stating that such Mortgage or assumption, consolidation or modification, as the

To the extent any required endorsement

                                      -46-
<PAGE>

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 that is not a Co-op 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. With
respect to any Co-op Loan, none of the Depositor, the Servicer or the Trustee
shall be obligated to cause to be filed the Form UCC-3 referred to in this
Section 2.01.

         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.

         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

                                      -47-

connection with the Mortgage Loans or any other agreement or instrument relating
thereto except as specifically set forth herein.

         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 Cap Contract (a form of which
is attached hereto), 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-1 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 60 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 of transfer or
assignment, without recourse, 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 and the Transfer
Agreement. The Trustee shall be under no duty

                                      -48-
<PAGE>

or obligation to inspect, review and examine such documents, instruments,
certificates or other papers to determine that they are genuine, enforceable 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 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

                                      -49-
<PAGE>

         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)      The representations and warranties of the Transferor with
respect to the related Mortgage Loans in the Transfer Agreement, which have been
assigned to the Trustee hereunder, were made as of the date specified in the
Transfer Agreement (or underlying agreement, if the Transfer Agreement is in the
form of an assignment of a prior agreement), except to the extent such
representations and warranties were brought forward in the letter agreement
dated as of the date hereof from the Transferor to the Seller. To the extent
that any fact, condition or event with respect to a Mortgage Loan constitutes a
breach of both (i) a representation or warranty of the Transferor under the
Transfer Agreement and (ii) 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 Transferor under any applicable representation or warranty made by it. The
Trustee acknowledges that the Seller shall have no obligation or liability with
respect to any breach of a representation or warranty made by it with respect to
the Mortgage Loans if the fact, condition or event constituting such breach also
constitutes a breach of a representation or warranty made by the Transferor in
the Transfer Agreement, without regard to whether the Transferor fulfills its
contractual obligations in respect of such representation or warranty. The
Trustee further 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 NIMs Insurer, or
the Trustee of a breach of any of such representations and warranties that
adversely and materially affects the value of the related Mortgage Loan,
prepayment charges or the interests of the Certificateholders, the party
discovering such breach shall give prompt written notice to the other parties.
Within 90 days of the discovery of such breach of any representation or warranty
the Transferor or the Seller, as applicable, 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 Transferor, the Depositor or
the Seller, the Trustee shall enforce its rights under the Transfer Agreement or
the Sale Agreement for the benefit of Certificateholders and the NIMs Insurer.
If a breach of the representations and warranties set forth in the Transfer
Agreement 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 the Transfer 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
Transferor substitutes for a Mortgage Loan for which there is a breach of any

                                      -50-
<PAGE>

representations and warranties in the Transfer Agreement which adversely and
materially affects the value of such Mortgage Loan and such substitute mortgage
loan is not a Replacement Mortgage Loan, under the terms of the Sale Agreement,
the 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, by the Seller pursuant to the Sale Agreement or by the
Transferor pursuant to the Transfer Agreement, the principal portion of the
funds received by the Trustee in respect of such repurchase of a Mortgage Loan
will be considered a Principal Prepayment and shall be deposited in the
Collection Account pursuant to Section 3.05(d) and the Servicer shall notify the
Trustee of its receipt of the same. 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, the
Seller or the Transferor, 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, the Transferor 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 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

                                      -51-
<PAGE>

to the aggregate of the deficiencies described in the preceding sentence (such
amount, the "Substitution Adjustment Amount") plus an amount equal to any
unreimbursed costs, penalties and/or damages incurred by the Trust Fund in
connection with any violation relating to such Deleted Mortgage Loan of any
predatory or abusive lending law shall be deposited into the Collection Account
by the Seller 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 Trustee shall cause the relevant Mortgage Loan Schedules to be
amended in accordance with the terms of this Agreement.

         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 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, (ii) of the
Seller and the Depositor set forth in the Sale Agreement and assigned to the
Trustee by the Depositor hereunder and (iii) of the Transferor, assigned by the
Seller to the Depositor pursuant to the Sale Agreement and assigned to the
Trustee by the Depositor hereunder shall each survive delivery of the Mortgage
Files and the Assignment of Mortgage of each Mortgage Loan to the Trustee and
shall continue throughout the term of this Agreement.

         SECTION 2.04. Representations and Warranties of the Servicer.

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

                  (i)      The Servicer is a duly organized corporation and is

         Servicer in any state in which a Mortgaged Property (or Underlying
         Mortgaged Property, in the case of a Co-op Loan) is located or is
         otherwise not required under applicable law to effect such
         qualification and, in any event, is in compliance with the doing
         business laws of any such state, to the extent necessary to ensure its
         ability to enforce each Mortgage Loan, to service the Mortgage Loans in
         accordance with the terms of this Agreement and to perform any of its
         other obligations under this Agreement in accordance with the terms

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

                  (iii)    The execution and delivery of this Agreement by the

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

         Servicer; and the Servicer is not in breach or violation of any
         material indenture or other material agreement or instrument, or in
         violation of any statute, order or regulation of any court, regulatory

         over it which breach or violation may materially impair the Servicer's

                  (v)      No litigation is pending or, to the best of the

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

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

         order is required, the Servicer has obtained the same.

                  (vii)    The Servicer has fully furnished and will fully
         furnish (for the period it serviced the Mortgage Loans), in accordance
         with the Fair Credit Reporting Act and its implementing regulations,
         accurate and complete information (e.g., favorable and unfavorable) on
         its borrower credit files to Equifax, Experian and Trans Union Credit
         Information Company on a monthly basis.

                  (viii)   Notwithstanding any state or federal law to the
         contrary, the Servicer shall not impose or collect a prepayment penalty
         in any instance when the mortgage debt is accelerated as the result of
         the Mortgagor's default in making the Mortgage Loan payments.

                                      -53-
<PAGE>

         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 (i) substitute, if the conditions in Section
2.03(c) with respect to substitutions are satisfied, a Replacement Mortgage Loan
for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan
within 90 days of such discovery in the same manner as it would a Mortgage Loan
for a breach of representation or warranty contained in Section 2.03. The
Trustee shall reconvey to the Depositor the Mortgage Loan to be released
pursuant hereto in the same manner, and on the same terms and conditions, as it
would a Mortgage Loan repurchased for breach of a representation or warranty
contained in Section 2.03.

         SECTION 2.06. Authentication and Delivery of Certificates.

         The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, the Trustee has caused
to be authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, Certificates duly authenticated by the 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 the duties set forth in this Agreement to the best of its ability, to
the end that the interests of the Holders of the Certificates may be adequately
and effectively protected.

         SECTION 2.07. REMIC Elections.

         (a)      The Depositor hereby instructs and authorizes the Trustee to
make an appropriate election to treat each of the Upper Tier REMIC, the Middle
Tier REMIC and the Lower Tier REMIC as a REMIC. The Trustee shall sign the
returns providing for such elections and such other tax or information returns
which are required to be signed by the Trustee under applicable law. This
Agreement shall be construed so as to carry out the intention of the parties
that each of the Upper Tier REMIC, the Middle Tier REMIC and the Lower 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 Transferors in respect of prepayment charges 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 Transfer Agreement, (iv) the
interests issued by the Lower Tier REMIC and the Middle Tier REMIC, (v) the
grantor trusts described in Section 2.07 hereof and (vi) the Cap Contract and
Cap Contract Account). The Lower Tier REMIC shall issue the Class LTA-1
Interest, Class LTA-2 Interest, Class LTA-3 Interest, Class LTB-1 Interest,
Class LTB-2 Interest, Class LTB-3 Interest, Class LTM-1 Interest, Class LTM-2
Interest, Class LTM-3 Interest and Class LTX Interest which shall be designated
as regular interests of such REMIC and shall issue the Class LTR Interest that
shall be designated as the sole class of residual interest in the Lower Tier
REMIC. Each of the Lower Tier REMIC Regular Interests shall have the
characteristics set forth in its definition.

