                                      -54-
<PAGE>

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

      With respect to any Mortgage Loan that is not a Co-op Loan, none of the
Depositor, the Master Servicer, the Servicer, the Securities Administrator 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. In the event that any
Assignment of Mortgage referred to in this Section 2.01 is not recorded or is
improperly recorded, the Servicer and the Trustee shall have no liability for
any failure to receive or act on notices related to such Assignment of Mortgage.

      The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. None of the Depositor, the Master Servicer, the Servicer or
the Securities Administrator shall take any action inconsistent with such
ownership and shall not claim any ownership interest therein. The Depositor, the
Master Servicer, the Servicer and Securities Administrator 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

                                      -55-
<PAGE>

to the satisfaction of the claims of any Person in any Certificates, the
security interest created hereby shall continue in full force and effect and the
Trustee shall be deemed to be the collateral agent for the benefit of such
Person.

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

      Section 2.02. Acceptance by the Trustee of the Mortgage Loans.

      Except as set forth in the Exception Report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it holds and
will hold such documents and any other documents constituting a part of the
Mortgage Files delivered to it in trust for the use and benefit of all present
and future Certificateholders. The Depositor will cause the 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 four Cap Contracts (forms of which
are attached hereto as Exhibits N-1, N-2, N-3 and N-4), the Transfer Agreement,
the Bring Down Letter and the Sale Agreement.

      The Trustee agrees, for the benefit of Certificateholders and the NIMs
Insurer, to review or cause its Custodian 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, the Master
Servicer and the Servicer that all documents required by Section 2.01 have been
executed and received, and that such documents relate to the Mortgage Loans
identified in Exhibit B that have been conveyed to it. If the Trustee finds any
document or documents constituting a part of a Mortgage File to be missing or
defective (that is, mutilated, damaged, defaced or unexecuted) in any material
respect, the Trustee shall promptly (and in any event within no more than five
Business Days) after such finding so notify the NIMs Insurer, the Servicer, the
Master Servicer, the Seller and the Depositor. In addition, the Trustee shall
also notify the NIMs Insurer, the Master Servicer, the Servicer, the Seller and
the Depositor if the original Mortgage with evidence of recording thereon with
respect to a Mortgage Loan is not received within 70 days of the Closing Date;
if it has not been received because of a delay caused by the public recording
office where such Mortgage has been delivered for recordation, the Depositor
shall deliver or cause to be delivered to the Trustee written notice stating
that such Mortgage has been delivered to the appropriate public recording office
for recordation and thereafter the Depositor shall deliver or cause to be
delivered such Mortgage with evidence of recording thereon upon receipt thereof
from the public recording office. The Trustee shall request that the Seller
correct or cure such omission, defect or other irregularity, or substitute a
Mortgage Loan pursuant to the provisions of Section 2.03,

                                      -56-
<PAGE>

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 Certificate Account or
Collection Account, as appropriate, promptly upon receipt, and, upon receipt by
the Trustee of written notification of such deposit signed by a Servicing
Officer, 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 requested by the Seller and 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 NIMs
Insurer, the Depositor or the Trustee pursuant to the Sale Agreement, the
Transfer Agreement and the Bring Down Letter. The Trustee shall be under no duty
or obligation to inspect, review and examine such documents, instruments,
certificates or other papers to determine that they are genuine, enforceable,
recordable or appropriate to the represented purpose, or that they have actually
been recorded, or that they are other than what they purport to be on their
face. The Servicer, the Master Servicer, the Securities Administrator and the
Trustee shall keep confidential the name of each Mortgagor except as required by
this Agreement and the Servicer, the Master Servicer, the Securities
Administrator and the Trustee shall not solicit any such Mortgagor for the
purpose of refinancing the related Mortgage Loan; notwithstanding anything
herein to the contrary, the foregoing shall not be construed to prohibit (i)
disclosure of any and all information that is or becomes publicly known, or
information obtained by the Trustee, the Servicer, the Master Servicer or the
Securities Administrator from sources other than the other parties hereto, (ii)
disclosure of any and all information (A) if required by any applicable law,
rule or regulation, (B) to any government agency or regulatory body having or
claiming authority to regulate or oversee any aspects of the Trustee's business
or that of its affiliates, (C) pursuant to any subpoena, civil investigation
demand or similar demand or request of any court, regulatory authority,
arbitrator or arbitration to which Trustee or any affiliate or an officer,
director, employer or shareholder thereof is a party or (D) to any affiliate,
independent or internal auditor, agent, employee or attorney of the Trustee, the
Servicer, the Master Servicer or the Securities Administrator having a need to
know the same, provided that the Trustee, the Servicer, the Master Servicer or
the Securities Administrator, as applicable, advises such recipient of the
confidential nature of the information being disclosed, or (iii) any other
disclosure authorized by the Depositor. 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 (or its custodian) shall
deliver to the NIMs Insurer, the Depositor, the Master Servicer and the Servicer
the Trustee's Certification, substantially in the form of Exhibit D attached
hereto, evidencing the completeness of the Mortgage Files, with any exceptions
noted thereto.

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

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

                                      -57-
<PAGE>

            (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
      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 Mortgage Loans contained in the Transfer Agreement were made as
of the date of the Transfer Agreement and brought forward to the Closing Date
pursuant to the Bring Down Letter. The representations and warranties of the
Transferor with respect to the Mortgage Loans contained in the

                                      -58-
<PAGE>

Bring Down Letter were made as of the Closing Date. The representations and
warranties of the Seller with respect to the Mortgage Loans contained in the
Sale Agreement were made as of the Closing Date.

      To the extent that any fact, condition or event with respect to a Mortgage
Loan constitutes a breach of a representation or warranty of the Transferor
under the Transfer Agreement (whether or not such fact, condition or event would
also constitute a breach of a representation or warranty of the Seller under the
Sale Agreement), the only rights or remedies of the Trustee, the NIMs Insurer or
of any Certificateholder shall be first, the Trustee's right to enforce the
obligations of the Transferor under such applicable representation or warranty
made by it and, second, only if the Transferor is unable or unwilling to fulfill
its obligations to cure or repurchase such Mortgage Loan, the Trustee shall
exercise its right to enforce any rights it may have against the Seller under
the Sale Agreement with respect to such representation or warranty; provided,
that in the event the Trustee shall have received a copy of any Transferor
Affirmation Notice, the Trustee shall only be entitled to enforce any rights it
has against the Transferor under the Transfer Agreement and shall not have any
rights against the Seller under the Sale Agreement with respect to such
representation or warranty. To the extent that any fact, condition or event with
respect to a Mortgage Loan constitutes a breach of a representation or warranty
made by the Seller in the Sale Agreement that does not also constitute a breach
of a representation or warranty of the Transferor under the Transfer Agreement,
the Trustee shall enforce any rights it may have against the Seller under the
Sale Agreement. In furtherance of the above, the Seller expressly acknowledges
that prior to the issuance of a Transferor Affirmation Notice, it shall be
obligated and liable to the Trustee, the NIMs Insurer and the Certificateholders
for any breach of a representation or warranty made under the Transfer
Agreement, but only after the Transferor evidences that it is unwilling or
unable to fulfill its contractual obligations under the Transfer Agreement. The
Trustee acknowledges that the Depositor shall have no obligation or liability
with respect to any breach of any representation or warranty with respect to the
Mortgage Loans (except as set forth in Section 2.03(a)(v)) under any
circumstances.

      In addition to the representations and warranties of the Transferor in the
Transfer Agreement that were brought forward to the Closing Date pursuant to the
Bring Down Letter, with respect to each Mortgage Loan, the Transferor made
certain additional covenants regarding such Mortgage Loan, as set forth in the
Transfer Agreement. With respect to any breach of such additional covenants that
materially and adversely affects the interests of the Certificateholders in such
Mortgage Loan, the Seller shall (1) use reasonable efforts to enforce such
covenant against the Transferor and (2) if the Seller successfully enforces any
obligation of the Transferor to repurchase such Mortgage Loan, the Seller shall
repurchase such Mortgage Loan in accordance with this Section 2.03. If the
Seller does not successfully enforce the obligation, if any, of the Transferor
to repurchase a Mortgage Loan with respect to any breach of any such additional
covenants, the Seller shall have no obligation or right to repurchase or cure
such Mortgage Loan.

            (c) Upon discovery by any of the Depositor, the Master Servicer, the
Securities Administrator, the Servicer, 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 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

                                      -59-
<PAGE>

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). As
provided in the Sale Agreement, if the Transferor substitutes for a Mortgage
Loan for which there is a breach of any representations and warranties in the
Transfer Agreement which adversely and materially affects the value of such
Mortgage Loan and such substitute mortgage loan is not a Replacement Mortgage
Loan, under the terms of the Sale Agreement, the Seller will, in exchange for
such substitute Mortgage Loan, (i) provide the applicable Purchase Price for the
affected Mortgage Loan or (ii) within two years of the Closing Date, substitute
such affected Mortgage Loan with a Replacement Mortgage Loan. Any such
substitution shall not be effected prior to the additional delivery to the
Trustee of a Request for Release substantially in the form of Exhibit I and
shall not be effected unless it is within two years of the Startup Day. As
provided in the Sale Agreement, the Seller indemnifies and holds the Trust Fund,
the Trustee, the Depositor, the NIMs Insurer, the Master Servicer, the
Securities Administrator, 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 Master Servicer, the Securities Administrator, 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 day" under Section 860G(d)(1) of the Code, or
(ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding. In furtherance of the foregoing, if the Seller
is not a member of MERS and repurchases a Mortgage Loan which is registered on
the MERS System, the Seller, at its own expense and without any right of
reimbursement, shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and
shall cause such Mortgage to be removed from registration on the MERS System in
accordance with MERS' rules and regulations.

      With respect to any Mortgage Loan repurchased by the 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 Servicer in respect of such repurchase of a Mortgage Loan
will be considered a Principal Prepayment and shall be deposited by the Servicer
in the Collection Account pursuant to Section 3.05 and the Servicer shall notify
the Securities Administrator of its receipt of the same. The Trustee, upon
receipt of notice from the Servicer of its 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 (or its custodian), and neither the Trustee nor the
Securities Administrator shall not have any further responsibility with respect
to the Mortgage File relating to such Deleted Mortgage Loan.

                                      -60-
<PAGE>

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

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

      The Trustee shall cause the Mortgage Loan Schedule 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, the Servicer, the
Master Servicer 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.

            (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

                                      -61-

Depositor hereunder shall each survive delivery of the Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue
throughout the term of this Agreement.

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

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

      Upon discovery by the Depositor, the Master Servicer, the Servicer, the
Securities Administrator 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, upon the
written request of the Depositor, 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 Securities
Administrator 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 Securities Administrator in authorized denominations
evidencing ownership of the entire Trust Fund. The Trustee agrees to hold the
Trust Fund and exercise the rights referred to above for the benefit of all
present and future Holders of the Certificates and to perform its duties set
forth in this Agreement in accordance with the provisions hereof to the best of
its abilities, to the end that the interests of the Holders 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 and the Lower
Tier REMIC as a REMIC. The Trustee, upon written direction of the Securities
Administrator, 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 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 Day" for purposes of the REMIC Provisions shall be
the Closing Date. Each REMIC's fiscal year shall be the calendar year.

                                      -65-
<PAGE>

      The Lower Tier REMIC shall consist of all of the assets of the Trust Fund,
other than (i) amounts distributable to the Class P Certificates pursuant to
Section 4.04(b)(i) hereof, (ii) the interests issued by the Lower Tier REMIC,
(iii) the grantor trusts described in Section 2.07 hereof and (iv) each Cap
Contract and the Cap Contract Account. The Lower Tier REMIC shall issue the
Lower Tier REMIC Regular Interests which shall be designated as regular
interests of such REMIC and shall issue the Class LTR Interest 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.

      The assets of the Upper Tier REMIC shall be the Lower Tier REMIC Regular
Interests. The REMIC Regular Interests shall be designated as the regular
interests in the Upper Tier REMIC and the Residual Interest shall be designated
as the sole class of residual interest in the Upper Tier REMIC. For federal
income tax purposes, (i) the pass-through rate on the REMIC Regular Interests
represented by the Class A-1 Certificates and on the sole class of residual
interest in the Upper Tier REMIC shall be subject to a cap equal to the Class
A-1 Available Funds Cap; (ii) the pass-through rate on the REMIC Regular
Interests represented by the Class A-2 Certificates shall be subject to a cap
equal to the Class A-2 Available Funds Cap; and (iii) the pass-through rate on
the REMIC Regular Interests represented by the Class A-3 Certificates and the
Subordinate Certificates shall be subject to a cap equal to the Weighted Average
Available Funds Cap.

      The beneficial ownership of the Class LTR 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.

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

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

            (e) The parties intend that the portion of the Trust Fund consisting
of the Uncertificated Class C Interest, the Cap Contracts, the Cap Contract
Account, and the obligation of the

                                      -66-
<PAGE>

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

            (f) The parties intend that the portion of the Trust Fund consisting
of the right to receive amounts distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class P Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Securities Administrator 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) [RESERVED]

            (h) All payments of principal and interest at the Net Mortgage Rate
on each of the Mortgage Loans (other than amounts distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof) received 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, payments and
losses shall be allocated among the Lower Tier REMIC Regular Interests so that
(i) each of the Lower Tier REMIC I Marker Interests shall have a principal
balance equal to 25% of the principal balance of the Corresponding Certificates,
(ii) the Class LTIX Interest has a principal balance equal to the excess of (x)
50% of the remaining principal balance of the Mortgage Loans over (y) the
aggregate principal balance of the Lower Tier REMIC I Marker Interests (if
necessary to reflect an increase in overcollateralization, accrued and unpaid
interest on the Class LTIX interest may be added to its principal amount to
achieve this result) and (iii) the aggregate principal amount of the Class
LTII1A Interest, Class LTII1B Interest, Class LTII2A Interest, Class LTII2B
Interest and the Class LTIIX Interest shall equal 50% of the remaining principal
balance of the Mortgage Loans. Distributions and losses allocated to the Lower
Tier REMIC Regular Interests described in clause (iii) of the preceding sentence
will be allocated among such Lower Tier REMIC Regular Interests in the following
manner: (x) such distributions shall be deemed made to such Lower Tier REMIC
Regular Interests first, so as to keep the principal balance of the each such
Lower Tier REMIC Regular Interest with "B" at the end of its designation equal
to 0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
the related Mortgage Group and second, to such Lower Tier REMIC Regular
Interests with "A" at the end of its designation so that the uncertificated
principal balance of each such Lower Tier REMIC Regular Interest is equal to
0.05% of the excess of (I) the aggregate scheduled principal balance of the
Mortgage Loans in the related Mortgage Group over (II) the aggregate principal
balance of Certificate Group One, in the case of the Class LTII1A Interest, or
Certificate Group Two, in the case of the Class LTII2A Interest (except that if
0.05% of any such excess is greater than the principal amount of the related
Lower Tier REMIC II Marker Interest with "A" at the end of its designation, the
least amount of principal shall be distributed to each Lower Tier REMIC II
Marker Interest with "A" at the end of its designation such that the Lower Tier
REMIC Subordinated Balance Ratio is maintained) and finally, any remaining
distributions of principal to the Class LTIIX

                                      -67-
<PAGE>

Interest and (y) such losses shall be allocated among the Lower Tier REMIC
Regular Interests described in clause (iii) of the preceding sentence first, so
as to keep the principal balance of the each such Lower Tier REMIC Regular
Interest with "B" at the end of its designation equal to 0.05% of the aggregate
scheduled principal balance of the Mortgage Loans in the related Mortgage Group;
second, to such Lower Tier REMIC Regular Interests with "A" at the end of its
designation so that the uncertificated principal balance of each such Lower Tier
REMIC Regular Interest is equal to 0.05% of the excess of (I) the aggregate
scheduled principal balance of the Mortgage Loans in the related Mortgage Group
over (II) the aggregate principal balance of Certificate Group One, in the case
of the Class LTII1A Interest, or Certificate Group Two, in the case of the Class
LTII2A Interest (except that if 0.05% of any such excess is greater than the
principal amount of the related Lower Tier REMIC II Marker Interest with "A" at
the end of its designation, the least amount of losses shall be allocated to
each Lower REMIC II Marker Interest with "A" at the end of its designation such
that the Lower Tier REMIC Subordinated Balance Ratio is maintained) and finally,
any remaining losses to the Class LTIIX Interest. Notwithstanding the preceding
two sentences, however, losses not allocated to any Class of Certificates will
not be allocated to any Lower Tier REMIC Regular Interests. All computations
with respect to the Lower Tier REMIC Regular Interests shall be taken out to ten
decimal places.

