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

Regular Interests and will be evidenced by the Lower Tier REMIC Regular
Interests (which will be uncertificated and will represent the "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 related Seller in the FFFC

(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
     the Group One Mortgage Loans over (ii) the aggregate of the initial
     Certificate Principal Balances of Certificate Group One.

(4)  The initial principal balance of the Class LTII1B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group One
     Mortgage Loans.

(5)  The initial principal balance of the Class LTII2A Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of

     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 II Marker Interests.

(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


                                      -7-

<PAGE>

     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.

                                   DEFINITIONS

     Whenever used in this Agreement, the following words and phrases, unless
the context otherwise requires, shall have the following meanings:

     Accepted Servicing Practices: The Servicer's normal servicing practices,

with respect to the SWAP REMIC Regular Interests and any Distribution Date, the
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 that is 150 days
delinquent or more (whether or not the Mortgage Loan has been converted to an
REO Property), (ii) shortfalls in principal and interest due to bankruptcy
proceedings, the application of the Relief Act or similar laws or certain
permitted modifications of the Mortgage Loans and (iii) the principal portion of
any amount paid on a Balloon Loan, there 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


                                      -13-

     Certificate Principal Balance: As to any Certificate and as of any
Distribution Date, the Initial Certificate Principal Balance of such Certificate

reduction of the Certificate Principal Balance thereof on previous Distribution
Dates pursuant to Section 4.04, and (2) any Applied Realized Loss Amounts
allocated to such Certificate on previous Distribution Dates pursuant to Section

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

(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.

registered in the Certificate Register (initially, Cede & Co., as nominee for

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
the Depositor or any Affiliate of the Depositor in determining which
Certificates are registered in the name of an Affiliate of the Depositor.

                          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

     In connection with such assignment, the Depositor does hereby deliver to,
and deposit with the Trustee the following documents or instruments with respect
to each Mortgage Loan:

     of LaSalle Bank National Association, as trustee for the Merrill Lynch
     First Franklin Mortgage Loan Trust, Mortgage Loan Asset-Backed
     Certificates, Series 2007-4, without recourse" together with all riders
     thereto. The Mortgage Note shall include all intervening endorsements
     showing a complete chain of the title from the originator of the Mortgage
     Loan 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
     original Assignment of each Mortgage in blank or, to "LaSalle Bank National
     Association, as trustee for


                                      -68-

<PAGE>

     the Merrill Lynch First Franklin Mortgage Loan Trust, Mortgage Loan
     Asset-Backed Certificates, Series 2007-4."

          (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 the conveyance
of Mortgage Loans from either Seller to the Depositor is characterized as a
pledge and not a 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 related Seller 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
related Seller 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 FFFC
Purchase Agreement and the MLML Purchase Agreement, including the Depositor's
right, title and interest in the representations and warranties contained in the
FFFC Purchase Agreement and the MLML Purchase Agreement and the benefit of the
repurchase obligations and the obligation of the related Seller contained in the
FFFC Purchase Agreement or the MLML Purchase Agreement, as applicable, 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 FFFC Purchase Agreement and the MLML Purchase
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 Sellers, 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 related Seller 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 Corridor Contracts (forms of
which are attached hereto as Exhibits M-1, M-2 and M-3), the FFFC Purchase
Agreement and the MLML Purchase Agreement.


                                      -70-

     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 Supplemental Interest
Trust Trustee.

     The Trustee agrees, for the benefit of Certificateholders and the NIMs
Insurer 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 NIMs Insurers, 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 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
NIMs Insurer, the Servicer, the related Seller and the Depositor. In addition,
the Trustee shall also notify the NIMs Insurer, the Servicer, the related Seller
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 related Seller 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 related Seller was notified of such
omission or defect and, if the related Seller does not correct or cure such
omission or defect within such period, that the related Seller purchase such
Mortgage Loan from the Issuing Entity within ninety (90) days from the date the
Trustee notified the related Seller 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 related Seller 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
related Seller and necessary to vest in the related Seller 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 related Seller 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 and the NIMs Insurer. The preceding sentence shall not,
however, limit any remedies available to Certificateholders, the NIMs Insurer,
the Depositor or the Trustee pursuant to the FFFC Purchase Agreement or MLML
Purchase Agreement, as applicable.


                                      -71-

     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 Trustee shall keep confidential the name of each Mortgagor
except as required for the performance of this Agreement 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 from
sources other 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 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 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 having a need to know the
same, provided that the Trustee 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 NIMs Insurer, 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 NIMs Insurer,
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, the FFFC
     Purchase Agreement and the MLML Purchase 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, the FFFC Purchase Agreement
     and the MLML Purchase Agreement and has duly authorized, by all necessary
     corporate action on its part, the execution, delivery and performance of
     this Agreement, the FFFC Purchase Agreement and the MLML Purchase
     Agreement; and this Agreement, the FFFC Purchase Agreement and the MLML
     Purchase 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, the FFFC Purchase
     Agreement and the MLML Purchase Agreement by the Depositor, the
     consummation of the transactions contemplated by this Agreement, the FFFC
     Purchase Agreement and the MLML Purchase


                                      -72-

<PAGE>

     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 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, the FFFC Purchase Agreement and the MLML Purchase Agreement or
     the ability of the Depositor to perform its obligations under this
     Agreement, the FFFC Purchase Agreement and the MLML Purchase 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, the FFFC Purchase Agreement and the MLML Purchase 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 Sellers, 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 related Seller with
respect to the Mortgage Loans in the FFFC Purchase Agreement or the MLML
Purchase Agreement, as applicable, which have been assigned to the Trustee
hereunder, were made as of the Closing Date as specified in the FFFC Purchase
Agreement or the MLML Purchase Agreement, as applicable. 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.

          (c) Upon discovery by any of the NIMs Insurer, the Depositor, the
Servicer, the Seller 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 Depositor shall cause the related
Seller to 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. If
a breach of the representations and warranties set forth


                                      -73-

<PAGE>

in the FFFC Purchase Agreement or the MLML Purchase Agreement, as applicable,
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 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 FFFC Purchase Agreement and
the MLML Purchase Agreement, as applicable, if the related Seller substitutes
for a Mortgage Loan for which there is a breach of any representation or
warranty in the FFFC Purchase Agreement or the MLML Purchase Agreement, as
applicable, 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 FFFC Purchase Agreement or the MLML Purchase Agreement, as
applicable, the related Seller 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. The related Seller indemnifies and
holds the Issuing Entity, the Trustee, the Depositor, the Servicer, the NIMs
Insurer 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, the Depositor, the Servicer, the NIMs Insurer and any Certificateholder
may sustain in connection with any actions of the related Seller relating to a
repurchase of a Mortgage Loan other than in compliance with the terms of this
Section 2.03 and the FFFC Purchase Agreement or the MLML Purchase Agreement, as
applicable, 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.

     With respect to any Mortgage Loan repurchased by the related Seller
pursuant to the FFFC Purchase Agreement or the MLML Purchase Agreement, as
applicable, 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 related Seller 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 related Seller, and the Trustee (and its custodian) shall have no further
responsibility with respect to the Mortgage File relating to such Deleted
Mortgage Loan.

     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 related Seller 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


                                      -74-

<PAGE>

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 related Seller, 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 FFFC Purchase
Agreement or the MLML Purchase Agreement, as applicable, including all
applicable representations and warranties thereof included in the FFFC Purchase
Agreement or the MLML Purchase Agreement, as applicable, 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 and (ii) of the related
Seller set forth in the FFFC Purchase Agreement or the MLML Purchase Agreement,
as applicable, 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.

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


                                      -75-
<PAGE>

          (f) The Depositor shall notify the Servicer and the Trustee when any
NIM Notes are issued with the contact information of the issuer thereof and when
such NIM Notes are no longer outstanding and if such NIM Notes are insured by a
NIMs Insurer, the contact information with respect to such NIMs Insurer.

     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 Delaware and is
     duly authorized and qualified to transact any and all business contemplated
     by this Agreement to be conducted by the Servicer in any state in which a
     Mortgaged Property is located or is otherwise not required under applicable

     the doing business laws of any such state, to the extent necessary to
     ensure its ability to enforce each Mortgage Loan, to service the Mortgage
     Loans in accordance with the terms of this Agreement and to perform any of

     hereof.

     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
     which any proceeding therefor may be brought.

          (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,

<PAGE>

          (v) No litigation is pending or, to the best of the Servicer's
     knowledge, threatened, against the Servicer that would materially and

     to perform any of its other obligations under this Agreement in accordance
     with the terms hereof.

          (vi) No consent, approval, authorization or order of any court or

     Servicer has obtained the same.

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

     Upon discovery by the Depositor, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
section 860G(a)(3) of the Code, the party discovering such fact shall promptly
(and in any event within five (5) Business Days of discovery) give written
notice thereof to the other parties. In connection therewith, the Depositor
shall cause the Sponsor, at the Sponsor's option, to either (i) substitute, if
the conditions in Section 2.03(c) with respect to substitutions are satisfied, a
Replacement 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 would a Mortgage Loan for a breach of representation or warranty
contained in Section 2.03. The Trustee, upon the written direction of the
Sponsor, shall reconvey to the Sponsor the Mortgage Loan to be released pursuant
hereto in the same manner, and on the same terms and conditions, as it would a
Mortgage Loan repurchased for breach of a representation or warranty contained

     SECTION 2.06. Authentication and Delivery of Certificates

     The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, the Trustee has caused

entire Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the
rights referred to above for the benefit of all present and future Holders of
the Certificates and to perform its duties set forth in this Agreement in
accordance with the provisions hereof.

     SECTION 2.07. REMIC Elections

          (a) The Depositor hereby instructs and authorizes the Trustee to make
an appropriate election to treat each of the Upper Tier REMIC, the Lower Tier
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


                                      -77-

<PAGE>

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 Corridor Contract and the Corridor Contract Account, (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


                                      -78-

<PAGE>

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 Corridor 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 Corridor Contract Account, the Corridor Contracts, the
Supplemental Interest Trust which holds the Swap Agreement, 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, (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 and (iv) provide, upon applying for and receiving the
tax identification number for the grantor trust from the IRS, a properly
completed Form W-9 on behalf of such grantor trust to the Swap Counterparty and
Cap Contract Counterparty.