                                      -54-
<PAGE>

         The assets of the Middle Tier REMIC shall be the Lower Tier REMIC
Regular Interests. The Middle Tier REMIC Regular Interests shall be designated
as the regular interests in the Middle Tier REMIC and the Class MTR Interest
shall be designated as the sole class of residual interests in the Middle Tier
REMIC. Each of the Middle Tier REMIC Regular Interests shall have the
characteristics set forth in its definition.

         The assets of the Upper Tier REMIC shall be the Middle Tier REMIC
Regular Interests. The REMIC Regular Interests shall be designated as the
regular interests in the Upper Tier REMIC and the Residual Interest shall be
designated as the sole class of residual interest in the Upper Tier REMIC. For
federal income tax purposes, the Pass-Through Rate on each REMIC Regular
Interest (other than the UTS REMIC Components and the Uncertificated Class C
Interest) and on the sole class of residual interest in the Upper Tier REMIC
shall be subject to a cap equal to the Net Rate.

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

         (c)      The "tax matters person" with respect to each REMIC for
purposes of the REMIC Provisions shall be the beneficial owner of the Class R
Certificate; provided, however, that the Holder of 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 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 A-3 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 Excess Interest shall be treated as a right in interest
rate cap contracts written by the Class C Certificateholders in favor of the
holders of the Class A-1 Certificates, Class A-2 Certificates, Class A-3
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,
Class A-3 Certificates, M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class B-1 Certificates, Class B-2 Certificates, 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 A-3 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 receive payments
of Excess Interest, such amounts, to the extent not derived from payments
received on the Cap Contract, will be treated as distributed by the Upper-Tier
REMIC to the Class C Certificates pro rata in payment of the amounts specified
in Section 4.04(g) and then paid to the relevant Class of Certificates pursuant
to the related interest cap agreement.

         (e)      The parties intend that the portion of the Trust Fund
consisting of the Uncertificated Class C Interest, the Cap Contract, the Cap
Contract Account and the obligation of the holders of the Class C Certificates
to pay amounts of Excess Interest to the holders of the Class A-1 Certificates,
Class A-2 Certificates, Class A-3 Certificates, Class R Certificate, Class M-1
Certificates, Class M-2

                                      -55-
<PAGE>

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 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 A-3 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 Transferor in respect of
prepayment charges pursuant to this Agreement and 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 Transfer
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.

         All payments of principal and interest at the Net Mortgage Rate on each
of the Mortgage Loans (other than prepayment penalties, amounts paid by the
Servicer 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 Transfer Agreement) received
from the Mortgage Loans shall be paid to the Lower Tier REMIC Regular Interests
until the principal balance of all such interests have been reduced to zero and
any losses allocated to such interests have been reimbursed. Any excess amounts
shall be distributed to the Class LTR Interest. On each Distribution Date, an
amount equal to 50% 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 50% of any increase in the Overcollateralization Amount that
results in a reduction in the principal balance of its Corresponding Middle Tier
REMIC Interests) and will be accrued and added to the principal balance of the
Class LTX Interest. All payments of scheduled principal and prepayments of
principal on the Mortgage Loans shall be allocated 50% to the Class LTX 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
50% of the principal amounts distributed to the Corresponding Middle Tier
Interests in reduction of their principal amounts). Notwithstanding the
preceding sentence, an amount equal to the

                                      -56-
<PAGE>

principal payments that result in a reduction in the Overcollateralization
Amount shall be treated as payable entirely to the Class LTX Interest. Realized
Losses that are allocated to the Certificates shall be applied to the Lower Tier
REMIC Marker Classes and the Class LTX Interest so 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 50% of the principal balance of
the Corresponding Middle Tier Interests and (ii) the principal balance of the
Class LTX Interest is equal to the sum of (x) 50% of the aggregate Stated
Principal Balance of the Mortgage Loans and (y) 50% of the Overcollateralization
Amount. Each Lower Tier REMIC Marker Class shall be entitled to receive an
amount equal to 50% of all amounts distributed to the Corresponding Middle Tier
Interest in respect of unreimbursed amounts of Realized Losses. The Class LTX
Interest shall be entitled to receive all other amounts distributed to the
Certificates in respect of unreimbursed amounts of Realized Losses.

         All payments of scheduled principal and prepayments on the Mortgage
Loans, and Realized Losses on the Mortgage Loans that are allocated to the
Certificates, shall be allocated among the Middle Tier REMIC Regular Interests
in the same manner as such payments or Realized Losses are allocated to the
Related Certificates (treating the Class S Certificates as Related Certificates
with respect to each of the Class MTA-1, Class MTA-2, Class MTA-3, Class MTM-1,
Class MTM-2, Class MTM-3, Class MTB-1, Class MTB-2 and Class MTB-3 Interests in
proportion to their respective principal balances and treating the Class C
Certificate as a Related Certificate with respect to the Class MTC Interest).
Each Middle Tier REMIC Regular Interest shall be entitled to receive all amounts
distributed to the Certificates in respect of unreimbursed amounts of Realized
Losses (treating the Class S Certificates as Related Certificates with respect
to each of the Class MTA-1, Class MTA-2, Class MTA-3, Class MTM-1, Class MTM-2,
Class MTM-3, Class MTB-1, Class MTB-2 and Class MTB-3 Interests in proportion to
their respective principal balances and treating the Class C Certificate as a
Related Certificate with respect to the Class MTC 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 directly 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 such Class R Certificate, as applicable, nor for any
such Losses resulting from misinformation provided by the Holder of such 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 such Class R
Certificate now or hereafter existing at law or in equity. Notwithstanding the
foregoing, however, in no event shall the Servicer have any liability (1) for
any action or omission that is taken in accordance with and in compliance with
the express terms of, or which is expressly permitted by the terms of, this
Agreement, (2) for any Losses other than those arising directly 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 the Servicer in good faith believes that there exists a substantial
question of law about whether a particular act or omission might cause any REMIC
provided for herein to fail to qualify as a REMIC, lose its status as a REMIC or
incur federal, state or local taxes as a result of a prohibited transaction or
prohibited contribution under the REMIC Provisions within the meaning of this
paragraph (whether such question arises by reason of a change in the relevant
statutes, regulations judicial decisions, administrative rulings and other
authorities or otherwise), the Servicer shall be entitled to retain counsel to
advise it on such question and the reasonable fees and expenses of such counsel
incurred by the Servicer in connection therewith shall be deemed a
Non-Recoverable Servicing Advance for all purposes of this Agreement.

         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 (but only to the extent that
such rules and requirements of the insurer do not impose any additional cost or
expense, other than incidental and non-material costs or expenses, on the
Servicer);

         (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, the Cap Contract, 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. Qualifying 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 thereof.

                          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 (or the stock allocated to a dwelling unit related to a Co-op Loan) 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 (or
the stock allocated to a dwelling unit related to a Co-op Loan) 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. Subject to
the other provisions of this Agreement, 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 and 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, including without limitation, any powers of
attorney. Upon receipt of such documents, the Depositor and/or the Trustee shall
execute such documents and deliver them to the Servicer.

         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. 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.

                                      -59-
<PAGE>

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

         The Servicer shall deliver to the PMI Insurer all reports required by
the PMI Insurer that are reasonably available to the Servicer.