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

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

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

            (i) In the event that any REMIC provided for herein fails to qualify
as a REMIC, loses its status as a REMIC or incurs federal, state or local taxes
as a result of a prohibited transaction or prohibited contribution under the
REMIC Provisions due to the negligent performance by the Servicer of its duties
and obligations set forth herein, the Servicer shall indemnify the NIMs Insurer,
the Trustee, the Securities Administrator, the Master Servicer and the Trust
Fund against any and all Losses resulting from such negligence; provided,
however, that the Servicer shall not be liable for any such Losses

                                      -68-

attributable to the action or inaction of the Trustee, the Securities
Administrator, the Master Servicer, the Depositor or the Holder of the residual
interest in such REMIC, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of the residual interest in such REMIC on
which the Servicer has relied. The foregoing shall not be deemed to limit or
restrict the rights and remedies of the Holder of the residual interest in such
REMIC now or hereafter existing at law or in equity. Notwithstanding the
foregoing, however, in no event shall the Servicer have any liability (1) for
any action or omission that is taken in accordance with and in compliance with
the express terms of, or which is expressly permitted by the terms of, this
Agreement, (2) for any Losses other than those arising out of a negligent
performance by the Servicer of its duties and obligations set forth herein, and
(3) for any special or consequential damages to Certificateholders (in addition
to payment of principal and interest on the Certificates).

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

      Section 2.08. [RESERVED]

      Section 2.09. Covenants of the Servicer.

      The Servicer hereby covenants to each of the other parties to this
Agreement as follows:

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

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

      Section 2.10. [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

                                      -69-
<PAGE>

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 Contracts, an
insurance and indemnity agreement with a NIMs Insurer and any other agreement or
instrument related thereto, in each case in such form as the Depositor shall
direct or shall approve, 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

shall be limited in accordance with paragraph 35 thereof.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

      Section 3.01. Servicer to Service Mortgage Loans.

      For and on behalf of the Certificateholders, the Servicer shall service
and administer the Mortgage Loans, including without limitation, any powers of
attorney, 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. The Servicer shall not make or permit any modification,
waiver or amendment of any term of any Mortgage Loan which would cause any of
the REMICs provided for herein to fail to qualify as a REMIC or result in the
imposition of any tax under Section 860G(a) or 860G(d) of the Code. The Servicer
shall represent and protect the interest of the Trust Fund in the same manner as
it currently protects its own interest in mortgage loans in its own portfolio in
any claim, proceeding or litigation regarding a Mortgage Loan, but in any case
not in any manner that is a lesser standard than that provided in the first
sentence of this Section 3.01. Without limiting the generality of the foregoing,
the Servicer, in its own name or in the name of the Depositor and the Trustee,
is hereby authorized and empowered by the Depositor and the Trustee, when the
Servicer believes it appropriate in its reasonable judgment, to execute and
deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any
of them, any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge, subordinations and all other comparable
instruments, with respect to the Mortgage Loans, and with respect to the
Mortgaged Properties held for the benefit of the Certificateholders. The
Servicer shall prepare and deliver to the Depositor, the Securities
Administrator 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, the
Securities Administrator and/or the Trustee shall execute such

                                      -70-
<PAGE>

documents and deliver them to the Servicer. For purposes of this Section 3.01,
the Trustee hereby grants to the Servicer a limited power of attorney in the
form of Exhibit P to execute and file any and all documents necessary to fulfill
the obligations of the Servicer under this Section 3.01.

      The Trustee shall deliver Powers of Attorney in the form attached hereto
as Exhibit P to the Servicer promptly after the Closing Date and additional
Powers of Attorney promptly after request therefor by 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. To the extent that a Mortgage does not provide for
escrow payments, (i) the Servicer shall determine whether any such payments are
made by the Mortgagor in a manner and at a time that is necessary to avoid the
loss of the Mortgaged Property due to a tax sale or to foreclosure as a result
of a tax lien and (ii) the Servicer shall ensure that all insurance required to
be maintained on the Mortgaged Property pursuant to this Agreement is
maintained. If any such payment has not been made and the Servicer receives
notice of a tax lien being imposed with respect to the Mortgage Loan, the
Servicer will, to the extent required to avoid loss of the Mortgaged Property,
advance or cause to be advanced funds necessary to discharge such lien on the
Mortgaged Property.

      All costs incurred by the Servicer, if any, in effecting the timely
payments of taxes and assessments on the Mortgaged Properties and related
insurance premiums shall not, for the purpose of calculating monthly
distributions to the Certificateholders, be added to the Stated Principal
Balance under the related Mortgage Loans, notwithstanding that the terms of such
Mortgage Loans so permit.

      In the event that the Mortgage Loan Documents relating to any Mortgage
Loan contain provisions requiring the related Mortgagor to submit to binding
arbitration any disputes arising in connection with such Mortgage Loan, the
Servicer shall be entitled to waive any such provisions on behalf of the Trust
and to send written notice of such waiver to the related Mortgagor, although the
Mortgagor may still require arbitration of such disputes at its option.

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

      The Servicer shall have at least 30 days' notice of the appointment of a
NIMs Insurer prior to being required to deliver any notices pursuant to this
Agreement to such NIMs Insurer.

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

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

      The Servicer further is authorized and empowered by the Trustee, on behalf
of the Certificateholders and the Trustee, in its own name or in the name of the
Sub-Servicer, when the Servicer or the Sub-Servicer, as the case may be,
believes it is appropriate in its best judgment to register any Mortgage Loan on
the MERS System, or cause the removal from the registration of any Mortgage Loan
on the MERS System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of

                                      -71-
<PAGE>

them, any and all instruments of assignment, release and other comparable
instruments with respect to such assignment, release or re-recording of a
Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns. Any reasonable expenses incurred in connection with the
actions described in the preceding sentence or as a result of MERS discontinuing
or becoming unable to continue operations in connection with the MERS System,
shall be subject to withdrawal by the Servicer from the Collection Account
(provided that such expenses constitute "unanticipated expenses" within the
meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii)).

      In connection with any modification pursuant to this Section and to the
extent there are any unreimbursed Advances or Servicing Advances, the Servicer
shall reimburse itself for such amounts from the Collection Account.

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

            (a) The Servicer may arrange for the subservicing of any Mortgage
Loan by a subservicer, which may be an affiliate (each, a "subservicer")
pursuant to a Subservicing Agreement (each, a "Subservicing Agreement");
provided, however, that (i) such subservicing arrangement and the terms of the
related Subservicing Agreement must provide for the servicing of such Mortgage
Loans in a manner consistent with the servicing arrangements contemplated
hereunder, (ii) that such agreement would not result in a withdrawal or
downgrading by any Rating Agency of the ratings of any Certificates or any of
the NIM Notes evidenced by a letter to that effect delivered by each Rating
Agency to the Depositor and the NIMs Insurer and (iii) the NIMs Insurer shall
have consented to such Subservicing Agreement, which consent shall not be
unreasonably withheld. Notwithstanding the provisions of any Subservicing
Agreement, any of the provisions of this Agreement relating to agreements or
arrangements between the Servicer and a subservicer or reference to actions
taken through a subservicer or otherwise, the Servicer shall remain obligated
and liable to the Depositor, the Master Servicer, the Trustee and the
Certificateholders for the servicing and administration of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such Subservicing Agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Mortgage Loans. Every Subservicing
Agreement entered into by the Servicer shall contain a provision giving any
successor servicer the option to terminate such agreement, with the consent of
the NIMs Insurer (which consent shall not be unreasonably withheld), in the
event a successor servicer is appointed. All actions of the each subservicer
performed pursuant to the related Subservicing Agreement shall be performed as
an agent of the Servicer with the same force and effect as if performed directly
by the Servicer. The Servicer shall deliver to the NIMs Insurer and the Master
Servicer copies of all Subservicing Agreements. The Trustee, the Master Servicer
and the Securities Administrator shall have no obligations, duties or
liabilities with respect to a subservicer, including, without limitation, any
obligation, duty or liability to monitor such subservicer or to pay a
subservicer's fees and expenses. Any subservicer or other subcontractor that
performs any of the functions indentified in Item 1122(d) of Regulation AB must
agree in writing that, if the Servicer or the Depositor determines that such
subcontractor was "participating in the servicing function" within the meaning
of Item 1122, such subcontractor will comply with the provisions of Sections
3.17 and 3.18 to the same extent as if it were the Servicer.

            (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, the Securities Administrator and
the Trustee in Respect of the Servicer.

      None of the Securities Administrator, the Trustee or the Depositor shall
have any responsibility or liability for any action or failure to act by the
Servicer, and none of them is obligated to supervise the performance of the
Servicer hereunder or otherwise.

<PAGE>

      Section 3.04. Master Servicer to Act as Servicer.

      Subject to Sections 6.04, 7.03 and 11.02, in the event that the Servicer
shall, for any reason, no longer be the servicer hereunder (including by reason
of an Event of Default), the Master Servicer 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 Master Servicer
shall not be (i) liable for losses of the Servicer pursuant to Section 3.10
hereof or any acts or omissions of any 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
Master Servicer (subject to clause (ii) above) 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 Master
Servicer (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 Master Servicer
(or any other successor servicer) shall not incur any liability or have any
obligations in its capacity as servicer under a subservicing agreement arising
prior to the date of such succession unless it expressly elects to succeed to
the rights and obligations of the Servicer thereunder; and the Servicer shall
not thereby be relieved of any liability or obligations under the subservicing
agreement arising prior to the date of such succession. To the extent any costs
or expenses, including without limitation Servicing Transfer Costs incurred by
the Master Servicer in connection with this Section 3.04 or Section 11.02, are
not paid by the Servicer pursuant to this Agreement within 30 days of the date
of the Master Servicer's invoice thereof, 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 Master Servicer is
unwilling or unable to act as servicer, the Master Servicer shall seek to
appoint a successor servicer that is eligible in accordance with the criteria
specified in this Agreement and reasonably acceptable to the NIMs Insurer.

      The Servicer shall, upon request of the Master Servicer, 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.

      Notwithstanding anything to the contrary above, the Trustee and the
Depositor hereby agree that within 10 Business Days of delivery to the Trustee
by the Servicing Rights Pledgee of a letter signed by the Servicer whereby the
Servicer shall resign as Servicer under this Agreement, the Servicing Rights
Pledgee or its designee shall be appointed as successor servicer (provided that
at the time of such appointment the Servicing Rights Pledgee or such designee
meets the requirements of a successor servicer set forth in Section 7.03 of this
Agreement) and the Servicing Rights Pledgee agrees to be subject to the terms of
this Agreement.

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

                                      -73-
<PAGE>

            (a) The Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing and subject to Section
3.01, the Servicer may in its discretion (i) waive any late payment charge or,
if applicable, any default interest charge, or (ii) extend the due dates for
payments due on a Mortgage Note for a period not greater than 180 days;
provided, however, that any extension pursuant to clause (ii) above shall not
affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below; provided, further, that the
NIMs Insurer's prior written consent shall be required for any modification,
waiver or amendment after the Cut-off Date if the aggregate number of
outstanding Mortgage Loans which have been modified, waived or amended exceeds
5% of the number of Mortgage Loans as of the Cut-Off Date. In the event of any
such arrangement pursuant to clause (ii) above, subject to Section 4.01, the
Servicer shall make any Advances on the related Mortgage Loan during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of the Servicer, such default is reasonably foreseeable, the
Servicer, consistent with the standards set forth in Section 3.01, may also
waive, modify or vary any term of such Mortgage Loan (including modifications
that would change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of such Mortgage Loan), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of such Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor (any and all such waivers, modifications, variances,
forgiveness of principal or interest, postponements, or indulgences collectively
referred to herein as "forbearance"), provided, however, that in no event shall
the Servicer grant any such forbearance (other than as permitted by the second
sentence of this Section) with respect to any one Mortgage Loan more than once
in any 12 month period or more than three times over the life of such Mortgage
Loan, and provided, further, that in determining which course of action
permitted by this sentence it shall pursue, the Servicer shall adhere to the
standards of Section 3.01. In connection with any modification pursuant to this
Section 3.05(a) and to the extent there are any unreimbursed Advances, the
Servicer shall reimburse itself for such amounts from the Collection Account.

            (b) The Servicer will not waive any Prepayment Charge or portion
thereof unless, (i) the enforceability thereof shall have been limited by
bankruptcy, insolvency, moratorium, receivership and other similar laws relating
to creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) in the Servicer's
reasonable judgment as described in Section 3.01 hereof, (x) such waiver relates
to a default or a reasonably foreseeable default, (y) such waiver would maximize
recovery of total proceeds taking into account the value of such Prepayment
Charge and related Mortgage Loan and (z) doing so is standard and customary in
servicing similar Mortgage Loans (including any waiver of a Prepayment Charge in
connection with a refinancing of a Mortgage Loan that is related to a default or
a reasonably foreseeable default), or (iv) sufficient information is not made
available to enable it to collect the Prepayment Charge. Except as provided in
the preceding sentence, in no event will the Servicer waive a Prepayment Charge
in connection with a refinancing of a Mortgage Loan that is not related to a
default or a reasonably foreseeable default. If the Servicer waives or does not
collect all or a portion of a Prepayment Charge relating to a Principal
Prepayment in full or in part due to any action or omission of the Servicer,
other than as provided above, the Servicer shall deposit the amount of such
Prepayment Charge (or such portion thereof as had been waived for deposit) into
the Collection Account for distribution in accordance with the terms of this
Agreement.

                                      -74-

            (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 maintain so long as it is
acting as servicer hereunder, on behalf of the Trustee for the benefit of the
Certificateholders, the Collection Account. The Servicer shall deposit into the
Collection Account, within two Business Days of receipt thereof, in immediately
available funds, the following payments and collections received or made by it
on and after the Cut-Off Date with respect to the Mortgage Loans:

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

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

                  (iii) all Liquidation Proceeds, other than proceeds to be
applied to the restoration or repair of the Mortgaged Property (or 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 Subsequent Recoveries;

                  (v) all Compensating Interest;

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

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

                  (viii) all Purchase Prices and Substitution Adjustment
Amounts;

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

                  (x) all Prepayment Charges;

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

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

      The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, all servicing-related fees,
including all late payment charges, insufficient funds charges, customary real
estate referral fees 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

                                      -75-
<PAGE>

in the case of a Co-op Loan), modification fees, extension fees and other
similar ancillary fees and charges (other than Prepayment Charges) if collected,
and any Prepayment Interest Excess need not be remitted by the Servicer. Rather,
such fees and charges 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, the Securities
Administrator 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 Securities Administrator, the Trustee and
the Depositor the most current available bank statement for the Collection
Account. Copies of such statement shall be provided by the Securities
Administrator to any Certificateholder and to any Person identified to the
Securities Administrator 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 Securities Administrator.

