         POOLING AND SERVICING AGREEMENT, dated as of December 1, 2003, among
MERRILL LYNCH MORTGAGE INVESTORS, INC., a Delaware corporation, as depositor
(the "Depositor"), LITTON LOAN SERVICING LP, a Delaware limited partnership, as
servicer (the "Servicer") and JPMORGAN CHASE BANK, a New York banking
corporation, 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) two real estate mortgage investment conduits,
(ii) the right to receive (x) prepayment penalties on the Mortgage Loans, (y)
amounts paid by the Servicer or the Seller in respect of prepayment charges or
waivers thereof pursuant to this Agreement and (z) amounts received in respect
of any indemnification paid as a result of a prepayment charge being
unenforceable in breach of the representations and warranties set forth in the
Sale Agreement and (iii) the grantor trusts described in Section 2.07 hereof.
The Lower Tier REMIC will consist of all of the assets constituting the Trust
Fund (other than the assets described in clauses (ii) and (iii) above, the Lower
Tier REMIC Regular Interests and the Uncertificated Class C Interest) 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 LT-R 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 LT-R 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 Seller 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

          CONVEYANCE OF MORTGAGE LOANS; REPRESENTATIONS AND WARRANTIES

         SECTION 2.01. Conveyance of Mortgage Loans.

         The Depositor, concurrently with the execution and delivery hereof,

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)      The Original Mortgage Note endorsed, "Pay to the order of
JPMorgan Chase Bank, as trustee - SURF 2003-BC4, without recourse" together with

language indicating that the Mortgage Loan is a MOM Loan or if the Mortgage Loan
was not a MOM Loan at origination, the original Mortgage and the assignment
thereof to MERS, with evidence of recording indicated thereon, or a copy of the
Mortgage certified by the public recording office in which such Mortgage has
been recorded.

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

                                       44
<PAGE>

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

         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 an Assignment of
Mortgage is not recorded, the Servicer shall have no liability for its failure
to receive and act on notices related to such Assignment of Mortgage.

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

                                       45
<PAGE>

         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 Seller contained in the
Sale Agreement to take, at the request of the Depositor or the Trustee, all
action on its part which is reasonably necessary to ensure the enforceability of
a Mortgage Loan. The Trustee hereby accepts such assignment, and shall be
entitled to exercise all rights of the Depositor under the Sale Agreement as if,
for such purpose, it were the Depositor. The foregoing sale, transfer,
assignment, set-over, deposit and conveyance does not and is not intended to
result in creation or assumption by the Trustee of any obligation of the
Depositor, the Seller, or any other Person in connection with the Mortgage Loans
or any other agreement or instrument relating thereto.

         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 Seller to repurchase
any Mortgage Loan to which a material exception was taken in the Exception
Report unless such exception is cured to the satisfaction of the Trustee within
45 Business Days of the Closing Date.

         The Trustee acknowledges receipt of the Transfer Agreement and the Sale
Agreement.

         The Trustee agrees, for the benefit of Certificateholders and the NIMs
Insurer, to review each Mortgage File delivered to it within 60 days after the
Closing Date to ascertain and to certify, within 70 days of the Closing Date, to
the NIMs Insurer, the Depositor and the Servicer that all documents required by
Section 2.01 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 Servicer, the
Seller, the Depositor and the NIMs Insurer. In addition, the Trustee shall also
notify the Servicer, the Seller, the Depositor and the NIMs Insurer, if the
original Mortgage with evidence of recording thereon with respect to a Mortgage
Loan is not received within 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 officer for recordation
and thereafter the Depositor shall deliver or cause to be delivered such
Mortgage with evidence of recording thereon upon receipt thereof from the public
recording office. The Trustee shall request that the Seller correct or cure such
omission, defect or other irregularity, or substitute a Mortgage Loan pursuant
to the provisions of Section 2.03(c), within 90 days from the date the Seller
was notified of such omission or defect and, if the Seller does not correct or
cure such omission or defect within such period, that the Seller purchase such
Mortgage Loan from the Trust Fund within 90 days from the date the Trustee
notified the Seller of such omission, defect or other irregularity at the
Purchase Price of such Mortgage Loan. The Purchase Price for any Mortgage Loan
purchased pursuant to this Section 2.02 shall be paid to the Servicer and
deposited by the Servicer in the 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 Seller the related Mortgage File and the Trustee shall
execute and deliver such instruments

                                       46

of transfer or assignment, without recourse, representation or warranty, as
shall be necessary to vest in the Seller or its designee, as the case may be,
any Mortgage Loan released pursuant hereto, and the Trustee shall have no
further responsibility with regard to such Mortgage Loan. It is understood and
agreed that the obligation of the Seller to purchase, cure or substitute any
Mortgage Loan as to which a material defect in or omission of a constituent
document exists shall constitute the sole remedy respecting such defect or
omission available to the Trustee on behalf of Certificateholders and the NIMs
Insurer. The preceding sentence shall not, however, limit any remedies available
to the Certificateholders, the Depositor, the Trustee or the NIMs Insurer
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 70 days of the Closing Date, the Trustee shall deliver to the
Depositor, the Servicer and the NIMs Insurer the Trustee's Certification,
substantially in the form of Exhibit D attached hereto, evidencing the
completeness of the Mortgage Files, with any exceptions noted thereto.

         SECTION 2.03. Representations, Warranties and Covenants of the
Depositor.

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

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

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

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

                                       47
<PAGE>

         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 Seller,
         the Depositor had good title to the Mortgage Loans and the Mortgage
         Notes were subject to no offsets, claims, liens, mortgage, pledge,
         charge, security interest, defenses or counterclaims.

         (b)      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
Seller under the Sale Agreement, the only right or remedy of the Trustee, the
NIMs Insurer or of any Certificateholder shall be the Trustee's right to enforce
the obligations of the Seller 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 Depositor, the Servicer, the NIMs
Insurer, 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 90 days of the discovery of a breach of any
representation or warranty given to the Trustee by the Depositor, the Seller and
assigned to the Trustee, the Depositor, or the Seller shall either (a) cure such
breach in all material respects, (b) repurchase such Mortgage Loan or any
property acquired in respect thereof from the Trustee at the Purchase Price or
(c) within the two year period following the Closing Date, substitute a
Replacement Mortgage Loan for the affected Mortgage Loan. In the event of
discovery of a breach of any representation and warranty of the Seller or the
Depositor, the Trustee shall enforce its rights under the Sale Agreement or
thereunder for the benefit of Certificateholders and the NIMs Insurer. If a
breach of the representations and warranties set forth in the Sale Agreement
hereof exists solely due to the unenforceability of a prepayment charge, the
Trustee shall notify the NIMs Insurer thereof and not seek to enforce the
repurchase remedy provided for herein unless directed in writing to do so by 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 at the request of the NIMs Insurer enforce the right of the Trust Fund and
the NIMs Insurer 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 Seller substitutes for
a Mortgage Loan for which there is a breach of any representations and
warranties which adversely and materially affects

                                       48

<PAGE>

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 Seller
will, in exchange for such substitute Mortgage Loan, (i) provide the applicable
Purchase Price for the affected Mortgage Loan or (ii) within two years of the
Closing Date, substitute such affected Mortgage Loan with a Replacement Mortgage
Loan. Any such substitution shall not be effected prior to the additional
delivery to the Trustee of a Request for Release substantially in the form of
Exhibit I and shall not be effected unless it is within two years of the Startup
Date. As provided in the Sale Agreement, the Seller indemnifies and holds the
Trust Fund, the Trustee, the Depositor, the NIMs Insurer, the Servicer and each
Certificateholder harmless against any and all taxes, claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and any
other costs, fees and expenses that the Trust Fund, the Trustee, the Depositor,
the NIMs Insurer, the Servicer and any Certificateholder may sustain in
connection with any actions of the Seller 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 Trust Fund 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 date"
under Section 860(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 Seller 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 Seller, 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 Seller, 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 NIMs Insurer and
the Depositor that all documents required by Section 2.01 have been executed and
received.

