     POOLING AND SERVICING AGREEMENT, dated as of April 1, 2007 (the
"Agreement"), among MERRILL LYNCH MORTGAGE INVESTORS, INC., a Delaware
corporation, as depositor (the "Depositor"), WILSHIRE CREDIT CORPORATION, a
Nevada corporation, as servicer (the "Servicer"), and U.S. BANK NATIONAL
ASSOCIATION, a national banking association, as trustee (the "Trustee").

     The Depositor is the owner of the Trust Fund that is hereby conveyed to the
Trustee in return for the Certificates. The Trust Fund for federal income tax
purposes will consist of (i) three real estate mortgage investment conduits in a
tiered structure, (ii) the right to receive the payments distributable to the
Class P Certificates pursuant to Section 4.04(b)(i) hereof, (iii) each Corridor
Contract and the Corridor Contract Account, (iv) the grantor trusts described in
Section 2.07 hereof and (v) the Supplemental Interest Trust, which in turn will
hold the Swap Agreement. The SWAP REMIC will consist of all of the assets
constituting the Trust Fund (other than the assets described in clauses (ii),
(iii), (iv) and (v) above, other than the SWAP REMIC Regular Interests and other
than the Lower Tier REMIC Regular Interests) and will be evidenced by the SWAP
REMIC Regular Interests (which will be uncertificated and will represent the
"regular interests" in the SWAP REMIC) and the Class SWR Interest as the single
"residual interest" in the SWAP REMIC. The Lower Tier REMIC will consist of SWAP
REMIC Regular Interests and will be evidenced by the Lower Tier REMIC Regular
Interests (which will be uncertificated and will represent the "regular
interests" in the Lower Tier REMIC) and the Class LTR Interest as the single
"residual interest" in the Lower Tier REMIC. The Trustee will hold the Lower
Tier REMIC Regular Interests. The Upper Tier REMIC will consist of the Lower
Tier REMIC Regular Interests and will be evidenced by the REMIC Regular
Interests (which will represent the "regular interests" in the Upper Tier REMIC)
and the Residual Interest as the single "residual interest" in the Upper Tier
REMIC. The Class R Certificate will represent beneficial ownership of the Class
SWR Interest, the Class LTR Interest and the Residual Interest. The "latest
possible maturity date" for federal income tax purposes of all interests created
hereby will be the Latest Possible Maturity Date.

     All covenants and agreements made by the Sponsor in the Sale Agreement and
by the Depositor and the Trustee herein with respect to the Mortgage Loans and
the other property constituting the Trust Fund are for the benefit of the
Holders from time to time of the Certificates and, to the extent provided
herein, the NIMs Insurer.

(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

     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 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.

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

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

annum rate equal to the product of (i) 12, (ii) the quotient of (x) the total

                                   ARTICLE II
          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).

     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 so assigned:

     (a) all pages of the original Mortgage Note, signed by the borrower(s) and
endorsed, "Pay to the order of blank, without recourse" and signed in the name
of the prior holder by an authorized officer. Such signature on the endorsement
shall be an original signature of such authorized officer and have printed the
endorser's name, title and company name. To the extent that there is no room on
the face of the Mortgage Note for endorsements, the endorsement may be contained
on an allonge, if the law by which such Mortgage Note is governed so permits.
The Mortgage Note shall include all intervening endorsements showing a complete
chain of title from the originator to the Sponsor;

     (b) all original pages of any riders referred to in the Mortgage Note;

     (c) for each Mortgage Loan that is not a MOM Mortgage Loan, the original
recorded Mortgage, together with all riders referred to in the Mortgage, and
legal description, with evidence of

                                       62

<PAGE>

recording thereon or if the original is not available, a copy certified by the
applicable public recording office. If the original Mortgage has not yet been
returned from the recording office, a copy of the original Mortgage, together
with all riders thereto, that has been delivered for recording in the
appropriate recording office of the jurisdiction in which the Mortgaged Property
is located;

     (d) for each Mortgage Loan that is not a MERS Mortgage Loan, the original
Mortgage Assignment, executed in blank, in form and substance acceptable for
recording and signed in the name of the last endorsee by an authorized officer;

     (e) the policy of title insurance (or a preliminary title report if the
original title insurance policy has not been received from the title insurance
company);

     (f) for each Mortgage Loan that is not a MERS Mortgage Loan, originals of
any intervening Mortgage Assignments, with evidence of recording thereon, or if
the original is not available, a copy certified by the applicable public
recording office. If the original intervening assignment has not yet been
returned from the recording office, a copy of such assignment which has been
sent for recording in the appropriate jurisdiction in which the Mortgaged
Property is located, showing a complete chain of title from the originator to
the Seller;

     (g) in the case of each MOM Loan, the original Mortgage, together with all
riders thereto, with evidence of recording thereon, noting the presence of the
MIN of the Mortgage Loan and language indicating that the Mortgage Loan is a MOM
Loan or if the original Mortgage is not available, a copy certified by the
applicable public recording office. If the original Mortgage has not yet been
returned from the recording office, a copy of such Mortgage which has been sent
for recording in the appropriate jurisdiction in which the Mortgaged Property is
located;

     (h) in the case of each MERS Mortgage Loan that is not a MOM Loan, the
original Mortgage Assignment or if the original Mortgage is not available, a
copy certified by the applicable public recording office, with evidence of
recording thereon, and all intervening Mortgage Assignments, with evidence of
recording thereon, showing a complete chain of title from the originator to
MERS;

     (i) all original pages of assumption, modification, consolidation or
extension agreements, if any, with evidence of recording thereon;

     (j) with respect to a Mortgage Loan that, according to the Mortgage Loan
Schedule is covered by a primary mortgage insurance policy, the original or a
copy of the policy of primary mortgage insurance; and

     (k) if the Mortgage Note or the Mortgage has been signed by any Person on
behalf of the Mortgagor, the original power of attorney or other instrument that
authorized and empowered such Person to sign, or a copy of such power of
attorney that has been delivered for recording in the appropriate recording
office of the jurisdiction in which the Mortgaged Property is located.

     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

                                       63

<PAGE>

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.

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

     It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Sponsor to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of the Sponsor deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of the
Sponsor to the Depositor deemed to be secured by said pledge and that the
Trustee shall be deemed to be an independent custodian for purposes of
perfection of the security interest granted to the Depositor. If the conveyance
of the Mortgage Loans from the Depositor to the Trustee is characterized as a
pledge, it is the intention of this Agreement that this Agreement shall
constitute a security agreement under applicable law, and that the Depositor
shall be deemed to have granted to the Trustee a first priority security
interest in all of the Depositor's right, title and interest in, to and under
the Mortgage Loans, all payments of principal of or interest on such Mortgage
Loans, all other rights relating to and payments made in respect of the Trust
Fund, and all proceeds of any thereof. If the trust created by this Agreement
terminates prior to the satisfaction of the claims of any Person in any
Certificates, the security interest created hereby shall continue in full force
and effect and the Trustee shall be deemed to be the collateral agent for the
benefit of such Person.

     In addition to the conveyance made in the first paragraph of this
Section 2.01, the Depositor does hereby convey, assign and set over to the
Trustee for the benefit of the Certificateholders its rights and interests under
the Sale Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement and the benefit
of the repurchase obligations and the obligation of the Sponsor contained in the
Sale Agreement to take, at the request of the Depositor or the Trustee, all
action on its part which is reasonably necessary to ensure the enforceability of
a Mortgage Loan. The Trustee hereby accepts such assignment, and shall be
entitled to exercise all rights of the Depositor under the Sale Agreement as if,
for such purpose, it were the Depositor. The foregoing sale,

                                       64

<PAGE>

transfer, assignment, set-over, deposit and conveyance does not and is not
intended to result in creation or assumption by the Trustee of any obligation of
the Depositor, the Sponsor, or any other Person in connection with the Mortgage
Loans or any other agreement or instrument relating thereto.

     The parties hereto agree and understand that it is not intended that any
Mortgage Loan be included in the Trust that is, without limitation, a "High-Cost
Home Loan" as defined by the Home Ownership and Equity Protection Act of 1994 or
any other applicable anti-predatory lending laws, including but not limited to
(i) a "High-Cost Home Loan" as defined in the New Jersey Home Ownership Act
effective November 27, 2003; (ii) a "High-Cost Home Loan" as defined in the New
Mexico Home Loan Protection Act effective January 1, 2004; (iii) a "High-Cost
Home Loan" as defined in the Massachusetts Predatory Home Loan Practices Act
effective November 7, 2004; (iv) a "High-Cost Home Loan" as defined by the
Indiana High Cost Home Loan Law effective January 1, 2005 or (v) a "High-Cost
Home Loan" as defined by the Illinois High Risk Home Loan Act effective January
1, 2004.

     SECTION 2.02. Acceptance by Trustee of the Mortgage Loans.

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

     The Trustee acknowledges receipt of the three Corridor Contracts (forms of
which are attached hereto as Exhibits O-1, O-2 and O-3) and is hereby instructed
to enter into the Corridor Contracts, not in its individual capacity, but solely
as Trustee of the Issuing Entity. The Trustee also acknowledges receipt of the
Sale Agreement.

     The Trustee acknowledges receipt of the Swap Agreement that will be held in
the Supplemental Interest Trust and is hereby instructed to enter into the Swap
Agreement, not in its individual capacity, but solely as the 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 to ascertain and to certify, within seventy (70) days of
the Closing Date, to the NIMs Insurer, the Depositor and the Servicer that all
documents required by Section 2.01, except those listed on the exception report
attached thereto, have been executed and received, and that such documents
relate to the Mortgage Loans identified in Exhibit B that have been conveyed to
it. 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 Sponsor and the Depositor. In addition, the
Trustee shall also notify the NIMs Insurer, the Servicer, the Sponsor and the
Depositor if the original Mortgage with evidence of recording thereon with
respect to a Mortgage Loan is not received within seventy (70) days of the
Closing Date; if it has not been received because of a delay caused by the
public recording office where such Mortgage has been delivered for recordation,
the Depositor shall deliver or cause to be delivered to the Trustee written
notice stating that such Mortgage has been delivered to the appropriate public
recording office for recordation and thereafter the Depositor shall deliver or
cause to be delivered such Mortgage with evidence of recording thereon upon
receipt thereof from the public

                                       65

<PAGE>

recording office. The Trustee shall request that the Sponsor correct or cure
such omission, defect or other irregularity, or substitute a Mortgage Loan
pursuant to the provisions of Section 2.03(c), within ninety (90) days from the
date the Sponsor was notified of such omission or defect and, if the Sponsor
does not correct or cure such omission or defect within such period, that the
Sponsor purchase such Mortgage Loan from the Issuing Entity within ninety (90)
days from the date the Trustee notified the Sponsor of such omission, defect or
other irregularity at the Purchase Price of such Mortgage Loan. The Purchase
Price for any Mortgage Loan purchased pursuant to this Section 2.02 shall be
paid to the Servicer and deposited by the Servicer in the Collection Account
promptly upon receipt, and, upon receipt by the Trustee of written notification
of such deposit signed by a Servicing Officer, the Trustee, upon receipt of a
Request for Release, shall promptly release to the Sponsor the related Mortgage
File and the Trustee shall execute and deliver such instruments of transfer or
assignment, without recourse, representation or warranty, as shall be necessary
to vest in the Sponsor or its designee, as the case may be, any Mortgage Loan
released pursuant hereto, and the Trustee shall have no further responsibility
with regard to such Mortgage Loan. It is understood and agreed that the
obligation of the Sponsor to purchase, cure or substitute any Mortgage Loan as
to which a material defect in or omission of a constituent document exists shall
constitute the sole remedy respecting such defect or omission available to the
Trustee on behalf of Certificateholders and the NIMs Insurer. The preceding
sentence shall not, however, limit any remedies available to the
Certificateholders, the NIMs Insurer, the Depositor or the Trustee pursuant to
the Sale Agreement. 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 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 and the Trustee shall not solicit any
such Mortgagor for the purpose of refinancing the related Mortgage Loan. It is
understood and agreed that all rights and benefits relating to the solicitation
of any Mortgagors and the attendant rights, title and interest in and to the
list of Mortgagors and data relating to their Mortgages shall be retained by the
Servicer.

     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.

     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 and the Sale Agreement or the ability of the Depositor to perform
     its obligations under this Agreement and the Sale Agreement in accordance
     with the terms hereof.

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

          (vi) Each Mortgage Loan in Group One has a Stated Principal Balance as
     of the Cut-off Date that complies with the loan limitations of Fannie Mae
     and Freddie Mac as in effect on the Cut-off Date.

     (b) To the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of a representation or warranty of the
Sponsor under the Sale Agreement, the only right or remedy of the Trustee or of
any Certificateholder shall be the Trustee's right to enforce the obligations of
the Sponsor under any applicable representation or warranty made by it. 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,
or the Trustee of a breach of any of representations and warranties set forth in
the Sale Agreement 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 a
breach of any representation or warranty given to the Trustee by the Depositor,
the Sponsor and assigned by the Depositor to the Trustee, the Depositor, or the
Sponsor shall either (a) cure such breach in all material respects, (b)
repurchase such Mortgage Loan or any property acquired in respect thereof from
the Trustee at the Purchase Price or (c) within the two year

                                       67

<PAGE>

period following the Closing Date, substitute a Replacement Mortgage Loan for
the affected Mortgage Loan. In the event of discovery of a breach of any
representation and warranty of the Sponsor or the Depositor, the Trustee shall
enforce its rights under the Sale Agreement or thereunder for the benefit of
Certificateholders and the NIMs Insurer. In the event of a breach of the
representations and warranties with respect to the Mortgage Loans set forth in a
Sale Agreement, the Trustee shall enforce the right of the Issuing Entity to be
indemnified for such breach of representation and warranty. In the event that
such breach relates solely to the unenforceability of a prepayment charge,
amounts received in respect of such indemnity up to the amount of such
prepayment charge shall be distributed pursuant to Section 4.04(b)(i)(B). As
provided in the Sale Agreement, if the Sponsor substitutes for a Mortgage Loan
for which there is a breach of any representations and warranties which
adversely and materially affects the value of such Mortgage Loan and such
substitute mortgage loan is not a Replacement Mortgage Loan, under the terms of
the Sale Agreement, the Sponsor will, in exchange for such substitute Mortgage
Loan, (i) provide the applicable Purchase Price for the affected Mortgage Loan
or (ii) within two years of the Closing Date, substitute such affected Mortgage
Loan with a Replacement Mortgage Loan. Any such substitution shall not be
effected prior to the additional delivery to the Trustee of a Request for
Release substantially in the form of Exhibit I and shall not be effected unless
it is within two years of the Startup Day. As provided in the Sale Agreement,
the Sponsor indemnifies and holds the Issuing Entity, the Trustee, 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 Sponsor relating to a repurchase of a Mortgage Loan other than in
compliance with the terms of this Section 2.03 and the Sale Agreement, to the
extent that any such action causes (i) any federal or state tax to be imposed on
the Issuing Entity or any REMIC provided for herein, including without
limitation, any federal tax imposed on "prohibited transactions" under Section
860F(a)(1) of the Code or on "contributions after the startup day" under Section
860G(d)(1) of the Code, or (ii) any REMIC created hereunder to fail to qualify
as a REMIC at any time that any Certificate is outstanding.

     With respect to any Mortgage Loan repurchased by the Depositor pursuant to
this Agreement or by the Sponsor pursuant to the Sale Agreement, the principal
portion of the funds received by the Servicer in respect of such repurchase of a
Mortgage Loan will be considered a Principal Prepayment and shall be deposited
by the Servicer in the Certificate Account pursuant to Section 3.05. The
Trustee, upon receipt of the full amount of the Purchase Price for a Deleted
Mortgage Loan, or upon receipt of the Mortgage File for a Replacement Mortgage
Loan substituted for a Deleted Mortgage Loan, shall release or cause to be
released and reassign to the Depositor or the Sponsor, as applicable, 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 Trustee, and the Trustee shall not have any 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 Depositor or the Sponsor, as applicable, 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 delivery of such Mortgage File and containing the granting
language set forth in the first sentence of 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 have been executed and received.

                                       68

<PAGE>

     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") shall be delivered by the Sponsor to the
Servicer for deposit into the Collection Account 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.

     The Sponsor shall give or cause to be given written notice to the
Certificateholders that such substitution has taken place, shall amend the
Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from
the terms of this Agreement and the substitution of the Replacement Mortgage
Loan or Replacement Mortgage Loans and shall deliver a copy of such amended
Mortgage Loan Schedule to the NIMs Insurer and the Trustee. Upon such
substitution by the Sponsor, such Replacement Mortgage Loan or Replacement
Mortgage Loans shall constitute part of the Mortgage Pool and shall be subject
in all respects to the terms of this Agreement and the Sale Agreement, including
all applicable representations and warranties thereof included in the Sale
Agreement as of the date of substitution.

     In addition, the Sponsor shall obtain at its own expense and deliver to the
Trustee an Opinion of Counsel addressed to the Trustee to the effect that such
substitution will not (a) cause any federal 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 (b) adversely affect the status of any REMIC provided for herein as a
REMIC. If any such Opinion of Counsel can not be delivered, then such
substitution may only be effected at such time as the required Opinion of
Counsel can be given.

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

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

     SECTION 2.04. Representations and Warranties of the Servicer.

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

          (i) The Servicer is a duly formed corporation and is validly existing
     and in good standing under the laws of the state of its formation 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
     law to effect such qualification and, in any event, is in compliance with
     the doing business laws of any such state, to the extent necessary to
     ensure its ability to enforce each Mortgage Loan, to

                                       69

<PAGE>

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

          (ii) The Servicer has the power and authority to service each Mortgage
     Loan, and to execute, deliver and perform, and to enter into and consummate
     the transactions contemplated by this Agreement and has duly authorized by
     all necessary corporate action on the part of the Servicer the execution,
     delivery and performance of this Agreement; and this 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,
     regulatory body, administrative agency or governmental body having
     jurisdiction over the Servicer; and the Servicer 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
     Servicer's ability to perform or meet any of its obligations under this
     Agreement.

          (iv) The Servicer is an approved servicer of mortgage loans for Fannie
     Mae and is an approved servicer of mortgage loans for Freddie Mac.

          (v) No litigation is pending or, to the best of the Servicer's
     knowledge, threatened, against the Servicer that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement or the ability of the Servicer to service the Mortgage Loans or
     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
     governmental agency or body is required for the execution, delivery and
     performance by the Servicer of, or compliance by the Servicer with, this
     Agreement or the consummation of the transactions contemplated hereby, or
     if any such consent, approval, authorization or order is required, the
     Servicer has obtained the same.

          (vii) 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.

     SECTION 2.05. Substitutions and Repurchases of Mortgage Loans Which 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, at the Depositor's option, 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 shall reconvey to the Depositor 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 in Section 2.03.

     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
to be authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, Certificates duly authenticated by the
Authenticating Agent in authorized denominations evidencing ownership of the
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 SWAP REMIC, the Lower Tier REMIC and
the Upper Tier REMIC as a REMIC. The Trustee shall sign the returns providing
for such elections and such other tax or information returns which 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 SWAP
REMIC, the Lower Tier REMIC and the Upper Tier 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," as defined in Section 860G(a)(9) of the Code, for
purposes of the REMIC Provisions shall be the Closing Date. Each REMIC's fiscal
year shall be the calendar year.

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

                                       71

<PAGE>

     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 the Class A Certificates, Class R
Certificate, Class M Certificates 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
the Class A Certificates, Class R Certificate, Class M Certificates 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, Class M Certificates and Class B Certificates and the
residual interest in the Upper Tier REMIC held by the holder of the Class R
Certificate. This provision is intended to satisfy the requirements of Treasury
Regulations Section 1.860G-2(i) for the treatment of property rights coupled
with REMIC interests to be separately respected and shall be interpreted
consistently with such regulation. On each Distribution Date, to the extent that
any of the Class A Certificates, Class R Certificate, Class M Certificates 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(f) 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

                                       72

<PAGE>

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 R, 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 that 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 Certificates, Class R Certificate, Class
M Certificates and Class B Certificates shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class C Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class C Certificates information regarding their
allocable share, if any, of the income with respect to such grantor trust, (ii)
file or cause to be filed with the Internal Revenue Service Form 1041 (together
with any necessary attachments) and such other forms as may be applicable and
(iii) comply with such information reporting obligations with respect to
payments from such grantor trust to the holders of Class A Certificates, Class R
Certificate, Class M Certificates, Class B Certificates and Class C Certificates
as may be applicable under the Code.

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

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

                                       73

<PAGE>

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 designation "1" in ascending order of their numerical
class designation, in equal amounts to each such class in such numerical
designation, until the principal balance of each such class is reduced to zero.
All losses with respect to the Group One Mortgage Loans shall be allocated among
the SWAP REMIC Regular Interests beginning with the designation "1" in the same
manner that principal distributions are allocated. On each Distribution Date,
the Trustee shall distribute the aggregate Principal Funds with respect to the
Group Two Mortgage Loans first to the Class 2-SW2 Interest until its principal
balance is reduced to zero and then sequentially to each of the other SWAP REMIC
Regular Interests beginning with designation "2" in ascending order of their
numerical class designation, in equal amounts to each such class in such
numerical designation, until the principal balance of each such class is reduced
to zero. All losses with respect to the Group Two Mortgage Loans shall be
allocated among the SWAP REMIC Regular Interests beginning with the designation
"2" in the same 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; 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

                                       74

<PAGE>

Tier REMIC Subordinate 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 Subordinate 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.

          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.

          For purposes of this Section 2.07, (i) the Class LTII1A Interest and
Class LTII1B Interest shall be related to Group One, and (ii) the Class LTII2A
Interest and Class LTII2B Interest shall be related to Group Two.

     (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

                                       75

<PAGE>

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 Class R Certificate,
as applicable, nor for any such Losses resulting from misinformation provided by
the Holder of the Class R Certificate 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 Class R Certificate 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 Class R Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of the Class R Certificate
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 Class R Certificate now or
hereafter existing at law or in equity. Notwithstanding the foregoing, however,
in no event shall the Trustee have any liability (1) for any action or omission
that is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than those arising out of a negligent performance by the Trustee of its
duties and obligations set forth herein, and (3) for any special or
consequential damages to Certificateholders (in addition to payment of principal
and interest on the Certificates).

     SECTION 2.08. 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

                                   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. The Servicer shall represent and protect the interest of the Issuing Entity
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. Notwithstanding anything in
this Agreement to the contrary, the Servicer shall not make or permit any
modification, waiver or amendment of any term of any Mortgage Loan which would
cause any of the REMICs provided for herein to fail to qualify as a REMIC or
result in the imposition of any tax under Section 860G(a) or 860G(d) of the
Code. 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, of partial or full release or
discharge, or of subordination 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. If reasonably required by
the Servicer, the Trustee shall furnish the Servicer with a reasonable number of
powers of attorney in the form attached hereto as Exhibit J and execute such
other documents delivered to it by the Servicer that are necessary or
appropriate to enable the Servicer to carry out its servicing and administrative
duties under this Agreement. Upon receipt of such documents, the Depositor
and/or the Trustee shall execute such documents and deliver them to the
Servicer. The Trustee shall have no liability with respect to any misuse of such
power of attorney, to the extent such use by the Servicer is outside the
authorization provided for in the power of attorney, and shall be indemnified by
the Servicer

                                       77

<PAGE>

for any costs, liabilities or expenses incurred by the Trustee in connection
with any misuse of such power of attorney.