         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) if and only if the
subservicer is not an affiliate of the Servicer and under the subservicing
agreement is to perform all or substantially all of the Servicer's obligations
hereunder, 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 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

                                      -60-
<PAGE>

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 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
or its designee, in its capacity as the successor servicer, shall immediately
assume the Servicer's obligation to make Advances and Servicing Advances. No
such termination or resignation shall affect any obligation of the Servicer to
pay amounts owed under this Agreement and to perform its duties under this
Agreement until its successor assumes all of its rights and obligations
hereunder. If the Servicer shall for any reason no longer be 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 succeed to the rights and obligations
of the Servicer thereunder; and the Servicer shall not thereby be relieved of
any liability or obligations under the subservicing agreement arising prior to
the date of such succession. To the extent any Servicing Transfer Costs are not
paid by the Servicer pursuant to this Agreement, 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 Loans then being serviced and
otherwise use its best efforts to effect the orderly and efficient transfer of
the subservicing agreement to the assuming party.

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

         (a)      The Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing, the Servicer may in
its discretion waive any late payment charge or, if applicable, any penalty
interest; provided, further, that the NIMs Insurer's prior written consent shall
be required for any modification, waiver or amendment since the Cut-off Date if
the aggregate number of outstanding Mortgage Loans which have been modified,
waived or amended exceeds 5% of the number of Mortgage Loans as of the Cut-Off
Date. 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

                                      -61-
<PAGE>

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) in the Servicer's
reasonable judgment as described in Section 3.01 hereof, (x) such waiver relates
to a default or a reasonably foreseeable default, (y) such waiver would maximize
recovery of total proceeds taking into account the value of such Prepayment
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), or (iv) this Agreement expressly provides
that the Servicer shall not impose or collect a prepayment penalty. 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 Certificateholders, the Collection Account. The Servicer shall deposit
into the Collection Account daily, within two Business Days (or, in the case of
the Optional Termination Amount, one Business Day) 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
         Underlying Mortgaged Property, in the case of a Co-op Loan) or released
         to either the Mortgagor or the holder of a senior lien on the Mortgaged
         Property (or Underlying Mortgaged Property, in the case of a Co-op
         Loan) in accordance with the Servicer's normal servicing procedures;

                  (iv)     all Compensating Interest;

                                      -62-
<PAGE>

                  (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)    all Purchase Prices and Substitution Adjustment
         Amounts;

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

                  (ix)     all prepayment penalties;

                  (x)      all net monthly rental income from REO Properties
         required to be deposited by the Servicer pursuant to Section 3.12; and

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

         The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, 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 or stock allocated to a dwelling unit in the case of
a Co-op Loan) and other similar ancillary fees and charges (other than
prepayment penalties) if collected, need not be remitted by the Servicer.
Rather, such fees and charges and similar amounts may be retained by the
Servicer as additional servicing compensation. In the event that the Servicer
shall remit any amount not required to be remitted and not otherwise subject to
withdrawal pursuant to Section 3.08 hereof, it may at any time withdraw or
direct the Trustee, or such other institution maintaining the Collection
Account, to withdraw such amount from the Collection Account, any provision
herein to the contrary notwithstanding. The Servicer shall maintain adequate
records with respect to all withdrawals made pursuant to this Section. All funds
deposited in the Collection Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08. In no event
shall the Trustee incur liability for withdrawals from the Collection Account at
the direction of the Servicer.

         The Servicer shall give notice to the 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

                                      -63-
<PAGE>

                  (iii)    the Optional Termination Amount paid by the Trustee
         or the NIMs Insurer 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 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 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 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 or withdrawn by it no less often than
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 other than those losses that the Servicer
has previously covered pursuant to this Section) 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

                                      -64-
<PAGE>

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 to itself, or, if required by law or the terms of the related Mortgage
or Mortgage Note, certain Mortgagors, on balances in the Escrow Account, to
withdraw funds deposited in error, or to clear and terminate the Escrow Account
at the termination of this Agreement in accordance with Section 9.01 hereof. The
Escrow Accounts shall not be a part of the Trust Fund.

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

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

         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 or recovery
         of interest on a Mortgage Loan that equals the Servicing Fee for the
         period with respect to which such interest payment or recovery was made
         or allocated, 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 (A) any amounts
         received on particular Mortgage Loan(s) (including, for this purpose,
         Liquidation Proceeds and purchase and repurchase proceeds) that
         represent (I) late payments or recoveries of principal and/or interest
         on such particular Mortgage Loan(s) in respect of which any such
         Advance was made or (II) amounts allocated to principal and/or interest
         out of the net monthly rental income from REO Property in respect of
         which any such Advance was made and (B) any amounts allocated to
         principal and/or interest or to unreimbursed Advances out of the
         Optional Termination Amount;

                  (iii)    to reimburse the Servicer for any Non-Recoverable
         Advance previously made by it and, any Non-Recoverable Servicing
         Advance previously made by it;

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

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

                  (vi)     to pay 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) being limited to (A) any amounts received on particular Mortgage
         Loan(s)(including, for this purpose, Liquidation Proceeds and purchase
         and repurchase proceeds)

                                      -65-
<PAGE>

         that represent (I) late recoveries of the payments for which such
         advances were made pursuant to Section 3.01 or Section 3.06 or (II)
         amounts allocated to unreimbursed Servicing Advances out of the net
         monthly rental income from REO Property in respect of which such
         Servicing Advances were made and (B) amounts allocated to unreimbursed
         Servicing Advances out of the Optional Termination Amount;

                  (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 either of them in connection with the Mortgage
         Loans or the Certificates and reimbursable pursuant to Section 3.25 or
         6.03 hereof;

                  (ix)     [reserved];

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

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

                  (xii)    to transfer funds to another Eligible Account in
         accordance with Section 3.05;

                  (xiii)   to withdraw any funds deposited in error; and

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

         In addition, no later than 12:00 noon Eastern Time on the Servicer
Remittance Date, the Servicer shall cause to be withdrawn from the Collection
Account Interest Funds and the Principal Funds, to the extent on deposit, and
such amount shall be deposited in the Certificate Account.

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

         The Servicer shall provide written notification to the Trustee 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.

                                      -66-
<PAGE>

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

         (b)      The Trustee shall withdraw funds from the Certificate Account
for distribution to the Certificateholders in the manner specified in this
Agreement (and 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 shall from time to time make withdrawals from the Certificate
Account for the following purposes:

                  (i)      to reimburse the Trustee for expenses incurred by the
         Trustee and reimbursable pursuant to Section 8.06 hereof;

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

                  (iii)    to pay to the Credit Risk Manager, the Credit Risk
         Manager Fee;

                  (iv)     to pay to the PMI Insurer, the applicable PMI Insurer
         Fee;

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

                  (vi)     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.)

         SECTION 3.09. [RESERVED].

         SECTION 3.10. Maintenance of Hazard Insurance.

         The Servicer shall cause to be maintained, for each Mortgage Loan
(other than a Co-op Loan), fire and 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 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

                                      -67-
<PAGE>

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, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
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 (or stock allocated to a dwelling unit, in the case of a
Co-op Loan) 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 (or stock allocated to a dwelling unit, in the case of Co-op
Loan) 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

                                      -68-
<PAGE>

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 (or the
stock allocated to a dwelling unit, in the case of a Co-op Loan) 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
(or stock allocated to a dwelling unit, in the case of a Co-op Loan) 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
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 (or stock allocated to a dwelling unit, in the case
of a Co-op Loan), as contemplated in Section 3.08 hereof. If the Servicer has
knowledge that a Mortgaged Property (or Underlying Mortgaged Property, in the
case of a Co-op Loan) 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 (or stock
allocated to a dwelling unit, in the case of a Co-op Loan), 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 shall prepare a statement with respect to each

                                      -69-
<PAGE>

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 the Determination Date
immediately following the month concerned. 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 (or
stock allocated to a dwelling unit, in the case of a Co-op Loan) as aforesaid or
otherwise in connection with a default or imminent default on a Mortgage Loan,
the Servicer shall dispose of such Mortgaged Property (or stock allocated to a
dwelling unit, in the case of a Co-op Loan) 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 (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 (or stock allocated to a dwelling unit, in the case of a
Co-op Loan) 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 (or stock allocated to a dwelling unit, in the case
of Co-op Loan) (subject to any conditions contained in such Opinion of Counsel).
Notwithstanding any other provision of this Agreement, no Mortgaged Property (or
stock allocated to a dwelling unit, in the case of Co-op Loan) 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 pursuant to any terms that would (i) cause such Mortgaged Property(or
stock allocated to a dwelling unit, in the case of Co-op Loan) 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 (or stock allocated to a dwelling unit, in the case of
Co-op Loan) 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 any unpaid or unreimbursed Servicing
Fees, Advances, Servicing Advances and any management fee paid or to be paid
with respect to the management of such Mortgaged Property (or stock allocated to
a dwelling unit, in the case of Co-op Loan), 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
net 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 that any such net 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.