          (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


                                      -79-

<PAGE>

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
(other than any Net Swap Payment or Swap Termination Payment made to the Swap
Counterparty) 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 the 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 the 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 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.

     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.


                                      -81-

<PAGE>

     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 NIMs Insurer,
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 NIMs Insurer
and 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 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


                                      -82-

<PAGE>

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

the Corridor Contracts, and to execute and deliver on behalf of the Issuing
Entity, and to perform the duties and obligations of the Issuing Entity under
the Corridor Contracts, an insurance and indemnity agreement with a NIMs Insurer
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. In addition, the Supplemental Interest Trust Trustee is hereby
authorized and directed to execute and deliver, on behalf of the Supplemental
Interest Trust and the Swap Agreement, and to execute and deliver on behalf of
the Issuing Entity, and to perform the duties and obligations of the
Supplemental Interest Trust under any agreement or instrument related to the
Swap Agreement, 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.

     SECTION 2.13. Depositor Notification of NIM Notes

     The Depositor shall notify the Servicer and the Trustee in writing when NIM
Notes are issued and of the identity and contact information of the NIMs
Insurer, if applicable, and when all previously issued NIM Notes are no longer

                                   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
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, including
Section 3.05, 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 in such form as shall
be prepared by the Servicer and agreed to by the Trustee and the Servicer 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


                                      -84-

<PAGE>

attorney to the extent indemnification by the Servicer is required by Section
3.25 and provided that the Servicer shall have no obligation to indemnify the
Trustee for such action to the extent such action was taken pursuant to and in
accordance with specific written instructions from the Trustee, which
instructions are not based on Servicer's recommendations or proposals.
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 Advance or 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.

     In accordance with Accepted Servicing Practices the Servicer will fully
furnish (for the period it services the Mortgage Loans), in accordance with the
Fair Credit Reporting Act and its implementing regulations, accurate and
complete information (e.g., favorable and unfavorable) on its borrower credit
files to Equifax, Experian and Trans Union Credit Information Company on a
monthly basis except as the Servicer deems prudent for prevention or resolution
of disputes with Mortgagors.

     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)).

     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, (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 and the NIMs
Insurer and (iii) the NIMs Insurer shall have consented to such subservicing
agreement, which consent shall not be unreasonably withheld. 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


                                      -85-

<PAGE>

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, with the
consent of the NIMs Insurer (which consent shall not be unreasonably withheld),
in the event a successor servicer is appointed. All actions of the each
subservicer performed pursuant to the 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
and the NIMs Insurer 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 2.05
hereof, (iv) responsible for any


                                      -86-

<PAGE>

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 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 and reasonably acceptable to the NIMs Insurer.

     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 and applicable REMIC
requirements, 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;
provided, further, that the NIMs Insurer's prior written consent shall be
required for any modification, waiver or amendment after the Cut-off Date if the
aggregate number of outstanding Mortgage Loans which have been modified, waived
or amended exceeds 5% of the number of Mortgage Loans as of the Cut-Off Date. 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 clause (ii) above and its related provisos, in the event that
any Mortgage Loan is in default or, in the judgment of the Servicer,


                                      -87-

<PAGE>

such default is reasonably foreseeable, the Servicer, consistent with the
standards set forth in Section 3.01 and not subject to the requirement to make
Advances pursuant to Section 4.01, 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.

     With respect to the Mortgage Loans affected by a hurricane or other natural
disaster, if the Mortgaged Property is located in public and individual
assistance counties, as designated by Federal Emergency Management Agency (as
set forth on its webstie www.fema.gov), the Servicer (or the Subservicer, if
such Servicer is no longer servicing Mortgage Loans), may, at its sole option,
cease collection activities, charging late fees and credit reporting activity
for all Mortgagors in such counties for a period of time and, if reasonably
prudent, may extend such period as long as it deems necessary. In addition, the
Servicer (or the Subservicer, if applicable) may suspend all foreclosure and
bankruptcy activity relating to such Mortgage Loans for a period of time and, if
reasonably prudent, may extend such period as long as it deems necessary.

          (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) 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 (iv) 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 (v) unless the
Depositor has notified the Servicer that there are 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


                                      -88-

<PAGE>

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;

          (v) all Compensating Interest;

          (vi) any amount required to be deposited by the Servicer pursuant to
     Section 3.05(f) 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, all servicing related fees,
including 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, modification fees,
extension fees and other similar ancillary fees and charges (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


                                      -89-

<PAGE>

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 make available to the Trustee 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(f) in connection with any losses on Permitted Investments; and

          (iv) the Optional Termination Amount paid by the Servicer or one of
     its affiliates, or the NIMs Insurer, if any, pursuant to Section 9.01.

     Any amounts received 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


                                      -90-

<PAGE>

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 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, dues or comparable items 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 to withdraw funds
deposited in error or amounts previously deposited but returned as unpaid due to
a "not sufficient funds" or other denial by the related Mortgagor's banking
institution 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.


                                      -91-

<PAGE>

     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 Advancing 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 (which include
Condemnation Proceeds and Insurance 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;

          (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,


                                      -92-

<PAGE>

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 or incorrectly deposited therein or
amounts previously deposited but returned as unpaid due to insufficient funds or
other denial by the related Mortgagor's banking institution; and

          (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.


                                      -93-

<PAGE>

          (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

     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


                                      -94-

<PAGE>

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 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; 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. 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 in accordance with Accepted
Servicing Practices, if in the reasonable judgment of the Servicer not 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


                                      -95-

<PAGE>

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 transfer or assumption which the
Servicer reasonably believes, in accordance with Accepted Servicing Practices,
it is 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 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 and, if applicable, as a Non-Recoverable
Servicing Advance, as contemplated in Section 3.08 hereof.

     With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee, on behalf of the Certificateholders, or its
nominee (which nominee shall not be the Servicer). 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.


                                      -96-

<PAGE>

     In the event that the Issuing Entity acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or reasonably foreseeable
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 and the NIMs Insurer shall have
been supplied with an Opinion of Counsel addressed to the Trustee (such Opinion
of Counsel not to be an expense of the Trustee or the NIMs Insurer), 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 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.

     Notwithstanding the foregoing provisions of this Section 3.12 or any other
provision of this Agreement, with respect to any Mortgage Loan as to which the
assistant vice president for foreclosures or the vice president of default
management of the Servicer has actual knowledge (which shall not be presumed due
to any documents received by the Servicer) of, the presence of any toxic or
hazardous substance on the related Mortgaged Property, the Servicer shall not,
on behalf of the Trustee, either (i) obtain title to such Mortgaged Property as
a result of or in lieu of foreclosure or otherwise, or (ii)


                                      -97-

<PAGE>

otherwise acquire possession of, or take any other action with respect to, such
Mortgaged Property, if, as a result of any such action, the Trustee, the Issuing
Entity or the Certificateholders would be considered to hold title to, to be a
"mortgagee-in-possession" of, or to be an "owner" or "operator" of such
Mortgaged Property within the meaning of the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended from time to time,
or any comparable law, unless the Servicer believes, based on its reasonable
judgment and a report prepared by a Person who regularly conducts environmental
audits using customary industry standards, that:

     (1) such Mortgaged Property is in material compliance with applicable
environmental laws or, if not, that it would be in the best economic interest of
the Issuing Entity to take such actions as are necessary to bring the Mortgaged
Property into compliance therewith; and

     (2) it is probable that there are no circumstances present at such
Mortgaged Property relating to the use, management or disposal of any hazardous
substances, hazardous materials, hazardous wastes, or petroleum-based materials
for which additional investigation, testing, monitoring, containment, clean-up
or remediation could be required under any federal, state or local law or
regulation, or that if any such materials are present for which such action
could be required, that it would be in the best economic interest of the Issuing
Entity to take such actions with respect to the affected Mortgaged Property.

     The Servicer shall forward a copy of the environmental audit report to the
Depositor and the Trustee. The cost of the environmental audit report
contemplated by this Section 3.12 shall be advanced by the Servicer, subject to
the Servicer's right to be reimbursed therefor from the Collection Account, such
right of reimbursement being prior to the rights of Certificateholders to
receive any amount in the Collection Account received in respect of the affected
Mortgage Loan or other Mortgage Loans.

     If the Servicer determines, as described above, that it is in the best
economic interest of the Issuing Entity to take such actions as are necessary to
bring any such Mortgaged Property into compliance with applicable environmental
laws, or to take such action with respect to the containment, clean-up or
remediation of hazardous substances, hazardous materials, hazardous wastes or
petroleum-based materials affecting any such Mortgaged Property, then the
Servicer may take such action as it deems to be in the best economic interest of
the Issuing Entity; provided that any amounts disbursed by the Servicer pursuant
to this Section 3.12 shall constitute Advances. The cost of any such compliance,
containment, clean-up or remediation shall be advanced by the Servicer, subject
to the Servicer's right to be reimbursed therefor from the Collection Account,
such right of reimbursement being prior to the rights of Certificateholders to
receive any amount in the Collection Account received in respect of the affected
Mortgage Loan or other Mortgage Loans. If the Servicer decides not to take such
action, it may not obtain title to such Mortgaged Property.

     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


                                      -98-

<PAGE>

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.

          (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 may
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 that 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


                                      -99-

<PAGE>

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 a
servicing fee, (ii) the servicing thereof and the servicing fee shall be
pursuant to a servicing agreement between the Depositor and the Servicer if the
Servicer continues to service such loan, (iii) the majority holder of the Class
C Certificates may designate any servicer to service any such released loan and
(iv) the majority holder of the Class C Certificates may sell any such released
loan to a third party.

     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 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


                                     -100-

<PAGE>

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 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.

     The Servicer shall not have any liability for and shall be excused from the
performance of the Agreement to the extent the Servicer is unable to perform due
to the Trustee's or the Custodian's failure to release the related Mortgage File
or the Trustee's or the Custodian's failure to execute and release documents in
a timely manner.