         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Seller 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 penalties 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 penalties 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 Seller to the
Servicer for deposit into the Collection

                                       49

<PAGE>

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 Seller shall give or cause to be given written notice to the
Certificateholders and the NIMs Insurer 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 Seller, such Replacement Mortgage Loan or Replacement
Mortgage Loans shall constitute part of the Mortgage Pool and shall be subject
in all respects to the terms of this Agreement and the Sale Agreement, including
all applicable representations and warranties thereof included in the Sale
Agreement as of the date of substitution.

         In addition, the Seller shall obtain at its own expense and deliver to
the Trustee and the NIMs Insurer an Opinion of Counsel addressed to the Trustee
and the NIMs Insurer to the effect that such substitution will not (a) cause any
federal tax to be imposed on the Trust Fund 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 date" 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 Seller 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.

         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

         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 service the Mortgage Loans in

         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

         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

         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

         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

         under this Agreement in accordance with the terms hereof.

         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 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 (1) 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 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,

                                       51

<PAGE>

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 Trustee
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 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 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 Date" for purposes of the REMIC Provisions shall be
the Closing Date. Each REMIC's fiscal year shall be the calendar year.

         The Lower Tier REMIC shall consist of all of the assets of the Trust
Fund (other than (i) any proceeds of prepayment penalties, (ii) amounts paid by
the Servicer or the Seller in respect of prepayment charges or waivers thereof
pursuant to this Agreement, (iii) amounts received in respect of any
indemnification paid as a result of a prepayment charge being unenforceable in
breach of the representations and warranties set forth in the Sale Agreement,
(iv) the interests issued by the REMICs provided for herein and (v) the grantor
trusts described in this Section 2.07. The Lower Tier REMIC shall issue (i) the
Lower Tier REMIC Regular Interests, each of which shall be designated as regular
interests of such REMIC, and (ii) the Class LT-R Interest that shall be
designated as the sole class of residual interest in REMIC 1. Each of the Lower
Tier REMIC Regular Interests shall have the characteristics set forth in its
definition and in this Section 2.07.

         The Class LT-R Interest shall have neither an interest rate nor a
principal amount. The Class LT-1A Interest shall have an initial principal
balance equal to 0.01% of the excess of the Stated Principal Balance of the
Group One Mortgage Loans as of the Cut-off Date over the aggregate initial
Certificate Principal Balance of the Class A-1 and Class R Certificates and
shall bear interest at the Net Rate. The Class LT-1B shall have an initial
principal balance equal to 0.01% of the Stated Principal Balance of the Group
One Mortgage Loans as of the Cut-off Date. The Class LT-2A Interest shall have
an initial principal balance equal to 0.01% of the excess of the Stated
Principal Balance of the Group Two Mortgage Loans as of the Cut-off Date over
the aggregate initial Certificate Principal Balance of the Class A-2
Certificates and shall bear interest at the Net Rate. The Class LT-2B shall have
an initial principal balance equal to 0.01% of the Stated Principal Balance of
the Group Two Mortgage Loans as of the Cut-off Date. The Class LT-3A Interest
shall have an initial principal balance equal to 0.01% of the excess of the
Stated Principal Balance of the Group Three Mortgage Loans as of the Cut-off
Date over the aggregate Certificate Principal Balance of the Class A-3A and
Class A-3B Certificates and shall bear interest at the Net Rate. The Class LT-3B
shall have an initial principal balance equal to 0.01% of the

                                       52

<PAGE>

Stated Principal Balance of the Group Three Mortgage Loans as of the Cut-off
Date. The Class LT-X Interest shall have an initial principal balance equal to
the excess of 50% of the initial aggregate Stated Principal Balance of the
Mortgage Loans over the initial aggregate principal balance of the Lower Tier
REMIC A Interests and the Lower Tier REMIC B Interests.

         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.

         The beneficial ownership of the Class LT-R Interest and the Residual
Interest shall be represented by the Class R Certificate.

         All calculations with respect to the Lower Tier REMIC Interests shall
be taken out to eight decimal places.

         (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 a 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)      It is intended that the rights of the Class A-1 Certificates,
Class A-2 Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates Class B-1 Certificates Class B-2
Certificates and Class B-3 Certificates to receive payments in respect of
Floating Rate Certificate Carryovers 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-1 Certificates, Class A-2 Certificates, Class R
Certificate, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class B-1 Certificates, Class B-2 Certificates and Class B-3
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-1 Certificates, Class A-2 Certificates, M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates Class B-1 Certificates, Class B-2
Certificates and Class B-3 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-1 Certificates,
Class A-2 Certificates, Class R Certificate, M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates or Class B-3 Certificates receive payments in respect of Floating
Rate Certificate Carryovers, 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 relevant Class of Certificates
pursuant to the related interest cap agreement.

         (e)      The parties intend that the portion of the Trust Fund
consisting of the Uncertificated Class C Interest, and the obligation of the
holders of the Class C Certificates to pay amounts in respect of Floating Rate
Certificate Carryovers, to the holders of the Class A-1 Certificates, Class A-2
Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates shall be treated as a "grantor trust"
under the Code, 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

                                       53

<PAGE>

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-1 Certificates, Class A-2 Certificates, Class R Certificate,
Class M-1 Certificates, Class M-2 Certificates, Class M-3 Certificates, Class
B-1 Certificates, Class B-2 Certificates, Class B-3 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 proceeds from prepayment penalties collected
on the Mortgage Loans, amounts paid by the Servicer or Seller in respect of
prepayment charges pursuant to this Agreement and amounts received with respect
to any amounts in respect of any indemnification paid as a result of a
prepayment charge being unenforceable in breach of the representations and
warranties set forth in the Sale Agreement shall be treated as a "grantor trust"
under the Code, 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 the portion of the Trust Fund
consisting of the Class R Certificate and the right of the Class C Certificates
to receive the amounts described in the last paragraph of Section 9.01 hereof
shall be treated as a "grantor trust" under the Code and the provisions hereof
shall be interpreted consistent with this intention. In furtherance of this
intention, the Trustee shall (i) furnish or cause to be furnished to the holders
of the Class R Certificate and the Class C Certificates information regarding
their allocable share 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 as may be applicable under the Code.

         An amount equal to 50% of all payments of principal and interest on the
Mortgage Loans shall be distributed in respect of the Lower Tier REMIC Side One
Interests. All such payments of principal and interest on the Mortgage Loans
shall be paid to the Lower Tier REMIC Side One 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 LT-R Interest. On each Distribution Date, an amount equal to 25% of
the increase in the Overcollateralization Amount shall be payable as a reduction
of the principal amounts of the Lower Tier REMIC Marker Classes (with such
amount allocated among the Lower Tier REMIC Marker Classes so that each Lower
Tier REMIC Marker Class will have its principal reduced by an amount equal to
25% of any increase in the Overcollateralization Amount that results in a
reduction in the principal balance of its Corresponding Certificate) and will be
accrued and added to the principal balance of the Class LT1-Z Interest. All
payments of principal on the Mortgage Loans allocated to the Lower Tier REMIC
Side One Interests shall be allocated 50% to the Class LT-Z Interest and 50% to
the Lower Tier REMIC Marker Classes (with principal payments allocated to each
of the Lower Tier REMIC Marker Classes in an amount equal to 25% of the
principal amounts distributed to the Corresponding Certificates in reduction of
their principal amounts). Notwithstanding the preceding sentence, an amount
equal to 50% of the principal payments that result in a reduction in the
Overcollateralization Amount shall be treated as payable entirely to the Class
LT1-Z Interest. Fifty percent of Realized Losses with respect to principal on
the Mortgage Loans shall be allocated to the Lower Tier REMIC Side One Interests
and applied to the Lower REMIC Marker Classes and the Class LT1-Z Interest in
such a way that, after all distributions have been made on each Distribution
Date, (i) the principal balance of each of the Lower Tier REMIC Marker Classes
is equal to 25% of the principal balance of the Corresponding Certificates and
(ii) the principal balance of the Class

                                       54

<PAGE>

LT1-Z Interest is equal to the sum of (x) 25% of the aggregate Stated Principal
Balance of the Mortgage Loans as of such Distribution Date and (y) 25% of the
Overcollateralization Amount. Each Lower Tier REMIC Marker Class shall be
entitled to receive an amount equal to 25% of all amounts distributed to the
Corresponding Certificates in respect of unreimbursed amounts of Realized
Losses. The Class LT1-Z Interest shall be entitled to receive the excess of 50%
of all amounts distributed to the Certificates in respect of unreimbursed
amounts of Realized Losses over the amounts allocated pursuant to the preceding
sentence.