            (e) The Securities Administrator shall establish and maintain, on
behalf of the Certificateholders, the Certificate Account. The Securities
Administrator 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 Securities
Administrator pursuant to Section 3.05(g) in connection with any losses on
Permitted Investments; and

                  (iii) the Optional Termination Amount received by the
Securities Administrator pursuant to Section 9.01.

      Any amounts received by the Securities Administrator prior to 1:00 p.m.
New York City time (or such earlier deadline for investment in the Permitted
Investments designated by the Securities Administrator) which are required to be
deposited in the Certificate Account by the Servicer or Master 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 Master
Servicer and deposit by the Servicer and Master Servicer into the Certificate
Account shall be exclusive. In the event that the Servicer or the Master
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 Securities Administrator 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 Securities Administrator incur
liability for withdrawals from the Certificate Account at the direction of the
Servicer or the Master Servicer. The Securities Administrator shall give notice
to the NIMs Insurer, the Master Servicer and the Servicer of the location of the
Certificate Account maintained by it when established and prior to any change
thereof.

            (f) Each institution that maintains the Collection Account or the
Certificate Account shall invest the funds in each such account as directed by
the Servicer or the Securities Administrator, 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 Securities Administrator, as applicable, for
the benefit of the Certificateholders. All income and gain net of any losses
realized from amounts on deposit in the Collection Account shall be for the
benefit of the Servicer as servicing compensation and shall be remitted to it or
withdrawn by it monthly as provided herein. The amount of any losses incurred in
the Collection Account in respect of any such investments shall be deposited by
the Servicer in the Collection Account out of the Servicer's own funds
immediately as realized.

            (g) All income and gain net of any losses realized from amounts on
deposit in the Certificate Account shall be for the benefit of (i) the Servicer
to the extent such income and gain (net of any losses) relates to the period
from the Servicer Remittance Date to but not including the Business Day
immediately preceding the related Distribution Date and (ii) the Securities
Administrator to the extent such income and gain (net of any losses) relates to
any other period. Any amounts in such Certificate Account earned for the benefit
of the Servicer shall be remitted by the Securities Administrator to the
Servicer not later than the third Business Day of the month immediately
succeeding the month in which such amounts were earned. The amount of any losses
incurred in the Certificate Account in respect of any such investments shall be
deposited by the Servicer and/or the Securities Administrator, as applicable, in
the Certificate Account out of the Securities Administrator's own funds
immediately as realized; provided that the Securities Administrator shall be
reimbursed by the Servicer for any such losses which relate to the period from
the Servicer Remittance Date to but not including the Business Day immediately
preceding the related Distribution Date.

      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, insurance premiums,
condominium or PUD association dues, or comparable items, to reimburse the
Servicer out of related collections for any payments made pursuant to Sections
3.01 hereof (with respect to taxes, assessments, dues or comparable items and
insurance premiums) and 3.10 hereof (with respect to hazard insurance), to
refund to any Mortgagors any sums as may be determined to be overages, to pay
interest, if required by law or the terms of the related Mortgage or Mortgage
Note, to Mortgagors on balances in the Escrow Account to withdraw funds
deposited in error or amounts previously deposited but returned as unpaid due to
a "not sufficient funds" or other denial by the related Mortgagor's banking
institution or to clear and terminate the Escrow Account at the termination of
this Agreement in accordance with Section 9.01 hereof. The Escrow Accounts shall
not be a part of the Trust Fund.

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

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

      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 (the order below not constituting
an order of priority):

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

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

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

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

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

                  (vii) to pay to the Depositor or the Servicer, as applicable,
with respect to each Mortgage Loan or property acquired in respect thereof that
has been purchased pursuant to Section

                                      -78-
<PAGE>

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, the Master Servicer, the
Securities Administrator or the Depositor for expenses incurred by any of them
in connection with the Mortgage Loans or the Certificates and reimbursable
pursuant to Section 3.25 or Section 6.03 hereof;

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

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

                  (xi) to withdraw funds deposited in error or amounts
previously deposited but returned as unpaid due to a "not sufficient funds" or
other denial by the related Mortgagor's banking institution;

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

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

                  (xiv) to reimburse itself from any amounts in the Collection
Account for any prior Advances or Servicing Advances made by the Servicer that
have not otherwise been reimbursed to the Servicer at the time a Mortgage Loan
is modified.

      In addition, no later than 12:00 p.m. Eastern Time on the Servicer
Remittance Date, the Servicer shall cause to be withdrawn from the Collection
Account the Interest Funds and the Principal Funds to the extent on deposit, and
such amount shall be deposited in the Certificate Account; provided, however, if
the Securities Administrator does not receive such Interest Funds and Principal
Funds by 2:00 p.m. Eastern Time, such Interest Funds and Principal Funds shall
be deposited in the Certificate Account on the next Business Day.

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

      The Servicer shall provide written notification to the Securities
Administrator 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 Securities
Administrator for deposit into the Certificate Account any amounts (including
any Advance) required to be so remitted by the Servicer on the Servicer
Remittance Date, the Servicer shall pay to the Securities Administrator, for its
own

                                      -79-
<PAGE>

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.

      Unless otherwise specified, any amounts reimbursable to the Servicer or
the Securities Administrator 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 Securities Administrator shall withdraw funds from the
Certificate Account for distribution to the Certificateholders in the manner
specified in this Agreement (and shall withhold from the amounts so withdrawn,
the amount of any taxes that it is authorized to retain pursuant to this
Agreement). In addition, the Securities Administrator may from time to time make
withdrawals from the Certificate Account for the following purposes (the order
below not constituting an order of priority):

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

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

                  (iii) to reimburse the Securities Administrator, the Master
Servicer or the Trustee for any fees, expenses and indemnification reimbursable
pursuant to this Agreement, including without limitation Sections 3.04, 6.03,
8.05, 8.06 and 11.02 hereof; and

                  (iv) to pay to the Servicer or the Securities Administrator,
as applicable, earnings on or investment income with respect to funds in or
credited to the Certificate Account as provided in Section 3.05(g).

      Section 3.09. [RESERVED]

      Section 3.10. Maintenance of Hazard Insurance.

      The Servicer shall cause to be maintained, for each first lien 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, or (ii) the
greater of (a) the outstanding principal balance of the Mortgage Loan and (b) an
amount such that the proceeds of such policy shall be sufficient to prevent the
related Mortgagor and/or mortgagee from becoming a co-insurer or (iii) the
amount required under applicable HUD/FHA regulations. Each 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

                                      -80-
<PAGE>

to the extent and as otherwise permitted by Section 3.08 hereof. It is
understood and agreed that no earthquake or other additional insurance is to be
required of any Mortgagor or maintained on property acquired in respect of a
Mortgage other than pursuant to such applicable laws and regulations as shall at
any time be in force and as shall require such additional insurance. If the
Mortgaged Property is located at the time of origination of the Mortgage Loan in
a federally designated special flood hazard area and such area is participating
in the national flood insurance program, the Servicer shall cause flood
insurance to be maintained with respect to such first lien 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 Securities Administrator for the benefit of the
Certificateholders, claims under any such blanket policy.

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

            (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Servicer shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, but only to the extent that such enforcement will not adversely affect
or jeopardize coverage under any Required Insurance Policy; provided, however,
that the Servicer shall not exercise any such right if the due-on-sale clause,
in the reasonable belief of the Servicer, is not enforceable under applicable
law. An opinion of counsel, which shall be reimbursable as a Servicing Advance
(to the extent it is an "unanticipated expense" within the meaning of Treasury
Regulation Section 1.860G-1(b)(3)(ii)), delivered to the Securities
Administrator, Master Servicer, Trustee and the Depositor shall conclusively
establish the reasonableness of such belief to the extent permitted under
applicable law. Notwithstanding the foregoing, the Servicer is not required to
exercise such rights with respect to a Mortgage Loan if the Person to whom the
related Mortgaged Property (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

                                      -81-
<PAGE>

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 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. The Servicer
shall be responsible for recording any such assumption or substitution
agreements. 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
will increase the proceeds of liquidation of the Mortgage Loan after
reimbursement to itself of such expenses and (ii) that such expenses will be
recoverable to it through Liquidation Proceeds (respecting which it shall have
priority for purposes of withdrawals from the Collection Account pursuant to
Section 3.08 hereof). The Servicer shall be responsible for all other costs and
expenses incurred by it in any such proceedings; provided, however, that it
shall be entitled to reimbursement thereof from the proceeds of liquidation of
the related Mortgaged Property (or stock allocated to a dwelling unit, in the
case of a Co-op Loan) and if applicable, as a Non-Recoverable Servicing Advance,
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 or its affiliate may
receive usual and customary real estate referral fees for real estate brokers in
connection with the listing and disposition of REO Property. The Servicer shall
prepare a statement with respect to each REO Property that has been rented
showing the aggregate rental income received and all expenses incurred in
connection with the management and maintenance of such REO Property at such
times as is necessary to enable the Servicer to comply with the reporting
requirements of the REMIC Provisions. The net monthly rental income, if any,
from such REO Property shall be deposited in the Collection Account no later
than the close of business on 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, obtain, in accordance with applicable procedures for
obtaining an automatic extension of the grace period, 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, in which case such property must be disposed of
prior to the end of such extension, unless the Trustee and the NIMs Insurer
shall have been supplied with an Opinion of Counsel (such Opinion of Counsel not
to be an expense of the Master Servicer, Securities Administrator, 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 or extension 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 a 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 a Co-op Loan)
acquired by the Trust Fund shall be held, rented (or allowed to continue to be
rented) or otherwise used for the production of income by or on behalf of the
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 a
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 a 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
Servicer shall

                                      -83-
<PAGE>

have no liability for any losses resulting from a foreclosure on a second lien
Mortgage Loan, if any, in connection with the foreclosure of the related first
lien mortgage loan that is not a Mortgage Loan if the Servicer does not receive
notice of such foreclosure action.

      The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of such
foreclosure would exceed the costs and expenses of bringing such a proceeding.
The income earned from the management of any Mortgaged Properties acquired
through foreclosure or other judicial proceeding, net of reimbursement to the
Servicer for expenses incurred (including any property or other taxes) in
connection with such management and net of unreimbursed Servicing Fees,
Advances, Servicing Advances and any management fee paid or to be paid with
respect to the management of such Mortgaged Property (or stock allocated to a
dwelling unit, in the case of Co-op Loan), shall be applied for the purpose of
the Trust Fund 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
and as between the parties to 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.

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

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

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

            (c) The Servicer, in its sole discretion, shall have the right to
elect (by written notice sent to the Trustee, the Master Servicer and the
Securities Administrator) to purchase for its own account from the Trust Fund
any Mortgage Loan that is 90 days or more Delinquent or REO Property for which
the Servicer has accepted a deed-in-lieu of foreclosure at a price equal to the
Purchase Price. The Purchase Price for any Mortgage Loan or REO Property
purchased hereunder shall be delivered to the Securities Administrator for
deposit to the Certificate Account and the Trustee (or its custodian), upon
receipt of such confirmation of deposit and a Request for Release from the
Servicer in the form of Exhibit I hereto, shall release or cause to be released
to the Servicer the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the Servicer, in each case
without recourse, representation or warranty, as shall be necessary to vest in
the Servicer any Mortgage Loan or REO Property released pursuant hereto and the
Servicer shall succeed to all the Trustee's right, title and interest in and to
such Mortgage Loan and all security and documents related thereto. Such
assignment shall be an assignment outright and not for security. The Servicer
shall thereupon own such Mortgage Loan, and all security and documents, free of
any further obligation to the Trustee or the

                                      -84-
<PAGE>

Certificateholders with respect thereto. The Servicer shall not use any
procedure in selecting Mortgage Loans to be repurchased which is materially
adverse to the interests of the Certificateholders.

            (d) With respect to such of the Mortgage Loans as come into and
continue in default, the Servicer will decide, in its reasonable business
judgment, whether to (i) foreclose upon the Mortgaged Properties securing those
Mortgage Loans pursuant to Section 3.12(a), (ii) write off the unpaid principal
balance of the Mortgage Loans as bad debt (unless the Servicer, after making a
reasonable estimate of the expected recovery, determines that foreclosure
proceedings or other liquidation of the related Mortgaged Property would yield a
net recovery), (iii) take a deed in lieu of foreclosure, (iv) accept a short
sale or short refinance; (v) arrange for a repayment plan, or (vi) agree to a
modification of such Mortgage Loan.

            (e) Any Mortgage Loan that is charged off, pursuant to (d) above,
may continue to be serviced by the Servicer for the Certificateholders using
specialized collection procedures (including foreclosure, if appropriate). The
Servicer will be entitled to Servicing Fees and reimbursement of expenses in
connection with such Mortgage Loans after the date of charge off, only to the
extent of funds available from any recoveries on all such Mortgage Loans.

      In the event that the Servicer (or an affiliate of the Servicer) is the
owner of more than 50% of the Class of Certificates which is then currently in a
first loss position and such party is deemed to be the "Primary Beneficiary" as
defined in FIN 40, the provisions of the preceding paragraph shall not apply and
the Servicer (or an affiliate of the Servicer), in its sole discretion, shall
have the right to elect to purchase for its own account from the Trust Fund any
Mortgage Loan that is 120 days or more Delinquent or REO Property for which the
Servicer has accepted a deed-in-lieu of foreclosure, during the period
commencing on the first day of the calendar quarter succeeding the calendar
quarter in which the Initial Delinquency Date (as defined below) occurred with
respect to such Mortgage Loan and ending on the last Business Day of such
calendar quarter. If the Servicer (or an affiliate of the Servicer) does not
exercise its purchase right with respect to a Mortgage Loan during the period
specified in the preceding sentence, such Mortgage Loan shall thereafter again
become eligible for purchase pursuant to the preceding sentence only after the
Mortgage Loan ceases to be 120 days or more Delinquent and thereafter becomes
120 days Delinquent again. The "Initial Delinquency Date" of a Mortgage Loan
shall mean the date on which the Mortgage Loan first became 120 days Delinquent.
Prior to repurchase pursuant to this Section 3.12, the Servicer shall be
required to continue to make monthly advances pursuant to Section 4.01. The
Servicer shall not use any procedure in selecting Mortgage Loans to be
repurchased which is materially adverse to the interests of the
Certificateholders. The Servicer shall purchase any Mortgage Loan or REO
Property pursuant to this paragraph at a price equal to the Purchase Price. The
Purchase Price for any Mortgage Loan or REO Property purchased hereunder shall
be delivered to the Securities Administrator for deposit in the Certificate
Account. The Securities Administrator shall notify the Trustee of such deposit.
The Trustee, upon receipt of notice of such deposit and a Request for Release
from the Servicer in the form of Exhibit I hereto, shall release or cause to be
released to the Servicer the related Mortgage File and shall execute and deliver
such instruments of transfer or assignment prepared by the Servicer, in each
case without recourse, representation or warranty, as shall be necessary to vest
in the Servicer any Mortgage Loan or REO Property released pursuant hereto and
the Servicer shall succeed to all the Trustee's right, title and interest in and
to such Mortgage Loan and all security and documents related thereto. The
provisions in this paragraph shall only apply if [SERVICER] is the servicer.

      Section 3.13. Trustee to Cooperate; Release of Mortgage Files.

      Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will promptly notify the Trustee or
its designee by delivering a Request for Release substantially in the form

                                      -85-
<PAGE>

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

      Each Request for Release may be delivered to the Trustee or its designee
(i) via mail or courier, (ii) via facsimile or (iii) by such other means,
including, without limitation, electronic or computer readable medium, as the
Servicer and the Trustee or its designee shall mutually agree. The Trustee or
its designee shall promptly release the related Mortgage File(s) within five (5)
Business Days of receipt of a properly completed Request for Release pursuant to
clauses (i), (ii) or (iii) above. Receipt of a properly completed Request for
Release shall be authorization to the Trustee or its designee to release such
Mortgage Files, provided the Trustee or its designee has determined that such
Request for Release has been executed, with respect to clauses (i) or (ii)
above, or approved, with respect to clause (iii) above, by an authorized
Servicing Officer of the Servicer, and so long as the Trustee or its designee
complies with its duties and obligations under the agreement. If the Trustee or
its designee is unable to release the Mortgage Files within the period
previously specified, the Trustee or its designee shall immediately notify the
Servicer indicating the reason for such delay. If the Servicer is required to
pay penalties or damages due to the Trustee or its designee's negligent failure
to release the related Mortgage File or the Trustee or its designee's negligent
failure to execute and release documents in a timely manner, the Trustee or its
designee, shall be liable for such penalties or damages respectively caused by
it.

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

      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 a Co-op Loan) as authorized by this Agreement, the Servicer may deliver
or cause to be delivered to the Trustee or its designee, for signature, as
appropriate or on behalf of the Trustee, execute any court pleadings, requests
for trustee's sale or other documents necessary to effectuate such foreclosure
or any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity. Notwithstanding the foregoing, the
Servicer shall cause possession of any Mortgage File or of the documents therein
that shall have been released by the Trustee 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)

                                      -86-
<PAGE>

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 a 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 Trust Fund, subject to the applicable provisions
of this Agreement. The Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Collection
Account or Certificate Account or in any Escrow Account, or any funds that
otherwise are or may become due or payable to the Trustee or the Securities
Administrator for the benefit of the Certificateholders, to any claim, lien,
security interest, judgment, levy, writ of attachment or other encumbrance, or
assert by legal action or otherwise any claim or right of set off against any
Mortgage File or any funds collected on, or in connection with, a Mortgage Loan,
except, however, that the Servicer shall be entitled to set off against and
deduct from any such funds any amounts that are properly due and payable to the
Servicer under this Agreement.

      Section 3.15. Servicing Compensation.

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

      Additional servicing compensation in the form of any Excess Proceeds, late
payment fees, assumption fees (i.e. fees related to the assumption of a Mortgage
Loan upon the purchase of the related Mortgaged Property (or stock allocated to
a dwelling unit, in the case of Co-op Loan)), modification fees, customary real
estate referral fees, extension fees and similar fees payable by the Mortgagor,
Prepayment Interest Excess, 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. In addition, the Servicer shall be
entitled to income and gain from amounts on deposit in the Certificate Account
during the period from the Servicer Remittance date to but not including the
Business Day immediately preceding the related Distribution Date as described in
Section 3.05(g). The Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder (including payment of
any premiums for hazard insurance, as required by Section 3.10 hereof and
maintenance of the other forms of insurance coverage required by Section 3.10
hereof) and shall not be entitled to reimbursement therefor except as
specifically provided in this Agreement. In no event shall the Trustee or the
Securities Administrator be liable for any Servicing Fee or for any differential
between the Servicing Fee and the amount necessary to induce a successor
servicer to act as successor servicer under this Agreement.

      Section 3.16. Access to Certain Documentation.

      The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of the Certificates and the examiners
and supervisory agents of the OTS, the FDIC and such other authorities, 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.

      (a) The Servicer will deliver to the Master Servicer and the Trustee on or
before March 31 of each year beginning in 20__ or such other date in order to

      Section 3.26. Nonsolicitation.

      For as long as the Servicer services the Mortgage Loans, the Servicer
covenants that it will not, and that it will ensure that its affiliates and
agents will not, directly solicit or provide information for any other party to
solicit for prepayment or refinancing of any of the Mortgage Loans by the
related Mortgagors. Neither the Servicer nor any affiliate of the Servicer shall
be deemed to directly solicit any Mortgagor if the Servicer, or its affiliate,
responds to a request from a Mortgagor regarding a refinancing or if the
Mortgagor receives marketing materials that are generally disseminated. 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 IV

                                  DISTRIBUTIONS

      Section 4.01. Advances.

            (a) Subject to the conditions of this Article IV, the Servicer, as
required below, shall make an Advance and deposit such Advance in the Collection
Account. 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 Securities
Administrator for the benefit of the Certificateholders, funds constituting the
remaining portion of such Advance, if applicable, and (ii) to the Depositor, the
NIMs Insurer and the Master Servicer an Officer's Certificate setting forth the
basis for such determination. The Servicer may, in its sole discretion, make an
Advance with respect to the principal portion of the final Scheduled Payment on
a Balloon Loan, but the Servicer is under no obligation to do so; provided,
however, that nothing in this sentence shall affect the Servicer's obligation
under this Section 4.01 to advance the interest portion of the final Scheduled
Payment with respect to a Balloon Loan as if such Balloon Loan were a fully
amortizing Mortgage Loan. If a Mortgagor does not pay its final Scheduled
Payment on a Balloon Loan when due, the Servicer shall Advance (unless it
determines in its good faith judgment that such amounts would constitute a
Non-Recoverable Advance) a full month of interest (net of the Servicing Fee) on
the Stated Principal Balance thereof each month until its Stated Principal
Balance is reduced to zero.

      In lieu of making all or a portion of such Advance from its own funds, the
Servicer may (i) cause to be made an appropriate entry in its records relating
to the Collection Account that any amount held for future distribution has been
used by the Servicer in discharge of its obligation to make any such Advance and
(ii) transfer such funds from the Collection Account to the Certificate Account.
In addition, the Servicer shall have the right to reimburse itself for any such
Advance from amounts held from time to time in the Collection Account to the
extent such amounts are not then required to be distributed. Any

                                      -92-
<PAGE>

funds so applied and transferred pursuant to the previous two sentences shall be
replaced by the Servicer by deposit in the Collection Account no later than the
close of business on the Servicer Advance Date on which such funds are required
to be distributed pursuant to this Agreement. The Servicer shall be entitled to
be reimbursed from the Collection Account for all Advances of its own funds made
pursuant to this Section as provided in Section 3.08. The obligation to make
Advances with respect to any Mortgage Loan shall continue until the earlier of
(i) the date such Mortgage Loan is paid in full, (ii) the date the related
Mortgaged Property (or stock allocated to a dwelling unit, in the case of a
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, or (iii) the date on which such Mortgage Loan becomes 150 days
delinquent as set forth below.

            (b) Notwithstanding anything in this Agreement to the contrary
(including, but not limited to, Sections 3.01 and 4.01(a) hereof), no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer if such
Advance or Servicing Advance would, if made, constitute a Non-Recoverable
Advance or a Non-Recoverable Servicing Advance. The determination by the
Servicer that it has made a Non-Recoverable Advance or a Non-Recoverable
Servicing Advance or that any proposed Advance or Servicing Advance, if made,
would constitute a Non-Recoverable Advance or a Non-Recoverable Servicing
Advance, respectively, shall be evidenced by an Officer's Certificate of the
Servicer delivered to the Depositor and the Master Servicer. In addition, the
Servicer shall not be required to advance any Relief Act Shortfalls. The
Servicer will not make any Advances of principal on REO Properties and is
required to advance only the interest portion on second lien mortgage loans.

            (c) Notwithstanding the foregoing, the Servicer shall not be
required to make any Advances for any Mortgage Loan after such Mortgage Loan
becomes 150 days delinquent.

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

      In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall resulting from a Principal Prepayment in full, the Servicer
shall, from amounts in respect of the Servicing Fee for such Distribution Date,
deposit into the Collection Account, as a reduction of the Servicing Fee for
such Distribution Date, no later than the Servicer Advance Date immediately
preceding such Distribution Date, an amount up to the Prepayment Interest
Shortfall; provided that the amount so deposited with respect to any
Distribution Date shall be limited to one half of the product of (x) one-twelfth
of 0.50% and (y) the aggregate Stated Principal Balance of the Mortgage Loans.
In case of such deposit, the Servicer shall not be entitled to any recovery or
reimbursement from the Depositor, the Master Servicer, the Securities
Administrator, the Trustee, the Trust Fund or the Certificateholders. With
respect to any Distribution Date, to the extent that the Prepayment Interest
Shortfall exceeds Compensating Interest (such excess, a "Non-Supported Interest
Shortfall"), such Non-Supported Interest Shortfall shall reduce the Current
Interest with respect to each Class of Certificates, pro rata, based upon the
amount of interest each such Class would otherwise be entitled to receive on
such Distribution Date. Notwithstanding the foregoing, there shall be no
reduction of the Servicing Fee in connection with Prepayment Interest Shortfalls
relating to the Relief Act and the Servicer shall not be obligated to pay
Compensating Interest with respect to Prepayment Interest Shortfalls related to
the Relief Act.

      Section 4.03. Distributions on the REMIC Interests.

      On each Distribution Date, amounts on deposit in the Certificate Account
shall be treated for federal income tax purposes as applied to distributions on
the interests in the Lower Tier REMIC in an

                                      -93-
<PAGE>

amount sufficient to make the distributions on the respective Certificates on
such Distribution Date in accordance with the provisions of Section 4.04.

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

Current Interest for each such class and any Interest Carry Forward Amount with
respect to each such class;

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

            (d) On each Distribution Date, the Securities Administrator shall
make the following distributions from the Certificate Account of an amount equal

            (j) Subject to Section 9.02 hereof respecting the final

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 Securities Administrator 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 (the "Remittance Report") to the Securities Administrator in the form
of a computer readable magnetic tape (or by such other means as the Servicer and
the Securities Administrator may agree from time to time)

                                      -98-
<PAGE>
containing such data and information as to permit the Securities Administrator
to prepare the Monthly Statement to Certificateholders and make the required
distributions for the related Distribution Date. The Securities Administrator
will prepare the Monthly Report based solely upon the information received from
the Servicer.

      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) The Securities Administrator is hereby directed by the Depositor
to execute the Cap Contracts on behalf of the Trust Fund in the form presented
to it by the Depositor and shall have no responsibility for the contents of such
Cap Contract, including, without limitation, the representations and warranties
contained therein. Any funds payable by the Securities Administrator under the
Cap Contracts at closing shall be paid by the Depositor. Notwithstanding
anything to the contrary contained herein or in any Cap Contract, except as set
forth in Section 11 of each Cap Contract, the Securities Administrator shall not
be required to make any payments to the counterparty under any Cap Contract. Any
payments received under the terms of the related Cap Contract will be available
to pay the holders of the related Class A, Class M and Class B Certificates up
to the amount of any Floating Rate Certificate Carryovers remaining after all
other distributions required under this Section 4.04 are made on such
Distribution Date, other than Floating Rate Certificate Carryovers attributable
to the fact that Applied Realized Loss Amounts are not allocated to the Class A
Certificates. Any amounts received under the terms of any Cap Contract on a
Distribution Date that are not used to pay such Floating Rate Certificate
Carryovers will be distributed to the holders of the Class C Certificates.
Payments in respect of such Floating Rate Certificate Carryovers from proceeds
of a Cap Contract shall be paid to the related Classes of Class A, Class M and
Class B Certificates, pro rata based upon such Floating Rate Certificate
Carryovers for each such class of Class A, Class M and Class B Certificates.
Amounts received on the Class A-1 Cap Contract will only be available to make
payments on the Class A-1 and Class R certificates, amounts received on the
Class A-2 Cap Contract will only be available to make payments on the Class
A-2A1, Class A-2A2 and Class A-2B certificates, amounts received on the Class
A-3/Class M Cap Contract will only be available to make payments on the Class
A-3 and Class M Certificates and amounts received on the Class B Cap Contract
will only be available to make payments on the Class B-1A, Class B-2A, Class
B-3A and Class B-4A certificates.

                  (i) The Securities Administrator shall establish and maintain,
for the benefit of the Trust Fund and the Certificateholders, the Cap Contract
Account. On or prior to the related Cap Contract Termination Date, amounts, if
any, received by the Securities Administrator for the benefit of the Trust Fund
in respect of the related Cap Contract shall be deposited by the Securities
Administrator

                                      -99-
<PAGE>

into the Cap Contract Account and will be used to pay Floating Rate Certificate
Carryovers on the related Class A, Class M and Class B Certificates to the
extent provided in the immediately preceding paragraph. With respect to any
Distribution Date on or prior to the related Cap Contract Termination Date, the
amount, if any, payable by the Cap Contract Counterparty under the related 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 the
rate with respect to such Distribution Date as shown under the heading "1ML
Upper Collar" in the schedule to the related Cap Contract), over (y) the rate
with respect to such Distribution Date as shown under the heading "1ML Strike
Lower Collar" in the schedule to the related Cap Contract, (ii) an amount equal
to the lesser of (x) the related Cap Contract Notional Balance for such
Distribution Date and (y) the outstanding Certificate Principal Balance of the
related classes of Certificates and (iii) the number of days in such Accrual
Period, divided by 360. If a payment is made to the Trust Fund under a Cap
Contract and the Securities Administrator is required to distribute excess
amounts to the holders of the Class C Certificates as described above,
information regarding such distribution will be included in the monthly
statement made available on the Securities Administrator's website pursuant to
Section 4.05 hereof.

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

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

(1)   The Class C Certificates shall not have minimum dollar denominations or
      certificate notional amounts and shall be issued in a minimum percentage
      interest of [10]%. The initial Overcollateralization Amount is $________.

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

      The Certificates shall be executed by manual or facsimile signature on
behalf of the Securities Administrator 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
Securities Administrator 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 Securities Administrator 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,

                                      -104-

the Securities Administrator shall authenticate the Certificates to be issued at
the written direction of the Depositor, or any Affiliate thereof.

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

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

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

            (a) The Securities Administrator 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 Securities Administrator 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 Securities
Administrator shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates of the same Class and of
like aggregate Percentage Interest.

      At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Securities Administrator. Whenever any
Certificates are so surrendered for exchange, the Securities Administrator shall
execute, authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Securities
Administrator 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 Securities Administrator in accordance
with such Securities Administrator's customary procedures.

                                     -105-
<PAGE>

            (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 the Securities Administrator in writing the facts surrounding
the Transfer in substantially the form set forth in Exhibit F (the "Transferor
Certificate") and (i) deliver a letter in substantially the form of either
Exhibit G (the "Investment Letter") or Exhibit H (the "Rule 144A Letter") or
(ii) there shall be delivered to the Securities Administrator 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, the Securities Administrator 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
Securities Administrator 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 Securities
Administrator 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, the Securities Administrator and the Trustee against
any liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

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

      No transfer of an ERISA Restricted Certificate or a Class R Certificate
will be registered unless the Securities Administrator has received (A) a
representation that such transferee is not an employee benefit plan subject to
Title I of ERISA, a plan subject to Section 4975 of the Code or a plan subject
to any state, local, federal, non-U.S. or other law substantively similar to the
foregoing provisions of ERISA

                                     -106-
<PAGE>

or the Code ("Similar Law") (collectively, a "Plan"), and is not directly or
indirectly acquiring such Certificate for, on behalf of, or with any assets of
any such Plan, (B) solely in the case of an ERISA Restricted Certificate (I) if
the Certificate has been the subject of an ERISA-Qualifying Underwriting, a
representation that such transferee is an insurance company that is acquiring
the Certificate with assets contained in an "insurance company general account,"
as defined in Section V(e) of Prohibited Transaction Class Exemption ("PTCE")
95-60, and the acquisition and holding of the Certificate are covered and exempt
under Sections I and III of PTCE 95-60, or (II) solely in the case of an ERISA
Restricted Certificate that is a Definitive Certificate, an Opinion of Counsel
satisfactory to the Securities Administrator, and upon which the Securities
Administrator and the NIMs Insurer shall be entitled to rely, to the effect that
the acquisition and holding of such Certificate will not constitute or result in
a nonexempt prohibited transaction under Title I of ERISA or Section 4975 of the
Code, or a violation of Similar Law, and will not subject the Trustee, the
Master Servicer, the Securities Administrator, the Servicer, the NIMs Insurer or
the Depositor to any obligation in addition to those expressly undertaken in
this Agreement, which Opinion of Counsel shall not be an expense of the
Securities Administrator, the Trustee, the Master Servicer, the Servicer, the
NIMs Insurer or the Depositor.

