall enforce the right of the Issuing
Entity to be indemnified for such breach of representation and warranty. In the
event that such breach relates solely to the unenforceability of a Prepayment
Charge, amounts received in respect of such indemnity up to the amount of such
Prepayment Charge shall be distributed pursuant to Section 4.04(b)(i). As
provided in the Sale Agreement, if the Sponsor substitutes for a Mortgage Loan
for which there is a breach of any representations and warranties in the
Transfer Agreement which adversely and materially affects the value of such
Mortgage Loan and such substitute mortgage loan is not a Replacement Mortgage
Loan, under the terms of the Sale Agreement, the Sponsor will, in exchange for
such substitute Mortgage Loan, (i) provide the applicable Purchase Price for the
affected Mortgage Loan or (ii) within two years of the Closing Date, substitute
such affected Mortgage Loan with a Replacement Mortgage Loan. Any such
substitution shall not be effected prior to the additional delivery to the
Trustee of a Request for Release substantially in the form of Exhibit I and
shall not be effected unless it is within two years of the Startup Day. As
provided in the Sale Agreement, the Sponsor indemnifies and holds the Issuing
Entity, the Trustee (or its custodian, as applicable), the Depositor, the
Servicer and each Certificateholder harmless against any and all taxes, claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Issuing Entity, the
Trustee (or its custodian, as applicable), the Depositor, the Servicer and any
Certificateholder may sustain in connection with any actions of the Sponsor
relating to a repurchase of a Mortgage Loan other than in compliance with the
terms of this Section 2.03 and the Sale Agreement, to the extent that any such
action causes (i) any federal or state tax to be imposed on the Issuing Entity
or any REMIC provided for herein, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup day" under Section 860G(d)(1) of the Code, or
(ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding. In furtherance of the foregoing, if the Sponsor
is not a member of MERS and repurchases a Mortgage Loan which is registered on
the MERS System, the Sponsor, at its own expense and without any right of
reimbursement, shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Sponsor
and shall cause such Mortgage to be removed from registration on the MERS System
in accordance with MERS' rules and regulations.

     With respect to any Mortgage Loan repurchased by the Sponsor pursuant to
the Sale Agreement, the principal portion of the funds received by the Servicer
in respect of such repurchase of a Mortgage Loan will be considered a Principal
Prepayment and shall be deposited in the Certificate Account pursuant to Section
3.05. Upon receipt by the Trustee of notice from the Servicer of receipt by the
Servicer of the full amount of the Purchase Price for a Deleted Mortgage Loan,
and upon receipt by the Trustee of the Mortgage File for a Replacement Mortgage
Loan substituted for a Deleted Mortgage Loan and a Request for Release, the
Trustee shall release and reassign to the Sponsor the related Mortgage File for
the Deleted Mortgage Loan and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, representation or
warranty, as shall be necessary to vest in such party or its designee or
assignee title to any Deleted Mortgage Loan released pursuant hereto, free and
clear of all security interests, liens and other encumbrances created by this
Agreement, which instruments shall be prepared by the Depositor or the Sponsor,
and the Trustee (and its custodian) shall have no further responsibility with
respect to the Mortgage File relating to such Deleted Mortgage Loan.

                                      -71-

<PAGE>

     With respect to each Replacement Mortgage Loan to be delivered to the
Trustee pursuant to the terms of this Article II in exchange for a Deleted
Mortgage Loan: (i) the Sponsor must deliver to the Trustee the Mortgage File for
the Replacement Mortgage Loan containing the documents set forth in Section 2.01
along with a written certification certifying as to the Mortgage Loan satisfying
all requirements under the definition of Replacement Mortgage Loan and the
delivery of such Mortgage File and containing the granting language set forth in
Section 2.01; and (ii) the Depositor will be deemed to have made, with respect
to such Replacement Mortgage Loan, each of the representations and warranties
made by it with respect to the related Deleted Mortgage Loan. The Trustee shall
review the Mortgage File with respect to each Replacement Mortgage Loan and
certify to the Depositor that all documents required by Section 2.01(A)-(B), (C)
(if applicable), and (D)-(E) have been executed and received.

     For any month in which the Sponsor substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Sponsor will
determine the amount (if any) by which the aggregate principal balance of all
such Replacement Mortgage Loans as of the date of substitution and the aggregate
Prepayment Charges with respect to such Replacement Mortgage Loans is less than
the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
Prepayment Charges of all such Deleted Mortgage Loans. An amount equal to the
aggregate of the deficiencies described in the preceding sentence (such amount,
the "Substitution Adjustment Amount") plus an amount equal to any unreimbursed
costs, penalties and/or damages incurred by the Trust Fund in connection with
any violation relating to such Deleted Mortgage Loan of any predatory or abusive
lending law shall be remitted by the Sponsor to the Trustee for deposit into the
Certificate Account by the Sponsor on the Determination Date for the
Distribution Date relating to the Prepayment Period during which the related
Mortgage Loan became required to be purchased or replaced hereunder.

     Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Replacement Mortgage Loan for a
Deleted Mortgage Loan shall be made unless the Trustee shall have received an
Opinion of Counsel (at the expense of the party seeking to make the
substitution) that, under current law, such substitution will not (A) affect
adversely the status of any REMIC established hereunder as a REMIC, or of the
related "regular interests" as "regular interests" in any such REMIC, or (B)
cause any such REMIC to engage in a "prohibited transaction" or prohibited
contribution pursuant to the REMIC Provisions.

     The Depositor shall amend the Mortgage Loan Schedule to reflect the removal
of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Replacement Mortgage Loan or Replacement Mortgage Loans.
Upon such substitution by the Sponsor, such Replacement Mortgage Loan or
Replacement Mortgage Loans shall constitute part of the Mortgage Pool and shall
be subject in all respects to the terms of this Agreement and the applicable
Sale Agreement, including all applicable representations and warranties thereof
included in the applicable Sale Agreement as of the date of substitution.

          (d) It is understood and agreed that the representations, warranties
and indemnification (i) set forth in this Section 2.03, (ii) of the Sponsor and
the Depositor set forth in the Sale Agreement and assigned to the Trustee by the
Depositor hereunder and (iii) of the Transferor, assigned by the Sponsor to the
Depositor pursuant to the Sale Agreement and assigned to the Trustee by the
Depositor hereunder shall each survive delivery of the Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue
throughout the term of this Agreement.

                                      -72-

<PAGE>

          (e) The Depositor shall deliver a copy of the Mortgage Loan Schedule
to the Servicer on the Closing Date.

          (f) The Depositor shall notify the Servicer and the Trustee when any
NIM Notes are issued and when such NIM Notes are no longer outstanding.

     SECTION 2.04. Representations and Warranties of the Servicer

          (a) The Servicer hereby represents and warrants to the Depositor and
the Trustee as follows, as of the date hereof:

          (i) The Servicer is duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Nevada and is

     Agreement, assuming the due authorization, execution and delivery hereof by
     the other parties hereto, constitutes a legal, valid and binding obligation
     of the Servicer, enforceable against the Servicer in accordance with its
     terms, except that (a) the enforceability hereof may be limited by
     bankruptcy, insolvency, moratorium, receivership and other similar laws
     relating to creditors' rights generally and (b) the remedy of specific
     performance and injunctive and other forms of equitable relief may be
     subject to equitable defenses and to the discretion of the court before

          (iii) The execution and delivery of this Agreement by the Servicer,
     the servicing of the Mortgage Loans under this Agreement, the consummation
     of any other of the transactions contemplated by this Agreement, and the
     fulfillment of or compliance with the terms hereof are in the ordinary
     course of business of the Servicer and will not (A) result in a material
     breach of any term or provision of the charter or by-laws of the Servicer
     or (B) materially conflict with, result in a material breach, violation or
     acceleration of, or result in a material default under, the terms of any
     other material agreement or instrument to which the Servicer is a party or
     by which it may be bound, or (C) constitute a material violation of any
     statute, order or regulation applicable to the Servicer of any court,

     to Equifax, Experian and Trans Union Credit Information Company on a
     monthly basis.

     SECTION 2.05. Substitutions and Repurchases of Mortgage Loans that are not
"Qualified Mortgages"

Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected
Mortgage Loan within ninety (90) days of such discovery in the same manner as it

REMIC and the SWAP REMIC as a REMIC. The Trustee shall sign the returns
providing for such elections and such other tax or information returns that are
required to be signed by the Trustee under applicable law. This Agreement shall
be construed so as to carry out the intention of the parties that each of the
Upper Tier REMIC, the Lower Tier REMIC and the SWAP REMIC be treated as a REMIC
at all times prior to the date on which the Trust Fund is terminated.

          (b) The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby. The "Startup Day" for purposes of the REMIC Provisions shall be the
Closing Date. Each REMIC's fiscal year shall be the calendar year.

     The SWAP REMIC shall consist of all of the assets of the Trust Fund, other
than (i) amounts distributable to the Class P Certificates pursuant to Section
4.04(b)(i) hereof, (ii) the interests issued by the SWAP REMIC and the interests
issued by the Lower Tier REMIC, (iii) the grantor trusts described in Section
2.07 hereof, (iv) each Cap Contract and (v) the Swap Agreement and the
Supplemental Interest Trust. The SWAP REMIC shall issue the SWAP REMIC Regular
Interests, which shall be designated as regular interests of such REMIC, and
shall issue the Class SWR Interest, which shall be designated as the sole class
of residual interest in the SWAP REMIC. Each of the SWAP REMIC Regular Interests
shall have the characteristics set forth in the Preliminary Statement and this
Section 2.07.

     The Lower Tier REMIC shall consist of the SWAP REMIC Regular Interests. The
Lower Tier REMIC shall issue the Lower Tier REMIC Regular Interests, which shall
be designated as regular interests of such REMIC and shall issue the Class LTR
Interest, which shall be designated as the sole class of residual interest in
the Lower Tier REMIC. Each of the Lower Tier REMIC Regular Interests shall have
the characteristics set forth in its definition and the Preliminary Statement.

     The assets of the Upper Tier REMIC shall be the Lower Tier REMIC Regular
Interests. The REMIC Regular Interests shall be designated as the regular
interests in the Upper Tier REMIC and the Residual Interest shall be designated
as the sole class of residual interest in the Upper Tier REMIC. For federal
income tax purposes, the pass-through rate on each REMIC Regular Interest (other
than the Uncertificated Class C Interest and the Class UT-IO Interest) and on
the sole class of residual interest in the Upper Tier REMIC shall be subject to
a cap equal to the Upper Tier REMIC Net WAC Cap.

     The beneficial ownership of the Class SWR Interest, the Class LTR Interest
and the Residual Interest shall be represented by the Class R Certificate. The
Class SWR Interest and the Class LTR Interest shall not have a principal balance
or bear interest.

          (c) The "tax matters person" with respect to each REMIC for purposes
of the REMIC Provisions shall be the beneficial owner of the Class R
Certificate; provided, however, that the Holder of the Class R Certificate, by
its acceptance thereof, irrevocably appoints the Trustee as its agent and
attorney-in-fact to act as "tax matters person" with respect to each such REMIC
for purposes of the REMIC Provisions. If there is more than one beneficial owner
of the Class R Certificate, the "tax matters person" shall be the Person with
the greatest percentage interest in the Class R Certificate and, if there is
more than one such Person, shall be determined under Treasury regulation Section
1.860F-4(d) and Treasury regulation Section 301.6231(a)(7)-1.

          (d) (i) It is intended that the rights of each Class of the Class A,
Class M and Class B Certificates to receive payments in respect of Excess
Interest shall be treated as a right in interest rate cap contracts written by
the Class C Certificateholders in favor of the holders of each Class of the
Class A, Class M and Class B Certificates and such shall be accounted for as
property held separate and apart from the regular interests in the Upper Tier
REMIC held by the holders of the Class A Certificates (other than the Class R
Certificate), Class M Certificates, Class B Certificates and the residual
interest in the Upper Tier REMIC held by the holder of the Class R Certificate.
For information reporting requirements, the rights of the Class A, Class M and
Class B Certificates to receive payments in respect of Excess Interest shall be
assumed to have zero or a de minimis value. This provision is intended to
satisfy the requirements of Treasury Regulations Section 1.860G-2(i) for the
treatment of property rights coupled with REMIC interests to be separately
respected and shall be interpreted consistently with such regulation. On each
Distribution Date, to the extent that any of the Class A, Class M and Class B
Certificates receive payments in respect of Excess Interest, such amounts, to
the extent not derived from payments on the Cap Contracts or the Swap Agreement,
will be treated as distributed by the Upper Tier REMIC to the Class C
Certificates pro rata in payment of the amounts specified in Section 4.04(g) and
then paid to the relevant Class of Certificates pursuant to the related interest
rate cap agreement.

          (ii) It is intended that the beneficial owners of the Certificates
(other than the Class P and Class C Certificates) shall be treated as having
entered into a notional principal contract with respect to the beneficial owners
of the Class C Certificates. Pursuant to each such notional principal contract,
all beneficial owners of each Class of Certificates (other than the Class P and
Class C Certificates) shall be treated as having agreed to pay, on each
Distribution Date, to the beneficial owners of the Class C Certificates an
aggregate amount equal to the excess, if any, of (i) the amount payable on such
Distribution Date on the Corresponding REMIC Regular Interest of such Class of
Certificates over (ii) the amount payable on such Class of Certificates on such
Distribution Date (such excess, a "Class Payment Shortfall"). A Class Payment
Shortfall shall be allocated to each Class of Certificates to the extent that
interest accrued on such Class for the related Accrual Period at the
Pass-Through Rate for a Class, computed by substituting "Upper Tier REMIC Net
WAC Cap" for the Available Funds Cap set forth in the definition thereof,
exceeds the amount of interest accrued on such Certificate at the Pass-Through
Rate (without such substitution) for the related Accrual Period, and a Class
Payment Shortfall payable from principal collections shall be allocated to the
most subordinate Class of Certificates with an outstanding principal balance to
the extent of such balance.

          (e) The parties intend that the portion of the Trust Fund consisting
of the Uncertificated Class C Interest, the uncertificated Class UT-IO Interest,
the rights to receive payments deemed made by the Class A, Class M and Class B
Certificates in respect of notional principal contracts described in Section
2.07(d)(ii), the Supplemental Interest Trust which holds the Swap Agreement, the
Cap Contracts and the obligation of the holders of the Class C Certificates to
pay amounts in respect of Excess Interest to the holders of the Class A, Class M
and Class B Certificates shall be treated as a "grantor trust" under the Code,
for the benefit of the holders of the Class C Certificates, and the provisions
hereof shall be interpreted consistently with this intention. In furtherance of
such intention, the Trustee shall (i) furnish or cause to be furnished to the
holders of the Class C Certificates information regarding their allocable share,
if any, of the income with respect to such grantor trust, (ii) file or cause to
be filed with the Internal Revenue Service Form 1041 (together with any
necessary attachments) and such other forms as may be applicable and (iii)
comply with such information reporting obligations with respect to payments from
such grantor trust to the holders of Class A, Class M, Class B and Class C
Certificates as may be applicable under the Code.

                                      -76-

<PAGE>

          (f) The parties intend that the portion of the Trust Fund consisting
of the right to receive amounts distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class P Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class P Certificates information regarding their
allocable share of the income with respect to such grantor trust and (ii) file
or cause to be filed with the Internal Revenue Service Form 1041 (together with
any necessary attachments) and such other forms as may be applicable.

          (g) The parties intend that amounts paid to the Swap Counterparty
under the Swap Agreement shall be deemed for federal income tax purposes to be
paid by the Class C Certificates first, out of funds deemed received in respect
of the Class UT-IO Interest, second, out of funds deemed received in respect of
the Uncertificated Class C Interest and third, out of funds deemed received in
respect of notional principal contracts described in Section 2.07(d)(ii), and
the provisions hereof shall be interpreted consistently with this intention. On
each Distribution Date, to the extent that amounts paid to the Swap Counterparty
are deemed paid out of funds received in respect of the Uncertificated Class C
Interest, such amounts will be treated as distributed by the Upper Tier REMIC to
the Class C Certificates pro rata in payment of the amounts specified in Section
4.04(g) and then paid to the Swap Counterparty pursuant to the Swap Agreement.

     The Supplemental Interest Trust shall be an "outside reserve fund" for
federal income tax purposes and not an asset of any REMIC. Furthermore, the
Holders of the Class C Certificates shall be the beneficial owners of the
Supplemental Interest Trust for all federal income tax purposes, and shall be
taxable on all income earned thereon.

          (h) All payments of principal and interest at the Net Mortgage Rate on
each of the Mortgage Loans (other than amounts distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof) received by the SWAP REMIC
with respect to the Mortgage Loans shall be paid to the SWAP REMIC Regular
Interests until the principal balance of all such interests have been reduced to
zero and any losses allocated to such interests have been reimbursed. Any
available funds remaining in the SWAP REMIC on a Distribution Date after
distributions to the SWAP REMIC Regular Interests shall be distributed to the
Class R Certificates on account of the Class SWR Interest. On each Distribution
Date, the Trustee shall distribute the aggregate Interest Funds (net of expenses
and payments to the Class P Certificates) with respect to each of the SWAP REMIC
Regular Interests based on the interest rates for each such SWAP REMIC Regular
Interest. On each Distribution Date, the Trustee shall distribute the aggregate
Principal Funds with respect to the Group One Mortgage Loans first to the Class
1-SW1 Interest until its principal balance is reduced to zero and then
sequentially to each of the other SWAP REMIC Regular Interests beginning with
designation "1" in ascending order of their numerical class designation, in
equal amounts to each such class in such numerical designation, until the
principal balance of each such class is reduced to zero. All losses with respect
to the Group One Mortgage Loans shall be allocated among the SWAP REMIC Regular
Interests beginning with the designation "1" in the same manner that principal
distributions are allocated. On each Distribution Date, the Trustee shall
distribute the aggregate Principal Funds with respect to the Group Two Mortgage
Loans first to the Class 2-SW2 Interest until its principal balance is reduced
to zero and then sequentially to each of the other SWAP REMIC Regular Interests
beginning with designation "2" in ascending order of their numerical class
designation, in equal amounts to each such class in such numerical designation,
until the principal balance of each such class is reduced to zero. All losses
with respect to the Group Two Mortgage Loans shall be allocated among the SWAP
REMIC Regular Interests beginning with the designation "2" in the same

                                      -77-

<PAGE>

manner that principal distributions are allocated. Subsequent Recoveries with
respect to the Group One and Group Two Mortgage Loans shall be allocated in the
reverse fashion from the manner in which losses are allocated.

     All payments received by the Lower Tier REMIC with respect to the SWAP
REMIC Regular Interests shall be paid to the Lower Tier REMIC Regular Interests
until the principal balance of all such interests have been reduced to zero and
any losses allocated to such interests have been reimbursed. Any excess amounts
shall be distributed to the Class LTR Interest. On each Distribution Date,
payments and losses shall be allocated among the Lower Tier REMIC Regular
Interests so that (i) each of the Lower Tier REMIC I Marker Interests shall have
a principal balance equal to 25% of the principal balance of the Corresponding
Certificates, (ii) the Class LTIX Interest has a principal balance equal to the
excess of (x) 50% of the remaining principal balance of the Mortgage Loans over
(y) the aggregate principal balance of the Lower Tier REMIC I Marker Interests
(if necessary to reflect an increase in overcollateralization, accrued and
unpaid interest on the Class LTIX interest may be added to its principal amount
to achieve this result) and (iii) the aggregate principal amount of the Class
LTII1A Interest, Class LTII1B Interest, Class LTII2A Interest, Class LTII2B
Interest and Class LTIIX Interest shall equal 50% of the remaining principal
balance of the Mortgage Loans. Distributions and losses allocated to the Lower
Tier REMIC Regular Interests described in clause (iii) of the preceding sentence
will be allocated among such Lower Tier REMIC Regular Interests in the following
manner: (x) such distributions shall be deemed made to such Lower Tier REMIC
Regular Interests first, so as to keep the principal balance of the each such
Lower Tier REMIC Regular Interest with "B" at the end of its designation equal
to 0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
the related Mortgage Group and second, to such Lower Tier REMIC Regular
Interests with "A" at the end of its designation so that the uncertificated
principal balance of each such Lower Tier REMIC Regular Interest is equal to
0.05% of the excess of (I) the aggregate scheduled principal balance of the
Mortgage Loans in the related Mortgage Group over (II) the aggregate principal
balance of Certificate Group One, in the case of the Class LTII1A Interest, or
Certificate Group Two, in the case of the Class LTII2A Interest (except that if
0.05% of any such excess is greater than the principal amount of the related
Lower Tier REMIC II Marker Interest with "A" at the end of its designation, the
least amount of principal shall be distributed to each Lower Tier REMIC II
Marker Interest with "A" at the end of its designation such that the Lower Tier
REMIC Subordinated Balance Ratio is maintained) and finally, any remaining
distributions of principal to the Class LTIIX Interest and (y) such losses shall
be allocated among the Lower Tier REMIC Regular Interests described in clause
(iii) of the preceding sentence first, so as to keep the principal balance of
the each such Lower Tier REMIC Regular Interest with "B" at the end of its
designation equal to 0.05% of the aggregate scheduled principal balance of the
Mortgage Loans in the related Mortgage Group; second, to such Lower Tier REMIC
Regular Interests with "A" at the end of its designation so that the
uncertificated principal balance of each such Lower Tier REMIC Regular Interest
is equal to 0.05% of the excess of (I) the aggregate scheduled principal balance
of the Mortgage Loans in the related Mortgage Group over (II) the aggregate
principal balance of Certificate Group One, in the case of the Class LTII1A
Interest, or Certificate Group Two, in the case of the Class LTII2A Interest
(except that if 0.05% of any such excess is greater than the principal amount of
the related Lower Tier REMIC II Marker Interest with "A" at the end of its
designation, the least amount of losses shall be allocated to each Lower REMIC
II Marker Interest with "A" at the end of its designation such that the Lower
Tier REMIC Subordinated Balance Ratio is maintained) and finally, any remaining
losses to the Class LTIIX Interest. Notwithstanding the preceding two sentences,
however, losses not allocated to any Class of Certificates will not be allocated
to any Lower Tier REMIC Regular Interests. All computations with respect to the
Lower Tier REMIC Regular Interests shall be taken out to ten decimal places.

                                      -78-

<PAGE>

     Any available funds remaining in the Lower Tier REMIC on a Distribution
Date after distributions to the Lower Tier REMIC Regular Interests shall be
distributed to the Class R Certificates in respect of the Class LTR Interest.

     If on any Distribution Date the Certificate Principal Balance of any Class
of Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amounts of the Lower Tier REMIC Regular Interests, with such
increase allocated (before the making of distributions and the allocation of
losses on the Lower Tier REMIC Regular Interests on such Distribution Date)
among the Lower Tier REMIC Regular Interests so that, to the greatest extent
possible, (i) each of the Lower Tier REMIC I Marker Interests has a principal
balance equal to 25% of the principal balance of the Corresponding Certificates,
(ii) the Class LTIX Interest has a principal balance equal to the excess of (x)
50% of the remaining principal balance of the Mortgage Loans over (y) the
aggregate principal balance of the Lower Tier REMIC I Marker Interests and (iii)
the aggregate principal amount of the Lower Tier REMIC II Marker Interests and
the Class LTIIX Interest shall equal 50% of the remaining principal balance of
the Mortgage Loans. Allocations in connection with clause (iii) shall be made so
that, to the greatest extent possible, (a) the principal balance of each Lower
Tier REMIC II Marker Interest with "B" at the end of its designation equals
0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group, (b) the principal balance of each Lower Tier REMIC II
Marker Interest with "A" at the end of its designation equals 0.05% of the
excess of (x) the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group over (y) the aggregate principal balance of Certificate
Group One in the case of the Class LTII1A Interest, or Certificate Group Two in
the case of the Class LTII2A Interest and (c) any remaining allocations are made
to the Class LTIIX Interest.

          (i) In the event that any REMIC provided for herein fails to qualify
as a REMIC, loses its status as a REMIC or incurs federal, state or local taxes
as a result of a prohibited transaction or prohibited contribution under the
REMIC Provisions due to the negligent performance by the Servicer of its duties
and obligations set forth herein, the Servicer shall indemnify the Trustee and
the Issuing Entity against any and all Losses resulting from such negligence;
provided, however, that the Servicer shall not be liable for any such Losses
attributable to the action or inaction of the Trustee, the Depositor or the
Holder of the residual interest in such REMIC, as applicable, nor for any such
Losses resulting from misinformation provided by the Holder of the residual
interest in such REMIC on which the Servicer has relied. The foregoing shall not
be deemed to limit or restrict the rights and remedies of the Holder of the
residual interest in such REMIC now or hereafter existing at law or in equity.
Notwithstanding the foregoing, however, in no event shall the Servicer have any
liability (1) for any action or omission that is taken in accordance with and in
compliance with the express terms of, or which is expressly permitted by the
terms of, this Agreement, (2) for any Losses other than those arising out of a
negligent performance by the Servicer of its duties and obligations set forth
herein, and (3) for any special or consequential damages to Certificateholders
(in addition to payment of principal and interest on the Certificates).

          (j) In the event that any REMIC provided for herein fails to qualify
as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes
as a result of a prohibited transaction or prohibited contribution under the
REMIC Provisions due to the negligent performance by the Trustee of its duties
and obligations set forth herein, the Trustee shall indemnify the Issuing Entity
against any and all Losses resulting from such negligence; provided, however,
that the Trustee shall not be liable for any such Losses attributable to the
action or inaction of the Servicer, the Depositor or the Holder of the residual
interest in such REMIC, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of the residual interest in such REMIC on
which the Trustee has relied. The

                                      -79-

<PAGE>

foregoing shall not be deemed to limit or restrict the rights and remedies of
the Holder of the residual interest in such REMIC now or hereafter existing at
law or in equity. Notwithstanding the foregoing, however, in no event shall the
Trustee have any liability (1) for any action or omission that is taken in
accordance with and in compliance with the express terms of, or which is
expressly permitted by the terms of, this Agreement, (2) for any Losses other
than those arising out of a negligent performance by the Trustee of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

     SECTION 2.08. [RESERVED]

     SECTION 2.09. Covenants of the Servicer

     The Servicer hereby covenants to each of the other parties to this
Agreement that the Servicer shall comply in the performance of its obligations
under this Agreement with all reasonable rules and requirements of the insurer
under each Required Insurance Policy.

     SECTION 2.10. [RESERVED]

     SECTION 2.11. Permitted Activities of the Issuing Entity

     The Issuing Entity is created for the object and purpose of engaging in the
Permitted Activities. In furtherance of the foregoing, the Trustee is hereby
authorized and directed to execute and deliver on behalf of the Supplemental
Interest Trust, and to perform the duties and obligations of the Supplemental
Interest Trust under, the Cap Contracts and the Swap Agreement and any other
agreement or instrument related thereto, in each case in such form as the
Depositor shall direct or shall approve in writing, the execution and delivery
of any such agreement by the Depositor to be conclusive evidence of its approval
thereof.

     SECTION 2.12. Qualifying Special Purpose Entity

     For purposes of SFAS 140, the parties hereto intend that the Issuing Entity
shall be treated as a "qualifying special purpose entity" as such term is used
in SFAS 140 and any successor rule thereto and its power and authority as stated
in Section 2.11 of this Agreement shall be limited in accordance with paragraph
35 or SFAS 140.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

     SECTION 3.01. Servicer to Service Mortgage Loans

     For and on behalf of the Certificateholders, the Servicer shall service and
administer the Mortgage Loans in accordance with Accepted Servicing Practices.
In connection with such servicing and administration, the Servicer shall have
full power and authority, acting alone and/or through subservicers as provided
in Section 3.02 hereof, to do or cause to be done any and all things that it may
deem necessary or desirable in connection with such servicing and
administration, including but not limited to, the power and authority, subject
to the terms hereof (i) to execute and deliver, on behalf of the

                                      -80-

<PAGE>

Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided in this Agreement), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds and (iv) subject to Section 3.12(a), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that, subject to Section 6.03, the
Servicer shall not take any action that is inconsistent with or prejudices the
interests of the Issuing Entity or the Certificateholders in any Mortgage Loan
serviced by it under this Agreement or the rights and interests of the other
parties to this Agreement except as otherwise required by this Agreement or by
law. Notwithstanding anything in this Agreement to the contrary, the Servicer
shall not make or permit any modification, waiver or amendment of any term of
any Mortgage Loan which would cause any of the REMICs provided for herein to
fail to qualify as a REMIC or result in the imposition of any tax under Section
860G(a) or 860G(d) of the Code. The Servicer shall represent and protect the
interest of the Trust Fund in the same manner as it currently protects its own
interest in mortgage loans in its own portfolio in any claim, proceeding or
litigation regarding a Mortgage Loan, but in any case not in any manner that is
a lesser standard than that provided in the first sentence of this Section 3.01.
Without limiting the generality of the foregoing, the Servicer, in its own name
or in the name of the Depositor and the Trustee, is hereby authorized and
empowered by the Depositor and the Trustee, when the Servicer believes it
appropriate in its reasonable judgment, to execute and deliver, on behalf of the
Trustee, the Depositor, the Certificateholders or any of them, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge, subordinations and all other comparable instruments, with respect to
the Mortgage Loans, and with respect to the Mortgaged Properties held for the
benefit of the Certificateholders. The Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery by
any or all of them as are necessary or appropriate to enable the Servicer to
service and administer the Mortgage Loans, to the extent that the Servicer is
not permitted to execute and deliver such documents pursuant to the preceding
sentence. Upon receipt of such documents, the Depositor and/or the Trustee shall
execute such documents and deliver them to the Servicer. For purposes of this
Section 3.01, the Trustee hereby grants to the Servicer a limited power of
attorney to execute and file any and all documents necessary to fulfill the
obligations of the Servicer under this Section 3.01.

     Upon request of the Servicer, the Trustee shall furnish the Servicer with
any powers of attorney and other documents in form as provided to it necessary
or appropriate to enable the Servicer to service and administer the Mortgage
Loans. The Trustee shall not be responsible for and the Servicer shall indemnify
the Trustee for any action taken by the Servicer pursuant to the application of
any power of attorney. Notwithstanding anything contained herein to the
contrary, the Servicer shall not without the Trustee's written consent, hire or
procure counsel to represent the Trustee without indicating its representative
capacity.

     The Servicer shall not be required to make any Servicing Advance with
respect to a Mortgage Loan that is 150 days or more delinquent.

     The Servicer and the Trustee shall have at least 10 days' notice of the
issuance of any NIM Notes.

     The Servicer shall deliver a list of Servicing Officers and specimen
signatures to the Trustee by the Closing Date.

     The Servicer will transmit full-file credit reporting data for each
Mortgage Loan pursuant to Fannie Mae Guide Announcement 97-02 and for each
Mortgage Loan, the Servicer agrees that it shall

                                      -81-

<PAGE>

report one of the following statuses each month as follows: current, delinquent
(30-, 60-, 90-days, etc.), foreclosed or charged-off.

     The Servicer further is authorized and empowered by the Trustee, on behalf
of the Certificateholders and the Trustee, in its own name or in the name of the
Sub-Servicer, when the Servicer or the Sub-Servicer, as the case may be,
believes it is appropriate in its best judgment to register any Mortgage Loan on
the MERS System, or cause the removal from the registration of any Mortgage Loan
on the MERS System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with respect to such assignment or re-recording of
a Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns. Any reasonable expenses incurred in connection with the
actions described in the preceding sentence or as a result of MERS discontinuing
or becoming unable to continue operations in connection with the MERS System,
shall be subject to withdrawal by the Servicer from the Collection Account
(provided that such expenses constitute "unanticipated expenses" within the
meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii)).

     With respect to any Mortgage Loan, the Servicer may consent to the
refinancing of the prior senior lien relating to such Mortgage Loan, provided
that the following requirements are met:

          (a) the resulting Combined Loan-to-Value Ratio of such Mortgage Loan
is no higher than the Combined Loan-to-Value Ratio prior to such refinancing;

          (b) the interest rate for the loan evidencing the refinanced senior
lien is no more than 2.0% higher than the interest rate on the loan evidencing
the existing senior lien immediately prior to the date of such refinancing; and

          (c) the loan evidencing the refinanced senior lien is not subject to
negative amortization.

     SECTION 3.02. Servicing and Subservicing; Enforcement of the Obligations of
Servicer

          (a) The Servicer may arrange for the subservicing of any Mortgage Loan
by a subservicer, which may be an affiliate, pursuant to a subservicing
agreement (each, a "Subservicing Agreement"); provided, however, that (i) such
subservicing arrangement and the terms of the related Subservicing Agreement
must provide for the servicing of such Mortgage Loans in a manner consistent
with the servicing arrangements contemplated hereunder and (ii) that such
agreement would not result in a withdrawal or downgrading by any Rating Agency
of the ratings of any Certificates or any of the NIM Notes evidenced by a letter
to that effect delivered by each Rating Agency to the Depositor. Notwithstanding
the provisions of any Subservicing Agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Servicer and a
subservicer or reference to actions taken through a subservicer or otherwise,
the Servicer shall remain obligated and liable to the Depositor, the Trustee and
the Certificateholders for the servicing and administration of the Mortgage
Loans in accordance with the provisions of this Agreement without diminution of
such obligation or liability by virtue of such Subservicing Agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Mortgage Loans. Every Subservicing
Agreement entered into by the Servicer shall contain a provision giving any
successor servicer the option to terminate such agreement in the event a
successor servicer is appointed. All actions of the each subservicer performed
pursuant to the

                                      -82-

<PAGE>

related Subservicing Agreement shall be performed as an agent of the Servicer
with the same force and effect as if performed directly by the Servicer. The
Servicer shall deliver to the Trustee copies of all Subservicing Agreements. The
Trustee shall have no obligations, duties or liabilities with respect to a
subservicer, including, without limitation, any obligation, duty or liability to
monitor such subservicer or to pay a Subservicer's fees and expenses.

          (b) For purposes of this Agreement, the Servicer shall be deemed to
have received any collections, recoveries or payments with respect to the
Mortgage Loans that are received by a subservicer regardless of whether such
payments are remitted by the subservicer to the Servicer.

          (c) The Servicer shall not permit a Subservicer to perform any
servicing responsibilities hereunder with respect to the Mortgage Loans unless
that Subservicer first agrees in writing with the Servicer to deliver an
Assessment of Compliance and an Accountant's Attestation in such manner and at
such times that permits that Servicer to comply with Section 3.17 of this
Agreement.

          (d) The Servicer may enter into a special servicing advisory agreement
with a holder of the Class R Certificate and/or one or more other class of
subordinated certificates issued by the Issuing Entity or of a net interest
margin trust holding certificates issued by the Issuing Entity and/or an advisor
designated by the holder of the Class R Certificate. Pursuant to such agreement,
the Servicer may provide such holder or advisor, in its capacity as special
servicing advisor, with loan-level information with respect to the Mortgage
Loans, and the holder of the Class R Certificate or the special servicing
advisor designated by the holder of the Class R Certificate may advise the
Servicer with respect to the commencement of foreclosure proceedings or other
actions to liquidate such Mortgage Loans and/or any other efforts to maximize
recoveries with respect to such Mortgage Loans.

     SECTION 3.03. Rights of the Depositor and the Trustee in Respect of the
Servicer

     Neither the Trustee nor the Depositor shall have any responsibility or
liability for any action or failure to act by the Servicer, and neither of them
is obligated to supervise the performance of the Servicer hereunder or
otherwise.