                                      -70-
<PAGE>

         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 within two Business Days after receipt thereof for
distribution pursuant to the provisions hereof on the Distribution Date
immediately following the Prepayment Period in which such Liquidation Proceeds
are received.

         The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds and any net 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
unpaid Servicing Fees, pursuant to Section 3.08(a)(vi) or this Section 3.12;
second, to reimburse the Servicer for any unreimbursed Advances, pursuant to
Section 3.08(a)(ii) or this Section 3.12; third, to accrued and unpaid interest
(to the extent no Advance has been made for such amount) on the Mortgage Loan or
related REO Property, at the applicable Net Mortgage Rate to the Due Date
occurring in the month in which such amounts are required to be distributed;
fourth, to any prepayment penalties (to the extent that such items are permitted
to be collected hereunder); and fifth, 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.

         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 (or
stock allocated to a dwelling unit, in the case of Co-op Loan) 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

                                      -71-
<PAGE>

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 respectively caused by it.

         If the Servicer at any time seeks to initiate a foreclosure proceeding
in respect of any Mortgaged Property (or stock allocated to a dwelling unit, in
the case of Co-op Loan) 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 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 (or stock
allocated to a dwelling unit, in the case of Co-op Loan) and the Servicer shall
have delivered to the Trustee or its designee an Officer's Certificate of a
Servicing Officer certifying as to the name and address of the Person to which
the Mortgage File or the documents therein were delivered and the purpose or
purposes of such delivery.

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

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

         SECTION 3.15. Servicing Compensation.

         As compensation for its activities hereunder, the Servicer shall be
entitled to retain or withdraw from the Collection Account out of each payment
or recovery of interest on a Mortgage Loan included in the Trust Fund an amount
equal to the applicable Servicing Fee.

         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

                                      -72-
<PAGE>

Mortgaged Property (or stock allocated to a dwelling unit, in the case of Co-op
Loan)) and similar fees or charges payable by the Mortgagor (including any fees,
charges, and similar amounts described in Section 3.05(d) hereof and further
including any fees described in Section 3.11(b) hereof, 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
maintenance of blanket insurance coverage pursuant to 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 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 March 1 of each year,
beginning in 2004 or such other date in order to remain in compliance with the
Section 302 Requirements, an Officer's Certificate stating, as to each signatory
thereof, that (i) a review of the activities of the Servicer during the
preceding 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 to each Rating Agency. Copies of such
statement shall be provided by the Trustee to any Certificateholder upon written
request at the Certificateholder's expense, provided such statement has been
delivered by the Servicer to the Trustee.

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

         On or before March 1 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 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. The Trustee shall deliver to the NIMs
Insurer upon written request: (i) a copy of such USAP Report, and (ii) the
Servicer's annual officer's certificate as to compliance with this Agreement
provided by the Servicer to the Trustee pursuant to Section 3.17. 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)      As part of the Form 10-K required to be filed pursuant to the
terms of this Agreement, the Trustee shall include such accountants report as
well as the Officer's Certificate delivered by the Servicer pursuant to Section
3.17 relating to the Servicer's performance of its obligations under this
Agreement and any significant deficiencies relating to the Servicer's compliance
set forth in the report of the Servicer's certified independent accountants
described above.

         (b)      The Depositor shall prepare and file the initial report on
Form 8-K. The Trustee shall prepare for filing, and execute (other than the Form
10-Ks and the Certification), on behalf of the Trust Fund, and file with the
Securities and Exchange Commission, (i) within 15 days after each Distribution
Date in each month, each Monthly Statement on Form 8-K under the Exchange Act
executed by the Trustee, (ii) on or before March 31 of each year beginning in
2004 or such other date in order to remain in compliance with the Section 302
Requirements, a Form 10-K under the Exchange Act executed by the Depositor,
including any certification (the "Certification") required by the Section 302
Requirements, and (iii) any and all reports, statements and information
respecting the Trust Fund and/or the Certificates required to be filed on behalf
of the Trust Fund under the Exchange Act executed by the Trustee. The
Certification shall be executed by a senior officer of the Depositor. Upon such
filing with the Securities and Exchange Commission, the Trustee shall promptly
deliver to the Depositor a copy of any such executed report, statement or
information. Prior to making any such filings and certifications, the Trustee
shall comply with the provisions set forth in this Section. If permitted by
applicable law and unless the Depositor otherwise directs, the Trustee shall
file a Form 15 under the Exchange Act as soon as it is able to do so. The
Depositor hereby grants to the Trustee a limited power of attorney to execute
(other than the Form 10-Ks and the Certification) and file each such document on
behalf of the Depositor. Such power of attorney shall continue until either the
earlier of (i) receipt by the Trustee from the Depositor of written termination
of such power of attorney and (ii) the termination of the Trust 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
this Section shall only apply with respect to periods for which the Trustee is
obligated to file Form 8-Ks and 10-Ks pursuant to paragraph (b) of this Section.
In the event a Form 15 is properly filed pursuant to paragraph (b) of this
Section, there shall be no further obligations under paragraphs (a) through (c)
of this Section commencing with the fiscal year in which the Form 15 is filed
(other than the obligations in paragraphs (a) and (b) of this Section to be
performed in such fiscal year that relate back to the prior fiscal year).

         SECTION 3.21. Annual Certificate by Trustee

         (a)      Within 15 days prior to the date on which a Form 10-K is to be
filed with a Certification by the Depositor, an officer of the Trustee shall
execute and deliver an Officer's Certificate, signed by the senior officer in
charge of the Trustee or any officer to whom that officer reports, to the
Depositor for the benefit of such Depositor and its officers, directors and
affiliates, certifying as to the matters described in the Officer's Certificate
attached hereto as Exhibit K.

                                      -74-
<PAGE>

         (b)      The Trustee shall indemnify and hold harmless the Depositor
and its officers, directors, agents and affiliates from and against any losses,
damages, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments and other costs and expenses arising out of or based upon a breach by
the Trustee or any of its officers, directors, agents or affiliates of its
obligations under this Section 3.21 any material misstatement or omission in the
Officer's Certificate required under this Section or the negligence, bad faith
or willful misconduct of the Trustee in connection therewith. If the
indemnification provided for herein is unavailable or insufficient to hold
harmless the Depositor, then the Trustee agrees that it shall contribute to the
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
reflect the relative fault of the Trustee on the one had and the Depositor on
the other in connection with a breach of the Trustee's obligations under this
Section 3.21, any material misstatement or omission in the Officer's Certificate
required under this Section or the Trustee's negligence, bad faith or willful
misconduct in connection therewith.

         SECTION 3.22. Annual Certificate by Servicer

         (a)      Within 15 days prior to the date on which a Form 10-K is
required to be filed with a Certification by the Depositor, the Servicer shall
execute and deliver an Officer's Certificate in the form of Exhibit L attached
hereto, signed by the senior officer in charge of servicing of the Servicer or
any officer to whom that officer reports, to the Trustee and Depositor for the
benefit of the Trustee and Depositor and their respective officers, directors
and affiliates, certifying as to the following matters:

                  (i)      I have reviewed the information required to be
         delivered to the Trustee pursuant to the Servicing Agreement (the
         "Servicing Information").

