                                   DEFINITIONS

         Section 1.01 Defined Terms.

         In addition to those terms defined in Section 1.02, whenever used in
this Agreement, the following words and phrases, unless the context otherwise
requires, shall have the following meanings:

         ACCOUNT: Either a Distribution Account or a Custodial Account.

         ACCRUAL PERIOD: With respect to the Senior-Subordinate Certificates and
the Class V-X Certificates and any Distribution Date, the calendar month
immediately preceding such Distribution Date. With respect to the Group V
Certificates (other than the Class V-X Certificates) and any Distribution Date,
the period commencing on the immediately preceding Distribution Date (or with
respect to the first Accrual Period, the Closing Date) and ending on the day
immediately preceeding the related Distribution Date. All calculations of
interest on the Senior-Subordinate Certificates and the Class V-X Certificates
will be based on a 360-day year consisting of twelve 30-day months. All
calculations of interest on the Group V Certificates (other than the Class V-X
Certificates) will be made based on a 360-day year and the actual number of days
elapsed in the related Accrual Period.

         ACCRUED CERTIFICATE INTEREST: With respect to the Senior-Subordinate
Certificates for any Distribution Date, means an amount equal to the interest
accrued during the related Accrual Period at the applicable Pass-Through Rate on
the Certificate Principal Balance (or Class IV-X Notional Amount) of such
Certificate immediately prior to such Distribution Date less such Certificate's
share of any Net Interest Shortfall and the interest portion of any Realized
Losses on the related Mortgage Loans allocated to such Certificate pursuant to
Section 5.05. Accrued Certificate Interest is calculated on the basis of a
360-day year consisting of twelve 30-day months. No Accrued Certificate Interest
will be payable with respect to any Class of Senior-Subordinate Certificates
after the Distribution Date on which the outstanding Certificate Principal
Balance of such Certificate has been reduced to zero.

         For purposes of calculating the amount of the Accrued Certificate
Interest for the Senior-Subordinate Certificates (other than the Class R-I
Certificates) for any Distribution Date, Net Interest Shortfalls in respect of
the Mortgage Loans of a Senior-Subordinate Loan Group for any Distribution Date
shall be allocated pro rata among all such Classes of Certificates, and, if
applicable, the Group II Excess Interest Amount, related to such Loan Group,
based on the amount of interest each of those Classes of Certificates and the
Group II Excess Interest Amount, as applicable, would otherwise be entitled to
receive on that Distribution Date from such Loan Group before taking into
account any reduction in the amounts resulting from Net Interest Shortfalls.

         ADJUSTMENT DATE: With respect to each Mortgage Loan, the first day of
the month in which the Mortgage Rate of the Mortgage Loan changes pursuant to
the related Mortgage Note.

                                     - 7 -

set forth in the Loan Schedule.

         ADVANCE: An advance of delinquent payments of principal or interest in

Distribution Date, the aggregate of the Stated Principal Balances of the
Mortgage Loans in the related Loan Group as of the last day of the related Due
Period.

         AGGREGATE LOAN GROUP BALANCE: With respect to either Loan Group VA or
Loan Group VB and any Distribution Date, the aggregate of the Stated Principal
Balances of the Mortgage Loans in the related Loan Group as of the last day of
the related Due Period.

         AGREEMENT: This Pooling and Servicing Agreement and any and all
amendments or supplements hereto made in accordance with the terms herein.

         AMOUNT HELD FOR FUTURE DISTRIBUTION: As to any Distribution Date, the
aggregate amount held in a Custodial Account at the close of business on the
immediately preceding Determination Date on account of (i) all Scheduled
Payments or portions thereof received in respect of the related Mortgage Loans
due after the related Due Period and (ii) Principal Prepayments and Liquidation
Proceeds received in respect of such Mortgage Loans after the last day of the
related Prepayment Period.

         APPLIED LOSS AMOUNT: With respect to the Group V Certificates (other
than the Class V-X Certificates) and any Distribution Date, the excess of the
aggregate Certificate Principal Balance of the Group V Certificates (other than
the Class V-X Certificates) over the Aggregate Loan Balance of the Group V
Mortgage Loans after giving effect to all Realized Losses incurred with respect
to the Group V Mortgage Loans during the related Due Period and payments of
principal to the Group V Certificates (other than the Class V-X Certificates) on
such Distribution Date.

         APPRAISED VALUE: With respect to any Mortgage Loan originated in
connection with a refinancing, the appraised value of the Mortgaged Property
based upon the appraisal made at the time of such refinancing or, with respect
to any other Mortgage Loan, the lesser of (x) the appraised value of the

                            CONVEYANCE OF TRUST FUND
                         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.

                  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, as Trustee for certificateholders of
Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series
2004-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,
as Trustee for certificateholders of Nomura Asset Acceptance Corporation,
Mortgage Pass-Through Certificates, Series 2004-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

                                     - 65 -
<PAGE>

their delivery as specified above, the Depositor may deliver a true copy thereof
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 related 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.

         Section 2.02 ACCEPTANCE OF THE MORTGAGE LOANS.

                  (a) Based on the Initial Certification received by it from the
Custodian, the Trustee acknowledges receipt of, subject to the further review
and exceptions reported by the Custodian pursuant to the procedures described
below, the documents (or certified copies

                                     - 66 -
<PAGE>

thereof) delivered 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 in

                                     - 67 -
<PAGE>

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 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 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 related 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.

         with respect to indemnity and contribution under applicable securities
         law.

                  (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
         Seller and will not (A) result in a material breach of any term or
         provision of the charter or by-laws of the Seller 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 Seller 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 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
         instrument, or in violation of any statute, order or regulation of any

         having jurisdiction over it which breach or violation may materially

                  (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) and (ix) 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) and (ix) 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 (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

                                     - 72 -
<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 related 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 deposited into the related Distribution Account, by
the Seller delivering such Replacement Mortgage Loan on the Determination Date
for the Distribution Date relating to the Prepayment Period during which the
related Mortgage Loan became required to be purchased or replaced hereunder.

                  In the event that the Seller shall have repurchased a Mortgage
Loan, the Purchase Price therefor shall be deposited into the related
Distribution Account maintained by the Trustee, on the Determination Date for
the Distribution Date in the month following the month during

                                     - 73 -
<PAGE>

which the Seller became obligated to repurchase or replace such Mortgage Loan
and upon such deposit of the Purchase Price, 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

         terms, subject, as to enforceability, to (i) bankruptcy, insolvency,

         (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

                                     - 74 -
<PAGE>

         may be bound or (C) constitute a material violation of any statute,

         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

         terms hereof.

                  (v) No consent, approval, authorization or order of any court

         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

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, 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 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

                                     - 75 -

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.

                                   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, in connection with the waiver of a Prepayment Charge in respect
of the Group I-IV Mortgage Loans, or Class P-V Certificates, in connection with
the waiver of a Prepayment Charge in respect of the Group V Mortgage Loans, by
depositing such amount into the related 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 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

                                     - 80 -
<PAGE>

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 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

                                     - 81 -
<PAGE>

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 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 Accounts, 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

                                     - 82 -
<PAGE>

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 Accounts, shall be held by the Servicer for and on behalf of
the Trustee and shall be and remain the sole and exclusive property of the
Trustee, subject to the applicable provisions of this Agreement. The Servicer
also agrees that it shall not create, incur or subject any Mortgage File or any
funds that are deposited in the Custodial Accounts, the Distribution Accounts 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 related 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

                                     - 83 -
<PAGE>

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 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 related 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 related 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).

                                     - 84 -
<PAGE>

         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
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 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 related 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

                                     - 85 -
<PAGE>

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 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 related 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

                                     - 86 -
<PAGE>

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
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 related Custodial Account 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 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 related 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 Accounts shall be retained by the Servicer to the
extent not required to be deposited in the Custodial Accounts pursuant to
Section 4.02. The Servicer shall be required to pay all expenses incurred by it
in connection with its servicing activities hereunder

                                     - 87 -
<PAGE>

(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 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 related
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 2005 (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 believe 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 2005, a
certification containing the information set forth in Exhibit L. Such
certification shall be signed by the senior officer in charge of

                                     - 88 -

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 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 wilful 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 2005,
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 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

                                     - 90 -
<PAGE>

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 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 Accounts.

                  (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 related 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

                                     - 91 -
<PAGE>

expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the related 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 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

                                     - 92 -
<PAGE>

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, 2005 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 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.

<PAGE>

                  (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 Loans which as of the first day
of a Calendar Quarter 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 related 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 ACCOUNTS.

                  (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, 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 Mortgage Loan to extend to the maturity thereof.

                  (b) The Servicer shall establish and maintain segregated
Custodial Accounts (which shall at all times be Eligible Accounts) with a
depository institution in the name of the Servicer for the benefit of the
Trustee on behalf of the related Certificateholders and designated "JPMorgan
Chase Bank, as trustee for registered holders of Nomura Asset Acceptance
Corporation, Mortgage Pass-Through Certificates, Series
2004-AR1-Senior-Subordinate Certificates" and "JPMorgan Chase Bank, as trustee
for registered holders of Nomura Asset Acceptance Corporation, Mortgage
Pass-Through Certificates, Series 2004-AR1-Group V Certificates." 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 related 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 related
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 related Mortgage Loans;

                                     - 95 -
<PAGE>

                  (ii) all payments on account of interest on the related
         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 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 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; and

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

                  The foregoing requirements for deposit by the Servicer 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 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
related Custodial Account, to withdraw such amount from the related 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 related 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 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 or
other authorized entity shall invest the funds in the Custodial Accounts, 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 related 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 Accounts in respect of any such investments shall be deposited by the
Servicer into the related Custodial Account, out of its own funds.

                  (d) The Servicer 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 a Custodial Account prior to any change thereof.

         Section 4.02 PERMITTED WITHDRAWALS FROM THE CUSTODIAL ACCOUNTS.

                  (a) The Servicer may from time to time make withdrawals from a
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

         Insured Expenses covered by the related Insurance Policy;

         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;

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

                  In addition, no later than 3:00 p.m. Eastern time on the
Remittance Date, the Servicer shall withdraw from the Custodial Accounts and
remit to the Trustee (a) all amounts deposited in the Custodial Accounts as of
the close of business on the last day of the related Due Period (net of charges
against or withdrawals from the Custodial Accounts 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 Accounts 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 Accounts 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 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 the Servicer (including
any Successor Servicer) is less than "BBB", the Servicer shall be required to
replace such funds by deposit to the related 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.

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

                  Withdrawals of amounts so collected from the Escrow Accounts
may be made only to effect timely payment of taxes, assessments, hazard

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 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 ADJUSTMENTS TO MORTGAGE RATE AND SCHEDULED PAYMENT.

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 related Custodial
Account from its own funds the amount of any interest loss caused thereby
without reimbursement therefor.

this Agreement. The requirements for crediting the Distribution 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, 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 Accounts.

                  (c) The amount at any time credited to the Distribution

                           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 related 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 related 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 related Custodial
Account to the related Distribution Account. Any funds so applied and
transferred shall be replaced by the Servicer by deposit in the related
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 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 related 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
related 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, 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 related Custodial Account
all Advance Reimbursement Amounts. Notwithstanding the

                                    - 105 -
<PAGE>

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 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
related 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 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

                                    - 106 -

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 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 related 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

Section 5.04(C) below;

                           (d) fourth, to the extent of Available Funds

                           (e) fifth, to the extent of Available Funds remaining
after giving effect to the distributions set forth in clauses (a), (b), (c) and
(d) above, to the Class R-I Certificates, the remainder (which is expected to be

                  (ii) On each Distribution Date, the Senior Principal
Distribution Amount shall be distributed as follows:

                           (a) an amount, up to the amount of the Group I Senior
Principal Distribution Amount for that Distribution Date shall be distributed as
principal to the following Classes in the following order: (i) first, to the
Class R-I Certificates until its Certificate Principal Balance has been reduced
to zero; and (ii) second, to the Class I-A Certificates, until its Certificate
Principal Balance has been reduced to zero;

                           (b) On each Distribution Date, an amount, up to the

                                    - 108 -
<PAGE>

                           (c) On each Distribution Date, an amount, up to the
amount of the Group III Senior Principal Distribution Amount for that
Distribution Date, shall be distributed as principal to the Class III-A
Certificates, until its Certificate Principal Balance has been reduced to zero;
and

                           (d) On each Distribution Date, an amount, up to the
amount of the Group IV Senior Principal Distribution Amount for that
Distribution Date, shall be distributed as principal to the Class IV-A
Certificates, until its Certificate Principal Balance has been reduced to zero.

                  (iii) On each Distribution Date, the Subordinate Principal
Distribution Amount shall be distributed to the Class C-B-1, Class C-B-2, Class
C-B-3, Class C-B-4, Class C-B-5 and Class C-B-6 Certificates, in that order, in
an amount equal to such Class' pro rata share of the Subordinate Principal
Distribution Amount based on its respective Certificate Principal Balance, until
each Class of Group C-B Certificates has received its respective pro rata share
of the Subordinate Principal Distribution Amount for that Distribution Date;
provided, however, on any Distribution Date on which the Subordination Level for
any Class of Group C-B Certificates is less than the related Subordination Level
of such Class as of the Closing Date, no distributions of Principal Prepayments
in full or in part shall be made to any Class or Classes of Group C-B
Certificates junior to that Class. The amount otherwise distributable to those
Classes will be allocated among the remaining Classes of Group C-B Certificates,
pro rata, based upon their respective Certificate Principal Balances.

         (B) On each Distribution Date prior to the date upon which the
Certificate Principal Balances of the Group C-B Certificates is reduced to zero,
but after the date on which any of the aggregate Certificate Principal Balance
of the Group I, Group II, Group III or Group IV Certificates has been reduced to
zero, all Principal Funds relating to the Loan Group that has been paid in full,
will be paid to the Group I-IV Senior Certificates (other than the Class IV-X
Certificates) related to the other Senior-Subordinate Loan Groups. Such
Principal Funds will be allocated between the other Senior-Subordinate Loan
Groups, pro rata based on aggregate Certificate Principal Balance and paid to
the Group I-IV Senior Certificates (other than the Class IV-X Certificates)
related to such Loan Groups in the same priority as such Certificates would
receive other distributions of principal; provided that if, on any Distribution
Date (a) the Group C-B Percentage for that Distribution Date is greater than or
equal to 200% of that Group C-B Percentage as of the Closing Date and (b) the
average outstanding principal balance of the Mortgage Loans in each
Senior-Subordinate Loan Group delinquent 60 days or more over the last six
months, as a percentage of the related Group C-B Component Balance, is less than
50%, principal will not be distributed as described above.

         (C) If on any Distribution Date there exists an Undercollateralized
Group, the following will occur:

                  (i) the Available Funds in the Overcollateralized Group or
         Groups will be reduced, after distributions of interest to the Senior
         Certificates of each Overcollateralized Group in accordance with
         Section 5.04(A)(i)(a) above, in an aggregate amount equal to one
         month's interest on the Principal Transfer Amount of each
         Undercollateralized Group at the weighted average Pass-Through Rate
         applicable to the

                                    - 109 -
<PAGE>

         Undercollateralized Group or Groups and that amount will be added to
         the Available Funds of the applicable Undercollateralized Group; and

                  (ii) the portion of the Available Funds in respect of
         principal on the Mortgage Loans in the Overcollateralized Group or
         Groups, after distributions of principal to the Senior Certificates of
         each Overcollateralized Group in accordance with Section 5.04(A)
         (i)(b), will be distributed to the Senior Certificates of each
         Undercollateralized Group until the Certificate Principal Balance of
         the Senior Certificates of each Undercollateralized Group equals the
         Aggregate Loan Balance of the Mortgage Loans in the related Loan Group.

         In the event more than one Loan Group is an Overcollateralized Group on
any Distribution Date, reductions in the Available Funds of such Loan Groups to
make payment to the Undercollateralized Group or Groups will be made pro rata
based on the amount by which the aggregate Stated Principal Balance of the
Mortgage Loans in each such Overcollateralized Group exceeds the aggregate
Certificate Principal Balance of the Senior Certificates related to each such
Overcollateralized Group. In the event more than one Loan Group is an
Undercollateralized Group on any Distribution Date, payments made to such Loan
Groups from the Available Funds of the Overcollateralized Group will be made pro
rata based on the amount of payments required to be made to the
Undercollateralized Groups.

           (D) Subject to Section 10.02 hereof respecting the final distribution
on a Class of Certificates, on each Distribution Date the Trustee shall make
distributions to each Holder of a Group I-IV Certificate of record on the
preceding Record Date either by wire transfer in immediately available funds to
the account of such holder at a bank or other entity having appropriate
facilities therefor, if (i) such Holder has so notified the Trustee at least 5
Business Days prior to the related Record Date and (ii) such Holder shall hold
Regular Certificates with aggregate principal denominations of not less than
$1,000,000 or evidencing a Percentage Interest aggregating 10% or more with
respect to such Class or, if not, by check mailed by first class mail to such
Certificateholder at the address of such holder appearing in the Certificate
Register. Notwithstanding the foregoing, but subject to Section 10.02 hereof
respecting the final distribution, distributions with respect to Group I-IV
Certificates registered in the name of a Depository shall be made to such
Depository in immediately available funds.

         Section 5.05 ALLOCATION OF REALIZED LOSSES WITH RESPECT TO THE GROUP
                      I-IV MORTGAGE LOANS .

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

                  (b) Any Realized Loss with respect to a Group I-IV Mortgage
Loan, except for Excess Losses, will be allocated among the Senior-Subordinate
Certificates as follows:

                           (i) first, to the Class C-B-6 Certificates, until its
                           Certificate Principal Balance has been reduced to
                           zero;

                                    - 110 -
<PAGE>

                           (ii) second, to the Class C-B-5 Certificates, until
                           its Certificate Principal Balance has been reduced to
                           zero;

                           (iii) third, to the Class C-B-4 Certificates, until
                           its Certificate Principal Balance has been reduced to
                           zero;

                           (iv) fourth, to the Class C-B-3 Certificates, until
                           its Certificate Principal Balance has been reduced to
                           zero;

                           (v) fifth, to the Class C-B-2 Certificates, until its
                           Certificate Principal Balance has been reduced to
                           zero;

                           (vi) sixth, to the Class C-B-1 Certificates, until
                           its Certificate Principal Balance has been reduced to
                           zero; and

                           (vii) seventh, to the Senior Certificates of the
                           related Loan Group (other than the Class IV-X
                           Certificates), pro rata, according to and in
                           reduction of their Certificate Principal Balances.

                  (c) Accrued Certificate Interest for each Class of Group I-IV
Senior Certificates and the Group II Excess Interest Amounts will be reduced by
Net Interest Shortfalls on the Mortgage Loans in the related Loan Group for that
Distribution Date, and the Accrued Certificate Interest for the Group C-B
Certificates will be reduced by Net Interest Shortfalls on the Group I, Group
II, Group III and Group IV Mortgage Loans for that Distribution Date. Net
Interest Shortfalls on any Distribution Date will be allocated pro rata among
all such Classes of Certificates, and, if applicable, the Group II Excess
Interest Amount, related to such Loan Group, based on the amount of interest
each of those Classes of Certificates and the Group II Excess Interest Amount,
as applicable, would otherwise be entitled to receive on that Distribution Date
from such Loan Group before taking into account any reduction in the amounts
resulting from Net Interest Shortfalls. The amount a Class of Group C-B
Certificates would otherwise be entitled to receive from the Mortgage Loans in a
Loan Group before taking into account any such reduction will be based on the
amount of interest accruing at the applicable Net WAC Rate on that Class'
proportionate share, based on the Certificate Principal Balance, of the related
Group C-B Component Balance for that Distribution Date.

                  (d) On each Distribution Date, Excess Losses will be allocated
pro rata among the Classes of Senior-Subordinate Certificates (other than the
Class P Certificates and Class IV-X Certificates), based on their respective
Certificate Principal Balances.

                  (e) On each Distribution Date, if the aggregate Certificate
Principal Balance of all Classes of Group I-IV Certificates (other than the
Class IV-X Certificates) exceeds the Aggregate Loan Balance of the Group I,
Group II, Group III and Group IV Mortgage Loans after giving effect to
distributions of principal and the allocation of all losses to these
Certificates on that Distribution Date, that excess will be deemed a principal
loss and will be allocated to the most junior Class of Group C-B Certificates
then outstanding.

                  (f) Notwithstanding anything to the contrary contained herein,
if on any Distribution Date the Trustee discovers, based solely on the reports
delivered by the Servicer

                                    - 111 -
<PAGE>

under this Agreement that any Recoveries have been collected by the Servicer
with respect to the Group I-IV Mortgage Loans, the amount of such Recoveries
will be applied to increase the Certificate Principal Balance of each Class of
Senior-Subordinate Certificates to which Realized Losses have been allocated
(including any such Class of Senior-Subordinate Certificates for which the
Certificate Principal Balance has been reduced to zero), up to the amount of
related Recoveries for such Distribution Date, as follows: (a) first, the
Certificate Principal Balance of each Class of Senior Certificates (other than
the Class IV-X Certificates) related to the Loan Group from which each Recovery
was collected will be increased, pro rata, up to the amount of Realized Losses
previously allocated to reduce the Certificate Principal Balance of each such
Class of Certificates, and (b) second, the Certificate Principal Balance of each
Class of Group C-B Certificates will be increased, in order of seniority, up to
the amount of Realized Losses previously allocated to reduce the Certificate
Principal Balance of each such Class of Certificates. Holders of such
Certificates will not be entitled to any payment in respect of Accrued
Certificate 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
Certificate of such Class in accordance with its respective Percentage Interest.

                  (g) All Realized Losses on the Group I-IV Mortgage Loans shall
be allocated on each Distribution Date to the following REMIC I Regular
Interests in the specified percentages, as follows: 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-ZZ.

                  All Realized Losses on the Group I-IV Mortgage Loans shall be
allocated on each Distribution Date to REMIC III Regular Interest LTIII-IA,
REMIC III Regular Interest LTIII-IIA, REMIC III Regular Interest LTIII-IIIA,
REMIC III Regular Interest LTIII-IVA, REMIC III Regular Interest LTIII-CB1,
REMIC III Regular Interest LTIII-CB2, REMIC III Regular Interest LTIII-CB3,
REMIC III Regular Interest LTIII-CB4, REMIC III Regular Interest LTIII-CB5 and
REMIC III Regular Interest LTIII-CB6, in the same manner and priority as
Realized Losses are allocated to the Corresponding Certificates.

         Section 5.06 DISTRIBUTIONS ON THE GROUP V CERTIFICATES.

         On each Distribution Date, the Trustee shall withdraw funds on deposit
in the related Distribution Account and make distributions to the Group V

                  Distribution Date, applied in accordance with the last
                  paragraph of this clause (i);

                  Remittance Amount for Loan Group VA, to the Class V-M-2
                  Certificates, Current Interest and Carryforward Interest for
                  such Class and Distribution Date;

                           (4) first, from the Group V Interest Remittance
                  Amount for Loan Group VB and then from the Group V Interest
                  Remittance Amount for Loan Group VA, to the Class V-M-1
                  Certificates, Current Interest and Carryforward Interest for
                  such Class and Distribution Date; and

                           (5) for application as part of Monthly Excess
                  Cashflow for such Distribution Date, any Monthly Excess
                  Interest for such Distribution Date.

                  The Group V Interest Remittance Amount for Loan Group VA and
         Loan Group VB distributed pursuant to clause (i)(1) above will be
         applied to the Group V Senior Certificates as follows: (i) amounts
         distributed to the Class V-A-1 Certificates will reduce the Group V

         the Group V Interest Remittance Amount for Loan Group VB in respect of
         such distribution; and (ii) amounts distributed to the Class V-A-2,
         Class V-A-3, Class V-A-4 and Class V-A-5 Certificates will reduce the
         Group V Interest Remittance Amount for Loan Group VB before any
         reduction to the Group V Interest Remittance Amount for Loan Group VA
         in respect of such distribution.

                  (ii) The Principal Payment Amount will be paid on each
         Distribution Date as follows:

                           I. On each Distribution Date (a) prior to the
                  Stepdown Date or (b) with respect to which a Trigger Event is
                  in effect, the Principal Payment Amount will be paid in the

         Section 5.07 ALLOCATION OF REALIZED LOSSES WITH RESPECT TO THE GROUP V
                      MORTGAGE LOANS.

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

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

                  (c) The principal portion of all Realized Losses on the Group
V Mortgage Loans shall be allocated on each Distribution Date as follows: first,
to Net Monthly Excess Cashflow; second, to the Class V-X Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; third, to the
Class V-M-3 Certificates, until the Certificate Principal Balance thereof has
been reduced to zero; fourth, to the Class V-M-2 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; and fifth, to
the Class V-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 Classes of Group V Subordinate
Certificates (other than the Class V-X 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 of Group V Subordinate Certificates (other than the Class V-X
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 Mezzanine 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 V-X Certificates shall be made by reducing the
amount otherwise payable in respect thereof pursuant to Section 5.06(iii)(10).
No allocations of any Realized Losses shall be made to the Certificate Principal
Balances of the Group V Senior Certificates or Class P-V 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 Group V Mortgage Loans,
the amount of such Subsequent Recoveries will be applied to increase the
Certificate Principal Balance of the Class of Mezzanine Certificates with the
highest payment priority to which Realized Losses have been allocated, but not
by more than the amount of Realized Losses previously allocated to that Class of
Mezzanine Certificates

                                    - 119 -
<PAGE>

pursuant to this Section 5.07. The amount of any remaining Subsequent Recoveries
will be applied to sequentially increase the Certificate Principal Balance of
the Mezzanine Certificates, beginning with the Class of Mezzanine 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. 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
Mezzanine Certificate of such Class in accordance with its respective Percentage
Interest.

                  (e) All Realized Losses on the Group V Mortgage Loans shall be
allocated on each Distribution Date to the following REMIC II Regular Interests,
to REMIC II Regular Interest LTII-VA and REMIC II Regular Interest LTII-VB, pro
rata, until the Uncertificated Principal Balance of such REMIC II Regular
Interest has been reduced to zero.

                  (f) The Marker Allocation Percentage of 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 REMIC III Regular
Interest LTIII-IO, second, to Uncertificated Accrued Interest payable to the
REMIC III Regular Interest LTIII-VAA and REMIC III Regular Interest LTIII-VZZ up
to an aggregate amount equal to the REMIC III Interest Loss Allocation Amount,
98% and 2%, respectively; third, to the Uncertificated Principal Balances of the
REMIC III Regular Interest LTIII-VAA and REMIC III Regular Interest LTIII-VZZ up
to an aggregate amount equal to the REMIC III Principal Loss Allocation Amount,
98% and 2%, respectively; fourth, to the Uncertificated Principal Balances of
REMIC III Regular Interest LTIII-VAA, REMIC III Regular Interest LTIII-VM3 and
REMIC III Regular Interest LTIII-ZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC III Regular Interest LTIII-VM3 has
been reduced to zero; fifth, to the Uncertificated Principal Balances of REMIC
III Regular Interest LTIII-VAA, REMIC III Regular Interest LTIII-VM2 and REMIC
III Regular Interest LTIII-VZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC III Regular Interest LTIII-VM2 has
been reduced to zero; and sixth, to the Uncertificated Principal Balances of
REMIC III Regular Interest LTIII-VAA, REMIC III Regular Interest LTIII-VM1 and
REMIC III Regular Interest LTIII-VZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC III Regular Interest LTIII-VM1 has
been reduced to zero.

                  The REMIC III Sub WAC Allocation Percentage of all Realized
Losses on the Group V 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 III 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 III Regular Interest
ending with the designation "SUB," so that the Uncertificated Balance of each
such REMIC III 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 Group V 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 III Regular Interests such that
the

                                    - 120 -

REMIC III Subordinated Balance Ratio is maintained); and third, any remaining
Realized Losses shall be allocated to REMIC III Regular Interest LTIII-VXX.

respect of REMIC III Regular Interest LTIII-VZZ shall be reduced and deferred
when the REMIC III Overcollateralization Amount is less than the REMIC III

                           (ii) second, to the Holders of REMIC III Group V

REMIC III Regular Interest LTIII-PV, until the Uncertificated Principal Balance
of such REMIC III Regular Interest is reduced to zero, provided, however, that
the Uncertificated Principal Balance of REMIC III Regular Interest LTIII-PV
shall not be reduced until the Distribution Date in May 2009 or any Distribution
Date thereafter, at which point such amount shall be distributed to REMIC III
Regular Interest LTIII-PV, until $100 has been distributed pursuant to this

         (iv) to the Holders of REMIC III Regular Interests, in an amount equal
to the remainder of the REMIC III Sub WAC Allocation Percentage of the Group V
Interest Remittance Amount and the Principal Payment Amount for such
Distribution Date after the distributions made pursuant to clause (ii) above,
such that distributions of principal shall be deemed to be made to the REMIC III
Regular Interests first, so as to keep the Uncertificated Principal Balance of
each REMIC III 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 III Regular Interest ending with the
designation "SUB," so that the Uncertificated Principal Balance of each such
REMIC III 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 Group V Senior Certificates
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 principal shall
be distributed to such REMIC III Regular Interests such that the REMIC III
Subordinated Balance Ratio is maintained); and third, any remaining principal to
REMIC III Regular Interest LTIII-VXX.

         Section 5.12 CLASS P CERTIFICATE ACCOUNT AND CLASS P-V CERTIFICATE
                      ACCOUNT.

                  (a) The Trustee shall establish and maintain with itself a
separate, segregated trust account titled "Nomura Asset Acceptance Corporation,
Alternative Loan Trust 2004-AR1 Class P Certificate Account". On the Closing
Date, the Depositor will deposit, or cause to be deposited in the Class P
Certificate Account $100.00. The amount on deposit in the Class P Certificate
Account shall be held uninvested. On the May 2009 Distribution Date, the Trustee
shall withdraw the amount on deposit in the Class P Certificate Account and
remit such amount to the Holders of the Class P Certificates, in reduction of
the Certificate Principal Balance thereof.

                  (b) The Trustee shall establish and maintain with itself a
separate, segregated trust account titled "Nomura Asset Acceptance Corporation,
Alternative Loan Trust 2004-AR1 Class P-V Certificate Account". On the Closing
Date, the Depositor will deposit, or cause to be deposited in the Class P-V
Certificate Account $100.00. The amount on deposit in the Class P-V Certificate
Account shall be held uninvested. On the May 2009 Distribution Date, the Trustee
shall withdraw the amount on deposit in the Class P-V Certificate Account and
remit such amount to the Holders of the Class P-V Certificates, in reduction of
the Certificate Principal Balance thereof.

         Section 5.13 BASIS RISK RESERVE FUND.

                  (a) The Trustee shall establish a Basis Risk Reserve Fund on
behalf of the holders of the Group V Certificates (other than the Class V-X,
Class P-V and Class R-II Certificates). The Basic Risk Reserve Fund must be an
Eligible Account. The Basis Risk Reserve Fund shall be entitled "Basis Risk
Reserve Fund, JPMorgan Chase Bank as Trustee for the benefit of holders of
Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series
2004-AR1, Class V-A-1, Class V-A-2, Class V-A-3, Class V-A-4, Class V-A-5, Class
V-M-1, Class V-M-2 and Class V-M-3". On the Closing Date, the Depositor will
deposit, or cause to be deposited, into the Basis Risk Reserve Fund $5,000. On
each Distribution Date as to which there is a Basis Risk Shortfall payable to
any Class of Certificates, the Trustee

                                    - 128 -
<PAGE>

shall deposit the amounts pursuant to paragraphs 5, 6, 7 and 8 of Section
5.06(iii) into the Basis Risk Reserve Fund and the Trustee has been directed by
the Class V-X Certificateholder to distribute such amounts to the Holders of the
Group V Certificates (other than the Class V-X, Class P-V and Class R-II
Certificates) in the amounts and priorities set forth in Section 5.06(iii).

                  (b) The Basis Risk 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 Reserve Fund. The Class V-X
Certificateholders (other than Holders of the Class V-X, Class P-V and Class
R-II Certificates) shall be the beneficial owners of the Basis Risk Reserve
Fund, subject to the power of the Trustee to transfer amounts under Section
5.06(iii). Amounts in the Basis Risk 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 V-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 V-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 Reserve Fund shall be taxable to the Majority Class
V-X Certificateholder. Any losses on such investments shall be deposited in the
Basis Risk Reserve Fund by the Majority Class V-X Certificateholder out of its
own funds immediately as realized. In the event that the Majority Class V-X
Certificateholder shall fail to provide investment instructions to the Trustee,
the amounts on deposit in the Basis Risk Reserve Fund shall be held uninvested.

                  (c) For federal tax return and information reporting, the
amount allocated to the right of the holders of the Group V Certificates (other
than the Class V-X, Class P-V and Class R-II Certificates) to receive payments
from the Basis Risk Reserve Fund in respect of any Basis Risk Shortfalls that
may be obtained from the Trustee upon written request.

         Section 5.14 LOSS RESERVE ACCOUNT

                  The Trustee shall establish and maintain with itself a
separate, segregated trust account titled "Nomura Asset Acceptance Corporation,
Alternative Loan Trust 2004-AR1 Loss Reserve Account". On the Closing Date, the
Depositor will deposit, or cause to be deposited in the Loss Reserve Account
$100.00. The amount on deposit in the Loss Reserve Account shall be held
uninvested. On each Distribution Date, the amount of any Group II Excess
Interest remaining after payments pursuant to clauses (1) though (4) of Section
5.06(iii) shall be deposited into the Loss Reserve Account. In the event that
the amount of Monthly Excess Interest on any Distribution Date is insufficient
to pay the amounts required to be paid to the Group V Certificates pursuant to
Section 5.06(iii)(1) through (4), the amount (or any portion thereof) on deposit
in the Loss Reserve Account shall be withdrawn and included within the Monthly
Excess Interest and paid to the Group V Certificates in the amount and order of
priority set forth in Section 5.06(iii) (1) through (4). Any amount remaining in
the Loss Reserve Account after the aggregate Certificate Principal Balance of
the Group V Certificates has been reduced to zero will be remitted to the
Depositor.

                  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

         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

                                    - 131 -
<PAGE>

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 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.

                  (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

                                    - 133 -
<PAGE>

         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 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.

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-

                                    - 135 -

entry transfers among the Depository Participants and receive and transmit
distributions of principal and interest on the related Certificates to such
Depository Participants;

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

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

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

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

         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

                                    - 136 -

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

Floor, Dallas, Texas, 75201, Attention: ITS Transfer Department, Nomura Asset
Acceptance Corporation, 2004-AR1 where Certificates may be surrendered for
registration of 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 THE SERVICER

         Section 7.01 LIABILITIES OF THE DEPOSITOR AND THE SERVICER.

herewith only to the extent of the obligations specifically imposed upon and
undertaken by it herein.

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

                  (a) Each of the Depositor and the Servicer 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 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

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.

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

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)

                                    - 139 -

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

this Agreement, unless specifically required to do so pursuant to this
Agreement, the Trustee shall not be required to investigate or make

a result of such course of action by reason of the condition of the Mortgaged

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

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

contained in Section 8.02, (ii) the Trustee shall have consented to such
appointment, (iii) the Rating

                                    - 140 -

Agencies have confirmed in writing that such appointment will not result in a

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

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

                  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

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

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

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 Accounts 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

                                    - 143 -

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 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 Accounts 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.

                                   ARTICLE IX

                    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 related 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

                                    - 146 -
<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 forseeable 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;

                                    - 147 -
<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;

                  (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.

         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 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 Accounts 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 Accounts
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, 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

         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

                                    - 151 -
<PAGE>

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 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 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 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

                                    - 154 -
<PAGE>

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,
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

                                    - 155 -
<PAGE>

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 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.

whatsoever, including reasonable attorney's fees, that may be imposed on,
incurred by or asserted against it or them in any way relating to or arising out
of this Agreement or any action taken or not taken by it or them hereunder
except to the extent caused by the Custodian's negligence or willful misconduct.
If funds in the Trust Fund are insufficient therefor, the Custodian shall
recover such expenses from the Seller. The indemnification provided for under
this Section 9.14 shall survive the termination of this Agreement and the
resignation or removal of the Custodian.

         Section 9.15 RELIANCE OF CUSTODIAN.