     SECTION 3.04. Trustee to Act as Servicer

     Subject to Sections 6.04 and 7.02, in the event that the Servicer shall for
any reason no longer be the servicer hereunder (including by reason of an Event
of Default), the Trustee or its designee shall, within a period of time not to
exceed ninety (90) days from the date of notice of termination or resignation,
thereupon assume all of the rights and obligations of the Servicer hereunder
arising thereafter (except that the Trustee shall not be (i) liable for losses
arising out of any acts or omissions of the predecessor servicer hereunder, (ii)
obligated to make Advances or Servicing Advances if it is prohibited from doing
so by applicable law, (iii) obligated to effectuate repurchases or substitutions
of Mortgage Loans hereunder, including pursuant to Section 2.02, 2.03 or
2.05hereof, (iv) responsible for any expenses of the Servicer pursuant to
Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.04 or the first paragraph of Section
6.02 hereof; provided, however that the Trustee (subject to clause (ii) above)
or its designee, in its capacity as the successor servicer, shall immediately
assume the terminated or resigning Servicer's obligation to make Advances and
Servicing Advances). No such termination or resignation shall affect any
obligation of the Servicer to pay amounts owed under this Agreement and to
perform its duties under this Agreement until its successor assumes all of its
rights and obligations hereunder. If the Servicer shall for any reason no

                                      -83-

<PAGE>

longer be a servicer (including by reason of any Event of Default), the Trustee
(or any other successor servicer) may, at its option, succeed to any rights and
obligations of the Servicer under any subservicing agreement in accordance with
the terms thereof; provided, however, that the Trustee (or any other successor
servicer) shall not incur any liability or have any obligations in its capacity
as servicer under a subservicing agreement arising prior to the date of such
succession unless it expressly elects to succeed to the rights and obligations
of the Servicer thereunder; and the Servicer shall not thereby be relieved of
any liability or obligations under the subservicing agreement arising prior to
the date of such succession. To the extent any costs or expenses, including
without limitation, Servicing Transfer Costs incurred by the Trustee in
connection with this Section 3.04 or Section 7.02, are not paid by the Servicer
pursuant to this Agreement within thirty (30) days of the date of the Trustee's
invoice thereof, such amounts shall be payable out of the Certificate Account;
provided that if the Servicer has been terminated by reason of an Event of
Default, the terminated servicer shall reimburse the Issuing Entity for any such
expense incurred by the Issuing Entity upon receipt of a reasonably detailed
invoice evidencing such expenses. If the Trustee is unwilling or unable to act
as servicer, the Trustee shall seek to appoint a successor servicer that is
eligible in accordance with the criteria specified in this Agreement.

     The Servicer shall, upon request of the Trustee, but at the expense of the
Servicer if the Servicer has been terminated by reason of an Event of Default,
deliver to the assuming party all documents and records relating to each
subservicing agreement and the Mortgage Loans then being serviced and otherwise
use its best efforts to effect the orderly and efficient transfer of the
subservicing agreement to the assuming party.

     SECTION 3.05. Collection of Mortgage Loan Payments; Collection Account;
Certificate Account

          (a) The Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing, the Servicer may in
its discretion (i) waive any late payment charge or, if applicable, any default
interest charge, or (ii) subject to Section 3.01, extend the due dates for
payments due on a Mortgage Note for a period not greater than 180 days;
provided, however, that any extension pursuant to clause (ii) above shall not
affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below. In the event of any such
arrangement pursuant to clause (ii) above, subject to Section 4.01, the Servicer
shall make any Advances on the related Mortgage Loan during the scheduled period
in accordance with the amortization schedule of such Mortgage Loan without
modification thereof by reason of such arrangements. Notwithstanding the
foregoing, in the event that any Mortgage Loan is in default or, in the judgment
of the Servicer, such default is reasonably foreseeable, the Servicer,
consistent with the standards set forth in Section 3.01, may also waive, modify
or vary any term of such Mortgage Loan (including modifications that would
change the Mortgage Rate, forgive the payment of principal or interest or extend
the final maturity date of such Mortgage Loan), accept payment from the related
Mortgagor of an amount less than the Stated Principal Balance in final
satisfaction of such Mortgage Loan, or consent to the postponement of strict
compliance with any such term or otherwise grant indulgence to any Mortgagor
(any and all such waivers, modifications, variances, forgiveness of principal or
interest, postponements, or indulgences collectively referred to herein as
"forbearance"), provided, however, that in determining which course of action
permitted by this sentence it shall pursue, the Servicer shall adhere to the
standards of Section 3.01. The Servicer's analysis supporting any forbearance
and the conclusion that any forbearance meets the standards of Section 3.01
shall be reflected in writing in the Mortgage File.

                                      -84-

<PAGE>

          (b) The Servicer will not waive any Prepayment Charge or portion
thereof unless, (i) the enforceability thereof shall have been limited by
bankruptcy, insolvency, moratorium, receivership or other similar laws relating
to creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) the Servicer has not
been provided with information sufficient to enable it to collect the Prepayment
Charge, or (iv) in the Servicer's reasonable judgment as described in Section
3.01 hereof, (x) such waiver relates to a default or a reasonably foreseeable
default, (y) such waiver would maximize recovery of total proceeds taking into
account the value of such Prepayment Charge and related Mortgage Loan and (z)
doing so is standard and customary in servicing similar Mortgage Loans
(including any waiver of a Prepayment Charge in connection with a refinancing of
a Mortgage Loan that is related to a default or a reasonably foreseeable
default), or (v) the collection of the Prepayment Charge or of a similar type of
prepayment premium would be considered "predatory" or "illegal" pursuant to
written guidance published by any applicable federal, state or local regulatory
authority having jurisdiction over such matters or has been challenged by any
such authority, or (vi) only to the extent that the Depositor has notified the
Servicer that there are no NIM Notes outstanding, there is a certified class
action in which a similar type of prepayment premium is being challenged. Except
as provided in the preceding sentence, in no event will the Servicer waive a
Prepayment Charge in connection with a refinancing of a Mortgage Loan that is
not related to a default or a reasonably foreseeable default. If the Servicer
waives or does not collect all or a portion of a Prepayment Charge relating to a
Principal Prepayment in full or in part due to any action or omission of the
Servicer, other than as provided above, the Servicer shall deposit the amount of
such Prepayment Charge (or such portion thereof as had been waived for deposit)
into the Collection Account for distribution in accordance with the terms of
this Agreement.

          (c) The Servicer shall not be required to institute or join in
litigation with respect to collection of any payment (whether under a Mortgage,
Mortgage Note or otherwise or against any public or governmental authority with
respect to a taking or condemnation) if it reasonably believes that enforcing
the provision of the Mortgage or other instrument pursuant to which such payment
is required is prohibited by applicable law.

          (d) The Servicer shall establish and initially maintain, on behalf of
Trustee for the benefit of the Certificateholders, a Collection Account. The
Servicer shall deposit into such Collection Account daily, within two (2)
Business Days of receipt thereof, in immediately available funds, the following
payments and collections received or made by it on and after the Cut-off Date
with respect to the Mortgage Loans:

          (i) all payments on account of principal, including Principal
     Prepayments, on the Mortgage Loans, other than principal due on the
     Mortgage Loans on or prior to the Cut-off Date;

          (ii) all payments on account of interest on the Mortgage Loans net of
     the Servicing Fee permitted under Section 3.15, other than (x) interest due
     on the Mortgage Loans on or prior to the Cut-off Date and (y) Prepayment
     Interest Excess;

          (iii) all Liquidation Proceeds, other than proceeds to be applied to
     the restoration or repair of the Mortgaged Property or released to either
     the Mortgagor or the holder of a senior lien on the Mortgaged Property in
     accordance with the Servicer's normal servicing procedures;

          (iv) all Subsequent Recoveries;

                                      -85-

<PAGE>

          (v) all Compensating Interest;

          (vi) any amount required to be deposited by the Servicer pursuant to
     Section 3.05(g) in connection with any losses on Permitted Investments;

          (vii) any amounts required to be deposited by the Servicer pursuant to
     Section 3.10 hereof;

          (viii) all Advances made by the Servicer pursuant to Section 4.01;

          (ix) all Prepayment Charges; and

          (x) any other amounts required to be deposited hereunder.

     The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, late payment charges,
insufficient funds charges and payments in the nature of assumption fees (i.e.
fees related to the assumption of a Mortgage Loan upon the purchase of the
related Mortgaged Property and other similar ancillary fees (other than
Prepayment Charges) if collected, and any Prepayment Interest Excess need not be
remitted by the Servicer. Rather, such fees and charges may be retained by the
Servicer as additional servicing compensation. In the event that the Servicer
shall remit any amount not required to be remitted and not otherwise subject to
withdrawal pursuant to Section 3.08 hereof, it may at any time withdraw or
direct the Trustee, or such other institution maintaining the Collection
Account, to withdraw such amount from the Collection Account, any provision
herein to the contrary notwithstanding. The Servicer shall maintain adequate
records with respect to all withdrawals made pursuant to this Section. All funds
deposited in the Collection Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08. In no event
shall the Trustee incur liability for withdrawals from the Collection Account at
the direction of the Servicer.

     The Servicer shall give notice to the Trustee of the location of the
Collection Account maintained by it when established and prior to any change
thereof. Not later than twenty days after each Distribution Date, the Servicer
shall forward to the Trustee and the Depositor the most current available bank
statement for the Collection Account. Copies of such statement shall be provided
by the Trustee to any Certificateholder and to any Person identified to the
Trustee as a prospective transferee of a Certificate, upon request at the
expense of the requesting party, provided such statement is delivered by the
Servicer to the Trustee.

          (e) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Certificate Account. The Trustee shall, promptly upon
receipt, deposit or cause to be deposited in the Certificate Account and retain
therein the following:

          (i) the aggregate amount withdrawn by the Servicer from the Collection
     Account for deposit in the Certificate Account;

          (ii) the Purchase Price and any Substitution Adjustment Amount;

          (iii) any amount required to be deposited by the Trustee pursuant to
     Section 3.05(g) in connection with any losses on Permitted Investments; and

                                      -86-

<PAGE>

          (iv) the Optional Termination Amount paid by the winning bidder at the
     Auction or by the Servicer pursuant to Section 9.01.

     Any amounts received by the Trustee prior to 1:00 p.m. New York City time
(or such earlier deadline for investment in the Permitted Investments designated
by the Trustee) which are required to be deposited in the Certificate Account by
the Servicer may be invested in Permitted Investments on the Business Day on
which they were received. The foregoing requirements for remittance by the
Servicer and deposit by the Servicer into the Certificate Account shall be
exclusive. If the Servicer fails to remit any funds due by the time designated
herein, the Servicer shall pay to the Trustee, for its own account, interest
accrued on such funds at the prime rate as set forth in The Wall Street Journal
from and including the applicable due date, to but excluding the day such funds
are paid to the Trustee. In the event that the Servicer shall remit any amount
not required to be remitted and not otherwise subject to withdrawal pursuant to
Section 3.08 hereof, it may at any time withdraw such amount from the
Certificate Account, any provision herein to the contrary notwithstanding. All
funds deposited in the Certificate Account shall be held by the Trustee in trust
for the Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.08. In no event shall the Trustee incur
liability for withdrawals from the Certificate Account at the direction of the
Servicer. The Trustee shall give notice to the Servicer of the location of the
Certificate Account maintained by it when established and prior to any change
thereof.

          (f) Each institution that maintains the Collection Account shall, and
each institution that maintains the Certificate Account may but shall not be
required to, invest the funds in each such account, as directed by the Servicer
or the Trustee, as applicable, in writing, in Permitted Investments, which shall
mature not later than (i) in the case of the Collection Account, the Business
Day preceding the Servicer Remittance Date (except that if such Permitted
Investment is an obligation of the institution that maintains such Collection
Account or is otherwise immediately available, then such Permitted Investment
shall mature not later than the Servicer Remittance Date) and (ii) in the case
of the Certificate Account, the Business Day immediately preceding the first
Distribution Date that follows the date of such investment (except that if such
Permitted Investment is an obligation of the institution that maintains such
Certificate Account or is otherwise immediately available, then such Permitted
Investment shall mature not later than such Distribution Date) and, in each
case, shall not be sold or disposed of prior to its maturity. All such Permitted
Investments shall be made in the name of the Trustee for the benefit of the
Certificateholders. All income and gain net of any losses realized from amounts
on deposit in the Collection Account shall be for the benefit of the Servicer as
servicing compensation and shall be remitted to it monthly as provided herein.
The amount of any losses incurred in the Collection Account in respect of any
such investments shall be deposited by the Servicer in the Collection Account
out of the Servicer's own funds immediately as realized. All income and gain net
of any losses realized from amounts on deposit in the Certificate Account shall
be for the benefit of the Trustee and shall be remitted to or withdrawn by it
monthly as provided herein. The amount of any losses incurred in the Certificate
Account in respect of any such investments shall be deposited by the Trustee in
the Certificate Account out of the Trustee's own funds immediately as realized.

     SECTION 3.06. Collection of Taxes, Assessments and Similar Items; Escrow
Accounts

     To the extent required by the related Mortgage Note, the Servicer shall
establish and maintain one or more accounts (each, an "Escrow Account") and
deposit and retain therein all collections from the Mortgagors (or advances by
the Servicer) for the payment of taxes, assessments, hazard insurance

                                      -87-

<PAGE>

premiums or comparable items for the account of the Mortgagors. Nothing herein
shall require the Servicer to compel a Mortgagor to establish an Escrow Account
in violation of applicable law.

     Withdrawals of amounts so collected from the Escrow Accounts may be made
only to effect timely payment of taxes, assessments, hazard insurance premiums,
condominium or PUD association dues, or comparable items, to reimburse the
Servicer out of related collections for any payments made pursuant to Sections
3.01 hereof (with respect to taxes and assessments and insurance premiums) and
3.10 hereof (with respect to hazard insurance), to refund to any Mortgagors any
sums as may be determined to be overages, to pay interest, if required by law or
the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in
the Escrow Account or to clear and terminate the Escrow Account at the
termination of this Agreement in accordance with Section 9.01 hereof. The Escrow
Accounts shall not be a part of the Trust Fund.

     SECTION 3.07. Access to Certain Documentation and Information Regarding the
Mortgage Loans

     Upon reasonable advance notice in writing if required by federal
regulation, the Servicer will provide to each Certificateholder that is a
savings and loan association, bank or insurance company certain reports and
reasonable access to information and documentation regarding the Mortgage Loans
sufficient to permit such Certificateholder to comply with applicable
regulations of the OTS or other regulatory authorities with respect to
investment in the Certificates; provided, that the Servicer shall be entitled to
be reimbursed by each such Certificateholder for actual expenses incurred by the
Servicer in providing such reports and access.

     The Servicer may from time to time provide the Depositor, and any Person
designated by the Depositor, with reports and information regarding the Mortgage
Loans, including without limitation, information requested by the Depositor or
an originator of the Mortgage Loans for required institutional risk control. In
addition, subject to limitations of applicable privacy laws, the Servicer may
make public information regarding performance of the Mortgage Loans.

     SECTION 3.08. Permitted Withdrawals from the Collection Account and
Certificate Account

          (a) The Servicer may from time to time, make withdrawals from the
Collection Account for the following purposes:

          (i) to pay to the Servicer (to the extent not previously paid to or
     withheld by the Servicer), as servicing compensation in accordance with
     Section 3.15, that portion of any payment of interest that equals the
     Servicing Fee for the period with respect to which such interest payment
     was made, and, as additional servicing compensation, those other amounts
     set forth in Section 3.15;

          (ii) to reimburse the Servicer (or the Trustee as successor servicer)
     for Advances made by it (or to reimburse the Advance Financing Person for
     Advances made by it) with respect to the Mortgage Loans, such right of
     reimbursement pursuant to this subclause (ii) being limited to amounts
     received on particular Mortgage Loan(s) (including, for this purpose,
     Liquidation Proceeds) that represent late recoveries of payments of
     principal and/or interest on such particular Mortgage Loan(s) in respect of
     which any such Advance was made;

                                      -88-
<PAGE>

          (iii) to reimburse the Servicer for any Non-Recoverable Advance
     previously made and any Non-Recoverable Servicing Advances previously made
     to the extent that, in the case of Non-Recoverable Servicing Advances,
     reimbursement therefor constitutes "unanticipated expenses" within the
     meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii);

          (iv) to pay to the Servicer earnings on or investment income with
     respect to funds in or credited to the Collection Account;

          (v) to reimburse the Servicer from Insurance Proceeds for Insured
     Expenses covered by the related Insurance Policy;

          (vi) [reserved];

          (vii) to pay the Servicer (or the Trustee as successor servicer) any
     unpaid Servicing Fees and to reimburse it for any unreimbursed Servicing
     Advances (to the extent that reimbursement for Servicing Advances would
     constitute an "unanticipated expense" within the meaning of Treasury
     Regulation Section 1.860G-1(b)(3)(ii)), the Servicer's right to
     reimbursement of Servicing Advances pursuant to this subclause (vii) with
     respect to any Mortgage Loan being limited to amounts received on
     particular Mortgage Loan(s)(including, for this purpose, Liquidation
     Proceeds and purchase and repurchase proceeds and including any Subsequent
     Recoveries related to any Liquidated Loan) that represent late recoveries
     of the payments for which such advances were made pursuant to Section 3.01
     or Section 3.06;

          (viii) to pay to the Depositor or the Servicer, as applicable, with
     respect to each Mortgage Loan or property acquired in respect thereof that
     has been purchased pursuant to Section 2.02, 2.03 or 3.12, all amounts
     received thereon and not taken into account in determining the related
     Stated Principal Balance of such repurchased Mortgage Loan;

          (ix) to reimburse the Servicer, the Trustee or the Depositor for
     expenses incurred by any of them in connection with the Mortgage Loans or
     the Certificates and reimbursable pursuant to Section 3.04, Section 3.25 or
     Section 6.03 hereof provided that reimbursement therefor would constitute
     "unanticipated" expenses within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii);

          (x) to reimburse the Trustee for enforcement expenses reasonably
     incurred in respect of a breach or defect giving rise to the purchase
     obligation in Section 2.03 that were incurred in the Purchase Price of the
     Mortgage Loans including any expenses arising out of the enforcement of the
     purchase obligation; provided that any such expenses will be reimbursable
     under this subclause (x) only to the extent that such expenses would
     constitute "unanticipated expenses" within the meaning of Treasury
     Regulation Section 1.860G-1(b)(3)(ii) if paid by one of the REMICs provided
     for herein;

          (xi) to pay the Servicer any unpaid Servicing Fees for any Mortgage
     Loan upon such Mortgage Loan being charged off and upon termination of the
     obligations of the Servicer;

          (xii) to withdraw pursuant to Section 3.05 any amount deposited in the
     Collection Account and not required to be deposited therein; and

                                      -89-

<PAGE>

          (xiii) to clear and terminate the Collection Account upon termination
     of this Agreement pursuant to Section 9.01 hereof.

     In addition, the Servicer will use commercially reasonable efforts to cause
to be withdrawn from the Collection Account no later than 2:30 p.m. Eastern
Time, but in any case no later than 4:00 p.m. Eastern Time on the Servicer
Remittance Date, the Interest Funds and the Principal Funds (for this purpose
only, neither Interest Funds nor Principal Funds shall include a deduction for
any amount reimbursable to the Trustee unless such amounts have actually been
reimbursed from such funds at the discretion of the Servicer), to the extent on
deposit, and such amount shall be deposited in the Certificate Account;
provided, however, if the Trustee does not receive such Interest Funds and
Principal Funds on the Servicer Remittance Date, the Servicer shall pay, out of
its own funds, interest on such amount at a rate equal to the "prime rate" as
published by The Wall Street Journal at such time for each date or part thereof.

     The Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from
the Collection Account.

     The Servicer shall provide written notification to the Trustee on or prior
to the next succeeding Servicer Remittance Date upon making any withdrawals from
the Collection Account pursuant to subclauses (iii) and (vii) above.

     Unless otherwise specified, any amounts reimbursable to the Servicer or the
Trustee from amounts on deposit in the Collection Account or the Certificate
Accounts shall be deemed to come from first, Interest Funds, and thereafter,
Principal Funds for the related Distribution Date.

          (b) The Trustee shall withdraw funds from the Certificate Account for
distribution to the Certificateholders in the manner specified in this Agreement
(and shall withhold from the amounts so withdrawn, the amount of any taxes that
it is authorized to retain pursuant to this Agreement). In addition, prior to
making such distributions to the Certificateholders, the Trustee may from time
to time make withdrawals from the Certificate Account for the following
purposes:

          (i) to withdraw pursuant to Section 3.05 any amount deposited in the
     Certificate Account and not required to be deposited therein;

          (ii) to clear and terminate the Certificate Account upon termination
     of the Agreement pursuant to Section 9.01 hereof (after paying all amounts
     necessary to the Trustee or the Servicer in connection with any such
     termination);

          (iii) to pay to the Trustee for any fees, expenses and indemnification
     reimbursable pursuant to this Agreement, including without limitation
     Sections 3.04, 6.03, 8.05 and 8.06 hereof; and

          (iv) to pay to the Trustee earnings on or investment income with
     respect to funds in or credited to the Certificate Account.

     SECTION 3.09. [RESERVED]

     SECTION 3.10. Maintenance of Hazard Insurance

                                      -90-

<PAGE>

     The Servicer shall cause to be maintained, for each first lien Mortgage
Loan, hazard insurance with extended coverage in an amount, to the extent
permitted by applicable law, that is at least equal to the lesser of (i) the
estimated replacement value of the improvements that are part of such Mortgaged
Property which may be the last known coverage, or (ii) the greater of (a) the
outstanding principal balance of the Mortgage Loan and (b) an amount such that
the proceeds of such policy shall be sufficient to prevent the related Mortgagor
and/or mortgagee from becoming a co-insurer or (iii) the amount required under
applicable HUD/FHA regulations. Each such policy of standard hazard insurance
shall contain, or have an accompanying endorsement that contains, a standard
mortgagee clause. The Servicer shall also cause flood insurance to be maintained
on property acquired upon foreclosure or deed in lieu of foreclosure of any
Mortgage Loan, to the extent required under the standards described below.
Pursuant to Section 3.05 hereof, any amounts collected by the Servicer under any
such policies (other than the amounts to be applied to the restoration or repair
of the related Mortgaged Property or property thus acquired or amounts released
to the Mortgagor in accordance with the Servicer's normal servicing procedures)
shall be deposited in the Collection Account. Any cost incurred by the Servicer
in maintaining any such insurance shall not, for the purpose of calculating
monthly distributions to the Certificateholders or remittances to the Trustee
for their benefit, be added to the principal balance of the Mortgage Loan,
notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall
be recoverable by the Servicer out of late payments by the related Mortgagor or
out of Liquidation Proceeds to the extent and as otherwise permitted by Section
3.08 hereof. It is understood and agreed that no earthquake or other additional
insurance is to be required of any Mortgagor or maintained on property acquired
in respect of a Mortgage other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance. If a first lien Mortgaged Property is located at the time
of origination of the Mortgage Loan in a federally designated special flood
hazard area and such area is participating in the national flood insurance
program, the Servicer shall cause flood insurance to be maintained with respect
to such Mortgage Loan. Such flood insurance shall be in an amount equal to the
lesser of (i) the outstanding principal balance of the related Mortgage Loan,
(ii) the estimated replacement value of the improvements that are part of such
Mortgaged Property which may be the last known coverage, or (iii) the maximum
amount of such insurance available for the related Mortgaged Property under the
Flood Disaster Protection Act of 1973, as amended.

     In the event that the Servicer shall obtain and maintain a blanket policy
insuring against hazard losses on all of the Mortgage Loans, it shall
conclusively be deemed to have satisfied its obligations as set forth in the
first sentence of this Section 3.10, it being understood and agreed that such
policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Servicer shall, in the event that there
shall not have been maintained on the related Mortgaged Property a policy
complying with the first sentence of this Section 3.10, and there shall have
been a loss that would have been covered by such policy, deposit in the
Collection Account the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as servicer
of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the
Depositor and the Trustee for the benefit of the Certificateholders, claims
under any such blanket policy.

     SECTION 3.11.Enforcement of Due-On-Sale Clauses; Assumption Agreements

     When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, except as set forth below, to the extent it has
knowledge of such conveyance or prospective conveyance, exercise its rights to
accelerate the maturity of the related Mortgage Loan under any "due-on-sale"
clause contained in the related Mortgage or Mortgage Note; provided, however,
that the Servicer

                                      -91-
<PAGE>

shall not exercise any such right if the "due-on-sale" clause, in the reasonable
belief of the Servicer, is not enforceable under applicable law or, if
consistent with applicable mortgage servicing practices, the Servicer reasonably
believes that collections and other recoveries in respect of such Mortgage Loans
would be maximized if the Mortgage Loans were not accelerated; provided,
further, that the Servicer shall not take any action in relation to the
enforcement of any "due-on-sale" clause that would adversely affect or
jeopardize coverage under any Required Insurance Policy. An Opinion of Counsel
at the expense of the Servicer (which expense shall constitute a Servicing
Advance) delivered to the Trustee and the Depositor shall conclusively establish
the reasonableness of the Servicer's belief that any "due-on-sale" clause is not
enforceable under applicable law. In such event, the Servicer shall make
reasonable efforts to enter into an assumption and modification agreement with
the Person to whom such property has been or is about to be conveyed, pursuant
to which such Person becomes liable under the Mortgage Note and, unless
prohibited by applicable law or the Mortgage, the Mortgagor remains liable
thereon. If the foregoing is not permitted under applicable law, the Servicer is
authorized to enter into a substitution of liability agreement with such Person,
pursuant to which the original Mortgagor is released from liability and such
Person is substituted as Mortgagor and becomes liable under the Note. In
addition to the foregoing, the Servicer shall not be required to enforce any
"due-on-sale" clause if in the reasonable judgment of the Servicer, entering
into an assumption and modification agreement with a Person to whom such
property shall be conveyed and releasing the original Mortgagor from liability
would be in the best interests of the Certificateholders. The Mortgage Loan, as
assumed, shall conform in all respects to the requirements, representations and
warranties of this Agreement. The Servicer shall notify the Trustee that any
such assumption or substitution agreement has been completed by forwarding to
the Trustee the original copy of such assumption or substitution agreement
(indicating the Mortgage File to which it relates), which copy shall be added by
the Trustee to the related Mortgage File and which shall, for all purposes, be
considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof. The Servicer shall be
responsible for recording any such assumption or substitution agreements. In
connection with any such assumption or substitution agreement, the Monthly
Payment on the related Mortgage Loan shall not be changed but shall remain as in
effect immediately prior to the assumption or substitution, the stated maturity
or outstanding principal amount of such Mortgage Loan shall not be changed nor
shall any required monthly payments of principal or interest be deferred or
forgiven. Any fee collected by the Servicer for consenting to any such
conveyance or entering into an assumption or substitution agreement shall be
retained by or paid to the Servicer as additional servicing compensation.

     Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

     SECTION 3.12.Realization Upon Defaulted Mortgage Loans; Determination of
Excess Proceeds; Special Loss Mitigation

          (a) The Servicer shall use reasonable efforts consistent with the
servicing standard set forth in Section 3.01 to foreclose upon or otherwise
comparably convert the ownership of properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of Delinquent payments. In connection
with such foreclosure or other conversion, the Servicer shall follow such
practices and procedures as it shall deem necessary or advisable and as shall be
normal and usual in its general mortgage servicing activities and the
requirements of the insurer under any Required Insurance Policy; provided,
however, that the Servicer

                                      -92-

<PAGE>

shall not be required to expend its own funds in connection with the restoration
of any property that shall have suffered damage due to an uninsured cause unless
it shall determine (i) that such restoration will increase the proceeds of
liquidation of the Mortgage Loan after reimbursement to itself of such expenses
and (ii) that such expenses will be recoverable to it through Liquidation
Proceeds (respecting which it shall have priority for purposes of withdrawals
from the Collection Account pursuant to Section 3.08 hereof). The Servicer shall
be responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 3.08 hereof. If the Servicer has knowledge that a
Mortgaged Property that the Servicer is contemplating acquiring in foreclosure
or by deed-in-lieu of foreclosure is located within a one-mile radius of any
site with environmental or hazardous waste risks known to the Servicer, the
Servicer will, prior to acquiring the Mortgaged Property, consider such risks
and only take action in accordance with Accepted Servicing Practices.

     With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee or its nominee. Pursuant to its efforts to sell
such REO Property, the Servicer shall either itself or through an agent selected
by the Servicer protect and conserve such REO Property in the same manner and to
such extent as is customary in the locality where such REO Property is located
and may, incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Servicer deems to
be in the best interest of the Servicer and the Certificateholders for the
period prior to the sale of such REO Property. The Servicer or an Affiliate
thereof may receive usual and customary real estate referral fees for real
estate brokers in connection with the listing and disposition of REO Property.
The Servicer shall prepare a statement with respect to each REO Property that
has been rented showing the aggregate rental income received and all expenses
incurred in connection with the management and maintenance of such REO Property
at such times as is necessary to enable the Servicer to comply with the
reporting requirements of the REMIC Provisions. The net monthly rental income,
if any, from such REO Property shall be deposited in the Collection Account no
later than the close of business on each Determination Date. The Servicer shall
perform the tax reporting and withholding related to foreclosures, abandonments
and cancellation of indebtedness income as specified by Sections 1445, 6050J and
6050P of the Code by preparing and filing such tax and information returns, as
may be required.

     In the event that the Issuing Entity acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
the expiration of three years from the end of the year of its acquisition by the
Issuing Entity or, at the expense of the Issuing Entity, obtain, in accordance
with applicable procedures for obtaining an automatic extension of the grace
period, more than sixty (60) days prior to the day on which such three-year
period would otherwise expire, an extension of the three-year grace period, in
which case such property must be disposed of prior to the end of such extension,
unless the Trustee shall have been supplied with an Opinion of Counsel (such
Opinion of Counsel not to be an expense of the Trustee), to the effect that the
holding by the Issuing Entity of such Mortgaged Property subsequent to such
three-year period or extension will not result in the imposition of taxes on
"prohibited transactions" of the Issuing Entity or any of the REMICs provided
for herein as defined in section 860F of the Code or cause any of the REMICs
provided for herein to fail to qualify as a REMIC at any time that any
Certificates are outstanding, in which case the Issuing Entity may continue to
hold such Mortgaged Property (subject to any conditions contained in such
Opinion of Counsel). Notwithstanding any other provision of this Agreement, no
Mortgaged Property acquired by the Issuing Entity shall be held, rented (or
allowed to continue to be rented) or otherwise used for the production of income
by or on behalf of the Issuing Entity in such a manner or pursuant to any terms
that would (i) cause such Mortgaged Property to

                                      -93-

<PAGE>

fail to qualify as "foreclosure property" within the meaning of section
860G(a)(8) of the Code or (ii) subject the Issuing Entity or any REMIC provided
for herein to the imposition of any federal, state or local income taxes on the
income earned from such Mortgaged Property under section 860G(c) of the Code or
otherwise, unless the Servicer or the Depositor has agreed to indemnify and hold
harmless the Trustee and the Issuing Entity with respect to the imposition of
any such taxes. The Servicer shall have no liability for any losses resulting
from a foreclosure on a second lien Mortgage Loan in connection with the
foreclosure of the related first lien mortgage loan that is not a Mortgage Loan
if the Servicer does not receive notice of such foreclosure action.

     The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of such
foreclosure would exceed the costs and expenses of bringing such a proceeding.
The income earned from the management of any Mortgaged Properties acquired
through foreclosure or other judicial proceeding, net of reimbursement to the
Servicer for expenses incurred (including any property or other taxes) in
connection with such management and net of unreimbursed Servicing Fees,
Advances, Servicing Advances and any management fee paid or to be paid with
respect to the management of such Mortgaged Property, shall be applied to the
payment of principal of, and interest on, the related defaulted Mortgage Loans
(with interest accruing as though such Mortgage Loans were still current) and
all such income shall be deemed, for all purposes in this Agreement, to be
payments on account of principal and interest on the related Mortgage Notes and
shall be deposited into the Collection Account. To the extent the income
received during a Prepayment Period is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Rate on the
related Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

     The Liquidation Proceeds from any liquidation of a Mortgage Loan, net of
any payment to the Servicer as provided above, shall be deposited in the
Collection Account on the next succeeding Determination Date following receipt
thereof for distribution on the related Distribution Date.

     The proceeds of any Liquidated Loan, as well as any recovery resulting from
a partial collection of Liquidation Proceeds, will be applied as between the
parties in the following order of priority: first, to reimburse the Servicer for
any related unreimbursed Servicing Advances and unpaid Servicing Fees, pursuant
to Section 3.08(a)(vii) or this Section 3.12; second, to reimburse the Servicer
for any unreimbursed Advances, pursuant to Section 3.08(a)(ii) or this Section
3.12; third, to accrued and unpaid interest (to the extent no Advance has been
made for such amount) on the Mortgage Loan, at the applicable Net Mortgage Rate
to the Due Date occurring in the month in which such amounts are required to be
distributed; fourth, as a recovery of principal of the Mortgage Loan; and fifth,
to any prepayment charges.

     The proceeds of any net income from an REO Property will be applied as
between the parties in the following order of priority: first, to reimburse the
Servicer for any related unreimbursed Servicing Advances and unpaid Servicing
Fees, pursuant to Section 3.08(a)(vii) or this Section 3.12; second, to
reimburse the Servicer for any unreimbursed Advances, pursuant to Section
3.08(a)(ii) or this Section 3.12; third, as a recovery of principal; and fourth,
to accrued and unpaid interest (to the extent no Advance has been made for such
amount) on the related REO Property, at the applicable Net Mortgage Rate to the
Due Date occurring in the month in which such amounts are required to be
distributed.

          (b) On each Determination Date, the Servicer shall determine the
respective aggregate amounts of Excess Proceeds, if any, that occurred in the
related Prepayment Period.

                                      -94-

<PAGE>

          (c) [RESERVED]

          (d) With respect to such of the Mortgage Loans as come into and
continue in default, the Servicer will decide, in its reasonable business
judgment, whether to (i) foreclose upon the Mortgaged Properties securing those
Mortgage Loans pursuant to Section 3.12(a), (ii) write off the unpaid principal
balance of the Mortgage Loans as bad debt (provided that the Servicer has
determined that no net recovery is possible through foreclosure proceedings or
other liquidation of the related Mortgaged Property), (iii) take a deed in lieu
of foreclosure, (iv) accept a short sale or short refinance; (v) arrange for a
repayment plan or refinancing, or (vi) agree to a modification of such Mortgage
Loan. As to any Mortgage Loan that becomes 120 days delinquent, the Servicer
shall have obtained or shall obtain a broker's price opinion, the cost of which
will be reimbursable as a Servicing Advance. After obtaining the broker's price
opinion, the Servicer will determine, in its reasonable business judgment,
whether a net recovery is possible through foreclosure proceedings or other
liquidation of the related Mortgage Property. If the Servicer determines that no
such recovery is possible, it must charge off the related Mortgage Loan at the
time it becomes 180 days delinquent. Once a Mortgage Loan has been charged off,
the Servicer will discontinue making Advances, the Servicer will not be entitled
to future Servicing Fees (except as provided below) with respect to such
Mortgage Loan, and the Mortgage Loan will be treated as a Liquidated Mortgage
Loan. If the Servicer determines that such net recovery is possible through
foreclosure proceedings or other liquidation of the related Mortgaged Property
on a Mortgage Loan that becomes 180 days delinquent, the Servicer will continue
to be entitled to Servicing Fees, the Servicer need not charge off such Mortgage
Loan and may continue making Advances, and the Servicer will be required to
notify the Trustee of such decision.

          (e) Any Mortgage Loan that is charged off, pursuant to (d) above, may
continue to be serviced by the Servicer for the Certificateholders using
specialized collection procedures (including foreclosure, if appropriate). The
Servicer will be entitled to Servicing Fees and reimbursement of expenses in
connection with such Mortgage Loans after the date of charge off, only to the
extent of funds available from any recoveries on any such Mortgage Loans. Any
such Mortgage Loans serviced in accordance with the specialized collection
procedures shall be serviced for approximately six months. Any net recoveries
received on such Mortgage Loans during such six month period will be treated as
Subsequent Recoveries. On the date which is six months after the date on which
the Servicer begins servicing such Mortgage Loans using the specialized
collection procedures, unless specific net recoveries are anticipated by the
Servicer on a particular Mortgage Loan, such charged off loan will be released
to the majority holder of the Class C Certificates and thereafter, (i) the
majority holder of the Class C Certificates, as identified with contact
information in writing to the Servicer by the Depositor, will be entitled to any
amounts subsequently received in respect of any such released loans, subject to
the Servicer's fees described below, (ii) the majority holder of the Class C
Certificates may designate any servicer to service any such released loan, (iii)
the majority holder of the Class C Certificates may sell any such released loan
to a third party and (iv) to the extent the servicing of such charged off loan
is not transferred from the Servicer, the servicing of such charged off loan and
the fees therefor shall be governed by the most current servicing agreement
between the Servicer and the Sponsor.