     In accordance with the standards of the preceding paragraph, the Servicer
shall advance or cause to be advanced funds as necessary for the purpose of
effecting the payment of taxes and assessments on any first lien Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further as
provided in Section 3.08. To the extent that a Mortgage does not provide for
escrow payments, (i) the Servicer shall determine whether any such payments are
made by a first lien Mortgagor in a manner and at a time that is necessary to
avoid the loss of the Mortgaged Property due to a tax sale or the foreclosure as
a result of a tax lien and (ii) the Servicer shall ensure that all insurance
required to be maintained on a first lien Mortgaged Property pursuant to this
Agreement is maintained. If any such payment has not been made and the Servicer
receives notice of a tax lien with respect to the Mortgage Loan being imposed,
the Servicer will, to the extent required to avoid loss of the Mortgaged
Property, advance or cause to be advanced funds necessary to discharge such lien
on the Mortgaged Property subject to the Servicer's determination that such
advances will be recoverable. All costs incurred by the Servicer, if any, in
effecting the timely payment of taxes and assessments on the Mortgaged
Properties and related insurance premiums shall not, for the purpose of
calculating monthly distributions to the Certificateholders, be added to the
Stated Principal Balance under the related Mortgage Loans, notwithstanding that
the terms of such Mortgage Loans so permit.

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

     The Servicer will transmit full-file credit reporting data for each
Mortgage Loan pursuant to Fannie Mae Guide Announcement 97-02 and for each
Mortgage Loan, the Servicer agrees that it shall report one of the following
statuses each month as follows: current, delinquent (30-, 60-, 90-days, etc.),
foreclosed or charged-off.

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

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

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

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

                                       78

<PAGE>

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

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

     (a) The Servicer may arrange for the subservicing of any Mortgage Loan by a
subservicer, which may be an Affiliate (each, a "subservicer"), 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 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.

     (b) 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
Subordinate 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 such holder. 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 such holder or
the special servicing advisor designated by such holder may advise the Servicer
with regards to efforts to maximize recoveries with respect to such Mortgage
Loans, including without limitation the commencement of foreclosure proceedings
or other actions.

     (c) 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.

     (d) 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.

     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.

                                       79

<PAGE>

     SECTION 3.04. Trustee to Act as Servicer.

     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 of the Servicer pursuant to
Section 3.10 hereof or any acts or omissions of such 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 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 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 the 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 assume such 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 are not paid by the Servicer pursuant to this Agreement within thirty (30)
days of the date of the Trustee's invoice therefor, such amounts shall be
payable out of the Certificate Account; provided that 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 Section 7.03 of this Agreement and reasonably acceptable to the
NIMs Insurer.

     The Servicer shall, upon request of the Trustee, but at the expense of the
Servicer, 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.

     In the event that the Servicer shall for any reason no longer be the
Servicer hereunder (including by reason of any Event of Default),
notwithstanding anything to the contrary above, the Trustee and the Depositor
hereby agree that within ten (10) Business Days or 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, the Servicing Rights
Pledgee or its designee shall be appointed as successor servicer (provided that
at the time of such appointment the Servicing Rights Pledgee or such designee
meets the requirements of a successor servicer set forth above) and the
Servicing Rights Pledgee agrees to be subject to the terms of this Agreement.

                                       80

<PAGE>

     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 and subject to Section
3.01 hereof, the Servicer may in its discretion (i) waive any late payment
charge or, if applicable, any default interest, or (ii) 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 the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of the Servicer, such default is reasonably foreseeable, the
Servicer, consistent with the standards set forth in Section 3.01, may also
waive, modify or vary any term of such Mortgage Loan (including modifications
that would change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of such Mortgage Loan), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of such Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor (any and all such waivers, modifications, variances,
forgiveness of principal or interest, postponements, or indulgences collectively
referred to herein as "forbearance"), provided, however, that in no event shall
the Servicer grant any such forbearance (other than as permitted by the second
sentence of this Section) with respect to any one Mortgage Loan more than once
in any 12 month period or more than three times over the life of such Mortgage
Loan, and provided, further, 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.

     (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 and other similar laws relating to
creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) the prepayment of the
Mortgage Loan is made in connection with the involuntary sale of the related
Mortgaged Property, or (iv) in the Servicer's reasonable judgment as described
in Section 3.01 hereof, (x) such waiver relates to a default or a reasonably
foreseeable default and (y) such waiver would maximize recovery of total
proceeds taking into account the value of such prepayment charge and related
Mortgage Loan, or (v) the collection of such prepayment charge or portion
thereof, or of a similar type of prepayment charge, 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, only to the
extent that there are no NIM Notes outstanding or to the extent that the
Depositor has notified the Servicer in writing that all previously issued NIM
Notes are no longer outstanding, there is a certificated class action in which a
similar type of prepayment charge is being challenged, or (vi) if sufficient
information is not made available to enable it to collect the prepayment charge.
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

                                       81

<PAGE>

or does not collect all or a portion of a prepayment charge relating to a
Principal Prepayment in full or in part due to any action or omission of the
Servicer, other than as provided above, the Servicer shall deposit the amount of
such prepayment charge (or such portion thereof as had been waived for deposit)
into the Collection Account for distribution in accordance with the terms of
this Agreement.

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

     (d) The Servicer shall establish and initially maintain, on behalf of the
Trustee for the benefit of the Certificateholders, the Collection Account. The
Servicer shall deposit into the 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 related Servicing Fee permitted under Section 3.15, other than interest
     due on the Mortgage Loans on or prior to the Cut-off Date;

          (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(g) in connection with any losses on Permitted Investments;

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

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

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

          (x) all prepayment charges; and

          (xi) 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 all late payment charges, insufficient funds charges and payments in
the nature of assumption fees and charges (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

                                       82

<PAGE>

fees (other than prepayment charges) if collected, need not be remitted by the
Servicer. In the event that the Servicer shall remit any amount not required to
be remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time withdraw or direct the Trustee, or such other
institution maintaining the Collection Account, to withdraw such amount from the
Collection Account, any provision herein to the contrary notwithstanding. The
Servicer shall maintain adequate records with respect to all withdrawals made
pursuant to this Section. All funds deposited in the Collection Account shall be
held in trust for the Certificateholders until withdrawn in accordance with
Section 3.08. In no event shall the Trustee incur liability for withdrawals from
the Collection Account at the direction of the Servicer.

     (e) [Reserved]

     (f) 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 and required to be deposited in the Certificate Account;

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

          (iii) the Auction Termination Amount or Clean Up Call Price payable
     pursuant to Section 9.01.

     Any amounts received by the Trustee prior to 2:30 p.m. New York City time
(or such earlier deadline for investment in the Permitted Investments designated
by the Trustee), which are required to be deposited in the Certificate Account
by the Servicer, may be invested in Permitted Investments on the Business Day on
which they were received. The foregoing requirements for remittance by the
Servicer and deposit by the Servicer into the Certificate Account shall be
exclusive. 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.

     (g) Each institution that maintains the Collection Account or the
Certificate Account shall 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 related Servicer Remittance Date (except
that if such Permitted Investment is an obligation of the institution that
maintains such Collection Account or is otherwise immediately available, then
such Permitted Investment shall mature not later than the Servicer Remittance
Date) and (ii) in the case of the Certificate Account, the Business Day
immediately preceding the first Distribution Date that follows the date of such
investment (except that if such Permitted Investment is an obligation of the
institution that maintains such Certificate Account or a fund for which such
institution serves as custodian 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 Servicer or the Trustee,
as applicable, 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

                                       83

<PAGE>

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.

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

     To the extent required by a related first lien 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 "nonsufficient funds" or other denial by the 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.

     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

                                       84

<PAGE>

     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 for Advances and Servicing Advances (to
     the extent such Servicing Advances 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)
     occurring after the Cut-off Date 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, Condemnation Proceeds, Insurance Proceeds or Liquidation
     Proceeds) that represent late recoveries of payments of principal and/or
     interest on such particular Mortgage Loan(s) in respect of which any such
     Advance was made;

          (iii) to reimburse the Servicer for any Non-Recoverable Advance
     previously made and, to the extent that such Non-Recoverable Servicing
     Advances 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, any Non-Recoverable Servicing Advance;

          (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) to pay to the
     Servicer any unpaid Servicing Fees and to reimburse it for any unreimbursed
     Servicing Advances, the Servicer's right to reimbursement of Servicing
     Advances pursuant to this subclause (vi) 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 Mortgage Loan) that represent late recoveries of the payments
     for which such advances were made pursuant to Section 3.01 or Section 3.06;

          (vii) to pay to 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;

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

          (ix) to reimburse the Servicer or the Depositor for expenses incurred
     by either of them in connection with the Mortgage Loans or the Certificates
     and reimbursable pursuant to Section 3.25 or Section 6.03 hereof;

          (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 if 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;

                                       85

<PAGE>

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

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

          (xiii) to reimburse itself for Advances or Servicing Advances from
     amounts in the Collection Account held for future distributions that were
     not included in Available Funds for the preceding Distribution Date. An
     amount equal to the amount withdrawn from the Collection Account pursuant
     to this subclause (xiv) shall be deposited in the Collection Account by the
     Servicer on the next succeeding Distribution Date that funds are to be
     distributed to Certificateholders.

     In addition, no later than 2:30 p.m. Eastern Time on the Servicer
Remittance Date, the Servicer shall cause to be withdrawn from the Collection
Account 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), to the extent on deposit, and such amount shall be
deposited in the Certificate Account.

     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 (viii) above.

     In the event of any failure by the Servicer to remit to the Trustee for
deposit into the Certificate Account any amounts (including any Advance)
required to be so remitted by the Servicer on the Servicer Remittance Date, the
Servicer shall pay to the Trustee, for its own account, interest on such amounts
at the "prime rate" (as specified in the New York edition of the Wall Street
Journal) until such failure is remedied.

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

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

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

          (iii) to reimburse the Trustee for expenses incurred by the Trustee
     and reimbursable pursuant to Section 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.

                                       86

     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 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.

     (a) Except as otherwise provided in this Section 3.11(a), when any property
subject to a Mortgage has been or is about to be conveyed by the Mortgagor, the
Servicer shall to the extent that it has knowledge of such conveyance or
prospective conveyance, enforce any due-on-sale clause contained in

                                       87

<PAGE>

any Mortgage Note or Mortgage, but only to the extent that such enforcement will
not adversely affect or jeopardize coverage under any Required Insurance Policy;
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, and need not exercise any such right, if consistent with
applicable mortgage servicing practices, the Servicer reasonably believes that
collection and other recoveries in respect of such Mortgage Loans would be
maximized if the Mortgage Loans were not accelerated. If the Servicer reasonably
believes that the due-on-sale clause is not enforceable under applicable law, an
Opinion of Counsel, which shall be reimbursable as a Servicing Advance to the
extent provided in Section 3.08(a)(ii) hereof, delivered to the Trustee and the
Depositor to the foregoing shall conclusively establish the reasonableness of
such belief, but which shall not be required. In addition to the foregoing, the
Servicer shall not be required to enforce any "due-on-sale" clause if in the
reasonable judgment of the Servicer, entering into an assumption and
modification agreement with a Person to whom such property shall be conveyed and
releasing the original Mortgagor from liability would be in the best interest of
the Certificateholders. In the event that the Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Servicer is authorized, subject to Section 3.11(b), to
take or enter into an assumption and modification agreement from or 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, the Mortgagor remains liable thereon, provided that the
Mortgage Loan shall continue to be covered (if so covered before the Servicer
enters such agreement) by the applicable Required Insurance Policies. The
Servicer, subject to Section 3.11(b), is also authorized with the prior approval
of the insurers under any Required Insurance Policies 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 Mortgage Note. Notwithstanding the
foregoing, the Servicer shall not be deemed to be in default under this Section
3.11(a) by reason of any transfer or assumption that the Servicer reasonably
believes it is restricted by law from preventing.

     (b) Subject to the Servicer's duty to enforce any due-on-sale clause to the
extent set forth in Section 3.11(a) hereof, in any case in which a Mortgaged
Property has been conveyed to a Person by a Mortgagor, and such Person is to
enter into an assumption agreement or modification agreement or supplement to
the Mortgage Note or Mortgage that requires the signature of the Trustee, or if
an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and
deliver or cause to be prepared and delivered to the Trustee for signature and
shall direct, in writing, the Trustee to execute the assumption agreement with
the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
(including, but not limited to, the Mortgage Rate, the amount of the Scheduled
Payment, the Maximum Rate, the Minimum Rate, the Gross Margin, the Periodic Rate
Cap, the Adjustment Date, any prepayment charge and any other term affecting the
amount or timing of payment on the Mortgage Loan) may be changed. The Servicer
shall notify the Trustee that any such substitution or assumption agreement has
been completed by forwarding to the Trustee the original of such substitution or
assumption agreement, which in the case of the original shall be added to the
related Mortgage File and 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. Any fee collected by the Servicer for entering into
an assumption or substitution of liability agreement will be retained by the
Servicer as additional servicing compensation.

                                       88

<PAGE>

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

     (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 as a
Non-Recoverable Servicing Advance, as contemplated in Section 3.08 hereof. If
the Servicer has received written notice that a Mortgaged Property that the
Servicer is contemplating acquiring in foreclosure or by deed-in-lieu of
foreclosure is located within a one-mile radius of any site with environmental
or hazardous waste risks known to the Servicer, the Servicer will, prior to
acquiring the Mortgaged Property, consider such risks and only take action in
accordance with Accepted Servicing Practices.

     With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee or its nominee (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 may receive usual and customary real
estate referral fees for real estate brokers in connection with the listing and
disposition of REO Property. The Servicer shall prepare a statement with respect
to each REO Property that has been rented showing the aggregate rental income
received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Servicer to comply with the reporting requirements of the REMIC Provisions. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Collection Account no later than the close of business on each Determination
Date. The Servicer shall perform the tax reporting and withholding related to
foreclosures, abandonments and cancellation of indebtedness income as specified
by Sections 1445, 6050J and 6050P of the Code by preparing and filing such tax
and information returns, as may be required.

     In the event that the Issuing Entity acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
the expiration of three years from the end of the year of its acquisition by the
Issuing Entity or, at the expense of the Issuing Entity, obtain 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

                                       89

<PAGE>

by the Issuing Entity of such Mortgaged Property subsequent to such three-year
period 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 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) 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

                                       90

<PAGE>

     (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)(vi) 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 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)(vi) 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) The Servicer, in its sole discretion, shall have the right to elect (by
written notice in the form of an Officer's Certificate sent to the Trustee,
which Officer's Certificate shall (i) set forth the affected Mortgage Loan or
REO Property and the Purchase Price, (ii) certify that the Purchase Price has
been deposited into the Collection Account and (iii) confirm that the purchase
complies in all respect with this Section 3.12(c)) to purchase for its own
account from the Issuing Entity any Mortgage Loan that is ninety-one (91) days
or more Delinquent or REO Property for which the Servicer has accepted a
deed-in-lieu of foreclosure at a price equal to the Purchase Price. The Purchase
Price for any Mortgage Loan or REO Property purchased hereunder shall thereafter
be delivered to the Trustee for deposit in the Certificate Account and the
Trustee, upon receipt of such deposit and a Request for Release from the
Depositor in the form of Exhibit I hereto, shall release or cause to be released
to the Servicer the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the Servicer, in each case
without recourse, representation or warranty, as shall be necessary to vest in
the Servicer any Mortgage Loan or REO Property released pursuant hereto and the
Servicer shall succeed to all the Trustee's right, title and interest in and to
such Mortgage Loan and all security and documents related thereto. Such
assignment shall be an assignment outright and not for security. The Servicer
shall thereupon own such Mortgage Loan or REO Property, and all security and
documents, free of any further obligation to the Trustee or the
Certificateholders with respect thereto. The Servicer shall not use any
procedure in selecting Mortgage Loans to be repurchased that is materially
adverse to the interests of the Certificateholders.

     In the event that the Servicer is acting as the servicer and the Servicer
(or an Affiliate of the Servicer) is the owner of more than 50% of the Class of
Certificates which is then currently in a first loss position and such party is
deemed to be the "Primary Beneficiary" as defined in FIN 46R, the provisions of
the preceding paragraph shall not apply and the Servicer (or an Affiliate of the
Servicer), in its sole discretion, shall have the right to elect (by written
notice in the form of an Officer's Certificate sent to the Trustee, which
Officer's Certificate shall (i) set forth the affected Mortgage Loan or REO
Property and the Purchase Price, (ii) certify that the Purchase Price has been
deposited into the Collection Account and (iii) confirm that the purchase
complies in all respect with this Section 3.12(c)) to purchase for its own
account from the Issuing Entity any Mortgage Loan that is 120 days or more
Delinquent or REO Property for which the Servicer has accepted a deed-in-lieu of
foreclosure, during the period commencing on the first day of the calendar
quarter succeeding the calendar quarter in which the Initial Delinquency Date
(as defined below) occurred with respect to such Mortgage Loan and ending on the
last Business Day of such calendar quarter. If the Servicer (or an Affiliate of
the Servicer) does not exercise its purchase right with respect to a Mortgage
Loan during the period specified in the preceding sentence, such Mortgage Loan
shall thereafter again become eligible for purchase pursuant to the preceding
sentence only after the Mortgage Loan ceases to be 120 days or more Delinquent
and thereafter becomes 120 days Delinquent again. The "Initial Delinquency Date"
of a Mortgage Loan shall mean the date on which the Mortgage Loan first became
120 days Delinquent. Prior to repurchase pursuant to this Section 3.12(c), the
Servicer shall be required to continue to make monthly advances pursuant to
Section 4.01. The Servicer shall not use any procedure in selecting Mortgage
Loans to be repurchased which is materially adverse to the interests of the
Certificateholders. The Servicer shall purchase any Mortgage Loan or REO
Property pursuant to this paragraph at a price equal to the Purchase Price. The
Purchase Price for any Mortgage Loan or REO Property purchased hereunder shall
be delivered to the Trustee for deposit in the Certificate Account and the
Trustee, upon receipt of such deposit and a Request for Release from the
Depositor in the form of Exhibit I hereto, shall release or cause to be released
to the Servicer the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the Servicer, in each case
without recourse, representation or warranty, as shall be necessary to vest in
the Servicer any Mortgage Loan or REO Property released pursuant hereto and the
Servicer shall succeed to all the Trustee's right, title and interest in and to
such Mortgage Loan and all security and documents related thereto. The
provisions in this paragraph shall only apply if Wilshire Credit Corporation is
the servicer.

     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 designee by delivering a Request for Release substantially in the form of
Exhibit I. Upon receipt of such request, the Trustee or its designee shall
promptly release the related Mortgage File to the Servicer, and the Trustee or
its designee shall at the Servicer's written direction execute and deliver to
the Servicer the request for reconveyance, deed of reconveyance or release or
satisfaction of mortgage or such instrument releasing the lien of the Mortgage
in each case provided by the Servicer, 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 such purpose, 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 designee
shall, upon delivery to the Trustee or its designee of a Request for Release in
the form of Exhibit I signed by a Servicing Officer, release the Mortgage File
to the Servicer. 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 designee 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 designee
(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 designee shall mutually agree. The Trustee or
its designee shall make reasonable efforts to release the related Mortgage
File(s) within three (3) Business Days of receipt of a properly completed
Request for Release pursuant to clauses (i), (ii) or (iii) above and shall so
release within four (4) Business Days. Receipt of a properly completed Request
for Release (including any Request for Release delivered in an electronic format
pursuant to (iii) above) shall be authorization to the Trustee or its designee
to release such Mortgage Files, provided the Trustee or its designee 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 designee complies with its duties and obligations under the agreement. If
the Trustee or its designee is unable to release the Mortgage Files within the
period previously specified, the Trustee or its designee shall immediately
notify the Servicer indicating the reason for such delay. If the Servicer is
required to pay penalties or damages due to the Trustee or its designee's
negligent failure to release the related Mortgage File or the Trustee or its
designee's negligent failure to execute and release documents within four (4)
Business Days after its receipt of a Request for Release, the Trustee or its
designee, shall be liable for such penalties or damages directly caused by it
and shall have no liability for penalties or damages attributable to the
Servicer's actions or inactions.

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

     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
shall deliver or cause to be delivered to the Trustee or its designee, for
signature, as appropriate, any court pleadings, requests for trustee's sale or
other documents necessary to effectuate such foreclosure or any legal action
brought to obtain judgment

                                       93

<PAGE>

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 or its designee to be returned to the Trustee promptly after possession
thereof shall have been released by the Trustee or its designee 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 or its designee 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 or its designee an Officer's Certificate of a
Servicing Officer certifying as to the name and address of the Person to which
the Mortgage File or the documents therein were delivered and the purpose or
purposes of such delivery.

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

     All Mortgage Files and funds collected or held by, or under the control of,
the Servicer in respect of any Mortgage Loans, whether from the collection of
principal and interest payments or from Liquidation Proceeds, including but not
limited to, any funds on deposit in the Collection Account, shall be held by the
Servicer for and on behalf of the Trustee and shall be and remain the sole and
exclusive property of the Trustee, 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 or
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,
Prepayment Interest Excess, late payment fees, 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 similar fees payable
by the Mortgagor, all income and gain net of any losses realized from Permitted
Investments in the Collection Account, and other benefits arising from the
Collection Account or Escrow Account shall be retained by the Servicer to the
extent not required to be deposited in the Collection Account pursuant to
Section 3.05 or 3.12(a) hereof or the Escrow Account pursuant to Section 3.06
hereof. The Servicer shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder (including payment of any
premiums for hazard insurance, as required by Section 3.10 hereof and
maintenance of the other forms of insurance coverage required by Section 3.10
hereof) and shall not be entitled to reimbursement therefor except as
specifically provided in Sections 3.08 and 3.12 hereof.

                                       94

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

     SECTION 3.17. Annual Statement as to Compliance.

     Not later than (a) March 12 of each calendar year (other than the calendar
year during which the Closing Date occurs) or (b) with respect to any calendar

without unreasonable effort or expense and within such timeframe as may be
reasonably requested. Any such supplementation or modification shall be made in
accordance with Section 10.01 without the consent of the Certificateholders, and
may result in a change in the reports filed by the Trustee on behalf of the
Issuing Entity under the Exchange Act.

     SECTION 3.19. Subordination 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 default with
respect to such Mortgage Loan is imminent or (ii) such subordination and
participation in such governmental program will not result in a change in
payment expectations with respect to such Mortgage Loan. For purposes of the
preceding sentence, a change in payment expectations occurs if, as a result of
such subordination and participation in such governmental program, (1) there is
a substantial enhancement of the Mortgagor's capacity to meet the payment
obligations under the Mortgage Loan and that capacity was primarily speculative
prior to such subordination and participation in such governmental program and
is adequate after such subordination and participation in such governmental
program or (2) there is a substantial impairment of the Mortgagor's capacity to
meet the payment obligations under the Mortgage Loan and that capacity was
adequate prior to such subordination and participation in such governmental
program and is primarily speculative after such subordination and participation
in such governmental program. The preceding sentence and clause (ii) of the
second preceding sentence are intended to comply with Treasury Regulations
Section 1.1001-3(e)(4) and shall be interpreted in accordance therewith.

     SECTION 3.20. Periodic Filings.

     As set forth on Schedule V 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 second Business Day after the occurrence of an event requiring
disclosure on Form 8-K (a "reportable event"), the Depositor, the Sponsor or the
Servicer, as applicable, shall have (i) 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) and (ii) delivered to the
Trustee all information, data, and exhibits required to be provided or filed
with such Form 8-K in an EDGAR-compatible format agreed upon by the Trustee and
Depositor, Sponsor or Servicer. In the event that the reportable event does not
pertain to the Servicer, at the time such notice is provided to the Trustee, 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. After preparing the Form 8-K on behalf of the
Depositor, the Trustee shall forward electronically a draft copy of the Form 8-K
to the Depositor and the Servicer for review. No later than the end of business
on the second Business Day 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 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 within two (2) Business Days; provided that the
Depositor has notified the Trustee in writing 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 a Form 8-K with the
Commission, the Trustee will 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

                                       98

<PAGE>

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 or signatures 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.