                                     -101-

<PAGE>

     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
or recovery 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), bad check charges,
modification fees and similar fees and charges 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

     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


                                     -102-

<PAGE>

provided in this Section as a result of such obligation shall not constitute a
breach of this Section. The Servicer shall provide to the Trustee access to its
records regarding the Mortgage Loans upon reasonable prior notice and during
regular business hours.

     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 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, 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 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 be provided to the Trustee and the
Depositor that attests to and reports on the Assessment of Compliance provided

          (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 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


                                     -105-

<PAGE>

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
reasonably foreseeable 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 (or other word processing format that is acceptable to
the Trustee) agreed upon by the Trustee and Depositor, Sponsor 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 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, unless the Servicer has
received from the Depositor a notice to the contrary, a duly authorized
representative of the Servicer shall sign the Form 8-K and return an


                                     -106-

<PAGE>

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 a Microsoft Word format (or other
word processing format that is acceptable to the Trustee) (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) 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


                                     -107-

<PAGE>

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, 2008 (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 2008, (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 Microsoft Word format (or such
other word processing format that is acceptable to the Trustee), 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 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


                                     -108-

<PAGE>

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 12B25 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.

     On or before January 30, 2008, the Trustee shall, if legally permissible
under applicable regulations and interpretations of the Commission, 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 in a
Microsoft Word format (or other word processing format that is acceptable to the
Trustee) 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.

     The Trustee shall not have any responsibility to file any items (other than
those generated by it) that have not been received in a format suitable (or
readily convertible into a format suitable) for electronic filing via the EDGAR
system and shall not have any responsibility to convert any such items to such
format (other than those items generated by it or that are readily convertible
to such format).

     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


                                     -109-

<PAGE>

Exchange Act. Notwithstanding the foregoing, the Depositor, the Servicer, and
the Trustee shall not be 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


                                     -110-

<PAGE>

Sections 3.18(g) and 3.18(h) in connection with the Servicer's document
preparation under Sections 3.17, 3.18 and 3.20, and the Servicer shall be
entitled to rely conclusively upon and shall have no liability for any errors in
such information.

     SECTION 3.23. Prepayment Charge Reporting Requirements

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

          (ii) current Mortgage Rate;

          (iii) current principal balance;

          (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 4.04(j) and (ii) a
delinquency report in the form attached hereto as Exhibit V 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 information arising from the
related Prepayment Period, and (b) furnish to the Trustee, by 3:00 P.M., EST on
the next succeeding Business Day after the 18th day, a cumulative version of the
aforementioned reports which includes such information arising from the related
Prepayment Period.

     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


                                     -111-

<PAGE>

Agreement or the Mortgage Loans and, if subject to this indemnification
obligation, assume (with the 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. Solicitation

     The Servicer may solicit or refer to a mortgage originator, who may or may
not be an affiliate of the Depositor or the Servicer, any Mortgagor for
refinancing or otherwise take action to encourage refinancing.

     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 Sponsor will
repurchase the Mortgage Loan within a 30 day period from the date of the notice
in the manner described in Section 2.05.

     SECTION 3.28. Rights of the NIMs Insurer

     Each of the rights of the NIMs Insurer set forth in this agreement shall
exist so long as NIM Notes have been issued pursuant to the Indenture remain
outstanding that are insured by a NIMs Insurer or the NIMs Insurer is owed
amounts in respect of its guarantee of payment on such NIM notes.

                                   ARTICLE IV

                                  DISTRIBUTIONS

     SECTION 4.01. Advances

          (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


                                     -112-

<PAGE>

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 NIMs Insurer 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 Trustee. In addition, the Servicer shall not be
required to advance any Relief Act Shortfalls, shortfalls due to bankruptcy
proceedings and shortfalls due to modifications as provided in Section 3.05.

          (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


                                     -113-

<PAGE>

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; provided that the amount so deposited shall
not exceed the Compensating Interest for such Distribution Date. 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 or bankruptcy proceedings and the Servicer shall not
be obligated to pay Compensating Interest with respect to Prepayment Interest
Shortfalls related to the Relief Act or bankruptcy proceedings.

     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 or the Sponsor in respect of Prepayment Charges pursuant to this
Agreement, 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 FFFC Purchase Agreement or the
MLML Purchase Agreement, as applicable, for the related Prepayment Period;

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

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 1-A, Class 2-A and Class R
Certificates in the aggregate;

pro rata among each class of the Class M1 Certificates based upon the ratio of
(x) the Current Interest and Interest Carry Forward Amount for each such class
to (y) the total amount of Current Interest and any Interest Carry Forward
Amount for the Class M1 Certificates in the aggregate;

          (vi) concurrently, to each class of the Class M2 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

Forward Amount to the Class M2 Certificates, Interest Funds will be distributed
pro rata among each class of the Class M2 Certificates based upon the ratio of
(x) the Current Interest and Interest Carry Forward Amount for each such class
to (y) the total amount of Current Interest and any Interest Carry Forward
Amount for the Class M2 Certificates in the aggregate;

          (vii) concurrently, to each class of the Class M3 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 M3 Certificates, Interest Funds will be distributed
pro rata among each class of the Class M3 Certificates based upon the ratio of
(x) the Current Interest and Interest Carry Forward Amount for each such class
to (y) the total amount of Current Interest and any Interest Carry Forward
Amount for the Class M3 Certificates in the aggregate;

          (viii) to the Class M4 Certificates, the Current Interest for such
class and any Interest Carry Forward Amount with respect to such Class;

<PAGE>

          (xii) to the Class B2 Certificates, the Current Interest for each such
class and any Interest Carry Forward Amount with respect to each such Class;

     On each Distribution Date, subject to the provisos in (iv) - (vii) above,
Interest Funds received on the Group One Mortgage Loans will be deemed to be
distributed to the Group One Certificates and Interest Funds received on the
Group Two Mortgage Loans will be deemed to be distributed to the Group Two

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,

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

     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
Corridor Contracts on behalf of the Issuing Entity in the form presented to it
by the Depositor and shall have no responsibility for the contents of such
Corridor Contracts, including, without limitation, the representations and
warranties contained therein. Any funds payable by the Issuing Entity under the
Corridor Contracts at closing shall be paid by the Depositor. Any payments
received under the terms of the related Corridor Contract will be available to
pay the holders of the related Certificate Group One, Certificate Group Two, or
the Class M4, Class M5, Class M6 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 Corridor 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 Corridor Contract
shall be paid to the related classes of Certificate Group One, Certificate Group
Two, and the Class M4, Class M5, Class M6 and Class B Certificates, pro rata
based upon such Floating Rate Certificate Carryovers for each such class of
Certificate Group One, Certificate Group Two, and the Class M4, Class M5, Class
M6 and Class B Certificates. Amounts received on the Group One Corridor Contract
will only be available to make payments on Certificate Group One, amounts
received on the Group Two Corridor Contract will only be available to make
payments on Certificate Group Two, amounts received on the Class M4, Class M5,
Class M6 and Class B Corridor Contract will only be available to make payments
on the Class M4, Class M5, Class M6 and Class B Certificates.

          (i) The Trustee shall establish and maintain, for the benefit of the
Issuing Entity and the Certificateholders, the Corridor Contract Account. On or
prior to the related Corridor Contract Termination Date, amounts, if any,
received by the Trustee for the benefit of the Issuing Entity in respect of the
related Corridor Contract shall be deposited by the Trustee into the Corridor
Contract Account and will be used to pay Floating Rate Certificate Carryovers on
the related Certificate Group One, Certificate Group Two and the Class M4, Class
M5, Class M6 and Class B Certificates to the extent provided in the immediately
preceding paragraph. With respect to any Distribution Date on or prior to the
related Corridor Contract Termination Date, the amount, if any, payable by the
Cap Contract Counterparty under the related Corridor Contract will equal the
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 Corridor 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 Corridor Contract, (ii) an amount equal to the
lesser of (x) the related Corridor 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 Issuing Entity under a
Corridor 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(b) hereof.


                                      -121-

<PAGE>

          (ii) Amounts on deposit in the Corridor Contract Account will remain
uninvested pending distribution to Certificateholders.

          (iii) Each Corridor Contract is scheduled to remain in effect until
the related Corridor 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
Corridor Contract, after notice of such failure is received by the Cap Contract
Counterparty) to make a payment due under the related Corridor 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 Corridor Contract, the termination of the Trust
Fund and the related Corridor Contract becoming illegal or subject to certain
kinds of taxation.

          (iv) On the Closing Date, the Cap Contract Counterparty and the
Trustee (which is hereby authorized and directed to enter into such credit
support annex) will enter into a credit support annex in relation to the
Corridor Contracts, which annex is intended to protect the Issuing Entity from
certain ratings downgrades that might hinder the ability of the Cap Contract
Counterparty to continue its obligations under the Corridor Contracts.

     Pursuant to and in accordance with the terms and provisions of the Corridor
Contracts, the Cap Contract Counterparty may be required to post additional
collateral in connection with its obligations under the Corridor Contracts. In
connection with the foregoing, the Trustee shall establish a Corridor Posted
Collateral Account on the Closing Date.

     To the extent that the Cap Contract Counterparty remits any Posted
Collateral to the Trustee under the Corridor Contracts, the Trustee shall, upon
receipt of the Posted Collateral, deposit the Posted Collateral into the
Corridor Posted Collateral Account and shall hold, release and disburse such
collateral in accordance with the terms and provisions of the Corridor
Contracts. Where a termination event occurs with respect to the Cap Contract
Counterparty under the Corridor Contracts, or where the Cap Contract
Counterparty fulfills certain obligations to the Issuing Entity such as finding
a replacement cap contract counterparty or a guarantor that meets the criteria
described in the Corridor Contracts, the Trustee shall make payments from the
Corridor Posted Collateral Account in accordance with the provisions of the
Corridor Contract. Amounts held in the Corridor Posted Collateral Account will
not be part of the Trust Fund and will not be available for distribution to any
Certificateholders, except to the extent distributed to the Corridor Contract
Account pursuant to the Corridor Contracts. Any funds held in the Corridor
Posted Collateral Account shall be invested by the Trustee in Eligible
Investments in accordance with the instructions of the Cap Contract
Counterparty. Any earnings shall be remitted to the Cap Contract Counterparty in
accordance with the Corridor Contracts. The Trustee shall not be responsible for
any losses. Absent receipt by the Trustee of written instructions from the Cap
Contract Counterparty, such funds shall remain uninvested.