     SECTION 3.13.Trustee to Cooperate; Release of Mortgage Files

     Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will promptly notify the Trustee or
its custodian by delivering a Request for Release substantially in the form of
Exhibit I. Upon receipt of a copy of such request, the Trustee or its custodian
shall promptly release

                                      -95-

<PAGE>

the related Mortgage File to the Servicer, the cost of which may be charged to
the Servicer by the Trustee, and the Servicer is authorized to cause the removal
from the registration on the MERS System of any such Mortgage if applicable, and
the Servicer, on behalf of the Trustee shall execute and deliver the request for
reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage together with the Mortgage
Note with written evidence of cancellation thereon. Expenses incurred in
connection with any instrument of satisfaction or deed of reconveyance shall be
chargeable to the Mortgagor to the extent permitted by law, and otherwise to the
Trust Fund to the extent such expenses constitute "unanticipated expenses"
within the meaning of Treasury Regulations Section 1.860G-(1)(b)(3)(ii). From
time to time and as shall be appropriate for the servicing or foreclosure of any
Mortgage Loan, including for collection under any policy of flood insurance, any
fidelity bond or errors or omissions policy, or for the purposes of effecting a
partial release of any Mortgaged Property from the lien of the Mortgage or the
making of any corrections to the Mortgage Note or the Mortgage or any of the
other documents included in the Mortgage File, the Trustee or its custodian
shall, upon delivery to the Trustee or its custodian of a Request for Release in
the form of Exhibit I signed by a Servicing Officer, release the Mortgage File
to the Servicer, and the cost of delivery of the Mortgage File may be charged to
the Servicer by the Trustee. Subject to the further limitations set forth below,
the Servicer shall cause the Mortgage File or documents so released to be
returned to the Trustee or its custodian when the need therefor by the Servicer
no longer exists, unless the Mortgage Loan is liquidated and the proceeds
thereof are deposited in the Collection Account.

     Each Request for Release may be delivered to the Trustee or its custodian
(i) via mail or courier, (ii) via facsimile or (iii) by such other means,
including, without limitation, electronic or computer readable medium, as the
Servicer and the Trustee or its custodian shall mutually agree. The Trustee or
its custodian shall release the related Mortgage File(s) within four Business
Days of receipt of a properly completed Request for Release pursuant to clauses
(i), (ii) or (iii) above. Receipt of a properly completed Request for Release
shall be authorization to the Trustee or its custodian to release such Mortgage
Files, provided the Trustee or its custodian has determined that such Request
for Release has been executed, with respect to clauses (i) or (ii) above, or
approved, with respect to clause (iii) above, by an authorized Servicing Officer
of the Servicer, and so long as the Trustee or its custodian complies with its
duties and obligations under this Agreement. If the Trustee or its custodian is
unable to release the Mortgage Files within the period previously specified, the
Trustee or its custodian shall immediately notify the Servicer indicating the
reason for such delay. The Servicer shall not pay penalties or damages due to
the Trustee's or its designee's negligent failure to release the related
Mortgage File or the Trustee's or its designee's negligent failure to execute
and release documents in a timely manner, and such amounts shall be Servicer
Advances.

     On each day that the Servicer remits to the Trustee or its custodian
Requests for Releases pursuant to clauses (ii) or (iii) above, the Servicer
shall also submit to the Trustee or its custodian a summary of the total number
of such Requests for Releases requested on such day by the same method as
described in such clauses (ii) and (iii) above.

     If the Servicer at any time seeks to initiate a foreclosure proceeding in
respect of any Mortgaged Property as authorized by this Agreement, the Servicer
may deliver or cause to be delivered to the Trustee for signature, or on behalf
of the Trustee execute, any court pleadings, requests for trustee's sale or
other documents necessary to effectuate such foreclosure or any legal action
brought to obtain judgment against the Mortgagor on the Mortgage Note or the
Mortgage or to obtain a deficiency judgment or to enforce any other remedies or
rights provided by the Mortgage Note or the Mortgage or otherwise available at
law or in equity. Notwithstanding the foregoing, the Servicer shall cause
possession of any Mortgage File or of

                                      -96-

<PAGE>

the documents therein that shall have been released by the Trustee to be
returned to the Trustee promptly after possession thereof shall have been
released by the Trustee unless (i) the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Collection Account, and the Servicer shall have delivered to the Trustee a
Request for Release in the form of Exhibit I or (ii) the Mortgage File or
document shall have been delivered to an attorney or to a public trustee or
other public official as required by law for purposes of initiating or pursuing
legal action or other proceedings for the foreclosure of the Mortgaged Property
and the Servicer shall have delivered to the Trustee an Officer's Certificate of
a Servicing Officer certifying as to the name and address of the Person to which
the Mortgage File or the documents therein were delivered and the purpose or
purposes of such delivery.

     SECTION 3.14. Documents, Records and Funds in Possession of Servicer to be
Held for the Trustee.

     All Mortgage Files and funds collected or held by, or under the control of,
the Servicer in respect of any Mortgage Loans, whether from the collection of
principal and interest payments or from Liquidation Proceeds, including but not
limited to, any funds on deposit in the Collection Account, shall be held by the
Servicer for and on behalf of the Trustee and shall be and remain the sole and
exclusive property of the Trust Fund, subject to the applicable provisions of
this Agreement. The Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Collection
Account, Certificate Account or in any Escrow Account, or any funds that
otherwise are or may become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy, writ
of attachment or other encumbrance, or assert by legal action or otherwise any
claim or right of set off against any Mortgage File or any funds collected on,
or in connection with, a Mortgage Loan, except, however, that the Servicer shall
be entitled to set off against and deduct from any such funds any amounts that
are properly due and payable to the Servicer under this Agreement.

     SECTION 3.15. Servicing Compensation

     As compensation for its activities hereunder, the Servicer shall be
entitled to retain or withdraw from the Collection Account out of each payment
of interest on a Mortgage Loan included in the Trust Fund an amount equal to
interest at the applicable Servicing Fee Rate on the Stated Principal Balance of
the related Mortgage Loan as of the immediately preceding Distribution Date.

     Additional servicing compensation in the form of any Excess Proceeds, late
payment fees, assumption fees (i.e. fees related to the assumption of a Mortgage
Loan upon the purchase of the related Mortgaged Property) and similar fees
payable by the Mortgagor, Prepayment Interest Excess, all income and gain net of
any losses realized from Permitted Investments in the Collection Account, and
any other benefits arising from the Collection Account and the Escrow Account
shall be retained by the Servicer to the extent not required to be deposited in
the Collection Account and the Escrow Account pursuant to Sections 3.05, 3.06 or
3.12(a) hereof. The Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder and shall not be
entitled to reimbursement therefor except as specifically provided in this
Agreement. In no event shall the Trustee be liable for any Servicing Fee or for
any differential between the Servicing Fee and the amount necessary to induce a
successor servicer to act as successor servicer under this Agreement.

     SECTION 3.16. Access to Certain Documentation

                                      -97-

<PAGE>

     The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of the Certificates and the examiners
and supervisory agents of the OTS, the FDIC and such other authorities, as
applicable, access to the documentation regarding the Mortgage Loans required by
applicable regulations of the OTS and the FDIC. Such access shall be afforded
without charge, but only upon reasonable and prior written request and during
normal business hours at the offices of the Servicer designated by it provided,
that the Servicer shall be entitled to be reimbursed by each such
Certificateholder for actual expenses incurred by the Servicer in providing such
reports and access. Nothing in this Section shall limit the obligation of the
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Mortgagors and the failure of the Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section.

     SECTION 3.17. Annual Statement as to Compliance

     Not later than (a) March 12 of each calendar year (other than the calendar
year during which the Closing Date occurs) or (b) with respect to any calendar
year during which an annual report on Form 10-K is not required to be filed
pursuant to Section 3.20 on behalf of the Issuing Entity, by April 15 of each
calendar year (or if such day is not a Business Day, the immediately succeeding
Business Day), the Servicer shall deliver to the Trustee and the Depositor, an
Officer's Certificate in the form attached hereto as Exhibit U stating, as to
each signatory thereof, that (i) a review of the activities of the Servicer
during the preceding calendar year and of the performance of the Servicer under
this Agreement has been made under such officer's supervision, and (ii) to the
best of such officer's knowledge, based on such review, such Servicer has
fulfilled all its obligations under this Agreement in all material respects
throughout such year or a portion thereof, or, if there has been a failure to
fulfill any such obligation in any material respect, specifying each such
failure known to such officer and the nature and status thereof. With respect to
any Subservicer that meets the criteria of Item 1108(a)(2)(i) through (iii) of
Regulation AB, the Servicer shall deliver, on behalf of that Subservicer, the
Officer's Certificate set forth in this Section 3.17 as and when required with
respect to such Subservicer.

     SECTION 3.18. Annual Independent Public Accountants' Servicing Statement;
Financial Statements

          (a) Not later than (i) March 12 of each calendar year (other than the
calendar year during which the Closing Date occurs) or (ii) with respect to any
calendar year during which an annual report on Form 10-K is not required to be
filed pursuant to Section 3.20 on behalf of the Issuing Entity, by April 15 of
each calendar year (or if such day is not a Business Day, the immediately
succeeding Business Day), the Servicer, at its own expense, shall deliver to the
Trustee and the Depositor an officer's assessment of its compliance with the
Servicing Criteria during the preceding calendar year as required by Rules
13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB (the
"Assessment of Compliance"), which assessment shall be substantially in the form
of Exhibit R hereto.

          (b) Not later than (i) March 12 of each calendar year (other than the

calendar year (or if such day is not a Business Day, the immediately succeeding
Business Day), the Servicer, at its own expense, shall cause a nationally or
regionally recognized firm of independent registered public accountants (who may
also render other services to any Servicer, the Sponsor or any Affiliate
thereof) which is a member of the American Institute of Certified Public
Accountants to furnish a statement to the Trustee and the Depositor that attests
to and reports on the

                                      -98-

<PAGE>

Assessment of Compliance provided by such Servicer pursuant to Section 3.18(a)
(the "Accountant's Attestation"). Such Accountant's Attestation shall be in

Securities Act and the Exchange Act.

          (c) The Servicer shall deliver on behalf of any Subservicer and each

is not required by Regulation AB) not later than March 12 of each calendar year

not required to be filed in accordance with the Exchange Act and the rules and
regulations of the Commission, by April 15 of each calendar year (or, in each
case, if such day is not a Business Day, the immediately succeeding Business

          (i) [Reserved].

          (j) [Reserved].

          (k) The Trustee agrees to cause any custodian appointed by it to
indemnify and hold harmless the Trustee, the Depositor and the Servicer and each
Person, if any, who "controls" the Trustee, the Depositor or the Servicer within
the meaning of the Securities Act and its officers, directors and Affiliates
from and against any losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments and other costs and
expenses that such Person may sustain arising out of third party claims based on
(i) the failure of the custodian, if any, to deliver when required any
information required of it pursuant to Section 3.18 or 3.20 or (ii) any material
misstatement or omission contained in any information provided on its behalf
pursuant to Section 3.18 or 3.20.

          (l) Copies of such Assessments of Compliance and Accountant's
Attestations shall be available on the Trustee's website www.etrustee.net to any

Depositor, as applicable, by each party no later than March 12, 2007.

          (m) Each of the parties hereto acknowledges and agrees that the
purpose of this Section 3.18 is to facilitate compliance by the Sponsor and the
Depositor with the provisions of Regulation AB, as such may be amended or
clarified from time to time. Therefore, each of the parties agrees that the
parties' obligations hereunder will be supplemented and modified as necessary to
be consistent with any such amendments, interpretive advice or guidance,
convention or consensus among active participants in the asset-backed securities
markets, advice of counsel, or otherwise in respect of the

                                      -100-

<PAGE>

requirements of Regulation AB and the parties shall comply with requests made by
the Sponsor or the Depositor for delivery of additional or different information
as the Sponsor or the Depositor may determine in good faith is necessary to
comply with the provisions of Regulation AB, provided that such information is
available to such party without unreasonable effort or expense and within such
timeframe as may be reasonably requested. Any such supplementation or
modification shall be made in accordance with Section 10.01 without the consent
of the Certificateholders, and may result in a change in the reports filed by
the Trustee on behalf of the Issuing Entity under the Exchange Act.

     SECTION 3.19. Subordination of Liens.

     In connection with any governmental program under which a Mortgagor may
obtain a benefit in the event the related Mortgaged Property is subject to a
disaster provided that the Mortgagor files a covenant or other lien against the
Mortgaged Property and is required to obtain the subordination thereto of the
Mortgage, the Servicer may cause such subordination to be executed and filed
provided that either (i) the related Mortgage Loan is in default or, in the
Servicer's best judgment, default with respect to such Mortgage Loan is imminent
or (ii) such subordination and participation in such governmental program will
not result in a change in payment expectations with respect to such Mortgage
Loan. For purposes of the preceding sentence, a change in payment expectations
occurs if, as a result of such subordination and participation in such
governmental program, (1) there is a substantial enhancement of the Mortgagor's
capacity to meet the payment obligations under the Mortgage Loan and that
capacity was primarily speculative prior to such subordination and participation
in such governmental program and is adequate after such subordination and
participation in such governmental program or (2) there is a substantial
impairment of the Mortgagor's capacity to meet the payment obligations under the
Mortgage Loan and that capacity was adequate prior to such subordination and
participation in such governmental program and is primarily speculative after
such subordination and participation in such governmental program. The preceding
sentence and clause (ii) of the second preceding sentence are intended to comply
with Treasury Regulations Section 1.1001-3(e)(4) and shall be interpreted in
accordance therewith.

     SECTION 3.20. Periodic Filings

     As set forth on Schedule X hereto, for so long as the Issuing Entity is
subject to the Exchange Act reporting requirements, no later than the end of
business on the 2nd Business Day after the occurrence of an event requiring
disclosure on Form 8K (a "reportable event") (i) the Depositor, the Sponsor or
the Servicer shall have timely notified the Trustee of an item reportable on a
Form 8-K (unless such item is specific to the Trustee, in which case the Trustee
will be deemed to have notice), (ii) shall have delivered to the Trustee, all
information, data, and exhibits required to be provided or filed with such Form
8-K in a word format agreed upon by the Trustee and Depositor, Seller or
Servicer and (iii) the Depositor or the Trustee, to the extent the reportable
item pertains to such party, shall notify the Servicer thereof by telephone. The
Trustee shall not be responsible for determining what information is required to
be filed on a Form 8-K in connection with the transactions contemplated by this
Agreement (unless such information is specific to the Trustee, in which case the
Trustee will be responsible for consulting with the Depositor or Servicer in
making such a determination) or what events shall cause a Form 8-K to be
required to be filed (unless such event is specific to the Trustee, in which
case the Trustee will be responsible for consulting with the Depositor or
Servicer before causing such Form 8-K to be filed) and shall not be liable for
any late filing of a Form 8-K in the event that it does not receive all
information, data and exhibits required to be provided or filed on or prior to
the second Business Day prior to the applicable filing deadline and with respect
to signatures, by noon, New York City time, on the fourth Business Day after the
reportable event. After preparing the Form 8-K on behalf of the Depositor, the

                                      -101-

<PAGE>

Trustee shall, if required, forward electronically a draft copy of the Form 8-K
to the Depositor and the Servicer for review. No later than one and one-half
Business Days after receiving a final copy of the Form 8-K from the Trustee, a
duly authorized representative of the Servicer shall sign the Form 8-K and
return an electronic or fax copy of such signed Form 8-K (with an original
executed hard copy to follow by overnight mail) to the Trustee and the Trustee
shall file such Form 8-K; provided that the Depositor has notified the Trustee
that it approves of the form and substance of such Form 8-K. If a Form 8-K
cannot be filed on time or if a previously filed Form 8-K needs to be amended,
the Trustee will follow the procedures set forth in this Agreement. After filing
with the Commission, the Trustee will, pursuant to this Agreement, make
available on its internet website a final executed copy of each Form 8-K. The
Trustee will have no obligation to prepare, execute or file such Form 8-K or any
liability with respect to any failure to properly prepare, execute or file such
Form 8-K resulting from the Trustee's inability or failure to obtain or receive
any information needed to prepare, arrange for execution or file such Form 8-K
within the time frames required by this paragraph, not resulting from its own
negligence, bad faith or willful misconduct.

     Within fifteen (15) days after each Distribution Date, the Trustee shall,
on behalf of the Issuing Entity and in accordance with industry standards, file
with the Commission via the Electronic Data Gathering and Retrieval System
(EDGAR), a Form 10-D with a copy of the report to the Certificateholders for
such Distribution Date as an exhibit thereto. Any other information provided to
the Trustee by the Servicer or Depositor to be included in Form 10-D shall be
determined and prepared by and at the direction of the Depositor pursuant to the
following paragraph and the Trustee will have no duty or liability for any
failure hereunder to determine or prepare any additional information on Form
10-D ("Additional Form 10-D Disclosure") as set forth in the next paragraph.

     As set forth in Schedule Y hereto, within five (5) calendar days after the
related Distribution Date (i) the parties hereto, as applicable, will be
required to provide to the Depositor and the Servicer, to the extent known to
such party, any Additional Form 10-D Disclosure (including any breaches of pool
asset representations and warranties or transaction covenants of which the party
has written notice and which has not been included on the monthly distribution
report for the period), if applicable, and (ii) the Depositor, to the extent it
deems necessary, forward to the Trustee in EDGAR-compatible form (with a copy to
the Servicer), or in such other form as otherwise agreed upon by the Trustee and
the Depositor, the form and substance of the Additional Form 10-D Disclosure by
the eighth (8th) calendar day after the related Distribution Date. The Depositor
will be responsible for any reasonable fees and expenses incurred by the Trustee
in connection with including any Additional Form 10-D Disclosure on Form 10-D
pursuant to this paragraph.

     After preparing the Form 10-D at the direction of the Depositor, the
Trustee will forward electronically a draft copy of the Form 10-D to the
Depositor and the Servicer for review by the 9th calendar day after the
Distribution Date. No later than two (2) Business Days after receipt of a final
copy after the related Distribution Date, unless the Servicer receives a notice
from the Trustee as described below or a notice from the Depositor that it has
discovered a material deficiency or irregularity with respect to such Form 10-D,
a duly authorized representative of the Servicer shall sign the Form 10-D and
return an electronic or fax copy of such Form 10-D (with an original executed
hard copy to follow by overnight mail) to the Trustee and the Trustee shall file
such Form 10-D within two business days. Unless the Servicer shall have received
notice from the Trustee to the contrary, the Trustee will be deemed to have
represented to the Servicer that the monthly statement has been properly
prepared by the Trustee and the Servicer may rely upon the accuracy thereof in
it execution of the Form 10-D. If a Form 10-D cannot be filed on time (because
of notice from the Trustee per the previous sentence or otherwise)

                                      -102-
<PAGE>

or if a previously filed Form 10-D needs to be amended, the Trustee will follow
the procedures set forth in this Agreement. After filing with the Commission,
the Trustee will make available on its internet website a final executed copy of
each Form 10-D. The Trustee will have no liability with respect to any failure
to properly prepare, execute or file such Form 10-D resulting from the Trustee's
inability or failure to obtain or receive any information needed to prepare,
arrange for execution or file such Form 10-D on a timely basis.

     Prior to March 30, 2007 (and, if applicable, prior to the ninetieth (90th)
calendar day after the end of the fiscal year for the Issuing Entity), the
Trustee shall, on behalf of the Issuing Entity and in accordance with industry
standards, prepare and file with the Commission via EDGAR a Form 10 -K with
respect to the Issuing Entity. Such Form 10-K shall include the following items,
in each case to the extent they have been delivered to the Trustee within the
applicable time frames set forth in this Agreement, (i) an annual compliance
statement for the Servicer and each Subservicer, as described in Section 3.17 of
the Agreement, (ii)(A) the annual reports on Assessment of Compliance with
Servicing Criteria for each Servicer, Subservicer and Subcontractor (unless the
Depositor has determined that such compliance statement is not required by
Regulation AB), as described in Section 3.18 of the Agreement, and (B) if any
Reporting Servicer's report on Assessment of Compliance with Servicing Criteria
described in Section 3.18 identifies any material instance of noncompliance,
disclosure identifying such instance of noncompliance, or if any report on
assessment of compliance with servicing criteria described in Section 3.18 of
the Agreement is not included as an exhibit to such Form 10-K, disclosure that
such report is not included and an explanation why such report is not included,
(iii)(A) the registered public accounting firm attestation report for the
Servicer and each Subservicer, as described in Section 3.18 of the Agreement,
and (B) if any registered public accounting firm attestation report described in
the Section 3.18 of the Agreement identifies any material instance of
noncompliance, disclosure identifying such instance of noncompliance, or if any
such registered public accounting firm attestation report is not included as an
exhibit to such Form 10-K, disclosure that such report is not included and an
explanation why such report is not included, and (iv) a Sarbanes-Oxley
Certification in the form attached hereto as Exhibit T, executed by the senior
officer in charge of securitizations of the Servicer. Any disclosure or
information in addition to (i) through (iv) above that is required to be
included on Form 10-K ("Additional Form 10-K Disclosure") shall be determined
and prepared by and at the direction of the Depositor pursuant to the following
paragraph and the Trustee will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-K Disclosure, except as
set forth in the next paragraph.

     As set forth in Schedule Z hereto, no later than March 12 of each year that
the Issuing Entity is subject to the Exchange Act reporting requirements,
commencing in 2007, (i) certain parties to the transaction shall be required to
provide to the Depositor and the Servicer, to the extent known, any Additional
Form 10-K Disclosure, if applicable, and (ii) the Depositor shall, to the extent
it deems necessary, forward to the Trustee in EDGAR-compatible form, or in such
other form as otherwise agreed upon by the Trustee and the Depositor, the form
and substance of the Additional Form 10-K Disclosure by March 15. The Depositor
will be responsible for any reasonable fees and expenses incurred by the Trustee
in connection with including any Additional Form 10-K Disclosure on Form 10-K
pursuant to this paragraph.

     After preparing the Form 10-K, the Trustee shall forward electronically a
draft copy of the Form 10-K to the Depositor and the Servicer for review. Upon
the request of the Servicer, the Depositor shall confirm that it has reviewed
the Form 10-K, that it has been properly prepared and that the Servicer may rely
on the accuracy thereof (other than with respect to any portion of the Form 10-K
or any exhibit thereto provided by the Servicer (other than any portion thereof
with respect to which the Servicer has

                                     -103-

<PAGE>

relied on the Trustee)). No later than 5:00 p.m. EST on the 3rd Business Day
following receipt of a final copy of the Form 10-K and if requested, the
above-described confirmation from the Depositor, a senior officer of the
Servicer shall sign the Form 10-K and return an electronic or fax copy of such
signed Form 10-K (with an original executed hard copy to follow by overnight
mail) to the Trustee and the Trustee shall file such Form 10-K by March 30th. If
a Form 10-K cannot be filed on time or if a previously filed Form 10-K needs to
be amended, the Trustee will follow the procedures set forth in the Agreement.
After filing with the Commission, the Trustee will, pursuant to the Agreement,
make available on its internet website a final executed copy of each Form 10-K.
The Trustee shall have no liability with respect to any failure to properly
prepare, execute or file such Form 10-K resulting from the Trustee's inability
or failure to obtain or receive any information needed to prepare, arrange for
execution or file such Form 10-K on a timely basis.

     Each Form 10-K shall include a certification (the "Sarbanes-Oxley
Certification") which shall be in the form attached hereto as Exhibit T. The
Servicer will cause its senior officer in charge of securitization to execute
the Sarbanes-Oxley Certification required pursuant to Rule 13a -14 under the
Securities Exchange Act of 1934, as amended, and to deliver the original
executed Sarbanes-Oxley Certification to the Trustee by March 12 of each year in
which the Issuing Entity is subject to the reporting requirements of the
Exchange Act. In connection therewith, each of the Trustee and the Servicer
shall sign a certification (in the form attached hereto as Exhibit K and Exhibit
L, respectively) for the benefit of the Servicer and its officers, directors and
Affiliates regarding certain aspects of the Sarbanes-Oxley Certification. To the
extent any information or exhibits required to be included in the Form 10-K are
not timely received by the Trustee prior to March 30, the Trustee shall, on
behalf of the Trust, file a Form 12B-25 and one or more amended Form 10-Ks, to
the extent such amendments are accepted pursuant to the Exchange Act, to include
such missing information or exhibits promptly after receipt thereof by the
Trustee.

     Promptly following the first date legally permissible under applicable
regulations and interpretations of the Commission, the Trustee shall, on behalf
of the Issuing Entity and in accordance with industry standards, file with the
Commission via EDGAR a Form 15 Suspension Notification with respect to the
Issuing Entity, if applicable.

     The Servicer agrees to furnish to the Trustee promptly, from time to time
upon request, such further information, reports, and financial statements within
its control related to this Agreement and the Mortgage Loans as is reasonably
necessary to prepare and file all necessary reports with the Commission. The
Trustee shall have no responsibility to file any items with the Commission other
than those specified in this section and the Servicer shall execute any and all
Form 8-Ks, Form 10-Ds and Form 10-Ks required hereunder.

     If the Commission issues additional interpretative guidance or promulgates
additional rules or regulations with respect to Regulation AB or otherwise, or
if other changes in applicable law occur, that would require the reporting
arrangements, or the allocation of responsibilities with respect thereto,
described in this Section 3.20, to be conducted differently than as described,
the Depositor, the Servicer, and the Trustee will reasonably cooperate to amend
the provisions of this Section 3.20 in order to comply with such amended
reporting requirements and such amendment of this Section 3.20. Any such
amendment shall be made in accordance with Section 10.01 without the consent of
the Certificateholders, and may result in a change in the reports filed by the
Trustee on behalf of the Issuing Entity under the Exchange Act. Notwithstanding
the foregoing, the Depositor, the Servicer, and the Trustee shall not be

                                     -104-

<PAGE>

obligated to enter into any amendment pursuant to this Section 3.20 that
adversely affects its obligations and immunities under this Agreement.

     The Depositor, the Servicer and the Trustee agree to use their good faith
efforts to cooperate in complying with the requirements of this Section 3.20.

     SECTION 3.21. Indemnification by Trustee

     The Trustee shall indemnify and hold harmless the Depositor, the Servicer
and their respective officers, directors, agents and Affiliates from and against
any losses, damages, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments and other costs and expenses arising out of or based
upon a breach by the Trustee or any of its officers, directors, agents or
Affiliates of its obligations under Sections 3.18 and 3.20, any material
misstatement or omission in any documents prepared thereunder (to the extent the
Trustee is responsible for providing information or calculating amounts included
in such information), the failure of the Trustee to deliver when required any
Assessment of Compliance or Accountant's Attestation required of it pursuant to
Section 3.18, or any material misstatement or omission contained in any
Assessment of Compliance or Accountant's Attestation provided on its behalf
pursuant to Section 3.18, or the negligence, bad faith or willful misconduct of
the Trustee in connection therewith. If the indemnification provided for herein
is unavailable or insufficient to hold harmless the indemnified parties, then
the Trustee agrees that it shall contribute to the amount paid or payable by the
indemnified parties as a result of the losses, claims, damages or liabilities of
the indemnified parties in such proportion as is appropriate to reflect the
relative fault of the Trustee on the one hand and of the indemnified parties on
the other.

     SECTION 3.22. Indemnification by Servicer

     The Servicer shall indemnify and hold harmless the Trustee and the
Depositor and their respective officers, directors, agents and Affiliates from
and against any losses, damages, penalties, fines, forfeitures, reasonable legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach by the Servicer or any of its officers, directors, agents or
Affiliates of its obligations under Sections 3.17, 3.18 and 3.20, any material
misstatement or omission in any documents prepared thereunder (to the extent the
Servicer is responsible for providing information or calculating amounts
included in such information), the failure of such Servicer or any related
Sub-Servicer or Subcontractor to deliver or cause to be delivered when required
any Assessment of Compliance or Accountant's Attestation required of it pursuant
to Section 3.18 or Annual Statement of Compliance required pursuant to Section
3.17, as applicable, or any material misstatement or omission contained in any
Assessment of Compliance, Accountant's Attestation or Annual Statement as to
Compliance provided on its behalf pursuant to Section 3.18 or 3.17, as
applicable, or the negligence, bad faith or willful misconduct of the Servicer
in connection therewith. If the indemnification provided for herein is
unavailable or insufficient to hold harmless the indemnified parties, then the
Servicer agrees that it shall contribute to the amount paid or payable by the
indemnified parties as a result of the losses, claims, damages or liabilities of
the indemnified parties in such proportion as is appropriate to reflect the
relative fault of the Servicer on the one hand and the indemnified parties on
the other.

     Notwithstanding the foregoing, the Servicer shall be entitled to rely
conclusively on the accuracy of the information or data provided to the Servicer
in the respective Assessment of Compliance regarding the Servicing Criteria
applicable to the Trustee under Sections 3.18(e) and 3.18(f) or the Depositor
under Sections 3.18(g) and 3.18(h) in connection with the Servicer's document
preparation under Sections 3.17,

                                     -105-

shall have no liability for any errors in such information.

     SECTION 3.23. Prepayment Charge Reporting Requirements

     Promptly after each Distribution Date, the Servicer shall provide to the
Depositor and the Trustee the following information with regard to each Mortgage
Loan that has prepaid during the related Prepayment Period:

          (iv) original principal balance;

          (v) Prepayment Charge amount due; and

          (vi) Prepayment Charge amount collected.

     SECTION 3.24. Information to the Trustee

     Two Business Days after the 15th day of each month, but not later than the
18th day of each month, the Servicer shall furnish to the Trustee in electronic
format (1) the Remittance Report pursuant to Section 4.03 and (ii) a delinquency
report in such form or forms as the Trustee and the Servicer may from time to
time agree for the period ending on the last Business Day of the preceding month
(and with respect to prepayments in full, for the period ending on the 14th day
of the month in which such report is to be furnished); provided, however, that
in the event the 18th day is not a Business Day, the aforementioned reports
shall be furnished by the Servicer to the Trustee on the next Business Day; and
provided, further, that in the event there are three non-Business Days preceding
the 18th day, the Servicer will (a) furnish to the Trustee, on or before the
18th day of the month, the aforementioned reports, which will not include

     SECTION 3.25. Indemnification

     The Servicer shall indemnify the Sponsor, the Issuing Entity, the Trustee
(in its individual capacity and in its capacity as trustee), the Depositor and
their officers, directors, employees and agents and hold each of them harmless
against any and all claims, losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments, and any other
costs, fees and expenses that any of such parties may sustain in any way related
to the failure of the Servicer to perform its duties and service the Mortgage
Loans in compliance with the terms of this Agreement by reason of negligence,
willful misfeasance or bad faith in the performance of its duties or by reason
of reckless disregard of obligations and duties hereunder. The Servicer
immediately shall notify the Sponsor, the Trustee and the Depositor or any other
relevant party if a claim is made by a third party with respect to such party
and this Agreement or the Mortgage Loans and, if subject to this indemnification
obligation, assume (with the

                                     -106-

<PAGE>

prior written consent of the indemnified party, which consent shall not be
unreasonably withheld or delayed) the defense of any such claim and pay all
expenses in connection therewith, including counsel fees, and promptly pay,
discharge and satisfy any judgment or decree which may be entered against it or
any of such parties in respect of such claim. The Servicer shall follow any
reasonable written instructions received from the Trustee in connection with
such claim, it being understood that the Trustee shall have no duty to monitor
or give instructions with respect to such claims, and the Servicer will not have
any liability for following such instructions. The Servicer shall provide the
Depositor and the Trustee with a written report of all expenses and advances
incurred by the Servicer pursuant to this Section 3.25(a), and the Servicer
shall promptly reimburse itself from the assets of the Trust Fund in the
Collection Account for all amounts advanced by it pursuant to the preceding
sentence except when the claim in any way relates to the gross negligence, bad
faith or willful misconduct of the Servicer. The provisions of this paragraph
shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

     SECTION 3.26. Nonsolicitation

     For as long as the Servicer services the Mortgage Loans, the Servicer
covenants that it will not, and that it will ensure that its Affiliates and
agents will not, directly solicit or provide information for any other party to
solicit for prepayment or refinancing of any of the Mortgage Loans by the
related Mortgagors. For the purposes of the foregoing, neither the Servicer nor
any Affiliate of the Servicer shall be deemed to directly solicit any Mortgagor
if the Servicer received a request for verification of mortgage, a request for
demand for payoff, a mortgagor initiated written or verbal communication
indicating a desire to prepay or refinance the related Mortgage Loan or the
Mortgagor initiates a title search, or if the Servicer responds to a request
from a Mortgagor regarding a refinancing or if the Mortgagor receives marketing
materials which are generally disseminated or if the Mortgage Loan is delinquent
and the Servicer refers a Mortgagor to a person for possible refinancing or
provides Mortgagor's contact information to such person. It is understood that
the promotions undertaken by the Servicer that are directed to the general
public at large, or certain segments thereof, shall not constitute solicitation
as that term is used in this Section 3.26.

     SECTION 3.27. High Cost Mortgage Loans

     In the event that the Servicer reasonably determines that a Mortgage Loan
may be a "high cost mortgage loan", "high cost home", "covered", "high cost",
"high risk home", "predatory" or similarly classified loan under any applicable
state, federal or local law, the Servicer may notify the Depositor, the Sponsor
and the Trustee thereof; the Servicer may terminate its servicing thereof; and
such determination shall be deemed to materially and adversely affect the
interests of the Certificateholders in such Mortgage Loan and the Transferor, or
the Sponsor, in event the Transferor does not do so, will repurchase the
Mortgage Loan within a 30 day period from the date of the notice in the manner
described in Section 2.05.

                                   ARTICLE IV

                                  DISTRIBUTIONS

     SECTION 4.01. Advances

                                     -107-

<PAGE>

          (a) Subject to the conditions of this Article IV, the Servicer, as
required below, shall make an Advance and deposit such Advance in the Collection
Account. The Servicer shall use commercially reasonable efforts to remit each
such Advance no later than 2:30 p.m. Eastern time, but in any case no later than
4:00 p.m. Eastern time, on the Servicer Remittance Date in immediately available
funds. The Servicer shall be obligated to make any such Advance only to the
extent that such advance would not be a Non-Recoverable Advance. If the Servicer
shall have determined that it has made a Non-Recoverable Advance or that a
proposed Advance or a lesser portion of such Advance would constitute a
Non-Recoverable Advance, the Servicer shall deliver (i) to the Trustee for the
benefit of the Certificateholders, funds constituting the remaining portion of
such Advance, if applicable, and (ii) to the Depositor, each Rating Agency and
the Trustee an Officer's Certificate setting forth the basis for such
determination. The Servicer may, in its sole discretion, make an Advance with
respect to the principal portion of the final Scheduled Payment on a Balloon
Loan, but the Servicer is under no obligation to do so; provided, however, that
nothing in this sentence shall affect the Servicer's obligation under this
Section 4.01 to Advance the interest portion of the final Scheduled Payment with
respect to a Balloon Loan as if such Balloon Loan were a fully amortizing
Mortgage Loan. If a Mortgagor does not pay its final Scheduled Payment on a
Balloon Loan when due, the Servicer shall Advance (unless it determines in its
good faith judgment that such amounts would constitute a Non-Recoverable
Advance) a full month of interest (net of the Servicing Fee) on the Stated
Principal Balance thereof each month until its Stated Principal Balance is
reduced to zero.