     The Depositor shall notify the Trustee of its intent to provide Additional
Form 10-D Disclosure prior to the related Distribution Date. As set forth in
Schedule W 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, will
forward to the Trustee in EDGAR-compatible form (with a copy to the Servicer),
or in such other form as otherwise agreed upon by the Trustee and the Depositor,
the form and substance of the Additional Form 10-D Disclosure by the fifth (5th)
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 ninth (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 written 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 (2) 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, assuming that the information
provided to the Trustee by the Servicer is correct, 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 Section. 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 (1) with
respect to any failure to properly prepare, execute or file such Form 10-D
resulting from the Trustee's inability or failure to obtain or receive any
information needed to prepare, arrange for execution or file such Form 10-D on a
timely basis and (2) with respect to the date of filing so long as filing occurs
by the Commission's deadline.

     Prior to March 30, 2007 (and, if applicable, prior to the ninetieth (90th)
calendar day after the end of the fiscal year for the Issuing Entity), the
Trustee shall, on behalf of the Issuing Entity and in accordance with industry
standards, prepare and file with the Commission via EDGAR a Form 10-K with
respect to the Issuing Entity. Such Form 10-K shall include the following items,
in each case to the extent

                                       99

<PAGE>

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 notified the
Trustee that it 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 as set forth on the
Reporting Servicer's report on Assessment of Compliance 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 certification (the
"Sarbanes-Oxley Certification") in the form attached hereto as Exhibit S,
executed by the senior officer in charge of securitizations of the Servicer. In
addition to (i) through (iv) above, any 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 X hereto, no later than March 12 (other than the
Trustee, who shall not be required to deliver any information until March 15) of
each year that the Issuing Entity is subject to the Exchange Act reporting
requirements, commencing in 2007, (i) certain parties to the transaction shall
be required to provide to the Depositor and the Servicer, to the extent known,
any Additional Form 10-K Disclosure, if applicable, and (ii) the Depositor
shall, to the extent it deems necessary, forward to the Trustee in
EDGAR-compatible form, or in such other form as otherwise agreed upon by the
Trustee and the Depositor, the form and substance of the Additional Form 10-K
Disclosure by March 15. The Depositor will be responsible for any reasonable
fees and expenses incurred by the Trustee in connection with including any
Additional Form 10-K Disclosure on Form 10-K pursuant to this paragraph.

     After preparing the Form 10-K, the Trustee shall forward electronically a
draft copy of the Form 10-K to the Depositor and the Servicer for review. Upon
the request of the Servicer, the Depositor shall confirm that it has reviewed
the Form 10-K, that it has been properly prepared and that the Servicer may rely
on the accuracy thereof (other than with respect to any portion of the Form 10-K
or 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 third Business Day following receipt of a final copy of the Form
10-K, and if requested, the above described confirmation from the Depositor, a
senior officer of the Servicer shall sign the Form 10-K and return an electronic
or fax copy of such signed Form 10-K (with an original executed hard copy to
follow by overnight mail) to the Trustee, and the Trustee shall file such Form
10-K by March 30. 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 this Section. 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 (1) 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 or signatures needed to prepare, arrange for execution or file such
Form 10-K on a timely basis and (2) with respect to the date of filing so long
as the filing occurs by the Commission's deadline.

                                      100

<PAGE>

     Each Form 10-K shall include a Sarbanes-Oxley Certification in the form
attached hereto as Exhibit S. 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 an Officer's Certificate (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 Issuing Entity, file a Form 12B-25
and one or more amended Form 10-Ks, to the extent such amendments are accepted
pursuant to the Exchange Act, to include such missing information or exhibits
promptly after receipt thereof by the Trustee.

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

     The Servicer agrees to furnish to the Trustee promptly, from time to time
upon request of the Depositor, such further information, reports, and financial
statements within its control related to this Agreement and the Mortgage Loans
as is reasonably necessary to prepare and file all necessary reports with the
Commission. The Trustee shall have no responsibility to file any items with the
Commission other than those specified in this Section 3.20, and the Servicer
shall execute any and all Form 8-Ks, Form 10-Ds and Form 10-Ks required
hereunder.

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

     In the event that the Trustee is unable to timely file with the Commission
all or any required portion of any Form 8-K, Form 10-D or Form 10-K required to
be filed pursuant to this Agreement because required disclosure information was
either not delivered to it or delivered to it after the delivery deadlines set
forth in this Agreement, the Trustee will immediately notify the Depositor and
the Servicer. In the case of Form 10-D and 10-K, the Depositor, Servicer and
Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a Form
10-DA and Form 10-KA, as applicable, pursuant to Rule 12b-25 of the Exchange
Act. In the case of Form 8-K, the Trustee will, upon receipt of all disclosure
information required to be included on Form 8-K, include such disclosure
information on the next Form 10-D. In the event that any previously filed Form
8-K, Form 10-D or Form 10-K needs to be amended, the party to this Agreement
deciding that an amendment to such Form 8-K, Form 10-D or Form 10-K is required
will notify the Depositor, the Trustee and the Servicer and such parties will
cooperate to

                                      101

<PAGE>

prepare any necessary Form 8-KA, Form 10-DA or Form 10-KA. Any Form 15, Form
12b-25 or any amendment to Form 8-K, Form 10-D or Form 10-K shall be signed by
an officer of the Servicer. Each party acknowledges that the performance by any
party of its duties under this Section 3.20 related to the timely preparation
and filing of Form 15, a Form 12b-25 or any amendment to Form 8-K, Form 10-D or
Form 10-K is contingent upon the other parties observing all applicable
deadlines (and the related grace periods thereto) in the performance of their
duties under this Section 3.20 and Sections 3.17 and 3.18. No party shall have
liability for any loss, expense, damage, claim arising out of or with respect to
any failure to properly prepare and/or timely file any such Form 15, Form 12b-25
or any amendments to Forms 8-K, Form 10-D or Form 10-K, where such failure
results from another party's inability or failure to obtain or receive, on a
timely basis, any information from any party hereto needed to prepare, arrange
for execution or file such Form 15, Form 12b-25 or any amendments to Forms 8-K,
Form 10-D or Form 10-K, not resulting from its own negligence, bad faith or
willful misconduct.

     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 3.17, 3.18 (other than Section
3.18(f)) 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 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 of Compliance provided on its
behalf pursuant to Section 3.17 or 3.18, as applicable, 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. Failure by the Trustee to
deliver an Accountant's Attestation when required under Section 3.18(f) will be
grounds for immediate removal of the Trustee under Section 8.08; in the event of
such failure, the Trustee shall pay certain costs and expenses of the Depositor
caused by such failure as separately agreed to by the Depositor and the Trustee.

     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 the Servicer to deliver 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 of
Compliance provided on its behalf pursuant to Section 3.17 or 3.18, as
applicable (to the extent the Servicer is responsible for providing information
or calculating amounts included in such information), or the negligence, bad
faith or willful misconduct of the Servicer in connection therewith. If the

                                      102

<PAGE>

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
by the Trustee or the Depositor in connection with the 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.

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

          (i)   loan number;

          (ii)  current Mortgage Rate;

          (iii) current principal balance;

          (iv)  original principal balance;

          (v)   prepayment charge amount due;

          (vi)  prepayment charge amount collected; and

          (vii) reason why full prepayment charge amount was not collected, if
                applicable.

     SECTION 3.24. Statements to Trustee. Not later than the Servicer Remittance
Date, the Servicer shall furnish to the Trustee an electronic file providing
loan level accounting data for the period ending on the last Business Day of the
preceding month in the format mutually agreed upon between the Servicer and the
Trustee, including but not limited to information described in Section 4.05(a).

     SECTION 3.25. Further Indemnification by the Servicer.

     The Servicer shall indemnify the Sponsor, the Issuing Entity, Trustee (in
its individual capacity and in its capacity as Trustee) and the Depositor 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 breach of representations of the Servicer or willful
misfeasance, bad faith or negligence, or by reason of reckless disregard of
obligations and duties hereunder. The Servicer promptly shall notify the
Sponsor, the Trustee and the Depositor or any other relevant party if a claim is
made by a third party with respect to such party and this Agreement or the
Mortgage Loans and, if subject to this indemnification obligation, assume (with
the 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

                                      103

<PAGE>

Servicer shall provide the Trustee and the Depositor with a written report of
all expenses and advances incurred by the Servicer pursuant to this Section
3.25, and the Servicer from the assets of the Trust Fund in the Collection
Account promptly shall reimburse itself for all amounts advanced by it pursuant
to the second sentence of this Section 3.25 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. Existing Servicing Agreement.

     The Servicer acknowledges the transfer on the Closing Date of the servicing
of the Mortgage Loans from the Existing Servicing Agreement to this Agreement
pursuant to the Existing Servicing Agreement.

     SECTION 3.28. 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 and the
Trustee, and if the Servicer so notifies such parties, the Servicer may cease
its initiation of collection efforts thereon; 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 90-day period from the date of the notice in the manner
described in Section 2.05.

     SECTION 3.29. Rights of the NIMs Insurer.

     Each of the rights of the NIMs Insurer set forth in this agreement shall
exist so long as the NIM Notes issued pursuant to the Indenture remain
outstanding 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.

     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.
Each such Advance shall be remitted to the Collection Account no later than 2:30
p.m. New York City time on the Servicer Remittance Date in immediately available
funds. The Servicer shall be obligated to make any such Advance only to the
extent that such advance would not be a Non-Recoverable Advance. If the Servicer
shall have determined that it has made a Non-Recoverable Advance or that a
proposed Advance or a lesser portion of such Advance would constitute a
Non-Recoverable Advance, the Servicer shall deliver (i) to the

                                      104

<PAGE>

Trustee for the benefit of the Certificateholders funds constituting the
remaining portion of such Advance, if applicable, and (ii) to the Depositor,
each Rating Agency, 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 for a first lien Mortgage 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 such Mortgage
Loan is paid in full or 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.

     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 resulting from a Principal Prepayment in full, 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 with respect to any
Distribution Date shall be limited to the product of (x) one-twelfth of 0.25%
per annum and (y) the aggregate Stated Principal Balance of the Mortgage Loans.
In case of such deposit, the Servicer shall not be entitled to any recovery or
reimbursement from the Depositor, the Trustee, the Issuing Entity or the
Certificateholders. With respect to any Distribution Date, to the extent that
the Prepayment Interest Shortfall exceeds Compensating Interest (such excess, a
"Non-Supported Interest Shortfall"), such Non-Supported Interest Shortfall shall
reduce the Current Interest with respect to each Class of Certificates, pro rata
based upon the amount of interest each such Class would otherwise be entitled to
receive on such Distribution Date. Notwithstanding the foregoing, there shall be
no reduction of the Servicing Fee in connection with Prepayment Interest
Shortfalls related to the Relief Act and the Servicer shall not be obligated to
pay Compensating Interest with respect to Prepayment Interest Shortfalls related
to the Relief Act or bankruptcy proceedings.

Distribution Date in accordance with the provisions of Section 4.04.

     SECTION 4.04. Distributions.

Funds received on the Group One Mortgage Loans will be deemed to be distributed

distributions are available to be applied, if necessary, to the Class or Classes
of Certificates that are not related to such group of Mortgage Loans.

     (c) All amounts representing prepayment charges in respect of the Mortgage
Loans, and amounts paid by the Servicer in respect of prepayment charges
pursuant to this Agreement will be distributed by the Trustee to the Holders of
the Class P Certificates pursuant to Section 4.04(b).

     (d) On each Distribution Date (or in the case of any Net Swap Payments owed

prior to such Distribution Date), the Trustee shall make the following
distributions from the Certificate Account of an amount equal to the Principal

               reduced to zero, and second, to the Class A-1 Certificates until
               the Certificate Principal Balance of the Class A-1 Certificates
               has been reduced to zero;

               (2) the Group Two Principal Distribution Amount shall be
               distributed sequentially as follows: to the Class A-2A

<PAGE>

               Principal Balance thereof has been reduced to zero, then to the

               zero; provided, however, that on and after the Distribution Date
               on which the aggregate Certificate Principal Balance of the
               Subordinate Certificates and the Class C Certificates has been
               reduced to zero, any principal distributions allocated to the

distributions up to the following amounts from the Certificate Account of the
remainders pursuant to Section 4.04(b)(xiv) and 4.04(d)(xiii) hereof, and each
such distribution shall be made only after all distributions pursuant to
Sections 4.04(b) and (d) above shall have been made until such remainders shall
have been fully distributed for such Distribution Date:

          (i) to the Class A and Class R Certificates, any amounts due as

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

          All distributions or allocations made with respect to
Certificateholders within each Class on each Distribution Date shall be
allocated among the outstanding Certificates in such Class equally in proportion
to their respective Initial Certificate Principal Balances (or Percentage
Interests).

     (j) The Trustee is hereby directed by the Depositor to execute the Corridor
Contracts on behalf of the Issuing Entity in the forms 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 Trustee under the Corridor Contracts
at closing shall be paid by the Depositor. Notwithstanding anything to the
contrary contained herein or in the Corridor Contracts, the Trustee shall not be
required to make any payments to the Cap Contract Counterparty under the
Corridor Contracts. Any payments received under the terms of the related
Corridor Contract will be available to pay the holders of the related Classes of
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 and Class R 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

                                       110

<PAGE>

Class C Certificates. Payments in respect of such Floating Rate Certificate
Carryovers from proceeds of the Corridor Contracts shall be paid to the related
Classes of Certificates, pro rata based upon such Floating Rate Certificate
Carryovers for each such Class of Offered Certificates. Amounts received on the
Class A-1 Corridor Contract will only be available to make payments on the Class
A-1 Certificates, amounts received on the Class A-2 Corridor Contract will only
be available to make payments on the Class A-2 Certificates, amounts received on
the Subordinate Certificate Corridor Contract will only be available to make
payments on the Subordinate 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 any 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 Classes of Certificates as provided in this
     Section 4.04(j). 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 applicable Corridor Contract will
     equal the product of (i) the excess of (x) One-Month Cap 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 applicable Corridor Contract),
     over (y) the rate with respect to such Distribution Date as shown under the
     heading "1ML Lower Collar" in the schedule to the applicable Corridor
     Contract, (ii) an amount equal to the lesser of (A) the related Corridor
     Contract Notional Balance for such Distribution Date as shown in the
     schedule to the applicable Corridor Contract and (B) the Certificate
     Principal Balance of (I) in the case of the Class A-1 Corridor Contract,
     the Class A-1 and Class R Certificates, (II) in the case of the Class A-2
     Corridor Contract, the Class A-2 Certificates and (III) in the case of the
     Subordinate Certificate Corridor Contract, the Subordinate 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, the Trustee shall, on the monthly
     statement to Certificateholders described in Section 4.05 below, report the
     amounts paid with respect to Floating Rate Certificate Carryovers and the
     amount due to the holders of the Class C Certificates.

          (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
     its respective 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 Business Days, as defined in
     the applicable Corridor Contract, after notice of such failure is received
     by the Cap Contract Counterparty) to make a payment due under the
     applicable 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 applicable
     Corridor Contract, the termination of the Trust Fund and the applicable
     Corridor Contract becoming illegal or subject to certain kinds of taxation.

          (iv) On the Closing Date, the Cap Contract 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 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.

                                       111

<PAGE>

               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,
     when required, establish a Corridor Posted Collateral Account on behalf of
     the holders of the Offered Certificates on the Closing Date.

               The Cap Contract Counterparty shall remit any Posted Collateral
     to the Trustee to the extent required under the Corridor Contracts, and the
     Trustee shall, upon receipt of the Posted Collateral, deposit the Posted
     Collateral into the Corridor Posted Collateral Account and shall hold such
     amounts 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 may be
     required to make payments from the Corridor Posted Collateral Account to
     the Cap Contract Counterparty. 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.

     (k) In accordance with this Agreement, the Servicer shall prepare and
deliver a report (the "Remittance Report") to the Trustee in the form of a
computer readable magnetic tape (or by such other means as the Servicer and the
Trustee may agree from time to time) containing such data and information such
as to permit the Trustee to prepare the Monthly Statement to Certificateholders
and make the required distributions for the related Distribution Date.

     (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 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 contain the Swap Account, which
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 Interest Trust to 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, indemnities
and protections of the Trustee hereunder.

          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 April 2012, the Supplemental Interest Trust Trustee shall, based on the
Significance Estimate (which shall be provided in writing to the Trustee by the
Depositor within five (5) Business Days prior to the Distribution Date),
calculate the Significance Percentage of the Swap Agreement. If on any such
Distribution Date,

                                       112

<PAGE>

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 April 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 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 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) April 25, 2012.

prior to such Distribution Date), any Swap Termination Payments or Net Swap
Payments owed to the Swap Counterparty will be paid out of, or any Net Swap
Payments or Swap Termination Payments received from the Swap Counterparty will
be deposited into, the Swap Account. 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;

     than a Defaulted Swap Termination Payment, if any, owed to the Swap
     Counterparty;

          (iii) to each class of the Class A and Class R 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 M-1 Certificates, the Class M-2
     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the

     extent unpaid;

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

          (viii) to the Class A, Class R, Class M and Class B Certificates, 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).

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
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.

          On the Closing Date, the Cap Contract 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 Corridor Contracts, which annex is intended to protect the
Supplemental Interest Trust 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 Swap
Agreement. In connection with the foregoing, the Supplemental Interest Trust
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 Supplemental Interest Trust Trustee under the Corridor
Contracts, the Supplemental Interest Trust 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 Supplemental Interest Trust such as finding a replacement cap
contract counterparty or a guarantor that meets established criteria of the
Rating Agencies, the Supplemental Interest Trust Trustee shall make payments
from the Corridor Posted Collateral Account to the Cap Contract Counterparty in
accordance with the provisions of the Corridor Contracts. 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.

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.

     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

                                       120

provided. Upon surrender for registration of Transfer of any Certificate, the
Authenticating Agent shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

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

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

     (b) 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 the 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 forms 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 addressed to the Trustee 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.

     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

                                       121

<PAGE>

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 may
be made unless the Trustee has received (I) a representation that the transferee
is not an employee benefit plan or other arrangement 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") (collectively,
"Plan"), or is directly or indirectly acquiring the ERISA Restricted Certificate
or Class R Certificate for, on behalf of, or with any assets of any such Plan,
or (II) solely with respect to ERISA Restricted Certificates, (A) if the
Certificate has been the subject of an ERISA-Qualifying Underwriting, a
representation 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 Section I and III of PTCE 95-60, or (B) solely in the case of any such
Certificate that is a Definitive Certificate, an Opinion of Counsel satisfactory
to the Trustee and the Depositor, 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 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 Definitive Certificates, the representations set
forth in the immediately two preceding paragraphs of this Subsection 5.02(b),
other than clause (II)(B) in the immediately preceding paragraph, shall be
deemed to have been made to the Trustee by the transferee's acceptance of a
Certificate (or the acceptance by a Certificate Owner of the beneficial interest
in any Class of Certificate). Notwithstanding any other provision herein to the
contrary, any purported transfer of a Certificate to or on behalf of a Plan
without the delivery to the Trustee of a representation or an Opinion of Counsel
satisfactory to the Trustee as described above shall be void and of no effect.
The Trustee shall not be under any liability to any Person for any registration
of transfer of any Certificate that is in fact not permitted by this Section
5.02(b) 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(b) 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.

     (c) 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 no Transfer
     of any Class R Certificate shall be registered unless, in addition to the
     certificates

                                       122

<PAGE>

     required to be delivered to the Trustee under subparagraph (b) 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(c)(ii) shall not have been satisfied unless the Transfer
     Affidavit includes such other form of declaration.

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

          (iv) Any attempted or purported Transfer of any Ownership Interest in
     a Class R Certificate in violation of the provisions of this Section
     5.02(c) 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(c), 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(b) and this
     Section 5.02(c) 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 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 addressed to the
     Trustee (at the expense of the Holder of the Class R Certificate) 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(b) and (c) will apply to each such separate
     certificate as if the separate certificate

                                       123

<PAGE>

     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 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(c) 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 addressed to the Trustee,
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 addressed to and
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.

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

     (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 the Trustee to save
the Trustee 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) 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.

                                       124

<PAGE>

     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 on behalf of the
Depositor. 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.

                                       125

<PAGE>

     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.

     SECTION 5.07. Notices to Depository.

     Whenever any notice or other communication is required to be given to
Certificateholders of the Class with respect to which Book-Entry Certificates
have been issued, unless and until Definitive Certificates shall have been
issued to the related Certificate Owners and 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 Depositor is unable to locate a qualified successor, (b)
the Depositor, at its sole option, advises the Trustee that it elects to
terminate the book-entry system with respect to such Certificates through the
Depository 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,
through the Depository, 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
office at 60 Livingston Avenue, Mail Code EP-MN-WS3D, St. Paul, Minnesota
55107-2292, Attention: Structured Finance/SURF 2007-BC2, 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.

                                       126

<PAGE>

     SECTION 5.10. Authenticating Agents.

     (a) One or more Authenticating Agents (each, an "Authenticating Agent") may
be appointed hereunder each of which shall be authorized to act on behalf of the
Trustee in authenticating the Certificates. Wherever reference is made in this
Agreement to the authentication of Certificates by the Trustee's certificate of
authentication, such reference shall be deemed to include authentication on
behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent must be an entity organized and doing business under
the laws of the United States of America or any state thereof, having a combined
capital and surplus of at least $15,000,000, authorized under such laws to
operate a trust business and subject to supervision or examination by federal or
state authorities. If the Authenticating Agent is a party other than the
Trustee, the Trustee shall have no liability in connection with the performance
or failure of performance of the Authenticating Agent. U.S. 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, U.S. 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, and is
hereby authorized to, 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.
The initial Authenticating Agent shall have all of the rights, indemnities and
protections of the Trustee hereunder.

                                   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

                                       127

<PAGE>

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 Servicer may be merged or
consolidated, or any Person resulting from any merger or consolidation to which
the Depositor or Servicer shall be a party, or any Person succeeding to the
business of the Depositor or Servicer, shall be the successor of the Depositor
or 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 a 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 or 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, 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, 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 may, in its discretion, 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 interests of the Servicer 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.

     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

                                       128

<PAGE>

determination permitting the resignation of the Servicer shall be evidenced by
an Opinion of Counsel to such effect delivered to the Trustee and the NIMs
Insurer. No such resignation shall become effective until the Trustee or a
successor servicer reasonably acceptable to the NIMs Insurer and the Trustee is
appointed and has assumed the Servicer's responsibilities, duties, liabilities
and obligations hereunder. Any such resignation shall not relieve the Servicer
of any of the obligations specified in Sections 7.01, 7.02 and 7.03 as
obligations that survive the resignation or termination of the Servicer.

     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, for the benefit of certain lenders, and (ii) provided that no
Event of Default exists, 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, the Trustee shall appoint the
Servicing Rights Pledgee or its designee as successor servicer but only if such
successor servicer meets the requirements of a successor servicer under this
Agreement and 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 and bond shall, together, meet the requirements of
Fannie Mae or Freddie Mac, unless the Servicer has obtained a waiver of such
requirements from the Sponsor. The Servicer shall provide the Trustee, upon
request with 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
commercial 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. The Servicer shall ensure that any such policy or fidelity
bond shall by its terms not be cancelable without thirty (30) days' prior
written notice to the Trustee.

                                   ARTICLE VII
                        DEFAULT; TERMINATION OF SERVICER

     SECTION 7.01. Events of Default.

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

          (i) any failure by the Servicer to 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

                                       129

<PAGE>

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

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

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

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

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

     If an Event of Default shall occur with respect to the Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, or solely with respect to
clause (i) above by 5:00 p.m. on the Servicer Remittance Date, the Trustee may,
or at the direction of the NIMs Insurer or the Holders of Certificates
evidencing not less than 50% of the Voting Rights evidenced by the Certificates
(with the written consent of the NIMs Insurer, 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 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, subject to and in accordance with Section 6.04 hereof, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in the
Trustee as successor servicer. To the extent the Event of Default resulted from
the failure of the Servicer to make a required Advance, the Trustee, in its
capacity as successor servicer, 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 of the occurrence of an Event of Default or an event
that, with notice, passage of time, other action or any combination of the

                                       130

<PAGE>

foregoing would be an Event of Default, such notice to be provided in any event
within two Business Days of such occurrence.

     Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a Scheduled Payment on a Mortgage Loan that was due prior to the notice
terminating the Servicer's rights and obligations as Servicer hereunder and
received after such notice, that portion thereof to which the Servicer would
have been entitled pursuant to Sections 3.08(a)(i) through (viii), 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. [RESERVED]

     SECTION 7.03. 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, as
applicable, the Trustee shall be entitled to all 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 the appointment of which successor shall be approved by
the NIMs Insurer 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 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

                                       131

<PAGE>

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.

     In the event that the Servicer shall for any reason no longer be the
Servicer hereunder (including by reason of any Event of Default),
notwithstanding anything to the contrary above, the Trustee and the Depositor
hereby agree that within ten (10) Business Days or 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, the Servicing Rights
Pledgee or its designee shall be appointed as successor servicer (provided that
at the time of such appointment the Servicing Rights Pledgee or such designee
meets the requirements of a successor servicer set forth above) and the
Servicing Rights Pledgee agrees to be subject to the terms of this Agreement.

     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 7.04. 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 and
to each Rating Agency.

     (b) Within sixty (60) days after the occurrence of any Event of Default,
the Trustee shall transmit by mail to all Certificateholders 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 Trustee.

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

                                       132

<PAGE>

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 conform to the
requirements of this Agreement, 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 be liable, individually or as Trustee, 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 NIMs Insurer or the
     Holders of each Class of Certificates evidencing not less than 50% of the
     Voting Rights of such Class 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) except as otherwise expressly provided in this Agreement, if any
     default occurs in the making of a payment due under any Permitted
     Investment, or if a default occurs in any other performance required under
     any Permitted Investment, the Trustee may and, subject to Section 8.01 and
     Section 8.02, upon the request of the Holders of the Certificates
     representing more than 50% of the Voting Rights allocated to any Class of
     Certificates, shall take such action as may be appropriate to enforce such
     payment or performance, including the institution and prosecution of
     appropriate proceedings.

     The Trustee shall have no duty hereunder with respect to any complaint,
claim, demand, notice or other document it may receive or which may be alleged
to have been delivered to or served upon it by the parties as a consequence of
the assignment of any Mortgage Loan hereunder; provided, however, that the
Trustee shall promptly remit to the Servicer upon receipt any such complaint,
claim, demand, notice or

                                       133

<PAGE>

other document (i) which is delivered to the Trustee, (ii) of which a
Responsible Officer has actual knowledge and (iii) which contains information
sufficient to permit the Trustee to make a determination that the real property
to which such document related to is a Mortgaged Property.

     SECTION 8.02. Certain Matters Affecting the Trustee.

     (a) Except as otherwise provided in Section 8.01:

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

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

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

          (iv) prior to the occurrence of an Event of Default hereunder and
     after the curing of all Events of Default that may have occurred, the
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,
     opinion, report, notice, 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 50%
     of the Voting Rights of such Class;

          (v) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents,
     accountants or attorneys;

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

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

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

          (ix) the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Agreement or to make any
     investigation of matters arising hereunder or to institute, conduct or
     defend any litigation hereunder or in relation hereto at the request, order
     or direction of any of the NIMs Insurer or the Certificateholders, pursuant
     to the provisions of this Agreement, unless the NIMs Insurer or such
     Certificateholders shall have offered to the Trustee

                                       134

<PAGE>

     reasonable security or indemnity against the costs, expenses and
     liabilities that may be incurred therein or thereby; and

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

     (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee without
the possession of any of the Certificates, or the production thereof at the
trial or other proceeding relating thereto, and any such suit, action or
proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

     (c) [Reserved]

     SECTION 8.03. Trustee Not Liable for 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 representations as to
the validity or sufficiency of this Agreement, of any Mortgage Loan or related
document other than with respect to the Trustee's execution and authentication
of 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 Certificate Account by the Depositor or the
Servicer.

     SECTION 8.04. Trustee May Own Certificates.

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

     SECTION 8.05. Trustee's Fees.

     The Trustee shall be entitled to earnings on or investment income with
respect to funds in or credited to the Certificate Account.

     SECTION 8.06. Indemnification of Trustee; Expenses.

     (a) The Trustee and its respective directors, officers, employees and
agents shall be entitled to indemnification from the Issuing Entity for any
loss, liability or expense incurred in connection with any legal proceeding or
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 or in connection with 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:

                                       135

<PAGE>

          (i) with respect to any such claim, the Trustee shall have given the
     Depositor and the Holders 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
     cooperate and consult fully 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; and

          (iv) any such loss, liability or expense to be indemnified by the
     Issuing Entity must constitute an "unanticipated expense" of the Issuing
     Entity within the meaning of Treasury Regulations Section
     1.860G-1(b)(3)(ii).

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

     (b) The Trustee shall be entitled to all reasonable expenses, disbursements
and advancements 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
advancements 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 $300,000, excluding any Servicing Transfer Costs and any
auction expenses incurred by the Trustee in connection with Section 9.01(a)(i),
in the aggregate in any calendar year; provided, however, that such cap shall
apply only if NIM Notes have been issued, are outstanding 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. Any amounts not in excess of this cap
may be withdrawn by the Trustee from the Certificate Account at any time.

     (d) The Trustee shall be further indemnified by the Issuing Entity for and
held harmless against, any loss, liability or expense arising out of, or in
connection with, the provisions set forth in the last paragraph of Section 2.01
hereof, including, without limitation, all costs, liabilities and expenses
(including reasonably legal fees and expenses) of investigating and defending
itself against any claim, action or proceeding, pending or threatened, relating
to the provisions of such paragraph.

     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

                                       136

<PAGE>

such reduction). If such corporation or association publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 8.07 the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 8.07, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.08 hereof. The corporation or national banking association serving as
Trustee may have normal banking and trust relationships with the Depositor, the
NIMs Insurer and their Affiliates; provided, however, that such corporation
cannot be an Affiliate of the Servicer other than the Trustee in its role as
successor to 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 and 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 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, (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, or
(iii)(A) a tax is imposed with respect to the Issuing Entity by any state in
which the Trustee or the Issuing Entity is located, (B) the imposition of such
tax would be avoided by the appointment of a different trustee and (C) the
Trustee fails to indemnify the Issuing Entity against such tax, 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, one copy of which shall be delivered to the Servicer
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, or the NIMs Insurer upon
failure of the Trustee to perform its obligations hereunder, 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 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.

                                       137

<PAGE>

     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 and the Servicer an instrument accepting such
appointment hereunder and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein.

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

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

     SECTION 8.10. Merger or Consolidation of Trustee.

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

     SECTION 8.11. Appointment of Co-Trustee or Separate Trustee.

     Notwithstanding any other provisions of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing any Mortgage Note may at the time be
located, the Servicer and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee 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 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 at the request of the Trustee; provided that
the appointment of a co-trustee has been appointed with due care. 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.

                                       138

<PAGE>

     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, except for the obligation of the Trustee under this
     Agreement to advance funds on behalf of the Servicer, 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.

     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
Servicer, 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

                                       139

<PAGE>

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 tax
law, including without limitation, the calculation of any original issue
discount using the Prepayment Assumption; (e) provide information necessary for
the computation of tax imposed on the transfer of a Class R Certificate to a
Person that is not a Permitted Transferee, or an agent (including a broker,
nominee or other middleman) of a Person that is not a Permitted Transferee, or a
pass-through entity in which a Person that is not a Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct the affairs of each of the REMICs
and grantor trusts provided for herein at all times that any Certificates are
outstanding so as to maintain the status of each of the REMICs provided for
herein as a REMIC under the REMIC Provisions and the status of each of the
grantor trusts provided for herein as a grantor trust under Subpart E, Part I of
Subchapter J of the Code; (g) not knowingly or intentionally take any action or
omit to take any action that would cause the termination of the REMIC status of
any of the REMICs provided for herein or result in the imposition of tax upon
any such REMIC; (h) not knowingly or intentionally take any action or omit to
take any action that would cause the termination of the grantor trust status
under Subpart E, Part I of Subchapter J of the Code of any of the grantor trusts
provided for herein or result in the imposition of tax upon any such grantor
trust; (i) pay, from the sources specified in the last paragraph of this Section
8.12(a), the amount of any federal, state and local taxes, including prohibited
transaction taxes as described below, imposed on each of the REMICs provided for
herein prior to the termination of the Trust Fund when and as the same shall be
due and payable (but such obligation shall not prevent the Trustee or any other
appropriate Person from contesting any such tax in appropriate proceedings and
shall not prevent the Trustee from withholding payment of such tax, if permitted
by law, pending the outcome of such proceedings); (j) sign or cause to be signed
federal, state or local income tax or information returns; (k) maintain records
relating to each of the REMICs and grantor trusts 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 the fair market value and
adjusted basis of the Trust Fund property determined at such intervals as may be
required by the Code, as may be necessary to prepare the foregoing returns,
schedules, statements or information; and (l) as and when necessary and
appropriate, represent each of the REMICs and grantor trusts 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

                                       140

<PAGE>

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

     In the event that any tax is imposed on "prohibited transactions" of any of
the REMICs provided for herein as defined in Section 860F(a)(2) of the Code, on
the "net income from foreclosure property" of any of such REMICs as defined in
Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Trustee, if any such other tax arises out of or results from a breach by
the Trustee of any of its obligations under this Agreement or as a result of the
location of the Trustee, (ii) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or as a result of the
location of such other party or (iii) in all other cases, or in the event that
any liable party here fails to honor its obligations under the preceding clauses
(i) or (ii), any such tax will be paid first with amounts (other than amounts
derived by the Issuing Entity from a payment on any 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
B-3 Certificates (pro rata), third, to the Class B-2 Certificates (pro rata),
fourth, to the Class B-1 Certificates (pro rata), fifth, to the Class M-6
Certificates (pro rata), sixth, to the Class M-5 Certificates (pro rata),
seventh, to the Class M-4 Certificates (pro rata), eighth, to the Class M-3
Certificates (pro rata), ninth, to the Class M-2 Certificates (pro rata), tenth,
to the Class M-1 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 earliest of (i) the successful completion of the
auction referred to in Section 9.01(b), (ii) the exercise by the Servicer of the

                                       141

<PAGE>

Clean Up Call on any Distribution Date on or after the Clean Up Call Date and
(iii) the later of (x) 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 (y) 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) (i) Any termination pursuant to Section 9.01(a)(i) shall be effected by
the auction by the Trustee of all of the Mortgage Loans and REO Properties via a
solicitation of bids in accordance with the auction procedures set forth in
Exhibit N. The Trustee shall accept the highest such bid, provided that such bid
equals or exceeds the amount described in the definition of "Auction Termination
Price." Any sale pursuant to such auction process must occur no earlier than the
second day of the calendar month that includes the Distribution Date on which
the proceeds of such sale will be distributed to the Certificateholders.

          (ii) If no sale under Section 9.01(a)(i) occurs, 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 Clean Up
Call Price. If a sale under Section 9.01(a)(1) does not occur as a result of the
Auction's failure to achieve the Auction Termination Price and the NIMS Insurer
fails to exercise its option to purchase all of the Mortgage Loans, the Servicer
may, on any Distribution Date following such Auction, at its option, terminate
the Trust Fund by purchasing all of the Mortgage Loans and REO Properties at a
price equal to the Clean Up Call Price.

     Notwithstanding anything to the contrary herein, the Auction Termination
Amount received by the Trustee upon the completion of a successful auction or
the Clean Up Call Price paid by the Servicer shall be deposited by the Trustee
directly into the Certificate Account promptly upon receipt of such amount by
the Trustee. Any Clean Up Call Price to be paid by the Servicer shall be paid by
the Servicer to the Trustee for deposit into the Certificate Account.
Notwithstanding anything herein to the contrary, only an amount equal to the
Auction Termination Price or the Clean Up Call Price, reduced in each case by
the portion thereof consisting of any Swap Termination Payment (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.

     (c) If the Trustee receives a bid meeting the conditions specified in
Section 9.01(b)(i) or there is a Clean Up Call pursuant to Section 9.01(b)(ii),
then the Trustee's written acceptance of such bid shall constitute a plan of
complete liquidation within the meaning of Section 860F of the Code, and the
Trustee shall release to the winning bidder of the auction or the Servicer
pursuant to the Clean Up Call, upon the Trustee's receipt of the Auction
Termination Price or the Clean Up Call Price and the distribution by the Trustee
of such amounts in accordance with Section 4.04 hereof, the Mortgage Files
pertaining to the Mortgage Loans being purchased and take such other actions as
the winning bidder or such purchaser may reasonably request to effect the
transfer of the Mortgage Loans to the winning bidder or such purchaser.

     In connection with any such purchase pursuant to the preceding paragraph,
the Servicer shall remit to the Trustee for deposit in the Certificate Account
all amounts then on deposit in the Collection Account (less amounts permitted to
be withdrawn by the Servicer pursuant to Section 3.08), which deposit shall be
deemed to have occurred immediately preceding such purchase.

                                       142

<PAGE>

     Any purchase shall be accomplished by deposit into the Certificate Account
of the Auction Termination Amount paid by the winning bidder if an Auction
Termination has occurred or the Clean Up Call Price in the event the Servicer
exercises a Clean Up Call and only following the delivery of an Opinion of
Counsel in form and substance acceptable to the Trustee that such termination is
a "Qualified Liquidation" under Section 860F of the Code.

     (d) The right of the Depositor to direct the Trustee to effect an Auction
Termination or of the Servicer to effect a Clean Up Call pursuant to clause
(a)(i) or (a)(ii) above shall be conditioned upon the aggregate Stated Principal
Balance of the Mortgage Loans, at the time of any such repurchase, aggregating
ten percent (10%) or less of the Stated Principal Balance of the Mortgage Loans
as of the Cut-off Date.

     (e) In the event that the Trustee is unable to complete a sale at the
Auction Termination, the Servicer may terminate the Trust Fund by purchasing all
the Mortgage Loans, and REO Properties at a price equal to the Clean Up Call
Price on any Distribution Date on or after the Clean Up Call Date, by exercising
a Clean Up Call.

     (f) Notwithstanding anything to the contrary in this Article IX, no Auction
Termination or Clean Up Call shall be effected at any time during which NIM
Notes are outstanding if the Class C Certificateholder notifies the Trustee in
writing that the Class C Certificateholder does not consent to such proposed
Auction Termination or Clean Up Call. The parties hereto intend that the portion
of any amount received upon an Auction Termination or Clean Up Call that is
attributable to clause (D) of the definition of Auction Termination Price or
clause (d) of the definition of Clean Up Call Price and required to cover what
would otherwise be a shortfall in the amounts described in clause (D) of the
definition of Auction Termination Price or clause (d) of the definition of Clean
Up Call Price shall be treated for federal income tax purposes as having been
paid by the winning bidder of the auction or the Servicer, as applicable,
directly to the Class C Certificateholder (rather than having been paid to any
REMIC) to induce the Class C Certificateholder to consent to the Auction
Termination or Clean Up Call, as applicable.

     (g) 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)).

     (h) 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.

     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
within seven (7) Business Days 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. If the Trustee is able to terminate the Trust Fund
pursuant to Section 9.01(a)(i), or if the Servicer conducts a Clean Up Call and
terminates the Trust Fund pursuant to Section 9.01(a)(ii) or 9.01(e), at least
ten (10) days prior to the date notice is to be mailed to the affected
Certificateholders, the Trustee shall notify the Depositor and the Servicer of
the date such electing party intends to terminate the Trust Fund and of the
applicable repurchase price of the Mortgage Loans and REO Properties.

     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 not earlier than the 10th day and no
later than the 15th day of the month immediately preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date upon
which final distribution on the Certificates will be made upon presentation and
surrender of Certificates at the office therein designated, (b) the location of
the office or agency at which such presentation and surrender must be made, and
(c) that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Certificates at the office therein specified. The Trustee will give such notice
to each Rating Agency at the time such notice is given to Certificateholders.

     In the event such notice is given, the Servicer shall cause all funds in
the Collection Account to be deposited in the Certificate Account on the
Business Day prior to the applicable Distribution Date in an amount equal to the
final distribution in respect of the Certificates. Upon such final deposit with
respect to the Trust Fund and the receipt by the Trustee of a Request for
Release therefor, the Trustee shall promptly release to the Trustee 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 Certificateholder
shall be entitled to all unclaimed funds and other assets of the Trust Fund that
remain subject hereto. Upon payment to the Class R Certificateholder of such
funds and assets, the Trustee shall have no further duties or obligations with
respect thereto.

     SECTION 9.03. Additional Termination Requirements.

     (a) In the event the Trustee is able to effect an Auction Termination or
the Servicer conducts a Clean Up Call 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
addressed to the Trustee, at the expense of the Servicer 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, which 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
     Issuing Entity;

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

          (iii) At the time of the making of the final payment on the
     Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Class R Certificateholder all cash on hand
     (other than cash retained to meet outstanding claims known to the Trustee),
     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 Certificateholder.

     (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 a
plan of complete liquidation prepared and delivered to it by the Depositor upon
the written request of the Depositor, and the receipt of Opinion of Counsel
referred to in Section 9.03(a)(i) 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 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, 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
Depositor shall notify the Servicer in writing to transfer the assets of the
Trust Fund as of the termination

                                       145

<PAGE>

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 Depositor shall notify the
Servicer of the person to whom the assets should be transferred on that date. In
the latter event the Servicer shall be entitled to recover its servicing fee and
any advances made for the interim servicing period from the collections on the
assets which have been purchased from the Trust and the new owner of the assets,
and the agreements for the new owner to obtain ownership of the assets of the
Trust Fund shall so provide.

                                    ARTICLE X
                            MISCELLANEOUS PROVISIONS

     SECTION 10.01. Amendment.

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

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

          (ii) To correct, modify or supplement any provision herein which may
     be inconsistent with 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 addressed to the Trustee 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 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 addressed to the Trustee, which opinion shall be
an expense of the party requesting such amendment but in any case shall not be
an expense of the Trustee, the Trust Fund 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.

                                       146

<PAGE>

     This Agreement may also be amended from time to time by the Depositor, 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.

     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 addressed to the Trustee, 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 Trust Fund, to the effect that such amendment
is permitted hereunder and 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 or upon the written request of
the Trustee to the Servicer, the Servicer shall furnish written notification of
the substance of such amendment to each Certificateholder, each Rating Agency,
the Cap Contract Counterparty and the Swap Counterparty.

     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. Such consent
need only be obtained from Certificateholders of classes adversely affected by
the proposed amendment. 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 conditions precedent for amending this
Agreement have been complied with.

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

     Notwithstanding the foregoing, the Trustee shall not enter into any
amendment to this Agreement that would have a materially adverse effect on the
Swap Counterparty or the Cap Contract Counterparty without first obtaining the
consent of the Swap Counterparty or the Cap Contract Counterparty, respectively.

     SECTION 10.02. Counterparts.

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

     SECTION 10.03. Governing Law.

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

     SECTION 10.04. Intention of Parties.

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

     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 Swap Counterparty, the Cap Contract Counterparty and each
Rating Agency with respect to each of the following of which a Responsible
Officer of the Trustee has written notice or 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 or the
     Collection Account.

                                       148

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

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.

     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.

     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

                                       149

<PAGE>

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 such reasonable indemnity 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, subject to a reasonable confidentiality
agreement, 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; 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. [RESERVED]

     SECTION 10.12. Additional Rights of the NIMs Insurer

     Each party to this Agreement, 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, statement, filing, information,
data or other communication 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

                                       150

<PAGE>

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.

     Wherever in this Agreement there shall be a requirement that there be no
downgrade, reduction, withdrawal or qualification of or other effect on the
rating of any Class of Certificates by any Rating Agency as of any date, there
also shall be deemed to be a requirement that there be no such effect on any
Class of notes issued pursuant to the Indenture and guaranteed by the NIMs
Insurer as of such date. In addition, 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.

     SECTION 10.13. 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 the Swap Counterparty,
respectively, so long as any of the Corridor Contracts or the Swap Agreement, as
applicable, remains in effect.

     SECTION 10.14. Assignment; Sales; Advance Facilities.

     (a) The Servicer is hereby authorized to enter into a financing or other
facility (any such arrangement, an "Advance Facility"), the documentation for
which complies with Section 10.14(e) below, under which (1) the Servicer assigns
or pledges its rights under this Agreement to be reimbursed for any or all
Advances and/or Servicing Advances to (i) a Person, which may be a
special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing Person agrees to fund all the Advances and/or Servicing Advances
required to be made by the Servicer pursuant to this Agreement. No consent of
the Trustee, Certificateholders or any other party shall be required before the
Servicer may enter into an Advance Facility nor shall the Trustee or the
Certificateholders be a third party beneficiary of any obligation of an Advance
Financing Person to the Servicer. Notwithstanding the existence of any Advance
Facility under which an Advance Financing Person agrees to fund Advances and/or
Servicing Advances, (A) the Servicer (i) shall remain obligated pursuant to this
Agreement to make Advances and/or Servicing Advances pursuant to and as required
by this Agreement and (ii) shall not be relieved of such obligations by virtue
of such Advance Facility and (B) neither the Advance Financing Person nor any
Servicer's Assignee (as hereinafter defined) shall have any right to proceed
against or otherwise contact any Mortgagor for the purpose of collecting any
payment that may be due with respect to any related Mortgage Loan or enforcing
any covenant of such Mortgagor under the related Mortgage Loan documents.

     (b) If the Servicer enters into an Advance Facility, the Servicer and the
related Advance Financing Person shall deliver to the Trustee at the address set
forth in Section 10.05 hereof a written

                                       151

<PAGE>

notice (an "Advance Facility Notice"), stating (a) the identity of the Advance
Financing Person and (b) the identity of the Person (the "Servicer's Assignee")
that will, subject to Section 10.14(c) hereof, have the right to make
withdrawals from the Collection Account pursuant to Section 3.08(a) hereof to
reimburse previously unreimbursed Advances and/or Servicing Advances ("Advance
Reimbursement Amounts"). Advance Reimbursement Amounts (i) shall consist solely
of amounts in respect of Advances and/or Servicing Advances for which the
Servicer would be permitted to reimburse itself in accordance with Section 3.08
hereof, assuming the Servicer had made the related Advance(s) and/or Servicing
Advance(s) and (ii) shall not consist of amounts payable to a successor servicer
in accordance with Section 3.05 hereof to the extent permitted under Section
10.14(e) below.