          (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 Supplemental Interest Trust 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 or the Supplemental Interest Trust Trustee held pursuant to this
Agreement. In no event shall any funds deposited in the Supplemental


                                      -122-

<PAGE>

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 Supplemental Interest Trust Trustee is hereby directed by the Depositor
to execute the Swap Agreement on behalf of the Supplemental Interest Trust in
the forms presented to it by the Depositor and shall have no responsibility for
the contents of such Swap Agreement, including, without limitation, the
representations and warranties contained therein. The Supplemental Interest
Trust Trustee shall have all of the rights and protections of the Trustee
hereunder. The Depositor is hereby directed to make, or cause to be made, the
"additional payment" (as described in the Swap Agreement) on behalf of the
Supplemental Interest Trust.

     The Supplemental Interest Trust 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
June 2012, the Supplemental Interest Trust 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 each of the Swap Agreement. If on any such
Distribution Date, the Significance Percentage is equal to or greater than 9%,
the Supplemental Interest Trust Trustee shall promptly notify the Depositor and
the Depositor, on behalf of the Supplemental Interest Trust 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 Date in June 2012, the
Significance Percentage is equal to or greater than 10%, the Supplemental
Interest Trust Trustee shall promptly notify the Depositor and the Depositor
shall, within five (5) Business Days of such Distribution Date, deliver to the
Supplemental Interest Trust Trustee the financial information provided to it by
the Swap Counterparty in Microsoft Word format (or other word processing format
that is acceptable to the Supplemental Interest Trust Trustee) for inclusion in
the Form 10-D relating to such Distribution Date.

     Any Swap Termination Payment received by the Supplemental Interest Trust
Trustee shall be deposited in the Swap Account 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
Supplemental Interest Trust Trustee of the Swap Termination Payment paid by the
terminated Swap Counterparty, the Supplemental Interest Trust Trustee shall
deposit such Swap Termination Payment into a separate, segregated non-interest
bearing subtrust established by the Supplemental Interest Trust Trustee and the
Supplemental Interest Trust 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(l)(i)-(viii) of this Agreement. Any such subtrust
shall not be an asset of any REMIC. Any amounts remaining in such


                                      -123-

<PAGE>

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) June 25, 2012.

     On any Distribution Date (or in the case of any Net Swap Payments, on the
related Swap Payment Date), any Swap Termination Payments or Net Swap Payments
owed to the Swap Counterparty will be paid out of and any Net Swap Payments or
Swap Termination Payments received from the Swap Counterparty will be deposited
into the Swap Account (an account within the Supplemental Interest Trust). The
Supplemental Interest Trust will not be an asset of any REMIC. Funds in the Swap
Account within the Supplemental Interest Trust 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;

          (iv) sequentially, to the Class M1 Certificates, the Class M2
Certificates, the Class M3 Certificates, the Class M4 Certificates, the Class M5
Certificates, the Class M6 Certificates, the Class B1 Certificates, the Class B2
Certificates and the Class B3 Certificates, in that order, any Current Interest
for such class to the extent unpaid; provided, however that any amounts
distributed to the Class M1, Class M2 and Class M3 Certificates shall be
distributed to each class of such Class M Certificates, pro rata, based on
Current Interest due to each class;

          (v) sequentially, to the Class M1 Certificates, the Class M2
Certificates, the Class M3 Certificates, the Class M4 Certificates, the Class M5
Certificates, the Class M6 Certificates, the Class B1 Certificates, the Class B2
Certificates and the Class B3 Certificates, in that order, any Interest Carry
Forward with respect to such class to the extent unpaid; provided, however that
any amounts distributed to the Class M1, Class M2 and Class M3 Certificates
shall be distributed to each class of such Class M Certificates, pro rata, based
on Interest Carry Forward Amount due to each class;

          (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)(xii) 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 M1 Certificates, the Class M2
Certificates, the Class M3 Certificates, the Class M4 Certificates, the Class M5
Certificates, the Class M6 Certificates, the Class B1 Certificates, the Class B2
Certificates and the Class B3 Certificates, in that order, any Unpaid Realized
Loss Amount for such class to the extent unpaid; provided, however that any
amounts distributed to the Class M1, Class M2 and Class M3 Certificates shall be
distributed to each class of such Class M Certificates, pro rata, based on any
Unpaid Realized Loss Amount due to each class;


                                      -124-

<PAGE>

          (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 Swap
Account within 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 Supplemental Interest Trust Trustee
shall send any notices and make any demands required hereunder (to the extent
that a Responsible Officer of the Trustee has actual knowledge or written notice
of any such failure, breach or termination).

     On the Closing Date, the Swap Counterparty and the Supplemental Interest
Trust Trustee (which is hereby authorized and directed to enter into such credit
support annex) will enter into a credit support annex in relation to the Swap
Agreement, which annex is intended to protect the Supplemental Interest Trust
from certain ratings downgrades that might hinder the ability of the Swap
Counterparty to continue its obligations under the Swap Agreement.

     Pursuant to and in accordance with the terms and provisions of the Swap
Agreement, the Swap Counterparty may be required to post additional collateral
in connection with its obligations under the Swap Agreement. In connection with
the foregoing, on the Closing Date, the Supplemental Interest Trust Trustee
shall establish and maintain a Swap Posted Collateral Account.

     To the extent that the Swap Counterparty remits any Posted Collateral to
the Supplemental Interest Trust Trustee under the Swap Agreement, the
Supplemental Interest Trust Trustee shall, upon receipt of the Posted
Collateral, deposit the Posted Collateral into the Swap Posted Collateral
Account and shall hold, release and disburse such collateral in accordance with
the terms and provisions of the Swap Agreement. Where a termination event occurs
with respect to the Swap Counterparty under the Swap Agreement, or where the
Swap Counterparty fulfills certain obligations to the Supplemental Interest
Trust such as finding a replacement swap counterparty or a guarantor that meets
established criteria of the Rating Agencies, the Supplemental Interest Trust
Trustee shall make payments from the Swap Posted Collateral Account in
accordance with the provisions of the Swap Agreement. Amounts held in the Swap
Posted Collateral Account will not be part of the Trust Fund and will not be
available for distribution to any Certificateholders, except to the extent
distributed to the Swap Account pursuant to the Swap Agreement. Any funds held
in the Swap Posted Collateral Account shall be invested by the Trustee in


                                      -125-

<PAGE>

Eligible Investments in accordance with the instructions of the Swap
Counterparty. Any earnings shall be remitted to the Swap Counterparty in
accordance with the Swap Agreement. The Trustee shall not be responsible for any
losses. Absent receipt by the Trustee of written instructions from the Swap
Counterparty, such funds shall remain uninvested.

(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 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


                                      -131-

<PAGE>

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
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 whether or not such notes are guaranteed by the NIMs Insurer)
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,


                                      -132-

<PAGE>

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.

     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 will not constitute or result in
a non-exempt prohibited transaction under Title I of ERISA or Section 4975 of
the Code.

     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 and the NIMs
Insurer 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, the
NIMs Insurer 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, the NIMs Insurer 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).


                                      -133-

<PAGE>

     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 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.


                                      -134-

<PAGE>

          (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 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.


                                      -135-

<PAGE>

          (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 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 NIMs Insurer, the Trustee and any agent of the NIMs Insurer or 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 neither the NIMs
Insurer nor the Trustee, nor any agent of the NIMs Insurer or 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 NIMs Insurer or 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
NIMs Insurer or 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


                                      -136-

<PAGE>

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

          (b) the Depositor, the NIMs Insurer 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, 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


                                      -137-

<PAGE>

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

     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 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 and the NIMs Insurer 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, Suite 1511, Chicago, Illinois 60603,
Attention: FFMER 2007-4 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


                                      -138-

<PAGE>

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


                                      -139-

<PAGE>

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

     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 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 and the


                                      -140-

<PAGE>

NIMs Insurer. No such resignation shall become effective until the Trustee or a
successor servicer reasonably acceptable to the Trustee and the NIMs Insurer 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 and the NIMs Insurer 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 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.

events:


                                      -141-
<PAGE>

          (i) any failure by the Servicer to make any Advance, to deposit in the
Collection Account or the Certificate Account or remit to the Trustee any
payment (excluding a payment required to be made under Section 4.01 hereof)
required to be made under the terms of this Agreement, which failure shall
continue unremedied for three Business Days and, 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 NIMs Insurer or the Holders of Certificates evidencing
greater than 50% of the Voting Rights evidenced by the Certificates; or

          (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 3.20 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, described in (i) - (v) above, 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 NIMs Insurer or the Holders
of Certificates evidencing greater than 50% of the Voting Rights evidenced by
the Certificates (with the written consent of the NIMs Insurer (such consent
shall not be unreasonably withheld), except after a NIMs Insurer Default),
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. If an Event of Default, described
in (vi) above, 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, at the direction of the
Depositor or at the direction of the Holders of Certificates


                                      -142-

<PAGE>

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 Mortgage Loans. The Servicer and the Trustee shall promptly
notify the Rating Agencies, the Cap Contract Counterparty and the Swap
Counterparty 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 Section 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 acceptable to the NIMs Insurer and is a Fannie Mae and Freddie Mac approved
seller/servicer in good standing, that has a net worth of at


                                      -143-

<PAGE>

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, prior written consent of the NIMs Insurer is obtained
(provided, that such prior written consent shall not be required in the event
that the Servicing Rights Pledgee or its designee is so appointed as successor
servicer) 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
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, to each Rating Agency, the Cap Counterparty
and the Swap Counterparty.