                  (ii)     Based on my knowledge, the information in the Annual
         Statement of Compliance, and all servicing reports, officer's
         certificates and other information relating to the servicing of the
         Mortgage Loans submitted to the Trustee by the Servicer taken as a
         whole, does not contain any untrue statement of a material fact or omit
         to state a material fact necessary to make the statements made, in
         light of the circumstances under which such statements were made, not
         misleading as of the last day of the period covered by the Annual
         Statement of Compliance;

                  (iii)    Based on my knowledge, the Servicing Information
         required to be provided to the Trustee by the Servicer under this
         Agreement has been provided to the Trustee; and

                  (iv)     I am responsible for reviewing the activities
         performed by the Servicer under this Agreement and based upon the
         review required hereunder, and except as disclosed in the Annual
         Statement of Compliance, the Annual Independent Certified Public
         Accountant's Servicing Report and all servicing reports, officer's
         certificates and other information relating to the servicing of the
         Mortgage Loans submitted to the Trustee by the Servicer, the Servicer
         has, as of the last day of the period covered by the Annual Statement
         of Compliance fulfilled its obligations under this Agreement.

         (b)      The Servicer shall indemnify and hold harmless the Depositor
and their respective officers, directors, agents and affiliates from and against
any losses, damages, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments and other costs and expenses arising out of or based
upon a breach by the Servicer or any of its officers, directors, agents or
affiliates of its obligations under this Section 3.22, any material misstatement
or omission in the Officer's Certificate required under this Section or the
negligence, bad faith or willful misconduct of the Servicer in connection
therewith. If the indemnification provided for herein is unavailable or
insufficient to hold harmless the Depositor, then the Servicer agrees that it
shall contribute to the amount paid or payable by the Trustee and the Depositor
as a result of the losses, claims, damages or liabilities of the Depositor in
such proportion as is appropriate to

                                      -75-

reflect the relative fault of the Depositor on the one hand and the Servicer on
the other in connection with a breach of the Servicer's obligations under this
Section 3.22, any material misstatement or omission in the Officer's Certificate
required under this Section or the Servicer's negligence, bad faith or willful
misconduct in connection therewith.

         SECTION 3.23. Prepayment Penalty Reporting Requirements

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

                  (i)      loan number;

                  (ii)     current Mortgage Rate;

                  (iii)    current principal balance;

                  (iv)     original principal balance;

                  (v)      prepayment penalty amount due;

                  (vi)     prepayment penalty amount collected;

                  (vii)    amount of prepayment penalty paid; and

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

         SECTION 3.24. Statements to Trustee

         (a)      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 agreed upon between the
Servicer and the Trustee, including but not limited to information sufficient to
allow the Trustee to prepare the Monthly Statement described in Section 4.05(a).

         SECTION 3.25. Indemnification

         (a)      The Servicer shall indemnify the Seller, the Trust Fund, the
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 material 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 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

                                      -76-
<PAGE>

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

         (a)      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.

                                  ARTICLE III
                                  DISTRIBUTIONS

         SECTION 4.01. Advances.

         (a)      Subject to the conditions of this Article IV, the Servicer, as
required below, shall make an Advance and deposit such Advance in the Collection
Account. Each such Advance shall be remitted to the Collection Account no later
than 1:00 p.m. Eastern 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
Non-Recoverable Advance) a full month of interest (net of the Servicing Fee) on
the Stated Principal Balance thereof each month until its Stated Principal
Balance is reduced to zero.

         In lieu of making all or a portion of such Advance from its own funds,
the Servicer may (i) cause to be made an appropriate entry in its records
relating to the Collection Account that any Amount Held for Future Distribution
has been used by the Servicer in discharge of its obligation to make any such
Advance and (ii) transfer such funds from the Collection Account to the
Certificate Account. Any funds so applied and transferred 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 stock allocated to a
dwelling unit, in the case of Co-op Loan) or related 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.

         (b)      Notwithstanding anything in this Agreement to the contrary
(including, but not limited to, Sections 3.01 and 4.01(a) hereof), no Advance or
Servicing Advance shall be required to be made

                                      -77-
<PAGE>

hereunder by the Servicer if such Advance or Servicing Advance would, if made,
constitute a Non-recoverable Advance or a Non-recoverable Servicing Advance. The
determination by the Servicer that it has made a Non-recoverable Advance or a
Non-recoverable Servicing Advance or that any proposed Advance or Servicing
Advance, if made, would constitute a Non-recoverable Advance or a
Non-recoverable Servicing Advance, respectively, shall be evidenced by an
Officer's Certificate of the Servicer delivered to the Depositor, the NIMs
Insurer, each Rating Agency and the Trustee. In addition, the Servicer shall not
be required to advance any Relief Act Shortfalls.

         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 related
Servicing Fee for such Distribution Date, deposit into the Collection Account,
as a reduction of the related Servicing Fee (but not below zero) for such
Distribution Date, no later than the Servicer Advance Date immediately preceding
such Distribution Date, an amount up to the Prepayment Interest Shortfall; and
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 Mortgage Loan and 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
Offered Certificates, pro rata based upon the amount of interest each such Class
would otherwise be entitled to receive on such Distribution Date.
Notwithstanding the foregoing, the Servicer shall not be obligated to pay
Compensating Interest with respect to any Relief Act Shortfall.

         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 both the Lower Tier REMIC and the Middle Tier
REMIC in an amount sufficient to make the distributions on the respective
Certificates on such Distribution Date in accordance with the provisions of
Section 4.04.

         SECTION 4.04. Distributions.

         (a)      On each Distribution Date, the Trustee shall pay to the Credit
Risk Manager, the Credit Risk Manager Fee and to the PMI Insurer, the PMI
Insurer Fee for such Distribution Date from Interest Funds then on deposit in
the Certificate Account.

         (b)      On each Distribution Date, the Trustee shall make the
following distributions from the Certificate Account of an amount equal to the
Interest Funds remaining after the distributions in (a) above, in the following
order of priority:

                  (i)      to the Class P Certificates, an amount equal to any
         prepayment penalties collected on the Mortgage Loans and any amounts
         paid by the Transferor (A) in respect of prepayment charges pursuant to
         this Agreement (or amounts deposited by the Servicer pursuant to
         Section 3.05(b))or (B) any amounts received in respect of any
         indemnification paid by the Servicer as a result of a prepayment charge
         being unenforceable in breach of the representations and warranties set
         forth in the Transfer Agreement received during the related Prepayment
         Period;

                  (ii)     to each Class of the Class R Certificate, Class A-1
         Certificates, Class A-2 Certificates, Class A-3 Certificates and Class
         S Certificates, the Current Interest and any Interest Carry Forward
         Amount with respect to each such Class; provided, however, if such
         amount is not

                                      -78-
<PAGE>

         sufficient to make a full distribution of the Current Interest and any
         Interest Carry Forward Amount with respect to the Class R Certificate,
         Class A-1 Certificates, Class A-2 Certificates, Class A-3 Certificates
         and Class S Certificates, such amount will be distributed pro rata
         among the Class R Certificate, Class A-1 Certificates, Class A-2
         Certificates, Class A-3 Certificates and Class S Certificates based on
         the ratio of (x) the Current Interest and Interest Carry Forward Amount
         for each of the Class R Certificate, Class A-1 Certificates, Class A-2
         Certificates, Class A-3 Certificates and Class S Certificates to (y)
         the total amount of Current Interest and any Interest Carry Forward
         Amount for the Class R Certificate, Class A-1 Certificates, Class A-2
         Certificates, Class A-3 Certificates and Class S Certificates;

                  (iii)    to the Class M-1 Certificates, the Class M-1 Current
         Interest and any Class M-1 Interest Carry Forward Amount;

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

                  (v)      to the Class M-3 Certificates, the Class M-3 Current
         Interest and any Class M-2 Interest Carry Forward Amount;

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

         Interest and any Class B-2 Interest Carry Forward Amount;

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

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

         (c)      [RESERVED].