     In lieu of making all or a portion of such Advance from its own funds, the
Servicer may (i) cause to be made an appropriate entry in its records relating
to the Collection Account that any amount held for future distribution has been
used by the Servicer in discharge of its obligation to make any such Advance and
(ii) transfer such funds from the Collection Account to the Certificate Account.
In addition, the Servicer shall have the right to reimburse itself for any such
Advance from amounts held from time to time in the Collection Account to the
extent such amounts are not then required to be distributed. Any funds so
applied and transferred pursuant to the previous two sentences shall be replaced
by the Servicer by deposit in the Collection Account no later than the close of
business on the Servicer Remittance Date on which such funds are required to be
distributed pursuant to this Agreement. The Servicer shall be entitled to be
reimbursed from the Collection Account for all Advances of its own funds made
pursuant to this Section as provided in Section 3.08. The obligation to make
Advances with respect to any Mortgage Loan shall continue until the earlier of
(i) such Mortgage Loan is paid in full, (ii) the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Issuing Entity pursuant to any
applicable provision of this Agreement, except as otherwise provided in this
Section 4.01, (iii) the Servicer determines in its good faith judgment that such
amounts would constitute a Non-Recoverable Advance as provided in the preceding
paragraph or (iv) the date on which such Mortgage Loan becomes 150 days
delinquent as set forth below.

          (b) Notwithstanding anything in this Agreement to the contrary
(including, but not limited to, Sections 3.01 and 4.01(a) hereof), no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer
(including for the avoidance of doubt, the Trustee as successor servicer) if
such Advance or Servicing Advance would, if made, constitute a Non-Recoverable
Advance or a Non-Recoverable Servicing Advance. The determination by the
Servicer that it has made a Non-Recoverable Advance or a Non-Recoverable
Servicing Advance or that any proposed Advance or Servicing Advance, if made,
would constitute a Non-Recoverable Advance or a Non-Recoverable Servicing
Advance, respectively, shall be evidenced by an Officer's Certificate of the
Servicer delivered to the Depositor and the Trustee. In addition, the Servicer
shall not be required to advance any Relief Act Shortfalls.

                                     -108-

<PAGE>

          (c) Notwithstanding the foregoing, the Servicer shall not be required
to make any Advances for any Mortgage Loan after such Mortgage Loan becomes 150
days delinquent. The Servicer shall identify such delinquent Mortgage Loans in
the Servicer Statement referenced in Section 3.24. In addition, the Servicer
shall provide the Trustee with an Officer's Certificate listing such delinquent
Mortgage Loans and certifying that such loans are 150 days or more delinquent.

     SECTION 4.02. Reduction of Servicing Compensation in Connection with
Prepayment Interest Shortfalls

     In the event that any Mortgage Loan is the subject of a Prepayment Interest
Shortfall, the Servicer shall, from amounts in respect of the Servicing Fee for
such Distribution Date, deposit into the Collection Account, as a reduction of
the Servicing Fee for such Distribution Date, no later than the Servicer
Remittance Date immediately preceding such Distribution Date, an amount up to
the Prepayment Interest Shortfall. In case of such deposit, the Servicer shall
not be entitled to any recovery or reimbursement from the Depositor, the
Trustee, the Issuing Entity or the Certificateholders. With respect to any
Distribution Date, to the extent that the Prepayment Interest Shortfall exceeds
Compensating Interest (such excess, a "Non-Supported Interest Shortfall"), such
Non-Supported Interest Shortfall shall reduce the Current Interest with respect
to each Class of Certificates, pro rata based upon the amount of interest each
such Class would otherwise be entitled to receive on such Distribution Date.
Notwithstanding the foregoing, there shall be no reduction of the Servicing Fee
in connection with Prepayment Interest Shortfalls related to the Relief Act and
the Servicer shall not be obligated to pay Compensating Interest with respect to
Prepayment Interest Shortfalls related to the Relief Act.

     SECTION 4.03. Distributions on the REMIC Interests

     On each Distribution Date, amounts on deposit in the Certificate Account
shall be treated for federal income tax purposes as applied to distributions on
the interests in each of the SWAP REMIC and the Lower Tier REMIC in an amount
sufficient to make the distributions on the respective Certificates on such
Distribution Date in accordance with the provisions of Section 4.04.

     SECTION 4.04. Distributions

          (a) [Reserved].

          (b) On each Distribution Date (or on the related Swap Payment Date,
with respect to payments to the Supplemental Interest Trust), the Trustee shall,
to the extent of funds then available, make the following distributions from
funds then available in the Certificate Account, of an amount equal to the
Interest Funds, in the following order of priority:

          (i) to the Class P Certificates, an amount equal to any Prepayment
     Charges received with respect to the Mortgage Loans and all amounts paid by
     the Servicer, the Sponsor or the Transferor in respect of Prepayment
     Charges pursuant to this Agreement or the Transfer Agreement, as
     applicable, and all amounts received in respect of any indemnification paid
     as a result of a Prepayment Charge being unenforceable in breach of the
     representations and warranties set forth in the Sale Agreement or the
     Transfer Agreement for the related Prepayment Period;

                                     -109-

<PAGE>

          (ii) to the Supplemental Interest Trust, any Net Swap Payments owed to
     the Swap Counterparty;

          (iii) to the Supplemental Interest Trust, any Swap Termination Payment
     owed by the Supplemental Interest Trust to the Swap Counterparty (other
     than any Defaulted Swap Termination Payment);

          (iv) concurrently, to each class of the Class A Certificates, the
     Current Interest and any Interest Carry Forward Amount with respect to each
     such class; provided, however, that if Interest Funds are insufficient to
     make a full distribution of the aggregate Current Interest and the
     aggregate Interest Carry Forward Amount to the Class A Certificates,
     Interest Funds will be distributed pro rata among each Class of the Class A
     Certificates based upon the ratio of (x) the Current Interest and Interest
     Carry Forward Amount for each class of the Class A Certificates to (y) the
     total amount of Current Interest and any Interest Carry Forward Amount for
     the Class A-1, Class A-2 and Class R Certificates in the aggregate;

          (v) to the Class M-1 Certificates, the Current Interest for such class
     and any Interest Carry Forward Amount with respect to such Class;

          (vi) to the Class M-2 Certificates, the Current Interest for such
     class and any Interest Carry Forward Amount with respect to such Class;

          (vii) to the Class M-3 Certificates, the Current Interest for such
     class and any Interest Carry Forward Amount with respect to such Class;

          (viii) to the Class M-4 Certificates, the Current Interest for such
     class and any Interest Carry Forward Amount with respect to such Class;

          (ix) to the Class M-5 Certificates, the Current Interest for such
     class and any Interest Carry Forward Amount with respect to such Class;

          (x) to the Class M-6 Certificates, the Current Interest for such class
     and any Interest Carry Forward Amount with respect to such Class;

          (xi) to the Class B-1 Certificates, the Current Interest for each such
     class and any Interest Carry Forward Amount with respect to each such
     Class;

          (xii) to the Class B-2 Certificates, the Current Interest for each
     such class and any Interest Carry Forward Amount with respect to each such
     Class;

          (xiii) to the Class B-3 Certificates, the Current Interest for each
     such class and any Interest Carry Forward Amount with respect to each such
     Class;

          (xiv) to the Class B-4 Certificates, the Current Interest for each
     such class and any Interest Carry Forward Amount with respect to each such
     Class; and

          (xv) any remainder pursuant to Section 4.04(f) hereof.

                                     -110-

     On each Distribution Date, subject to the proviso in (iv) above, Interest
Funds received on the Group One Mortgage Loans will be deemed to be distributed
to the Class R and Class A-1 Certificates and Interest Funds received on the
Group Two Mortgage Loans will be deemed to be distributed to the Class A-2
Certificates, in each case, until the related Current Interest and Interest
Carry Forward Amount of each such Class of Certificates for such Distribution
Date has been paid in full. Thereafter, Interest Funds not required for such
distributions are available to be applied to if necessary, to the Class or
Classes of Certificates that are not related to such group of Mortgage Loans.

          (c) [RESERVED]

          (d) On each Distribution Date (or on the related Swap Payment Date,
with respect to payments to the Supplemental Interest Trust), the Trustee shall,
to the extent of funds then available, make the following distributions from the
Certificate Account of an amount equal to the Principal Distribution Amount in
the following order of priority, and each such distribution shall be made only
after all distributions pursuant to Section 4.04(b) above shall have been made
until such amount shall have been fully distributed for such Distribution Date:

          (i) to the Supplemental Interest Trust, any Swap Termination Payment
     owed by the Supplemental Interest Trust to the Swap Counterparty (other
     than any Defaulted Swap Termination Payment), to the extent not paid
     pursuant to Section 4.04(b)(iii);

          (ii) to the Supplemental Interest Trust, any Net Swap Payments owed to

     Amount shall be distributed as follows:

               (A) the Group One Principal Distribution Amount will be
          distributed sequentially to the Class R and Class A-1 Certificates, in
          that order, until the Certificate Principal Balance of each such class
          has been reduced to zero;

               (B) the Group Two Principal Distribution Amount will be
          distributed as follows: sequentially, to the Class A-2A Certificates

          distributions allocated to the Class A-2A, Class A-2B, Class A-2C and
          Class A-2D Certificates are required to be allocated pro rata, among
          such Classes, based on their respective Certificate Principal

          to zero;

     Principal Balance is reduced to zero.

          (j) Subject to Section 9.02 hereof respecting the final distribution,
on each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire transfer
in immediately available funds to the account of such holder at a bank or other
entity having appropriate facilities therefor, if such Holder has so notified
the Trustee at least five (5) Business Days prior to the related Record Date or,
if not, by check mailed by first class mail to such Certificateholder at the
address of such holder appearing in the Certificate Register. Notwithstanding
the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the name
of a Depository shall be made to such Depository in immediately available funds.

     In accordance with this Agreement, the Servicer shall prepare and deliver
an electronic report (the "Remittance Report") to the Trustee (or by such other
means as the Servicer and the Trustee may agree from time to time) containing
such data and information as to permit the Trustee to prepare the Monthly
Statement to Certificateholders and make the required distributions for the
related Distribution Date. The Trustee will prepare the Monthly Report based
solely upon the information received from the Servicer.

          (k) The Trustee is hereby directed by the Depositor to execute the Cap
Contracts on behalf of the Supplemental Interest Trust in the form presented to
it by the Depositor and shall have no responsibility for the contents of such
Cap Contracts, including, without limitation, the representations and warranties
contained therein. Any funds payable by the Trustee under the Cap Contracts at
closing shall be paid by the Depositor. Notwithstanding anything to the contrary
contained herein or in any Cap Contract, except as set forth in Section 2 of
each Cap Contract, the Trust shall not be required to make any payments to the
counterparty under any Cap Contract. Any payments received under the terms of
the related Cap Contract will be available to pay the holders of the related
Class A-1, Class A-2, Class M and Class B Certificates up to the amount of any
Floating Rate Certificate Carryovers remaining after all other distributions
required under this Section 4.04 are made on such Distribution Date, other than
Floating Rate Certificate Carryovers attributable to the fact that Applied
Realized Loss Amounts are not allocated to the Class A Certificates. Any amounts
received under the terms of any Cap Contract on a Distribution Date that are not
used to pay such Floating Rate Certificate Carryovers will be distributed to the
holders of the Class C Certificates. Payments in respect of such Floating Rate
Certificate Carryovers from proceeds of a Cap Contract shall be paid to the
related Classes of Class A-1, Class A-2, Class M and Class B Certificates, pro
rata based upon such Floating Rate Certificate Carryovers for each such class of
Class A-1, Class A-2, Class M and Class B Certificates. Amounts received on the
Class A-1 Cap Contract will only be available to make payments on the Class A-1
Certificates, amounts received on the Class A-2 Cap Contract will only be
available to make payments on the Class A-2 Certificates, amounts received on
the Subordinate Certificates Cap Contract will only be available to make
payments on the Subordinate Certificates.

          (i) On or prior to the related Cap Contract Termination Date, amounts,
     if any, received by the Trustee for the benefit of the Supplemental
     Interest Trust in respect of the related Cap Contract shall be deposited by
     the Trustee into the Supplemental Interest Trust and will be used to pay
     Floating Rate Certificate Carryovers on the related Class A-1, Class A-2,
     Class M and Class B Certificates to the extent provided in the immediately
     preceding paragraph. With respect to any Distribution Date on or prior to

     the Cap Contract Counterparty under the related Cap Contract will equal the

                                     -115-

<PAGE>

     product of (i) the excess of (x) One-Month LIBOR (as determined by the Cap
     Contract Counterparty and subject to a cap equal to the rate with respect
     to such Distribution Date as shown under the heading "1ML Upper Collar" in
     the schedule to the related Cap Contract), over (y) the rate with respect
     to such Distribution Date as shown under the heading "1ML Strike Lower
     Collar" in the schedule to the related Cap Contract, (ii) an amount equal
     to the lesser of (x) the related Cap Contract Notional Balance for such
     Distribution Date and (y) the outstanding Certificate Principal Balance of
     the related classes of Certificates and (iii) the number of days in such
     Accrual Period, divided by 360. If a payment is made to the Supplemental
     Interest Trust under a Cap Contract and the Trustee is required to
     distribute excess amounts to the holders of the Class C Certificates as
     described above, information regarding such distribution will be included
     in the monthly statement made available on the Trustee's website pursuant
     to Section 4.05 hereof.

          (ii) Amounts on deposit in the Supplemental Interest Trust will remain
     uninvested pending distribution to Certificateholders.

          (iii) Each Cap Contract is scheduled to remain in effect until the
     related Cap Contract Termination Date and will be subject to early
     termination only in limited circumstances. Such circumstances include
     certain insolvency or bankruptcy events in relation to the Cap Contract
     Counterparty (after a grace period of three Local Business Days, as defined
     in the related Cap Contract, after notice of such failure is received by
     the Cap Contract Counterparty) to make a payment due under the related Cap
     Contract, the failure by the Cap Contract Counterparty (after a cure period
     of twenty (20) days after notice of such failure is received) to perform
     any other agreement made by it under the related Cap Contract, the
     termination of the Trust Fund and the related Cap Contract becoming illegal
     or subject to certain kinds of taxation.

          (l) On the Closing Date, the Supplemental Interest Trust shall be
established and maintained pursuant to this Agreement, as a separate trust, the
corpus of which shall be held by the Trustee for the benefit of the holders of
the Certificates as a segregated subtrust of the Trust Fund. The Supplemental
Interest Trust shall be an Eligible Account, and funds deposited therein shall
be held separate and apart from, and shall not be commingled with, any other
moneys, including, without limitation, other moneys of the Trustee held pursuant
to this Agreement. In no event shall any funds deposited in the Supplemental
Interest Trust be credited to or made available to any other account of the
Trust Fund. The records of the Trustee shall at all times reflect that the
Supplemental Interest Trust is a subtrust of the Trust Fund, the assets of which
are segregated from other assets of the Trust Fund.

     The Trustee shall enforce all of the rights of the Supplemental Interest
Trust and exercise any remedies under the Swap Agreement and, in the event the
Swap Agreement is terminated as a result of the designation by either party
thereto of an Early Termination Date (as defined in the Swap Agreement), find a
replacement counterparty to enter into a replacement swap agreement utilizing
the amounts of the net Swap Termination Payments received.

     For each Distribution Date, through and including the Distribution Date in
September 2009, the Trustee shall, based on the Significance Estimate (which
shall be provided to the Trustee by the Depositor within five (5) Business Days
prior to the Distribution Date), calculate the Significance Percentage of the
Swap Agreement. If on any such Distribution Date, the Significance Percentage is
equal to or greater than 9%, the Trustee shall promptly notify the Depositor and
the Depositor, on behalf of the Trustee, shall obtain the financial information
required to be delivered by the Swap Counterparty pursuant to the terms of the
Swap Agreement. If, on any succeeding Distribution Date through and including
the Distribution

                                     -116-

<PAGE>

Date in September 2009, the Significance Percentage is equal to or greater than
10%, the Trustee shall promptly notify the Depositor and the Depositor shall,
within five (5) Business Days of such Distribution Date, deliver to the Trustee
the financial information provided to it by the Swap Counterparty for inclusion
in the Form 10-D relating to such Distribution Date.

     Any Swap Termination Payment received by the Trustee shall be deposited in
the Supplemental Interest Trust and shall be used to make any upfront payment
required under a replacement swap agreement and any upfront payment received
from the counterparty to a replacement swap agreement shall be used to pay any
Swap Termination Payment owed to the Swap Counterparty.

     Notwithstanding anything contained herein, in the event that a replacement
swap agreement cannot be obtained within thirty (30) days after receipt by the
Trustee of the Swap Termination Payment paid by the terminated Swap
Counterparty, the Trustee shall deposit such Swap Termination Payment into a
separate, segregated non-interest bearing subtrust established by the Trustee
and the Trustee shall, on each Distribution Date following receipt of such Swap
Termination Payment, withdraw from such subtrust, an amount equal to the Net
Swap Payment, if any, that would have been paid to the Supplemental Interest
Trust by the original Swap Counterparty (computed in accordance with the
original Swap Agreement) and distribute such amount in accordance with Section
4.04(1)(i)-(viii) of this Agreement. Any such subtrust shall not be an asset of
any REMIC. Any amounts remaining in such subtrust shall be distributed to the
holders of the Class C Certificates on the Distribution Date following the
earlier of (i) the termination of the Trust Fund pursuant to Section 9.01 and
(ii) September 25, 2009.

     On any Distribution Date, any Swap Termination Payments or Net Swap
Payments owed to the Swap Counterparty will be paid out of, or any Net Swap
Payments or Swap Termination Payments received from the Swap Counterparty will
be deposited into, the Supplemental Interest Trust. The Supplemental Interest
Trust will not be an asset of any REMIC. Funds in the Supplemental Interest
Trust (other than proceeds of the Cap Contract) shall be distributed in the
following order of priority by the Trustee:

          (i) to the Swap Counterparty, all Net Swap Payments, if any, owed to
     the Swap Counterparty for such Distribution Date;

          (ii) to the Swap Counterparty, any Swap Termination Payment, other
     than a Defaulted Swap Termination Payment, if any, owed to the Swap
     Counterparty;

          (iii) to each class of the Class A Certificates, on a pro rata basis,
     any Current Interest and any Interest Carry Forward Amount with respect to
     such class to the extent unpaid;

     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the
     Class M-5 Certificates, the Class M-6 Certificates, the Class B-1

     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the

     the Class B-4 Certificates, in that order, any Interest Carry Forward with
     respect to such class to the extent unpaid;

                                     -117-
<PAGE>

          (vi) to the Class A, Class R, Class M and Class B Certificates, to pay
     principal as described and in the same manner and order of priority as set
     forth in Sections 4.04(d)(iii) through 4.04(d)(xiii) in order to restore
     levels of the Overcollateralization Amount, and after giving effect to
     distributions from Principal Distribution Amount for each such Class;

          (vii) sequentially, to the Class M-1 Certificates, the Class M-2
     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the
     Class M-5 Certificates, the Class M-6 Certificates, the Class B-1
     Certificates, the Class B-2 Certificates, the Class B-3 Certificates and
     the Class B-4 Certificates, in that order, any Unpaid Realized Loss Amount
     for such class to the extent unpaid;

          (viii) to the Class A, Class R, Class M and Class B Certificates, on a
     pro rata basis, any Floating Rate Certificate Carryover to the extent not
     paid based on the amount of such unpaid Floating Rate Certificate
     Carryover;

          (ix) to the Swap Counterparty, any Defaulted Swap Termination Payment
     owed to the Swap Counterparty to the extent not already paid; and

          (x) to the Class C Certificates any remaining amount.

     Notwithstanding the foregoing, however, after giving effect to proposed
distributions on any Distribution Date, the sum of the cumulative amounts
distributed pursuant to clause (vi) above and the cumulative amounts distributed
pursuant to clause (vii) above shall be limited to the aggregate amount of
cumulative Realized Losses incurred from the Cut-off Date through the last day
of the related Prepayment Period.

     Upon termination of the Trust Fund, any amounts remaining in the
Supplemental Interest Trust shall be distributed pursuant to the priorities set
forth in this Section 4.04(l).

     With respect to the failure of the Swap Counterparty to perform any of its
obligations under the Swap Agreement, the breach by the Swap Counterparty of any
of its representations and warranties made pursuant to the Swap Agreement, or
the termination of the Swap Agreement, the Trustee shall send any notices and
make any demands required hereunder.

(1)  The Class C Certificates shall not have minimum dollar denominations as the
     Certificate Principal Balance thereof shall vary over time as described
     herein and shall be issued in a minimum percentage interest of 25% and an
     aggregate percentage interest of 100%.

(2)  The Class P Certificates shall not have minimum dollar denominations or
     Certificate Principal Balances and shall be issued in a minimum percentage
     interest of 100%.

     The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer. Certificates bearing the manual
or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall bind
the Issuing Entity, notwithstanding that such individuals or any of them have
ceased to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such authentication and
delivery. No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate a
certificate of authentication substantially in the form set forth as attached
hereto executed by the Authenticating Agent by manual signature, and

                                      -123-

<PAGE>

such certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. On the Closing Date, the Authenticating Agent shall
authenticate the Certificates to be issued at the written direction of the
Depositor, or any Affiliate thereof.

     The Certificates sold in offshore transactions in reliance on Regulation S
shall be issued initially in the form of one or more permanent global
certificates in definitive, fully registered form without interest coupons with
the applicable legends set forth in Exhibit A hereto added to the form of each
such Certificate (each, a "Regulation S Book-Entry Certificate"), which shall be
deposited on behalf of the Holders of such Certificates represented thereby with
the Trustee, as custodian for DTC and registered in the name of a nominee of
DTC, duly executed and authenticated by the Trustee and the Authenticating Agent
as hereinafter provided. The aggregate principal amounts of the Regulation S
Book-Entry Certificates may from time to time be increased or decreased by
adjustments made on the records of the Trustee or DTC or its nominee, as the
case may be, as hereinafter provided.

     The Certificates sold in reliance on Rule 144A shall be issued initially in
the form of one or more permanent global certificates in definitive, fully
registered form without interest coupons with the applicable legends set forth
in Exhibit A hereto added to the form of each such Certificate (each, a "Rule
144A Book-Entry Certificate"), which shall be deposited on behalf of the Holders
of such Certificates represented thereby with the Trustee, as custodian for DTC
and registered in the name of a nominee of DTC, duly executed and authenticated
by the Trustee and the Authenticating Agent as hereinafter provided. The
aggregate principal amounts of the Rule 144A Book-Entry Certificates may from
time to time be increased or decreased by adjustments made on the records of the
Trustee or DTC or its nominee, as the case may be, as hereinafter provided.

     SECTION 5.02. Certificate Register; Registration of Transfer and Exchange
of Certificates

          (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 5.09 hereof, a Certificate Register
for the Issuing Entity in which, subject to the provisions of subsections (b)
and (c) below and to such reasonable regulations as it may prescribe, the
Trustee shall provide for the registration of Certificates and of Transfers and
exchanges of Certificates as herein provided. Upon surrender for registration of
Transfer of any Certificate, the Authenticating Agent shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Certificates of the same Class and of like aggregate Percentage Interest.

     At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Trustee. Whenever any Certificates are
so surrendered for exchange, the Trustee shall execute and the Authenticating
Agent shall authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Trustee duly executed
by the holder thereof or his attorney duly authorized in writing.

     No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any Transfer or exchange of Certificates may be required. All

                                      -124-

<PAGE>

Certificates surrendered for registration of Transfer or exchange shall be
canceled and subsequently destroyed by a Trustee in accordance with such
Trustee's customary procedures.

     No Transfer of a Class C or Class P Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a Transfer is to be made in reliance upon an exemption
from the Securities Act and such laws, in order to assure compliance with the
Securities Act and such laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective transferee shall (except with
respect to the initial transfer of a Class C or Class P Certificate by Merrill
Lynch & Co. or, in connection with a transfer of a Class C or Class P
Certificate to the indenture trustee under an Indenture pursuant to which NIM
Notes are issued) each certify to the Trustee in writing the facts surrounding
the Transfer in substantially the form set forth in Exhibit F (the "Transferor
Certificate") and (i) deliver a letter in substantially the form of either
Exhibit G (the "Investment Letter") or Exhibit H (the "Rule 144A Letter") or
(ii) there shall be delivered to the Trustee an Opinion of Counsel that such
Transfer may be made pursuant to an exemption from the Securities Act, which
Opinion of Counsel shall not be an expense of the Depositor or the Trustee. The
Depositor shall provide to any Holder of a Class C or Class P Certificate and
any prospective transferee designated by any such Holder, information regarding
the related Certificates and the Mortgage Loans and such other information as
shall be necessary to satisfy the condition to eligibility set forth in Rule
144A(d)(4) for Transfer of any such Certificate without registration thereof
under the Securities Act pursuant to the registration exemption provided by Rule
144A. The Trustee shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information in the possession of the Trustee regarding the
Certificates, the Mortgage Loans and other matters regarding the Trust Fund as
the Depositor shall reasonably request to meet its obligation under the
preceding sentence. Each Holder of a Class C or Class P Certificate desiring to
effect such Transfer shall, and does hereby agree to, indemnify the Depositor
and the Trustee against any liability that may result if the Transfer is not so
exempt or is not made in accordance with such federal and state laws.

     By acceptance of a Regulation S Global Security, whether upon original
issuance or subsequent transfer, each Holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth thereon and
agrees that it will only transfer such a Certificate as provided herein. In
addition, each Holder of a Regulation S Global Security shall be deemed to have
represented and warranted to the Depositor, the Trustee and any of their
respective successors that: (i) such Person is not a "U.S. person" within the
meaning of Regulation S and was, at the time the buy order was originated,
outside the United States and (ii) such Person understands that such
Certificates have not been registered under the Securities Act and that (x)
until the expiration of the 40-day distribution compliance period (within the
meaning of Regulation S), no offer, sale, pledge or other transfer of such
Certificates or any interest therein shall be made in the United States or to or
for the account or benefit of a U.S. person (each as defined in Regulation S),
(y) if in the future it decides to offer, resell, pledge or otherwise transfer
such Certificates, such Certificates may be offered, resold, pledged or
otherwise transferred only (A) to a person which the seller reasonably believes
is a "qualified institutional buyer" as defined in Rule 144A under the
Securities Act, that is purchasing such Certificates for its own account or for
the account of a qualified institutional buyer to which notice is given that the
transfer is being made in reliance on Rule 144A or (B) in an offshore
transaction (as defined in Regulation S) in compliance with the provisions of
Regulation S, in each case in compliance with the requirements of this
Agreement; and it will notify such transferee of the transfer restrictions
specified in this Section.

                                      -125-

<PAGE>

     No transfer of a Certificate that is neither an ERISA Restricted
Certificate nor a Class R Certificate shall be registered unless the transferee
provides the Trustee with a representation that either (i) such transferee is
not, and is not acting for, on behalf of or with any assets of, an employee
benefit plan or other arrangement subject to Title I of ERISA or plan subject to
Section 4975 of the Code, or (ii) until the termination of the Swap Agreement,
the acquisition and holding of the Certificate are eligible for exemptive relief
under any of Section 408(b)(17) of ERISA or Section 4975(d)(20) of the Code,
Prohibited Transaction Class Exemption ("PTCE") 84-14, PTCE 90-1, PTCE 91-38,
PTCE 95-60 or PTCE 96-23.

     No transfer of an ERISA Restricted Certificate or a Class R Certificate
shall be registered unless the Trustee has received (A) a representation to the
effect that such transferee is not an employee benefit plan subject to Title I
of ERISA, a plan subject to Section 4975 of the Code or a plan subject to any
state, local, federal, non-U.S. or other law substantively similar to the
foregoing provisions of ERISA or the Code ("Similar Law"), and is not directly
or indirectly acquiring the ERISA Restricted Certificate or the Class R
Certificate by, on behalf of, or with any assets of any such plan (collectively,
"Plan"), or (B) solely in the case of ERISA Restricted Certificates, (I) if the
Certificate has been the subject of an ERISA-Qualifying Underwriting, a
representation to the effect that such transferee is an insurance company that
is acquiring the Certificate with assets of an "insurance company general
account," as defined in Section V(e) of Prohibited Transaction Class Exemption
("PTCE") 95-60, and the acquisition and holding of the Certificate are covered
and exempt under Sections I and III of PTCE 95-60, or (II) solely in the case of
an ERISA Restricted Certificate that is a Definitive Certificate, an Opinion of
Counsel satisfactory to the Trustee, and upon which the Trustee shall be
entitled to rely, to the effect that the acquisition and holding of such
Certificate will not constitute or result in a nonexempt prohibited transaction
under Title I of ERISA or Section 4975 of the Code, or a violation of Similar
Law, and will not subject the Trustee, the Servicer or the Depositor to any
obligation in addition to those expressly undertaken in this Agreement, which
Opinion of Counsel shall not be an expense of the Trustee, the Servicer or the
Depositor.

     Except in the case of a Definitive Certificate, the representations set
forth in the two immediately preceding paragraphs of this Subsection 5.02(a),
other than clause (B)(II) in the immediately preceding paragraph, shall be
deemed to have been made to the Trustee by the transferee's acceptance of a
Certificate (or the acceptance by a Certificate Owner of the beneficial interest
in any Class of Certificate).

     Notwithstanding any other provision herein to the contrary, any purported
transfer of a Certificate to or on behalf of a Plan without the delivery to the
Trustee of a representation or an Opinion of Counsel satisfactory to the Trustee
as described above shall be void and of no effect. The Trustee shall not be
under any liability to any Person for any registration or transfer of any
Certificate that is in fact not permitted by this Section 5.02(a), nor shall the
Trustee be under any liability for making any payments due on such Certificate
to the Holder thereof or taking any other action with respect to such Holder
under the provisions of this Agreement so long as the transfer was registered by
the Trustee in accordance with the foregoing requirements. The Trustee shall be
entitled, but not obligated, to recover from any Holder of any Certificate that
was in fact a Plan and that held such Certificate in violation of this Section
5.02(a) all payments made on such Certificate at and after the time it commenced
such holding. Any such payments so recovered shall be paid and delivered to the
last preceding Holder of such Certificate that is not a Plan.

          (b) Each Person who has or who acquires any Ownership Interest in a
Class R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to

                                      -126-

<PAGE>

be bound by the following provisions, and the rights of each Person acquiring
any Ownership Interest in a Class R Certificate are expressly subject to the
following provisions:

          (i) Each Person holding or acquiring any Ownership Interest in a Class
     R Certificate shall be a Permitted Transferee and shall promptly notify the
     Trustee of any change or impending change in its status as a Permitted
     Transferee.

          (ii) No Ownership Interest in a Class R Certificate may be purchased,
     transferred or sold, directly or indirectly, except in accordance with the
     provisions hereof. No Ownership Interest in a Class R Certificate may be
     registered on the Closing Date or thereafter transferred, and the Trustee
     shall not register the Transfer of any Class R Certificate unless, in
     addition to the certificates required to be delivered to the Trustee under
     subparagraph (a) above, the Trustee shall have been furnished with an
     affidavit (a "Transfer Affidavit") of the initial owner or the proposed
     transferee in the form attached hereto as Exhibit E-1 and an affidavit of
     the proposed transferor in the form attached hereto as Exhibit E-2. In the
     absence of a contrary instruction from the transferor of a Class R
     Certificate, declaration (11) in Appendix A of the Transfer Affidavit may
     be left blank. If the transferor requests by written notice to the Trustee
     prior to the date of the proposed transfer that one of the two other forms
     of declaration (11) in Appendix A of the Transfer Affidavit be used, then
     the requirements of this Section 5.02(b)(ii) shall not have been satisfied
     unless the Transfer Affidavit includes such other form of declaration.

          (iii) Each Person holding or acquiring any Ownership Interest in a
     Class R Certificate shall agree (A) to obtain a Transfer Affidavit from any
     other Person to whom such Person attempts to Transfer its Ownership
     Interest in a Class R Certificate, (B) to obtain a Transfer Affidavit from
     any Person for whom such Person is acting as nominee, trustee or agent in
     connection with any Transfer of a Class R Certificate and (C) not to
     Transfer its Ownership Interest in a Class R Certificate or to cause the
     Transfer of an Ownership Interest in a Class R Certificate to any other
     Person if it has actual knowledge that such Person is not a Permitted
     Transferee. Further, no transfer, sale or other disposition of any
     Ownership Interest in a Class R Certificate may be made to a person who is
     not a U.S. Person (within the meaning of section 7701 of the Code) unless
     such person furnishes the transferor and the Trustee with a duly completed
     and effective Internal Revenue Service Form W-8ECI (or any successor
     thereto) and the Trustee consents to such transfer, sale or other
     disposition in writing.

          (iv) Any attempted or purported Transfer of any Ownership Interest in
     a Class R Certificate in violation of the provisions of this Section
     5.02(b) shall be absolutely null and void and shall vest no rights in the
     purported transferee. If any purported transferee shall become a Holder of
     a Class R Certificate in violation of the provisions of this Section
     5.02(b), then the last preceding Permitted Transferee shall be restored to
     all rights as Holder thereof retroactive to the date of registration of
     Transfer of such Class R Certificate. The Trustee shall be under no
     liability to any Person for any registration of Transfer of a Class R
     Certificate that is in fact not permitted by Section 5.02(a) and this
     Section 5.02(b) or for making any payments due on such Certificate to the
     Holder thereof or taking any other action with respect to such Holder under
     the provisions of this Agreement so long as the Transfer was registered
     after receipt of the related Transfer Affidavit. The Trustee shall be
     entitled but not obligated to recover from any Holder of a Class R
     Certificate that was in fact not a Permitted Transferee at the time it
     became a Holder or, at such subsequent time as it became other than a
     Permitted Transferee, all payments made on such Class R Certificate at and
     after either such time. Any such payments so recovered by the Trustee shall

                                      -127-

<PAGE>

     be paid and delivered by the Trustee to the last preceding Permitted
     Transferee of such Certificate.

          (v) At the option of the Holder of the Class R Certificate, the Class
     SWR Interest, the Class LTR Interest and the residual interest in the Upper
     Tier REMIC may be severed and represented by separate certificates (with
     the separate certificate that represents the Residual Interest also
     representing all rights of the Class R Certificate to distributions
     attributable to an interest rate on the Class R Certificate in excess of
     the REMIC Pass-Through Rate); provided, however, that such separate
     certification may not occur until the Trustee receives an Opinion of
     Counsel to the effect that separate certification in the form and manner
     proposed would not result in the imposition of federal tax upon the Issuing
     Entity or any of the REMICs provided for herein or cause any of the REMICs
     provided for herein to fail to qualify as a REMIC; and provided further,
     that the provisions of Sections 5.02(a) and (b) will apply to each such
     separate certificate as if the separate certificate were a Class R
     Certificate. If, as evidenced by an Opinion of Counsel, it is necessary to
     preserve the REMIC status of any of the REMICs provided for herein, the
     Class SWR Interest, the Class LTR Interest and the residual interest in the
     Upper Tier REMIC shall be severed and represented by separate certificates
     (with the separate certificate that represents the Residual Interest also
     representing all rights of the Class R Certificate to distributions
     attributable to an interest rate on the Class R Certificate in excess of
     the REMIC Pass-Through Rate).

     The restrictions on Transfers of a Class R Certificate set forth in this
Section 5.02(b) shall cease to apply (and the applicable portions of the legend
on a Class R Certificate may be deleted) with respect to Transfers occurring
after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel
shall not be an expense of the Issuing Entity, the Trustee or the Depositor, to
the effect that the elimination of such restrictions will not cause any of the
REMICs provided for herein to fail to qualify as a REMIC at any time that the
Certificates are outstanding or result in the imposition of any tax on the
Issuing Entity, any REMIC provided for herein, a Certificateholder or another
Person. Each Person holding or acquiring any Ownership Interest in a Class R
Certificate hereby consents to any amendment of this Agreement that, based on an
Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Class R
Certificate is not transferred, directly or indirectly, to a Person that is not
a Permitted Transferee and (b) to provide for a means to compel the Transfer of
a Class R Certificate that is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

          (c) The transferor of the Class R Certificate shall notify the Trustee
in writing upon the transfer of the Class R Certificate.