          (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

     For purposes of this Article VIII, references to "Trustee" shall be deemed
to include LaSalle Bank National Association, in its capacity as Supplemental
Interest Trust Trustee under this Agreement


                                      -144-

<PAGE>

and the Swap Agreement, and in respect thereof, the Supplemental Interest Trust
Trustee shall have all of the rights, protections, immunities and benefits 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 the
NIMs Insurer, or may, proceed to protect and enforce its rights and the rights
of the Certificateholders or the NIMs Insurer 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, the NIMs Insurer 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 the NIMs
Insurer and take such further action as directed by the Certificateholders and
the NIMs Insurer.

     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;

          (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


                                      -145-

NIMs Insurer or 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; and

          (iv) the Trustee shall not be responsible for the acts or omissions of
any Servicer or any Subservicer, it being understood that this Agreement shall
not be construed to render any of them agents of one another.

     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

request, consent, order, approval, bond or other paper or document, unless
requested in writing so to do by the NIMs Insurer or 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

with due care by it hereunder;

          (vi) the Trustee shall not be required to expend its own funds or

any loss on any investment of funds pursuant to this Agreement or the Swap

                                      -146-

<PAGE>

          (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

matters arising hereunder or to institute, conduct or defend any litigation

costs, expenses and liabilities that may be incurred therein or thereby;

          (x) if requested by the Servicer, the Trustee shall 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,

          (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

trial or other proceeding relating thereto, and any such suit, action or

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 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

     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


                                      -147-

<PAGE>

     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;

          (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.


                                      -148-

<PAGE>

          (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 there is a NIMs Insurer and shall cease to apply
after the date on which any NIM Notes are paid in full or if there is no NIMs
Insurer; 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 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, the NIMs
Insurer and their 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


                                      -149-

<PAGE>

acceptable to the NIMs Insurer 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 the NIMs Insurer 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, with the consent of the NIMs Insurer, 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 (or by the NIMs Insurer), 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 the NIMs
Insurer and 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, the NIMs Insurer, the Servicer, the Cap Contract Counterparty and the
Swap Counterparty 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 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


                                      -150-

<PAGE>

     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 and the NIMs Insurer 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 and the NIMs Insurer. 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 and the NIMs Insurer 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:

          (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, with the consent of the NIMs Insurer, may at any
time accept the resignation of or remove any separate trustee or co-trustee.


                                      -151-

<PAGE>

     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
NIMs Insurer and 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 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,


                                      -152-

<PAGE>

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 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


                                      -153-

<PAGE>

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 Corridor 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 Corridor 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 B3 Certificates (pro rata), third
to the Class B2 Certificates (pro rata), fourth to the Class B1 Certificates
(pro rata), fifth to the Class M6 Certificates (pro rata), sixth to the Class M5
Certificates (pro rata), seventh to the Class M4 Certificates (pro rata), eighth
to the Class M3 Certificates (pro rata), ninth to the Class M2 Certificates (pro
rata), tenth to the Class M1 Certificates (pro rata) and eleventh 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

     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 any Distribution Date following the Initial Optional
Termination Date, the Servicer may, 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. Upon the exercise of such option by the Servicer,
the Trustee shall immediately notify the Swap Counterparty that an Optional
Termination has occurred and that final distributions on the Certificates will
be made on the immediately following Distribution Date. Upon such notice, the
Swap Counterparty shall inform the Trustee of the final Swap


                                      -154-

<PAGE>

Termination Payment amount owed to the Swap Counterparty. In connection with any
such optional 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 Servicer (or an Affiliate of the
Servicer) shall be deposited by the Trustee directly into the Certificate
Account immediately upon receipt. 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 the Servicer does not exercise its right under this Section 9.01(b) to
purchase all of the Mortgage Loans, the NIMs Insurer may, at its option,
terminate the Trust Fund on any Distribution Date by purchasing all of the
Mortgage Loans and REO Properties at the 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
Servicer (or an Affiliate of the Servicer) shall be deposited by the Trustee
directly into the Certificate Account immediately upon receipt.

          (c) [Reserved].

     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


                                      -155-

<PAGE>

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 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


                                      -156-

<PAGE>

          (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.

          (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 Fund 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.

                            MISCELLANEOUS PROVISIONS

     SECTION 10.01. Amendment

     This Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the NIMs Insurer (such consent
shall not be unreasonably withheld) and without the consent of any of the
Certificateholders,


                                      -157-

<PAGE>

          (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 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 (referenced in
(iv) above) 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 and the NIMs Insurer 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
or the NIMs Insurer, 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, with the consent
of the NIMs Insurer, 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. A copy of such Opinion of
Counsel shall be provided to the NIMs Insurer.


                                      -158-

<PAGE>

     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 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 Cap Contract Counterparty or the Swap
Counterparty without first obtaining the consent of the Cap Contract
Counterparty or Swap Counterparty, respectively.

     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


                                      -159-

<PAGE>

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.

     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 the NIMs Insurer, the Rating Agency, the Cap Contract Counterparty and the
Swap Counterparty 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:


                                      -160-

<PAGE>

and

          (iii) Each annual independent public accountants' servicing report

in the Swap Agreement and the Corridor Contracts, and in the case of any of the
foregoing persons, such other addresses as may hereafter be furnished by any
such persons to the other parties to this Agreement. Notices to
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; Sales; Advance Facilities

     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


                                      -161-

<PAGE>

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 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 the Swap Counterparty 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

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 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 and/or the NIMs Insurer, or to obtain or seek to obtain
priority over or preference to any other such Holder and/or the NIMs Insurer 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
is necessary to comply with the provisions of Regulation AB.

     SECTION 10.12. Third Party Rights

     The Cap Contract Counterparty and the Swap Counterparty shall be deemed
third party beneficiaries of this Agreement regarding provisions related to
payments owed to the Cap Contract Counterparty or Swap Counterparty,
respectively, so long as any of the Corridor Contracts or the Swap Agreement, as
applicable, remains in effect.

     The NIMs Insurer, if any, shall also be deemed to be a third party
beneficiary of this Agreement as long as NIM Notes are issued and outstanding.

     SECTION 10.13. Additional Rights of the NIMs Insurer

     Provided that a party to this Agreement has been provided with the contact
information of the NIMs Insurer, such party, any agent thereof and any successor
thereto shall furnish to the NIMs Insurer a copy of any notice, direction,
demand, opinion, schedule, list, certificate, report or filing required to be
provided under this Agreement and provided by it or on its behalf to any other
Person pursuant to this Agreement at the same time, in the same form and in the
same manner as such communication is so provided and shall address or cause such
communication to be addressed to the NIMs Insurer in addition to any other
addressee thereof. The Servicer shall cause the NIMs Insurer to be an addressee
of any report furnished pursuant to this Agreement. With respect to the Trustee,
such obligation shall be satisfied with the provision of access to the NIMs
Insurer to the Trustee's website.

     Unless there exists a continuance of any failure by the NIMs Insurer to
make a required payment under the policy insuring the NIM Notes (such event, a
"NIMs Insurer Default"), wherever in this Agreement there shall be a requirement
that any Person or any communication, object or other matter be acceptable or
satisfactory to or otherwise receive the consent or other approval of any other
Person (whether as a condition to the eligibility of such Person to act in any
capacity, as a condition to any circumstance or state of affairs related to such
matter, or otherwise), there also shall be deemed to be a requirement that such
Person or matter be approved in writing by the NIMs Insurer, which approval
shall not be unreasonably withheld or delayed.

                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

evidencing an ownership interest in distributions allocable to the Class
[_]-[A[_]][M[_]] Certificates with respect to a pool of conventional, sub-prime
mortgage loans formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

          Unless this Certificate is presented by an authorized representative
     of The Depository Trust Company, a New York corporation ("DTC"), to the
     Trustee for registration of transfer, exchange or payment, and any
     certificate issued is registered in the name of Cede & Co. or in such other
     name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
     FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
     registered owner hereof, Cede & Co. has an interest herein.

          This certifies that CEDE & CO. is the registered owner of the
     ownership interest (the "Ownership Interest") evidenced by this Certificate
     (obtained by dividing the Original Denomination of this Certificate by the
     aggregate Initial Certificate Balance of all Class A-1 Certificates) in
     certain distributions with respect to a pool of conventional, sub-prime
     mortgage loans (the "Mortgage Loans") formed and sold by Merrill Lynch
     Mortgage Investors, Inc. (hereinafter called the "Depositor"), and certain
     other property held in trust for the benefit of Certificateholders
     (collectively, the "Trust Fund"). The Mortgage Loans are serviced by Home
     Loan Services, Inc. (the "Servicer") and are secured by first-lien
     mortgages on the Mortgaged Properties. The Trust Fund was created pursuant
     to a pooling and servicing agreement (the "Agreement"), dated as of June 1,
     2007, among the Depositor, the Servicer and LaSalle Bank National
     Association ("LB"), as trustee (the "Trustee"), a summary of certain of the
     pertinent provisions of which is set forth hereafter. To the extent not
     defined herein, the capitalized terms used herein have the meanings
     assigned in the Agreement.

          This Certificate is one of a duly authorized issue of Certificates,
     designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series
     2007-4 Mortgage Loan Asset-Backed Certificates, Class [_]-[A[_]][M[_]] (the
     "Class [_]-[A[_]][M[_]] Certificates") and is issued under and is subject
     to the terms, provisions and conditions of the Agreement, to which
     Agreement the Holder of this Certificate by virtue of the acceptance hereof
     assents and by which Agreement such Holder is bound.

          The Class A Certificates, the Class M Certificates, the Class B
     Certificates, the Class P Certificates and the Class C Certificates are
     collectively referred to herein as the "Certificates."

          Pursuant to the terms of the Agreement, the Trustee will distribute
     from funds in the Certificate Account the amounts described in the
     Agreement on the 25th day of each month or, if such 25th day is not a
     Business Day, the Business Day immediately following (the "Distribution
     Date"), commencing in July 2007. Such distributions will be made to the
     Person in whose name this Certificate is registered on the Recorded Date
     (as such term is defined in the Agreement).


