                         REPRESENTATIONS AND WARRANTIES

         Section 2.01. CONVEYANCE OF TRUST FUND.

         The Seller hereby sells, transfers, assigns, sets over and otherwise
conveys to the Depositor, without recourse, all the right, title and interest of
the Seller in and to the assets in the Trust Fund.

         The Seller has entered into this Agreement in consideration for the
purchase of the Mortgage Loans by the Depositor and has agreed to take the
actions specified herein.

         The Depositor, concurrently with the execution and delivery hereof,
hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee
for the use and benefit of the Certificateholders, without recourse, all the
right, title and interest of the Depositor in and to the Trust Fund.

         Concurrently with the execution and delivery of this Agreement, the
Depositor does hereby assign to the Trustee all of its rights and interest under
the Mortgage Loan Purchase Agreement, and all rights of the Seller and the
Depositor under the M&T Servicing Agreement and the GreenPoint Servicing
Agreement to the extent of the Mortgage Loans sold under the Mortgage Loan
Purchase Agreement. The Trustee hereby accepts such assignment, and shall be
entitled to exercise all rights of the Depositor under the Mortgage Loan
Purchase Agreement as if, for such purpose, it were the Depositor. The foregoing
sale, transfer, assignment, set-over, deposit and conveyance does not and is not
intended to result in creation or assumption by the Trustee of any obligation of
the Depositor, the Seller or any other Person in connection with the Mortgage
Loans, the M&T Servicing Agreement, the GreenPoint Servicing Agreement or any
other agreement or instrument relating thereto except as specifically set forth
herein. Any monetary obligation of the Seller as the purchaser or owner under
the M&T Servicing Agreement to M&T as Servicer and any monetary obligation of
the Seller as the purchaser or owner under the GreenPoint Servicing Agreement to
GreenPoint as Servicer following the Closing Date shall be satisfied by the
Trustee, as assignee of the Seller, only from funds then on deposit in the
Distribution Accounts.

         In connection with such sale, the Depositor does hereby deliver to, and
deposit with the Custodian pursuant to the Custodial Agreement the documents
with respect to each Mortgage Loan as described under Section 2 of the Custodial
Agreement (the "Mortgage Loan Documents"). In connection with such delivery and
as further described in the Custodial Agreement, the Custodian will be required
to review such Mortgage Loan Documents and deliver to the Trustee, the
Depositor, the Servicers and the Seller certifications (in the forms attached to
the Custodial Agreement) with respect to such review with exceptions noted
thereon. In addition, under the Custodial Agreement the Depositor will be
required to cure certain defects with respect to the Mortgage Loan Documents for
the related Mortgage Loans after the delivery thereof by the Depositor to the
Custodian as more particularly set forth therein.

         Notwithstanding anything to the contrary contained herein, the parties
hereto acknowledge that the functions of the Trustee with respect to the
custody, acceptance, inspection and release of the Mortgage Files and
preparation and delivery of the certifications shall be performed by the
Custodian pursuant to the terms and conditions of the Custodial Agreement.

         The Depositor shall deliver or cause to be delivered to the Servicers
copies of all trailing documents required to be included in the related Mortgage
File at the same time the originals or certified copies thereof are delivered to
the Custodian, such documents including the mortgagee policy of title insurance
and any Mortgage Loan Documents upon return from the recording office. The
Servicers shall not be responsible for any custodian fees or other costs
incurred in obtaining such documents and the Depositor shall cause the Servicers
to be reimbursed for any such costs the Servicers may incur in connection with
performing its obligations under this Agreement, the M&T Servicing Agreement and
the GreenPoint Servicing Agreement.

         Section 2.02. ACCEPTANCE OF THE MORTGAGE LOANS.

         (a) Based on the initial trust receipt received by it from the
Custodian pursuant to the Custodial Agreement, the Trustee acknowledges receipt,
subject to the provisions of Section 2.01 hereof and Section 2 of the Custodial
Agreement, of the Mortgage Loan Documents and all other assets included in the
definition of "REMIC I" and "REMIC II"under clauses (i), (ii) (iii), (v) and
(vi) (to the extent of amounts deposited into the related Distribution Account)
and declares that it holds (or the Custodian on its behalf holds) and will hold
such documents and the other documents delivered to it constituting a Mortgage
Loan Document, and that it holds (or the Custodian on its behalf holds) or will
hold all such assets and such other assets included in the definition of "REMIC
I" and "REMIC II" in trust for the exclusive use and benefit of all present and
future Group I Certificateholders and Group II Certificateholders.

         (b) In conducting the review of the Mortgage Files in accordance with
the Custodial Agreement, the Custodian on the Trustee's behalf will ascertain
whether all required documents have been executed and received and whether those
documents relate to the Mortgage Loans identified in Exhibit B to this
Agreement, as supplemented. If the Custodian finds any document constituting
part of the Mortgage File not to have been executed or received, or to be
unrelated to the Mortgage Loans identified in Exhibit B, the Seller shall
correct or cure any such defect or, if prior to the end of the second
anniversary of the Closing Date, the Seller may substitute for the related
Mortgage Loan a Replacement Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03 or shall deliver to the Trustee an Opinion of Counsel to the effect that
such defect does not materially or adversely affect the interests of the
Certificateholders in such Mortgage Loan within 60 days from the date of notice
from the Trustee of the defect and if the Seller fails to correct or cure the
defect or deliver such opinion within such period, the Seller will, subject to
Section 2.03, within 90 days from the notification of the Trustee purchase such
Mortgage Loan at the Purchase Price; provided, however, that if such defect
relates solely to the inability of the Seller to deliver the Mortgage,
assignment thereof to the Trustee, or intervening assignments thereof with
evidence of recording thereon because such documents have been submitted for
recording and have not been returned by the applicable jurisdiction, the Seller
shall not be required to purchase such

Mortgage Loan if the Seller delivers such documents promptly upon receipt, but
in no event later than 360 days after the Closing Date.

         (c) No later than 180 days after the Closing Date, the Custodian on the
Trustee's behalf will review, for the benefit of the Certificateholders, the
Mortgage Files and will execute and deliver or cause to be executed and
delivered to the Seller and the Trustee, a final trust receipt substantially in
the form annexed to the Custodial Agreement. In conducting such review, the
Custodian on the Trustee's behalf and in accordance with the terms of the
Custodial Agreement will ascertain whether each document required to be recorded
has been returned from the recording office with evidence of recording thereon
and the Custodian on the Trustee's behalf has received either an original or a
copy thereof, as required in the Custodial Agreement. If the Custodian finds
that any document with respect to a Mortgage Loan has not been received, or is
unrelated to the Mortgage Loans identified in Exhibit B or appears to be
defective on its face, the Custodian shall note such defect in the exception
report attached the final trust receipt issued pursuant to the Custodial
Agreement and the Seller shall correct or cure any such defect or, if prior to
the end of the second anniversary of the Closing Date, the Seller may substitute
for the related Mortgage Loan a Replacement Mortgage Loan, which substitution
shall be accomplished in the manner and subject to the conditions set forth in
Section 2.03 or shall deliver to the Trustee an Opinion of Counsel to the effect
that such defect does not materially or adversely affect the interests of
Certificateholders in such Mortgage Loan within 60 days from the date of notice
from the Trustee of the defect and if the Seller is unable within such period to
correct or cure such defect, or to substitute the related Mortgage Loan with a
Replacement Mortgage Loan or to deliver such opinion, the Seller shall, subject
to Section 2.03, within 90 days from the notification of the Trustee, purchase
such Mortgage Loan at the Purchase Price; provided, however, that if such defect
relates solely to the inability of the Seller to deliver the Mortgage,
assignment thereof to the Trustee or intervening assignments thereof with
evidence of recording thereon, because such documents have not been returned by
the applicable jurisdiction, the Seller shall not be required to purchase such
Mortgage Loan, if the Seller delivers such documents promptly upon receipt, but
in no event later than 360 days after the Closing Date.

         (d) In the event that a Mortgage Loan is purchased by the Seller in
accordance with subsections 2.02(a) or (b) above or Section 2.03, the Seller
shall remit the applicable Purchase Price to the Trustee for deposit in the
related Distribution Account and shall provide written notice to the Trustee
detailing the components of the Purchase Price, signed by an authorized officer.
Upon deposit of the Purchase Price in the related Distribution Account and upon
receipt of a request for release (in the form attached to the Custodial
Agreement) with respect to such Mortgage Loan, the Custodian, on behalf of the
Trustee, will release to the Seller the related Mortgage File and the Trustee
shall execute and deliver all instruments of transfer or assignment, without
recourse, furnished to it by the Seller, as are necessary to vest in the Seller
title to and rights under the Mortgage Loan. Such purchase shall be deemed to
have occurred on the date on which the deposit into the Distribution Account was
made. The Trustee shall promptly notify the Rating Agencies of such repurchase.
The obligation of the Seller to cure, repurchase or substitute for any Mortgage
Loan as to which a defect in a constituent document exists shall be the sole
remedies respecting such defect available to the Certificateholders or to the
Trustee on their behalf. The Seller shall promptly reimburse the Trustee for any
expenses incurred by the Trustee in respect of enforcing the remedies for such
breach.

         (e) The Seller shall deliver to the Custodian the Mortgage Note and
other documents constituting the Mortgage File with respect to any Replacement
Mortgage Loan, which the Custodian will review as provided in the Custodial
Agreement, provided, that the Closing Date referred to therein shall instead be
the date of delivery of the Mortgage File with respect to each Replacement
Mortgage Loan.

         or in violation of any statute, order or regulation of any court,

                           (v) No litigation is pending or, to the best of its
         knowledge, threatened in writing, against it that would materially and
         adversely affect the execution, delivery or enforceability of this
         Agreement or its ability to service the GMACM Mortgage Loans or to
         perform any of its other obligations under this Agreement in accordance
         with the terms hereof.

                           (vi) No consent, approval, authorization or order of
         any court or governmental agency or body is required for its execution,
         delivery and performance of, or compliance with, this Agreement or the

         legislation.

                           (viii) GMACM is a member of MERS in good standing,
         and will comply in all material respects with the rules and procedures

GMACM from any Person in accordance with the terms of this Agreement.

                  (b) The Seller hereby represents and warrants to and covenants
with, the Depositor, GMACM and the Trustee as follows, as of the Closing Date:

         hereto, constitutes a legal, valid and binding obligation of the
         Seller, enforceable against the Seller in accordance with its terms,
         except that (a) the enforceability hereof may be limited by bankruptcy,
         insolvency, moratorium, receivership and other similar laws relating to

         with respect to indemnity and contribution under applicable securities

         which it may be bound, or (C) constitute a material violation of any
         statute, order or regulation applicable to the Seller of any court,
         regulatory body, administrative agency or governmental body having
         jurisdiction over the Seller; and the Seller is not in breach or
         violation of any material indenture or other material agreement or

<PAGE>

         federal or local law or regulation or ordinance (or a similarly
         classified loan using different terminology under a law imposing
         heightened regulatory scrutiny or additional legal liability for
         residential mortgage loans having high interest rates, points and/or
         fees).

                           (ix) No loan is a High Cost Loan or Covered Loan, as
         applicable (as such terms are defined in Appendix E of the Standard &
         Poor's Glossary For File Format For LEVELS(R) Version 5.6 Revised
         (attached hereto as Exhibit N) and no mortgage loan originated on or

         Fair Lending Act.

                           (x) Any and all requirements of any federal, state or
         local law including, without limitation, usury, truth in lending, real
         estate settlement procedures, consumer credit protection, equal credit
         opportunity, fair housing, predatory, abusive lending or disclosure
         laws applicable to the origination and servicing of the Mortgage Loans
         have been complied with in all material respects.

         (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(b)(viii), (ix) and (x) and
Section 8 of the Mortgage Loan Purchase Agreement that materially and adversely
affects the interests of the Certificateholders in any Mortgage Loan, the party
discovering such breach shall give prompt written notice thereof to the other
parties. The Seller hereby covenants with respect to the representations and
warranties set forth in Section 2.03(b)(viii), (ix) and (x) and Section 8 of the
Mortgage Loan Purchase Agreement, that within 90 days of the discovery of a
breach of any representation or warranty set forth therein that materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
it shall cure such breach in all material respects and, if such breach is not so
cured, (i) prior to the second anniversary of the Closing Date, remove such
Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and substitute in
its place a Replacement Mortgage Loan, in the manner and subject to the
conditions set forth in this Section; or (ii) repurchase the affected Mortgage
Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set
forth below; provided that any such substitution pursuant to

                                      -63-
<PAGE>

(i) above or repurchase pursuant to (ii) above shall not be effected prior to
the delivery to the Trustee of an Opinion of Counsel if required by Section 2.05
and any such substitution pursuant to (i) above shall not be effected prior to
the additional delivery to the Custodian of a request for release in accordance
with the Custodial Agreement. The Seller shall promptly reimburse the Trustee
for any expenses reasonably incurred by the Trustee in respect of enforcing the
remedies for such breach. To enable the related Servicer to amend the Mortgage
Loan Schedule, the Seller shall, unless it cures such breach in a timely fashion
pursuant to this Section 2.03, promptly notify the Trustee whether it intends
either to repurchase, or to substitute for, the Mortgage Loan affected by such
breach. With respect to the representations and warranties in Section 8 of the
Mortgage Loan Purchase Agreement that are made to the best of the Seller's
knowledge, if it is discovered by any of the Depositor, the Seller or the
Trustee that the substance of such representation and warranty is inaccurate and
such inaccuracy materially and adversely affects the value of the related
Mortgage Loan, notwithstanding the Seller's lack of knowledge with respect to
the substance of such representation or warranty, the Seller shall nevertheless
be required to cure, substitute for or repurchase the affected Mortgage Loan in
accordance with the foregoing. Notwithstanding the foregoing, any breach of a
representation or warranty contained in clauses (xxxvii), (xxxviii), (xxxix),
(xl) and/or (xlv) of Section 8 of the Mortgage Loan Purchase Agreement shall be
automatically deemed to materially and adversely affect the interests of the
Certificateholders.

         With respect to any Replacement Mortgage Loan or Loans, the Seller
shall deliver to the Custodian for the benefit of the Certificateholders such
documents and agreements as are required by Section 2 of the Custodial
Agreement. No substitution will be made in any calendar month after the
Determination Date for such month. Scheduled Payments due with respect to
Replacement Mortgage Loans in the Due Period related to the Distribution Date on
which such proceeds are to be distributed shall not be part of the Trust Fund
and will be retained by the Seller. For the month of substitution, distributions
to Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for the related Due Period and thereafter the Seller shall be
entitled to retain all amounts received in respect of such Deleted Mortgage
Loan. The related Servicer shall amend the Mortgage Loan Schedule for the
benefit of the Certificateholders to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans and
shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon such
substitution, the Replacement Mortgage Loan or Loans shall be subject to the
terms of this Agreement in all respects, and the Seller shall be deemed to have
made with respect to such Replacement Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties set forth in Section 8 of the
Mortgage Loan Purchase Agreement with respect to such Mortgage Loan. Upon any
such substitution and the deposit into the Distribution Account of the amount
required to be deposited therein in connection with such substitution as
described in the following paragraph and receipt by the Custodian of a request
for release for such Mortgage Loan in accordance with the Custodial Agreement,
the Custodian on behalf of the Trustee shall release to the Seller the Mortgage
File relating to such Deleted Mortgage Loan and held for the benefit of the
Certificateholders and the Trustee shall execute and deliver at the Seller's
direction such instruments of transfer or assignment as have been prepared by
the Seller, in each case without recourse, as shall be necessary to vest in the
Seller, or its respective designee, title to the Trustee's interest in any
Deleted Mortgage Loan substituted

                                      -64-
<PAGE>

for pursuant to this Section 2.03. Neither the Trustee nor the Custodian shall
have any further responsibility with regard to such Mortgage File.

         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for a Deleted Mortgage Loan, the Trustee will determine the
amount (if any) by which the aggregate principal balance of all the Replacement
Mortgage Loans as of the date of substitution is less than the Stated Principal
Balance (after application of the principal portion of the Scheduled Payment due
in the month of substitution) of such Deleted Mortgage Loan. An amount equal to
the aggregate of such deficiencies, described in the preceding sentence for any
Distribution Date (such amount, the "Substitution Adjustment Amount") shall be
remitted to GMACM for deposit in the related Custodial Account if the Deleted
Mortgage Loan was serviced by GMACM or deposited into the related Distribution
Account if the Deleted Mortgage Loan was serviced by M&T or GreenPoint, by the
Seller delivering such Replacement Mortgage Loan on or before the Determination
Date for the Distribution Date relating to the Prepayment Period during which
the related Mortgage Loan was required to be purchased or replaced hereunder.

         In the event that the Seller shall have repurchased a Mortgage Loan,
the Purchase Price therefor shall be remitted to GMACM for deposit in the
related Custodial Account if the Purchase Price relates to a GMACM Mortgage Loan
or shall be deposited into the related Distribution Account if the Purchase
Price relates to an M&T Mortgage Loan or a GreenPoint Mortgage Loan, on or
before the Determination Date for the Distribution Date in the month following
the month during which the Seller was required to repurchase or replace such
Mortgage Loan and upon such deposit of the Purchase Price, the delivery of an
Officer's Certificate by GMACM to the Trustee certifying that the Purchase Price
for any GMACM Mortgage Loan repurchased pursuant to this Section has been
deposited in the related Custodial Account, the delivery of an Opinion of
Counsel if required by Section 2.05 and the receipt of a request for release
pursuant to the Custodial Agreement, the Custodian, on behalf of the Trustee
shall release the related Mortgage File held for the benefit of the
Certificateholders to the Seller, and the Trustee shall execute and deliver at
such Person's direction the related instruments of transfer or assignment
prepared by the Seller, in each case without recourse, as shall be necessary to
transfer title from the Trustee for the benefit of the Certificateholders and
transfer the Trustee's interest to the Seller to any Mortgage Loan purchased
pursuant to this Section 2.03. It is understood and agreed that the obligation
under this Agreement of the Seller to cure, repurchase or replace any Mortgage
Loan as to which a breach has occurred and is continuing shall constitute the
sole remedies against the Seller respecting such breach available to
Certificateholders, the Depositor or the Trustee.

         (d) The representations and warranties set forth in Section 2.03 shall
survive delivery of the respective Mortgage Loans and Mortgage Files to the
Trustee or the Custodian for the benefit of the Certificateholders.

         Section 2.04. REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR.

         The Depositor hereby represents and warrants to, and covenants, with
GMACM, the Seller and the Trustee as follows, as of the date hereof and as of

         duly authorized, by all necessary corporate action on its part, the
         execution, delivery and performance of this Agreement; and this
         Agreement, assuming the due authorization, execution and delivery
         hereof by the other parties hereto, constitutes a legal, valid and
         binding obligation of the Depositor, enforceable against the Depositor
         in accordance with its terms, subject, as to enforceability, to (i)
         bankruptcy, insolvency, moratorium receivership and other similar laws
         relating to creditors' rights generally and (ii) the remedy of specific
         performance and injunctive and other forms of equitable relief may be
         subject to equitable defenses and to the discretion of the court before
         which any proceeding therefor may be brought and further subject to
         public policy with respect to indemnity and contribution under
         applicable securities law.

                           (iii) The execution and delivery of this Agreement by
         the Depositor, the consummation of the transactions contemplated by
         this Agreement, and the fulfillment of or compliance with the terms
         hereof are in the ordinary course of business of the 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 material breach, violation or acceleration of, or result in
         a material default under, the terms of any other material agreement or
         instrument to which the 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 or the ability of the Depositor to
         perform its obligations under this 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 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.

                                      -66-

         The Depositor hereby represents and warrants to the Trustee as of the
Closing Date, following the transfer of the Mortgage Loans to it by the Seller,
the Depositor had good title to the Mortgage Loans and the related Mortgage
Notes were subject to no offsets, claims, defenses or counterclaims.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.04 shall survive delivery of the Mortgage Files to the
Trustee or the Custodian for the benefit of the Certificateholders. Upon
discovery by the Depositor, GMACM or the Trustee of a breach of such
representations and warranties, the party discovering such breach shall give
prompt written notice to the others and to each Rating Agency.

         Section 2.05. DELIVERY OF OPINION OF COUNSEL IN CONNECTION WITH
SUBSTITUTIONS AND REPURCHASES.

         (a) Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan that is not in default or as to which default is
not imminent, no repurchase or substitution pursuant to Sections 2.02 or 2.03
shall be made unless the Seller delivers to the Trustee an Opinion of Counsel,
addressed to the Trustee, to the effect that such repurchase or substitution
would not (i) result in the imposition of the tax on "prohibited transactions"
of REMIC I, REMIC II, REMIC III or REMIC IV or contributions after the Closing
Date, as defined in sections 860F(a)(2) and 860G(d) of the Code, respectively or
(ii) cause any of REMIC I, REMIC II, REMIC III or REMIC IV to fail to qualify as
a REMIC at any time that any Certificates are outstanding. Any Mortgage Loan as
to which repurchase or substitution was delayed pursuant to this paragraph shall
be repurchased or the substitution therefor shall occur (subject to compliance
with Sections 2.02 or 2.03) upon the earlier of (a) the occurrence of a default
or imminent default with respect to such Mortgage Loan and (b) receipt by the
Trustee of an Opinion of Counsel to the effect that such repurchase or
substitution, as applicable, will not result in the events described in clause
(i) or clause (ii) of the preceding sentence.

         (b) Upon discovery by the Depositor or the Seller 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 and the Trustee. In connection therewith, the Seller, at the
its option, shall either (i) substitute, if the conditions in Section 2.03(c)
with respect to substitutions are satisfied, a Replacement Mortgage Loan for the
affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90
days of such discovery in the same manner as it would a Mortgage Loan for a
breach of representation or warranty contained in Section 2.03. The Trustee
shall reconvey to the Seller 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. ISSUANCE OF THE GROUP I CERTIFICATES.

         The Trustee acknowledges the assignment to it of the Group I Mortgage
Loans and the delivery to the Custodian on its behalf of the related Mortgage
Files, subject to the provisions of Section 2.01 and Section 2.02, together with
the assignment to it of all other assets included in REMIC I, the receipt of
which is hereby acknowledged. The Group I Certificates constitute the

                                      -67-

entire beneficial ownership interest in REMIC I. The rights of the Holders of
the Group I Certificates to receive distributions from the proceeds of REMIC I

the assignment to it of all other assets included in REMIC II, the receipt of
which is hereby acknowledged. The interests evidenced by the Class R-1 Interest,
together with the REMIC II Regular Interests, constitute the entire beneficial
ownership interest in REMIC II. The rights of the Holders of the Class R-1
Interest and REMIC II (as holder of the REMIC II Regular Interests) to receive
distributions from the proceeds of REMIC II in respect of the Class R-1 Interest
and the REMIC II Regular Interests, respectively, and all ownership interests
evidenced or constituted by the Class R-1 Interest and the REMIC II Regular
Interests, shall be as set forth in this Agreement.

         Section 2.08. CONVEYANCE OF THE REMIC II REGULAR INTERESTS; ACCEPTANCE
OF REMIC III BY THE TRUSTEE.

         The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey to the Trustee,
without recourse all the right, title and interest of the Depositor in and to
the REMIC II Regular Interests for the benefit of the Class R-2 Interest and
REMIC III (as holder of the REMIC II Regular Interests). The Trustee
acknowledges receipt of the REMIC II Regular Interests and declares that it
holds and will hold the same in trust for the exclusive use and benefit of all
present and future Holders of the Class R-2 Interest and REMIC III (as holder of
the REMIC II Regular Interests). The rights of the Holders of the Class R-2
Interest and REMIC III (as holder of the REMIC II Regular Interests) to receive
distributions from the proceeds of REMIC III in respect of the Class R-2
Interest and REMIC III Regular Interests, respectively, and all ownership
interests evidenced or constituted by the Class R-2 Interest and the REMIC III

         Section 2.09. CONVEYANCE OF THE REMIC III REGULAR INTERESTS; ACCEPTANCE
OF REMIC IV BY THE TRUSTEE.

holds and will hold the same in trust for the exclusive use and benefit of all
present and future Holders of the Class R-3 Interest and REMIC IV (as holder of
the REMIC III Regular Interests). The rights of the Holder of the Class R-3

distributions from the proceeds of REMIC IV in respect of the Class R-3 Interest
and REMIC IV Regular Interests, respectively, and all ownership interests
evidenced or constituted by the Class R-3 Interest and the REMIC IV Regular
Interests, shall be as set forth in this

                                      -68-
<PAGE>

Agreement. The Class R-3 Interest and the REMIC IV Regular Interests shall
constitute the entire beneficial ownership interest in REMIC IV.

         Section 2.10. ISSUANCE OF CLASS II-R CERTIFICATES.

         The Trustee acknowledges the assignment to it of the REMIC II Regular
Interests and the REMIC III Regular Interests and, concurrently therewith and in
exchange therefor, pursuant to the written request of the Depositor executed by
an officer of the Depositor, the Trustee has executed, authenticated and
delivered to or upon the order of the Depositor, the Class II-R Certificates in
authorized denominations. The Class II-R Certificates evidence ownership in the
Class R-1 Interest, the Class R-2 Interest and the Class R-3 Interest.

         Section 2.11. ESTABLISHMENT OF TRUST.

         The Depositor does hereby establish, pursuant to the further provisions

Loan Trust, Series 2005-AP1" and does hereby appoint Wells Fargo Bank, National
Association, as Trustee in accordance with the provisions of this Agreement.

                                  ARTICLE III

            ADMINISTRATION AND SERVICING OF THE GMACM MORTGAGE LOANS

         Section 3.01. GMACM TO ACT AS SERVICER OF THE GMACM MORTGAGE LOANS.

         GMACM shall service and administer the GMACM Mortgage Loans on behalf
of the Trust and in the best interest of and for the benefit of the
Certificateholders (as determined by GMACM in its reasonable judgment) in
accordance with the terms of this Agreement and the GMACM Mortgage Loans and to
the extent consistent with such terms and in accordance with and exercising the
same care in performing those practices that GMACM customarily employs and
exercises in servicing and administering mortgage loans for its own account
(including, compliance with all applicable federal, state and local laws).

         To the extent consistent with the foregoing, GMACM shall seek the
timely and complete recovery of principal and interest on the Mortgage Notes
related to the GMACM Mortgage Loans and shall waive a Prepayment Charge only
under the following circumstances: (i) such waiver is standard and customary in
servicing similar mortgage loans and (ii) either (A) such waiver is related to a
default or reasonably foreseeable default and would, in the reasonable judgment
of GMACM, maximize recovery of total proceeds taking into account the value of
such Prepayment Charge and the related GMACM Mortgage Loan and, if such waiver
is made in connection with a refinancing of the related GMACM Mortgage Loan,
such refinancing is related to a default or a reasonably foreseeable default or
(B) such waiver is made in connection with a refinancing of the related GMACM
Mortgage Loan unrelated to a default or a reasonably foreseeable default where
(x) the related Mortgagor has stated to GMACM an intention to refinance the
related GMACM Mortgage Loan and (y) GMACM has concluded in its reasonable
judgment that the waiver of such Prepayment Charge would induce such Mortgagor
to refinance with GMACM or (iii) GMACM reasonably believes such Prepayment
Charge is unenforceable in accordance with applicable law or the collection of
such related Prepayment Charge would otherwise violate applicable law. If a
Prepayment Charge is waived as permitted by meeting both of the standards
described in clauses (i) and (ii)(B) above, then GMACM is required to pay the
amount of such waived Prepayment Charge (the "Servicer Prepayment Charge Payment
Amount"), for the benefit of the Holders of the Class I-P Certificates if the
waiver relates to a Group I Mortgage Loan or for the benefit of the Holders of
the Class II-P Certificates if the waiver relates to a Group II Mortgage Loan,
by depositing such amount into the Custodial Account within 90 days of notice or
discovery of such waiver meeting the standard set forth in both clauses (i) and
(ii)(B) above; provided, however, that GMACM shall not waive more than 5% of the
Prepayment Charges (by number of Prepayment Charges) set forth on the Prepayment
Charge Schedule in accordance with clauses (i) and (ii)(B) above.
Notwithstanding any other provisions of this Agreement, any payments made by
GMACM in respect of any waived Prepayment Charges pursuant to clauses (i) and
(ii)(B) above and the preceding sentence shall be deemed to be paid outside of
the Trust Fund.

         Subject only to the above-described applicable servicing standards (the
"Accepted Servicing Practices") and the terms of this Agreement and of the
respective GMACM Mortgage Loans, GMACM shall have full power and authority,
acting alone and/or through subservicers as

                                      -70-
<PAGE>

provided in Section 3.03, 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 related Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided herein), (iii) to collect any Insurance Proceeds and
other Liquidation Proceeds, and (iv) subject to Section 3.09, to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any GMACM Mortgage Loan.

         Without limiting the generality of the foregoing, GMACM, in its own
name or in the name of the Trust, the Depositor or the Trustee, is hereby
authorized and empowered by the Trust, the Depositor and the Trustee, when GMACM
believes it appropriate in its reasonable judgment, to execute and deliver, on
behalf of the Trustee, the Depositor, the Certificateholders or any of them, any
and all instruments of satisfaction or cancellation, or of partial or full
release or discharge and all other comparable instruments, with respect to the
GMACM Mortgage Loans, and with respect to the related Mortgaged Properties held
for the benefit of the Certificateholders. GMACM shall prepare and deliver to
the Depositor and/or the Trustee such documents requiring execution and delivery
by any or all of them as are necessary or appropriate to enable GMACM to service
and administer the GMACM Mortgage Loans. Upon receipt of such documents, the
Depositor and/or the Trustee shall execute such documents and deliver them to
GMACM. In addition, the Trustee shall execute, at the written request of GMACM,
and furnish to GMACM any special or limited powers of attorney agreeable to the
Trustee and its counsel for each county in which a Mortgaged Property is located
and other documents necessary or appropriate to enable GMACM to carry out its
servicing and administrative duties hereunder, provided such limited powers of
attorney or other documents shall be prepared by GMACM and submitted to the
Trustee for review prior to execution.

         In accordance with the standards of the first paragraph of this Section
3.01, GMACM 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 relating to the GMACM Mortgage Loans in order to preserve the lien on
the Mortgaged Property, which advances shall be reimbursable in the first
instance from related collections from the Mortgagors pursuant to Section 4.04,
and further as provided in Section 4.02. All costs incurred by GMACM, if any, in
effecting the payments of such taxes and assessments on the related 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 GMACM Mortgage Loans, notwithstanding
that the terms of such GMACM Mortgage Loans so permit.

         Section 3.02. DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS.

         (a) Except as otherwise provided in this Section 3.02, when any
Mortgaged Property relating to a GMACM Mortgage Loan has been or is about to be
conveyed by the Mortgagor, GMACM shall to the extent that it has knowledge of
such conveyance, enforce any due-on-sale clause contained in any Mortgage Note
or Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not

                                      -71-
<PAGE>

adversely affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, GMACM shall not be required to exercise such
rights with respect to a GMACM Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that GMACM 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, GMACM is authorized, subject to Section 3.02(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 related GMACM
Mortgage Loan shall continue to be covered (if so covered before GMACM enters
such agreement) by the applicable Required Insurance Policies. GMACM, subject to
Section 3.02(b), is also authorized with the prior approval of the insurers
under any Required Insurance Policies to enter into a substitution of liability
agreement with such Person, pursuant to which the original Mortgagor is released
from liability and such Person is substituted as Mortgagor and becomes liable
under the Mortgage Note. Notwithstanding the foregoing, GMACM shall not be
deemed to be in default under this Section 3.02(a) by reason of any transfer or
assumption that GMACM reasonably believes it is restricted by law from
preventing.

         (b) Subject to GMACM's duty to enforce any due-on-sale clause to the
extent set forth in Section 3.02(a), in any case in which a Mortgaged Property
related to a GMACM Mortgage 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 related GMACM Mortgage
Loan, GMACM shall prepare and deliver or cause to be prepared and delivered to
the Trustee for signature and shall direct, in writing, the Trustee to execute
the assumption agreement with the Person to whom the Mortgaged Property is to be
conveyed and such modification agreement or supplement to the Mortgage Note or
Mortgage or other instruments as are reasonable or necessary to carry out the
terms of the Mortgage Note or Mortgage or otherwise to comply with any
applicable laws regarding assumptions or the transfer of the Mortgaged Property
to such Person. In connection with any such assumption, no material term of the
Mortgage Note (including, but not limited to, the Mortgage Rate, the amount of
the Scheduled Payment and any other term affecting the amount or timing of
payment on the related Mortgage Loan) may be changed. In addition, the
substitute Mortgagor and the Mortgaged Property must be acceptable to GMACM in
accordance with the servicing standard set forth in Section 3.01. GMACM shall
notify the Trustee that any such substitution or assumption agreement has been
completed by forwarding to the Custodian the original of such substitution or
assumption agreement, which in the case of the original shall be added to the
related Mortgage File and shall, for all purposes, be considered a part of such
Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. Any fee collected by GMACM for entering into an
assumption or substitution of liability agreement will be retained by GMACM as
additional servicing compensation.

                                      -72-

         Section 3.03. SUBSERVICERS.

         GMACM shall perform all of its servicing responsibilities hereunder or
may cause a subservicer to perform any such servicing responsibilities on its
behalf, but the use by GMACM of a subservicer shall not release GMACM from any
of its obligations hereunder with respect to the related GMACM Mortgage Loans.
GMACM shall pay all fees of each of its subservicers from its own funds, and a
subservicer's fee shall not exceed the Servicing Fee payable to GMACM hereunder.

         At the cost and expense of GMACM, without any right of reimbursement
from its Custodial Account, GMACM shall be entitled to terminate the rights and
responsibilities of a subservicer and arrange for any servicing responsibilities
to be performed by a successor subservicer; provided, however, that nothing
contained herein shall be deemed to prevent or prohibit GMACM, at its option,
from electing to service the related GMACM Mortgage Loans itself. In the event
that GMACM's responsibilities and duties under this Agreement are terminated
pursuant to Section 8.03, GMACM shall at its own cost and expense terminate the
rights and responsibilities of each subservicer with respect to the GMACM
Mortgage Loans effective as of the date of GMACM's termination. GMACM shall pay
all fees, expenses or penalties necessary in order to terminate the rights and
responsibilities of each subservicer from GMACM's own funds without
reimbursement from the Trust Fund.

         Notwithstanding the foregoing, GMACM shall not be relieved of its
obligations hereunder with respect to the Mortgage Loans and shall be obligated
to the same extent and under the same terms and conditions as if it alone were
servicing and administering the GMACM Mortgage Loans. GMACM shall be entitled to
enter into an agreement with a subservicer for indemnification of GMACM by the
subservicer and nothing contained in this Agreement shall be deemed to limit or
modify such indemnification.

         Any subservicing agreement and any other transactions or services
relating to the GMACM Mortgage Loans involving a subservicer shall be deemed to
be between such subservicer and GMACM alone, and the Trustee shall not have any
obligations, duties or liabilities with respect to such subservicer including
any obligation, duty or liability of the Trustee to pay such subservicer's fees
and expenses or any differential in the amount of the servicing fee paid
hereunder and the amount necessary to induce any successor servicer to act as
successor servicer under this Agreement and the transactions provided for in
this Agreement. For purposes of remittances to the Trustee pursuant to this
Agreement, GMACM shall be deemed to have received a payment on a GMACM Mortgage
Loan when a subservicer has received such payment.

         Section 3.04. DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF GMACM TO BE
HELD FOR TRUSTEE.

         Notwithstanding any other provisions of this Agreement, GMACM shall
transmit to the Trustee as required by this Agreement all documents and
instruments in respect of a GMACM Mortgage Loan coming into the possession of
GMACM from time to time and shall account fully to the Trustee for any funds
received by GMACM or that otherwise are collected by GMACM as Liquidation
Proceeds or Insurance Proceeds in respect of any such Mortgage Loan.

                                      -73-
<PAGE>

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

         Section 3.05. MAINTENANCE OF HAZARD INSURANCE.

         (a) GMACM shall cause to be maintained for each GMACM Mortgage Loan
hazard insurance with extended coverage on the Mortgaged Property in an amount
which is at least equal to the lesser of (i) the Stated Principal Balance of
such GMACM Mortgage Loan and (ii) the amount necessary to fully compensate for
any damage or loss to the improvements that are a part of such property on a
replacement cost basis, in each case in an amount not less than such amount as
is necessary to avoid the application of any coinsurance clause contained in the
related hazard insurance policy. GMACM shall also cause to be maintained hazard
insurance with extended coverage on each REO Property related to a GMACM
Mortgage Loan in an amount which is at least equal to the lesser of (i) the
maximum insurable value of the improvements which are a part of such REO
Property and (ii) the Stated Principal Balance of the related GMACM Mortgage
Loan at the time it became an REO Property. GMACM will comply in the performance
of this Agreement with all reasonable rules and requirements of each insurer
under any such hazard policies. Any amounts collected by GMACM under any such
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or amounts to be released to the
Mortgagor in accordance with the procedures that GMACM would follow in servicing
loans held for its own account, subject to the terms and conditions of the
related Mortgage and Mortgage Note and in accordance with the servicing standard
set forth in Section 3.01) shall be deposited in the related Custodial Account
maintained by GMACM, subject to withdrawal pursuant to Section 4.02. Any cost
incurred by GMACM in maintaining any such insurance shall not, for the purpose
of calculating distributions to Certificateholders, be added to the Stated
Principal Balance of the related GMACM Mortgage Loan, notwithstanding that the
terms of such GMACM Mortgage Loan so permit. It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
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 or REO Property relating to a GMACM Mortgage Loan is at any time in an
area identified in the Federal Register by the Federal Emergency Management
Agency as having special flood hazards and flood insurance has been made
available, GMACM shall cause to be maintained a flood insurance policy in
respect thereof. Such flood insurance shall be in an amount equal to the lesser
of (i) the

                                      -74-
<PAGE>

Stated Principal Balance of the related GMACM Mortgage Loan and (ii) the maximum
amount of such insurance available for the related Mortgaged Property under the
national flood insurance program (assuming that the area in which such Mortgaged
Property is located is participating in such program).

         In the event that GMACM shall obtain and maintain a blanket policy with
an insurer having a General Policy Rating of B:VI or better in Best's Key Rating
Guide (or such other rating that is comparable to such rating) insuring against
hazard losses on all of the GMACM Mortgage Loans, it shall conclusively be
deemed to have satisfied its obligations as set forth in the first two sentences
of this Section 3.05, it being understood and agreed that such policy may
contain a deductible clause, in which case GMACM shall, in the event that there
shall not have been maintained on the related Mortgaged Property or REO Property
a policy complying with the first two sentences of this Section 3.05, and there
shall have been one or more losses which would have been covered by such policy,
deposit to the related Custodial Account maintained by GMACM from its own funds
the amount not otherwise payable under the blanket policy because of such
deductible clause. In connection with its activities as administrator and
servicer of the Mortgage Loans, GMACM agrees to prepare and present, on behalf
of itself, the Trustee and Certificateholders, claims under any such blanket
policy in a timely fashion in accordance with the terms of such policy.

         (b) GMACM shall keep in force during the term of this Agreement a
policy or policies of insurance covering errors and omissions for failure in the
performance of GMACM's obligations under this Agreement, which policy or
policies shall be in such form and amount that would meet the requirements of
Fannie Mae or Freddie Mac if it were the purchaser of the related GMACM Mortgage
Loans, unless GMACM has obtained a waiver of such requirements from Fannie Mae
or Freddie Mac. GMACM shall provide the Trustee, upon request, with copies of
such insurance policies and fidelity bond. GMACM shall also maintain a fidelity
bond in the form and amount that would meet the requirements of Fannie Mae or
Freddie Mac, unless GMACM has obtained a waiver of such requirements from Fannie
Mae or Freddie Mac. GMACM shall be deemed to have complied with this provision
if an Affiliate of GMACM 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 GMACM. Any such errors and omissions
policy and fidelity bond shall by its terms not be cancelable without thirty
days' prior written notice to the Trustee. GMACM shall also cause its
subservicers to maintain a policy of insurance covering errors and omissions and
a fidelity bond which would meet such requirements.

         Section 3.06. PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS.

         GMACM shall prepare and present on behalf of the Trustee and the
Certificateholders all claims under the Insurance Policies and take such actions
(including the negotiation, settlement, compromise or enforcement of the
insured's claim) as shall be necessary to realize recovery under such Insurance
Policies. Any proceeds disbursed to GMACM in respect of such Insurance Policies
shall, within two Business Days of its receipt, be deposited in the related
Custodial Account maintained by GMACM upon receipt, except that any amounts
realized that are to be applied to the repair or restoration of the related
Mortgaged Property as a condition precedent to

                                      -75-
<PAGE>

the presentation of claims on the related GMACM Mortgage Loan to the insurer
under any applicable Insurance Policy need not be so deposited (or remitted).

         Section 3.07. MAINTENANCE OF INSURANCE POLICIES.

         GMACM shall not take any action that would result in noncoverage under
any applicable Insurance Policy of any loss which, but for the actions of GMACM
would have been covered thereunder. GMACM shall use its best efforts to keep in
force and effect (to the extent that the related Mortgage Loan requires the
Mortgagor to maintain such insurance), any applicable Insurance Policy. GMACM
shall not cancel or refuse to renew any Insurance Policy that is in effect at
the date of the initial issuance of the Mortgage Note and is required to be kept
in force hereunder.

         Section 3.08. RESERVED.

         Section 3.09. REALIZATION UPON DEFAULTED GMACM MORTGAGE LOANS;
DETERMINATION OF EXCESS LIQUIDATION PROCEEDS AND REALIZED LOSSES; REPURCHASES OF
CERTAIN GMACM MORTGAGE LOANS.

         (a) GMACM shall use reasonable efforts to foreclose upon or otherwise
comparably convert the ownership of properties securing such of the GMACM
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, GMACM 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 that
GMACM shall not be required to expend its own funds in connection with any
foreclosure or towards the restoration of any property unless it shall determine
(i) that such restoration and/or foreclosure will increase the proceeds of
liquidation of the related GMACM 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 related Custodial Account maintained by GMACM pursuant to
Section 4.02). If GMACM reasonably believes that Liquidation Proceeds with
respect to any such GMACM Mortgage Loan would not be increased as a result of
such foreclosure or other action, such GMACM Mortgage Loan will be charged-off
and will become a Liquidated Loan. GMACM will give notice of any such charge-off
to the Trustee. GMACM shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided that such costs and expenses
shall be Servicing Advances and that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 4.02. If GMACM has knowledge that a Mortgaged Property
that GMACM 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 GMACM, GMACM shall, prior to acquiring the
Mortgaged Property, consider such risks and only take action in accordance with
its established environmental review procedures.

         With respect to any REO Property related to a GMACM Mortgage Loan, the
deed or certificate of sale shall be taken in the name of the Trustee for the
benefit of the Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's

                                      -76-
<PAGE>

name shall be placed on the title to such REO Property solely as the Trustee
hereunder and not in its individual capacity. GMACM shall ensure that the title
to such REO Property references this Agreement and the Trustee's capacity
hereunder. Pursuant to its efforts to sell such REO Property, GMACM shall either
itself or through an agent selected by GMACM 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 GMACM deems to be in the best interest of GMACM and the
Certificateholders for the period prior to the sale of such REO Property. GMACM
shall prepare for and deliver to the Trustee 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 Trustee 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 Custodial
Account maintained by GMACM no later than the close of business on each
Determination Date. GMACM shall perform the tax reporting and withholding
related to foreclosures, abandonments and cancellation of indebtedness income as
specified by Sections 6050H, 6050J and 6050P of the Code by preparing and filing
such tax and information returns, as may be required.

         In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
GMACM Mortgage Loan, GMACM shall dispose of such Mortgaged Property prior to
three years after its acquisition by the Trust Fund or, at the expense of the
Trust Fund, request from the Internal Revenue Service 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. The Trustee shall be supplied with an Opinion of
Counsel (such opinion not to be an expense of the Trustee or the Trust Fund) to
the effect that the holding by the Trust Fund of such Mortgaged Property
subsequent to such three-year period will not result in the imposition of taxes
on "prohibited transactions" of REMIC I, REMIC II, REMIC III or REMIC IV as
defined in section 860F of the Code or cause either REMIC I, REMIC II, REMIC III
or REMIC IV to fail to qualify as a REMIC at any time that any Certificates are
outstanding, in which case the Trust Fund may continue to hold such Mortgaged
Property (subject to any conditions contained in such Opinion of Counsel).
Notwithstanding any other provision of this Agreement, no Mortgaged Property
acquired by the Trust Fund shall be rented (or allowed to continue to be rented)
or otherwise used for the production of income by or on behalf of the Trust Fund
in such a manner or pursuant to any terms that would (i) cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
section 860G(a)(8) of the Code or (ii) subject any of REMIC I, REMIC II, REMIC
III or REMIC IV to the imposition of any federal, state or local income taxes on
the income earned from such Mortgaged Property under section 860G(c) of the Code
or otherwise, unless GMACM has agreed to indemnify and hold harmless the Trust
Fund with respect to the imposition of any such taxes.

         The decision of GMACM to foreclose on a defaulted GMACM Mortgage Loan
shall be subject to a determination by GMACM 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

                                      -77-
<PAGE>

reimbursement to GMACM for expenses incurred (including any property or other
taxes) in connection with such management and net of unreimbursed Servicing
Fees, Advances, Servicing Advances and any management fee paid or to be paid
with respect to the management of such Mortgaged Property, shall be applied to
the payment of principal of, and interest on, the defaulted GMACM Mortgage Loans
(with interest accruing as though such GMACM Mortgage Loans were still current)
and all such income shall be deemed, for all purposes in the Agreement, to be
payments on account of principal and interest on the related Mortgage Notes and
shall be deposited into the related Custodial Account. To the extent the income
received during a Prepayment Period is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Rate on the
related GMACM 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 GMACM Mortgage Loan,
net of any payment to GMACM as provided above, shall be deposited in the related
Custodial Account maintained by GMACM on the next succeeding Determination Date
following receipt thereof for distribution on the related Distribution Date,
except that any Excess Liquidation Proceeds shall be retained by GMACM as
additional servicing compensation.

         The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds or any income from an REO
Property, shall be applied in the following order of priority: first, to
reimburse GMACM for any related unreimbursed Servicing Advances and Servicing
Fees, pursuant to Section 4.02 or this Section 3.09; second, to reimburse GMACM
for any unreimbursed Advances, pursuant to Section 4.02 or this Section 3.09;
third, to accrued and unpaid interest (to the extent no Advance has been made
for such amount) on the GMACM Mortgage Loan or related REO Property, at the Net
Mortgage Rate to the first day of the month in which such amounts are required
to be distributed; and fourth, as a recovery of principal of the GMACM Mortgage
Loan.

                  (b) On each Determination Date, GMACM shall determine the
respective aggregate amounts of Excess Liquidation Proceeds and Realized Losses,
if any, with respect to any GMACM Mortgage Loan for the related Prepayment
Period.