          (d) [Reserved].

          (e) The preparation and delivery of all certificates, opinions and
other writings referred to above in this Section 5.02 shall not be an expense of
the Issuing Entity, the Depositor or the Trustee.

     SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates

     If (a) any mutilated Certificate is surrendered to the Trustee or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is

                                      -128-

<PAGE>

delivered to the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Trustee
that such Certificate has been acquired by a bona fide purchaser, the Trustee
shall execute, authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
Class, tenor and Percentage Interest. In connection with the issuance of any new
Certificate under this Section 5.03, the Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Trustee and its counsel) connected therewith. Any replacement Certificate
issued pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time. All
Certificates surrendered to the Trustee under the terms of this Section 5.03
shall be canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

     SECTION 5.04. Persons Deemed Owners

     The Trustee and any agent of the Trustee may treat the Person in whose name
any Certificate is registered as the owner of such Certificate for the purpose
of receiving distributions as provided in this Agreement and for all other
purposes whatsoever, and the Trustee nor any agent of the Trustee, shall be
affected by any notice to the contrary.

     SECTION 5.05. Access to List of Certificateholders' Names and Addresses

     If three or more Certificateholders (a) request such information in writing
from the Trustee, (b) state that such Certificateholders desire to communicate
with other Certificateholders with respect to their rights under this Agreement
or under the Certificates, and (c) provide a copy of the communication that such
Certificateholders propose to transmit or if the Depositor shall request such
information in writing from the Trustee, then the Trustee shall, within ten
Business Days after the receipt of such request, provide the Depositor or such
Certificateholders at such recipients' expense the most recent list of the
Certificateholders of the Issuing Entity held by the Trustee, if any. The
Depositor and every Certificateholder, by receiving and holding a Certificate,
agree that the Trustee shall not be held accountable by reason of the disclosure
of any such information as to the list of the Certificateholders hereunder,
regardless of the source from which such information was derived.

     SECTION 5.06. Book-Entry Certificates

     The Regular Certificates, upon original issuance, shall be issued in the
form of one or more typewritten Certificates representing the Book-Entry
Certificates, to be delivered to the Depository by or on behalf of the
Depositor. The Class C, Class P and Class R Certificates shall be definitive
certificates. The Book-Entry Certificates shall initially be registered on the
Certificate Register in the name of the Depository or its nominee, and no
Certificate Owner of a Book-Entry Certificate will receive a definitive
certificate representing such Certificate Owner's interest in such Certificates,
except as provided in Section 5.08. Unless and until definitive, fully
registered Certificates ("Definitive Certificates") have been issued to the
Certificate Owners of the Book-Entry Certificates pursuant to Section 5.08(a):

          (a) the provisions of this Section shall be in full force and effect;

                                      -129-

<PAGE>

          (b) the Depositor and the Trustee may deal with the Depository and the
Depository Participants for all purposes (including the making of distributions)
as the authorized representative of the respective Certificate Owners of the
Book-Entry Certificates;

          (c) registration of the Book-Entry Certificates may not be transferred
by the Trustee except to another Depository;

          (d) the rights of the respective Certificate Owners of the Book-Entry
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of the Book-Entry Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and until
Definitive Certificates are issued pursuant to Section 5.08, the Depository will
make book-entry transfers among the Depository Participants and receive and
transmit distributions of principal and interest on the related Certificates to
such Depository Participants;

          (e) the Depository may collect its usual and customary fees, charges
and expenses from its Depository Participants;

          (f) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants; and

          (g) to the extent that the provisions of this Section conflict with
any other provisions of this Agreement, the provisions of this Section shall
control.

     For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Certificateholders
evidencing a specified percentage of the aggregate unpaid principal amount of
any Class of Certificates, such direction or consent may be given by Certificate
Owners (acting through the Depository and the Depository Participants) owning
Book-Entry Certificates evidencing the requisite percentage of principal amount
of such Class of Certificates.

     In the event that Definitive Certificates are issued pursuant to Section
5.08(b), clauses (a) through (g) of this Section 5.06 shall continue to be
applicable with respect to all remaining Book-Entry Certificates.

     SECTION 5.07. Notices to Depository

     Whenever any notice or other communication is required to be given to
Certificateholders of the Class with respect to which Book-Entry Certificates
have been issued, unless and until Definitive Certificates shall have been
issued to the related Certificate Owners, the Trustee shall give all such
notices and communications to the Depository.

     SECTION 5.08. Definitive Certificates

          (a) If, after Book-Entry Certificates have been issued with respect to
any Certificates, (a) the Depository or the Depositor advises the Trustee that
the Depository is no longer willing, qualified or able to discharge properly its
responsibilities under the Depository Agreement with respect to such
Certificates and the Trustee or the Depositor is unable to locate a qualified
successor, (b) the Depositor notifies the Trustee and the Depository of its
intent to terminate the book-entry system

                                      -130-

<PAGE>

through the Depository and, upon receipt of notice of such intent from the
Depository, the Certificate Owners of the Book-Entry Certificates agree to
initiate such termination or (c) after the occurrence and continuation of an
Event of Default, Certificate Owners of such Book-Entry Certificates having not
less than 51% of the Voting Rights evidenced by any Class of Book-Entry
Certificates advise the Trustee and the Depository in writing through the
Depository Participants that the continuation of a book-entry system with
respect to Certificates of such Class through the Depository (or its successor)
is no longer in the best interests of the Certificate Owners of such Class, then
the Trustee shall notify all Certificate Owners of such Book-Entry Certificates
of the occurrence of any such event and of the availability of Definitive
Certificates to Certificate Owners of such Class requesting the same. The
Depositor shall provide the Trustee with an adequate inventory of certificates
to facilitate the issuance and transfer of Definitive Certificates. Upon
surrender to the Trustee of any such Certificates by the Depository, accompanied
by registration instructions from the Depository for registration, the
Authenticating Agent shall authenticate and the Trustee shall deliver such
Definitive Certificates. Neither the Depositor nor the Trustee shall be liable
for any delay in delivery of such instructions and each may conclusively rely
on, and shall be protected in relying on, such instructions. Upon the issuance
of such Definitive Certificates, all references herein to obligations imposed
upon or to be performed by the Depository shall be deemed to be imposed upon and
performed by the Trustee, to the extent applicable with respect to such
Definitive Certificates and the Trustee shall recognize the Holders of such
Definitive Certificates as Certificateholders hereunder.

     SECTION 5.09. Maintenance of Office or Agency

     The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies where Certificates may be surrendered
for registration of transfer or exchange. The Trustee initially designates its
offices at 135 South LaSalle Street, Chicago, Illinois 60603, Attention: MLMI
2006-RM4 as offices for such purposes. The Trustee will give prompt written
notice to the Certificateholders of any change in such location of any such
office or agency.

     SECTION 5.10. Authenticating Agents

          (a) One or more Authenticating Agents (each, an "Authenticating
Agent") may be appointed hereunder each of which shall be authorized to act on
behalf of the Trustee in authenticating the Certificates. Wherever reference is
made in this Agreement to the authentication of Certificates by the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be an entity organized and
doing business under the laws of the United States of America or any state
thereof, having a combined capital and surplus of at least $15,000,000,
authorized under such laws to operate a trust business and subject to
supervision or examination by federal or state authorities. If the
Authenticating Agent is a party other than the Trustee, the Trustee shall have
no liability in connection with the performance or failure of performance of the
Authenticating Agent. LaSalle Bank National Association is hereby appointed as
the initial Authenticating Agent. The Trustee shall be the Authenticating Agent
during any such time as no other Authenticating Agent has been appointed and has
not resigned.

          (b) Any Person into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion or consolidation to which any Authenticating Agent shall be a
party, or any Person succeeding to the corporate agency

business of any Authenticating Agent, shall continue to be the Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent.

          (c) Any Authenticating Agent may at any time resign by giving at least
30 days' advance written notice of resignation to the Trustee and the Depositor.
Except with respect to the initial Authenticating Agent, LaSalle Bank National
Association, which shall be the Authenticating Agent for so long as it is the
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the
Depositor. Upon receiving a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance within the provisions of this Section 5.10, the Trustee may appoint a
successor Authenticating Agent, shall give written notice of such appointment to
the Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section 5.10. No
Authenticating Agent shall have responsibility or liability for any action taken
by it as such at the direction of the Trustee.

                                   ARTICLE VI

                         THE DEPOSITOR AND THE SERVICER

     SECTION 6.01. Respective Liabilities of the Depositor and the Servicer

     The Depositor and the Servicer shall each be liable in accordance herewith
only to the extent of the obligations specifically and respectively imposed upon
and undertaken by them herein.

     SECTION 6.02. Merger or Consolidation of the Depositor or the Servicer

     Except as provided in the next paragraph, the Depositor and the Servicer
will each keep in full effect its existence, rights and franchises as a
corporation or banking association under the laws of the United States or under
the laws of one of the States thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its respective duties under this Agreement.

     Any Person into which the Depositor or the Servicer may be merged or
consolidated, or any Person resulting from any merger or consolidation to which
the Depositor or the Servicer shall be a party, or any Person succeeding to the
business of the Depositor or the Servicer, shall be the successor of the
Depositor or the Servicer, as the case may be, hereunder, without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding (except for the
execution of an assumption agreement where such succession is not effected by
operation of law); provided, however, that the successor or surviving Person to
the Servicer shall be qualified to sell mortgage loans to, and to service
mortgage loans on behalf of, Fannie Mae or Freddie Mac.

     SECTION 6.03. Limitation on Liability of the Depositor, the Servicer and
Others

                                      -132-
<PAGE>

     None of the Depositor, the Servicer nor any of the directors, officers,
employees or agents of the Depositor or the Servicer shall be under any
liability to the Issuing Entity or the Certificateholders for any action taken
or for refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Servicer or any such Person against any
breach of representations or warranties made by it herein or protect the
Depositor, the Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or negligence
in the performance of duties or by reason of reckless disregard of obligations
and duties hereunder. The Depositor or the Servicer and any director, officer,
employee or agent of the Depositor or the Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor or the Servicer and any
director, officer, employee or agent of the Depositor or the Servicer shall be
indemnified by the Issuing Entity and held harmless against any loss, liability
or expense, incurred in connection with the performance of their duties under
this Agreement or incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing authority or any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense (i) incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder or (ii) which does not constitute
an "unanticipated expense" within the meaning of Treasury Regulation Section
1.860G-1(b)(3)(ii). Neither the Depositor nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its respective duties hereunder and that in its opinion may
involve it in any expense or liability; provided, however, that any either of
the Depositor or the Servicer in its discretion may undertake any such action
that it may deem necessary or desirable in respect of this Agreement and the
rights and duties of the parties hereto and the interests of the Trustee and the
Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom shall be, expenses, costs and
liabilities of the Issuing Entity, and the Depositor and the Servicer shall be
entitled to be reimbursed therefor out of the Collection Account as provided by
Section 3.08 hereof.

     Notwithstanding anything herein to the contrary, in preparing or furnishing
any reports or certifications pursuant to this Agreement, the Servicer shall be
entitled to rely conclusively on the accuracy of the information or data
provided to it by any other party to the Agreement and shall have no liability
for any errors therein.

     SECTION 6.04. Limitation on Resignation of Servicer

     Subject to the provisions of Section 7.01, the second paragraph of Section
7.02, the second paragraph of Section 6.02 and the following paragraph of this
Section 6.04, the Servicer shall not resign from the obligations and duties
hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination permitting the
resignation of the Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee. No such resignation shall become effective
until the Trustee or a successor servicer reasonably acceptable to the Trustee
is appointed and has assumed the Servicer's responsibilities, duties,
liabilities and obligations hereunder. Any such resignation shall not relieve
the Servicer of any of the obligations specified in Section 7.01 and 7.02 as
obligations that survive the resignation or termination of the Servicer.

     Notwithstanding anything to the contrary in the previous paragraph of this
Section 6.04, the Trustee, the Depositor hereby specifically (i) consent to the
pledge and assignment by the Servicer of all the Servicer's right, title and
interest in, to and under this Agreement to the Servicing Rights Pledgee, if

                                     -133-

<PAGE>

any, for the benefit of certain lenders, and (ii) agree that upon delivery to
the Trustee by the Servicing Rights Pledgee of a letter signed by the Servicer
whereby the Servicer shall resign as Servicer under this Agreement,
notwithstanding anything to the contrary which may be set forth in Section 3.04
above, the Trustee shall appoint the Servicing Rights Pledgee or its designee as
successor servicer, provided that the Servicer's resignation will not be
effective unless, at the time of such appointment, the Servicing Rights Pledgee
or its designee (i) meets the requirements of a successor servicer under Section
7.03 of this Agreement (including being acceptable to the Rating Agencies),
provided, that the consent and approval of the Trustee and the Depositor shall
be deemed to have been given to the Servicing Rights Pledgee or its designee,
and the Servicing Rights Pledgee and its designee are hereby agreed to be
acceptable to the Trustee and the Depositor and (ii) agrees to be subject to the
terms of this Agreement. If, pursuant to any provision hereof, the duties of the
Servicer are transferred to a successor servicer, the entire amount of the
Servicing Fee and other compensation payable to the Servicer pursuant hereto
shall thereafter be payable to such successor servicer.

     SECTION 6.05. Errors and Omissions Insurance; Fidelity Bonds

     The Servicer shall, for so long as it acts as servicer under this
Agreement, obtain and maintain in force (a) a policy or policies of insurance
covering errors and omissions in the performance of its obligations as servicer
hereunder, and (b) a fidelity bond in respect of its officers, employees and
agents. Each such policy or policies and bond shall, together, comply with the
requirements from time to time of Fannie Mae or Freddie Mac for Persons
performing servicing for mortgage loans purchased by Fannie Mae or Freddie Mac.
The Servicer shall provide the Trustee, upon request and reasonable notice, with
copies of such policies and fidelity bond or a certification from the insurance
provider evidencing such policies and fidelity bond. The Servicer may be deemed
to have complied with this provision if an Affiliate of the Servicer has such
errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Servicer. In the event that any such policy or bond ceases to be in effect,
the Servicer shall use its reasonable best efforts to obtain a comparable
replacement policy or bond from an insurer or issuer meeting the requirements
set forth above as of the date of such replacement. Any such policy or fidelity
bond shall by its terms not be cancelable without thirty days' prior written
notice to the Trustee.

                                   ARTICLE VII

                        DEFAULT; TERMINATION OF SERVICER

     SECTION 7.01. Events of Default

     "Event of Default," wherever used herein, means any one of the following
events:

          (i) any failure by the Servicer to (A) make any Advance, (B) deposit
     in the Collection Account or the Certificate Account or (C) remit to the
     Trustee any payment required to be made under the terms of this Agreement,
     which failure shall continue unremedied for three Business Days, (or, only
     with respect to a payment required to be made under Section 4.01 hereof,
     for one Business Day), after the date on which written notice of such
     failure shall have been given to the Servicer by the Trustee or the
     Depositor, or to the Trustee, the Depositor and the Servicer by the Holders
     of Certificates evidencing greater than 50% of the Voting Rights evidenced
     by the Certificates; or

                                     -134-

<PAGE>

          (ii) any failure by the Servicer to observe or perform in any material
     respect any other of the covenants or agreements on the part of the
     Servicer contained in this Agreement or any representation or warranty
     shall prove to be untrue, which failure or breach shall continue unremedied
     for a period of sixty (60) days after the date on which written notice of
     such failure shall have been given to the Servicer, the Trustee and the
     Depositor by the Trustee or the Depositor, or to the Servicer, the Trustee
     and the Depositor by the Holders of Certificates evidencing greater than
     50% of the Voting Rights evidenced by the Certificates; or

          (iii) a decree or order of a court or agency or supervisory authority
     having jurisdiction for the appointment of a receiver or liquidator in any
     insolvency, readjustment of debt, marshaling of assets and liabilities or
     similar proceedings, or for the winding-up or liquidation of its affairs,
     shall have been entered against the Servicer and such decree or order shall
     have remained in force undischarged or unstayed for a period of sixty (60)
     consecutive days; or

          (iv) consent by the Servicer to the appointment of a receiver or
     liquidator in any insolvency, readjustment of debt, marshaling of assets
     and liabilities or similar proceedings of or relating to the Servicer or
     all or substantially all of the property of the Servicer; or

          (v) admission by the Servicer in writing of its inability to pay its
     debts generally as they become due, file a petition to take advantage of,
     or commence a voluntary case under, any applicable insolvency or
     reorganization statute, make an assignment for the benefit of its
     creditors, or voluntarily suspend payment of its obligations; or

          (vi) any failure by the Servicer to duly perform, within the required
     time period, its obligations under Sections 3.17, 3.18 and 3.22 of this
     Agreement, which failure continues unremedied for a period of ten (10) days
     after the date on which written notice of such failure, requiring the same
     to be remedied, shall have been given to the Servicer by the Trustee or any
     other party to this Agreement.

     If an Event of Default shall occur with respect to the Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, the Trustee may, or at the
direction of the Holders of Certificates evidencing greater than 50% of the
Voting Rights evidenced by the Certificates, shall, by notice in writing to the
Servicer (with a copy to each Rating Agency), terminate all of the rights and
obligations of the Servicer under this Agreement and in and to the related
Mortgage Loans and the proceeds thereof, other than its rights as a
Certificateholder hereunder. On or after the receipt by the Servicer of such
written notice, all authority and power of the Servicer hereunder, whether with
respect to the related Mortgage Loans or otherwise, shall pass to and be vested
in the Trustee. To the extent the Event of Default resulted from the failure of
the Servicer to make a required Advance, the Trustee shall thereupon make any
Advance described in Section 4.01 hereof subject to Section 3.04 hereof. The
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. Unless expressly provided in such written
notice, no such termination shall affect any obligation of the Servicer to pay
amounts owed pursuant to Article VIII. The Servicer agrees to cooperate with the
Trustee in effecting the termination of the Servicer's responsibilities and
rights hereunder, including, without limitation, the transfer to the Trustee of
all cash amounts which shall at the time be credited to the Collection Account,
or thereafter be received with respect to the

                                     -135-

<PAGE>

Mortgage Loans. The Servicer and the Trustee shall promptly notify the Rating
Agencies of the occurrence of an Event of Default, such notice to be provided in
any event within two Business Days of such occurrence.

     Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a Scheduled Payment on a Mortgage Loan that was due prior to the notice
terminating the Servicer's rights and obligations as Servicer hereunder and
received after such notice, that portion thereof to which the Servicer would
have been entitled pursuant to Sections 3.08(a), and any other amounts payable
to the Servicer hereunder the entitlement to which arose prior to the
termination of its activities hereunder. Notwithstanding anything herein to the
contrary, upon termination of the Servicer hereunder, any liabilities of the
Servicer which accrued prior to such termination shall survive such termination.

     SECTION 7.02. Trustee to Act; Appointment of Successor

     On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 hereof, the Trustee shall, to the extent provided in
Section 3.04, be the successor to the Servicer in its capacity as servicer under
this Agreement and the transactions set forth or provided for herein and shall
be subject to all the responsibilities, duties and liabilities relating thereto
placed on the Servicer by the terms and provisions hereof and applicable law
including the obligation to make advances pursuant to Section 4.01. As
compensation therefor, subject to the last paragraph of Section 7.01, the
Trustee shall be entitled to all fees, compensation and reimbursement for costs
and expenses that the Servicer would have been entitled to hereunder if the
Servicer had continued to act hereunder. Notwithstanding the foregoing, if the
Trustee has become the successor to the Servicer in accordance with Section 7.01
hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is
prohibited by applicable law from making Advances pursuant to Section 4.01
hereof or if it is otherwise unable to so act, appoint, or petition a court of
competent jurisdiction to appoint, any established mortgage loan servicing
institution and does not adversely affect the then current rating of the
Certificates by each Rating Agency as the successor to the Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Servicer hereunder. Any successor Servicer shall be an institution that
is a Fannie Mae and Freddie Mac approved seller/servicer in good standing, that
has a net worth of at least $15,000,000, and that is willing to service the
Mortgage Loans and executes and delivers to the Depositor and the Trustee an
agreement accepting such delegation and assignment, that contains an assumption
by such Person of the rights, powers, duties, responsibilities, obligations and
liabilities of the Servicer (other than liabilities of the Servicer under
Section 6.03 hereof incurred prior to termination of the Servicer under Section
7.01), with like effect as if originally named as a party to this Agreement; and
provided further that each Rating Agency acknowledges that its rating of the
Certificates in effect immediately prior to such assignment and delegation will
not be qualified or reduced as a result of such assignment and delegation. No
appointment of a successor to the Servicer hereunder shall be effective until
the Trustee shall have consented thereto and written notice of such proposed
appointment shall have been provided by the Trustee to each Certificateholder.
The Trustee shall not resign as servicer until a successor servicer has been
appointed and has accepted such appointment. Pending appointment of a successor
to the Servicer hereunder, the Trustee, unless the Trustee is prohibited by law
from so acting, shall, subject to Section 3.04 hereof, act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
Servicer hereunder. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Neither the

                                     -136-

<PAGE>

Trustee nor any other successor servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof or any failure to perform, or any
delay in performing, any duties or responsibilities hereunder, in either case
caused by the failure of the Servicer to deliver or provide, or any delay in
delivering or providing, any cash, information, documents or records to it.

     Any successor to the Servicer as servicer shall give notice to the
Mortgagors of such change of servicer and shall, during the term of its service
as servicer maintain in force the policy or policies that the Servicer is
required to maintain pursuant to Section 6.05.

     SECTION 7.03. Notification to Certificateholders

          (a) Upon any termination of or appointment of a successor to the
Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, the Depositor and to each Rating Agency.

          (b) Within sixty (60) days after the occurrence of any Event of
Default, the Trustee shall transmit by mail to all Certificateholders and the
Rating Agencies notice of each such Event of Default hereunder known to the
Trustee, unless such Event of Default shall have been cured or waived.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

     SECTION 8.01. Duties of the Trustee

     The Trustee, prior to the occurrence of an Event of Default and after the
curing of all Events of Default that may have occurred, shall undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred and remains uncured, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement and use the same degree of care and skill in its exercise as a prudent
person would exercise or use under the circumstances in the conduct of such
person's own affairs. In case an Event of Default or other default by the
Servicer or the Depositor hereunder shall occur and be continuing, the Trustee
shall, at the written direction of the majority of the Certificateholders, or
may, proceed to protect and enforce its rights and the rights of the
Certificateholders under this Agreement by a suit, action or proceeding in
equity or at law or otherwise, whether for the specific performance of any
covenant or agreement contained in this agreement or in aid of the execution of
any power granted in this Agreement or for the enforcement of any other legal,
equitable or other remedy, as the Trustee, being advised by counsel and subject
to the foregoing, shall deem most effectual to protect and enforce any of the
rights of the Trustee and the Certificateholders.

     The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee that are specifically required to be furnished pursuant to any provision
of this Agreement, shall examine them to determine whether they conform on their
face to the requirements of this Agreement. If any such instrument is found not
to conform on its face to the requirements of this Agreement in a material
manner, the Trustee shall notify the person providing such Agreement of such
non-conformance, and if the instrument is not corrected to the its satisfaction,
the Trustee will provide notice thereof to the Certificateholders and take such
further action as directed by the Certificateholders.

                                     -137-

<PAGE>

     No provision of this Agreement shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own misconduct, its negligent failure to perform its obligations in
compliance with this Agreement, or any liability that would be imposed by reason
of its willful misfeasance or bad faith; provided, however, that:

          (i) prior to the occurrence of an Event of Default, and after the
     curing of all such Events of Default that may have occurred, the duties and
     obligations of the Trustee shall be determined solely by the express
     provisions of this Agreement, the Trustee shall not be liable, individually
     or as Trustee, except for the performance of such duties and obligations as
     are specifically set forth in this Agreement, no implied covenants or
     obligations shall be read into this Agreement against the Trustee and, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Agreement that it reasonably believed in good faith to be genuine and
     to have been duly executed by the proper authorities respecting any matters
     arising hereunder;

          (ii) the Trustee shall not, individually or as Trustee, be liable for
     an error of judgment made in good faith by a Responsible Officer or
     Responsible Officers of the Trustee unless the Trustee was negligent or
     acted in bad faith or with willful misfeasance; and

          (iii) the Trustee shall not be liable, individually or as Trustee,
     with respect to any action taken, suffered or omitted to be taken by it in
     good faith in accordance with the direction of the Holders in accordance
     with this Agreement relating to the time, method and place of conducting
     any proceeding for any remedy available to the Trustee, or exercising any
     trust or power conferred upon the Trustee under this Agreement.

     SECTION 8.02. Certain Matters Affecting the Trustee

          (a) Except as otherwise provided in Section 8.01:

          (i) the Trustee may request and conclusively rely upon and shall be
     fully protected in acting or refraining from acting upon any resolution,
     Officer's Certificate, certificate of auditors or any other certificate,
     statement, instrument, opinion, report, notice, request, consent, order,
     appraisal, bond or other paper or document believed by it to be genuine and
     to have been signed or presented by the proper party or parties;

          (ii) the Trustee may consult with counsel of its choice and any advice
     or Opinion of Counsel shall be full and complete authorization and
     protection in respect of any action taken or suffered or omitted by it
     hereunder in good faith and in accordance with such Opinion of Counsel;

          (iii) the Trustee shall not be liable for any action taken, suffered
     or omitted by it in good faith and believed by it to be authorized or
     within the discretion or rights or powers conferred upon it by this
     Agreement;

          (iv) prior to the occurrence of an Event of Default hereunder and
     after the curing of all Events of Default that may have occurred, the
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,

                                     -138-

     opinion, report, notice, request, consent, order, approval, bond or other
     paper or document, unless requested in writing so to do by the Holders of
     each Class of Certificates evidencing not less than 25% of the Voting
     Rights of such Class;

          (v) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents,
     custodians, accountants or attorneys or independent contractors and the
     Trustee will not be responsible for any misconduct or negligence on the
     part of any other agent, custodian, accountant, attorney or independent
     contractor appointed with due care by it hereunder;

          (vi) the Trustee shall not be required to expend its own funds or
     otherwise incur any financial liability in the performance of any of its
     duties hereunder if it shall have reasonable grounds for believing that
     repayment of such funds or adequate indemnity against such liability is not
     assured to it;

          (vii) the Trustee shall not be liable, individually or as Trustee, for
     any loss on any investment of funds pursuant to this Agreement (other than
     as issuer of the investment security);

          (viii) the Trustee shall not be deemed to have knowledge of an Event
     of Default until a Responsible Officer of the Trustee shall have received
     written notice thereof;

          (ix) the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Agreement or to make any
     investigation of matters arising hereunder or to institute, conduct or
     defend any litigation hereunder or in relation hereto at the request, order
     or direction of any of the Certificateholders, pursuant to the provisions
     of this Agreement, unless the Certificateholders shall have offered to the
     Trustee reasonable security or indemnity satisfactory to it against the
     costs, expenses and liabilities that may be incurred therein or thereby;

          (x) if requested by the Servicer, the Trustee may appoint the Servicer
     as the Trustee's attorney-in-fact in order to carry out and perform certain
     activities that are necessary or appropriate for the servicing and
     administration of the Mortgage Loans pursuant to this Agreement. Such
     appointment shall be evidenced by a power of attorney in such form as may
     be agreed to by the Trustee and the Servicer. The Trustee shall have no
     liability for any action or inaction of the Servicer in connection with
     such power of attorney and the Trustee shall be indemnified by the Servicer
     for all liabilities, costs and expenses incurred by the Trustee in
     connection with the Servicer's use or misuse of such powers of attorney;
     and

          (xi) in order to comply with its duties under the U.S.A. Patriot Act,
     the Trustee shall obtain and verify certain information and documentation
     from the other parties hereto, including but not limited to, such party's
     name, address and other identifying information.

          (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee without
the possession of any of the Certificates, or the production thereof at the
trial or other proceeding relating thereto, and any such suit, action or
proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement. The Trustee shall have no duty (A) to see to any recording,
filing, or depositing of this Agreement or any agreement referred to herein or
any financing statement or continuation statement evidencing a security
interest, or to see to the

                                     -139-

<PAGE>

maintenance of any rerecording, refiling or redepositing, as applicable,
thereof, (B) to see to any insurance or (C) to see to the payment or discharge
of any tax, assessment, or other governmental charge or any lien or encumbrance
of any kind owing with respect to, assessed or levied against, any part of the
Trust Fund.

     SECTION 8.03. Trustee Not Liable for Certificates or Mortgage Loans

     The recitals contained herein shall be taken as the statements of the
Depositor or the Servicer, as the case may be, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representation as to
the validity or sufficiency of this Agreement, of any Mortgage Loan, or any
related document other than with respect to the execution and authentication of
the Certificates, if it so executed or authorized the Certificates. The Trustee
shall not be accountable for the use or application by the Depositor or the
Servicer of any funds paid to the Depositor or the Servicer in respect of the
Mortgage Loans or deposited in or withdrawn from the Collection Account or the
Certificate Account by the Depositor or the Servicer.

     SECTION 8.04. Trustee May Own Certificates

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Certificates with the same rights as it would have if it was not the
Trustee.

     SECTION 8.05. Trustee's Fees and Expenses

     The Trustee and any custodian shall be entitled to, such compensation as
shall be agreed to in writing by the Trustee and the Depositor (which shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust) for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee.

     SECTION 8.06. Indemnification and Expenses of Trustee

          (a) LaSalle Bank National Association (as Trustee and in its
individual corporate capacity) and its directors, officers, employees and agents
shall be entitled to indemnification from the Issuing Entity for any loss,
liability or expense incurred in connection with (i) any audit, controversy or
judicial proceeding relating to a governmental authority or any legal proceeding
incurred without negligence or willful misconduct on their part, arising out of,
or in connection with the acceptance or administration of the trusts created
hereunder and (ii) the performance of their duties hereunder, including any
applicable fees and expenses payable hereunder, and the costs and expenses of
defending themselves against any claim in connection with the exercise or
performance of any of their powers or duties hereunder, provided that:

          (i) with respect to any such claim, the Trustee shall have given the
     Depositor written notice thereof promptly after the Trustee shall have
     knowledge thereof; provided that failure to so notify shall not relieve the
     Issuing Entity of the obligation to indemnify the Trustee; however, any
     reasonable delay by the Trustee to provide written notice to the Depositor
     and the Holders promptly after the Trustee shall have obtained knowledge of
     a claim shall not relieve the Issuing Entity of the obligation to indemnify
     the Trustee under this Section 8.06;

                                     -140-

<PAGE>

          (ii) while maintaining control over its own defense, the Trustee shall
     reasonably cooperate and consult with the Depositor in preparing such
     defense;

          (iii) notwithstanding anything to the contrary in this Section 8.06,
     the Issuing Entity shall not be liable for settlement of any such claim by
     the Trustee entered into without the prior consent of the Depositor, which
     consent shall not be unreasonably withheld or delayed; and

          (iv) indemnification therefor would constitute "unanticipated
     expenses" within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii).

     Any indemnification payments to the Trustee (or a custodian) pursuant to
this Section 8.06(a) shall be allocated first to principal and then, to the
extent remaining, to interest.

     The provisions of this Section 8.06 shall survive any termination of this
Agreement and the resignation or removal of the Trustee and shall be construed
to include, but not be limited to any loss, liability or expense under any
environmental law.

          (b) The Trustee shall be entitled to reimbursement by the Trust Fund
of all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with this Agreement (including fees and expenses of its
counsel and all persons not regularly in its employment), except any such
expenses, disbursements and advances that either (i) arise from its negligence,
bad faith or willful misconduct or (ii) do not constitute "unanticipated
expenses" within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii).

          (c) The Trustee's right to indemnification and reimbursement shall be
subject to a cap of $400,000 in the aggregate in any calendar year, excluding
(i) any Servicing Transfer Costs and (ii) any costs, damages or expenses
incurred by the Trustee in connection with any "high cost" home loans or any
predatory or abusive lending laws, which amounts shall in no case be subject to
any such limitation; provided, however, that such cap shall apply only if NIM
Notes have been issued and shall cease to apply after the date on which any NIM
Notes are paid in full; provided further, however, that amounts incurred by the
Trustee in excess of such annual limit in any calendar year shall be payable to
the Trustee in succeeding calendar years, subject to such annual limit for each
applicable calendar year. Any amounts reimbursable hereunder not in excess of
this cap may be withdrawn by the Trustee from the Certificate Account at any
time.

          (d) Any custodian appointed by the Trustee as herein provided shall be
entitled to indemnification and reimbursement of expenses to the same extent as
the Trustee is entitled to such amounts pursuant to subsection (a) and (b) of
this Section 8.06, without regard to subsection (c) of this Section 8.06.

     SECTION 8.07. Eligibility Requirements for Trustee

     The Trustee hereunder shall, at all times, be a corporation or association
organized and doing business under the laws of a state or the United States of
America, authorized under such laws to exercise corporate trust powers having a
combined capital and surplus of at least $50,000,000, subject to supervision or
examination by federal or state authority and with a credit rating that would
not cause any of the Rating Agencies to reduce their respective ratings of any
Class of Certificates below the ratings issued on the Closing Date (or having
provided such security from time to time as is sufficient to avoid

                                     -141-

<PAGE>

such reduction). If such corporation or association publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 8.07 the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 8.07, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.08 hereof. The corporation or national banking association serving as
Trustee may have normal banking and trust relationships with the Depositor and
its respective Affiliates; provided, however, that such corporation cannot be an
Affiliate of the Servicer.

     SECTION 8.08. Resignation and Removal of Trustee

     The Trustee may at any time resign and be discharged from the trusts hereby
created by (1) giving written notice of resignation to the Depositor by mailing
notice of resignation by first class mail, postage prepaid, to the
Certificateholders at their addresses appearing on the Certificate Register and
each Rating Agency, not less than sixty (60) days before the date specified in
such notice when, subject to Section 8.09, such resignation is to take effect,
and (2) acceptance of appointment by a successor trustee in accordance with
Section 8.09 and meeting the qualifications set forth in Section 8.07. If no
successor trustee shall have been so appointed and have accepted appointment
within thirty (30) days after the giving of such notice or resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

     If at any time (i) the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.07 hereof and shall fail to resign after
written request thereto by the Depositor or (ii) the Trustee shall become
incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Depositor may remove the Trustee and shall promptly appoint a successor trustee
by written instrument, in triplicate, one copy of which instrument shall be
delivered to the Trustee and one copy of which shall be delivered to the
successor trustee.

     The Holders evidencing at least 51% of the Voting Rights of all Classes of
Certificates may at any time remove the Trustee and the Depositor shall appoint
a successor trustee by written instrument or instruments, in triplicate, signed
by such Holders or their attorneys-in-fact duly authorized, one complete set of
which instruments shall be delivered by the successor trustee to the Servicer,
one complete set to the Trustee so removed and one complete set to the successor
so appointed. Notice of any removal of the Trustee shall be given to each Rating
Agency by the successor trustee.

     Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.08 shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 8.09 hereof.

     SECTION 8.09. Successor Trustee

     Any successor trustee appointed as provided in Section 8.08 hereof shall
execute, acknowledge and deliver to the Depositor and to its predecessor trustee
and the Servicer an instrument accepting such appointment hereunder and
thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become fully

                                     -142-

<PAGE>

vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with the like effect as if originally named as trustee herein.

     No successor trustee shall accept appointment as provided in this Section
8.09 unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.07 hereof and its appointment shall
not adversely affect the then current rating of the Certificates.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 8.09, the Depositor shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates. If the Depositor fails to mail such
notice within ten (10) days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Depositor.

     SECTION 8.10. Merger or Consolidation of Trustee

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be eligible under the provisions of Section
8.07 hereof without the execution or filing of any paper or further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding (except for the execution of an assumption agreement where such
succession is not effected by operation of law).