                                       A-4

<PAGE>

     Distributions on this Certificate will be made either by wire transfer in
immediately available funds to the account of such certificateholder at a bank
or other depository institution having appropriate wire transfer facilities or,
in the case of any certificateholder that has so notified the Trustee in writing
in accordance with the Agreement, by check mailed to the address of the person
entitled to distributions as it appears on the Certificate Register; provided,
however, that the final distribution in retirement of the certificates will be
made only upon presentation and surrender of this Certificate at the office of
the Trustee or such other address designated in writing by the Trustee. On each
Distribution Date, a holder of this Certificate will receive such holder's
Percentage Interest of the amounts required to be distributed with respect to
the applicable Class of Certificates.

          The Trustee will maintain or cause to be maintained a Certificate
     Register in which, subject to such reasonable regulations as it may
     prescribe, the Trustee will provide for the registration of Certificates
     and of transfers and exchanges of Certificates. Upon surrender for
     registration of transfer of any Certificate at any office or agency of the
     Trustee, or, if an Authenticating Agent has been appointed under the
     Agreement, the Authenticating Agent, maintained for such purpose, the
     Trustee, will, subject to the limitations set forth in the Agreement,
     authenticate and deliver, in the name of the designated transferee or
     transferees, a Certificate of a like class and dated the date of
     authentication by the Authenticating Agent. Notwithstanding the above, the
     final distribution on this Certificate will be made after due notice by the
     Trustee, of the pendency of such distribution and only upon presentation
     and surrender of this Certificate at the office or agency appointed by the
     Trustee, for that purpose and specified in such notice of final
     distribution.

          Reference is hereby made to the further provisions of this Certificate
     set forth on the reverse hereof which further provisions shall for all
     purposes have the same effect as if set forth at this place.

          Unless the certificate of authentication has been executed by the
     Authenticating Agent, by manual signature, this Certificate shall not be
     entitled to any benefit under the Agreement or be valid for any purpose.

          IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly

                             REVERSE OF CERTIFICATE

         MERRILL LYNCH FIRST FRANKLIN MORTGAGE LOAN TRUST, SERIES 2007-4
                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

          This Certificate is one of a duly authorized issue of Certificates,
     designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series
     2007-4 Mortgage Loan Asset-Backed Certificates, issued in one or more
     Classes of Class A Certificates, Class M Certificates, Class B
     Certificates, Class P Certificates and Class C Certificates, each
     evidencing an interest in certain distributions with respect to a pool of
     conventional, sub-prime Mortgage Loans formed and sold by the Depositor and
     certain other property conveyed by the Depositor to the Trustee.

          Following the initial issuance of the Certificates, the principal
     balance of this Certificate will be different from the Original
     Denomination shown above. Anyone acquiring this Certificate may ascertain
     its current principal balance by inquiry of the Trustee.

          The Holder, by its acceptance of this Certificate, agrees that it will
     look solely to the Trust Fund and certain amounts resulting from credit
     enhancements for payment hereunder and that the Trustee is not liable to
     the Holders for any amount payable under this Certificate or the Agreement
     or, except as expressly provided in the Agreement, subject to any liability
     under the Agreement.

          This Certificate does not purport to summarize the Agreement and
     reference is made to the Agreement for the interests, rights and
     limitations of rights, benefits, obligations and duties evidenced hereby,
     and the rights, duties and immunities of the Trustee.

          No service charge will be made to the Holder for any transfer or
     exchange of the Certificate, but the Trustee may require payment of a sum
     sufficient to cover any tax or governmental charge that may be imposed in
     connection with any transfer or exchange of the Certificate. Prior to due
     presentation of a Certificate for registration of transfer, the Depositor
     and the Trustee may treat the person in whose name any Certificate is
     registered as the owner of such Certificate and the Percentage Interest in
     the Trust Fund evidenced thereby for the purpose of receiving distributions
     pursuant to the Agreement and for all other purposes whatsoever, and
     neither the Depositor nor the Trustee will be affected by notice to the
     contrary.

          The Agreement may be amended from time to time by the Depositor, the
     Servicer and the Trustee, without the consent of any of the
     Certificateholders, to cure any ambiguity, to correct or supplement any
     provisions therein which may be inconsistent with the other provisions
     therein, to ensure continuing treatment of each REMIC included in the Trust
     Fund as a REMIC, or to make any other provisions with respect to matters or
     questions arising under the Agreement which are not materially inconsistent
     with the provisions of the Agreement, provided that such action does not,
     as evidenced by an Opinion of Counsel, adversely affect in any material
     respect the interests of any Certificateholder.

          The Agreement may also be amended from time to time by the Depositor,
     the Servicer and the Trustee, with the consent of the Holders of
     Certificates evidencing in the aggregate not less than 66 2/3% of the
     Percentage Interests of each Class of Certificates affected thereby, for
     the purpose of adding any provisions to or changing in any manner or
     eliminating any of the provisions of the Agreement or of modifying in any
     manner the rights of the Holders of Certificates of such Class; provided,
     however, that no such amendment may (i) reduce in any


                                       A-7

<PAGE>

     manner the amount of, or delay the timing of, payments received on Mortgage
     Loans which are 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 clause (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) change the percentage specified in
     clause (ii) of the third paragraph of Section 10.01 of the Agreement,
     without the consent of the Holders of all Certificates of such Class then
     outstanding.

     The Class A (other than the Class R Certificates), Class M, and Class B
Certificates are issuable only in registerable form, in minimum denominations of
$25,000 in initial Certificate Principal Amount and in integral multiples of $1
in excess thereof, registered in the name of the nominee of the Clearing Agency,
which shall maintain such Certificates through its book-entry facilities. The
Class R Certificates are issuable in minimum denominations of $100 and shall be
maintained in physical, fully registered form. The Class P Certificates are
issuable in minimum denominations of 100% and shall be maintained in physical,
fully registered form. The Class C Certificates are issuable in minimum
denominations of 25% and shall be maintained in physical, fully registered form.

          For federal income tax purposes, the Trust Fund will include multiple
     "real estate mortgage investment conduits" (each, a "REMIC"). The REMIC
     Regular Interests will represent "regular interests" in one of the REMICs
     included in the Trust Fund. The Class R Certificate will represent the sole
     class of "residual interest" in each of the REMICs.

          The obligations and responsibilities of the Depositor, the Servicer
     and the Trustee under the Agreement shall terminate upon the earlier of (a)
     the exercise by the Trustee of 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 under the Agreement continue beyond the earlier of (i) the
     expiration of 21 years from the death of the last survivor of the

                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

evidencing an ownership interest in distributions allocable to the Class B[_]
Certificates with respect to a pool of conventional, sub-prime mortgage loans
formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

     Unless this Certificate is presented by an authorized representative of the
Depository Trust Company, a New York corporation ("DTC"), to the Trustee for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC (and any payment is made to Cede & Co. or to
such other entity as is requested by an authorized representative of DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co. has an interest
herein.

     This certifies that CEDE & CO. is the registered owner of the ownership
interest (the "Ownership Interest") evidenced by this Certificate (obtained by
dividing the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class B[_] Certificates) in certain distributions
with respect to a pool of conventional, sub-prime mortgage loans (the "Mortgage
Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc. (hereinafter
called the "Depositor"), and certain other property held in trust for the
benefit of Certificateholders (collectively, the "Trust Fund"). The Mortgage
Loans are serviced by Home Loan Services, Inc. (the "Servicer") and are secured
by first-lien mortgages on Mortgaged Properties. The Trust Fund was created
pursuant to a pooling and servicing agreement (the "Agreement"), dated as of
June 1, 2007, between the Depositor, the Servicer and LaSalle Bank National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
the capitalized terms used herein have the meanings assigned in the Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, Class B[_]  (the "Class B[_]
Certificates") and is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which Agreement such Holder is
bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in July 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered on the Record Date (as such term is defined in the Agreement).


                                      A-12

<PAGE>

     Distributions on this Certificate will be made either by wire transfer in
immediately available funds to the account of such certificateholder at a bank
or other depository institution having appropriate wire transfer facilities or,
in the case of any certificateholder that has so notified the Trustee in writing
in accordance with the Agreement, by check mailed to the address of the person
entitled to distributions as it appears on the Certificate Register; provided,
however, that the final distribution in retirement of the certificates will be
made only upon presentation and surrender of this Certificate at the office of
the Trustee or such other address designated in writing by the Trustee. On each
Distribution Date, a holder of this Certificate will receive such holder's
Percentage Interest of the amounts required to be distributed with respect to
the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

     Reference is hereby made to the further provisions of this Certificate set
forth on the reverse hereof which further provisions shall for all purposes have
the same effect as if set forth at this place.

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

         MERRILL LYNCH FIRST FRANKLIN MORTGAGE LOAN TRUST, SERIES 2007-4
                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, issued in one or more Classes of Class
A Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced hereby, and the rights, duties and
immunities of the Trustee.

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66 2/3% of the Percentage Interests of
each Class of Certificates affected thereby for the purpose of adding any
provisions to or changing in any manner or eliminating any of the


                                      A-15

<PAGE>

provisions of the Agreement or of modifying in any manner the rights of the
Holders of Certificates of such Class; provided, however, that no such amendment
may (i) reduce in any manner the amount of, or delay the timing of, payments
received on Mortgage Loans which are 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 clause (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) change the percentage specified
in clause (ii) of the third paragraph of Section 10.01 of the Agreement, without
the consent of the Holders of all Certificates of such Class then outstanding.

          The Class A (other than the Class R Certificates), Class M, and Class
     B Certificates are issuable only in registerable form, in minimum
     denominations of $25,000 in initial Certificate Principal Amount and in
     integral multiples of $1 in excess thereof, registered in the name of the
     nominee of the Clearing Agency, which shall maintain such Certificates
     through its book-entry facilities. The Class R Certificates are issuable in
     minimum denominations of $100 and shall be maintained in physical, fully
     registered form. The Class P Certificates are issuable in minimum
     denominations of 100% and shall be maintained in physical, fully registered
     form. The Class C Certificates are issuable in minimum denominations of 25%
     and shall be maintained in physical, fully registered form.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of 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 under the Agreement's 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.

         MERRILL LYNCH FIRST FRANKLIN MORTGAGE LOAN TRUST, SERIES 2007-4
                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, issued in one or more Classes of Class
A Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced hereby, and the rights, duties and
immunities of the Trustee.