         An amount equal to 50% of all payments of principal and interest on the
Mortgage Loans shall be distributed in respect of the Lower Tier REMIC Side Two
Interests. Such principal distributions shall be deemed made on the Lower Tier
REMIC Side Two Interests first, so as to keep the uncertificated principal
balance of each lower Tier REMIC Side Two Interest ending with the designation
"A" equal to 0.01% of the excess of (i) the aggregate Stated Principal Balance
of the Mortgage Loans in the related Mortgage Group (with the Class LT-1A
Interest related to Group One, the Class LT-2A Interest related to Group Two and
the Class LT-3A Interest related to Group Three) over (ii) the aggregate Class
Principal Amounts of the Certificates in the Certificate Group related to such
Mortgage Group (except that if 0.01% of any such excess is greater than the
principal amount of the corresponding Lower Tier REMIC A Interest, the least
amount of principal shall be allocated to the Lower Tier REMIC A Interests such
that the Lower Tier REMIC Subordinated Balance Ratio is maintained); second, to
each of the Lower Tier REMIC B Interests so as to keep the uncertificated
principal balance of each Lower Tier REMIC B Interest equal to 0.01% of the
aggregate Stated Principal Balance of the Mortgage Loans in the related Mortgage
Group (with the Class LT-1B Interest related to Group One, the Class LT-2B
Interest related to Group Two and the Class LT-3B Interest related to Group
Three) and finally, all of the remaining portion of such principal to the Class
LT-X Interest. Fifty percent of all Realized Losses with respect to the Mortgage
Loans shall be applied to the Lower Tier REMIC Side Two Interests and such
Realized Losses with respect to principal shall be allocated to the Lower Tier
REMIC Side Two Interests first, so as to keep the uncertificated principal
balance of each lower Tier REMIC Side Two Interest ending with the designation
"A" equal to 0.01% of the excess of (i) the aggregate Stated Principal Balance
of the Mortgage Loans in the related Mortgage Group (with the Class LT-1A
Interest related to Group One, the Class LT-2A Interest related to Group Two and
the Class LT-3A Interest related to Group Three) over (ii) the aggregate Class
Principal Amounts of the Certificates in the Certificate Group related to such
Mortgage Group (except that if 0.01% of any such excess is greater than the
principal amount of the corresponding Lower Tier REMIC A Interest, the least
amount of Realized Losses shall be allocated to the Lower Tier REMIC A Interests
such that the Lower Tier REMIC Subordinated Balance Ratio is maintained);
second, to each of the Lower Tier REMIC B Interests so as to keep the
uncertificated principal balance of each Lower Tier REMIC B Interest equal to
0.01% of the aggregate Stated Principal Balance of the Mortgage Loans in the
related Mortgage Group (with the Class LT-1B Interest related to Group One, the
Class LT-2B Interest related to Group Two and the Class LT-3B Interest related
to Group Three) and finally, all of the remaining portion of such Realized
Losses to the Class LT-X Interest.

         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 Trust Fund against any and all Losses resulting from such
negligence; provided, however, that the Servicer shall not be liable for any
such Losses attributable to the action or inaction of the Trustee, the Depositor
or the Holder of the 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

                                       55

<PAGE>

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 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).

         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 Trust Fund 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 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 as follows:

         (a)      the Servicer shall comply in the performance of its
obligations under this Agreement with all reasonable rules and requirements of
the insurer under each Required Insurance Policy;

         (b)      no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, the Trustee
or the NIMs Insurer, any affiliate of the Depositor, the Trustee or the NIMs
Insurer and prepared by the Servicer pursuant to this Agreement will be
inaccurate in any material respect, provided, however, that the Servicer shall
not be responsible for inaccurate information provided to it by third parties.

         SECTION 2.09. [RESERVED].

         SECTION 2.10. [RESERVED].

         SECTION 2.11. Permitted Activities of the Trust. The Trust is created
for the object and purpose of engaging in the Permitted Activities. In
furtherance of the foregoing, the Trustee is hereby authorized and directed to
execute and deliver on behalf of the Trust, and to perform the duties and
obligations of the Trustee under, an insurance and indemnity agreement with a
NIMs Insurer and any other agreement or instrument related thereto, in each case
in such form as the Depositor shall direct or shall approve, the execution and
delivery of any such agreement by the Depositor to be conclusive evidence of its
approval thereof.

         SECTION 2.12. Qualification Special Purpose Entity. For purposes of
SFAS 140, the parties hereto intend that the Trust Fund shall be treated as a
"qualifying special purpose entity" as such term is used in SFAS 140 and any
successor rule thereto and its power and authority as stated in Section 2.11 of
this Agreement shall be limited in accordance with paragraph 35 of SFAS 140.

                                   ARTICLE III
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

         SECTION 3.01. Servicer to Service Mortgage Loans.

         For and on behalf of the Certificateholders, the Servicer shall service
and administer the Mortgage Loans in accordance with Accepted Servicing
Practices. In connection with such servicing and administration, the Servicer
shall have full power and authority, acting alone and/or through subservicers as
provided in Section 3.02 hereof, to do or cause to be done any and all things
that it may deem necessary or desirable in connection with such servicing and
administration, including but not limited to, the power and authority, subject
to the terms hereof (i) to execute and deliver, on behalf of the
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 Trust Fund 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 Trust Fund in
the same manner as it currently protects its own interest in mortgage loans in
its own portfolio in any claim, proceeding or litigation regarding a Mortgage
Loan, but in any case not in any manner that is a lesser standard than that
provided in the first sentence of this Section 3.01. 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, or of partial or full release or
discharge 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

                                       57

<PAGE>

reasonably required by the Servicer, the Trustee shall furnish the Servicer
with a power 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 and shall be indemnified by the Servicer for any costs,
liabilities or expenses incurred by the Trustee in connection therewith.

         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 the 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 the 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 the 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. All costs incurred by the Servicer, if any, in effecting the
timely payments 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 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 that 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.

         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. 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

                                       58

<PAGE>

with the consent of the NIMs Insurer 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 NIMs Insurer and the Trustee copies of all subservicing
agreements.

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

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

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

         SECTION 3.04. Trustee to Act as Servicer.

         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 or 2.03 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 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 Trust Fund for any such expense incurred by the Trust Fund upon receipt of a
reasonably detailed invoice evidencing such expenses. If the Trustee is
unwilling or unable to act as servicer, or if the NIMs Insurer so directs the
Trustee, the Trustee shall seek to appoint a successor servicer that is eligible
in accordance with the criteria specified 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

                                       59

<PAGE>

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 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.

         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 penalty 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 since the Cutoff 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 penalty 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 voluntary sale of the related
Mortgaged Property, or (iv) in the Servicer's reasonable judgment as

                                       60

described in Section 3.01 hereof, (x) such waiver relates to a default or a
reasonably foreseeable default, (y) such waiver would maximize recovery of total
proceeds taking into account the value of such prepayment penalty and related
Mortgage Loan and (z) doing so is standard and customary in servicing similar
Mortgage Loans (including any waiver of a prepayment penalty in connection with
a refinancing of a Mortgage Loan that is related to a default or a reasonably
foreseeable default). Except as provided in the preceding sentence, in no event
will the Servicer waive a prepayment penalty in connection with a refinancing of
a Mortgage Loan that is not related to a default or a reasonably foreseeable
default. If the Servicer waives or does not collect all or a portion of a
prepayment penalty 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 penalty (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 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 the Mortgagor in accordance with the Servicer's normal
         servicing procedures;

                  (iv)     all Compensating Interest;

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

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

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

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

                  (ix)     all prepayment penalties; and

                                       61

<PAGE>

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

         The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, late payment charges,
insufficient funds charges and payments in the nature of assumption fees (i.e.
fees related to the assumption of a Mortgage Loan upon the purchase of the
related Mortgaged Property) and other similar ancillary fees (other than
prepayment penalties) 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.

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

         (e)      [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 3:00 p.m. New York City
time (or such earlier deadline for investment in the Permitted Investments
designated by the Trustee) which are required to be deposited in the Certificate
Account by the Servicer shall 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. The Trustee shall give notice to the NIMs

                                       62
<PAGE>

Insurer and the Servicer of the location of the Certificate Account maintained
by it when established and prior to any change thereof.