Except in the case of a Definitive Certificate, the representations as set forth
in the immediately preceding paragraph, other than clause (B)(II) in the
immediately preceding paragraph, shall be deemed to have been made to the
Securities Administrator by the transferee's acceptance of an ERISA Restricted
Certificate or a Class R Certificate (or the acceptance by a Certificate Owner
of the beneficial interest in any Class of ERISA Restricted Certificates or a
Class R Certificate).

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

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

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

                  (ii) No Ownership Interest in a Class R Certificate may be
purchased, transferred or sold, directly or indirectly, except in accordance
with the provisions hereof. No Ownership Interest in a Class R Certificate may
be registered on the Closing Date or thereafter transferred, and the Securities
Administrator shall not register the Transfer of any Class R Certificate unless,
in addition to the certificates required to be delivered to the Securities
Administrator under subparagraph (b) above, the

                                     -107-
<PAGE>

Securities Administrator shall have been furnished with an affidavit (a
"Transfer Affidavit") of the initial owner or the proposed transferee in the
form attached hereto as Exhibit E-1 and an affidavit of the proposed transferor
in the form attached hereto as Exhibit E-2. In the absence of a contrary
instruction from the transferor of a Class R Certificate, declaration (11) in
Appendix A of the Transfer Affidavit may be left blank. If the transferor
requests by written notice to the Securities Administrator 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 Securities Administrator
with a duly completed and effective Internal Revenue Service Form W-8ECI (or any
successor thereto) and the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator shall be paid and delivered by the Securities
Administrator 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 and the residual interest in the Upper Tier REMIC may be
severed and represented by separate certificates (with the certificate that
represents the Residual Interest also representing all rights of the Class R
Certificate to distributions attributable to a Pass-Through Rate on the Class R
Certificate in excess of the REMIC Pass-Through Rate); provided, however, that
such separate certification may not occur until the Securities Administrator and
the NIMs Insurer 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 and the residual interest in the Upper Tier REMIC shall be severed
and represented by separate Certificates.

                                     -108-
<PAGE>

                  (vi) [RESERVED]

      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 Securities Administrator and the NIMs Insurer of an
Opinion of Counsel, which Opinion of Counsel shall not be an expense of the
Securities Administrator, the NIMs Insurer 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 Securities Administrator, 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
Securities Administrator in writing upon the transfer of the Class R
Certificate.

            (e) The Privately Offered Certificates may not be offered or sold
except to (i) QIBs in reliance on the exemption from the registration
requirements of the Securities Act provided by Rule 144A that are "United States
Persons" for purposes of the Code, (ii) Institutional Accredited Investors, that
are United States Persons (as defined by Regulation S) for purposes of the Code
or (iii) outside the United States, persons who are not U.S. persons (as defined
by Regulation S) in offshore transactions in compliance with Regulation S.

      To permit compliance with the foregoing in connection with any proposed
transfer of the Privately Offered Certificates, the Securities Administrator
shall cooperate with the Depositor in furnishing, upon the request of any
Certificateholder, to such Certificateholder or Certificate Owner and a
prospective transferee designated by such Certificateholder, the information
required to be delivered under Rule 144A(d)(4).

      Each Certificateholder, by its acceptance of a Privately Offered
Certificate, will be deemed to have represented and agreed as follows (terms
used in this section that are defined in Rule 144A are used herein as defined
therein):

            (1) It (A)(i) is a QIB, (ii) is aware that the sale of the Class
      B-1A, Class B-1B, Class B-2A, Class B-2B, Class B-3A, Class B-3B, Class
      B-4A, Class B-4B or Class M-6 Certificates, as applicable, is being made
      in reliance on Rule 144A and (iii) is acquiring such Certificates for its
      own account or for the account of a QIB, as the case may be, (B)(i) is an
      Institutional Accredited Investor, (ii) is purchasing the Class B-1A,
      Class B-1B, Class B-2A, Class B-2B, Class B-3A, Class B-3B, Class B-4A,
      Class B-4B, or Class M-6 Certificates being sold to it for its own account
      or for certain qualified institutional accounts and (iii) is not acquiring
      such Class B-1A, Class B-1B, Class B-2A, Class B-2B, Class B-3A, Class
      B-3B, Class B-4A, Class B-4B, or Class M-6 Certificates with a view to any
      resale or distribution thereof other than in accordance with the
      restrictions set forth below or (C) (i) is not a U.S. person (as defined
      by Regulation S), (ii) was at the time the buy order was originated
      outside the United States and (iii) until the expiration of the 40-day
      distribution compliance period (within the meaning of Regulation S), no
      offer, sale, pledge or other transfer of such Certificates or any interest

                                     -109-

      benefit of a U.S. person (as defined by Regulation S).

      been and will not be registered under the Securities Act and may not be
      reoffered, resold, pledged or otherwise transferred except (A)(i) to a
      Person whom it reasonably believes is a QIB in a transaction meeting the
      requirements of Rule 144A, (ii) to an Institutional Accredited Investor in
      a transaction exempt from the registration requirements of the Securities
      Act, or (iii) outside the United States, to Persons who are not U.S.
      persons (as defined by Regulation S) in offshore transactions in
      compliance with Regulation S and (B) in accordance with all applicable
      securities laws of the states of the United States.

            (3) It understands that any Privately Offered Certificates acquired
      by it pursuant to clause (1)(B) above will be in the form of definitive
      physical certificates ("Certificates") bearing the legend set forth in
      paragraph (4) below.

            (4) The Privately Offered Certificates will bear a legend to the
      following effect:

            1933, AS AMENDED (THE "ACT"), THE INVESTMENT COMPANY ACT OF 1940, AS

            SUBJECT TO REGISTRATION UNDER THE ACT, THE 1940 ACT AND ANY
            APPLICABLE STATE SECURITIES LAWS AND SUCH TRANSFER ALSO COMPLIES
            WITH THE OTHER PROVISIONS OF SECTION 5.02 OF THE POOLING AND
            SERVICING AGREEMENT. IF THE CERTIFICATE IS A DEFINITIVE CERTIFICATE,
            NO TRANSFER OF THIS CERTIFICATE SHALL BE MADE UNLESS THE SECURITIES
            ADMINISTRATOR SHALL HAVE RECEIVED, IN FORM AND SUBSTANCE
            SATISFACTORY TO THE SECURITIES ADMINISTRATOR (A) AN INVESTMENT
            LETTER FROM THE PROSPECTIVE INVESTOR; AND (B) REPRESENTATIONS FROM

                  (5) Any information the purchaser desires concerning the
            Privately Offered Certificates or any other matter relevant to its
            decision to purchase the Privately Offered Certificates is or has
            been made available to it.

      The transferor of a Privately Offered Certificate or a beneficial interest
in a Privately Offered Certificate (except in the case of the transfer of (i) a
beneficial interest in a Rule 144A Book-Entry Certificate for a beneficial
interest in a Rule 144A Book-Entry Certificate or (ii) a beneficial interest in
a Regulation S Book-Entry Certificate for a beneficial interest in a Regulation
S Book-Entry Certificate) shall be required to provide to the Securities
Administrator (i) in the case of a transferor holding a Definitive Certificate
or a beneficial interest in a Regulation S Book-Entry Certificate and wishing to
transfer to a Person in the form of a beneficial interest in a Rule 144A
Book-Entry Certificate, a transferor letter substantially in the form attached
as Exhibit H and a transferee letter substantially in the form attached as
Exhibit H or (ii) in the case of a transferor holding a Definitive Certificate
or a beneficial interest in a Rule 144A Book-Entry Certificate and wishing to

      The Securities Administrator may conclusively rely on any such transferor
letter and representation letter as sufficient to confirm that the proposed
transfer is being made pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act and other
applicable laws.

            (f) 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, the Securities Administrator or the Trustee.

      SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

      If (a) any mutilated Certificate is surrendered to the Securities
Administrator or the Securities Administrator 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 Securities Administrator and
the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Securities Administrator
that such Certificate has been acquired by a bona fide purchaser, the Securities
Administrator 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 Securities
Administrator 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 Securities Administrator and
the Trustee and their counsel) connected therewith. Any replacement Certificate
issued pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate

                                     -112-
<PAGE>

shall be found at any time. All Certificates surrendered to the Securities
Administrator under the terms of this Section 5.03 shall be canceled and
destroyed by the Securities Administrator in accordance with its standard
procedures without liability on its part.

      SECTION 5.04. Persons Deemed Owners.

      The NIMs Insurer, the Trustee, the Securities Administrator and any agent
of the NIMs Insurer, the Trustee or the Securities Administrator may treat the
Person in whose name any Certificate is registered as the owner of such

Agreement and for all other purposes whatsoever, and none of the NIMs Insurer,
the Trustee or the Securities Administrator, nor any agent of the NIMs Insurer,
the Trustee or the Securities Administrator 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 Securities Administrator, (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 Securities Administrator, then the Securities Administrator
shall, within ten Business Days after the receipt of such request, provide the
NIMs Insurer or the Depositor or such Certificateholders at such recipients'
expense the most recent list of the Certificateholders of the Trust Fund held by
the Securities Administrator, if any. The Depositor and every Certificateholder,
by receiving and holding a Certificate, agree that the Securities Administrator
shall not be held accountable by reason of the disclosure of any such
information as to the list of the Certificateholders hereunder, regardless of
the source from which such information was derived.

      SECTION 5.06. Book-Entry Certificates.

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

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 Securities Administrator, the NIMs Insurer
and the Trustee may deal with the Depository and the Depository Participants for

representative of the respective Certificate Owners of the Book-Entry
Certificates;

            (c) registration of the Book-Entry Certificates may not be
transferred by the Securities Administrator 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

                                     -113-
<PAGE>

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

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

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

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

      SECTION 5.07. Notices to Depository.

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

      SECTION 5.08. Definitive Certificates.

      (a) If, after Book-Entry Certificates have been issued with respect to any
Certificates, (i) the Depository or the Depositor advises the Securities
Administrator and 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 Securities
Administrator or the Depositor is unable to locate a qualified successor, (ii)
the Depositor notifies the Securities Administrator of its intent to terminate
the book-entry system through the Depository and, upon receipt of notice of such
intent from the Depository, the Certificate Owners of the Book-Entry
Certificates agree to initiate such termination or (iii) 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 Securities Administrator, 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 Securities
Administrator 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
Securities Administrator with an adequate inventory of certificates to
facilitate the issuance and transfer of Definitive Certificates. Upon surrender
to the Securities Administrator of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for

                                     -114-
<PAGE>

registration, the Securities Administrator shall authenticate and deliver such
Definitive Certificates. Neither the Depositor nor the Securities Administrator
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 Securities Administrator, to the extent
applicable with respect to such Definitive Certificates and the Securities
Administrator shall recognize the Holders of such Definitive Certificates as
Certificateholders hereunder.

      (b) Any Privately Offered Certificate sold to an "accredited investor" (as
defined under Rule 501(a)(1), (2), (3) or (7) under the Securities Act) shall be
issued in the form of one or more Definitive Certificates. The Securities
Administrator will effect such transfer in accordance with its customary
procedures.

      SECTION 5.09. Maintenance of Office or Agency.

      The Securities Administrator 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 Securities
Administrator initially designates its offices at ___________________as offices
for such purposes. The Securities Administrator will give prompt written notice
to the Certificateholders of any change in such location of any such office or
agency.

                                  ADMINISTRATOR

      SECTION 6.01. Respective Liabilities of the Depositor, the Master
Servicer, the Servicer and the Securities Administrator.

      The Depositor, the Master Servicer, the Servicer and the Securities
Administrator shall each be liable in accordance herewith only to the extent of

them herein.

      SECTION 6.02. Merger or Consolidation of the Depositor, the Master
Servicer, the Servicer or the Securities Administrator.

      Except as provided in the next paragraph, the Depositor, the Master
Servicer, the Servicer and the Securities Administrator will each keep in full
effect its existence, rights and franchises as a corporation, a limited
liability company, a limited partnership 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, the Master Servicer, the Servicer or
the Securities Administrator may be merged or consolidated, or any Person
resulting from any merger or consolidation to which the Depositor, the Master
Servicer, the Servicer or the Securities Administrator shall be a party, or any
Person succeeding to the business of the Depositor, the Master Servicer, the
Servicer or the Securities Administrator, shall be the successor of the
Depositor, the Master Servicer, the Securities Administrator or the Servicer, as
the case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding

                                     -115-

and to service mortgage loans on behalf of, Fannie Mae or Freddie Mac.

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

      None of the Depositor, the Master Servicer, the Servicer, the Securities

this provision shall not protect the Depositor, the Master Servicer, the
Servicer, the Securities Administrator or any such Person against any breach of
representations or warranties made by it herein or protect the Depositor, the
Master Servicer, the Servicer, the Securities Administrator or any such Person
from any liability that would otherwise be imposed by reasons of willful

Servicer nor the Securities Administrator 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, the Master
Servicer, the Servicer or the Securities Administrator in its discretion may
undertake any such action that it may deem necessary or desirable in respect of
this Agreement and the rights and duties of the parties hereto and the interests
of the Trustee and the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall be

breach or default by any party hereto, the reasonable compensation, expenses and
disbursements of such persons), except any such compensation, expense,
disbursement or advance that

                                     -116-
<PAGE>

either (i) arises from its negligence, bad faith or willful misconduct or (ii)
does not constitute an "unanticipated expense" within the meaning of Treasury
Regulations Section 1.860G-1(b)(3)(ii).

      SECTION 6.04. Limitation on Resignation of Servicer.

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

      Notwithstanding anything to the contrary in the previous paragraph of this
Section 6.04, the Trustee, the Securities Administrator, the Master Servicer,
the Depositor and the NIMs Insurer hereby specifically (i) consent to the pledge
and assignment by the Servicer of all the Servicer's right, title and interest
in, to and under this Agreement to the Servicing Rights Pledgee, if any, for the
benefit of certain lenders, and (ii) agree that upon delivery to the Trustee by
the Servicing Rights Pledgee of a letter signed by the Servicer whereby the
Servicer shall resign as Servicer under this Agreement, notwithstanding anything
to the contrary which may be set forth in Section 3.04 above, the Trustee shall
appoint the Servicing Rights Pledgee or its designee as successor servicer,
provided that the Servicer's resignation will not be effective unless, at the
time of such appointment, the Servicing Rights Pledgee or its designee (i) meets
the requirements of a successor servicer under Section 7.03 of this Agreement
(including being acceptable to the Rating Agencies), provided, that the consent
and approval of the Trustee, the Securities Administrator, the Master Servicer,
the Depositor and the NIMS Insurer shall be deemed to have been given to the
Servicing Rights Pledgee or its designee, and the Servicing Rights Pledgee and
its designee are hereby agreed to be acceptable to the Trustee, the Securities
Administrator, the Master Servicer, the Depositor and the NIMS Insurer and (ii)
agrees to be subject to the terms of this Agreement. If, pursuant to any
provision hereof, the duties of the Servicer are transferred to a successor
servicer, the entire amount of the Servicing Fee and other compensation payable
to the Servicer pursuant hereto shall thereafter be payable to such successor
servicer.