                  (a) The Custodian may conclusively rely, as to the truth of

related Certificateholders may surrender their Certificates for payment of the
final distribution and cancellation, shall be given promptly by the Trustee by
letter to the related Certificateholders mailed not earlier than the 10th day
and no later than the 15th day of the month immediately preceding the month of

related Certificates. Upon such final deposit and the receipt by the Trustee of
a Request for Release therefor, the Trustee shall promptly release to the
Depositor, 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

                                    - 160 -

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 relating to the Group I-IV
Mortgage Loans or Group V Mortgage Loans, as applicable, 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 Depositor of the
last Cleanup Call exercisable by the Depositor 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 Depositor, 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 Depositor 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 pursuant to Treasury Regulation Section
1.860F-1. The Depositor shall satisfy all the requirements of a qualified
liquidation under Section 860F of the Code and any regulations thereunder, as
evidenced by an Opinion of Counsel obtained at the expense of the Depositor;

                  (2) During such 90-day liquidation period, and at or prior to
the time of making the final payment on the Certificates, the Depositor shall
sell all of the assets of REMIC I, REMIC II, REMIC III or REMIC IV, as
applicable, 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 (other than cash retained to meet claims), and REMIC I or REMIC II, as
applicable, shall terminate at that time.

                  (b) By their acceptance of the Certificates, the Holders
thereof hereby authorize the Depositor 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
Depositor, 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 Depositor.

                            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 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, 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

                                    - 162 -
<PAGE>

case shall 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:

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

                  (iii) The resignation or termination of the 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

         5.09;

                  (ii) Each annual statement as to compliance described in

the remaining covenants, agreements, provisions or terms of this Agreement and
shall in no way affect the validity or enforceability of the other provisions of
this Agreement or of the Certificates or the rights of the Holders thereof.

         Section 11.07 ASSIGNMENT.

                  Notwithstanding anything to the contrary contained herein,
except as 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.

                  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

                                    - 165 -
<PAGE>

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 equity.

         Section 11.09 CERTIFICATES NONASSESSABLE AND FULLY PAID.

shall not be personally liable for obligations of the Trust Fund, that the

                        MORTGAGE PASS-THROUGH CERTIFICATE
                                 SERIES 2004-AP2

         evidencing a fractional undivided interest in the distributions
         allocable to the Class A-[1][2][3A][3B][4][5][6] 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 servicer, and JPMorgan Chase Bank, 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 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 0.20% per annum.][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 set forth
above]. 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][ Business
Day immediately preceding such Distribution Date], an amount equal to the
product of

                                      -2-
<PAGE>

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.

                  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.

<PAGE>

                  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
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 or after the Distribution Date in June 2006 if on
such Distribution Date the aggregate Stated Principal Balance of the Mortgage
Loans is less than the percentage of the aggregate Stated Principal Balance
specified in the Agreement 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 expiration of 21 years after the death of certain persons identified in the
Agreement.

                  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 payable solely from the assets of the

Acceptance Corporation ("NAAC") or the Trustee or any of their affiliates or any

                  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
Pass-Through Rate set forth above. 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

                        MORTGAGE PASS-THROUGH CERTIFICATE
                                 SERIES 2004-AP2

         evidencing a fractional undivided interest in the distributions
         allocable to the Class 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

                                      -2-
<PAGE>

specified above (the "Agreement"), among NAAC, as depositor (the "Depositor"),
the Seller, as seller, GMAC Mortgage Corporation, as servicer, and JPMorgan
Chase Bank, 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 Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate set forth above. 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 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

                                      -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.

                  Each beneficial owner of a 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, 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, Fitch Ratings 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.

                  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

                                      -4-
<PAGE>

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 on or after the Distribution
Date in June 2006 if on such Distribution Date the aggregate Stated Principal
Balance of the Mortgage Loans is less than the percentage of the aggregate
Stated Principal Balance specified in the Agreement 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 expiration of 21 years after the death of certain persons
identified in the Agreement.

                  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 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 servicer, and
JPMorgan Chase Bank, 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 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

                                      -3-

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 Class C Certificate will be made unless
the Trustee has received either (i) an opinion of counsel acceptable to and in
form and substance satisfactory to the Trustee with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
and holding of a Class C Certificate is permissible under applicable law, will
not constitute or result in a non-exempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Code and will not subject the Trustee, the
Depositor or the Servicer to any obligation or liability in addition to those
undertaken in the Agreement, all in accordance with Section 6.02(b) of the
Agreement or (ii) a representation letter, in the form as described by the
Agreement, stating that the transferee is not an employee benefit or other plan
subject to the prohibited transaction provisions of ERISA or Section 4975 of the
Code (a "Plan"), or any other person (including an investment manager, a named
fiduciary or a trustee of any Plan) acting, directly or indirectly, on behalf of
or purchasing any Certificate with "plan assets" of any Plan.

                  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 of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other

                                      -5-

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 or after the Distribution Date in June 2006 if on
such Distribution Date the aggregate Stated Principal Balance of the Mortgage
Loans is less than the 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 expiration of 21 years after the
death of certain persons identified in the Agreement.

                  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.

to any obligation or liability in addition to those undertaken in the Agreement,
all in accordance with Section 6.02(b) of the Agreement or (ii) a representation
letter, in the form as described by the Agreement, stating that the transferee

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.

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 on or after the Distribution Date in June 2006 if on
such Distribution Date the aggregate Stated Principal Balance of the Mortgage
Loans is less than 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 expiration of 21 years after the
death of certain persons identified in the Agreement.

                  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 2004-AP2

         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
         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,

                                      -3-
<PAGE>

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, 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.

                                      -4-
<PAGE>

                  No transfer of this Class R Certificate will be made unless
the Trustee has received either (i) an opinion of counsel acceptable to and in
form and substance satisfactory to the Trustee with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
and holding of a Class R Certificate is permissible under applicable law, will
not constitute or result in a non-exempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Code and will not subject the Trustee, the
Depositor or the Servicer to any obligation or liability in addition to those
undertaken in the Agreement, all in accordance with Section 6.02(b) of the
Agreement or (ii) a representation letter, in the form as described by the
Agreement, stating that the transferee is not an employee benefit or other plan
subject to the prohibited transaction provisions of ERISA or Section 4975 of the
Code (a "Plan"), or any other person (including an investment manager, a named
fiduciary or a trustee of any Plan) acting, directly or indirectly, on behalf of
or purchasing any Certificate with "plan assets" of any Plan.

                  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,

                                      -5-
<PAGE>

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
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 or after the Distribution Date in June 2006 if on
such Distribution Date the aggregate Stated Principal Balance of the Mortgage
Loans is less than 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 expiration of 21 years after the
death of certain persons identified in the Agreement.

                  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.

                           concerning the Certificates, the Mortgage Loans and

                           from the Depositor or the Seller and is relevant to
                           the Purchaser's decision to purchase the

                  5.       The Purchaser has not and will not nor has it

                           offer, pledge, sell, dispose of or otherwise transfer
                           any Certificate, any interest in any Certificate or
                           any other similar security to any person in any
                           manner, (b) solicit any offer to buy or to accept a

                           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
                           compliance with the provisions of the Pooling and
                           Servicing Agreement.

                  -----------------------

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

                  (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
                           Servicing Agreement (as defined below) a letter to
                           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 (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

                        FORM OF SERVICER'S CERTIFICATION

         Re:      Pooling and Servicing Agreement (the "Pooling and Servicing
                  Agreement"), dated as of June 1, 2004, by and among Nomura
                  Asset Acceptance Corporation, as depositor (the "Depositor"),
                  Nomura Credit & Capital, Inc., as seller (the "Seller"),
                  JPMorgan Chase Bank, as trustee (the "Trustee"), GMAC Mortgage
                  Corporation, as servicer, ("GMAC")

I, [identify the certifying individual], certify to the Depositor and the
Trustee, and their officers, directors and affiliates, and with the knowledge
and intent that they will rely upon this certification, that:

1.       I am responsible for reviewing the activities performed by GMAC under
         the Pooling and Servicing Agreement and based upon my knowledge and the
         annual compliance review required under the Pooling and Servicing
         Agreement, and except as disclosed in the annual compliance statement
         required to be delivered to the Trustee in accordance with the terms of
         the Pooling and Servicing Agreement (which has been so delivered to the
         Trustee), GMAC has fulfilled its obligations under the Pooling and
         Servicing Agreement. Based upon my knowledge, the annual statement of
         compliance delivered by GMAC under the Pooling and Servicing Agreement
         does not contain any untrue statement of material fact or omit to state
         a material fact necessary to make the statements made, in light of the
         circumstances under which such statement was made, not misleading; and

2.       Based on my knowledge, all significant deficiencies relating to GMAC's
         compliance with the minimum servicing standards for purposes of the
         report provided by an independent public accountant, after conducting a
         review conducted in compliance with the Uniform Single Attestation
         Program for Mortgage Bankers or similar procedure, as set forth in the
         Pooling and Servicing Agreement, have been disclosed to such accountant
         and are included in such reports.

                  This Pooling and Servicing Agreement, is dated and effective
as of August 1, 2004, among AMERIQUEST MORTGAGE SECURITIES INC., as Depositor,
AMERIQUEST MORTGAGE COMPANY, as Master Servicer and DEUTSCHE BANK NATIONAL TRUST
COMPANY, as Trustee.

                             PRELIMINARY STATEMENT:

                  The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
each REMIC (as defined herein) created hereunder. The Trust Fund will consist of
a segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement.

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets (other than any Master Servicer Prepayment Charge Payment
Amounts, the Net WAC Rate Carryover Reserve Account and the Cap Contracts)
subject to this Agreement as a REMIC for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC I." The Class R-I
Interest will be the sole class of "residual interests" in REMIC I for purposes
of the REMIC Provisions (as defined herein). The following table irrevocably
sets forth the designation, the REMIC I Remittance Rate, the initial
Uncertificated Balance and, solely for purposes of satisfying Treasury
regulation section 1.860G- 1(a)(4)(iii), the "latest possible maturity date" for
each of the REMIC I Regular Interests (as defined herein). None of the REMIC I
Regular Interests will be certificated.

Certificates, REMIC I Regular Interest I-LTA1, REMIC I Regular Interest I-LTA2,
REMIC I Regular Interest I-LTA3, REMIC I Regular Interest I-LTA4, REMIC I
Regular Interest I-LTA5, REMIC I Regular Interest I- LTM1, REMIC I Regular
Interest I-LTM2, REMIC I Regular Interest I-LTM3, REMIC I Regular Interest
I-LTM4, REMIC I Regular Interest I-LTM5, REMIC I Regular Interest I-LTM6, REMIC
I Regular Interest I-LTM7, REMIC I Regular Interest I-LTM8, REMIC I Regular
Interest I-LTM9 and REMIC I Regular Interest I-LTM10 and any Interest Accrual
Period therefor, the rate determined by the Trustee on the related Interest
Determination Date on the basis of the offered rate for one-month U.S. dollar
deposits, as such rate appears on Telerate Page 3750 as of 11:00 a.m. (London
time) on such Interest Determination Date; provided that if such rate does not
appear on Telerate Page 3750, the rate for such date will be determined on the
basis of the offered rates of the Reference Banks for one-month U.S. dollar
deposits, as of 11:00 a.m. (London time) on such Interest Determination Date. In
such event, the Trustee will request the principal London office of each of the
Reference Banks to provide a quotation of its rate. If on such Interest
Determination Date, two or more Reference Banks provide such offered quotations,
One-Month LIBOR for the related Interest Accrual Period shall be the arithmetic
mean of such offered quotations (rounded upwards, if necessary, to the nearest
whole multiple of 1/16%). If on such Interest Determination Date, fewer than two
Reference Banks provide such offered quotations, One-Month LIBOR for the related
Interest Accrual Period shall be the higher of (i) LIBOR as determined on the
previous Interest Determination Date and (ii) the Reserve Interest Rate.
Notwithstanding the foregoing, if, under the priorities described above, LIBOR
for an Interest Determination Date would be based on LIBOR for the previous
Interest Determination Date for the third consecutive Interest Determination

         to 2.00% of the Pool Balance as of the Cut- off Date;

                  (ii) the original Mortgage, with evidence of recording
         thereon, and a copy, certified by the appropriate recording office, of
         the recorded power of attorney, if the Mortgage was executed pursuant
         to a power of attorney, with evidence of recording thereon;

                  (iii) an original Assignment of the Mortgage assigned in
         blank, without recourse;

                  (iv) the original recorded intervening Assignment or
         Assignments of the Mortgage showing a complete chain of assignment from
         the originator to the Person assigning the Mortgage to the Trustee as
         contemplated by the immediately preceding clause (iii) or the original
         unrecorded intervening Assignments;

                  (v) the original or copies of each assumption, modification,
         written assurance or substitution agreement, if any; and

                  (vi) the original lenders's title insurance policy or an
         attorney's opinion of title or similar guarantee of title acceptable to
         mortgage lenders generally in the jurisdiction where the Mortgaged
         Property is located, together with all endorsements or riders which
         were issued with or subsequent to the issuance of such policy, or in
         the event such original title policy is unavailable, a written
         commitment or uniform binder or preliminary report of title issued by
         the title insurance or escrow company.

                  If any of the documents referred to in Sections 2.01(ii),
(iii) or (iv) above has as of the Closing Date been submitted for recording but
either (x) has not been returned from the applicable public recording office or
(y) has been lost or such public recording office has retained the original of
such document, the obligations of the Depositor to deliver such documents shall
be deemed to be satisfied upon (1) delivery to the Trustee, or to the
appropriate Custodian on behalf of the Trustee, of a copy of each such document
certified by the applicable Originator in the case of (x) above or the
applicable public recording office in the case of (y) above to be a true and
complete copy of the original that was submitted for recording and (2) if such
copy is certified by the applicable Originator, delivery to the Trustee, or to
the appropriate Custodian on behalf of the Trustee, promptly upon receipt
thereof of either the original or a copy of such document certified by the
applicable public recording office to be a true and complete copy of the
original. If the original lender's title insurance policy was not delivered
pursuant to Section 2.01(vi) above, the Depositor shall deliver or cause to be
delivered to the Trustee, or to the appropriate Custodian on behalf of the
Trustee, promptly after receipt thereof, the original lender's title insurance
policy. The Depositor shall deliver or cause to be delivered to the Trustee, or
to the appropriate Custodian on behalf of the Trustee, promptly upon receipt

original documents evidencing an assumption or modification of any Mortgage
Loan.

                  The Master Servicer (in its capacity as Seller) shall promptly
(and in no event later than thirty (30) Business Days, subject to extension upon
a mutual agreement between the Master Servicer and the Trustee, following the
later of (i) the Closing Date, (ii) the date on which the Seller receives the
Assignment from the Custodian and (iii) the date of receipt by the Master
Servicer of the recording information for a Mortgage) submit or cause to be
submitted for recording, at no expense to the Trust Fund or the Trustee, in the
appropriate public office for real property records, each Assignment referred to
in Sections 2.01(iii) and (iv) above and shall execute each original Assignment
referred to in section 2.01(iii) above in the following form: "Deutsche Bank
National Trust Company, as Trustee under the applicable agreement." In the event
that any such Assignment is lost or returned unrecorded because of a defect
therein, the Master Servicer (in its capacity as Seller) shall promptly prepare
or cause to be prepared a substitute Assignment or cure or cause to be cured
such defect, as the case may be, and thereafter cause each such Assignment to be
duly recorded.

                  Notwithstanding the foregoing, however, for administrative
convenience and facilitation of servicing and to reduce closing costs, the
Assignments of Mortgage shall not be required to be submitted for recording
(except with respect to any Mortgage Loan located in Maryland) unless such
failure to record would result in a withdrawal or a downgrading by any Rating
Agency of the rating on any Class of Certificates (in the case of the Insured
Certificates, without regard to the Policy); provided further, however, each
Assignment of Mortgage shall be submitted for recording by the Seller in the
manner described above, at no expense to the Trust Fund or the Trustee, upon the
earliest to occur of: (i) reasonable direction by Holders of Certificates
entitled to at least 25% of the Voting Rights, the Certificate Insurer or the
NIMS Insurer, (ii) failure of the Master Servicer Termination Test, (iii) the
occurrence of a bankruptcy or insolvency relating to the Seller, (iv) the
occurrence of a servicing transfer as described in Section 7.02 hereof and (v)
if the Seller is not the Master Servicer and with respect to any one assignment
or Mortgage, the occurrence of a bankruptcy, insolvency or foreclosure relating
to the Mortgagor under the related Mortgage. Notwithstanding the foregoing, if
the Master Servicer is unable to pay the cost of recording the Assignments of
Mortgage, such expense will be paid by the Trustee and shall be reimbursable to
the Trustee as an Extraordinary Trust Fund Expense.

                  All original documents relating to the Mortgage Loans that are
not delivered to the Trustee, or to the appropriate Custodian on behalf of the
Trustee, are and shall be held by or on behalf of the Seller, the Depositor or
the Master Servicer, as the case may be, in trust for the benefit of the Trustee
on behalf of the Certificateholders and the Certificate Insurer. In the event
that any such original document is required pursuant to the terms of this
Section to be a part of a Mortgage File, such document shall be delivered
promptly to the Trustee, or to the appropriate Custodian on behalf of the
Trustee. Any such original document delivered to or held by the Depositor that
is not required pursuant to the terms of this Section to be a part of a Mortgage
File, shall be delivered promptly to the Master Servicer.

                  The parties hereto understand and agree that it is not
intended that any mortgage loan be included in the Trust that is a "High-Cost
Home Loan" as defined by HOEPA or any other applicable predatory or abusive
lending laws.

                  SECTION 2.02. Acceptance of REMIC I by the Trustee.

                                       59
<PAGE>

                  Subject to the provisions of Section 2.01 and subject to any
exceptions noted on the exception report described in the next paragraph below,
the Trustee acknowledges receipt (or, with respect to Mortgage Loans subject to
a Custodial Agreement, receipt by the respective Custodian as the duly appointed
agent of the Trustee) of the documents referred to in Section 2.01 (other than
such documents described in Section 2.01(v)) above and all interests and all
other assets included in the definition of "REMIC I" under clauses (i), (iii),
(iv) and (v) (to the extent of amounts deposited into the Distribution Account)
and declares that it, or such Custodian as its agent, holds and will hold such
documents and the other documents delivered to it constituting a Mortgage File,
and that it holds or will hold all such assets and such other assets included in
the definition of "REMIC I" in trust for the exclusive use and benefit of all
present and future Certificateholders and the Certificate Insurer.

                  On or prior to the Closing Date, the Trustee agrees, for the
benefit of the Certificateholders and the Certificate Insurer, to execute and
deliver (or cause the Custodian to execute and deliver) to the Depositor, the
Certificate Insurer and the NIMS Insurer an acknowledgment of receipt of the
Mortgage Note (with any exceptions noted), substantially in the form attached as
Exhibit C-3 hereto.

                  The Trustee agrees, for the benefit of the Certificateholders
and the Certificate Insurer, to review (or cause a Custodian on its behalf to
review) each Mortgage Note within 45 days of the Closing Date and to certify in
substantially the form attached hereto as Exhibit C-1 (or cause the Custodian to
certify in the form of the Initial Certification attached to the Custodial
Agreement) that, as to each Mortgage Loan listed in the Mortgage Loan Schedule
(other than any Mortgage Loan paid in full or any Mortgage Loan specifically
identified in the exception report annexed thereto as not being covered by such
certification), (i) all documents constituting part of such Mortgage File (other
than such documents described in Section 2.01(v)) required to be delivered to it
pursuant to this Agreement are in its possession, (ii) such documents have been
reviewed by it or such Custodian and are not mutilated, torn or defaced unless
initialed by the related borrower and relate to such Mortgage Loan, (iii) based
on its or the Custodian's examination and only as to the foregoing, the
information set forth in the Mortgage Loan Schedule that corresponds to items
(1) through (3), (6), (9), (10), (13), (15) and (19) of the definition of
"Mortgage Loan Schedule" accurately reflects information set forth in the
Mortgage File. It is herein acknowledged that, in conducting such review, the
Trustee or such Custodian was under no duty or obligation (i) to inspect, review
or examine any such documents, instruments, certificates or other papers to
determine whether they are genuine, enforceable, or appropriate for the
represented purpose or whether they have actually been recorded or that they are
other than what they purport to be on their face or (ii) to determine whether
any Mortgage File should include any of the documents specified in clause (v) of
Section 2.01.

                  Prior to the first anniversary date of this Agreement the
Trustee shall deliver to the Depositor, the Master Servicer, the Certificate
Insurer and the NIMS Insurer a final certification in the form annexed hereto as
Exhibit C-2 (or shall cause the Custodian to deliver to the Trustee, the
Depositor, the Master Servicer, the Certificate Insurer and the NIMS Insurer a
final certification in the form attached to the Custodial Agreement) evidencing
the completeness of the Mortgage Files, with any applicable exceptions noted
thereon, with respect to all of the Mortgage Loans. Upon the request of the
Master Servicer or the Certificate Insurer, any exception report related to the
final

                                       60
<PAGE>

certification shall be provided in an electronic computer readable format as
mutually agreed upon by the Master Servicer and the Trustee.

                  If in the process of reviewing the Mortgage Files and making
or preparing, as the case may be, the certifications referred to above, the
Trustee or any Custodian finds any document or documents constituting a part of
a Mortgage File to be missing, mutilated, torn or defaced or does not conform to
the requirements identified above, at the conclusion of its review the Trustee
(or a Custodian on behalf of the Trustee) shall so notify the Depositor, the
NIMS Insurer, the Certificate Insurer and the Master Servicer. In addition, upon
the discovery by the Depositor, the NIMS Insurer, the Master Servicer, the
Certificate Insurer or the Trustee of a breach of any of the representations and
warranties made by the Seller in the Mortgage Loan Purchase Agreement in respect
of any Mortgage Loan which materially adversely affects such Mortgage Loan or
the interests of the related Certificateholders or the Certificate Insurer in
such Mortgage Loan, the party discovering such breach shall give prompt written
notice to the other parties and the Certificate Insurer.

                  The Trustee (or a Custodian on behalf of the Trustee) shall,
at the written request and expense of any Certificateholder, Certificate Owner
or the Certificate Insurer, provide a written report to such Certificateholder,
Certificate Owner or the Certificate Insurer, of all Mortgage Files released to
the Master Servicer for servicing purposes.

                  SECTION 2.03. Repurchase or Substitution of Mortgage Loans by
                                the Seller or the Depositor; Payment of
                                Prepayment Charge Payment Amounts.

                  (a) Upon discovery or receipt of notice (including notice
under Section 2.02) of any materially defective document in, or that a document
is missing from, the Mortgage File or of the breach by the Seller of any
representation, warranty or covenant under the Mortgage Loan Purchase Agreement
in respect of any Mortgage Loan which materially adversely affects the value of
such Mortgage Loan or the interest therein of the Certificateholders or the
Certificate Insurer, the Trustee shall promptly notify the Seller, the NIMS
Insurer, the Certificate Insurer and the Master Servicer of such defect, missing
document or breach and request that the Seller deliver such missing document or
cure such defect or breach within 90 days from the date the Seller had knowledge
or was notified of such missing document, defect or breach, and if the Seller
does not deliver such missing document or cure such defect or breach in all
material respects during such period, the Master Servicer (or, in accordance
with Section 6.06(b), the Trustee) shall enforce the obligations of the Seller
under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from
REMIC I at the Purchase Price within 90 days after the date on which the Seller
was notified (subject to Section 2.03(d)) of such missing document, defect or
breach, if and to the extent that the Seller is obligated to do so under the
Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased
Mortgage Loan shall be deposited in the Collection Account, and the Trustee,
upon receipt of written certification from the Master Servicer of such deposit,
shall release to the Seller the related Mortgage File and shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, as the Seller shall furnish to it and as shall be necessary to vest in
the Seller any Mortgage Loan released pursuant hereto, and the Trustee shall not
have any further responsibility with regard to such Mortgage File. In lieu of
repurchasing any such Mortgage Loan as provided above, if so provided in the
Mortgage Loan Purchase Agreement, the Seller may cause

                                       61
<PAGE>

such Mortgage Loan to be removed from REMIC I (in which case it shall become a
Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage
Loans in the manner and subject to the limitations set forth in Section 2.03(c).
It is understood and agreed that the obligation of the Seller to cure or to
repurchase (or to substitute for) any Mortgage Loan as to which a document is
missing, a material defect in a document exists or as to which such a breach has
occurred and is continuing shall constitute the sole remedy respecting such
omission, defect or breach available to the Trustee on behalf of the
Certificateholders.

                  (b)(i) Promptly upon the earlier of discovery by the Master
         Servicer or receipt of notice by the Master Servicer of the breach of
         any representation, warranty or covenant of the Master Servicer set
         forth in Section 2.05, which materially and adversely affects the
         interests of the Certificateholders in any Mortgage Loan, the Master
         Servicer shall cure such breach in all material respects.

                  (ii) Notwithstanding the provisions of Section 2.03(b)(i)
         above,

                  (A) on the later of (x) the Master Servicer Remittance Date
         next following the earlier of discovery by the Master Servicer or
         receipt of notice by the Master Servicer of the breach of the
         representation made by the Master Servicer in Section 2.05(vii), which
         breach materially and adversely affects the interests of the Holders of
         the Class P Certificates to any Prepayment Charge and (y) the Master
         Servicer Remittance Date next following the Prepayment Period relating
         to such a breach, the Master Servicer shall deposit into the Collection
         Account the amount of the scheduled Prepayment Charge, less any amount
         collected and deposited by the Master Servicer into the Collection
         Account in respect of such Prepayment Charge; and

                  (B) on the later of (x) the Master Servicer Remittance Date
         next following the earlier of discovery by the Master Servicer or
         receipt of notice by the Master Servicer of the breach of the covenant
         made by the Master Servicer in Section 2.05(viii), which breach
         materially and adversely affects the interests of the Holders of the
         Class P Certificates to any Prepayment Charge and (y) the Master
         Servicer Remittance Date next following the Prepayment Period relating
         to such a breach, the Master Servicer shall deposit into the Collection
         Account, as a Master Servicer Prepayment Charge Payment Amount, the
         amount of the waived Prepayment Charge, but only to the extent required
         under Section 2.03(b)(iii) below.

                  (iii) If with respect to any Prepayment Period,

                  (A) the dollar amount of Prepayment Charges that are the
         subject of breaches by the Master Servicer of the covenant made by the
         Master Servicer in Section 2.05(viii), which breaches materially and
         adversely affect the interests of the Holders of the Class P
         Certificates to such Prepayment Charges, exceeds

                  (B) 5% of the total dollar amount of Prepayment Charges
         payable by Mortgagors in connection with Principal Prepayments on the
         related Mortgage Loans that occurred during such Prepayment Period,

                                       62
<PAGE>

then the amount required to be paid by the Master Servicer pursuant to Section
2.03(b)(ii)(B) above shall be limited to an amount, that when added to the
amount of Prepayment Charges actually collected by the Master Servicer in
respect of Prepayment Charges relating to Principal Prepayments on the related
Mortgage Loans that occurred during such Prepayment Period, will yield a sum
equal to 95% of the total dollar amount of Prepayment Charges (exclusive of (A)
Prepayment Charges not enforced or collected upon because (i) the enforceability
thereof shall have been limited by bankruptcy, insolvency, moratorium,
receivership and other similar laws relating to creditors' rights generally or
(ii) the collectability thereof shall have been limited due to acceleration in
connection with a foreclosure or other involuntary payment and (B) Prepayment
Charges waived by the Master Servicer when such waiver does not breach the
covenant set forth in Section 2.05(viii)) payable by Mortgagors in connection
with Principal Prepayments on the related Mortgage Loans that occurred during
such Prepayment Period.

                  (c) Any substitution of Qualified Substitute Mortgage Loans
for Deleted Mortgage Loans made pursuant to Section 2.03(a), in the case of the
Seller, or Section 2.03(b), in the case of the Depositor, must be effected prior
to the date which is two years after the Startup Day for REMIC I.

                  As to any Deleted Mortgage Loan for which the Seller or the
Depositor substitutes a Qualified Substitute Mortgage Loan or Loans, such
substitution shall be effected by the Seller or the Depositor, as the case may
be, delivering to the Trustee (or a Custodian on behalf of the Trustee), for
such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the
Mortgage, the Assignment to the Trustee, and such other documents and
agreements, with all necessary endorsements thereon, as are required by Section
2.01, together with an Officers' Certificate providing that each such Qualified
Substitute Mortgage Loan satisfies the definition thereof and specifying the
Substitution Shortfall Amount (as described below), if any, in connection with
such substitution. The Trustee (or a Custodian on behalf of the Trustee) shall
acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and,
within ten Business Days thereafter, review such documents as specified in
Section 2.02 and deliver to the Depositor, the NIMS Insurer, the Certificate
Insurer, the Trustee and the Master Servicer, with respect to such Qualified
Substitute Mortgage Loan or Loans, a certification substantially in the form
attached hereto as Exhibit C-1, with any applicable exceptions noted thereon.
Within one year of the date of substitution, the Trustee shall deliver to the
Depositor, the NIMS Insurer, the Certificate Insurer and the Master Servicer a
certification substantially in the form of Exhibit C-2 hereto with respect to
such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions
noted thereon. Monthly Payments due with respect to Qualified Substitute
Mortgage Loans in the month of substitution are not part of REMIC I and will be
retained by the Depositor or the Seller, as the case may be. For the month of
substitution, distributions to Certificateholders will reflect the Monthly
Payment due on such Deleted Mortgage Loan on or before the Due Date in the month
of substitution, and the Depositor or the Seller, as the case may be, shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Deleted Mortgage Loan. The Depositor shall give or cause to be given
written notice to the Certificateholders, the NIMS Insurer and the Certificate
Insurer that such substitution has taken place, shall amend the Mortgage Loan
Schedule and, if applicable, the Prepayment Charge Schedule, to reflect the
removal of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Qualified Substitute Mortgage Loan or Loans and shall
deliver a copy of such amended Mortgage Loan Schedule to the Trustee, the
Certificate Insurer and the NIMS Insurer.

                                       63
<PAGE>

Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall
constitute part of the Mortgage Pool and shall be subject in all respects to the
terms of this Agreement and, in the case of a substitution effected by the
Seller, the Mortgage Loan Purchase Agreement, including all applicable
representations and warranties thereof.

                  For any month in which the Depositor or the Seller substitutes
one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage
Loans, the Master Servicer will determine the amount (the "Substitution
Shortfall Amount"), if any, by which the aggregate Purchase Price of all such
Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified
Substitute Mortgage Loan, the Scheduled Principal Balance thereof as of the date
of substitution, together with one month's interest on such Scheduled Principal
Balance at the applicable Net Mortgage Rate. On the date of such substitution,
the Depositor or the Seller, as the case may be, will deliver or cause to be
delivered to the Master Servicer for deposit in the Collection Account an amount
equal to the Substitution Shortfall Amount, if any, and the Trustee, upon
receipt of the related Qualified Substitute Mortgage Loan or Loans and
certification by the Master Servicer of such deposit, shall release to the
Depositor or the Seller, as the case may be, the related Mortgage File or Files
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as the Depositor or the Seller, as the case may be, shall
deliver to it and as shall be necessary to vest therein any Deleted Mortgage
Loan released pursuant hereto.

                  In addition, the Depositor or the Seller, as the case may be,
shall obtain at its own expense and deliver to the Trustee, the NIMS Insurer and
the Certificate Insurer an Opinion of Counsel to the effect that such
substitution will not cause (a) any federal tax to be imposed on any Trust
REMIC, including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup date" under Section 860G(d)(1) of the Code, or (b) any Trust REMIC
to fail to qualify as a REMIC at any time that any Certificate is outstanding.

                  (d) Upon discovery by the Depositor, the NIMS Insurer, the
Certificate Insurer, the Seller, the Master Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code, the party discovering such fact shall within two
Business Days give written notice thereof to the other parties. In connection
therewith, the Seller or the Depositor shall repurchase or, subject to the
limitations set forth in Section 2.03(c), substitute one or more Qualified
Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the
earlier of discovery or receipt of such notice with respect to such affected
Mortgage Loan. Such repurchase or substitution shall be made by the Seller. Any
such repurchase or substitution shall be made in the same manner as set forth in
Section 2.03(a). The Trustee shall reconvey to the Depositor or the Seller, as
the case may be, 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.

                  SECTION 2.04. [Reserved].

                  SECTION 2.05. Representations, Warranties and Covenants of the
                                Master Servicer.

                  The Master Servicer hereby represents, warrants and covenants
to the Trustee, for the benefit of each of the Trustee, the Certificateholders
and to the Depositor that as of the Closing Date or as of such date specifically
provided herein:

                  (i) The Master Servicer is a corporation duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware and is duly authorized and qualified to transact any and all
         business contemplated by this Agreement to be conducted by the Master
         Servicer in any state in which a Mortgaged Property is located or is
         otherwise not required under applicable law to effect such
         qualification and, in any event, is in compliance with the doing
         business laws of any such State, to the extent necessary to ensure its
         ability to enforce each Mortgage Loan and to service the Mortgage Loans
         in accordance with the terms of this Agreement;

                  (ii) The Master Servicer has the full corporate power and
         authority to service each Mortgage Loan, and to execute, deliver and
         perform, and to enter into and consummate the transactions contemplated
         by this Agreement and has duly authorized by all necessary corporate
         action on the part of the Master Servicer the execution, delivery and
         performance of this Agreement; and this Agreement, assuming the due

         Trustee, constitutes a legal, valid and binding obligation of the
         Master Servicer, enforceable against the Master Servicer in accordance
         with its terms, except to the extent that (a) the enforceability
         thereof may be limited by bankruptcy, insolvency, moratorium,
         receivership and other similar laws relating to creditors' rights
         generally and (b) the remedy of specific performance and injunctive and
         other forms of equitable relief may be subject to the equitable
         defenses and to the discretion of the court before which any proceeding
         therefor may be brought;

                  (iii) The execution and delivery of this Agreement by the
         Master Servicer, the servicing of the Mortgage Loans by the Master
         Servicer hereunder, the consummation of any other of the transactions
         herein contemplated, and the fulfillment of or compliance with the
         terms hereof are in the ordinary course of business of the Master
         Servicer and will not (A) result in a breach of any term or provision
         of the charter or by-laws of the Master Servicer or (B) conflict with,
         result in a breach, violation or acceleration of, or result in a
         default under, the terms of any other material agreement or instrument

         ability of the Master Servicer to perform its obligations under this
         Agreement

         or (y) the business, operations, financial condition, properties or
         assets of the Master Servicer taken as a whole;

                  (iv) The Master Servicer is an approved seller/servicer for
         Fannie Mae or Freddie Mac in good standing and is a HUD approved

                  (v) Except as disclosed in the Prospectus Supplement, no
         litigation is pending against the Master Servicer that would materially
         and adversely affect the execution, delivery or enforceability of this
         Agreement or the ability of the Master Servicer to service the Mortgage
         Loans or to perform any of its other obligations hereunder in
         accordance with the terms hereof;

                  (vi) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the execution, delivery
         and performance by the Master Servicer of, or compliance by the Master
         Servicer with, this Agreement or the consummation of the transactions
         contemplated by this Agreement, except for such consents, approvals,

         Closing Date;

                  (vii) The information set forth in the Prepayment Charge

         furnished and each Prepayment Charge is permissible and enforceable in
         accordance with its terms (except to the extent that (i) the
         enforceability thereof may be limited by bankruptcy, insolvency,
         moratorium, receivership and other similar laws relating to creditors'
         rights generally and (ii) the collectability thereof may be limited due
         to acceleration in connection with a foreclosure or other involuntary

                  (viii) The Master Servicer will not waive any Prepayment

         to a default or a reasonably foreseeable default, (y) such waiver would
         maximize recovery of total proceeds taking into account the value of
         such Prepayment Charge and related Mortgage Loan and (z) doing so is

         any waiver of a Prepayment Charge in connection with a refinancing of a

         related to a default or a reasonably foreseeable default;

                  (ix) The information set forth in the "monthly tape" provided
         to the Trustee or any of its affiliates is true and correct in all

<PAGE>

                  (x) With respect to each Mortgage Loan, the Assignment is in
         recordable form; (except that the name of the assignee and the
         recording information with respect to such Mortgage Loan is blank) and
         each Mortgage Loan was originated in the name of the Master Servicer or
         an affiliate thereof;

                  (xi) The Master Servicer has fully furnished and will continue
         to fully furnish, in accordance with the Fair Credit Reporting Act and
         its implementing regulations, accurate and complete information (e.g.,
         favorable and unfavorable) on its borrower credit files to Equifax,
         Experian and Trans Union Credit Information Company or their successors
         on a monthly basis; and

                  (xii) The Master Servicer shall transmit full-file credit
         reporting data for each Mortgage Loan pursuant to Fannie Mae Guide
         Announcement 95-19 and for each Mortgage Loan, the Master Servicer
         shall report one of the following statuses each month as follows: new
         origination, current, delinquent (30-, 60-, 90-days, etc.), foreclosed,
         or charged-off.