         (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
remitted to it monthly as provided herein. The amount of any losses incurred in
the Collection Account in respect of any such investments shall be deposited by
the Servicer in the Collection Account out of the Servicer's own funds
immediately as realized. All income and gain net of any losses realized from
amounts on deposit in the Certificate Account shall be for the benefit of the
Trustee and shall be remitted to or withdrawn by it monthly as provided herein.
The amount of any losses incurred in the Certificate Account in respect of any
such investments shall be deposited by the Trustee, in the Certificate Account
out of the Trustee's own funds immediately as realized.

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

         To the extent required by the related Mortgage Note, the Servicer shall
establish and maintain one or more accounts (each, an "Escrow Account") and
deposit and retain therein all collections from the Mortgagors (or advances by
the Servicer) for the payment of taxes, assessments, hazard insurance premiums
or comparable items for the account of the Mortgagors. Nothing herein shall
require the Servicer to compel a Mortgagor to establish an Escrow Account in
violation of applicable law.

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

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

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

                                       63
<PAGE>

entitled to be reimbursed by each such Certificateholder for actual expenses
incurred by the Servicer in providing such reports and access.

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

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

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

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

                  (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)     pay 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) 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 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;

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

                  (ix)     to reimburse the Trustee for enforcement expenses
         reasonably incurred in respect of a breach of 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

                                       64
<PAGE>

         subclause (ix) only to the that such expenses would constitute
         "unanticipated expenses" within the meaning of Treasury Regulation
         Section 1.860G-1 (b)(3)(ii) if paid by one of the REMICs provided for
         herein;

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

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

         In addition, no later than 3:00 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, to the extent on deposit,
and such amount shall be deposited in the Certificate Account; provided, however
if the Trustee does not receive such Interest Funds and Principal Funds by 4:00
p.m. Eastern Time, such Interest Funds and Principal Funds shall be deposited in
the Certificate Account on the next Business Day.

         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 and the
NIMs Insurer 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 P&I 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;

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

                  (v)      to pay to the Credit Risk Manager, the Credit Risk
         Manager Fee.

<PAGE>

         SECTION 3.09. [RESERVED].

         SECTION 3.10. Maintenance of Hazard Insurance.

         The Servicer shall cause to be maintained, for each Mortgage Loan,
hazard insurance with extended coverage in an amount that is at least equal to
the lesser of (i) the replacement value of the improvements that are part of
such Mortgaged Property and (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. 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 the 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 original principal balance of the related Mortgage Loan, (ii) the
replacement value of the improvements that are part of such Mortgaged Property,
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, enforce any due-on-sale clause contained in 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

                                       66
<PAGE>

right if the due-on-sale clause, in the reasonable belief of the Servicer, is
not enforceable under applicable law. An opinion of counsel, which shall be
reimbursable as a Servicing Advance, delivered to the Trustee and the Depositor
to the foregoing shall conclusively establish the reasonableness of such belief
to the extent permitted under applicable law. Notwithstanding the foregoing, the
Servicer is not required to exercise such rights with respect to a Mortgage Loan
if the Person to whom the related Mortgaged Property has been conveyed or is
proposed to be conveyed satisfies the terms and conditions contained in the
Mortgage Note and Mortgage related thereto and the consent of the mortgagee
under such Mortgage Note or Mortgage is not otherwise so required under such
Mortgage Note or Mortgage as a condition to such transfer. 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 state 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 penalty and any other term affecting
the amount or timing of payment on the Mortgage Loan) may be changed. The
Servicer shall notify the Trustee and the NIMs Insurer that any such
substitution or assumption agreement has been completed by forwarding to the
Trustee (with a copy to the NIMs Insurer) 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.

         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

                                       67
<PAGE>

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
increase the proceeds of liquidation of the Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Collection Account pursuant to Section 3.08
hereof). The Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided, however, that it shall be
entitled to reimbursement thereof from the proceeds of liquidation of the
related Mortgaged Property, as contemplated in Section 3.08 hereof. If the
Servicer has knowledge that a Mortgaged Property that the Servicer is
contemplating acquiring in foreclosure or by deed-in-lieu of foreclosure is
located within a one-mile radius of any site with environmental or hazardous
waste risks known to the Servicer, the Servicer will, prior to acquiring the
Mortgaged Property, consider such risks and only take action in accordance with
Accepted Servicing Practices.

         With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the Trustee or its nominee. Pursuant to its efforts to
sell such REO Property, the Servicer shall either itself or through an agent
selected by the Servicer protect and conserve such REO Property in the same
manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Servicer deems to be in the best interest of the Servicer and the
Certificateholders for the period prior to the sale of such REO Property. The
Servicer or an affiliate 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 Trust Fund 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
Trust Fund or, at the expense of the Trust Fund, request more than 60 days prior
to the day on which such three-year period would otherwise expire, an extension
of the three-year grace period unless the Trustee and the NIMs Insurer shall
have been supplied with an Opinion of Counsel addressed to the Trustee and the
NIMs Insurer (such Opinion of Counsel not to be an expense of the Trustee or the
NIMs Insurer) to the effect that the holding by the Trust Fund of such Mortgaged
Property subsequent to such three-year period will not result in the imposition
of taxes on "prohibited transactions" of the Trust Fund 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 Trust Fund 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 Trust Fund shall be rented (or allowed to continue to
be rented) or otherwise used for the production of income by or on behalf of the
Trust Fund in such a manner or

                                       68
<PAGE>

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 Trust Fund 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
Trust Fund with respect to the imposition of any such taxes.

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

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

         The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds or any income from an REO
Property, will be applied in the following order of priority: first, to
reimburse the Servicer for any related unreimbursed Servicing Advances and
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 any prepayment penalties and then to
accrued and unpaid interest (to the extent no Advance has been made for such
amount) on the Mortgage Loan or related REO Property, at the Net Mortgage Rate
to the Due Date occurring in the month in which such amounts are required to be
distributed; and fourth, as a recovery of principal of the Mortgage Loan.

         (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 sent to the Trustee) to purchase for its own account
from the Trust Fund any Mortgage Loan that is 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 be delivered to the Trustee for deposit
in the Collection 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

                                       69
<PAGE>

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 which 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 40, 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 to purchase for its own account from the Trust Fund 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, 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
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 Collection 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
Litton Loan Servicing LP 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. No expenses incurred in connection
with any instrument of satisfaction or deed of reconveyance shall be chargeable
to the Collection Account, the Certificate Account or the related subservicing
account. 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, in
which case the Trustee or its designee shall deliver the Request for Release to
the Servicer.

         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 promptly release the related Mortgage File(s) within five
(5) Business Days of receipt of a properly completed Request for Release
pursuant to clauses (i), (ii) or (iii) above. Receipt of a properly completed
Request for Release shall be authorization to the Trustee or its 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 in a timely manner, 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.

         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 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

                                       70

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
of interest on a Mortgage Loan included in the Trust Fund an amount equal to
interest at the applicable Servicing Fee Rate on the Stated Principal Balance of
the related Mortgage Loan as of the immediately preceding Distribution Date.

         Additional servicing compensation in the form of any Excess Proceeds,
late payment fees, assumption fees (i.e. fees related to the assumption of a
Mortgage Loan upon the purchase of the related Mortgaged Property) and similar
fees payable by the Mortgagor, and all income and gain net of any losses
realized from Permitted Investments in the Collection Account shall be retained
by the Servicer to the extent not required to be deposited in the Collection
Account pursuant to Sections 3.05, or 3.12(a) 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.

         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

                                       71
<PAGE>

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.