                  (c) GMACM has no intent to foreclose on any GMACM Mortgage
Loan based on the delinquency characteristics as of the Closing Date; provided,
however, that the foregoing does not prevent GMACM from initiating foreclosure
proceedings on any date hereafter if the facts and circumstances of such GMACM
Mortgage Loans including delinquency characteristics in GMACM's discretion so
warrant such action.

         Section 3.10. SERVICING COMPENSATION.

         As compensation for its activities hereunder, GMACM shall be entitled
to retain or withdraw from its Custodial Accounts out of each payment of
interest on each GMACM Mortgage Loan included in the Trust Fund an amount equal
to the Servicing Fee. In addition, GMACM shall be entitled to recover unpaid
Servicing Fees out of Liquidation Proceeds, Insurance Proceeds or condemnation
proceeds to the extent permitted by Section 4.02.

                                      -78-
<PAGE>

         Additional servicing compensation with respect to GMACM Mortgage Loans
in the form of any Excess Liquidation Proceeds, assumption fees, late payment
charges, insufficient funds charges and ancillary income to the extent such fees
or charges are received by GMACM, all income and gain net of any losses realized
from Permitted Investments with respect to funds in or credited to the Custodial
Account maintained by GMACM shall be retained by GMACM to the extent not
required to be deposited in the related Custodial Account pursuant to Section
4.02. GMACM 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 3.05 and maintenance of the other forms
of insurance coverage required by Section 3.07) and shall not be entitled to
reimbursement therefor except as specifically provided in Section 4.02.

         Section 3.11. REO PROPERTY.

                  (a) In the event the Trust Fund acquires ownership of any REO
Property in respect of any related GMACM Mortgage Loan, the deed or certificate
of sale shall be issued to the Trustee, or to its nominee, on behalf of the
related Certificateholders. GMACM shall sell any REO Property as expeditiously
as possible and in accordance with the provisions of this Agreement. Pursuant to
its efforts to sell such REO Property, GMACM shall protect and conserve such REO
Property in the manner and to the extent required herein, in accordance with the
REMIC Provisions.

                  (b) GMACM shall deposit all funds collected and received in
connection with the operation of any REO Property into the related Custodial
Account maintained by GMACM.

                  (c) GMACM, upon the final disposition of any REO Property,
shall be entitled to reimbursement for any related unreimbursed Advances,
unreimbursed Servicing Advances or Servicing Fees from Liquidation Proceeds
received in connection with the final disposition of such REO Property;
provided, that any such unreimbursed Advances or Servicing Fees as well as any
unpaid Servicing Fees may be reimbursed or paid, as the case may be, prior to
final disposition, out of any net rental income or other net amounts derived
from such REO Property.

         Section 3.12. LIQUIDATION REPORTS.

         Upon the foreclosure of any Mortgaged Property or the acquisition
thereof by the Trust Fund pursuant to a deed-in-lieu of foreclosure, GMACM shall
submit a liquidation report to the Trustee containing such information as shall
be mutually acceptable to GMACM and the Trustee with respect to such Mortgaged
Property.

         Section 3.13. ANNUAL CERTIFICATE AS TO COMPLIANCE.

                  (a) GMACM shall deliver to the Depositor and the Trustee not
later than March 15th of each year commencing in 2006 (or, in each case, if such
day is not a Business Day, the immediately preceding Business Day), a
certificate of a Authorized Servicer Representative stating, as to each
signatory thereof, that (i) a review of the activities of GMACM during the
preceding calendar year and of performance under this Agreement has been made
under such

                                      -79-
<PAGE>

officers' supervision, and (ii) to the best of such officers' knowledge, based
on such review, GMACM has fulfilled all of its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officers and the
nature and status thereof except for such defaults as such officer in its good
faith judgment believe to be immaterial.

                  (b) (i) GMACM shall deliver to the Depositor and the Trustee,
on or before March 15th of each year commencing in 2006, a certification
containing the information set forth in Exhibit L. Such certification shall be
signed by the senior officer in charge of servicing of GMACM. In addition, GMACM
shall provide such other information with respect to the GMACM Mortgage Loans
and the servicing and administration thereof within the control of GMACM which
shall be required to enable the Depositor and the Trustee to comply with the
reporting requirements of the Securities and Exchange Act of 1934, as amended
(the "Exchange Act").

                           (ii) GMACM shall indemnify and hold harmless the
Depositor, the Trustee and their respective officers, directors, agents and
affiliates from and against any losses, damages, penalties, fines, forfeitures,
reasonable legal fees and related costs, judgments and other costs and expenses
to the extent arising out of or based upon a breach by GMACM or any of its
officers, directors, agents or affiliates of its obligations under this Section
3.13(b), or a breach in any of the representations in the certification
delivered pursuant to clause (b)(i) above, or GMACM's gross negligence, bad
faith or willful misconduct in connection therewith. If the indemnification
provided for herein is unavailable to the Depositor and the Trustee as a result
of a court of law or other administrative or regulatory body with authority
holding such indemnification void on the basis of public policy or similar
reason or insufficient to hold harmless the Depositor or the Trustee, then GMACM
agrees that it shall contribute to the amount paid or payable by the Depositor
and the Trustee as a result of the losses, claims, damages or liabilities of the
Depositor or the Trustee in such proportion as is appropriate to reflect the
relative fault of the Trustee or the Depositor on the one hand and GMACM on the
other in connection with a breach of GMACM's obligations under this Section
3.13(b) or GMACM's gross negligence, bad faith or willful misconduct in
connection therewith or a breach of any of the representations in the
certification delivered pursuant to clause (b)(i) above with respect to the
matters covered by this Section 3.13(b)(ii).

         Section 3.14. ANNUAL INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS'
SERVICING REPORT.

         Not later than March 15th of each year, commencing in 2006, GMACM, at
its expense, shall cause a nationally recognized firm of independent certified
public accountants to furnish to GMACM a report stating that (i) it has obtained
a letter of representation regarding certain matters from the management of
GMACM which includes an assertion that GMACM has complied with certain minimum
residential mortgage loan servicing standards, identified in the Uniform Single
Attestation Program for Mortgage Bankers established by the Mortgage Bankers
Association of America, with respect to the servicing of residential mortgage
loans during the most recently completed fiscal or calendar year and (ii) on the
basis of an examination conducted by such firm in accordance with standards
established by the American Institute of Certified Public Accountants, such
representation is fairly stated in all material respects, subject to such

                                      -80-
<PAGE>

exceptions and other qualifications that may be appropriate. In rendering its
report such firm may rely, as to matters relating to the direct servicing of
residential mortgage loans by subservicers, upon comparable reports of firms of
independent certified public accountants rendered on the basis of examinations
conducted in accordance with the same standards (rendered within one year of
such report) with respect to those subservicers. Promptly upon receipt of such
report, GMACM shall furnish a copy of such report to the Depositor, the Trustee
and each Rating Agency. Copies of such statement shall be provided by the
Trustee to any Certificateholder upon request at GMACM's expense, provided that
such statement is delivered by GMACM to the Trustee.

         Section 3.15. BOOKS AND RECORDS.

         GMACM shall be responsible for maintaining, and shall maintain, a
complete set of books and records for the GMACM Mortgage Loans which shall be
appropriately identified in GMACM's computer system to clearly reflect the
ownership of the GMACM Mortgage Loans by the Trust. In particular, GMACM shall
maintain in its possession, available for inspection by the Trustee and shall
deliver to the Trustee upon reasonable prior request and during normal business
hours, evidence of compliance with all federal, state and local laws, rules and
regulations. To the extent that original documents are not required for purposes
of realization of Liquidation Proceeds or Insurance Proceeds, documents
maintained by GMACM may be in the form of microfilm or microfiche or such other
reliable means of recreating original documents, including, but not limited to,
optical imagery techniques so long as GMACM complies with the requirements of
Accepted Servicing Practices.

         GMACM shall maintain with respect to each GMACM Mortgage Loan and shall
upon reasonable prior request and during normal business hours make available
for inspection by the Trustee the related servicing file during the time such
GMACM Mortgage Loan is subject to this Agreement and thereafter in accordance
with applicable law.

         Section 3.16. THE TRUSTEE.

         The Trustee shall furnish the Servicers with any powers of attorney and
other documents prepared and submitted by the Servicers to the Trustee in a form
as mutually agreed upon and necessary or appropriate to enable the Servicers to
service and administer the related Mortgage Loans and REO Properties.

         The Trustee shall provide access to the records and documentation in
possession of the Trustee regarding the related Mortgage Loans and REO Property
and the 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 Trustee; provided, however, that, unless otherwise required by
law, the Trustee shall not 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 Trustee 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 Trustee's actual costs.

                                      -81-
<PAGE>

         The Trustee shall execute and deliver as directed in writing by the
Servicers any court pleadings, requests for trustee's sale or other documents
necessary or desirable to (i) the foreclosure or trustee's sale with respect to
a Mortgaged Property; (ii) any legal action brought to obtain judgment against
any Mortgagor on the Mortgage Note or Security Instrument; (iii) obtain a
deficiency judgment against the Mortgagor; or (iv) enforce any other rights or
remedies provided by the Mortgage Note or Security Instrument or otherwise
available at law or equity.

         Section 3.17. REMIC-RELATED COVENANTS.

         For as long as each REMIC shall exist, the Trustee shall act in
accordance herewith to treat each REMIC as a REMIC, and the Trustee shall comply
with any directions of the Seller or the related Servicer regarding such
treatment. In particular, the Trustee shall not (a) knowingly sell or permit the
sale of all or any portion of the Mortgage Loans or of any investment of
deposits in an Account unless such sale is as a result of a repurchase of the
Mortgage Loans pursuant to this Agreement or the Trustee has received a REMIC
Opinion prepared at the expense of the Trust Fund; and (b) other than with
respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, accept any contribution to any
REMIC after the Startup Day without receipt of a REMIC Opinion.

         Section 3.18. REIMBURSEMENT OF COSTS AND EXPENSES.

                  (a) To the extent that the costs and expenses of the Trustee
related to any termination of a Servicer, appointment of a Successor Servicer or
the transfer and assumption of servicing by the Trustee with respect to this
Agreement, the M&T Servicing Agreement or the GreenPoint Servicing Agreement
(including, without limitation, (i) all legal costs and expenses and all due
diligence costs and expenses associated with an evaluation of the potential
termination of the related Servicer as a result of an event of default by such
Person and (ii) all costs and expenses associated with the complete transfer of
servicing, including all servicing files and all servicing data and the
completion, correction or manipulation of such servicing data as may be required
by the Successor Servicer to correct any errors or insufficiencies in the
servicing data or otherwise to enable the successor servicer to service the
related Mortgage Loans in accordance with this Agreement, the M&T Servicing
Agreement or the GreenPoint Servicing Agreement) are not fully and timely
reimbursed by the related Servicer, the Trustee shall be entitled to
reimbursement of such costs and expenses from the related Distribution Account.

                  (b) If the Trustee acts as a Successor Servicer to a Servicer,
it will not assume liability for the representations and warranties of GMACM
contained herein, M&T under the M&T Servicing Agreement or GreenPoint under the
GreenPoint Servicing Agreement.

         Section 3.19. RELEASE OF MORTGAGE FILES.

                  (a) Upon becoming aware of the payment in full of any GMACM
Mortgage Loan, or the receipt by GMACM of a notification that payment in full
has been escrowed in a manner customary for such purposes for payment to
Certificateholders on the next Distribution Date, GMACM will promptly furnish to
the Trustee and the Custodian, on behalf of the Trustee, two copies of a request
for release substantially in the form attached to the Custodial Agreement

                                      -82-
<PAGE>

signed by a Authorized Servicer Representative or in a mutually agreeable
electronic format which will, in lieu of a signature on its face, originate from
a Authorized Servicer Representative (which certification shall include a
statement to the effect that all amounts received in connection with such
payment that are required to be deposited in the Custodial Account maintained by
GMACM pursuant to Article V have been or will be so deposited) and shall request
that the Custodian, on behalf of the Trustee, deliver to GMACM the related
Mortgage File. Within five (5) Business Days of receipt of such certification
and request, the Custodian, on behalf of the Trustee, shall release the related
Mortgage File to GMACM and the Trustee and Custodian shall have no further
responsibility with regard to such Mortgage File. Upon any such payment in full,
GMACM is authorized, to give, as agent for the Trustee, as the mortgagee under
the Mortgage that secured the related GMACM Mortgage Loan, an instrument of
satisfaction (or assignment of mortgage without recourse) regarding the
Mortgaged Property subject to the Mortgage, which instrument of satisfaction or
assignment, as the case may be, shall be delivered to the Person or Persons
entitled thereto against receipt therefor of such payment, it being understood
and agreed that no expenses incurred in connection with such instrument of
satisfaction or assignment, as the case may be, shall be chargeable to the
Custodial Account maintained by GMACM.

         (b) From time to time and as appropriate for the servicing or
foreclosure of any GMACM Mortgage Loan and in accordance with this Agreement,
the Trustee shall execute such documents as shall be prepared and furnished to
the Trustee by GMACM (in form reasonably acceptable to the Trustee) and as are
necessary to the prosecution of any such proceedings. The Custodian, on behalf
of the Trustee, shall, upon the written request of GMACM, and delivery to the
Custodian, on behalf of the Trustee, of two copies of a request for release
signed by a Authorized Servicer Representative substantially in the form
attached to the Custodial Agreement (or in a mutually agreeable electronic
format which will, in lieu of a signature on its face, originate from a
Authorized Servicer Representative), release the related Mortgage File held in
its possession or control to GMACM. Such request for release shall obligate
GMACM to return the Mortgage File to the Custodian on behalf of the Trustee,
when the need therefor by such Person no longer exists unless the GMACM Mortgage
Loan shall be liquidated, in which case, upon receipt of a certificate of a
Authorized Servicer Representative similar to that hereinabove specified, the
Mortgage File shall be released by the Custodian, on behalf of the Trustee, to
GMACM.

         Section 3.20. DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF GMACM TO BE
HELD FOR TRUSTEE.

                  (a) GMACM (to the extent required by this Agreement) shall
transmit to the Trustee or to Custodian such documents and instruments coming
into the possession of such Person from time to time as are required by the
terms hereof to be delivered to the Trustee or the Custodian. Any funds received
by GMACM in respect of any Mortgage Loan or which otherwise are collected by
GMACM as Liquidation Proceeds or Insurance Proceeds in respect of any GMACM
Mortgage Loan shall be held for the benefit of the Trustee and the
Certificateholders subject to the right of GMACM to retain its Servicing Fee and
other amounts as provided in this Agreement.

                                      -83-
<PAGE>

         Section 3.21. POSSESSION OF CERTAIN INSURANCE POLICIES AND DOCUMENTS.

         GMACM shall retain possession and custody of the originals (to the
extent available) of any 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, the
Trustee (or the Custodian, as directed by the Trustee) shall retain possession
and custody of each Mortgage File in accordance with and subject to the terms
and conditions of this Agreement.

         Section 3.22. SEC FILINGS.

                  (a) The Depositor shall prepare and file or caused to be
prepared and filed the initial Form 8-K. Within 15 days after each Distribution
Date, the Trustee shall, in accordance with industry standards, file with the
Commission via the Electronic Data Gathering and Retrieval System ("EDGAR"), a

Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2005, the Trustee shall, in accordance with industry standards, file
a Form 15 Suspension Notice with respect to the Trust Fund. Prior to March 30,
2006 and annually thereafter, if required, the Trustee shall, subject to
subsection (d) below, file a Form 10-K, in substance conforming to industry
standards, with respect to the Trust Fund. Such Form 10K shall be signed by the
Depositor and shall include, to the extent available, as exhibits (i) each
Servicer's annual statement of compliance described under Section 3.13 hereof,
or under the M&T Servicing Agreement or GreenPoint Servicing Agreement, as
applicable (ii) each Servicer's accountants report described under Section 3.14
or under the M&T Servicing Agreement or GreenPoint Servicing Agreement, as
applicable and (iii) the Form 10-K certification signed by the Depositor. If
items (i), (ii) and (iii) in the preceding sentence are not timely delivered,
the Trustee shall file an amended Form 10-K including such documents as exhibits
reasonably promptly after they are delivered to the Trustee. The Depositor shall
execute and the Trustee shall file each Form 8-K and the Form 15. The Depositor
agrees to promptly furnish to the Trustee, from time to time upon request, such
further information, reports and financial statements within its control related
to this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file a Form 8-K and the Form 15 with the Commission.
The Trustee will reasonably cooperate with the Depositor in connection with any
additional filings with respect to the Trust Fund as the Depositor deems
necessary under the Exchange Act. Copies of all reports filed by the Trustee
under the Exchange Act shall be sent to the Depositor.

                  (b) In connection with the filing of any 10-K hereunder, the
Trustee shall sign a certification (in the form attached hereto as Exhibit M)
for the benefit of the Depositor regarding certain aspects of the Form 10-K
certification signed by the Depositor, provided, however, that the Trustee shall
not be required to undertake an analysis of any accountant's report attached as
an exhibit to the Form 10-K.

                  (c) (i) The Trustee shall indemnify and hold harmless the
Depositor and its officers, directors and Affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and

                                      -84-
<PAGE>

expenses arising out of or based upon a breach of the Trustee's obligations
under this Section 3.22 or the Trustee's gross negligence, bad faith or willful
misconduct in connection therewith.

                           (ii) The Depositor shall indemnify and hold harmless
the Trustee and its officers, directors and Affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach of the obligations of the Depositor under this Section 3.22
or the Depositor's negligence, bad faith or willful misconduct in connection
therewith.

                           (iii) If the indemnification provided for herein is
unavailable or insufficient to hold harmless the Depositor or the Trustee, as
applicable, then the other party, in connection with a breach of its respective
obligations under this Section 3.22 or its respective gross negligence, bad
faith or willful misconduct in connection therewith, agrees that it shall
contribute to the amount paid or payable by the other party as a result of the
losses, claims, damages or liabilities of the other party in such proportion as
is appropriate to reflect the relative fault and the relative benefit of the
Depositor on the one hand and the Trustee on the other.

                  (d) Nothing shall be construed from the foregoing subsections
(a), (b) and (c) to require the Trustee or any officer, director or Affiliate
thereof to sign any Form 10-K or any certification contained therein.
Furthermore, the inability of the Trustee to file a Form 10-K as a result of the
lack of required information as set forth in Section 3.22(a) or required
signatures on such Form 10-K or any certification contained therein shall not be
regarded as a breach by the Trustee of any obligation under this Agreement.

                  (e) Notwithstanding the provisions of Section 11.01, this
Section 3.22 may be amended without the consent of the Certificateholders.

         Section 3.23. UCC.

         The Seller agrees to execute and file continuation statements for any
Uniform Commercial Code financing statements which the Seller has informed the
Trustee were filed on the Closing Date in connection with the Trust. The Seller
shall file any financing statements or amendments and continuation statements
thereto required by any change in the Uniform Commercial Code.

         Section 3.24. OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

         With respect to any Mortgage Loan which is delinquent in payment by 91
days or more or is an REO Property, the Seller shall have the right to purchase
such Mortgage Loan or REO Property from the Trust at a price equal to the
Purchase Price.

         The Seller shall remit to GMACM for deposit in the related Custodial
Account the amount of the Purchase Price for any such GMACM Mortgage Loan
purchased pursuant to this Section 3.24 or remit to the Trustee for deposit in
the related Distribution Account the amount of the Purchase Price for any M&T

                                      -85-
<PAGE>

notification from the GMACM or the Depositor of the deposit of such Purchase
Price in the related Custodial Account, shall execute the assignment of such
Mortgage Loan at the request of the Seller without recourse, representation or
warranty to the Seller which shall succeed to all the Trustee's right, title and
interest in and to such Mortgage Loan, and all security and documents relative
thereto. Such assignment shall be an assignment outright and not for security.
The Seller will thereupon own such Mortgage, and all such security and
documents, free of any further obligation to the Trustee or the
Certificateholders with respect thereto.

         Section 3.25. ENFORCING OBLIGATIONS OF THE SERVICERS.

                  (a) Notwithstanding anything in this Agreement or the Credit
Risk Management Agreements to the contrary, the Trustee shall not have any duty
or obligation to enforce any Credit Risk Management Agreement or to supervise,
monitor or oversee the activities of the Credit Risk Manager or the Servicers
under the Credit Risk Management Agreements or this Agreement with respect to
any action taken or not taken by the related Servicer pursuant to a
recommendation of the Credit Risk Manager or otherwise in connection with
obligations of the Servicer under the related Credit Risk Management Agreement.
To the extent that the costs and expenses of the Trustee related to any
termination of a Servicer, appointment of a Successor Servicer or the transfer
and assumption of servicing by the Trustee with respect to this Agreement
(including, without limitation, (i) all legal costs and expenses and all due
diligence costs and expenses associated with an evaluation of the potential
termination of the related Servicer as a result of an event of default by such
Person and (ii) all costs and expenses associated with the complete transfer of
servicing, including all servicing files and all servicing data and the
completion, correction or manipulation of such servicing data as may be required
by the Successor Servicer to correct any errors or insufficiencies in the
servicing data or otherwise to enable the successor servicer to service the
related Mortgage Loans in accordance with this Agreement, the M&T Servicing
Agreement or the GreenPoint Servicing Agreement, as applicable) are not fully
and timely reimbursed by the related Servicer, the Trustee shall be entitled to
reimbursement of such costs and expenses from the related Distribution Account.

                  (b) If the Trustee acts as a Successor Servicer to a Servicer,
it will not assume liability for the representations and warranties of the
related Servicer contained in this Agreement, the M&T Servicing Agreement or the

                                    ACCOUNTS

         Section 4.01. COLLECTION OF MORTGAGE LOAN PAYMENTS; CUSTODIAL ACCOUNT.

                  (a) GMACM shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the GMACM 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, GMACM may in its
discretion (i) waive any late payment charge and (ii) extend the due dates for
payments due on a Mortgage Note for a GMACM Mortgage Loan for a period not
greater than 180 days; provided, however no such extension shall be materially
adverse to the Certificateholders. In the event of any such arrangement, GMACM
shall make Advances on the GMACM Mortgage Loan during the scheduled period in
accordance with the amortization schedule of such Mortgage Loan without
modification thereof by reason of such arrangements, and shall be entitled to
reimbursement therefor in accordance with Section 5.01. GMACM 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. In addition, if (x) a GMACM Mortgage Loan is in default or
default is imminent or (y) GMACM delivers to the Trustee a REMIC Opinion, GMACM
may, (A) amend the related Mortgage Note to reduce the Mortgage Rate applicable
thereto, provided that such reduced Mortgage Rate shall in no event be lower
than 4.50% with respect to any Mortgage Loan and (B) amend any Mortgage Note for
a GMACM Mortgage Loan to extend the maturity thereof.

                  (b) GMACM shall establish and maintain two segregated
Custodial Accounts (which shall at all times be Eligible Accounts) with a
depository institution in the name of GMACM for the benefit of the Trustee on
behalf of the Certificateholders and designated "Wells Fargo Bank, National
Association, as trustee for registered holders of Nomura Asset Acceptance
Corporation, Mortgage Pass-Through Certificates, Series 2005-AP1, Group I" and
"Wells Fargo Bank, National Association, as trustee for registered holders of
Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series
2005-AP1, Group II." On behalf of the Trust Fund, GMACM shall deposit or cause
to be deposited in the clearing account in which it customarily deposits
payments and collection on mortgage loans in connection with its mortgage loan
servicing activities on a daily basis and in no event more than one Business Day
after GMACM's receipt thereof, and shall thereafter deposit in the related
Custodial Account, in no event more than two Business Days after GMACM's receipt
thereof, except as otherwise specifically provided herein, the following
payments and collections remitted by subservicers or received by it in respect
of the GMACM Mortgage Loans subsequent to the Cut-off Date (other than in
respect of principal and interest due on the GMACM Mortgage Loans on or before
the Cut-off Date) and the following amounts required to be deposited hereunder:

                  (i) all payments on account of principal, including Principal
         Prepayments and Subsequent Recoveries, on the related GMACM Mortgage
         Loans;

                                      -87-
<PAGE>

                  (ii) all payments on account of interest on the related GMACM
         Mortgage Loans net of the related Servicing Fee permitted under Section
         3.10;

                  (iii) all Liquidation Proceeds, Insurance Proceeds and
         condemnation proceeds with respect to the related GMACM Mortgage Loans,
         other than proceeds to be applied to the restoration or repair of the
         related Mortgaged Property or released to the Mortgagor in accordance
         with GMACM's normal servicing procedures;

                  (iv) any amount required to be deposited by GMACM pursuant to
         Section 4.01(c) in connection with any losses on Permitted Investments;

                  (v) any amounts required to be deposited by GMACM pursuant to
         Section 3.05;

                  (vi) any amounts paid by an Advance Financing Person in
         respect of Advances or Servicing Advances;

                  (vii) any Prepayment Charges collected by GMACM in connection
         with the Principal Prepayment of any of the GMACM Mortgage Loans and
         any Servicer Prepayment Charge Payment Amounts;

                  (viii) the related Repurchase Price with respect to any GMACM
         Mortgage Loan purchased by the Seller pursuant to Section 2.02 or
         Section 2.03, any amounts which are to be treated pursuant to Section
         2.04 of this Agreement as the payment of such a Repurchase Price, and
         the Repurchase Price with respect to any GMACM Mortgage Loan purchased
         by the Depositor pursuant to Section 3.24; and

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

                  The foregoing requirements for deposit by GMACM into the
Custodial Accounts shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of late
payment charges or assumption fees, if collected, need not be deposited by
GMACM. In the event that GMACM shall deposit any amount not required to be
deposited and not otherwise subject to withdrawal pursuant to Section 4.02, it
may at any time withdraw or direct the institution maintaining its Custodial
Accounts, to withdraw such amount from such Custodial Accounts, any provision
herein to the contrary notwithstanding. Such withdrawal or direction may be
accomplished by delivering written notice thereof to the institution maintaining
its Custodial Accounts, that describes the amounts deposited in error in the
Custodial Accounts. GMACM shall maintain adequate records with respect to all
withdrawals made pursuant to this Section. All funds deposited in GMACM's
Custodial Accounts shall be held in trust for the related Certificateholders
until withdrawn in accordance with Section 4.02.

                  (c) The institution that maintains the Custodial Accounts with
respect to the GMACM Mortgage Loans, or other authorized entity shall invest the
funds in the Custodial Accounts, in the manner directed by GMACM, in Permitted
Investments which shall mature not later than the next succeeding Remittance
Date and shall not be sold or disposed of prior to its

                                      -88-
<PAGE>

maturity. All such Permitted Investments shall be made in the name of the
Trustee, for the benefit of the related Certificateholders. All income and gain
net of any losses realized from any such investment shall be for the benefit of
GMACM as servicing compensation and shall be remitted to it monthly as provided
herein. The amount of any losses incurred in GMACM's Custodial Accounts in
respect of any such investments shall be deposited by GMACM into such Custodial
Accounts, out of its own funds.

                  (d) GMACM shall give at least 30 days advance notice to the
Trustee, the Seller, each Rating Agency and the Depositor of any proposed change
of location of the Custodial Accounts relating to the GMACM Mortgage Loans prior
to any change thereof.

         Section 4.02. PERMITTED WITHDRAWALS FROM THE CUSTODIAL ACCOUNTS.

                  (a) GMACM may from time to time make withdrawals from the
related Custodial Account relating to the GMACM Mortgage Loans for the following
purposes:

                  (i) to pay itself (to the extent not previously paid to or
         withheld by GMACM), as servicing compensation in accordance with
         Section 3.10, that portion of any payment of interest that equals the
         Servicing Fee for the period with respect to which such interest
         payment was made, and, as additional servicing compensation, those
         other amounts set forth in Section 3.10;

                  (ii) to reimburse GMACM or an Advance Financing Person for (A)
         any unreimbursed Advances to the extent of amounts received which
         represent late recoveries of payments of principal and/or interest (net
         of the related Servicing Fees), Liquidation Proceeds and Insurance
         Proceeds on the GMACM Mortgage Loans with respect to which such
         Advances were made in accordance with the provisions of Section 5.01;
         and (B) any unreimbursed Advances with respect to the final liquidation
         of a GMACM Mortgage Loan that are Nonrecoverable Advances, but only to
         the extent that late recoveries of payments of principal and/or
         interest, Liquidation Proceeds and Insurance Proceeds received with
         respect to such GMACM Mortgage Loan are insufficient to reimburse GMACM
         or an Advance Financing Person for such unreimbursed Advances or (C)
         subject to Section 4.02(b), any unreimbursed Advances to the extent of
         Amounts Held For Future Distribution funds held in the Custodial
         Accounts relating to the GMACM Mortgage Loans that were not included in
         the Available Distribution Amount for the preceding Distribution Date;

                  (iii) to reimburse GMACM or an Advance Financing Person for
         any Nonrecoverable Advances;

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

                  (v) to pay GMACM any unpaid Servicing Fees and to reimburse it
         or any Advance Financing Person for any unreimbursed Servicing
         Advances, provided, however, that GMACM's or such Advance Financing
         Person's right to reimbursement for Servicing Advances pursuant to this
         subclause (v) with respect to any GMACM

                                      -89-
<PAGE>

         Mortgage Loan shall be limited to amounts received on particular GMACM
         Mortgage Loan(s) (including, for this purpose, late recoveries of
         payments of principal and/or interest, Liquidation Proceeds, Insurance
         Proceeds, condemnation proceeds and purchase and repurchase proceeds)
         that represent late recoveries of the payments for which such Servicing
         Advances were made;

                  (vi) to pay to the Seller or the Depositor with respect to
         each GMACM Mortgage Loan or property acquired in respect thereof that
         has been purchased pursuant to Section 2.02, 2.03 or 3.24, all amounts
         received thereon and not taken into account in determining the related
         Stated Principal Balance of such repurchased GMACM Mortgage Loan;

                  (vii) to pay any expenses recoverable by GMACM pursuant to
         Section 7.04;

                  (viii) to withdraw any amount deposited in the Custodial
         Accounts relating to the GMACM Mortgage Loans and not required to be
         deposited therein; and

                  (ix) to clear and terminate the related Custodial Account
         relating to the GMACM Mortgage Loans upon the exercise of the Optional
         Termination pursuant to Section 10.01 hereof.

         In addition, no later than 3:00 p.m. Eastern time on the Remittance
Date, GMACM shall withdraw from the related Custodial Account and remit to the
Trustee (a) all amounts deposited in the related Custodial Account as of the
close of business on the last day of the related Due Period (net of charges
against or withdrawals from the related Custodial Account pursuant to this
Section 4.02), plus (b) all Advances, if any, which GMACM is obligated to make
pursuant to Section 5.01, minus (c) any amounts attributable to Principal
Prepayments, Liquidation Proceeds, Insurance Proceeds or condemnation proceeds
received after the applicable Prepayment Period, which amounts shall be remitted
on the following Remittance Date, together with any Compensating Interest
required to be deposited in the related Custodial Account in connection with
such Principal Prepayment in accordance with Section 5.02, and minus (d) any
amounts attributable to Scheduled Payments collected but due on a Due Date or
Due Dates subsequent to the first day of the month in which such Remittance Date
occurs, which amounts shall be remitted on the Remittance Date next succeeding
the Due Date related to such Scheduled Payment.

         With respect to any remittance received by the Trustee after the
Business Day on which such payment was due, the Trustee shall send written
notice thereof to GMACM. GMACM shall pay to the Trustee interest on any such
late payment by GMACM at an annual rate equal to Prime Rate (as defined in The
Wall Street Journal) plus one percentage point, but in no event greater than the
maximum amount permitted by applicable law. Such interest shall be paid by GMACM
to the Trustee on the date such late payment is made and shall cover the period
commencing with the day following the Business Day on which such payment was due
and ending with the Business Day on which such payment is made, both inclusive.
The payment by GMACM of any such interest, or the failure of the Trustee to
notify GMACM of such interest, shall not be deemed an extension of time for
payment or a waiver of any Servicer Default by GMACM.

                                      -90-
<PAGE>

         GMACM shall keep and maintain separate accounting, on a Mortgage Loan
by Mortgage Loan basis, for the purpose of justifying any withdrawal from the
Custodial Account pursuant to subclauses (i), (ii), (iv), (v) and (vi) above.
Prior to making any withdrawal from the Custodial Account relating to the GMACM
Mortgage Loans pursuant to subclause (iii), GMACM shall deliver to the Trustee
an Officer's Certificate of a Authorized Servicer Representative indicating the
amount of any previous Advance or Servicing Advance determined by GMACM to be a
Nonrecoverable Advance and identifying the related GMACM Mortgage Loan(s), and
their respective portions of such Nonrecoverable Advance.

                  (b) Notwithstanding the foregoing, any Amounts Held For Future
Distribution withdrawn by GMACM as permitted in Section 4.02(a)(ii) in
reimbursement of Advances previously made by GMACM shall be appropriately
reflected in GMACM's records and replaced by GMACM by deposit in the related
Custodial Account, no later than the close of business on any future Remittance
Date on which the funds on deposit in the related Custodial Account shall be
less than the amount required to be remitted to the Trust on such Remittance
Date; provided, however that if the rating of GMACM (including any Successor
Servicer) is less than "BBB", GMACM shall be required to replace such funds by
deposit to the Distribution Account, no later than the close of business on the
Remittance Date immediately following the Due Period or Prepayment Period for
which such amounts relate.

         Section 4.03. REPORTS TO TRUSTEE.

         On or before the tenth calendar day of each month, GMACM shall furnish
to the Trustee electronically in a format reasonably acceptable to the Trustee
loan accounting reports in the investor's assigned loan number order to document
the payment activity on each GMACM Mortgage Loan on an individual mortgage loan
basis. With respect to each month, such loan accounting reports shall contain
the following and any other information reasonably requested by the Trustee to
prepare the Monthly Statements; provided that such information requested by the
Trustee is reasonably available to GMACM and, provided further, that GMACM shall
have no obligation to provide such additional reports or other information
unless GMACM can do so with no more than nominal additional expense:

                  (i) With respect to each Scheduled Payment (on both an actual
         and scheduled basis with respect to mortgage loan balances and on an
         actual basis with respect to paid-through dates), the amount of such
         remittance allocable to principal (including a separate breakdown of
         any Principal Prepayment, including the amount of any Prepayment
         Interest Shortfall);

                  (ii) with respect to each Monthly Payment, the amount of such
         remittance allocable to scheduled interest;

                  (iii) the amount of any Prepayment Charges collected by GMACM;
                  (iv) the amount of servicing compensation received by GMACM
         during the prior calendar month;

                  (v) the aggregate Stated Principal Balance of the GMACM
         Mortgage Loans;

                                      -91-
<PAGE>

                  (vi) the aggregate amount of Advances made by GMACM pursuant
         to Section 5.01;

                  (vii) the aggregate of any expenses reimbursed to GMACM during
         the prior calendar month pursuant to Section 4.02; and

                  (viii) the number and aggregate outstanding principal balances
         of GMACM Mortgage Loans (a) delinquent (1) 30 to 59 days, (2) 60 to 89
         days, (3) 90 days or more; (b) as to which foreclosure has commenced;
         and (c) as to which REO Property has been acquired.

         Section 4.04. COLLECTION OF TAXES; ASSESSMENTS AND SIMILAR ITEMS;
ESCROW ACCOUNTS.

         To the extent required by the Mortgage Note related to a GMACM Mortgage
Loan, GMACM 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 GMACM) for the payment of taxes, assessments, hazard insurance
premiums or comparable items for the account of the Mortgagors. Nothing herein
shall require GMACM to compel a Mortgagor to establish an Escrow Account in
violation of applicable law.

         Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
GMACM out of related collections for any payments made with respect to each
GMACM Mortgage Loan pursuant to Section 3.01 (with respect to taxes and
assessments and insurance premiums) and Section 3.05 (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 such Mortgagors on balances in the Escrow Account,
to remove amounts deposited in error or to clear and terminate the Escrow
Account at the termination of this Agreement in accordance with Section 10.01
thereof. The Escrow Account shall not be a part of the Trust Fund.

         Section 4.05. M&T CUSTODIAL ACCOUNTS AND GREENPOINT CUSTODIAL ACCOUNTS.

                  (a) The Custodial Accounts established by M&T under the M&T
Servicing Agreement and GreenPoint under the GreenPoint Servicing Agreement
shall, to the extent provided in the M&T Servicing Agreement or GreenPoint
Servicing Agreement, as applicable, be an Eligible Account and segregated on the

on a Mortgage Loan by Mortgage Loan basis, for the purpose of accounting for any
reimbursement from the Distribution Accounts pursuant to subclauses (ii) through
(v), inclusive, and (vii) or with respect to any such amounts which would have
been covered by such subclauses had the amounts not been retained by the Trustee
without being deposited in the Distribution Accounts under Section 4.07.

                  (c) On each Distribution Date, the Trustee shall distribute

         Section 4.08. DUTIES OF THE CREDIT RISK MANAGER; TERMINATION.

                  (a) The Depositor appoints The Murrayhill Company as Credit
Risk Manager. For and on behalf of the Depositor, the Credit Risk Manager will
provide reports and recommendations concerning the Mortgage Loans that are past
due, as to which there has been commencement of foreclosure, as to which there
has been forbearance in exercise of remedies which are in default, as to which a
Mortgagor is the subject of bankruptcy, receivership, or an arrangement of
creditors, or as to which have become REO Properties. Such reports and
recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the related Credit Risk Management Agreement and the Credit
Risk Manager shall look solely

                                      -96-
<PAGE>

to the related Servicer for all information and data (including loss and
delinquency information and data) and loan level information and data relating
to the servicing of the related Mortgage Loans. If the Credit Risk Manager is no
longer able to perform its duties hereunder, the Credit Risk Manager may be
terminated by the Depositor at the direction of Certificateholders evidencing
not less than 66 2/3% of the Voting Rights. The Depositor may, at its option,
cause the appointment of a successor Credit Risk Manager. Upon any termination
of the Credit Risk Manager or the appointment of a successor Credit Risk
Manager, the Depositor shall give written notice thereof to the Servicers, the
Trustee, each Rating Agency and the Credit Risk Manager. Notwithstanding the
foregoing, the termination of the Credit Risk Manager pursuant to this Section
4.08(a) shall not become effective until the appointment of a successor Credit
Risk Manager.

                  (b) Within six months of the Closing Date, the Seller may, at
its option, terminate the Credit Risk Manager if, in its reasonable judgment,
(i) the value of the servicing rights with respect to the Mortgage Loans is
adversely affected as a result of the presence of the Credit Risk Manager or
(ii) the presence of the Credit Risk Manager impairs the ability of the Seller
to transfer the servicing rights with respect to the Mortgage Loans as permitted
by this Agreement. Upon the termination of the Credit Risk Manager, the Seller
may, at its option, cause the Depositor to appoint a successor Credit Risk
Manager. Notice of such termination shall be provided by the Seller to the
Rating Agencies, the Trustee, the Depositor, the Servicers and the Credit Risk
Manager. Upon the appointment of a successor Credit Risk Manager, the Depositor
shall provide written notice thereof to each Rating Agency, the Trustee, the
Servicers and the Credit Risk Manager.

                  If the Credit Risk Manager is terminated pursuant to this
Section 4.08(b), the Credit Risk Manager shall only be entitled to a fee equal
to 0.0050% with respect to each Mortgage Loan for the one year period following
such termination. After the expiration of such one year period, the Credit Risk
Manager shall not be entitled to the Credit Risk Management Fee or any portion
thereof with respect to any Mortgage Loan. The exess of the Credit Risk
Management Fee with respect to each Mortgage Loan over the amount payable to the
Credit Risk Manager as described in this paragraph shall be paid to the Holder
of the Class II-C Certificate pursuant to Section 4.07(a)(vii).

         Section 4.09. LIMITATION UPON LIABILITY OF THE CREDIT RISK MANAGER.

         Neither the Credit Risk Manager, nor any of the directors, officers,
employees or agents of the Credit Risk Manager, shall be under any liability to
the Trustee, the Certificateholders or the Depositor for any action taken or for
refraining from the taking of any action in good faith pursuant to this
Agreement, in reliance upon information provided by a Servicer under the related
Credit Risk Management Agreement or of errors in judgment; provided, however,
that this provision shall not protect the Credit Risk Manager or any such person
against liability that would otherwise be imposed by reason of willful
malfeasance, bad faith or gross negligence in its performance of its duties
under this Agreement or any Credit Risk Management Agreement. The Credit Risk
Manager and any director, officer, employee or agent of the Credit Risk Manager
may rely in good faith on any document of any kind prima facie properly executed
and

                                      -97-
<PAGE>

submitted by any Person respecting any matters arising hereunder, and may
rely in good faith upon the accuracy of information furnished by a Servicer
pursuant to the related Credit Risk Management Agreement in the performance of
its duties thereunder and hereunder.

                           ADVANCES AND DISTRIBUTIONS

         Section 5.01. ADVANCES; ADVANCE FACILITY.

                  (a) GMACM shall make an Advance with respect to any GMACM
Mortgage Loan and deposit such Advance in the Distribution Account no later than
3:00 p.m. Eastern time on the Remittance Date in immediately available funds.
M&T shall remit any Advance with respect to a M&T Mortgage Loan as required
under the M&T Servicing Agreement. GreenPoint shall remit any Advance with
respect to a GreenPoint Mortgage Loan as required under the GreenPoint Servicing
Agreement.The related Servicer shall be obligated to make any such Advance only
to the extent that such advance would not be a Nonrecoverable Advance. If the
related Servicer shall have determined that it has made a Nonrecoverable Advance
or that a proposed Advance or a lesser portion of such Advance would constitute
a Nonrecoverable Advance, such Servicer shall deliver (i) to the Trustee for the
benefit of the Certificateholders funds constituting the remaining portion of
such Advance, if applicable, and (ii) to the Depositor, each Rating Agency and
the Trustee an Officer's Certificate setting forth the basis for such
determination.

                  In lieu of making all or a portion of such Advance from its
own funds, GMACM may (i) cause to be made an appropriate entry in its records
relating to the related Custodial Account that any Amounts Held for Future
Distribution has been used by GMACM in discharge of its obligation to make any
such Advance and (ii) transfer such funds from the related Custodial Account to
the related Distribution Account. Any funds so applied and transferred shall be
replaced by GMACM by deposit in the Distribution Account, no later than the
close of business on any future Remittance Date on which the funds on deposit in
the related Custodial Account shall be less than the amount required to be
remitted to the Trustee on such Remittance Date; provided, however that if the
rating of GMACM (including any Successor Servicer) is less than "BBB", GMACM
shall be required to replace such funds by deposit to the Distribution Account,
no later than the close of business on the Remittance Date immediately following
the Due Period or Prepayment Period for which such amounts relate.

                  The related Servicer shall be entitled to be reimbursed from
the related Custodial Account for all Advances of its own funds made pursuant to
this Section or pursuant to the M&T Servicing Agreement or GreenPoint Servicing
Agreement, as applicable, as provided in Section 4.02 or as provided in the M&T
Servicing Agreement or the GreenPoint Servicing Agreement, as applicable. The
obligation to make Advances with respect to any Mortgage Loan shall continue
until such Mortgage Loan is paid in full or the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Trust Fund pursuant to any
applicable provision of this Agreement, except as otherwise provided in this
Section 5.01.

                  Subject to and in accordance with the provisions of Article
VIII hereof, in the event that the related Servicer fails to make such Advance,
then the Trustee, as a Successor Servicer, shall be obligated to make such
Advance only to the extent such Advance, if made,

                                      -99-
<PAGE>

would not constitute a Nonrecoverable Advance, subject to the provisions of
Sections 5.01 and 8.02.

                  (b)(i) GMACM is hereby authorized to enter into a financing or
other facility (any such arrangement, an "Advance Facility"), the documentation
for which complies with Section 5.01(b)(v) below, under which (1) GMACM assigns
or pledges its rights under this Agreement to be reimbursed for any or all
Advances and/or Servicing Advances to (i) a Person, which may be a
special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing Person agrees to fund all the Advances and/or Servicing Advances
required to be made by GMACM pursuant to this Agreement. No consent of the
Trustee, Certificateholders or any other party shall be required before GMACM
may enter into an Advance Facility nor shall the Trustee or the
Certificateholders be a third party beneficiary of any obligation of an Advance
Financing Person to GMACM. Notwithstanding the existence of any Advance Facility
under which an Advance Financing Person agrees to fund Advances and/or Servicing
Advances, (A) GMACM (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 GMACM's
Assignee (as hereinafter defined) shall have any right to proceed against or
otherwise contact any GMACM 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 GMACM Mortgage Loan documents.

                  (ii) If GMACM enters into an Advance Facility, GMACM and the
related Advance Financing Person shall deliver to the Trustee at the address set
forth in Section 11.05 hereof no later than the Remittance Date immediately
following the effective date of such Advance Facility a written notice (an
"Advance Facility Notice"), stating (a) the identity of the Advance Financing
Person and (b) the identity of the Person ("GMACM's Assignee") that will,
subject to Section 5.01(b)(iii) hereof, have the right to make withdrawals from
the related Custodial Account pursuant to Section 4.02 hereof to reimburse
previously unreimbursed Advances and/or Servicing Advances ("Advance
Reimbursement Amounts"). Advance Reimbursement Amounts (i) shall consist solely
of amounts in respect of Advances and/or Servicing Advances for which GMACM
would be permitted to reimburse itself in accordance with Section 4.02 hereof,
assuming GMACM 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 4.02 hereof to the extent permitted under Section 5.01(b)(v) below.