                  It is understood and agreed that the representations,
warranties and covenants set forth in this Section 2.05 shall survive delivery
of the Mortgage Files to the Trustee or to a Custodian, as the case may be, and
shall inure to the benefit of the Trustee, the Depositor and the
Certificateholders. Upon discovery by any of the Depositor, the NIMS Insurer,
the Certificate Insurer, the Master Servicer or the Trustee of a breach of any
of the foregoing representations, warranties and covenants which materially and
adversely affects the value of any Mortgage Loan, Prepayment Charge or the
interests therein of the Certificateholders, the party discovering such breach
shall give prompt written notice (but in no event later than two Business Days
following such discovery) to the NIMS Insurer and the Trustee. Subject to
Section 7.01, the obligation of the Master Servicer set forth in Section 2.03(b)
to cure breaches (or in the case of the representations, warranties and
covenants set forth in Section 2.05(vii) and Section 2.05(viii) above, to
otherwise remedy such breaches pursuant to Section 2.03(b)) shall constitute the
sole remedies against the Master Servicer available to the Certificateholders,
the Depositor or the Trustee on behalf of the Certificateholders respecting a
breach of the representations, warranties and covenants contained in this
Section 2.05. The preceding sentence shall not, however, limit any remedies
available to the Certificateholders, the Depositor or the Trustee on behalf of
the Certificateholders (other than in the case of the representations,
warranties and covenants set forth in Section 2.05(vii) and Section 2.05(viii)
above) pursuant to the Mortgage Loan Purchase Agreement signed by the Master
Servicer in its capacity as Seller, respecting a breach of the representations,
warranties and covenants of the Master Servicer in its capacity as Seller
contained in such Mortgage Loan Purchase Agreement.

                  SECTION 2.06. Issuance of the REMIC I Regular Interests and
                                the Class R-I Interest.

                  The Trustee acknowledges the assignment to it of the Mortgage
Loans and the delivery to it of the 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.
Concurrently with such assignment and delivery and in exchange therefor, the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed, authenticated and delivered to or upon the order
of the Depositor, the Class R-I Interest

                                       67

in authorized denominations. 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 Class R Certificateholders and
REMIC II (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;
                                Acceptance of REMIC II by the Trustee; Issuance
                                of Class R Certificates.

                  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
Certificateholders 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 Class R Certificateholders and REMIC II (as holder of
the REMIC I Regular Interests). The rights of the Class R Certificateholders 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 Certificates and REMIC
II Certificates, respectively, and all ownership interests evidenced or
constituted by the Class R Certificates and the REMIC II Certificates, shall be
as set forth in this Agreement.

                  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
or the Trustee has executed, authenticated and delivered to or upon the order of
the Depositor, the Class R Certificates in authorized denominations. The

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

                  SECTION 3.01. Master Servicer to Act as Master Servicer.

                  The Master Servicer shall service and administer the Mortgage
Loans on behalf of the Trustee and in the best interests of and for the benefit
of the Certificateholders and the Certificate Insurer (as determined by the
Master Servicer in its reasonable judgment) in accordance with (i) the terms of
the respective Mortgage Loans and any insurance policies related thereto, (ii)
all Applicable Regulations, (iii) the terms of this Agreement, (iv) the Loss
Mitigation Action Plan, if applicable, and (v) to the extent consistent with the
preceding requirements, in the same manner in which it services and administers
similar mortgage loans for its own portfolio, giving due consideration to
customary and usual standards of practice of prudent mortgage lenders and loan
servicers administering similar mortgage loans but without regard to:

                  (i) any relationship that the Master Servicer, any
         Sub-Servicer or any Affiliate of the Master Servicer or any
         Sub-Servicer may have with the related Mortgagor;

                  (ii) the ownership of any Certificate by the Master Servicer
         or any Affiliate of the Master Servicer;

                  (iii) the Master Servicer's obligation to make Advances or
         Servicing Advances; or

                  (iv) the Master Servicer's or any Sub-Servicer's right to
         receive compensation for its services hereunder or with respect to any
         particular transaction (the "Servicing Standard").

                  Subject only to the above-described servicing standards and
the terms of this Agreement and of the respective Mortgage Loans, the Master
Servicer shall have full power and authority, acting alone or through
Sub-Servicers as provided in Section 6.06, to do or cause to be done any and all
things in connection with such servicing and administration which it may deem
necessary or desirable. Without limiting the generality of the foregoing, the
Master Servicer in its own name or in the name of a Sub-Servicer is hereby
authorized and empowered by the Trustee, in accordance with the servicing
standards set forth above, (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge, or of forbearance, or
of modification and all other comparable instruments, with respect to the
Mortgage Loans and the Mortgaged Properties, (ii) to institute foreclosure
proceedings or obtain a deed-in-lieu of foreclosure to convert the ownership of
such properties, and to hold or cause to be held title to such properties, in
the name of the Trust Fund, on behalf of the Trustee, the Certificate Insurer
and the Certificateholders, (iii) to market, sell and transfer title of REO
Properties held in the name of the Trust Fund to third party purchasers upon
terms and conditions the Master Servicer deems reasonable under the Servicing
Standard, (iv) to bring or respond to civil actions or complaints (in its own
name or that of the Trust Fund or the Trustee on behalf of the Trust Fund)
related to any Mortgage Loan, Mortgaged Property or REO

                                       69
<PAGE>

Property held by the Trust Fund and (v) execute any other document necessary or
appropriate to enable the Master Servicer to carry out its servicing and
administrative duties hereunder consistent with the Servicing Standard.

                  At the written request of the Master Servicer, the Trustee
shall execute and furnish to the Master Servicer such documents as are necessary
or appropriate to enable the Master Servicer to carry out its servicing and
administrative duties hereunder. By execution of this Agreement, the Trustee, on
behalf of the Trust Fund, hereby grants to the Master Servicer a power of
attorney to execute any and all documents necessary to carry out any and all
servicing duties described in this Agreement (including the taking of and
transferring title of REO Properties to third parties held in the name of the
Trustee for the benefit of the Trust) and expressly confirms that this paragraph
along with the face page and a copy of the signature page (duly executed) to
this Agreement shall constitute the power of attorney for evidentiary and/or
recording purposes. The Trustee shall not be liable for the actions of the
Master Servicer or any Sub-Servicers under such powers of attorney.

                  Subject to Section 3.04(d) hereof, in accordance with the
Servicing Standard, the Master Servicer shall advance or cause to be advanced
funds as necessary for the purpose of effecting the timely payment of taxes and
assessments on the Mortgaged Properties, which advances shall be Servicing
Advances reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.04(d), and further as provided in Section
3.05(a). Any cost incurred by the Master Servicer or by Sub-Servicers in
effecting the timely payment of taxes and assessments on a Mortgaged Property
shall not, for the purpose of calculating distributions to Certificateholders,
be added to the unpaid Stated Principal Balance of the related Mortgage Loan,
notwithstanding that the terms of such Mortgage Loan so permit.

                  Consistent with the terms of this Agreement, the Master
Servicer may waive, modify or vary any term of any Mortgage Loan or consent to
the postponement of strict compliance with any such term or in any manner grant
indulgence to any Mortgagor if such waiver, modification, postponement or
indulgence is in conformity with the Servicing Standard; provided, however,
that:

                  (A) the Master Servicer shall not make future advances (except
         as provided in Section 4.03);

                  (B) the Master Servicer shall not permit any modification with
         respect to any Mortgage Loan that would change the Mortgage Rate, defer
         or forgive the payment of any principal or interest payments, reduce
         the outstanding Stated Principal Balance (except for reductions
         resulting from actual payments of principal) or extend the final
         maturity date on such Mortgage Loan (unless as provided in Section
         3.02, (i) the Mortgagor is in default with respect to the Mortgage Loan
         or (ii) such default is, in the judgment of the Master Servicer,
         reasonably foreseeable); and

                  (C) the Master Servicer shall not consent to (i) partial
         releases of Mortgages, (ii) alterations, (iii) removal, demolition or
         division of properties subject to Mortgages, (iv) modification or (v)
         second mortgage subordination agreements with respect to any Mortgage
         Loan that would: (i) affect adversely the status of any Trust REMIC as
         a REMIC, (ii) cause any Trust REMIC to be subject to a tax on
         "prohibited transactions" or "contributions"

                                       70
<PAGE>

         pursuant to the REMIC Provisions, or (iii) both (x) effect an exchange
         or reissuance of such Mortgage Loan under Section 1001 of the Code (or
         Treasury regulations promulgated thereunder) and (y) cause any Trust
         REMIC constituting part of the Trust Fund to fail to qualify as a REMIC
         under the Code or the imposition of any tax on "prohibited
         transactions" or "contributions" after the Startup Day under the REMIC
         Provisions.

                  To the extent consistent with the terms of this Agreement,
including Section 2.03 and Section 2.05, the Master Servicer may waive (or
permit a Sub-Servicer to waive) a Prepayment Charge only under the following
circumstances: (i) such waiver is standard and customary in servicing similar
Mortgage Loans and (ii) such waiver relates to a default or a reasonably
foreseeable default and would, in the reasonable judgment of the Master
Servicer, maximize recovery of total proceeds taking into account the value of
such Prepayment Charge and the related Mortgage Loan.

                  The Master Servicer may delegate its responsibilities under
this Agreement; provided, however, that no such delegation shall release the
Master Servicer from the responsibilities or liabilities arising under this
Agreement. All references to Master Servicer in this Agreement shall be deemed
to include any Sub-Servicer duly appointed by the Master Servicer pursuant to
this Agreement.

                  SECTION 3.02. Collection of Certain Mortgage Loan Payments.

                  The Master Servicer shall make reasonable efforts to collect
all payments called for under the terms and provisions of the Mortgage Loans,
and shall, to the extent such procedures shall be consistent with this Agreement
and the terms and provisions of any applicable insurance policies, follow such
collection procedures as it would follow with respect to mortgage loans
comparable to the Mortgage Loans and held for its own account. Consistent with
the foregoing, the Master Servicer may in its discretion (i) waive any late
payment charge or, if applicable, penalty interest, or (ii) extend the due dates
for the Monthly Payments due on a Mortgage Note for a period of not greater than
180 days; provided that any extension pursuant to clause (ii) above shall not
affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder. The NIMS Insurer's prior written consent shall be
required for any modification, waiver or amendment if the aggregate number of
outstanding Mortgage Loans which have been modified, waived or amended exceeds
5% of the number of Mortgage Loans as of the Cut-off Date. In the event of any
such arrangement pursuant to clause (ii) above, the Master Servicer shall make
timely advances on such Mortgage Loan during such extension pursuant to Section
4.03 and in accordance with the amortization schedule of such Mortgage Loan
without modification thereof by reason of such arrangements.

                  Notwithstanding the foregoing, in the event that any Mortgage
Loan is in default or, in the judgment of the Master Servicer, such default is
reasonably foreseeable, the Master Servicer, consistent with the Servicing
Standard, may also waive, modify or vary any term of such Mortgage Loan
(including modifications that would change the Mortgage Rate, forgive the
payment of principal or interest or extend the final maturity date of such
Mortgage Loan), accept payment from the related Mortgagor of an amount less than
the Stated Principal Balance in final satisfaction of such Mortgage Loan, or
consent to the postponement of strict compliance with any such term or otherwise
grant indulgence to any Mortgagor (any and all such waivers, modifications,
variances, forgiveness

                                       71
<PAGE>

of principal or interest, postponements, or indulgences collectively referred to
herein as "forbearance"), provided, however, that in determining which course of
action permitted by this sentence it shall pursue, the Master Servicer shall
adhere to the Loss Mitigation Action Plan. The Master Servicer's analysis
supporting any forbearance and the conclusion that any forbearance meets the
standards of Section 3.01 and the Loss Mitigation Action Plan shall be reflected
in writing in the Mortgage File and shall be provided to the Certificate Insurer
upon request.

                  In the event that a shortfall in any collection on or
liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances
that were made by the Master Servicer in a manner not consistent with the terms
of the related Mortgage Note and this Agreement, the Master Servicer, upon
discovery or receipt of notice thereof, immediately shall deliver to the Trustee
for deposit in the Distribution Account from its own funds the amount of any
such shortfall and shall indemnify and hold harmless the Trust Fund, the
Trustee, the Depositor and any successor master servicer in respect of any such
liability. Such indemnities shall survive the termination or discharge of this
Agreement.

                  SECTION 3.03. [Reserved].

                  SECTION 3.04. Collection Account, Escrow Account and
                                Distribution Account.

                  (a) COLLECTION ACCOUNT. On behalf of the Trust Fund, the
Master Servicer shall segregate and hold all funds collected and received
pursuant to each Mortgage Loan separate and apart from any of its own funds and
general assets and shall establish and maintain in the name of the Trustee one
or more accounts (such account or accounts, the "Collection Account") in
accordance with this Section 3.04, held in trust for the benefit of the Trustee,
the Certificate Insurer and the Certificateholders.

                  (b) DEPOSITS TO THE COLLECTION ACCOUNT. On behalf of the Trust
         Fund, the Master Servicer shall deposit or cause to be deposited in the
         clearing account (which account must be an Eligible Account) in which
         it customarily deposits payments and collections 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 Master
         Servicer's receipt thereof, and shall thereafter deposit in the
         Collection Account, in no event more than two Business Days after the
         deposit of such funds into the clearing account, as and when received
         or as otherwise required hereunder, and retain therein, the following
         payments and collections received or made by it subsequent to the
         Cut-off Date with respect to the Mortgage Loans, or payments (other
         than Principal Prepayments) received by it on or prior to the Cut-off
         Date but allocable to a Due Period subsequent thereto:

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

                  (ii) all payments on account of interest on the Mortgage Loans
         and REO Properties adjusted to the Net Mortgage Rate;

                                       72
<PAGE>

                  (iii) all Insurance Proceeds and Liquidation Proceeds (other
         than proceeds to be held in the Escrow Account and applied to the
         restoration or repair of the Mortgaged Property or released to the
         Mortgagor in accordance with the Servicing Standard), Subsequent
         Recoveries and any amounts received in respect of the rental of any REO
         Property prior to REO Disposition;

                  (iv) all proceeds related to the purchase, substitution or
         repurchase of any Mortgage Loan or REO Property in accordance with
         Section 2.03;

                  (v) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.09 in connection with the deductible
         clause in any blanket hazard insurance policy, such deposit being made
         from the Master Servicer's own funds, without reimbursement therefor;

                  (vi) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.06 in connection with any losses

         Cut-off Date with respect to any Qualified Substitute Mortgage Loan
         shall be deemed to be the date of substitution);

                  (viii) any amounts required to be deposited by the Master
         Servicer pursuant to Section 4.03(b);

                  (ix) all Prepayment Charges collected by the Master Servicer,
         all Prepayment Charges payable by the Master Servicer pursuant to

         servicing activities on a daily basis, and in no event more than one
         Business Day after the Master Servicer's receipt thereof, and shall
         thereafter deposit in the Escrow Account, in no event more than two
         Business Days after the deposit of such funds into the clearing
         account, as and when received or as otherwise required hereunder, and

         Loans, for the purpose of effecting timely payment of any such items as
         required under the terms of this Agreement; and

                  (ii) all Insurance Proceeds which are to be applied to the
         restoration or repair of any Mortgaged Property.

         Certificateholders and the Certificate Insurer.

                  (f) TRUSTEE DEPOSITS TO THE DISTRIBUTION ACCOUNT. Upon

         deposited pursuant to Section 3.06 in connection with losses realized
         on Permitted Investments with respect to funds held in the Distribution
         Account. Furthermore, promptly upon receipt of any Stayed Funds,
         whether from the Master Servicer, a trustee in bankruptcy, or federal
         bankruptcy court or other source, the Trustee shall deposit such funds
         in the Distribution Account, subject to withdrawal thereof pursuant to
         Section 7.02(b) or as otherwise permitted hereunder.

                  (g) MASTER SERVICER TRANSFER OF FUNDS TO THE DISTRIBUTION

         Person pursuant to Section 3.23 and the terms of the related Advance

                  (x) to reimburse the NIMS Insurer, the Master Servicer (if the
         Master Servicer is not an Affiliate of the Seller) or the Trustee, as
         the case may be, for enforcement expenses reasonably incurred in

                  The foregoing requirements for withdrawal from the Collection
Account shall be exclusive. In the event the Master Servicer shall deposit in
the Collection Account any amount not required to be deposited therein, it may
at any time withdraw such amount from the Collection Account, any provision

on behalf of it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (vii),
(viii) and (xi) above. The Master Servicer shall provide written notification to

                  (ii) to reimburse the Master Servicer for any Servicing
         Advance made by the Master Servicer with respect to a related Mortgage

         termination of this Agreement; and

withdraw such amount from such Escrow Account, any provision herein to the
contrary notwithstanding. As part of its servicing duties, the Master Servicer
shall pay to the Mortgagor interest on funds in the Escrow Account, to the
extent required by the related Mortgage Loan or Applicable Regulations, and to
the extent that interest earned on funds in the Escrow Account is insufficient,
shall pay such interest from its own funds, without any reimbursement therefor.
The Master Servicer may pay to itself any excess interest on

                                       78

                                Distribution Account.

                  (a) The Master Servicer may direct any depository institution
maintaining the Collection Account, the Escrow Account (subject to Section
3.05(b)), and the REO Account and the Trustee may direct any depository
institution maintaining the Distribution Account (for purposes of this Section
3.06, each an "Investment Account"), to invest the funds in such Investment
Account in one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, (i) no later than the Business
Day immediately preceding the date on which such funds are required to be
withdrawn from such account pursuant to this Agreement, if a Person other than
the Trustee is the obligor thereon, and (ii) no later than the date on which
such funds are required to be withdrawn from such Investment Account pursuant to
this Agreement, if the Trustee is the obligor thereon. All such Permitted
Investments shall be held to maturity, unless payable on demand. Any investment
of funds in an Investment Account shall be made in the name of the Trustee (in
its capacity as such) or in the name of a nominee of the Trustee. The Trustee
shall be entitled to sole possession (except with respect to investment
direction of funds held in the Collection Account, the Escrow Account, and the
REO Account) over each such investment and (except with respect to the income on
funds held in the Collection Account, the Escrow Account and the REO Account)
the income thereon, and any certificate or other instrument evidencing any such
investment shall be delivered directly to the Trustee or its agent, together

                  (i) consistent with any notice required to be given
         thereunder, demand that payment thereon be made on the last day such
         Permitted Investment may otherwise mature hereunder in an amount equal
         to the lesser of (1) all amounts then payable thereunder and (2) the
         amount required to be withdrawn on such date; and

                  (ii) demand payment of all amounts due thereunder promptly
         upon determination by a Responsible Officer of the Trustee that such
         Permitted Investment would not constitute a Permitted Investment in
         respect of funds thereafter on deposit in the Investment Account.

                  (b) All income in the nature of interest from the investment
         of funds in the Collection Account, the Escrow Account (subject to
         Section 3.05(b)) and the REO Account shall be for the benefit of the
         Master Servicer as compensation for the Master Servicer's services
         pursuant to this Agreement. The Master Servicer shall deposit in the
         Collection Account, the Escrow Account, and the REO Account from its
         own funds the amount of any loss incurred in respect of any such
         Permitted Investment made with funds in such account immediately upon
         realization of such loss.

                  (c) All income in the nature of interest or earnings from the
         investment of funds in the Distribution Account shall be for the
         benefit of the Trustee as compensation for the Trustee's services
         pursuant to this Agreement. The Trustee shall deposit in the
         Distribution Account from its own funds the amount of any loss incurred
         on Permitted Investments in the Distribution Account.

                  (d) Funds on deposit in the Net WAC Rate Carryover Reserve
         Account may be invested in Permitted Investments in accordance with
         this Section 3.06 subject to any limitations set forth in Section 4.10
         and any investment earnings or interest paid shall accrue to the
         benefit of the party designated in such section and the party so
         designated shall deposit in the related account from its own funds the
         amount of any loss incurred on Permitted Investments in such account.

                  (e) Except as otherwise expressly provided in this Agreement,
         if any default occurs in the making of a payment due under any
         Permitted Investment, or if a default occurs in any other performance
         required under any Permitted Investment, the Trustee may and, subject
         to Section 8.01 and Section 8.02(a)(v), upon the request of the NIMS
         Insurer or the Holders of Certificates representing more than 50% of
         the Voting Rights allocated to any Class of Certificates, shall take
         such action as may be appropriate to enforce such payment or
         performance, including the institution and prosecution of appropriate
         proceedings.

                  (f) The Trustee or its Affiliates are permitted to receive
         compensation that could be deemed to be in the Trustee's economic
         self-interest for (i) serving as investment adviser, administrator,
         shareholder, servicing agent, custodian or sub-custodian with respect
         to certain of the Permitted Investments, (ii) using Affiliates to
         effect transactions in certain Permitted Investments and (iii)
         effecting transactions in certain Permitted Investments. Such
         compensation shall not be considered an amount that is reimbursable or
         payable pursuant to Section 3.05.

                  SECTION 3.07. Payment of Taxes, Insurance and Other Charges.

                                       80
<PAGE>

                  With respect to each Mortgage Loan, the Master Servicer shall
maintain accurate records reflecting the status of ground rents, taxes,
assessments, water rates and other charges which are or may become a lien upon
the Mortgaged Property and the status of fire and hazard insurance coverage and,
as to those Mortgage Loans subject to a voluntary escrow agreement, shall
obtain, from time to time, all bills for the payment of such charges (including
renewal premiums) and shall effect payment thereof prior to the applicable
penalty or termination date and at a time appropriate for securing maximum
discounts allowable, employing for such purpose deposits of the Mortgagor in the
Escrow Account which shall have been estimated and accumulated by the Master
Servicer in amounts sufficient for such purposes, as allowed under the terms of
the Mortgage or Applicable Regulations. The Master Servicer assumes full
responsibility for the timely payment of all such bills and shall effect timely
payments of all such bills irrespective of the Mortgagor's faithful performance
in the payment of same or the making of the Escrow Payments and shall make
Servicing Advances from its own funds to effect such payments. To the extent
that the Mortgage does not provide for Escrow Payments, the Master Servicer
shall use reasonable efforts consistent with the Servicing Standard to determine
that any such payments are made by the Mortgagor at the time they first become
due and shall ensure that the Mortgaged Property is not lost to a tax lien as a
result of nonpayment and that such Mortgaged Property is not left uninsured.

                  SECTION 3.08. Maintenance of Hazard Insurance.

                  The Master Servicer shall cause to be maintained for each
Mortgage Loan fire insurance with extended coverage on the related Mortgaged
Property in an amount which is at least equal to the least of (i) the current
principal balance of such Mortgage Loan, (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 and (iii) the maximum insurable value of
the improvements which are a part of such Mortgaged Property, 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 Master
Servicer shall also cause to be maintained fire 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
property and (ii) the outstanding principal balance of the related Mortgage
Loan, plus accrued interest at the Mortgage Rate and related Servicing Advances
(each measured at the time it became an REO Property). The Master 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 to be
collected by the Master 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 Master Servicer would follow in servicing loans held for its
own account, subject to the terms and conditions of the related Mortgage and
Mortgage Note) shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.05, if received in respect of a Mortgage Loan,
or in the REO Account, subject to withdrawal pursuant to Section 3.13, if
received in respect of an REO Property. Any cost incurred by the Master Servicer
in maintaining any such insurance shall not, for the purpose of calculating
distributions to Certificateholders, be added to the unpaid 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

                                       81
<PAGE>

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, the Master Servicer will
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 unpaid Stated
Principal Balance of the related Mortgage Loan; (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); and (iii) the maximum insurable value
of the improvements which are part of the related Mortgaged Property.

                  SECTION 3.09. Maintenance of Mortgage Blanket Insurance.

                  In the event that the Master Servicer shall obtain and
maintain a blanket policy with an insurer having a General Policy Rating of
"A:V" 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 sentences of Section 3.08, it being understood and agreed
that such policy may contain a deductible clause, in which case the Master
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 Section 3.08, and there shall have been one or more losses which
would have been covered by such policy, deposit to the Collection 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 Master Servicer agrees to prepare and
present, on behalf of itself, the Trustee, the Certificate Insurer and the
Certificateholders, claims under any such blanket policy in a timely fashion in
accordance with the terms of such policy.

                  SECTION 3.10. Fidelity Bond; Errors and Omissions Insurance.

                  The Master 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 Master 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 Mortgage Loans, unless the Master Servicer has obtained a waiver of such
requirements from Fannie Mae or Freddie Mac. The Master 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 Master Servicer has obtained a waiver
of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall
provide the Trustee, the Certificate Insurer and the NIMS Insurer (upon
reasonable request) with copies of any such insurance policies and fidelity
bond. The Master Servicer shall be deemed to have complied with this provision
if an Affiliate of the Master 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 Master 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 Master
Servicer shall also cause each Sub-Servicer to maintain a policy of insurance
covering errors and omissions and a fidelity bond which would meet such
requirements.

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

                                       82
<PAGE>

                  The Master Servicer will, to the extent it has knowledge of
any conveyance or prospective conveyance of any Mortgaged Property by any
Mortgagor (whether by absolute conveyance or by contract of sale, and whether or
not the Mortgagor remains or is to remain liable under the Mortgage Note and/or
the Mortgage), exercise its rights to accelerate the maturity of such Mortgage
Loan under the "due-on-sale" clause, if any, applicable thereto; provided,
however, that the Master Servicer shall not exercise any such rights if
prohibited by law from doing so. If the Master Servicer reasonably believes it
is unable under applicable law to enforce such "due-on-sale" clause, or if any
of the other conditions set forth in the proviso to the preceding sentence
apply, the Master Servicer is authorized to enter into an assumption and
modification agreement from or with the person to whom such property has been
conveyed or is proposed to be conveyed, pursuant to which such person becomes
liable under the Mortgage Note and, to the extent permitted by applicable state
law, the Mortgagor remains liable thereon. The Master Servicer is also
authorized 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 the Mortgagor and becomes liable under the Mortgage
Note, provided that no such substitution shall be effective unless such person
satisfies the underwriting criteria of the Master Servicer. In connection with
any assumption or substitution, the Master Servicer shall apply such
underwriting standards and follow such practices and procedures as shall be
normal and usual in its general mortgage servicing activities and as it applies
to other mortgage loans owned solely by it. The Master Servicer shall not take
or enter into any assumption and modification agreement, however, unless (to the
extent practicable in the circumstances) it shall have received confirmation, in
writing, of the continued effectiveness of any applicable hazard insurance
policy, or a new policy meeting the requirements of this Section is obtained.
Any fee collected by the Master Servicer in respect of an assumption or
substitution of liability agreement will be retained by the Master Servicer as
additional servicing compensation. In connection with any such assumption, no
material term of the Mortgage Note (including but not limited to the related
Mortgage Rate and the amount of the Monthly Payment) may be amended or modified,
except as otherwise required pursuant to the terms thereof or otherwise
permitted under Section 3.01. The Master Servicer shall notify the Trustee and
any respective Custodian that any such substitution or assumption agreement has
been completed by forwarding to the Trustee or to such Custodian, as the case
may be, the executed original of such substitution or assumption agreement,
which document 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.

                  Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Master Servicer shall not be deemed to be in default,
breach or any other violation of its obligations hereunder by reason of any
assumption of a Mortgage Loan by operation of law or by the terms of the
Mortgage Note or any assumption which the Master Servicer may be restricted by
law from preventing, for any reason whatever. For purposes of this Section 3.11,
the term "assumption" is deemed to also include a sale (of the Mortgaged
Property) subject to the Mortgage that is not accompanied by an assumption or
substitution of liability agreement.

                  SECTION 3.12. Realization Upon Defaulted Mortgage Loans.

                  (a) The Master Servicer shall, consistent with the Servicing
         Standard and the Loss Mitigation Action Plan, 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 pursuant to Section 3.02. The Master Servicer shall
         be responsible for all costs and expenses incurred by it in any such
         proceedings; provided, however, that such costs and expenses will be
         recoverable as Servicing Advances by the Master Servicer as
         contemplated in Section 3.05 and Section 3.13. The foregoing is subject
         to the provision that, in any case in which Mortgaged Property shall
         have suffered damage from an Uninsured Cause, the Master Servicer shall
         not be required to expend its own funds toward the restoration of such
         property unless it shall determine in its discretion that such
         restoration will increase the proceeds of liquidation of the related
         Mortgage Loan after reimbursement to itself for such expenses.

                  (b) Notwithstanding the foregoing provisions of this Section
         3.12 or any other provision of this Agreement, with respect to any
         Mortgage Loan as to which the Master Servicer has received actual
         notice of, or has actual knowledge of, the presence of any toxic or
         hazardous substance on the related Mortgaged Property, the Master
         Servicer shall not, on behalf of the Trustee, either (i) obtain title
         to such Mortgaged Property as a result of or in lieu of foreclosure or
         otherwise or (ii) otherwise acquire possession of, or take any other
         action with respect to, such Mortgaged Property, if, as a result of any
         such action, the Trustee, the Trust Fund or the Certificateholders
         would be considered to hold title to, to be a "mortgagee-in-possession"
         of, or to be an "owner" or "operator" of such Mortgaged Property within
         the meaning of the Comprehensive Environmental Response, Compensation
         and Liability Act of 1980, as amended from time to time, or any
         comparable law, unless the Master Servicer has also previously
         determined, based on its reasonable judgment and a report prepared by a
         Person who regularly conducts environmental audits using customary
         industry standards, that:

                  (1) such Mortgaged Property is in compliance with applicable
         environmental laws or, if not, that it would be in the best economic
         interest of the Trust Fund to take such actions as are necessary to
         bring the Mortgaged Property into compliance therewith; and

                  (2) there are no circumstances present at such Mortgaged
         Property relating to the use, management or disposal of any hazardous
         substances, hazardous materials, hazardous wastes, or petroleum-based
         materials for which investigation, testing, monitoring, containment,
         clean-up or remediation could be required under any federal, state or
         local law or regulation, or that if any such materials are present for
         which such action could be required, that it would be in the best
         economic interest of the Trust Fund to take such actions with respect
         to the affected Mortgaged Property.

                  Notwithstanding the foregoing, if such environmental audit
reveals, or if the Master Servicer has actual knowledge or notice, that such
Mortgaged Property contains such toxic or hazardous wastes or substances, the
Master Servicer shall not foreclose or accept a deed in lieu of foreclosure
without the prior written consent of the Certificate Insurer (which consent
shall not be unreasonably withheld) and the NIMS Insurer.

                                       84
<PAGE>

                  The cost of the environmental audit report contemplated by
this Section 3.12 shall be advanced by the Master Servicer, subject to the
Master Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.05(a)(v), such right of reimbursement being prior to the
rights of Certificateholders to receive any amount in the Collection Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

                  If the Master Servicer determines, as described above, that it
is in the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Master Servicer shall take such action as it deems to be in the best
economic interest of the Trust Fund; provided, however, that the Master Servicer
shall not proceed with foreclosure or acceptance of a deed in lieu of
foreclosure if the estimated costs of the environmental clean up, as estimated
in the environmental audit report, together with the Advances made by the Master
Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu
of foreclosure exceeds the estimated value of the Mortgaged Property. The cost
of any such compliance, containment, cleanup or remediation shall be advanced by
the Master Servicer, subject to the Master Servicer's right to be reimbursed
therefor from the Collection Account as provided in Section 3.05(a)(v), such
right of reimbursement being prior to the rights of Certificateholders to
receive any amount in the Collection Account received in respect of the affected
Mortgage Loan or other Mortgage Loans.

                  (c) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan,
will be applied in the following order of priority: FIRST, to reimburse the
Master Servicer or any Sub-Servicer for any related unreimbursed Servicing
Advances and Advances, pursuant to Section 3.05(a)(ii); SECOND, to accrued and
unpaid interest on the Mortgage Loan, to the date of the Final Recovery
Determination, or to the Due Date prior to the Distribution Date on which such
amounts are to be distributed if not in connection with a Final Recovery
Determination; and THIRD, as a recovery of principal of the Mortgage Loan. If
the amount of the recovery so allocated to interest is less than the full amount
of accrued and unpaid interest due on such Mortgage Loan, the amount of such
recovery will be allocated by the Master Servicer as follows: FIRST, to unpaid
Servicing Fees; and SECOND, to the balance of the interest then due and owing.
The portion of the recovery so allocated to unpaid Servicing Fees shall be
reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section
3.05(a)(ii).

                  SECTION 3.13. Title, Management and Disposition of REO
                                Property.

                  (a) The deed or certificate of sale of any REO Property shall
be taken in the name of the Trustee, or its nominee, in trust for the benefit of
the Certificateholders and the Certificate Insurer. Pursuant to the power of
attorney granted in Section 3.01, the Master Servicer is hereby authorized to
transfer the title of any REO Property taken in the name of the Trustee to a
third party purchaser pursuant to this Section 3.13 without further
documentation of its authority as attorney-in- fact for the Trustee on behalf of
the Trust. The Master Servicer, on behalf of the Trust Fund (and on behalf of
the Trustee for the benefit of the Certificateholders), shall either sell any
REO Property before the close of the third taxable year after the year the Trust
Fund acquires ownership of such

                                       85
<PAGE>

REO Property for purposes of Section 860G(a)(8) of the Code or request from the
Internal Revenue Service, no later than 60 days before the day on which the
three-year grace period would otherwise expire, an extension of the three-year
grace period, unless the Master Servicer shall have delivered to the Trustee,
the NIMS Insurer, the Certificate Insurer and the Depositor an Opinion of
Counsel, addressed to the Trustee, the NIMS Insurer, the Certificate Insurer and
the Depositor, to the effect that the holding by the Trust Fund of such REO
Property subsequent to three years after its acquisition will not result in the
imposition on any Trust REMIC of taxes on "prohibited transactions" thereof, as
defined in Section 860F of the Code, or cause any Trust REMIC to fail to qualify
as a REMIC under Federal law at any time that any Certificates are outstanding.
The Master Servicer shall manage, conserve, protect and operate each REO
Property for the benefit of the Certificateholders and solely for the purpose of
its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC of
any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions.

                  (b) The Master Servicer shall segregate and hold all funds
         collected and received in connection with the operation of any REO
         Property separate and apart from its own funds and general assets and
         shall establish and maintain with respect to REO Properties an account
         held in trust for the Trustee for the benefit of the Certificateholders
         and the Certificate Insurer (the "REO Account"), which shall be an
         Eligible Account. The Master Servicer shall be permitted to allow the
         Collection Account to serve as the REO Account, subject to separate
         ledgers for each REO Property. The Master Servicer shall be entitled to
         retain or withdraw any interest income paid on funds deposited in the
         REO Account.

                  (c) The Master Servicer shall have full power and authority,
         subject only to the specific requirements and prohibitions of this
         Agreement (including the Loss Mitigation Action Plan), to do any and
         all things in connection with any REO Property as are consistent with
         the manner in which the Master Servicer manages and operates similar
         property owned by the Master Servicer or any of its Affiliates, all on
         such terms and for such period as the Master Servicer deems to be in
         the best interests of Certificateholders and appropriate to effect the
         prompt disposition and sale of the REO Property. In connection
         therewith, the Master Servicer shall deposit, or cause to be deposited
         in the clearing account (which account must be an Eligible Account) in
         which it customarily deposits payments and collections 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
         Master Servicer's receipt thereof, and shall thereafter deposit in the
         REO Account, in no event more than two Business Days after the deposit
         of such funds into the clearing account, all revenues received by it
         with respect to an REO Property and shall withdraw therefrom funds
         necessary for the proper operation, management and maintenance of such
         REO Property including, without limitation:

                  (i) all insurance premiums due and payable in respect of such
         REO Property;

                  (ii) all real estate taxes and assessments in respect of such
         REO Property that may result in the imposition of a lien thereon; and

                  (iii) all costs and expenses necessary to maintain such REO
         Property.