         Pursuant to this Agreement, the Servicer shall deliver to the
Depositor, the Trustee and the NIMs insurer on or before February 28 beginning
in 2004 or such other date that the Depositor gives the Servicer at least 30
days prior notice of in order to remain in compliance with the Section 302
Requirements, an Officer's Certificate stating, as to each signatory thereof,

calendar year and of performance under this Agreement has been made under such
officer's supervision, and (ii) to the best of such officers' knowledge, based
on such review, the Servicer has fulfilled all of its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officers and the nature and status thereof. The Trustee shall forward a copy of
each such statement received by it to each Rating Agency. Copies of such
statement shall be provided by the Trustee to any Certificateholder upon written

         On or before March 15 of each year, beginning in 2004 or such other
date in order to remain in compliance with the Section 302 Requirements, the
Servicer at its expense shall cause a nationally recognized firm of independent
public accountants (who may also render other services to the Servicer or any
Affiliate thereof) that is a member of the American Institute of Certified
Public Accountants to furnish a USAP Report to the Trustee, the NIMs Insurer and
the Depositor. Copies of the USAP Report shall be provided by the Trustee to any
Certificateholder upon request at the Certificateholder's expense, provided such
report has been delivered by the Servicer to the Trustee. In addition, at the
NIMs Insurer's written request, the Servicer shall deliver copies of evidence of
the Servicer's fidelity bond or errors and omissions insurance coverage to the
NIMs Insurer.

         SECTION 3.19. Rights of the NIMs Insurer. Each of the rights of the
NIMs Insurer set forth in this agreement shall exist so long as the notes issued
pursuant to the Indenture remain outstanding or the NIMs Insurer is owed amounts
in respect of its guarantee of payment on such notes.

         SECTION 3.20. Periodic Filings.

         (a)      Promptly upon receipt of any report of the independent public
accountants required pursuant to Section 3.18, the Trustee shall review such

and any significant deficiencies relating to the Servicer's compliance set forth
in the report of the Servicer's certified independent accountants described

this Section. If permitted by applicable law and unless the Depositor otherwise

Fund. The Depositor agrees to promptly furnish to the Trustee, from time to time
upon request, such further information, reports, and financial statements within
its control related to this Agreement and the Mortgage Loans as the Trustee
reasonably deems appropriate to prepare and file all necessary reports with the
Commission. The Trustee shall have no responsibility to file any items other
than those specified in this section.

         (c)      [RESERVED].

         (d)      The obligations set forth in paragraphs (a) through (c) of

amount paid or payable by the Depositor as a result of the losses, claims,
damages or liabilities of the Depositor in such proportion as is appropriate to

                  (i)      loan number;

                  (ii)     current Mortgage Rate;

                  (iii)    current principal balance;

                  (iv)     original principal balance;

                  (v)      prepayment penalty amount due;

                  (vi)     prepayment penalty amount collected; and

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

         SECTION 3.24. Statements to Trustee. Not later than the tenth calendar
day of each month, the Servicer shall furnish to the Trustee and the NIMs
Insurer 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

information described in Section 4.05(a).

         SECTION 3.25. Indemnification.

         The Servicer shall indemnify the Seller, the Trust Fund, Trustee, the
Depositor and the NIMs Insurer and hold each of them harmless against any and
all claims, losses, damages, penalties, fines, forfeitures, reasonable and
necessary legal fees and related costs, judgements, 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. The Servicer immediately shall
notify the Seller, the Trustee, the Depositor and the NIMs Insurer or any other
relevant party if a claim is made by a third party with respect to this
Agreement or the Mortgage Loans, 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 judgement or
decree which may be entered against it or any of such parties in respect of such

Trustee and the NIMs Insurer in connection with such claim. The Servicer shall
provide the Trustee, the Depositor and the NIMs Insurer 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 preceding sentence except when the claim in any way relates to the
failure of the Servicer to service and administer the Mortgage Loans in material
compliance with the terms of this Agreement or the gross negligence, bad faith
or willful misconduct of the Servicer. The provisions of this paragraph shall
survive the termination of this Agreement and the payment of the outstanding
Certificates.

         SECTION 3.26. Nonsolicitation.

         For as long as the Servicer services the Mortgage Loans, the Servicer
covenants that it will not, and that it will ensure that its affiliates and
agents, will not, directly solicit or provide information for any other party to
solicit for prepayment or refinancing of any of the Mortgage Loans by the
related Mortgagors. It is understood that the promotions undertaken by the
Servicer which are directed to the general public at large, or certain segments
thereof, shall not constitute solicitation as that term is used in this Section
3.26.

         SECTION 3.27. 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 Section 10.01 of the Existing Servicing Agreement.

                                   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 1:00
p.m. New York City time on the Servicer Advance Date in immediately available
funds. The Servicer shall be obligated to make any such Advance only to the
extent that such advance would not be a Non-Recoverable Advance. If the Servicer
shall have determined that it has made a Non-Recoverable Advance or that a
proposed Advance or a lesser portion of such Advance would constitute a
Non-Recoverable Advance, the Servicer shall deliver (i) to the Trustee for the
benefit of the Certificateholders funds constituting the remaining portion of
such Advance, if applicable, and (ii) to the Depositor, the NIMs Insurer, each
Rating Agency and the Trustee an Officer's Certificate setting forth the basis
for such determination. The Servicer may, in its sole discretion, make an
Advance with respect to the principal portion of the final Scheduled Payment on
a Balloon Loan, but the Servicer is under no obligation to do so; provided,
however, that nothing in this sentence shall affect the Servicer's obligation
under this Section 4.01 to Advance the interest portion of the final Scheduled
Payment with respect to a Balloon Loan as if such Balloon Loan were a fully
amortizing Mortgage Loan. If a Mortgagor does not pay its final Scheduled
Payment on a Balloon Loan when due, the Servicer shall Advance (unless it
determines in its good faith judgment that such amounts would constitute a
Nonrecoverable 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 Advance 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

                                       76

REO Property has been liquidated or until the purchase or repurchase thereof (or
substitution therefor) from the Trust Fund 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, 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 Advance 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 0.30% 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 Trust Fund 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.

         SECTION 4.03. Distributions on the REMIC Interests.

         On each Distribution Date, amounts on deposit in the Certificate
Account shall be treated for federal income tax purposes as applied to
distributions on the interests in REMIC 1 and REMIC 2 in an amount sufficient to
make the distributions on the respective Certificates on such Distribution Date
in accordance with the provisions of Section 4.04.

         SECTION 4.04. Distributions.

         (a)      [RESERVED].

         (b)      On each Distribution Date, the Trustee shall make the

         prepayment penalties collected on the Mortgage Loans and (A) any
         amounts paid by the Seller or the Servicer in respect of prepayment
         charges pursuant to this Agreement or (B) any amounts received in
         respect of any indemnification paid as a result of a prepayment charge
         being unenforceable in breach of the representations and warranties set
         forth in the Sale Agreement received during the related Prepayment
         Period;

                  (ii)     to each Class of the Class R, Class A-1, Class A-2,
         Class A-3A and Class A-3B Certificates, the Current Interest and any
         Interest Carry Forward Amount with respect to each such Class;
         provided, however, if such amount is not sufficient to make a full
         distribution of the Current Interest and any Interest Carry Forward
         Amount to all of the Class R, Class A-1, Class A-2, Class A-3A and
         Class A-3B Certificates, such amount will be distributed pro rata among
         each Class of the Class R, Class A-1, Class A-2, Class A-3A and Class
         A-3B Certificates based on the ratio of (x) the Current Interest and
         Interest Carry Forward Amount for such Class to (y) the total amount of
         Current Interest and any Interest Carry Forward Amount for the Class R,
         Class A-1, Class A-2, Class A-3A and Class A-3B Certificates;

                                       77

         and any Interest Carry Forward Amount for such class;

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

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

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

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

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

                  (ix)     to the Residual Certificate, the Residual Interest
         Amount; and

                  (x)      any remainder pursuant to Section 4.04(e) hereof.

         (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, the Trustee shall make the
following distributions from the Certificate Account of an amount equal to the
Principal Distribution Amount in the following order of priority, and each such
distribution shall be made only after all distributions pursuant to Section
4.04(b) above shall have been made until such amount shall have been fully
distributed for such Distribution Date:

rights of any party to an adversary proceeding action with respect to any court
order issued in connection with any such Preference Claim; provided, however,
that the NIMs Insurer will not have any rights with respect to any Preference
Claim set forth in this paragraph unless the indenture trustee with respect to
the NIM Notes or the holder of any NIMs Notes has been required to relinquish a
distribution made on the Class C Certificates, the Class P Certificates or the
NIM Notes, as applicable, and the NIMs Insurer made a payment in respect of such
relinquished amount.

statement containing the information set forth in clauses (a)(i) and (a)(ii) of

thereof during which such Person was a Certificateholder. Such obligation of the

(1)      The Class C Certificates shall not have a minimum dollar denominations
         as the Certificate Principal Balance thereof shall vary over time as
         described herein.