                  (iii) Notwithstanding the existence of an Advance Facility,
GMACM, on behalf of the Advance Financing Person and GMACM's Assignee, shall be
entitled to receive reimbursements of Advances and/or Servicing Advances in
accordance with Section 4.02 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 11.05 hereof. Upon receipt of such

                                     -100-
<PAGE>

written notice, GMACM shall no longer be entitled to receive reimbursement for
any Advance Reimbursement Amounts and GMACM's Assignee shall immediately have
the right to receive from the related Custodial Account all Advance
Reimbursement Amounts. Notwithstanding the foregoing, and for the avoidance of
doubt, (i) GMACM and/or GMACM's Assignee shall only be entitled to reimbursement
of Advance Reimbursement Amounts hereunder from withdrawals from the related
Custodial Account pursuant to Section 4.02 of this Agreement and shall not
otherwise be entitled to make withdrawals or receive amounts that shall be
deposited in the Distribution Account pursuant to Section 4.06 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
GMACM or GMACM's Assignee, as applicable, shall be entitled pursuant to Section
4.02 hereof. An Advance Facility may be terminated by the joint written
direction of GMACM and the related Advance Financing Person. Written notice of
such termination shall be delivered to the Trustee in the manner set forth in
Section 11.05 hereof. None of the Depositor or the Trustee shall, as a result of
the existence of any Advance Facility, have any additional duty or liability
with respect to the calculation or payment of any Advance Reimbursement Amount,
nor, as a result of the existence of any Advance Facility, shall the Depositor
or the Trustee have any additional responsibility to track or monitor the
administration of the Advance Facility or the payment of Advance Reimbursement
Amounts to GMACM's Assignee. GMACM shall indemnify the Depositor, the Trustee,
any successor Servicer and the Trust Fund for any claim, loss, liability or
damage resulting from any claim by the related Advancing Financing Person,
except to the extent that such claim, loss, liability or damage resulted from or
arose out of gross negligence, recklessness or willful misconduct on the part of
the Depositor, the Trustee or any successor Servicer, as the case may be, or
failure by the successor Servicer or the Trustee, as the case may be, to remit
funds as required by this Agreement or the commission of an act or omission to
act by the successor Servicer or the Trustee, as the case may be, and the
passage of any applicable cure or grace period, such that an Event of Default
under this Agreement occurs or such entity is subject to termination for cause
under this Agreement. GMACM shall maintain and provide to any successor Servicer
and, upon request, the Trustee a detailed accounting on a loan-by-loan basis as
to amounts advanced by, pledged or assigned to, and reimbursed to any Advancing
Financing Person. The successor Servicer shall be entitled to rely on any such
information provided by GMACM, and the successor Servicer shall not be liable
for any errors in such information.

                  (iv) An Advance Financing Person who receives an assignment or
pledge of rights to receive Advance Reimbursement Amounts and/or whose
obligations are limited to the funding of Advances and/or Servicing Advances
pursuant to an Advance Facility shall not be required to meet the criteria for
qualification as GMACM.

                  (v) As between GMACM 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 GMACM 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 GMACM'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 GMACM or its related
Advance Financing Person in error, then GMACM's Assignee shall be required to
remit any portion of

                                     -101-
<PAGE>

such Advance Reimbursement Amount to each Person entitled to such portion of
such Advance Reimbursement Amount. Without limiting the generality of the
foregoing, GMACM shall remain entitled to be reimbursed by the Advance Financing
Person for all Advances and/or Servicing Advances funded by GMACM to the extent
the related Advance Reimbursement Amounts have not been assigned or pledged to
such Advance Financing Person or GMACM's Assignee.

                  (vi) For purposes of any Officer's Certificate of GMACM
delivered pursuant to Section 5.01(a), any Nonrecoverable Advance referred to
therein may have been made by GMACM. In making its determination that any
Advance or Servicing Advance theretofore made has become a Nonrecoverable
Advance, GMACM shall apply the same criteria in making such determination
regardless of whether such Advance or Servicing Advance shall have been made by
GMACM.

                  (vii) Any amendment to this Section 5.01(b) or to any other
provision of this Agreement that may be necessary or appropriate to effect the
terms of an Advance Facility as described generally in this Section 5.01(b),
including amendments to add provisions relating to a successor Servicer, may be
entered into by the Trustee, the Depositor and GMACM without the consent of any

         Section 5.05. ALLOCATION OF GROUP I REALIZED LOSSES.

                  (a) On or prior to each Determination Date, the Trustee shall
determine the amount of any Realized Loss in respect of each Group I Mortgage
Loan that occurred during the immediately preceding calendar month.

                  (b) The interest portion of Group I Realized Losses shall be
allocated to the Group I Certificates as described in Section 1.02 hereof.

                  (c) The principal portion of each Group I Realized Loss shall
be allocated as follows:

                           FIRST, to the Class I-B-6 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           SECOND, to the Class I-B-5 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           THIRD, to the Class I-B-4 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           FOURTH, to the Class I-B-3 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           FIFTH, to the Class I-B-2 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           SIXTH, to the Class I-B-1 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                           SEVENTH, to the Class I-A-1 Certificates until the
                           Certificate Principal Balance thereof has been
                           reduced to zero;

                  (d) Notwithstanding the foregoing clause (c), no such
allocation of any Group I Realized Loss shall be made on a Distribution Date to
any Class of Group I Certificates to the extent that such allocation would
result in the reduction of the aggregate Certificate Principal Balances of all
the Group I Certificates as of such Distribution Date, after giving effect to
all distributions and prior allocations of Group I Realized Losses on such date,
to an amount less than the aggregate Stated Principal Balance of all of the
Group I Mortgage Loans as of the first day of the month of such Distribution
Date (such limitation, the "Loss Allocation Limitation").

                  (e) Any Group I Realized Losses allocated to a Class of Group
I Certificates shall be allocated among the Group I Certificates of such Class
in proportion to their respective Certificate Principal Balances. Any allocation
of Group I Realized Losses shall be accomplished by reducing the Certificate
Principal Balances of the related Group I Certificates on the related
Distribution Date.

<PAGE>

                  (f) Group I Realized Losses shall be allocated on the
Distribution Date in the month following the month in which such loss was
incurred and, in the case of the principal portion thereof, after giving effect
to distributions made on such Distribution Date.

                  (g) On each Distribution Date, the Trustee shall determine the
Subordinate Certificate Writedown Amount. Any such Subordinate Certificate
Writedown Amount shall effect a corresponding reduction in the Certificate
Principal Balance of the Group I Subordinate Certificates, in the reverse order
of their which reduction shall occur on such Distribution Date after giving
effect to distributions made on such Distribution Date.

                  (h) Any Net Interest Shortfall shall be allocated among the
Classes of Group I Certificates in proportion to the respective amounts of
Accrued Certificate Interest that would have been allocated thereto in the
absence of such Net Interest Shortfall for such Distribution Date. The interest
portion of any Group I Realized Losses occurring on or prior to the Cross-Over
Date will not be allocated among any Group I Certificates, but will reduce the
amount of Group I Available Funds on the related Distribution Date. As a result
of the subordination of the Group I Subordinate Certificates in right of
distribution, such Group I Realized Losses will be borne by the Group I
Subordinate Certificates in reverse order of their payment priority. Following
the Cross-Over Date, the interest portion of Realized Losses on the Group I
Mortgage Loans will be allocated to the Class I-A-1 Certificates.

                  (i) Notwithstanding anything to the contrary contained herein,
if on any Distribution Date the Trustee discovers, based solely on the reports
delivered by the Servicers under this Agreement, the M&T Servicing Agreement and
the GreenPoint Servicing Agreement , that any Subsequent Recoveries have been
collected by the Servicers with respect to the Group I Mortgage Loans, the
Trustee shall reinstate the amount of the Certificate Principal Balance of the
Outstanding Class of Certificates with the lowest payment priority which was
reduced as a result of the allocation of Realized Losses on such Distribution
Date or any prior Distribution Date. To the extent that the amount of the
Subsequent Recoveries collected by the Servicers exceeds the amount of Group I
Realized Losses allocated to the Outstanding Class of Group I Certificates since
the Closing Date, the Trustee shall (i) reinstate and reissue any retired
Private Certificate, beginning with the retired Class of Private Certificates
having the most senior payment priority, for which Realized Losses were
allocated on any Distribution Date since the Closing Date and (ii) use
reasonable efforts to, to the extent permitted by the Depository, reinstate and
reissue any retired Book-Entry Certificate, beginning with the retired Class of
Book-Entry Certificates having the most senior payment priority, for which Group
I Realized Losses were allocated on any Distribution Date since the Closing
Date.

         Section 5.06. ALLOCATION OF GROUP II REALIZED LOSSES.

                  (a) On or prior to each Determination Date, the Trustee shall
determine the amount of any Group II Realized Loss in respect of each Group II
Mortgage Loan that occurred during the immediately preceding calendar month.

                  (b) The interest portion of Group II Realized Losses shall be
allocated to the Certificates as described in Section 1.02 hereof.

<PAGE>

                  (c) The principal portion of all Realized Losses on the Group
II Mortgage Loans allocated to any REMIC II Regular Interest pursuant to Section
5.06 (e) shall be allocated on each Distribution Date as follows: first, in
reduction of the Net Monthly Excess Cashflow; second, to the Class II-C
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; third, to the Class II-M-3 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; fourth, to the Class II-M-2
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; and fifth, to the Class II-M-1 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero. All such Realized Losses to
be allocated to the Certificate Principal Balances of all such Classes on any
Distribution Date shall be so allocated after the actual distributions to be
made on such date as provided above. All references above to the Certificate
Principal Balance of any Class of Certificates shall be to the Certificate
Principal Balance of such Class immediately prior to the relevant Distribution
Date, before reduction thereof by any Realized Losses, in each case to be
allocated to such Class of Certificates, on such Distribution Date.

                  Any allocation of the principal portion of Realized Losses to
a Group II Mezzanine Certificate on any Distribution Date shall be made by
reducing the Certificate Principal Balance thereof by the amount so allocated;
any allocation of Group II Realized Losses to a Class II-C Certificates shall be
made by reducing the amount otherwise payable in respect thereof pursuant to
Section 5.04(b) clause THIRD. No allocations of any Realized Losses shall be
made to the Certificate Principal Balances of the Group II Senior Certificates
or Class II-P Certificates.

                  All such Group II Realized Losses and all other losses
allocated to a Class of Group II Certificates hereunder will be allocated among
the Certificates of such Class in proportion to the Percentage Interests
evidenced thereby.

                  (d) The principal portion of all Realized Losses on the
Mortgage Loans shall be allocated on each Distribution Date first, to REMIC II
Regular Interest LTII-2 and REMIC II Regular Interest LTII-IIP, until the
Uncertificated Principal Balances have been reduced to zero and then to REMIC II
Regular Interest LTII-IO-A, REMIC II Regular Interest LTII-IO-B, REMIC II
Regular Interest LTII-IO-C, REMIC II Regular Interest LTII-IO-D, REMIC II
Regular Interest LTII-IO-E, REMIC II Regular Interest LTII-IO-F, REMIC II
Regular Interest LTII-IO-G and REMIC I Regular Interest LTII-IO-H, sequentially,
until the Uncertificated Principal Balances of each such REMIC II Regular
Interest have been reduced to zero.

                  (e) All Realized Losses on the REMIC II Regular Interests
shall be allocated on each Distribution Date to the following REMIC III Regular
Interests in the specified percentages, as follows: first, to Uncertificated
Accrued Interest payable to the REMIC III Regular Interest LTIII-AA and REMIC
III Regular Interest LTIII-IIZZ up to an aggregate amount equal to the REMIC III
Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the
Uncertificated Principal Balances of the REMIC III Regular Interest LTIII-AA and
REMIC III Regular Interest LTIII-IIZZ up to an aggregate amount equal to the
REMIC III Principal Loss Allocation Amount, 98% and 2%, respectively; third, to
the Uncertificated Principal Balances of REMIC III Regular Interest LTII-AA,
REMIC III Regular Interest LTIII-IIM3 and REMIC III Regular Interest LTIII-IIZZ,
98%, 1% and 1%, respectively, until the

                                     -110-
<PAGE>

Uncertificated Principal Balance of REMIC III Regular Interest LTIII-IIM3 has
been reduced to zero; fourth, to the Uncertificated Principal Balances of REMIC
III Regular Interest LTIII-AA, REMIC III Regular Interest LTIII-IIM2 and REMIC
III Regular Interest LTIII-IIZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC III Regular Interest LTIII-IIM2 has
been reduced to zero; and fifth, to the Uncertificated Principal Balances of
REMIC III Regular Interest LTIII-AA, REMIC III Regular Interest LTIII-IIM1 and
REMIC III Regular Interest LTIII-IIZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC III Regular Interest LTIII-IIM1 has
been reduced to zero.

                  (f) Notwithstanding anything to the contrary contained herein,
if on any Distribution Date the Trustee discovers, based solely on the reports
delivered by the related Servicer under this Agreement or under the M&T
Servicing Agreement or the GreenPoint Servicing Agreement, as applicable, that
any Subsequent Recoveries have been collected by the related Servicer with
respect to a Group II Mortgage Loan, the amount of such Subsequent Recoveries
will be applied to increase the Certificate Principal Balance of the Class of
Group II Mezzanine Certificates with the highest payment priority to which Group
II Realized Losses have been allocated, but not by more than the amount of Group
II Realized Losses previously allocated to that Class of Group II Mezzanine
Certificates pursuant to this Section 5.06. The amount of any remaining
Subsequent Recoveries will be applied to sequentially increase the Certificate
Principal Balance of the Group II Mezzanine Certificates, beginning with the
Class of Group II Mezzanine Certificates with the next highest payment priority,
up to the amount of such Group II Realized Losses previously allocated to such
Class of Certificates pursuant to this Section 5.06. Holders of such
Certificates will not be entitled to any payment in respect of current interest
on the amount of such increases for any Accrual Period preceding the
Distribution Date on which such increase occurs. Any such increases shall be
applied to the Certificate Principal Balance of each Group II Mezzanine
Certificate of such Class in accordance with its respective Percentage Interest.

         Section 5.07. MONTHLY STATEMENTS TO CERTIFICATEHOLDERS.

                  (a) Not later than each Distribution Date, the Trustee shall

Interest for such Distribution Date, plus (B) any amounts in respect thereof
remaining unpaid from previous Distribution Dates. Amounts payable as

                  (a) 98.00% of such remainder (other than amounts payable under

amount shall be distributed to REMIC III Regular Interest LTIII-IIP, until $100

Regular Interest LTIII-IIZZ until the Uncertificated Principal Balance of such
REMIC III Regular Interest is reduced to zero; then

                  (c) any remaining amount to the Holders of the Class II-R
Certificates; and

                  (iii) third, to REMIC III Regular Interest LTIII-IIP, 100% of
the amount paid in respect of REMIC II Regular Interest LTII-IIP;

                  provided, however, that (i) 98.00% and (ii) 2.00% of any
principal payments that are attributable to an Overcollateralization Reduction
Amount shall be allocated to Holders of (i) REMIC III Regular Interest LTIII-AA
and (ii) REMIC III Regular Interest LTIII-IIZZ, respectively; provided that

Alternative Loan Trust 2005-AP1 Class I-P Certificate Account". On the Closing
Date, the Depositor will deposit, or cause to be deposited in the Class I-P

Certificate Account". On the Closing Date, the Depositor will deposit, or cause
to be deposited in the Class II-P Certificate Account $100.00. The amount on
deposit in the Class II-P Certificate Account shall be held uninvested. On the
February 2010 Distribution Date, the Trustee shall withdraw the amount on
deposit in the Class II-P Certificate Account and remit such amount to REMIC II
Regular Interest LTII-P, from REMIC II Regular Interest LTII-P to REMIC III
Regular Interest LTIII-P and from REMIC III Regular Interest, LTIII-P to the
Holders of the Class II-P Certificates, in reduction of the Certificate
Principal Balance thereof.

         Section 5.11. NET WAC RESERVE FUND.

                  (a) The Trustee shall establish a Net WAC Reserve Fund on
behalf of the holders of the Group II Offered Certificates (other than the Class
II-A-IO Certificates). The Net WAC Reserve Fund must be an Eligible Account. The
Net WAC Reserve Fund shall be entitled "Net WAC Reserve Fund, Wells Fargo Bank,
National Association as Trustee for the benefit of holders of Nomura Asset
Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-AP1,
Class II-A-1, Class II-A-2, Class II-A-3, Class II-A-4, Class II-A-5, Class
II-M-1, Class II-M-2 and Class II-M-3". Any payments received by the Trustee
under the Cap Contract shall be deposited into the Net WAC Reserve Fund for the
benefit of the Group II Senior Certificates and Group II Mezzanine Certificates;
provided that the amount of any Excess Cap Payments shall be held for the
benefit of the Class II-C Certificates and payable as part of the Class II-C
Distribution Amount for the related Distribution Date. On the Closing Date, the
Depositor will deposit, or cause to be deposited, into the Net WAC Reserve Fund
$5,000. On each Distribution Date as to which there is a Net WAC Rate Carryover
Amount payable to any Class of Certificates, the Trustee shall deposit the
amounts pursuant to paragraph [4 of clause THIRD of Section 5.04(b) into the Net
WAC Reserve Fund and the Trustee has been directed by the Class II-C
Certificateholder to distribute such amounts to the Holders of the Group II
Offered Certificates (other than the Class II-A-IO Certificates) up to the Net
WAC Carryover Amount, payable to each such Class, first to the Group II Senior
Certificates (other than the Class II-A-IO Certificates) on a pro rata basis,
based on the entitlement of each such Class and then to the Class II-M-1, Class
II-M-2 and Class II-M-3 Certificates, in that order.

                  (b) The Net WAC Reserve Fund is an "outside reserve fund"
within the meaning of Treasury Regulation ss.1.860G-2(h) and shall be an asset
of the Trust Fund but not an asset of any REMIC. The Trustee on behalf of the
Trust shall be the nominal owner of the Net WAC Reserve Fund. The Class II-C
Certificateholders shall be the beneficial owners of the Net WAC Reserve Fund,
subject to the power of the Trustee to transfer amounts under Section 5.04(b).
Amounts in the Net WAC Reserve Fund shall be held either uninvested in a trust
or deposit account of the Trustee with no liability for interest or other
compensation thereof or, at the written direction of the Majority Class II-C
Certificateholder, be invested in Permitted Investments that mature no later
than the Business Day prior to the next succeeding Distribution Date. All net
income and gain from such investments shall be distributed to the Majority Class
II-C Certificateholder, not as a distribution in respect of any interest in any
REMIC, on such Distribution Date. All amounts earned on amounts on deposit in
the Net WAC Reserve Fund shall be taxable to the Majority Class II-C
Certificateholder. Any losses on such investments shall be deposited in the Net
WAC Reserve Fund by the Majority Class II-C Certificateholder out of its own
funds immediately as realized. In the event that the Majority Class II-C

                                     -117-
<PAGE>

Certificateholder shall fail to provide investment instructions to the Trustee,
the amounts on deposit in the Net WAC Reserve Fund shall be held uninvested.

                  (c) For federal tax return and information reporting, the
value of the right of the holder of the Class II-A-1 Certificates to receive
payments from the Net WAC Reserve Fund shall be $9,000 and the amount allocated
to the right of the holders of the Group II Offered Certificates (other than the
Class II-A-1 Certificates and the Class II-A-IO Certificates) to receive
payments from the Net WAC Reserve Fund in respect of any Net WAC Rate Carryover
Amount shall be zero.

         The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer upon the written order of the
Depositor. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized
to sign on behalf of the Trustee shall bind the Trustee, 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 the countersignature of the Trustee by manual
signature, and such countersignature upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
countersigned and delivered hereunder. All Certificates shall be dated the date
of their countersignature. On the Closing Date, the Trustee shall authenticate
the Certificates to be issued at the written direction of the Depositor, or any
affiliate thereof.

                                     -119-

         The Depositor shall provide, or cause to be provided, to the Trustee on
a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

         Section 6.02. CERTIFICATE REGISTER; REGISTRATION OF TRANSFER AND
EXCHANGE OF CERTIFICATES.

                  (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 6.09, a Certificate Register for the
Trust Fund in which, subject to the provisions of subsections (b) and (c) below
and to such reasonable regulations as it may prescribe, the Trustee shall
provide for the registration of Certificates and of Transfers and exchanges of
Certificates as herein provided. Upon surrender for registration of Transfer of
any Certificate, the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

                  At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee 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 Trustee duly executed by the
holder thereof or his attorney duly authorized in writing.

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

                  All Certificates surrendered for registration of Transfer or
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

                  (b) No Transfer of a Private 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 each certify
to the Trustee in writing the facts surrounding the Transfer in substantially
the forms set forth in Exhibit E (the "Transferor Certificate") and (x) deliver
a letter in substantially the form of either Exhibit F (the "Investment Letter")
or Exhibit G (the "Rule 144A Letter") or (y) there shall be delivered to the
Trustee an Opinion of Counsel, at the expense of the transferor, 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 Seller, the
Trustee or the Trust Fund. The Depositor shall provide to any Holder of a
Private Certificate and any prospective transferee designated by any such
Holder, information

                                     -120-
<PAGE>
regarding the related Certificates and the Mortgage Loans and such other
information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for Transfer of any such Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee shall cooperate with the Depositor
in providing the Rule 144A information referenced in the preceding sentence,
including providing to the Depositor such information 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 Private Certificate desiring to effect such
Transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor
and the Seller against any liability that may result if the Transfer is not so
exempt or is not made in accordance with such federal and state laws.

                  No Transfer of an ERISA Restricted Certificate shall be made
unless the Trustee shall have received either (i) a representation from the
transferee of such Certificate acceptable to and in form and substance
satisfactory to the Trustee to the effect that such transferee is not an
employee benefit plan subject to Section 406 of ERISA and/or a plan subject to
Section 4975 of the Code, or a Person acting on behalf of any such plan or using
the assets of any such plan, or (ii) in the case of any such ERISA Restricted
Certificate presented for registration in the name of an employee benefit plan
subject to ERISA, or a plan subject to Section 4975 of the Code (or comparable
provisions of any subsequent enactments), or a trustee of any such plan or any
other person acting on behalf of any such plan, an Opinion of Counsel
satisfactory to the Trustee for the benefit of the Trustee, the Depositor and
the Servicers and on which they may rely to the effect that the purchase and
holding of such ERISA Restricted Certificate is permissible under applicable
law, will not result in any prohibited transactions under ERISA or Section 4975
of the Code and will not subject the Trustee, the Depositor or any Servicer to
any obligation in addition to those expressly undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Trustee, the Depositor
or any Servicer. Notwithstanding anything else to the contrary herein, any
purported transfer of an ERISA Restricted Certificate to or on behalf of an
employee benefit plan subject to Section 406 of ERISA and/or a plan subject to
Section 4975 of the Code other than in compliance with the foregoing shall be
void and of no effect; provided that the restriction set forth in this sentence
shall not be applicable if there has been delivered to the Trustee an Opinion of
Counsel meeting the requirements of clause (ii) of the first sentence of this
paragraph. The Trustee shall not be under any liability to any Person for any
registration of transfer of any ERISA Restricted Certificate that is in fact not
permitted by this Section 6.02(b) or for making any payments due on such
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement. The Trustee shall be
entitled, but not obligated, to recover from any Holder of any ERISA Restricted
Certificate that was in fact an employee benefit plan subject to Section 406 of
ERISA or a plan subject to Section 4975 of the Code or a Person acting on behalf
of any such plan at the time it became a Holder or, at such subsequent time as
it became such a plan or Person acting on behalf of such a plan, all payments
made on such ERISA Restricted Certificate at and after either such time. Any
such payments so recovered by the Trustee shall be paid and delivered by the
Trustee to the last preceding Holder of such Certificate that is not such a plan
or Person acting on behalf of a plan.

                  Each beneficial owner of a Group I Subordinate Certificate or
Group II Mezzanine Certificate or any interest therein shall be deemed to have
represented, by virtue of its

                                     -121-
<PAGE>
acquisition or holding of that certificate or interest therein, that either (i)
it is not a Plan or investing with "Plan Assets", (ii) in the case of
Certificates other than the Class I-B-4, Class I-B-5 and Class I-B-6
Certificates, it has acquired and is holding such certificate in reliance on the
Exemption, and that it understands that there are certain conditions to the
availability of the Exemption, including that the certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by S&P or
Moody's, and the certificate is so rated or (iii) (1) it is an insurance
company, (2) the source of funds used to acquire or hold the certificate or
interest therein is an "insurance company general account," as such term is
defined in Prohibited Transaction Class Exemption ("PTCE") 95-60 and (3) the
conditions in Sections I and III of PTCE 95-60 have been satisfied.

                  (c) Each Person who has or who acquires any Ownership Interest
in a Residual 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 Residual
Certificate are expressly subject to the following provisions:

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

                  (ii) No Ownership Interest in a Residual Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Residual Certificate
         unless, in addition to the certificates required to be delivered to the
         Trustee under subparagraph (b) above, the Trustee shall have been
         furnished with an affidavit (a "Transfer Affidavit") of the initial
         owner or the proposed transferee in the form attached hereto as Exhibit
         D.

                  (iii) Each Person holding or acquiring any Ownership Interest
         in a Residual 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 Residual 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 Residual Certificate and (C) not to Transfer its Ownership Interest
         in a Residual Certificate or to cause the Transfer of an Ownership
         Interest in a Residual Certificate to any other Person if it has actual
         knowledge that such Person is not a Permitted Transferee.

                  (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Residual Certificate in violation of the provisions of
         this Section 6.02(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 Residual Certificate in violation of the
         provisions of this Section 6.02(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 Residual
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Residual Certificate that is in fact
         not permitted by Section 6.02(b) and this Section 6.02(c) or for making
         any payments due on such Certificate to

                                     -122-
<PAGE>

         the Holder thereof or taking any other action with respect to such
         Holder under the provisions of this Agreement so long as the Transfer
         was registered after receipt of the related Transfer Affidavit. The
         Trustee shall be entitled but not obligated to recover from any Holder
         of a Residual 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 Residual
         Certificate at and after either such time. Any such payments so
         recovered by the Trustee shall be paid and delivered by the Trustee to
         the last preceding Permitted Transferee of such Certificate.

                  The restrictions on Transfers of a Residual Certificate set
forth in this Section 6.02(c) shall cease to apply (and the applicable portions
of the legend on a Residual Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee or the Seller to
the effect that the elimination of such restrictions will not cause REMIC I,
REMIC II, REMIC III and/or REMIC IV, as applicable, 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, a Certificateholder or another Person.
Each Person holding or acquiring any ownership Interest in a Residual
Certificate hereby consents to any amendment of this Agreement that, based on an
Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Residual
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 Residual Certificate that is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

                  (d) The preparation and delivery of all certificates and
opinions referred to above in this Section 6.02 shall not be an expense of the
Trust Fund, the Trustee, the Depositor or the Seller.

         Section 6.03. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

         If (a) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is delivered to
the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Trustee that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute, authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
Class, tenor and Percentage Interest. In connection with the issuance of any new
Certificate under this Section 6.03, the Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Trustee) connected therewith. Any replacement Certificate issued pursuant to
this Section 6.03 shall constitute complete and indefeasible evidence of
ownership in the Trust Fund, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time. All Certificates
surrendered to the Trustee under the terms of this Section 6.03 shall be
canceled and destroyed by the Trustee in accordance with its standard procedures
without liability on its part.

         The Trustee and any of their agents may treat the person in whose name
any Certificate is registered as the owner of such Certificate for the purpose

affected by any notice to the contrary.

         Section 6.05. ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
ADDRESSES.

         If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the
Depositor shall request such information in writing from the Trustee, then the
Trustee shall, within ten Business Days after the receipt of such request,
provide the Depositor or such Certificateholders at such recipients' expense the
most recent list of the Certificateholders of the Trust Fund held by the
Trustee, if any. The Depositor and every Certificateholder, by receiving and
holding a Certificate, agree that the Trustee shall not be held accountable by
reason of the disclosure of any such information as to the list of the

Register in the name of the Depository or its nominee, and no Certificate Owner
of such Certificates will receive a definitive certificate representing such

Owners of such Certificates;

                  (c) registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;

                  (d) the rights of the respective Certificate Owners of such
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 such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued pursuant to Section 6.08, the Depository will make
book-

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

Participants) owning Book-Entry Certificates evidencing the requisite percentage
of principal amount of such Class of Certificates.

         Section 6.07. NOTICES TO DEPOSITORY.

         Whenever any notice or other communication is required to be given to
Certificateholders of a 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 Trustee shall give all such notices and
communications to the Depository.

         Section 6.08. DEFINITIVE CERTIFICATES.

         If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depositor or the Depository advises the Trustee that the
Depository is no longer willing or able to discharge properly its
responsibilities under the Depository Agreement with respect to such
Certificates and the Trustee or the Depositor is unable to locate a qualified
successor, (b) the Depositor, at its sole option, advises the Trustee that it
elects to terminate the book-entry system with respect to such Certificates
through the Depository or (c) after the occurrence and continuation of an Event
of Default, Certificate Owners of such Book-Entry Certificates having not less
than 51% of the Voting Rights evidenced by any Class of Book-Entry Certificates
advise the Trustee and the Depository in writing through the Depository
Participants that the continuation of a book-entry system with respect to
Certificates of such Class through the Depository (or its successor) is no
longer in the best interests of the Certificate Owners of such Class, then the
Trustee shall notify all Certificate Owners of such Certificates, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Certificates to applicable Certificate Owners requesting the same.
The Depositor shall provide the Trustee with an adequate inventory of
certificates to facilitate the issuance and transfer of Definitive Certificates.
Upon surrender to the Trustee of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall countersign and deliver such Definitive Certificates. Neither
the Depositor nor the Trustee shall be liable for any delay in delivery of such
instructions and each may conclusively rely on, and

                                     -125-

shall be protected in relying on, such instructions. Upon the issuance of such
Definitive Certificates, all references herein to obligations imposed upon or to
be performed by the Depository shall be deemed to be imposed upon and performed
by the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

         Section 6.09. MAINTENANCE OF OFFICE OR AGENCY.

         The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies at Sixth Street and Marquette Avenue,

transfer or exchange. The Trustee will give prompt written notice to the
Certificateholders of any change in such location of any such office or agency.

                             THE DEPOSITOR AND GMACM

         Section 7.01. LIABILITIES OF THE DEPOSITOR AND GMACM. Each of the
Depositor and GMACM shall be liable in accordance herewith only to the extent of
the obligations specifically imposed upon and undertaken by it herein.
Notwithstanding anything herein to the contrary, the obligations of GMACM as
Servicer under this Agreement relate solely to the GMACM Mortgage Loans. GMACM
shall have no obligations, including but not limited to those of
indemnification, relating to the M&T Mortgage Loans.

         Section 7.02. MERGER OR CONSOLIDATION OF THE DEPOSITOR OR GMACM.

                  (a) Each of the Depositor and GMACM will keep in full force
and effect its rights and franchises as a corporation under the laws of the
state of its incorporation, and will 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, the Certificates or any of the Mortgage Loans
and to perform its duties under this Agreement.

                  (b) Any Person into which the Depositor or GMACM may be merged
or consolidated, or any corporation resulting from any merger or consolidation
to which the Depositor or GMACM shall be a party, or any Person succeeding to
the business of the Depositor or GMACM shall be the successor of the Depositor
or GMACM hereunder, 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.

         Section 7.03. INDEMNIFICATION OF DEPOSITOR AND GMACM.

                  (a) The Depositor agrees to indemnify the Indemnified Persons
for, and to hold them harmless against, any loss, liability or expense
(including reasonable legal fees and disbursements of counsel) incurred on their
part that may be sustained in connection with, arising out of, or relating to,
any claim or legal action (including any pending or threatened claim or legal
action) relating to this Agreement or the Certificates (i) related to the
Depositor's failure to perform its duties in compliance with this Agreement
(except as any such loss, liability or expense shall be otherwise reimbursable
pursuant to this Agreement) or (ii) incurred by reason of the Depositor's
willful misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder. This indemnity shall survive the resignation and the termination of
this Agreement.

                  (b) GMACM agrees to indemnify the Indemnified Persons for, and
to hold them harmless against, any loss, liability or expense (including
reasonable legal fees and disbursements of counsel) incurred on their part that
may be sustained in connection with, arising out of, or relating to, any claim
or legal action (including any pending or threatened claim or legal action)
relating to GMACM's gross negligence in the performance of its duties under this
Agreement or failure to service the GMACM Mortgage Loans in material compliance
with the terms of this Agreement and for a material breach of any
representation, warranty or covenant of

                                     -127-

made by a third party with respect to this Agreement or the GMACM Mortgage
Loans, assume (with the consent of the Trustee and with counsel reasonably
satisfactory to the Trustee) the defense of any such claim and pay all expenses
in connection therewith, including counsel fees, and promptly appeal or pay,
discharge and satisfy any judgment or decree which may be entered against it or
any Indemnified Person in respect of such claim but failure to so notify GMACM
shall not limit its obligations hereunder. GMACM agrees that it will not enter
into any settlement of any such claim without the consent of the Indemnified
Persons unless such settlement includes an unconditional release of such
Indemnified Persons from all liability that is the subject matter of such claim.
The provisions of this Section 7.03(b) shall survive termination of this
Agreement.

         Section 7.04. LIMITATIONS ON LIABILITY OF THE DEPOSITOR, GMACM AND

pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, GMACM or any such Person against
any breach of warranties or representations made herein or any liability which
would otherwise be imposed by reason of such Person's willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder.

                  (b) The Depositor, GMACM and any director, officer, employee
or agent of the Depositor and GMACM may rely in good faith on any document of
any kind prima facie properly executed and submitted by any Person respecting
any matters arising hereunder.

                  (c) The Depositor, GMACM, the Trustee, the Custodian and any
director, officer, employee or agent of the Depositor, GMACM, the Trustee or the
Custodian shall be indemnified by the Trust Fund and held harmless thereby
against any loss, liability or either expense (including reasonable legal fees
and disbursements of counsel) incurred on their part that may be sustained in
connection with, arising out of, or related to, any claim or legal action
(including any pending or threatened claim or legal action) relating to this
Agreement or the Certificates, other than (i) with respect to GMACM, such loss,
liability or expense related to GMACM's failure to perform its duties in
compliance with this Agreement (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) or, with respect to
the Custodian, to the Custodian's failure to perform its duties hereunder, (ii)

its duties hereunder or (iii) with respect to the Custodian, any such loss,
liability or expense incurred by reason of the Custodian's willful misfeasance,
bad faith or gross negligence in the performance of its duties hereunder.

                  (d) Neither the Depositor nor GMACM shall be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties under this

                                     -128-
<PAGE>

Agreement and that in its opinion may involve it in any expense or liability;
provided, however, the Trustee may in its discretion, undertake any such action
which it may deem necessary or desirable with respect to this Agreement and the
rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom shall be expenses, costs and
liabilities of the Trust Fund, and the Trustee shall be entitled to be
reimbursed therefor out of the Distribution Account as provided by Section 4.05.
Nothing in this Subsection 7.04(d) shall affect the Trustee's obligation to take
such actions as are necessary to ensure the servicing and administration of the
Mortgage Loans pursuant to this Agreement.

                  (e) In taking or recommending any course of action pursuant to
this Agreement, unless specifically required to do so pursuant to this
Agreement, the Trustee shall not be required to investigate or make
recommendations concerning potential liabilities which the Trust might incur as
a result of such course of action by reason of the condition of the Mortgaged
Properties.

                  (f) The Trustee shall not be liable for any acts or omissions
of GMACM, the Depositor or the Custodian.

         Section 7.05. GMACM NOT TO RESIGN.

         GMACM shall not resign from the obligations and duties hereby imposed
on it except upon the determination that its duties hereunder are no longer
permissible under applicable law or the performance of such duties are no longer
possible in order to comply with applicable law and such incapacity or
impossibility cannot be cured by GMACM. Any determination permitting the
resignation of GMACM shall be evidenced by an Opinion of Counsel to such effect
delivered to the Trustee which Opinion of Counsel shall be in form and substance
acceptable to the Trustee. No appointment of a successor to GMACM shall be
effective hereunder unless (a) the Rating Agencies have confirmed in writing
that such appointment will not result in a downgrade, qualification or
withdrawal of the then current ratings assigned to the Certificates, (b) such
successor shall have represented that it is meets the eligibility criteria set
forth in Section 8.02 and (c) such successor has agreed to assume the
obligations of GMACM hereunder to the extent of the GMACM Mortgage Loans. GMACM
shall provide a copy of the written confirmation of the Rating Agencies and the
agreement executed by such successor to the Trustee. No such resignation shall
become effective until a Qualified Successor or the Trustee shall have assumed
GMACM's responsibilities and obligations hereunder. GMACM shall notify the
Trustee and the Rating Agencies of its resignation.

         Section 7.06. TERMINATION OF GMACM WITHOUT CAUSE; APPOINTMENT OF
SPECIAL SERVICER.

                  (a) The Seller may, at its option, terminate the servicing
responsibilities of GMACM as Servicer hereunder with respect to the GMACM
Mortgage Loans without cause. No such termination shall become effective unless
and until a successor to GMACM shall have been appointed to service and
administer the GMACM Mortgage Loans pursuant to the terms and conditions of this
Agreement. No appointment shall be effective unless (i) such successor to GMACM
meets the eligibility criteria contained in Section 8.02, (ii) the Trustee shall
have

                                     -129-

writing that such appointment will not result in a downgrade, qualification or
withdrawal of the then current ratings assigned to the Certificates, (iv) such
successor has agreed to assume the obligations of GMACM hereunder to the extent
of the GMACM Mortgage Loans and (v) all amounts reimbursable to GMACM pursuant
to the terms of this Agreement shall have been paid to GMACM by the successor
appointed pursuant to the terms of this Section 7.06 or by the Seller including
without limitation, all unreimbursed Advances and Servicing Advances made by
GMACM and all out-of-pocket expenses of GMACM incurred in connection with the
transfer of servicing to such successor. The Seller shall provide a copy of the
written confirmation of the Rating Agencies and the agreement executed by such
successor to the Trustee.

                  (b) In addition, the Seller may, at its option, appoint a
special servicer with respect to certain of the GMACM Mortgage Loans. The Seller
and GMACM shall negotiate in good faith with any proposed special servicer with
respect to the duties and obligations of such special servicer with respect to
any such GMACM Mortgage Loan. Any subservicing agreement shall contain terms and
provisions acceptable to the Trustee and shall obligate the special servicer to
subservice such GMACM Mortgage Loans in accordance with Accepted Servicing
Practices. The fee payable to the special servicer for the performance of such
duties and obligations will be paid from the Servicing Fee collected by GMACM
with respect to each such GMACM Mortgage Loan and will be remitted to such
special servicer by GMACM.

                        DEFAULT; TERMINATION OF SERVICER

         Section 8.01. SERVICER DEFAULT.

         In case one or more of the following events of default by a Servicer
(each, a "Servicer Default") shall occur and be continuing, that is to say:

                  (i) any failure by GMACM to remit to the Trustee any payment
required to be made under the terms of this Agreement which continues unremedied
for a period of three Business Days; or

                  (ii) failure on the part of GMACM to duly observe or perform
in any material respect any other of the covenants or agreements on the part of
GMACM set forth in this Agreement, the breach of which has a material adverse

on which written notice of such failure, requiring the same to be remedied,
shall have been given to GMACM by the Trustee or to GMACM and the Trustee by 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 conservator or receiver
or liquidator in any insolvency, bankruptcy, 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 GMACM and such
decree or order shall have remained in force undischarged or unstayed for a
period of sixty days; or

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

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

                  (vi) GMACM attempts to assign its right to servicing
compensation hereunder (other than any payment by GMACM to the Seller of any
portion of the Servicing Fee payable to GMACM as provided in a separate side
letter between the Seller and GMACM) or GMACM attempts to sell or otherwise
dispose of all or substantially all of its property or assets or to assign this
Agreement or the servicing responsibilities hereunder or to delegate its duties
hereunder or any portion thereof except, in each case as otherwise permitted
herein; or

<PAGE>

                  (vii) GMACM ceases to be qualified to transact business in any
jurisdiction where it is currently so qualified, but only to the extent such
non-qualification materially and adversely affects GMACM's ability to perform
its obligations hereunder; or

                  (viii) a default by M&T under the M&T Servicing Agreement; or

                  (ix) a default by GreenPoint under the GreenPoint Servicing
Agreement.

         then, and in each and every such case, so long as a Servicer Default
shall not have been remedied, the Trustee, by notice in writing to the related
Servicer shall with respect to a payment default by the related Servicer
pursuant to Section 8.01(i) of this Agreement or pursuant to the M&T Servicing
Agreement or GreenPoint Servicing Agreement, as applicable, and, upon the
occurrence and continuance of any other Servicer Default, may, and, at the
written direction of Certificateholders evidencing not less than 25% of the
Voting Rights shall, in addition to whatever rights the Trustee on behalf of the
Certificateholders may have under Section 7.03 or under the M&T Servicing
Agreement or the GreenPoint Servicing Agreement and at law or equity to damages,
including injunctive relief and specific performance, terminate all the rights
and obligations of GMACM under this Agreement and in and to the related Mortgage
Loans and the proceeds thereof without compensating GMACM for the same with
respect to a default by GMACM, or terminate all the rights and obligations of
M&T under the M&T Servicing Agreement or GreenPoint under the GreenPoint
Servicing Agreement and in and to the related Mortgage Loans in accordance with
the M&T Servicing Agreement or the GreenPoint Servicing Agreement, as
applicable; provided, that in addition to the notice provided for in the
preceding sentence, the Trustee shall first provide written notice to M&T within
two Business Days following the occurrence of a payment default by M&T in
accordance with the M&T Servicing Agreement. On or after the receipt by a
Servicer of such written notice, all authority and power of such Servicer under
this Agreement, the M&T Servicing Agreement or the GreenPoint Servicing
Agreement, as applicable, whether with respect to the related Mortgage Loans or
otherwise, shall pass to and be vested in the Trustee. Upon written request from
the Trustee, the related Servicer shall prepare, execute and deliver, any and
all documents and other instruments, place in the Trustee's possession all
Mortgage Files relating to the related Mortgage Loans, and 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 related Mortgage Loans and related documents, or otherwise, at
such Servicer's sole expense. GMACM, pursuant to this Agreement, M&T pursuant to
the M&T Servicing Agreement or GreenPoint pursuant to the GreenPoint Servicing
Agreement, shall cooperate with the Trustee in effecting the termination of the
related Servicer's responsibilities and rights hereunder, under the M&T
Servicing Agreement or under the GreenPoint Servicing Agreement, as applicable,
including, without limitation, the transfer to such successor for administration
by it of all cash amounts which shall at the time be credited by the defaulting
Servicer to its Custodial Account or Escrow Account or thereafter received with
respect to the related Mortgage Loans or any related REO Property (provided,
however, that the defaulting Servicer shall continue to be entitled to receive
all amounts accrued or owing to it under this Agreement, under the M&T Servicing
Agreement or under the GreenPoint Servicing Agreement, as applicable, on or
prior to the date of such termination, whether in respect of Advances, Servicing
Advances, accrued and unpaid Servicing Fees or otherwise, and shall continue to
be entitled to the benefits of Section 7.04,

                                     -132-

notwithstanding any such termination, with respect to events occurring prior to
such termination). The Trustee shall not have knowledge of a Servicer Default
unless a Responsible Officer of the Trustee has actual knowledge or unless
written notice of any Servicer Default is received by the Trustee at its
Corporate Trust Office and such notice references the Certificates, the Trust
Fund or this Agreement. Notwithstanding the Servicer Default set forth in
clauses (viii) and (ix) above, there shall be no cross-default between the
Servicers.

         Section 8.02. TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

         On and after the time a Servicer receives a notice of termination
pursuant to Section 8.01 or pursuant to the M&T Servicing Agreement or
GreenPoint Servicing Agreement, as applicable, the Trustee shall become the
successor to such Servicer with respect to the transactions set forth or
provided for herein or under the M&T Servicing Agreement or GreenPoint Servicing
Agreement and after a transition period (not to exceed 90 days), shall be
subject to all the responsibilities, duties and liabilities relating thereto
placed on such Servicer by the terms and provisions hereof or the M&T Servicing
Agreement or GreenPoint Servicing Agreement, as applicable, and applicable law
including the obligation to make Advances pursuant to Article VI hereof or
pursuant to the M&T Servicing Agreement or GreenPoint Servicing Agreement,
except as otherwise provided herein; provided, however, that the Trustee's
obligation to make Advances in its capacity as Successor Servicer shall not be
subject to such 90 day transition period and the Trustee in such capacity will
make any Advance required to be made by the terminated Servicer on the
Distribution Date on which the terminated Servicer was required to make such
Advance. Effective on the date of such notice of termination, as compensation
therefor, the Trustee shall be entitled to all fees, costs and expenses relating
to the Mortgage Loans that the terminated Servicer would have been entitled to
if it had continued to act hereunder or under the M&T Servicing Agreement or
GreenPoint Servicing Agreement, as applicable, provided, however, that the
Trustee shall not be (i) liable for any acts or omissions of the terminated
Servicer, (ii) obligated to make Advances if it is prohibited from doing so
under applicable law or determines that such Advance, if made, would constitute
a Nonrecoverable Advance, (iii) responsible for expenses of the terminated
Servicer pursuant to Section 2.03 or pursuant to the M&T Servicing Agreement or
GreenPoint Servicing Agreement or (iv) obligated to deposit losses on any
Permitted Investment directed by the terminated Servicer. Notwithstanding the
foregoing, the Trustee may, if it shall be unwilling to so act, or shall, if it
is prohibited by applicable law from making Advances pursuant to Article VI of
this Agreement or pursuant to the M&T Servicing Agreement or GreenPoint
Servicing Agreement 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 does not adversely affect the
then current rating of the Certificates by each Rating Agency as the successor
to the Servicer hereunder or under the M&T Servicing Agreement or GreenPoint
Servicing Agreement, as applicable, in the assumption of all or any part of the
responsibilities, duties or liabilities of the Servicer hereunder or under the
M&T Servicing Agreement or GreenPoint Servicing Agreement, as applicable. Any
Successor Servicer shall (i) be an institution that 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 (ii) be willing to act as successor servicer of any Mortgage
Loans under this Agreement or under the M&T Servicing Agreement or GreenPoint
Servicing Agreement, as applicable, and shall have executed and delivered to the
Depositor and the Trustee an agreement accepting such delegation and

                                     -133-

assignment, that contains an assumption by such Person of the rights, powers,
duties, responsibilities, obligations and liabilities of the terminated Servicer
(other than any liabilities of the terminated Servicer hereof incurred prior to
termination of the Servicer under Section 8.01), with like effect as if
originally named as a party to this Agreement or the M&T Servicing Agreement or
GreenPoint Servicing Agreement, as applicable, provided that each Rating Agency
shall have acknowledged in writing 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. If the Trustee assumes
the duties and responsibilities of the terminated Servicer in accordance with
this Section 8.02, the Trustee shall not resign as servicer until a Successor
Servicer has been appointed and has accepted such appointment. Pending
appointment of a successor to the terminated Servicer hereunder, the Trustee,
unless the Trustee is prohibited by law from so acting, shall, subject to
Section 4.04 hereof, act in such capacity as hereinabove provided. In connection
with such appointment and assumption, the Trustee may make such arrangements for
the compensation of such successor out of payments on related Mortgage Loans or
otherwise as it and such successor shall agree; provided that no such
compensation shall be in excess of that permitted the terminated Servicer
hereunder or under the M&T Servicing Agreement or GreenPoint Servicing
Agreement. The Trustee and such successor shall take such action, consistent
with this Agreement or the M&T Servicing Agreement or GreenPoint Servicing
Agreement, as applicable, as shall be necessary to effectuate any such
succession. Neither the Trustee nor any other Successor Servicer shall be deemed
to be in default hereunder by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either case caused by the failure of the related Servicer to deliver or
provide, or any delay in delivering or providing, any cash, information,
documents or records to it.