         (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:

                  (i)      to the Class A Certificates, the Class A Principal
         Distribution Amount will be distributed as follows: the Group One
         Principal Distribution Amount will be distributed sequentially to the
         Class R Certificate until its Certificate Principal Balance is reduced
         to zero and then to the Class A-1 Certificates until its Certificate
         Principal Balance has been reduced to zero; the Group Two Principal
         Distribution Amount will be distributed to the Class A-2 Certificates

         (e)      [Reserved].

         (f)      On each Distribution Date, the Trustee shall make the
following distributions up to the following amounts from the Certificate Account
of the remainders pursuant to Section 4.04(b)(ix) and (d)(viii) hereof and, to
the extent required to make the distributions set forth below in clauses (i)
through (vii) of this Section 4.04(f), and each such distribution shall be made
only after all distributions pursuant to Sections 4.04(b) and (d) above shall
have been made until such remainders shall have been fully distributed for such

         reduced to zero; provided, however, that amounts (not to exceed $0.29)
         that, but for this Section 4.04(f)(viii), would be distributed pursuant
         to Section 4.04(h) shall not be available for distributions pursuant to

         Realized Loss Amount; and

                  (ii)     the remainder pursuant to Section 4.04(h) hereof.

         (h)      On each Distribution Date, the Trustee shall allocate the

reimburse amounts or pay indemnification amounts owing to the Trustee from the
Trust Fund pursuant to Section 8.05 to the extent such amounts shall have
exceeded the cap set forth in Section 8.06(c), and (ii) thereafter, to the Class
R Certificate and such distributions shall be made only after all preceding
distributions shall have been made until such remainder shall have been fully
distributed.

         (i)      On each Distribution Date, after giving effect to
distributions on such Distribution Date, the Trustee shall allocate the Applied
Realized Loss Amount for the Certificates to reduce the Certificate Principal
Balances of the Class C and Subordinated Certificates in the following order of

         Certificate Principal Balance is reduced to zero.

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

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

                                      -81-
<PAGE>

         The Trustee shall promptly notify the NIMs Insurer of any proceeding or
the institution of any action, of which a Responsible Officer of the Trustee has
actual knowledge, seeking the avoidance as a preferential transfer under
applicable bankruptcy, insolvency, receivership or similar law (a "Preference
Claim") of any distribution made with respect to the Class C Certificates or the
Class P Certificates. Each Holder of the Class C Certificates or the Class P
Certificates, by its purchase of such Certificates and the Trustee hereby agree
that the NIMs Insurer may at any time during the continuation of any proceeding
relating to a Preference Claim direct all matters relating to such Preference
Claim, including, without limitation, (i) the direction of any appeal of any
order relating to such Preference Claim and (ii) the posting of any surety,
supersedes or performance bond pending any such appeal. In addition and without
limitation of the foregoing, the NIMs Insurer shall be subrogated to the rights
of the Trustee and each Holder of the Class C Certificates and the Class P
Certificates in the conduct of any such Preference Claim, including, without
limitation, all 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.

         (k)      Any payments received under the terms of the Cap Contract will
be available to pay the holders of the Offered Certificates (other than the
Class S Certificates) in respect of Interest Carryover Amounts other than
Interest Carryover Amounts resulting from the fact that this Agreement does not
allocate the Applied Realized Loss Amount to the Class A Certificates. Any
amounts received under the terms of the Cap Contract on a Distribution Date that
are not used to pay such Interest Carryover Amounts will be distributed to the
holder of the Class C Certificates. Payments in respect of such Interest
Carryover Amounts shall be paid to the Offered Certificates, pro rata based upon
such Interest Carryover Amounts for each class of Offered Certificates.

                  (i)      On or prior to the Cap Contract Termination Date,
         amounts, if any, received by the Trustee for the benefit of the Trust
         Fund in respect of the Cap Contract shall be deposited by the Trustee
         into the Cap Contract Account and will be used to pay Interest
         Carryover Amounts on the Offered Certificates (other than the Class S
         Certificates) other than Interest Carryover Amounts resulting from the
         fact that this Agreement does not allocate the Applied Realized Loss
         Amount to the Class A Certificates. Any amounts that are received on
         the Cap Contract that are not used to pay such Interest Carryover
         Amounts on the Offered Certificates (other than the Class S
         Certificates), will be distributed to the holder of the Class C
         Certificates. With respect to any Distribution Date on or prior to the
         Cap Contract Termination Date, the amount, if any, payable by the Cap
         Contract Counterparty under the Cap Contract will equal the product of
         (i) the excess of (x) One-Month LIBOR (as determined by the Cap
         Contract Counterparty and subject to a cap equal to 8.890%), over (y)

(1)      The Class P Certificates shall not have minimum dollar denominations or
         Certificate Principal Balances 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 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

                                      -87-
<PAGE>

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 a transfer of a Class C or Class P
Certificate to the indenture trustee under an Indenture pursuant to which NIM
Notes are issued, whether or not such notes are guaranteed by the NIMs Insurer)
each certify to 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 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
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, (ii) except in the case of a Class R Certificate which may not be
transferred to a transferee that does not provide the representation described
in clause (i), a representation that the transferee is an insurance company that
is purchasing such Certificates with funds contained in an "insurance company
general account" (as such term is defined in Section V(e) of Prohibited
Transaction Class Exemption 95-60, 60 Fed. Reg. 35925 (July 12, 1995) ("PTCE
95-60")) and that the purchase and holding of such Certificates is covered under
Sections I and III of PTCE 95-60, or (iii) 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

                                      -88-
<PAGE>

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 a representation
or an Opinion of Counsel satisfactory to the Trustee 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 in the form attached as Exhibit N (except with respect to the
transfer of a Class C Certificate to any trust which issues NIM Notes). 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 shall absolutely have no rights in
the purported Transferee.

         (c)      Each Person who has or who acquires any Ownership Interest in
a Class R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Class R
Certificate are expressly subject to the following provisions:

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

                  (ii)     No Ownership Interest in a Class R Certificate may be
         purchased, transferred or sold, directly or indirectly, without the
         express written consent of the Trustee. 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

                                      -89-
<PAGE>

         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 LTR Interest, the Class MTR Interest and the
         residual interest in the Upper Tier REMIC 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 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) 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
         LTR Interest, the Class MTR Interest and the residual interest in the
         Upper Tier REMIC shall be severed and represented by separate
         Certificates.

                                      -90-

         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, 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 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

                                      -91-
<PAGE>

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.

         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.

<PAGE>

         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 Trustee or 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
offices at Sixth and Marquette Avenue, Minneapolis, Minnesota 55479, Attention:
Corporate Trust Services - Merrill Lynch Mortgage Investors Inc., Series
2003-WMC3 as offices for such purposes. The Trustee will give prompt written
notice to the Certificateholders of any change in such location of any such
office or agency.

         SECTION 5.10. [RESERVED]

                                   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.

                                      -93-
<PAGE>

         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 (i) incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder or (ii) which does not constitute
an "unanticipated expense" within the meaning of Treasury Regulation Section
1.860G-1(b)(3). Neither the Depositor nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its respective duties hereunder and that in its opinion may
involve it in any expense or liability; provided, however, that any of the
Depositor or the Servicer may, in its discretion undertake any such action that
it may deem necessary or desirable in respect of this Agreement and the rights
and duties of the parties hereto and interests of the Servicer and the
Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom shall be, expenses, costs and
liabilities of the 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.