                                       86
<PAGE>

                  To the extent that amounts on deposit in the REO Account with
respect to an REO Property are insufficient for the purposes set forth in
clauses (i) through (iii) above with respect to such REO Property, the Master
Servicer shall advance from its own funds such amount as is necessary for such
purposes if, but only if, the Master Servicer would make such advances if the
Master Servicer owned the REO Property and if in the Master Servicer's judgment,
the payment of such amounts will be recoverable from the rental or sale of the
REO Property.

                  Notwithstanding the Master Servicer's obligation to the
Certificateholders to manage and operate (including the collection of rents from
existing tenants and management of any leases acquired with the REO property to
the extent applicable) the REO Property from the date of acquisition until the
date of sale, neither the Master Servicer nor the Trustee shall knowingly:

                  (i) authorize the Trust Fund to enter into, renew or extend
         any New Lease with respect to any REO Property, if the New Lease by its
         terms will give rise to any income that does not constitute Rents from
         Real Property;

                  (ii) authorize any amount to be received or accrued under any
         New Lease other than amounts that will constitute Rents from Real
         Property;

                  (iii) authorize any construction on any REO Property, other
         than the completion of a building or other improvement thereon, and
         then only if more than ten percent of the construction of such building
         or other improvement was completed before default on the related
         Mortgage Loan became imminent, all within the meaning of Section
         856(e)(4)(B) of the Code; or

                  (iv) authorize any Person to Directly Operate any REO Property
         on any date more than 90 days after its date of acquisition by the
         Trust Fund;

unless, in any such case, the Master Servicer has obtained an Opinion of
Counsel, provided to the Trustee, the NIMS Insurer and the Certificate Insurer,
to the effect that such action will not cause such REO Property to fail to
qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code at any time that it is held by the Trust Fund, and (B) the Master
Servicer has received written notice from the Trustee that it has received
written consent from the Certificate Insurer and the NIMS Insurer that the
specific action may be taken.

                  The Master Servicer may contract with any Independent
Contractor for the operation and management of any REO Property, provided that:

                  (i) the terms and conditions of any such contract shall not be
         inconsistent herewith;

                  (ii) any such contract shall require, or shall be administered
         to require, that the Independent Contractor pay all costs and expenses
         incurred in connection with the operation and management of such REO
         Property, including those listed above and remit all related revenues
         (net of such costs and expenses) to the Master Servicer as soon as
         practicable, but

                                       87
<PAGE>

         in no event later than thirty days following the receipt thereof by
         such Independent Contractor;

                  (iii) none of the provisions of this Section 3.13(c) relating
         to any such contract or to actions taken through any such Independent
         Contractor shall be deemed to relieve the Master Servicer of any of its
         duties and obligations to the Trustee on behalf of the
         Certificateholders with respect to the operation and management of any
         such REO Property; and

                  (iv) the Master Servicer shall be obligated with respect
         thereto to the same extent as if it alone were performing all duties
         and obligations in connection with the operation and management of such
         REO Property.

                  The Master Servicer shall be entitled to enter into any
agreement with any Independent Contractor performing services for it related to
its duties and obligations hereunder for indemnification of the Master Servicer
by such Independent Contractor, and nothing in this Agreement shall be deemed to
limit or modify such indemnification. The Master Servicer shall be solely liable
for all fees owed by it to any such Independent Contractor, irrespective of
whether the Master Servicer's compensation pursuant to Section 3.18 is
sufficient to pay such fees. The Master Servicer shall not engage an Independent
Contractor to engage in any activities that the Master Servicer would not be
permitted to engage in itself in accordance with the other provisions of this
Agreement (including the Loss Mitigation Action Plan).

                  (d) In addition to the withdrawals permitted under Section
3.13(c), the Master Servicer may from time to time make withdrawals from the REO
Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid
Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse
itself or any Sub-Servicer for unreimbursed Servicing Advances and Advances made
in respect of such REO Property or the related Mortgage Loan. On the Master
Servicer Remittance Date, the Master Servicer shall withdraw from each REO
Account maintained by it and deposit into the Distribution Account in accordance
with Section 3.04(g)(ii), for distribution on the related Distribution Date in
accordance with Section 4.01, the income from the related REO Property received
during the prior calendar month, net of any withdrawals made pursuant to Section
3.13(c) or this Section 3.13(d).

                  (e) Subject to the time constraints set forth in Section
3.13(a) (including the constraint that the Master Servicer hold and manage each
REO Property "solely for the purpose of its prompt disposition") each REO
disposition shall be carried out by the Master Servicer at such price and upon
such terms and conditions as shall be in conformity with the requirements of the
Loss Mitigation Action Plan and as shall be normal and usual in its general
servicing activities for similar properties.

                  (f) The proceeds from the REO Disposition, net of any amount
required by law to be remitted to the Mortgagor under the related Mortgage Loan
and net of any payment or reimbursement to the Master Servicer or any
Sub-Servicer as provided above, shall be deposited in the Distribution Account
in accordance with Section 3.04(g)(ii) on the Master Servicer Remittance Date in
the month following the receipt thereof for distribution on the related
Distribution Date in

                                       88
<PAGE>

accordance with Section 4.01. Any REO Disposition shall be for cash only (unless
changes in the REMIC Provisions made subsequent to the Startup Day allow a sale
for other consideration).

                  SECTION 3.14. [Reserved].

                  SECTION 3.15. Reports of Foreclosure and Abandonment of
                                Mortgaged Properties.

                  The Master Servicer shall file information returns with
respect to the receipt of mortgage interest received in a trade or business,
reports of foreclosures and abandonments of any Mortgaged Property and
cancellation of indebtedness income with respect to any Mortgaged Property as
required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such
reports shall be in form and substance sufficient to meet the reporting
requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

                  SECTION 3.16. Optional Purchase of Defaulted Mortgage Loans.

                  (a)(i) The NIMS Insurer may, at its option, purchase a
Mortgage Loan which has become 90 or more days delinquent or for which the
Master Servicer has accepted a deed in lieu of foreclosure. Prior to purchase
pursuant to this Section 3.16(a)(i), the Master Servicer shall be required to
continue to make Advances pursuant to Section 4.03. The NIMS Insurer shall not
use any procedure in selecting Mortgage Loans to be repurchased which is
materially adverse to the interests of the Certificateholders. The NIMS Insurer
shall purchase such delinquent Mortgage Loan at a price equal to the Purchase
Price of such Mortgage Loan. Any such purchase of a Mortgage Loan pursuant to
this Section 3.16(a)(i) shall be accomplished by remittance to the Master
Servicer for deposit in the Collection Account of the amount of the Purchase
Price. The Trustee shall effectuate the conveyance of such delinquent Mortgage
Loan to the NIMS Insurer to the extent necessary, as requested, and the Trustee
shall promptly deliver all documentation to the NIMS Insurer.

                  (ii) During the first full calender month (but excluding the
last Business Day thereof) following a Mortgage Loan or related REO Property
becoming 90 days or more delinquent, the Master Servicer shall have the option,
but not the obligation to purchase from the Trust Fund any such Mortgage Loan or
related REO Property that is then still 90 days or more delinquent, which the
Master Servicer determines in good faith will otherwise become subject to
foreclosure proceedings (evidence of such determination to be delivered in
writing to the Trustee prior to purchase), at a price equal to the Purchase
Price. The Purchase Price for any Mortgage Loan or related REO Property
purchased hereunder shall be deposited in the Collection Account, and the
Trustee, upon written certification of such deposit, shall release or cause to
be released to the Master Servicer the related Mortgage File and the Trustee
shall execute and deliver such instruments of transfer or assignment, in each
case without recourse, as the Master Servicer shall furnish and as shall be
necessary to vest in the Master Servicer title to any Mortgage Loan or related
REO Property released pursuant hereto.

                  (b) If with respect to any delinquent Mortgage Loan or related
REO Property, the option of the Master Servicer set forth in the preceding
paragraph shall have arisen but the Master Servicer shall have failed to
exercise such option on or before the Business Day preceding the last

                                       89
<PAGE>

Business Day of the calender month following the calender month during which
such Mortgage Loan or related REO Property first became 90 days or more
delinquent, then such option shall automatically expire; provided, however, that
if any such Mortgage Loan or related REO Property shall cease to be 90 days or
more delinquent but then subsequently shall again become 90 days or more
delinquent, then the Master Servicer shall be entitled to another repurchase
option with respect to such Mortgage Loan or REO Property as provided in the
preceding paragraph.

                  SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files.

                  (a) Upon the payment in full of any Mortgage Loan, or the
receipt by the Master Servicer of a notification that payment in full shall be
escrowed in a manner customary for such purposes, the Master Servicer will
promptly notify the Trustee and any related Custodian by a certification in the
form of Exhibit E or such other form supplied by the Master Servicer provided
that it does not differ from the substantive content of Exhibit E (which
certification shall include a statement to the effect that all amounts received
or to be received in connection with such payment which are required to be
deposited in the Collection Account pursuant to Section 3.04(b) have been or
will be so deposited) of a Servicing Officer and shall request delivery to it of
the Mortgage File. Upon receipt of such certification and request, the Trustee
or such Custodian, as the case may be, shall promptly release (and in no event
more than three (3) Business Days thereafter) the related Mortgage File to the
Master Servicer. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Collection
Account or the Distribution Account.

                  (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Trustee and any related
Custodian shall, upon request of the Master Servicer and delivery to the Trustee
or such Custodian, as the case may be, of a Request for Release in the form of
Exhibit E or such other form supplied by the Master Servicer provided that it
does not differ from the substantive content of Exhibit E, release the related
Mortgage File to the Master Servicer, and the Trustee shall, at the direction of
the Master Servicer, execute such documents as shall be necessary to the
prosecution of any such proceedings and the Master Servicer shall retain such
Mortgage File in trust for the benefit of the Certificateholders. Such Request
for Release shall obligate the Master Servicer to return each and every document
previously requested from the Mortgage File to the Trustee or to such Custodian
when the need therefor by the Master Servicer no longer exists, unless the
Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the
Mortgage Loan have been deposited in the Collection Account or the Mortgage File
or such document has been delivered to an attorney, or to a public trustee or
other public official as required by law, for purposes of initiating or pursuing
legal action or other proceedings for the foreclosure of the Mortgaged Property
either judicially or non-judicially, and the Master Servicer has delivered to
the Trustee a certificate of a Servicing Officer certifying as to the name and
address of the Person to which such Mortgage File or such document was delivered
and the purpose or purposes of such delivery. Upon receipt of a certificate of a
Servicing Officer stating that such Mortgage Loan was liquidated and that all
amounts received or to be received in connection with such liquidation that are
required to be deposited into the Collection Account have been so deposited, or
that such Mortgage Loan has become an REO Property, upon request, a copy of the
Request for Release shall be released by the Trustee or such Custodian to the
Master Servicer.

                                       90
<PAGE>

                  (c) Upon written certification of a Servicing Officer, the
Trustee shall execute and deliver to the Master Servicer any court pleadings,
requests for trustee's sale or other documents reasonably necessary to the
foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal
action brought to obtain judgment against any Mortgagor on the Mortgage Note or
Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or
rights provided by the Mortgage Note or Mortgage or otherwise available at law
or in equity. Each such certification shall include a request that such
pleadings or documents be executed by the Trustee and a statement as to the
reason such documents or pleadings are required and that the execution and
delivery thereof by the Trustee will not invalidate or otherwise affect the lien
of the Mortgage, except for the termination of such a lien upon completion of
the foreclosure or trustee's sale.

                  (d) The Trustee and the Master Servicer may mutually agree on
policies and procedures (commercially reasonable in nature) to allow the
submission of any and all requests for the release of a Mortgage File
electronically with a digital signature or other identifier to designate the
Servicing Officer of the Master Servicer requesting such collateral.

                  SECTION 3.18. Servicing Compensation.

                  As compensation for the activities of the Master Servicer
hereunder, the Master Servicer shall be entitled to the Servicing Fee with
respect to each Mortgage Loan payable solely from payments of interest in
respect of such Mortgage Loan, subject to Section 4.03(e). In addition, the
Master Servicer shall be entitled to recover unpaid Servicing Fees out of
Insurance Proceeds or Liquidation Proceeds to the extent permitted by Section
3.05(a)(ii), out of general funds in the Collection Account to the extent
permitted by Section 3.05(a) and out of amounts derived from the operation and
sale of an REO Property to the extent permitted by Section 3.13. The right to
receive the Servicing Fee may not be transferred in whole or in part except in
connection with the transfer of all of the Master Servicer's responsibilities
and obligations under this Agreement.

                  Additional servicing compensation in the form of assumption
fees, late payment charges, insufficient funds fees, reconveyance fees and other
similar fees and charges (other than Prepayment Charges) shall be retained by
the Master Servicer only to the extent such fees or charges are received by the
Master Servicer. The Master Servicer shall also be entitled pursuant to Section
3.05(a)(vi) to withdraw from the Collection Account, pursuant to Section 3.04(h)
to withdraw from any Escrow Account and pursuant to Section 3.13(b) to withdraw
from any REO Account, as additional servicing compensation, interest or other
income earned on deposits therein, subject to Section 3.06. The Master Servicer
shall be required to pay all expenses incurred by it in connection with its
servicing activities hereunder (including premiums for the insurance required by
Section 3.08, Section 3.09 and Section 3.10, to the extent such premiums are not
paid by the related Mortgagors or by a Sub-Servicer, servicing compensation of
each Sub-Servicer, and to the extent provided in Section 8.05, the fees and
expenses of the Trustee) and shall not be entitled to reimbursement therefor
except as specifically provided herein.

                  SECTION 3.19. Statement as to Compliance.

                  The Master Servicer will deliver to the Trustee, the NIMS
Insurer, the Certificate Insurer, the Depositor and each Rating Agency on or
before March 15th of each calendar year

                                       91
<PAGE>

commencing in 2005, an Officers' Certificate in a form similar to Exhibit M
attached hereto agreeable to the parties hereto, stating, as to each signatory
thereof, that (i) a review of the activities of the Master 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 Master 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 officer and the nature and status thereof. Copies of any such
statement shall be provided by the Trustee to any Certificateholder and to any
Person identified to the Trustee as a prospective transferee of a Certificate,
upon the request and at the expense of the requesting party, provided that such
statement is delivered by the Master Servicer to the Trustee.

                  SECTION 3.20. Independent Public Accountants' Servicing
                                Report.

                  Not later than March 15th of each calendar year commencing in
2005, the Master Servicer, at its expense, shall cause a nationally recognized
firm of independent certified public accountants to furnish to the Master
Servicer a report stating that (i) it has obtained a letter of representation
regarding certain matters from the management of the Master Servicer which
includes an assertion that the Master 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 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 Sub- Servicers, 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 Sub-Servicers. Immediately upon receipt of such report,
the Master Servicer shall furnish a copy of such report to the Trustee, the NIMS
Insurer, the Certificate Insurer and each Rating Agency. Copies of such
statement shall be provided by the Trustee to any Certificateholder upon request
at the Master Servicer's expense, provided that such statement is delivered by
the Master Servicer to the Trustee. In the event such firm of independent
certified public accountants requires the Trustee to agree to the procedures
performed by such firm, the Master Servicer shall direct the Trustee in writing
to so agree; it being understood and agreed that the Trustee will deliver such
letter of agreement in conclusive reliance upon the direction of the Master
Servicer, and the Trustee has not made any independent inquiry or investigation
as to, and shall have no obligation or liability in respect of, the sufficiency,
validity or correctness of such procedures.

                  SECTION 3.21. Access to Certain Documentation.

                  The Master Servicer shall provide to the Office of Thrift
Supervision, the FDIC, and any other federal or state banking or insurance
regulatory authority that may exercise authority over any Certificateholder or
Certificate Owner, access to the documentation regarding the Mortgage Loans
required by applicable laws and regulations. Such access shall be afforded
without charge, but only upon reasonable request and during normal business
hours at the offices of the Master

                                       92
<PAGE>

Servicer designated by it. In addition, access to the documentation regarding
the Mortgage Loans will be provided to any Certificateholder or Certificate
Owner, the Trustee, the NIMS Insurer, the Certificate Insurer and to any Person
identified to the Master Servicer as a prospective transferee of a Certificate,
upon reasonable request during normal business hours at the offices of the
Master Servicer designated by it at the expense of the Person requesting such
access. In each case, access to any documentation regarding the Mortgage Loans
may be conditioned upon the requesting party's acknowledgment in writing of a
confidentiality agreement regarding any information that is required to remain
confidential under the Gramm-Leach-Bliley Act of 1999.

                  SECTION 3.22. PMI Policy; Claims Under the PMI Policy.

                  Notwithstanding anything to the contrary elsewhere in this
Agreement, the Master Servicer shall not agree to any modification or assumption
of a PMI Mortgage Loan or take any other action with respect to a PMI Mortgage
Loan that could result in denial of coverage under the PMI Policy. The Master
Servicer shall notify the PMI Insurer that the Trustee, on behalf of the
Certificateholders, is the Insured, as that term is defined in the PMI Policy,
of each PMI Mortgage Loan. The Master Servicer shall, on behalf of the Trustee,
prepare and file on a timely basis with the PMI Insurer, with a copy to the
Trustee, all claims which may be made under the PMI Policy with respect to the
PMI Mortgage Loans. Consistent with all rights and obligations hereunder, the
Master Servicer shall take all actions required under the PMI Policy as a
condition to the payment of any such claim. Any amount received from the PMI
Insurer with respect to any such PMI Mortgage Loan shall be deposited by the
Master Servicer into the Collection Account in accordance with Section 3.04(b).
The Trustee shall withdraw from the Distribution Account on each Distribution
Date and pay to the PMI Insurer the PMI Insurer Fee in accordance with the terms
of the PMI Policy.

                  SECTION 3.23. Advance Facility.

                  (a) The Master Servicer and/or the Trustee on behalf of the
Trust Fund, in either case, with the consent of the NIMS Insurer and the Master
Servicer in the case of the Trustee, is hereby authorized to enter into a
facility (an "Advance Facility") with any Person which provides that such Person
(an "Advancing Person") may fund Advances and/or Servicing Advances to the Trust
Fund under this Agreement, although no such facility shall reduce or otherwise
affect the Master Servicer's obligation to fund such Advances and/or Servicing
Advances. If the Master Servicer enters into such an Advance Facility pursuant
to this Section 3.23, upon reasonable request of the Advancing Person, the
Trustee shall execute a letter of acknowledgment, confirming its receipt of
notice of the existence of such Advance Facility. To the extent that an
Advancing Person funds any Advance or any Servicing Advance and provides the
Trustee with notice acknowledged by the Master Servicer that such Advancing
Person is entitled to reimbursement directly from the Trustee pursuant to the
terms of the Advance Facility, such Advancing Person shall be entitled to
receive reimbursement pursuant to this Agreement for such amount to the extent
provided in Section 3.23(b). Such notice from the Advancing Person must specify
the amount of the reimbursement, the Section of this Agreement that permits the
applicable Advance or Servicing Advance to be reimbursed and the section(s) of
the Advance Facility that entitle the Advancing Person to request reimbursement
from the Trustee, rather than the Master Servicer, and include the Master
Servicer's acknowledgment thereto or proof of an Event of Default under the
Advance Facility. The Trustee shall have no duty

                                       93
<PAGE>

or liability with respect to any calculation of any reimbursement to be paid to
an Advancing Person and shall be entitled to rely without independent
investigation on the Advancing Person's notice provided pursuant to this Section
3.23. An Advancing Person whose obligations hereunder are limited to the funding
of Advances and/or Servicing Advances shall not be required to meet the
qualifications of a Master Servicer or a Sub-Servicer pursuant to Section 6.06
hereof and will not be deemed to be a Sub-Servicer under this Agreement. If the
terms of a facility proposed to be entered into with an Advancing Person by the
Trust Fund would not materially and adversely affect the interests of any
Certificateholder, then the NIMS Insurer shall not withhold its consent to the
Trust Fund's entering such facility.

                  (b) If, pursuant to the terms of the Advance Facility, an
Advancing Person is entitled to reimbursement directly from the Trustee, then
the Master Servicer shall not reimburse itself therefor under Section
3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii)
prior to the remittance to the Trust Fund, but instead the Master Servicer shall
include such amounts in the applicable remittance to the Trustee made pursuant
to Section 3.04(g) to the extent of amounts on deposit in the Collection Account
on the related Master Servicer Remittance Date. The Trustee is hereby authorized
to pay to the Advancing Person reimbursements for Advances and Servicing
Advances from the Distribution Account, to the extent permitted under the terms
of the Advance Facility, to the same extent the Master Servicer would have been
permitted to reimburse itself for such Advances and/or Servicing Advances in
accordance with Section 3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or
Section 3.05(a)(vii), as the case may be, had the Master Servicer itself funded
such Advance or Servicing Advance. The Trustee is hereby authorized to pay
directly to the Advancing Person such portion of the Servicing Fee as the
parties to any Advance Facility agree to in writing delivered to the Trustee.

                  (c) All Advances and Servicing Advances made pursuant to the
terms of this Agreement shall be deemed made and shall be reimbursed on a "first
in first out" (FIFO) basis.

                  (d) In the event the Master Servicer is terminated pursuant to
Section 7.01, the Advancing Person shall succeed to the terminated Master
Servicer's right of reimbursement set forth in Section 7.02(c) to the extent of
such Advancing Person's financing of Advances or Servicing Advances hereunder
then remaining unreimbursed.

                  (e) Any amendment to this Section 3.23 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 3.23,
including amendments to add provisions relating to a successor master servicer,
may be entered into by the Trustee and the Master Servicer without the consent
of any Certificateholder but with the consent of the NIMS Insurer and written
confirmation from each Rating Agency that the amendment will not result in the
reduction or withdrawal of the then-current ratings of any outstanding Class of
Certificates (and with respect to the Insured Certificates, without regard to
the Policy) or any other notes secured by collateral which includes all or a
portion of the Class CE Certificates, the Class P Certificates and/or the
Residual Certificates, notwithstanding anything to the contrary in this
Agreement.

         Overcollateralization Target Amount, by the lesser of (x) the amount of
         such difference and (y) the Maximum I-LTZZ Uncertificated Interest

         Certificates and the Uncertificated Principal Balance of the REMIC I
         Regular Interest I-LTZZ shall be increased by such amount;

                  (ii) to the Holders of REMIC I Regular Interest I-LT1SUB,
         REMIC I Regular Interest I-LT1GRP, REMIC I Regular Interest I-LT2SUB,
         REMIC I Regular Interest I- LT2GRP and REMIC I Regular Interest I-LTXX,

                           (a) to the Holders of REMIC I Regular Interest I-LTAA
                  and REMIC I Regular Interest I-LTP, 98.00% of such remainder
                  (other than amounts payable under clause (iv) below), until
                  the Uncertificated Balance of such REMIC I Regular Interest is
                  reduced to zero, provided, however, that REMIC I Regular
                  Interest I-LTP shall not be reduced until the Distribution
                  Date immediately following the expiration of the latest
                  Prepayment Charge as identified on the Prepayment Charge
                  Schedule or any Distribution Date thereafter, at which point

                  On each Distribution Date, following the foregoing
distributions, an amount equal to the amount of Subsequent Recoveries deposited
into the Collection Account pursuant to Section 3.04 shall be applied to
increase the Certificate Principal Balance of the Class of Certificates with the

the related Cap Amount, from payments made under the related Cap Contract, in
each case up to the related Net WAC Rate Carryover Amount for such Distribution
Date;

                  SECOND, sequentially, to the Class M-1, Class M-2, Class M-3,
Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class M-10
Certificates, in that order, the related Cap Amount, in each case up to a
maximum amount equal to the related Net WAC Rate Carryover Amount for such
Distribution Date;

                  THIRD, concurrently, to each Class of Class A Certificates,
the related Net WAC Rate Carryover Amount remaining unpaid pursuant to clause
first above, on a PRO RATA basis based on such respective remaining Net WAC Rate

Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class M-10
Certificates, in that order, the related Net WAC Rate Carryover Amount remaining

                  On each Distribution Date, after the payment of any Net WAC
Rate Carryover Amounts on the Adjustable-Rate Certificates, any amounts
remaining in the Net WAC Rate Carryover Reserve Account (representing payments
received by the Trustee under the Cap Contracts), shall be payable to the
Trustee. For so long as any Adjustable-Rate Certificates are held by the Seller
or any of its Affiliates, the Trustee shall not distribute any Cap Amounts for
such Certificates to the Seller or any of its Affiliates and the Trustee will
retain any such amounts as additional compensation for its role in administering
the Cap Contracts.

                  On each Distribution Date, the Trustee shall withdraw any
amounts then on deposit in the Distribution Account that represent Prepayment
Charges collected by the Master Servicer, Prepayment Charges payable by the
Master Servicer pursuant to Section 2.03(b)(ii)(A) and Master Servicer
Prepayment Charge Payment Amounts payable by the Master Servicer pursuant to
Section 2.03(b)(ii)(B), subject to Section 2.03(b)(iii), in each case to the
extent not related to Principal Prepayments occurring after the related
Prepayment Period, and the Trustee shall distribute such amounts to the Holders
of the Class P Certificates. Such distributions shall not be applied to reduce
the Certificate Principal Balance of the Class P Certificates.

                  (c) All distributions made with respect to each Class of

Interests. Payments in respect of each Class of Certificates on each
Distribution Date will be made to the Holders of the respective Class of record
on the related Record Date (except as otherwise provided in Section 4.01(e) or
Section 9.01 respecting the final distribution on such Class), based on the
aggregate Percentage Interest represented by their respective Certificates, and

any such Holder at a bank or other entity having appropriate facilities
therefor, if such Holder shall have so notified the Trustee in writing at least
five Business Days prior to the Record Date immediately prior to such
Distribution Date, or otherwise by check mailed by first class mail to the
address of such Holder appearing in the Certificate Register. The final
distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the office of the Trustee
maintained for such purpose pursuant to Section 8.12 or such other location
specified in the notice to Certificateholders of such final distribution.
Payments to the Certificate Insurer on any Distribution Date shall be made by
wire transfer of immediately available funds to the account designated by the
Certificate Insurer under the Premium Letter (as defined in the Insurance
Agreement).

                  Each distribution with respect to a Book-Entry Certificate
shall be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the
Certificate Registrar, the Depositor or the Master Servicer shall have any
responsibility therefor except as otherwise provided by this Agreement or
applicable law.

                  (d) The rights of the Certificateholders to receive
distributions in respect of the Certificates, and all interests of the
Certificateholders in such distributions, shall be as set forth in this
Agreement. Neither the Holders of any Class of Certificates nor the Trustee nor
the Master Servicer shall in any way be responsible or liable to the Holders of
any other Class of Certificates in respect of amounts properly previously
distributed on the Certificates.

                  (e) Except as otherwise provided in Section 9.01, whenever the
Trustee expects that the final distribution with respect to any Class of
Certificates will be made on the next Distribution Date, the Trustee shall, no
later than five (5) days after the related Determination Date, mail to the
Certificate Insurer and each Holder on such date of such Class of Certificates a
notice to the effect that:

                (i) the Trustee expects that the final distribution with respect
         to such Class of Certificates will be made on such Distribution Date,
         but only upon presentation and surrender of such Certificates at the
         office of the Trustee therein specified or its agent; and

               (ii) no interest shall accrue on such Certificates from and after
         the end of the related Interest Accrual Period.

                  Any funds not distributed to any Holder or Holders of
Certificates of such Class on such Distribution Date because of the failure of
such Holder or Holders to tender their Certificates shall, on such date, be set
aside and held in trust by the Trustee and credited to the account of the
appropriate non-tendering Holder or Holders. If any Certificates as to which
notice has been given pursuant to this Section 4.01(e) shall not have been
surrendered for cancellation within six months after the time specified in such
notice, the Trustee shall mail a second notice to the remaining non- tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been surrendered for
cancellation, the Trustee shall, directly or through an agent, mail a final
notice to remaining non-tendering Certificateholders concerning surrender of
their Certificates but shall continue to hold any remaining funds for the
benefit of non-tendering Certificateholders. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets remaining in such trust fund. If within one year after
the final notice any such Certificates shall not have been surrendered for
cancellation, any amounts which were paid by the Certificate Insurer under the
Policy shall be reimbursed to the Certificate Insurer and the Trustee shall pay
to Deutsche Bank Securities Inc. all such amounts, and all rights of
non-tendering Certificateholders in or to such amounts shall thereupon cease. No
interest shall accrue or be payable to any Certificateholder on any amount held
in trust by the Trustee as a result of such Certificateholder's failure to
surrender its Certificate(s) for final payment thereof in accordance with this
Section 4.01(e).

                  (f) Notwithstanding anything to the contrary herein, (i) in no
event shall the Certificate Principal Balance of a Class A Certificate or a
Mezzanine Certificate be reduced more than once in respect of any particular
amount both (a) allocated to such Certificate in respect of Realized Losses
pursuant to Section 4.04 and (b) distributed to the Holder of such Certificate
in reduction of the Certificate Principal Balance thereof pursuant to this
Section 4.01 from Net Monthly Excess Cashflow and (ii) in no event shall the
Uncertificated Balance of a REMIC I Regular Interest be reduced more than once
in respect of any particular amount both (a) allocated to such REMIC I Regular
Interest in respect of Realized Losses pursuant to Section 4.04 and (b)
distributed on such REMIC I Regular Interest in reduction of the Uncertificated
Balance thereof pursuant to this Section 4.01.

                  (g) On each Distribution Date for which there exists a
Guaranteed Distributions Shortfall, in addition to making the distributions
required pursuant to Section 4.01(a) through (g), the Trustee shall withdraw
from the Distribution Account any amount therein that was transferred from the
Policy Payments Account to the Distribution Account pursuant to Section 12.04(b)
and distribute (i) to the Holders of the Class A-1 Certificates, the amount, if
any, by which the amount distributed as interest to the Class A-1 Certificates,
pursuant to the priority of payment set forth in Section 4.01(a), is less than
the related Senior Interest Distribution Amount for the Class A-1 Certificates
for such Distribution Date and (ii) on the Final Distribution Date (as defined
in the Policy), to the Holders of the Class A-1 Certificates, the Certificate
Principal Balance of the Class A-1 Certificates to the extent unpaid on the

to the Trustee for deposit in the Distribution Account an amount equal to the
aggregate amount of Advances, if any, to be made in respect of the Mortgage
Loans and REO Properties for the related Distribution Date either (i) from its
own funds, (ii) from the Collection Account, to the extent of funds held therein
for future distribution (in which case, it will cause to be made an appropriate
entry in the records of the Collection Account that amounts held for future
distribution have been, as permitted by this Section 4.03, used by the Master
Servicer in discharge of any such Advance) or (iii) in the form of any
combination of (i) and (ii) aggregating the total amount of Advances to be made
by the Master Servicer with respect to the Mortgage Loans and REO Properties.
Any amounts held for future distribution used by the Master Servicer to make an
Advance as permitted in the preceding sentence or withdrawn by the Master
Servicer as permitted in Section 3.05(a)(vii) in reimbursement of Advances
previously made shall be appropriately reflected in the Master Servicer's
records and replaced by the Master Servicer by deposit in the Collection Account
on or before any future Master Servicer Remittance Date to the extent that the
Available Funds for the related Distribution Date (determined without regard to
Advances to be made on the Master Servicer Remittance Date) shall be less than
the total amount that would be distributed to the Classes of Certificateholders
pursuant to Section 4.01 on such Distribution Date if such amounts held for
future distributions had not been so used to make Advances. The Trustee will
provide notice to the Master Servicer, the Certificate Insurer and the NIMS
Insurer by telecopy by the close of business on any Master Servicer Remittance
Date in the event that the amount remitted by the Master Servicer to the Trustee
on such date is less than the Advances required to be made by the Master
Servicer for the related Distribution Date.

                  (c) The obligation of the Master Servicer to make such
Advances is mandatory, notwithstanding any other provision of this Agreement but
subject to (d) below, and, with respect to any Mortgage Loan or REO Property,

Agreement, except as otherwise provided in this Section.

                  (d) Notwithstanding anything herein to the contrary, no
Advance or Servicing Advance shall be required to be made hereunder by the
Master Servicer if such Advance or Servicing Advance would, if made, constitute
a Nonrecoverable Advance or Nonrecoverable Servicing Advance. The determination
by the Master Servicer that it has made a Nonrecoverable Advance or a
Nonrecoverable Servicing Advance or that any proposed Advance or Servicing
Advance, if made, would constitute a Nonrecoverable Advance or Nonrecoverable
Servicing Advance, respectively,

                                      110

Interest") equal to the lesser of (i) the aggregate of the Prepayment Interest
Shortfalls for the related Distribution Date resulting solely from Principal
Prepayments during the related Prepayment Period and (ii) the amount of its
aggregate Servicing Fee for the most recently ended calendar month. The Master
Servicer shall not have the right to reimbursement for any amounts remitted to
the Trustee in respect of Prepayment Interest Shortfalls. Such amounts so
remitted shall be included in the Available Funds and distributed therewith on
the next Distribution Date. The Master Servicer shall not be obligated to pay
any amounts with respect to Relief Act Interest Shortfalls.

                  SECTION 4.04. Allocation of Realized Losses.

                  (a) On or before each Determination Date, the Master Servicer
shall determine as to each Mortgage Loan and REO Property: (i) the total amount
of Realized Losses, if any, incurred in connection with any Final Recovery
Determinations made during the related Prepayment Period; (ii) whether and the
extent to which such Realized Losses constituted Bankruptcy Losses; and (iii)
the respective portions of such Realized Losses allocable to interest and
allocable to principal. On or before each Determination Date, the Master
Servicer shall also determine as to each Mortgage Loan: (A) the total amount of
Realized Losses, if any, incurred in connection with any Deficient Valuations
made during the related Prepayment Period; and (B) the total amount of Realized
Losses, if any, incurred in connection with Debt Service Reductions in respect
of Monthly Payments due during the related Due Period. The information described
in the two preceding sentences that is to be supplied by the Master Servicer
shall be evidenced by an Officers' Certificate delivered to the Trustee and the
Certificate Insurer by the Master Servicer on the Master Servicer Reporting Date
immediately following the end of (x) in the case of Bankruptcy Losses allocable
to interest, the Due Period during which any such Realized Loss was incurred,
and (y) in the case of all other Realized Losses, the Prepayment Period during
which any such Realized Loss was incurred.

                  (b) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee on each Distribution Date as follows: FIRST, in
reduction of interest accrued on and otherwise distributable to the Class CE
Certificates to the extent of Net Monthly Excess Cashflow used to pay principal
on the Class A Certificates and the Mezzanine Certificates under clause (i) of
Section 4.01 hereof; SECOND, in reduction of interest accrued on and otherwise
distributable to the Class CE Certificates to the extent of Net Monthly Excess
Cashflow available for distribution pursuant to clauses (ii) through (vi) of
Section 4.01(a)(4) hereof; and THIRD, in reduction of the Certificate Principal
Balance of the Class CE Certificates (determined after taking into account all
distributions made on the Certificates on such Distribution Date), until the
Certificate Principal Balance thereof has been reduced to zero. If on any
Distribution Date, after all distributions are made by the Trustee pursuant to
Section 4.01 hereof, the aggregate Certificate Principal Balance of the Class A
Certificates, the Mezzanine Certificates and the Class P certificates exceeds
the sum of the Stated Principal Balance of the Mortgage Loans as of the last day
of the related Due Period (after taking into account prepayments during the
related Prepayment Period), the amount of such excess shall

                                      111
<PAGE>

be allocated: FIRST, to the Class M-10 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; SECOND, to the Class M-9
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; THIRD, to the Class M-8 Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; FOURTH, to the Class M-7 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero; FIFTH,
to the Class M-6 Certificates, until the Certificate Principal Balance thereof
has been reduced to zero; SIXTH, to the Class M-5 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; SEVENTH, to the
Class M-4 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; EIGHTH, to the Class M-3 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero, NINTH, to the Class M-2
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero and TENTH, to the Class M-1 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero. All Realized Losses to be
allocated to the Certificate Principal Balances of all Classes on any
Distribution Date shall be so allocated after the actual distributions to be
made on such date as provided above.