         The costs and expenses of the Trustee in connection with the
termination of a Servicer, appointment of a Successor Servicer and, if
applicable, any transfer of servicing, including, without limitation, all costs
and 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 Trustee to correct any errors or insufficiencies in the servicing data or
otherwise to enable the Trustee or the Successor Servicer to service the related
Mortgage Loans properly and effectively, to the extent not paid by the
terminated Servicer as may be required herein or under the M&T Servicing
Agreement or GreenPoint Servicing Agreement, as applicable, shall be payable to
the Trustee from the Distribution Account pursuant to Section 4.07. Any
successor to the terminated Servicer as successor servicer under this Agreement
or the M&T Servicing Agreement or GreenPoint Servicing Agreement, as applicable,
shall give notice to the applicable Mortgagors of such change of servicer and
shall, during the term of its service as successor servicer maintain in force
the policy or policies that the terminated Servicer is required to maintain
pursuant to Section 3.04 or pursuant to the M&T Servicing Agreement or
GreenPoint Servicing Agreement, as applicable.

         Section 8.03. NOTIFICATION TO CERTIFICATEHOLDERS.

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

                                     -134-
<PAGE>

                  (b) Within 60 days after the occurrence of any Servicer
Default, the Trustee shall transmit by mail to all Certificateholders notice of
each such Servicer Default hereunder known to the Trustee, unless such default
shall have been cured or waived.

         Section 8.04. WAIVER OF SERVICER DEFAULTS.

         The Trustee may waive only by written notice from Certificateholders
evidencing 66-2/3 of the Voting Rights (unless such default materially and
adversely affects all Certificateholders, in which case the written direction
shall be from all of the Certificateholders) any default by a Servicer in the
performance of its obligations hereunder or under the M&T Servicing Agreement or
GreenPoint Servicing Agreement, as applicable, and its consequences. Upon any
such waiver of a past default, such default shall cease to exist, and any
Servicer Default arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereon except to the extent
expressly so waived in writing.

                                   ARTICLE IX

                             CONCERNING THE TRUSTEE

         Section 9.01. DUTIES OF TRUSTEE.

                  (a) The Trustee, prior to the occurrence of a Servicer
Default, and after the curing or waiver of all Servicer Defaults, which may have
occurred undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement as duties of the Trustee. If a Servicer
Default has occurred and has not been cured or waived, the Trustee shall
exercise such of the rights and powers vested in it by this Agreement, and the
same degree of care and skill in their exercise, as a prudent person would
exercise under the circumstances in the conduct of such Person's own affairs.

                  (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee pursuant to any provision of this
Agreement, the Trustee shall examine them to determine whether they are in the
form required by this Agreement; provided, however, that the Trustee shall not
be responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Servicers.

                  (c) On each Distribution Date, the Trustee shall make monthly
distributions and the final distribution to the Certificateholders from funds in
the Distribution Accounts as provided in Sections 5.04 and 10.01 based the
applicable Remittance Report.

                  (d) No provision of this Agreement shall be construed to
relieve the Trustee from liability for its own grossly negligent action, its own
grossly negligent failure to act or its own willful misconduct; provided,
however, that:

                  (i) Prior to the occurrence of a Servicer Default and after
         the curing or waiver of all Servicer Defaults which may have occurred
         with respect to the Trustee, the duties and obligations of the Trustee
         shall be determined solely by the express provisions of this Agreement,
         the Trustee shall not be liable except for the performance of its
         duties and obligations as are specifically set forth in this Agreement,
         no implied covenants or obligations shall be read into this Agreement
         against the Trustee and, in the absence of bad faith on the part of the
         Trustee, the Trustee may conclusively rely and shall be fully protected
         in acting or refraining from acting, as to the truth of the statements
         and the correctness of the opinions expressed therein, upon any
         certificates or opinions furnished to the Trustee and conforming to the
         requirements of this Agreement;

                  (ii) The Trustee shall not be liable in its individual
         capacity for an error of judgment made in good faith by a Responsible
         Officer or Responsible Officers of the Trustee unless it shall be
         proved that the Trustee was grossly negligent in ascertaining the
         pertinent facts;

                  (iii) The Trustee shall not be liable with respect to any
         action taken, suffered or omitted to be taken by it in good faith and
         believed by it to be authorized or within the

                                     -136-
<PAGE>

         rights or powers conferred upon it by this Agreement, the M&T Servicing
         Agreement and the GreenPoint Servicing Agreement or in accordance with
         the directions of the Holders of Certificates evidencing not less than
         25% of the aggregate Voting Rights of the Certificates, if such action
         or non-action relates to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee or exercising any
         trust or other power conferred upon the Trustee under this Agreement,
         the M&T Servicing Agreement and the GreenPoint Servicing Agreement;

                  (iv) The Trustee shall not be required to take notice or be
         deemed to have notice or knowledge of any default or Servicer Default
         unless a Responsible Officer of the Trustee shall have actual knowledge
         thereof. In the absence of such notice, the Trustee may conclusively
         assume there is no such default or Servicer Default;

                  (v) The Trustee shall not in any way be liable by reason of
         any insufficiency in any Account held by or in the name of Trustee
         unless it is determined by a court of competent jurisdiction that the
         Trustee's gross negligence or willful misconduct was the primary cause
         of such insufficiency (except to the extent that the Trustee is obligor
         and has defaulted thereon);

                  (vi) Anything in this Agreement, the M&T Servicing Agreement
         or the GreenPoint Servicing Agreement to the contrary notwithstanding,
         in no event shall the Trustee be liable for special, indirect, punitive
         or consequential loss or damage of any kind whatsoever (including but
         not limited to lost profits), even if the Trustee has been advised of
         the likelihood of such loss or damage and regardless of the form of
         action and whether or not any such damages were foreseeable or
         contemplated; and

                  (vii) None of the Seller, the Depositor or the Trustee shall
         be responsible for the acts or omissions of the other, it being
         understood that this Agreement shall not be construed to render them
         partners, joint venturers or agents of one another.

The Trustee shall not be required to expend or risk its own funds or otherwise
incur liability, financial or otherwise, in the performance of any of its duties
hereunder or under the M&T Servicing Agreement or GreenPoint Servicing
Agreement, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement or in the M&T Servicing
Agreement or GreenPoint Servicing Agreement shall in any event require the
Trustee to perform, or be responsible for the manner of performance of, any of
the obligations of the terminated Servicer hereunder or under the M&T Servicing
Agreement or GreenPoint Servicing Agreement.

                  (e) All funds received by the Trustee and required to be
deposited in the Distribution Accounts pursuant to this Agreement will be
promptly so deposited by the Trustee.

         Section 9.02. CERTAIN MATTERS AFFECTING THE TRUSTEE.

                  (a) Except as otherwise provided in Section 9.01:

                                     -137-
<PAGE>

                  (i) The Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting in reliance on any
         resolution or certificate of the Seller, the Depositor or any Servicer,
         any certificates of auditors or any other certificate, statement,
         instrument, opinion, report, notice, request, consent, order,
         appraisal, bond or other paper or document believed by it to be genuine
         and to have been signed or presented by the proper party or parties;

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

                  (iii) The Trustee shall not be under any obligation to
         exercise any of the trusts or powers vested in it by this Agreement,
         other than its obligation to give notices pursuant to this Agreement,
         or to institute, conduct or defend any litigation hereunder or in
         relation hereto at the request, order or direction of any of the
         Certificateholders pursuant to the provisions of this Agreement, unless
         such Certificateholders shall have offered to the Trustee reasonable
         security or indemnity satisfactory to it against the costs, expenses
         and liabilities which may be incurred therein or thereby. Nothing
         contained herein shall, however, relieve the Trustee of the obligation,
         upon the occurrence of a Servicer Default of which a Responsible
         Officer of the Trustee has actual knowledge (which has not been cured
         or waived), to exercise such of the rights and powers vested in it by
         this Agreement, and to use the same degree of care and skill in their
         exercise, as a prudent person would exercise under the circumstances in
         the conduct of his own affairs;

                  (iv) The Trustee shall not be liable in its individual
         capacity for any action taken, suffered or omitted by it in good faith
         and believed by it to be authorized or within the discretion or rights
         or powers conferred upon it by this Agreement, the M&T Servicing
         Agreement or the GreenPoint Servicing Agreement;

                  (v) The Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, approval, bond or other paper or document, unless requested in
         writing to do so by Holders of Certificates evidencing not less than
         25% of the aggregate Voting Rights of the Certificates and provided
         that the payment within a reasonable time to the Trustee of the costs,
         expenses or liabilities likely to be incurred by it in the making of
         such investigation is, in the opinion of the Trustee reasonably assured
         to the Trustee by the security afforded to it by the terms of this
         Agreement. The Trustee may require reasonable indemnity against such
         expense or liability as a condition to taking any such action. The
         reasonable expense of every such examination shall be paid by the
         Certificateholders requesting the investigation;

                  (vi) The Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or through
         Affiliates, nominees, custodians, agents or attorneys. The Trustee
         shall not be liable or responsible for the misconduct or negligence

                                     -138-
<PAGE>

         of any of the Trustee's agents or attorneys or paying agent appointed
         hereunder by the Trustee with due care;

                  (vii) Should the Trustee deem the nature of any action
         required on its part to be unclear, the Trustee may require prior to
         such action that it be provided by the Depositor with reasonable
         further instructions; the right of the Trustee to perform any
         discretionary act enumerated in this Agreement, in the M&T Servicing
         Agreement or in the GreenPoint Servicing Agreement shall not be
         construed as a duty, and the Trustee shall not be accountable for other
         than its gross negligence or willful misconduct in the performance of
         any such act;

                  (viii) The Trustee shall not be required to give any bond or
         surety with respect to the execution of the trust created hereby or the
         powers granted hereunder;

                  (ix) The Trustee shall not have any duty to conduct any
         affirmative investigation as to the occurrence of any condition
         requiring the repurchase of any Mortgage Loan by any Person pursuant to
         this Agreement, or the eligibility of any Mortgage Loan for purposes of
         this Agreement;

                  (x) The Trustee shall have no duty hereunder with respect to
         any complaint, claim, demand, notice or other document it may receive
         or which may be alleged to have been delivered or served upon it by the
         parties as a consequence of the assignment of any Mortgage Loan
         hereunder; provided, however that the Trustee shall promptly remit to
         the related Servicer upon receipt any such complaint, claim, demand,
         notice or other document (i) which is delivered to the Trustee at is
         Corporate Trust Office, (ii) of which a Responsible Officer has actual
         knowledge or (iii) which contains information sufficient to permit the
         Trustee to make a determination that the real property to which such
         document relates is a Mortgaged Property; and

                  (xi) The Trustee is hereby directed by the Depositor to
         execute the Cap Contract on behalf of the Trust Fund in the form
         presented to it by the Depositor and shall have no responsibility for
         the contents of the Cap Contract, including, without limitation, the
         representations and warranties contained therein. Any funds payable by
         the Trustee under the Cap Contract at closing shall be paid by the
         Depositor. Notwithstanding anything to the contrary contained herein or
         in the Cap Contract, the Trustee shall not be required to make any
         payments to the counterparty under the Cap Contract.

         Section 9.03. TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

         The recitals contained herein and in the Certificates (other than the
signature and authentication of the Trustee on the Certificates) shall be taken
as the statements of the Depositor, and the Trustee shall not have any
responsibility for their correctness. The Trustee does not make any
representation as to the validity or sufficiency of the Certificates (other than
the signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan except as expressly provided in Sections 2.02 and 2.06. The
Trustee's signature and authentication (or authentication of its agent) on the
Certificates shall be solely in its capacity as

                                     -139-
<PAGE>

Trustee and shall not constitute the Certificates an obligation of the Trustee
in any other capacity. The Trustee shall not be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor with respect to the Mortgage Loans. The Trustee shall not be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. The Trustee
shall not at any time have any responsibility or liability for or with respect
to the legality, validity and enforceability of the M&T Servicing Agreement, the
GreenPoint Servicng Agreement, the Cap Contract, the Custodial Agreement or any
Mortgage or any Mortgage Loan, or the perfection and priority of any Mortgage or
the maintenance of any such perfection and priority, or for or with respect to
the sufficiency of the Trust Fund or its ability to generate the payments to be
distributed to Certificateholders, under this Agreement. The Trustee shall not
have any responsibility for filing any financing or continuation statement in
any public office at any time or to otherwise perfect or maintain the perfection
of any security interest or lien granted to it hereunder or to record this
Agreement.

         Section 9.04. TRUSTEE MAY OWN CERTIFICATES.

         The Trustee in its individual capacity or in any capacity other than as
Trustee hereunder may become the owner or pledgee of any Certificates with the
same rights it would have if it were not the Trustee and may otherwise deal with
the parties hereto.

         Section 9.05. TRUSTEE'S COMPENSATION AND EXPENSES; INDEMNIFICATION.

                  (a) As compensation for the performance of its obligations
under this Agreement, the Trustee shall be entitled to all income and gain
realized from any investment of funds in the Distribution Account.

                  In addition, the Trustee will be entitled to recover from the
related Distribution Account pursuant to Section 4.07 all reasonable
out-of-pocket expenses, disbursements and advances and the expenses of the
Trustee in connection with the performance of its duties and obligations
hereunder or under any related documents, any Servicer Default, any breach of
this Agreement or any claim or legal action (including any pending or threatened
claim or legal action) incurred or made by the Trustee in the administration of
the trusts hereunder (including the reasonable compensation, expenses and
disbursements of its counsel) except any such expense, disbursement or advance
as may arise from its gross negligence or intentional misconduct provided,
however that to the extent that any such amounts are due the Trustee and are not
specifically related to the Group I Mortgage Loans or Group II Mortgage Loans,
then the payment of such amounts to the Trustee shall be made from amounts on
deposit in both Distribution Accounts, on a pro rata basis, based on the amounts
then on deposit in the Distribution Accounts. If funds in the Distribution
Account are insufficient therefor, the Trustee shall recover such expenses from
the Seller. Such compensation and reimbursement obligation shall not be limited
by any provision of law in regard to the compensation of a trustee of an

                                     -140-

express trust. The rights of the Trustee under this Section 9.05 shall survive
the termination of this Agreement and the resignation or removal of the Trustee.

                  (b) The Trustee and its directors, officers, agents and
employees shall be indemnified and held harmless by the Trust Fund against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever, including reasonable attorney's fees, that may be imposed on,
incurred by or asserted against it or them in any way directly or indirectly
relating to or arising out of the transactions contemplated by this Agreement or
any other agreement entered into in connection herewith, including, but not
limited to, the Mortgage Loan Purchase Agreement assigned to the Trust pursuant
to this Agreement, the M&T Servicing Agreement assigned to the Trust pursuant to
the M&T Assignment Agreement, the GreenPoint Servicing Agreement assigned to the
Trust pursuant to the GreenPoint Assignment Agreement, the Custodial Agreement
or the Cap Contract or any action taken or not taken by it or them hereunder or
in connection herewith except to the extent caused by the Trustee's gross
negligence or willful misconduct. The indemnification provided for under this
Section 9.05 shall survive the termination of this Agreement and the resignation
or removal of the Trustee.

                  The Trustee and its directors, officers, agents and employees
shall be indemnified and held harmless by the Trust Fund from and against any
and all claims, demands, losses, penalties, liabilities, costs, damages,
injuries and expenses, including, without limitation, reasonable attorneys' fees
and expenses, suffered or sustained by the Trustee, either directly or
indirectly, relating to or arising out of any environmental law or regulation of
the United States or any state thereof, including, without limitation, any
judgment, award, settlement, reasonable attorneys' fees and expenses and other
costs or expenses incurred in connection with the defense of any actual or
threatened action, proceeding or claim.

         Section 9.06. ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

         The Trustee and any successor Trustee shall during the entire duration
of this Agreement be a state bank or trust company or a national banking
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 and undivided profits of at least
$40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to

and, in the case of a successor Trustee other than pursuant to Section 9.10,
rated in one of the two highest long-term debt categories of, or otherwise
acceptable to, each of the Rating Agencies. If the Trustee 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 9.06 the combined capital and surplus of such corporation shall be
deemed to be its total equity capital (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 9.06, the Trustee shall resign immediately in the manner and with the
effect specified in Section 9.08.

         Section 9.07. INSURANCE.

         The Custodian hereunder, at its own expense, shall at all times
maintain and keep in full force and effect such insurance in amounts, with
standard coverage and subject to deductibles, as are customary for insurance
typically maintained by banks which act as custodians but, in any event not less
than that required by Fannie Mae. Evidence of such insurance shall be furnished
to any Certificateholder upon reasonable written request.

         Section 9.08. RESIGNATION AND REMOVAL OF TRUSTEE.

         The Trustee may at any time resign and be discharged from the Trust
hereby created by giving written notice thereof to the Depositor and the Seller,
with a copy to the Rating Agencies. Upon receiving such notice of resignation,
the Depositor shall promptly appoint a successor trustee by written instrument,
in triplicate, one copy of which instrument shall be delivered to the resigning
trustee and the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation or removal, the resigning or removed 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 9.06 hereof and shall fail to resign after
written request thereto by the Depositor, (ii) the Trustee shall become
incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or
(iii)(A) a tax is imposed with respect to the Trust Fund by any state in which
the Trustee or the Trust Fund is located, (B) the imposition of such tax would
be avoided by the appointment of a different trustee and (C) the Trustee fails
to indemnify the Trust Fund against such tax, then the Depositor may remove the
Trustee and appoint a successor trustee by written instrument, in multiple
copies, a copy of which instrument shall be delivered to the Trustee and the
successor trustee.

         The Holders evidencing at least 51% of the Voting Rights of each Class
of Certificates may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in multiple copies, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered by the successor trustee to the Trustee so
removed and the successor trustee so appointed. Notice of any removal of the
Trustee shall be given to each Rating Agency by the Trustee or successor
trustee.

         Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 9.08 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 10.09 hereof.

         Section 9.09. SUCCESSOR TRUSTEE.

         Any successor trustee appointed as provided in Section 9.08 hereof
shall execute, acknowledge and deliver to the Depositor and to its predecessor
trustee an instrument accepting such appointment hereunder and thereupon the
resignation or removal of the predecessor trustee

                                     -142-
<PAGE>

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 9.09 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 9.07 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 9.09, the successor trustee shall mail notice of the succession of
such trustee hereunder to all Holders of Certificates. If the successor trustee
fails to mail such notice within ten days after acceptance of appointment, the
Depositor shall cause such notice to be mailed at the expense of the Trust Fund.

         Section 9.10. MERGER OR CONSOLIDATION OF TRUSTEE.

         Any corporation, state bank or national banking association into which
the Trustee may be merged or converted or with which it may be consolidated or
any corporation, state bank or national banking association resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation, state bank or national banking association succeeding to
substantially all of the corporate trust business of the Trustee or shall be the
successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 9.06 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.

         Section 9.11. 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 Trustee shall have the power and shall execute and deliver
all instruments to appoint one or more Persons approved by the Trustee 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 9.11, such
powers, duties, obligations, rights and trusts as the Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
9.06 and no notice to Certificateholders of the appointment of any co-trustee or
separate trustee shall be required under Section 9.09.

                  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 as
         Successor Servicer under this Agreement to advance funds on behalf of
         the terminated Servicer, shall be conferred or

                                     -143-
<PAGE>

         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 a Trustee hereunder or as a Successor
         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 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 IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Depositor. The Trust Fund shall pay associated fees and expenses.

         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 9.12. TAX MATTERS.

         It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC formed hereunder
qualifies as, a "real estate mortgage investment conduit" as defined in and in
accordance with the REMIC Provisions. In furtherance of such intention, the
Trustee covenants and agrees that it shall act as agent (and the Trustee is
hereby appointed to act as agent) on behalf of the Trust Fund. The Trustee, as
agent on behalf of the Trust Fund, shall do or refrain from doing, as
applicable, the following: (a) the Trustee shall prepare and file, or cause to
be prepared and filed, in a timely manner, U.S. Real Estate Mortgage Investment
Conduit Income Tax Returns (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
such REMIC containing such information and

                                     -144-
<PAGE>

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) the Trustee shall apply for an
employer identification number with the Internal Revenue Service via a Form SS-4
or other comparable method for each REMIC that is or becomes a taxable entity,
and 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 the Trust Fund; (c) the Trustee shall make or cause to be made elections, on
behalf of each REMIC formed hereunder to be treated as a REMIC on the federal
tax return of such REMIC for its first taxable year (and, if necessary, under
applicable state law); (d) the Trustee shall prepare and forward, or cause to be
prepared and forwarded, to the Certificateholders and to the Internal Revenue
Service and, if necessary, state tax authorities, all information returns and
reports as and when required to be provided to them in accordance with the REMIC
Provisions, including without limitation, the calculation of any original issue
discount using the Prepayment Assumption; (e) the Trustee shall provide
information necessary for the computation of tax imposed on the transfer of a
Residual 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) the Trustee shall, to the extent under its control, conduct
the affairs of the Trust Fund at all times that any Certificates are outstanding
so as to maintain the status of each REMIC formed hereunder as a REMIC under the
REMIC Provisions; (g) the Trustee shall not knowingly or intentionally take any
action or omit to take any action that would cause the termination of the REMIC
status of any REMIC formed hereunder; (h) the Trustee shall pay, from the
sources specified in the last paragraph of this Section 9.12, the amount of any
federal, state and local taxes, including prohibited transaction taxes as
described below, imposed on any REMIC formed hereunder prior to the termination
of the Trust Fund when and as the same shall be due and payable (but such
obligation shall not prevent the Trustee or any other appropriate Person from
contesting any such tax in appropriate proceedings and shall not prevent the
Trustee from withholding payment of such tax, if permitted by law, pending the
outcome of such proceedings); (i) the Trustee shall sign or cause to be signed
federal, state or local income tax or information returns or any other document
prepared by the Trustee pursuant to this Section 9.12 requiring a signature
thereon by the Trustee; (j) the Trustee shall maintain records relating to each
REMIC formed hereunder including but not limited to the income, expenses, assets
and liabilities of each such REMIC 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; (k) the
Trustee shall, for federal income tax purposes, maintain books and records with
respect to the REMICs on a calendar year and on an accrual basis; (l) the
Trustee shall not enter into any arrangement not otherwise provided for in this
Agreement by which the REMICs will receive a fee or other compensation for
services nor permit the REMICs to receive any income from assets other than
"qualified mortgages" as defined in Section 860G(a)(3) of the Code or "permitted
investments" as defined in Section 860G(a)(5) of the Code; and (m) as and when
necessary and appropriate,

                                     -145-
<PAGE>

the Trustee shall represent the Trust Fund 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
REMIC formed hereunder, enter into settlement agreements with any governmental
taxing agency, extend any statute of limitations relating to any tax item of the
Trust Fund, and otherwise act on behalf of each REMIC formed hereunder in
relation to any tax matter involving any such REMIC.

         In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order to
enable the Trustee to perform its duties as set forth herein. The Depositor
hereby indemnifies the Trustee for any losses, liabilities, damages, claims or
expenses of the Trustee arising from any errors or miscalculations of the
Trustee that result from any failure of the Depositor to provide, or to cause to
be provided, accurate information or data to the Trustee on a timely basis.

         In the event that any tax is imposed on "prohibited transactions" of
any of REMIC I, REMIC II, REMIC III or REMIC IV as defined in Section 860F(a)(2)
of the Code, on the "net income from foreclosure property" of the Trust Fund as
defined in Section 860G(c) of the Code, on any contribution to any of REMIC I,
REMIC II, REMIC III or REMIC IV after the startup day pursuant to Section
860G(d) of the Code, or any other tax is imposed, including, without limitation,
any federal, state or local tax or minimum tax imposed upon any of REMIC I,
REMIC II, REMIC III or REMIC IV, and is not paid as otherwise provided for
herein, such tax shall be paid by (i) the Trustee, if any such other tax arises
out of or results from a breach by the Trustee of any of its obligations under
this Section, (ii) any party hereto (other than the Trustee) to the extent any
such other tax arises out of or results from a breach by such other party of any
of its obligations under this Agreement or (iii) in all other cases, or in the
event that any liable party hereto fails to honor its obligations under the
preceding clauses (i) or (ii), any such tax will be paid first with amounts
otherwise to be distributed to the Class I-R Certificateholders, and second with
amounts otherwise to be distributed to all other Group I Certificateholders in
the following order of priority: first, to the Class I-B-6 Certificates, second,
to the Class I-B-5 Certificates, third, to the Class I-B-4 Certificates, fourth,
to the Class I-B-3 Certificates, fifth, to the Class I-B-2 Certificates, sixth,
to the Class I-B-1 Certificates and seventh, to the Class I-A-1 Certificates and
any such tax will be paid first with amounts otherwise to be distributed to the
Class II-R Certificateholders, and second with amounts otherwise to be
distributed to all other Group II Certificateholders in the following order of
priority: first, to the Class II-M-3 Certificates, second, to the Class II-M-2
Certificates, third, to the Class II-M-1 Certificates, and fourth, to the Group
II Senior Certificates (pro rata based on the amounts to be distributed).
Notwithstanding anything to the contrary contained herein, to the extent that
such tax is payable by the Holder of any Certificates, the Trustee is hereby
authorized to retain on any Distribution Date, from the Holders of the Residual
Certificates (and, if necessary, second, from the Holders of the other
Certificates in the priority specified in the preceding sentence), funds
otherwise

                                     -146-
<PAGE>

distributable to such Holders in an amount sufficient to pay such tax. The
Trustee shall include in its Remittance Report instructions as to distributions
to such parties taking into account the priorities described in the second
preceding sentence. The Trustee agrees to promptly notify in writing the party
liable for any such tax of the amount thereof and the due date for the payment
thereof. Notwithstanding the foregoing, however, in no event shall the Trustee
have any liability (1) for any action or omission that is taken in accordance
with and in compliance with the express terms of, or which is expressly
permitted by the terms of this Agreement, (2) for any losses other than arising
out of a grossly negligent performance by the Trustee of its duties and
obligations set forth herein, and (3) for any special or consequential damages
to Certificateholders (in addition to payment of principal and interest on the
Certificates).

such Mortgage Loans.

         Section 10.02. FINAL DISTRIBUTION ON THE CERTIFICATES.

         If on any Determination Date, (i) the Trustee determines based on the
reports delivered by the Servicers under this Agreement, the M&T Servicing
Agreement and the GreenPoint Servicing Agreement that there are no Outstanding
Mortgage Loans and no other funds or assets

                                     -148-
<PAGE>

in the Trust Fund other than the funds in the Distribution Accounts, the Trustee

a final distribution on such Class, the Trustee shall notify the
Certificateholders within five (5) 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 related Certificates at the office
of the Trustee set forth herein. If the Terminator elects to terminate the Trust
Fund pursuant to Section 10.01, at least 20 days prior to the date notice is to
be mailed to the Certificateholders, the Terminator shall notify the Trustee of
the date the Terminator intends to terminate the Trust Fund. The Terminator
shall remit the Mortgage Loan Purchase Price to the Trustee on the Business Day
prior to the Distribution Date for such Optional Termination by the Terminator.

         Notice of any termination of the Trust Fund, specifying the
Distribution Date on which Certificateholders may surrender their Certificates
for payment of the final distribution and cancellation, shall be given promptly
by the Trustee by letter to Certificateholders mailed not earlier than the 10th
day and no later than the 15th day of the month immediately preceding the month
of such final distribution. Any such notice shall specify (a) the Distribution
Date upon which final distribution on the Certificates will be made upon
presentation and surrender of Certificates at the office therein designated, (b)
the amount of such final distribution, (c) the location of the office or agency
at which such presentation and surrender must be made and (d) that the Record
Date otherwise applicable to such Distribution Date is not applicable,
distributions being made only upon presentation and surrender of the
Certificates at the office therein specified. The Trustee will give such notice
to each Rating Agency at the time such notice is given to Certificateholders.

         In the event such notice is given, the Terminator shall deposit in the
Distribution Account on the Business Day prior to the applicable Distribution
Date in an amount equal to the final distribution in respect of the
Certificates. Upon such final deposit with respect to the Trust Fund and the
receipt by the Custodian of a request for release therefor, the Custodian, on
behalf of the Trustee, shall promptly release to the Terminator, as applicable
the Mortgage Files for the Mortgage Loans and any documents necessary to
transfer any REO Property.

         Upon presentation and surrender of the Certificates, the Trustee shall

allocable to such Certificates held in the Distribution Account in the order and
priority set forth in Section 5.04 hereof on the final Distribution Date and in
proportion to their respective Percentage Interests.

         In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all the applicable Certificates shall not
have been surrendered for cancellation, the Trustee may take appropriate steps,
or may appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and

                                     -149-
<PAGE>

the cost thereof shall be paid out of the funds and other assets that remain a
part of the Trust Fund. If within two years 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 and the Trustee shall release such
funds upon written direction.

         Section 10.03. ADDITIONAL TERMINATION REQUIREMENTS.

                  (a) Upon exercise by the Terminator of its purchase option as
provided in Section 10.01, the Trust Fund or the applicable REMICs 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
Terminator, to the effect that the failure of the Trust Fund to comply with the
requirements of this Section 11.03 will not (i) result in the imposition of
taxes on "prohibited transactions" of a REMIC, or (ii) cause any REMIC to fail
to qualify as a REMIC at any time that any Certificates are outstanding:

                  (1) The Terminator shall establish a 90-day liquidation period
and notify the Trustee thereof, and the Trustee shall in turn specify the first
day of such period in a statement attached to the tax return for each of REMIC
I, REMIC II, REMIC III and REMIC IV at the time such REMIC is terminated
pursuant to Treasury Regulation Section 1.860F-1. The Terminator 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 Terminator;

                  (2) During such 90-day liquidation period, and at or prior to
the time of making the final payment on the Certificates, the Terminator shall
sell all of the assets of REMIC I, REMIC II, REMIC III and REMIC IV for cash;
and

                  (3) At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be distributed
or credited, to the Holders of the Residual Certificates all cash on hand (other
than cash retained to meet claims), and REMIC I shall terminate at that time.

                  (b) By their acceptance of the Certificates, the Holders
thereof hereby authorize the Terminator to specify the 90-day liquidation period
for REMIC I, REMIC II, REMIC III and REMIC IV, which authorization shall be
binding upon all successor Certificateholders.

                  (c) The Trustee as agent for each REMIC hereby agrees to adopt
and sign such a plan of complete liquidation upon the written request of the
Terminator, and the receipt of the Opinion of Counsel referred to in Section
10.03(a)(1) and to take such other action in connection therewith as may be
reasonably requested by the Terminator.

                  (d) If either, but not both, (i) the Group I Mortgage Loans or
(ii) the Group II Mortgage Loans are purchased pursuant to Section 10.01, this
section shall apply only to (i) REMIC I or (ii) REMIC II, REMI III and REMIC IV,
respectively.

                            MISCELLANEOUS PROVISIONS

         Section 11.01. AMENDMENT.

         This Agreement may be amended from time to time by parties hereto,
without the consent of any of the Certificateholders to cure any ambiguity, to
correct or supplement any provisions herein, to change the manner in which the
Distribution Accounts maintained by the Trustee or the Custodial Accounts
maintained by GMACM are maintained or to make such other provisions with respect
to matters or questions arising under this Agreement as shall not be
inconsistent with any other provisions herein if such action shall not, as
evidenced by an Opinion of Counsel, adversely affect in any material respect the
interests of any Certificateholder; provided that any such amendment shall be
deemed not to adversely affect in any material respect the interests of the
Certificateholders and no such Opinion of Counsel shall be required if the
Person requesting such amendment obtains a letter from each Rating Agency
stating that such amendment would not result in the downgrading or withdrawal of
the respective ratings then assigned to the Certificates.

         Notwithstanding the foregoing, the parties hereto 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 each of REMIC I, REMIC II, REMIC III and REMIC IV as a REMIC
under the Code or to avoid or minimize the risk of the imposition of any tax on
any of REMIC I, REMIC II, REMIC III or REMIC IV pursuant to the Code that would
be a claim against any of REMIC I, REMIC II, REMIC III or REMIC IV at any time
prior to the final redemption of the Certificates, provided that the Trustee has
been provided an Opinion of Counsel, which opinion shall be an expense of the
party requesting such opinion but in any case shall not be an expense of the
Trustee or the Trust Fund, 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 parties
hereto and the Holders of each Class of Certificates affected thereby evidencing
over 50% of the Voting Rights of such Class or Classes 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 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) cause
any of REMIC I, REMIC II, REMIC III or REMIC IV to cease to qualify as a REMIC
or (iii) reduce the aforesaid percentages of Certificates of each Class the
Holders of which are required to consent to any such amendment without the
consent of the Holders of all Certificates of such Class 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, which opinion shall be an expense of the party
requesting such amendment but in any case shall

                                     -151-
<PAGE>

not be an expense of the Trustee, to the effect that such amendment will not
(other than an amendment pursuant to clause (ii) of, and in accordance with, the
preceding paragraph) cause the imposition of any tax on REMIC I, REMIC II, REMIC
III or REMIC IV or the Certificateholders or cause REMIC I, REMIC II, REMIC III
or REMIC IV to cease to qualify as a REMIC at any time that any Certificates are
outstanding. Further, nothing in this Agreement shall require the Trustee to
enter into an amendment without receiving an Opinion of Counsel, satisfactory to
the Trustee that (i) such amendment is permitted and is not prohibited by this
Agreement and (ii) that all requirements for amending this Agreement (including
any consent of the applicable Certificateholders) have been complied with.

         Promptly after the execution of any amendment to this Agreement
requiring the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder and
each Rating Agency.

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

         Section 11.02. RECORDATION OF AGREEMENT; COUNTERPARTS.

         To the extent permitted by applicable law, this Agreement is subject to
recordation in all appropriate public offices for real property records in all
of the counties or other comparable jurisdictions in which any or all of the
Mortgaged Properties are situated, and in any other appropriate public recording
office or elsewhere. The Seller or the Depositor shall effect such recordation
at the Trust's expense upon the request in writing of a Certificateholder, but
only if such direction is accompanied by an Opinion of Counsel (provided at the
expense of the Certificateholder requesting recordation) to the effect that such
recordation would materially and beneficially affect the interests of the
Certificateholders or is required by law.

         For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, 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 11.03. 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 11.04. 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 Seller
to the Depositor, and by the Depositor to the Trust Fund be, and be construed
as, an absolute sale thereof to the Depositor or the Trust Fund, as applicable.
It is, further, not the intention of the parties that such conveyance be deemed
a pledge thereof by the Seller to the Depositor, or by the Depositor to the
Trust Fund. However, in the event that, notwithstanding the intent of the
parties, such assets are held to be the property of the Seller or the Depositor,
as applicable, 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) each conveyance provided for in this
Agreement shall be deemed to be an assignment and a grant by the Seller or the
Depositor, as applicable, for the benefit of the Certificateholders, of a
security interest in all of the assets that constitute the Trust Fund, whether
now owned or hereafter acquired.

         The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement.

         Section 11.05. NOTICES.

                  (a) The Trustee shall use its best efforts to promptly provide
         notice to each Rating Agency 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 Servicer of Default that has not
         been cured;

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

                  (iv) The final payment to Certificateholders.

                  In addition, the Trustee shall promptly furnish to each Rating
Agency copies of the following:

                  (i) Each annual statement as to compliance described in
         Section 3.16; and

                  (ii) Each annual independent public accountants' servicing
         report described in Section 4.17.

provided pursuant to Section 7.02, this Agreement may not be assigned by the
Seller or the Depositor.

         Section 11.08. 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.

                                     -154-
<PAGE>

         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 a Servicer 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 indemnity satisfactory to
it as it may require against the costs, expenses, and liabilities to be incurred
therein or thereby, and the Trustee or 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, or to obtain or seek
to obtain priority over or preference to any other such Holder 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 11.08, each and every Certificateholder or the
Trustee shall be entitled to such relief as can be given either at law or in

         evidencing a fractional undivided interest in the distributions
         allocable to the Class I-A-1 Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as a servicer, and Wells Fargo Bank, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the calendar
month immediately preceding the calendar month in which the related Distribution
Date occurs on the Certificate Principal Balance hereof at a per annum rate
equal to the weighted average Net Mortgage Rate of the Group I Mortgage Loans
minus 0.01% per annum The Trustee will distribute on the 25th day of each month,
or, if such 25th day is not a Business Day, the immediately following Business
Day (each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last day (or if such last day is not a Business
Day, the Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Group I Mortgage Loan and is not likely to
be the date on which the Certificate Principal Balance of this Class of
Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to

                                     A-1-3

<PAGE>

the address of the Person entitled thereto as such name and address shall appear
on the Certificate Register or, if such Person so requests by notifying the
Trustee in writing as specified in the Agreement. Notwithstanding the above, the
final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose and designated in such notice. The initial Certificate
Principal Balance of this Certificate is set forth above. The Certificate
Principal Balance hereof will be reduced to the extent of distributions
allocable to principal hereon and Realized Losses allocable hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Classes or Classes of Certificates affected thereby evidencing
over 50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent

                                     A-1-4

<PAGE>

of any of them may treat the Person in whose name this Certificate is registered
as the owner hereof for all purposes, and none of Depositor, the Trustee or any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group I Certificates (other than the obligations to make payments to the related
Certificateholders) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Group I Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group I
Mortgage Loan and (B) the remittance of all funds due under the Agreement with
respect to the Group I Mortgage Loans, or (ii) the optional repurchase by the
party named in the Agreement of all the Group I Mortgage Loans and other assets
of the Trust Fund relating to the Group I Mortgage Loans in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date in which the aggregate Stated Principal Balance of the
Group I Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group I Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group I Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class II-A-[1][2][3][4][5] Certificates with respect
         to a Trust Fund consisting primarily of a pool of conventional one- to
         four-family fixed interest rate mortgage loans sold by NOMURA ASSET
         ACCEPTANCE CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the

generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as a servicer, and Wells Fargo Bank, National

[CLASS II-A-1 CERTIFICATE ONLY: Interest on this Certificate will accrue during
the period beginning on the 25th day of the month immediately preceding the
month in which the related Distribution Date (as hereinafter defined) occurs
(or, with respect to the First Distribution specified above, the Closing Date)
to and including the 24th day of the month in which the related Distribution
Date occurs on the Certificate Principal Balance hereof at a per annum rate
equal to One-Month LIBOR plus [___]% per annum, subject a cap equal to the Net
WAC Cap Rate for such Distribution Date. The Trustee will distribute on the 25th
day of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the Business Day immediately preceding
such Distribution Date so long as this Certificate remains in book-entry form,
otherwise, on the last day (or if such last day is not a Business Day, the

immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Group II Mortgage Loan and is not likely
to be the date on which the Certificate Principal Balance of this Class of
Certificates will be reduced to zero.]

with respect to each Distribution Date which occurs thereafter, in each case,
subject to a cap equal to the Net WAC Rate Cap for such Distribution Date.] The
Trustee will distribute on the 25th day of each month, or, if such 25th day is
not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last day (or if such last day is not a Business Day, the
Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Group II Mortgage Loan and is not likely
to be the date on which the Certificate Principal Balance of this Class of
Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this

Certificate is set forth above. The Certificate Principal Balance hereof will be
reduced to the extent of distributions allocable to principal hereon.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Classes or Classes of Certificates affected thereby evidencing
over 50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Trustee or any such agent shall be affected
by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group II Certificates (other than the obligations to make payments to the
related Certificateholders) shall terminate

upon the earlier of (i) the later of (A) the maturity or other liquidation (or
Advance with respect thereto) of the last Group II Mortgage Loan remaining in
the Trust Fund and disposition of all property acquired upon foreclosure or deed
in lieu of foreclosure of any Group II Mortgage Loan and (B) the remittance of
all funds due under the Agreement with respect to the Group II Mortgage Loans,
or (ii) the optional repurchase by the party named in the Agreement of all the
Group II Mortgage Loans and other assets of the Trust Fund relating to the Group
II Mortgage Loans in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date in which the
aggregate Stated Principal Balance of the Group II Mortgage Loans is less than
the percentage of the aggregate Stated Principal Balance specified in the
Agreement of the Group II Mortgage Loans at the Cut-off Date. The exercise of
such right will effect the early retirement of the Group II Certificates. In no
event, however, will the Trust Fund created by the Agreement continue beyond the
earlier of (i) the expiration of 21 years after the death of certain persons
identified in the Agreement and (ii) the Last Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                                 SERIES 2005-AP1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class II-A-IO Certificates with respect to a Trust
         Fund consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as a servicer, and Wells Fargo Bank, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Notional Balance hereof at a per annum rate equal to the
lesser of (a)(i) 4.50% per annum for each Distribution Date from and including
the Distribution Date in March 2005 to and including the Distribution Date in
October 2005, (ii) 3.50% per annum for each Distribution Date from and including
the Distribution Date in November 2005 to and including the Distribution Date in
February 2007 and (iii) 0% for each Distribution Date thereafter and (b) the
weighted average of the Net Mortgage Rates of the Group II Mortgage Loans. The
Trustee will distribute on the 25th day of each month, or, if such 25th day is
not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last day (or if such last day is not a Business Day, the
Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount of interest required to be distributed to the Holders of
Certificates of the same Class as this Certificate.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to

                                     A-3-3

<PAGE>

the address of the Person entitled thereto as such name and address shall appear
on the Certificate Register or, if such Person so requests by notifying the
Trustee in writing as specified in the Agreement. Notwithstanding the above, the
final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose and designated in such notice. The initial Certificate Notional
Balance of this Certificate is set forth above.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner

                                     A-3-4

<PAGE>

hereof for all purposes, and none of Depositor, the Trustee or any such agent
shall be affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group I Certificates (other than the obligations to make payments to the related
Certificateholders) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Group I Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group I
Mortgage Loan and (B) the remittance of all funds due under the Agreement with
respect to the Group I Mortgage Loans, or (ii) the optional repurchase by the
party named in the Agreement of all the Group I Mortgage Loans and other assets
of the Trust Fund relating to the Group I Mortgage Loans in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date in which the aggregate Stated Principal Balance of the
Group I Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group I Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group I Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that [Cede & Co.] [Nomura Securities
International, Inc.] is the registered owner of the Percentage Interest
evidenced hereby in the beneficial ownership interest of Certificates of the
same Class as this Certificate in a trust (the "Trust Fund") generally
consisting of conventional first lien, fixed rate mortgage loans secured by one-
to four- family residences, units in planned unit developments and individual
condominium units (collectively, the "Mortgage Loans") sold by NAAC. The
Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the "Seller") to
NAAC. The Trust Fund was created pursuant to the Pooling and Servicing Agreement
dated as of the Cut-off Date specified above (the "Agreement"), among NAAC, as
depositor (the "Depositor"), the Seller, as seller, GMAC Mortgage Corporation,
as a servicer, and Wells Fargo Bank, National Association, as trustee (the
"Trustee"), a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, capitalized terms used herein
shall have the meaning ascribed to them in the Agreement. This Certificate is
issued under and is subject to the terms, provisions and conditions of the

                                     A-4-3

<PAGE>

Agreement, to which Agreement the Holder of this Certificate by virtue of its
acceptance hereof assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the calendar
month immediately preceding the calendar month in which the related Distribution
Date occurs on the Certificate Principal Balance hereof at a per annum rate
equal to the weighted average Net Mortgage Rate of the Group I Mortgage Loans
minus 0.01% per annum The Trustee will distribute on the 25th day of each month,
or, if such 25th day is not a Business Day, the immediately following Business
Day (each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last day (or if such last day is not a Business
Day, the Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Group I Mortgage Loan and is not likely to
be the date on which the Certificate Principal Balance of this Class of
Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such

                                     A-4-4

<PAGE>

consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  [Class I-B-[4][5][6]: No transfer of this Certificate shall be
made unless the transfer is made pursuant to an effective registration statement
under the Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller 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.]

                  [Class I-B-[1][2][3] only: Any transferee of this Certificate
shall be deemed to make the representations set forth in Section 6.02(b) of the
Agreement.]

                  [Class I-B-[4][5][6] only: No transfer of this Certificate
shall be made to any person unless the Transferee provides a certification
pursuant to Section 6.02(b) of the Agreement.]

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration

                                     A-4-5

of transfer, but the Trustee may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith. The
Depositor, the Trustee and any agent of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and none of the Depositor, the Trustee or any such agent shall be affected by
notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group I Certificates (other than the obligations to make payments to the related
Certificateholders) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Group I Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group I
Mortgage Loan and (B) the remittance of all funds due under the Agreement with
respect to the Group I Mortgage Loans, or (ii) the optional repurchase by the
party named in the Agreement of all the Group I Mortgage Loans and other assets
of the Trust Fund relating to the Group I Mortgage Loans in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date in which the aggregate Stated Principal Balance of the
Group I Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group I Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group I Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                                 SERIES 2005-AP1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class II-M-[1][2][3] Certificates with respect to a
         Trust Fund consisting primarily of a pool of conventional one- to
         four-family fixed interest rate mortgage loans sold by NOMURA ASSET
         ACCEPTANCE CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as a servicer, and Wells Fargo Bank, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the calendar
month preceding the calendar month in which the related Distribution Date occurs
on the Certificate Principal Balance hereof at a per annum rate equal to ____%
with respect to any Distribution Date which occurs on or prior to the related
Optional Termination Date, and (ii) [___]% per annum with respect to each
Distribution Date which occurs thereafter, in each case, subject to a cap equal
to the Net WAC Rate Cap for such Distribution Date.] The Trustee will distribute
on the 25th day of each month,

                                     A-5-2
<PAGE>

or, if such 25th day is not a Business Day, the immediately following Business
Day (each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last day (or if such last day is not a Business
Day, the Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Group II Mortgage Loan and is not likely
to be the date on which the Certificate Principal Balance of this Class of
Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the

<PAGE>

Trustee duly executed by the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates in authorized
denominations representing a like aggregate Percentage Interest will be issued
to the designated transferee.