      SECTION 6.05. Errors and Omissions Insurance; Fidelity Bonds.

      The Servicer shall, for so long as it acts as servicer under this
Agreement, obtain and maintain in force (a) a policy or policies of insurance
covering errors and omissions in the performance of its obligations as servicer
hereunder, and (b) a fidelity bond in respect of its officers, employees and
agents. Each such policy or policies and bond shall, together, comply with the
requirements from time to time of Fannie Mae or Freddie Mac for Persons
performing servicing for mortgage loans purchased by Fannie Mae or Freddie Mac
unless the Servicer has obtained a waiver of such requirements from the Seller.
The Servicer shall provide the Trustee, the NIMs Insurer and the Master
Servicer, upon request and reasonable notice, with copies of such policies and
fidelity bond or a certification from the insurance provider evidencing such
policies and fidelity bond. The Servicer may be deemed to have complied with
this provision if an Affiliate of the Servicer has such errors and omissions and
fidelity bond coverage and, by the terms of such insurance policy or fidelity
bond, the coverage afforded thereunder extends to the Servicer. In the event
that any such policy or bond ceases to be in effect, the Servicer shall use its
reasonable best efforts to obtain a comparable replacement policy or bond from
an insurer or issuer meeting the requirements set forth above as of the date of
such replacement. Each year, together with the

                                     -117-
<PAGE>

Annual Statement as to Compliance delivered pursuant to Section 3.17, the
Servicer shall cause to be delivered to the Trustee proof of coverage of the
fidelity bond and errors and omissions insurance policy and a statement from the
surety and the insurer that the surety and the insurer shall endeavor to notify
the Trustee within thirty (30) days prior to such fidelity bond's errors and
omissions insurance policy's termination or material modification.

      SECTION 6.06. Limitation on Resignation of the Master Servicer.

      The Master 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 pursuant to the
preceding sentence permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect obtained at the expense of the
Master Servicer and delivered to the Trustee and the Rating Agencies. No
resignation of the Master Servicer shall become effective until the Trustee or
another successor Master Servicer shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement. If the Master Servicer and the Securities Administrator are the same
Person, then at any time the Master Servicer is terminated hereunder, the
Securities Administrator shall likewise be removed as securities administrator
hereunder.

      SECTION 6.07. Assignment of Master Servicing.

      The Master Servicer may sell and assign its rights and delegate its duties
and obligations in their entirety as Master Servicer under this Agreement;
provided, however, that: (i) the purchaser or transferee accept in writing such
assignment and delegation and assume the obligations of the Master Servicer
hereunder and shall (a) be a Person which shall be qualified to service mortgage
loans for Fannie Mae or Freddie Mac; (b) have a net worth of not less than
$15,000,000 (unless otherwise approved by each Rating Agency pursuant to clause

and (d) execute and deliver to the Trustee an agreement, in form and substance
reasonably satisfactory to the Trustee and which contains an assumption by such
Person of the due and punctual performance and observance of each covenant and
condition to be performed or observed by it as master servicer under this
Agreement, any custodial agreement from and after the effective date of such
agreement; (ii) each Rating Agency shall be given prior written notice of the
identity of the proposed successor to the Master Servicer and each Rating
Agency's rating of the Certificates in effect immediately prior to such
assignment, sale and delegation will not be downgraded, qualified or withdrawn
as a result of such assignment, sale and delegation, as evidenced by a letter to
such effect delivered to the Master Servicer and the Trustee; and (iii) the
Master Servicer assigning and selling the master servicing shall deliver to the
Trustee an Officer's Certificate and an independent Opinion of Counsel, each
stating that all conditions precedent to such action under this Agreement have
been completed and such action is permitted by and complies with the terms of
this Agreement. No such assignment or delegation shall affect any liability of
the Master Servicer arising out of acts or omissions prior to the effective date
thereof.

Securities Administrator 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 Securities Administrator or the Depositor, or
to the Securities Administrator 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

                  (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 Master Servicer, the Securities
Administrator, the Trustee or the Depositor, or to the Master Servicer, the
Securities Administrator, the Trustee and the Depositor 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 or

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

      If an Event of Default shall occur with respect to the Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, or solely with respect to
clause (i) above by 5:00 p.m. on the Servicer Remittance Date, the Master
Servicer may, 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 and the Servicing
Rights Pledgee, if any (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
Master Servicer. To the extent the Event of Default resulted from the failure of
the Servicer to make a required Advance, the Master Servicer shall thereupon
make any Advance described

                                     -119-
<PAGE>

in Section 4.01 hereof subject to Section 3.04 hereof. The Master Servicer 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
Master Servicer in effecting the termination of the Servicer's responsibilities
and rights hereunder, including, without limitation, the transfer to the Master
Servicer of all cash amounts which shall at the time be credited to the
Collection Account, or thereafter be received with respect to the Mortgage
Loans. The Servicer and the Master Servicer shall promptly notify the Rating
Agencies of the occurrence of an Event of Default or an event that, with notice,
passage of time, other action or any combination of the foregoing would be an
Event of Default, such notice to be provided in any event within two Business
Days of such occurrence.

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

      SECTION 7.02. Servicer Trigger Event.

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

</TABLE>

      Upon discovery by the Securities Administrator that a Servicer Trigger
Event has occurred, the Securities Administrator shall promptly (and in any
event within 5 Business Days of discovery) give written notice thereof to the
Certificateholders. If a Servicer Trigger Event shall occur, then the Holders of
Certificates evidencing not less than 51% of the Voting Rights evidenced by the
Certificates (with the

                                     -120-
<PAGE>
written consent of the NIMs Insurer, except after a NIMs Insurer Default), may,
by notice in writing to the Servicer (with a copy to each Rating Agency),
terminate all of the rights and obligations of the Servicer under this Agreement
and in and to the Mortgage Loans and the proceeds thereof, other than its rights
as a Certificateholder hereunder. On or after the receipt by the Servicer of
such written notice, all authority and power of the Servicer hereunder, subject
to and in accordance with Section 6.04 hereof, whether with respect to the
Mortgage Loans or otherwise, shall pass to and be vested in the Master Servicer
as successor servicer. The Master Servicer is hereby authorized and empowered as
successor servicer to execute and deliver, on behalf of the Servicer, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such termination
shall affect any obligation of the Servicer to pay amounts owed pursuant to
Article VIII. The Servicer agrees to cooperate with the Master Servicer as
successor servicer in effecting the termination of the Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer to the Master Servicer as successor servicer of all cash amounts which
shall at the time be credited to the Collection Account, or thereafter be
received with respect to the Mortgage Loans. The Servicer and the Master
Servicer shall promptly notify the Rating Agencies of the occurrence of a
Servicer Trigger Event, such notice to be provided in any event within two
Business Days of such occurrence.

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

      SECTION 7.03. Master Servicer to Act; Appointment of Successor.

      On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 hereof, the Master Servicer 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 Master Servicer shall be entitled to all fees, compensation and
reimbursement for costs and expenses relating to the Mortgage Loans that the
Servicer would have been entitled to hereunder if the Servicer had continued to
act hereunder. Notwithstanding the foregoing, if the Master Servicer has become
the successor to the Servicer in accordance with Section 7.01 hereof, the Master
Servicer 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, the
Trustee and the Master Servicer an agreement accepting such delegation and
assignment, that contains an assumption by such Person of the

                                     -121-
<PAGE>
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 Master Servicer
shall have consented thereto, prior written consent of the NIMs Insurer is
obtained (provided, that such prior written consent shall not be required in the
event that the Servicing Rights Pledgee or its designee is so appointed as
Successor Servicer) and written notice of such proposed appointment shall have
been provided by the Securities Administrator to each Certificateholder. The
Master Servicer 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 Master Servicer, unless the Master Servicer 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 Master Servicer 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 Master Servicer and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Neither the Master Servicer nor any other
successor servicer shall be deemed to be in default hereunder by reason of any
failure to make, or any delay in making, any distribution hereunder or any
portion thereof or any failure to perform, or any delay in performing, any
duties or responsibilities hereunder, in either case caused by the failure of
the Servicer to deliver or provide, or any delay in delivering or providing, any
cash, information, documents or records to it.

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

      In the event that the Servicer shall for any reason no longer be the
Servicer hereunder (including by reason of any Event of Default),
notwithstanding anything to the contrary above or anything to the contrary which
may be set forth in Section 3.04, the Securities Administrator, the Trustee, the
Master Servicer, the Depositor and the NIMS Insurer hereby agree that within 10
Business Days of delivery to the Trustee by the Servicing Rights Pledgee of a
letter signed by the Servicer whereby the Servicer shall resign as Servicer
under this Agreement, or within 10 days of Securities Administrator's
termination of the Servicer pursuant to Section 7.01 or 7.02, the Servicing
Rights Pledgee or its designee shall be appointed as successor servicer;
provided that at the time of such appointment (i) the Servicing Rights Pledgee
or such designee meets the requirements of a successor servicer set forth above
in this Section 7.03 (provided that the consent and approval of the Securities
Administrator, the Trustee, the Master Servicer, the Depositor and the NIMs
Insurer shall be deemed to have been given to the Servicing Rights Pledgee or
its designee, and the Servicing Rights Pledgee and its designee are hereby
agreed to be acceptable to the Securities Administrator, the Trustee, the Master
Servicer, the Depositor and the NIMs Insurer) and (ii) the Servicing Rights
Pledgee or such designee agrees to be subject to the terms of this Agreement.

      SECTION 7.04. Notification to Certificateholders.

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

                                     -122-
<PAGE>

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

                                  ARTICLE VIII

             CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

      SECTION 8.01. Duties of the Trustee and the Securities Administrator.

      The Trustee and the Securities Administrator, prior to the occurrence of
an Event of Default and after the curing of all Events of Default that may have
occurred, each 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.

      Each of the Trustee and the Securities Administrator, upon receipt of all
resolutions, certificates, statements, opinions, reports, documents, orders or
other instruments furnished to the Trustee that are specifically required to be
furnished pursuant to any provision of this Agreement, shall examine them to
determine whether they conform on their face to the requirements of this
Agreement. If any such instrument is found not to conform to the requirements of
this Agreement in a material manner, the Trustee or the Securities
Administrator, as the case may be, shall take such action as it deems
appropriate to have the instrument corrected and if the instrument is not
corrected to the its satisfaction, the Securities Administrator will provide
notice to the Certificateholders and the NIMs Insurer and take such further
action as directed by the Certificateholders and the NIMs Insurer.

      No provision of this Agreement shall be construed to relieve the Trustee
or the Securities Administrator 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, and at all times, the duties and obligations of the
Securities Administrator shall be determined solely by the express provisions of
this Agreement, neither the Trustee nor the Securities Administrator shall be
liable, individually or as Trustee or Securities Administrator, as applicable,
except for the performance of such duties and obligations as are specifically
set forth in this Agreement, no implied covenants or obligations shall be read
into this Agreement against the Trustee or the Securities Administrator and, the
Trustee and the Securities Administrator 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 or the Securities
Administrator and conforming to the requirements of this Agreement that it
reasonably believed in good

                                     -123-
<PAGE>

faith to be genuine and to have been duly executed by the proper authorities
respecting any matters arising hereunder;

                  (ii) neither the Trustee nor the Securities Administrator
shall, individually or as Trustee or Securities Administrator, as applicable, be
liable for an error of judgment made in good faith by a Responsible Officer or
Responsible Officers of the Trustee unless the Trustee or Securities
Administrator, as applicable, was negligent or acted in bad faith or with
willful misfeasance; and

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

      SECTION 8.02. Certain Matters Affecting the Trustee and the Securities
Administrator.

            (a) Except as otherwise provided in Section 8.01:

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

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

                  (iii) neither the Trustee nor the Securities Administrator

the occurrence of an Event of Default hereunder and after the curing of all
Events of Default that may have occurred, the Trustee, in each case, 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 and the Securities Administrator may execute
any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents, custodians, accountants or attorneys or
independent contractors and the Trustee and the Securities Administrator will
not be responsible for any misconduct or negligence on the part of any agent,
custodian, accountant, attorney or independent contractor appointed with due
care by it hereunder;

                  (vi) neither the Trustee nor the Securities Administrator
shall 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;

                                     -124-
<PAGE>
                  (vii) neither the Trustee nor the Securities Administrator
shall be liable, individually or as Trustee or Securities Administrator, as
applicable, for any loss on any investment of funds pursuant to this Agreement
(other than as issuer of the investment security);

                  (viii) neither the Trustee nor the Securities Administrator
shall be deemed to have knowledge of an Event of Default until a Responsible
Officer of the Trustee or the Securities Administrator, as applicable, 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 shall appoint
the Servicer as the trustee's attorney-in-fact in order to carry out and perform
certain activities that are necessary or appropriate for the servicing and
administration of the Mortgage Loans pursuant to this Agreement. Such
appointment shall be evidenced by a power of attorney in such form as may be
agreed to by the Trustee and the Servicer. The Trustee shall have no liability
for any action or inaction of the Servicer in connection with such power of
attorney and the Trustee shall be indemnified by the Servicer for all
liabilities, costs, expenses incurred by the Trustee in connection with the
Servicer's use or misuse of such powers of attorney.

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

Servicer makes any representation as to the validity or sufficiency of this
Agreement, of any Mortgage Loan, or any related document other than with respect
to the execution and authentication of the Certificates, if it so executed or
authorized the Certificates. The Trustee shall not be accountable for the use or
application by the Depositor, the Securities Administrator, the Master Servicer
or the Servicer of any funds paid to the Depositor, the Securities
Administrator, the Master Servicer or the Servicer in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account or the
Certificate Account by the Depositor, the Securities Administrator, the Master
Servicer or the Servicer.

      SECTION 8.04. Trustee and Securities Administrator May Own Certificates.

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

      SECTION 8.05. Trustee's and Securities Administrator's Fees and Expenses.

      The Securities Administrator shall be entitled to receive on each
Distribution Date the Securities Administrator Fee. The Securities Administrator
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as shall be agreed to in writing by the
Securities Administrator and the Trustee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee.

      SECTION 8.06. Indemnification and Expenses of Trustee.

            (a) 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

                                     -126-
<PAGE>

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 in the aggregate in any calendar year, excluding
(i) any Servicing Transfer Costs and (ii) any costs, damages or expenses
incurred by the Trustee in connection with any "high cost" home loans or any
predatory or abusive lending laws, which amounts shall in no case be subject to
any such limitation; provided, however, that such cap shall apply only if NIM
Notes have been issued and shall cease to apply after the date on which any NIM
Notes are paid in full and all amounts which the NIMs Insurer is entitled to be
paid or reimbursed shall have been paid or reimbursed. Any amounts not in excess
of this cap may be withdrawn by the Trustee from the Certificate Account at any
time

      SECTION 8.07. Eligibility Requirements for Trustee.

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

                                     -127-
<PAGE>

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 Securities Administrator 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.

      If the Securities Administrator and the Master Servicer are the same
Person, then at any time the Securities Administrator resigns or is removed
hereunder, the Master Servicer shall likewise be terminated as master servicer
hereunder.

      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 Securities Administrator 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

                                     -128-
<PAGE>

(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:

                  (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

                                     -129-
<PAGE>

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, the Securities Administrator and the Depositor.

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

      SECTION 8.12. Tax Matters.