     SECTION 8.11. Appointment of Co-Trustee or Separate Trustee

     Notwithstanding any other provisions of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing any Mortgage Note may at the time be
located, the Servicer and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee to act as co-trustee or co-trustees jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust Fund, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust Fund or any part
thereof, whichever is applicable, and, subject to the other provisions of this
Section 8.11, such powers, duties, obligations, rights and trusts as the
Servicer and the Trustee may consider necessary or desirable. Any such
co-trustee or separate trustee shall be compensated by the Trust Fund and
subject to the written approval of the Servicer. The Trustee shall not be liable
for the actions of any co-trustee appointed with due care; provided that the
appointment of a co-trustee shall not relieve the Trustee of its obligations
hereunder. If the Servicer shall not have joined in such appointment within
fifteen (15) days after the receipt by it of a request to do so, or in the case
an Event of Default shall have occurred and be continuing, the Trustee alone
shall have the power to make such appointment. No co-trustee or separate trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under Section 8.07 and no notice to Certificateholders of the
appointment of any co-trustee or separate trustee shall be required under
Section 8.09.

     Every separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

                                     -143-

<PAGE>

          (i) All rights, powers, duties and obligations conferred or imposed
     upon the Trustee shall be conferred or imposed upon and exercised or
     performed by the Trustee and such separate trustee or co-trustee jointly
     (it being understood that such separate trustee or co-trustee is not
     authorized to act separately without the Trustee joining in such act),
     except to the extent that under any law of any jurisdiction in which any
     particular act or acts are to be performed (whether as Trustee hereunder or
     as successor to the Servicer hereunder), the Trustee shall be incompetent
     or unqualified to perform such act or acts, in which event such rights,
     powers, duties and obligations (including the holding of title to the Trust
     Fund or any portion thereof in any such jurisdiction) shall be exercised
     and performed singly by such separate trustee or co-trustee, but solely at
     the direction of the Trustee;

          (ii) No trustee hereunder shall be held personally liable by reason of
     any act or omission of any other trustee hereunder; and

          (iii) The Trustee may at any time accept the resignation of or remove
     any separate trustee or co-trustee.

     Any notice, request or other writing given to the Trustee shall be deemed
to have been given to each of the then separate trustees and co-trustees, as
effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Depositor.

     Any separate trustee or co-trustee may, at any time, constitute the Trustee
its agent or attorney-in-fact, with full power and authority, to the extent not
prohibited by law, to do any lawful act under or in respect of this Agreement on
its behalf and in its name. If any separate trustee or co-trustee shall die,
become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.

     SECTION 8.12. Tax Matters

          (a) It is intended that each of the REMICs provided for herein shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such REMIC to qualify as, a "real estate mortgage investment conduit"
as defined in and in accordance with the REMIC Provisions. It is also intended
that each of the grantor trusts provided for in Section 2.07 hereof shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such grantor trust to qualify as, a grantor trust under the
provisions of Subpart E, Part I of Subchapter J of the Code. In furtherance of
such intention, the Trustee covenants and agrees that it shall act as agent (and
the Trustee is hereby appointed to act as agent) on behalf of each of the REMICs
provided for herein and that in such capacity it shall: (a) prepare and file, or
cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage
Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by
the Internal Revenue Service) and prepare and file or cause to be prepared and
filed with the Internal Revenue Service and applicable state or local tax
authorities income tax or information returns for each taxable year with

                                     -144-

<PAGE>

respect to each of the REMICs and grantor trusts provided for herein, containing
such information and at the times and in the manner as may be required by the
Code or state or local tax laws, regulations, or rules, and furnish or cause to
be furnished to Certificateholders the schedules, statements or information at
such times and in such manner as may be required thereby; (b) within thirty (30)
days of the Closing Date, furnish or cause to be furnished to the Internal
Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the
name, title, address, and telephone number of the person that the holders of the
Certificates may contact for tax information relating thereto, together with
such additional information as may be required by such Form, and update such
information at the time or times in the manner required by the Code for each of
the REMICs provided for herein; (c) make or cause to be made elections, on
behalf of each of the REMICs provided for herein to be treated as a REMIC on the
federal tax return of such REMICs for their first taxable years (and, if
necessary, under applicable state law); (d) prepare and forward, or cause to be
prepared and forwarded, to the Certificateholders and to the Internal Revenue
Service and, if necessary, state tax authorities, all information returns and
reports as and when required to be provided to them in accordance with the REMIC
Provisions or other applicable law, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Class R Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Person that is not a
Permitted Transferee, or a pass through entity in which a Person that is not a
Permitted Transferee is the record holder of an interest (the reasonable cost of
computing and furnishing such information may be charged to the Person liable
for such tax); (f) to the extent that they are under its control conduct the
affairs of each of the REMICs and grantor trusts provided for herein at all
times that any Certificates are outstanding so as to maintain the status of each
of the REMICs provided for herein as a REMIC under the REMIC Provisions and the
status of each of the grantor trusts provided for herein as a grantor trust
under Subpart E, Part I of Subchapter J of the Code; (g) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any of the REMICs provided for herein or
result in the imposition of tax upon any such REMIC; (h) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the grantor trust status under Subpart E, Part I of Subchapter J
of the Code of any of the grantor trusts provided for herein or result in the
imposition of tax upon any such grantor trust; (i) pay, from the sources
specified in the last paragraph of this Section 8.12(a), the amount of any
federal, state and local taxes, including prohibited transaction taxes as
described below, imposed on each of the REMICs provided for herein prior to the
termination of the Trust Fund when and as the same shall be due and payable (but
such obligation shall not prevent the Trustee or any other appropriate Person
from contesting any such tax in appropriate proceedings and shall not prevent
the Trustee from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (j) sign or cause to be signed federal, state
or local income tax or information returns; (k) maintain records relating to
each of the REMICs provided for herein, including but not limited to the income,
expenses, assets and liabilities of each of the REMICs and grantor trusts
provided for herein; and (l) as and when necessary and appropriate, represent
each of the REMICs provided for herein in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any of
the REMICs provided for herein, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of any of the REMICs provided for herein, and otherwise act on behalf
of each of the REMICs provided for herein in relation to any tax matter
involving any of such REMICs or any controversy involving the Trust Fund.

     In order to enable the Trustee to perform its duties as set forth herein,
the Depositor shall provide, or cause to be provided, to the Trustee within ten
(10) days after the Closing Date all information or data

                                     -145-

<PAGE>

that the Trustee requests in writing and determines to be relevant for tax
purposes to the valuations and offering prices of the Certificates, including,
without limitation, the price, yield, prepayment assumption and projected cash
flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor
shall provide to the Trustee promptly upon written request therefor, any such
additional information or data that the Trustee may, from time to time, request
in order to enable the Trustee to perform its duties as set forth herein. The
Depositor hereby agrees to indemnify the Trustee for any losses, liabilities,
damages, claims or expenses of the Trustee arising from any errors or
miscalculations of the Trustee that result from any failure of the Depositor to
provide, or to cause to be provided, accurate information or data to the Trustee
on a timely basis.

     In the event that any tax is imposed on "prohibited transactions" of any of
the REMICs provided for herein as defined in Section 860F(a)(2) of the Code, on
the "net income from foreclosure property" of any of such REMICs as defined in
Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Trustee, if any such other tax arises out of or results from a breach by
the Trustee of any of its obligations under this Agreement or as a result of the
location of the Trustee, (ii) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or as a result of the
location of such other party or (iii) in all other cases, or in the event that
any liable party here fails to honor its obligations under the preceding clauses
(i) or (ii), any such tax will be paid first with amounts (other than amounts
derived by the Issuing Entity from a payment on any Cap Contract or amounts
received by the Supplemental Interest Trust as payments on the Swap Agreement)
otherwise to be distributed to the Class R Certificateholders (pro rata)
pursuant to Section 4.04, and second with amounts (other than amounts derived by
the Issuing Entity from a payment on any Cap Contract or amounts received by the
Supplemental Interest Trust as payments on the Swap Agreement) otherwise to be
distributed to all other Certificateholders in the following order of priority:
first, to the Class C Certificates (pro rata), second to the Class B-4
Certificates (pro rata), third to the Class B-3 Certificates (pro rata), fourth
to the Class B-2 Certificates (pro rata), fifth to the Class B-1 Certificates
(pro rata), sixth to the Class M-6 Certificates (pro rata), seventh to the Class
M-5 Certificates (pro rata), eighth to the Class M-4 Certificates (pro rata),
ninth to the Class M-3 Certificates (pro rata), tenth to the Class M-2
Certificates (pro rata), eleventh to the Class M-1 Certificates (pro rata) and
twelfth to the Class A Certificates (pro rata). Notwithstanding anything to the
contrary contained herein, to the extent that such tax is payable by the Class R
Certificate, the Trustee is hereby authorized pursuant to such instruction to
retain on any Distribution Date, from the Holders of the Class R Certificate
(and, if necessary, from the Holders of all other Certificates in the priority
specified in the preceding sentence), funds otherwise distributable to such
Holders in an amount sufficient to pay such tax. The Trustee agrees to promptly
notify in writing the party liable for any such tax of the amount thereof and
the due date for the payment thereof.

          (b) Each of the Depositor, the Servicer and the Trustee agrees not to
knowingly or intentionally take any action or omit to take any action that would
cause the termination of the REMIC status of any of the REMICs provided for
herein or result in the imposition of a tax upon any of the REMICs provided for
herein.

                                   ARTICLE IX

                                   TERMINATION

                                     -146-

<PAGE>

     SECTION 9.01. Termination upon Liquidation or Repurchase of all Mortgage
Loans

          (a) Subject to Section 9.03, the obligations and responsibilities of
the Depositor, the Servicer and the Trustee created hereby with respect to the
Trust Fund shall terminate upon the earlier of (a) an Optional Termination and
(b) the later of (i) the maturity or other liquidation (or any Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to this Agreement, as
applicable. In no event shall the trusts created hereby continue beyond the
earlier of (i) the expiration of 21 years from the death of the last survivor of
the descendants of Joseph P. Kennedy, the late Ambassador of the United States
to the Court of St. James's, living on the date hereof and (ii) the Latest
Possible Maturity Date.

          (b) On or before the Determination Date following the Initial Optional
Termination Date, the Trustee shall attempt to terminate the Trust Fund by
conducting an auction of all of the Mortgage Loans and REO Properties via a
solicitation of bids from at least three (3) bidders, each of which shall be a
nationally recognized participant in mortgage finance (the "Auction"). In
addition, the Trustee will also solicit a bid from each Holder of a Class C
Certificate. The Depositor and the Trustee agree to work in good faith to
develop bid procedures in advance of the Initial Optional Termination Date to
govern the operation of the Auction. The Trustee shall be entitled to retain an
investment banking firm and/or other agents in connection with the Auction, the
cost of which shall be included in the Optional Termination Price (unless an
Optional Termination does not occur in which case such costs shall be an expense
of the Trust Fund). The Trustee shall accept the highest bid received at the
Auction; provided that the amount of such bid equals or exceeds the Optional
Termination Price. The Trustee shall determine the Optional Termination Price
based upon information provided by (a) the Servicer with respect to the amounts
described in clauses (i) and (ii) of the definition of "Optional Termination
Price" and (b) the Depositor with respect to the information described in
clauses (iii) and (iv) of the definition of "Optional Termination Price." The
Trustee may conclusively rely upon the information provided to it in accordance
with the immediately preceding sentence and shall not have any liability for the
failure of any party to provide such information. Notwithstanding anything
herein to the contrary, only an amount equal to the Optional Termination Price,
reduced by the portion thereof consisting of the sum of (x) any Swap Termination
Payment and (y) the amount of any unpaid Net Swap Payments that would not
otherwise be funded by the Optional Termination Price but for clause (iv) of the
definition of "Optional Termination Price" (such portion, the "Swap Optional
Termination Payment"), shall be made available for distribution to the
Certificates. The Swap Optional Termination Payment shall be withdrawn by the
Trustee from the Certificate Account and remitted to the Supplemental Interest
Trust for payment to the Swap Counterparty. The Swap Optional Termination
Payment shall not be part of any REMIC and shall not be paid into any account
which is part of any REMIC.

     If an Optional Termination does not occur as a result of the Auction's
failure to achieve the Optional Termination Price, the Servicer may, on any
Distribution Date following such Auction, at its option, terminate the Trust
Fund by purchasing all of the Mortgage Loans and REO Properties at a price equal
to the Optional Termination Price. In connection with such termination, the
Optional Termination Price shall be delivered to the Trustee no later than two
Business Days immediately preceding the related Distribution Date.
Notwithstanding anything to the contrary herein, the Optional Termination Amount
paid to the Trustee by the winning bidder at the Auction or by the Servicer
shall be deposited by the Trustee directly into the Certificate Account
immediately upon receipt. Upon any termination as a result of an Auction, the
Trustee shall, out of the Optional Termination Amount deposited into the
Certificate Account, (x) reimburse the Trustee for its costs and expenses
necessary to conduct the Auction and any

                                     -147-
<PAGE>

other unreimbursed amounts owing to it and (y) pay to the Servicer, the
aggregate amount of any unreimbursed out-of-pocket costs and expenses owed to
the Servicer and any unpaid or unreimbursed Servicing Fees, Advances and
Servicing Advances.

          (c) Notwithstanding anything to the contrary in clause (b) above, in
the event that the Trustee receives the written opinion of a nationally
recognized participant in mortgage finance acceptable to the Sponsor that the
Mortgage Loans and REO Properties to be included in the Auction will not be
saleable at a price sufficient to achieve the Optional Termination Price, the
Trustee need not conduct the Auction. In such event, the Servicer shall have the
option to purchase the Mortgage Loans and REO Properties at the Optional
Termination Price as of the Initial Optional Termination Date.

     SECTION 9.02. Final Distribution on the Certificates

     If on any Determination Date, (i) the Trustee determines that there are no
Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other
than the funds in the Collection Account, the Trustee shall send a final
distribution notice promptly to each Certificateholder or (ii) the Trustee
determines that a Class of Certificates shall be retired after a final
distribution on such Class, the Trustee shall notify the Certificateholders as
soon as practicable after such Determination Date that the final distribution in
retirement of such Class of Certificates is scheduled to be made on the
immediately following Distribution Date. Any final distribution made pursuant to
the immediately preceding sentence will be made only upon presentation and
surrender of the Certificates at the office of the Trustee specified in such
notice.

     Notice of any termination of the Trust Fund, specifying the Distribution
Date on which Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the Trustee
by letter to Certificateholders mailed as soon as practicable after a
determination is made pursuant to the preceding paragraph (or with respect to an
Auction, mailed no later than one Business Day following completion of such
Auction). Any such notice shall specify (a) the Distribution Date upon which
final distribution on the Certificates will be made upon presentation and
surrender of Certificates at the office therein designated, (b) the location of
the office or agency at which such presentation and surrender must be made, and
(c) that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Certificates at the office therein specified. The Trustee will give such notice
to the Swap Counterparty and to each Rating Agency at the time such notice is
given to Certificateholders.

     In the event such notice is given, the Servicer shall remit all funds in
the Collection Account to the Trustee for deposit in the Certificate Account on
the Servicer Remittance Date in an amount equal to the final distribution in
respect of the Certificates. Upon such final deposit and the receipt by the
Trustee of a Request for Release therefor, the Trustee shall promptly release to
the Mortgage Files for the Mortgage Loans.

     Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to Certificateholders of each Class the amounts
allocable to such Certificates held in the Certificate Account in the order and
priority set forth in Section 4.04 hereof on the final Distribution Date and in
proportion to their respective Percentage Interests.

     In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a

                                      -148-

<PAGE>

second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. If within six months after the second notice all the applicable
Certificates shall not have been surrendered for cancellation, the Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining Certificateholders concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds and other
assets that remain a part of the Trust Fund. If within one year after the second
notice all Certificates shall not have been surrendered for cancellation, the
Class R Certificateholders shall be entitled to all unclaimed funds and other
assets of the Trust Fund that remain subject hereto. Upon payment to the Class R
Certificateholders of such funds and assets, the Trustee shall not have any
further duties or obligations with respect thereto.

     SECTION 9.03. Additional Termination Requirements

          (a) In the event the Trustee or the Servicer completes an Optional
Termination as provided in Section 9.01, the Trust Fund shall be terminated in
accordance with the following additional requirements, unless the Trustee has
been supplied with an Opinion of Counsel, at the expense of the Servicer, as
applicable, to the effect that the failure of the Issuing Entity to comply with
the requirements of this Section 9.03 will not (i) result in the imposition of
taxes on "prohibited transactions" of any of the REMICs provided for herein as
defined in Section 860F of the Code, or (ii) cause any of the REMICs provided
for herein to fail to qualify as a REMIC at any time that any Certificates are
outstanding:

          (i) The Depositor shall establish a 90-day liquidation period and
     notify the Trustee thereof, and the Trustee shall in turn specify the first
     day of such period in a statement attached to the final tax returns of each
     of the REMICs provided for herein pursuant to Treasury Regulation Section
     1.860F-1. The Depositor shall satisfy all the requirements of a qualified
     liquidation under Section 860F of the Code and any regulations thereunder,
     as evidenced by an Opinion of Counsel obtained at the expense of the
     Servicer;

          (ii) During such 90-day liquidation period, and at or prior to the
     time of making the final payment on the Certificates, the Depositor as
     agent of the Trustee shall sell all of the assets of the Trust Fund for
     cash; and

          (iii) At the time of the making of the final payment on the
     Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Class R Certificateholders all cash on hand
     (other than cash retained to meet outstanding claims), and the Trust Fund
     shall terminate at that time, whereupon the Trustee shall have no further
     duties or obligations with respect to sums distributed or credited to the
     Class R Certificateholders.

          (b) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Depositor to specify the 90-day liquidation period for the
Trust Fund, which authorization shall be binding upon all successor
Certificateholders.

          (c) The Trustee as agent for each REMIC hereby agrees to adopt and
sign such a plan of complete liquidation prepared and delivered to it by the
Depositor upon the written request of the Depositor, and the receipt of the
Opinion of Counsel referred to in Section 9.03(a) and to take such other action
in connection therewith as may be reasonably requested by the Depositor.

                                      -149-

<PAGE>

          (d) Notwithstanding any other terms of this Agreement, prior to any
termination of the Trust Fund, the Servicer may prepare a reconciliation of all
Advances and Servicing Advances made by it for which it has not been reimbursed
and a reasonable estimate of all additional Servicing Advances and other costs
for which it would be entitled to be reimbursed if the Trust Fund were not being
terminated, including without limitation, any Servicing Advances and other costs
arising under Section 6.03 (Limitation on Liability of the Depositor, the
Servicer and Others), and the Servicer may recover these Advances, Servicing
Advances and estimated Servicing Advances and other costs from the Collection
Account (to the extent that such recovery of Servicing Advances, estimated
Servicing Advances and other costs constitutes "unanticipated expenses" within
the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii)).

          (e) Notwithstanding any other terms of this Agreement, unless the
Servicer previously has notified the Trustee that it has entered into a
servicing agreement for the servicing after the termination date of the Trust
Fund assets, at least twenty (20) days prior to any termination of the Trust
Fund, the Trustee or the Depositor shall notify the Servicer in writing to
transfer the assets of the Trust Fund as of the termination date to the person
specified in the notice, or if such person is not then known, to continue
servicing the assets until the date that is twenty (20) days after the
termination date and on the termination date, the Trustee or the Depositor shall
notify the Servicer of the person to whom the assets should be transferred on
that date. In the latter event the Servicer shall be entitled to recover its
servicing fee and any advances made for the interim servicing period from the
collections on the assets which have been purchased from the Trust and the new
owner of the assets, and the agreements for the new owner to obtain ownership of
the assets of the Trust Fund shall so provide.

                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

     SECTION 10.01. Amendment

     This Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,

          (i) to cure any ambiguity or correct any mistake,

          (ii) to correct, modify or supplement any provision herein which may
     be inconsistent with the Prospectus Supplement or any other provision
     herein,

          (iii) to add any other provisions with respect to matters or questions
     arising under this Agreement, or

          (iv) to modify, alter, amend, add to or rescind any of the terms or
     provisions contained in this Agreement, provided, however, that, in the
     case of clauses (iii) and (iv), such amendment will not, as evidenced by an
     Opinion of Counsel to such effect, adversely affect in any material respect
     the interests of any Holder; provided, further, however, that such
     amendment will be deemed to not adversely affect in any material respect
     the interest of any Holder if the Person requesting such amendment obtains
     a letter from each Rating Agency stating that such amendment will not
     result in a reduction or withdrawal of its rating of any Class of the
     Certificates, it being understood and agreed that any such letter in and of
     itself will not represent a

                                      -150-

<PAGE>

     determination as to the materiality of any such amendment and will
     represent a determination only as to the credit issues affecting any such
     rating. In addition, this Agreement may be amended from time to time by the
     Depositor, the Servicer and the Trustee without the consent of any of the
     Certificateholders and without delivery of an opinion of counsel to comply
     with the provisions of Regulation AB.

     Notwithstanding the foregoing, without the consent of the
Certificateholders, the Depositor, the Servicer and the Trustee may at any time
and from time to time amend this Agreement to modify, eliminate or add to any of
its provisions to such extent as shall be necessary or appropriate to maintain
the qualification of any of the REMICs provided for herein as REMICs under the
Code or to avoid or minimize the risk of the imposition of any tax on the Trust
Fund or any of the REMICs provided for herein pursuant to the Code that would be
a claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee shall have been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such
amendment but in any case shall not be an expense of the Trustee, to the effect
that such action is necessary or appropriate to maintain such qualification or
to avoid or minimize the risk of the imposition of such a tax.

     This Agreement may also be amended from time to time by the Depositor, the
Trustee, the Servicer, the Trustee and the Holders of the Certificates affected
thereby evidencing not less than 66 2/3% of the Voting Rights for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement or of modifying in any manner the rights of the
Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the Holders of Certificates of such Class evidencing 66
2/3% or more of the Voting Rights of such Class or (iii) reduce the aforesaid
percentages of Certificates the Holders of which are required to consent to any
such amendment without the consent of the Holders of all such Certificates then
outstanding.

     Notwithstanding any contrary provision of this Agreement, the Trustee shall
not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not cause the imposition of any
tax on the Trust Fund, any of the REMICs provided for herein or the
Certificateholders or cause any of the REMICs provided for herein to fail to
qualify as a REMIC at any time that any Certificates are outstanding.

     Promptly after the execution of any amendment to this Agreement requiring
the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder and
each Rating Agency.

     It shall not be necessary for the consent of Certificateholders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent shall approve the substance thereof. The manner of
obtaining such consents and of evidencing the authorization of the execution
thereof by Certificateholders shall be subject to such reasonable regulations as
the Trustee may prescribe.

     Nothing in this Agreement shall require the Trustee or the Servicer to
enter into an amendment without receiving an Opinion of Counsel, satisfactory to
the Trustee or the Servicer that (i) such

                                      -151-

<PAGE>

amendment is permitted and is not prohibited by this Agreement and that all
requirements for amending this Agreement have been complied with; and (ii)
either (A) the amendment does not adversely affect in any material respect the
interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 10.01.

     The Trustee may, but shall not be obligated to, enter into any supplement,
modification or waiver which affects its rights, duties or obligations
hereunder.

     The Trustee shall not enter into any amendment to this Agreement that could
have a materially adverse effect on the Swap Counterparty without first
obtaining the consent of the Swap Counterparty and the Trustee shall not enter
into any amendment to this Agreement without first providing notice of such
amendment to the Swap Counterparty.

     Notwithstanding anything to the contrary in this Section 10.01, the Trustee
and the Servicer shall reasonably cooperate with the Depositor and its counsel
to enter into such amendments or modifications to this Agreement as may be
necessary to comply with Regulation AB and any interpretation thereof by the
Securities and Exchange Commission.

     SECTION 10.02. Counterparts

     This Agreement may be executed simultaneously in any number of
counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.

     SECTION 10.03. Governing Law

     THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES
THEREOF.

     SECTION 10.04. Intention of Parties

     It is the express intent of the parties hereto that the conveyance of the
Mortgage Notes, Mortgages, assignments of Mortgages, title insurance policies
and any modifications, extensions and/or assumption agreements and private
mortgage insurance policies relating to the Mortgage Loans by the Depositor to
the Trustee be, and be construed as, an absolute sale thereof to the Trustee. It
is, further, not the intention of the parties that such conveyance be deemed a
pledge thereof by the Depositor to the Trustee. However, in the event that,
notwithstanding the intent of the parties, such assets are held to be the
property of the Depositor, or if for any other reason this Agreement is held or
deemed to create a security interest in such assets, then (i) this Agreement
shall be deemed to be a security agreement within the meaning of the Uniform
Commercial Code of the State of New York and (ii) the conveyance provided for in
this Agreement shall be deemed to be an assignment and a grant by the Depositor
to the Trustee, for the benefit of the Certificateholders, of a security
interest in all of the assets that constitute the Trust Fund, whether now owned
or hereafter acquired.

                                      -152-

<PAGE>

     The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement. The Depositor shall
arrange for filing any Uniform Commercial Code continuation statements in
connection with any security interest granted or assigned to the Trustee for the
benefit of the Certificateholders.

     SECTION 10.05. Notices

          (a) The Trustee shall use its best efforts to promptly provide notice
to each Rating Agency with respect to each of the following of which it has
actual knowledge:

          (i) Any material change or amendment to this Agreement;

          (ii) The occurrence of any Event of Default that has not been cured;

          (iii) The resignation or termination of the Trustee or the Servicer
     and the appointment of any successor;

          (iv) The repurchase or substitution of Mortgage Loans pursuant to
     Sections 2.02 and 2.03;

          (v) The final payment to Certificateholders; and

          (vi) Any change in the location of the Certificate Account.

          (b) The Trustee shall promptly furnish or make available to each
Rating Agency copies of the following:

          (i) Each report to Certificateholders described in Section 4.05;

          (ii) Each annual statement as to compliance described in Section 3.17;

          (iii) Each annual independent public accountants' servicing report
     described in Section 3.18.

                                      -153-

<PAGE>

Certificateholders shall be deemed given when mailed, first class postage
prepaid, to their respective addresses appearing in the Certificate Register.

     SECTION 10.06. Severability of Provisions

     If any one or more of the covenants, agreements, provisions or terms of
this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Certificates or the rights of the Holders thereof.

     SECTION 10.07. Assignment

     Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the
Servicer without the prior written consent of the Trustee and Depositor;
provided, however, the Servicer is hereby authorized to enter into an Advance
Facility under which (l) the Servicer sells, assigns or pledges to an Advancing
Person the Servicer's rights under this Agreement to be reimbursed for any
Advances or Servicing Advances and/or (2) an Advancing Person agrees to fund
some or all Advances or Servicing Advances required to be made by the Servicer
pursuant to this Agreement. No consent of the Trustee, Certificateholders or any
other party is required before the Servicer may enter into an Advance Facility.
Notwithstanding the existence of any Advance Facility under which an Advancing
Person agrees to fund Advances and/or Servicing Advances on the Servicer's
behalf, the Servicer shall remain obligated pursuant to this Agreement to make
Advances and Servicing Advances pursuant to and as required by this Agreement,
and shall not be relieved of such obligations by virtue of such Advance
Facility.

     Reimbursement amounts shall consist solely of amounts in respect of
Advances and/or Servicing Advances made with respect to the Mortgage Loans for
which the Servicer would be permitted to reimburse itself in accordance with
this Agreement, assuming the Servicer had made the related Advance(s) and/or
Servicing Advance(s).

     The Servicer shall maintain and provide to any successor Servicer a
detailed accounting on a loan by loan basis as to amounts advanced by, pledged
or assigned to, and reimbursed to any Advancing Person. The successor Servicer
shall be entitled to rely on any such information provided by the predecessor
Servicer, and the successor Servicer shall not be liable for any errors in such
information.

     An Advancing Person who purchases or receives an assignment or pledge of
the rights to be reimbursed for Advances and/or Servicing Advances, and/or whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the criteria for qualification of a
Subservicer set forth in this Agreement.

     The documentation establishing any Advance Facility shall require that such
reimbursement amounts distributed with respect to each Mortgage Loan be
allocated to outstanding unreimbursed Advances or Servicing Advances (as the
case may be) made with respect to that Mortgage Loan on a "first in, first out"
(FIFO) basis. Such documentation shall also require the Servicer to provide to
the related Advancing Person or its designee loan by loan information with
respect to each such reimbursement amount distributed to such Advancing Person
or Advance Facility trustee on each Distribution Date, to enable the Advancing
Person or Advance Facility trustee to make the FIFO

                                      -154-

<PAGE>

allocation of each such reimbursement amount with respect to each Mortgage Loan.
The Servicer shall remain entitled to be reimbursed by the Advancing Person or
Advance Facility trustee for all Advances and Servicing Advances funded by the
Servicer to the extent the related rights to be reimbursed therefor have not
been sold, assigned or pledged to an Advancing Person.

     Any amendment to this Section 10.07 or to any other provision of this
Agreement that may be necessary or appropriate to effect the terms of an Advance
Facility as described generally in this Section 10.07, including amendments to
add provisions relating to a successor Servicer, may be entered into by the
Trustee and the Servicer, without the consent of any Certificateholder
notwithstanding anything to the contrary in this Agreement, upon receipt by the
Trustee of an Opinion of Counsel that such amendment has no material adverse
effect on the Certificateholders or written confirmation from the Rating
Agencies that such amendment will not adversely affect the ratings on the
Certificates. Prior to entering into an Advance Facility, the Servicer shall
notify the lender under such facility in writing that: (a) the Advances financed
by and/or pledged to the lender are obligations owed to the Servicer on a non
recourse basis payable only from the cash flows and proceeds received under this
Agreement for reimbursement of Advances only to the extent provided herein, and
the Trustee and the Trust Fund are not otherwise obligated or liable to repay
any Advances financed by the lender; (b) the Servicer will be responsible for
remitting to the lender the applicable amounts collected by it as reimbursement
for Advances funded by the lender, subject to the restrictions and priorities
created in this Agreement; and (c) the Trustee shall not have any responsibility
to track or monitor the administration of the financing arrangement between the
Servicer and the lender.

     SECTION 10.08. Limitation on Rights of Certificateholders

     The death or incapacity of any Certificateholder shall not operate to
terminate this Agreement or the Trust Fund, nor entitle such Certificateholder's
legal representative or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a petition or winding up of the Trust
Fund, or otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

     No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth or contained in the terms of the Certificates be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any third
party by reason of any action taken by the parties to this Agreement pursuant to
any provision hereof.

     No Certificateholder shall have any right by virtue or by availing itself
of any provisions of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, the Holders
of Certificates evidencing not less than 25% of the Voting Rights evidenced by
the Certificates shall also have made written request to the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee (individually and as trustee) such
indemnity satisfactory to it as it may require against the costs, expenses, and
liabilities to be incurred therein or thereby, and the Trustee, for sixty (60)
days after its receipt of such notice, request and offer of indemnity shall have
neglected or refused to institute any such action, suit or proceeding; it being
understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner whatever
by virtue or by

                                      -155-

<PAGE>

availing itself or themselves of any provisions of this Agreement to affect,
disturb or prejudice the rights of the Holders of any other of the Certificates,
or to obtain or seek to obtain priority over or preference to any other such
Holder or to enforce any right under this Agreement, except in the manner herein
provided and for the common benefit of all Certificateholders. For the
protection and enforcement of the provisions of this Section 10.08, each and
every Certificateholder and the Trustee shall be entitled to such relief as can
be given either at law or in equity.

     SECTION 10.09. Inspection and Audit Rights

     The Servicer agrees that, on reasonable prior notice, it will permit any
representative of the Depositor or the Trustee during the Servicer's normal
business hours, to examine all the books of account, records, reports and other
papers of the Servicer relating to the Mortgage Loans to make copies and
extracts therefrom, to cause such books to be audited by independent certified
public accountants selected by the Depositor or the Trustee and to discuss its
affairs, finances and accounts relating to the Mortgage Loans with its officers,
employees, agents, counsel and independent public accountants (and by this
provision the Servicer hereby authorizes such accountants to discuss with such
representative such affairs, finances and accounts), all at such reasonable
times and as often as may be reasonably requested. Any out-of-pocket expense
incident to the exercise by the Depositor or the Trustee of any right under this
Section 10.09 shall be borne by the party requesting such inspection (except in
the case of the Trustee in which case such expenses shall be borne by the
requesting Certificateholder(s)); all other such expenses shall be borne by the
Servicer.

     SECTION 10.10. Certificates Nonassessable and Fully Paid

     It is the intention of the Depositor that Certificateholders shall not be
personally liable for obligations of the Issuing Entity, that the interests in
the Issuing Entity represented by the Certificates shall be nonassessable for
any reason whatsoever, and that the Certificates, upon due authentication
thereof by the Authenticating Agent pursuant to this Agreement, are and shall be
deemed fully paid.

     SECTION 10.11. Compliance with Regulation AB

     Each of the parties hereto acknowledges and agrees that the purpose of
Sections 3.17, 3.18 and 3.20 of this Agreement is to facilitate compliance by
the Depositor with the provisions of Regulation AB, as such may be amended or
clarified from time to time. Therefore, each of the parties agrees that (a) the
obligations of the parties hereunder shall be interpreted in such a manner as to
accomplish compliance with Regulation AB, (b) the parties' obligations hereunder
will be supplemented and modified as necessary to be consistent with any such
amendments, interpretive advice or guidance, or convention or consensus among
active participants in the asset-backed securities markets in respect of the
requirements of Regulation AB and (c) the parties shall comply with reasonable
requests made by the Depositor for delivery of that or different information as

Attention: Global Securities and Trust Services - Merrill Lynch Mortgage
           Investors Trust, Series 2006-RM4

Ladies and Gentlemen:

     We propose to purchase Merrill Lynch Mortgage Investors Trust, Mortgage
Loan Asset-Backed Certificates, Series 2006-RM4, Class R, described in the
Prospectus Supplement, dated September 25, 2006, and the Prospectus, dated
September 8, 2006.

     1. We certify that (a) we are not a disqualified organization and (b) we
are not purchasing such Class R Certificate on behalf of a disqualified
organization; for this purpose the term "disqualified organization" means the
United States, any state or political subdivision thereof, any foreign
government, any international organization, any agency or instrumentality of any
of the foregoing (except any entity treated as other than an instrumentality of
the foregoing for purposes of Section 168(h)(2)(D) of the Internal Revenue Code
of 1986, as amended (the "Code")), any organization (other than a cooperative
described in Section 521 of the Code) that is exempt from taxation under the
Code (unless such organization is subject to tax on excess inclusions) and any
organization that is described in Section 1381(a)(2)(C) of the Code. We
understand that any breach by us of this certification may cause us to be liable
for an excise tax imposed upon transfers to disqualified organizations.

     2. We certify that (a) we have historically paid our debts as they became
due, (b) we intend, and believe that we will be able, to continue to pay our
debts as they become due in the future, (c) we understand that, as beneficial
owner of the Class R Certificate, we may incur tax liabilities in excess of any
cash flows generated by the Class R Certificate, and (d) we intend to pay any
taxes associated with holding the Class R Certificate as they become due and (e)
we will not cause income from the Class R Certificate to be attributable to a
foreign permanent establishment or fixed base (within the meaning of an
applicable income tax treaty) of ours or another U.S. taxpayer.

                                       E-1
<PAGE>

     3. We acknowledge that we will be the beneficial owner of the Class R
Certificate and: (1)

     ___________ The Class R Certificate will be registered in our name.

     ___________ The Class R Certificate will be held in the name of our
nominee, _________________, which is not a disqualified organization.

     4. We certify that we are not an employee benefit plan subject to Title I
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), a
plan subject to Section 4975 of the Code or a plan subject to federal, state,
local, non-U.S. or other law substantively similar to the foregoing provisions
of ERISA or the Code (each, a "Plan"), and are not directly or indirectly
acquiring the Class R Certificate on behalf of or with any assets of a Plan.