     (c) Notwithstanding the existence of an Advance Facility, the Servicer, on
behalf of the Advance Financing Person and the Servicer's Assignee, shall be
entitled to receive reimbursements of Advances and/or Servicing Advances in
accordance with Section 4.01 hereof, which entitlement may be terminated by the
Advance Financing Person pursuant to a written notice to the Trustee in the
manner set forth in Section 10.05 hereof. Upon receipt of such written notice,
the Servicer shall no longer be entitled to receive reimbursement for any
Advance Reimbursement Amounts and the Servicer's Assignee shall immediately have
the right to receive from the Collection Account all Advance Reimbursement
Amounts. Notwithstanding the foregoing, and for the avoidance of doubt, (i) the
Servicer and/or the Servicer's Assignee shall only be entitled to reimbursement
of Advance Reimbursement Amounts hereunder from withdrawals from the Collection
Account pursuant to Section 4.01 of this Agreement and shall not otherwise be
entitled to make withdrawals or receive amounts that shall be deposited in the
Distribution Account pursuant to Section 4.01 hereof, and (ii) none of the
Trustee or the Certificateholders shall have any right to, or otherwise be
entitled to, receive any Advance Reimbursement Amounts to which the Servicer or
Servicer's Assignee, as applicable, shall be entitled pursuant to Section 4.01
hereof. An Advance Facility may be terminated by the joint written direction of
the Servicer and the related Advance Financing Person. Written notice of such
termination shall be delivered to the Trustee in the manner set forth in Section
10.05 hereof. None of the Depositor or the Trustee shall, as a result of the
existence of any Advance Facility, have any additional duty or liability with
respect to the calculation or payment of any Advance Reimbursement Amount, nor,
as a result of the existence of any Advance Facility, shall the Depositor or the
Trustee have any additional responsibility to track or monitor the
administration of the Advance Facility or the payment of Advance Reimbursement
Amounts to the Servicer's Assignee. The Servicer shall indemnify the Depositor,
the Trustee, any successor servicer and the Issuing Entity for any claim, loss,
liability or damage resulting from any claim by the related Advance Financing
Person, except to the extent that such claim, loss, liability or damage resulted
from or arose out of negligence, recklessness or willful misconduct on the part
of the Depositor, the Trustee or any successor servicer, as the case may be, or
failure by the successor servicer or the Trustee, as the case may be, to remit
funds as required by this Agreement or the commission of an act or omission to
act by the successor servicer or the Trustee, as the case may be, and the
passage of any applicable cure or grace period, such that an Event of Default
under this Agreement occurs or such entity is subject to termination for cause
under this Agreement. The Servicer shall maintain and provide to any successor
servicer and, upon request, the Trustee a detailed accounting on a loan-by-loan
basis as to amounts advanced by, pledged or assigned to, and reimbursed to any
Advance Financing 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.

     (d) [Reserved]

     (e) As between a predecessor Servicer and its Advance Financing Person, on
the one hand, and a successor servicer and its Advance Financing Person, if any,
on the other hand, Advance Reimbursement Amounts on a loan-by-loan basis with
respect to each Mortgage Loan as to which an Advance and/or Servicing Advance
shall have been made and be outstanding shall be allocated on a

                                       152

<PAGE>

"first-in, first out" basis. In the event the Servicer's Assignee shall have
received some or all of an Advance Reimbursement Amount related to Advances
and/or Servicing Advances that were made by a Person other than such predecessor
Servicer or its related Advance Financing Person in error, then such Servicer's
Assignee shall be required to remit any portion of such Advance Reimbursement
Amount to each Person entitled to such portion of such Advance Reimbursement
Amount. Without limiting the generality of the foregoing, the Servicer shall
remain entitled to be reimbursed by the Advance Financing Person for all
Advances and/or Servicing Advances funded by the Servicer to the extent the
related Advance Reimbursement Amounts have not been assigned or pledged to such
Advance Financing Person or Servicer's Assignee.

     (f) For purposes of any Officer's Certificate of the Servicer made pursuant
to Section 4.01, any Non-Recoverable Advance or Non-Recoverable Servicing
Advance referred to therein may have been made by such Servicer or any
predecessor Servicer. In making its determination that any Advance or Servicing
Advance theretofore made has become a Non-Recoverable Advance or Non-Recoverable
Servicing Advance, the Servicer shall apply the same criteria in making such
determination regardless of whether such Advance or Servicing Advance shall have
been made by the Servicer or any predecessor Servicer.

     (g) Any amendment to this Section 10.14 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 10.14, including amendments to
add provisions relating to a successor servicer, may be entered into by the
Trustee, the Depositor and the Servicer without the consent of any
Certificateholder, provided such amendment complies with Section 10.01 hereof.
All reasonable costs and expenses (including attorneys' fees) of each party
hereto of any such amendment shall be borne solely by the Servicer. The parties
hereto hereby acknowledge and agree that: (a) the Advances and/or Servicing
Advances financed by and/or pledged to an Advance Financing Person under any
Advance Facility are obligations owed to the Servicer payable only from the cash
flows and proceeds received under this Agreement for reimbursement of Advances
and/or Servicing Advances only to the extent provided herein, and the Trustee
and the Trust are not, as a result of the existence of any Advance Facility,
obligated or liable to repay any Advances and/or Servicing Advances financed by
the Advance Financing Person; (b) the Servicer will be responsible for remitting
to the Advance Financing Person the applicable amounts collected by it as
reimbursement for Advances and/or Servicing Advances funded by the Advance
Financing Person, subject to the provisions of 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 any Advance Financing
Person.

evidencing an ownership interest in distributions allocable to the Class A-[ ],
M-[ ], 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 A 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 Wilshire Credit Corporation (the "Servicer") and are
secured by first or second mortgages on Mortgaged Properties. The Trust Fund was
created pursuant to a pooling and servicing agreement (the "Agreement"), dated
as of April 1, 2007, between the Depositor, the Servicer and U.S. 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 Specialty Underwriting and Residential Finance Trust, Mortgage
Loan Asset-Backed Certificates, Series 2007-BC2, Class A-[ ], M-[ ], B-[ ] (the
"Class A-[ ], M-[ ], 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-1 Certificates, the Class A-2A Certificates, the Class A-2B
Certificates, the Class A-2C Certificates, the Class A-2D Certificates, the
Class M-1 Certificates, the Class M-2 Certificates, the Class M-3 Certificates,
the Class M-4 Certificates, the Class M-5 Certificates, the Class M-6
Certificates, the Class B-1 Certificates, the Class B-2 Certificates, the Class
B-3 Certificates, the Class P Certificates, the Class C Certificates, and the
Class R Certificate 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 May 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered at

                                      A-3

<PAGE>

the close of business on the last Business Day of the month preceding the month
in which such payment is made, if such last day is not a Business Day, the
Business Day immediately preceding such last day.

     Distributions on this Certificate will be made either by check mailed to
the address of the person entitled to distributions as it appears on the
Certificate Register or, in the case of any Certificateholder that has so
notified the Trustee in writing in accordance with the Agreement, 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; 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.

                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 SERIES 2007-BC2

     This Certificate is one of a duly authorized issue of Certificates,
designated as Specialty Underwriting and Residential Finance Trust Mortgage Loan
Asset-Backed Certificates, Series 2007-BC2, issued in one or more Classes of
Class A-1, Class A-2A, Class A-2B, Class A-2C, Class A-2D, Class M-1, Class M-2,
Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2, Class B-3,
Class P, Class C, and Class R 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

                                      A-6

<PAGE>

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.

     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 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.

                                 SERIES 2007-BC2

     This Certificate is one of a duly authorized issue of Certificates,
designated as Specialty Underwriting and Residential Finance Trust Mortgage Loan
Asset-Backed Certificates, Series 2007-BC2, issued in one or more Classes of
Class A-1, Class A-2A, Class A-2B, Class A-2C, Class A-2D, Class M-1, Class M-2,
Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2, Class B-3,
Class P, Class C, and Class R 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

                                      A-14

<PAGE>

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.

     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 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.

              SPECIALTY UNDERWRITING AND RESIDENTIAL FINANCE TRUST
                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 SERIES 2007-BC2

     This Certificate is one of a duly authorized issue of Certificates,
designated as Specialty Underwriting and Residential Finance Trust Mortgage Loan
Asset-Backed Certificates, Series 2007-BC2, issued in one or more Classes of
Class A-1, Class A-2A, Class A-2B, Class A-2C, Class A-2D, Class M-1, Class M-2,
Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2, Class B-3,
Class P, Class C, and Class R 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

                                      A-23

<PAGE>

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.

     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 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.

distribution on this Certificate will be made after due notice by the Trustee,

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

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 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

                                      A-30

<PAGE>

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.

     For federal income tax purposes, the Trust Fund will include multiple "real

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

Attention: Structured Finance/SURF 2007-BC2

Ladies and Gentlemen:

     We propose to purchase the Specialty Underwriting and Residential Finance
Trust, Mortgage Loan Asset-Backed Certificates, Series 2007-BC2, Class R
Certificate, described in the Prospectus Supplement, dated April 23, 2007, and
Prospectus, dated March 22, 2007.

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

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

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

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

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

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

     5. We certify that (i) we are a U.S. person or (ii) we will hold the Class
R Certificate in connection with the conduct of a trade or business within the
United States and have furnished the transferor and the Trustee with a duly
completed and effective Internal Revenue Service Form W-8ECI or successor form
at the time and in the manner required by the Code; for this purpose the term
"U.S. person" means a citizen or resident of the United States, a corporation,

adopted that provide otherwise) created or organized in or under the laws of the
United States, any State thereof or the District of Columbia, including an
entity treated as a corporation or partnership for federal income tax purposes,
an estate whose income is subject to United States federal income tax regardless
of the source of its income, or a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more such U.S. persons have the authority to control all substantial
decisions of the trust (or, to the extent provided in applicable Treasury
regulations, certain trusts in existence on August 20, 1996 which are eligible
to elect to be treated as U.S. Persons). We agree that any breach by us of this
certification shall render the transfer of any interest in the Class R
Certificate to us absolutely null and void and shall cause no rights in the
Class R Certificate to vest in us.

     6. We agree that in the event that at some future time we wish to transfer
any interest in the Class R Certificate, we will transfer such interest in the
Class R Certificate only (a) to a transferee that (i) is not a disqualified
organization and is not purchasing such interest in the Class R Certificate on
behalf of a disqualified organization, (ii) is a U.S. person or will hold the
Class R Certificate in connection with the conduct of a trade or business within

                                        Agreement

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

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

(2)  the Transferee's Employer Identification number is _____________________,

(3)  the Transferee is not a "disqualified organization" (as defined below), has

     acquiring any of its interest in the Specialty Underwriting and Residential
     Finance Trust, Mortgage Loan Asset-Backed Certificates, Series 2007-BC2,
     Class R Certificate on behalf of a disqualified organization or any other
     entity,

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

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

     Certificate as they become due,

(10) the Transferee consents to any amendment of the Pooling and Servicing

     Investors, Inc. (upon advice of counsel) to constitute a reasonable
     arrangement to ensure that the Class R Certificate will not be owned
     directly or indirectly by a disqualified organization, and

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

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

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

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

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

      (B) the Transferee is an eligible corporation as defined in Treasury
          regulations Section 1.860E-1(c)(6)(i) and has agreed in writing that
          any subsequent transfer of the Class R Certificate will be to another
          eligible corporation in a transaction that satisfies Treasury
          regulation Sections 1.860E-1(c)(4)(i), 1.860E-1(c)(4)(ii),
          1.860E-1(c)(4)(iii) and 1.860E1(c)(5) and such transfer will not be a
          direct or indirect transfer to a foreign permanent establishment
          (within the meaning of an applicable income tax treaty) of a domestic
          corporation.

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

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

     _____________________ (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

Transferor has conducted a reasonable investigation at the time of the transfer

                           FORM OF AUCTION PROCEDURES

     The following sets forth the auction procedures to be followed in
connection with Pooling and Servicing Agreement (the "Agreement") among Merrill
Lynch Mortgage Investors, Inc., U.S. Bank National Association as trustee and
Wilshire Credit Corporation, dated April 1, 2007. Capitalized terms used herein
that are not otherwise defined shall have the meanings described thereto in the
Agreement.

1.   Upon notice that the aggregate Stated Principal Balance of the Mortgage
     Loans is equal to ten percent (10%) or less of the Stated Principal Balance
     of the Mortgage Loans as of the Cut-off Date (which notice will also be
     sent to the Servicer), the Trustee will initiate the general auction
     procedures consisting of the following: (i) prepare a general solicitation
     package along with a confidentiality agreement; (ii) derive a list of
     bidders which shall include (x) the Holders of the Class C and Class P
     Certificates (other than the Sponsor or any Affiliate of the Sponsor) and
     (y) a minimum of three (3) bidders including the Holders of the Class C
     Certificates but not including the holders of the Class P Certificates,
     each of whom shall be a nationally recognized participant in mortgage
     finance; (iii) initiate contact with all bidders, (iv) send a
     confidentiality agreement to all bidders; and (v) upon receipt of a signed
     confidentiality agreement, send the general bid solicitation package to all
     bidders.

2.   The general solicitation package will include (i) the Agreement; (ii) a
     copy of all monthly trustee reports or electronic access thereto; (iii) a
     form of a Mortgage Loan Purchase Agreement acceptable to the Trustee, the
     Servicer and Depositor (the Mortgage Loans and other property included in
     the Trust Fund will be offered and sold on an "as is, where is" basis,
     without any representation or warranty, expressed or implied, of any kind
     and without recourse to, or guaranty by, the Trustee); (iv) a description
     of the minimum price as set forth in the Agreement; (v) a formal bid sheet
     as determined by the Depositor and accepted by the Trustee; (vi) a detailed
     timetable (which shall include, but not be limited to, the provisions and
     dates preliminary bids, due diligence and final bids); and (vii) a data
     tape of the Mortgage Loans as of the related Remittance Period reflecting
     substantially the same data attributes used in the Prospectus Supplement
     dated January 22, 2007.

3.   A detailed timetable will be determined approximately ten (10) days prior
     to each auction sale and shall be determined by the Depositor with the
     consent of the Trustee, which consent shall not be unreasonably withheld,
     within reasonable market conditions at the time of the auction sale.

4.   All bids will be submitted directly to the Trustee. Upon acceptance of a
     bid which meets or exceeds the conditions set forth in Section 9.01, the
     Trustee will complete the auction by selling the Mortgage Loans and the
     other property included in the Trust Fund and distribute the proceeds from
     the auction to the holders of the Certificates on the next succeeding
     Distribution Date as set forth in the Agreement. In the event the Trustee
     receives two (2) or more bids from bidders above the Auction Termination
     Price and at equal bids (a "Tie Event"), the Trustee shall notify such
     bidders to resubmit a bid to break the Tie Event.

5.   Upon determination that the minimum price was not met, the Trustee shall
     cancel such auction sale and notify the Servicer and Depositor immediately.

6.   The Trustee, the Servicer and the Depositor may mutually agree to revise or
     supplement these provisions as necessary, provided that the purchase price
     is at all times required to be at least the Auction Termination Price.

                                      O-3-8

<PAGE>

               (A) Section 6(e) of this Agreement will be amended by inserting
               on the first line "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 Firm
                    Offers from Reference Market-makers that are Eligible
                    Replacements. Each Firm Offer will be (1) for an amount that
                    would be paid to Counterparty (expressed as a negative
                    number) or by Counterparty (expressed as a positive number)
                    in consideration of an agreement between Counterparty 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 is to be included. The party making the
                    determination (or its agent) will request each Reference
                    Market-maker 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 obtained 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. The Market Quotation shall be
                    the Firm Offer actually accepted by Counterparty no later
                    than the Business Day preceding the Early Termination Date.
                    If no Firm Offers are provided by the Business Day preceding
                    the Early Termination Date, it will be deemed that the
                    Market Quotation in respect of such Terminated Transaction
                    or group of Transactions cannot be determined.

               (C) Counterparty shall use best efforts to accept a Firm Offer
               that would determine the Market Quotation. If more than one Firm
               Offer (which, if accepted, would determine the Market Quotation)
               is provided, Counterparty shall accept the Firm Offer (among such
               Firm Offers) which would require either (x) the lowest payment by
               the Counterparty to the Reference Market-maker, to the extent
               Counterparty would be required to make a payment to the Reference
               Market-maker or (y) the highest payment from the Reference
               Market-maker to Counterparty, to the extent the Reference
               Market-maker would be required to make a payment to the
               Counterparty. If only one Firm Offer (which, if accepted, would
               determine the Market Quotation) is provided, Counterparty shall
               accept such Firm Offer.

               (D) Upon the written request by Counterparty to Bear Stearns,
               Bear Stearns shall obtain the Market Quotations on behalf of
               Counterparty.

               (E) If the Settlement Amount is a negative number, Section
               6(e)(i)(3) of this Agreement 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) Counterparty shall
                    pay to Bear Stearns an amount equal to the absolute value of
                    the Settlement Amount in respect of the Terminated
                    Transactions, (II) Counterparty shall pay to Bear Stearns
                    the

                                      O-3-9

<PAGE>

               Termination Currency Equivalent of the Unpaid Amounts owing to
               Counterparty; 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 Bear Stearns under the
               immediately preceding clause (III) shall not be netted-off
               against any amount payable by Counterparty under the immediately
               preceding clause (I)."

(n)  "TERMINATION CURRENCY" means United States Dollars.

(o)  ADDITIONAL TERMINATION EVENTS. Additional Termination Events will apply:

     (i)  If, upon the occurrence of a Swap Disclosure Event (as defined in Part
          5(l)(ii) below) Bear Stearns has not, within ten (10) calendar days
          after such Swap Disclosure Event complied with any of the provisions
          set forth in Part 5 (l) below, then an Additional Termination Event
          shall have occurred with respect to Bear Stearns, Bear Stearns shall
          be the sole Affected Party and all Transactions hereunder shall be
          Affected Transaction.

     (ii) If, without the prior written consent of Bear Stearns where such
          consent is required under the Pooling and Servicing Agreement, an
          amendment or supplemental agreement is made to the Pooling and
          Servicing Agreement which amendment or supplemental agreement could
          reasonably be expected to have a material adverse effect on the
          interests of Bear Stearns under this Agreement, an Additional
          Termination Event shall have occurred with respect to Counterparty,
          Counterparty shall be the sole Affected Party and all Transactions
          hereunder shall be Affected Transaction.

     (iii) (A) If a S&P First Level Downgrade has occurred and is
               continuing and Bear Stearns fails to take any action described
               under Part (5)(f)(i)(1), within the time period specified
               therein, then an Additional Termination Event shall have occurred
               with respect to Bear Stearns, Bear Stearns shall be the sole
               Affected Party with respect to such Additional Termination Event
               and all Transactions hereunder shall be Affected Transaction.

          (B)  If a S&P Second Level Downgrade has occurred and is continuing
               and Bear Stearns fails to take any action described under Part
               (5)(f)(i)(2) within the time period specified therein, then an
               Additional Termination Event shall have occurred with respect to
               Bear Stearns, Bear Stearns shall be the sole Affected Party with
               respect to such Additional Termination Event and all Transactions
               hereunder shall be Affected Transaction.

          (C)  If (A) a Moody's Second Level Downgrade has not occurred and been
               continuing for 30 or more Local Business Days and (B) Bear
               Stearns has failed to comply with or perform any obligation to be
               complied with or performed by Bear Stearns in accordance with the
               Credit Support Annex, then an Additional Termination Event shall
               have occurred with respect to Bear Stearns and Bear Stearns shall
               be the sole Affected Party with respect to such Additional
               Termination Event.

          (D)  If (A) a Moody's Second Level Downgrade has occurred and been
               continuing for 30 or more Local Business Days and (B) either (i)

               in respect of all of Bear Stearns' present and future obligations

Agreement and has at the time no future payment obligations, whether absolute or
contingent, under such Section, then unless Bear Stearns is required pursuant to
appropriate proceedings to return to the Counterparty or otherwise returns to
the Counterparty upon demand of the Counterparty any portion of any such

     payment (other than interest under Section 2(e), 6(d)(ii) or 6(e) of this
     Agreement) to be made by it to the other party under this Agreement. In
     making this representation, it may rely on:

          (1) the accuracy of any representations made by the other party

          other party does not deliver a form or document under Section
          4(a)(iii) of this Agreement by reason of material prejudice to its

<PAGE>

          relying on any communication (written or oral) of the other party as
          investment advice or as a recommendation to enter into this
          Transaction; it being understood that information and explanations

                    Transaction and is willing and able to accept those terms

the Corridor Account and the proceeds thereof, any claims against or obligations
of Counterparty under this Agreement or any other confirmation thereunder still
outstanding shall be extinguished and thereafter not revive. The Trustee shall
not have liability for any failure or delay in making a payment hereunder to
Bear Stearns due to any failure or delay in receiving amounts in the Corridor
Account from the Trust created pursuant to the Pooling and Servicing Agreement.

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

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

<PAGE>

     (i)  AMENDMENT OF PARAGRAPH 7 - EVENTS OF DEFAULT. Clause (iii) of
          Paragraph 7 shall not apply to Secured Party.

     (ii) NON-RELIANCE. Notwithstanding the obligations of the Secured Party
          under Paragraph 6(a), and without limiting the generality of the final
          sentence of Paragraph 6(a), each party, as Pledgor, acknowledges that
          it has the means to monitor all matters relating to all valuations,
          payments, defaults and rights with respect to Posted Collateral
          without the need to rely on the other party, in its capacity as
          Secured Party, and that, given the provisions of this Annex on
          substitution, responsibility for the preservation of the rights of the
          Pledgor with respect to all such matters is reasonably allocated
          hereby to the Pledgor.

          (iii) AGREEMENT AS TO SINGLE SECURED PARTY AND PLEDGOR. Each of
          Pledgor and Secured Party agree that, notwithstanding anything to the
          contrary in the recital to this Annex, Paragraph 1(b) or Paragraph 2
          or the definitions in Paragraph 12, (a) the term "Secured Party" as
          used in this Annex means only Secured Party, (b) the term "Pledgor" as

          Support hereunder.

          (iv)   TRUSTEE. The Trustee is hereby authorized to (i) make demands
                 on behalf of the Secured Party pursuant to Paragraph 3

                 all Posted Collateral in a segregated trust account.

          (vi)   EXTERNAL CALCULATIONS. At any time at which Pledgor (or, to the
                 extent applicable, its Credit Support Provider) does not have a
                 long-term unsubordinated and unsecured debt rating of at least
                 "BBB+" from S&P, the Valuation Agent shall (at its own expense)
                 obtain external calculations of the Secured Party's Exposure
                 from at least two Reference Market-makers on the last Local
                 Business Day of each calendar month. Any determination of the
                 S&P Collateral Amount shall be based on the greatest of the
                 Secured Party's Exposure determined by the Valuation Agent and
                 such Reference Market-makers. Such external calculation may not
                 be obtained from the same Reference Market-maker more than four
                 times in any 12-month period.

          (vii)  NOTICE TO S&P. At any time at which Pledgor (or, to the extent
                 applicable, its Credit Support Provider) does not have a
                 long-term unsubordinated and unsecured debt rating of at least
                 "BBB+" from S&P, the Valuation Agent shall provide to S&P not
                 later than the Notification Time on the Local Business Day
                 following each Valuation Date its calculations of the Secured
                 Party's Exposure and the Value of any Eligible Credit Support
                 or Posted Credit Support for that Valuation Date. The Valuation
                 Agent shall also provide to S&P any external marks of the
                 Secured Party's Exposure.

          (viii) EXPENSES. Pledgor shall be responsible for all reasonable costs
                 and expenses incurred by Secured Party in connection with the

               (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 Firm
                    Offers from Reference Market-makers that are Eligible
                    Replacements. Each Firm Offer will be (1) for an amount that
                    would be paid to Counterparty (expressed as a negative
                    number) or by Counterparty (expressed as a positive number)
                    in consideration of an agreement between Counterparty 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 is to be included. The party making the
                    determination (or its agent) will request each Reference
                    Market-maker 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 obtained 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. The Market Quotation shall be
                    the Firm Offer actually accepted by Counterparty no later
                    than the Business Day preceding the Early Termination Date.
                    If no Firm Offers are provided by the Business Day preceding
                    the Early Termination Date, it will be deemed that the
                    Market Quotation in respect of such Terminated Transaction
                    or group of Transactions cannot be determined.

               (C) Counterparty shall use best efforts to accept a Firm Offer
               that would determine the Market Quotation. If more than one Firm
               Offer (which, if accepted, would determine the Market Quotation)
               is provided, Counterparty shall accept the Firm Offer (among such
               Firm Offers) which would require either (x) the lowest payment by
               the Counterparty to the Reference Market-maker, to the extent
               Counterparty would be required to make a payment to the Reference
               Market-maker or (y) the highest payment from the Reference
               Market-maker to Counterparty, to the extent the Reference
               Market-maker would be required to make a payment to the
               Counterparty. If only one Firm Offer (which, if accepted, would
               determine the Market Quotation) is provided, Counterparty shall
               accept such Firm Offer.