                  Any transferee of this Certificate shall be deemed to make the
representations set forth in Section 6.02(b) of the Agreement.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group II Certificates (other than the obligations to make payments to the
related Certificateholders) shall terminate upon the earlier of (i) the later of
(A) the maturity or other liquidation (or Advance with respect thereto) of the
last Group II Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group
II Mortgage Loan and (B) the remittance of all funds due under the Agreement
with respect to the Group II Mortgage Loans, or (ii) the optional repurchase by
the party named in the Agreement of all the Group II Mortgage Loans and other
assets of the Trust Fund relating to the Group II Mortgage Loans in accordance
with the terms of the Agreement. Such optional repurchase may be made only on or
after the Distribution Date in which the aggregate Stated Principal Balance of
the Group II Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group II Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group II Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                                 SERIES 2005-AP1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class II-C Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee referred to below or any of their
affiliates or any other person. Neither this Certificate nor the underlying
Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC
or the Trustee or any of their affiliates or any other person. None of NAAC, the
Trustee or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

                  This certifies that Nomura Securities International, Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, fixed rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as depositor (the
"Depositor"), the Seller, as seller, GMAC Mortgage Corporation, as a servicer,
and Wells Fargo Bank, National Association, as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein,

                                     A-6-2
<PAGE>

capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate as set forth in the Agreement. The Trustee will distribute on
the 25th day of each month, or, if such 25th day is not a Business Day, the
immediately following Business Day (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last day (or if such
last day is not a Business Day, the Business Day immediately preceding such last
day) of the calendar month immediately preceding the month in which the
Distribution Date occurs, an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to the Holders of Certificates of the same Class as this Certificate. The
Assumed Final Distribution Date is the Distribution Date in the month following
the latest scheduled maturity date of any Mortgage Loan.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate shall be made to any person
unless the Transferee

                                     A-6-3
<PAGE>

provides a certification pursuant to Section 6.02(b) of the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group II Certificates (other than the obligations to make payments to the
related Certificateholders) shall terminate

                                     A-6-4

<PAGE>

upon the earlier of (i) the later of (A) the maturity or other liquidation (or
Advance with respect thereto) of the last Group II Mortgage Loan remaining in
the Trust Fund and disposition of all property acquired upon foreclosure or deed
in lieu of foreclosure of any Group II Mortgage Loan and (B) the remittance of
all funds due under the Agreement with respect to the Group II Mortgage Loans,
or (ii) the optional repurchase by the party named in the Agreement of all the
Group II Mortgage Loans and other assets of the Trust Fund relating to the Group
II Mortgage Loans in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date in which the
aggregate Stated Principal Balance of the Group II Mortgage Loans is less than
the percentage of the aggregate Stated Principal Balance specified in the
Agreement of the Group II Mortgage Loans at the Cut-off Date. The exercise of
such right will effect the early retirement of the Group II Certificates. In no
event, however, will the Trust Fund created by the Agreement continue beyond the
earlier of (i) the expiration of 21 years after the death of certain persons
identified in the Agreement and (ii) the Last Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class I-P Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee referred to below or any of their
affiliates or any other person. Neither this Certificate nor the underlying
Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC
or the Trustee or any of their affiliates or any other person. None of NAAC, the
Trustee or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

                  This certifies that Nomura Securities International, Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, fixed rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as depositor (the
"Depositor"), the Seller, as seller, GMAC Mortgage Corporation, as a servicer,

and Wells Fargo Bank, National Association, as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate shall be made to any person
unless the Transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group I Certificates (other than the obligations to make payments to the related
Certificateholders) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Group I Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group I
Mortgage Loan and (B) the remittance of all funds due under the Agreement with
respect to the Group I Mortgage Loans, or (ii) the optional repurchase by the
party named in the Agreement of all the Group I Mortgage Loans and other assets
of the Trust Fund relating to the Group I Mortgage Loans in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date in which the aggregate Stated Principal Balance of the
Group I Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group I Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group I Certificates. In no event, however, will

                                     A-7-4

the Trust Fund created by the Agreement continue beyond the earlier of (i) the
expiration of 21 years after the death of certain persons identified in the
Agreement and (ii) the Last Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group II Certificates (other than the obligations to make payments to the
related Certificateholders) shall terminate upon the earlier of (i) the later of
(A) the maturity or other liquidation (or Advance with respect thereto) of the
last Group II Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group
II Mortgage Loan and (B) the remittance of all funds due under the Agreement
with respect to the Group II Mortgage Loans, or (ii) the optional repurchase by
the party named in the Agreement of all the Group II Mortgage Loans and other
assets of the Trust Fund relating to the Group II Mortgage Loans in accordance
with the terms of the Agreement. Such optional repurchase may be made only on or
after the Distribution Date in which the aggregate Stated Principal Balance of
the Group II Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group II Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group II Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                                 SERIES 2005-AP1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [I][II]-R Certificates with respect to a Trust
         Fund consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee referred to below or any of their
affiliates or any other person. Neither this Certificate nor the underlying
Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC
or the Trustee or any of their affiliates or any other person. None of NAAC, the
Trustee or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

                  This certifies that Nomura Securities International, Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, fixed rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as depositor (the
"Depositor"), the Seller, as seller, GMAC Mortgage Corporation, as a servicer,
and Wells Fargo Bank, National Association, as trustee (the "Trustee"), a
summary of certain of

                                     A-9-3
<PAGE>

the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, capitalized terms used herein shall have the meaning ascribed to
them in the Agreement. This Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Depositor will have the right, in
its sole discretion and without notice to the Holder of this Certificate, to
sell this Certificate to a purchaser selected by the Depositor, which purchaser
may be the Depositor, or any affiliate of the Depositor, on such terms and
conditions as the Depositor may choose.

                  The Trustee will distribute on the 25th day of each month, or,
if such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last day (or if such last day is not a Business
Day, the Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amounts required to be distributed to the Holders of Certificates of the
same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month following the latest scheduled maturity date of
any Mortgage Loan.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or

                                     A-9-4
<PAGE>

qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate shall be made to any person
unless the Transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                                     A-9-5
<PAGE>

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Trustee or any such agent shall be affected
by notice to the contrary.

                  The obligations created by the Agreement with respect to the
Group [I][II] Certificates (other than the obligations to make payments to the
related Certificateholders) shall terminate upon the earlier of (i) the later of
(A) the maturity or other liquidation (or Advance with respect thereto) of the
last Group [I][II] Mortgage Loan remaining in the Trust Fund and disposition of
all property acquired upon foreclosure or deed in lieu of foreclosure of any
Group [I][II] Mortgage Loan and (B) the remittance of all funds due under the
Agreement with respect to the Group [I][II] Mortgage Loans, or (ii) the optional
repurchase by the party named in the Agreement of all the Group [I][II] Mortgage
Loans and other assets of the Trust Fund relating to the Group [I][II] Mortgage
Loans in accordance with the terms of the Agreement. Such optional repurchase
may be made only on or after the Distribution Date in which the aggregate Stated
Principal Balance of the Group [I][II] Mortgage Loans is less than the
percentage of the aggregate Stated Principal Balance specified in the Agreement
of the Group [I][II] Mortgage Loans at the Cut-off Date. The exercise of such
right will effect the early retirement of the Group [I][II] Certificates. In no
event, however, will the Trust Fund created by the Agreement continue beyond the
earlier of (i) the expiration of 21 years after the death of certain persons
identified in the Agreement and (ii) the Last Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                        MORTGAGE PASS-THROUGH CERTIFICATE
                                 SERIES 2005-AP1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class I-X Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Nomura Securities International Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, fixed rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as depositor (the
"Depositor"), the Seller, as seller, GMAC Mortgage Corporation, as a servicer,
and Wells Fargo Bank, National Association, as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Notional Balance hereof at a per annum rate equal to 0.01%.
The Trustee will distribute on the 25th day of each month, or, if such 25th day
is not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last day (or if such last day is not a Business Day, the
Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amount of interest required to be distributed to the Holders of
Certificates of the same Class as this Certificate.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon

                                     A-10-2
<PAGE>

presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose and designated in such notice. The initial
Certificate Notional Balance of this Certificate is set forth above.

         No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.]

                  No transfer of this Certificate shall be made to any person
unless the Transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.]

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in

                                     A-10-3
<PAGE>

certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Trustee or any such agent shall be affected
by notice to the contrary.

         The obligations created by the Agreement with respect to the Group I
Certificates (other than the obligations to make payments to the related
Certificateholders) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Group I Mortgage Loan remaining in the Trust Fund and disposition of all
property acquired upon foreclosure or deed in lieu of foreclosure of any Group I
Mortgage Loan and (B) the remittance of all funds due under the Agreement with
respect to the Group I Mortgage Loans, or (ii) the optional repurchase by the
party named in the Agreement of all the Group I Mortgage Loans and other assets
of the Trust Fund relating to the Group I Mortgage Loans in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date in which the aggregate Stated Principal Balance of the
Group I Mortgage Loans is less than the percentage of the aggregate Stated
Principal Balance specified in the Agreement of the Group I Mortgage Loans at
the Cut-off Date. The exercise of such right will effect the early retirement of
the Group I Certificates. In no event, however, will the Trust Fund created by
the Agreement continue beyond the earlier of (i) the expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the Last
Scheduled Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                           other similar security from any person in any manner,
                           (c) otherwise approach or negotiate with respect to

                           (e) above) would constitute a distribution of any
                           Certificate under the Act, that would render the
                           disposition of any Certificate a violation of Section
                           5 of the Act or any state securities law, or that
                           would require registration or qualification pursuant

Dear Ladies and Gentlemen:

         In connection with our purchase of Private Certificates, we confirm
that:

                  (i)      we understand that the Private Certificates are not
                           being registered under the Securities Act of 1933, as
                           amended (the "Act") or any applicable state
                           securities or "Blue Sky" laws, and are being sold to
                           us in a transaction that is exempt from the
                           registration requirements of such laws;

                  (ii)     any information we desired concerning the
                           Certificates, including the Private Certificates, the
                           trust in which the Certificates represent the entire
                           beneficial ownership interest (the "Trust") or any
                           other matter we deemed relevant to our decision to

                           to us;

                  (iii)    we are able to bear the economic risk of investment
                           in Private Certificates; we are an institutional
                           "accredited investor" as defined in Section 501(a) of
                           Regulation D promulgated under the Act and a
                           sophisticated institutional investor and we agree to
                           obtain a representation from any transferee that such
                           transferee is an institutional "accredited investor"
                           so long as we are required to obtain a representation
                           letter regarding compliance with the Act;

                  (iv)     we are acquiring Private Certificates for our own
                           account, not as nominee for any other person, and not
                           with a present view to any distribution or other
                           disposition of the Private Certificates;

                  (v)      we agree the Private Certificates must be held
                           indefinitely by us (and may not be sold, pledged,
                           hypothecated or in any way disposed of) unless
                           subsequently registered under the Act and any

                           we wish to dispose of or exchange any of the Private
                           Certificates (such disposition or exchange not being
                           currently foreseen or contemplated), we will not

APPENDIX E - STANDARD & POOR'S ANTI-PREDATORY LENDING CATEGORIZATION

Standard & Poor's has categorized loans governed by anti-predatory lending laws
in the Jurisdictions listed below into three categories based upon a combination
of factors that include (a) the risk exposure associated with the assignee
liability and (b) the tests and thresholds set forth in those laws. Note that
certain loans classified by the relevant statute as Covered are included in
Standard & Poor's High Cost Loan Category because they included thresholds and
tests that are typical of what is generally considered High Cost by the
industry.

NOMURA ASSET ACCEPTANCE CORPORATION, a Delaware corporation, as depositor (the
"Depositor"), NOMURA CREDIT & CAPITAL, INC., a Delaware corporation, as seller
(in such capacity, the "Seller"), GMAC MORTGAGE CORPORATION, a Pennsylvania

national banking association, not in its individual capacity, but solely as
trustee (the "Trustee") and as custodian (the "Custodian").

                              PRELIMINARY STATEMENT

         The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates.

                                     REMIC I
                                     -------

         As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement as a real estate mortgage investment
conduit (a "REMIC") for federal income tax purposes, and such segregated pool of
assets will be designated as "REMIC I." The R-I Interest will represent the sole
class of "residual interests" in REMIC I for purposes of the REMIC Provisions
(as defined herein) under federal income tax law. The following table
irrevocably sets forth the designation, the Uncertificated REMIC I Pass-Through
Rate, the Initial Uncertificated Principal Balance, and for purposes of

         The Seller has entered into this Agreement in consideration for the
purchase of the Mortgage Loans by the Depositor and has agreed to take the
actions specified herein.

         The Depositor, concurrently with the execution and delivery hereof,
hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee
for the use and benefit of the Certificateholders, without recourse, all the
right, title and interest of the Depositor in and to the Trust Fund.

         In connection with such sale, the Depositor has delivered to, and
deposited with, the Trustee or the Custodian, as its agent, the following
documents or instruments with respect to each Mortgage Loan so assigned: (i) the
original Mortgage Note, including any riders thereto, endorsed without recourse
to the order of "JPMorgan Chase Bank, N.A., as Trustee for certificateholders of
Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series
2005-AR1," and showing to the extent available to the Seller an unbroken chain
of endorsements from the original payee thereof to the Person endorsing it to
the Trustee, (ii) the original Mortgage and, if the related Mortgage Loan is a
MOM Loan, noting the presence of the MIN and language indicating that such
Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original
is not available, a copy), with evidence of such recording indicated thereon (or
if clause (x) in the proviso below applies, shall be in recordable form), (iii)
unless the Mortgage Loan is a MOM Loan, the assignment (either an original or a
copy, which may be in the form of a blanket assignment if permitted in the
jurisdiction in which the Mortgaged Property is located) to the Trustee of the
Mortgage with respect to each Mortgage Loan in the name of "JPMorgan Chase Bank,
N.A., as Trustee for certificateholders of Nomura Asset Acceptance Corporation,
Mortgage Pass-Through Certificates, Series 2005-AR1," which shall have been
recorded (or if clause (x) in the proviso below applies, shall be in recordable
form), (iv) an original or a copy of all intervening assignments of the
Mortgage, if any, to the extent available to the Seller, with evidence of
recording thereon, (v) the original policy of title insurance or mortgagee's
certificate of title insurance or commitment or binder for title insurance, if
available, or a copy thereof, or, in the event that such original title
insurance policy is unavailable, a photocopy thereof, or in lieu thereof, a
current lien search on the related Mortgaged Property and (vi) originals or
copies of all available assumption, modification or substitution agreements, if
any; provided, however, that in lieu of the foregoing, the Seller may deliver
the following documents, under the circumstances set forth below: (x) if any
Mortgage, assignment thereof to the Trustee or intervening assignments thereof
have been delivered or are being delivered to recording offices for recording
and have not been returned in time to permit

                                      -44-

with a certification by the Seller or the title company issuing the commitment
for title insurance, on the face of such copy, substantially as follows:
"Certified to be a true and correct copy of the original, which has been
transmitted for recording"; and (y) in lieu of the Mortgage Notes relating to
the Mortgage Loans identified in the list set forth in Exhibit J, the Depositor
may deliver a lost note affidavit and indemnity and a copy of the original note,
if available; and provided, further, that in the case of Mortgage Loans which
have been prepaid in full after the Cut-Off Date and prior to the Closing Date,
the Depositor, in lieu of delivering the above documents, may deliver to the
Trustee a certification of a Authorized Servicer Representative to such effect
and in such case shall deposit all amounts paid in respect of such Mortgage
Loans, in the Distribution Account on the Closing Date. In the case of the
documents referred to in clause (x) related above, the Depositor shall deliver
such documents to the Trustee promptly after they are received. The Seller shall
cause, at its expense, the Mortgage and intervening assignments, if any, and to
the extent required in accordance with the foregoing, the assignment of the
Mortgage to the Trustee to be submitted for recording promptly after the Closing
Date; provided that the Seller need not cause to be recorded any assignment (a)
in any jurisdiction under the laws of which, as evidenced by an Opinion of
Counsel delivered by the Seller to the Trustee and the Rating Agencies, the
recordation of such assignment is not necessary to protect the Trustee's
interest in the related Mortgage Loan or (b) if MERS is identified on the
Mortgage or on a properly recorded assignment of the Mortgage as mortgagee of
record solely as nominee for Seller and its successors and assigns. In the event
that the Seller or the Depositor gives written notice to the Trustee that a
court has recharacterized the sale of the Mortgage Loans as a financing, the
Seller shall submit or cause to be submitted for recording as specified above
or, should the Seller fail to perform such obligations, the Trustee shall cause
each such previously unrecorded assignment to be submitted for recording as
specified above at the expense of the Trust pursuant to Section 9.05. In the
event a Mortgage File is released to the Servicer as a result of such Person
having completed a Request for Release, the Trustee shall, if not so completed,
complete the assignment of the related Mortgage in the manner specified in
clause (iii) above.

         In connection with the assignment of any Mortgage Loan registered on
the MERS(R) System, the Seller further agrees that it will cause, at the
Seller's own expense, within 30 days after the Closing Date, the MERS(R) System
to indicate that such Mortgage Loans have been assigned by the Seller to the
Depositor and by the Depositor to the Trustee in accordance with this Agreement
for the benefit of the related Certificateholders by including (or deleting, in
the case of Mortgage Loans which are repurchased in accordance with this
Agreement) in such computer files (a) the code in the field which identifies the
specific Trustee and (b) the code in the field "Pool Field" which identifies the
series of the Certificates issued in connection with such Mortgage Loans. The
Seller further agrees that it will not, and will not permit any Servicer to
alter the codes referenced in this paragraph with respect to any Mortgage Loan
during the term of this Agreement unless and until such Mortgage Loan is
repurchased in accordance with the terms of this Agreement.

below, the documents (or certified copies thereof) delivered

                                      -45-
<PAGE>

to the Trustee or the Custodian on its behalf pursuant to Section 2.01 and
declares that it holds and will continue to hold directly or through a custodian
those documents and any amendments, replacements or supplements thereto and all
other assets of the Trust Fund delivered to it in trust for the use and benefit
of all present and future Holders of the Certificates. On the Closing Date, the
Custodian on the Trustee's behalf will deliver an Initial Certification in the
form annexed hereto as Exhibit C-1, confirming whether or not it has received
the Mortgage File for each Mortgage Loan, but without review of such Mortgage
File, except to the extent necessary to confirm whether such Mortgage File
contains the original Mortgage Note or a lost note affidavit and indemnity in
lieu thereof. No later than 90 days after the Closing Date, the Custodian on the
Trustee's behalf shall, for the benefit of the Certificateholders, review each
Mortgage File delivered to it and execute and deliver to the Seller and the
Trustee an Interim Certification substantially in the form annexed hereto as
Exhibit C-2. In conducting such review, the Custodian on the Trustee's behalf
will ascertain whether all required documents have been executed and received
and whether those documents relate, determined on the basis of the Mortgagor
name, original principal balance and loan number, to the Mortgage Loans
identified in Exhibit B to this Agreement, as supplemented (provided, however,
that with respect to those documents described in subclauses (iv) and (vi) of
Section 2.01, such obligations shall extend only to documents actually delivered
pursuant to such subclauses). In performing any such review, the Custodian may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon. If the
Custodian finds any document constituting part of the Mortgage File not to have
been executed or received, or to be unrelated to the Mortgage Loans identified
in Exhibit B, determined on the basis of the Mortgagor's name, the original
principal balance and the Mortgage Loan number, or to appear to be defective on
its face, the Custodian shall include such information in the exception report
attached to the Interim Certification. The Seller shall correct or cure any such
defect or, if prior to the end of the second anniversary of the Closing Date,
the Seller may substitute for the related Mortgage Loan a Replacement Mortgage
Loan, which substitution shall be accomplished in the manner and subject to the
conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion
of Counsel to the effect that such defect does not materially or adversely
affect the interests of the Certificateholders in such Mortgage Loan within 60
days from the date of notice from the Trustee of the defect and if the Seller
fails to correct or cure the defect or deliver such opinion within such period,
the Seller will, subject to Section 2.03, within 90 days from the notification
of the Trustee purchase such Mortgage Loan at the Purchase Price; provided,
however, that if such defect relates solely to the inability of the Seller to
deliver the Mortgage, assignment thereof to the Trustee, or intervening
assignments thereof with evidence of recording thereon because such documents
have been submitted for recording and have not been returned by the applicable
jurisdiction, the Seller shall not be required to purchase such Mortgage Loan if
the Seller delivers such documents promptly upon receipt, but in no event later
than 360 days after the Closing Date.

         (b) No later than 180 days after the Closing Date, the Custodian on the
Trustee's behalf will review, for the benefit of the Certificateholders, the
Mortgage Files and will execute and deliver or cause to be executed and
delivered to the Seller and the Trustee, a Final Certification substantially in
the form annexed hereto as Exhibit C-3. In conducting such review, the Custodian
on the Trustee's behalf will ascertain whether each document required to be
recorded has been returned from the recording office with evidence of recording
thereon and the Custodian on the Trustee's behalf has received either an
original or a copy thereof, as required

                                      -46-
<PAGE>

in Section 2.01 (provided, however, that with respect to those documents
described in subclauses (iv) and (vi) of Section 2.01, such obligations shall
extend only to documents actually delivered pursuant to such subclauses). If the
Custodian finds any document with respect to a Mortgage Loan has not been
received, or to be unrelated, determined on the basis of the Mortgagor name,
original principal balance and loan number, to the Mortgage Loans identified in
Exhibit B or to appear defective on its face, the Custodian shall note such
defect in the exception report attached to the Final Certification and the
Trustee shall promptly notify the Seller. The Seller shall correct or cure any
such defect or, if prior to the end of the second anniversary of the Closing
Date, the Seller may substitute for the related Mortgage Loan a Replacement
Mortgage Loan, which substitution shall be accomplished in the manner and
subject to the conditions set forth in Section 2.03 or shall deliver to the
Trustee an Opinion of Counsel to the effect that such defect does not materially
or adversely affect the interests of Certificateholders in such Mortgage Loan
within 60 days from the date of notice from the Trustee of the defect and if the
Seller is unable within such period to correct or cure such defect, or to
substitute the related Mortgage Loan with a Replacement Mortgage Loan or to
deliver such opinion, the Seller shall, subject to Section 2.03, within 90 days
from the notification of the Trustee, purchase such Mortgage Loan at the
Purchase Price; provided, however, that if such defect relates solely to the
inability of the Seller to deliver the Mortgage, assignment thereof to the
Trustee or intervening assignments thereof with evidence of recording thereon,
because such documents have not been returned by the applicable jurisdiction,
the Seller shall not be required to purchase such Mortgage Loan, if the Seller
delivers such documents promptly upon receipt, but in no event later than 360
days after the Closing Date.

         (c) In the event that a Mortgage Loan is purchased by the Seller in
accordance with subsections 2.02(a) or (b) above or Section 2.03, the Seller
shall remit the applicable Purchase Price to the Trustee for deposit in the
Distribution Account and shall provide written notice to the Trustee detailing
the components of the Purchase Price, signed by an authorized officer. Upon
deposit of the Purchase Price in the Distribution Account and upon receipt of a
Request for Release with respect to such Mortgage Loan, the Trustee will release
to the Seller the related Mortgage File and the Trustee shall execute and
deliver all instruments of transfer or assignment, without recourse, furnished
to it by the Seller, as are necessary to vest in the Seller title to and rights
under the Mortgage Loan. Such purchase shall be deemed to have occurred on the
date on which the deposit into the Distribution Account was made. The Trustee
shall promptly notify the Rating Agencies of such repurchase. The obligation of
the Seller to cure, repurchase or substitute for any Mortgage Loan as to which a
defect in a constituent document exists shall be the sole remedies respecting
such defect available to the Certificateholders or to the Trustee on their
behalf. The Seller shall promptly reimburse the Trustee for any expenses
incurred by the Trustee in respect of enforcing the remedies for such breach.

         (d) The Seller shall deliver to the Trustee, and Trustee agrees to
accept the Mortgage Note and other documents constituting the Mortgage File with
respect to any Replacement Mortgage Loan, which the Custodian will review as
provided in subsections 2.02(a) and 2.02(b), provided, that the Closing Date
referred to therein shall instead be the date of delivery of the Mortgage File
with respect to each Replacement Mortgage Loan.

         for Fannie Mae or Freddie Mac and is a mortgagee approved by the

         threatened in writing, against it that would materially and adversely
         affect the execution, delivery or enforceability of this Agreement or
         its ability to service the Mortgage Loans or to perform any of its
         other obligations under this Agreement in accordance with the terms
         hereof.

                  (vi) No consent, approval, authorization or order of any court
         or governmental agency or body is required for its execution, delivery
         and performance of, or compliance with, this Agreement or the
         consummation of the transactions contemplated hereby, or if any such
         consent, approval, authorization or order is required, it has obtained
         the same.

                  (vii) The Servicer has accurately and fully reported, and will
         continue to accurately and fully report its borrower credit files to
         each of the credit repositories in a timely manner materially in

                  (ix) The Servicer will not waive any Prepayment Charge with
         respect to a Mortgage Loan unless it is waived in accordance with the

         (b) The Seller hereby represents and warrants to and covenants with,
the Depositor, the Servicer and the Trustee as follows, as of the Closing Date:

                  (i) The Seller is duly organized, validly existing and in good

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

                  (ii) The Seller has the full corporate power and authority to

         a legal, valid and binding obligation of the Seller, enforceable
         against the Seller in accordance with its terms, except that (a) the

                  (iii) The execution and delivery of this Agreement by the
         Seller, the sale of the Mortgage Loans by the Seller under this
         Agreement, the consummation of any other of the transactions
         contemplated by this Agreement, and the fulfillment of or compliance
         with the terms hereof are in the ordinary course of business of the

<PAGE>

                  (vii) The representations and warranties set forth in Section
         8 of the Mortgage Loan Purchase Agreement are true and correct as of
         the Closing Date.

                  (viii) No Mortgage Loan is subject to the Home Ownership and
         Equity Protection Act of 1994 or any comparable law and no Mortgage
         Loan is classified and/or defined as a "high cost", "covered", "high
         risk home" or "predatory" loan under any other state, federal or local
         law or regulation or ordinance (or a similarly classified loan using
         different terminology under a law imposing heightened regulatory
         scrutiny or additional legal liability for residential mortgage loans
         having high interest rates, points and/or fees).

                  (ix) No loan is a High Cost Loan or Covered Loan, as
         applicable (as such terms are defined in Appendix E of the Standard &
         Poor's Glossary For File Format For LEVELS(R) Version 5.6 Revised
         (attached hereto as Exhibit N.) and no Mortgage Loan originated on or
         after October 1, 2002 through March 6, 2003 is governed by the Georgia
         Fair Lending Act.

                  (x) Any and all requirements of any federal, state or local
         law including, without limitation, usury, truth in lending, real estate
         settlement procedures, consumer credit protection, equal credit
         opportunity, fair housing, predatory, abusive lending or disclosure
         laws applicable to the origination and servicing of the Mortgage Loans
         have been complied with in all material respects.

         (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(b)(viii), (ix) and (x) and
Section 8 of the Mortgage Loan Purchase Agreement that materially and adversely
affects the interests of the Certificateholders in any Mortgage Loan, the party
discovering such breach shall give prompt written notice thereof to the other
parties. The Seller hereby covenants with respect to the representations and
warranties set forth in Section 2.03(b)(viii), (ix) and (x) and Section 8 of the
Mortgage Loan Purchase Agreement, that within ninety (90) days of the discovery
of a breach of any representation or warranty set forth therein that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, it shall cure such breach in all material respects and, if such breach is
not so cured, (i) prior to the second anniversary of the Closing Date, remove
such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and
substitute in its place a Replacement Mortgage Loan, in the manner and subject
to the conditions set forth in this Section; or (ii) repurchase the affected
Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the
manner set forth below; provided that any such substitution pursuant to (i)
above or repurchase pursuant to (ii) above shall not be effected prior to the
delivery to the Trustee of an Opinion of Counsel if required by Section 2.05 and
any such substitution pursuant to (i) above shall not be effected prior to the
additional delivery to the Trustee of a Request for Release. The Seller shall
promptly reimburse the Trustee for any expenses reasonably incurred by the
Trustee in respect of enforcing the remedies for such breach. To enable the
Servicer to amend the Mortgage Loan Schedule, the Seller shall, unless it cures
such breach in a timely fashion pursuant to this Section 2.03, promptly notify
the Trustee whether it intends either to repurchase, or to substitute for, the
Mortgage Loan affected by such breach. With respect to the representations and
warranties in Section 8 of the Mortgage Loan Purchase Agreement that are made to
the best of the Seller's knowledge, if it is discovered by any of the Depositor,
the Seller

                                      -51-
<PAGE>

or the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan, notwithstanding the Seller's lack of knowledge with
respect to the substance of such representation or warranty, the Seller shall
nevertheless be required to cure, substitute for or repurchase the affected
Mortgage Loan in accordance with the foregoing.

         With respect to any Replacement Mortgage Loan or Loans, the Seller
shall deliver to the Trustee for the benefit of the related Certificateholders
such documents and agreements as are required by Section 2.01. No substitution
will be made in any calendar month after the Determination Date for such month.
Scheduled Payments due with respect to Replacement Mortgage Loans in the Due
Period related to the Distribution Date on which such proceeds are to be
distributed shall not be part of the Trust Fund and will be retained by the
Seller. For the month of substitution, distributions to Certificateholders will
include the Scheduled Payment due on any Deleted Mortgage Loan for the related
Due Period and thereafter the Seller shall be entitled to retain all amounts
received in respect of such Deleted Mortgage Loan. The Servicer shall amend the
Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the
removal of such Deleted Mortgage Loan and the substitution of the Replacement
Mortgage Loan or Loans and shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Replacement Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the Seller
shall be deemed to have made with respect to such Replacement Mortgage Loan or
Loans, as of the date of substitution, the representations and warranties set
forth in Section 8 of the Mortgage Loan Purchase Agreement with respect to such
Mortgage Loan. Upon any such substitution and the deposit into the Distribution
Account of the amount required to be deposited therein in connection with such
substitution as described in the following paragraph and receipt by the Trustee
of a Request for Release for such Mortgage Loan, the Trustee shall release to
the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for
the benefit of the related Certificateholders and shall execute and deliver at
the Seller's direction such instruments of transfer or assignment as have been
prepared by the Seller, in each case without recourse, as shall be necessary to
vest in the Seller, or its respective designee, title to the Trustee's interest
in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03. The
Trustee shall not have any further responsibility with regard to such Mortgage
File.

         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for a Deleted Mortgage Loan, the Trustee will determine the
amount (if any) by which the aggregate principal balance of all the Replacement
Mortgage Loans as of the date of substitution is less than the Stated Principal
Balance (after application of the principal portion of the Scheduled Payment due
in the month of substitution) of such Deleted Mortgage Loan. An amount equal to
the aggregate of such deficiencies, described in the preceding sentence for any
Distribution Date (such amount, the "Substitution Adjustment Amount") shall be
remitted to the Servicer for deposit in the Custodial Account, by the Seller
delivering such Replacement Mortgage Loan on or before the Determination Date
for the Distribution Date relating to the Prepayment Period during which the
related Mortgage Loan was required to be purchased or replaced hereunder.

         In the event that the Seller shall be required to repurchase a Mortgage
Loan, the Purchase Price therefor shall be remitted to the Servicer for deposit
in the Custodial Account, on or before

                                      -52-
<PAGE>

the Determination Date immediately following the date on which the Seller was
required to repurchase such Mortgage Loan. The Purchase Price shall be remitted
by the Servicer to the Trustee on the Remittance Date occurring in the month
immediately following the month in which the Purchase Price was deposited in the
Custodial Account. In addition, upon such deposit of the Purchase Price, the
delivery of an Officer's Certificate by the Servicer to the Trustee certifying
that the Purchase Price has been deposited in the Custodial Account, the
delivery of an Opinion of Counsel if required by Section 2.05 and the receipt of
a Request for Release, the Trustee shall release the related Mortgage File held
for the benefit of the related Certificateholders to the Seller, and the Trustee
shall execute and deliver at such Person's direction the related instruments of
transfer or assignment prepared by the Seller, in each case without recourse, as
shall be necessary to transfer title from the Trustee for the benefit of the
Certificateholders and transfer the Trustee's interest to the Seller to any
Mortgage Loan purchased pursuant to this Section 2.03. It is understood and
agreed that the obligation under this Agreement of the Seller to cure,
repurchase or replace any Mortgage Loan as to which a breach has occurred and is
continuing shall constitute the sole remedies against the Seller respecting such
breach available to Certificateholders, the Depositor or the Trustee.

         (d) The representations and warranties set forth in Section 2.03 shall
survive delivery of the respective Mortgage Loans and Mortgage Files to the
Trustee or the Custodian for the benefit of the Certificateholders.

         Section 2.04 REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR.

         The Depositor hereby represents and warrants to, and covenants, with
the Servicer, the Seller and the Trustee as follows, as of the date hereof and
as of the Closing Date:

                  (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.

                  (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 has duly authorized,
         by all necessary corporate action on its part, the execution, delivery
         and performance of this Agreement; and this Agreement, assuming the due
         authorization, execution and delivery hereof by the other parties
         hereto, constitutes a legal, valid and binding obligation of the
         Depositor, enforceable against the Depositor in accordance with its
         terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
         moratorium receivership and other similar laws relating to creditors'
         rights generally and (ii) the remedy of specific performance and
         injunctive and other forms of equitable relief may be subject to
         equitable defenses and to the discretion of the court before which any
         proceeding therefor may be brought and further subject to public policy
         with respect to indemnity and contribution under applicable securities
         law.

                  (iii) The execution and delivery of this Agreement by the
         Depositor, the consummation of the transactions contemplated by this
         Agreement, and the fulfillment of

                                      -53-
<PAGE>

         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 material breach, violation or
         acceleration of, or result in a material default under, the terms of
         any other material agreement or instrument to which the 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 or the ability of the Depositor to
         perform its obligations under this 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 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 as of the
Closing Date, following the transfer of the Mortgage Loans to it by the Seller,
the Depositor had good title to the Mortgage Loans and the related Mortgage
Notes were subject to no offsets, claims, defenses or counterclaims.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.04 shall survive delivery of the Mortgage Files to the
Trustee or the Custodian for the benefit of the Certificateholders. Upon
discovery by the Depositor, the Servicer or the Trustee of a breach of such
representations and warranties, the party discovering such breach shall give
prompt written notice to the others and to each Rating Agency.

         Section 2.05  DELIVERY OF OPINION OF COUNSEL IN CONNECTION WITH
                       SUBSTITUTIONS AND REPURCHASES.

         (a) Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan that is not in default or as to which default is
not imminent, no repurchase or substitution pursuant to Sections 2.02 or 2.03
shall be made unless the Seller delivers to the Trustee an Opinion of Counsel,
addressed to the Trustee, to the effect that such repurchase or substitution
would not (i) result in the imposition of the tax on "prohibited transactions"
of REMIC I or REMIC II or contributions after the Closing Date, as defined in
sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any
REMIC to fail to qualify as a REMIC at any time that any Certificates are
outstanding. Any Mortgage Loan as to which repurchase or

                                      -54-
<PAGE>

substitution was delayed pursuant to this paragraph shall be repurchased or the
substitution therefor shall occur (subject to compliance with Sections 2.02 or
2.03) upon the earlier of (a) the occurrence of a default or imminent default
with respect to such Mortgage Loan and (b) receipt by the Trustee of an Opinion
of Counsel to the effect that such repurchase or substitution, as applicable,
will not result in the events described in clause (i) or clause (ii) of the
preceding sentence.

         (b) Upon discovery by the Depositor or the Seller 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 and the Trustee. In connection therewith, the Seller, at the
its option, shall either (i) substitute, if the conditions in Section 2.03(c)
with respect to substitutions are satisfied, a Replacement Mortgage Loan for the
affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90
days of such discovery in the same manner as it would a Mortgage Loan for a
breach of representation or warranty contained in Section 2.03. The Trustee
shall reconvey to the Seller 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  ISSUANCE OF THE REMIC I REGULAR INTERESTS AND THE CLASS R
                       CERTIFICATES.

         The Trustee acknowledges the assignment to it of the Mortgage Loans and
the delivery to the Custodian on its behalf of the related Mortgage Files,
subject to the provisions of Section 2.01 and Section 2.02, together with the
assignment to it of all other assets included in REMIC I, the receipt of which
is hereby acknowledged. The interests evidenced by the Class R-I Interest,
together with the REMIC I Regular Interests, constitute the entire beneficial
ownership interest in REMIC I. The rights of the Holders of the Class R-I
Interest and REMIC I (as holder of the REMIC I Regular Interests) to receive
distributions from the proceeds of REMIC I in respect of the Class R-I Interest
and the REMIC I Regular Interests, respectively, and all ownership interests
evidenced or constituted by the Class R-I Interest and the REMIC I Regular
Interests, shall be as set forth in this Agreement.

         Section 2.07 CONVEYANCE OF THE REMIC I REGULAR INTERESTS .

         The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey to the Trustee,
without recourse all the right, title and interest of the Depositor in and to
the REMIC I Regular Interests for the benefit of the Class R-II Interest and
REMIC II (as holder of the REMIC I Regular Interests). The Trustee acknowledges
receipt of the REMIC I Regular Interests and declares that it holds and will
hold the same in trust for the exclusive use and benefit of all present and
future Holders of the Class R-II Interest and REMIC II (as holder of the REMIC I
Regular Interests). The rights of the Holder of the Class R-II Interest and
REMIC II (as holder of the REMIC I Regular Interests) to receive distributions
from the proceeds of REMIC II in respect of the Class R-II Interest and Regular
Certificates, respectively, and all ownership interests evidenced or constituted
by the Class R-II Interest and the Regular Certificates, shall be as set forth
in this Agreement. The Class R-II Interest and the Regular Certificates shall
constitute the entire beneficial ownership interest in REMIC II.

         Section 2.08 ISSUANCE OF RESIDUAL CERTIFICATES.

         The Trustee acknowledges the assignment to it of the REMIC I Regular
Interests and, concurrently therewith and in exchange therefor, pursuant to the
written request of the Depositor executed by an officer of the Depositor, the
Trustee has executed, authenticated and delivered to or upon the order of the
Depositor, the Class R Certificates in authorized denominations.

         Section 2.09 ESTABLISHMENT OF TRUST.

         The Depositor does hereby establish, pursuant to the further provisions
of this Agreement and the laws of the State of New York, an express trust to be
known, for convenience, as "Nomura Asset Acceptance Corporation, Alternative
Loan Trust, Series 2005-AR1" and does hereby appoint JPMorgan Chase Bank, N.A.,
as Trustee in accordance with the provisions of this Agreement.

                                  ARTICLE III

               ADMINISTRATION AND SERVICING OF THE MORTGAGE LOANS

         Section 3.01 THE SERVICER TO ACT AS SERVICER.

         The Servicer shall service and administer the Mortgage Loans on behalf
of the Trust and in the best interest of and for the benefit of the
Certificateholders (as determined by the Servicer in its reasonable judgment) in
accordance with the terms of this Agreement and the Mortgage Loans and to the
extent consistent with such terms and in accordance with and exercising the same
care in performing those practices that the Servicer customarily employs and
exercises in servicing and administering mortgage loans for its own account
(including, compliance with all applicable federal, state and local laws).

         To the extent consistent with the foregoing, the Servicer shall seek
the timely and complete recovery of principal and interest on the Mortgage Notes
related to the Mortgage Loans and shall waive a Prepayment Charge only under the
following circumstances: (i) such waiver is standard and customary in servicing
similar mortgage loans and (ii) either (A) such waiver is related to a default
or reasonably foreseeable default and would, in the reasonable judgment of the
Servicer, maximize recovery of total proceeds taking into account the value of
such Prepayment Charge and the related Mortgage Loan and, if such waiver is made
in connection with a refinancing of the related Mortgage Loan, such refinancing
is related to a default or a reasonably foreseeable default or (B) such waiver
is made in connection with a refinancing of the related Mortgage Loan unrelated
to a default or a reasonably foreseeable default where (x) the related Mortgagor
has stated to the Servicer an intention to refinance the related Mortgage Loan
and (y) the Servicer has concluded in its reasonable judgment that the waiver of
such Prepayment Charge would induce such Mortgagor to refinance with the
Servicer or (iii) the Servicer reasonably believes such Prepayment Charge is
unenforceable in accordance with applicable law or the collection of such
related Prepayment Charge would otherwise violate applicable law. If a
Prepayment Charge is waived as permitted by meeting both of the standards
described in clauses (i) and (ii)(B) above, then the Servicer is required to pay
the amount of such waived Prepayment Charge (the "Servicer Prepayment Charge
Payment Amount"), for the benefit of the Holders of the Class P Certificates, by
depositing such amount into the Custodial Account within 90 days of notice or
discovery of such waiver meeting the standard set forth in both clauses (i) and
(ii)(B) above; provided, however, that the Servicer shall not waive more than 5%
of the Prepayment Charges (by number of Prepayment Charges) set forth on the
Prepayment Charge Schedule in accordance with clauses (i) and (ii)(B) above.
Notwithstanding any other provisions of this Agreement, any payments made by the
Servicer in respect of any waived Prepayment Charges pursuant to clauses (i) and
(ii)(B) above and the preceding sentence shall be deemed to be paid outside of
the Trust Fund.

         Subject only to the above-described applicable servicing standards (the
"Accepted Servicing Practices") and the terms of this Agreement and of the
respective Mortgage Loans, the Servicer shall have full power and authority,
acting alone and/or through subservicers as provided in Section 3.03, 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

                                      -57-
<PAGE>

Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any related Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided herein), (iii) to collect any Insurance Proceeds and
other Liquidation Proceeds, and (iv) subject to Section 3.09, to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan.

         Without limiting the generality of the foregoing, the Servicer, in its
own name or in the name of the Trust, the Depositor or the Trustee, is hereby
authorized and empowered by the Trust, the Depositor and the Trustee, when the
Servicer believes it appropriate in its reasonable judgment, to execute and
deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any
of them, any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge and all other comparable instruments, with respect
to the Mortgage Loans, and with respect to the related Mortgaged Properties held
for the benefit of the Certificateholders. The Servicer shall prepare and
deliver to the Depositor and/or the Trustee such documents requiring execution
and delivery by any or all of them as are necessary or appropriate to enable the
Servicer to service and administer the Mortgage Loans. Upon receipt of such
documents, the Depositor and/or the Trustee shall execute such documents and
deliver them to the Servicer. In addition, the Trustee shall execute, at the
written request of the Servicer, and furnish to the Servicer any special or
limited powers of attorney agreeable to the Trustee and its counsel for each
county in which a Mortgaged Property is located and other documents necessary or
appropriate to enable the Servicer to carry out its servicing and administrative
duties hereunder, provided such limited powers of attorney or other documents
shall be prepared by the Servicer and submitted to the Trustee for review prior
to execution.

         In accordance with the standards of the first paragraph of this Section
3.01, 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 relating to the Mortgage Loans in order to preserve the lien on the
Mortgaged Property, which advances shall be reimbursable in the first instance
from related collections from the Mortgagors pursuant to Section 4.04, and
further as provided in Section 4.02. All costs incurred by the Servicer, if any,
in effecting the payments of such taxes and assessments on the related 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.

         Section 3.02 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS.

         (a) Except as otherwise provided in this Section 3.02, when any
Mortgaged Property has been or is about to be conveyed by the Mortgagor, the
Servicer shall to the extent that it has knowledge of such conveyance, enforce
any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent
permitted under applicable law and governmental regulations, but only to the
extent that such enforcement will not adversely affect or jeopardize coverage
under any Required Insurance Policy. Notwithstanding the foregoing, the Servicer
shall not be required to exercise such rights with respect to a Mortgage Loan if
the Person to whom the related Mortgaged Property has been conveyed or is
proposed to be conveyed satisfies the terms and conditions contained in the
Mortgage Note and Mortgage related thereto and the consent of the

                                      -58-
<PAGE>

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 3.02(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 related 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
3.02(b), is also authorized with the prior approval of the insurers under any
Required Insurance Policies to enter into a substitution of liability agreement
with such Person, pursuant to which the original Mortgagor is released from
liability and such Person is substituted as Mortgagor and becomes liable under
the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be
deemed to be in default under this Section 3.02(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 3.02(a), in any case in which a related
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the related Mortgage Loan, the Servicer shall
prepare and deliver or cause to be prepared and delivered to the Trustee for
signature and shall direct, in writing, the Trustee to execute the assumption
agreement with the Person to whom the Mortgaged Property is to be conveyed and
such modification agreement or supplement to the Mortgage Note or Mortgage or
other instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
(including, but not limited to, the Mortgage Rate, the amount of the Scheduled
Payment, the Index, Gross Margin, Periodic Rate Cap, Adjustment Date, Maximum
Mortgage Interest Rate or Minimum Mortgage Interest Rate and any other term
affecting the amount or timing of payment on the related Mortgage Loan) may be
changed. In addition, the substitute Mortgagor and the Mortgaged Property must
be acceptable to the Servicer in accordance with the servicing standard set
forth in Section 3.01. The Servicer shall notify the Trustee that any such
substitution or assumption agreement has been completed by forwarding to the
Trustee the original of such substitution or assumption agreement, which in the
case of the original shall be added to the related Mortgage File and shall, for
all purposes, be considered a part of such Mortgage File to the same extent as
all other documents and instruments constituting a part thereof. Any fee
collected by the Servicer for entering into an assumption or substitution of
liability agreement will be retained by the Servicer as additional servicing
compensation.

         Section 3.03 SUBSERVICERS.

         The Servicer shall perform all of its servicing responsibilities
hereunder or may cause a subservicer to perform any such servicing
responsibilities on its behalf, but the use by the

                                      -59-
<PAGE>

Servicer of a subservicer shall not release the Servicer from any of its
obligations hereunder with respect to the related Mortgage Loans. The Servicer
shall pay all fees of each of its subservicers from its own funds, and a
subservicer's fee shall not exceed the Servicing Fee payable to the Servicer
hereunder.

         At the cost and expense of the Servicer, without any right of
reimbursement from the Custodial Account, the Servicer shall be entitled to
terminate the rights and responsibilities of a subservicer and arrange for any
servicing responsibilities to be performed by a successor subservicer; provided,
however, that nothing contained herein shall be deemed to prevent or prohibit
the Servicer, at its option, from electing to service the related Mortgage Loans
itself. In the event that the Servicer's responsibilities and duties under this
Agreement are terminated pursuant to Section 8.03, the Servicer shall at its own
cost and expense terminate the rights and responsibilities of each subservicer
with respect to the Mortgage Loans effective as of the date of the Servicer's
termination. The Servicer shall pay all fees, expenses or penalties necessary in
order to terminate the rights and responsibilities of each subservicer from the
Servicer's own funds without reimbursement from the Trust Fund.

         Notwithstanding the foregoing, the Servicer shall not be relieved of
its obligations hereunder with respect to the Mortgage Loans and shall be
obligated to the same extent and under the same terms and conditions as if it
alone were servicing and administering the Mortgage Loans. The Servicer shall be
entitled to enter into an agreement with a subservicer for indemnification of
the Servicer by the subservicer and nothing contained in this Agreement shall be
deemed to limit or modify such indemnification.

         Any subservicing agreement and any other transactions or services
relating to the Mortgage Loans involving a subservicer shall be deemed to be
between such subservicer and the Servicer alone, and the Trustee shall not have
any obligations, duties or liabilities with respect to such subservicer
including any obligation, duty or liability of the Trustee to pay such
subservicer's fees and expenses or any differential in the amount of the
servicing fee paid hereunder and the amount necessary to induce any successor
servicer to act as successor servicer under this Agreement and the transactions
provided for in this Agreement. For purposes of remittances to the Trustee
pursuant to this Agreement, the Servicer shall be deemed to have received a
payment on a Mortgage Loan when a subservicer has received such payment.

         Section 3.04  DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF THE
                       SERVICER TO BE HELD FOR TRUSTEE.