(3)      The Class P Certificates shall not have minimum dollar denominations or
         Certificate Principal Balance and shall be issued in a minimum
         percentage interest of 25%.

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

                                       84
<PAGE>

subsections (b) and (c) below and to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of Certificates and of
Transfers and exchanges of Certificates as herein provided. Upon surrender for
registration of Transfer of any Certificate, the Trustee 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 a Trustee. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute and the Trustee 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 a 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 each 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 each 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 an ERISA Restricted Certificate shall be made unless the
Trustee shall have received either (i) a representation from the transferee of
such Certificate acceptable to and in form and substance satisfactory to the
Trustee and the NIMs Insurer, to the effect that such transferee is not an

                                       85
<PAGE>

employee benefit plan subject to Title I of ERISA or a plan subject to Section
4975 of the Code or a plan subject to any applicable Federal, state or local law
materially similar to the foregoing provisions of ERISA and the Code ("Similar
Law"), or a Person acting on behalf of any such plan or using the assets of any
such plan, or (ii) in the case of any such ERISA Restricted Certificate, other
than a Class R Certificate, presented for registration in the name of an
employee benefit plan subject to ERISA, a plan subject to Section 4975 of the
Code, or a plan subject to Similar Law (or comparable provisions of any
subsequent enactments), or a trustee of any such plan or any other person acting
on behalf of any such plan, an Opinion of Counsel satisfactory to the Trustee
and the NIMs Insurer to the effect that the purchase and holding of such ERISA
Restricted Certificate will not result in a prohibited transaction under ERISA
or the Code or Similar Law and will not subject the NIMs Insurer or the Trustee
to any obligation in addition to those expressly undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the NIMs Insurer or the
Trustee. For purposes of clause (i) of the preceding sentence, such
representation shall be deemed to have been made to the Trustee by the
transferee's acceptance of an ERISA Restricted Certificate (or the acceptance by
a Certificate Owner of the beneficial interest in any Class of ERISA Restricted
Certificates) unless the Trustee shall have received from the transferee an
alternative representation acceptable in form and substance to the Trustee.
Notwithstanding anything else to the contrary herein, any purported transfer of
an ERISA Restricted Certificate to or on behalf of an employee benefit plan
subject to Title I of ERISA, a plan subject to Section 4975 of the Code, or a
plan subject to Similar Law without the delivery to the Trustee and the NIMs
Insurer of an Opinion of Counsel satisfactory to the Trustee and the NIMs
Insurer as described above shall be void and of no effect. The Trustee shall be
under no liability to any Person for any registration of transfer of any ERISA
Restricted Certificate that is in fact not permitted by this Section 5.02(b) or
for making any payments due on such Certificate to the Holder thereof or taking
any other action with respect to such Holder under the provisions of this
Agreement so long as the transfer was registered by the Trustee in accordance
with the foregoing requirements. The Trustee shall be entitled, but not
obligated, to recover from any Holder of any ERISA Restricted Certificate that
was in fact an employee benefit plan subject to Title I of ERISA, a plan subject
to Section 4975 of the Code, or a plan subject to Similar Law or a Person acting
on behalf of any such plan at the time it became a Holder or, at such subsequent
time as it became such a plan or Person acting on behalf of such a plan, all
payments made on such ERISA Restricted 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 Holder of such Certificate that is not such
a plan or Person acting on behalf of a plan.

         No Transfer of a Class C Certificate may be made to a person that is
either (i) not a "United States person" (as defined for purposes of Section 7701
of the Code) or (ii) a Disqualified Organization or a Person acquiring such
Certificate on behalf (as a broker, agent, nominee or otherwise) of a
Disqualified Organization. The Trustee shall not register any Transfer of a
Class C Certificate unless the Trustee shall have been furnished with a
Transferee Letter or a letter from the initial Holder of the Class C
Certificates in the form attached as Exhibit M. Any Transfer of a Class C
Certificate in violation of the provisions of this Section 5.02(b) shall be
absolutely null and void and the purported Transferee shall acquire absolutely
no rights in such Class C Certificate.

         (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.

                                       86
<PAGE>

                  (ii)     No Ownership Interest in a Class R Certificate may be
         purchased, transferred or sold, directly or indirectly, except in
         accordance with the provisions hereof. No Ownership Interest in a Class
         R Certificate may be registered on the Closing Date or thereafter
         transferred, and the Trustee shall not register the Transfer of any
         Class R Certificate unless, in addition to the certificates required to
         be delivered to the Trustee under subparagraph (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 LT-R Interest and the Residual Interest may be
         severed and represented by separate certificates; provided, however,
         that such separate certification may not occur until the NIMs Insurer
         and the Trustee receive an Opinion of Counsel addressed to the Trustee
         to the effect that separate certification in the form and manner
         proposed would not result in the imposition of federal tax upon the
         Trust Fund 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)

                                       87
<PAGE>

         will apply to each such separate certificate as if the separate
         certificate were a Class R Certificate. If, as evidenced by an Opinion
         of Counsel, it is necessary to preserve the REMIC status of any of the
         REMICs provided for herein, the Class LT-R Interest and the Residual
         Interest shall be severed and represented by separate Certificates.

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

         SECTION 5.04. Persons Deemed Owners.

         The NIMs Insurer, the Trustee and any agent of the NIMs Insurer or the
Trustee may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions as provided
in this Agreement and for all other purposes whatsoever, and neither the NIMs
Insurer nor the Trustee, nor any agent of the NIMs Insurer or the Trustee shall
be affected by any notice to the contrary.

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

         If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the NIMs
Insurer or the Depositor shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the NIMs Insurer, the Depositor or such Certificateholders
at such recipients' expense the most recent list of the Certificateholders of
the Trust Fund 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 Trustee and the NIMs Insurer 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.

                                       89
<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 Trustee shall authenticate and 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 2001 Bryan Street, 8th Floor, Dallas, Texas 75201, Attention:
Institutional Trust Services/Transfer Department 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.

                                   ARTICLE VI
                         THE DEPOSITOR AND THE SERVICER

         SECTION 6.01. Respective Liabilities of the Depositor and the Servicer.

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

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

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

         Any Person into which the Depositor or 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 nor any of the directors, officers,
employees or agents of the Depositor or the Servicer shall be under any
liability to the Trust Fund 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 Trust Fund 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 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. None of the Depositor nor the Servicer shall
be under any obligation to appear in, prosecute or defend any legal action that
is not incidental to its respective duties hereunder and that in its opinion may
involve it in any expense or liability; provided, however, that any 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

                                       91
<PAGE>

liabilities of the Trust Fund, 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.

         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 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 Trustee and the NIMs Insurer is appointed and has assumed the Servicer's
responsibilities, duties, liabilities and obligations hereunder. Any such
resignation shall not relieve the Servicer of any of the obligations specified
in Sections 7.01, 7.02 and 7.03 as obligations that survive the resignation or
termination of the Servicer.

         The Trustee and the Depositor hereby specifically (i) consent to the
pledge and assignment by the Servicer of all the Servicer's right, title and
interest in, to and under this Agreement to the Servicing Rights Pledgee, 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 or policies and bond shall, together, comply with the
requirements from time to time of Fannie Mae or Freddie Mac for Persons
performing servicing for mortgage loans purchased by Fannie Mae or Freddie Mac.
The Servicer shall provide the Trustee and the NIMs Insurer, upon request, with
copies of such policies and fidelity bond or a certification from the insurance
provider evidencing such policies and fidelity bond. In the event that any such
policy or bond ceases to be in effect, the Servicer shall use its reasonable
best efforts to obtain a comparable replacement policy or bond from an insurer
or issuer meeting the requirements set forth above as of the date of such
replacement. Any such policy or fidelity bond shall by its terms not be
cancelable without thirty days' prior written notice to the Trustee and the NIMs
Insurer.