               (D) Upon the written request by Counterparty to Bear Stearns,
               Bear Stearns shall obtain the Market Quotations on behalf of
               Counterparty.

               (E) If the Settlement Amount is a negative number, Section
               6(e)(i)(3) of the ISDA Master Agreement 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) Counterparty shall
                    pay to Bear Stearns an amount equal to the absolute value of
                    the Settlement Amount in respect of the Terminated
                    Transactions, (II) Counterparty shall pay to Bear Stearns
                    the Termination Currency Equivalent of the Unpaid Amounts
                    owing to Bear Stearns and (III) Bear Stearns shall pay to
                    Counterparty the Termination Currency Equivalent of the
                    Unpaid Amounts owing to Counterparty; 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 Bear Stearns under the immediately
                    preceding clause (III) shall not be netted-off against any
                    amount payable by Counterparty under the immediately
                    preceding clause (I)."

               calendar days after such Swap Disclosure Event complied with any
               of the provisions set forth in Part 5 (l) below, then an

                    Agreement, an amendment or supplemental agreement is made to
                    the Pooling and Servicing Agreement which amendment or
                    supplemental agreement could reasonably be expected to have
                    a material adverse effect on the interests of Bear Stearns

          has made its own independent decisions to enter into the Transaction
          and as to whether the Transaction is appropriate or proper for it
          based upon its own judgment and upon advice from such advisors as it
          has deemed necessary, (vi) it is not relying on any communication
          (written or oral) of the other party as investment advice or as a
          recommendation to enter into this Transaction; it being understood
          that information and

                                      U-1-12

<PAGE>

          explanations related to the terms and conditions of this Transaction
          shall not be considered investment advice or a recommendation to enter
          into this Transaction and (vii) it has not received from the other
          party any assurance or guaranty as to the expected results of this
          Transaction.

     (2)  Evaluation and Understanding.

               (i)  It has the capacity to evaluate (internally or through
                    independent professional advice) the Transaction and has
                    made its own decision to enter into the Transaction; and

               (ii) It understands the terms, conditions and risks of the
                    Transaction and is willing and able to accept those terms

Agreement to the contrary, the obligations of Counterparty hereunder are limited
recourse obligations of Counterparty, payable solely from the Swap Account and
the proceeds thereof, in accordance with the terms of the Pooling and Servicing
Agreement. In the event that the Swap Account and proceeds thereof should be
insufficient to satisfy all claims outstanding and following the realization of
the Swap Account and the proceeds thereof, any claims against or obligations of
Counterparty under the ISDA Master Agreement or any other confirmation
thereunder still outstanding shall be extinguished and thereafter not revive.
The Supplemental Interest Trust Trustee shall not have liability for any failure
or delay in making a payment hereunder to Bear Stearns due to any failure or
delay in receiving amounts in the Swap Account from the Trust created pursuant
to the Pooling and Servicing Agreement.

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

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

          request and at Bear Stearns' expense, take any reasonable steps
          required to be taken by Counterparty to effect such transfer.

(j) TRANSFER TO AVOID TERMINATION EVENT. Section 6(b)(ii) is hereby amended by
(i) deleting the words "or if a Tax Event Upon Merger occurs and the Burdened

inserting the following:

          "Notwithstanding anything to the contrary in Section 7 (as amended
          herein) and Part 5(i), any transfer by Bear Stearns under this Section
          6(b)(ii) shall not require the consent of Counterparty; provided that:

          (i)   the transferee (the "Transferee") is an Eligible Replacement;

          (ii)  if the Transferee is domiciled in a different country or
                political subdivision thereof from both Bear Stearns and
                Counterparty, such transfer satisfies the Rating Agency
                Condition;

          (iii) the Transferee will not, as a result of such transfer, be
                required on the next succeeding Scheduled Payment Date to
                withhold or deduct on account of any Tax (except in respect of
                default interest) amounts in excess of that which Bear Stearns
                would, on the next succeeding Scheduled Payment Date have been
                required to so withhold or deduct unless the Transferee would be
                required to make additional payments pursuant to Section 2(d)
                (i)(4) corresponding to such excess;

          (iv)  a Termination Event or Event of Default does not occur as a
                result of such transfer; and

          (v)   the Transferee confirms in writing that it will accept all of
                the interests and obligations in and under this Agreement which
                are to be transferred to it in accordance with the terms of this
                provision.

          On and from the effective date of any such transfer to the Transferee,
          Bear Stearns will be fully released from any and all obligations
          hereunder."

(k) PROCEEDINGS. Bear Stearns shall not institute against or cause any other
person to institute against, or join any other person in instituting against,

           defined under the Pooling and Servicing Agreement, to disclose
           certain financial information regarding Bear Stearns or its group of
           affiliated entities, if applicable, depending on the aggregate
           "significance percentage" of this Agreement and any other derivative
           contracts between Bear Stearns or its group of affiliated entities,
           if applicable, and Counterparty, as calculated from time to time in
           accordance with Item 1115 of Regulation AB.

     (ii)  It shall be a swap disclosure event ("SWAP DISCLOSURE EVENT") if, on
           any Business Day after the date hereof, the Depositor requests from
           Bear Stearns the applicable financial information described in Item
           1115 of Regulation AB (such request to be based on a reasonable

               provide a statement showing, in reasonable detail, how it arrived

               as follows:

               Party and not Transferred pursuant to this Paragraph will
               constitute Posted Collateral in the form of Cash and will be

     have entered and/or anticipate entering into one of more transactions (each
     a "Transaction") that are or will be governed by this Master Agreement,
     which includes the schedule (the "Schedule"), and the documents and other
     confirming evidence (each a "Confirmation") exchanged between the parties
     confirming those Transactions.

     Accordingly, the parties agree as follows: --

(1)  INTERPRETATION

1. DEFINITIONS. The terms defined in Section 14 and in the Schedule will have
the meanings therein specified for the purpose of this Master Agreement.

2. INCONSISTENCY. In the event of any inconsistency between the provisions of
the Schedule and the other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

3. SINGLE AGREEMENT. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

(2)  OBLIGATIONS

1. GENERAL CONDITIONS.

                                      U-2-1

<PAGE>

     a) Each party will make each payment or delivery specified in each
     Confirmation to be made by it, subject to the other provisions of this
     Agreement.

     b) Payments under this Agreement will be made on the due date for value on
     that date in the place of the account specified in the relevant
     Confirmation or otherwise pursuant to this Agreement, in freely
     transferable funds and in the manner customary for payments in the required
     currency. Where settlement is by delivery (that is, other than by payment),
     such delivery will be made for receipt on the due date in the manner
     customary for the relevant obligation unless otherwise specified in the
     relevant Confirmation or elsewhere in this Agreement.

     c) Each obligation of each party under Section 2(a)(i) is subject to (1)
     the condition precedent that no Event of Default or Potential Event of
     Default with respect to the other party has occurred and is continuing, (2)
     the condition precedent that no Early Termination Date in respect of the
     relevant Transaction has occurred or been effectively designated and (3)
     each other applicable condition precedent specified in this Agreement.

                                      U-2-2

<PAGE>

2. CHANGE OF ACCOUNT. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

3. NETTING. If on any date amounts would otherwise be payable: --

     a)   in the same currency; and

     b)   in respect of the same Transaction,

     by each party to the other. then, on such date, each party's obligation to
     make payment of any such amount will be automatically satisfied and
     discharged and, if the aggregate amount that would otherwise have been
     payable by one party exceeds the aggregate amount that would otherwise have
     been payable by the other party, replaced by an obligation upon the party
     by whom the larger aggregate amount would have been payable to pay to the
     other party the excess of the larger aggregate amount over the smaller
     aggregate amount.

     The parties may elect in respect of two or more Transactions that a net
     amount will be determined in respect of all amounts payable on the same
     date in the same currency in respect of such Transactions, regardless of
     whether such amounts are payable in respect of the same Transaction. The
     election may be made in the Schedule or a Confirmation by specifying that
     subparagraph (ii) above will not apply to the Transactions identified as
     being subject to the election, together with the starting date (in which
     case subparagraph (ii) above will not, or will cease to, apply to such
     Transactions from such date). This election may be made separately for
     different groups of Transactions and will apply separately to each pairing
     of Offices through which the parties make and receive payments or
     deliveries.

4. DEDUCTION OR WITHHOLDING FOR TAX.

     a) Gross-Up. All payments under this Agreement will be made without any
     deduction or withholding for or on account of any Tax unless such deduction
     or withholding is required by any applicable law, as modified by the
     practice of any relevant governmental revenue authority, then in effect. If
     a party is so required to deduct or withhold, then that party ("X") will:
     --

          (1) promptly notify the other party ("Y") of such requirement;

          (2) pay to the relevant authorities the full amount required to be
          deducted or withheld (including the full amount required to be
          deducted or withheld from any additional amount paid by X to Y under
          this Section 2(d)) promptly upon the earlier of determining that such
          deduction or withholding is required or receiving notice that such
          amount has been assessed against Y;

                                      U-2-3

<PAGE>

          (3) promptly forward to Y an official receipt (or a certified copy),
          or other documentation reasonably acceptable to Y, evidencing such
          payment to such authorities; and

          (4) if such Tax is an Indemnifiable Tax, pay to Y, in addition to the
          payment to which Y is otherwise entitled under this Agreement, such
          additional amount as is necessary to ensure that the net amount
          actually received by Y (free and clear of Indemnifiable Taxes. whether
          assessed against X or Y) will equal ft full amount Y would have
          received had no such deduction or withholding been required. However,
          X will not be required to pay any additional amount to Y to the extent
          that it would not be required to be paid but for: --

               (1) the failure by Y to comply with or perform any agreement
               contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

               (2) the failure of a representation made by Y pursuant to Section
               3(f) to be accurate and true unless such failure would not have
               occurred but for (I) any action taken by a taxing authority, or
               brought in a court of competent jurisdiction, on or after the
               date on which a Transaction is entered into (regardless of
               whether such action is taken or brought with respect to a party
               to this Agreement) or (II) a Change in Tax Law.

     b)   (ii) Liability. If: --

          (1) X is required by any applicable law, as modified by the practice
          of any relevant governmental revenue authority, to make any deduction
          or withholding in respect of which X would not be required to pay an
          additional amount to Y under Section 2(d)(i)(4);

          (2) X does not so deduct or withhold; and

          (3) a liability resulting from such Tax is assessed directly against
          X,

     then, except to the extent Y has satisfied or then satisfies the liability
     resulting from such Tax, Y will promptly pay to X the amount of such
     liability (including any related liability for interest, but including any
     related liability for penalties only if Y has failed to comply with or
     perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

5. DEFAULT INTEREST; OTHER AMOUNTS. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgment) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate

                                      U-2-4

<PAGE>

the other party on demand if and to the extent provided for in the relevant
Confirmation or elsewhere in this Agreement.

(3)  REPRESENTATIONS

     Each party represents to the other party (which representations will be
     deemed to be repeated by each party on each date on which a Transaction is
     entered into and, in the case of the representations in Section 3(f), at
     all times until the termination of this Agreement) that: --

          other party; or

                                      U-2-7

          repudiates or rejects, in whole or in part, or challenges the validity
          of, such Credit Support Document;

     d) Misrepresentation. A representation (other than a representation under
     Section 3(e) or (f)) made or repeated or deemed to have been made or
     repeated by the party or any Credit Support Provider of such party in this
     Agreement or any Credit Support Document proves to have been incorrect or
     misleading in any material respect when made or repeated or deemed to have
     been made or repeated;

     e) Default under Specified Transaction. The party, any Credit Support
     Provider of such party or any applicable Specified Entity of such party (1)

     applicable notice requirement or grace period, there occurs a liquidation
     of, an acceleration of obligations under, or an early termination of, that
     Specified Transaction, (2) defaults, after giving effect to any applicable
     notice requirement or grace period, in making any payment or delivery due
     on the last payment, delivery or exchange date of, or any payment on early
     termination of, a Specified Transaction (or such default continues for at
     least three Local Business Days if there is no applicable notice
     requirement or grace period) or (3) disaffirms, disclaims, repudiates or
     rejects, in whole or in part, a Specified Transaction (or such action is
     taken by any person or entity appointed or empowered to operate it or act
     on its behalf);

     f) Cross Default. If "Cross Default" is specified in the Schedule as
     applying to the party, the occurrence or existence of (1) a default, event
     of default or other similar condition or event (however described) in
     respect of such party, any Credit Support Provider of such party or any
     applicable Specified Entity of such party under one or more agreements or
     instruments relating to Specific Indebtedness of any of them (individually
     or collectively) in an aggregate amount of not less than the applicable
     Threshold Amount (as specified in the Schedule) which has resulted in such
     Specified Indebtedness becoming, or becoming capable at such time of being
     declared, due and payable under such agreements or instruments, before it
     would otherwise have been due and payable or (2) a default by such party,
     such Credit Support Provider or such Specified Entity (individually or
     collectively) in making one or more payments on the due date thereof in an
     aggregate amount of not less than the applicable Threshold Amount under
     such agreements or instruments (after giving effect to any applicable
     notice requirement or grace period);

     g) Bankruptcy. The party, any Credit Support Provider of such party or any
     applicable Specified Entity of such party:-

          (1) is dissolved (other than pursuant to a consolidation, amalgamation
          or merger); (2) becomes insolvent or is unable to pay its debts or
          fails or admits in writing its inability generally to pay its debts as
          they become due; (3) makes a general assignment, arrangement or

          insolvency law or other similar law affecting creditors' rights, or a
          petition is presented for its winding-up or liquidation, and, in the
          case of any such proceeding or petition instituted or presented
          against it, such proceeding or petition (A) results in a

                                      U-2-8

<PAGE>

          judgment of insolvency or bankruptcy or the entry of an order for
          relief or the making of an order for its winding-up or liquidation or
          (B) is not dismissed, discharged, stayed or restrained in each case
          within 30 days of the institution or presentation thereof, (5) has a

          (inclusive); or (9) takes any action in furtherance of, or indicating
          its consent to, approval of, or acquiescence in, any of the foregoing
          acts; or

     h) Merger Without Assumption. The party or any Credit Support Provider of
     such party consolidates or amalgamates with, or merges with or into, or
     transfers all or substantially all its assets to, another entity and, at
     the time of such consolidation, amalgamation, merger or transfer: -

          (1) the resulting, surviving or transferee entity fails to assume all
          the obligations of such party or such Credit Support Provider under
          this Agreement or any Credit Support Document to which it or its
          predecessor was a party by operation of law or pursuant to an
          agreement reasonably satisfactory to the other party to this
          Agreement; or

          (2) the benefits of any Credit Support Document fail to extend
          (without the consent of the other party) to the performance by such
          resulting, surviving or transferee entity of its obligations under
          this Agreement.

2. TERMINATION EVENTS. The occurrence at any time with respect to a party or, if
applicable, any Credit Support Provider of such party or any Specified Entity of
such party of any event specified below constitutes an Illegality if the event
is specified in (i) below, a Tax Event if the event is specified in (ii) below
or a Tax Event Upon Merger if the event is specified in (iii) below, and, if
specified to be applicable, a Credit Event Upon Merger if the event is specified
pursuant to (iv) below or an Additional Termination Event if the event is
specified pursuant to (v) below:--

     a) Illegality. Due to the adoption of, or any change in, any applicable law
     after the date on which a Transaction is entered into, or due to the
     promulgation of, or any change in, the interpretation by any court,
     tribunal or regulatory authority with competent jurisdiction of any
     applicable law after such date. it becomes unlawful (other than as a result
     of a breach by the party of Section 4(b)) for such party (which will be the
     Affected Party):--

                                      U-2-9

<PAGE>

          (1) to perform any absolute or contingent obligation to make a payment
          or delivery or to receive a payment or delivery in respect of such
          Transaction or to comply with any other material provision of this
          Agreement relating to such Transaction; or

          (2) to perform, or for any Credit Support Provider of such party to
          perform, any contingent or other obligation which the party (or such
          Credit Support Provider) has under any Credit Support Document
          relating to such Transaction;

     b) Tax Event. Due to (x) any action taken by a taxing authority, or brought
     in a court of competent jurisdiction, on or after the date on which a
     Transaction is entered into (regardless of whether such action is taken or
     brought with respect to a party to this Agreement) or (y) a Change in Tax
     Law, the party (which will be the Affected Party) will, or there is a
     substantial likelihood that it will, on the next succeeding Scheduled
     Payment Date (1) be required to pay to the other party an additional amount
     in respect of an Indemnifiable Tax under Section 2(d)(i)(4) (except in
     respect of interest under Section 2(e), 6(d)(ii) or 6(e)) or (2) receive a
     payment from which an amount is required to be deducted or withheld for or
     on account of a Tax (except in respect of interest under Section 2(e),
     6(d)(ii) or 6(e)) and no additional amount is required to be paid in
     respect of such Tax under Section 2(d)(i)(4) (other than by reason of
     Section 2(d)(i)(4)(A) or (B));

     c) Tax Event Upon Merger. The party (the "Burdened Party") on the next
     succeeding Scheduled Payment Date will either (1) be required to pay an
     additional amount in respect of an Indemnifiable Tax under Section
     2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
     6(e)) or (2) receive a payment from which an amount has been deducted or
     withheld for or on account of any Indemnifiable Tax in respect of which the
     other party is not required to pay an additional amount (other than by
     reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
     party consolidating or amalgamating with, or merging with or into, or
     transferring all or substantially all its assets to, another entity (which
     will be the Affected Party) where such action does not constitute an event
     described in Section 5(a)(viii);

     d) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified in
     the Schedule as applying to the party, such party ("X"), any Credit Support
     Provider of X or any applicable Specified Entity of X consolidates or
     amalgamates with, or merges with or into, or transfers all or substantially
     all its assets to, another entity and such action does not constitute an
     event described in Section 5(a)(viii) but the creditworthiness of the
     resulting, surviving or transferee entity is materially weaker than that of
     X, such Credit Support Provider or such Specified Entity, as the case may
     be, immediately prior to such action (and, in such event, X or its
     successor or transferee, as appropriate, will be the Affected Party); of

     e) Additional Termination Event. If any "Additional Termination Event" is
     specified in the Schedule or any Confirmation as applying. the occurrence
     of such event (and, in such event. the Affected Party or Affected Parties
     shall be as specified for such Additional Termination Event in the Schedule
     or such Confirmation).

3. EVENT OF DEFAULT AND ILLEGALITY. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.

(6)  EARLY TERMINATION

1. RIGHT TO TERMINATE FOLLOWING EVENT OF DEFAULT. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(l), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

2. RIGHT TO TERMINATE FOLLOWING TERMINATION EVENT.

     a) Notice. If a Termination Event occurs, an Affected Party will, promptly
     upon becoming aware of it, notify the other party, specifying the nature of
     that Termination Event and each Affected Transaction and will also give
     such other information about that Termination Event as the other party may
     reasonably require.

     b) Transfer to Avoid Termination Event. If either an Illegality under
     Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
     Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
     Affected Party, the Affected Party will, as a condition to its right to
     designate an Early Termination Date under Section 6(b)(iv), use all
     reasonable efforts (which will not require such party to incur a loss,
     excluding immaterial, incidental expenses) to transfer within 20 days after
     it gives notice under Section 6(b)(i) all its rights and obligations under
     this Agreement in respect of the Affected Transactions to another of its
     Offices or Affiliates so that such Termination Event ceases to exist.

     If the Affected Party is not able to make such a transfer it will give
     notice to the other party to that effect within such 20 day period,
     whereupon the other party may effect such a transfer within 30 days after
     the notice is given under Section 6(b)(i).

     Any such transfer by a party under this Section 6(b)(ii) will be subject to
     and conditional upon the prior written consent of the other party, which
     consent will not be withheld if such other party's policies in effect at
     such time would permit it to enter into transactions with the transferee on
     the terms proposed.

     c) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) or a Tax
     Event occurs and there are two Affected Parties, each party will use all
     reasonable efforts to reach agreement within 30 days after notice thereof
     is given under Section 6(b)(i) on action to avoid that Termination Event.

     d) Right to Terminate. If:--

                                     U-2-11

<PAGE>

          (1) a transfer under Section 6(b)(ii) or an agreement under Section
          6(b)(iii), as the case may be, has not been effected with respect to
          all Affected Transactions within 30 days after an Affected Party gives
          notice under Section 6(b)(i); or

          (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon Merger
          or an Additional Termination Event occurs, or a Tax Event Upon Merger
          occurs and the Burdened Party is not the Affected Party,

     either party in the case of an Illegality, the Burdened Party in the case
     of a Tax Event Upon Merger, any Affected Party in the case of a Tax Event
     or an Additional Termination Event if there is more than one Affected
     Party, or the party which is not the Affected Party in the case of a Credit
     Event Upon Merger or an Additional Termination Event if there is only one
     Affected Party may, by not more than 20 days notice to the other party and
     provided that the relevant Termination Event is then continuing, designate
     a day not earlier than the day such notice is effective as an Early
     Termination Date in respect of all Affected Transactions.

3. EFFECT OF DESIGNATION.

     a) If notice designating an Early Termination Date is given under Section
     6(a) or (b), the Early Termination Date will occur on the date so
     designated, whether or not the relevant Event of Default or Termination
     Event is then continuing.

     b) Upon the occurrence or effective designation of an Early Termination
     Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
     respect of the Terminated Transactions will be required to be made, but
     without prejudice to the other provisions of this Agreement. The amount, if
     any, payable in respect of an Early Termination Date shall be determined
     pursuant to Section 6(e).

4. CALCULATIONS.

     a) Statement. On or as soon as reasonably practicable following the
     occurrence of an Early Termination Date, each party will make the
     calculations on its part, if any, contemplated by Section 6(e) and will
     provide to the other party a statement (1) showing, in reasonable detail,
     such calculations (including all relevant quotations and specifying any
     amount payable under Section 6(e)) and (2) giving details of the relevant
     account to which any amount payable to it is to be paid. In the absence of
     written confirmation from the source of a quotation obtained in determining
     a Market Quotation, the records of the party obtaining such quotation will
     be conclusive evidence of the existence and accuracy of such quotation.

     b) Payment Date. An amount calculated as being due in respect of any Early
     Termination Date under Section 6(e) will be payable on the day that notice
     of the amount payable is effective (in the case of an Early Termination
     Date which is designated or occurs as a result of an Event of Default) and
     on the day which is two Local Business Days after the day on which notice
     of the amount payable is effective (in the case of an Early Termination
     Date which is designated as a result of a Termination Event). Such amount
     will be paid together with (to the extent permitted

                                     U-2-12

<PAGE>

     under applicable law) interest thereon (before as well as after judgment)
     in the Termination Currency, from (and including) the relevant Early
     Termination Date to (but excluding) the date such amount is paid, at the
     Applicable Rate. Such interest will be calculated on the basis of daily
     compounding and the actual number of days elapsed.

5. PAYMENTS ON EARLY TERMINATION. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
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.

     a) Events of Default. If the Early Termination Date results from an Event
     of Default:--

          (1) First Method and Market Quotation. If the First Method and Market
          Quotation apply, the Defaulting Party will pay to the Non-defaulting
          Party the excess, if a positive number, of (A) the sum of the
          Settlement Amount (determined by the Non-defaulting Party) in respect
          of the Terminated Transactions and the Termination Currency Equivalent
          of the Unpaid Amounts owing to the Non-defaulting Party over (B) the
          Termination Currency Equivalent of the Unpaid Amounts owing to the
          Defaulting Party.

          (2) First Method and Loss. If the First Method and Loss apply, the
          Defaulting Party will pay to the Non-defaulting Party, if a positive
          number, the Non-defaulting Party's Loss in respect of this Agreement.