                  Any such allocation to a Class of Mezzanine Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof (after the actual distributions to be made on such Distribution Date
pursuant to Section 4.01 hereof) by the amount so allocated; any allocation of
Realized Losses to a Class CE Certificate shall be made by reducing the amount
otherwise payable in respect thereof pursuant to Section 4.01(a)(4)(V). No
allocations of any Realized Losses shall be made to the Certificate Principal
Balances of the Class A Certificates or the Class P Certificates.

                  As used herein, an allocation of a Realized Loss on a "PRO
RATA basis" among two or more specified Classes of Certificates means an
allocation on a PRO RATA basis, among the various Classes so specified, to each
such Class of Certificates on the basis of their then outstanding Certificate
Principal Balances prior to giving effect to distributions to be made on such
Distribution Date. All 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.

                  (c)(i) The REMIC I Marker Percentage of all Realized Losses on
the Mortgage Loans shall be allocated by the Trustee on each Distribution Date
to the following REMIC I Regular Interests in the specified percentages, as
follows: FIRST, to Uncertificated Interest payable to the REMIC I Regular
Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate amount
equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively;
SECOND, to the Uncertificated Balances of the REMIC I Regular Interest I-LTAA
and REMIC I Regular Interest I- LTZZ up to an aggregate amount equal to the
REMIC I Principal Loss Allocation Amount, 98% and 2%, respectively; THIRD, to
the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM10 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM10 has been reduced to zero; FOURTH, to the Uncertificated Balances of
REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM9 and REMIC I
Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC I Regular Interest I-LTM9 has been reduced to zero;FIFTH, to
the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM8 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated

                                      112
<PAGE>

Balance of REMIC I Regular Interest I-LTM8 has been reduced to zero; SIXTH, to
the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM7 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM7 has been reduced to zero; SEVENTH, to the Uncertificated Balances of
REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM6 and REMIC I
Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC I Regular Interest I-LTM6 has been reduced to zero; EIGHTH, to
the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM5 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest I-
LTM5 has been reduced to zero; NINTH, to the Uncertificated Balances of REMIC I
Regular Interest I-LTAA, REMIC I Regular Interest I-LTM4 and REMIC I Regular
Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance
of REMIC I Regular Interest I-LTM4 has been reduced to zero; TENTH, to the
Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM3 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM3 has been reduced to zero; ELEVENTH, to the Uncertificated Balances of
REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM2 and REMIC I
Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC I Regular Interest I-LTM2 has been reduced to zero; and
TWELFTH, to the Uncertificated Balances of REMIC I Regular Interest I-LTAA,
REMIC I Regular Interest I- LTM1 and REMIC I Regular Interest I-LTZZ, 98%, 1%
and 1%, respectively, until the Uncertificated Balance of REMIC I Regular
Interest I-LTM1 has been reduced to zero.

                  (ii) The REMIC I Sub WAC Allocation Percentage of all Realized
Losses shall be applied after all distributions have been made on each
Distribution Date: FIRST, so as to keep the Uncertificated 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 Class A 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 I-LTXX.

                  SECTION 4.05. Compliance with Withholding Requirements.

                  Notwithstanding any other provision of this Agreement, the
Trustee shall comply with all federal withholding requirements respecting
payments to Certificateholders of interest or original issue discount that the
Trustee reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee does withhold any amount from interest or original issue discount
payments or advances thereof to any Certificateholder pursuant to federal
withholding requirements, the Trustee shall indicate the amount withheld to such
Certificateholders.

                  SECTION 4.06. Commission Reporting.

                                      113
<PAGE>

                  (a) The Trustee shall reasonably cooperate with the Depositor
in connection with the Trust's satisfying the reporting requirements under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Trustee
shall prepare on behalf of the Trust any Forms 8-K and 10-K customary for
similar securities as required by the Exchange Act and the Rules and Regulations
of the Commission thereunder, and the Depositor shall sign (or shall cause
another entity acceptable to the Commission to sign) and the Trustee shall file
(via the Commission's Electronic Data Gathering and Retrieval System) such forms
on behalf of the Depositor (or such other entity). The Depositor hereby grants
to the Trustee a limited power of attorney to execute any Form 8-K and file each
such document on behalf of the Depositor. Such power of attorney shall continue
until 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.
Notwithstanding anything herein to the contrary, the Depositor, and not the
Trustee, shall be responsible for executing each Form 10-K filed on behalf of
the Trust.

                  (b) Each Form 8-K shall be filed by the Trustee within 15 days
after each Distribution Date, with a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
March 30th of each year (or such earlier date as may be required by the Exchange
Act and the Rules and Regulations of the Commission), the Trustee shall file a
Form 10- K, in substance as required by applicable law or applicable Commission
staff's interpretations. Such Form 10-K shall include as exhibits the Master
Servicer's annual statement of compliance described under Section 3.19 and the
accountant's report described under Section 3.20, in each case to the extent
they have been timely delivered to the Trustee. If they are not so 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
Trustee shall have no liability with respect to any failure to properly prepare
or file such periodic reports resulting from or relating to the Trustee's
inability or failure to obtain any information not resulting from its own
negligence or willful misconduct. The Form 10-K shall also include a
certification in the form attached hereto as Exhibit J-1 (the "Certification"),
which shall be signed by the senior officer of the Depositor in charge of
securitization.

                  (c) In addition, the Trustee shall sign a certification (in
the form attached hereto as Exhibit J-2) for the benefit of the Depositor and
its officers, directors and Affiliates regarding certain aspects of items 1
through 3 of the Certification (provided, however, that the Trustee shall not
undertake an analysis of the accountant's report attached as an exhibit to the
Form 10-K). The Trustee's certification shall be delivered to the Depositor by
no later than March 18th of each year (or if such day is not a Business Day, the
immediately preceding Business Day) and the Depositor shall deliver the
Certification to the Trustee for filing no later than March 20th of each year
(or if such day is not a Business Day, the immediately preceding Business Day).

                  In addition, 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 4.06 or the
Trustee's negligence, bad faith or willful misconduct in connection therewith.
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,

                                      114
<PAGE>

judgments and other costs and expenses arising out of or based upon a breach of
the Depositor's obligations under this Section 4.06 or the Depositor's
negligence, bad faith or willful misconduct in connection therewith. 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 4.06
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
of the Depositor on the one hand and the Trustee on the other.

                  (d) Upon any filing with the Commission, the Trustee shall
promptly deliver to the Depositor a copy of any executed report, statement or
information.

                  (e) Prior to January 30th of the first year in which the
Trustee is able to do so under applicable law, the Trustee shall file a Form 15
Suspension Notification with respect to the Trust.

                  (f) To the extent that, following the Closing Date, the
Depositor certifies that reports and certifications differing from those
required under this Section 4.06 comply with the reporting requirements under
the Exchange Act, the Trustee hereby agrees that it will reasonably cooperate to
amend the provisions of this Section 4.06 (in accordance with Section 11.01) in
order to comply with such amended reporting requirements and such amendment of
this Section 4.06. Any such amendment may result in the reduction of the reports
filed by the Depositor under the Exchange Act. Notwithstanding the foregoing,
the Trustee shall not be obligated to enter into any amendment pursuant to this
Section that adversely affects its obligations and immunities under this
Agreement.

                  SECTION 4.07. [Reserved].

                  SECTION 4.08. [Reserved].

                  SECTION 4.09. [Reserved].

                  SECTION 4.10 Net WAC Rate Carryover Reserve Account.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain with itself, as agent for the Trustee, a separate,
segregated trust account titled, "Net WAC Rate Carryover Reserve Account,
Deutsche Bank National Trust Company, as Trustee, in trust for the registered
Holders of Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through
Certificates, Series 2004-R8." The Trustee shall deposit into the Net WAC Rate
Carryover Reserve Account any payments received by it (i) under the Cap
Contracts for the benefit of the Holders of the Adjustable- Rate Certificates
and (ii) pursuant to Section 4.01(a)(4)(iv).

                  (b) On each Distribution Date as to which there is a Net WAC
Rate Carryover Amount payable to the Class A Certificates or the Mezzanine
Certificates, the Trustee has been directed by the Class CE Certificateholders
to, and therefore will, deposit into the Net WAC Rate Carryover Reserve Account
the amount of such Net WAC Rate Carryover Amount, after taking into

                                      115
<PAGE>

account amounts received under the Cap Contracts, rather than distributing such
amounts to the Class CE Certificateholders. On each such Distribution Date, the
Trustee shall hold all such amounts for the benefit of the Holders of the Class
A Certificates and the Mezzanine Certificates, and will distribute such amounts
to the Holders of the Class A Certificates and the Mezzanine Certificates in the
amounts and priorities set forth in Section 4.01(a).

                  (c) For federal and state income tax purposes, the Class CE
Certificateholders will be deemed to be the owners of the Net WAC Rate Carryover
Reserve Account and all amounts deposited into the Net WAC Rate Carryover
Reserve Account shall be treated as amounts distributed by REMIC II to the
Holders of the Class CE Certificates. Upon the termination of the Trust, or the
payment in full of the Class A Certificates and the Mezzanine Certificates, all
amounts remaining on deposit in the Net WAC Rate Carryover Reserve Account will
be released by the Trust and distributed to the Class CE Certificateholders or
their designees. The Net WAC Rate Carryover Reserve Account will be part of the
Trust but not part of any REMIC and any payments to the Holders of the Class A
Certificates or the Mezzanine Certificates of Net WAC Rate Carryover Amounts
will not be payments with respect to a "regular interest" in a REMIC within the
meaning of Code Section 860(G)(a)(1).

                  (d) By accepting a Class CE Certificate, each Class CE
Certificateholder hereby agrees to direct the Trustee, and the Trustee hereby is
directed, to deposit into the Net WAC Rate Carryover Reserve Account the amounts
described above on each Distribution Date as to which there is any Net WAC Rate
Carryover Amount rather than distributing such amounts to the Class CE
Certificateholders. By accepting a Class CE Certificate, each Class CE
Certificateholder further agrees that such direction is given for good and
valuable consideration, the receipt and sufficiency of which is acknowledged by
such acceptance.

                  (e) At the written direction of the Holders of a majority in
Percentage Interest in the Class CE Certificates, the Trustee shall direct any
depository institution maintaining the Net WAC Rate Carryover Reserve Account to
invest the funds in such account in one or more Permitted Investments bearing
interest or sold at a discount, and maturing, unless payable on demand, (i) no
later than the Business Day immediately preceding the date on which such funds
are required to be withdrawn from such account pursuant to this Agreement, if a
Person other than the Trustee or an Affiliate manages or advises such
investment, and (ii) no later than the date on which such funds are required to
be withdrawn from such account pursuant to this Agreement, if the Trustee or an
Affiliate manages or advises such investment. If no investment direction of the
Holders of a majority in Percentage Interest in the Class CE Certificates with
respect to the Net WAC Rate Carryover Reserve Account is received by the
Trustee, the Trustee shall invest the funds in the Deutsche Bank Institutional
Cash Management Fund 541 so long as it is a Permitted Investment. Interest
earned on such investment shall be deposited into the Net WAC Rate Carryover
Reserve Account.

                  (f) For federal income tax return and information reporting,
the value assigned to the right of the Holders of the Class A-1 Certificates,
Group II Certificates and the Mezzanine Certificates to receive payments from
the Net WAC Rate Carryover Reserve Account in respect of any Net WAC Rate
Carryover Amount will be $1,400,000, $500,000 and $820,000, respectively.

                                THE CERTIFICATES

                  SECTION 5.01. The Certificates.

                  (a) The Certificates in the aggregate will represent the
entire beneficial ownership interest in the Mortgage Loans and all other assets
included in REMIC I. At the Closing Date, the aggregate Certificate Principal
Balance of the Certificates will equal the aggregate Stated Principal Balance of
the Mortgage Loans.

                  The Certificates will be substantially in the forms annexed
hereto as Exhibits A-1 through A-18. The Certificates of each Class will be
issuable in registered form only, in denominations of authorized Percentage
Interests as described in the definition thereof. Each Certificate will share
ratably in all rights of the related Class.

                  Upon original issue, the Certificates shall be executed and
delivered by the Trustee and the Trustee shall cause the Certificates to be
authenticated by the Certificate Registrar to or upon the order of the
Depositor. The Certificates shall be executed and attested by manual or
facsimile signature on behalf of the Trustee by an authorized signatory.
Certificates bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Trustee shall bind the Trustee
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Certificates or did not
hold such offices at the date of such Certificates. No Certificate shall be
entitled to any benefit under this Agreement or be valid for any purpose, unless
there appears on such Certificate a certificate of authentication substantially
in the form provided herein executed by the Certificate Registrar by manual
signature, and such certificate of authentication shall be conclusive evidence,
and the only evidence, that such Certificate has been duly authenticated and
delivered hereunder. All Certificates shall be dated the date of their
authentication.

                  (b) The Class A Certificates and the Mezzanine Certificates
shall initially be issued as one or more Certificates held by the Book-Entry
Custodian or, if appointed to hold such Certificates as provided below, the
Depository, and registered in the name of the Depository or its nominee and,
except as provided below, registration of such Certificates may not be
transferred by the Trustee except to another Depository that agrees to hold such
Certificates for the respective Certificate Owners with Ownership Interests
therein. The Certificate Owners shall hold their respective Ownership Interests
in and to such Certificates through the book-entry facilities of the Depository
and, except as provided below, shall not be entitled to definitive, fully
registered Certificates ("Definitive Certificates") in respect of such Ownership
Interests. All transfers by Certificate Owners of their respective Ownership
Interests in the Book-Entry Certificates shall be made in accordance with the
procedures established by the Depository Participant or brokerage firm
representing such Certificate Owner. Each Depository Participant shall only
transfer the Ownership Interests in the Book-Entry Certificates of Certificate
Owners it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. The Trustee is hereby
initially appointed as the Book-Entry Custodian and hereby agrees to act as such
in accordance herewith and in accordance with the agreement that it has with the
Depository authorizing it to act

                                      117
<PAGE>

as such. The Book-Entry Custodian may, and if it is no longer qualified to act
as such, the Book- Entry Custodian shall, appoint, by a written instrument
delivered to the Depositor, the Master Servicer, the Trustee (if the Trustee is
not the Book-Entry Custodian) and any other transfer agent (including the
Depository or any successor Depository), to act as Book-Entry Custodian under
such conditions as the predecessor Book-Entry Custodian and the Depository or
any successor Depository may prescribe, provided that the predecessor Book-Entry
Custodian shall not be relieved of any of its duties or responsibilities by
reason of any such appointment of other than the Depository. If the Trustee
resigns or is removed in accordance with the terms hereof, if it so elects, the
Depository shall immediately succeed to its predecessor's duties as Book-Entry
Custodian. The Depositor shall have the right to inspect, and to obtain copies
of, any Certificates held as Book-Entry Certificates by the Book-Entry
Custodian.

                  The Trustee, the Master Servicer and the Depositor may for all
purposes (including the making of payments due on the Book-Entry Certificates)
deal with the Depository as the authorized representative of the Certificate
Owners with respect to the Book-Entry Certificates for the purposes of
exercising the rights of Certificateholders hereunder. The rights of Certificate
Owners with respect to the Book-Entry Certificates shall be limited to those
established by law and agreements between such Certificate Owners and the
Depository Participants and brokerage firms representing such Certificate
Owners. Multiple requests and directions from, and votes of, the Depository as
Holder of the Book-Entry Certificates with respect to any particular matter
shall not be deemed inconsistent if they are made with respect to different
Certificate Owners. The Trustee may establish a reasonable record date in
connection with solicitations of consents from or voting by Certificateholders
and shall give notice to the Depository of such record date.

                  If (i)(A) the Depositor advises the Trustee in writing that
the Depository is no longer willing or able to properly discharge its
responsibilities as Depository, and (B) the Depositor is unable to locate a
qualified successor or (ii) after the occurrence of a Master Servicer Event of
Default, Certificate Owners representing in the aggregate not less than 51% of
the Ownership Interests of the Book-Entry Certificates advise the Trustee
through the Depository, in writing, that the continuation of a book-entry system
through the Depository is no longer in the best interests of the Certificate
Owners, the Trustee shall notify all Certificate Owners, through the Depository,
of the occurrence of any such event and of the availability of Definitive
Certificates to Certificate Owners requesting the same. Upon surrender to the
Trustee of the Book-Entry Certificates by the Book-Entry Custodian or the
Depository, as applicable, accompanied by registration instructions from the
Depository for registration of transfer, the Trustee shall issue the Definitive
Certificates. Such Definitive Certificates will be issued in minimum
denominations of $25,000 ($50,000 for the Class M-10 Certificates), except that
any beneficial ownership that was represented by a Book-Entry Certificate in an
amount less than $25,000 immediately prior to the issuance of a Definitive
Certificate shall be issued in a minimum denomination equal to the amount
represented by such Book-Entry Certificate. None of the Depositor, the Master
Servicer or the Trustee shall be liable for any delay in the delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of 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 the Definitive Certificates as Certificateholders hereunder.

                  SECTION 5.02. Registration of Transfer and Exchange of
                                Certificates.

                  (a) The Trustee shall cause to be kept at one of the offices
or agencies to be appointed by the Trustee in accordance with the provisions of
Section 8.12 a Certificate Register for the Certificates in which, subject 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. The Trustee will initially serve as Certificate Registrar
for the purpose of registering Certificates and transfers and exchanges of
Certificates as herein provided. The Certificate Registrar may appoint, by a
written instrument delivered to the Master Servicer and the Depositor, any other
bank or trust company to act as Certificate Registrar under such conditions as
the predecessor Certificate Registrar may prescribe, provided that the
predecessor Certificate Registrar shall not be relieved of any of its duties or
responsibilities hereunder by reason of such appointment. If the Trustee shall
at any time not be the Certificate Registrar, the Trustee shall have and
maintain the right to inspect the Certificate Register or to obtain a copy
thereof at all reasonable times, and to rely conclusively upon a certificate of
the Certificate Registrar as to the information set forth in the Certificate
Register.

                  (b) No transfer of any Class M-10, Class CE Certificate, Class
P Certificate or Residual Certificate shall be made unless that 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 a Class CE Certificate, Class P Certificate or
Residual Certificate is to be made without registration or qualification (other
than in connection with the initial transfer of any such Certificate by the
Depositor to an affiliate of the Depositor), the Trustee and the Certificate
Registrar shall each require receipt of: (i) if such transfer is purportedly
being made in reliance upon Rule 144A under the 1933 Act, written certifications
from the Certificateholder desiring to effect the transfer and from such
Certificateholder's prospective transferee, substantially in the forms attached
hereto as Exhibit F-1; and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration
(which Opinion of Counsel shall not be an expense of the Depositor, the Trustee,
the Master Servicer, in its capacity as such, or the Trust Fund), together with
copies of the written certification(s) of the Certificateholder desiring to
effect the transfer and/or such Certificateholder's prospective transferee upon
which such Opinion of Counsel is based, if any. None of the Depositor, the
Certificate Registrar or the Trustee is obligated to register or qualify the
Class M-10 Certificates, the Class CE Certificates, the Class P Certificates or
the Residual Certificates under the 1933 Act or any other securities laws or to
take any action not otherwise required under this Agreement to permit the
transfer of such Certificates without registration or qualification. Any
Certificateholder desiring to effect the transfer of a Class M-10 Certificate,
Class CE Certificate, Class P Certificate or Residual Certificate shall, and
does hereby agree to, indemnify the Trustee, the Depositor, the Certificate
Registrar and the Master Servicer 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.

                  Notwithstanding the foregoing, no certification or Opinion of
Counsel described in this Section 5.02(b) will be required in connection with
the transfer, on the Closing Date, of any

                                      119
<PAGE>

Class R Certificate by the Depositor to an "accredited investor" within the
meaning of Rule 501(d) of the 1933 Act.

                  (c) No transfer of a Class M-10 Certificate, Class CE
Certificate, Class P Certificate or Residual Certificate or any interest therein
shall be made to any Plan subject to ERISA or Section 4975 of the Code, any
Person acting, directly or indirectly, on behalf of any such Plan or any Person
acquiring such Certificates with "Plan Assets" of a Plan within the meaning of
the Department of Labor regulation promulgated at 29 C.F.R. ss. 2510.3-101
("Plan Assets"), as certified by such transferee in the form of Exhibit G,
unless either (i) the Trustee is provided with an Opinion of Counsel for the
benefit of the Depositor, the Trustee, the NIMS Insurer, the Certificate Insurer
and the Master Servicer and on which they may rely, which shall be to the effect
that the purchase and holding of such Certificates is permissible under
applicable law, will not constitute or result in any non-exempt prohibited
transaction under ERISA or Section 4975 of the Code and will not subject the
Depositor, the Master Servicer, the NIMS Insurer, the Certificate Insurer, the
Trustee or the Trust Fund to any obligation or liability (including obligations
or liabilities under ERISA or Section 4975 of the Code) in addition to those
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Depositor, the Master Servicer, the NIMS Insurer, the Certificate
Insurer, the Trustee or the Trust Fund or (ii) solely in the case of the Class
M-10 Certificates, the Trustee receives a certification from the prospective
transferee in the form of Exhibit G that the Class M-10 Certificates have been
offered in an underwriting or placement within the meaning of Prohibited
Transaction Exemption 2002-41, as amended ("PTE 2002-41"). Neither an Opinion of
Counsel nor any certification will be required in connection with the initial
transfer of any such Certificate by the Depositor to an affiliate of the
Depositor (in which case, the Depositor or any affiliate thereof shall have
deemed to have represented that such affiliate is not a Plan or a Person
investing Plan Assets) and the Trustee shall be entitled to conclusively rely
upon a representation (which, upon the request of the Trustee, shall be a
written representation) from the Depositor of the status of such transferee as
an affiliate of the Depositor.

                  Each beneficial owner of the Mezzanine Certificates 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 acting, directly or indirectly, on behalf of a Plan or with
Plan Assets, (ii) it has acquired and is holding such Mezzanine Certificates
(other than the Class M-10 Certificates) in reliance on the Underwriters'
Exemption, and that it understands that there are certain conditions to the
availability of the Underwriters' Exemption, including that the Certificates
(other than the Class M-10 Certificates) must be rated, at the time of purchase,
not lower than "BBB-" (or its equivalent) by Moody's, Fitch or S&P or (iii) for
Mezzanine Certificates other than the Class M- 10 Certificates (unless the
Trustee has received the certification referred to in clause (ii) of the
preceding paragraph in which case it shall apply to the Class M-10 Certificates)
(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 PTCE 95-60, and (3) the conditions in Sections I and
III of PTCE 95-60 have been satisfied.

                  If any Class M-10 Certificate, Class CE Certificate, Class P
Certificate, Residual Certificate or Mezzanine Certificate or any interest
therein is acquired or held in violation of the provisions of the preceding
paragraphs, the next preceding permitted beneficial owner will be treated as the
beneficial owner of that Certificate retroactive to the date of transfer to the
purported

                                      120
<PAGE>

beneficial owner. Any purported beneficial owner whose acquisition or holding of
any such Certificate or interest therein was effected in violation of the
provisions of the preceding paragraph shall indemnify and hold harmless the
Depositor, the Master Servicer, the Trustee, the NIMS Insurer, the Certificate
Insurer, and the Trust Fund from and against any and all liabilities, claims,
costs or expenses incurred by those parties as a result of that acquisition or
holding.

                  (d)(i) 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 to have irrevocably authorized the
         Certificate Registrar or its designee under clause (iii)(A) below to
         deliver payments to a Person other than such Person and to negotiate
         the terms of any mandatory sale under clause (iii)(B) below and to
         execute all instruments of Transfer and to do all other things
         necessary in connection with any such sale. The rights of each Person
         acquiring any Ownership Interest in a Residual Certificate are
         expressly subject to the following provisions:

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

                  (B) In connection with any proposed Transfer of any Ownership
         Interest in a Residual Certificate, the Certificate Registrar shall
         require delivery to it and shall not register the Transfer of any
         Residual Certificate until its receipt of an affidavit and agreement (a
         "Transfer Affidavit and Agreement"), in the form attached hereto as
         Exhibit F-2 from the proposed Transferee, in form and substance
         satisfactory to the Certificate Registrar, representing and warranting,
         among other things, that such Transferee is a Permitted Transferee,
         that it is not acquiring its Ownership Interest in the Residual
         Certificate that is the subject of the proposed Transfer as a nominee,
         trustee or agent for any Person that is not a Permitted Transferee,
         that for so long as it retains its Ownership Interest in a Residual
         Certificate, it will endeavor to remain a Permitted Transferee, and
         that it has reviewed the provisions of this Section 5.02(d) and agrees
         to be bound by them.

                  (C) Notwithstanding the delivery of a Transfer Affidavit and
         Agreement by a proposed Transferee under clause (B) above, if a
         Responsible Officer of the Certificate Registrar who is assigned to
         this transaction has actual knowledge that the proposed Transferee is
         not a Permitted Transferee, no Transfer of an Ownership Interest in a
         Residual Certificate to such proposed Transferee shall be effected.

                  (D) Each Person holding or acquiring any Ownership Interest in
         a Residual Certificate shall agree (x) to require a Transfer Affidavit
         and Agreement from any other Person to whom such Person attempts to
         transfer its Ownership Interest in a Residual Certificate and (y) not
         to transfer its Ownership Interest unless it provides a Transferor
         Affidavit (in the form attached hereto as Exhibit F-2), to the
         Certificate Registrar stating that, among other things, it has no
         actual knowledge that such other Person is not a Permitted Transferee.

                                      121
<PAGE>

                  (E) Each Person holding or acquiring an Ownership Interest in
         a Residual Certificate, by purchasing an Ownership Interest in such
         Certificate, agrees to give the Certificate Registrar written notice
         that it is a "pass-through interest holder" within the meaning of
         temporary Treasury regulation Section 1.67-3T(a)(2)(i)(A) immediately
         upon acquiring an Ownership Interest in a Residual Certificate, if it
         is, or is holding an Ownership Interest in a Residual Certificate on
         behalf of, a "pass-through interest holder."

                  (ii) The Certificate Registrar will register the Transfer of
         any Residual Certificate only if it shall have received the Transfer
         Affidavit and Agreement and all of such other documents as shall have
         been reasonably required by the Certificate Registrar as a condition to
         such registration. In addition, no Transfer of a Residual Certificate
         shall be made unless the Certificate Registrar shall have received a
         representation letter from the Transferee of such Certificate to the
         effect that such Transferee is a Permitted Transferee.

                  (iii)(A) If any purported Transferee shall become a Holder of
         a Residual Certificate in violation of the provisions of this Section
         5.02(d), then the last preceding Permitted Transferee shall be
         restored, to the extent permitted by law, to all rights as Holder
         thereof retroactive to the date of registration of such Transfer of
         such Residual Certificate. The Certificate Registrar shall be under no
         liability to any Person for any registration of Transfer of a Residual
         Certificate that is in fact not permitted by this Section 5.02(d) or
         for making any payments due on such Certificate to the Holder thereof
         or for taking any other action with respect to such Holder under the
         provisions of this Agreement.

                  (B) If any purported Transferee shall become a Holder of a
         Residual Certificate in violation of the restrictions in this Section
         5.02(d) and to the extent that the retroactive restoration of the
         rights of the Holder of such Residual Certificate as described in
         clause (iii)(A) above shall be invalid, illegal or unenforceable, then
         the Certificate Registrar shall have the right, without notice to the
         Holder or any prior Holder of such Residual Certificate, to sell such
         Residual Certificate to a purchaser selected by the Certificate
         Registrar on such terms as the Certificate Registrar may choose. Such
         purported Transferee shall promptly endorse and deliver each Residual
         Certificate in accordance with the instructions of the Certificate
         Registrar. Such purchaser may be the Certificate Registrar itself or
         any Affiliate of the Certificate Registrar. The proceeds of such sale,
         net of the commissions (which may include commissions payable to the
         Certificate Registrar or its Affiliates), expenses and taxes due, if
         any, will be remitted by the Certificate Registrar to such purported
         Transferee. The terms and conditions of any sale under this clause
         (iii)(B) shall be determined in the sole discretion of the Certificate
         Registrar, and the Certificate Registrar shall not be liable to any
         Person having an Ownership Interest in a Residual Certificate as a
         result of its exercise of such discretion.

                  (iv) The Trustee shall make available to the Internal Revenue
         Service and those Persons specified by the REMIC Provisions all
         information necessary to compute any tax imposed (A) as a result of the
         Transfer of an Ownership Interest in a Residual Certificate to any
         Person who is a Disqualified Organization, including the information
         described in Treasury regulations sections 1.860D-1(b)(5) and
         1.860E-2(a)(5) with respect to the "excess inclusions" of such Residual
         Certificate and (B) as a result of any regulated investment company,
         real estate investment trust,

                                      122
<PAGE>

common trust fund, partnership, trust, estate or organization described in
Section 1381 of the Code that holds an Ownership Interest in a Residual
Certificate having as among its record Holders at any time any Person which is a
Disqualified Organization. Reasonable compensation for providing such
information may be accepted by the Trustee.

                  (v) The provisions of this Section 5.02(d) set forth prior to
         this subsection (v) may be modified, added to or eliminated, provided
         that there shall have been delivered to the Trustee at the expense of
         the party seeking to modify, add to or eliminate any such provision the
         following:

                  (A) written notification from each Rating Agency to the effect
         that the modification, addition to or elimination of such provisions
         will not cause such Rating Agency to downgrade its then-current ratings
         of any Class of Certificates; and

                  (B) an Opinion of Counsel, in form and substance satisfactory
         to the Trustee, to the effect that such modification of, addition to or
         elimination of such provisions will not cause any Trust REMIC to cease
         to qualify as a REMIC and will not cause any Trust REMIC, as the case
         may be, to be subject to an entity-level tax caused by the Transfer of
         any Residual Certificate to a Person that is not a Permitted Transferee
         or (y) a Person other than the prospective transferee to be subject to
         a REMIC-tax caused by the Transfer of a Residual Certificate to a
         Person that is not a Permitted Transferee.

                  The Trustee shall forward to the NIMS Insurer and the
Certificate Insurer a copy of the items delivered to it pursuant to (A) and (B)
above.

                  (e) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Trustee maintained for such purpose pursuant to Section 8.12, the Trustee shall
execute and the Certificate Registrar shall authenticate and deliver, in the
name of the designated Transferee or Transferees, one or more new Certificates
of the same Class of a like aggregate Percentage Interest.

                  (f) At the option of the Holder thereof, any Certificate may
be exchanged for other Certificates of the same Class with authorized
denominations and a like aggregate Percentage Interest, upon surrender of such
Certificate to be exchanged at any office or agency of the Trustee maintained
for such purpose pursuant to Section 8.12. Whenever any Certificates are so
surrendered for exchange the Trustee, shall execute and cause the Certificate
Registrar to authenticate and deliver the Certificates which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange shall (if so required by the
Trustee) be duly endorsed by, or be accompanied by a written instrument of
transfer in the form satisfactory to the Trustee and the Certificate Registrar
duly executed by, the Holder thereof or his attorney duly authorized in writing.
In addition, with respect to each Residual Certificate, the Holder thereof may
exchange, in the manner described above, the Class R Certificate for three
separate Certificates, each representing such Holder's respective Percentage
Interest in the Class R-I Interest and the Class R-II Interest, respectively, in
each case that was evidenced by the Class R Certificate being exchanged.

                  (g) No service charge to the Certificateholders shall be made
for any transfer or exchange of Certificates, but the Trustee may require
payment of a sum sufficient to cover any tax

                                      123
<PAGE>

or governmental charge that may be imposed in connection with any transfer or
exchange of Certificates.

                  (h) All Certificates surrendered for transfer and exchange
shall be canceled and destroyed by the Certificate Registrar in accordance with
its customary procedures.

                  (i) The Trustee will cause the Certificate Registrar (unless
the Trustee is acting as Certificate Registrar) to provide notice to the Trustee
of each transfer of a Certificate and to provide the Trustee with an updated
copy of the Certificate Register on the first Business Day in March and August
of each year, commencing in March 2005.

                  (j) Any attempted or purported transfer of any Certificate in
violation of the provisions of Section 5.02(c) hereof shall be void AB INITIO
and such Certificate shall be considered to have been held continuously by the
prior permitted Holder.

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

                  If (i) any mutilated Certificate is surrendered to the Trustee
or the Certificate Registrar, or the Trustee and the Certificate Registrar
receive evidence to their satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee, the NIMS Insurer, the
Certificate Insurer and the Certificate Registrar such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
actual knowledge by the Trustee or the Certificate Registrar that such
Certificate has been acquired by a bona fide purchaser or the Trustee shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of the same Class and
of like denomination and Percentage Interest. Upon the issuance of any new
Certificate under this Section, 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
Certificate Registrar) connected therewith. Any replacement Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the applicable REMIC created hereunder, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

                  SECTION 5.04. Persons Deemed Owners.

                  The Depositor, the Master Servicer, the Trustee, the NIMS
Insurer, the Certificate Insurer, the Certificate Registrar and any agent of any
of them may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions pursuant to
Section 4.01 and for all other purposes whatsoever, and none of the Depositor,
the Master Servicer, the Trustee, the Certificate Registrar, the NIMS Insurer,
the Certificate Insurer or any agent of any of them shall be affected by notice
to the contrary.

                  SECTION 5.05. Certain Available Information.

                  On or prior to the date of the first sale of any Class CE
Certificate, Class P Certificate or Residual Certificate to an Independent third
party, the Depositor shall provide to the Trustee ten

                                      124
<PAGE>

copies of any private placement memorandum or other disclosure document used by
the Depositor in connection with the offer and sale of the Class CE
Certificates, Class P Certificates or Residual Certificates. In addition, if any
such private placement memorandum or disclosure document is revised, amended or
supplemented at any time following the delivery thereof to the Trustee, the
Depositor promptly shall inform the Trustee of such event and shall deliver to
the Trustee ten copies of the private placement memorandum or disclosure
document, as revised, amended or supplemented. The Trustee shall maintain at its
Corporate Trust Office and shall make available free of charge during normal
business hours for review by any Holder of a Certificate and/or Certificate
Owner or any Person identified to the Trustee as a prospective transferee of a
Certificate, originals or copies of the following items: (i) in the case of a
Holder, Certificate Owner or prospective transferee of a Class CE Certificate,
Class P Certificate or Residual Certificate, the private placement memorandum or
other disclosure document relating to such Certificates, if any, in the form
most recently provided to the Trustee; and (ii) in all cases, (A) this Agreement
and any amendments hereof entered into pursuant to Section 11.01, (B) all
monthly statements required to be delivered to Certificateholders of the
relevant Class pursuant to Section 4.02 since the Closing Date, and all other
notices, reports, statements and written communications delivered to the
Certificateholders of the relevant Class pursuant to this Agreement since the
Closing Date, (C) all certifications delivered by a Responsible Officer of the
Trustee since the Closing Date pursuant to Section 10.01(h), (D) any and all
Officers' Certificates delivered to the Trustee by the Master Servicer since the
Closing Date to evidence the Master Servicer's determination that any Advance or
Servicing Advance was, or if made, would be a Nonrecoverable Advance or
Nonrecoverable Servicing Advance, respectively, and (E) any and all Officers'
Certificates delivered to the Trustee by the Master Servicer since the Closing
Date pursuant to Section 4.04(a). Copies and mailing of any and all of the
foregoing items will be available from the Trustee upon request at the expense
of the person requesting the same.

                                   ARTICLE VI

                      THE DEPOSITOR AND THE MASTER SERVICER

                  SECTION 6.01. Liability of the Depositor and the Master
                                Servicer.

                  The Depositor and the Master Servicer each shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
by this Agreement and undertaken hereunder by the Depositor and the Master
Servicer herein.

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

                  Subject to the following paragraph, the Depositor will keep in
full effect its existence, rights and franchises as a corporation under the laws
of the jurisdiction of its incorporation. Subject to the following paragraph,
the Master Servicer will keep in full effect its existence, rights and
franchises as a corporation under the laws of the jurisdiction of its
incorporation and its qualification as an approved conventional seller/servicer
for Fannie Mae or Freddie Mac in good standing. The Depositor and the Master
Servicer each 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 respective duties
under this Agreement.

                  The Depositor or the Master Servicer may be merged or
consolidated with or into any Person, or transfer all or substantially all of
its assets to any Person, in which case any Person resulting from any merger or
consolidation to which the Depositor or the Master Servicer shall be a party, or
any Person succeeding to the business of the Depositor or the Master Servicer,
shall be the successor of the Depositor or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Master Servicer shall be qualified to service mortgage loans on behalf of
Fannie Mae or Freddie Mac; and provided further that the Rating Agencies'
ratings of the Class A Certificates (without regard to the Policy) and the
Mezzanine Certificates in effect immediately prior to such merger or
consolidation will not be qualified, reduced or withdrawn as a result thereof
(as evidenced by a letter to such effect from the Rating Agencies).