                                  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

                                       92
<PAGE>

         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 and the Servicer by the NIMs Insurer or the Holders
         of Certificates evidencing not less than 50% of the Voting Rights
         evidenced by the Certificates; or

                  (ii)     any failure by the Servicer to observe or perform in
         any material respect any other of the covenants or agreements on the
         part of the Servicer contained in this Agreement or any representation
         or warranty shall prove to be untrue, which failure or breach shall
         continue unremedied for a period of 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 to the Trustee by the NIMs Insurer or
         the Holders of Certificates evidencing not less than 50% of the Voting
         Rights evidenced by the Certificates; or

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

         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
(with the written consent of the NIMs Insurer, except after a NIMs Insurer
Default), 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

                                       93
<PAGE>

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 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. Servicer Trigger Event

         A "Servicer Trigger Event," shall be deemed to have occurred on any
Distribution Date where the aggregate amount of cumulative Realized Losses
incurred since the Cut-off Date through the last day of the related Accrual
Period divided by the Pool Balance as of the Cut-off Date exceeds the applicable
percentages set forth below with respect to such Distribution Date:

<TABLE>
<CAPTION>
DISTRIBUTION DATE OCCURRING IN                   PERCENTAGE
----------------------------------               ----------
<S>                                              <C>
January 2007 through December 2007                  4.25%
January 2008 through December 2008                  5.60%
January 2009 through December 2009                  7.50%
January 2010 and thereafter                         8.00%
</TABLE>

         Upon discovery by the Trustee that a Servicer Trigger Event has
occurred, the Trustee shall promptly (and in any event within 5 Business Days of
discovery) give written notice thereof to the Certificateholders. If a Servicer
Trigger Event shall occur, then the Holders of Certificates evidencing not less
than 51% of the Voting Rights evidenced by the Certificates (with the written
consent of the NIMs Insurer, except after a NIMs Insurer Default), may, 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. The Trustee is hereby authorized and empowered as successor servicer
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 as successor servicer in effecting
the termination of the Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Trustee as successor servicer
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 a Servicer Trigger Event, such notice to be provided in any event
within two Business Days of such occurrence.

                                       94
<PAGE>

         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 7.03. Trustee to Act; Appointment of Successor.

         On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 or 7.02 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 or
7.02, 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 or 7.02 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 which 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 or 7.02), 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 and the NIMs Insurer shall have consented thereto, prior written
consent of the NIMs Insurer is obtained and written notice of such proposed
appointment shall have been provided by the Trustee to each Certificateholder.
The Trustee shall not resign as servicer until a successor servicer has been
appointed and has accepted such appointment. Pending appointment of a successor
to the Servicer hereunder, the Trustee, unless the Trustee is prohibited by law
from so acting, shall, subject to Section 3.04 hereof, act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
Servicer hereunder. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Neither the Trustee nor any other successor servicer shall be deemed
to be in default hereunder by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities

                                       95

hereunder, in either case caused by the failure of the Servicer to deliver or
provide, or any delay in delivering or providing, any cash, information,
documents or records to it.

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

         SECTION 7.04. 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, the NIMs Insurer and to each Rating Agency.

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

         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
counsel, and subject to the foregoing, shall deem most effectual to protect and
enforce any of the rights of the Trustee, the NIMs Insurer and the
Certificateholders.

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

         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:

                                       96
<PAGE>

                  (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
         NIMs Insurer or 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 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

                                       97
<PAGE>

         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);

                  (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 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.

         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, of any
guarantee of a NIMs Insurer 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 Trust Fund 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:

                  (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 Trust Fund 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 Trust Fund 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 Trust Fund 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 Trust Fund must constitute an "unanticipated expense" of the
         Trust Fund within the meaning of Treasury Regulations Section 1.860G-1
         (b)(3)(ii).

                                       99
<PAGE>

         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 and are outstanding and shall cease to
apply after the date on which any NIM Notes are paid in full and all amounts
which the NIMs Insurer is entitled to be paid or reimbursed shall have been paid
or reimbursed. Any amounts not in excess of this cap may be withdrawn by the
Trustee from the Certificate Account at any time.

         SECTION 8.07. Eligibility Requirements for Trustee.

         The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust powers
having a combined capital and surplus of at least $50,000,000, subject to
supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction) and reasonably acceptable to the NIMs
Insurer. If such corporation or association publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 8.07
the combined capital and surplus of such corporation or association shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. In case at any time the Trustee shall cease to
be eligible in accordance with the provisions of this Section 8.07, the Trustee
shall resign immediately in the manner and with the effect specified in Section
8.08 hereof. The corporation or national banking association serving as Trustee
may have normal banking and trust relationships with the Depositor and the NIMs
Insurer and their respective 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
the NIMs Insurer 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 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 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.

                                      100
<PAGE>

         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 Trust Fund by any state in which
the Trustee or the Trust Fund 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 Trust Fund against such tax, then the Depositor or the NIMs
Insurer may remove the Trustee and the Depositor with the consent of the NIMs
Insurer 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.

         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 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

                                      101
<PAGE>

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
such co-trustee has been appointed with due care. If the Servicer and the NIMs
Insurer shall not have joined in such appointment within 15 days after the
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, the Trustee alone shall have the power to make
such appointment. No co-trustee or separate trustee hereunder shall be required
to meet the terms of eligibility as a successor trustee under Section 8.07 and
no notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.09.

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

                  (i)      All rights, powers, duties and obligations conferred
         or imposed upon the Trustee, 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,

                                      102
<PAGE>

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.

         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 Trust Fund shall be conducted so as to allow
each such grantor trust to qualify as, a grantor trust under the provisions of
Subpart E, Part I of Subchapter J of the Code. In furtherance of such intention,
the Trustee covenants and agrees that it shall act as agent (and the Trustee is
hereby appointed to act as agent) on behalf of each of the REMICs provided for
herein and that in such capacity it shall: (a) prepare and file, or cause to be
prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment
Conduit Income Tax Return (Form 1066 or any successor form adopted by the
Internal Revenue Service) and prepare and file or cause to be prepared and filed
with the Internal Revenue Service and applicable state or local tax authorities
income tax or information returns for each taxable year with respect to each of
the REMICs and grantor trusts provided for herein, containing such information
and at the times and in the manner as may be required by the Code or state or
local tax laws, regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty 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

                                      103
<PAGE>

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, the amount of any federal, state and local
taxes, including prohibited transaction taxes as described below, imposed on
each of the REMICs provided for herein prior to the termination of the Trust
Fund when and as the same shall be due and payable (but such obligation shall
not prevent the Trustee or any other appropriate Person from contesting any such
tax in appropriate proceedings and shall not prevent the Trustee from
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings); (j) sign or cause to be signed federal, state or local income
tax or information returns; (k) maintain records relating to each of the REMICs
provided for herein, including but not limited to the income, expenses, assets
and liabilities of each of the REMICs 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 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order to
enable the Trustee to perform its duties as set forth herein. The Depositor
hereby agrees to indemnify the Trustee for any losses, liabilities, damages,
claims or expenses of the Trustee arising from any errors or miscalculations of
the Trustee that result from any failure of the Depositor to provide, or to
cause to be provided, accurate information or data to the Trustee on a timely
basis.

         In the event that any tax is imposed on "prohibited transactions" of
any of the REMICs provided for herein as defined in Section 860F(a)(2) of the
Code, on the "net income from foreclosure property" of any of such REMICs as
defined in Section 860G(c) of the Code, on any contribution to the Trust Fund
after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax
is imposed, if not paid as otherwise provided for herein, such tax shall be paid
by (i) the Trustee, if any such other tax arises out of or results from a breach
by the Trustee of any of its obligations under this Agreement or as a result of
the location of the Trustee, (ii) any party hereto (other than the Trustee) to
the extent any such other tax arises 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 otherwise to be
distributed to the Class R Certificateholders (pro rata) pursuant to Section
4.04, and second with amounts 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-3 Certificates (pro rata), sixth, to the Class
M-2 Certificates (pro rata), seventh, to the Class M-1 Certificates (pro rata)
and eighth, 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

                                      104
<PAGE>

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.

         (a)      Each of the Depositor 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 NIMs Insurer (or the Servicer) of the 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 (or the Servicer as provided in clause (e) below) 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.