          (3) Second Method and Market Quotation. If the Second Method and
          Market Quotation apply, an amount will be payable equal to (A) the sum
          of the Settlement Amount (determined by the Non-defaulting Party) in
          respect of the Terminated Transactions and the Termination Currency
          Equivalent of the Unpaid Amounts owing to the Non-defaulting Party
          less (B) the Termination Currency Equivalent of the Unpaid Amounts
          owing to the Defaulting Party. If that amount is a positive number,
          the Defaulting Party will pay it to the Non-defaulting Party; if it is
          a negative number, the Non-defaulting Party will pay the absolute
          value of that amount to the Defaulting Party.

          (4) Second Method and Loss. If the Second Method and Loss apply, an
          amount will be payable equal to the Non-defaulting Party's Loss in
          respect of this Agreement. If that amount is a positive number, the
          Defaulting Party will pay it to the Non-defaulting Party; if it is a
          negative number, the Non-defaulting Party will pay the absolute value
          of that amount to the Defaulting Party.

     b) Termination Events. If the Early Termination Date results from a
     Termination Event:--

          (1) One Affected Party. If there is one Affected Party, the amount
          payable will be determined in accordance with Section 6(e)(i)(3), if
          Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
          except that, in either case, references to the Defaulting Party and to
          the Non-defaulting Party will be deemed to be references to the
          Affected Party and the party which is not the Affected Party,
          respectively, and, if Loss applies and fewer

                                     U-2-13

<PAGE>

          than all the Transactions are being terminated, Loss shall be
          calculated in respect of all Terminated Transactions.

          (2) Two Affected Parties. If there are two Affected Parties:--

               (1) if Market Quotation applies, each party will determine a
               Settlement Amount in respect of the Terminated Transactions, and
               an amount will be payable equal to (I) the sum of (a) one-half of
               the difference between the Settlement Amount of the party with
               the higher Settlement Amount ("X") and the Settlement Amount of
               the party with the lower Settlement Amount ("Y") and (b) the
               Termination Currency Equivalent of the Unpaid Amounts owing to X
               less (II) the Termination Currency Equivalent of the Unpaid
               Amounts owing to Y; and

               (2) if Loss applies, each party will determine its Loss in
               respect of this Agreement (or, if fewer than all the Transactions
               are being terminated, in respect of all Terminated Transactions)
               and an amount will be payable equal to one-half of the difference
               between the Loss of the party with the higher Loss ("X") and the
               Loss of the party with the lower Loss ("Y").

          If the amount payable is a positive number, Y will pay it to X; if it
          is a negative number, X will pay the absolute value of that amount to
          Y.

     c) Adjustment for Bankruptcy. In circumstances where an Early Termination
     Date occurs because "Automatic Early Termination" applies in respect of a
     party, the amount determined under this Section 6(e) will be subject to
     such adjustments as are appropriate and permitted by law to reflect any
     payments or deliveries made by one party to the other under this Agreement
     (and retained by such other party) during the period from the relevant
     Early Termination Date to the date for payment determined under Section
     6(d)(ii).

     d) Pre-Estimate. The parties agree that if Market Quotation applies an
     amount recoverable under this Section 6(e) is a reasonable pre-estimate of
     loss and not a penalty. Such amount is payable for the loss of bargain and
     the loss of protection against future risks and except as otherwise
     provided in this Agreement neither party will be entitled to recover any
     additional damages as a consequence of such losses.

(7)  TRANSFER

     Subject to Section 6(b)(ii), 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 without the prior written consent of
     the other party, except that:--

1. a party may make such a transfer of this Agreement 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); and

2. 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).

                                     U-2-14

<PAGE>

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

(8)  CONTRACTUAL CURRENCY

1. PAYMENT IN THE CONTRACTUAL CURRENCY. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

2. JUDGMENTS. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

3. SEPARATE INDEMNITIES. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

4. EVIDENCE OF LOSS. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.

understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

2. AMENDMENTS. No amendment, modification or waiver in respect of this Agreement
will be effective unless in writing (including a writing evidenced by a
facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

     facsimile transmission), each of which will be deemed an original.

     b) The parties intend that they are legally bound by the terms of each
     Transaction from the moment they agree to those terms (whether orally or
     otherwise). A Confirmation shall be entered into as soon as practicable and
     may be executed and delivered in counterparts (including by facsimile

1. GOVERNING LAW. This Agreement will be governed by and construed in accordance
with the law specified in the Schedule.

2. JURISDICTION. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably:--

     a) submits to the jurisdiction of the English courts, if this Agreement is
     expressed to be governed by English law, or to the non-exclusive
     jurisdiction of the courts of the State of New York and the United States
     District Court located in the Borough of Manhattan in New York City, if
     this Agreement is expressed to be governed by the laws of the State of New
     York; and

     b) waives any objection which it may have at any time to the laying of
     venue of any Proceedings brought in any such court, waives any claim that
     such Proceedings have been brought in an inconvenient forum and further
     waives the right to object, with respect to such Proceedings, that such
     court does not have any jurisdiction over such party.

     Nothing in this Agreement precludes either party from bringing Proceedings
     in any other jurisdiction (outside, if this Agreement is expressed to be
     governed by English law, the Contracting States, as defined in Section 1(3)
     of the Civil Jurisdiction and Judgments Act 1982 or any modification,

     bringing of Proceedings in any other jurisdiction.

3. SERVICE OF PROCESS. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any reason any party's
Process Agent is unable to act as such, such party will promptly notify the
other party and within 30 days appoint a substitute process agent acceptable to
the other party. The parties irrevocably consent to service of process given in
the manner provided for notices in Section 12. Nothing in this Agreement will

court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

     "Loss" means, with respect to this Agreement or one or more Terminated

     negative number) in connection with this Agreement or that Terminated
     Transaction or group of Terminated Transactions, as the case may be,
     including any loss of bargain, cost of funding or, at the election of such

     losses and costs (or gains) in respect of any payment or delivery required
     to have been made (assuming satisfaction of each applicable condition
     precedent) on or before the relevant Early Termination Date and not made,
     except, so as to avoid duplication, if Section 6(c)(i)(1) or (3) or
     6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
     out-of-pocket expenses referred to under Section 11. A party will determine
     its Loss as of the relevant Early Termination Date, or, if that is not
     reasonably practicable, as of the earliest date thereafter as is reasonably
     practicable. A party may (but need not) determine its Loss by reference to
     quotations of relevant rates or prices from one or more leading dealers in
     the relevant markets.

     "Market Quotation" means, with respect to one or more Terminated
     Transactions and a party making the determination, an amount determined on
     the basis of quotations from Reference Market-makers. Each quotation will
     be for an amount, if any, that would be paid to such party (expressed as a
     negative number) or by such party (expressed as a positive number) in
     consideration of an agreement between such party (taking into account any
     existing Credit Support Document with respect to the obligations of such
     party) and the quoting Reference Market-maker to enter into a transaction
     (the "Replacement Transaction") that would have the effect of preserving
     for such party the economic equivalent of any payment or delivery (whether
     the underlying obligation was absolute or contingent and assuming the
     satisfaction of each applicable condition precedent) by the parties under
     Section 2(a)(i) in respect of such Terminated Transaction or group of
     Terminated Transactions that would, but for the occurrence of the relevant
     Early Termination Date, have been required after that date. For this
     purpose, Unpaid Amounts in respect of the Terminated Transaction or group
     of Terminated 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 is to be included.
     The Replacement Transaction would be subject to such documentation as such
     party and the Reference

                                     U-2-21

<PAGE>

     Market-maker may, in good faith, agree. The party making the determination
     (or its agent) will request each Reference Market-maker to provide its
     quotation 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 relevant Early Termination Date. The day and time as
     of which those quotations are to be obtained 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 more than
     three quotations are provided, the Market Quotation will be the arithmetic
     mean of the quotations, without regard to the quotations having the highest
     and lowest values, If exactly three such quotations are provided, the
     Market Quotation will be the quotation remaining after disregarding the
     highest and lowest quotations. For this purpose, if more than one quotation
     has the same highest value or lowest value, then one of such quotations
     shall be disregarded. If fewer than three quotations are provided, it will
     be deemed that the Market Quotation in respect of such Terminated
     Transaction or group of Terminated Transactions cannot be determined.

     "Non-default Rate" means a rate per annum equal to the cost (without proof
     or evidence of any actual cost) to the Non-defaulting Party (as certified

     selected by the party determining a Market Quotation in good faith (a) from
     among dealers of the highest credit standing which satisfy all the criteria
     that such party applies generally at the time in deciding whether to offer
     or to make an extension of credit and (b) to the extent practicable, from
     among such dealers having an office in the same city.

     "Relevant Jurisdiction" means, with respect to a party, the jurisdictions
     (a) in which the party is incorporated, organised, managed and controlled
     or considered to have its seat, (b) where an Office through which the party
     is acting for purposes of this Agreement is located, (c) in which the party
     executes this Agreement and (d) in relation to any payment, from or through
     which such payment is made.

     "Scheduled Payment Date" means a date on which a payment or delivery is to
     be made under Section 2(a)(i) with respect to a Transaction.

     Termination Date, the sum of.-

such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

     Termination Currency Equivalents of the fair market values reasonably
     determined by both parties.

Exhibit 10.1

Execution
Copy

INTELLECTUAL PROPERTY LICENSE AGREEMENT

PARTIES

          This Intellectual Property License Agreement (this “Agreement”) is made and entered into as of
November 30, 2006 by and between General Motors Corporation, a Delaware corporation, and those of
its Vauxhall Motors Ltd., Opel Eisenach GmbH, Saab Automobile AB, Saturn Corporation and OnStar
Corporation Subsidiaries who choose to join General Motors Corporation as a party to this Agreement
pursuant to execution of an Opt-in Letter in the form of exhibits attached hereto and incorporated
herein by reference (referred to collectively as “GM”), and GMAC LLC, a Delaware limited liability
company (“Licensee”).

RECITALS

          A. GM, directly and through its Subsidiaries, as defined in this Agreement, is a worldwide
manufacturer, distributor, marketer, and seller of motor vehicles and related goods and services
(“GM Products”).

          B. Licensee is a worldwide diversified financial services company that directly, and through
its Subsidiaries, provides automotive and non-automotive finance and lease, insurance, banking,
mortgage lending, and other services to a variety of affiliated and unaffiliated, consumer and
commercial customers.

          C. GM and Licensee provide significant services and resources to each other. The
transactions, relationships, interactions and dealings between GM and Licensee (“Dealings”)
contribute significantly to the success of GM and Licensee, generally providing efficiencies and
enhanced results for each of them, including business opportunities and referrals, data and
resource sharing, economies of scale, leveraging staff expertise, and administrative conveniences.
These efficiencies flow from, among other things, four aspects of their relationship: (1) the
formal ownership structure that existed historically, resulting in tax, legal, and administrative
efficiencies; (2) propinquity, familiarity, and common corporate culture and industry experience
allowing informal and simplified interactions; (3) sound business practices, including economies of
scale and leveraging of resources; and (4) their “shared” or “common” customers (i.e., GM dealers
and purchasers of GM motor vehicles). Combined, these efficiencies result in highly valuable and
significant organizational, operational, business and financial synergies. Although specific
aspects of the Dealings entered into at arm’s length as described in this Agreement may benefit one
party more than the other from time to time, these synergies produce net positive effects for GM
and Licensee jointly, and for each company individually to a commensurate degree.

          D. GM and Licensee have undertaken to formally document certain of the Dealings related to the
material services provided by GM and its Subsidiaries to Licensee and its Subsidiaries and vice
versa in several services agreements entered into concurrently herewith, including a Marketing
Services Agreement, Dealer Financing Service Agreement, Consumer Financing Service Agreements,
Remarketing Service Agreement, the European Cooperation Agreement and the Information Technology
Agreement (each between GM and Licensee) and an Insurance Services Agreement (between GM and
Licensee’s GMAC Insurance Holdings, Inc.

 

 

subsidiary) and a Licensing and Co-operation Agreement dated 28 February 2002 (among GM Holden
Ltd. Interleasing (Australia) Ltd and TVPR Pty Limited) (collectively “Services Agreements”).

          E. GM and Licensee desire to grant to the other licenses and rights with respect to its
trademarks and other intellectual property, subject to the terms and conditions provided in this
Agreement.

AGREEMENT

          In consideration of the promises and the mutual covenants and agreements and the
representations and warranties contained in this Agreement, and for other good and valuable

ARTICLE III

LICENSE OF INTELLECTUAL PROPERTY

Section 3.1 License to GM Trademarks.

          (a) License to Nameplate Trademarks. GM grants Licensee a non-exclusive,
non-transferable, royalty-free and worldwide license to use and display the Nameplate Trademarks
for the sole purpose of performing, marketing, advertising, and promoting: (i) the services
contemplated by the Services Agreements; (ii) financial services provided in Mexico through
Licensee’s Mexican subsidiary, Masterlease S.A. de C.V., to purchasers of GM products. Licensee is
prohibited from using the Nameplate Trademarks in connection with any trade name or business name.

          (b) License to GM PROTECTION PLAN and GM MOTOR CLUB. GM grants Licensee an exclusive,
non-transferable and royalty-bearing license to use and display the

3

 

“GM PROTECTION PLAN”, “GENERAL MOTORS PROTECTION PLAN” and “GM MOTOR CLUB” names
and logos solely in the United States and solely in connection with the operation, marketing,
advertising, and promoting of Licensee’s GM Protection Plan and GM Motor Club businesses. Subject
to Article VI of this Agreement, GM will exercise due care in its protection of the GM PROTECTION
PLAN, GENERAL MOTORS PROTECTION PLAN and GM MOTOR CLUB names and logos to protect Licensee’s use of
such names and logos exclusive of infringing uses by third parties.

          (c) License to GMAC Name and Logo. GM grants Licensee a non-transferable, exclusive
(including with respect to GM), royalty-free and worldwide license to use and display the GMAC name
and logo in connection with the operation, marketing, advertising, and promoting (including use of
the GMAC name and logo to manufacture, have manufactured, distribute and sell consumer merchandise
such as apparel, cups, key chains or other similar novelty items) of its current automotive and
non-automotive finance, lease, insurance, banking, mortgage, and lending businesses (“Business”).
Licensee may use the GMAC name and logo for existing lines of business (including financing of
dealerships which sell, begin selling, or expand their sale of products of third party motor
vehicle manufacturers and for customers of such dealerships) and those expressly set forth in
Exhibit 6, attached hereto and incorporated herein by reference. Licensee may request a license to
use the GMAC name and logo in connection with any new financial services business or in connection
with providing services to third party motor vehicle manufacturers. GM will determine, in its sole
discretion, whether to grant any such additional licenses and whether any such grant will be
royalty bearing. Licensee agrees to notify GM of its intention to begin use of the GMAC name and
logo in a new country prior to use to allow GM adequate time to determine the availability of the
GMAC name and logo for use in such country and, if necessary or upon Licensee’s request, file
corresponding trademark applications to protect Licensee’s intended use. GM agrees that if it
declines to file, prosecute, maintain, obtain or renew an application or registration for the GMAC
name and logo for use in connection with the Business or, if requested by Licensee, a new business,
Licensee has the right, at its cost and upon notice to GM, to file, prosecute, maintain, obtain, or
renew such trademark application or registration in GM’s name. Notwithstanding anything to the
contrary contained in this Agreement, GM will not be prohibited from using or displaying the GMAC
name and logo in connection with GM’s marketing, advertising and promotional activities to
reference the services being performed by the Licensee under the Service Agreements.

          (d) License to Licensee Trademarks. Licensee hereby grants GM a non-transferable,
non-exclusive, royalty-free and worldwide license to use and display the trademarks of Licensee,
such as SmartLease and SmartBuy, in connection with GM’s marketing, advertising and promotional
activities to reference the services being performed by the Licensee under the Service Agreements.
GM’s use of the Licensee’s trademarks will be limited to only those of Licensee’s trademarks that
are being used by Licensee in connection with the applicable Service Agreement and GM will be
prohibited from using the Licensee’s trademarks in connection with any trade name or business name.

Section 3.2 License to “GENERAL MOTORS” and “GM”. Subject to Sections 3.1(b) and 3.1(c) of
this Agreement, GM grants to Licensee a non-exclusive, non-transferable, royalty-free and worldwide
license to use the “GENERAL MOTORS” and “GM” names as part of its trade names or business names,
currently “General Motors Acceptance Corporation” and similar

4

 

names in other jurisdictions (e.g., GM Acceptance Ltda. in Argentina). Any proposed changes or
additions to current trade names or business names incorporating the GENERAL MOTORS or GM names
must be approved by GM prior to use, which approval will not be unreasonably withheld or delayed.
The license provided for in this Section 3.2 terminates fifteen (15) months from the effective date
of this Agreement, except with respect to Licensee’s use of “GENERAL MOTORS” as part of “GENERAL
MOTORS ACCEPTANCE CORPORATION” in the United States and Canada. Reasonable extensions of this
termination date will be granted by GM in the event of delays imposed by local regulatory
authorities. GM agrees that it will not license use of the GENERAL MOTORS or GM name to any party,
other than Licensee, during the term of this Agreement for use in connection with any trade name or
business name that is identical, or confusingly similar, to “General Motors Acceptance
Corporation”, “GM Acceptance Corporation” or “GMAC”.

Section 3.3 Manner of Use. The parties will use and display the trademarks of the other
party only in the form, color, dimension, and manner approved by the party owner (including use in
connection with internet domain names), and in accordance with any written trademark guidelines
provided thereby. GM acknowledges that Licensee may, in connection with a particular promotion or
event, have a need to make non-permanent, minor changes to the appearance of the GMAC name or logo,
such as changes to font type or coloring. GM will not object to such changes and no prior approval
of GM is required. Upon a party’s written request, the other party will furnish samples of
proposed advertising, brochures, marketing and promotional materials, and other documentation in
connection with its use of the requesting party’s trademarks. Except with respect to the GMAC name
and logo, the parties will, and will ensure that their Subsidiaries make any changes to its use of
the other party’s trademarks, as reasonably requested by the party owner, including, but not
limited to, changing the use of one or more of the trademarks within a commercially reasonable
time. Licensee further agrees and will ensure that it and its Subsidiaries will not use any GM
Trademarks, other than the GMAC name and logo, in advertising or promotional activities with third
party motor vehicle manufacturers. If GM requests that Licensee make changes to the appearance of
the GMAC name or logo from its appearance as exists as of the date of this Agreement, Licensee and
GM will work together to arrive at a good faith estimate of the costs Licensee will reasonably
incur in connection with its implementation of the requested change. If, after arriving at a
mutually-agreeable good faith estimate, GM requires Licensee to proceed with such changes, GM
agrees to reimburse Licensee for the costs it incurs in connection with making the required
changes, not to exceed the mutually-agreed upon good faith estimate. The parties also agree, and
will ensure that their respective sublicensees, stop using any trademarks of the other party in any
advertising or promotional activity if the other party objects on the basis that such advertising
or promotional activity would be unethical, in poor taste, misleading, deceptive, or in its sole
discretion, would reflect unfavorably on them.

Section 3.4 Notice of Ownership. Unless otherwise agreed to by the parties on a
case-by-case basis, the parties, consistent with historical and current practice in connection with
their own trademarks, will use the following notice somewhere in its advertising, brochures,
nationally distributed marketing and promotional materials, and other similar advertising and
marketing material (but not including business cards, letterhead, memo pads, envelopes, and other
stationary items; e-mail notices; press releases, rate sheets, and local dealer communications; and

5

 

other similar non-advertising and non-marketing material) in a conspicuous location in connection
with its use of the other party’s trademarks.

          “[“Trademarks”] are trademarks of [the other party], used under license by [party].”

          When displaying the GMAC trademark, the following is allowed instead of the foregoing notice:

          “GMAC is a registered trademark.”

          The parties acknowledge and agree that the notice requirement of this Section 3.4 does not
apply to any materials printed prior to the date of this Agreement, even if such printed materials
are distributed after the date of this Agreement; provided, however, that to the extent that
reprintings of such materials are made after the date of this Agreement, the aforementioned notice
will be included therein.

Section 3.5 Other Intellectual Property Rights.

          (a) GM Grant. GM grants Licensee a non-transferable, non-exclusive, royalty-free and
worldwide license under all GM patents (including the right to make, have made, use, have used,
offer for sale, and sell), copyrights (including the right to reproduce, prepare derivative works,
distribute and publicly display or perform), trade secrets and other forms of intellectual
property, excluding trademark rights, currently used by Licensee in the conduct of their Business
or as necessary for performing, marketing, advertising and promoting the services contemplated
under by the Service Agreements. The license grant of this Section 3.5(a) is limited to use by
Licensee in the conduct of its Business and, other than as expressly set forth in Section 3.7
hereunder, Licensee is expressly prohibited from granting any sublicense to Licensee’s parent or
it’s parent’s affiliates.

          (b) Licensee Grant. Licensee grants GM a non-transferable, non-exclusive,
royalty-free, and worldwide license under all Licensee patents (including the right to make, have
made, use, have used, offer for sale, and sell), copyrights (including the right to reproduce,
create derivative works, distribute and publicly display or perform), trade secrets and other forms
of intellectual property, excluding trademark rights, currently used by GM in the conduct of its
business or as necessary in connection with GM’s marketing, advertising and promoting the services
being performed by the Licensee under the Service Agreements. The license grant of this Section
3.5(b) is limited to use by GM in the conduct of its business and, other than as expressly set
forth in Section 3.7 hereunder, GM is expressly prohibited from granting any sublicense to GM’s
affiliates.

Section 3.6 Consumer Merchandise. Unless otherwise agreed and except with respect to the
use of the GMAC name and logo by Licensee, neither party is granted any right or license under this
Agreement to sell, or otherwise distribute for sale (collectively, to merchandise), any
merchandise, novelty items, or other goods bearing the trademarks or other intellectual property of
the other party, without the express written consent of the owner of the respective trademark or
other intellectual property. If either party requests to use the other party’s trademarks or other
intellectual property for merchandising, the parties will discuss such request in good faith,

6

 

including fees associated with such use of the trademarks and other intellectual property, if any.
The parties will document any agreement resulting from such discussions.

Section 3.7 Sublicense. Absent approval by the trademark or other intellectual property
owner, sublicensing of the trademarks or other intellectual property of the owner is
prohibited except as follows:

          (a) Subsidiaries. A party may sublicense and allow its Subsidiaries to use the other
party’s trademarks and other intellectual property subject to the terms of this Agreement;

          (b) Capmark Financial Group Inc. Licensee may sublicense the GMAC name and/or logo to
Capmark Financial Group Inc. but only to the extent of the Trademark License Agreement between
Licensee and Capmark Financial Group dated March 23, 2006.

          (c) Existing third party arrangements. Licensee and its Subsidiaries may continue,
renew, amend, or replace any license or sublicense of the GMAC name and/or logo to third parties
under licensing sublicensing arrangements existing as of the date hereof. In the event of any
inconsistency between this Agreement and any such arrangements, the terms of this Agreement govern.

          (d) Future third party arrangements: Licensee acknowledges that it has sought to
identify on Exhibit 8 the categories of activities for which, and categories of Persons to which,
Licensee and its Subsidiaries currently license and sublicense, and have historically licensed and
sublicensed, the GMAC name and logo (“Approved Categories”). Licensee may grant to third parties
sublicenses of the GMAC name and logo not in existence as of the date hereof provided that they
fall within the Approved Categories.

          If there are one or more categories of activities or entities for which Licensee or its
Subsidiaries have historically licensed or sublicensed the GMAC name and/or logo to third parties
as of the date hereof, but which are not listed in Exhibit 8, Licensee will promptly upon discovery
send a revised Exhibit 8 to GM that includes such missing category, and upon delivery of the
revised Exhibit 8 to GM, such category will be deemed one of the “Approved Categories” for which
sublicensing is permitted hereunder.