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

                  None of the Depositor, the NIMS Insurer, the Master Servicer
or any of the directors, officers, employees or agents of the Depositor or the
Master Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositor, the NIMS
Insurer, the Master Servicer or any such person against any breach of
warranties, representations or covenants made herein, or against any specific
liability imposed on the Master Servicer pursuant hereto, or against any
liability which

                                      126
<PAGE>

would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder. The Depositor, the NIMS Insurer, the Master
Servicer or the Trustee and any director, officer, employee or agent of the
Depositor, the NIMS Insurer, the Master Servicer or the Trustee may rely in good
faith on any document of any kind which, PRIMA FACIE, is properly executed and
submitted by any Person respecting any matters arising hereunder.

                  The Depositor, the NIMS Insurer, the Master Servicer and any
director, officer, employee or agent of the Depositor, the NIMS Insurer, or the
Master Servicer shall be indemnified and held harmless by the Trust Fund against
any loss, liability or expense incurred in connection with any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense relating to any specific Mortgage Loan or Mortgage Loans (except as
any such loss, liability or expense shall be otherwise reimbursable pursuant to
this Agreement) or, in the case of the Depositor and the Master Servicer, any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. Neither the Depositor, the NIMS
Insurer nor the Master Servicer shall be under any obligation to appear in,
prosecute or defend any legal action unless such action is related to its
respective duties under this Agreement and, in its opinion, does not involve it
in any expense or liability; provided, however, that each of the Depositor, the
NIMS Insurer and the Master Servicer 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, unless the Depositor or the Master
Servicer acts without the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights (which consent shall not be necessary in the case
of litigation or other legal action by either to enforce their respective rights
or defend themselves hereunder), the legal expenses and costs of such action and
any liability resulting therefrom (except any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder) shall be expenses, costs and liabilities of
the Trust Fund, and the Depositor, the NIMS Insurer and the Master Servicer
shall be entitled to be reimbursed therefor from the Collection Account as and
to the extent provided in Section 3.05, any such right of reimbursement being
prior to the rights of the Certificateholders to receive any amount in the
Collection Account.

                  SECTION 6.04. Limitation on Resignation of the Master
                                Servicer.

                  The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (i) upon determination that its duties
hereunder are no longer permissible under applicable law or (ii) with the
written consent of the Trustee, the NIMS Insurer, the Certificate Insurer and
written confirmation from each Rating Agency (which confirmation shall be
furnished to the Depositor, the NIMS Insurer, the Certificate Insurer and the
Trustee) that such resignation will not cause such Rating Agency to reduce the
then current rating of the Class A Certificates (without regard to the Policy)
or the Mezzanine Certificates. Any such determination pursuant to clause (i) of
the preceding sentence, permitting the resignation of the Master Servicer, shall
be evidenced by an Opinion of Counsel to such effect obtained at the expense of
the Master Servicer and delivered to the Trustee, the Certificate Insurer and
the NIMS Insurer. No resignation of the Master Servicer shall become effective
until the Trustee or a successor servicer acceptable to the NIMS Insurer and

                                      127
<PAGE>

the Certificate Insurer shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement.

                  Except as expressly provided herein, the Master Servicer shall
not assign or transfer any of its rights, benefits or privileges hereunder to
any other Person, nor delegate to or subcontract with, nor authorize or appoint
any other Person to perform any of the duties, covenants or obligations to be
performed by the Master Servicer hereunder. If, pursuant to any provision
hereof, the duties of the Master Servicer are transferred to a successor master
servicer, the entire amount of the Servicing Fee and other compensation payable
to the Master Servicer pursuant hereto shall thereafter be payable to such
successor master servicer.

                  SECTION 6.05. Rights of the Depositor in Respect of the Master
                                Servicer.

                  The Master Servicer shall afford (and any Sub-Servicing
Agreement shall provide that each Sub-Servicer shall afford) the Depositor, the
NIMS Insurer and the Trustee, upon reasonable notice, during normal business
hours, access to all records maintained by the Master Servicer (and any such
Sub-Servicer) in respect of the Master Servicer's rights and obligations
hereunder and access to officers of the Master Servicer (and those of any such
Sub-Servicer) responsible for such obligations. Upon request, the Master
Servicer shall furnish to the Depositor, the NIMS Insurer and the Trustee its
(and any such Sub-Servicer's) most recent financial statements and such other
information relating to the Master Servicer's capacity to perform its
obligations under this Agreement that it possesses. To the extent such
information is not otherwise available to the public, the Depositor, the NIMS
Insurer and the Trustee shall not disseminate any information obtained pursuant
to the preceding two sentences without the Master Servicer's (or any such
Sub-Servicer's) written consent, except as required pursuant to this Agreement
or to the extent that it is appropriate to do so (i) in working with legal
counsel, auditors, taxing authorities or other governmental agencies, rating
agencies or reinsurers or (ii) pursuant to any law, rule, regulation, order,
judgment, writ, injunction or decree of any court or governmental authority
having jurisdiction over the Depositor, the Trustee or the Trust Fund, and in
either case, the Depositor, the NIMS Insurer or the Trustee, as the case may be,
shall use its best efforts to assure the confidentiality of any such
disseminated non-public information. The Depositor may, but is not obligated to,
enforce the obligations of the Master Servicer under this Agreement and may, but
is not obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer under this Agreement or exercise the rights of
the Master Servicer under this Agreement; provided that the Master Servicer
shall not be relieved of any of its obligations under this Agreement by virtue
of such performance by the Depositor or its designee. The Depositor shall not
have any responsibility or liability for any action or failure to act by the
Master Servicer and is not obligated to supervise the performance of the Master
Servicer under this Agreement or otherwise.

                  SECTION 6.06. Sub-Servicing Agreements Between the Master
                                Servicer and Sub-Servicers.

                  (a) The Master Servicer may enter into Sub-Servicing
Agreements (provided that such agreements would not result in a withdrawal or a
downgrade by any Rating Agency of the ratings on any Class of Certificates
(without regard to the Policy) and the NIMS Insurer shall have consented to such
Sub-Servicing Agreement) with Sub-Servicers, for the servicing and
administration of the Mortgage Loans.

                  Each Sub-Servicer shall be (i) authorized to transact business
in the state or states in which the related Mortgaged Properties it is to
service are situated, if and to the extent required by applicable law to enable
the Sub-Servicer to perform its obligations hereunder and under the Sub-
Servicing Agreement, (ii) an institution approved as a mortgage loan originator
by the Federal Housing Administration or an institution the deposit accounts in
which are insured by the FDIC and (iii) a Freddie Mac or Fannie Mae approved
mortgage servicer. Each Sub-Servicing Agreement must impose on the Sub-Servicer
requirements conforming to the provisions set forth in Section 6.11 and provide
for servicing of the Mortgage Loans consistent with the terms of this Agreement.
The Master Servicer will examine each Sub-Servicing Agreement and will be
familiar with the terms thereof. The terms of any Sub-Servicing Agreement will
not be inconsistent with any of the provisions of this Agreement. The Master
Servicer and the Sub-Servicers may enter into and make amendments to the
Sub-Servicing Agreements or enter into different forms of Sub-Servicing
Agreements; provided, however, that any such amendments or different forms shall
be consistent with and not violate the provisions of this Agreement, and that no
such amendment or different form shall be made or entered into which could be
reasonably expected to be materially adverse to the interests of the
Certificateholders, without the consent of the Holders of Certificates entitled
to at least 66% of the Voting Rights. Any variation without the consent of the
Holders of Certificates entitled to at least 66% of the Voting Rights from the
provisions set forth in Section 6.11, provisions relating to insurance in
Section 3.10 or priority requirements of Sub-Servicing Accounts, or credits and
charges to the Sub-Servicing Accounts or the timing and amount of remittances by
the Sub- Servicers to the Master Servicer, are conclusively deemed to be
inconsistent with this Agreement and therefore prohibited. The Master Servicer
shall deliver to the Trustee, the Certificate Insurer and the NIMS Insurer
copies of all Sub-Servicing Agreements, and any amendments or modifications
thereof, promptly upon the Master Servicer's execution and delivery of such
instruments.

                  (b) As part of its servicing activities hereunder, the Master
Servicer (except as otherwise provided in the last sentence of this paragraph),
for the benefit of the Trustee, the Certificate Insurer and the
Certificateholders, shall enforce the obligations of each Sub-Servicer under the
related Sub-Servicing Agreement and of the Seller under the Mortgage Loan
Purchase Agreement, including, without limitation, any obligation to make
advances in respect of delinquent payments as required by a Sub-Servicing
Agreement, or to purchase a Mortgage Loan on account of missing or defective
documentation or on account of a breach of a representation, warranty or
covenant, as described in Section 2.03(a). Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Sub-Servicing
Agreements, and the pursuit of other appropriate remedies, shall be in such form
and carried out to such an extent and at such time as the Master Servicer, in
its good faith business judgment, would require were it the owner of the related
Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at
its own expense,

                                      129
<PAGE>

and shall be reimbursed therefor only (i) from a general recovery resulting from
such enforcement, to the extent, if any, that such recovery exceeds all amounts
due in respect of the related Mortgage Loans or (ii) from a specific recovery of
costs, expenses or attorneys' fees against the party against whom such
enforcement is directed. Enforcement of the Mortgage Loan Purchase Agreement
against the Seller shall be effected by the Master Servicer to the extent it is
not the Seller, and otherwise by the Trustee, in accordance with the foregoing
provisions of this paragraph.

                  SECTION 6.07. Successor Sub-Servicers.

                  The Master Servicer, with the consent of the NIMS Insurer,
shall be entitled to terminate any Sub-Servicing Agreement and the rights and
obligations of any Sub-Servicer pursuant to any Sub-Servicing Agreement in
accordance with the terms and conditions of such Sub-Servicing Agreement. In the
event of termination of any Sub-Servicer, all servicing obligations of such Sub-
Servicer shall be assumed simultaneously by the Master Servicer without any act
or deed on the part of such Sub-Servicer or the Master Servicer, and the Master
Servicer either shall service directly the related Mortgage Loans or shall enter
into a Sub-Servicing Agreement with a successor Sub-Servicer which qualifies
under Section 6.06.

                  Any Sub-Servicing Agreement shall include the provision that
such agreement may be immediately terminated by the Trustee without fee, in
accordance with the terms of this Agreement, in the event that the Master
Servicer shall, for any reason, no longer be the Master Servicer (including
termination due to a Master Servicer Event of Default).

                  SECTION 6.08. Liability of the Master Servicer.

                  Notwithstanding any Sub-Servicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Master Servicer and a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall remain obligated and
primarily liable to the Trustee and the Certificateholders for the servicing and
administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
Sub-Servicing Agreements or arrangements or by virtue of indemnification from
the Sub-Servicer and to the same extent and under the same terms and conditions
as if the Master Servicer alone were servicing and administering the Mortgage
Loans. The Master Servicer shall be entitled to enter into any agreement with a
Sub- Servicer for indemnification of the Master Servicer by such Sub-Servicer
and nothing contained in this Agreement shall be deemed to limit or modify such
indemnification.

                  SECTION 6.09. No Contractual Relationship Between
                                Sub-Servicers and the NIMS Insurer, the
                                Certificate Insurer, the Trustee or
                                Certificateholders.

                  Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Master Servicer alone, and the NIMS Insurer, the Certificate Insurer, the
Trustee and Certificateholders shall not be deemed parties thereto and shall
have no claims, rights, obligations, duties or liabilities with respect to the
Sub-Servicer except as set

                                      130
<PAGE>

forth in Section 6.10. The Master Servicer shall be solely liable for all fees
owed by it to any Sub- Servicer, irrespective of whether the Master Servicer's
compensation pursuant to this Agreement is sufficient to pay such fees.

                  SECTION 6.10. Assumption or Termination of Sub-Servicing
                                Agreements by Trustee.

                  In the event the Master Servicer shall for any reason no
longer be the master servicer (including termination due to a Master Servicer
Event of Default), the Trustee or its designee shall thereupon assume (or cause
its designee or the successor master servicer for the Trustee appointed pursuant
to Section 7.02 to assume) all of the rights and obligations of the Master
Servicer under each Sub-Servicing Agreement that the Master Servicer may have
entered into, unless the Trustee elects to terminate any Sub-Servicing Agreement
in accordance with its terms as provided in Section 6.07. Upon such assumption,
the Trustee, its designee or the successor servicer for the Trustee appointed
pursuant to Section 7.02 shall be deemed, subject to Section 6.07, to have
assumed all of the Master Servicer's interest therein and to have replaced the
Master Servicer as a party to each Sub-Servicing Agreement to the same extent as
if each Sub-Servicing Agreement had been assigned to the assuming party, except
that (i) the Master Servicer shall not thereby be relieved of any liability or
obligations under any Sub-Servicing Agreement and (ii) none of the Trustee, its
designee or any successor Master Servicer shall be deemed to have assumed any
liability or obligation of the Master Servicer that arose before it ceased to be
the Master Servicer.

                  The Master Servicer at its expense shall, upon request of the
Trustee, deliver to the assuming party all documents and records relating to
each Sub-Servicing Agreement and the Mortgage Loans then being serviced and an
accounting of amounts collected and held by or on behalf of it, and otherwise
use its best efforts to effect the orderly and efficient transfer of the Sub-
Servicing Agreements to the assuming party.

                  SECTION 6.11. Sub-Servicing Accounts.

                  In those cases where a Sub-Servicer is servicing a Mortgage
Loan pursuant to a Sub- Servicing Agreement, the Sub-Servicer will be required
to establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be an Eligible Account. The
Sub-Servicer shall deposit in the clearing account (which account must be an
Eligible Account) in which it customarily deposits payments and collections 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 Sub-Servicer's
receipt thereof, all proceeds of Mortgage Loans received by the Sub-Servicer
less its servicing compensation to the extent permitted by the Sub-Servicing
Agreement, and shall thereafter deposit such amounts in the Sub-Servicing
Account, in no event more than two Business Days after the deposit of such funds
into the clearing account. The Sub- Servicer shall thereafter deposit such
proceeds in the Collection Account or remit such proceeds to the Master Servicer
for deposit in the Collection Account not later than two Business Days after the
deposit of such amounts in the Sub-Servicing Account. For purposes of this
Agreement, the Master Servicer shall be deemed to have received payments on the
Mortgage Loans when the Sub-Servicer receives such payments.

                                     DEFAULT

                  SECTION 7.01. Master Servicer Events of Default.

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

                  (i) any failure by the Master Servicer to remit to the Trustee
         for distribution to the Certificateholders any payment (other than an
         Advance required to be made from its own funds on any Master Servicer
         Remittance Date pursuant to Section 4.03) required to be made under the
         terms of the Certificates and this Agreement which continues unremedied
         for a period of one Business Day after the date upon which written
         notice of such failure, requiring the same to be remedied, shall have
         been given to the Master Servicer by the Depositor or the Trustee (in
         which case notice shall be provided by telecopy), or to the Master
         Servicer, the Depositor and the Trustee by the NIMS Insurer or the
         Holders of Certificates entitled to at least 25% of the Voting Rights;
         or

                  (ii) any failure on the part of the Master Servicer duly to
         observe or perform in any material respect any of the covenants or
         agreements on the part of the Master Servicer contained in the
         Certificates or in this Agreement (or, if the Master Servicer is the
         Seller, the failure of the Seller to repurchase a Mortgage Loan as to
         which a breach has been established that requires a repurchase pursuant
         to the terms of Section 7 of the Mortgage Loan Purchase Agreement)
         which continues unremedied for a period of 45 days after the earlier of
         (i) the date on which written notice of such failure, requiring the
         same to be remedied, shall have been given to the Master Servicer by
         the Depositor or the Trustee, or to the Master Servicer, the Depositor
         and the Trustee by the NIMS Insurer or the Holders of Certificates
         entitled to at least 25% of the Voting Rights and (ii) actual knowledge
         of such failure by a Servicing Officer of the Master Servicer; or

                  (iii) a decree or order of a court or agency or supervisory
         authority having jurisdiction in the premises in an involuntary case
         under any present or future federal or state bankruptcy, insolvency or
         similar law or the appointment of a conservator or receiver or
         liquidator in any insolvency, readjustment of debt, marshaling of
         assets and liabilities or similar proceeding, or for the winding-up or
         liquidation of its affairs, shall have been entered against the Master
         Servicer and if such proceeding is being contested by the Master
         Servicer in good faith, such decree or order shall have remained in
         force undischarged or unstayed for a period of 60 days or results in
         the entry of an order for relief or any such adjudication or
         appointment; or

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

                                      132
<PAGE>

                  (v) the Master 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) any failure by the Master Servicer of the Master Servicer
         Termination Test; or

                  (vii) any failure of the Master Servicer to make any Advance
         on any Master Servicer Remittance Date required to be made from its own
         funds pursuant to Section 4.03 which continues unremedied until 3:00
         p.m. New York time on the Business Day immediately following the Master
         Servicer Remittance Date.

                  If a Master Servicer Event of Default described in clauses (i)
through (vi) of this Section shall occur, then, and in each and every such case,
so long as such Master Servicer Event of Default shall not have been remedied,
the Depositor, the NIMS Insurer or the Trustee may, and shall at the written
direction of the Holders of Certificates entitled to at least 51% of Voting
Rights, or at the direction of the NIMS Insurer, the Trustee shall, by notice in
writing to the Master Servicer and the Depositor, terminate all of the rights
and obligations of the Master Servicer in its capacity as Master Servicer under
this Agreement, to the extent permitted by law, and in and to the Mortgage Loans
and the proceeds thereof. If a Master Servicer Event of Default described in
clause (vii) hereof shall occur, the Trustee shall, by notice in writing to the
Master Servicer and the Depositor, terminate all of the rights and obligations
of the Master Servicer in its capacity as Master Servicer under this Agreement
and in and to the Mortgage Loans and the proceeds thereof and the Trustee as
successor Master Servicer or a successor Master Servicer appointed in accordance
with Section 7.02, shall immediately make such Advance(which Advance shall be
part of Available Funds for such Distribution Date) and assume, pursuant to
Section 7.02, the duties of a successor Master Servicer. On or after the receipt
by the Master Servicer of such written notice, all authority and power of the
Master Servicer under this Agreement, whether with respect to the Certificates
(other than as a Holder of any Certificate) or the Mortgage Loans or otherwise,
shall pass to and be vested in the Trustee pursuant to and under this Section
and, without limitation, the Trustee is hereby authorized and empowered, as
attorney-in-fact or otherwise, to execute and deliver on behalf of and at the
expense of the Master Servicer, any and all documents and other instruments and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. The Master Servicer agrees, at its sole cost and expense, promptly
(and in any event no later than ten Business Days subsequent to such notice) to
provide the Trustee with all documents and records requested by it to enable it
to assume the Master Servicer's functions under this Agreement, and to cooperate
with the Trustee in effecting the termination of the Master Servicer's
responsibilities and rights under this Agreement, including, without limitation,
the transfer within one Business Day to the Trustee for administration by it of
all cash amounts which at the time shall be or should have been credited by the
Master Servicer to the Collection Account held by or on behalf of the Master
Servicer, the Distribution Account or any REO Account or Servicing Account held
by or on behalf of the Master Servicer or thereafter be received with respect to
the Mortgage Loans or any REO Property serviced by the Master Servicer
(provided, however, that the Master 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 or

                                      133
<PAGE>

otherwise, and shall continue to be entitled to the benefits of Section 6.03,
notwithstanding any such termination, with respect to events occurring prior to
such termination). For purposes of this Section 7.01, the Trustee shall not be
deemed to have knowledge of a Master Servicer Event of Default unless a
Responsible Officer of the Trustee assigned to and working in the Trustee's
Corporate Trust Office has actual knowledge thereof or unless written notice is
received by the Trustee of any such event and such notice references the
Certificates, REMIC I or this Agreement.

                  The Trustee shall be entitled to be reimbursed by the Master
Servicer (or by the Trust Fund if the Master Servicer is unable to fulfill its
obligations hereunder) for all costs associated with the transfer of servicing
from the predecessor servicer, including without limitation, any costs or
expenses associated with the complete transfer of all servicing data and the
completion, correction or manipulation of such servicing data as may be required
by the Trustee to correct any errors or insufficiencies in the servicing data or
otherwise to enable the Trustee to service the Mortgage Loans properly and
effectively.

                  SECTION 7.02. Trustee to Act; Appointment of Successor.

                  (a) On and after the time the Master Servicer receives a
notice of termination, the Trustee shall be the successor in all respects to the
Master Servicer in its capacity as Master Servicer under this Agreement and the
transactions set forth or provided for herein and shall be subject to all the
responsibilities, duties and liabilities relating thereto and arising thereafter
placed on the Master Servicer (except for any representations or warranties of
the Master Servicer under this Agreement, the responsibilities, duties and
liabilities contained in Section 2.03(c) and its obligation to deposit amounts
in respect of losses pursuant to Section 3.06) by the terms and provisions
hereof including, without limitation, the Master Servicer's obligations to make
Advances pursuant to Section 4.03; provided, however, that if the Trustee is
prohibited by law or regulation from obligating itself to make advances
regarding delinquent mortgage loans, then the Trustee shall not be obligated to
make Advances pursuant to Section 4.03; and provided further, that any failure
to perform such duties or responsibilities caused by the Master Servicer's
failure to provide information required by Section 7.01 shall not be considered
a default by the Trustee as successor to the Master Servicer hereunder;
provided, however, it is understood and acknowledged by the parties that there
will be a period of transition (not to exceed 90 days) before the servicing
transfer is fully effected. As compensation therefor, effective from and after
the time the Master Servicer receives a notice of termination or immediately
upon assumption of the obligations to make Advances, the Trustee shall be
entitled to the Servicing Fee and all funds relating to the Mortgage Loans to
which the Master Servicer would have been entitled if it had continued to act
hereunder (other than amounts which were due or would become due to the Master
Servicer prior to its termination or resignation). Notwithstanding the above and
subject to the next paragraph, the Trustee may, if it shall be unwilling to so
act, or shall, if it is unable to so act or if it is prohibited by law from
making advances regarding delinquent mortgage loans, or if the Holders of
Certificates entitled to at least 51% of the Voting Rights or the NIMS Insurer
so request in writing to the Trustee promptly appoint or petition a court of
competent jurisdiction to appoint, an established mortgage loan servicing
institution acceptable to each Rating Agency (with confirmation from the Rating
Agencies that such appointment shall not result in the reduction or withdrawal
of the rating of any outstanding Class of Certificates (without regard to the
Policy)) and acceptable to the NIMS Insurer and having a net worth of not less
than $15,000,000 as the successor to the Master Servicer under this Agreement in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Master Servicer under this Agreement. No appointment

                                      134

of a successor to the Master Servicer under this Agreement shall be effective
until the assumption by the successor of all of the Master Servicer's
responsibilities, duties and liabilities hereunder. In connection with such
appointment and assumption described herein, the Trustee may make such
arrangements for the compensation of such successor out of payments on Mortgage
Loans as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of that permitted the Master Servicer as such
hereunder. The Depositor, the Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Pending appointment of a successor to the Master Servicer under this
Agreement, the Trustee shall act in such capacity as hereinabove provided.

                  Upon removal or resignation of the Master Servicer, the
Trustee, with the cooperation of the Depositor, (x) shall solicit bids for a
successor Master Servicer as described below and (y) pending the appointment of
a successor Master Servicer as a result of soliciting such bids, shall serve as
Master Servicer of the Mortgage Loans serviced by such predecessor Master
Servicer. The Trustee shall solicit, by public announcement, bids from housing
and home finance institutions, banks and mortgage servicing institutions meeting
the qualifications set forth above (including the Trustee or any affiliate
thereof) (including that such mortgage loan servicing institution will be
acceptable to each Rating Agency and the NIMS Insurer). Such public announcement
shall specify that the successor Master Servicer shall be entitled to the
servicing compensation agreed upon between the Trustee, the successor Master
Servicer and the Depositor; provided, however, that no such fee shall exceed the
Servicing Fee. Within thirty days after any such public announcement, the
Trustee, with the cooperation of the Depositor, shall negotiate in good faith
and effect the sale, transfer and assignment of the servicing rights and
responsibilities hereunder to the qualified party submitting the highest
satisfactory bid as to the price they will pay to obtain such servicing. The
Trustee upon receipt of the purchase price shall pay such purchase price to the
Master Servicer being so removed, after deducting from any sum received by the
Trustee from the successor to the Master Servicer in respect of such sale,
transfer and assignment all costs and expenses of any public announcement and of
any sale, transfer and assignment of the servicing rights and responsibilities
reasonably incurred hereunder. After such deductions, the remainder of such sum
shall be paid by the Trustee to the Master Servicer at the time of such sale.

                  (b) If the Master Servicer fails to remit to the Trustee for
distribution to the Certificateholders any payment required to be made under the
terms of the Certificates and this Agreement (for purposes of this Section
7.02(b), a "Remittance") because the Master Servicer is the subject of a
proceeding under the federal Bankruptcy Code and the making of such Remittance
is prohibited by Section 362 of the federal Bankruptcy Code, the Trustee shall
upon notice of such prohibition, regardless of whether it has received a notice
of termination under Section 7.01, advance the amount of such Remittance by
depositing such amount in the Distribution Account on the related Distribution
Date. The Trustee shall be obligated to make such advance only if (i) such
advance, in the good faith judgment of the Trustee can reasonably be expected to
be ultimately recoverable from Stayed Funds and (ii) the Trustee is not
prohibited by law from making such advance or obligating itself to do so. Upon
remittance of the Stayed Funds to the Trustee or the deposit thereof in the
Distribution Account by the Master Servicer, a trustee in bankruptcy or a
federal bankruptcy court, the Trustee may recover the amount so advanced,
without interest, by withdrawing such amount from the Distribution Account;
however, nothing in this Agreement shall be deemed to affect the Trustee's
rights to recover from the Master Servicer's own funds interest on the amount of
any such advance. If the Trustee at any time makes an advance under this
Subsection which it later

                                      135
<PAGE>

determines in its good faith judgment will not be ultimately recoverable from
the Stayed Funds with respect to which such advance was made, the Trustee shall
be entitled to reimburse itself for such advance, without interest, by
withdrawing from the Distribution Account, out of amounts on deposit therein, an
amount equal to the portion of such advance attributable to the Stayed Funds.

                  (c) If the Master Servicer is terminated pursuant to Section
7.01, then the successor Master Servicer shall not be permitted to reimburse
itself directly for Advances or Servicing Advances under Section 3.05(a)(ii),
Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii) if the Master
Servicer has not been fully reimbursed for its Advances and Servicing Advances,
but instead the successor Master Servicer shall include such amounts in the
applicable remittance to the Trustee made pursuant to Section 3.04(g) to the
extent of amounts on deposit in the Collection Account on the related Master
Servicer Remittance Date. The Trustee is hereby authorized to pay to the
terminated Master Servicer (or the related Advancing Person in accordance with
Section 3.23) and the successor Master Servicer, as applicable, reimbursements
for Advances and Servicing Advances from the Distribution Account to the same
extent each such Master Servicer would have been permitted to reimburse itself
for such Advances and/or Servicing Advances in accordance with Section
3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii),
as the case may be. All Advances and Servicing Advances made pursuant to the
terms of this Agreement shall be deemed made and shall be reimbursed on a "first
in-first out" (FIFO) basis. At such time as the Master Servicer (or related
Advancing Person) has been reimbursed for all Advances and Servicing Advances
made by it, the successor Master Servicer shall no longer be required to remit
in accordance with the first sentence of this Section 7.02(c) and shall then be
permitted to reimburse itself directly for Advances and Servicing Advances in
accordance with Section 3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or
Section 3.05(a)(vii).

                  SECTION 7.03. Notification to Certificateholders.

                  (a) Upon any termination of the Master Servicer pursuant to
Section 7.01 above or any appointment of a successor to the Master Servicer
pursuant to Section 7.02 above, the Trustee shall give prompt written notice
thereof to Certificateholders, the Certificate Insurer and the NIMS Insurer at
their respective addresses appearing in the Certificate Register.

                  (b) Not later than the later of 60 days after the occurrence
of any event, which constitutes or which, with notice or lapse of time or both,
would constitute a Master Servicer Event of Default or five days after a
Responsible Officer of the Trustee becomes aware of the occurrence of such an
event, the Trustee shall transmit by mail to the NIMS Insurer, the Certificate
Insurer and to all Holders of Certificates notice of each such occurrence,
unless such default or Master Servicer Event of Default shall have been cured or
waived.

                  SECTION 7.04. Waiver of Master Servicer Events of Default.

                  The Holders representing at least 66% of the Voting Rights
(with the consent of the NIMS Insurer) evidenced by all Classes of Certificates
affected by any default or Master Servicer Event of Default hereunder may waive
such default or Master Servicer Event of Default; PROVIDED, HOWEVER, that a
default or Master Servicer Event of Default under clause (i) or (vii) of Section
7.01 may be waived only by all of the Holders of the Regular Certificates (with
the consent of the NIMS Insurer). Upon any such waiver of a default or Master
Servicer Event of Default, such default or

                                      136
<PAGE>

Master Servicer Event of Default shall cease to exist and shall be deemed to
have been remedied for every purpose hereunder. No such waiver shall extend to
any subsequent or other default or Master Servicer Event of Default or impair
any right consequent thereon except to the extent expressly so waived.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

                  SECTION 8.01. Duties of Trustee.

                  The Trustee, prior to the occurrence of a Master Servicer
Event of Default and after the curing of all Master Servicer Events of Default
which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Agreement. During a Master Servicer Event
of Default, the Trustee shall exercise such of the rights and powers vested in
it by this Agreement, and use the same degree of care and skill in their
exercise as a prudent person would exercise or use under the circumstances in
the conduct of such person's own affairs. Any permissive right of the Trustee
enumerated in this Agreement shall not be construed as a duty.

                  The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform on their face to the requirements of this Agreement. If any such
instrument is found not to conform on its face to the requirements of this
Agreement in a material manner, the Trustee shall take such action as it deems
appropriate to have the instrument corrected, and if the instrument is not
corrected to its respective satisfaction, such dissatisfied party will provide
notice thereof to the Certificateholders, the Certificate Insurer and the NIMS
Insurer.

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

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

                  (ii) The Trustee shall not be personally liable 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; and

                  (iii) The Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the direction of the NIMS Insurer or the
         Holders of Certificates entitled to at least 25% of the Voting Rights
         relating to the time, method and place of conducting any proceeding for
         any remedy available to the Trustee or exercising any trust or power
         conferred upon it, under this Agreement.

                                      138
<PAGE>

                  The Trustee shall not be required to expend or risk its own
funds or otherwise incur financial liability 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 it
to perform, or be responsible for the manner of performance of, any of the
obligations of the Master Servicer under this Agreement, except during such
time, if any, as the Trustee shall be the successor to, and be vested with the
rights, duties, powers and privileges of, the Master Servicer in accordance with
the terms of this Agreement.

                  SECTION 8.02. Certain Matters Affecting the Trustee.

                  (a) Except as otherwise provided in Section 8.01:

                  (i) The Trustee may request and rely upon and shall be
         protected in acting or refraining from acting upon any resolution,
         Officers' Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document reasonably
         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 Opinion of
         Counsel shall be full and complete authorization and protection in
         respect of any action taken or suffered or omitted by it hereunder in
         good faith and in accordance with such Opinion of Counsel;

                  (iii) The Trustee shall not be under any obligation to
         exercise any of the trusts or powers vested in it by 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 or the NIMS Insurer, pursuant to the provisions of
         this Agreement, unless such Certificateholders or the NIMS Insurer, as
         applicable, shall have offered to the Trustee security or indemnity
         reasonably 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 Master Servicer Event of Default (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 or use under the
         circumstances in the conduct of such person's own affairs;

                  (iv) The Trustee shall not be personally liable 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) Prior to the occurrence of a Master Servicer Event of
         Default hereunder and after the curing of all Master Servicer Events of
         Default which may have occurred, the Trustee shall not be bound to make
         any investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, approval, bond or other paper or document, unless
         requested in writing to do so by the NIMS Insurer or the Holders of
         Certificates entitled to at least 25% of the Voting Rights; provided,
         however, that if the payment within a reasonable time to the Trustee of
         the costs, expenses

                                      139
<PAGE>

         or liabilities likely to be incurred by it in the making of such
         investigation is, in the opinion of the Trustee not reasonably assured
         to the Trustee by such Certificateholders, the Trustee may require
         reasonable indemnity against such expense, or liability from such
         Certificateholders or the NIMS Insurer as a condition to taking any
         such action;

                  (vi) The Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys; and

                  (vii) The Trustee shall not be personally liable for any loss
         resulting from the investment of funds held in the Collection Account,
         the Escrow Account or the REO Account made at the direction of the
         Master Servicer pursuant to Section 3.06.

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

                  (c) The Depositor hereby directs the Trustee to execute,
         deliver and perform its obligations under the Cap Contracts on the
         Closing Date and thereafter on behalf of the Holders of the Class A-1
         Certificates, the Group II Certificates and the Mezzanine Certificates.
         The Seller, the Depositor, the Master Servicer and the Holders of the
         Class A-1 Certificates, the Group II Certificates and the Mezzanine
         Certificates by their acceptance of such Certificates, acknowledge and
         agree that the Trustee shall execute, deliver and perform its
         obligations under the Cap Contracts and shall do so solely in its
         capacity as Trustee of the Trust Fund and not in its individual
         capacity.

                  (d) The Depositor hereby directs the Trustee to execute and
         deliver the PMI Policy on behalf of the Trust Fund in the form
         presented to it by the Depositor and approved by the Certificate
         Insurer. Every provision of this Agreement relating to the conduct or
         affecting the liability of or affording protection to the Trustee shall
         apply to the Trustee's execution of the PMI Policy, and the performance
         of its duties and satisfaction of its obligations thereunder.

                  SECTION 8.03. The Trustee Not Liable for Certificates or
                                Mortgage Loans.

                  The recitals contained herein and in the Certificates (other
than the signature of the Trustee, the authentication of the Certificate
Registrar on the Certificates, the acknowledgments of the Trustee contained in
Article II and the representations and warranties of the Trustee in Section
8.13) shall be taken as the statements of the Depositor and the Trustee assumes
no responsibility for their correctness. The Trustee makes no representations or
warranties as to the validity or sufficiency of this Agreement (other than as
specifically set forth with respect to such party in Section 8.13) or of the
Certificates (other than the signature of the Trustee and authentication of the
Certificate Registrar on the Certificates) or of any Mortgage Loan or related
document. 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 or the Master
Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the
Collection Account by the Master Servicer, other than, subject to Section 8.01,
any funds held by or on behalf of the Trustee in accordance with Section 3.04.

                                      140
<PAGE>

                  SECTION 8.04. Trustee May Own Certificates.

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

                  SECTION 8.05. Trustee's Fees and Expenses.

                  (a) The Trustee shall withdraw from the Distribution Account
on each Distribution Date and pay to itself the Trustee Fee and, to the extent
that the funds therein are at any time insufficient for such purpose, the
Depositor shall pay such fees. The Trustee, or any director, officer, employee
or agent of the Trustee shall be indemnified by REMIC I and held harmless
against any loss, liability or expense (not including expenses, disbursements
and advances incurred or made by the Trustee (including the compensation and the
expenses and disbursements of its agents and counsel) in the ordinary course of
the Trustee's performance in accordance with the provisions of this Agreement)
incurred by the Trustee in connection with any claim or legal action or any
pending or threatened claim or legal action arising out of or in connection with
the acceptance or administration of its obligations and duties under this
Agreement (up to a limit of $600,000 per calendar year so long as any notes
issued pursuant to the Indenture are insured by a NIMS Insurer), other than any
loss, liability or expense (i) resulting from a breach of the Master Servicer's
obligations and duties under this Agreement and the Mortgage Loans (for which
the Master Servicer shall indemnify pursuant to Section 8.05(b)), (ii) that
constitutes a specific liability of the Trustee pursuant to Section 10.01(c) or
(iii) any loss, liability or expense incurred by reason of its willful
misfeasance, bad faith or negligence in the performance of its duties hereunder
or by reason of reckless disregard of its obligations and duties hereunder or as
a result of a breach of its obligations under Article X hereof. Any amounts
payable to the Trustee, or any director, officer, employee or agent of the
Trustee in respect of the indemnification provided by this paragraph (a), or
pursuant to any other right of reimbursement from the Trust Fund that the
Trustee, or any director, officer, employee or agent of the Trustee may have
hereunder in its capacity as such, may be withdrawn by the Trustee from the
Distribution Account at any time.