Notwithstanding anything to the contrary herein, the Auction Termination Amount
received by the Trustee or the Clean Up Call Price paid by the NIMs Insurer or
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 NIMs Insurer or the Servicer shall be paid by the NIMs
Insurer or the Servicer to the Trustee for deposit into the Certificate Account.

         (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
purchaser 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

                                      105
<PAGE>

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 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.

         Any purchase shall be accomplished by deposit into the Certificate
Account of the amount paid by the winning bidder if an Auction Termination has
occurred or the amount described in the definition of "Clean Up Call Price" 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 NIMs Insurer or 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 and the NIMs Insurer does not exercise a Clean Up Call,
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)      The Class R Certificateholder hereby assigns to the Class C
Certificateholders that portion of any amount received by the Class R
Certificate upon an Auction Termination or Clean Up Call of the Trust Fund that
is attributable to clause (C) of the definition of Auction Termination Price or
clause (c) of the definition of Clean Up Call Price and required to cover what
would otherwise be a shortfall in the amounts described in clause (C) of the
definition of Auction Termination Price or clause (c) of the definition of Clean
Up Call Price.

         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 and the NIMs Insurer 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 NIMs Insurer or 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 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.

                                      106
<PAGE>

         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 the NIMs Insurer and 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 or the NIMs
Insurer, as applicable, the Mortgage Files for the Mortgage Loans.

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

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

                                      107
<PAGE>

         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 Trust Fund or the NIMs Insurer, as applicable;

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

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

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

         (c)      The Trustee as agent for each REMIC hereby agrees to adopt and
sign 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.

                                   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 to,

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

                  (ii)     To correct, modify or supplement any provision
         therein 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 effect 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.

                                      108
<PAGE>

         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 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, to the effect that such action is necessary or
appropriate to maintain such qualification or to avoid or minimize the risk of
the imposition of such a tax.

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

         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, 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. A copy of such Opinion of Counsel shall be
provided to the NIMs Insurer.

         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, the
NIMs Insurer and each Rating Agency.

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

         Nothing in this Agreement shall require the Trustee or the Servicer to
enter into an amendment without receiving an Opinion of Counsel, satisfactory to
the Trustee or the Servicer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any Certificateholder
or (B) the conclusion set forth in the immediately preceding clause (A) is not
required to be reached pursuant to this Section 10.01.

                                      109
<PAGE>

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

         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 each Rating Agency and the NIMs Insurer with respect to each of the
following of which a Responsible Officer of the Trustee has actual knowledge:

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

         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

<PAGE>

         SECTION 10.08. Limitation on Rights of Certificateholders.

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

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

         No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as hereinbefore provided,
the Holders of Certificates evidencing not less than 25% of the Voting Rights
evidenced by the Certificates shall also have made written request to the
Trustee to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses, and liabilities to be incurred therein
or thereby, and the Trustee, for 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 NIMs Insurer, the Depositor or the Trustee during the
Servicer's normal business hours, to examine all the books of account, records,
reports and other papers of the Servicer relating to the Mortgage Loans, to make
copies and extracts therefrom, to cause such books to be audited by independent
certified public accountants selected by the NIMs Insurer, 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 NIMs
Insurer, 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 Trust Fund, that the interests in
the Trust Fund represented by the Certificates shall be

                                      112
<PAGE>

nonassessable for any reason whatsoever, and that the Certificates, upon due
authentication thereof by the Trustee pursuant to this Agreement, are and shall
be deemed fully paid.

         SECTION 10.11. Third Party Rights.

         The NIMs Insurer shall be deemed a third-party beneficiary of this
Agreement to the same extent as if it were a party hereto, and shall have the
right to enforce the provisions of this Agreement.

         SECTION 10.12. Additional Rights of the NIMs Insurer.

         (a)      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 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.

         (b)      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. Credit Risk Manager.

         (a)      For and on behalf of the Depositor, the Credit Risk Manager
will provide reports and recommendations concerning certain delinquent and
defaulted Mortgage Loans, and as to the collection of any prepayment charges
with respect to the Mortgage Loans. Upon request, the Depositor shall forward
copies of such reports to the Trustee and the NIMs Insurer. Such reports and
recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the Credit Risk Management Agreement, and the Credit Risk
Manager shall look solely to the Depositor for all information and data
(including loss and delinquency information and data) relating to the servicing
of the Mortgage Loans. Upon any termination of the Credit Risk Manager or the
appointment of a successor Credit Risk Manager, the Depositor shall give written
notice thereof to the Servicer, the Trustee, and each Rating Agency.
Notwithstanding the foregoing, the termination of the Credit Risk Manager
pursuant to this Section shall not become effective until the appointment of a
successor Credit Risk Manager.

         (b)      Neither the Credit Risk Manager, nor any of its directors,
officers, employees, or agents shall be under any liability to the Trustee, the
Certificateholders, or the Depositor for any action taken or for refraining from
the taking of any action made in good faith pursuant to this Agreement, in
reliance upon information provided by the Depositor under the Credit Risk
Management Agreement, or for errors in judgment; provided, however, that this
provision shall not protect the Credit Risk Manager or any such person against
liability that would otherwise be imposed by reason of willful malfeasance or
bad faith in

                                      113
<PAGE>

its performance of its duties. The Credit Risk Manager and any director,
officer, employee, or agent of the Credit Risk Manager 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, and may rely in good faith upon
the accuracy of information furnished by the Depositor pursuant to the Credit
Risk Management Agreement in the performance of its duties thereunder and
hereunder.

         (c)      The Credit Risk Manager may be removed as Credit Risk Manager
by Certificateholders holding not less than 66 2/3% of the Voting Rights in the
Trust, in the exercise of its or their sole discretion. The Certificateholders
shall provide written notice of the Credit Risk Manager's removal to the
Trustee. Upon receipt of such notice, the Trustee shall provide written notice
to the Credit Risk Manager of its removal, which shall be effective upon receipt
of such notice by the Credit Risk Manager.

         (d)      The Servicer agrees to provide the Depositor with all
information in relation to the Mortgage Loans that is reasonably requested by
the Depositor, which information shall include, but not be limited to, monthly
data on each Mortgage Loan in the Trust, information on delinquent and defaulted
Mortgage Loans, information on prepayment charges with respect to the Mortgage
Loans, and copies of realized loss certificates or any such itemization
regarding each Liquidated Loan for the applicable Due Period.

         (e)      The Servicer shall permit the Credit Risk Manager to conduct
an on-site review and evaluation of the Servicer's operations, as they relate to
the Mortgage Loans, no more than annually, unless circumstances warrant special
review. Circumstances warranting special review shall include, but not be
limited to, a request by the Depositor that a review be conducted. The review
and evaluation will be conducted upon at least thirty (30) days prior written
notice, except in the case of special review, to the Servicer by the Credit Risk
Manager, and shall be conducted at the Credit Risk Manager's expense.

         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.

                                      114
<PAGE>

         (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 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 Trust Fund
for any claim, loss, liability or damage resulting from any claim by the related
Advancing 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 Advancing 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)      An Advance Financing Person who receives an assignment or
pledge of rights to receive Advance Reimbursement Amounts and/or whose
obligations are limited to the funding of Advances and/or Servicing Advances
pursuant to an Advance Facility shall not be required to meet the criteria for
qualification as a Sub-Servicer.

                                      115
<PAGE>

         (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 "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 Nonrecoverable 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 Nonrecoverable 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.

         affixed as Appendix A, the Transferee is a "U.S. person" (as defined

         collection of tax,

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

(7)      the Transferee intends, and believes that it will be able, to continue

         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 I
         l(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

         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

                  and

                  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

                  corporation.

                                   by the U.S. Small Business Administration

to or subscription by the Buyer, if the Buyer is a dealer, (iii) securities
issued or guaranteed by the U.S. or any instrumentality thereof, (iv) bank

Buyer, but only if such subsidiaries are consolidated with the Buyer in its
financial statements prepared in accordance with generally accepted accounting
principles and if the investments of such subsidiaries are managed under the
Buyer's direction. However, such securities were not included if the Buyer is a
majority-owned, consolidated subsidiary of another enterprise and the Buyer is
not itself a reporting company under the Securities Exchange Act of 1934, as

         without any representation or warranty, expressed or implied, of any
         kind and without recourse to, or guaranty by, the Trustee); (iv) a

         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, Depositor and

         Termination Price.