     5. We certify that (i) we are a U.S. person or (ii) we will hold the Class
R Certificate in connection with the conduct of a trade or business within the
United States and have furnished the transferor and the Trustee with a duly
completed and effective Internal Revenue Service Form W-8ECI or successor form
at the time and in the manner required by the Code; for this purpose the term
"U.S. person" means a citizen or resident of the United States, a corporation,
or partnership (unless, in the case of a partnership, Treasury regulations are
adopted that provide otherwise) created or organized in or under the laws of the
United States, any State thereof or the District of Columbia, including an
entity treated as a corporation or partnership for federal income tax purposes,
an estate whose income is subject to United States federal income tax regardless
of the source of its income, or a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more such U.S. persons have the authority to control all substantial
decisions of the trust (or, to the extent provided in applicable Treasury
regulations, certain trusts in existence on August 20, 1996 which are eligible
to elect to be treated as U.S. Persons). We agree that any breach by us of this
certification shall render the transfer of any interest in the Class R
Certificate to us absolutely null and void and shall cause no rights in the
Class R Certificate to vest in us.

     6. We agree that in the event that at some future time we wish to transfer
any interest in the Class R Certificate, we will transfer such interest in the
Class R Certificate only (a) to a transferee that (i) is not a disqualified
organization and is not purchasing such interest in the Class R Certificate on
behalf of a disqualified organization, (ii) is a U.S. person or will hold the
Class R Certificate in connection with the conduct of a trade or business within
the United States and will furnish us and the Trustee with a duly completed and
effective Internal Revenue Service Form W-8ECI or successor form at the time and
in the manner required by the Code and (iii) has delivered to the Trustee a
letter in the form of this letter (including the affidavit appended hereto) and,
we will provide the Trustee a written statement substantially in the form of
Exhibit E-2 to the Pooling and Servicing Agreement.

the tax matters person for each of the REMICs provided for in the Pooling and
Servicing Agreement.

                                        Very truly yours,

                                        Affidavit pursuant to (i) Section
                                        860E(e)(4) of the Internal Revenue Code
                                        of 1986, as amended, and (ii) certain
                                        provisions of the Pooling and Servicing
                                        Agreement

Under penalties of perjury, the undersigned declares that the following is true:

     1. He or she is an officer of _________________________ (the "Transferee"),

     2. the Transferee's Employer Identification number is __________,

     3. the Transferee is not a "disqualified organization" (as defined below),
has no plan or intention of becoming a disqualified organization, and is not
acquiring any of its interest in the Merrill Lynch Mortgage Investors Trust,
Mortgage Loan Asset-Backed Certificates, Series 2006-RM4, Class R Certificate on
behalf of a disqualified organization or any other entity,

     4. unless Merrill Lynch Mortgage Investors, Inc.("MLMI") has consented to
the transfer to the Transferee by executing the form of Consent affixed as
Appendix B to the Transferee's Letter to which this Certificate is affixed as
Appendix A, the Transferee is a "U.S. person" (as defined below),

     5. that no purpose of the transfer is to avoid or impede the assessment or
collection of tax,

     6. the Transferee has historically paid its debts as they became due,

     7. the Transferee intends, and believes that it will be able, to continue
to pay its debts as they become due in the future,

     8. the Transferee understands that, as beneficial owner of the Class R
Certificate, it may incur tax liabilities in excess of any cash flows generated
by the Class R Certificate,

     9. the Transferee intends to pay any taxes associated with holding the
Class R Certificate as they become due,

     10. the Transferee consents to any amendment of the Pooling and Servicing
Agreement that shall be deemed necessary by Merrill Lynch Mortgage Investors,
Inc. (upon advice of counsel) to constitute a reasonable arrangement to ensure
that the Class R Certificate will not be owned directly or indirectly by a
disqualified organization, and

     11. IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE [the
transfer is not a direct or indirect transfer of the Class R Certificate to a
foreign permanent establishment or fixed base (within the meaning of an
applicable income tax treaty) of the Transferee, and as to each of the residual
interests represented by the Class R Certificate, the present value of the
anticipated tax liabilities associated with holding such residual interest does
not exceed the sum of:

     A. the present value of any consideration given to the Transferee to
acquire such residual interest;

                                       E-4
<PAGE>

     B. the present value of the expected future distributions on such residual
interest; and

     C. the present value of the anticipated tax savings associated with holding
such residual interest as the related REMIC generates losses.

For purposes of this declaration, (i) the Transferee is assumed to pay tax at a
rate equal to the highest rate of tax specified in Section 11(b)(1) of the Code,
but the tax rate specified in Section 55(b)(1)(B) of the Code may be used in
lieu of the highest rate specified in Section 11(b)(1) of the Code if the
Transferee has been subject to the alternative minimum tax under Section 55 of
the Code in the preceding two years and will compute its taxable income in the
current taxable year using the alternative minimum tax rate, and (ii) present
values are computed using a discount rate equal to the Federal short-term rate
prescribed by Section 1274(d) of the Code for the month of the transfer and the
compounding period used by the Transferee;]

[11. (A)  at the time of the transfer, and at the close of each of the
          Transferee's two fiscal years preceding the Transferee's fiscal year
          of transfer, the Transferee's gross assets for financial reporting
          purposes exceed $100 million and its net assets for financial
          reporting purposes exceed $10 million; and

     (B)  the Transferee is an eligible corporation as defined in Treasury
          regulations Section 1.860E-1(c)(6)(i) and has agreed in writing that
          any subsequent transfer of the Class R Certificate will be to another
          eligible corporation in a transaction that satisfies Treasury
          regulation Sections 1.860E-1(c)(4)(i), 1.860E-1(c)(4)(ii),
          1.860E-1(c)(4)(iii) and 1.860E-1(c)(5) and such transfer will not be a
          direct or indirect transfer to a foreign permanent establishment
          (within the meaning of an applicable income tax treaty) of a domestic
          corporation.

For purposes of this declaration, the gross and net assets of the Transferee do
not include any obligation of any related person as defined in Treasury
regulation Section 1.860E-1(c)(6)(ii) or any other asset if a principal purpose
for holding or acquiring the other asset is to permit the Transferee to make
this declaration or to satisfy the requirements of Treasury regulation Section
1.860E-1(c)(5)(i).]

12. The Transferee will not cause income from the Class R Certificate to be
attributable to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.

For purpose of this affidavit, the term "disqualified organization" means the
United States, any state or political subdivision thereof, any foreign
government, any international organization, any agency or instrumentality of any
of the foregoing (except any entity treated as other than an instrumentality of
the foregoing for purposes of Section 168(h)(2)(D) of the Internal Revenue Code
of 1986, as amended (the "Code")), any organization (other than a cooperative
described in Section 521 of the Code) that is exempt from taxation under the
Code (unless such organization is subject to tax on excess inclusions) and any
organization that is described in Section 1381(a)(2)(C) of the Code and the term
"U.S. Person" means a citizen or resident of the United States, a corporation or
partnership (unless, in the case of a partnership, Treasury regulations are
adopted that provide otherwise) created or organized in or under the laws of the
United States, any state thereof or the District of Columbia, including an
entity treated as a corporation or partnership for federal income tax purposes,
an estate whose income is subject to Unites States federal income tax regardless
of its source, or a trust if a court within the United States is able to
exercise primary

     _______________________ (the "Transferor") has reviewed the attached
affidavit of _____________________________ (the "Transferee"), and has no actual
knowledge that such affidavit is not true, and has no reason to believe that the
Transferee has the intention to impede the assessment or collection of any
federal, state or local taxes legally required to be paid with respect to the
Class R Certificate referred to in the attached affidavit. In addition, the
Transferor has conducted a reasonable investigation at the time of the transfer
and found that the Transferee had historically paid its debts as they came due
and found no significant evidence to indicate that the Transferee will not
continue to pay its debts as they become due.

               Counterparty: Not Applicable

          (h)  GOVERNING LAW. The parties to this Agreement hereby agree that
               the law of the State of New York shall govern their rights and
               duties in whole, without regard to conflict of law provisions
               thereof other than New York General Obligations Law Sections
               5-1401 and 5-1402.

          (i)  SEVERABILITY. If any term, provision, covenant, or condition of
               this Agreement, or the application thereof to any party or
               circumstance, shall be held to be invalid or unenforceable (in
               whole or in part) for any reason, the remaining terms,
               provisions, covenants, and conditions hereof shall continue in
               full force and effect as if this Agreement had been executed with
               the invalid or unenforceable portion eliminated, so long as this
               Agreement as so modified continues to express, without material
               change, the original intentions of the parties as to the subject
               matter of this Agreement and the deletion of such portion of this
               Agreement will not substantially impair the respective benefits
               or expectations of the parties.

               The parties shall endeavor to engage in good faith negotiations
               to replace any invalid or unenforceable term, provision, covenant
               or condition with a valid or enforceable term, provision,
               covenant or condition, the economic effect of which

                                      M-1-7

<PAGE>

               comes as close as possible to that of the invalid or
               unenforceable term, provision, covenant or condition.

          (j)  RECORDING OF CONVERSATIONS. Each party (i) consents to the
               recording of telephone conversations between the trading,
               marketing and other relevant personnel of the parties in
               connection with this Agreement or any potential Transaction, (ii)
               agrees to obtain any necessary consent of, and give any necessary
               notice of such recording to, its relevant personnel and (iii)
               agrees, to the extent permitted by applicable law, that
               recordings may be submitted in evidence in any Proceedings.

          (k)  WAIVER OF JURY TRIAL. Each party waives any right it may have to
               a trial by jury in respect of any Proceedings relating to this
               Agreement or any Credit Support Document.

          (l)  NON-RECOURSE. Notwithstanding any provision herein or in the ISDA
               Form Master Agreement to the contrary, the obligations of the
               Counterparty hereunder are limited recourse obligations of the
               Counterparty, payable solely from the Trust Fund and the proceeds
               thereof to satisfy the Counterparty's obligations hereunder. In
               the event that the Trust Fund and proceeds thereof should be
               insufficient to satisfy all claims outstanding and following the
               realization of the Trust Fund and the distribution of the
               proceeds thereof in accordance with the Pooling and Servicing
               Agreement, any claims against or obligations of the Counterparty
               under the ISDA Form Master Agreement or any other confirmation
               thereunder, still outstanding shall be extinguished and
               thereafter not revive. This provision shall survive the
               expiration of this Agreement.

          (m)  LIMITATION ON INSTITUTION OF BANKRUPTCY PROCEEDINGS. BNY shall
               not institute against or cause any other person to institute
               against, or join any other person in instituting against the
               Counterparty, any bankruptcy, reorganization, arrangement,
               insolvency or liquidation proceedings, under any of the laws of
               the United States or any other jurisdiction, for a period of one
               year and one day (or, if longer, the applicable preference
               period) following indefeasible payment in full of the
               Certificates. This provision shall survive the expiration of this
               Agreement.

          (n)  REMEDY OF FAILURE TO PAY OR DELIVER. The ISDA Form Master
               Agreement is hereby amended by replacing the word "third" in the
               third line of Section 5(a)(i) by the word "second".

          (o)  "AFFILIATE" will have the meaning specified in Section 14 of the
               ISDA Form Master Agreement, provided that the Counterparty shall
               not be deemed to have any Affiliates for purposes of this
               Agreement, including for purposes of Section 6(b)(ii).

          (p)  TRUSTEE'S CAPACITY. It is expressly understood and agreed by the
               parties hereto that insofar as this Confirmation is executed by
               the Trustee (i) this Confirmation is executed and delivered by
               LaSalle Bank National Association, not in its individual capacity
               but solely as Trustee pursuant to the Pooling and Servicing
               Agreement in the exercise of the powers and authority conferred
               and vested in it thereunder and pursuant to instruction set forth
               therein (ii) each of the representations, undertakings and
               agreements herein made on behalf of the trust is

                                      M-1-8

<PAGE>

               made and intended not as a personal representation, undertaking
               or agreement of the Trustee but is made and intended for the
               purpose of binding only the Counterparty, and (iii) under no
               circumstances will LaSalle Bank National Association, in its
               individual capacity be personally liable for the payment of any
               indebtedness or expenses or be personally liable for the breach
               or failure of any obligation, representation, warranty or
               covenant made or undertaken under this Confirmation.

          (q)  TRUSTEE'S REPRESENTATION. LaSalle Bank National Association, as
               Trustee, represents and warrants that:

               It has been directed under the Pooling and Servicing Agreement to
               enter into this letter agreement as Trustee on behalf of the
               Counterparty.

          (r)  AMENDMENT TO POOLING AND SERVICING AGREEMENT. Notwithstanding any
               provisions to the contrary in the Pooling and Servicing
               Agreement, none of the Depositor, the Servicer or the Trustee
               shall enter into any amendment thereto which could have a
               material adverse affect on BNY without the prior written consent
               of BNY.

     6)   ADDITIONAL REPRESENTATIONS. Section 3 is hereby amended, by
          substituting for the words "Section 3(f)" in the introductory sentence
          thereof the words "Sections 3(f) and 3(i)" and by adding, at the end
          thereof, the following Sections 3(g), 3(h) and 3(i):

          "(g) RELATIONSHIP BETWEEN PARTIES.

               (1)  NONRELIANCE. It is not relying on any statement or
                    representation of the other party regarding the Transaction
                    (whether written or oral), other than the representations
                    expressly made in this Agreement or the Confirmation in
                    respect of that Transaction.

               (2)  EVALUATION AND UNDERSTANDING.

                    (i)  Each Party acknowledges that LaSalle Bank National
                         Association, has been directed under the Pooling and
                         Servicing Agreement to enter into this Transaction as
                         Trustee on behalf of the Counterparty.

                    (ii) It is acting for its own account and has the capacity
                         to evaluate (internally or through independent
                         professional advice) the Transaction and has made its
                         own decision to enter into the Transaction; it is not
                         relying on any communication (written or oral) of the
                         other party as investment advice or as a recommendation
                         to enter into such transaction; it being understood
                         that information and explanations related to the terms
                         and conditions of such transaction shall not be
                         considered investment advice or a recommendation to
                         enter into such transaction. No communication (written
                         or oral) received from the other party shall be deemed
                         to be an assurance or guarantee as to the expected
                         results of the transaction; and

                                      M-1-9

<PAGE>

                    (iii) It understands the terms, conditions and risks of the
                         Transaction and is willing and able to accept those
                         terms and conditions and to assume (and does, in fact
                         assume) those risks, financially and otherwise.

               (3)  PRINCIPAL. The other party is not acting as a fiduciary or
                    an advisor for it in respect of this Transaction.

          (h)  EXCLUSION FROM COMMODITIES EXCHANGE ACT. (A) It is an "eligible
               contract participant" within the meaning of Section 1a(12) of the
               Commodity Exchange Act, as amended; (B) this Agreement and each
               Transaction is subject to individual negotiation by such party;
               and (C) neither this Agreement nor any Transaction will be
               executed or traded on a "trading facility" within the meaning of
               Section 1a(33) of the Commodity Exchange Act, as amended.

          (i)  ERISA (PENSION PLANS). It is not a pension plan or employee
               benefits plan and it is not using assets of any such plan or
               assets deemed to be assets of such a plan in connection with this
               Transaction.

     7)   SET-OFF. Notwithstanding any provision of this Agreement or any other
          existing or future agreement (but without limiting the provisions of
          Section 2(c) and Section 6, except as provided in the next sentence),
          each party irrevocably waives any and all rights it may have to set
          off, net, recoup or otherwise withhold or suspend or condition payment
          or performance of any obligation between it and the other party
          hereunder against any obligation between it and the other party under
          any other agreements. The last sentence of the first paragraph of
          Section 6(e) shall not apply for purposes of this Transaction.

     8)   ADDITIONAL TERMINATION EVENTS. The following Additional Termination
          Events will apply, in each case with respect to the Counterparty as
          the sole Affected Party (unless otherwise provided below):

          (i)  DOWNGRADE. BNY fails to comply with the Downgrade Provisions as
          set forth in Paragraph 4(9). BNY shall be the sole Affected Party.

          (ii) TERMINATION OF TRUST FUND. The Trust Fund shall be terminated
          pursuant to any provision of the Pooling and Servicing Agreement. The
          Early Termination Date shall be the Distribution Date upon which final
          payment is made in respect of the Certificates.

          (iii) INABILITY TO PAY CLASS A CERTIFICATES. The Trustee is unable to
          pay the Class A Certificates or fails or admits in writing its
          inability to pay the Class A Certificates as they become due.

          (iv) AMENDMENT WITHOUT CONSENT. The Trustee permits the Pooling and
          Servicing Agreement to be amended in a manner which would have a
          material adverse affect on BNY without first obtaining the prior
          written consent of BNY, where such consent is required under the
          Pooling and Servicing Agreement.

          (v)  FAILURE TO PROVIDE INFORMATION REQUIRED BY REGULATION AB. If the
          Depositor under the Pooling and Servicing Agreement still has a
          reporting obligation with respect to this Transaction pursuant to
          Regulation AB under the

                                     M-1-10

<PAGE>

               Securities Act of 1933, as amended, and the Securities Exchange
               Act of 1934, as amended ("REGULATION AB") and BNY has not, within
               30 days after receipt of a Swap Disclosure Request complied with
               the provisions set forth below in this Paragraph 4(8)(v)
               (provided that if the significance percentage reaches 10% after a
               Swap Disclosure Request has been made to BNY, BNY must comply
               with the provisions set forth below in this Section 4(8)(v)
               within 10 days of BNY being informed of the significance
               percentage reaching 10%), then an Additional Termination Event
               shall have occurred with respect to BNY and BNY shall be the sole
               Affected Party with respect to such Additional Termination Event.

               BNY acknowledges that for so long as there are reporting
               obligations with respect to this Transaction under Regulation AB,
               the Depositor is required under Regulation AB to disclose certain
               information set forth in Regulation AB regarding BNY or its group
               of affiliated entities, if applicable, depending on the aggregate
               "significance percentage" of this Agreement and any other
               derivative contracts between BNY or its group of affiliated
               entities, if applicable, and the Counterparty, as calculated from
               time to time in accordance with Item 1115 of Regulation AB.

               If the Depositor determines, reasonably and in good faith, that
               the significance percentage of this Agreement has increased to
               nine (9) percent, then the Depositor may request on a Business
               Day after the date of such determination from BNY the same
               information set forth in Item 1115(b) of Regulation AB that would
               have been required if the significance percentage had in fact
               increased to ten (10) percent (such request, a "SWAP DISCLOSURE
               REQUEST" and such requested information, subject to the last
               sentence of this paragraph, is the "SWAP FINANCIAL DISCLOSURE").
               The Counterparty or the Depositor shall provide BNY with the
               calculations and any other information reasonably requested by
               BNY with respect to the Depositor's determination that led to the
               Swap Disclosure Request. The parties hereto further agree that
               the Swap Financial Disclosure provided to meet the Swap
               Disclosure Request may be, solely at BNY's option, either the
               information set forth in Item 1115(b)(1) or Item 1115(b)(2) of
               Regulation AB.

               Upon the occurrence of a Swap Disclosure Request, BNY, at its own
               expense, shall (x) provide the Depositor with the Swap Financial
               Disclosure, or (y) subject to Rating Agency Confirmation, secure
               another entity to replace BNY as party to this Agreement on terms
               substantially similar to this Agreement which entity is able to
               provide the Swap Financial Disclosure. If permitted by Regulation
               AB, any required Swap Financial Disclosure may be provided by
               incorporation by reference from reports filed pursuant to the
               Securities Exchange Act.

     9)   PROVISIONS RELATING TO DOWNGRADE OF BNY DEBT RATINGS.

     (i)  CERTAIN DEFINITIONS.

               (A) "RATING AGENCY CONDITION" means, with respect to any
               particular proposed act or omission to act hereunder, that the
               Trustee shall have received prior written confirmation from each
               of the applicable Rating Agencies, and shall have provided notice
               thereof to BNY, that the proposed action or inaction would

                                     M-1-11

               not cause a downgrade or withdrawal of their then-current ratings
               of the Certificates.

               (B) "QUALIFYING RATINGS" means, with respect to the debt of any
               assignee or guarantor under Paragraph 4(9)(ii) below,

                    (x) a short-term unsecured and unsubordinated debt rating of

               applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced to "P-2" or below by Moody's and its
                    long-term unsecured and unsubordinated debt is reduced to

     For purposes of (C) and (D) above, such events include those occurring in
     connection with a merger, consolidation or other similar transaction by BNY
     or any applicable credit support provider, but they shall be deemed not to
     occur if, within 30 days (or, in the case of a Ratings Event, 10 Business
     Days) thereafter, each of the applicable Rating Agencies has reconfirmed
     the ratings of the Certificates, as applicable, which were in effect
     immediately prior thereto. For the avoidance of doubt, a downgrade of the
     rating on the Certificates could occur in the event that BNY does not post
     sufficient collateral.

          (ii) ACTIONS TO BE TAKEN UPON OCCURRENCE OF EVENT. Subject, in each
          case set forth in (A) and (B) below, to satisfaction of the Rating
          Agency Condition:

               (A) COLLATERALIZATION EVENT. If a Collateralization Event occurs
               with respect to BNY (or any applicable credit support provider),
               then BNY shall, at its own expense, within thirty (30) days of
               such Collateralization Ratings Event:

                    (1) post collateral under agreements and other instruments
                    approved by the Counterparty, such approval not to be
                    unreasonably withheld, which will be sufficient to restore
                    the immediately prior ratings of the Certificates,

                    (2) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (3) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (4) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of their Certificates.

               (B) RATINGS EVENT. If a Ratings Event occurs with respect to BNY
               (or any applicable credit support provider), then BNY shall, at
               its own expense, within ten (10) Business Days of such Ratings
               Event:

                    (1) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (2) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (3) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates.

     10)  ADDITIONAL PROVISIONS. Notwithstanding the terms of Sections 5 and 6
          of the ISDA Form Master Agreement, if the Counterparty has satisfied
          its payment obligations under Section 2(a)(i) of the ISDA Form Master
          Agreement, and shall, at the time, have no future payment or delivery
          obligation, whether absolute or contingent, then unless BNY is
          required pursuant to appropriate proceedings to return to the
          Counterparty or otherwise returns to the Counterparty upon demand of
          the Counterparty any portion of such payment, (a) the occurrence of an
          event described in Section 5(a) of the ISDA Form

          designate an Early Termination Date pursuant to Section 6 of the ISDA
          Form Master Agreement only as a result of a Termination Event set

     11)  RETURN OF AMOUNTS RECEIVED BY MLML OR ITS AFFILIATES. Merrill Lynch
          Mortgage Lending, Inc. ("MLML") agrees and acknowledges that amounts
          paid hereunder are not intended to benefit the holder of any class of
          certificates rated by any rating agency if such holder is MLML or any

          amounts, it will promptly remit (or, if such amounts are received by
          an affiliate of MLML, MLML hereby agrees that it will cause such
          affiliate to promptly remit) such amounts to the Trustee, whereupon
          such Trustee will promptly remit such amounts to BNY. MLML further
          agrees to provide notice to BNY upon any remittance to the Trustee.

     12)  BNY PAYMENTS TO BE MADE TO TRUSTEE. BNY will, unless otherwise

Ladies and Gentlemen:

     The purpose of this letter agreement ("AGREEMENT") is to confirm the terms
and conditions of the rate Cap Transaction entered into on the Trade Date

trust company duly organized and existing under the laws of the State of New
York, and the Merrill Lynch Mortgage Investors, Inc. Mortgage Loan Asset-Backed

under the Pooling and Servicing Agreement, dated and effective September 1,
2006, among Merrill Lynch Mortgage Investors, Inc., as Depositor, Wilshire
Credit Corporation, as Servicer and LaSalle Bank National Association, as
Trustee (the "POOLING AND SERVICING AGREEMENT"). This Agreement, which evidences
a complete and binding agreement between you and us to enter into the
Transaction on the terms set forth below, constitutes a "CONFIRMATION" as
referred to in the "ISDA FORM MASTER AGREEMENT" (as defined below), as well as a

transaction reference numbers 38360, 38361 and 38363. In the event of any
inconsistency between the provisions of this Agreement and the Definitions or
the ISDA Form Master Agreement, this Agreement shall prevail for purposes of the
Transaction. Capitalized terms not otherwise defined herein or in the
Definitions or the Master Agreement shall have the meaning defined for such term
in the Pooling and Servicing Agreement.

          (i)  SEVERABILITY. If any term, provision, covenant, or condition of
               this Agreement, or the application thereof to any party or
               circumstance, shall be held to be invalid or unenforceable (in
               whole or in part) for any reason, the remaining terms,
               provisions, covenants, and conditions hereof shall continue in
               full force and effect as if this Agreement had been executed with
               the invalid or unenforceable portion eliminated, so long as this
               Agreement as so modified continues to express, without material
               change, the original intentions of the parties as to the subject
               matter of this Agreement and the deletion of such portion of this
               Agreement will not substantially impair the respective benefits

               or condition with a valid or enforceable term, provision,
               covenant or condition, the economic effect of which comes as

               Form Master Agreement to the contrary, the obligations of the
               Counterparty hereunder are limited recourse obligations of the
               Counterparty, payable solely from the Trust Fund and the proceeds
               thereof to satisfy the Counterparty's obligations hereunder. In
               the event that the Trust Fund and proceeds thereof should be
               insufficient to satisfy all claims outstanding and following the
               realization of the Trust Fund and the distribution of the
               proceeds thereof in accordance with the Pooling and Servicing
               Agreement, any claims against or obligations of the Counterparty

               not institute against or cause any other person to institute

               Counterparty, any bankruptcy, reorganization, arrangement,
               insolvency or liquidation proceedings, under any of the laws of
               the United States or any other jurisdiction, for a period of one
               year and one day (or, if longer, the applicable preference
               period) following indefeasible payment in full of the
               Certificates. This provision shall survive the expiration of this
               Agreement.

               Agreement is hereby amended by replacing the word "third" in the
               third line of Section 5(a)(i) by the word "second".

          (o)  "AFFILIATE" will have the meaning specified in Section 14 of the
               ISDA Form Master Agreement, provided that the Counterparty shall
               not be deemed to have any Affiliates for purposes of this
               Agreement, including for purposes of Section 6(b)(ii).

               indebtedness or expenses or be personally liable for the breach
               or failure of any obligation, representation, warranty or

               Counterparty.

          (r)  AMENDMENT TO POOLING AND SERVICING AGREEMENT. Notwithstanding any
               provisions to the contrary in the Pooling and Servicing
               Agreement, none of the Depositor, the Servicer or the Trustee
               shall enter into any amendment thereto which could have a
               material adverse affect on BNY without the prior written consent
               of BNY.

     6)   ADDITIONAL REPRESENTATIONS. Section 3 is hereby amended, by

          thereof, the following Sections 3(g), 3(h) and 3(i):

          "(g) RELATIONSHIP BETWEEN PARTIES.

               (1)  NONRELIANCE. It is not relying on any statement or
                    representation of the other party regarding the Transaction
                    (whether written or oral), other than the representations
                    expressly made in this Agreement or the Confirmation in
                    respect of that Transaction.

               (2)  EVALUATION AND UNDERSTANDING.

                    (i)  Each Party acknowledges that LaSalle Bank National
                         Association, has been directed under the Pooling and
                         Servicing Agreement to enter into this Transaction as
                         Trustee on behalf of the Counterparty.

                    (ii) It is acting for its own account and has the capacity
                         to evaluate (internally or through independent
                         professional advice) the Transaction and has made its
                         own decision to enter into the Transaction; it is not
                         relying on any communication (written or oral) of the
                         other party as investment advice or as a recommendation
                         to enter into such transaction; it being understood
                         that information and explanations related to the terms
                         and conditions of such transaction shall not be
                         considered investment advice or a recommendation to
                         enter into such transaction. No communication (written
                         or oral) received from the other party shall be deemed
                         to be an assurance or guarantee as to the expected
                         results of the transaction; and

                    (iii) It understands the terms, conditions and risks of the
                         Transaction and is willing and able to accept those
                         terms and conditions and to assume (and does, in fact
                         assume) those risks, financially and otherwise.

               (3)  PRINCIPAL. The other party is not acting as a fiduciary or
                    an advisor for it in respect of this Transaction.

          (h)  EXCLUSION FROM COMMODITIES EXCHANGE ACT. (A) It is an "eligible
               contract participant" within the meaning of Section 1a(12) of the
               Commodity Exchange Act, as amended; (B) this Agreement and each
               Transaction is subject to individual negotiation by such party;
               and (C) neither this Agreement nor any Transaction will be
               executed or traded on a "trading facility" within the meaning of
               Section 1a(33) of the Commodity Exchange Act, as amended.

          (i)  ERISA (PENSION PLANS). It is not a pension plan or employee
               benefits plan and it is not using assets of any such plan or
               assets deemed to be assets of such a plan in connection with this
               Transaction.

     7)   SET-OFF. Notwithstanding any provision of this Agreement or any other
          existing or future agreement (but without limiting the provisions of
          Section 2(c) and Section 6, except as provided in the next sentence),
          each party irrevocably waives any and all rights it may have to set
          off, net, recoup or otherwise withhold or suspend or condition payment
          or performance of any obligation between it and the other party
          hereunder against any obligation between it and the other party under
          any other agreements. The last sentence of the first paragraph of
          Section 6(e) shall not apply for purposes of this Transaction.

     8)   ADDITIONAL TERMINATION EVENTS. The following Additional Termination
          Events will apply, in each case with respect to the Counterparty as
          the sole Affected Party (unless otherwise provided below):

          (i)  DOWNGRADE. BNY fails to comply with the Downgrade Provisions as
               set forth in Paragraph 4(9). BNY shall be the sole Affected
               Party.

          (ii) TERMINATION OF TRUST FUND. The Trust Fund shall be terminated
               pursuant to any provision of the Pooling and Servicing Agreement.
               The Early Termination Date shall be the Distribution Date upon
               which final payment is made in respect of the Certificates.

          (iii) INABILITY TO PAY CLASS A CERTIFICATES. The Trustee is unable to
               pay the Class A Certificates or fails or admits in writing its
               inability to pay the Class A Certificates as they become due.

          (iv) AMENDMENT WITHOUT CONSENT. The Trustee permits the Pooling and
               Servicing Agreement to be amended in a manner which would have a
               material adverse affect on BNY without first obtaining the prior
               written consent of BNY, where such consent is required under the
               Pooling and Servicing Agreement.

          (v)  FAILURE TO PROVIDE INFORMATION REQUIRED BY REGULATION AB. If the
               Depositor under the Pooling and Servicing Agreement still has a
               reporting obligation with respect to this Transaction pursuant to
               Regulation AB under the Securities Act of 1933, as amended, and
               the Securities Exchange Act of 1934, as amended ("REGULATION AB")
               and BNY has not, within 30 days after receipt of a Swap
               Disclosure Request complied with the provisions set forth below
               in this Paragraph 4(8)(v) (provided that if the significance
               percentage reaches 10% after a Swap Disclosure Request has been
               made to BNY, BNY must comply with the provisions set forth below
               in this Section 4(8)(v) within 10 days of BNY being informed of
               the significance percentage reaching 10%), then an Additional

                                      M-2-1
<PAGE>

               Termination Event shall have occurred with respect to BNY and BNY
               shall be the sole Affected Party with respect to such Additional
               Termination Event.

               BNY acknowledges that for so long as there are reporting
               obligations with respect to this Transaction under Regulation AB,
               the Depositor is required under Regulation AB to disclose certain
               information set forth in Regulation AB regarding BNY or its group
               of affiliated entities, if applicable, depending on the aggregate
               "significance percentage" of this Agreement and any other
               derivative contracts between BNY or its group of affiliated
               entities, if applicable, and the Counterparty, as calculated from
               time to time in accordance with Item 1115 of Regulation AB.

               If the Depositor determines, reasonably and in good faith, that
               the significance percentage of this Agreement has increased to
               nine (9) percent, then the Depositor may request on a Business
               Day after the date of such determination from BNY the same
               information set forth in Item 1115(b) of Regulation AB that would
               have been required if the significance percentage had in fact
               increased to ten (10) percent (such request, a "SWAP DISCLOSURE
               REQUEST" and such requested information, subject to the last
               sentence of this paragraph, is the "SWAP FINANCIAL DISCLOSURE").
               The Counterparty or the Depositor shall provide BNY with the
               calculations and any other information reasonably requested by
               BNY with respect to the Depositor's determination that led to the
               Swap Disclosure Request. The parties hereto further agree that
               the Swap Financial Disclosure provided to meet the Swap
               Disclosure Request may be, solely at BNY's option, either the
               information set forth in Item 1115(b)(1) or Item 1115(b)(2) of
               Regulation AB.

               Upon the occurrence of a Swap Disclosure Request, BNY, at its own
               expense, shall (x) provide the Depositor with the Swap Financial
               Disclosure, or (y) subject to Rating Agency Confirmation, secure
               another entity to replace BNY as party to this Agreement on terms
               substantially similar to this Agreement which entity is able to
               provide the Swap Financial Disclosure. If permitted by Regulation
               AB, any required Swap Financial Disclosure may be provided by
               incorporation by reference from reports filed pursuant to the
               Securities Exchange Act.

     9)   PROVISIONS RELATING TO DOWNGRADE OF BNY DEBT RATINGS.

     (i)  CERTAIN DEFINITIONS.

               (A) "RATING AGENCY CONDITION" means, with respect to any
               particular proposed act or omission to act hereunder, that the
               Trustee shall have received prior written confirmation from each
               of the applicable Rating Agencies, and shall have provided notice
               thereof to BNY, that the proposed action or inaction would not
               cause a downgrade or withdrawal of their then-current ratings of
               the Certificates.

               (B) "QUALIFYING RATINGS" means, with respect to the debt of any
               assignee or guarantor under Paragraph 4(9)(ii) below,

                    (x) a short-term unsecured and unsubordinated debt rating of
                    "P-1" (not on watch for downgrade), and a long-term
                    unsecured and unsubordinated debt of "A1" (not on watch for
                    downgrade) (or, if it has

                                      M-2-1

<PAGE>

                    no short-term unsecured and unsubordinated debt rating, a
                    long term rating of "Aa3" (not on watch for downgrade) by
                    Moody's, and

                    (y) a short-term unsecured and unsubordinated debt rating of
                    "A-1" by S&P, and

                    (z) a short-term unsecured and unsubordinated debt rating of
                    "F-1" by Fitch.

               (C) A "COLLATERALIZATION EVENT" shall occur with respect to BNY
               (or any applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is reduced to "P-1" (and is on watch for downgrade) or
                    below, and its long-term unsecured and unsubordinated debt
                    is reduced to "A1" (and is on watch for downgrade) or below
                    (or, if it has no short-term unsecured and unsubordinated
                    debt rating, its long term rating is reduced to "Aa3" (and
                    is on watch for downgrade) or below) by Moody's, or

                    (y) its short-term unsecured and unsubordinated debt rating
                    is reduced below "A-1" by S & P; or

                    (z) its short-term unsecured and unsubordinated debt rating
                    is reduced below "F-1" by Fitch.

               (D) A "RATINGS EVENT" shall occur with respect to BNY (or any
               applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced to "P-2" or below by Moody's and its
                    long-term unsecured and unsubordinated debt is reduced to
                    "A3" or below (or, if it has no short-term unsecured and
                    unsubordinated debt rating, its long term rating is reduced
                    to "A2" or below) by Moody's, or

                    (y) its long-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced below "BBB-" by S&P, or

                    (z) its long-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced below "BBB-" by Fitch.

          For purposes of (C) and (D) above, such events include those occurring
          in connection with a merger, consolidation or other similar
          transaction by BNY or any applicable credit support provider, but they
          shall be deemed not to occur if, within 30 days (or, in the case of a
          Ratings Event, 10 Business Days) thereafter, each of the applicable
          Rating Agencies has reconfirmed the ratings of the Certificates, as
          applicable, which were in effect immediately prior thereto. For the
          avoidance of doubt, a downgrade of the rating on the Certificates
          could occur in the event that BNY does not post sufficient collateral.