                  (b) The Master Servicer agrees to indemnify the Trustee from,
and hold it harmless against, any loss, liability or expense resulting from a
breach of the Master Servicer's obligations and duties under this Agreement.
Such indemnity shall survive the termination or discharge of this Agreement and
the resignation or removal of the Trustee. Any payment hereunder made by the
Master Servicer to the Trustee shall be from the Master Servicer's own funds,
without reimbursement from the Trust Fund therefor.

                  (c) The Master Servicer shall pay any annual rating agency
fees of the Rating Agencies for ongoing surveillance from its own funds without
right of reimbursement.

                  SECTION 8.06. Eligibility Requirements for Trustee.

                  The Trustee hereunder shall at all times be a corporation or
an association (other than the Depositor, the Seller, the Master Servicer or any
Affiliate of the foregoing) organized and doing business under the laws of any
state or the United States of America, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by federal or state
authority. If such corporation or association

                                      141
<PAGE>

publishes reports of conditions at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section the combined capital and surplus of such corporation or
association shall be deemed to be its combined capital and surplus as set forth
in its most recent report of conditions so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.07.

                  SECTION 8.07. Resignation and Removal of the Trustee.

                  The Trustee may at any time resign and be discharged from the
trust hereby created by giving written notice thereof to the Depositor, the NIMS
Insurer, the Certificate Insurer, the Master Servicer and the
Certificateholders. Upon receiving such notice of resignation of the Trustee,
the Depositor shall with the Certificate Insurer consent promptly appoint a
successor trustee acceptable to the NIMS Insurer by written instrument, in
duplicate, which instrument shall be delivered to the resigning Trustee and to
the successor trustee. A copy of such instrument shall be delivered to the
Certificateholders, the Certificate Insurer, the Trustee and the Master Servicer
by the Depositor. If no successor Trustee shall have been so appointed and
accepted appointment within 30 days after the giving of such notice of
resignation, then the Certificate Insurer may appoint a successor Trustee
acceptable to the NIMS Insurer. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

                  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor, the Certificate Insurer or the NIMS
Insurer, or if at any time the Trustee shall become incapable of acting, or
shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or of its
respective property shall be appointed, or any public officer shall take charge
or control of the Trustee or of its respective property or affairs for the
purpose of rehabilitation, conservation or liquidation, then the Depositor or
the NIMS Insurer may remove the Trustee and appoint a successor trustee
acceptable to the NIMS Insurer and the Certificate Insurer by written
instrument, in duplicate, which instrument shall be delivered to the Trustee so
removed and to the successor trustee. A copy of such instrument shall be
delivered to the Certificateholders, the Certificate Insurer and the Master
Servicer by the Depositor.

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights (or the NIMS Insurer upon failure of the Trustee to perform its
obligations hereunder) may at any time remove the Trustee and appoint a
successor trustee acceptable to the NIMS Insurer by written instrument or
instruments, in triplicate, signed by such Holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Depositor, one complete set to the Trustee so removed and one complete set to
the successor so appointed. A copy of such instrument shall be delivered to the
Certificateholders, the Certificate Insurer and the Master Servicer by the
Depositor.

                  Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

<PAGE>

                  SECTION 8.08. Successor Trustee.

                  Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer, the
Certificate Insurer 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. The predecessor trustee
shall deliver to the successor trustee all Mortgage Files and related documents
and statements, as well as all moneys, held by it hereunder (other than any
Mortgage Files at the time held by a Custodian, which Custodian shall become the
agent of any successor trustee hereunder), and the Depositor and the predecessor
trustee shall execute and deliver such instruments and do such other things as
may reasonably be required for more fully and certainly vesting and confirming
in the successor trustee all such rights, powers, duties and obligations.

                  No successor trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 and the appointment of such
successor trustee shall not result in a downgrading of any Class of Certificates
(without regard to the Policy) by either Rating Agency, as evidenced by a letter
from each Rating Agency.

                  Upon acceptance of appointment by a successor trustee as
provided in this Section, the Depositor shall mail notice of the succession of
such trustee hereunder to the Certificate Insurer and all Holders of
Certificates at their addresses as shown in the Certificate Register. If the
Depositor fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

                  SECTION 8.09. Merger or Consolidation of Trustee.

                  Any corporation or association into which the Trustee may be
merged or converted or with which it may be consolidated or any corporation or
association resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation or association succeeding to the
business of the Trustee shall be the successor of the Trustee hereunder,
provided such corporation or association shall be eligible under the provisions
of Section 8.06, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                  SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

                  Notwithstanding any other provisions hereof, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of REMIC I or property securing the same may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee and the NIMS Insurer to act as co-trustee or co-trustees, jointly
with the Trustee, or separate trustee or separate trustees, of all or any part
of REMIC I, and to vest in such Person or Persons, in such capacity, such title
to REMIC I, or any part thereof, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the Master
Servicer and the

                                      143
<PAGE>

Trustee may consider necessary or desirable. Any such co-trustee or separate
trustee shall be subject to the written approval of the Master Servicer, the
Certificate Insurer and the NIMS Insurer. If the Master Servicer, the
Certificate Insurer and the NIMS Insurer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
case a Master Servicer Event of Default shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee hereunder shall be required to meet the terms of eligibility
as a successor trustee under Section 8.06 hereunder and no notice to the Holders
of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall
be required under Section 8.08 hereof.

                  In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 8.10, all rights, powers, duties and
obligations conferred or imposed upon the Trustee shall be conferred or imposed
upon and exercised or performed by the Trustee and such separate trustee or
co-trustee jointly, except to the extent that under any law of any jurisdiction
in which any particular act or acts are to be performed by the Trustee (whether
as Trustee hereunder or as successor to the Master 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 REMIC I or any portion thereof in any such jurisdiction) shall be
exercised and performed by such separate trustee or co-trustee at the direction
of the Trustee.

                  Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article VIII. Each separate trustee and co-trustee, upon
its acceptance of the trust 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 Master Servicer, the Certificate
Insurer and the NIMS Insurer.

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

                  SECTION 8.11. Appointment of Custodians.

                  The Trustee may, with the consent of the Depositor and the
Master Servicer appoint one or more Custodians to hold all or a portion of the
Mortgage Files as agent for the Trustee, by entering into a Custodial Agreement.
The appointment of any Custodian may at any time be terminated and a substitute
Custodian appointed therefor upon the reasonable request of the Master Servicer
to the Trustee, the consent to which shall not be unreasonably withheld. The
Trustee shall pay any and all fees and expenses of any Custodian in accordance
with each Custodial Agreement (provided that if expenses of the kind that would
be reimbursable to the Trustee pursuant to Section

                                      144
<PAGE>

8.05 if incurred by the Trustee are incurred by the Custodian, the Trustee shall
be entitled to reimbursement under Section 8.05 for such kind of expenses to the
extent the Trustee has paid such expenses on behalf of the Custodian or for
which the Trustee has reimbursed the Custodian). The Trustee initially appoints
the Custodian as Custodian, and the Depositor and the Master Servicer consent to
such appointment. Subject to Article VIII hereof, the Trustee agrees to comply
with the terms of each Custodial Agreement and to enforce the terms and
provisions thereof against the Custodian for the benefit of the
Certificateholders having an interest in any Mortgage File held by such
Custodian. Each Custodian shall be a depository institution approved by the
Certificate Insurer or trust company subject to supervision by federal or state
authority, shall have combined capital and surplus of at least $10,000,000 and
shall be qualified to do business in the jurisdiction in which it holds any
Mortgage File. Each Custodial Agreement may be amended only as provided in
Section 11.01. In no event shall the appointment of any Custodian pursuant to a
Custodial Agreement diminish the obligations of the Trustee hereunder.

                  SECTION 8.12. Appointment of Office or Agency.

                  The Trustee shall designate an office or agency in the City of
New York where the Certificates may be surrendered for registration of transfer
or exchange, and presented for final distribution, and where notices and demands
to or upon the Trustee in respect of the Certificates and this Agreement may be
delivered. As of the Closing Date, the Trustee designates the office of its
agent located c/o DTC Transfer Agent Services, 55 Water Street, Jeanette Park
Entrance, New York, New York 10041 for such purposes.

                  SECTION 8.13. Representations and Warranties of the Trustee.

                  The Trustee hereby represents and warrants, to the Master
Servicer, the Certificate Insurer and the Depositor, as of the Closing Date,
that:

                  (i) It is a national banking association duly organized,
         validly existing and in good standing under the laws of the United
         States.

                  (ii) The execution and delivery of this Agreement by it, and
         the performance and compliance with the terms of this Agreement by it,
         will not violate its charter or bylaws or constitute a default (or an
         event which, with notice or lapse of time, or both, would constitute a
         default) under, or result in the breach of, any material agreement or
         other instrument to which it is a party or which is applicable to it or
         any of its assets.

                  (iii) It has the full power and authority to enter into and
         consummate all transactions contemplated by this Agreement, has duly
         authorized the execution, delivery and performance of this Agreement,
         and has duly executed and delivered this Agreement.

                  (iv) This Agreement, assuming due authorization, execution and
         delivery by the other parties hereto, constitutes a valid, legal and
         binding obligation of it, enforceable against it in accordance with the
         terms hereof, subject to (A) applicable bankruptcy, insolvency,
         receivership, reorganization, moratorium and other laws affecting the
         enforcement of creditors' rights generally, and (B) general principles
         of equity, regardless of whether such enforcement is considered in a
         proceeding in equity or at law.

                                      145
<PAGE>

                  (v) It is not in violation of, and its execution and delivery
         of this Agreement and its performance and compliance with the terms of
         this Agreement shall not constitute a violation of, any law, any order
         or decree of any court or arbiter, or any order, regulation or demand
         of any federal, state or local governmental or regulatory authority,
         which violation, in its good faith and reasonable judgment, is likely
         to affect materially and adversely either the ability of it to perform
         its obligations under this Agreement or its financial condition.

                  (vi) No litigation is pending or, to the best knowledge,
         threatened against it which would prohibit it from entering into this
         Agreement or, in its good faith reasonable judgment, is likely to
         materially and adversely affect either its ability to perform its
         obligations under this Agreement or its financial condition.

                                   ARTICLE IX

                                   TERMINATION

                  SECTION 9.01 Termination Upon Repurchase or Liquidation of All
                               Mortgage Loans.

                  (a) Subject to Section 9.02, the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer and
the Trustee (other than the obligations of the Master Servicer to the Trustee
pursuant to Section 8.05 and of the Master Servicer to provide for and the
Trustee to make payments in respect of the REMIC I Regular Interests, the REMIC
II Regular Interests or the Classes of Certificates as hereinafter set forth)
shall terminate upon payment to the Certificateholders and the deposit of all
amounts held by or on behalf of the Trustee and required hereunder to be so paid
or deposited on the Distribution Date coinciding with or following the earlier
to occur of (i) the purchase by the Terminator (as defined below) of all
Mortgage Loans and each REO Property remaining in REMIC I and (ii) the final
payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan or REO Property remaining in REMIC I; provided, however, that in
no event shall the trust created hereby continue beyond 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. The purchase by the Terminator of all Mortgage Loans
and each REO Property remaining in REMIC I shall be at a price (the "Termination
Price") equal to greater of (A) the aggregate fair market value of all of the
assets of REMIC I and (B) the sum of the Stated Principal Balance of the
Mortgage Loans (after giving effect to scheduled payments of principal due
during the related Due Period, to the extent received or advanced, and
unscheduled collections of principal received during the related Prepayment
Period) and the appraised fair market value of the REO Properties plus accrued
interest through the end of the calendar month preceding the month of the final
Distribution Date and any unreimbursed Advances and Servicing Advances(in the
case of fair market values required to be determined under (A) or (B) above, as
determined by the Terminator, the Trustee and, if the Terminator is not the NIMS
Insurer, the NIMS Insurer, as of the close of business on the third Business Day
next preceding the date upon which notice of any such termination is furnished
to Certificateholders pursuant to the third paragraph of this Section 9.01);
provided, however, such option may only be exercised if the Termination Price is
sufficient to pay (i) any amounts owed to the Certificate Insurer under the
Insurance Agreement and (ii) all interest accrued on, as well as amounts
necessary to retire the note balance of, each class of notes issued pursuant to
the Indenture and any amounts owed to the NIMS Insurer at the time the option is
exercised. If a termination pursuant to this Section 9.01(a) or Section 9.01(b)
will result in a claim under the Policy or if any amount owed to the Certificate
Insurer will not be fully reimbursed after such termination, the consent of the
Certificate Insurer shall be required prior to the Terminator exercising such
option.

                  (b) The Master Servicer (or if the Master Servicer fails to
exercise such right, the NIMS Insurer) shall have the right (the party
exercising such right, the "Terminator"), to purchase all of the Mortgage Loans
and each REO Property remaining in REMIC I pursuant to clause (i) of the
preceding paragraph no later than the Determination Date in the month
immediately preceding the Distribution Date on which the Certificates shall be
retired; provided, however, that the Terminator may elect to purchase all of the
Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i)
above only (A) if the aggregate Stated Principal Balance of the

                                      147
<PAGE>

Mortgage Loans and each REO Property remaining in the Trust Fund at the time of
such election is less than 10% of the aggregate Stated Principal Balance of the
Mortgage Loans as of the Cut-off Date and (B) if the Terminator is the Master
Servicer and is an affiliate of the Seller, the Master Servicer shall have
delivered to the Trustee, the Certificate Insurer and the NIMS Insurer a written
certification that the burdens of servicing the Mortgage Loans and REO
Properties remaining in REMIC I exceed the benefits of the Servicing Fees that
would be realized by the Master Servicer if it continued to service such assets
on behalf of the Trust Fund. By acceptance of the Residual Certificates, the
Holders of the Residual Certificates agree, in connection with any termination
hereunder, to pledge any amounts in excess of par, and to the extent received in
respect of such termination, to pay any such amounts to the Holders of the Class
CE Certificates.

                  (c) Notice of the liquidation of the REMIC I Regular Interests
shall be given promptly by the Trustee by letter to Certificateholders and the
Certificate Insurer mailed (a) in the event such notice is given in connection
with the purchase of the Mortgage Loans and each REO Property by the Terminator,
not earlier than the 15th day and not later than the 25th day of the month next
preceding the month of the final distribution on the Certificates or (b)
otherwise during the month of such final distribution on or before the
Determination Date in such month, in each case specifying (i) the Distribution
Date upon which the Trust Fund shall terminate and final payment in respect of
the REMIC I Regular Interests, the REMIC II Regular Interests and the
Certificates shall be made upon presentation and surrender of the related
Certificates at the office of the Trustee therein designated, (ii) the amount of
any such final payment, (iii) that no interest shall accrue in respect of the
REMIC I Regular Interests, the REMIC II Regular Interests or the Certificates
from and after the Interest Accrual Period relating to the final Distribution
Date therefor and (iv) that the Record Date otherwise applicable to such
Distribution Date is not applicable, payments being made only upon presentation
and surrender of the Certificates at the office of the Trustee. The Trustee
shall give such notice to the Certificate Registrar at the time such notice is
given to Certificateholders. In the event such notice is given in connection
with the purchase of all of the Mortgage Loans and each REO Property remaining
in REMIC I by the Terminator, the Terminator shall deliver to the Trustee for
deposit in the Distribution Account not later than the last Business Day
preceding the final Distribution Date on the Certificates an amount in
immediately available funds equal to the above-described purchase price. Upon
certification to the Trustee by a Servicing Officer of the making of such final
deposit, the Trustee shall promptly release or cause to be released to the
Terminator the Mortgage Files for the remaining Mortgage Loans, and the Trustee
shall execute all assignments, endorsements and other instruments necessary to
effectuate such transfer.

                  (d) Upon presentation of the Certificates by the
Certificateholders on the final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates the
amount otherwise distributable on such Distribution Date in accordance with
Section 4.01 in respect of the Certificates so presented and surrendered. Any
funds not distributed to any Holder or Holders of Certificates being retired on
such Distribution Date because of the failure of such Holder or Holders to
tender their Certificates shall, on such date, be set aside and held in trust by
the Trustee and credited to the account of the appropriate non-tendering Holder
or Holders. If any Certificates as to which notice has been given pursuant to
this Section 9.01 shall not have been surrendered for cancellation within six
months after the time specified in such notice, the Trustee shall mail a second
notice to the remaining non-tendering Certificateholders to surrender their
Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such
Certificates shall not have been

                                      148
<PAGE>

surrendered for cancellation, the Trustee shall, directly or through an agent,
mail a final notice to remaining related non-tendering Certificateholders
concerning surrender of their Certificates. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets remaining in the trust funds. If within one year after
the final notice any such Certificates shall not have been surrendered for
cancellation, the Trustee shall pay any amounts paid by the Certificate Insurer
to the Certificate Insurer and to Deutsche Bank Securities Inc. all such
amounts, and all rights of non-tendering Certificateholders in or to such
amounts shall thereupon cease. No interest shall accrue or be payable to any
Certificateholder on any amount held in trust by the Trustee as a result of such
Certificateholder's failure to surrender its Certificate(s) for final payment
thereof in accordance with this Section 9.01.

                  Immediately following the deposit of funds in trust hereunder
in respect of the Certificates, the Trust Fund shall terminate.

                  SECTION 9.02 Additional Termination Requirements.

                  (a) In the event that the Terminator purchases all the
         Mortgage Loans and each REO Property or the final payment on or other
         liquidation of the last Mortgage Loan or REO Property remaining in
         REMIC I pursuant to Section 9.01, the Trust Fund shall be terminated in
         accordance with the following additional requirements:

                  (i) The Trustee shall specify the first day in the 90-day
         liquidation period in a statement attached to each Trust REMIC's final
         Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall
         satisfy all 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;

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

                  (iii) At the time of the making of the final payment on the
         Certificates, the Trustee shall distribute or credit, or cause to be
         distributed or credited, to the Holders of the 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) At the expense of the applicable Terminator (or in the
         event of termination under Section 9.01(a)(ii), at the expense of the
         Trustee), the Trustee shall prepare or cause to be prepared the
         documentation required in connection with the adoption of a plan of
         liquidation of each Trust REMIC pursuant to this Section 9.02.

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

                                REMIC PROVISIONS

                  SECTION 10.01. REMIC Administration.

                  (a) The Trustee shall elect to treat each Trust REMIC as a
REMIC under the Code and, if necessary, under applicable state law. Each such
election will be made by the Trustee on Form 1066 or other appropriate federal
tax or information return or any appropriate state return for the taxable year
ending on the last day of the calendar year in which the Certificates are issued
and copies of such forms and election shall be furnished to the Certificate
Insurer. For the purposes of the REMIC election in respect of REMIC I, (i) the
REMIC I Regular Interests shall be designated as the Regular Interests in REMIC
I and (ii) the Class R-I Interest shall be designated as the Residual Interest
in REMIC I. The Class A Certificates, the Mezzanine Certificates, the Class CE
Certificates and the Class P Certificates shall be designated as the Regular
Interests in REMIC II and the Class R-II Interest shall be designated as the
Residual Interest in REMIC II. The Trustee shall not permit the creation of any
"interests" in any Trust REMIC (within the meaning of Section 860G of the Code)
other than the REMIC I Regular Interests and the interests represented by the
Certificates.

                  (b) The Closing Date is hereby designated as the "Startup Day"
of each Trust REMIC within the meaning of Section 860G(a)(9) of the Code.

                  (c) The Trustee shall pay out of its own funds, without any
right of reimbursement, any and all expenses relating to any tax audit of the
Trust Fund caused by the Trustee (including, but not limited to, any
professional fees or any administrative or judicial proceedings with respect to
any Trust REMIC that involve the Internal Revenue Service or state tax
authorities), other than the expense of obtaining any tax related Opinion of
Counsel except as specified herein. The Trustee, as agent for each Trust REMIC's
tax matters person, shall (i) act on behalf of the Trust Fund in relation to any
tax matter or controversy involving any Trust REMIC and (ii) represent the Trust
Fund in any administrative or judicial proceeding relating to an examination or
audit by any governmental taxing authority with respect thereto. The Holder of
the largest Percentage Interest of each Class of Residual Certificates shall be
designated, in the manner provided under Treasury regulations section
1.860F-4(d) and Treasury regulations section 301.6231(a)(7)-1, as the tax
matters person of the related REMIC created hereunder. By their acceptance
thereof, the Holder of the largest Percentage Interest of the Residual
Certificates hereby agrees to irrevocably appoint the Trustee or an Affiliate as
its agent to perform all of the duties of the tax matters person for the Trust
Fund.

                  (d) The Trustee shall prepare, sign and file all of the Tax
Returns in respect of each REMIC created hereunder. The expenses of preparing
and filing such returns shall be borne by the Trustee without any right of
reimbursement therefor. The Master Servicer shall provide on a timely basis to
the Trustee or its designee such information with respect to the assets of the
Trust Fund as is in its possession and reasonably required by the Trustee to
enable it to perform its obligations under this Article.

                  (e) The Trustee shall perform on behalf of each Trust REMIC
all reporting and other tax compliance duties that are the responsibility of
such REMIC under the Code, the REMIC

                                      150
<PAGE>

Provisions or other compliance guidance issued by the Internal Revenue Service
or any state or local taxing authority. Among its other duties, as required by
the Code, the REMIC Provisions or other such compliance guidance, the Trustee
shall provide (i) to any Transferor of a Residual Certificate such information
as is necessary for the application of any tax relating to the transfer of a
Residual Certificate to any Person who is not a Permitted Transferee, (ii) to
the Certificateholders such information or reports as are required by the Code
or the REMIC Provisions including reports relating to interest, original issue
discount and market discount or premium (using the Prepayment Assumption as
required) and (iii) to the Internal Revenue Service the name, title, address and
telephone number of the person who will serve as the representative of each
Trust REMIC. The Master Servicer shall provide on a timely basis to the Trustee
such information with respect to the assets of the Trust Fund, including,
without limitation, the Mortgage Loans, as is in its possession and reasonably
required by the Trustee to enable each of them to perform their respective
obligations under this subsection. In addition, the Depositor shall provide or
cause to be provided to the Trustee within ten (10) days after the Closing Date,
all information or data that the Trustee reasonably determines to be relevant
for tax purposes as to the valuations and issue prices of the Certificates,
including, without limitation, the price, yield, prepayment assumption and
projected cash flow of the Certificates.

                  (f) The Trustee shall take such action and shall cause each
REMIC created hereunder to take such action as shall be necessary to create or
maintain the status thereof as a REMIC under the REMIC Provisions (and the
Master Servicer shall assist it, to the extent reasonably requested by it). The
Trustee shall not take any action, cause the Trust Fund to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of any Trust REMIC as a REMIC or (ii) result in the imposition of a tax
upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) (either such
event, an "Adverse REMIC Event") unless the Trustee, the Certificate Insurer and
the NIMS Insurer have received an Opinion of Counsel, addressed to the Trustee,
the NIMS Insurer and the Certificate Insurer (at the expense of the party
seeking to take such action but in no event at the expense of the Trustee) to
the effect that the contemplated action shall not, with respect to any Trust
REMIC, endanger such status or result in the imposition of such a tax, nor shall
the Master Servicer take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee, the Certificate Insurer and the NIMS Insurer
has advised it in writing that it has received an Opinion of Counsel to the
effect that an Adverse REMIC Event could occur with respect to such action. In
addition, prior to taking any action with respect to any Trust REMIC or the
respective assets of each, or causing any Trust REMIC to take any action, which
is not contemplated under the terms of this Agreement, the Master Servicer shall
consult with the Trustee, the NIMS Insurer, the Certificate Insurer or its
designee, in writing, with respect to whether such action could cause an Adverse
REMIC Event to occur with respect to any Trust REMIC, and the Master Servicer
shall not take any such action or cause any Trust REMIC to take any such action
as to which the Trustee, the Certificate Insurer or the NIMS Insurer has advised
it in writing that an Adverse REMIC Event could occur. The Trustee, the
Certificate Insurer or the NIMS Insurer may consult with counsel to make such
written advice, and the cost of same shall be borne by the party seeking to take
the action not permitted by this Agreement, but in no event shall such cost be
an expense of the Trustee. At all times as may be required by the Code, the
Master Servicer on behalf of the Trustee shall ensure that substantially all of
the assets of any Trust REMIC

                                      151
<PAGE>

shall consist of "qualified mortgages" as defined in Section 860G(a)(3) of the
Code and "permitted investments" as defined in Section 860G(a)(5) of the Code.

                  (g) In the event that any tax is imposed on "prohibited
transactions" of any REMIC created hereunder as defined in Section 860F(a)(2) of
the Code, on the "net income from foreclosure property" of such REMIC as defined
in Section 860G(c) of the Code, on any contributions to any such REMIC after the
Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax
is imposed by the Code or any applicable provisions of state or local tax laws,
such tax shall be charged (i) to the Trustee pursuant to Section 10.03 hereof,
if such tax arises out of or results from a breach by the Trustee of any of its
obligations under this Article X, (ii) to the Master Servicer pursuant to
Section 10.03 hereof, if such tax arises out of or results from a breach by the
Master Servicer of any of its obligations under Article III or this Article X,
or otherwise (iii) against amounts on deposit in the Distribution Account and
shall be paid by withdrawal therefrom.

                  (h) On or before April 15th of each calendar year, commencing
April 15, 2005, the Trustee shall deliver to the Master Servicer, the NIMS
Insurer, the Certificate Insurer and each Rating Agency a Certificate from a
Responsible Officer of the Trustee stating, without regard to any action taken
by any party other than the Trustee, the Trustee's compliance with this Article
X.

                  (i) The Trustee shall, for federal income tax purposes,
maintain books and records with respect to each Trust REMIC on a calendar year
and on an accrual basis. The Trustee shall apply for an Employer Identification
Number for the Trust Fund from the Internal Revenue Service via a Form SS-4 or
such other form as is appropriate.

                  (j) Following the Startup Day, the Trustee shall not accept
any contributions of assets to any Trust REMIC other than in connection with any
Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03
unless it shall have received an Opinion of Counsel to the effect that the
inclusion of such assets in the Trust Fund shall not cause the related REMIC to
fail to qualify as a REMIC at any time that any Certificates are outstanding or
subject such REMIC to any tax under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

                  (k) Neither the Trustee nor the Master Servicer shall enter
into any arrangement by which any Trust REMIC shall receive a fee or other
compensation for services nor permit any such REMIC to receive any income from
assets other than the Mortgage Pool which are deemed to constitute "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.

                  SECTION 10.02. Prohibited Transactions and Activities.

                  None of the Depositor, the Master Servicer or the Trustee
shall sell, dispose of or substitute for any of the Mortgage Loans (except in
connection with (i) the foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of REMIC I, (iii) the termination of

<PAGE>

nor sell or dispose of any investments in the Collection Account or the
Distribution Account for gain, nor accept any contributions to any Trust REMIC
after the Closing Date (other than a Qualified Substitute Mortgage Loan
delivered in accordance with Section 2.03), unless it has received an Opinion of
Counsel, addressed to the Trustee and the NIMS Insurer (at the expense of the
party seeking to cause such sale, disposition, substitution, acquisition or
contribution but in no event at the expense of the Trustee) that such sale,
disposition, substitution, acquisition or contribution shall not (a) affect
adversely the status of any Trust REMIC as a REMIC or (b) cause any Trust REMIC
to be subject to a tax on "prohibited transactions" or "contributions" pursuant
to the REMIC Provisions.

                  SECTION 10.03. Master Servicer and Trustee Indemnification.

                  (a) The Trustee agrees to indemnify the Trust Fund, the NIMS
Insurer, the Certificate Insurer, the Depositor and the Master Servicer for any
taxes and costs including, without limitation, any reasonable attorneys fees
imposed on or incurred by the Trust Fund, the Depositor or the Master Servicer,
caused solely by the Trustee's failure to act in accordance with its standard of
care set forth in this Article X or any state, local or franchise taxes imposed
upon the Trust as a result of the location of the Trustee.

                  (b) The Master Servicer agrees to indemnify the Trust Fund,
the Certificate Insurer, the NIMS Insurer, the Depositor and the Trustee for any
taxes and costs including, without limitation, any reasonable attorneys' fees
imposed on or incurred by the Trust Fund, the Depositor or the Trustee, as a
result of a breach of the Master Servicer's covenants set forth in Article III
or this Article X or any state, local or franchise taxes imposed upon the Trust
as a result of the location of the Master Servicer or any subservicer.

                            MISCELLANEOUS PROVISIONS

                  SECTION 11.01. Amendment.

time to time by the Depositor, the Master Servicer, the Trustee and, if
applicable, the Custodian with the consent of the NIMS Insurer and without the
consent of any of the Certificateholders, (i) to cure any ambiguity or defect,
(ii) to correct, modify or supplement any provisions herein (including to give

Insurer and the Trustee to such effect or (ii) confirmation from the Rating
Agencies that such amendment shall not result in the reduction or withdrawal of
the rating of any outstanding Class of Certificates (without regard to the
Policy). No amendment shall be deemed to adversely affect in any material
respect the interests of any Certificateholder who shall have consented thereto,
and no Opinion of Counsel shall be required to address the effect of any such
amendment on any such consenting Certificateholder.

                   This Agreement or any Custodial Agreement may also be amended
from time to time by the Depositor, the Master Servicer, the NIMS Insurer and
the Trustee with the consent of the NIMS Insurer and the Holders of Certificates
entitled to at least 66% of the Voting Rights for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or any Custodial Agreement or of modifying in any manner the
rights of the Holders of Certificates; provided, however, that no such amendment

result in the reduction or withdrawal of the rating of any outstanding Class of
Certificates with respect to which it is a Rating Agency) in a manner other than
as described in (i), or (iii) modify the consents required by the immediately
preceding clauses (i) and (ii) without the consent of the Holders of all
Certificates then outstanding. Notwithstanding any other provision of this
Agreement, for purposes of the giving or withholding of consents pursuant to
this Section 11.01, Certificates registered in the name of the Depositor or the
Master Servicer or any Affiliate thereof shall be entitled to Voting Rights with
respect to matters affecting such Certificates.

Policy). The Master Servicer shall send a copy of any proposed amendment to this
Agreement to the Certificate Insurer prior to execution of the amendment. The
Certificate Insurer shall notify the Trustee in writing, within a reasonable
time following its receipt of a copy of the proposed

                                      154
<PAGE>

amendment, whether the Certificate Insurer has determined that its consent to
such amendment is required.

                  Notwithstanding any contrary provision of this Agreement, none
of the Trustee, the Certificate Insurer or the NIMS Insurer shall consent to any
amendment to this Agreement unless it shall have first received an Opinion of
Counsel satisfactory to the NIMS Insurer and the Certificate Insurer to the
effect that such amendment shall not result in the imposition of any tax on any
Trust REMIC pursuant to the REMIC Provisions or cause any Trust REMIC to fail to
qualify as a REMIC at any time that any Certificates are outstanding.

                  Notwithstanding any of the other provisions of this Section
11.01, none of the Depositor, the Master Servicer or the Trustee shall enter
into any amendment of this Agreement that would significantly change the
permitted activities of the Trust Fund without the consent of the NIMS Insurer,
the Certificate Insurer and the holders of Certificates that represent more than
50.00% of the aggregate Certificate Principal Balance of all Certificates.

                  Promptly after the execution of any such amendment the Trustee
shall furnish a copy of such amendment to each Certificateholder and the
Certificate Insurer.

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 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.

                  The cost of any Opinion of Counsel to be delivered pursuant to
this Section 11.01 shall be borne by the Person seeking the related amendment,
but in no event shall such Opinion of Counsel be an expense of the Trustee.

                  The Trustee may, but shall not be obligated to enter into any
amendment pursuant to this Section that affects its respective rights, duties
and immunities under this Agreement or otherwise.

                  SECTION 11.02. Recordation of Agreement; Counterparts.

                  To the extent permitted by applicable law, this Agreement is

all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Certificateholders, but
only upon direction of the Trustee accompanied by an Opinion of Counsel to the
effect that such recordation materially and beneficially affects the interests
of the Certificateholders.

                  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. 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 representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

                  No Certificateholder shall have any right to vote (except as
expressly provided for 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 any 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 person 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 of any
provision 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 (i)
such Holder previously shall have given to the Trustee and the Certificate
Insurer a written notice of default and of the continuance thereof, as
hereinbefore provided, and (ii) the Holders of Certificates entitled to at least
25% of the Voting Rights shall have made written request upon the Trustee to
institute such action, suit or proceeding in the name of the Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee, for 15 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 is understood and intended, and 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 whatsoever by virtue of any provision of this Agreement to affect,
disturb or prejudice the rights of the Holders of any other of such
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 equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section, each and every Certificateholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

                  SECTION 11.09. Grant of Security Interest.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Depositor to the Trustee be, and be
construed as, a sale of the Mortgage Loans by the Depositor and not a pledge of
the Mortgage Loans by the Depositor to secure a debt or other obligation of the
Depositor or the Seller. However, in the event that, notwithstanding the
aforementioned intent of the parties, the Mortgage Loans are held to be property
of the Depositor or the Seller, then, (a) it is the express intent of the
parties that such conveyance be deemed a pledge

                                      158
<PAGE>

of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other
obligation of the Depositor or the Seller and (b)(1) this Agreement shall also
be deemed to be a security agreement within the meaning of Articles 8 and 9 of
the Uniform Commercial Code as in effect from time to time in the State of New
York; (2) the conveyance provided for in Section 2.01 hereof shall be deemed to
be a grant by the Seller and the Depositor to the Trustee of a security interest
in all of the Seller's and the Depositor's right, title and interest in and to
the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans
in accordance with the terms thereof and all proceeds of the conversion,
voluntary or involuntary, of the foregoing into cash, instruments, securities or
other property, including without limitation all amounts, other than investment
earnings, from time to time held or invested in the Collection Account and the
Distribution Account, whether in the form of cash, instruments, securities or
other property; (3) the obligations secured by such security agreement shall be
deemed to be all of the Depositor's obligations under this Agreement, including
the obligation to provide to the Certificateholders the benefits of this
Agreement relating to the Mortgage Loans and the Trust Fund; and (4)
notifications to persons holding such property, and acknowledgments, receipts or
confirmations from persons holding such property, shall be deemed notifications
to, or acknowledgments, receipts or confirmations from, financial
intermediaries, bailees or agents (as applicable) of the Trustee for the purpose
of perfecting such security interest under applicable law. Accordingly, the
Depositor hereby grants to the Trustee a security interest in the Mortgage Loans
and all other property described in clause (2) of the preceding sentence, for
the purpose of securing to the Trustee on behalf of the Certificateholders the
performance by the Depositor of the obligations described in clause (3) of the
preceding sentence. Notwithstanding the foregoing, the parties hereto intend the
conveyance pursuant to Section 2.01 and the transfer pursuant to the Mortgage
Loan Purchase Agreement to be a true, absolute and unconditional sale of the
Mortgage Loans and assets constituting the Trust Fund by the Depositor to the
Trustee.

                  SECTION 11.10 Third Party Rights.

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

                    Each of the Depositor, the Master Servicer and the Trustee,

specifically set forth above may be exercised by the Insured Certificateholders
only with the prior written consent of the Certificate Insurer.

                  SECTION 12.02. Trustee to Act Solely with Consent of

Section 11.01; or (ii) undertake any litigation pursuant to Section 8.02(a)(iii)
at the request or direction of the Certificateholders, without the prior written
consent of the Certificate Insurer which consent shall not be unreasonably
withheld; provided, however, nothing contained herein shall prohibit or prevent
the Trustee from defending itself or the Trust Fund or taking any action related
thereto.

                  SECTION 12.03. Trust Fund and Accounts Held for Benefit of
                                 Certificate Insurer.

                    The Trustee shall hold the Trust Fund and the Mortgage Files
for the benefit of the Certificateholders and the Certificate Insurer and all
references in this Agreement (including, without limitation, in Sections 2.01
and 2.02) and in the Certificates to the benefit of Holders of the Certificates
shall be deemed to include the Certificate Insurer. The Trustee shall cooperate
in all reasonable respects with any reasonable request by the Certificate
Insurer for action to preserve or enforce the Certificate Insurer's rights or
interests under this Agreement and the Certificates.