         Subject to the other provisions of this Agreement (including, but not
limited to, Sections 6.02 and 10.14 hereof), the Servicer shall neither assign
all or substantially all its rights under this Agreement or the servicing
hereunder nor delegate all or substantially all its duties hereunder or any
portion thereof, or

                                      -94-
<PAGE>

sell or otherwise dispose of all or substantially all of its property or assets
without, in each case, the prior written consent of the Trustee and the NIMS
Insurer, which consent shall not be unreasonably withheld; provided, that in
each case, there must be delivered to the Trustee and the NIMS Insurer a letter
from each Rating Agency (at the expense of the Servicer) to the effect that such
transfer of servicing or sale or disposition of assets will not result in a
qualification, withdrawal or downgrade of the then-current rating of any of the
Certificates or of the NIMS Notes. Notwithstanding the foregoing, the Servicer,
without the consent of the Trustee and the NIMS insurer, may retain third-party
contractors to perform certain servicing and loan administration functions,
including, without limitation, hazard insurance administration, tax payment and
administration, flood certification and administration, collection services and
similar functions; provided, however, that the retention of such contractors by
Servicer shall not limit the obligation of the Servicer to service the Mortgage
Loans pursuant to the terms and conditions of this Agreement. 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 Section 7.01 and 7.02 as obligations that survive the resignation or
termination of the 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 to
         remit to the Trustee any payment (excluding a payment required to be
         made under Section 4.01 hereof) required to be made under the terms of
         this Agreement, which failure shall continue unremedied for three
         Business Days and, with respect to a payment required to be made under
         Section 4.01 hereof, for one Business Day, after the date on which
         written notice of such failure shall have been given to the Servicer by
         the Trustee or the Depositor, or to the Trustee and the Servicer by the
         NIMs Insurer or the Holders of Certificates evidencing not less than
         25% of the Voting Rights evidenced by the Certificates; or

                                      -95-
<PAGE>

                  (ii)     any failure by the Servicer to observe or perform in
         any material respect any other of the covenants or agreements on the
         part of the Servicer contained in this Agreement or any representation
         or warranty shall prove to be untrue, which failure or breach shall
         continue unremedied for a period of 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 25% 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 25% 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, whether with respect to the Mortgage Loans or otherwise, shall pass
to and be vested in the Trustee. To the extent the Event of Default resulted
from the failure of the Servicer to make a required Advance, the Trustee shall
thereupon make any Advance described in Section 4.01 hereof subject to Section
3.04 hereof. The Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any and
all documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents, or otherwise. Unless expressly
provided in such written notice, no such termination shall affect any obligation
of the Servicer to pay amounts owed pursuant to Article VIII. The Servicer
agrees to cooperate with the Trustee in effecting the termination of the
Servicer's responsibilities and rights hereunder, including, without limitation,
the transfer to the Trustee of all cash amounts which shall at the time be
credited to the Collection Account, or thereafter be received with respect to
the Mortgage Loans. The Servicer and the Trustee shall promptly notify the
Rating Agencies 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

                                      -96-
<PAGE>

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. Trustee to Act; Appointment of Successor.

         On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 hereof, the Trustee shall, to the extent provided in
Section 3.04, be the successor to the Servicer in its capacity as servicer under
this Agreement and the transactions set forth or provided for herein and shall
be subject to all the responsibilities, duties and liabilities relating thereto
placed on the Servicer by the terms and provisions hereof and applicable law,
including the obligation to make advances pursuant to Section 4.01. As
compensation therefor, subject to the last paragraph of Section 7.01, the
Trustee shall be entitled to all fees, costs and expenses relating to the
Mortgage Loans that the Servicer would have been entitled to if the Servicer had
continued to act hereunder. Notwithstanding the foregoing, if the Trustee has
become the successor to the Servicer in accordance with Section 7.01 hereof, the
Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited
by applicable law from making Advances pursuant to Section 4.01 hereof or if it
is otherwise unable to so act, appoint, or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution the
appointment of which successor shall be approved by the NIMs Insurer and 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), 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 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.

                                      -97-
<PAGE>

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

         SECTION 7.03. Notification to Certificateholders.

         (a)      Upon any termination of or appointment of a successor to the
Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, the 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 to the
requirements of this Agreement. If any such instrument is found not to conform
to the requirements of this Agreement in a material manner, the Trustee shall
take action as it deems appropriate to have the instrument corrected, 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:

                  (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

                                      -98-
<PAGE>

         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 25% 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.

         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 Opinion of Counsel shall be full and complete authorization and
         protection in respect of any action taken or suffered or omitted by it
         hereunder in good faith and in accordance with such Opinion of Counsel;

                  (iii)    the Trustee shall not be liable, 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 25% of the Voting Rights of such Class;

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

                                      -99-
<PAGE>

                  (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.

         (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 and Expenses.

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

                                     -100-

         SECTION 8.06. Indemnification of Trustee.

         (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).

         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, in the
aggregate in any calendar year; provided, however, that such cap shall apply
only if NIM Notes have been issued and shall cease to apply after the date on
which any NIM Notes are paid in full 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

                                     -101-
<PAGE>

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.

         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 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; provided, the appointment of a co-trustee shall not
relieve the Trustee of its obligations hereunder. If the Servicer and the NIMs
Insurer shall not have joined in such appointment within 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:

                                     -103-
<PAGE>

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

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

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

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

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

         SECTION 8.12. Tax Matters.

         (a)      It is intended that each of the REMICs provided for herein
REMIC 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.
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 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

                                     -104-
<PAGE>

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, 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
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; (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) 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); (i) sign or
cause to be signed federal, state or local income tax or information returns;
(j) 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 (k) as and when necessary and appropriate,
represent each of the REMICs provided for herein in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year of
any of the REMICs provided for herein, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of any of the REMICs provided for herein, and otherwise act on behalf
of each of the REMICs provided for herein in relation to any tax matter
involving any of such REMICs or any controversy involving the Trust Fund.

         In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 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

                                     -105-
<PAGE>

the 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 (other than amounts
derived by the Trust Fund from a payment on the Cap Contract) 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 (other than the Class R Certificates) (pro rata). Notwithstanding
anything to the contrary contained herein, to the extent that such tax is
payable by the Class R Certificate, the Trustee is hereby authorized pursuant to
such instruction to retain on any Distribution Date, from the Holders of the
Class R Certificate (and, if necessary, from the Holders of all other
Certificates in the priority specified in the preceding sentence), funds
otherwise distributable to such Holders in an amount sufficient to pay such tax.
The Trustee agrees to promptly notify in writing the party liable for any such
tax of the amount thereof and the due date for the payment thereof.

         (b)      Each of the Depositor 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.

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

         Any termination by the Trustee pursuant to clause (a) above shall be
effected by the auction by the Trustee of all of the Mortgage Loans and REO
Properties via a solicitation of bids from at least three (3) bidders, each of
whom shall be a nationally recognized participant in mortgage finance. The
Trustee shall accept the highest such bid, provided that such bid equals or
exceeds the amount described in clause (i) of the definition of "Optional
Termination Price." The Depositor, the Trustee and the Servicer agree to work in
good faith to develop auction bid procedures to govern the operation of such an
auction. If the Trustee is unable to terminate the Trust Fund as a result of
such Optional Termination, failing to realize the amount described in clause (i)
of the definition of Optional Termination Price the NIMs Insurer may, at its
option, terminate the Trust Fund by purchasing all of the Mortgage Loans and REO
Properties at the

                                     -106-
<PAGE>

price equal to the amount described in clause (ii) of the definition of
"Optional Termination Price." Notwithstanding anything to the contrary herein,
the Optional Termination Amount paid to the Trustee by the winning bidder or by
the NIMs Insurer shall be deposited by the Trustee directly into the Certificate
Account immediately upon Optional Termination. Any Optional Termination Amount
to be paid by the NIMs Insurer may be paid by the NIMs Insurer to the Trustee
for deposit into the Certificate Account. Upon any termination pursuant to
clause (a) above, the Trustee shall pay to the Servicer, out of the Optional
Termination Amount deposited into the Certificate Account, the aggregate amount
of any unreimbursed out-of-pocket costs and expenses owed to the Servicer and
any unpaid or unreimbursed Servicing Fees, Advances and Servicing Advances.