         Notwithstanding any other provisions of this Agreement, the Servicer
shall transmit to the Trustee as required by this Agreement all documents and
instruments in respect of a related Mortgage Loan coming into the possession of
the Servicer from time to time and shall account fully to the Trustee for any
funds received by the Servicer or that otherwise are collected by the Servicer
as Liquidation Proceeds or Insurance Proceeds in respect of any such Mortgage
Loan. 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 Custodial Account, shall be held by
the Servicer for and on behalf of the Trustee and shall be and remain the sole
and exclusive property of the Trustee, subject to the applicable provisions of
this

                                      -60-
<PAGE>

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

         Section 3.05 MAINTENANCE OF HAZARD INSURANCE.

         (a) The Servicer shall cause to be maintained for each Mortgage Loan
hazard insurance with extended coverage on the Mortgaged Property in an amount
which is at least equal to the lesser of (i) the Stated Principal Balance of
such Mortgage Loan and (ii) the amount necessary to fully compensate for any
damage or loss to the improvements that are a part of such property on a
replacement cost basis, in each case in an amount not less than such amount as
is necessary to avoid the application of any coinsurance clause contained in the
related hazard insurance policy. The Servicer shall also cause to be maintained
hazard insurance with extended coverage on each REO Property in an amount which
is at least equal to the lesser of (i) the maximum insurable value of the
improvements which are a part of such REO Property and (ii) the Stated Principal
Balance of the related Mortgage Loan at the time it became an REO Property. The
Servicer will comply in the performance of this Agreement with all reasonable
rules and requirements of each insurer under any such hazard policies. Any
amounts collected by the Servicer under any such policies (other than amounts to
be applied to the restoration or repair of the property subject to the related
Mortgage or amounts to be released to the Mortgagor in accordance with the
procedures that the Servicer would follow in servicing loans held for its own
account, subject to the terms and conditions of the related Mortgage and
Mortgage Note and in accordance with the servicing standard set forth in Section
3.01) shall be deposited in the Custodial Account, subject to withdrawal
pursuant to Section 4.02. Any cost incurred by the Servicer in maintaining any
such insurance shall not, for the purpose of calculating distributions to
Certificateholders, be added to the Stated Principal Balance of the related
Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit.
It is understood and agreed that no earthquake or other additional insurance is
to be required of any Mortgagor 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 or REO Property is at any time
in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards and flood insurance has been
made available, the Servicer shall cause to be maintained a flood insurance
policy in respect thereof. Such flood insurance shall be in an amount equal to
the lesser of (i) the Stated Principal Balance of the related Mortgage Loan and
(ii) the maximum amount of such insurance available for the related Mortgaged
Property under the national flood insurance program (assuming that the area in
which such Mortgaged Property is located is participating in such program).

         In the event that the Servicer shall obtain and maintain a blanket
policy with an insurer having a General Policy Rating of B:VI or better in
Best's Key Rating Guide (or such other rating that is comparable to such rating)
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 two

                                      -61-
<PAGE>

sentences of this Section 3.05, it being understood and agreed that such policy
may contain a deductible clause, in which case the Servicer shall, in the event
that there shall not have been maintained on the related Mortgaged Property or
REO Property a policy complying with the first two sentences of this Section
3.05, and there shall have been one or more losses which would have been covered
by such policy, deposit to the Custodial Account from its own funds the amount
not otherwise payable under the blanket policy because of such deductible
clause. In connection with its activities as administrator and servicer of the
Mortgage Loans, the Servicer agrees to prepare and present, on behalf of itself,
the Trustee and Certificateholders, claims under any such blanket policy in a
timely fashion in accordance with the terms of such policy.

         (b) The Servicer shall keep in force during the term of this Agreement
a policy or policies of insurance covering errors and omissions for failure in
the performance of the Servicer's obligations under this Agreement, which policy
or policies shall be in such form and amount that would meet the requirements of
Fannie Mae or Freddie Mac if it were the purchaser of the related Mortgage
Loans, unless the Servicer has obtained a waiver of such requirements from
Fannie Mae or Freddie Mac. The Servicer shall provide the Trustee, upon request,
with copies of such insurance policies and fidelity bond. The Servicer shall
also maintain a fidelity bond in the form and amount that would meet the
requirements of Fannie Mae or Freddie Mac, unless the Servicer has obtained a
waiver of such requirements from Fannie Mae or Freddie Mac. The Servicer shall
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. Any such errors and omissions policy and fidelity bond shall by
its terms not be cancelable without thirty days' prior written notice to the
Trustee. The Servicer shall also cause its subservicers to maintain a policy of
insurance covering errors and omissions and a fidelity bond which would meet
such requirements.

         Section 3.06 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS.

         The Servicer shall prepare and present on behalf of the Trustee and the
Certificateholders all claims under the Insurance Policies and take such actions
(including the negotiation, settlement, compromise or enforcement of the
insured's claim) as shall be necessary to realize recovery under such Insurance
Policies. Any proceeds disbursed to the Servicer in respect of such Insurance
Policies shall, within two Business Days of its receipt, be deposited in the
Custodial Account upon receipt, except that any amounts realized that are to be
applied to the repair or restoration of the related Mortgaged Property as a
condition precedent to the presentation of claims on the related Mortgage Loan
to the insurer under any applicable Insurance Policy need not be so deposited
(or remitted).

         Section 3.07 MAINTENANCE OF INSURANCE POLICIES.

         The Servicer shall not take any action that would result in noncoverage
under any applicable Insurance Policy of any loss which, but for the actions of
the Servicer would have been covered thereunder. The Servicer shall use its best
efforts to keep in force and effect (to the extent that the related Mortgage
Loan requires the Mortgagor to maintain such insurance), any applicable
Insurance Policy. The Servicer shall not cancel or refuse to renew any Insurance

                                      -62-
<PAGE>

Policy that is in effect at the date of the initial issuance of the Mortgage
Note and is required to be kept in force hereunder.

         Section 3.09 REALIZATION UPON DEFAULTED MORTGAGE LOANS; DETERMINATION
                      OF EXCESS LIQUIDATION PROCEEDS AND REALIZED LOSSES;
                      REPURCHASES OF CERTAIN MORTGAGE LOANS.

         (a) The Servicer shall use reasonable efforts 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 that
the Servicer shall not be required to expend its own funds in connection with
any foreclosure or towards the restoration of any property unless it shall
determine (i) that such restoration and/or foreclosure will increase the
proceeds of liquidation of the related 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 Custodial Account pursuant to Section 4.02). If
the Servicer reasonably believes that Liquidation Proceeds with respect to any
such Mortgage Loan would not be increased as a result of such foreclosure or
other action, such Mortgage Loan will be charged-off and will become a
Liquidated Loan. The Servicer will give notice of any such charge-off to the
Trustee. The Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided that such costs and expenses
shall be Servicing Advances and that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 4.02. If the Servicer has knowledge that a Mortgaged
Property that the Servicer is contemplating acquiring in foreclosure or by
deed-in-lieu of foreclosure is located within a one-mile radius of any site with
environmental or hazardous waste risks known to the Servicer, the Servicer
shall, prior to acquiring the Mortgaged Property, consider such risks and only
take action in accordance with its established environmental review procedures.

         With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the Trustee for the benefit of the Certificateholders
(or the Trustee's nominee on behalf of the Certificateholders). The Trustee's
name shall be placed on the title to such REO Property solely as the Trustee
hereunder and not in its individual capacity. The Servicer shall ensure that the
title to such REO Property references this Agreement and the Trustee's capacity
hereunder. Pursuant to its efforts to sell such REO Property, the Servicer shall
either itself or through an agent selected by the Servicer protect and conserve
such REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Certificateholders, rent the
same, or any part thereof, as the Servicer deems to be in the best interest of
the Servicer and the Certificateholders for the period prior to the sale of such
REO Property. The Servicer shall prepare for and deliver to the Trustee a
statement with respect to each REO Property that has been rented showing the
aggregate rental income received and all expenses incurred in

                                      -63-
<PAGE>

connection with the management and maintenance of such REO Property at such
times as is necessary to enable the Trustee 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 Custodial Account no later than
the close of business on each Determination Date. The Servicer shall perform the
tax reporting and withholding related to foreclosures, abandonments and
cancellation of indebtedness income as specified by Sections 6050H, 6050J and
6050P of the Code by preparing and filing such tax and information returns, as
may be required.

         In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
three years after its acquisition by the Trust Fund or, at the expense of the
Trust Fund, request from the Internal Revenue Service 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. The Trustee shall be supplied with an Opinion of
Counsel (such opinion not to be an expense of the Trustee or the Trust Fund) to
the effect that the holding by the Trust Fund of such Mortgaged Property
subsequent to such three-year period will not result in the imposition of taxes
on "prohibited transactions" of any REMIC as defined in section 860F of the Code
or cause any REMIC to fail to qualify as a REMIC at any time that any
Certificates are outstanding, in which case the Trust Fund may continue to hold
such Mortgaged Property (subject to any conditions contained in such Opinion of
Counsel). Notwithstanding any other provision of this Agreement, no Mortgaged
Property acquired by the Trust Fund shall be rented (or allowed to continue to
be rented) or otherwise used for the production of income by or on behalf of the
Trust Fund in such a manner or pursuant to any terms that would (i) cause such
Mortgaged Property to fail to qualify as "foreclosure property" within the
meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC to the
imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under section 860G(c) of the Code or otherwise, unless
the Servicer has agreed to indemnify and hold harmless the Trust Fund with
respect to the imposition of any such taxes.

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

         The Liquidation Proceeds from any liquidation of a Mortgage Loan, net
of any payment to the Servicer as provided above, shall be deposited in the
Custodial Account on the next

                                      -64-
<PAGE>

succeeding Determination Date following receipt thereof for distribution on the
related Distribution Date, except that any Excess Liquidation Proceeds shall be
retained by the Servicer as additional servicing compensation.

         The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds or any income from an REO
Property, shall be applied in the following order of priority: first, to
reimburse the Servicer for any related unreimbursed Servicing Advances and
Servicing Fees, pursuant to Section 4.02 or this Section 3.09; second, to
reimburse the Servicer for any unreimbursed Advances, pursuant to Section 4.02
or this Section 3.09; third, to accrued and unpaid interest (to the extent no
Advance has been made for such amount) on the Mortgage Loan or related REO
Property, at the Net Mortgage Rate to the first day of 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 Liquidation Proceeds and Realized Losses,
if any, with respect to any Mortgage Loan for the related Prepayment Period.

         (c) The Servicer has no intent to foreclose on any Mortgage Loan based
on the delinquency characteristics as of the Closing Date; provided, however,
that the foregoing does not prevent the Servicer from initiating foreclosure
proceedings on any date hereafter if the facts and circumstances of such
Mortgage Loans including delinquency characteristics in the Servicer's
discretion so warrant such action.

         Section 3.10 SERVICING COMPENSATION.

         As compensation for its activities hereunder, the Servicer shall be
entitled to retain or withdraw from the Custodial Account out of each payment of
interest on each Mortgage Loan included in the Trust Fund an amount equal to the
Servicing Fee. In addition, the Servicer shall be entitled to recover unpaid
Servicing Fees out of Liquidation Proceeds, Insurance Proceeds or condemnation
proceeds to the extent permitted by Section 4.02.

         Additional servicing compensation with respect to Mortgage Loans in the
form of any Excess Liquidation Proceeds, assumption fees, late payment charges,
insufficient funds charges and ancillary income to the extent such fees or
charges are received by the Servicer, all income and gain net of any losses
realized from Permitted Investments with respect to funds in or credited to the
Custodial Account shall be retained by the Servicer to the extent not required
to be deposited in the Custodial Account pursuant to Section 4.02. 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 3.05 and maintenance of the other forms of
insurance coverage required by Section 3.07) and shall not be entitled to
reimbursement therefor except as specifically provided in Section 4.02.

         Section 3.11 REO PROPERTY.

         (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Mortgage Loan, the deed or certificate of sale shall
be issued to the Trustee, or to its nominee, on behalf of the related
Certificateholders. The Servicer shall sell any REO Property

                                      -65-
<PAGE>

as expeditiously as possible and in accordance with the provisions of this
Agreement. Pursuant to its efforts to sell such REO Property, the Servicer shall
protect and conserve such REO Property in the manner and to the extent required
herein, in accordance with the REMIC Provisions.

         (b) The Servicer shall deposit all funds collected and received in
connection with the operation of any REO Property into the Custodial Account.

         (c) The Servicer, upon the final disposition of any REO Property, shall
be entitled to reimbursement for any related unreimbursed Advances, unreimbursed
Servicing Advances or Servicing Fees from Liquidation Proceeds received in
connection with the final disposition of such REO Property; provided, that any
such unreimbursed Advances or Servicing Fees as well as any unpaid Servicing
Fees may be reimbursed or paid, as the case may be, prior to final disposition,
out of any net rental income or other net amounts derived from such REO
Property.

         Section 3.12 LIQUIDATION REPORTS.

         Upon the foreclosure of any Mortgaged Property or the acquisition
thereof by the Trust Fund pursuant to a deed-in-lieu of foreclosure, the
Servicer shall submit a liquidation report to the Trustee containing such
information as shall be mutually acceptable to the Servicer and the Trustee with
respect to such Mortgaged Property.

         Section 3.13 ANNUAL CERTIFICATE AS TO COMPLIANCE.

         (a) The Servicer shall deliver to the Depositor and the Trustee not
later than March 15th of each year commencing in 2006 (or, in each case, if such
day is not a Business Day, the immediately preceding Business Day), a
certificate of a Authorized Servicer Representative stating, as to each
signatory thereof, that (i) a review of the activities of the Servicer during
the preceding calendar year and of performance under this Agreement has been
made under such officers' supervision, and (ii) to the best of such officers'
knowledge, based on such review, the Servicer has fulfilled all of its
obligations under this Agreement throughout such year, or, if there has been a
default in the fulfillment of any such obligation, specifying each such default
known to such officers and the nature and status thereof except for such
defaults as such officer in its good faith judgment believes to be immaterial.

         (b) (i) The Servicer shall deliver to the Depositor and the Trustee, on
or before March 15th of each year commencing in 2006, a certification containing
the information set forth in Exhibit L. Such certification shall be signed by
the senior officer in charge of servicing of the Servicer. In addition, the
Servicer shall provide such other information with respect to the related
Mortgage Loans and the servicing and administration thereof within the control
of the Servicer which shall be required to enable the Depositor and the Trustee
to comply with the reporting requirements of the Securities and Exchange Act of
1934, as amended (the "Exchange Act").

                  (ii) The Servicer shall indemnify and hold harmless the
         Depositor, the Trustee and their respective officers, directors, agents
         and affiliates from and against any losses, damages, penalties, fines,
         forfeitures, reasonable legal fees and related costs, judgments and
         other costs and expenses to the extent arising out of or based upon a
         breach by the Servicer or any of its officers, directors, agents or
         affiliates of its obligations under this

                                      -66-
<PAGE>

         Section 3.13(b), or a breach in any of the representations in the
         certification delivered pursuant to clause (b)(i) above, or the
         Servicer's gross negligence, bad faith or willful misconduct in
         connection therewith. If the indemnification provided for herein is
         unavailable to the Depositor and the Trustee as a result of a court of
         law or other administrative or regulatory body with authority holding
         such indemnification void on the basis of public policy or similar
         reason, then the Servicer agrees that it shall contribute to the amount
         paid or payable by the Depositor and the Trustee as a result of the
         losses, claims, damages or liabilities of the Depositor or the Trustee
         in such proportion as is appropriate to reflect the relative fault of
         the Trustee or the Depositor on the one hand and the Servicer on the
         other in connection with a breach of the Servicer's obligations under
         this Section 3.13(b) or the Servicer's gross negligence, bad faith or
         willful misconduct in connection therewith or a breach of any of the
         representations in the certification delivered pursuant to clause
         (b)(i) above with respect to the matters covered by this Section
         3.13(b)(ii).

         Section 3.14 ANNUAL INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS' SERVICING
                      REPORT.

         Not later than March 15th of each year, commencing in 2006, the
Servicer, at its expense, shall cause a nationally recognized firm of
independent certified public accountants to furnish to the Servicer a report
stating that (i) it has obtained a letter of representation regarding certain
matters from the management of the Servicer which includes an assertion that the
Servicer has complied with certain minimum residential mortgage loan servicing
standards, identified in the Uniform Single Attestation Program for Mortgage
Bankers established by the Mortgage Bankers Association of America, with respect
to the servicing of residential mortgage loans during the most recently
completed fiscal or calendar year and (ii) on the basis of an examination
conducted by such firm in accordance with standards established by the American
Institute of Certified Public Accountants, such representation is fairly stated
in all material respects, subject to such exceptions and other qualifications
that may be appropriate. In rendering its report such firm may rely, as to
matters relating to the direct servicing of residential mortgage loans by
subservicers, upon comparable reports of firms of independent certified public
accountants rendered on the basis of examinations conducted in accordance with
the same standards (rendered within one year of such report) with respect to
those subservicers. Promptly upon receipt of such report, the Servicer shall
furnish a copy of such report to the Depositor, the Trustee and each Rating
Agency. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Servicer's expense, provided that such
statement is delivered by the Servicer to the Trustee.

         Section 3.15 BOOKS AND RECORDS.

         The Servicer shall be responsible for maintaining, and shall maintain,
a complete set of books and records for the related Mortgage Loans which shall
be appropriately identified in the Servicer's computer system to clearly reflect
the ownership of the related Mortgage Loans by the Trust. In particular, the
Servicer shall maintain in its possession, available for inspection by the
Trustee and shall deliver to the Trustee upon reasonable prior request and
during normal business hours, evidence of compliance with all federal, state and
local laws, rules and regulations. To the extent that original documents are not
required for purposes of realization of Liquidation Proceeds or Insurance
Proceeds, documents maintained by the Servicer may be in the form of

                                      -67-
<PAGE>

microfilm or microfiche or such other reliable means of recreating original
documents, including, but not limited to, optical imagery techniques so long as
the Servicer complies with the requirements of Accepted Servicing Practices.

         The Servicer shall maintain with respect to each related Mortgage Loan
and shall upon reasonable prior request and during normal business hours make
available for inspection by the Trustee the related servicing file during the
time such Mortgage Loan is subject to this Agreement and thereafter in
accordance with applicable law.

         Section 3.16 THE TRUSTEE.

         The Trustee shall furnish the Servicer with any powers of attorney and
other documents in form as mutually agreed upon and necessary or appropriate to
enable the Servicer to service and administer the Mortgage Loans and REO
Properties.

         The Trustee shall provide access to the records and documentation in
possession of the Trustee regarding the related Mortgage Loans and REO Property
and the 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 Trustee; provided, however, that, unless otherwise required by
law, the Trustee shall not 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 Trustee 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 Trustee's actual costs.

         The Trustee shall execute and deliver as directed in writing by the
Servicer any court pleadings, requests for trustee's sale or other documents
necessary or desirable to (i) the foreclosure or trustee's sale with respect to
a Mortgaged Property; (ii) any legal action brought to obtain judgment against
any Mortgagor on the Mortgage Note or Security Instrument; (iii) obtain a
deficiency judgment against the Mortgagor; or (iv) enforce any other rights or
remedies provided by the Mortgage Note or Security Instrument or otherwise
available at law or equity.

         Section 3.17 REMIC-RELATED COVENANTS.

         For as long as each REMIC shall exist, the Trustee shall act in
accordance herewith to assure continuing treatment of such REMIC as a REMIC, and
the Trustee shall comply with any directions of the Seller or the Servicer to
assure such continuing treatment. In particular, the Trustee shall not (a)
knowingly sell or permit the sale of all or any portion of the Mortgage Loans or
of any investment of deposits in an Account unless such sale is as a result of a
repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has
received a REMIC Opinion prepared at the expense of the Trust Fund; and (b)
other than with respect to a substitution pursuant to the Mortgage Loan Purchase
Agreement or Section 2.04 of this Agreement, as applicable, accept any
contribution to any REMIC after the Startup Day without receipt of a REMIC
Opinion.

                                      -68-
<PAGE>

         Section 3.18 REIMBURSEMENT OF COSTS AND EXPENSES.

         (a) To the extent that the costs and expenses of the Trustee related to
any termination of the Servicer, appointment of a Successor Servicer or the
transfer and assumption of servicing by the Trustee with respect to this
Agreement (including, without limitation, (i) all legal costs and expenses and
all due diligence costs and expenses associated with an evaluation of the
potential termination of the Servicer as a result of an event of default by such
Person and (ii) all costs and expenses associated with the complete transfer of
servicing, including all servicing files and all servicing data and the
completion, correction or manipulation of such servicing data as may be required
by the Successor Servicer to correct any errors or insufficiencies in the
servicing data or otherwise to enable the successor service to service the
related Mortgage Loans in accordance with this Agreement) are not fully and
timely reimbursed by the Servicer, the Trustee shall be entitled to
reimbursement of such costs and expenses from the Distribution Account.

         (b) If the Trustee acts as a Successor Servicer to the Servicer, it
will not assume liability for the representations and warranties of the Servicer
contained herein.

         Section 3.19 RELEASE OF MORTGAGE FILES.

         (a) Upon becoming aware of the payment in full of any Mortgage Loan, or
the receipt by the Servicer of a notification that payment in full has been
escrowed in a manner customary for such purposes for payment to the related
Certificateholders on the next Distribution Date, the Servicer will promptly
furnish to the Trustee and the Custodian, on behalf of the Trustee, two copies
of a certification substantially in the form of Exhibit H hereto signed by a
Authorized Servicer Representative or in a mutually agreeable electronic format
which will, in lieu of a signature on its face, originate from a Authorized
Servicer Representative (which certification shall include a statement to the
effect that all amounts received in connection with such payment that are
required to be deposited in the Custodial Account pursuant to Article V have
been or will be so deposited) and shall request that the Custodian, on behalf of
the Trustee, deliver to the Servicer the related Mortgage File. Within five (5)
Business Days of receipt of such certification and request, the Custodian, on
behalf of the Trustee, shall release the related Mortgage File to the Servicer
and the Trustee and Custodian shall have no further responsibility with regard
to such Mortgage File. Upon any such payment in full, the Servicer is
authorized, to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the related Mortgage Loan, an instrument of satisfaction
(or assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Custodial Account.

         (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with this Agreement, the
Trustee shall execute such documents as shall be prepared and furnished to the
Trustee by the Servicer (in form reasonably acceptable to the Trustee) and as
are necessary to the prosecution of any such proceedings. The Custodian, on
behalf of the Trustee, shall, upon the written request of the Servicer, and
delivery

                                      -69-
<PAGE>

to the Custodian, on behalf of the Trustee, of two copies of a request for
release signed by a Authorized Servicer Representative substantially in the form
of Exhibit H (or in a mutually agreeable electronic format which will, in lieu
of a signature on its face, originate from a Authorized Servicer
Representative), release the related Mortgage File held in its possession or
control to the Servicer. Such request for release shall obligate the Servicer to
return the Mortgage File to the Custodian on behalf of the Trustee, when the
need therefor by such Person no longer exists unless the Mortgage Loan shall be
liquidated, in which case, upon receipt of a certificate of a Authorized
Servicer Representative similar to that hereinabove specified, the Mortgage File
shall be released by the Custodian, on behalf of the Trustee, to the Servicer.

         Section 3.20  DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF THE
                       SERVICER TO BE HELD FOR TRUSTEE.

(a) The Servicer (to the extent required by this Agreement) shall transmit to
the Trustee or to Custodian such documents and instruments coming into the
possession of such Person from time to time as are required by the terms hereof
to be delivered to the Trustee or the Custodian. Any funds received by the
Servicer in respect of any Mortgage Loan or which otherwise are collected by the
Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any
Mortgage Loan shall be held for the benefit of the Trustee and the related
Certificateholders subject to the right of the Servicer to retain its Servicing
Fee and other amounts as provided in this Agreement.

         Section 3.21  POSSESSION OF CERTAIN INSURANCE POLICIES AND DOCUMENTS.

         The Servicer shall retain possession and custody of the originals (to
the extent available) of any 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, the
Trustee (or the Custodian, as directed by the Trustee) shall retain possession
and custody of each Mortgage File in accordance with and subject to the terms
and conditions of this Agreement.

         Section 3.22  ANNUAL CERTIFICATE AS TO COMPLIANCE.

         (a) The Depositor shall prepare and file or caused to be prepared and
filed the initial Form 8-K. Within 15 days after each Distribution Date, the
Trustee shall, in accordance with industry standards, file with the Commission
via the Electronic Data Gathering and Retrieval System ("EDGAR"), a Form 8-K
with a copy of the statement to be furnished by the Trustee to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2006, the Trustee shall, in accordance with industry standards, file
a Form 15 Suspension Notice with respect to the Trust Fund. Prior to March 30,
2006 and annually thereafter, if required, the Trustee shall, subject to
subsection (d) below, file a Form 10-K, in substance conforming to industry
standards, with respect to the Trust Fund. Such Form 10K shall be signed by the
Depositor and shall include, to the extent available, as exhibits (i) the
Servicer's annual statement of compliance described under Section 3.13 hereof,
(ii) the Servicer's accountants report described under Section 3.14 and (iii)
the Form 10-K certification signed by the Depositor. If items (i), (ii) and
(iii) in the preceding sentence are not timely delivered, the Trustee shall file
an amended Form 10-K including such documents as exhibits reasonably promptly
after they are

                                      -70-
<PAGE>

delivered to the Trustee. The Depositor hereby grants to the Trustee a limited
power of attorney to execute and file each Form 8-K and the Form 15 on behalf of
the Depositor. Such power of attorney shall continue until either the earlier of
(i) receipt by the Trustee from the Depositor of written termination of such
power of attorney and (ii) the termination of the Trust Fund. The Depositor
agrees to promptly furnish to the Trustee, from time to time upon request, such
further information, reports and financial statements within its control related
to this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file a Form 8-K and the Form 15 with the Commission.
The Trustee will reasonably cooperate with the Depositor in connection with any
additional filings with respect to the Trust Fund as the Depositor deems
necessary under the Exchange Act. Copies of all reports filed by the Trustee
under the Exchange Act shall be sent to the Depositor.

         (b) In connection with the filing of any 10-K hereunder, the Trustee
shall sign a certification (in the form attached hereto as Exhibit M) on behalf
of the Depositor regarding certain aspects of the Form 10-K certification signed
by the Depositor, provided, however, that the Trustee shall not be required to
undertake an analysis of any accountant's report attached as an exhibit to the
Form 10-K.

         (c) (i) The Trustee shall indemnify and hold harmless the Depositor and
its officers, directors and Affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments and other costs and expenses arising out of or based upon a
breach of the Trustee's obligations under this Section 3.22 or the Trustee's
negligence, bad faith or willful misconduct in connection therewith.

                  (ii) The Depositor shall indemnify and hold harmless the
         Trustee and its officers, directors and Affiliates from and against any
         losses, damages, penalties, fines, forfeitures, reasonable and
         necessary legal fees and related costs, judgments and other costs and
         expenses arising out of or based upon a breach of the obligations of
         the Depositor under this Section 3.22 or the Depositor's negligence,
         bad faith or willful misconduct in connection therewith.

                  (iii) If the indemnification provided for herein is
         unavailable or insufficient to hold harmless the Depositor or the
         Trustee, as applicable, then the other party, in connection with a
         breach of its respective obligations under this Section 3.22 or its
         respective negligence, bad faith or willful misconduct in connection
         therewith, agrees that it shall contribute to the amount paid or
         payable by the other party as a result of the losses, claims, damages
         or liabilities of the other party in such proportion as is appropriate
         to reflect the relative fault and the relative benefit of the Depositor
         on the one hand and the Trustee on the other.

         (d) Nothing shall be construed from the foregoing subsections (a), (b)
and (c) to require the Trustee or any officer, director or Affiliate thereof to
sign any Form 10-K or any certification contained therein. Furthermore, the
inability of the Trustee to file a Form 10-K as a result of the lack of required
information as set forth in Section 3.22(a) or required signatures on such Form
10-K or any certification contained therein shall not be regarded as a breach by
the Trustee of any obligation under this Agreement.

         The Seller agrees to execute and file continuation statements for any
Uniform Commercial Code financing statements which were filed in connection with
the Trust. The Seller shall file any financing statements or amendments and
continuation statements thereto required by any change in the Uniform Commercial

         Section 3.24 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

         With respect to any Mortgage Loan which is delinquent in payment by 91
days or more or is an REO Property, the Seller shall have the right to purchase
such Mortgage Loan or REO Property from the Trust at a price equal to the
Purchase Price.

         If at any time the Seller remits to the Trustee a payment for deposit
in the Distribution Account covering the amount of the Purchase Price for such a
Mortgage Loan, then the Trustee shall execute the assignment of such Mortgage
Loan at the request of the Seller without recourse to the Seller which shall
succeed to all the Trustee's right, title and interest in and to such Mortgage
Loan, and all security and documents relative thereto. Such assignment shall be
an assignment outright and not for security. The Seller will thereupon own such
Mortgage, and all such security and documents, free of any further obligation to
the Trustee or the Certificateholders with respect thereto. The Seller shall be
responsible for any transfer costs incurred with respect to a Mortgage Loan
purchased pursuant to this Section 3.24.

                                    ACCOUNTS

         Section 4.01 COLLECTION OF MORTGAGE LOAN PAYMENTS; CUSTODIAL ACCOUNT.

         (a) The Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the related Mortgage Loans to the extent such procedures shall
be consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing, the Servicer may in
its discretion (i) waive any late payment charge and (ii) extend the due dates
for payments due on a Mortgage Note for a Mortgage Loan for a period not greater
than 180 days; provided, however no such extension shall be materially adverse
to the Certificateholders. In the event of any such arrangement, the Servicer
shall make 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, and shall be entitled to
reimbursement therefor in accordance with Section 5.01. 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. In addition, if (x) a Mortgage Loan is in default or default is
imminent or (y) the Servicer delivers to the Trustee a REMIC Opinion, the
Servicer may, (A) amend the related Mortgage Note to reduce the Mortgage Rate
applicable thereto and (B) amend any Mortgage Note for a Mortgage Loan to extend
to the maturity thereof.

         (b) The Servicer shall establish and maintain a segregated Custodial
Account (which shall at all times be an Eligible Account) with a depository
institution in the name of the Servicer for the benefit of the Trustee on behalf
of the Certificateholders and designated "JPMorgan Chase Bank, N.A., as trustee
for registered holders of Nomura Asset Acceptance Corporation, Mortgage
Pass-Through Certificates, Series 2005-AR1". On behalf of the Trust Fund, the
Servicer shall deposit or cause to be deposited in the clearing account in which
it customarily deposits payments and collection on Mortgage Loans in connection
with its mortgage loan servicing activities on a daily basis and in no event
more than one Business Day after the Servicer's receipt thereof, and shall
thereafter deposit in the Custodial Account, in no event more than two Business
Days after the Servicer's receipt thereof, except as otherwise specifically
provided herein, the following payments and collections remitted by subservicers
or received by it in respect of the Mortgage Loans subsequent to the Cut-off
Date (other than in respect of principal and interest due on the related
Mortgage Loans on or before the Cut-off Date) and the following amounts required
to be deposited hereunder:

                  (i) all payments on account of principal, including Principal
         Prepayments and Subsequent Recoveries, on the Mortgage Loans;

                  (ii) all payments on account of interest on the Mortgage Loans
         net of the related Servicing Fee permitted under Section 3.10;

                                      -73-
<PAGE>

                  (iii) all Liquidation Proceeds, Insurance Proceeds and
         condemnation proceeds with respect to the Mortgage Loans, other than
         proceeds to be applied to the restoration or repair of the related
         Mortgaged Properties or released to the Mortgagor in accordance with
         the Servicer's normal servicing procedures;

                  (iv) any amount required to be deposited by the Servicer
         pursuant to Section 4.01(c) in connection with any losses on Permitted
         Investments;

                  (v) any amounts required to be deposited by the Servicer
         pursuant to Section 3.05;

                  (vi) any amounts paid by an Advance Financing Person in
         respect of Advances or Servicing Advances;

                  (vii) any Prepayment Charges collected by the Servicer in
         connection with the Principal Prepayment of any of the Mortgage Loans
         and any Servicer Prepayment Charge Payment Amounts;

                  (viii) the Purchase Price with respect to any Mortgage Loans
         purchased by the Seller pursuant to Section 2.02 or 2.03, any amounts
         which are to be treated pursuant to Section 2.04 of this Agreement as
         the payment of such a Purchase Price; and

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

         The foregoing requirements for deposit by the Servicer into the
Custodial Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of late
payment charges or assumption fees, if collected, need not be deposited by the
Servicer. In the event that the Servicer shall deposit any amount not required
to be deposited and not otherwise subject to withdrawal pursuant to Section
4.02, it may at any time withdraw or direct the institution maintaining the
Custodial Account, to withdraw such amount from the Custodial Account, any
provision herein to the contrary notwithstanding. Such withdrawal or direction
may be accomplished by delivering written notice thereof to the institution
maintaining the Custodial Account, that describes the amounts deposited in error
in the Custodial Account. The Servicer shall maintain adequate records with
respect to all withdrawals made pursuant to this Section. All funds deposited in
the Custodial Account shall be held in trust for the Certificateholders until
withdrawn in accordance with Section 4.02.

         (c) The institution that maintains the Custodial Account or other
authorized entity shall invest the funds in the Custodial Account, in the manner
directed by the Servicer, in Permitted Investments which shall mature not later
than the next succeeding Remittance Date and shall not be sold or disposed of
prior to its maturity. All such Permitted Investments shall be made in the name
of the Trustee, for the benefit of the Certificateholders. All income and gain
net of any losses realized from any such investment shall be for the benefit of
the Servicer as servicing compensation and shall be remitted to it monthly as
provided herein. The amount of any losses incurred in the Custodial Account in
respect of any such investments shall be deposited by the Servicer into the
Custodial Account immediately as realized, out of its own funds.

                                      -74-
<PAGE>

         (d) The Servicer shall give at least thirty (30) days advance notice to
the Trustee, the Seller, each Rating Agency and the Depositor of any proposed
change of location of the Custodial Account prior to any change thereof.

         Section 4.02 PERMITTED WITHDRAWALS FROM THE CUSTODIAL ACCOUNT.

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

                  (i) to pay itself (to the extent not previously paid to or
         withheld by the Servicer), as servicing compensation in accordance with
         Section 3.10, that portion of any payment of interest that equals the
         Servicing Fee for the period with respect to which such interest
         payment was made, and, as additional servicing compensation, those
         other amounts set forth in Section 3.10;

                  (ii) to reimburse the Servicer or an Advance Financing Person
         for (A) any unreimbursed Advances to the extent of amounts received
         which represent late recoveries of payments of principal and/or
         interest (net of the related Servicing Fees), Liquidation Proceeds and
         Insurance Proceeds on the Mortgage Loans with respect to which such
         Advances were made in accordance with the provisions of Section 5.01;
         and (B) any unreimbursed Advances with respect to the final liquidation
         of a Mortgage Loan that are Nonrecoverable Advances, but only to the
         extent that late recoveries of payments of principal and/or interest,
         Liquidation Proceeds and Insurance Proceeds received with respect to
         such Mortgage Loan are insufficient to reimburse the Servicer or an
         Advance Financing Person for such unreimbursed Advances or (C) subject
         to Section 4.02(b), any unreimbursed Advances to the extent of Amounts
         Held For Future Distribution funds held in the Custodial Account that
         were not included in the Available Distribution Amount for the
         preceding Distribution Date;

                  (iii) to reimburse the Servicer or an Advance Financing Person
         for any Nonrecoverable Advances;

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

                  (v) to pay the Servicer any unpaid Servicing Fees and to
         reimburse it or any Advance Financing Person for any unreimbursed
         Servicing Advances, provided, however, that the Servicer's or such
         Advance Financing Person's right to reimbursement for Servicing
         Advances pursuant to this subclause (v) with respect to any Mortgage
         Loan shall be limited to amounts received on particular Mortgage
         Loan(s) (including, for this purpose, late recoveries of payments of
         principal and/or interest, Liquidation Proceeds, Insurance Proceeds,
         condemnation proceeds and purchase and repurchase proceeds) that
         represent late recoveries of the payments for which such Servicing
         Advances were made;

                  (vi) to pay to the Seller or the Depositor with respect to
         each Mortgage Loan or property acquired in respect thereof that has
         been purchased pursuant to Section 2.02, 2.03 or 3.24, all amounts
         received thereon and not taken into account in determining the related
         Stated Principal Balance of such repurchased Mortgage Loan;

                                      -75-
<PAGE>

                  (vii) to pay any expenses recoverable by the Servicer pursuant
         to Section 7.04;

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

                  (ix) to clear and terminate the Custodial Account upon
         termination of this Agreement pursuant to Section 10.01 hereof.

         In addition, no later than 3:00 p.m. Eastern time on the Remittance
Date, the Servicer shall withdraw from the Custodial Account and remit to the
Trustee (a) all amounts deposited in the Custodial Account as of the close of
business on the last day of the related Due Period (net of charges against or
withdrawals from the Custodial Account pursuant to this Section 4.02), plus (b)
all Advances, if any, which the Servicer is obligated to make pursuant to
Section 5.01, minus (c) any amounts attributable to Principal Prepayments,
Liquidation Proceeds, Insurance Proceeds or condemnation proceeds received after
the applicable Prepayment Period, which amounts shall be remitted on the
following Remittance Date, together with any Compensating Interest required to
be deposited in the Custodial Account in connection with such Principal
Prepayment in accordance with Section 5.02, and minus (d) any amounts
attributable to Scheduled Payments collected but due on a Due Date or Due Dates
subsequent to the first day of the month in which such Remittance Date occurs,
which amounts shall be remitted on the Remittance Date next succeeding the Due
Date related to such Scheduled Payment.

         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 Custodial Account pursuant to subclauses (i), (ii), (iv), (v) and (vi)
above. Prior to making any withdrawal from a Custodial Account pursuant to
subclause (iii), the Servicer shall deliver to the Trustee an Officer's
Certificate of a Authorized Servicer Representative indicating the amount of any
previous Advance or Servicing Advance determined by the Servicer to be a
Nonrecoverable Advance and identifying the related Mortgage Loan(s), and their
respective portions of such Nonrecoverable Advance.

         (b) Notwithstanding the foregoing, any Amounts Held For Future
Distribution withdrawn by the Servicer as permitted in Section 4.02(a)(ii) in
reimbursement of Advances previously made by the Servicer shall be appropriately
reflected in the Servicer's records and replaced by the Servicer by deposit in
the Custodial Account, no later than the close of business on any future
Remittance Date on which the funds on deposit in the Custodial Account shall be
less than the amount required to be remitted to the Trust on such Remittance
Date; provided, however that if the rating of the Servicer (including any
Successor Servicer) is less than "BBB", the Servicer shall be required to
replace such funds by deposit to the Distribution Account, no later than the
close of business on the Remittance Date immediately following the Due Period or
Prepayment Period for which such amounts relate.

         Section 4.03 REPORTS TO TRUSTEE.

         On or before the tenth calendar day of each month, the Servicer shall

         actual basis with respect to paid-through dates), the amount of such
         remittance allocable to principal (including a separate breakdown of

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, promptly upon receipt, and retain therein all collections from the
Mortgagors (or advances by the Servicer) for the payment of taxes, assessments,
hazard insurance premiums or comparable items for the account of the Mortgagors.
Nothing herein shall require the Servicer to compel a Mortgagor to establish an
Escrow Account in violation of applicable law.

         Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Servicer out of related collections for any payments made with respect to
each Mortgage Loan pursuant to Section 3.01 (with respect to taxes and
assessments and insurance premiums) and Section 3.05 (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 such Mortgagors on balances in the Escrow Account,
to remove amounts deposited in error or to clear

                                      -77-

accordance with Section 10.01 thereof. The Escrow Account shall not be a part of
the Trust Fund.

         On each applicable Adjustment Date, the Mortgage Rate with respect to
each Mortgage Loan shall be adjusted, in compliance with the requirements of the
related Mortgage and Mortgage Note, to equal the sum of the Index plus the Gross
Margin (rounded in accordance with the related Mortgage Note) subject to the
applicable Periodic Rate Cap, Maximum Mortgage Interest Rate and Minimum
Mortgage Interest Rate, as set forth in the Mortgage Note. The Servicer shall
execute and deliver the notices required by each Mortgage and Mortgage Note,
applicable laws and regulations regarding interest rate adjustments. The
Servicer shall also provide timely notification to the Trustee of all applicable

methods of implementing such interest rate adjustments. Upon the discovery by
the Servicer or the Trustee that the Servicer has failed to adjust a Mortgage
Rate or a Scheduled Payment pursuant to the terms of the related Mortgage Note
and Mortgage, the Servicer shall immediately deposit in the Custodial Account
from its own funds the amount of any interest loss caused thereby without
reimbursement therefor.

of the foregoing, payments in the nature of late payment charges or assumption,
tax service, statement account or payoff, substitution, satisfaction, release
and other like fees and charges, need not be credited by the Servicer to the
Distribution Account.

         (c) The amount at any time credited to the Distribution Account shall
be held uninvested.

         (d) All amounts received by the Trustee shall be deposited immediately

                  (xii) after the occurrence of an event of default under the
         Advance Facility, to reimburse any Advance Financing Person for any
         Advances or Servicing Advances made by such Advance Financing Person
         pursuant to Section 5.01(b) and not reimbursed to such Advance
         Financing Person pursuant to Section 4.02;

(v), inclusive, and (vii) or with respect to any such

                                      -80-

amounts which would have been covered by such subclauses had the amounts not
been retained by the Trustee without being deposited in the Distribution Account
under Section 4.07.

         (c) On each Distribution Date, the Trustee shall distribute funds on

         Section 4.08 DUTIES OF THE CREDIT RISK MANAGER; TERMINATION.

         (a) The Depositor appoints The Murrayhill Company as Credit Risk
Manager. For and on behalf of the Depositor, the Credit Risk Manager will
provide reports and recommendations concerning the Mortgage Loans that are past
due, as to which there has been commencement of foreclosure, as to which there
has been forbearance in exercise of remedies which are in default, as to which a
Mortgagor is the subject of bankruptcy, receivership, or an arrangement of
creditors, or as to which have become REO Properties. Such reports and
recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the Credit Risk Management Agreement and the Credit Risk
Manager shall look solely to the Servicer for all information and data
(including loss and delinquency information and data) and loan level information
and data relating to the servicing of the Mortgage Loans. If the Credit Risk
Manager is no longer able to perform its duties hereunder, the Credit Risk
Manager may be terminated by the Depositor at the direction of
Certificateholders evidencing not less than 66 2/3% of the Voting Rights. The
Depositor may, at its option, cause the appointment of a successor Credit Risk
Manager. Upon any termination of the Credit Risk Manager or the appointment of a
successor Credit Risk Manager, the Depositor shall give written notice thereof
to the Servicer, the Trustee, each Rating Agency and the Credit Risk Manager.
Notwithstanding the foregoing, the termination of the Credit Risk Manager
pursuant to this Section 4.08(a) shall not become effective until the
appointment of a successor Credit Risk Manager.

         (b) Within six months of the Closing Date, the Seller may, at its
option, terminate the Credit Risk Manager if, in its reasonable judgment, (i)
the value of the servicing rights with respect to the Mortgage Loans is
adversely affected as a result of the presence of the Credit Risk Manager or
(ii) the presence of the Credit Risk Manager impairs the ability of the Seller
to transfer the servicing rights with respect to the Mortgage Loans as permitted
by this Agreement. Upon the termination of the Credit Risk Manager, the Seller
may, at its option, cause the Depositor to appoint a successor Credit Risk
Manager. Notice of such termination shall be provided by the Seller to the
Rating Agencies, the Trustee, the Depositor, the Servicer and the Credit Risk
Manager. Upon the appointment of a successor Credit Risk Manager, the Depositor
shall provide written notice thereof to each Rating Agency, the Trustee, the
Servicer and the Credit Risk Manager.

         If the Credit Risk Manager is terminated pursuant to this Section
4.08(b), the Credit Risk Manager shall only be entitled to a fee equal to
0.0050% with respect to each Mortgage Loan for the one year period following
such termination. After the expiration of such one year period, the Credit Risk
Manager shall not be entitled to the Credit Risk Management Fee or any portion
thereof with respect to any Mortgage Loan. The excess of the Credit Risk
Management Fee with respect to each Mortgage Loan over the amount payable to the
Credit Risk Manager as described in this paragraph shall be paid to the Seller
pursuant to Section 4.07(a)(vii).

         Section 4.09 LIMITATION UPON LIABILITY OF THE CREDIT RISK MANAGER.

         Neither the Credit Risk Manager, nor any of the directors, officers,
employees or agents of the Credit Risk Manager, shall be under any liability to
the Trustee, the Certificateholders or the Depositor for any action taken or for
refraining from the taking of any action in good faith pursuant to this
Agreement, in reliance upon information provided by the Servicer under the
Credit Risk Management Agreement or of errors in judgment; provided, however,
that this provision shall not protect the Credit Risk Manager or any such person
against liability that would otherwise be imposed by reason of willful
malfeasance, bad faith or gross negligence in its performance of its duties
under this Agreement or the Credit Risk Management Agreement. The Credit Risk
Manager and any director, officer, employee or agent of the Credit Risk Manager
may rely in good faith on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising hereunder, and may
rely in good faith upon the accuracy of information furnished by the Servicer
pursuant to the Credit Risk Management Agreement in the performance of its
duties thereunder and hereunder.

                           ADVANCES AND DISTRIBUTIONS

         Section 5.01 ADVANCES; ADVANCE FACILITY.

         (a) The Servicer shall make an Advance with respect to any Mortgage
Loan and deposit such Advance in the Distribution Account no later than 3:00
p.m. Eastern time on the Remittance Date in immediately available funds. The
Servicer shall be obligated to make any such Advance only to the extent that
such advance would not be a Nonrecoverable Advance. If the Servicer shall have
determined that it has made a Nonrecoverable Advance or that a proposed Advance
or a lesser portion of such Advance would constitute a Nonrecoverable Advance,
the Servicer shall deliver (i) to the Trustee for the benefit of the
Certificateholders funds constituting the remaining portion of such Advance, if
applicable, and (ii) to the Depositor, each Rating Agency and the Trustee an
Officer's Certificate setting forth the basis for such determination.

         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 Custodial Account that any Amounts 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 Custodial Account to the
Distribution Account. Any funds so applied and transferred shall be replaced by
the Servicer by deposit in the Distribution Account, no later than the close of
business on any future Remittance Date on which the funds on deposit in the
Custodial Account shall be less than the amount required to be remitted to the
Trust on such Remittance Date; provided, however that if the rating of the
Servicer (including any Successor Servicer) is less than "BBB", the Servicer
shall be required to replace such funds by deposit to the Distribution Account,
no later than the close of business on the Remittance Date immediately following
the Due Period or Prepayment Period for which such amounts relate.