      (A) It is intended that each of the REMICs provided for herein shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such REMIC to qualify as, a "real estate mortgage investment conduit"
as defined in and in accordance with the REMIC Provisions. It is also intended
that each of the grantor trusts provided for in Section 2.07 hereof shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such grantor trust to qualify as, a grantor trust under the
provisions of Subpart E, Part I of Subchapter J of the Code. In furtherance of
such intention, the Securities Administrator covenants and agrees that it shall
act as agent (and the Securities Administrator is hereby appointed to act as
agent) on behalf of each of the REMICs provided for herein and that in such
capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a
timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return
(Form 1066 or any successor form adopted by the Internal Revenue Service) and
prepare and file or cause to be prepared and filed with the Internal Revenue
Service and applicable state or local tax authorities income tax or information
returns for each taxable year with respect to each of the REMICs and grantor
trusts provided for herein, containing such information and at the times and in
the manner as may be required by the Code or state or local tax laws,
regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty days of the Closing
Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms
8811 or as otherwise may be required by the Code, the name, title, address, and
telephone number of the person that the holders of the Certificates may contact
for tax information relating thereto, together with such additional information
as may be required by such Form, and update such information at the time or
times in the manner required by the Code for each of the REMICs provided for
herein; (c) make or cause to be made elections, on behalf of each of the REMICs
provided for herein to be treated as a REMIC on the federal tax return of such
REMICs for their first taxable years (and, if necessary, under applicable state
law); (d) prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary, state
tax authorities, all information returns and reports as and when required to be
provided to them in accordance with the REMIC Provisions or other applicable
law, including without limitation, the calculation of any original issue
discount using the Prepayment Assumption; (e) provide information necessary for
the computation of tax imposed on the transfer of a Class R Certificate to a
Person that is not a Permitted Transferee, or an agent (including a broker,
nominee or other middleman) of a Person that is not a Permitted Transferee, or a
pass through entity in which a Person that is not a Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct the affairs of each of the REMICs
and grantor trusts provided for herein at all times that any Certificates are
outstanding so as to maintain the status of each of the REMICs provided for
herein as a REMIC under the REMIC Provisions and the status of each of the
grantor trusts provided for herein as a grantor trust under Subpart E, Part I of
Subchapter J of the Code; (g) not knowingly or intentionally

                                     -130-
<PAGE>

take any action or omit to take any action that would cause the termination of
the REMIC status of any of the REMICs provided for herein or result in the
imposition of tax upon any such REMIC; (h) not knowingly or intentionally take
any action or omit to take any action that would cause the termination of the
grantor trust status under Subpart E, Part I of Subchapter J of the Code of any
of the grantor trusts provided for herein or result in the imposition of tax
upon any such grantor trust; (i) pay, from the sources specified in the last
paragraph of this Section 8.12, 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 Securities
Administrator from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (j) sign or cause to be signed federal, state
or local income tax or information returns; (k) maintain records relating to
each of the REMICs provided for herein, including but not limited to the income,
expenses, assets and liabilities of each of the REMICs and grantor trusts
provided for herein, and the fair market value and adjusted basis of the Trust
Fund property determined at such intervals as may be required by the Code, as
may be necessary to prepare the foregoing returns, schedules, statements or
information; and (l) as and when necessary and appropriate, represent each of
the REMICs 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 Securities Administrator to perform its duties as
set forth herein, the Depositor shall provide, or cause to be provided, to the
Securities Administrator within 10 days after the Closing Date all information
or data that the Securities Administrator 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 Securities Administrator promptly
upon written request therefor, any such additional information or data that the
Securities Administrator may, from time to time, request in order to enable the
Securities Administrator to perform its duties as set forth herein. The
Depositor hereby agrees to indemnify the Securities Administrator for any
losses, liabilities, damages, claims or expenses of the Securities Administrator
arising from any errors or miscalculations of the Securities Administrator that
result from any failure of the Depositor to provide, or to cause to be provided,
accurate information or data to the Securities Administrator on a timely basis.

      In the event that any tax is imposed on "prohibited transactions" of any
of the REMICs provided for herein as defined in Section 860F(a)(2) of the Code,
on the "net income from foreclosure property" of any of such REMICs as defined
in Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Securities Administrator, if any such other tax arises out of or results
from a breach by the Securities Administrator of any of its obligations under
this Agreement or as a result of the location of the Securities Administrator,
(ii) any party hereto (other than the Securities Administrator) to the extent
any such other tax arises out of or results from a breach by such other party of
any of its obligations under this Agreement or as a result of the location of
such other party or (iii) in all other cases, or in the event that any liable
party here fails to honor its obligations under the preceding clauses (i) or
(ii), any such tax will be paid first with amounts (other than amounts derived
by the Trust Fund from a payment on the Cap Contracts) 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 Contracts) otherwise to be distributed to all other
Certificateholders in the following order of priority: first, to the Class C
Certificates (pro rata), second to the Class B-4 Certificates (pro rata), third
to the Class B-3 Certificates (pro rata), fourth to the Class B-2 Certificates
(pro rata), fifth to the Class B-1 Certificates (pro rata), sixth to the Class
M-6 Certificates

                                     -131-
<PAGE>

(pro rata), seventh to the Class M-5 Certificates (pro rata), eighth to the
Class M-4 Certificates (pro rata), ninth to the Class M-3 Certificates (pro
rata), tenth to the Class M-2 Certificates (pro rata), eleventh to the Class M-1
Certificates (pro rata) and twelfth to the Class A Certificates (pro rata).
Notwithstanding anything to the contrary contained herein, to the extent that
such tax is payable by the Class R Certificate, the Securities Administrator 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 Securities Administrator 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, Securities Administrator and the Trustee agrees
not to take or omit to take knowingly or intentionally, 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 Auction of all Mortgage
Loans.

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

            (b) On or before the Determination Date following the Initial
Optional Termination Date, the Trustee will attempt to terminate the Trust Fund
through a one-time auction process and thereby effect the retirement of all of
the Certificates. The Trustee will attempt to auction the remaining Trust Fund
assets via a solicitation of bids from at least three bidders. The Trustee will
solicit bids from each Holder of a Class C and Class P Certificate. Any such
termination will occur only if the highest bid received is at least equal to the
Optional Termination Price. Proceeds from the purchase will be distributed to
the Certificateholders in the order of priority described herein. Any such
Optional Termination will result in an early retirement of the Certificates.

                  If the Trust Fund is not terminated because a sufficient
purchase price is not achieved at such auction, the NIMs Insurer, if any, may
purchase all of the Mortgage Loans, which would result in an early retirement of
the Certificates and the termination of the Trust Fund. If the auction fails to
achieve a sufficient purchase price and the NIMs Insurer, if any, fails to
exercise its option to purchase all of the Mortgage Loans, the Servicer may
purchase all of the Mortgage Loans at the Optional Termination Price, which
similarly would result in an early retirement of the Certificates and the
termination of the Trust Fund.

                                     -132-
<PAGE>

      SECTION 9.02. Final Distribution on the Certificates.

      If on any Determination Date, (i) the Securities Administrator 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 Securities
Administrator shall send a final distribution notice promptly to each
Certificateholder and the NIMs Insurer or (ii) the Securities Administrator
determines that a Class of Certificates shall be retired after a final
distribution on such Class, the Securities Administrator 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
Securities Administrator specified in such notice.

      Notice of any termination of the Trust Fund, specifying the Distribution
Date on which Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the
Securities Administrator by letter to Certificateholders mailed no later than
the last calendar 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 Securities Administrator 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 Securities Administrator 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, certification to the Trustee that
such required amount has been deposited in the Trust Fund and the receipt by the
Trustee of a Request for Release therefor, the Trustee shall promptly release to
the Mortgage Files for the Mortgage Loans.

      Upon presentation and surrender of the Certificates, the Securities
Administrator 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 Securities Administrator 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 Securities
Administrator 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, neither the
Securities Administrator nor the Trustee shall have any further duties or
obligations with respect thereto.

      SECTION 9.03. Additional Termination Requirements.

            (a) In the event the Servicer completes an Optional Termination as
provided in Section 9.01, the Trust Fund shall be terminated in accordance with
the following additional requirements, unless the Trustee has been supplied with
an Opinion of Counsel, at the expense of the Trustee, the NIMs Insurer or
Servicer, 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 and the Securities Administrator thereof, and the
Securities Administrator shall in turn specify the first day of such period in a
statement attached to the final tax returns of each of the REMICs provided for
herein pursuant to Treasury Regulation Section 1.860F-1. The Depositor shall
satisfy all the requirements of a qualified liquidation under Section 860F of
the Code and any regulations thereunder, as evidenced by an Opinion of Counsel
obtained at the expense of the Servicer;

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

                  (iii) At the time of the making of the final payment on the
Certificates, the Securities Administrator shall distribute or credit, or cause
to be distributed or credited, to the Class R Certificateholders all cash on
hand (other than cash retained to meet outstanding claims), and the Trust Fund
shall terminate at that time, whereupon neither the Securities Administrator nor
the Trustee shall have any further duties or obligations with respect to sums
distributed or credited to the Class R Certificateholders.

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

            (c) Upon the written request of the Depositor, the Trustee as agent
for each REMIC hereby agrees to adopt and sign a plan of complete liquidation as
provided to it by the Depositor. The Trustee's obligation to adopt and sign such
plan of complete liquidation is subject to the Trustee's receipt of the Opinion
of Counsel referred to in Section 9.03(a)(i). In addition, the Trustee shall
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
Master Servicer, the Servicer, the Securities Administrator and the Trustee,
with the consent of the NIMs Insurer and without the consent of any of the
Certificateholders to,

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

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

                                     -134-
<PAGE>

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

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

      Notwithstanding the foregoing, without the consent of the
Certificateholders, the Depositor, the Master Servicer, the Servicer, the
Securities Administrator 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, the NIMs Insurer and the Securities Administrator
shall have been provided an Opinion of Counsel addressed to the Trustee, which
opinion shall be an expense of the party requesting such amendment but in any
case shall not be an expense of the Trustee, the NIMs Insurer or the Securities
Administrator, 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
Master Servicer, the Servicer, the Securities Administrator and the Trustee and
the Holders of the Certificates affected thereby evidencing not less than
66-2/3% of the Voting Rights, with the consent of the NIMs Insurer, for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of
the Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the Holders of Certificates of such Class evidencing
66-2/3% or more of the Voting Rights of such Class or (iii) reduce the aforesaid
percentages of Certificates the Holders of which are required to consent to any
such amendment without the consent of the Holders of all such Certificates then
outstanding.

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

      Promptly after the execution of any amendment to this Agreement requiring
the consent of Certificateholders, the Trustee or upon the written request of
the Trustee to the Securities Administrator,

                                     -135-
<PAGE>

the Securities Administrator shall furnish written notification of the substance
of such amendment to each Certificateholder and each Rating Agency.

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

      Nothing in this Agreement shall require the Trustee or the Securities
Administrator to enter into an amendment without receiving an Opinion of
Counsel, satisfactory to the Trustee or the Securities Administrator 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 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.

                                     -136-
<PAGE>

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

      SECTION 10.05. Notices.

            (a) The Securities Administrator 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, the
Securities Administrator, the Master Servicer 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.

            (b) The Securities Administrator 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

All directions, demands and notices hereunder shall be in writing and shall be
deemed to have been duly given when delivered to (a) in the case of the

prepaid, to their respective addresses appearing in the Certificate Register.

      SECTION 10.06.       Severability of Provisions.

                                     -137-
<PAGE>

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

      SECTION 10.07. Assignment.

      Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the
Servicer without the prior written consent of the Securities Administrator and
Depositor.

      SECTION 10.08. Limitation on Rights of Certificateholders.

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

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

      No Certificateholder shall have any right by virtue or by availing itself
of any provisions of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, the Holders
of Certificates evidencing not less than 25% of the Voting Rights evidenced by
the Certificates shall also have made written request to the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses, and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after its receipt of such notice, request
and offer of indemnity shall have neglected or refused to institute any such
action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates and/or the NIMs
Insurer, or to obtain or seek to obtain priority over or preference to any other
such Holder and/or the NIMs Insurer or to enforce any right under this
Agreement, except in the manner herein provided and for the common benefit of
all Certificateholders. For the protection and enforcement of the provisions of
this Section 10.08, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

      SECTION 10.09. Inspection and Audit Rights.

      The Master Servicer and Servicer each agree that, on reasonable prior
notice, it will permit any representative of the Depositor or the Trustee during
the Master Servicer's or Servicer's normal business hours, to examine all the
books of account, records, reports and other papers of the Master Servicer or
Servicer relating to the Mortgage Loans, to make copies and extracts therefrom,
to cause such books to be

                                     -138-
<PAGE>
audited by independent certified public accountants selected by the Depositor or
the Trustee and to discuss its affairs, finances and accounts relating to the
Mortgage Loans with its officers, employees, agents, counsel and independent
public accountants (and by this provision the Master Servicer and the Servicer
each hereby authorizes such accountants to discuss with such representative such
affairs, finances and accounts), all at such reasonable times and as often as
may be reasonably requested. Any out-of-pocket expense incident to the exercise
by the Depositor or the Trustee of any right under this Section 10.09 shall be
borne by the party requesting such inspection; all other such expenses shall be
borne by the Servicer or Master Servicer, as the case may be.

      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
Securities Administrator 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.
With respect to the Securities Administrator, such obligation shall be satisfied
with the provision of access to the NIMs Insurer to the Securities
Administrator's website.

            (b) Wherever in this Agreement there shall be a requirement that
there be no downgrade, reduction, withdrawal or qualification of or other effect
on the rating of any Class of Certificates by any Rating Agency as of any date,
there also shall be deemed to be a requirement that there be no such effect on
any class of notes issued pursuant to the Indenture and guaranteed by the NIMs
Insurer as of such date. In addition, unless there exists a continuance of any
failure by the NIMs Insurer to make a required payment under the policy insuring
the NIM Notes (such event, a "NIMs Insurer Default"), wherever in this Agreement
there shall be a requirement that any Person or any communication, object or
other matter be acceptable or satisfactory to or otherwise receive the consent
or other approval of any other Person (whether as a condition to the eligibility
of such Person to act in any capacity, as a condition to any circumstance or
state of affairs related to such matter, or otherwise), there also shall be
deemed to be a requirement that such Person or matter be approved in writing by
the NIMs Insurer, which approval shall not be unreasonably withheld or delayed.

      Section 10.13. 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 10.13(e) below, under which (1) the Servicer
assigns or pledges its rights under this Agreement to be reimbursed

                                     -139-
<PAGE>

for any or all Advances and/or Servicing Advances to (i) a Person, which may be
a special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing Person agrees to fund all of the Advances and/or Servicing Advances
required to be made by the Servicer pursuant to this Agreement. No consent of
the NIMs Insurer, Securities Administrator, Trustee, Certificateholders or any
other party shall be required before the Servicer may enter into an Advance
Facility nor shall the NIMs Insurer, Securities Administrator, 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 Securities
Administrator and 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, (b) the identity of the Person (the "Servicer's
Assignee") that will, subject to Section 10.13(c) hereof, have the right to make
withdrawals from the Collection Account pursuant to Section 3.08 hereof to
reimburse previously unreimbursed Advances and/or Servicing Advances ("Advance
Reimbursement Amounts") and (c) that the Servicer's Assignee shall agree to be
bound by the provisions of this Section 10.13. The Advance Facility Notice shall
be executed by the Servicer, the Advance Financing Person and the Servicer's
Assignee. 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 3.08 hereof to the extent permitted under Section 10.13(e) below.