         The right of the Trustee or the NIMs Insurer to effect an Optional
Termination pursuant to clause (a) above shall be conditioned upon the aggregate
outstanding Stated Principal Balance of the Mortgage Loans, at the time of any
such repurchase, aggregating ten (10) percent or less of the Stated Principal
Balance of the Mortgage Loans as of the Cut-off Date.

         The Class R Certificateholder hereby assigns to the Class C
Certificateholders that portion of any amount received by the Class R
Certificate upon an Optional Termination of the trust created hereunder that is
attributable to clause (i)(C) of the definition of Optional Termination Price
and required to cover what would otherwise be a shortfall in the amounts
described in clause (i)(C) of the definition of Optional Termination 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. If the Trustee elects to terminate the Trust Fund pursuant to clause
(a) of Section 9.01, 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.

         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

                                     -107-
<PAGE>

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 or the NIMs Insurer exercises its
option to effect an Optional Termination as provided in Section 9.01, the Trust
Fund shall be terminated in accordance with the following additional
requirements, unless the Trustee has been supplied with an Opinion of Counsel,
at the expense of the Trustee 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 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 Trustee 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.

                                     -108-
<PAGE>

         (c)      The Trustee as agent for each REMIC hereby agrees to adopt and
sign such a plan of complete liquidation upon the written request of the
Depositor, and the receipt of the 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 cure any ambiguity, to correct or
supplement any provisions herein, or to make such other provisions with respect
to matters or questions arising under this Agreement, as shall not be
inconsistent with any other provisions herein if such action shall not, as
evidenced by an Opinion of Counsel, adversely affect in any material respect the
interests of any Certificateholder; provided, however, that any such amendment
shall be deemed not to adversely affect in any material respect the interests of
the Certificateholders and no such Opinion of Counsel shall be required if the
Person requesting such amendment obtains a letter from each Rating Agency
stating that such amendment would not result in the downgrading or withdrawal of
the respective ratings then assigned to 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.

         Notwithstanding the foregoing, without the consent of the
Certificateholders but with the consent of the NIMs Insurer, 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,
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 each Class of Certificates affected
thereby evidencing not less than 66 2/3% of the Voting Rights of such Class,
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 anything to the contrary in this Agreement, 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 Certificateholders
evidencing not less than 66 2/3% of the Voting Rights of each Class of
Certificates

                                     -109-

(excluding the Voting Rights of the Depositor, its Affiliates or its agents) for
the purpose of significantly changing the Permitted Activities of the Trust.

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

         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

                                     -110-
<PAGE>

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 it has actual knowledge:

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

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

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

                  (iv)     The repurchase or substitution of Mortgage Loans
         pursuant to Sections 2.02, 2.03 and 3.12;

                  (v)      The final payment to Certificateholders; and

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

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

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

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

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

         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; Delegation of Duties.

         Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02 or 10.14, this Agreement may not be assigned
by the Servicer without the prior written consent of the Trustee and Depositor.
Except as otherwise contemplated by this Agreement (including Sections 3.02(a)
and 6.02), the Servicer may not delegate to any third party all or substantially
all of its duties and obligations under this Agreement without the prior written
consent of the Trustee and the Depositor.

         SECTION 10.08. Limitation on Rights of Certificateholders.

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

         No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth or contained in the terms of the Certificates be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall 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

                                     -112-
<PAGE>

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 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

                                     -113-
<PAGE>

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 their 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 related Servicer 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 Servicer under the applicable 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 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 Servicer
pursuant to the applicable 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.

         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) and (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 described in the preceding clauses (i), (ii) and
(iii), an "Advance Financing Person"), and/or (2) an Advance Financing Person
agrees to finance all the Advances and/or Servicing Advances required to be made
by the Servicer pursuant to this Agreement.

                                     -114-
<PAGE>

No consent of the Trustee, Certificateholders or any other party shall be
required before the Servicer may enter into an Advance Facility nor shall the
Trustee or the Certificateholders be a third party beneficiary of any obligation
of an Advance Financing Person to the Servicer. Notwithstanding the existence of
any Advance Facility under which an Advance Financing Person agrees to fund
Advances and/or Servicing Advances, (A) the Servicer (i) shall remain obligated
pursuant to this Agreement to make Advances and/or Servicing Advances pursuant
to and as required by this Agreement and (ii) shall not be relieved of such
obligations by virtue of such Advance Facility and (B) neither the Advance
Financing Person nor any Servicer's Assignee (as hereinafter defined) shall have
any right to proceed against or otherwise contact any Mortgagor for the purpose
of collecting any payment that may be due with respect to any related Mortgage
Loan or enforcing any covenant of such Mortgagor under the related mortgage loan
documents.

         (b)      If the Servicer enters into an Advance Facility, the Servicer
and the related Advance Financing Person shall deliver to the Trustee at the
address set forth in Section 10.05 hereof a written 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 receive amounts available 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 Facility Person, 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
and the Servicer acting jointly (unless the Servicer has previously notified the
Trustee in writing that the documentation for such Advance Facility provides
that such entitlement may be terminated by the Advance Financing Person alone)
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, an Advance Financing Person shall only be entitled to reimbursement
of Advance Reimbursement Amounts hereunder pursuant to Section 3.08 and/or 4.01
of this Agreement and shall not otherwise be entitled to receive amounts
designated for distribution to Certificateholders pursuant to Section 3.08
and/or 4.01 hereof. None of the Trustee or the Certificateholders shall have any
right to, or otherwise be entitled to, receive any amounts which constitute
Advance Reimbursement Amounts designated for reimbursement or distribution to
the Servicer pursuant to Section 3.08 and/or 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 from any loss or liability 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, or failure by the successor servicer or the Trustee to remit funds as
required by

                                     -115-
<PAGE>

this Agreement or the commission of an act or omission to act by the successor
servicer or the Trustee, 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)      [RESERVED].

         (e)      As between a predecessor Servicer and its Advance Financing
Person, on the one hand, and a successor Servicer and its Advance Financing
Person if any, on the other hand, Advance Reimbursement Amounts on a
loan-by-loan basis with respect to each Mortgage Loan as to which an Advance
and/or Servicing Advance shall have been made and be outstanding shall be
allocated on a "first-in, first out" basis. In the event the Servicer's Assignee
shall have received some or all of an Advance Reimbursement Amount related to
Advances and/or Servicing Advances that were made by a Person other than such
predecessor Servicer or its related Advance Financing Person in error, then such
Servicer's Assignee shall be required to remit any portion of such Advance
Reimbursement Amount to each Person entitled to such portion of such Advance
Reimbursement Amount. Without limiting the generality of the foregoing, the
Servicer shall remain entitled to be reimbursed by the Advance Financing Person
for all Advances and/or Servicing Advances funded by the Servicer to the extent
the related Advance Reimbursement Amounts have not been assigned or pledged to
such Advance Financing Person or Servicer's Assignee.

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

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

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

         2003-OPT1, Class R on behalf of a disqualified organization or any
         other entity,

(4)      unless Merrill Lynch Mortgage Investors, ("MLMI") has consented to the

         Appendix B to the Transferee's Letter to which this Certificate is
         affixed as Appendix A, the Transferee is a "U.S. person" (as defined
         below),

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

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

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

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

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

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

         disqualified organization, and

(11)     IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE [the

         Certificate to a foreign permanent establishment or fixed base (within
         the meaning of an applicable income tax treaty) of the Transferee, and
         as to each of the residual interests represented by the Class R

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

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

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

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

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

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

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

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