         The Servicer shall be entitled to be reimbursed from the Custodial
Account for all Advances of its own funds made pursuant to this Section as
provided in Section 4.02. The obligation to make Advances with respect to any
Mortgage Loan shall continue until such Mortgage Loan is paid in full or the
related Mortgaged Property or related REO Property has been liquidated or until
the purchase or repurchase thereof (or substitution therefor) from the Trust
Fund pursuant to any applicable provision of this Agreement, except as otherwise
provided in this Section 5.01.

         Subject to and in accordance with the provisions of Article VIII
hereof, in the event that the Servicer fails to make such Advance, then the
Trustee, as a Successor Servicer, shall be obligated to make such Advance only
to the extent such Advance, if made, would not constitute a Nonrecoverable
Advance, subject to the provisions of Sections 5.01 and 8.02.

         (b) (i) 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 5.01(b)(v) below, under which (1) the Servicer
assigns or pledges its rights under this Agreement to be reimbursed for any or
all Advances and/or Servicing Advances to (i) a Person,

                                      -83-
<PAGE>

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

                  (ii) If the Servicer enters into an Advance Facility, the
Servicer and the related Advance Financing Person shall deliver to the Trustee
at the address set forth in Section 11.05 hereof no later than the Servicer
Remittance Date immediately following the effective date of such Advance
Facility a written notice (an "Advance Facility Notice"), stating (a) the
identity of the Advance Financing Person and (b) the identity of the Person (the
"Servicer's Assignee") that will, subject to Section 5.01(b)(iii) hereof, have
the right to make withdrawals from the Custodial Account pursuant to Section
4.02 hereof to reimburse previously unreimbursed Advances and/or Servicing
Advances ("Advance Reimbursement Amounts"). Advance Reimbursement Amounts (i)
shall consist solely of amounts in respect of Advances and/or Servicing Advances
for which the Servicer would be permitted to reimburse itself in accordance with
Section 4.02 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 4.02 hereof to the extent
permitted under Section 5.01(b)(v) below.

                  (iii) Notwithstanding the existence of an Advance Facility,
the Servicer, on behalf of the Advance Financing Person and the Servicer's
Assignee, shall be entitled to receive reimbursements of Advances and/or
Servicing Advances in accordance with Section 4.02 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 11.05 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 Custodial Account all
Advance Reimbursement Amounts. Notwithstanding the foregoing, and for the
avoidance of doubt, (i) the Servicer and/or the Servicer's Assignee shall only
be entitled to reimbursement of Advance Reimbursement Amounts hereunder from
withdrawals from the Custodial Account pursuant to Section 4.02 of this
Agreement and shall not otherwise be entitled to make withdrawals or receive
amounts that shall be deposited in the Distribution Account pursuant to Section
4.06 hereof, and (ii) none of the Trustee or the

                                      -84-
<PAGE>

Certificateholders shall have any right to, or otherwise be entitled to, receive
any Advance Reimbursement Amounts to which the Servicer or Servicer's Assignee,
as applicable, shall be entitled pursuant to Section 4.02 hereof. An Advance
Facility may be terminated by the joint written direction of the Servicer and
the related Advance Financing Person. Written notice of such termination shall
be delivered to the Trustee in the manner set forth in Section 11.05 hereof.
None of the Depositor or the Trustee shall, as a result of the existence of any
Advance Facility, have any additional duty or liability with respect to the
calculation or payment of any Advance Reimbursement Amount, nor, as a result of
the existence of any Advance Facility, shall the Depositor or the Trustee have
any additional responsibility to track or monitor the administration of the
Advance Facility or the payment of Advance Reimbursement Amounts to Servicer's
Assignee. The Servicer shall indemnify the Depositor, the Trustee, any successor
Servicer and the Trust Fund for any claim, loss, liability or damage resulting
from any claim by the related Advancing Financing Person, except to the extent
that such claim, loss, liability or damage resulted from or arose out of
negligence, recklessness or willful misconduct on the part of the Depositor, the
Trustee or any successor Servicer, as the case may be, or failure by the
successor Servicer or the Trustee, as the case may be, to remit funds as
required by this Agreement or the commission of an act or omission to act by the
successor Servicer or the Trustee, as the case may be, and the passage of any
applicable cure or grace period, such that an Event of Default under this
Agreement occurs or such entity is subject to termination for cause under this
Agreement. The Servicer shall maintain and provide to any successor Servicer
and, upon request, the Trustee a detailed accounting on a loan-by-loan basis as
to amounts advanced by, pledged or assigned to, and reimbursed to any Advancing
Financing Person. The successor Servicer shall be entitled to rely on any such
information provided by the Servicer, and the successor Servicer shall not be
liable for any errors in such information.

                  (iv) An Advance Financing Person who receives an assignment or
pledge of rights to receive Advance Reimbursement Amounts and/or whose
obligations are limited to the funding of Advances and/or Servicing Advances
pursuant to an Advance Facility shall not be required to meet the criteria for
qualification as the Servicer.

                  (v) As between the 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 the Servicer or
its related Advance Financing Person in error, then the 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.

                  (vi) For purposes of any Officer's Certificate of the Servicer
delivered pursuant to Section 5.01(a), any Nonrecoverable Advance referred to
therein may have been

                                      -85-
<PAGE>

made by the Servicer. In making its determination that any Advance or Servicing
Advance theretofore made has become a Nonrecoverable Advance, the Servicer shall
apply the same criteria in making such determination regardless of whether such
Advance or Servicing Advance shall have been made by the Servicer.

                  (vii) Any amendment to this Section 5.01(b) or to any other
provision of this Agreement that may be necessary or appropriate to effect the
terms of an Advance Facility as described generally in this Section 5.01(b),
including amendments to add provisions relating to a successor Servicer, may be
entered into by the Trustee, the Depositor and the Servicer without the consent
of any Certificateholder, provided such amendment complies with Section 11.01
hereof. All reasonable costs and expenses (including attorneys' fees) of each
party hereto of any such amendment shall be borne solely by the Servicer. The
parties hereto hereby acknowledge and agree that: (a) the Advances and/or
Servicing Advances financed by and/or pledged to an Advance Financing Person
under any Advance Facility are obligations owed to the Servicer payable only
from the cash flows and proceeds received under this Agreement for reimbursement
of Advances and/or Servicing Advances only to the extent provided herein, and
the Trustee and the Trust are not, as a result of the existence of any Advance
Facility, obligated or liable to repay any Advances and/or Servicing Advances
financed by the Advance Financing Person; (b) the Servicer will be responsible
for remitting to the Advance Financing Person the applicable amounts collected
by it as reimbursement for Advances and/or Servicing Advances funded by the
Advance Financing Person, subject to the provisions of this Agreement; and (c)
the Trustee shall not have any responsibility to track or monitor the
administration of the financing arrangement between the Servicer and any Advance
Financing Person.

         Section 5.02 COMPENSATING INTEREST PAYMENTS.

         In the event that there is a Prepayment Interest Shortfall arising from
a voluntary Principal Prepayment in part or in full by the Mortgagor with
respect to any Mortgage Loan, the Servicer shall, to the extent of the Servicing
Fee for such Distribution Date, deposit into the Distribution Account, as a
reduction of and to the extent of, the Servicing Fee for such Distribution Date,
no later than the close of business on the Remittance Date immediately preceding
such Distribution Date, an amount equal to the Prepayment Interest Shortfall;
and in case of such deposit, the Servicer shall not be entitled to any recovery
or reimbursement from the Depositor, the Trustee, the Seller, the Trust Fund or
the related Certificateholders.

         Section 5.03 REMIC DISTRIBUTIONS.

         On each Distribution Date the Trustee, shall be deemed to allocate
distributions to the REMIC I Regular Interests in accordance with Section 5.11
hereof.

         (c) The principal portion of all Realized Losses on the Mortgage Loans
shall be allocated on each Distribution Date as follows: first, to Net Monthly
Excess Cashflow; second, to the Class X Certificates, until the Certificate

Class II-A-3 Certificates and all Classes of Subordinate Certificates on any
Distribution Date shall be so allocated after the actual distributions to be
made on such date as provided above. All references above to the Certificate
Principal Balance of any Class I-A-2 Certificates, Class II-A-3 Certificate or
any Class of Subordinate Certificates shall be to the Certificate Principal
Balance of such Class immediately prior to the relevant Distribution Date,
before reduction thereof by any Realized Losses, in each case to be allocated to
such Class of Certificates, on such Distribution Date.

<PAGE>

         Any allocation of the principal portion of Realized Losses to a Class
I-A-2 Certificate, Class II-A-3 Certificate or Subordinate Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof by the amount so allocated; any allocation of Realized Losses to a Class
X Certificate shall be made by reducing the amount otherwise payable in respect
thereof pursuant to Section 5.06(iii)(14). No allocations of any Realized Losses
shall be made to the Certificate Principal Balances of the Class I-A-1, Class
II-A-1, Class II-A-2 or Class P Certificates.

         All such Realized Losses and all other losses allocated to a Class of
Certificates hereunder will be allocated among the Certificates of such Class in
proportion to the Percentage Interests evidenced thereby.

         (d) Notwithstanding anything to the contrary contained herein, if on
any Distribution Date the Trustee discovers, based solely on the reports
delivered by the Servicer under this Agreement that any Subsequent Recoveries
have been collected by the Servicer with respect to the Mortgage Loans, the
amount of such Subsequent Recoveries will be applied to increase the Certificate
Principal Balance of (i) the Class I-A-3 Certificates with respect to Subsequent
Recoveries relating to the Group I Mortgage Loans, (ii) the Class II-A-3
Certificates with respect to Subsequent Recoveries relating to the Group II
Mortgage Loans and (iii) the Class of Subordinate Certificates with the highest
payment priority to which Realized Losses on the Mortgage Loans have been
allocated, but not by more than the amount of Realized Losses previously
allocated to the Class I-A-2 Certificates, Class II-A-3 Certificates or that
Class of Subordinate Certificates pursuant to this Section 5.07. After the
Certificate Principal Balances of the Class I-A-2 Certificates and Class II-A-2
Certificates have been increased up to the amount of Realized Losses allocated
thereto pursuant to this Section 5.07 to the extent that such Applied Loss
Amounts have not been paid to such certificates as a Deferred Amount, any
additional Subsequent Recoveries with respect to the Mortgage Loans will be
applied to increase the Certificate Principal Balance of the Subordinate
Certificates, beginning with the Class of Subordinate Certificates with the next
highest payment priority, up to the amount of such Realized Losses previously
allocated to such Class of Certificates pursuant to this Section 5.07 but only
to the extent that any such Applied Loss Amount has not been paid to any Class
of Certificates as a Deferred Amount. Holders of such Certificates will not be
entitled to any payment in respect of current interest on the amount of such
increases for any Accrual Period preceding the Distribution Date on which such
increase occurs. Any such increases shall be applied to the Certificate
Principal Balance of each Class I-A-2 Certificate, Class II-A-3 Certificate or
each Subordinate Certificate of such Class in accordance with its respective
Percentage Interest.

         (e) The REMIC I Marker Allocation Percentage of all Realized Losses on
the Mortgage Loans shall be allocated on each Distribution Date to the following
REMIC I Regular Interests in the specified percentages, as follows: first, to
Uncertificated Accrued Interest payable to the REMIC I Regular Interest LTI-AA
and REMIC I Regular Interest LTI-ZZ up to an aggregate amount equal to the REMIC
I Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the
Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I
Regular Interest LTI-M5 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC I Regular
Interest LTI-M5 has been reduced to zero; third, to the Uncertificated Principal
Balances of the REMIC I

                                      -94-
<PAGE>

Regular Interest LTI-AA and REMIC I Regular Interest LTI-ZZ up to an aggregate
amount equal to the REMIC I Principal Loss Allocation Amount, 98% and 2%,
respectively; fourth, to the Uncertificated Principal Balances of REMIC I
Regular Interest LTI-AA, REMIC I Regular Interest LTI-M4 and REMIC I Regular
Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Principal Balance of REMIC I Regular Interest LTI-M4 has been reduced to zero;
fifth, to the Uncertificated Principal Balances of REMIC I Regular Interest
LTI-AA, REMIC I Regular Interest LTI-M3 and REMIC I Regular Interest LTI-ZZ,
98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of
REMIC I Regular Interest LTI-M3 has been reduced to zero; sixth, to the
Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I
Regular Interest LTI-M2 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC I Regular
Interest LTI-M2 has been reduced to zero; seventh, to the Uncertificated
Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest
LTI-M1 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until
the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M1 has been
reduced to zero; eighth, with respect to Realized Losses on the Group I Mortgage
Loans only, to the Uncertificated Principal Balances of REMIC I Regular Interest
LTI-AA, REMIC I Regular Interest LTI-IA2 and REMIC I Regular Interest LTI-ZZ,
98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of
REMIC I Regular Interest LTI-IA2 has been reduced to zero; and ninth, with
respect to Realized Losses on the Group II Mortgage Loans only, to the
Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I
Regular Interest LTI-IIA3 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%,
respectively, until the Certificate Principal Balance of REMIC I Regular
Interest LTI-IIA3 has been reduced to zero.

         The REMIC I Sub WAC Allocation Percentage of all Realized Losses on the
Mortgage Loans shall be applied after all distributions have been made on each
Distribution Date first, so as to keep the Uncertificated Principal Balance of
each REMIC I Regular Interest ending with the designation "GRP" equal to 0.01%
of the aggregate Stated Principal Balance of the Mortgage Loans in the related
Loan Group; second, to each REMIC I Regular Interest ending with the designation
"SUB," so that the Uncertificated Balance of each such REMIC I Regular Interest
is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of
the Mortgage Loans in the related Loan Group over (y) the current Certificate
Principal Balance of the Senior Certificate in the related Loan Group (except
that if any such excess is a larger number than in the preceding distribution
period, the least amount of Realized Losses shall be applied to such REMIC I
Regular Interests such that the REMIC I Subordinated Balance Ratio is
maintained); and third, any remaining Realized Losses shall be allocated to
REMIC I Regular Interest LTI-XX.

         Section 5.08 PREPAYMENT CHARGES.

         On each Distribution Date, all amounts representing Prepayment Charges
in respect of the Mortgage Loans received during the related Prepayment Period
and deposited in the Distribution Account will be withdrawn from the
Distribution Account and distributed by the Trustee in accordance with the
Remittance Report to the Class P Certificates and shall not be available for
distribution to the holders of any other Class of Certificates. The payment of
such Prepayment Charges shall not reduce the Certificate Principal Balance of
the Class P Certificates.

         Section 5.12 CLASS P CERTIFICATE ACCOUNT.

         Section 5.13 BASIS RISK SHORTFALL RESERVE FUND.

         (a) The Trustee shall establish a Basis Risk Shortfall Reserve Fund on
behalf of the holders of the Publicly Offered Certificates (other than the Group
I Certificates). The Basic Risk Shortfall Reserve Fund must be an Eligible
Account. The Basis Risk Shortfall Reserve Fund shall be entitled "Basis Risk
Shortfall Reserve Fund, JPMorgan Chase Bank, N.A., as Trustee for the benefit of
holders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through
Certificates, Series 2005-AR1, Class II-A-1, Class II-A-2, Class II-A-3, Class
M-1, Class M-2, Class M-3, Class M-4 and Class M-5". Any payments received by
the Trustee under the Cap Contract shall be deposited into the Basis Risk
Shortfall Reserve Fund for the benefit of the Class II-A-2 Certificates;
provided that the amount of any Excess Cap Payments shall be held for the
benefit of the Class X Certificates and payable as part of the Class X
Distribution Amount for the related Distribution Date. On each Distribution Date
as to which there is a Basis Risk Shortfall payable to any Class of
Certificates, the Trustee shall deposit the amounts pursuant to

                                     -100-
<PAGE>

paragraphs 8, 9, 10, 11, 12 and 13 of Section 5.06(iii) into the Basis Risk
Shortfall Reserve Fund and the Trustee has been directed by the Class X
Certificateholder to distribute such amounts to the Holders of the Publicly
Offered Certificates (other than the Group I Certificates) in the amounts and
priorities set forth in Section 5.06(iii).

         (b) The Basis Risk Shortfall Reserve Fund is an "outside reserve fund"
within the meaning of Treasury Regulation ss.1.860G-2(h) and shall be an asset
of the Trust Fund but not an asset of any REMIC. The Trustee on behalf of the
Trust shall be the nominal owner of the Basis Risk Shortfall Reserve Fund. The
Class X Certificateholders shall be the beneficial owners of the Basis Risk
Shortfall Reserve Fund, subject to the power of the Trustee to transfer amounts
under Section 5.06(iii). Amounts in the Basis Risk Shortfall Reserve Fund shall
be held either uninvested in a trust or deposit account of the Trustee with no
liability for interest or other compensation thereof or, at the written
direction of the Majority Class X Certificateholder, be invested in Permitted
Investments that mature no later than the Business Day prior to the next
succeeding Distribution Date. All net income and gain from such investments
shall be distributed to the Majority Class X Certificateholder, not as a
distribution in respect of any interest in any REMIC, on such Distribution Date.
All amounts earned on amounts on deposit in the Basis Risk Shortfall Reserve
Fund shall be taxable to the Majority Class X Certificateholder. Any losses on
such investments shall be deposited in the Basis Risk Shortfall Reserve Fund by
the Majority Class X Certificateholder out of its own funds immediately as
realized. In the event that the Majority Class X Certificateholder shall fail to
provide investment instructions to the Trustee, the amounts on deposit in the
Basis Risk Shortfall Reserve Fund shall be held uninvested.

         (c) For federal tax return and information reporting, the value of the
right of the holders of the Class II-A-2 Certificates to receive payments from
the Basis Risk Shortfall Reserve Fund in respect of any Basis Risk Shortfall
shall be $35,000. The value of such right with respect to the Publicly Offered
Certificates (other than the Group I Certificates and Class II-A-2 Certificates)
shall be zero.

         The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer upon the written order of the
Depositor. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized
to sign on behalf of the Trustee shall bind the Trustee, 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 the countersignature of the Trustee by manual
signature, and such countersignature upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
countersigned and delivered hereunder. All Certificates shall be dated the date
of their countersignature. On the Closing Date, the Trustee shall authenticate
the Certificates to be issued at the written direction of the Depositor, or any
affiliate thereof.

a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

         Section 6.02 CERTIFICATE REGISTER; REGISTRATION OF TRANSFER AND
                      EXCHANGE OF CERTIFICATES.

         (a) The Trustee shall maintain, or cause to be maintained in accordance
with the provisions of Section 6.09, a Certificate Register for the Trust Fund
in which, subject to the provisions of subsections (b) and (c) below and to such
reasonable regulations as it may prescribe, the Trustee shall provide for the
registration of Certificates and of Transfers and exchanges of Certificates as
herein provided. Upon surrender for registration of Transfer of any Certificate,
the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates of the same Class and of
like aggregate Percentage Interest.

         At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Trustee. Whenever any Certificates are
so surrendered for exchange, the Trustee 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 Trustee duly executed by the holder thereof or his
attorney duly authorized in writing.

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

         All Certificates surrendered for registration of Transfer or exchange
shall be canceled and subsequently destroyed by the Trustee in accordance with
the Trustee's customary procedures.

         (b) No Transfer of a Private 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 each certify
to the Trustee in writing the facts surrounding the Transfer in substantially
the forms set forth in Exhibit E (the "Transferor Certificate") and (x) deliver
a letter in substantially the form of either Exhibit F (the "Investment Letter")
or Exhibit G (the "Rule 144A Letter") or (y) there shall be delivered to the
Trustee an Opinion of Counsel, at the expense of the transferor, 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 Seller, the
Trustee or the Trust Fund. The Depositor shall provide to any Holder of a
Private 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

                                     -103-
<PAGE>

the condition to eligibility set forth in Rule 144A(d)(4) for Transfer of any
such Certificate without registration thereof under the Securities Act pursuant
to the registration exemption provided by Rule 144A. The Trustee shall cooperate
with the Depositor in providing the Rule 144A information referenced in the
preceding sentence, including providing to the Depositor such information
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 Private Certificate desiring to
effect such Transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor and the Seller against any liability that may result if the Transfer
is not so exempt or is not made in accordance with such federal and state laws.

         No Transfer of an ERISA Restricted Certificate shall be made unless the
Trustee shall have received either (i) a representation from the transferee of
such Certificate acceptable to and in form and substance satisfactory to the
Trustee to the effect that such transferee is not an employee benefit plan
subject to Section 406 of ERISA and/or a plan subject to Section 4975 of the
Code, or a Person acting on behalf of any such plan or using the assets of any
such plan, or (ii) in the case of any such ERISA Restricted Certificate
presented for registration in the name of an employee benefit plan subject to
ERISA, or a plan subject to Section 4975 of the Code (or comparable provisions
of any subsequent enactments), or a trustee of any such plan or any other person
acting on behalf of any such plan, an Opinion of Counsel satisfactory to the
Trustee for the benefit of the Trustee, the Depositor and the Servicer and on
which they may rely to the effect that the purchase and holding of such ERISA
Restricted Certificate is permissible under applicable law, will not result in
any prohibited transactions under ERISA or Section 4975 of the Code and will not
subject the Trustee, the Depositor or any Servicer to any obligation in addition
to those expressly undertaken in this Agreement, which Opinion of Counsel shall
not be an expense of the Trustee, the Depositor or any Servicer. Notwithstanding
anything else to the contrary herein, any purported transfer of an ERISA
Restricted Certificate to or on behalf of an employee benefit plan subject to
Section 406 of ERISA and/or a plan subject to Section 4975 of the Code other
than in compliance with the foregoing shall be void and of no effect; provided
that the restriction set forth in this sentence shall not be applicable if there
has been delivered to the Trustee an Opinion of Counsel meeting the requirements
of clause (ii) of the first sentence of this paragraph. The Trustee shall not be
under any liability to any Person for any registration of transfer of any ERISA
Restricted Certificate that is in fact not permitted by this Section 6.02(b) or
for making any payments due on such Certificate to the Holder thereof or taking
any other action with respect to such Holder under the provisions of this
Agreement. The Trustee shall be entitled, but not obligated, to recover from any
Holder of any ERISA Restricted Certificate that was in fact an employee benefit
plan subject to Section 406 of ERISA or a plan subject to Section 4975 of the
Code or a Person acting on behalf of any such plan at the time it became a
Holder or, at such subsequent time as it became such a plan or Person acting on
behalf of such a plan, all payments made on such ERISA Restricted Certificate at
and after either such time. Any such payments so recovered by the Trustee shall
be paid and delivered by the Trustee to the last preceding Holder of such
Certificate that is not such a plan or Person acting on behalf of a plan.

         Each beneficial owner of a Class M-1, Class M-2, Class M-3, Class M-4
or Class M-5 Certificate or any interest therein shall be deemed to have
represented, by virtue of its acquisition or holding of that certificate or
interest therein, that either (i) it is not a Plan or investing with "Plan
Assets", (ii) it has acquired and is holding such certificate in reliance on the
Exemption,

                                     -104-
<PAGE>

and that it understands that there are certain conditions to the availability of
the Exemption, including that the certificate must be rated, at the time of
purchase, not lower than "BBB-" (or its equivalent) by S&P or Moody's, and the
certificate is so rated or (iii) (1) it is an insurance company, (2) the source
of funds used to acquire or hold the certificate or interest therein is an
"insurance company general account," as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60 and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

         (c) Each Person who has or who acquires any Ownership Interest in a
Residual 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 Residual
Certificate are expressly subject to the following provisions:

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

                  (ii) No Ownership Interest in a Residual Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Residual Certificate
         unless, in addition to the certificates required to be delivered to the
         Trustee under subparagraph (b) above, the Trustee shall have been
         furnished with an affidavit (a "Transfer Affidavit") of the initial
         owner or the proposed transferee in the form attached hereto as Exhibit
         D.

                  (iii) Each Person holding or acquiring any Ownership Interest
         in a Residual 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 Residual 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 Residual Certificate and (C) not to Transfer its Ownership Interest
         in a Residual Certificate or to cause the Transfer of an Ownership
         Interest in a Residual Certificate to any other Person if it has actual
         knowledge that such Person is not a Permitted Transferee.

                  (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Residual Certificate in violation of the provisions of
         this Section 6.02(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 Residual Certificate in violation of the
         provisions of this Section 6.02(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 Residual
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Residual Certificate that is in fact
         not permitted by Section 6.02(b) and this Section 6.02(c) or for making
         any payments due on such Certificate to the Holder thereof or taking
         any other action with respect to such Holder under the provisions of
         this Agreement so long as the Transfer was registered after receipt of
         the related Transfer Affidavit. The Trustee shall be entitled but not
         obligated to recover from any Holder of a Residual 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

                                     -105-
<PAGE>

         Transferee, all payments made on such Residual Certificate at and after
         either such time. Any such payments so recovered by the Trustee shall
         be paid and delivered by the Trustee to the last preceding Permitted
         Transferee of such Certificate.

         The restrictions on Transfers of a Residual Certificate set forth in
this Section 6.02(c) shall cease to apply (and the applicable portions of the
legend on a Residual Certificate may be deleted) with respect to Transfers
occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion
of Counsel shall not be an expense of the Trustee or the Seller to the effect
that the elimination of such restrictions will not cause any REMIC 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, a Certificateholder or another
Person. Each Person holding or acquiring any ownership Interest in a Residual
Certificate hereby consents to any amendment of this Agreement that, based on an
Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Residual
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 Residual Certificate that is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

         (d) The preparation and delivery of all certificates and opinions
referred to above in this Section 6.02 shall not be an expense of the Trust
Fund, the Trustee, the Depositor or the Seller.

         Section 6.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

         If (a) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is delivered to
the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Trustee that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute, authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
Class, tenor and Percentage Interest. In connection with the issuance of any new
Certificate under this Section 6.03, the Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Trustee) connected therewith. Any replacement Certificate issued pursuant to
this Section 6.03 shall constitute complete and indefeasible evidence of
ownership in the Trust Fund, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time. All Certificates
surrendered to the Trustee under the terms of this Section 6.03 shall be
canceled and destroyed by the Trustee in accordance with its standard procedures
without liability on its part.

         Section 6.04 PERSONS DEEMED OWNERS.

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

         Section 6.05 ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND ADDRESSES.

         If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the
Depositor shall request such information in writing from the Trustee, then the
Trustee shall, within ten Business Days after the receipt of such request,
provide the Depositor or such Certificateholders at such recipients' expense the
most recent list of the Certificateholders of the Trust Fund held by the
Trustee, if any. The Depositor and every Certificateholder, by receiving and
holding a Certificate, agree that the Trustee shall not be held accountable by
reason of the disclosure of any such information as to the list of the
Certificateholders hereunder, regardless of the source from which such
information was derived.

         Section 6.06 BOOK-ENTRY CERTIFICATES.

         The Certificates, other than the Class X, Class P and Class R
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. Such Certificates
shall initially be registered on the Certificate Register in the name of the
Depository or its nominee, and no Certificate Owner of such Certificates will
receive a definitive certificate representing such Certificate Owner's interest
in such Certificates, except as provided in Section 6.08. Unless and until
definitive, fully registered Certificates ("Definitive Certificates") have been
issued to the Certificate Owners of such Certificates pursuant to Section 6.08:

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

         (b) the Depositor and the Trustee may deal with the Depository and the
Depository Participants for all purposes (including the making of distributions)
as the authorized representative of the respective Certificate Owners of such
Certificates;

         (c) registration of the Book-Entry Certificates may not be transferred
by the Trustee except to another Depository;

         (d) the rights of the respective Certificate Owners of such
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 such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued pursuant to Section 6.08, the Depository will make
book-entry transfers among the Depository Participants and receive and transmit
distributions of principal and interest on the related Certificates to such
Depository Participants;

         (e) the Depository may collect its usual and customary fees, charges
and expenses from its Depository Participants;

         (f) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants; and (g) to the extent that the provisions of this Section conflict
with any other provisions of this Agreement, the provisions of this Section
shall control.

                                     -107-

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

         Section 6.07 NOTICES TO DEPOSITORY.

         Whenever any notice or other communication is required to be given to
Certificateholders of a 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 Trustee shall give all such notices and
communications to the Depository.

         Section 6.08 DEFINITIVE CERTIFICATES.

         If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depositor or the Depository advises the Trustee that the
Depository is no longer willing or able to discharge properly its
responsibilities under the Depository Agreement with respect to such
Certificates and the Trustee or the Depositor is unable to locate a qualified
successor, (b) the Depositor, at its sole option, advises the Trustee that it
elects to terminate the book-entry system with respect to such Certificates
through the Depository or (c) after the occurrence and continuation of an Event
of Default, Certificate Owners of such Book-Entry Certificates having not less
than 51% of the Voting Rights evidenced by any Class of Book-Entry Certificates
advise the Trustee and the Depository in writing through the Depository
Participants that the continuation of a book-entry system with respect to
Certificates of such Class through the Depository (or its successor) is no
longer in the best interests of the Certificate Owners of such Class, then the
Trustee shall notify all Certificate Owners of such Certificates, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Certificates to applicable Certificate Owners requesting the same.
The Depositor shall provide the Trustee with an adequate inventory of
certificates to facilitate the issuance and transfer of Definitive Certificates.
Upon surrender to the Trustee of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall countersign and deliver such Definitive Certificates. Neither
the Depositor nor the Trustee shall be liable for any delay in delivery of such
instructions and each may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of such Definitive
Certificates, all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed by
the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

         Section 6.09 MAINTENANCE OF OFFICE OR AGENCY.

         The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies at 2001 Bryan Street, 8th Floor, Dallas,

                         THE DEPOSITOR AND THE SERVICER

         Section 7.01 LIABILITIES OF THE DEPOSITOR AND THE SERVICER.

         Each of the Depositor and the Servicer shall be liable in accordance

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,
the Certificates or any of the Mortgage Loans and to perform its duties under
this Agreement.

         (b) Any Person into which the Depositor or any Servicer may be merged
or consolidated, or any corporation resulting from any merger or consolidation
to which the Depositor or the Servicer shall be a party, or any Person
succeeding to the business of the Depositor or the Servicer shall be the
successor of the Depositor or the Servicer hereunder, 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.

         Section 7.03 INDEMNIFICATION OF DEPOSITOR AND THE SERVICER.

         (a) The Depositor agrees to indemnify the Indemnified Persons for, and
to hold them harmless against, any loss, liability or expense (including
reasonable legal fees and disbursements of counsel) incurred on their part that
may be sustained in connection with, arising out of, or relating to, any claim
or legal action (including any pending or threatened claim or legal action)
relating to this Agreement or the Certificates (i) related to the Depositor's
failure to perform its duties in compliance with this Agreement (except as any
such loss, liability or expense shall be otherwise reimbursable pursuant to this
Agreement) or (ii) incurred by reason of the Depositor's willful misfeasance,
bad faith or gross negligence in the performance of duties hereunder or by
reason of reckless disregard of obligations and duties hereunder. This indemnity
shall survive the resignation and the termination of this Agreement.

         (b) The Servicer agrees to indemnify the Indemnified Persons for, and
to hold them harmless against, any loss, liability or expense (including
reasonable legal fees and disbursements of counsel) incurred on their part that
may be sustained in connection with, arising out of, or relating to, any claim
or legal action (including any pending or threatened claim or legal action)
relating to the Servicer's gross negligence in the performance of its duties
under this Agreement or failure to service the Mortgage Loans in material
compliance with the terms of this Agreement and for a material breach of any
representation, warranty or covenant of the Servicer contained herein. The
Servicer shall immediately notify the Trustee if a claim is made by a third
party with respect to this Agreement or the Mortgage Loans, assume (with the
consent of the

                                     -110-
<PAGE>

Trustee and with counsel reasonably satisfactory to the Trustee) the defense of
any such claim and pay all expenses in connection therewith, including counsel
fees, and promptly appeal or pay, discharge and satisfy any judgment or decree
which may be entered against it or any Indemnified Person in respect of such
claim but failure to so notify the Servicer shall not limit its obligations
hereunder. The Servicer agrees that it will not enter into any settlement of any
such claim without the consent of the Indemnified Persons unless such settlement
includes an unconditional release of such Indemnified Persons from all liability
that is the subject matter of such claim. The provisions of this Section 7.03(b)
shall survive termination of this Agreement.

         Section 7.04 LIMITATIONS ON LIABILITY OF THE DEPOSITOR, THE SERVICER
AND OTHERS.

         Subject to the obligation of the Depositor and the Servicer to
indemnify the Indemnified Persons pursuant to Section 7.03:

         (a) Neither the Depositor, the Servicer nor any of the directors,
officers, employees or agents of the Depositor and the Servicer shall be under
any liability to the Indemnified Persons, the Trust Fund or the
Certificateholders for taking any action or for refraining from taking any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositor, the
Servicer or any such Person against any breach of warranties or representations
made herein or any liability which would otherwise be imposed by reason of such
Person's willful misfeasance, bad faith or gross negligence in the performance
of duties or by reason of reckless disregard of obligations and duties
hereunder.

         (b) The Depositor, the Servicer and any director, officer, employee or
agent of the Depositor and the Servicer may rely in good faith on any document
of any kind prima facie properly executed and submitted by any Person respecting
any matters arising hereunder.

         (c) The Depositor, the Servicer, the Trustee, the Custodian and any
director, officer, employee or agent of the Depositor, the Servicer, the Trustee
or the Custodian shall be indemnified by the Trust Fund and held harmless
thereby against any loss, liability or either expense (including reasonable
legal fees and disbursements of counsel) incurred on their part that may be
sustained in connection with, arising out of, or related to, any claim or legal
action (including any pending or threatened claim or legal action) relating to
this Agreement or the Certificates, other than (i) with respect to the Servicer,
such loss, liability or expense related to the Servicer's failure to perform its
duties in compliance with this Agreement (except as any such loss, liability or
expense shall be otherwise reimbursable pursuant to this Agreement) or, with
respect to the Custodian, to the Custodian's failure to perform its duties
hereunder, (ii) with respect to the Servicer, any such loss, liability or
expense incurred by reason of the Servicer's willful misfeasance, bad faith or
gross negligence in the performance of its duties hereunder or (iii) with
respect to the Custodian, any such loss, liability or expense incurred by reason
of the Custodian's willful misfeasance, bad faith or gross negligence in the
performance of its duties hereunder.

         (d) Neither the Depositor nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties under this Agreement and that in its opinion may
involve it in any expense or liability; provided, however, the Trustee may in
its discretion, undertake any such action which it may deem necessary or
desirable with

                                     -111-
<PAGE>

respect to this Agreement and the rights and duties of the parties hereto and
the interests of the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Trustee shall be
entitled to be reimbursed therefor out of the Distribution Account as provided
by Section 4.05. Nothing in this Subsection 7.04(d) shall affect the Trustee's
obligation to take such actions as are necessary to ensure the servicing and
administration of the Mortgage Loans pursuant to this Agreement.

         (e) In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, the
Trustee shall not be required to investigate or make recommendations concerning
potential liabilities which the Trust might incur as a result of such course of
action by reason of the condition of the Mortgaged Properties.

         (f) The Trustee shall not be liable for any acts or omissions of the
Servicer, the Depositor or the Custodian.

         Section 7.05 SERVICER NOT TO RESIGN.

         The Servicer shall not resign from the obligations and duties hereby
imposed on it except upon the determination that its duties hereunder are no
longer permissible under applicable law or the performance of such duties are no
longer possible in order to comply with applicable law and such incapacity or
impossibility cannot be cured by the Servicer. Any determination permitting the
resignation of the Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee which Opinion of Counsel shall be in form and
substance acceptable to the Trustee. No appointment of a successor to the
Servicer shall be effective hereunder unless (a) the Rating Agencies have
confirmed in writing that such appointment will not result in a downgrade,
qualification or withdrawal of the then current ratings assigned to the
Certificates, (b) such successor shall have represented that it is meets the
eligibility criteria set forth in Section 8.02 and (c) such successor has agreed
to assume the obligations of the Servicer hereunder to the extent of the
Mortgage Loans. The Servicer shall provide a copy of the written confirmation of
the Rating Agencies and the agreement executed by such successor to the Trustee.
No such resignation shall become effective until a Qualified Successor or the
Trustee shall have assumed the Servicer's responsibilities and obligations
hereunder. The Servicer shall notify the Trustee and the Rating Agencies of its
resignation.

         Section 7.06 TERMINATION OF SERVICER WITHOUT CAUSE; APPOINTMENT OF
SPECIAL SERVICER.

         (a) The Seller may, at its option, terminate the servicing
responsibilities of GMAC Mortgage Corporation as Servicer hereunder with respect
to the Mortgage Loans without cause. No such termination shall become effective
unless and until a successor to GMAC Mortgage Corporation shall have been
appointed to service and administer the related Mortgage Loans pursuant to the
terms and conditions of this Agreement. No appointment shall be effective unless
(i) such successor to GMAC Mortgage Corporation meets the eligibility criteria
contained in Section 8.02, (ii) the Trustee shall have consented to such
appointment, (iii) the Rating Agencies have confirmed in writing that such
appointment will not result in a downgrade, qualification or withdrawal of the
then current ratings assigned to the Certificates, (iv) such successor has
agreed to assume the obligations of GMAC Mortgage Corporation hereunder to

                                     -112-
<PAGE>

the extent of the Mortgage Loans and (v) all amounts reimbursable to GMAC
Mortgage Corporation pursuant to the terms of this Agreement shall have been
paid to GMAC Mortgage Corporation by the successor appointed pursuant to the
terms of this Section 7.06 or by the Seller including without limitation, all
unreimbursed Advances and Servicing Advances made by GMAC Mortgage Corporation
and all out-of-pocket expenses of GMAC Mortgage Corporation incurred in
connection with the transfer of servicing to such successor. The Seller shall
provide a copy of the written confirmation of the Rating Agencies and the
agreement executed by such successor to the Trustee.

         (b) In addition, the Seller may, at its option, appoint a special
servicer with respect to certain of the Mortgage Loans. The Seller and GMAC
Mortgage Corporation shall negotiate in good faith with any proposed special
servicer with respect to the duties and obligations of such special servicer
with respect to any such Mortgage Loan. Any subservicing agreement shall contain
terms and provisions acceptable to the Trustee and shall obligate the special
servicer to service such Mortgage Loans in accordance with Accepted Servicing
Practices. The fee payable to the special servicer for the performance of such
duties and obligations will paid from the Servicing Fee collected by GMAC
Mortgage Corporation with respect to each such Mortgage Loan and will be
remitted to such special servicer by GMAC Mortgage Corporation.

                        DEFAULT; TERMINATION OF SERVICER

         Section 8.01 SERVICER DEFAULT.

         In case one or more of the following events of default by the Servicer
(each, a "Servicer Default") shall occur and be continuing, that is to say:

                  (i) any failure to remit to the Trustee any payment required
to be made under the terms of this Agreement which continues unremedied for a
period of three Business Days; or

                  (ii) failure duly to observe or perform in any material
respect any other of the covenants or agreements set forth in this Agreement,
the breach of which has a material adverse effect and which continue unremedied
for a period of sixty days after the date on which written notice of such
failure, requiring the same to be remedied, shall have been given to the
Servicer by the Trustee; or

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

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

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

                  (vi) the Servicer attempts to assign its right to servicing
compensation hereunder (other than any payment by the Servicer of any portion of
the Servicing Fee to the Seller as provided in a separate side letter between
the Seller and the Servicer) or the Servicer attempts to sell or otherwise
dispose of all or substantially all of its property or assets or to assign this
Agreement or the servicing responsibilities hereunder or to delegate its duties
hereunder or any portion thereof except, in each case as otherwise permitted
herein; or

                  (vii) the Servicer ceases to be qualified to transact business
in any jurisdiction where it is currently so qualified, but only to the extent
such non-qualification materially and adversely affects the Servicer's ability
to perform its obligations hereunder; or

         then, and in each and every such case, so long as a Servicer Default
shall not have been remedied, the Trustee, by notice in writing to the Servicer
shall with respect to a payment default

                                     -114-
<PAGE>

by the Servicer pursuant to Section 8.01(i) and, upon the occurrence and
continuance of any other Servicer Default, may, and, at the written direction of
Certificateholders evidencing not less than 25% of the Voting Rights shall, in
addition to whatever rights the Trustee on behalf of the Certificateholders may
have under Section 7.03 and at law or equity to damages, including injunctive
relief and specific performance, terminate all the rights and obligations of the
Servicer under this Agreement and in and to the Mortgage Loans and the proceeds
thereof without compensating the Servicer for the same. On or after the receipt
by the Servicer of such written notice, all authority and power of the Servicer
under this Agreement whether with respect to the Mortgage Loans or otherwise,
shall pass to and be vested in the Trustee. Upon written request from the
Trustee, the Servicer shall prepare, execute and deliver, any and all documents
and other instruments, place in the Trustee's possession all Mortgage Files
relating to the related Mortgage Loans, and 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, at the Servicer's sole
expense. The defaulting Servicer shall cooperate with the Trustee in effecting
the termination of its responsibilities and rights hereunder including, without
limitation, the transfer to such successor for administration by it of all cash
amounts which shall at the time be credited by the defaulting Servicer to the
Custodial Account or Escrow Accounts or thereafter received with respect to the
Mortgage Loans or any related REO Property (provided, however, that the
defaulting Servicer shall continue to be entitled to receive all amounts accrued
or owing to it under this Agreement on or prior to the date of such termination,
whether in respect of Advances, Servicing Advances, accrued and unpaid Servicing
Fees or otherwise, and shall continue to be entitled to the benefits of Section
7.04, notwithstanding any such termination, with respect to events occurring
prior to such termination). The Trustee shall not have knowledge of a Servicer
Default unless a Responsible Officer of the Trustee has actual knowledge or
unless written notice of any Servicer Default is received by the Trustee at its
Corporate Trust Office and such notice references the Certificates, the Trust
Fund or this Agreement.

         Section 8.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

         On and after the time the Servicer receives a notice of termination
pursuant to Section 8.01, the Trustee shall automatically become the successor
to the Servicer with respect to the transactions set forth or provided for
herein and after a transition period (not to exceed 90 days), 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 Article VI hereof except as otherwise
provided herein; provided, however, that the Trustee's obligation to make
Advances in its capacity as Successor Servicer shall not be subject to such 90
day transition period and the Trustee in such capacity will make any Advance
required to be made by the predecessor Servicer on the Distribution Date on
which the predecessor Servicer was required to make such Advance. Effective on
the date of such notice of termination, as compensation therefor, the Trustee
shall be entitled to all fees, costs and expenses relating to the Mortgage Loans
that the terminated Servicer would have been entitled to if it had continued to
act hereunder, provided, however, that the Trustee shall not be (i) liable for
any acts or omissions of the terminated Servicer, (ii) obligated to make
Advances if it is prohibited from doing so under applicable law or determines
that such Advance, if made, would constitute a Nonrecoverable Advance, (iii)
responsible for expenses of the terminated Servicer pursuant to Section 2.03 or
(iv) obligated to deposit losses on any Permitted Investment directed by the

                                     -115-
<PAGE>

terminated Servicer. Notwithstanding the foregoing, the Trustee may, if it shall
be unwilling to so act, or shall, if it is prohibited by applicable law from
making Advances pursuant to Article VI 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 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 (i) be an institution that 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 (ii) be willing to act as successor servicer
of any Mortgage Loans under this Agreement and shall have executed and delivered
to the Depositor and the Trustee an agreement accepting such delegation and
assignment, that contains an assumption by such Person of the rights, powers,
duties, responsibilities, obligations and liabilities of the terminated Servicer
(other than any liabilities of the terminated Servicer hereof incurred prior to
termination of the Servicer under Section 8.01), with like effect as if
originally named as a party to this Agreement, provided that each Rating Agency
shall have acknowledged in writing 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. If the Trustee assumes
the duties and responsibilities of the Servicer in accordance with this Section
8.02, the Trustee shall not resign as Servicer until a Successor Servicer has
been appointed and has accepted such appointment. Pending appointment of a
successor to the terminated Servicer hereunder, the Trustee, unless the Trustee
is prohibited by law from so acting, shall, subject to Section 4.04 hereof, act
in such capacity as hereinabove provided. In connection with such appointment
and assumption, the Trustee may make such arrangements for the compensation of
such successor out of payments on Mortgage Loans or otherwise as it and such
successor shall agree; provided that no such compensation shall be in excess of
that permitted the terminated Servicer hereunder. The Trustee and such successor
shall take such action, consistent with this Agreement as shall be necessary to
effectuate any such succession. Neither the Trustee nor any other Successor
Servicer shall be deemed to be in default hereunder by reason of any failure to
make, or any delay in making, any distribution hereunder or any portion thereof
or any failure to perform, or any delay in performing, any duties or
responsibilities hereunder, in either case caused by the failure of the Servicer
to deliver or provide, or any delay in delivering or providing, any cash,
information, documents or records to it.

         The costs and expenses of the Trustee in connection with the
termination of the Servicer, appointment of a Successor Servicer and, if
applicable, any transfer of servicing, including, without limitation, all costs
and 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 Trustee to correct any errors or insufficiencies in the servicing data or
otherwise to enable the Trustee or the Successor Servicer to service the
Mortgage Loans properly and effectively, to the extent not paid by the
terminated Servicer as may be required herein, shall be payable to the Trustee
from the Distribution Account pursuant to Section 4.07. Any successor to the
terminated Servicer as successor servicer under this Agreement shall give notice
to the applicable Mortgagors of such change of servicer and shall, during the
term of its service as successor servicer maintain in force the policy or
policies that the terminated Servicer is required to maintain pursuant to
Section 3.04.

         Section 8.03 NOTIFICATION TO CERTIFICATEHOLDERS.

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

         (b) Within 60 days after the occurrence of any Servicer Default, the
Trustee shall transmit by mail to all Certificateholders notice of each the
Servicer Default hereunder known to the Trustee, unless such default shall have
been cured or waived.

         Section 8.04 WAIVER OF SERVICER DEFAULTS.

         The Trustee may waive only by written notice from Certificateholders
evidencing 66-2/3 of the Voting Rights (unless such default materially and
adversely affects all Certificateholders, in which case the written direction
shall be from all of the Certificateholders) any default by the Servicer in the
performance of its obligations hereunder and its consequences. Upon any such
waiver of a past default, such default shall cease to exist, and any Servicer
Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived in writing.

                    CONCERNING THE TRUSTEE AND THE CUSTODIAN

         Section 9.01 DUTIES OF TRUSTEE.

         (a) The Trustee, prior to the occurrence of a Servicer Default, and
after the curing or waiver of all Servicer Defaults, which may have occurred
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement as duties of the Trustee. If a Servicer Default has
occurred and has not been cured or waived, the Trustee shall exercise such of
the rights and powers vested in it by this Agreement, and the same degree of
care and skill in their exercise, as a prudent person would exercise under the
circumstances in the conduct of such Person's own affairs.

         (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee pursuant to any provision of this
Agreement, the Trustee shall examine them to determine whether they are in the
form required by this Agreement; provided, however, that the Trustee shall not
be responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Servicer.