            (c) Notwithstanding the existence of an Advance Facility, the
Servicer, on behalf of the Advance Financing Person, shall be entitled to
receive reimbursements of Advances and/or Servicing Advances in accordance with
Section 3.08 hereof, which entitlement may be terminated by the Advance
Financing Person pursuant to a written notice to the Trustee in the manner set
forth in Section 10.05 hereof. Upon receipt of such written notice, the Servicer
shall no longer be entitled to receive reimbursement for any Advance
Reimbursement Amounts and the Servicer's Assignee shall immediately have the
right to receive from the Collection Account all Advance Reimbursement Amounts.
Notwithstanding the foregoing, and for the avoidance of doubt, (i) the Servicer
and/or the Servicer's Assignee shall only be entitled to reimbursement of
Advance Reimbursement Amounts hereunder pursuant to Section 3.08 of this
Agreement and shall not otherwise be entitled to make withdrawals of, or
receive, Advance Reimbursement Amounts that shall be deposited in the Collection
Account pursuant to Section 3.05 hereof, and (ii) none of the Trustee or the
Certificateholders shall have any right to, or otherwise be entitled to, receive
any Advance Reimbursement Amounts to which the Servicer or Servicer's Assignee,
as applicable, shall be entitled pursuant to Section 3.08 hereof. Without
limiting the foregoing, none of the Trustee, the NIMs Insurer, the Master
Servicer, the Securities Administration or the Certificateholders shall have any
right of set-off against Advance Reimbursement

                                     -140-
<PAGE>

Amounts hereunder. 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. Upon an Event of Default or if the Trustee
otherwise shall reasonably request, the Servicer shall maintain and provide to
any successor servicer or the Trustee as successor servicer a detailed
accounting on a loan-by-loan basis as to amounts advanced by, pledged or
assigned to, and reimbursed to any Advance Financing Person (and such successor
servicer or Trustee may rely on 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 certification of a Servicing Officer of the
Servicer made pursuant to Section 4.01, any Nonrecoverable Advance or
Nonrecoverable 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 Nonrecoverable
Advance or Nonrecoverable 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) None of the Trustee, the Securities Administrator or the Master
Servicer shall, as a result of the existence of any Advance Facility, have any
additional duty or liability with respect to the payment of any Advance
Reimbursement Amount, have any additional responsibility to track or monitor
Advance Reimbursement Amounts or any Advance Facility, and, is not and shall not
be obligated to make any payment with respect to any Advance Reimbursement
Amount.

            (h) None of the Depositor, the Securities Administrator, the Master
Servicer 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, the Securities
Administrator, the Master Servicer 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 Securities Administrator, the Master
Servicer, the Trustee, any successor servicer and the Trust Fund for any claim,
loss, liability or damage resulting from any claim by the related Advance
Financing Person, except to the extent that such claim, loss, liability or
damage resulted from or arose out of negligence, recklessness or willful
misconduct on the part of the Depositor, the Trustee or any successor servicer,
as the case may be, or failure by the successor servicer or the Trustee, as the
case may be, to remit funds as required by this Agreement or the commission of
an act or omission to act by the successor servicer or the Trustee, as the case
may be, and the passage of

                                     -141-
<PAGE>

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.

                                   ARTICLE XI

            ADMINISTRATION AND MASTER SERVICING OF THE MORTGAGE LOANS

      Section 11.01. Master Servicer.

      The Master Servicer shall supervise, monitor and oversee the obligation of
the Servicer to service and administer the Mortgage Loans in accordance with the
terms of this Agreement and shall have full power and authority to do any and
all things which it may deem necessary or desirable in connection with such
master servicing and administration. In performing its obligations hereunder,
the Master Servicer shall act in a manner consistent with Accepted Master
Servicing Practices. Furthermore, the Master Servicer shall oversee and consult
with the Servicer as necessary from time to time to carry out the Master
Servicer's obligations hereunder, shall receive, review and evaluate all
reports, information and other data provided to the Master Servicer by the
Servicer and shall cause the Servicer to perform and observe the covenants,
obligations and conditions to be performed or observed by the Servicer under
this Agreement. The Master Servicer shall independently and separately monitor
the Servicer's servicing activities with respect to each related Mortgage Loan,
reconcile the results of such monitoring with such information provided in the
previous sentence on a monthly basis and coordinate corrective adjustments to
the Servicer's and Master Servicer's records, and based on such reconciled and
corrected information, prepare any other information and statements required to
be provided by the Master Servicer hereunder. Except during any time where the
Master Servicer is acting as servicer hereunder, neither the Master Servicer nor
the Securities Administrator shall have any responsibility for reviewing or
reconciling the Collection Account or for any expenses or other consequences
resulting from any failure of such Collection Account to be so reconciled.

      The Trustee shall furnish the Servicer and/or the Master Servicer with any
limited powers of attorney and other documents in form as provided to it
necessary or appropriate to enable the Servicer and/or the Master Servicer to
execute in the name of the Trustee, as applicable, all documents reasonably
required to perform the servicing functions described in Article III or this
Article XI. The Trustee shall have no responsibility for any action of the
Master Servicer or the Servicer pursuant to any such limited power of attorney
and shall be indemnified by the Master Servicer or the Servicer, as applicable,
for any cost, liability or expense incurred by the Trustee in connection with
such Person's misuse of any such power of attorney.

      The Master Servicer and the Securities Administrator shall provide access

Securities Administrator regarding the related Mortgage Loans and REO Property
and the master servicing and servicing thereof to the Certificateholders, the
FDIC, and the supervisory agents and examiners of the FDIC, such access being
afforded only upon reasonable prior written request and during normal business
hours at the office of the Master Servicer or the Securities Administrator;
provided, however, that, unless otherwise required by law, neither of the Master
Servicer nor the Securities Administrator shall be required to provide access to
such records and documentation if the provision thereof would violate the legal
right to privacy of any Mortgagor. The Master Servicer and the Securities
Administrator shall allow representatives of the above entities to photocopy any
of the records and documentation and shall provide equipment for that purpose at
a charge that covers the Master Servicer's or the Securities Administrator's
actual costs.

other Mortgage Loan Document; (iii) obtain a deficiency judgment against the

      Section 11.02. Monitoring of Servicer.

            (a) The Master Servicer shall be responsible for monitoring the
compliance by the Servicer with its duties under this Agreement. In the review
of the Servicer's activities, the Master Servicer may rely upon an Officer's
Certificate of the Servicer with regard to the Servicer's compliance with the
terms of this Agreement. In the event that the Master Servicer, in its judgment,
determines that the Servicer should be terminated in accordance with the terms
hereof, or that a notice should be sent pursuant to the terms hereof with
respect to the occurrence of an event that, unless cured, would constitute a
Servicer Event of Default, the Master Servicer shall notify the Servicer, the
Seller and the Trustee thereof and the Master Servicer shall issue such notice
or take such other action as it deems appropriate.

            (b) The Master Servicer, for the benefit of the Securities
Administrator and the Certificateholders, shall enforce the obligations of the
Servicer under this Agreement and shall, in the event that the Servicer fails to
perform its obligations in accordance with this Agreement, subject to the
preceding paragraph, Section 3.04 and Article VII, terminate the rights and
obligations of the Servicer hereunder in accordance with the provisions of
Article VII. Such enforcement, including, without limitation, the legal
prosecution of claims and the pursuit of other appropriate remedies, shall be in
such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, provided that the Master Servicer shall not be
required to prosecute or defend any legal action except to the extent that the
Master Servicer shall have received reasonable indemnity for its costs and
expenses in pursuing such action.

            (c) Upon termination of the rights of the Servicer upon the
Servicer's failure to perform its obligations in accordance with this Agreement,
the Master Servicer shall be entitled to be reimbursed by the Servicer (or from
amounts on deposit in the Collection Account if the Servicer is unable to
fulfill its obligations hereunder) for all reasonable out-of-pocket or third
party costs associated with the transfer of servicing from a predecessor
Servicer (or if the predecessor Servicer is the Master Servicer, from the
Servicer immediately preceding the Master Servicer), including, without
limitation, any reasonable out-of-pocket or third party costs or expenses
associated with the complete transfer of all servicing data and the completion,
correction or manipulation of such servicing data as may be required by the
Master Servicer to correct any errors or insufficiencies in the servicing data
or otherwise to enable the Master Servicer to service the Mortgage Loans
properly and effectively, upon presentation of reasonable documentation of such
costs and expenses.

            (d) The Master Servicer shall require the Servicer to comply with
the remittance requirements and other obligations set forth in this Agreement.

            (e) If the Master Servicer acts as successor to the Servicer, it
will not assume liability for the representations and warranties of the
terminated Servicer.

      Section 11.03. Fidelity Bond.

      The Master Servicer, at its expense, shall maintain in effect a blanket
fidelity bond and an errors and omissions insurance policy, affording coverage
with respect to all directors, officers, employees

                                     -143-
<PAGE>

and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The errors and omissions insurance policy and the fidelity bond shall be in such
form and amount generally acceptable for entities serving as master servicers or
trustees.

      Section 11.04. Power to Act; Procedures.

      The Master Servicer shall master service the Mortgage Loans and shall have
full power and authority, subject to the REMIC Provisions and the provisions of
Section 8.12, to do any and all things that it may deem necessary or desirable
in connection with the master servicing and administration of the Mortgage
Loans, including but not limited to the power and authority (i) to execute and
deliver, on behalf of the Certificateholders and the Trustee, customary consents
or waivers and other instruments and documents, (ii) to consent to transfers of
any Mortgaged Property and assumptions of the Mortgage Notes and related
Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and
(iv) to effectuate foreclosure or other conversion of the ownership of the
Mortgaged Property securing any Mortgage Loan, in each case, in accordance with
the provisions of this Agreement; provided, however, that the Master Servicer
shall not (and, consistent with its responsibilities under Section 11.02, shall
not permit the Servicer to) knowingly or intentionally take any action, or fail
to take (or fail to cause to be taken) any action reasonably within its control
and the scope of duties more specifically set forth herein, that, under the
REMIC Provisions, if taken or not taken, as the case may be, would cause any
REMIC formed hereby to fail to qualify as a REMIC or result in the imposition of
a tax upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) unless the
Master Servicer has received an Opinion of Counsel (at the expense of the Master
Servicer) to the effect that the contemplated action will not cause any REMIC
formed hereby to fail to qualify as a REMIC or result in the imposition of a tax
upon any REMIC. The Trustee shall furnish the Master Servicer, upon written
request from a Servicing Officer, with any powers of attorney empowering the
Master Servicer to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose upon
or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in
any court action relating to the Mortgage Loans or the Mortgaged Property, in
accordance with this Agreement, and the Trustee shall execute and deliver such
other documents, as the Master Servicer may request, to enable the Master
Servicer to master service and administer the Mortgage Loans and carry out its
duties hereunder, in each case in accordance with Accepted Master Servicing
Practices (and the Trustee shall have no liability for misuse of any such powers
of attorney by the Master Servicer and shall be indemnified by the Master
Servicer for any cost, liability or expense incurred by the Trustee in
connection with such Person's use or misuse of any such power of attorney). If
the Master Servicer or the Trustee has been advised that it is likely that the
laws of the state in which action is to be taken prohibit such action if taken
in the name of the Trustee or that the Trustee would be adversely affected under
the "doing business" or tax laws of such state if such action is taken in its
name, the Master Servicer shall join with the Trustee in the appointment of a
co-Trustee pursuant to Section 8.11. In the performance of its duties hereunder,
the Master Servicer shall be an independent contractor and shall not, except in
those instances where it is taking action in the name of the Trustee, be deemed
to be the agent of the Trustee.

      Section 11.05. Documents, Records and Funds in Possession of Master
Servicer to Be Held for Trustee.

            (a) The Master Servicer shall transmit to the Trustee such documents
and instruments coming into the possession of the Master Servicer from time to
time as are required by the terms hereof to be delivered to the Trustee. Any
funds received by the Master Servicer in respect of any Mortgage Loan or which
otherwise are collected by the Master Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan shall be deposited in the
Certificate Account. The

                                     -144-
<PAGE>

Master Servicer shall, and shall cause the Servicer to, provide access to
information and documentation regarding the Mortgage Loans to the Securities
Administrator, its agents and accountants at any time upon reasonable request
and during normal business hours, and to Certificateholders that are savings and
loan associations, banks or insurance companies, the OTS, the FDIC and the
supervisory agents and examiners of such Office and Corporation or examiners of
any other federal or state banking or insurance regulatory authority if so
required by applicable regulations of the Office of Thrift Supervision or other
regulatory authority, such access to be afforded without charge but only upon
reasonable request in writing and during normal business hours at the offices of
the Master Servicer designated by it. In fulfilling such a request the Master
Servicer shall not be responsible for determining the sufficiency of such
information.

            (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer, in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds
or Insurance Proceeds, shall be deposited in the Certificate Account.

      Section 11.06. Trustee to Retain Possession of Certain Insurance Policies
and Documents.

      The Trustee shall retain possession and custody of the originals (to the
extent available) of any primary mortgage insurance policies, or certificate of
insurance if applicable, and any certificates of renewal as to the foregoing as
may be issued from time to time as contemplated by this Agreement. Until all
amounts distributable in respect of the Certificates have been distributed in
full and the Master Servicer and the Servicer have otherwise fulfilled their
respective obligations under this Agreement, the Trustee shall also retain
possession and custody of each Mortgage File in accordance with and subject to
the terms and conditions of this Agreement. The Master Servicer shall promptly
deliver or cause to be delivered to the Trustee, upon the execution or receipt
thereof the originals of any primary mortgage insurance policies, any
certificates of renewal, and such other documents or instruments that constitute
the Mortgage File that come into the possession of the Master Servicer from time
to time.

      Section 11.07. Compensation for the Master Servicer and the Securities
Administrator.

      As compensation for the activities of the Master Servicer and the
Securities Administrator hereunder, the Master Servicer and the Securities
Administrator shall be entitled to a portion of the income from investment of or
earnings on the funds held from time to time in the Certificate Account, as
provided in Section 3.05(g). Each of the Master Servicer and the Securities
Administrator shall be required to pay all expenses incurred by it in connection
with its activities hereunder and shall not be entitled to reimbursement

certifies that [, except as set forth in Schedule A hereto,] as to each Mortgage

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

      2. We certify that (a) we have historically paid our debts as they became
due, (b) we intend, and believe that we will be able, to continue to pay our
debts as they become due in the future, (c) we understand that, as beneficial

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

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

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

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

      4. We certify that we are not an employee benefit plan subject to Title I
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), a
plan subject to Section 4975 of the

behalf of or with any assets of a Plan.

      5. We certify that (i) we are a U.S. person or (ii) we will hold the Class
R Certificate in connection with the conduct of a trade or business within the

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

any interest in the Class R Certificate, we will transfer such interest in the
Class R Certificate only (a) to a transferee that (i) is not a disqualified
organization and is not purchasing such interest in the Class R Certificate on
behalf of a disqualified organization, (ii) is a U.S. person or will hold the

                                    Pooling and Servicing Agreement

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

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

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

            3.    the Transferee is not a "disqualified organization" (as
                  defined below), has no plan or intention of becoming a
                  disqualified organization, and is not acquiring any of its
                  interest in the [TRUST NAME], Mortgage Loan Asset-Backed
                  Certificates, Series [______], Class R Certificate on behalf
                  of a disqualified organization or any other entity,

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

                  due,

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

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

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

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

            11.   IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE

                  fixed base (within the meaning of an applicable income tax
                  treaty) of the Transferee, and as to each of the residual
                  interests represented by the Class R Certificate, the present
                  value of

<PAGE>

                  the anticipated tax liabilities associated with holding such
                  residual interest does not exceed the sum of:

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

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

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

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

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

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

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

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

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