          If one of the exceptions above does not apply, and Licensee seeks GM’s consent to sublicense
the GMAC name and/or logo, GM will respond to such request within a reasonable amount of time. GM
will advise Licensee as to the individuals or business functions that would be involved in
responding to the request and a reasonable estimate of the amount of time that GM will take to
respond to the request. Any such sublicense will be subject to the terms hereof.

          If requested by the trademark or other intellectual property owner for the purpose of
fulfilling a registration or recordal requirement under local law or regulations, the other party
will use reasonable best efforts to cause its sublicensees to enter into a separate intellectual
property license agreement that is substantially identical to this Agreement.

Section 3.8 Royalty.

          (a) Royalty for License to GM PROTECTION PLAN. In payment for Licensee’s use of the
license to the GM PROTECTION PLAN and GENERAL MOTORS PROTECTION PLAN trademarks granted pursuant to
section 3.1(b) of this Agreement, Licensee will pay GM a royalty of 3.25% of the dealer cost (as
that term is used in the GM Protection Plan program) received by Licensee or its Subsidiaries, net
of cancellations, on sales of the GM Protection Plan, excluding contracts sold to GM, e.g. in
connection with GM’s promotion of a particular model vehicle, and excluding base contracts for GM
Certified Used Vehicles. Base contracts are those provided to the retail customer without a charge
identified separately from the price of the vehicle.

          (b) Royalty for License to GM MOTOR CLUB. In payment for Licensee’s use of the
license to the GM MOTOR CLUB trademark granted pursuant to section 3.1(b) of this Agreement,
Licensee will pay GM a royalty of 3.25% of the revenues, net of cancellations, of the GM Motor
Club.

          (c) Royalties for use of trademarks of GM Subsidiaries in situations analogous to Sections
3.1(b) will be set forth in the relevant Opt-in Letter, in which case the terms of such Opt-in
Letter must be accepted by Licensee.

          (d) Guaranteed Minimum Royalty. Licensee agrees that it will pay guaranteed minimum
Royalties in the amount of $15 million per year on a pre-tax basis, only until the exclusive
license granted in Section 3.1(b) is terminated under Section 5.2(d) in whole or in part.

          (e) Statements and Royalty Payments. In connection with the royalties in subsections
(a), (b) and, if any, (c), Licensee will furnish to GM not later than thirty days after the end of
each calendar month: (1) complete and accurate monthly statements showing (i) the dealer cost
received by Licensee or its Subsidiaries on sales of the GM Protection Plan during the preceding
month and any applicable deductions for cancellations; and (ii) revenues of the GM Motor Club
during the preceding month and any applicable deductions for cancellations; and (2) a check in
payment of the royalty due from such sales and revenues as reported in (1) above. The receipt or
acceptance by GM of any of the statements furnished pursuant to this Agreement or any royalties
paid hereunder (or the cashing of any royalty checks paid hereunder) will not preclude GM from
questioning the correctness of or mistakes which are discovered in such statements or payments, and
in the event that any inconsistencies or mistakes are discovered in such statements or payments,
they will promptly upon notice be rectified and the appropriate payments made by Licensee provided,
however, that if GM fails to notify Licensee of a potential dispute within two years after receipt
of a statement or payment, GM will be deemed to have waived any claims with respect thereto. If
any amount due and payable hereunder is not made on the due date, then, without prejudice to any
other rights of GM, GM will charge interest on such outstanding amount at the rate of 1.00
percentage point above the prime rate as quoted in the Wall Street Journal from the due date until
the date of payment.

          (f) Records. Licensee will keep accurate books of account and records covering all
transactions relating to the payment of royalties in this Agreement, and GM or its

8

 

nominee will have the right at all reasonable business hours to examine said books of account
and records and all other documents and material in the possession or under the control of Licensee
with respect to the payment of royalties under this Agreement, and will have free and full access
thereto for said purposes and for the purpose of making extracts therefrom. Licensee must
segregate its records in such a manner as to facilitate a complete audit and agrees that such audit
may be used as a basis of settlement of charges in accordance with this Agreement. If it is
determined that there is a deficiency of 5% or more in the royalties paid or owed to GM, then
Licensee will bear all reasonable expenses related to such verification, examination or audit by GM
(or its nominee). Examinations under this paragraph will be conducted during normal business hours
with notice of such examination provided to Licensee at least one week prior to such examination,
and not more often than once each calendar year. All books of account and records will be kept
available for at least two years after the expiration or termination of this Agreement.

Section 3.9 Domain Names. The licenses to use the other party’s trademarks granted under
this Agreement include the right to register and use internet domain names (i.e., URLs) comprising,
in whole or in part, the licensed trademarks of the other party, subject to the following:

          (a) the use must otherwise comply with the terms and conditions of this Agreement;

          (b) the registrant will cease using and will transfer ownership of any such internet domain
name to the other party (i.e., trademark owner) upon the other party’s written request at any time
during the term of this Agreement, unless:

          (i) the domain name incorporates the GMAC trademark, in which case, the Licensee may continue
to use it throughout the term of this Agreement; or

          (ii) subject to Section 3.9(b)(i) above, the domain name also includes the trademark of the
domain name registrant or another party, in which case it need not be assigned but must be
abandoned.

          (c) any cessation of use, transfer, or abandonment of a domain name required under this
Subsection 3.9 will be done as promptly as practicable without disrupting the business of the
domain name registrant; and

          (d) transferring ownership of any domain name incorporating the trademarks of the other party
to any party other than the trademark owner is specifically prohibited.

Section 3.10 Continuation of Certain Rights Upon Transfer of a Subsidiary. Any sublicense
to a Subsidiary of Licensee terminates if such Subsidiary ceases to be a Subsidiary as a result of:
(i) Licensee’s transferring in one or more transactions 50% or more of the voting interests of the
Transferred Entity to a third party; or (ii) a public offering of the equity securities of any
Subsidiary of Licensee such that a Change in Control occurs (any such entity described in (i) or
(ii), a “Transferred Entity”), provided that Licensee or, in the case of (ii) above, the applicable
Subsidiary, may request GM to license the GMAC name and logo to the Transferred Entity on a
non-exclusive, royalty-free basis for the remaining term of this Agreement (“License Request”).

9

 

GM will respond to the License Request in a reasonable time. If the following conditions are met,
GM may not unreasonably withhold its consent to the License Request, or condition its consent in an
unreasonable manner such as by requiring a payment or other consideration in return for its consent
to the License Request and must negotiate in good faith a license agreement with the Transferred
Entity on terms substantially similar to those in this Agreement:

          (a) the Transferred Entity is not engaged in the auto finance business;

          (b) the GMAC name and logo is material to the business of the Transferred Entity;

          (c) the Transferred Entity agrees to be bound by obligations substantially similar to those in
this Agreement and to the following additional obligations:

               (i) to indemnify GM, and its directors, employees, representatives, and agents from any and
all Losses relating to the Transferred Entity’s use of the GMAC name and logo in connection with
its business, except for claims relating to trademark infringement for use of the GMAC name and
logo as permitted by the license agreement;

               (ii) to indemnify GM and its directors, employees, representatives, and agents from any and
all Losses relating to imputation by any taxing authority of royalty income; and

               (iii) to meet quality and service standards appropriate for the industry in connection with
the business operations in which the Transferred Entity uses the GMAC name or logo.

          (d) The license to the Transferred Entity is limited (i) to use in the United States, Canada,
Mexico, and United Kingdom in connection with the Business, and (ii) use in the additional
countries of Germany and The Netherlands in connection with mortgage and lending operations, with a
reasonable transition period to cease using the GMAC name and logo in any other jurisdiction; and

          (e) neither the transferee nor any of its Affiliates is a competitor of GM or any of its
Subsidiaries in the business of the manufacture and distribution of motor vehicles, powertrains and
components of powertrains, and spare parts; except that such transferee or its Affiliates may
retain, purchase or otherwise acquire (directly or indirectly) up to 5% of the outstanding shares
of capital stock of any such business listed on a national securities exchange or publicly traded
in the over-the-counter market without being deemed to be such a “competitor”.

If Licensee or the Transferred Entity did not submit a License Request to GM or GM did not approve
such License Request, the Transferred Entity must discontinue using the GMAC name and logo within
60 days following the transfer.

Any sublicense to a Subsidiary of GM terminates if such entity ceases to be a Subsidiary of GM.

ARTICLE IV

OWNERSHIP

Section 4.1 The parties acknowledge that all right, title and interest in and goodwill attaching to
the other party’s trademarks are and will remain vested in such other party, and neither party will
take or assist any other person to take any action that may invalidate, prejudice or impair the
other party’s right, title and interest in and to their respective trademarks.

Section 4.2 Neither party will challenge the other party’s title to such other party’s trademarks
or challenge the validity of this Agreement. Neither party will register or record the trademarks
of the other party, nor use or attempt to register any trademark or trade name that is confusingly
similar thereto (or a transliteration or translation thereof) in any state, region or country,
except as expressly allowed by this Agreement.

Section 4.3 Any and all trademark rights that are derived from use of the trademarks of the other
party will inure solely to the benefit of, and be on behalf of, such other party.

Section 4.4 Costs. Licensee will reimburse GM for all third party costs incurred by GM in
connection with its management of the GMAC name and logo, including the search, clearance,
application, registration, renewal, enforcement and protection of the GMAC name and logo,
worldwide, and recordal of this Agreement or any registered user agreement relating to this
Agreement. These costs will be paid monthly in arrears, within 30 days of the invoice date. If
any amount due and payable hereunder is not made by the due date then, without prejudice to any
other rights of GM, GM will charge interest on such outstanding amount at the rate of 1.00
percentage point above the prime rate as quoted in the Wall Street Journal from the due date until
the date of payment

ARTICLE V

TERM; TERMINATION

     Section 5.1 Term. The initial term of this Agreement commences on the date as set forth in
the preamble section of this Agreement entitled “Parties”, and, unless earlier terminated as
provided for in Section 5.2, expires on the 10th anniversary. Upon the expiration of the initial
or any renewal term of this Agreement, the term of this Agreement will be automatically renewed for
an additional one (1) year period. If any of the Services Agreements are extended by the parties
thereto, then this Agreement will be automatically extended as to be coterminous with such extended
Services Agreement. For purposes of this Agreement, “Term” means the initial term and any renewal
term.

     Section 5.2 Termination of the Agreement. This Agreement may be terminated as follows:

          (a) By either party at the end of the Term upon three years notice prior to the end of any
Term; provided, however, that the license grant of Section 3.1(a)(ii) may be terminated by either
party upon one-year prior written notice at any time;

11

 

          (b) By either party upon the 30th day after giving notice to the other party of material
breach of this Agreement by such other party, if such material breach has not been cured to the
reasonable satisfaction of the non-breaching party on or before such 30th day, however, if such
breach is not capable of cure within such 30-day period and the breaching party is acting
diligently to accomplish a timely cure, this Agreement will not terminate until the expiration of a
reasonable period for the completion of the cure to the reasonable satisfaction of the
non-breaching party, but, in any event, not more than 90 days after the date of the notice of
breach;

          (c) If any Governmental Authority requires GM or Licensee to terminate this Agreement or any
material obligation(s) under it; any such termination will be effective as of the effective date of
such required termination; and

          (d) Upon termination of the exclusivity provisions under the Dealer Financing Service
Agreement or any of the Consumer Financing Services Agreements, GM may, at its option, terminate
this Agreement with respect to Licensee’s use of (i) the GM PROTECTION PLAN, GENERAL MOTORS
PROTECTION PLAN and GM MOTOR CLUB names and logos provided for in Section 3.1(b); (ii) the SATURN
SERVICE PLAN names and logos provided for in Exhibit 5, and (iii) the GMAC name and logo in
connection with its automotive related businesses as provided for in part, in Section 3.1(c). For
purposes of this Agreement, automotive-related businesses include automotive dealer financing;
automotive consumer financing and automotive leasing. GM will not have the right to terminate this
Agreement pursuant to this Section 5.2(d) for any of Licensee’s other businesses including the
insurance, mortgage, banking, or full-service leasing businesses. GM’s right to terminate this
Agreement pursuant to this Section 5.2(d) is further limited to only those countries or, in the
case of the United States, areas within the country, as specified in the applicable Service
Agreement, where exclusivity has been lost.

Section 5.3 Termination by a GM Subsidiary. Termination of this Agreement by General
Motors Corporation will also constitute termination on behalf of any and all GM Subsidiaries who
may have executed an Opt-in Letter. Termination of this Agreement by one or more GM Subsidiaries,
however, will only constitute termination with respect to those particular GM Subsidiaries, and not
constitute a termination on behalf of General Motors Corporation or any other GM Subsidiary.

Section 5.4 Termination of the Service Agreements. This Agreement terminates automatically
upon expiration or termination of all of the Services Agreements.

Section 5.5 Effect of Expiration or Termination.

          Upon the expiration or termination of this Agreement:

          (a) all licenses and sublicenses granted under or pursuant to this Agreement will
automatically terminate;

          (b) (i) if the termination is pursuant to paragraph (b) or (c) of Section 5.2, then each party
agrees to, and will ensure that its sublicensees, discontinue using the trademarks and other
intellectual property of the other party within a commercially reasonable time, not to exceed 180
days; provided, however, that a party will not unreasonably refuse to grant additional

12

 

           time to the extent any delays were caused by Governmental Authorities; provided further,
however, that if termination pursuant to paragraph (b) of section 5.2 is for breach of paragraph
b(ii) of this Section 5.5, each party agrees to, and will ensure that its sublicensees, discontinue
using the trademarks and other intellectual property of the other party within a commercially
reasonable time, not to exceed 90 days.

               (ii) other than a termination pursuant to paragraph (b) or (c) of Section 5.2 as provided
above, then each party agrees to, and will ensure that its sublicensees, discontinue using the
trademarks and other intellectual property of the other party within a commercially reasonable
time, not to exceed 90 days; provided, however, that a party will not unreasonably refuse to grant
additional time to remove their trademarks which were displayed in a manner reasonably requiring
additional time for removal such as, for example, on buildings and outdoor signs or to the extent
the delays were caused by Governmental Authorities;

          (c) Licensee agrees and will ensure that it and its sublicensees will amend their company name
registrations to remove the GM Trademarks therefrom; and

          (d) the parties agree, and will ensure that its sublicensees, abandon or assign to the other
party, at the other party’s election, any internet domain names comprising the other party’s
trademark, in whole or in part; provided, however, that if such internet domain name also includes
the trademark of another party, it will not be assigned but must be abandoned.

Notwithstanding the time provisions of paragraph 5.5(b) above, in connection with any GMAC real
estate franchise agreements entered into prior to the date hereof that have not been amended,
renewed, or extended during the term of this Agreement, the time period within which the
franchisees must discontinue use of the GMAC name and logo is extended to twelve months from the
expiration or termination of this Agreement. In all other respects, the provisions of paragraph
5.5(b) continue to apply.

Section 5.6 Injunctive Relief. The parties recognize that the nature of the damage caused
to the other party by the continued unauthorized use of the other party’s trademarks or other
intellectual property and would entitle the other party to the entry of an injunction by any court
of competent jurisdiction against such continued unauthorized use of its trademarks or other
intellectual property, and the parties therefore consent to such an injunction.

ARTICLE VI

INFRINGEMENT

Section 6.1 Each party has the sole right to take legal action against third parties who are
infringing upon its rights in its respective trademarks or other intellectual property and retain
any amount received from the infringing party pursuant to a corresponding settlement agreement
(less, in the case of GM, any amounts attributable to such legal action which Licensee has
reimbursed GM in accordance with Section 4.4 of this Agreement); provided, however, that, should GM
elect not to take legal action against a third party infringing the GMAC name or logo, Licensee
will be entitled to take such action, at its own expense and to retain any resulting settlement
recovery.

13

 

Section 6.2 In connection with any legal action commenced by Licensee concerning the GMAC name and
logo pursuant to Section 6.1 herein, it will not take any legal position or enter into any
settlement agreement that would be reasonably expected to adversely impact GM and, in particular,
the rights of GM in and to the GMAC name and logo. GM agrees to cooperate with Licensee, at
Licensee’s expense, in connection with Licensee’s pursuit of such legal action.

ARTICLE VII

party or by which it is bound.

          (e) There are no actions, suits, proceedings or other litigation or governmental investigation
pending or, to its knowledge, threatened, by or against it with respect to this Agreement or in
connection with the Dealings contemplated by this Agreement.

          (f) There is no order, injunction, or decree outstanding against, or relating to, it that
could reasonably be expected to have a material adverse effect upon its ability to perform its
obligations under this Agreement.

ARTICLE VIII

LIABILITY

Section 8.1 Liability. Each party will be liable in contract for the breach of its, and
its sublicensees’, obligations, covenants, and agreements under this Agreement, but will not be
liable to the other party: (i) under tort, except for gross negligence or willful misconduct; (ii)
under equity; or (iii) for claims arising out of any contract with any customer, dealer, or other
third party or otherwise in connection with their relationship with such Persons. Notwithstanding
anything to the contrary in this Agreement, during the 12 month period immediately following the
commencement of the Term of this Agreement (“Grace Period”), Licensee will:

          (a) conduct a commercially reasonable survey of existing third- party licensing and
sublicensing arrangements to determine whether the third party’s use of the sublicensed trademark
and performance under such arrangements comply with the terms of such existing license and
sublicense arrangements (“Third Party Noncompliance”); and

          (b) take commercially reasonable measures in consultation with GM to rectify any discovered
material Third Party Noncompliance, including consulting with the subject sublicensee, sending
“cease and desist” notices, and litigation, as appropriate.

          Licensee will not be liable in any respect for noncompliance by sublicensees (excluding
Subsidiaries) that occurred at any time before the end of the Grace Period. To the extent that
noncompliance by a particular sublicensee (excluding a Subsidiary) began before the end of the
Grace Period and continues thereafter, Licensee will not be liable in any respect for those
instances of noncompliance provided that Licensee sent a cease and desist notice, or initiated
litigation, arbitration, or other judicial or quasi judicial enforcement action against such
sublicensee before the end of the Grace Period and for so long as Licensee continues to use
commercially reasonable means to diligently prosecute enforcement actions to secure their
compliance, including with respect to cases where only a cease and desist notice was sent during
the Grace Period, initiating litigation, arbitration, or other judicial or quasi judicial
enforcement action at the appropriate time.

Section 8.2 Limitation of Damages. Neither party is liable under Section 8.1 for any
incidental, consequential, or non-economic damages.

Section 8.3 Equitable Remedies Permitted. Nothing in this Section limits or restricts
either party’s ability to seek equitable remedies, including specific performance.

Section 8.4 GM’s Indemnification of Licensee. Notwithstanding anything to the contrary
herein contained, GM agrees to indemnify and hold harmless Licensee, its officers, directors,
agents and employees from and against any and all claims, demands, obligations, causes of action
and lawsuits and all damages, liabilities, fines, judgments, costs (including settlement costs),
and expenses associated therewith (including the payment of reasonable attorney fees and
disbursements), arising out of a claim that Licensee’s use of the GM PROTECTION PLAN, GM MOTOR CLUB
and the SATURN SERVICE PLAN names and logos as authorized under this Agreement infringes the
trademark or other intellectual property rights of any third party;

15

 

provided that (i) prompt written notice is given to GM of any such claim or suit, (ii) GM will have
the option and right to undertake and conduct the defense of such claim or suit, (iii) and Licensee
cooperates fully in all respects with GM in the conduct and defense of such claim or suit and
proceedings related thereto. Licensee may, at its own expense, appear in any such action through
counsel of its own choosing.

ARTICLE IX

MISCELLANEOUS

Section 9.1 Successors and Assigns. This Agreement binds and inures to the benefit of the
parties hereto and their respective successors and assigns. Neither party may assign, delegate, or
otherwise transfer any of its rights or obligations under the Agreement, by operation of law or
otherwise, to any party other than one of its Subsidiaries without the consent of the other party
hereto, which consent will not be unreasonably withheld; provided that any assignment or transfer
to any Subsidiary will not relieve any party of its obligations under this Agreement.

Section 9.2 Waiver. The failure of any party to insist, in any one or more instances, upon
the performance of any of the terms, covenants, or conditions of this Agreement or to exercise any
right hereunder, will not operate or be construed as a waiver of any default, right, or remedy or
of that party’s right to insist upon strict compliance in the future. No waiver of any term,
condition or other provision of this Agreement is effective against a party unless acknowledged by
such party in writing.

Section 9.3 Unenforceability. If a court of competent jurisdiction holds any one or more
of the provisions of this Agreement to be unenforceable, such unenforceability will not affect any
other provision. In such event, the parties will substitute a provision that is as close as
possible to the intent of the original unenforceable provisions.

Section 9.4 Headings. Headings used in this Agreement are for reference purposes only and
will not be deemed a part of this Agreement or used in the interpretations of the substantive
provisions of it.

Section 9.5 Governing Law. This Agreement is governed by, and construed and enforced in
accordance with the laws of the State of New York, excluding any conflict of law provisions which
would require application of any other law.

Section 9.6 Dispute Resolution.

          (a) Any dispute, controversy, claim or disagreement arising from or in connection with this
Agreement (“Dispute”), will be exclusively governed by and resolved in accordance with the
provisions of this Section 9.6. The parties will use reasonable efforts to settle all Disputes
before resorting to litigation.

          (b) Any Dispute which cannot be resolved at the working level will immediately be escalated
to the Licensee President Auto Finance and the GM Treasurer, or their designees for the particular
matter, for resolution.

16

 

          (c) Any Dispute under this Agreement which is not resolved by the Licensee President Auto

not resolved within 90 days of the date of escalation to the Licensee Auto Finance President and GM
Treasurer, either party may pursue legal remedies.

          (d) Each party agrees that any suit, action or proceeding against the other party arising out
of or relating to this Agreement or any transaction contemplated hereby may only be brought in any
federal or state court located in the city, county and State of New York, and each party hereby
submits to the exclusive jurisdiction of such courts for the purpose of any such suit, action or
proceeding. Each party further agrees that service of any process, summons, notice or document by
U.S. registered mail to such party’s respective address set forth in this Agreement for notice is
effective service of process for any action, suit or proceeding in the State of New York with
respect to any matters to which it has submitted to jurisdiction in this Section. EACH OF THE
PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          (e) This Section 9.6 does not limit either party’s right to apply to a court of the State of
New York for equitable, provisional relief with respect to any Dispute pending the resolution of
the Dispute pursuant to this Section 9.6.

Section 9.7 Entire Agreement. This Agreement, including the Exhibits attached hereto,
constitutes the entire agreement between Licensee and GM with respect to the subject matter of this
Agreement and, except to the extent otherwise contemplated by this Agreement, supersedes all
previous oral and written agreements, proposals, negotiations, representations, commitments and
other communications among the parties with respect to its subject matter.

Section 9.8 Amendments. This Agreement may not be revised, discharged, altered, amended,
modified, or renewed except by a writing signed by duly authorized representatives of the parties.

Section 9.9 Counterparts. This Agreement may be executed simultaneously in one or more
counterparts, each of which is deemed an original and all of which together constitute one and the
same instrument.

     The provisions above governing the date on which a notice is deemed to have been received by a
party means and refers to the date on which a party, and not its counsel or other recipient to
which a copy of the notice may be sent, is deemed to have received the notice.

     If a notice is tendered pursuant to the provisions of this Agreement and is refused by the
intended recipient, the notice will nonetheless be deemed to have been given and is effective as of
the date provided in this Agreement.

     In any event, any notice given to a party in a manner other than that provided in this
Agreement that the party actually receives, is effective with respect to the party on receipt.

Section 9.11 Relationship of Parties. Nothing contained in this Agreement will be
construed as creating a joint venture, association, partnership, franchise, or agency relationship,
and nothing contained in this Agreement will be construed as making a party liable for the debts or
obligations of the other party, unless expressly provided in this Agreement or another agreement.

     IN WITNESS WHEREOF, the parties hereto by their duly authorized representatives have executed
this Agreement effective as of the date first above written.