         (c) On each Distribution Date, the Trustee shall make monthly
distributions and the final distribution to the Certificateholders from funds in
the Distribution Account as provided in Sections 5.04, 5.06 and 10.01 based the
applicable Remittance Report.

         (d) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct; provided, however, that:

                  (i) Prior to the occurrence of a Servicer Default and after
         the curing or waiver of all the Servicer Defaults which may have
         occurred with respect to the Trustee, the duties and obligations of the
         Trustee shall be determined solely by the express provisions of this
         Agreement, the Trustee shall not be liable except for the performance
         of their respective duties and obligations as are specifically set
         forth in this Agreement, no implied covenants or obligations shall be
         read into this Agreement against the Trustee and, in the absence of bad
         faith on the part of the Trustee, the Trustee may conclusively rely and
         shall be fully protected in acting or refraining from acting, as to the
         truth of the statements and the correctness of the opinions expressed
         therein, upon any certificates or opinions furnished to the Trustee and
         conforming to the requirements of this Agreement;

                  (ii) The Trustee shall not be liable in its individual
         capacity for an error of judgment made in good faith by a Responsible
         Officer or Responsible Officers of the Trustee unless it shall be
         proved that the Trustee was negligent in ascertaining the pertinent
         facts;

                  (iii) The Trustee shall not be liable with respect to any
         action taken, suffered or omitted to be taken by it in good faith and
         believed by it to be authorized or within the

                                     -118-
<PAGE>

         rights or powers conferred upon it by this Agreement or in accordance
         with the directions of the Holders of Certificates evidencing not less
         than 25% of the aggregate Voting Rights of the Certificates, if such
         action or non-action relates to the time, method and place of
         conducting any proceeding for any remedy available to the Trustee or
         exercising any trust or other power conferred upon the Trustee under
         this Agreement;

                  (iv) The Trustee shall not be required to take notice or be
         deemed to have notice or knowledge of any default or Servicer Default
         unless a Responsible Officer of the Trustee shall have actual knowledge
         thereof. In the absence of such notice, the Trustee may conclusively
         assume there is no such default or Servicer Default;

                  (v) The Trustee shall not in any way be liable by reason of
         any insufficiency in any Account held by or in the name of Trustee
         unless it is determined by a court of competent jurisdiction that the
         Trustee's gross negligence or willful misconduct was the primary cause
         of such insufficiency (except to the extent that the Trustee is obligor
         and has defaulted thereon);

                  (vi) Anything in this Agreement to the contrary
         notwithstanding, in no event shall the Trustee be liable for special,
         indirect, punitive or consequential loss or damage of any kind
         whatsoever (including but not limited to lost profits), even if the
         Trustee has been advised of the likelihood of such loss or damage and
         regardless of the form of action and whether or not any such damages
         were foreseeable or contemplated; and

                  (vii) None of the Seller, the Depositor or the Trustee shall
         be responsible for the acts or omissions of the other, it being
         understood that this Agreement shall not be construed to render them
         partners, joint venturers or agents of one another.

The Trustee shall not be required to expend or risk its own funds or otherwise
incur liability, financial or otherwise, in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the terminated Servicer hereunder.

                  (e) All funds received by the Trustee and required to be
deposited in the Distribution Account pursuant to this Agreement will be
promptly so deposited by the Trustee.

         Section 9.02 CERTAIN MATTERS AFFECTING THE TRUSTEE.

         (a) Except as otherwise provided in Section 9.01:

                  (i) The Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting in reliance on any
         resolution or certificate of the Seller, the Depositor or the Servicer,
         any certificates 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;

<PAGE>

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

                  (iii) The Trustee shall not be under any obligation to
         exercise any of the trusts or powers vested in it by this Agreement,
         other than its obligation to give notices pursuant to this Agreement,
         or to institute, conduct or defend any litigation hereunder or in
         relation hereto at the request, order or direction of any of the
         Certificateholders pursuant to the provisions of this Agreement, unless
         such Certificateholders shall have offered to the Trustee reasonable
         security or indemnity satisfactory to it against the costs, expenses
         and liabilities which may be incurred therein or thereby. Nothing
         contained herein shall, however, relieve the Trustee of the obligation,
         upon the occurrence of a Servicer Default of which a Responsible
         Officer of the Trustee has actual knowledge (which has not been cured
         or waived), to exercise such of the rights and powers vested in it by
         this Agreement, and to use the same degree of care and skill in their
         exercise, as a prudent person would exercise under the circumstances in
         the conduct of his own affairs;

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

                  (v) The Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, approval, bond or other paper or document, unless requested in
         writing to do so by Holders of Certificates evidencing not less than
         25% of the aggregate Voting Rights of the Certificates and provided
         that the payment within a reasonable time to the Trustee of the costs,
         expenses or liabilities likely to be incurred by it in the making of
         such investigation is, in the opinion of the Trustee reasonably assured
         to the Trustee by the security afforded to it by the terms of this
         Agreement. The Trustee may require reasonable indemnity against such
         expense or liability as a condition to taking any such action. The
         reasonable expense of every such examination shall be paid by the
         Certificateholders requesting the investigation;

                  (vi) The Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or through
         Affiliates, nominees, custodians, agents or attorneys. The Trustee
         shall not be liable or responsible for the misconduct or negligence of
         any of the Trustee's agents or attorneys or paying agent appointed
         hereunder by the Trustee with due care;

                  (vii) Should the Trustee deem the nature of any action
         required on its part to be unclear, the Trustee may require prior to
         such action that it be provided by the Depositor with reasonable
         further instructions; the right of the Trustee to perform any
         discretionary act enumerated in this Agreement shall not be construed
         as a duty, and the Trustee shall not be accountable for other than its
         negligence or willful misconduct in the performance of any such act;

                                     -120-
<PAGE>

                  (viii) The Trustee shall not be required to give any bond or
         surety with respect to the execution of the trust created hereby or the
         powers granted hereunder;

                  (ix) The Trustee shall not have any duty to conduct any
         affirmative investigation as to the occurrence of any condition
         requiring the repurchase of any Mortgage Loan by any Person pursuant to
         this Agreement, or the eligibility of any Mortgage Loan for purposes of
         this Agreement; and

                  (x) The Trustee shall have no duty hereunder with respect to
         any complaint, claim, demand, notice or other document it may receive
         or which may be alleged to have been delivered or served upon it by the
         parties as a consequence of the assignment of any Mortgage Loan
         hereunder; provided, however that the Trustee shall promptly remit to
         the Servicer upon receipt any such complaint, claim, demand, notice or
         other document (i) which is delivered to the Trustee at is Corporate
         Trust Office, (ii) of which a Responsible Officer has actual knowledge
         or (iii) which contains information sufficient to permit the Trustee to
         make a determination that the real property to which such document
         relates is a Mortgaged Property.

         (b) The Trustee is hereby directed by the Depositor to execute the Cap
Contract on behalf of the Trust Fund in the form presented to it by the
Depositor and shall have no responsibility for the contents of the Cap Contract,
including, without limitation, the representations and warranties contained
therein. Any funds payable by the Trustee under the Cap Contract at closing
shall be paid by the Depositor. Notwithstanding anything to the contrary
contained herein or in the Cap Contract, the Trustee shall not be required to
make any payments to the counterparty under the Cap Contract.

         Section 9.03 TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

         The recitals contained herein and in the Certificates (other than the
signature and authentication of the Trustee on the Certificates) shall be taken
as the statements of the Depositor, and the Trustee shall not have any
responsibility for their correctness. The Trustee does not make any
representation as to the validity or sufficiency of the Certificates (other than
the signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan except as expressly provided in Sections 2.02 and 2.06; provided,
however, that the foregoing shall not relieve the Custodian of the obligation to
review the Mortgage Files pursuant to Sections 2.02 and 2.05 of this Agreement.
The Trustee's signature and authentication (or authentication of its agent) on
the Certificates shall be solely in its capacity as Trustee and shall not
constitute the Certificates an obligation of the Trustee in any other capacity.
The Trustee shall not be accountable for the use or application by the Depositor
of any of the Certificates or of the proceeds of such Certificates, or for the
use or application of any funds paid to the Depositor with respect to the
Mortgage Loans. The Trustee (other than in its capacity as Custodian and on such
capacity, subject to the provisions of Section 2.06) shall not be responsible
for the legality or validity of this Agreement or any document or instrument
relating to this Agreement, the validity of the execution of this Agreement or
of any supplement hereto or instrument of further assurance, or the validity,
priority, perfection or sufficiency of the security for the Certificates issued
hereunder or intended to be issued hereunder. The Trustee shall not at any time
have any responsibility or liability for or with respect to the legality,
validity and

                                     -121-
<PAGE>

enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. The Trustee shall not have any responsibility for filing any
financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder or to record this Agreement.

         Section 9.04 TRUSTEE MAY OWN CERTIFICATES.

         The Trustee in its individual capacity or in any capacity other than as
Trustee hereunder may become the owner or pledgee of any Certificates with the
same rights it would have if it were not the Trustee and may otherwise deal with
the parties hereto.

         Section 9.05 TRUSTEE'S COMPENSATION AND EXPENSES; INDEMNIFICATION.

         (a) As compensation for the performance of its obligations under this
Agreement, the Trustee shall be entitled to all income and gain realized from
any investment of funds in the Distribution Account.

         In addition, the Trustee will be entitled to recover from the
Distribution Account pursuant to Section 4.07 all reasonable out-of-pocket
expenses, disbursements and advances and the expenses of the Trustee in
connection with the performance of its duties and obligations hereunder or under
any related documents, any Servicer Default, any breach of this Agreement or any
claim or legal action (including any pending or threatened claim or legal
action) incurred or made by the Trustee in the administration of the trusts
hereunder (including the reasonable compensation, expenses and disbursements of
its counsel) except any such expense, disbursement or advance as may arise from
its negligence or intentional misconduct. If funds in the Distribution Account
are insufficient therefor, the Trustee shall recover such expenses from the
Seller. Such compensation and reimbursement obligation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust. The rights of the Trustee under this Section 9.05 shall survive the
termination of this Agreement and the resignation or removal of the Trustee.

         (b) The Trustee and its directors, officers, agents and employees shall
be indemnified and held harmless by the Trust Fund against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever, including
reasonable attorney's fees, that may be imposed on, incurred by or asserted
against it or them in any way directly or indirectly relating to or arising out
of the transactions contemplated by this Agreement or any other agreement
entered into in connection herewith, including, but not limited to, the Mortgage
Loan Purchase Agreement assigned to the Trust pursuant to this Agreement or any
action taken or not taken by it or them hereunder or in connection herewith
except to the extent caused by the Trustee's negligence or willful misconduct.
The indemnification provided for under this Section 9.05 shall survive the
termination of this Agreement and the resignation or removal of the Trustee.

         The Trustee and its directors, officers, agents and employees shall be
indemnified and held harmless by the Trust Fund from and against any and all
claims, demands, losses, penalties,

                                     -122-
<PAGE>

liabilities, costs, damages, injuries and expenses, including, without
limitation, reasonable attorneys' fees and expenses, suffered or sustained by
the Trustee, either directly or indirectly, relating to or arising out of any
environmental law or regulation of the United States or any state thereof,
including, without limitation, any judgment, award, settlement, reasonable
attorneys' fees and expenses and other costs or expenses incurred in connection
with the defense of any actual or threatened action, proceeding or claim.

         Section 9.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

         The Trustee and any successor Trustee shall during the entire duration
of this Agreement be a state bank or trust company or a national banking
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 and undivided profits of at least
$40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to
supervision or examination by federal or state authority and, in the case of the
Trustee, rated "BBB" or higher by Fitch Ratings with respect to their long-term
rating and rated "A-1" or higher by Standard & Poor's and "Baa2" or higher by
Moody's with respect to any outstanding long-term unsecured unsubordinated debt,
and, in the case of a successor Trustee other than pursuant to Section 9.10,
rated in one of the two highest long-term debt categories of, or otherwise
acceptable to, each of the Rating Agencies. If the Trustee 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 9.06 the combined capital and surplus of such corporation shall be
deemed to be its total equity capital (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 9.06, the Trustee shall resign immediately in the manner and with the
effect specified in Section 9.08.

         Section 9.07 INSURANCE.

         The Custodian hereunder, at its own expense, shall at all times
maintain and keep in full force and effect such insurance in amounts, with
standard coverage and subject to deductibles, as are customary for insurance
typically maintained by banks which act as custodians but, in any event not less
than that required by Fannie Mae. Evidence of such insurance shall be furnished
to any Certificateholder upon reasonable written request.

         Section 9.08 RESIGNATION AND REMOVAL OF TRUSTEE.

         The Trustee may at any time resign and be discharged from the Trust
hereby created by giving written notice thereof to the Depositor and the Seller,
with a copy to the Rating Agencies. Upon receiving such notice of resignation,
the Depositor shall promptly appoint a successor trustee by written instrument,
in triplicate, one copy of which instrument shall be delivered to the resigning
trustee and the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation or removal, the resigning or removed 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 9.06 hereof and shall fail to resign after
written request thereto by the Depositor, (ii)

                                     -123-
<PAGE>

the Trustee shall become incapable of acting, or shall be adjudged as bankrupt
or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, or (iii)(A) a tax is imposed with respect to the Trust Fund by any
state in which the Trustee or the Trust Fund is located, (B) the imposition of
such tax would be avoided by the appointment of a different trustee and (C) the
Trustee fails to indemnify the Trust Fund against such tax, then the Depositor
may remove the Trustee and appoint a successor trustee by written instrument, in
multiple copies, a copy of which instrument shall be delivered to the Trustee
and the successor trustee.

         The Holders evidencing at least 51% of the Voting Rights of each Class
of Certificates may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in multiple copies, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered by the successor trustee to the Trustee so
removed and the successor trustee so appointed. Notice of any removal of the
Trustee shall be given to each Rating Agency by the Trustee or successor
trustee.

         Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 9.08 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 10.09 hereof.

         Section 9.09 SUCCESSOR TRUSTEE.

         Any successor trustee appointed as provided in Section 9.08 hereof
shall execute, acknowledge and deliver to the Depositor and to its predecessor
trustee 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 9.09 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 9.07 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 9.09, the successor trustee shall mail notice of the succession of
such trustee hereunder to all Holders of Certificates. If the successor trustee
fails to mail such notice within ten days after acceptance of appointment, the
Depositor shall cause such notice to be mailed at the expense of the Trust Fund.

         Section 9.10 MERGER OR CONSOLIDATION OF TRUSTEE.

         Any corporation, state bank or national banking association into which
the Trustee may be merged or converted or with which it may be consolidated or
any corporation, state bank or national banking association resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation, state bank or national banking association succeeding to
substantially all of the corporate trust business of the Trustee or shall be the

                                     -124-
<PAGE>

successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 9.06 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.

         Section 9.11 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 Trustee shall have the power and shall execute and deliver
all instruments to appoint one or more Persons approved by the Trustee 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 9.11, such
powers, duties, obligations, rights and trusts as the Trustee may consider
necessary or desirable. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
9.06 and no notice to Certificateholders of the appointment of any co-trustee or
separate trustee shall be required under Section 9.09.

         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 as
         Successor Servicer under this Agreement to advance funds on behalf of
         the terminated 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 a Trustee hereunder or as a Successor 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 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 IX. 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

                                     -125-
<PAGE>

this Agreement relating to the conduct of, affecting the liability of, or
affording protection to, the Trustee. Every such instrument shall be filed with
the Trustee and a copy thereof given to the Depositor. The Trust Fund shall pay
associated fees and expenses.

         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 9.12 TAX MATTERS.

         It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC formed hereunder
qualifies as, a "real estate mortgage investment conduit" as defined in and in
accordance with the REMIC Provisions. In furtherance of such intention, the
Trustee covenants and agrees that it shall act as agent (and the Trustee is
hereby appointed to act as agent) on behalf of the Trust Fund. The Trustee, as
agent on behalf of the Trust Fund, shall do or refrain from doing, as
applicable, the following: (a) the Trustee shall prepare and file, or cause to
be prepared and filed, in a timely manner, U.S. Real Estate Mortgage Investment
Conduit Income Tax Returns (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
such REMIC 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)
the Trustee shall apply for an employer identification number with the Internal
Revenue Service via a Form SS-4 or other comparable method for each REMIC that
is or becomes a taxable entity, and 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 the Trust Fund; (c) the Trustee
shall make or cause to be made elections, on behalf of each REMIC formed
hereunder to be treated as a REMIC on the federal tax return of such REMIC for
its first taxable year (and, if necessary, under applicable state law); (d) the
Trustee shall prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary, state
tax authorities, all information returns and reports as and when required to be
provided to them in accordance with the REMIC Provisions, including without
limitation, the calculation of any original issue discount using the Prepayment
Assumption; (e) the Trustee shall provide information necessary for the
computation of tax imposed on the transfer of a Residual 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) the
Trustee shall, to the extent under its

                                     -126-
<PAGE>

control, conduct the affairs of the Trust Fund at all times that any
Certificates are outstanding so as to maintain the status of each REMIC formed
hereunder as a REMIC under the REMIC Provisions; (g) the Trustee shall not
knowingly or intentionally take any action or omit to take any action that would
cause the termination of the REMIC status of any REMIC formed hereunder; (h) the
Trustee shall pay, from the sources specified in the last paragraph of this
Section 9.12, the amount of any federal, state and local taxes, including
prohibited transaction taxes as described below, imposed on any REMIC formed
hereunder prior to the termination of the Trust Fund when and as the same shall
be due and payable (but such obligation shall not prevent the Trustee or any
other appropriate Person from contesting any such tax in appropriate proceedings
and shall not prevent the Trustee from withholding payment of such tax, if
permitted by law, pending the outcome of such proceedings); (i) the Trustee
shall sign or cause to be signed federal, state or local income tax or
information returns or any other document prepared by the Trustee pursuant to
this Section 9.12 requiring a signature thereon by the Trustee; (j) the Trustee
shall maintain records relating to each REMIC formed hereunder including but not
limited to the income, expenses, assets and liabilities of each such REMIC 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; (k) the Trustee shall, for federal income
tax purposes, maintain books and records with respect to the REMICs on a
calendar year and on an accrual basis; (l) the Trustee shall not enter into any
arrangement not otherwise provided for in this Agreement by which the REMICs
will receive a fee or other compensation for services nor permit the REMICs to
receive any income from assets other than "qualified mortgages" as defined in
Section 860G(a)(3) of the Code or "permitted investments" as defined in Section
860G(a)(5) of the Code; and (m) as and when necessary and appropriate, the
Trustee shall represent the Trust Fund 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
REMIC formed hereunder, enter into settlement agreements with any governmental
taxing agency, extend any statute of limitations relating to any tax item of the
Trust Fund, and otherwise act on behalf of each REMIC formed hereunder in
relation to any tax matter involving any such REMIC.

         In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order to
enable the Trustee to perform its duties as set forth herein. The Depositor
hereby indemnifies the Trustee for any losses, liabilities, damages, claims or
expenses of the Trustee arising from any errors or miscalculations of the
Trustee that result from any failure of the Depositor to provide, or to cause to
be provided, accurate information or data to the Trustee on a timely basis.

         In the event that any tax is imposed on "prohibited transactions" of
any REMIC as defined in Section 860F(a)(2) of the Code, on the "net income from
foreclosure property" of the Trust Fund as defined in Section 860G(c) of the
Code, on any contribution to any REMIC after the startup day pursuant to Section
860G(d) of the Code, or any other tax is imposed, including,

                                     -127-
<PAGE>

without limitation, any federal, state or local tax or minimum tax imposed upon
any REMIC and is not paid as otherwise provided for herein, such tax shall be
paid by (i) the Trustee, if any such other tax arises out of or results from a
breach by the Trustee of any of its obligations under this Section, (ii) any
party hereto (other than the Trustee) to the extent any such other tax arises
out of or results from a breach by such other party of any of its obligations
under this Agreement or (iii) in all other cases, or in the event that any
liable party hereto fails to honor its obligations under the preceding clauses
(i) or (ii), any such tax will be paid first with amounts otherwise to be
distributed to the Residual Certificateholders, and second with amounts
otherwise to be distributed to all other Certificateholders in the following
order of priority: first, to the Subordinate Certificates in reverse numerical
order, and second, to the Senior Certificates (pro rata based on the amounts to
be distributed). Notwithstanding anything to the contrary contained herein, to
the extent that such tax is payable by the Holder of any Certificates, the
Trustee is hereby authorized to retain on any Distribution Date, from the
Holders of the Residual Certificates (and, if necessary, second, from the
Holders of the other Certificates in the priority specified in the preceding
sentence), funds otherwise distributable to such Holders in an amount sufficient
to pay such tax. The Trustee shall include in its Remittance Report instructions
as to distributions to such parties taking into account the priorities described

                                   TERMINATION

         Section 10.01 TERMINATION UPON LIQUIDATION OR REPURCHASE OF ALL
                       MORTGAGE LOANS.

         Subject to Section 10.03, the obligations and responsibilities of the
Depositor, the Seller and the Trustee created hereby with respect to the Trust
Fund shall terminate upon the earlier of (a) the later to occur of the Class X
Certificateholder's (so long as it is not an affiliate of the Seller) exercise
of its optional right to purchase the Mortgage Loans and related REO Properties
(the "Clean-up Call") and (b) the later of (i) the maturity or other liquidation
(or any Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and the disposition of all REO Property and (ii) the distribution to
Certificateholders of all amounts required to be distributed to them pursuant to
this Agreement, as applicable. In no event shall the trusts created hereby
continue beyond the earlier of (i) the expiration of 21 years from the death of
the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador
of the United States to the Court of St. James, living on the date hereof and
(ii) the Latest Possible Maturity Date.

         The Cleanup Call shall be exercisable at a price (the "Termination
Price") equal to the sum of (i) 100% of the Stated Principal Balance of Mortgage
Loan, (ii) accrued interest thereon at the applicable Mortgage Rate to, but not
including, the first day of the month of such purchase, (iii) the appraised
value of any related REO Property (up to the Stated Principal Balance of the
related Mortgage Loan), such appraisal to be conducted by an appraiser mutually
agreed upon by the Class X Certificateholder and the Trustee and (iv)
unreimbursed out-of-pocket costs of the Servicer or the Trustee, including
unreimbursed servicing advances and the principal portion of any unreimbursed
Advances, made on the related Mortgage Loans prior to the exercise of such
repurchase right and (v) any unreimbursed costs and expenses of the Trustee
payable pursuant to Section 9.05.

         The right to exercise the Cleanup Call pursuant to the preceding
paragraph shall be exercisable if the Stated Principal Balance of all of the
Mortgage Loans at the time of any such repurchase, is less than or equal to ten
percent of the aggregate Cut-off Date Principal Balance of the Mortgage Loans.

         Section 10.02 FINAL DISTRIBUTION ON THE CERTIFICATES.

         If on any Determination Date, (i) the Trustee determines based on the
reports delivered by the Servicer under this Agreement that there are no
Outstanding Mortgage Loans, and no other funds or assets in the Trust Fund other
than the funds in the Distribution Account, the Trustee shall to send a final
distribution notice promptly to each related Certificateholder or (ii) the
Trustee determines that a Class of Certificates shall be retired after a final
distribution on such Class, the Trustee shall notify the Certificateholders
within five (5) 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 related Certificates at the office of the
Trustee set forth herein. If the Class X

                                     -131-
<PAGE>

Certificateholder elects to terminate the Trust Fund pursuant to Section 10.01,
at least 20 days prior to the date notice is to be mailed to the
Certificateholders, the Class X Certificateholder shall notify the Trustee of
the date the Class X Certificateholder intends to terminate the Trust Fund. The
Class X Certificateholder shall remit the Termination Price to the Trustee on
the Business Day prior to the Distribution Date for such Optional Termination by
the Class X Certificateholder.

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

         In the event such notice is given, the Class X Certificateholder shall
deposit in the Distribution 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 and the receipt by the Trustee of a
Request for Release therefor, the Trustee shall promptly release to the Class X
Certificateholder, as applicable the Mortgage Files for the related Mortgage
Loans and any documents necessary to transfer any related REO Property.

         Upon presentation and surrender of the related Certificates, the
Trustee shall cause to be distributed to Certificateholders of each Class the
amounts allocable to such Certificates held in the Distribution Account in the
order and priority set forth in Section 5.04 and/or Section 5.06 hereof on the
final Distribution Date and in proportion to their respective Percentage
Interests.

         In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to the remaining affected Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all the applicable Certificates shall not
have been surrendered for cancellation, the Trustee may take appropriate steps,
or may appoint an agent to take appropriate steps, to contact the remaining
affected 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 two years after the second notice all affected
Certificates shall not have been surrendered for cancellation, the related
Residual Certificateholders shall be entitled to all unclaimed funds and other
assets of the Trust Fund that remain subject hereto and the Trustee shall
release such funds upon written direction.

         Section 10.03 ADDITIONAL TERMINATION REQUIREMENTS.

         (a) In the event of (i) the exercise by the Class X Certificateholder
of the Cleanup Call pursuant to the terms of this Agreement, or (ii) the final
payment on or other liquidation of the last Mortgage Loan or REO Property in the
related REMIC pursuant to Section 10.01, the following additional requirements,
unless the Trustee has been supplied with an Opinion of Counsel, at the expense
of the Class X Certificateholder (in the case of the exercise of the Cleanup
Call) or the Depositor, to the effect that the failure of the Trust Fund to
comply with the requirements of this Section 10.03 will not (i) result in the
imposition of taxes on "prohibited transactions" of a REMIC, or (ii) cause any
REMIC to fail to qualify as a REMIC at any time that any Certificates are
outstanding:

                  (1) The Class X Certificateholder (in the case of the exercise
         of the Cleanup Call) or the Depositor (in all other cases) shall
         establish a 90-day liquidation period and notify the Trustee thereof,
         and the Trustee shall in turn specify the first day of such period in a
         statement attached to the tax return for each of REMIC I and REMIC II
         pursuant to Treasury Regulation Section 1.860F-1. The Class X
         Certificateholder or the Depositor, as applicable, 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 Class X Certificateholder or the
         Depositor, as applicable;

                  (2) During such 90-day liquidation period, and at or prior to
         the time of making the final payment on the Certificates, the Class X
         Certificateholder (in the case of the exercise of the Cleanup Call) or
         the Depositor (in all other cases) shall sell all of the assets of
         REMIC I for cash; and

                  (3) At the time of the making of the final payment on the
         Certificates, the Trustee shall distribute or credit, or cause to be
         distributed or credited, to the Holders of the related Residual
         Certificates all cash on hand in the Trust Fund (other than cash
         retained to meet claims), and the Trust Fund shall terminate at that
         time.

         (b) By their acceptance of the Certificates, the Holders thereof hereby
authorize the Class X Certificateholder (in the case of the exercise of the
Cleanup Call) or the Depositor (in all other cases) to specify the 90-day
liquidation period for REMIC I and REMIC II, which authorization shall be
binding upon all successor Certificateholders.

         (c) The Trustee as agent for each REMIC hereby agrees to adopt and sign
such a plan of complete liquidation upon the written request of the Class X
Certificateholder or the Depositor, as applicable, and the receipt of the
Opinion of Counsel referred to in Section 10.03(a)(1) and to take such other
action in connection therewith as may be reasonably requested by the Class X
Certificateholder or the Depositor, as applicable.

                            MISCELLANEOUS PROVISIONS

         Section 11.01 AMENDMENT.

         This Agreement may be amended from time to time by parties hereto,
without the consent of any of the Certificateholders to cure any ambiguity, to
correct or supplement any provisions herein, to change the manner in which the
Distribution Account maintained by the Trustee or the Custodial Account are
maintained or to make such other provisions with respect to matters or questions
arising under this Agreement as shall not be inconsistent with any other
provisions herein if such action shall not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder; provided that any such amendment shall be deemed not to
adversely affect in any material respect the interests of the Certificateholders
and no such Opinion of Counsel shall be required if the Person requesting such
amendment obtains a letter from each Rating Agency stating that such amendment
would not result in the downgrading or withdrawal of the respective ratings then
assigned to the Certificates.

         Notwithstanding the foregoing, without the consent of the
Certificateholders, the parties hereto 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 each of REMIC I and REMIC II as a REMIC under the Code or to avoid or
minimize the risk of the imposition of any tax on either REMIC I or REMIC II
pursuant to the Code that would be a claim against REMIC I or REMIC II at any
time prior to the final redemption of the Certificates, provided that the
Trustee has been provided an Opinion of Counsel, which opinion shall be an
expense of the party requesting such opinion but in any case shall not be an
expense of the Trustee or the Trust Fund, 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 parties
hereto and the Holders of each Class of Certificates affected thereby evidencing
over 50% of the Voting Rights of such Class or Classes 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 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) cause
either REMIC I or REMIC II to cease to qualify as a REMIC or (iii) reduce the
aforesaid percentages of Certificates of each Class the Holders of which are
required to consent to any such amendment without the consent of the Holders of
all Certificates of such Class 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, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not (other than an

                                     -134-
<PAGE>

amendment pursuant to clause (ii) of, and in accordance with, the preceding
paragraph) cause the imposition of any tax on REMIC I or REMIC II or the
Certificateholders or cause REMIC I or REMIC II to cease to qualify as a REMIC
at any time that any Certificates are outstanding. Further, nothing in this
Agreement shall require the Trustee to enter into an amendment without receiving
an Opinion of Counsel, satisfactory to the Trustee that (i) such amendment is
permitted and is not prohibited by this Agreement and (ii) that all requirements
for amending this Agreement (including any consent of the applicable
Certificateholders) have been complied with.

         Promptly after the execution of any amendment to this Agreement
requiring the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder and
each Rating Agency.

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

         Section 11.02 RECORDATION OF AGREEMENT; COUNTERPARTS.

         To the extent permitted by applicable law, this Agreement is subject to
recordation in all appropriate public offices for real property records in all
of the counties or other comparable jurisdictions in which any or all of the
Mortgaged Properties are situated, and in any other appropriate public recording
office or elsewhere. The Seller or the Depositor shall effect such recordation
at the Trust's expense upon the request in writing of a Certificateholder, but
only if such direction is accompanied by an Opinion of Counsel (provided at the
expense of the Certificateholder requesting recordation) to the effect that such
recordation would materially and beneficially affect the interests of the
Certificateholders or is required by law.

         For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, 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 11.03 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 11.04 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

                                     -135-
<PAGE>

and/or assumption agreements and private mortgage insurance policies relating to
the Mortgage Loans by the Seller to the Depositor, and by the Depositor to the
Trust Fund be, and be construed as, an absolute sale thereof to the Depositor or
the Trust Fund, as applicable. It is, further, not the intention of the parties
that such conveyance be deemed a pledge thereof by the Seller to the Depositor,
or by the Depositor to the Trust Fund. However, in the event that,
notwithstanding the intent of the parties, such assets are held to be the
property of the Seller or the Depositor, as applicable, 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) each conveyance provided for in this Agreement shall be deemed to be an
assignment and a grant by the Seller or the Depositor, as applicable, for the
benefit of the Certificateholders, of a security interest in all of the assets
that constitute the Trust Fund, whether now owned or hereafter acquired.

         The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement.

         Section 11.05 NOTICES.

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, or to obtain or seek
to obtain priority over or preference to any other such Holder 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 11.08, each and every Certificateholder or the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

         Section 11.09 CERTIFICATES NONASSESSABLE AND FULLY PAID.

         It is the intention of the Depositor that Certificateholders shall not
be personally liable for obligations of the Trust Fund, that the interests in
the Trust Fund represented by the Certificates shall be nonassessable for any
reason whatsoever, and that the Certificates, upon due authentication thereof by
the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [I][II]-A[-1][-2][-3] Certificates with respect
         to a Trust Fund consisting primarily of a pool of conventional one- to
         four-family adjustable interest rate mortgage loans sold by NOMURA
         ASSET ACCEPTANCE CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, adjustable rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as servicer, and JPMorgan Chase Bank, N.A., as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of

                                      A-1-2

<PAGE>

which is set forth hereafter. To the extent not defined herein, capitalized
terms used herein shall have the meaning ascribed to them in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of its acceptance hereof assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during [for Class
I-A[-1][-2] Certificates: the calendar month prior to the calendar month in
which a Distribution Date (as hereinafter defined) occurs] [for Class II-A-1,
Class II-A-2 and Class II-A-3 Certificates: the period commencing on the
immediately preceding Distribution Date (as hereinafter defined) (or with
respect to the First Distribution Date, the Closing Date) and ending on the day
immediately preceding the related Distribution Date] on the Certificate
Principal Balance hereof at a per annum Pass-Through Rate equal to [for Class
I-A-1 Certificates: the weighted average of the Net Mortgage Rates of the Group
I Mortgage Loans minus [__]%][for Class I-A-2 Certificates: the weighted average
of the Net Mortgage Rates of the Group I Mortgage Loans minus [__]%] [for Class
II-A-1, Class II-A-2 and Class II-A-3 Certificates: the least of (i) the sum of
one-month LIBOR for that Distribution Date plus (A) on or prior to the first
possible optional termination date, [___]% or (B) after the first possible
optional termination date, [__]%, (ii) the applicable Net Funds Cap, (iii) the
applicable Cap Rate and (iv) the applicable Maximum Interest Rate]. The Trustee
will distribute on the 25th day of each month, or, if such 25th day is not a
Business Day, the immediately following Business Day (each, a "Distribution
Date"), commencing on the First Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on [for
Class I-A-1 and I-A-2 Certificates: the last day (or if such last day is not a
Business Day, the Business Day immediately preceding such last day) of the
calendar month immediately preceding the month in which the Distribution Date
occurs][for Class II-A-1, Class II-A-2 and Class II-A-3 Certificates: the
Business Day immediately preceding such Distribution Date], an amount equal to
the product of the Percentage Interest evidenced by this Certificate and the
amount (of interest and principal, if any) required to be distributed to the
Holders of Certificates of the same Class as this Certificate. The Assumed Final
Distribution Date is the Distribution Date in the month following the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Certificate Principal Balance of this Class of Certificates will be
reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon [for Class I-A-2 and Class II-A-3
Certificates: and Realized Losses on the Group I and II Mortgage Loans allocable
to the [Class I-A2] [Class II-A-3] Certificates].

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

<PAGE>

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

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee. The Certificates are limited in right of
payment to certain collections and recoveries respecting the Mortgage Loans and
payments received pursuant to the Cap Contracts, all as more specifically set
forth in the Agreement.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Classes or Classes of Certificates affected thereby evidencing
over 50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Trustee or any such agent shall be affected
by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other

                                      A-1-4

<PAGE>

liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only if on such Distribution Date the aggregate Stated
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.
The exercise of such right will effect the early retirement of the Certificates.
In no event, however, will the Trust Fund created by the Agreement continue
beyond the earlier to occur of (i) expiration of 21 years after the death of
certain persons identified in the Agreement and (ii) the Assumed Final
Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                        MORTGAGE PASS-THROUGH CERTIFICATE
                                 SERIES 2005-AR1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class M-[1][2][3][4][5] Certificates with respect to a
         Trust Fund consisting primarily of a pool of conventional one- to
         four-family adjustable interest rate mortgage loans sold by NOMURA
         ASSET ACCEPTANCE CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by NAAC or the Trustee or
any of their affiliates or any other person. None of NAAC, the Trustee or any of
their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, adjustable rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the
"Seller") to NAAC. The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among NAAC, as depositor (the "Depositor"), the Seller, as seller,
GMAC Mortgage Corporation, as servicer, and JPMorgan Chase Bank, N.A., as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, capitalized
terms used herein shall have the meaning ascribed to them in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder

                                     A-2-2

<PAGE>

of this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the period
commencing on the immediately preceding Distribution Date (as hereinafter
defined) (or with respect to the First Distribution Date, the Closing Date) and
ending on the day immediately preceding the related Distribution Date on the
Certificate Principal Balance hereof at a per annum Pass-Through Rate equal to
the least of (i) the sum of one-month LIBOR for that Distribution Date plus (A)
on or prior to the first possible optional termination date, [___]% or (B) after
the first possible optional termination date, [__]%, (ii) the applicable Net
Funds Cap, (iii) the applicable Cap Rate and (iv) the applicable Maximum
Interest Rate. The Trustee will distribute on the 25th day of each month, or, if
such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the Business Day immediately preceding such
Distribution Date, an amount equal to the product of the Percentage Interest
evidenced by this Certificate and the amount (of interest and principal, if any)
required to be distributed to the Holders of Certificates of the same Class as
this Certificate. The Assumed Final Distribution Date is the Distribution Date
in the month following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Certificate Principal Balance of
this Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee. The Certificates are limited in right of
payment to certain collections and recoveries respecting the Mortgage Loans and
payments received pursuant to the Cap Contracts, all as more specifically set
forth in the Agreement.

                  The Agreement permits, with certain exceptions therein
provided, the amendment

                                     A-2-3

<PAGE>

thereof and the modification of the rights and obligations of the Depositor and
the rights of the Certificateholders under the Agreement from time to time by
the parties thereto with the consent of the Holders of the Class or Classes of
Certificates affected thereby evidencing over 50% of the Voting Rights of such
Class or Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  Any transferee of this Certificate shall be deemed to make the
representations set forth in Section 6.02(b) of the Agreement.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only if on such Distribution Date the aggregate Stated
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.
The exercise of such right will effect the early retirement of the Certificates.
In no event, however, will the Trust Fund created by the Agreement continue
beyond the earlier to occur of (i) expiration of 21 years after the death of
certain persons identified in the Agreement and (ii) the Assumed Final
Distribution Date.

and the amount required to be distributed to the Holders of Certificates of the
same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month following the latest scheduled maturity date of
any Mortgage Loan.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the

                                     A-3-3

<PAGE>

Depositor nor the Trustee is obligated to register or qualify the Class of
Certificates specified on the face hereof under the 1933 Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Depositor and the Seller against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Certificate shall be made to any person
unless the transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and

                                     A-3-4

<PAGE>

subject to certain limitations therein set forth, this Certificate is
exchangeable for one or more new Certificates evidencing the same Class and in
the same aggregate Percentage Interest, as requested by the Holder surrendering
the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only if on such Distribution Date the aggregate Stated
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.
The exercise of such right will effect the early retirement of the Certificates.
In no event, however, will the Trust Fund created by the Agreement continue
beyond the earlier to occur of (i) expiration of 21 years after the death of
certain persons identified in the Agreement and (ii) the Assumed Final
Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class P Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         adjustable interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee referred to below or any of their
affiliates or any other person. Neither this Certificate nor the underlying
Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC
or the Trustee or any of their affiliates or any other person. None of NAAC, the
Trustee or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

                  This certifies that Nomura Securities International, Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund"), generally consisting of conventional
first lien, adjustable rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as

depositor (the "Depositor"), the Seller, as seller, GMAC Mortgage Corporation,
as servicer, and JPMorgan Chase Bank, N.A., as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor or the Trustee in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor and the Seller against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate shall be made to any person
unless the transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Trustee or any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination

                                     A-4-4

of the Agreement) shall terminate upon the earlier of (i) the later of (A) the
maturity or other liquidation (or Advance with respect thereto) of the last
Mortgage Loan remaining in the Trust Fund and disposition of all property
acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan
and (B) the remittance of all funds due under the Agreement, or (ii) the
optional repurchase by the party named in the Agreement of all the Mortgage
Loans and other assets of the Trust Fund in accordance with the terms of the
Agreement. Such optional repurchase may be made only on if on such Distribution
Date the aggregate Stated Principal Balance of the Mortgage Loans is less than
or equal to 10% of the aggregate Stated Principal Balance of the Mortgage Loans
at the Cut-off Date. The exercise of such right will effect the early retirement
of the Certificates. In no event, however, will the Trust Fund created by the
Agreement continue beyond the earlier to occur of (i) expiration of 21 years
after the death of certain persons identified in the Agreement and (ii) the
Assumed Final Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class R Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         adjustable interest rate mortgage loans sold by NOMURA ASSET ACCEPTANCE
         CORPORATION.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Nomura Asset
Acceptance Corporation ("NAAC") or the Trustee referred to below or any of their
affiliates or any other person. Neither this Certificate nor the underlying
Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC
or the Trustee or any of their affiliates or any other person. None of NAAC, the
Trustee or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

                  This certifies that Nomura Securities International, Inc. is
the registered owner of the Percentage Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund"), generally consisting of conventional
first lien, adjustable rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by NAAC. The Mortgage Loans were sold
by Nomura Credit & Capital, Inc. (the "Seller") to NAAC. The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among NAAC, as

                                     A-5-2

depositor (the "Depositor"), the Seller, as seller, GMAC Mortgage Corporation,
as servicer, and JPMorgan Chase Bank, N.A., as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Depositor will have the right, in
its sole discretion and without notice to the Holder of this Certificate, to
sell this Certificate to a purchaser selected by the Depositor, which purchaser
may be the Depositor, or any affiliate of the Depositor, on such terms and
conditions as the Depositor may choose.

                  The Trustee will distribute on the 25th day of each month, or,
if such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last day (or if such last day is not a Business
Day, the Business Day immediately preceding such last day) of the calendar month
immediately preceding the month in which the Distribution Date occurs, an amount
equal to the product of the Percentage Interest evidenced by this Certificate
and the amounts required to be distributed to the Holders of Certificates of the
same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month following the latest scheduled maturity date of
any Mortgage Loan.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made to any person
unless the transferee provides a certification pursuant to Section 6.02(b) of
the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Trustee or any such agent shall be affected

                                     A-5-4

by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only if on such Distribution Date the aggregate Stated
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.
The exercise of such right will effect the early retirement of the Certificates.
In no event, however, will the Trust Fund created by the Agreement continue
beyond the earlier to occur of (i) expiration of 21 years after the death of
certain persons identified in the Agreement and (ii) the Assumed Final
Distribution Date.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                           particular, in such matters related to securities
                           similar to the Certificates, such that it is capable
                           of evaluating the merits and risks of investment in
                           the Certificates, (b) able to bear the economic risks

                           opportunity to review (a) a copy of the Pooling and

                           the Seller to the satisfaction of the Purchaser.

                           any Certificate, any interest in any Certificate or

                           other similar security from any person in any manner,
                           (c) otherwise approach or negotiate with respect to
                           any Certificate, any interest in any Certificate or
                           any other similar security with any person in any
                           manner, (d) make any general solicitation by means of
                           general advertising or in any other manner or (e)
                           take any other action, that (as to any of (a) through
                           (e) above) would constitute a distribution of any
                           Certificate under the Act, that would render the
                           disposition of any Certificate a violation of Section
                           5 of the Act or any state securities law, or that
                           would require registration or qualification pursuant
                           thereto. The Purchaser will not sell or otherwise
                           transfer any of the Certificates, except in

                  "Certificates"), including the Class Certificates (the

                  ------------------------------------------------------------

Dear Ladies and Gentlemen:

         In connection with our purchase of Private Certificates, we confirm
that:

                  (i)      we understand that the Private Certificates are not
                           being registered under the Securities Act of 1933, as
                           amended (the "Act") or any applicable state
                           securities or "Blue Sky" laws, and are being sold to
                           us in a transaction that is exempt from the
                           registration requirements of such laws;

                  (ii)     any information we desired concerning the
                           Certificates, including the Private Certificates, the
                           trust in which the Certificates represent the entire
                           beneficial ownership interest (the "Trust") or any
                           other matter we deemed relevant to our decision to
                           purchase Private Certificates has been made available
                           to us;

                  (iii)    we are able to bear the economic risk of investment
                           in Private Certificates; we are an institutional
                           "accredited investor" as defined in Section 501(a) of
                           Regulation D promulgated under the Act and a
                           sophisticated institutional investor and we agree to
                           obtain a representation from any transferee that such
                           transferee is an institutional "accredited investor"
                           so long as we are required to obtain a representation
                           letter regarding compliance with the Act;

                                       G-1

<PAGE>

                  (iv)     we are acquiring Private Certificates for our own
                           account, not as nominee for any other person, and not
                           with a present view to any distribution or other
                           disposition of the Private Certificates;

                  (v)      we agree the Private Certificates must be held
                           indefinitely by us (and may not be sold, pledged,
                           hypothecated or in any way disposed of) unless
                           subsequently registered under the Act and any
                           applicable state securities or "Blue Sky" laws or an
                           exemption from the registration requirements of the
                           Act and any applicable state securities or "Blue Sky"
                           laws is available;

                  (vi)     we agree that in the event that at some future time
                           we wish to dispose of or exchange any of the Private
                           Certificates (such disposition or exchange not being
                           currently foreseen or contemplated), we will not
                           transfer or exchange any of the Private Certificates
                           unless:

                           (A) (1) the sale is to an Eligible Purchaser (as
                           defined below), (2) if required by the Pooling and

                           substantially the same effect as either this letter
                           or, if the Eligible Purchaser is a Qualified
                           Institutional Buyer as defined under Rule 144A of the
                           Act, the Rule 144A and Related Matters Certificate in
                           the form attached to the Pooling and Servicing
                           Agreement (as defined below) (or such other
                           documentation as may be acceptable to the Trustee) is
                           executed promptly by the purchaser and delivered to
                           the addressees hereof and (3) all offers or
                           solicitations in connection with the sale, whether
                           directly or through any agent acting on our behalf,
                           are limited only to Eligible Purchasers and are not
                           made by means of any form of general solicitation or
                           general advertising whatsoever; and

                           (B) if the Private Certificate is not registered
                           under the Act (as to which we acknowledge you have no
                           obligation), the Private Certificate is sold in a
                           transaction that does not require registration under
                           the Act and any applicable state securities or "blue
                           sky" laws and, if JPMorgan Chase Bank, N.A. (the
                           "Trustee") so requests, a satisfactory Opinion of
                           Counsel is furnished to such effect, which Opinion of
                           Counsel shall be an expense of the transferor or the
                           transferee;

                  (vii)    we agree to be bound by all of the terms (including
                           those relating to restrictions on transfer) of the
                           Pooling and Servicing, pursuant to which the Trust
                           was formed; we have reviewed carefully and understand
                           the terms of the Pooling and Servicing Agreement;

                  (viii)   we either: (i) are not acquiring the Privately
                           Offered Certificate directly or indirectly by, or on
                           behalf of, an employee benefit plan or other
                           retirement arrangement which is subject to Title I of
                           the Employee Retirement Income Security Act of 1974,

                           Section 6.02(b) of the Agreement.

                  (ix)     we understand that each of the Class ___ Certificates
                           bears, and will continue to bear, legends

APPENDIX E - STANDARD & POOR'S ANTI-PREDATORY LENDING CATEGORIZATION

Standard & Poor's has categorized loans governed by anti-predatory lending laws
in the Jurisdictions listed below into three categories based upon a combination
of factors that include (a) the risk exposure associated with the assignee
liability and (b) the tests and thresholds set forth in those laws. Note that
certain loans classified by the relevant statute as Covered are included in
Standard & Poor's High Cost Loan Category because they included thresholds and
tests that are typical of what is generally considered High Cost by the
industry.