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66 2/3% of the Percentage Interests of
each Class of Certificates affected thereby, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Agreement or of modifying in any manner the rights of the Holders of
Certificates of such Class; provided, however, that no such amendment may (i)
reduce in any manner the amount of, or delay the timing of, payments received on
Mortgage Loans which are


                                      A-24

<PAGE>

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 clause (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) change
the percentage specified in clause (ii) of the third paragraph of Section 10.01
of the Agreement, without the consent of the Holders of all Certificates of such
Class then outstanding.

     The Class A (other than the Class R Certificates), Class M, and Class B
Certificates are issuable only in registerable form, in minimum denominations of
$25,000 in initial Certificate Principal Amount and in integral multiples of $1
in excess thereof, registered in the name of the nominee of the Clearing Agency,
which shall maintain such Certificates through its book-entry facilities. The
Class R Certificates are issuable in minimum denominations of $100 and shall be
maintained in physical, fully registered form. The Class P Certificates are
issuable in minimum denominations of 100% and shall be maintained in physical,
fully registered form. The Class C Certificates are issuable in minimum
denominations of 25% and shall be maintained in physical, fully registered form.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC"). The REMIC Regular
Interests will represent "regular interests" in one of the REMICs included in
the Trust Fund. The Class R Certificate will represent the sole class of
"residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of 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 under the Agreement 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.

         MERRILL LYNCH FIRST FRANKLIN MORTGAGE LOAN TRUST, SERIES 2007-4
                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, issued in one or more Classes of Class
A Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced hereby, and the rights, duties and
immunities of the Trustee.

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer the Trustee, with the consent of the Holders of Certificates evidencing
in the aggregate not less than 66 2/3% of the Percentage Interests of each Class
of Certificates affected thereby, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of the Agreement or
of modifying in any manner the rights of the Holders of Certificates of such
Class; provided, however, that no such amendment may (i) reduce in any manner
the amount of, or delay the timing of, payments received on Mortgage Loans which
are 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 clause (i), without the consent of the Holders


                                      A-32

of Certificates of such Class evidencing 66 2/3% or more of the Voting Rights of
such Class or (iii) change the percentage specified in clause (ii) of the third
paragraph of Section 10.01 of the Agreement, without the consent of the Holders
of all Certificates of such Class then outstanding.

Certificates are issuable only in registerable form, in minimum denominations of

denominations of 25% and shall be maintained in physical, fully registered form.

estate mortgage investment conduits" (each, a "REMIC"). The REMIC Regular
Interests will represent "regular interests" in one of the REMICs included in
the Trust Fund. The Class R Certificate will represent the sole class of
"residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of 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 under the Agreement continue beyond the earlier of (i) the

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.

evidencing an ownership interest in distributions allocable to the Class R
Certificates with respect to a pool of conventional, sub-prime mortgage loans
formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

     This certifies that MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED, as
nominee for Merrill Lynch Funding Corporation, is the registered owner of the
ownership interest (the "Ownership Interest") evidenced by this Certificate
(obtained by dividing the Original Denomination of this Certificate by the
aggregate Initial Certificate Balance of all Class R Certificates) in certain
distributions with respect to a pool of conventional, sub-prime mortgage loans
(the "Mortgage Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc.
(hereinafter called the "Depositor"), and certain other property held in trust
for the benefit of Certificateholders (collectively, the "Trust Fund"). The
Mortgage Loans are serviced by Home Loan Services, Inc. (the "Servicer") and are
secured by first-lien mortgages on the Mortgaged Properties. The Trust Fund was
created pursuant to a pooling and servicing agreement (the "Agreement"), dated
as of June 1, 2007, among the Depositor, the Servicer and LaSalle Bank National
Association ("LB"), as as trustee (the "Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, Class R (the "Class R Certificate") and
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which Agreement such Holder is bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in July 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered on the Record Date (as such term is defined in the Agreement).

     Distributions on this Certificate will be made either by wire transfer in
immediately available funds to the account of such certificateholder at a bank
or other depository institution having appropriate wire transfer facilities or,
in the case of any certificateholder that has so notified the Trustee in writing
in accordance with the Agreement, by check mailed to the address of the person
entitled to distributions as it appears on the Certificate Register; provided,
however, that the final distribution in retirement of the certificates will be
made only upon presentation and surrender of this Certificate at the office of
the Trustee or such other address designated in writing by the Trustee. On each
Distribution Date, a holder of this Certificate will receive such holder's
Percentage Interest of the amounts required to be distributed with respect to
the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

     Reference is hereby made to the further provisions of this Certificate set
forth on the reverse hereof which further provisions shall for all purposes have
the same effect as if set forth at this place.

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

         MERRILL LYNCH FIRST FRANKLIN MORTGAGE LOAN TRUST, SERIES 2007-4
                     MORTGAGE LOAN ASSET-BACKED CERTIFICATES

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch First Franklin Mortgage Loan Trust, Series 2007-4
Mortgage Loan Asset-Backed Certificates, issued in one or more Classes of Class
A Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced hereby, and the rights, duties and
immunities of the Trustee.

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66 2/3% of the Percentage Interests of
each Class of Certificates affected thereby, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the


                                      A-40

<PAGE>

provisions of the Agreement or of modifying in any manner the rights of the
Holders of Certificates of such Class; provided, however, that no such amendment
may (i) reduce in any manner the amount of, or delay the timing of, payments
received on Mortgage Loans which are 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 clause (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) change the percentage specified
in clause (ii) of the third paragraph of Section 10.01 of the Agreement, without
the consent of the Holders of all Certificates of such Class then outstanding.

     The Class A (other than the Class R Certificates), Class M, and Class B
Certificates are issuable only in registerable form, in minimum denominations of
$25,000 in initial Certificate Principal Amount and in integral multiples of $1
in excess thereof, registered in the name of the nominee of the Clearing Agency,
which shall maintain such Certificates through its book-entry facilities. The
Class R Certificates are issuable in minimum denominations of $100 and shall be
maintained in physical, fully registered form. The Class P Certificates are
issuable in minimum denominations of 100% and shall be maintained in physical,
fully registered form. The Class C Certificates are issuable in minimum
denominations of 25% and shall be maintained in physical, fully registered form.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC"). The REMIC Regular
Interests will represent "regular interests" in one of the REMICs included in
the Trust Fund. The Class R Certificate will represent the sole class of
"residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of 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 under the Agreement 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.

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.

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

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

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

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

interest; and

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

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

[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

          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

     _______________________ (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.

any general solicitation by means of general advertising or in any other manner

violation of Similar Law, and will not subject the Trustee, the Servicer, the
NIMs Insurer or the Depositor to any obligation in addition to those expressly

     (i)  Market Quotation and the Second Method will apply, provided, however,
          that, notwithstanding anything to the contrary in this Agreement, if
          an Early Termination Date has been designated as a result of a
          Derivative Provider Trigger Event, the following provisions will
          apply:

          (A)  Section 6(e) is hereby amended by inserting on the first line
               thereof the words "or is effectively designated" after "If an
               Early Termination Date occurs";

          (B)  The definition of Market Quotation in Section 14 shall be deleted
               in its entirety and replaced with the following:

               "MARKET QUOTATION" means, with respect to one or more Terminated
               Transactions, and a party making the determination, an amount
               determined on the basis of one or more Firm Offers from Reference
               Market-makers that are Eligible Replacements. Each Firm Offer
               will be (1) for an amount that would be paid to Party B
               (expressed as a negative number) or by Party B (expressed as a
               positive number) in consideration of an agreement between Party B
               and such Reference Market-maker to enter into a Replacement
               Transaction, and (2) made on the basis that Unpaid Amounts in
               respect of the Terminated Transaction or group of Transactions
               are to be excluded but, without limitation, any payment or
               delivery that would, but for the relevant Early Termination Date,
               have been required (assuming satisfaction of each applicable
               condition precedent) after that Early Termination Date are to be
               included. The party making the determination (or its agent) will
               request each Reference Market-maker that is an Eligible
               Replacement to provide its Firm Offer to the extent reasonably
               practicable as of the same day and time (without regard to
               different time zones) on or as soon as reasonably practicable
               after the designation or occurrence of the relevant Early
               Termination Date. The day and time as of which those Firm Offers
               are to be provided (the "bid time") will be selected in good
               faith by the party obliged to make a determination under Section
               6(e), and, if each party is so obliged, after consultation with
               the other. If at least one Firm Offer from an Approved
               Replacement (which, if accepted, would determine the Market
               Quotation) is provided at the bid time, the Market Quotation will
               be the Firm Offer (among such Firm Offers as specified in clause
               (C) below) actually accepted by Party B no later than the
               Business Day immediately preceding the Early Termination Date. If
               no Firm Offer from an Approved Replacement (which, if accepted,
               would determine the Market Quotation) is provided at the bid
               time, it will be deemed that the Market Quotation in respect of
               such Terminated Transaction or group of Transactions cannot be
               determined.

          (C)  If more than one Firm Offer from an Approved Replacement (which,
               if accepted, would determine the Market Quotation) is provided at
               the bid time, Party B shall accept the Firm Offer (among such
               Firm Offers) which would require either (x) the lowest payment by
               Party B to the Reference Market-maker, to the extent Party B
               would be required to make a payment to the Reference Market-maker
               or (y) the highest payment from the Reference Market-maker to
               Party B, to the extent the Reference Market-maker would be
               required to make a payment to Party B. If only one Firm Offer
               from an Approved Replacement (which, if accepted, would determine
               the Market Quotation) is provided at the bid time, Party B shall
               accept such Firm Offer.

          (D)  If Party B requests Party A in writing to obtain Market
               Quotations, Party A shall use its reasonable efforts to do so.