          (ii) ACTIONS TO BE TAKEN UPON OCCURRENCE OF EVENT. Subject, in each
          case set forth in (A) and (B) below, to satisfaction of the Rating
          Agency Condition:

               (A) COLLATERALIZATION EVENT. If a Collateralization Event occurs
               with respect to BNY (or any applicable credit support provider),
               then BNY shall, at its own expense, within thirty (30) days of
               such Collateralization Ratings Event:

                    (1) post collateral under agreements and other instruments
                    approved by the Counterparty, such approval not to be
                    unreasonably withheld,

                                      M-2-1
<PAGE>

                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates,

                    (2) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (3) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (4) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of their Certificates.

               (B) RATINGS EVENT. If a Ratings Event occurs with respect to BNY
               (or any applicable credit support provider), then BNY shall, at
               its own expense, within ten (10) Business Days of such Ratings
               Event:

                    (1) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (2) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (3) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates.

     10)  ADDITIONAL PROVISIONS. Notwithstanding the terms of Sections 5 and 6
          of the ISDA Form Master Agreement, if the Counterparty has satisfied
          its payment obligations under Section 2(a)(i) of the ISDA Form Master
          Agreement, and shall, at the time, have no future payment or delivery
          obligation, whether absolute or contingent, then unless BNY is
          required pursuant to appropriate proceedings to return to the
          Counterparty or otherwise returns to the Counterparty upon demand of
          the Counterparty any portion of such payment, (a) the occurrence of an
          event described in Section 5(a) of the ISDA Form Master Agreement with
          respect to the Counterparty shall not constitute an Event of Default
          or Potential Event of Default with respect to the Counterparty as the
          Defaulting Party and (b) BNY shall be entitled to designate an Early
          Termination Date pursuant to Section 6 of the ISDA Form Master
          Agreement only as a result of a Termination Event set forth in either
          Section 5(b)(i) or Section 5(b)(ii) of the ISDA Form Master Agreement
          with respect to BNY as the Affected Party or Section 5(b)(iii) of the
          ISDA Form Master Agreement with respect to BNY as the Burdened Party.

                    Counterparty: Not Applicable

          (h)  GOVERNING LAW. The parties to this Agreement hereby agree that
               the law of the State of New York shall govern their rights and
               duties in whole, without regard to conflict of law provisions
               thereof other than New York General Obligations Law Sections
               5-1401 and 5-1402.

          (i)  SEVERABILITY. If any term, provision, covenant, or condition of
               this Agreement, or the application thereof to any party or
               circumstance, shall be held to be invalid or unenforceable (in
               whole or in part) for any reason, the remaining terms,
               provisions, covenants, and conditions hereof shall continue in
               full force and effect as if this Agreement had been executed with
               the invalid or unenforceable portion eliminated, so long as this
               Agreement as so modified continues to express, without material
               change, the original intentions of the parties as to the subject
               matter of this Agreement and the deletion of such portion of this
               Agreement will not substantially impair the respective benefits
               or expectations of the parties.

               The parties shall endeavor to engage in good faith negotiations
               to replace any invalid or unenforceable term, provision, covenant
               or condition with a valid or enforceable term, provision,
               covenant or condition, the economic effect of which comes as
               close as possible to that of the invalid or unenforceable term,
               provision, covenant or condition.

          (j)  RECORDING OF CONVERSATIONS. Each party (i) consents to the
               recording of telephone conversations between the trading,
               marketing and other relevant personnel of the parties in
               connection with this Agreement or any potential Transaction, (ii)
               agrees to obtain any necessary consent of, and give any necessary
               notice of such recording to, its relevant personnel and (iii)
               agrees, to

                                      M-3-1

<PAGE>

               the extent permitted by applicable law, that recordings may be
               submitted in evidence in any Proceedings.

          (k)  WAIVER OF JURY TRIAL. Each party waives any right it may have to
               a trial by jury in respect of any Proceedings relating to this
               Agreement or any Credit Support Document.

          (l)  NON-RECOURSE. Notwithstanding any provision herein or in the ISDA
               Form Master Agreement to the contrary, the obligations of the
               Counterparty hereunder are limited recourse obligations of the
               Counterparty, payable solely from the Trust Fund and the proceeds
               thereof to satisfy the Counterparty's obligations hereunder. In
               the event that the Trust Fund and proceeds thereof should be
               insufficient to satisfy all claims outstanding and following the
               realization of the Trust Fund and the distribution of the
               proceeds thereof in accordance with the Pooling and Servicing
               Agreement, any claims against or obligations of the Counterparty
               under the ISDA Form Master Agreement or any other confirmation
               thereunder, still outstanding shall be extinguished and
               thereafter not revive. This provision shall survive the
               expiration of this Agreement.

          (m)  LIMITATION ON INSTITUTION OF BANKRUPTCY PROCEEDINGS. BNY shall
               not institute against or cause any other person to institute
               against, or join any other person in instituting against the
               Counterparty, any bankruptcy, reorganization, arrangement,
               insolvency or liquidation proceedings, under any of the laws of
               the United States or any other jurisdiction, for a period of one
               year and one day (or, if longer, the applicable preference
               period) following indefeasible payment in full of the
               Certificates. This provision shall survive the expiration of this
               Agreement.

          (n)  REMEDY OF FAILURE TO PAY OR DELIVER. The ISDA Form Master
               Agreement is hereby amended by replacing the word "third" in the
               third line of Section 5(a)(i) by the word "second".

          (o)  "AFFILIATE" will have the meaning specified in Section 14 of the
               ISDA Form Master Agreement, provided that the Counterparty shall
               not be deemed to have any Affiliates for purposes of this
               Agreement, including for purposes of Section 6(b)(ii).

          (p)  TRUSTEE'S CAPACITY. It is expressly understood and agreed by the
               parties hereto that insofar as this Confirmation is executed by
               the Trustee (i) this Confirmation is executed and delivered by
               LaSalle Bank National Association, not in its individual capacity
               but solely as Trustee pursuant to the Pooling and Servicing
               Agreement in the exercise of the powers and authority conferred
               and vested in it thereunder and pursuant to instruction set forth
               therein (ii) each of the representations, undertakings and
               agreements herein made on behalf of the trust is made and
               intended not as a personal representation, undertaking or
               agreement of the Trustee but is made and intended for the purpose
               of binding only the Counterparty, and (iii) under no
               circumstances will LaSalle Bank National Association, in its
               individual capacity be personally liable for the payment of any
               indebtedness or expenses or be personally liable for the breach
               or failure of any obligation, representation, warranty or
               covenant made or undertaken under this Confirmation.

          (q)  TRUSTEE'S REPRESENTATION. LaSalle Bank National Association, as
               Trustee, represents and warrants that:

               It has been directed under the Pooling and Servicing Agreement to
               enter into this letter agreement as Trustee on behalf of the
               Counterparty.

          (r)  AMENDMENT TO POOLING AND SERVICING AGREEMENT. Notwithstanding any
               provisions to the contrary in the Pooling and Servicing
               Agreement, none of the Depositor, the Servicer or the Trustee
               shall enter into any amendment thereto which could have a
               material adverse affect on BNY without the prior written consent
               of BNY.

     6)   ADDITIONAL REPRESENTATIONS. Section 3 is hereby amended, by
          substituting for the words "Section 3(f)" in the introductory sentence
          thereof the words "Sections 3(f) and 3(i)" and by adding, at the end
          thereof, the following Sections 3(g), 3(h) and 3(i):

          "(g) RELATIONSHIP BETWEEN PARTIES.

               (1)  NONRELIANCE. It is not relying on any statement or
                    representation of the other party regarding the Transaction
                    (whether written or oral), other than the representations
                    expressly made in this Agreement or the Confirmation in
                    respect of that Transaction.

               (2)  EVALUATION AND UNDERSTANDING.

                    (i)  Each Party acknowledges that LaSalle Bank National
                         Association, has been directed under the Pooling and
                         Servicing Agreement to enter into this Transaction as
                         Trustee on behalf of the Counterparty.

                    (ii) It is acting for its own account and has the capacity
                         to evaluate (internally or through independent
                         professional advice) the Transaction and has made its
                         own decision to enter into the Transaction; it is not
                         relying on any communication (written or oral) of the
                         other party as investment advice or as a recommendation
                         to enter into such transaction; it being understood
                         that information and explanations related to the terms
                         and conditions of such transaction shall not be
                         considered investment advice or a recommendation to
                         enter into such transaction. No communication (written
                         or oral) received from the other party shall be deemed
                         to be an assurance or guarantee as to the expected
                         results of the transaction; and

                    (iii) It understands the terms, conditions and risks of the
                         Transaction and is willing and able to accept those
                         terms and conditions and to assume (and does, in fact
                         assume) those risks, financially and otherwise.

               (3)  PRINCIPAL. The other party is not acting as a fiduciary or
                    an advisor for it in respect of this Transaction.

                                      M-3-1

<PAGE>

          (h)  EXCLUSION FROM COMMODITIES EXCHANGE ACT. (A) It is an "eligible
               contract participant" within the meaning of Section 1a(12) of the
               Commodity Exchange Act, as amended; (B) this Agreement and each
               Transaction is subject to individual negotiation by such party;
               and (C) neither this Agreement nor any Transaction will be
               executed or traded on a "trading facility" within the meaning of
               Section 1a(33) of the Commodity Exchange Act, as amended.

          (i)  ERISA (PENSION PLANS). It is not a pension plan or employee
               benefits plan and it is not using assets of any such plan or
               assets deemed to be assets of such a plan in connection with this
               Transaction.

     7)   SET-OFF. Notwithstanding any provision of this Agreement or any other
          existing or future agreement (but without limiting the provisions of
          Section 2(c) and Section 6, except as provided in the next sentence),
          each party irrevocably waives any and all rights it may have to set
          off, net, recoup or otherwise withhold or suspend or condition payment
          or performance of any obligation between it and the other party
          hereunder against any obligation between it and the other party under
          any other agreements. The last sentence of the first paragraph of
          Section 6(e) shall not apply for purposes of this Transaction.

     8)   ADDITIONAL TERMINATION EVENTS. The following Additional Termination
          Events will apply, in each case with respect to the Counterparty as
          the sole Affected Party (unless otherwise provided below):

          (i) DOWNGRADE. BNY fails to comply with the Downgrade Provisions as
          set forth in Paragraph 4(9). BNY shall be the sole Affected Party.

          (ii) TERMINATION OF TRUST FUND. The Trust Fund shall be terminated
          pursuant to any provision of the Pooling and Servicing Agreement. The
          Early Termination Date shall be the Distribution Date upon which final
          payment is made in respect of the Certificates.

          (iii) INABILITY TO PAY CLASS A CERTIFICATES. The Trustee is unable to
          pay the Class A Certificates or fails or admits in writing its
          inability to pay the Class A Certificates as they become due.

          (iv) AMENDMENT WITHOUT CONSENT. The Trustee permits the Pooling and
          Servicing Agreement to be amended in a manner which would have a
          material adverse affect on BNY without first obtaining the prior
          written consent of BNY, where such consent is required under the
          Pooling and Servicing Agreement.

          (v) FAILURE TO PROVIDE INFORMATION REQUIRED BY REGULATION AB. If the
          Depositor under the Pooling and Servicing Agreement still has a
          reporting obligation with respect to this Transaction pursuant to
          Regulation AB under the Securities Act of 1933, as amended, and the
          Securities Exchange Act of 1934, as amended ("REGULATION AB") and BNY
          has not, within 30 days after receipt of a Swap Disclosure Request
          complied with the provisions set forth below in this Paragraph 4(8)(v)
          (provided that if the significance percentage reaches 10% after a Swap
          Disclosure Request has been made to BNY, BNY must comply with the
          provisions set forth below in this Section 4(8)(v) within 10 days of
          BNY being informed of the significance percentage reaching 10%), then
          an Additional

                                      M-3-1

<PAGE>

          Termination Event shall have occurred with respect to BNY and BNY
          shall be the sole Affected Party with respect to such Additional
          Termination Event.

          BNY acknowledges that for so long as there are reporting obligations
          with respect to this Transaction under Regulation AB, the Depositor is
          required under Regulation AB to disclose certain information set forth
          in Regulation AB regarding BNY or its group of affiliated entities, if
          applicable, depending on the aggregate "significance percentage" of
          this Agreement and any other derivative contracts between BNY or its
          group of affiliated entities, if applicable, and the Counterparty, as
          calculated from time to time in accordance with Item 1115 of
          Regulation AB.

          If the Depositor determines, reasonably and in good faith, that the
          significance percentage of this Agreement has increased to nine (9)
          percent, then the Depositor may request on a Business Day after the
          date of such determination from BNY the same information set forth in
          Item 1115(b) of Regulation AB that would have been required if the
          significance percentage had in fact increased to ten (10) percent
          (such request, a "SWAP DISCLOSURE REQUEST" and such requested
          information, subject to the last sentence of this paragraph, is the
          "SWAP FINANCIAL DISCLOSURE"). The Counterparty or the Depositor shall
          provide BNY with the calculations and any other information reasonably
          requested by BNY with respect to the Depositor's determination that
          led to the Swap Disclosure Request. The parties hereto further agree
          that the Swap Financial Disclosure provided to meet the Swap
          Disclosure Request may be, solely at BNY's option, either the
          information set forth in Item 1115(b)(1) or Item 1115(b)(2) of
          Regulation AB.

          Upon the occurrence of a Swap Disclosure Request, BNY, at its own
          expense, shall (x) provide the Depositor with the Swap Financial
          Disclosure, or (y) subject to Rating Agency Confirmation, secure
          another entity to replace BNY as party to this Agreement on terms
          substantially similar to this Agreement which entity is able to
          provide the Swap Financial Disclosure. If permitted by Regulation AB,
          any required Swap Financial Disclosure may be provided by
          incorporation by reference from reports filed pursuant to the
          Securities Exchange Act.

     9)   PROVISIONS RELATING TO DOWNGRADE OF BNY DEBT RATINGS.

          (i) CERTAIN DEFINITIONS.

               (A) "RATING AGENCY CONDITION" means, with respect to any
               particular proposed act or omission to act hereunder, that the
               Trustee shall have received prior written confirmation from each
               of the applicable Rating Agencies, and shall have provided notice
               thereof to BNY, that the proposed action or inaction would not
               cause a downgrade or withdrawal of their then-current ratings of
               the Certificates.

               (B) "QUALIFYING RATINGS" means, with respect to the debt of any
               assignee or guarantor under Paragraph 4(9)(ii) below,

                    (x) a short-term unsecured and unsubordinated debt rating of
                    "P-1" (not on watch for downgrade), and a long-term
                    unsecured and unsubordinated debt of "A1" (not on watch for
                    downgrade) (or, if it has

                                      M-3-1

<PAGE>

                    no short-term unsecured and unsubordinated debt rating, a
                    long term rating of "Aa3" (not on watch for downgrade) by
                    Moody's, and

                    (y) a short-term unsecured and unsubordinated debt rating of
                    "A-1" by S&P, and

                    (z) a short-term unsecured and unsubordinated debt rating of
                    "F-1" by Fitch.

               (C) A "COLLATERALIZATION EVENT" shall occur with respect to BNY
               (or any applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is reduced to "P-1" (and is on watch for downgrade) or
                    below, and its long-term unsecured and unsubordinated debt
                    is reduced to "A1" (and is on watch for downgrade) or below
                    (or, if it has no short-term unsecured and unsubordinated
                    debt rating, its long term rating is reduced to "Aa3" (and
                    is on watch for downgrade) or below) by Moody's, or

                    (y) its short-term unsecured and unsubordinated debt rating
                    is reduced below "A-1" by S & P; or

                    (z) its short-term unsecured and unsubordinated debt rating
                    is reduced below "F-1" by Fitch.

               (D) A "RATINGS EVENT" shall occur with respect to BNY (or any
               applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced to "P-2" or below by Moody's and its
                    long-term unsecured and unsubordinated debt is reduced to
                    "A3" or below (or, if it has no short-term unsecured and
                    unsubordinated debt rating, its long term rating is reduced
                    to "A2" or below) by Moody's, or

                    (y) its long-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced below "BBB-" by S&P, or

                    (z) its long-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced below "BBB-" by Fitch.

          For purposes of (C) and (D) above, such events include those occurring
          in connection with a merger, consolidation or other similar
          transaction by BNY or any applicable credit support provider, but they
          shall be deemed not to occur if, within 30 days (or, in the case of a
          Ratings Event, 10 Business Days) thereafter, each of the applicable
          Rating Agencies has reconfirmed the ratings of the Certificates, as
          applicable, which were in effect immediately prior thereto. For the
          avoidance of doubt, a downgrade of the rating on the Certificates
          could occur in the event that BNY does not post sufficient collateral.

          (ii) ACTIONS TO BE TAKEN UPON OCCURRENCE OF EVENT. Subject, in each
          case set forth in (A) and (B) below, to satisfaction of the Rating
          Agency Condition:

               (A) COLLATERALIZATION EVENT. If a Collateralization Event occurs
               with respect to BNY (or any applicable credit support provider),
               then BNY shall, at its own expense, within thirty (30) days of
               such Collateralization Ratings Event:

                    (1) post collateral under agreements and other instruments
                    approved by the Counterparty, such approval not to be
                    unreasonably withheld,

                                      M-3-1

<PAGE>

                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates,

                    (2) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (3) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings;
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (4) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of their Certificates.

               (B) RATINGS EVENT. If a Ratings Event occurs with respect to BNY
               (or any applicable credit support provider), then BNY shall, at
               its own expense, within ten (10) Business Days of such Ratings
               Event:

                    (1) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (2) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (3) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates.

     10)  ADDITIONAL PROVISIONS. Notwithstanding the terms of Sections 5 and 6
          of the ISDA Form Master Agreement, if the Counterparty has satisfied
          its payment obligations under Section 2(a)(i) of the ISDA Form Master
          Agreement, and shall, at the time, have no future payment or delivery
          obligation, whether absolute or contingent, then unless BNY is
          required pursuant to appropriate proceedings to return to the
          Counterparty or otherwise returns to the Counterparty upon demand of
          the Counterparty any portion of such payment, (a) the occurrence of an
          event described in Section 5(a) of the ISDA Form Master Agreement with
          respect to the Counterparty shall not constitute an Event of Default
          or Potential Event of Default with respect to the Counterparty as the
          Defaulting Party and (b) BNY shall be entitled to designate an Early
          Termination Date pursuant to Section 6 of the ISDA Form Master
          Agreement only as a result of a Termination Event set forth in either
          Section 5(b)(i) or Section 5(b)(ii) of the ISDA Form Master Agreement
          with respect to BNY as the Affected Party or Section 5(b)(iii) of the
          ISDA Form Master Agreement with respect to BNY as the Burdened Party.

interest in a Rule 144A Book-Entry Certificate and to effect the transfer
pursuant to Regulation S under the Securities Act of 1933, as amended

          (f)  CREDIT SUPPORT DOCUMENT. Not applicable for either BNY (except
                                        with respect to credit support furnished
                                        pursuant to Paragraph 9) or the
                                        Counterparty.

          (g)  CREDIT SUPPORT PROVIDER.

                    BNY:          Not Applicable (except with respect to credit
                                  support furnished pursuant to Paragraph 9)

                    Counterparty: Not Applicable

          (h)  GOVERNING LAW. The parties to this Agreement hereby agree that
               the law of the State of New York shall govern their rights and
               duties in whole, without regard to conflict of law provisions
               thereof other than New York General Obligations Law Sections
               5-1401 and 5-1402.

          (i)  SEVERABILITY. If any term, provision, covenant, or condition of
               this Agreement, or the application thereof to any party or
               circumstance, shall be held to be invalid or unenforceable (in
               whole or in part) for any reason, the remaining terms,
               provisions, covenants, and conditions hereof shall continue in
               full force and effect as if this Agreement had been executed with
               the invalid or unenforceable portion eliminated, so long as this
               Agreement as so modified continues to express, without material
               change, the original intentions of the parties as to the subject
               matter of this Agreement and the deletion of such portion of this
               Agreement will not substantially impair the respective benefits
               or expectations of the parties.

               The parties shall endeavor to engage in good faith negotiations
               to replace any invalid or unenforceable term, provision, covenant
               or condition with a valid or enforceable term, provision,
               covenant or condition, the economic effect of which comes as
               close as possible to that of the invalid or unenforceable term,
               provision, covenant or condition.

          (j)  RECORDING OF CONVERSATIONS. Each party (i) consents to the
               recording of telephone conversations between the trading,
               marketing and other relevant personnel of the parties in
               connection with this Agreement or any potential Transaction, (ii)
               agrees to obtain any necessary consent of, and give any necessary
               notice of such recording to, its relevant personnel and (iii)
               agrees, to the extent permitted by applicable law, that
               recordings may be submitted in evidence in any Proceedings.

<PAGE>

          (k)  WAIVER OF JURY TRIAL. Each party waives any right it may have to
               a trial by jury in respect of any Proceedings relating to this
               Agreement or any Credit Support Document.

          (l)  NON-RECOURSE. Notwithstanding any provision herein or in the ISDA
               Form Master Agreement to the contrary, the obligations of the
               Counterparty hereunder are limited recourse obligations of the
               Counterparty, payable solely from the Trust Fund and the proceeds
               thereof to satisfy the Counterparty's obligations hereunder. In
               the event that the Trust Fund and proceeds thereof should be
               insufficient to satisfy all claims outstanding, and following the
               realization of the Trust Fund and the distribution of the
               proceeds thereof in accordance with the Pooling and Servicing
               Agreement, any claims against or obligations of the Counterparty
               under the ISDA Form Master Agreement, or any other confirmation
               thereunder, still outstanding shall be extinguished and
               thereafter not revive. This provision shall survive the
               expiration of this Agreement.

          (m)  LIMITATION ON INSTITUTION OF BANKRUPTCY PROCEEDINGS. BNY shall
               not institute against or cause any other person to institute
               against, or join any other person in instituting against the
               Counterparty, any bankruptcy, reorganization, arrangement,
               insolvency or liquidation proceedings, under any of the laws of
               the United States or any other jurisdiction, for a period of one
               year and one day (or, if longer, the applicable preference
               period) following indefeasible payment in full of the
               Certificates. This provision shall survive the expiration of this
               Agreement.

          (n)  REMEDY OF FAILURE TO PAY OR DELIVER. The ISDA Form Master
               Agreement is hereby amended by replacing the word "third" in the
               third line of Section 5(a)(i) by the word "second".

          (o)  "AFFILIATE" will have the meaning specified in Section 14 of the
               ISDA Form Master Agreement, provided that the Counterparty shall
               not be deemed to have any Affiliates for purposes of this
               Agreement, including for purposes of Section 6(b)(ii).

          (p)  TRUSTEE'S CAPACITY. It is expressly understood and agreed by the
               parties hereto that insofar as this Confirmation is executed by
               the Trustee (i) this Confirmation is executed and delivered by
               LaSalle Bank National Association, not in its individual capacity
               but solely as Trustee pursuant to the Pooling and Servicing
               Agreement in the exercise of the powers and authority conferred
               and vested in it thereunder and pursuant to instruction set forth
               therein (ii) each of the representations, undertakings and
               agreements herein made on behalf of the trust is made and
               intended not as a personal representation, undertaking or
               agreement of the Trustee but is made and intended for the purpose
               of binding only the Counterparty, and (iii) under no
               circumstances will LaSalle Bank National Association, in its
               individual capacity be personally liable for the payment of any
               indebtedness or expenses or be personally liable for the breach
               or failure of any obligation, representation, warranty or
               covenant made or undertaken under this Confirmation.

<PAGE>

          (q)  TRUSTEE'S REPRESENTATION. LaSalle Bank National Association, as
               Trustee, represents and warrants that:

               It has been directed under the Pooling and Servicing Agreement to
               enter into this letter agreement as Trustee on behalf of the
               Counterparty.

          (r)  AMENDMENT TO POOLING AND SERVICING AGREEMENT. Notwithstanding any
               provisions to the contrary in the Pooling and Servicing
               Agreement, none of the Depositor, the Servicer or the Trustee
               shall enter into any amendment thereto which could have a
               material adverse affect on BNY without the prior written consent
               of BNY.

     6)   ADDITIONAL REPRESENTATIONS. Section 3 is hereby amended, by
          substituting for the words "Section 3(f)" in the introductory sentence
          thereof the words "Sections 3(f) and 3(i)" and by adding, at the end
          thereof, the following Sections 3(g), 3(h) and 3(i):

          "(g) RELATIONSHIP BETWEEN PARTIES.

               (1) NONRELIANCE. It is not relying on any statement or
               representation of the other party regarding the Transaction
               (whether written or oral), other than the representations
               expressly made in this Agreement or the Confirmation in respect
               of that Transaction.

               (2) EVALUATION AND UNDERSTANDING.

                    (i) Each party acknowledges that LaSalle Bank National
                    Association, has been directed under the Pooling and
                    Servicing Agreement to enter into this Transaction as
                    Trustee on behalf of the Counterparty.

                    (ii) It is acting for its own account and has the capacity
                    to evaluate (internally or through independent professional
                    advice) the Transaction and has made its own decision to
                    enter into the Transaction; it is not relying on any
                    communication (written or oral) of the other party as
                    investment advice or as a recommendation to enter into such
                    transaction; it being understood that information and
                    explanations related to the terms and conditions of such
                    transaction shall not be considered investment advice or a
                    recommendation to enter into such transaction. No
                    communication (written or oral) received from the other
                    party shall be deemed to be an assurance or guarantee as to
                    the expected results of the transaction; and

                    (iii) It understands the terms, conditions and risks of the
                    Transaction and is willing and able to accept those terms
                    and conditions and to assume (and does, in fact assume)
                    those risks, financially and otherwise.

               (3) PRINCIPAL. The other party is not acting as a fiduciary or an
               advisor for it in respect of this Transaction.

                                      Q-10

<PAGE>
          (h)  EXCLUSION FROM COMMODITIES EXCHANGE ACT. (A) It is an "eligible
          contract participant" within the meaning of Section 1a(12) of the
          Commodity Exchange Act, as amended; (B) this Agreement and each
          Transaction is subject to individual negotiation by such party; and
          (C) neither this Agreement nor any Transaction will be executed or
          traded on a "trading facility" within the meaning of Section 1a(33) of
          the Commodity Exchange Act, as amended.

          (i)  ERISA (PENSION PLANS). It is not a pension plan or employee
          benefits plan and it is not using assets of any such plan or assets
          deemed to be assets of such a plan in connection with this
          Transaction.

     7)   SET-OFF. Notwithstanding any provision of this Agreement or any other
          existing or future agreement (but without limiting the provisions of
          Section 2(c) and Section 6, except as provided in the next sentence),
          each party irrevocably waives any and all rights it may have to set
          off, net, recoup or otherwise withhold or suspend or condition payment
          or performance of any obligation between it and the other party
          hereunder against any obligation between it and the other party under
          any other agreements. The last sentence of the first paragraph of
          Section 6(e) shall not apply for purposes of this Transaction.

     8)   ADDITIONAL TERMINATION EVENTS. The following Additional Termination
          Events will apply, in each case with respect to the Counterparty as
          the sole Affected Party (unless otherwise provided below):

          (i)  DOWNGRADE. BNY fails to comply with the Downgrade Provisions as
          set forth in Paragraph 4(9). BNY shall be the sole Affected Party.

          (ii) TERMINATION OF TRUST FUND. The Trust Fund shall be terminated
          pursuant to any provision of the Pooling and Servicing Agreement. The
          Early Termination Date shall be the Distribution Date upon which final
          payment is made in respect of the Certificates.

          (iii) INABILITY TO PAY CLASS A CERTIFICATES. The Trustee is unable to
          pay the Class A Certificates or fails or admits in writing its
          inability to pay the Class A Certificates as they become due.

          (iv) AMENDMENT WITHOUT CONSENT. The Trustee permits the Pooling and
          Servicing Agreement to be amended in a manner which would have a
          material adverse affect on BNY without first obtaining the prior
          written consent of BNY, where such consent is required under the
          Pooling and Servicing Agreement.

          (v)  FAILURE TO PROVIDE INFORMATION REQUIRED BY REGULATION AB. If the
          Depositor under the Pooling and Servicing Agreement still has a
          reporting obligation with respect to this Transaction pursuant to
          Regulation AB under the Securities Act of 1933, as amended, and the
          Securities Exchange Act of 1934, as amended ("REGULATION AB") and BNY
          has not, within 30 days after receipt of a Swap Disclosure Request
          complied with the provisions set forth below in this Paragraph 4(8)(v)
          (provided that if the significance percentage reaches 10% after a Swap
          Disclosure Request has been made to BNY, BNY must comply with the
          provisions set forth below in this Section 4(8)(v) within 10 days of
          BNY being informed of the significance percentage reaching 10%), then
          an Additional

                                      Q-11

<PAGE>

               Termination Event shall have occurred with respect to BNY and BNY
               shall be the sole Affected Party with respect to such Additional
               Termination Event.

               BNY acknowledges that for so long as there are reporting
               obligations with respect to this Transaction under Regulation AB,
               the Depositor is required under Regulation AB to disclose certain
               information set forth in Regulation AB regarding BNY or its group
               of affiliated entities, if applicable, depending on the aggregate
               "significance percentage" of this Agreement and any other
               derivative contracts between BNY or its group of affiliated
               entities, if applicable, and the Counterparty, as calculated from
               time to time in accordance with Item 1115 of Regulation AB.

               If the Depositor determines, reasonably and in good faith, that
               the significance percentage of this Agreement has increased to
               nine (9) percent, then the Depositor may request on a Business
               Day after the date of such determination from BNY the same
               information set forth in Item 1115(b) of Regulation AB that would
               have been required if the significance percentage had in fact
               increased to ten (10) percent (such request, a "SWAP DISCLOSURE
               REQUEST" and such requested information, subject to the last
               sentence of this paragraph, is the "SWAP FINANCIAL DISCLOSURE").
               The Counterparty or the Depositor shall provide BNY with the
               calculations and any other information reasonably requested by
               BNY with respect to the Depositor's determination that led to the
               Swap Disclosure Request. The parties hereto further agree that
               the Swap Financial Disclosure provided to meet the Swap
               Disclosure Request may be, solely at BNY's option, either the
               information set forth in Item 1115(b)(1) or Item 1115(b)(2) of
               Regulation AB.

               Upon the occurrence of a Swap Disclosure Request, BNY, at its own
               expense, shall (x) provide the Depositor with the Swap Financial
               Disclosure, or (y) subject to Rating Agency Confirmation, secure
               another entity to replace BNY as party to this Agreement on terms
               substantially similar to this Agreement which entity is able to
               provide the Swap Financial Disclosure. If permitted by Regulation
               AB, any required Swap Financial Disclosure may be provided by
               incorporation by reference from reports filed pursuant to the
               Securities Exchange Act.

     9)   PROVISIONS RELATING TO DOWNGRADE OF BNY DEBT RATINGS.

     (i)  CERTAIN DEFINITIONS.

               (A) "RATING AGENCY CONDITION" means, with respect to any
               particular proposed act or omission to act hereunder, that the
               Trustee shall have received prior written confirmation from each
               of the applicable Rating Agencies, and shall have provided notice
               thereof to BNY, that the proposed action or inaction would not
               cause a downgrade or withdrawal of their then-current ratings of
               the Certificates.

               (B) "QUALIFYING RATINGS" means, with respect to the debt of any
               assignee or guarantor under Paragraph 4(9)(ii) below,

                    (x) a short-term unsecured and unsubordinated debt rating of

               (C) A "COLLATERALIZATION EVENT" shall occur with respect to BNY
               (or any applicable credit support provider) if:

                    is reduced to "P-1" (and is on watch for downgrade) or
                    below, and its long-term unsecured and unsubordinated debt
                    is reduced to "A1" (and is on watch for downgrade) or below

                    debt rating, its long term rating is reduced to "Aa3" (and
                    is on watch for downgrade) or below) by Moody's, or

                    (y) its short-term unsecured and unsubordinated debt rating
                    is reduced below "A-1" by S & P; or

                    is reduced below "F-1" by Fitch.

               (D) A "RATINGS EVENT" shall occur with respect to BNY (or any
               applicable credit support provider) if:

                    (x) its short-term unsecured and unsubordinated debt rating
                    is withdrawn or reduced to "P-2" or below by Moody's and its
                    long-term unsecured and unsubordinated debt is reduced to
                    "A3" or below (or, if it has no short-term unsecured and
                    unsubordinated debt rating, its long term rating is reduced

                    is withdrawn or reduced below "BBB-" by Fitch.

     For purposes of (C) and (D) above, such events include those occurring in
     connection with a merger, consolidation or other similar transaction by BNY
     or any applicable credit support provider, but they shall be deemed not to
     occur if, within 30 days (or, in the case of a Ratings Event, 10 Business
     Days) thereafter, each of the applicable Rating Agencies has reconfirmed
     the ratings of the Certificates, as applicable, which were in effect
     immediately prior thereto. For the avoidance of doubt, a downgrade of the
     rating on the Certificates could occur in the event that BNY does not post
     sufficient collateral.

     (ii) ACTIONS TO BE TAKEN UPON OCCURRENCE OF EVENT. Subject, in each case
     set forth in (A) and (B) below, to satisfaction of the Rating Agency
     Condition:

                                      Q-13

<PAGE>

               (A) COLLATERALIZATION EVENT. If a Collateralization Event occurs
               with respect to BNY (or any applicable credit support provider),
               then BNY shall, at its own expense, within thirty (30) days of
               such Collateralization Ratings Event:

                    (1) post collateral under agreements and other instruments
                    approved by the Counterparty, such approval not to be
                    unreasonably withheld, which will be sufficient to restore
                    the immediately prior ratings of the Certificates,

                    (2) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (3) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (4) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of their Certificates.

               (B) RATINGS EVENT. If a Ratings Event occurs with respect to BNY
               (or any applicable credit support provider), then BNY shall, at
               its own expense, within ten (10) Business Days of such Ratings
               Event:

                    (1) assign the Transaction to a third party, the ratings of
                    the debt of which (or of the guarantor of which) meet or
                    exceed the Qualifying Ratings, on terms substantially
                    similar to this Confirmation, which party is approved by the
                    Counterparty, such approval not to be unreasonably withheld,

                    (2) obtain a guaranty of, or a contingent agreement of,
                    another person, the ratings of the debt of which (or of the
                    guarantor of which) meet or exceed the Qualifying Ratings,
                    to honor BNY's obligations under this Agreement, provided
                    that such other person is approved by the Counterparty, such
                    approval not to be unreasonably withheld, or

                    (3) establish any other arrangement approved by the
                    Counterparty, such approval not to be unreasonably withheld,
                    which will be sufficient to restore the immediately prior
                    ratings of the Certificates.

     10)  BNY PAYMENTS TO BE MADE TO TRUSTEE. BNY will, unless otherwise
          directed by the Trustee, make all payments hereunder to the Trustee.
          Payment made to the Trustee at the account specified herein or to
          another account specified in writing by the Trustee shall satisfy the
          payment obligations of BNY hereunder to the extent of such payment.

     11)  RETURN OF AMOUNTS RECEIVED BY MLML OR ITS AFFILIATES. Merrill Lynch
          Mortgage Lending, Inc. ("MLML") agrees and acknowledges that amounts
          paid hereunder (except

                                      Q-14

<PAGE>

          for the Additional Fees) are not intended to benefit the holder of any
          class of certificates rated by any rating agency if such holder is
          MLML or any of its affiliates. If MLML or any of its affiliates
          receives any such amounts, it will promptly remit (or, if such amounts
          are received by an affiliate of MLML, MLML hereby agrees that it will
          cause such affiliate to promptly remit) such amounts to the Trustee,
          whereupon such Trustee will promptly remit such amounts to BNY. MLML
          further agrees to provide notice to BNY upon any remittance to the
          Trustee.