          (E)  If the Settlement Amount is a negative number, Section 6(e)(i)(3)
               shall be deleted in its entirety and replaced with the following:

               "(3) Second Method and Market Quotation. If the Second Method and
               Market Quotation apply, (I) Party B shall pay to Party A an
               amount equal to the absolute value of the Settlement Amount in
               respect of the Terminated Transactions, (II) Party B shall pay to


                                      Q-1-5

<PAGE>

               Party A the Termination Currency Equivalent of the Unpaid Amounts
               owing to Party A and (III) Party A shall pay to Party B the
               Termination Currency Equivalent of the Unpaid Amounts owing to
               Party B; provided, however, that (x) the amounts payable under
               the immediately preceding clauses (II) and (III) shall be subject
               to netting in accordance with Section 2(c) of this Agreement and
               (y) notwithstanding any other provision of this Agreement, any
               amount payable by Party A under the immediately preceding clause
               (III) shall not be netted against any amount payable by Party B
               under the immediately preceding clause (I)."

          (F)  In determining whether or not a Firm Offer satisfies clause
               (B)(y) of the definition of Replacement Transaction and whether
               or not a proposed transfer satisfies clause (e)(B)(y) of the
               definition of Permitted Transfer, Party B shall act in a
               commercially reasonable manner.

(g)  "TERMINATION CURRENCY" means USD.

(h)  ADDITIONAL TERMINATION EVENTS. Additional Termination Events will apply as
     provided in Part 5(c).

          under the Pooling and Servicing Agreement (such consent not to be
          unreasonably withheld), an amendment is made to the Pooling and
          Servicing Agreement which amendment could reasonably be expected to

          (y) Party A fails to provide updated Swap Financial Disclosure within
          the time period set forth in Part 5(e)(iii) and such failure is not
          remedied on or before the third Local Business Day after notice of
          such failure is given to Party A, then an Additional Termination Event
          shall have occurred with respect to Party A and Party A shall be the

          required to be made through and including the Early Termination Date
          designated as a result of this Additional Termination Event; provided,
          for the avoidance of doubt, that any such payments or deliveries that

          treated as Unpaid Amounts in determining the amount payable in respect

<PAGE>

          amount payable by either Party B or Party A in respect of the related
          Early Termination Date in connection with this Additional Termination
          Event; provided, however, that the amount payable by Party B, if any,

          notwithstanding anything to the contrary in this Agreement, any amount

          following the maturity date for the Mortgage Loan with the latest

          Class A Certificates, in either case to the extent required pursuant
          to the terms of the Pooling and Servicing Agreement to be paid to the
          Class A Certificates, then an Additional Termination Event shall have
          occurred with respect to Party B, Party B shall be the sole Affected
          Party and all Transactions hereunder shall be Affected Transactions.

(d)  REQUIRED RATINGS DOWNGRADE EVENT. If a Required Ratings Downgrade Event has

          Depositor requests from Party A the applicable financial information
          described in Item 1115 of Regulation AB (such request to be based on a
          reasonable determination by Depositor, in good faith, that such
          information is required under Regulation AB) (the "Swap Financial
          Disclosure").

          Agreement and subject to prior notification to the Swap Rating
          Agencies, which entity (or a guarantor therefor) satisfies the Rating

          from reports filed pursuant to the Exchange Act.

     (iv) If Party A provides Swap Financial Disclosure pursuant to Part
          5(e)(iii)(1) above, Party A shall provide to Depositor any updated

          Disclosure to Depositor in accordance with Part 5(e)(iii)(a) or causes
          its affiliate to provide Swap Financial Disclosure to Depositor in
          accordance with Part 5(e)(iii)(c), it will indemnify and hold harmless

          damages and liabilities caused by any untrue statement or alleged
          untrue statement of a material fact contained in such Swap Financial
          Disclosure or caused by any omission or alleged omission to state in
          such Swap Financial Disclosure a material fact required to be stated
          therein or necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading.

(f)  TRANSFERS.

     (i)  Section 7 is hereby amended to read in its entirety as follows:

          "Neither this Agreement nor any interest or obligation in or under
          this Agreement may be transferred (whether by way of security or
          otherwise) by either party unless (a) the prior written consent of the
          other party is obtained and (b) the Rating Agency Condition has been
          satisfied with respect to S&P, except that:

          (a)  Party A may make a Permitted Transfer (1) pursuant to Section
               6(b)(ii) (as amended herein) or Part 5(e), (2) pursuant to a
               consolidation or amalgamation with, or merger with or into, or
               transfer of all or substantially all its assets to, another
               entity (but without prejudice to any other right or remedy under
               this Agreement), or (3) at any time at which no Relevant Entity
               has credit ratings at least equal to the Approved Ratings
               Threshold;

          (b)  Party B may transfer its rights and obligations hereunder (1) in
               connection with a transfer pursuant to Section 8.08 of the
               Pooling and Servicing Agreement, and

          (c)  a party may make such a transfer of all or any part of its
               interest in any amount payable to it from a Defaulting Party
               under Section 6(e).

          Any purported transfer that is not in compliance with this Section
          will be void.

<PAGE>

     (ii) If an Eligible Replacement has made a Firm Offer (which remains an
          offer that will become legally binding upon acceptance by Party B) to
          be the transferee pursuant to a Permitted Transfer, Party B shall, at
          Party A's written request and at Party A's expense, take any
          reasonable steps required to be taken by Party B to effect such
          transfer.

(g)  LIMITED RECOURSE; NON-RECOURSE. Party A acknowledges and agrees that,
     notwithstanding any provision in this Agreement to the contrary, the
     obligations of Party B hereunder are limited recourse obligations of Party
     B, payable solely from the Swap Account and the proceeds thereof, in
     accordance with the priority of payments and other terms of the Pooling and
     Servicing Agreement and that Party A will not have any recourse to any of
     the directors, officers, agents, employees, shareholders or affiliates of
     Party B with respect to any claims, losses, damages, liabilities,
     indemnities or other obligations in connection with any transactions
     contemplated hereby. In the event that the Swap Account and the proceeds
     thereof, should be insufficient to satisfy all claims outstanding and
     following the realization of Swap Account and the proceeds thereof, any
     claims against or obligations of Party B under this Agreement or any other
     confirmation thereunder still outstanding shall be extinguished and
     thereafter not revive. The Supplemental Interest Trust Trustee shall not

     TIMING OF PAYMENTS BY PARTY B UPON EARLY TERMINATION. Notwithstanding
     anything to the contrary in Section 6(d)(ii), to the extent that all or a
     portion (in either case, the "Unfunded Amount") of any amount that is
     calculated as being due in respect of any Early Termination Date under
     Section 6(e) from Party B to Party A will be paid by Party B from amounts
     other than any upfront payment paid to Party B by an Eligible Replacement
     that has entered into a Replacement Transaction with Party B, then such
     Unfunded Amount shall be due on the next subsequent Distribution Date
     following the date on which the payment would have been payable as
     determined in accordance with Section 6(d)(ii), and on any subsequent
     Distribution Dates until paid in full (or if such Early Termination Date is
     the final Distribution Date, on such final Distribution Date); provided,

     payment will be payable on such Distribution Date.

(i)  RATING AGENCY NOTIFICATIONS. Notwithstanding any other provision of this
     Agreement, no Early Termination Date shall be effectively designated
     hereunder by Party B and no transfer of any rights or obligations under

     been provided prior written notice of such designation or transfer.

     Part 1(f)(i)(D) hereof, and notwithstanding any other provision of this

     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. Section 6(e) shall be
     amended by deleting the following sentence: "The amount, if any, payable in
     respect of an Early Termination Date and determined pursuant to this
     Section will be subject to any Set-off.".

(k)  AMENDMENT. Notwithstanding any provision to the contrary in this Agreement,
     no amendment of either this Agreement or any Transaction under this
     Agreement shall be permitted by either party unless each of the Rating
     Agencies has been provided prior written notice of the same and the Rating
     Agency Condition is satisfied with respect to S&P.

(l)  NOTICE OF CERTAIN EVENTS OR CIRCUMSTANCES. Each Party agrees, upon learning
     of the occurrence or existence of any event or condition that constitutes
     (or that with the giving of notice or passage of time or both would
     constitute) an Event of Default or Termination Event with respect to such
     party, promptly to give the other Party and to each Rating Agency notice of
     such event or condition; provided that failure to provide

     notice of such event or condition pursuant to this Part 5(l) shall not
     constitute an Event of Default or a Termination Event.

(m)  PROCEEDINGS. No Relevant Entity shall institute against, or cause any other
     person to institute against, or join any other person in instituting

     reorganization, arrangement, insolvency or liquidation proceedings or other
     proceedings under any federal or state bankruptcy or similar law for a
     period of one year (or, if longer, the applicable preference period) and
     one day following payment in full of the Certificates and any Notes. This
     provision will survive the termination of this Agreement.

     understood and agreed by the parties hereto that (a) this Agreement is
     executed and delivered by LaSalle Bank National Association ("LaSalle") not

     powers and authority conferred and invested in it thereunder; (b) LaSalle
     has been directed pursuant to the Pooling and Servicing Agreement to enter
     into this Agreement and to perform its obligations hereunder; (c) each of
     the representations, warranties, covenants, undertakings and agreements

     intended not as personal representations, undertakings and agreements by
     LaSalle but is made and intended for the purpose of binding only the
     Supplemental Interest Trust; and (d) nothing herein contained shall be
     construed as creating any liability on LaSalle, individually or personally,
     to perform any covenant either expressed or implied contained herein, all
     such liability, if any, being expressly waived by the parties who are
     signatories to this Agreement and by any person claiming by, through or
     under such parties and (e) under no circumstances shall LaSalle,
     individually, be personally liable for the payment of any indemnity,
     indebtedness, fees or expenses of the Supplemental Interest Trust or be
     liable for the breach or failure of any obligations, representation,
     warranty or covenant made or undertaken by the Supplemental Interest Trust
     under this Agreement.

(o)  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) in any
     respect, 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; provided, however, that this severability provision shall not be
     applicable if any provision of Section 2, 5, 6, or 13 (or any definition or
     provision in Section 14 to the extent it relates to, or is used in or in
     connection with any such Section) shall be so held to be invalid or
     unenforceable.

     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.

(p)  AGENT FOR PARTY B. Party A acknowledges that the Depositor has appointed
     Supplemental Interest Trust Trustee as agent under the Pooling and
     Servicing Agreement to carry out certain functions on behalf of Party B,

               (III) if, on any Valuation Date, the Delivery Amount equals or