                  The Master Servicer hereby acknowledges and agrees that it

Insurer, and all references in this Agreement (including, without limitation, in
Section 3.01) to the benefit of or actions on behalf of the Certificateholders
shall be deemed to include the Certificate Insurer. Unless a Certificate Insurer
Default has occurred and is continuing, neither the Master Servicer nor the
Depositor shall undertake any litigation pursuant to Section 6.03 (other than

Insurer.

                  SECTION 12.04. Claims Upon the Policy; Policy Payments
                                 Account.

                  (a) If, at or before 2:00 p.m., New York time, on the second
Business Day prior to a Distribution Date, the Trustee determines that a
Guaranteed Distributions Shortfall for such Distribution Date is greater than
zero, then the Trustee shall give notice to the Certificate Insurer by telephone
or telecopy of the amount of such Guaranteed Distributions Shortfall. Such
notice of such Guaranteed Distributions Shortfall shall be confirmed in writing
in the form set forth as Exhibit A to the Endorsement to the Policy, to the
Certificate Insurer and the Fiscal Agent (as defined in the Policy), if any, at
or before 2:00 p.m. New York time on the second Business Day prior to such
Distribution Date. Following Receipt (as defined in the Policy) by the
Certificate Insurer of such notice in such form, the Certificate Insurer or the
Fiscal Agent will pay any amount payable under the Policy on the later to occur
of (i) 12:00 noon New York time on the second Business Day following such
receipt and (ii) 12:00 noon New York time on the Distribution Date to which such
Guaranteed Distributions Shortfall relates, as provided in the Endorsement to
the Policy.

                  (b) The Trustee shall establish a segregated non-interest
bearing trust account for the benefit of Holders of the Insured Certificates and
the Certificate Insurer referred to herein as the "Policy Payments Account" over
which the Trustee shall have exclusive control and sole right of withdrawal. The
Trustee shall deposit any amount paid under the Policy in the Policy Payments
Account and distribute such amount only for purposes of payment to Holders of
Insured Certificates of the Guaranteed Distributions Shortfall or any amount in
respect of a Preference Claim (as defined in the Policy) for which a claim under
the Policy was made, and such amount may not be applied to satisfy any costs,
expenses or liabilities of the Master Servicer, the Trustee or the Trust Fund.
Amounts paid under the Policy shall be transferred to the Distribution Account
in accordance with the next succeeding paragraph and disbursed by the Trustee to
Holders of Insured Certificates in accordance with Section 4.01(h) (or, in the
case of an amount in respect of a Preference Claim, to the related Holders of
Insured Certificates as contemplated in Section 12.04(d)). It shall not be
necessary for such payments to be made by checks or wire transfers separate from
the checks or wire transfers used to pay the other distributions to be made to
such Holders pursuant to Section 4.01. However, the amount of any payment of
principal of or interest on the Insured Certificates to be paid from funds
transferred from the Policy Payments Account shall be noted as provided in
paragraph (c) below in the Certificate Register and in the statement to be
furnished to Holders of the Insured Certificates pursuant to Section 4.02. Funds
held in the Policy Payments Account shall not be invested.

                  On any Distribution Date with respect to which a claim has
been made under the Policy, the amount of any funds received by the Trustee as a
result of any claim under the Policy, to the extent required to pay the
Guaranteed Distributions Shortfall on such Distribution Date, shall be withdrawn
from the Policy Payments Account and deposited in the Distribution Account and
applied by the Trustee, directly to the payment in full of the Guaranteed
Distributions Shortfall due on the

                                      161
<PAGE>

Insured Certificates. Funds received by the Trustee as a result of any claim
under the Policy shall be deposited by the Trustee in the Policy Payments
Account and used solely for payment to the Holders of the Insured Certificates
and may not be applied to satisfy any costs, expenses or liabilities of the
Master Servicer, the Trustee or the Trust Fund. Any funds remaining in the
Policy Payments Account on the first Business Day following a Distribution Date
shall be remitted to the Certificate Insurer, pursuant to the instructions of
the Certificate Insurer, by the end of such Business Day.

                  (c) The Trustee shall keep a complete and accurate record of
the amount of interest and principal paid in respect of any Insured Certificate
from moneys received under the Policy. The Certificate Insurer shall have the
right to inspect such records at reasonable times during normal business hours
upon two Business Days' prior notice to the Trustee.

                  (d) The Trustee shall promptly notify the Certificate Insurer
and Fiscal Agent of any proceeding or the institution of any action, of which a
Responsible Officer of the Trustee has actual knowledge, seeking the avoidance
as a preferential transfer under applicable bankruptcy, insolvency, receivership
or similar law (a "Preference Claim") of any Guaranteed Distribution (as defined
in the Policy) made with respect to the Insured Certificates. Each Holder of the
Insured Certificates, by its purchase of such Certificates, the Master Servicer
and the Trustee hereby agree that the Certificate Insurer (so long as no
Certificate Insurer Default has occurred and is continuing) may at any time
during the continuation of any proceeding relating to a Preference Claim direct
all matters relating to such Preference Claim, including, without limitation,
(i) the direction of any appeal of any order relating to such Preference Claim
and (ii) the posting of any surety, supersedeas or performance bond pending any
such appeal. In addition and without limitation of the foregoing, the
Certificate Insurer shall be subrogated to the rights of the Master Servicer,
the Trustee and each Holder of the Insured Certificates in the conduct of any
such Preference Claim, including, without limitation, all rights of any party to
an adversary proceeding action with respect to any court order issued in
connection with any such Preference Claim.

                  SECTION 12.05. Effect of Payments by Certificate Insurer;
                                 Subrogation.

                  Anything herein to the contrary notwithstanding, any payment
with respect to principal of or interest on any of the Insured Certificates
which is made with moneys received pursuant to the terms of the Policy shall not
be considered payment of such Certificates from the Trust Fund and shall not
result in the payment of or the provision for the payment of the principal of or
interest on such Certificates within the meaning of Section 4.01. The Depositor,
the Master Servicer and the Trustee acknowledge, and each Holder of an Insured
Certificate by its acceptance of a such Certificate agrees, that without the
need for any further action on the part of the Certificate Insurer, the
Depositor, the Master Servicer or the Trustee (i) to the extent the Certificate
Insurer makes payments, directly or indirectly, on account of principal of or
interest on any Insured Certificates to the Holders of such Certificates, the
Certificate Insurer will be fully subrogated to the rights of such Holders to
receive such principal and interest from the Trust Fund and (ii) the Certificate
Insurer shall be paid such principal and interest but only from the sources and
in the manner provided herein for the payment of such principal and interest.

                  The Trustee and the Master Servicer shall cooperate in all
respects with any reasonable request by the Certificate Insurer for action to
preserve or enforce the Certificate Insurer's

                                      162
<PAGE>

rights or interests under this Agreement without limiting the rights or
affecting the interests of the Holders as otherwise set forth herein.

                  SECTION 12.06. Notices to Certificate Insurer.

                  All notices, statements, reports, certificates or opinions
required by this Agreement to be sent to any other party hereto or to any of the
Certificateholders shall also be sent to the Certificate Insurer.

                  SECTION 12.07 Third Party Beneficiary.

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

                  SECTION 12.08 Trustee to Hold the Policy.

                  The Trustee shall hold the Policy in trust as agent for the
Holders of the Insured Certificates for the purpose of making claims thereon and
distributing the proceeds thereof. Upon the later of (i) the date upon which the
Certificate Principal Balance of the Insured Certificates has been reduced to
zero and all Guaranteed Distributions (as defined in the Policy) have been made
and (ii) the date the Term of This Policy (as defined in the Policy) ends, the
Trustee shall surrender the Policy to the Certificate Insurer for cancellation.
Neither the Policy nor the amounts paid on the Policy will constitute part of
the Trust Fund or assets of any Trust REMIC created by this Agreement. Each
Holder of Insured Certificates, by accepting its Certificates, appoints the
Trustee as attorney-in-fact for the purpose of making claims on the Policy.

                  SECTION 12.09 Termination of Certain of Certificate Insurer's
                                Rights.

                  Notwithstanding anything to the contrary anywhere in this
Agreement, all rights of the Certificate Insurer, except in the case of any
right to indemnification hereunder, shall permanently cease to be operable upon
the latest to occur of (A) the date upon which the Certificate Principal Balance
of the Insured Certificates has been reduced to zero and all Guaranteed
Distributions (as defined in the Policy) have been made, (B) the date the Term
of This Policy (as defined in the Policy) ends and (C) the payment in full to
the Certificate Insurer of all amounts paid under the Policy plus interest at
the Late Payment Rate thereon from the date such payment was made and any other
amounts owing to the Certificate Insurer under the Insurance Agreement.

Certificate Registrar and any agent of the Depositor, the Master Servicer, the
Trustee or the Certificate Registrar may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

the Depositor and the Trustee assumes no responsibility for their correctness.

REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

Certificate Registrar and any agent of the Depositor, the Master Servicer, the
Trustee or the Certificate Registrar may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee and the rights of
the Certificateholders under the Agreement at any time by the Depositor, the

Assets" to acquire this Certificate shall be made except in accordance with
Section 5.02(c) of the Agreement.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any transfer or exchange of Certificates.

                  The Depositor, the Master Servicer, the Trustee and the
Certificate Registrar and any agent of the Depositor, the Master Servicer, the
Trustee or the Certificate Registrar may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

Agreement following the earlier of (i) the final payment or other liquidation

Assets" to acquire this Certificate shall be made except in accordance with
Section 5.02(c) of the Agreement.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any transfer or exchange of Certificates.

                  The Depositor, the Master Servicer, the Trustee and the
Certificate Registrar and any agent of the Depositor, the Master Servicer, the

Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

right cannot be exercised until the Optional Termination Date.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable

the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the

such Holder's attorney duly authorized in writing, and thereupon one or more new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest will be issued to the designated transferee or
transferees.

                  The Certificates are issuable in fully registered form only

limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

                  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

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, the Trustee or the Master Servicer 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. None of the Depositor,
the Certificate Registrar or 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, the Certificate
Registrar and the Master Servicer 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 to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

                  The Depositor, the Master Servicer, the Trustee and the
Certificate Registrar and any agent of the Depositor, the Master Servicer, the
Trustee or the Certificate Registrar may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

adjustable-rate and fixed-rate first lien mortgage loans (the "Mortgage Loans")
formed and sold by

                       AMERIQUEST MORTGAGE SECURITIES INC.

         THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR
         INTEREST IN AMERIQUEST MORTGAGE SECURITIES INC., THE MASTER
         SERVICER, THE TRUSTEE OR ANY OF THEIR RESPECTIVE AFFILIATES.
         NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE

         STATES.

                  This certifies that Ameriquest Mortgage Company is the
registered owner of a Percentage Interest specified above in that certain
beneficial ownership interest evidenced by all the Class R Certificates in a

Agreement), the Master Servicer and the Trustee, a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined

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 the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 25th day of each month or, if such 25th day is not a Business Day,

                  All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by

entitled thereto if such Person shall have so notified the Trustee in writing at

                  This Certificate is one of a duly authorized issue of
Certificates designated as Asset- Backed Pass-Through Certificates of the Series
specified on the face hereof (herein called the "Certificates") and representing
a Percentage Interest in the Class of Certificates specified on the face

                                     A-18-4

<PAGE>

hereof equal to the denomination specified on the face hereof divided by the
aggregate Certificate Principal Balance of the Class of Certificates specified
on the face hereof.

                  The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee and the rights of
the Certificateholders under the Agreement at any time by the Depositor, the
Master Servicer and the Trustee with the consent of the Holders of Certificates
entitled to at least 66% of the Voting Rights. 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 exchange herefor 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
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest will be issued to the designated transferee or
transferees.

                  The Certificates are issuable in fully registered form only
without coupons in Classes and denominations representing Percentage Interests
specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

                  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 and the Certificate Registrar 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 F-1,
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, the
Trustee or the Master Servicer in their

                                     A-18-5

<PAGE>

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. None of the Depositor, the Certificate Registrar or 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, the Certificate Registrar and the Master Servicer
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 to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

                  Prior to registration of any transfer, sale or other
disposition of this Certificate, the proposed transferee shall provide to the
Trustee (i) an affidavit to the effect that such transferee is any Person other
than a Disqualified Organization or the agent (including a broker, nominee or
middleman) of a Disqualified Organization, and (ii) a certificate that
acknowledges that (A) the Class R Certificates have been designated as a
residual interest in a REMIC, (B) it will include in its income a PRO RATA share
of the net income of the Trust Fund and that such income may be an "excess
inclusion," as defined in the Code, that, with certain exceptions, cannot be
offset by other losses or benefits from any tax exemption, and (C) it expects to
have the financial means to satisfy all of its tax obligations including those
relating to holding the Class R Certificates. Notwithstanding the registration
in the Certificate Register of any transfer, sale or other disposition of this
Certificate to a Disqualified Organization or an agent (including a broker,
nominee or middleman) of a Disqualified Organization, such registration shall be
deemed to be of no legal force or effect whatsoever and such Person shall not be
deemed to be a Certificateholder for any purpose, including, but not limited to,
the receipt of distributions in respect of this Certificate.

                  The Holder of this Certificate, by its acceptance hereof,
shall be deemed to have consented to the provisions of Section 5.02 of the
Agreement and to any amendment of the Agreement deemed necessary by counsel of
the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause the Trust
Fund to cease to qualify as a REMIC or cause the imposition of a tax upon the
REMIC.

                  No transfer of this Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any transfer or exchange of Certificates.

                  The Depositor, the Master Servicer, the Trustee and the
Certificate Registrar and any agent of the Depositor, the Master Servicer, the
Trustee or the Certificate Registrar may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I, and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                        MORTGAGE LOAN PURCHASE AGREEMENT

         This is a Mortgage Loan Purchase Agreement (the "Agreement"), dated
July 27, 2004, between Ameriquest Mortgage Company, a Delaware corporation (the
"Seller"), and Ameriquest Mortgage Securities Inc., a Delaware corporation (the
"Purchaser").

                              Preliminary Statement
                              ---------------------

                  The Seller intends to sell the Mortgage Loans (as hereinafter
defined) to the Purchaser on the terms and subject to the conditions set forth
in this Agreement. The Purchaser shall deposit the Mortgage Loans into a
mortgage pool constituting the Trust Fund. The Trust Fund will be evidenced by a
single series of asset-backed pass-through certificates designated as Series
2004-R8 (the "Certificates"). The Certificates will consist of eighteen classes
of certificates. The Class M-10 Certificates, the Class CE Certificates, the
Class P Certificates and the Class R Certificates (collectively, the
"Non-Offered Certificates") will be delivered to the Seller or its designee as
partial consideration for the Mortgage Loans as further described below.

                  The Certificates will be issued pursuant to a Pooling and
Servicing Agreement relating to the Series 2004-R8 Certificates, dated as of
August 1, 2004 (the "Pooling and Servicing Agreement"), among the Purchaser as
depositor (in such capacity, the "Depositor"), the Seller as master servicer (in
such capacity the "Master Servicer") and Deutsche Bank National Trust Company as
trustee (the "Trustee"). Pursuant to the Pooling and Servicing Agreement, the
Depositor will assign all of its right, title and interest in and to the
Mortgage Loans, together with its rights under this Agreement, to the Trustee
for the benefit of the Certificateholders. Capitalized terms used but not
defined herein shall have the meanings set forth in the Pooling and Servicing
Agreement.

                  The parties hereto agree as follows:

                  SECTION 1. AGREEMENT TO PURCHASE. The Seller hereby sells, and
the Purchaser hereby purchases, as of August 5, 2004 (the "Closing Date"),
certain adjustable-rate and fixed-rate conventional, one- to four-family,
residential mortgage loans (the "Mortgage Loans"), having an aggregate principal
balance as of the close of business on August 1, 2004 (the "Cut-off Date") of
$2,500,000,164.75, after giving effect to all payments due on the Mortgage Loans
on or before the Cut-off Date (the "Closing Balance"), whether or not received,
including the right to any Prepayment Charges collected after the Cut-off Date
from the Mortgagors in connection with any Principal Prepayments on the Mortgage
Loans. Any payments (including Prepayment Charges) collected on or before the
Cut-off Date, including all scheduled payments of principal and interest due on
or before the Cut-off Date and collected after the Cut-off Date, shall belong to
the Seller. In addition to the sale of the Mortgage Loans, the Seller will cause
the Cap Contracts to be transferred to the Purchaser.

                  SECTION 2. MORTGAGE LOAN SCHEDULE AND PREPAYMENT CHARGE
SCHEDULE. The Purchaser and the Seller have agreed upon which of the mortgage
loans owned by the Seller are to be purchased by the Purchaser pursuant to this
Agreement, and the Seller shall prepare or

<PAGE>

                                       -2-

cause to be prepared on or prior to the Closing Date a final schedule (the
"Closing Schedule") describing such Mortgage Loans and setting forth all of the
Mortgage Loans to be purchased under this Agreement. The Closing Schedule shall
conform to the requirements set forth in this Agreement and to the definition of
"Mortgage Loan Schedule" under the Pooling and Servicing Agreement. The Closing
Schedule shall be used as the Mortgage Loan Schedule under the Pooling and
Servicing Agreement. The Seller shall also prepare or cause to be prepared on or
prior to the Closing Date a final schedule (the "Prepayment Charge Schedule")
setting forth each Mortgage Loan containing a Prepayment Charge and conforming
to the definition of Prepayment Charge Schedule under the Pooling and Servicing
Agreement.

                  SECTION 3.        CONSIDERATION.

                           (a) In consideration for the Mortgage Loans to be
purchased hereunder, the Purchaser shall, as described in Section 8, (i) pay to
or upon the order of the Seller in immediately available funds an amount equal

Certificates, the Class A-3 Certificates, the Class A-4 Certificates, the Class
A-5 Certificates, the Class M-1 Certificates, the Class M-2 Certificates, the
Class M-3 Certificates, the Class M-4 Certificates, the Class M-5 Certificates,

                  SECTION 4.        TRANSFER OF THE MORTGAGE LOANS.

                           (a) POSSESSION OF MORTGAGE FILES. The Seller does
hereby sell to the Purchaser, without recourse but subject to the terms of this
Agreement, all of its right, title and interest in, to and under the Mortgage
Loans, including the related Prepayment Charges collected after the Cut-off
Date. The contents of each Mortgage File not delivered to the Purchaser or to
any assignee, transferee or designee of the Purchaser on or prior to the Closing
Date are and shall be held in trust by the Seller for the benefit of the
Purchaser or any assignee, transferee or designee of the Purchaser. Upon the
sale and contribution of the Mortgage Loans the ownership of each Mortgage Note,
the related Mortgage and the other contents of the related Mortgage File is
vested in the Purchaser and the ownership of all records and documents with
respect to the related Mortgage Loan prepared by or that come into the
possession of the Seller on or after the Closing Date shall immediately vest in
the Purchaser and shall be delivered immediately to the Purchaser or as
otherwise directed by the Purchaser.

                           (b) DELIVERY OF MORTGAGE LOAN DOCUMENTS. The Seller
will, on or prior to the Closing Date, deliver or cause to be delivered to the
Purchaser or any assignee, transferee or designee of the Purchaser each of the

         under the applicable agreement, without recourse," with all prior and
         intervening endorsements showing a complete chain of endorsement from
         the originator to the Person so endorsing to the Trustee, or with
         respect to any lost Mortgage Note, an original Lost Note Affidavit;
         provided, however, that such substitutions of Lost Note Affidavits for
         original Mortgage Notes may occur only with respect to Mortgage Loans,

such Assignment is lost or returned unrecorded because of a defect therein, the
Seller shall promptly prepare or cause to be prepared a substitute Assignment or
cure or cause to be cured such defect, as the case may be, and thereafter cause
each such Assignment to be duly recorded. Notwithstanding the foregoing,
however, for administrative convenience and facilitation of servicing and to
reduce closing costs, the Assignments of Mortgage shall not be required to be
submitted for recording (except with respect to any Mortgage Loan located in
Maryland) unless such failure to record would result in a withdrawal or a
downgrading by any Rating Agency of the rating on any Class of Certificates
(without regard to the Policy); provided further, however, each Assignment of
Mortgage shall be submitted for recording by the Seller (at the direction of the
Master Servicer) in the manner described above, at no expense to the Trust Fund
or the Trustee, upon the earliest to occur of: (i) reasonable direction by
Holders of Certificates entitled to at least 25% of the Voting Rights or the
NIMS Insurer, (ii) a failure of the Master Servicer Termination Test as set
forth in the Pooling and Servicing Agreement, (iii) the occurrence of the
bankruptcy or insolvency of the Seller, (iv) the occurrence of a servicing
transfer as described in Section 7.02 of the Pooling and Servicing Agreement and
(v) if the Seller is not the Master Servicer and with respect to any one
assignment or Mortgage, the occurrence of a bankruptcy, insolvency or
foreclosure relating to the Mortgagor under the related Mortgage.

                  Each original document relating to any Mortgage Loan which is
not delivered to the Purchaser or its assignee, transferee or designee, if held
by the Seller, shall be so held for the benefit of the Purchaser or its
assignee, transferee or designee.

                           (c) ACCEPTANCE OF MORTGAGE LOANS. The documents
delivered pursuant to Section 4(b) hereof shall be reviewed by the Purchaser or
any assignee, transferee or designee of the Purchaser at any time before or
after the Closing Date (and with respect to each document permitted to be
delivered after the Closing Date, within seven (7) days of its delivery) to
ascertain that all required documents have been executed and received and that
such documents relate to the Mortgage Loans identified on the Mortgage Loan

                           (e) TRANSFER OF INTEREST IN AGREEMENTS. The Purchaser
has the right to assign its interest under this Agreement, in whole or in part,
to the Trustee, as may be required to effect the purposes of the Pooling and
Servicing Agreement, without the consent of the Seller, and the assignee shall
succeed to the rights and obligations hereunder of the Purchaser. Any expense
reasonably incurred by or on behalf of the Purchaser or the Trustee in
connection with enforcing any obligations of the Seller under this Agreement
shall be promptly reimbursed by the Seller.

                           (f) EXAMINATION OF MORTGAGE FILES. Prior to the
Closing Date, the Seller shall either (i) deliver in escrow to the Purchaser or
to any assignee, transferee or designee of the Purchaser, for examination, the
Mortgage File pertaining to each Mortgage Loan or (ii) make such Mortgage Files
available to the Purchaser or to any assignee, transferee or designee of the
Purchaser for examination at the Trustee's offices in Santa Ana, California.
Such examination may be made by the Purchaser, and its respective designees,
upon reasonable notice to the Seller and the Trustee during normal business
hours before the Closing Date and within sixty (60) days after the Closing Date.
If any such person makes such examination prior to the Closing Date and
identifies any Mortgage Loans that do not conform to the requirements of the
Purchaser as described in this Agreement, such Mortgage Loans shall be deleted
from the Closing Schedule. The Purchaser may, at its option and without notice
to the Seller, purchase all or part of the Mortgage Loans without conducting any
partial or complete examination. The fact that the Purchaser or any person has
conducted or has failed to conduct any partial or complete examination of the
Mortgage Files shall not affect the rights of the Purchaser or any assignee,
transferee or designee of the Purchaser to demand repurchase or other relief as
provided herein or under the Pooling and Servicing Agreement.

benefits of the security intended to be provided by such Mortgage;

                  (v) Immediately prior to the sale of the Mortgage Loans to the
Purchaser, the Seller had good title to, and was the sole legal and beneficial

(binder) to issue the same was effective on the date of the origination of each
Mortgage Loan, each such policy is valid and remains in full force and effect,

with any and all applicable licensing requirements of the laws of the state
wherein the Mortgaged Property is located;

                  (xviii) The Mortgage Note and the related Mortgage are

security, including (i) in the case of a Mortgage designated as a deed of trust,

the right to foreclose the Mortgage;

                  (xxi) With respect to each Mortgage constituting a deed of

no fees or expenses are or will become payable by the Purchaser to the trustee
under the deed of trust, except in connection with a trustee's sale after
default by the Mortgagor;

                  (xxii) There exist no deficiencies with respect to escrow

connection with the origination of the Group I Mortgage Loan. No proceeds from
any Group I Mortgage Loan were used to purchase single premium credit insurance
policies as part of the origination of, or as a condition to closing, such Group
I Mortgage Loan;

                  (xlix) Each Group I Mortgage Loan is in compliance with the
anti-predatory lending eligibility for purchase requirements of Fannie Mae's
Selling Guide;

                                      -14-

                  (l) The methodology used in underwriting the extension of
credit for each Group I Mortgage Loan employs objective mathematical principles
which relate the Mortgagor's income, assets and liabilities to the proposed
payment and such underwriting methodology does not rely on the extent of the
Mortgagor's equity in the collateral as the principal determining factor in
approving such credit extension. Such underwriting methodology confirmed that at
the time of origination (application/approval) the Mortgagor had a reasonable
ability to make timely payments on the Group I Mortgage Loan;

                  (li) With respect to any Group I Mortgage Loan that contains a
provision permitting imposition of a charge upon a prepayment prior to maturity:
(i) prior to the Group I Mortgage Loan's origination, the Mortgagor agreed to
such charge in exchange for a monetary benefit, including but not limited to a
rate or fee reduction, (ii) prior to the Group I Mortgage Loan's origination,
the Mortgagor was offered the option of obtaining a mortgage loan that did not
require payment of such a charge, (iii) the prepayment charge is disclosed to
the Mortgagor in the loan documents pursuant to applicable state and federal
law, (iv) the duration of the prepayment period shall not exceed three (3) years
from the date of the Mortgage Note if the Mortgage Loan was originated on or
after September 1, 2004, unless the loan was modified to reduce the prepayment
period to no more than three years from the date of the Mortgage Note and the
borrower was notified in writing of such reduction in the prepayment period, and
(v) notwithstanding any state or federal law to the contrary, the Master
Servicer shall not impose such prepayment charge in any instance when the
mortgage debt is accelerated as the result of the Mortgagor's default in making
the loan payments;

                  (lii) All points and fees related to each Group I Mortgage
Loan were disclosed in writing to the Mortgagor in accordance with applicable
state and federal law and regulation. Except in the case of a Group I Mortgage
Loan in an original principal amount of less than $60,000 which would have
resulted in an unprofitable origination, no Mortgagor was charged "points and
fees" (whether or not financed) in an amount greater than 5% of the principal
amount of such loan and such 5% limitation is calculated in accordance with
Fannie Mae's anti-predatory lending requirements as set forth in the Fannie Mae
Selling Guide;

                  (liii) All fees and charges (including finance charges) and
whether or not financed, assessed, collected or to be collected in connection
with the origination and servicing of each Group I Mortgage Loan haves been
disclosed in writing to the Mortgagor in accordance with applicable state and
federal law and regulation;

                  (liv) No Group I Mortgage Loan Mortgagor was encouraged or
required to select a mortgage loan product offered by the Originator which is a
higher cost product designed for a less creditworthy Mortgagor, unless at the
time of the Mortgage Loan's origination, such Mortgagor did not qualify taking
into account credit history and debt to income ratios for a lower cost credit
product then offered by the Originator;

                                      -15-

                  (lv) The Master Servicer will transmit full-file credit
reporting data for each Group I Mortgage Loan pursuant to Fannie Mae Guide
Announcement 95-19 and that for each Group I Mortgage Loan, the Master Servicer
agrees it shall report one of the following statuses each month as follows: new
origination, current, delinquent (30-, 60-, 90-days, etc.), foreclosed, or
charged-off;

                  (lvi) No Mortgage Loan is a "High Cost Home Loan" as defined
in New York Banking Law 6-1;

                  (lvii) No Mortgage Loan is a "High-Cost Home Loan" as defined
under the Arkansas Home Loan Protection Act, effective as of July 14, 2003;

                  (lviii) No Mortgage Loan is a "High-Cost Home Loan" as defined
under Kentucky State Statute KRS 360.100, effective as of June 25, 2003;

                  (lix) No Mortgage Loan is a "High-Cost Home Loan" as defined
in the New Jersey Home Ownership Act, effective as of November 27, 2003;

                  (lx) No Mortgage Loan is a "High-Cost Home Loan" as defined in
the New Mexico Home Loan Protection Act, effective as of January 1, 2004;

                  (lxi) No Mortgage Loan is a "High-Risk Home Loan" as defined
in the Illinois High-Risk Home Loan Act, effective as of January 1, 2004;

                  SECTION 7. REPURCHASE OBLIGATION FOR DEFECTIVE DOCUMENTATION
                             AND FOR BREACH OF REPRESENTATION AND WARRANTY.

                  (a) The representations and warranties contained in Section 6
shall not be impaired by any review and examination of loan files or other
documents evidencing or relating to the Mortgage Loans or any failure on the
part of the Purchaser to review or examine such documents and shall inure to the
benefit of any assignee, transferee or designee of the Purchaser, including the
Trustee for the benefit of the Certificateholders.

                  Upon discovery by the Seller, the Purchaser or any assignee,
transferee or designee of the Purchaser of any materially defective document in,
or that any material document was not transferred by the Seller (as listed on
the Trustee's Preliminary Exception Report) as part of, any Mortgage File or of
a breach of any of the representations and warranties contained in Section 5 or
Section 6 that materially and adversely affects the value of any Mortgage Loan
or the interest therein of the Purchaser or the Purchaser's assignee, transferee
or designee (it being understood that with respect to the representations and
warranties set forth in (xxxix), (xl), (xli), (xlii), (xliv) and (xlv) of
Section 6 herein, a breach of any such representation or warranty shall in and
of itself be deemed to materially adversely affect the interest therein of the
Purchaser and the Purchaser's assignee, transferee or designee), the party
discovering the

<PAGE>

                                      -16-

breach shall give prompt written notice to the others. Within ninety (90) days
of its discovery or its receipt of notice of any such missing documentation
which was not transferred to the Purchaser as described above or materially
defective documentation or any such breach of a representation and warranty (it
being understood that with respect to the representations and warranties set
forth in (xxxix), (xl), (xli), (xlii), (xliv) and (xlv) of Section 6 herein, a
breach of any such representation or warranty shall in and of itself be deemed
to materially adversely affect the interest therein of the Purchaser and the
Purchaser's assignee, transferee or designee), the Seller promptly shall deliver
such missing document or cure such defect or breach in all material respects, or
in the event the Seller cannot deliver such missing document or such defect or
breach cannot be cured, the Seller shall, within ninety (90) days of its
discovery or receipt of notice, either (i) repurchase the affected Mortgage Loan
at a price equal to the Purchase Price or (ii) pursuant to the provisions of the
Pooling and Servicing Agreement, cause the removal of such Mortgage Loan from
the Trust Fund and substitute one or more Qualified Substitute Mortgage Loans.
In the event that any Mortgage Loan is subject to a breach of the representation
and warranty in Section 6(xxxvii) resulting in the Master Servicer's inability
to collect all or part of the Prepayment Charge from the Mortgagor, in lieu of
repurchase, the Seller shall be obligated to remit to the Master Servicer (for
deposit in the Collection Account) any shortfall in the Prepayment Charge
collected upon the Mortgagor's voluntary Principal Prepayment.

                  Notwithstanding the foregoing, within ninety (90) days of the
earlier of discovery by the Seller or receipt of notice by the Seller of the
breach of the representation of the Seller set forth in Section 6(xxxvii) above,
which materially and adversely affects the interests of the Holders of the Class
P Certificates in any Prepayment Charge, the Seller shall pay the amount of the
scheduled Prepayment Charge, for the benefit of the Holders of the Class P
Certificates, by depositing such amount into the Collection Account, net of any
amount previously collected by the Master Servicer and paid by the Master
Servicer, for the benefit of the Holders of the Class P Certificates, in respect
of such Prepayment Charge.

                  The Seller shall amend the Closing Schedule to reflect the
withdrawal of such Mortgage Loan from the terms of this Agreement and the
Pooling and Servicing Agreement and the addition, if any, of a Qualified
Substitute Mortgage Loan. The Seller shall deliver to the Purchaser such amended
Closing Schedule and shall deliver such other documents as are required by this
Agreement or the Pooling and Servicing Agreement within five (5) days of any
such amendment. Any repurchase pursuant to this Section 7(a) shall be
accomplished by deposit in the Collection Account of the amount of the Purchase
Price in accordance with Section 2.03 of the Pooling and Servicing Agreement.
Any repurchase or substitution required by this Section shall be made in a
manner consistent with Section 2.03 of the Pooling and Servicing Agreement.

                  In addition, upon discovery by the Seller, the Purchaser, or
any assignee, transferee or designee of the Purchaser that any Mortgage Loan
does not constitute a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code, the party discovering the

<PAGE>

                                      -17-

breach shall give prompt written notice within five (5) Business Days to the
others. Within ninety (90) days of its discovery or its receipt of notice, the
Seller promptly shall either (i) repurchase the affected Mortgage Loan at the
Purchase Price (as such term is defined in the Pooling and Servicing Agreement)
or (ii) pursuant to the provisions of the Pooling and Servicing Agreement, cause
the removal of such Mortgage Loan from the Trust Fund and substitute one or more
Qualified Substitute Mortgage Loans.

                  (b) It is understood and agreed that the obligations of the
Seller set forth in this Section 7 to cure, remit a Prepayment Charge shortfall,
repurchase or substitute for a defective Mortgage Loan constitute the sole
remedies of the Purchaser against the Seller respecting a missing or defective
material document or a breach of the representations and warranties contained in
Section 5 or Section 6.

                  SECTION 8. CLOSING; PAYMENT FOR THE MORTGAGE LOANS. The
closing of the purchase and sale of the Mortgage Loans shall be held at the New
York City office of Thacher Proffitt & Wood LLP at 10:00 AM New York City time
on the Closing Date.

                  The closing shall be subject to each of the following

                  (a)      All of the representations and warranties of the

                           they are made and no event shall have occurred which,
                           with notice or the passage of time, would constitute
                           a default under this Agreement;

                  (b)      The Purchaser shall have received, or the attorneys
                           of the Purchaser shall have received in escrow (to be
                           released from escrow at the time of closing), all

                           pursuant to the respective terms thereof;

                  (c)      The Seller shall have delivered or caused to be
                           delivered and released to the Purchaser or to its
                           designee, all documents (including without
                           limitation, the Mortgage Loans) required to be so

                           of the Pooling and Servicing Agreement; and

                  (d)      All other terms and conditions of this Agreement
                           shall have been complied with.

                  Subject to the foregoing conditions, the Purchaser shall

                  SECTION 12.       RESERVED.

                  SECTION 13. MANDATORY DELIVERY; GRANT OF SECURITY INTEREST.
The sale and delivery on the Closing Date of the Mortgage Loans described on the
Mortgage Loan Schedule in accordance with the terms and conditions of this
Agreement is mandatory. It is specifically understood and agreed that each
Mortgage Loan is unique and identifiable on the date hereof and that an award of
money damages would be insufficient to compensate the Purchaser for the losses
and damages incurred by the Purchaser in the event of the Seller's failure to
deliver the Mortgage Loans on or before the Closing Date. The Seller hereby
grants to the Purchaser a lien on and a continuing security interest in the
Seller's interest in each Mortgage Loan and each document and instrument
evidencing each such Mortgage Loan to secure the performance by the Seller of
its obligation hereunder, and the Seller agrees that it holds such Mortgage
Loans in custody for the Purchaser, subject to the Purchaser's (i) right, prior
to the Closing Date, to reject any Mortgage Loan to the extent permitted by this
Agreement and (ii) obligation to deliver or cause to be delivered the
consideration for the Mortgage Loans pursuant to Section 8 hereof. Any Mortgage
Loans rejected by the Purchaser shall concurrently therewith be released from
the security interest created hereby. The Seller agrees that, upon acceptance of
the Mortgage Loans by the Purchaser or its designee and delivery of payment to
the Seller, that its security interest in the Mortgage Loans shall be released.
All rights and remedies of the Purchaser under this Agreement are distinct from,
and cumulative with, any other rights or remedies under this Agreement or
afforded by law or equity and all such rights and remedies may be exercised
concurrently, independently or successively.

                  Notwithstanding the foregoing, if on the Closing Date, each of
the conditions set forth in Section 8 hereof shall have been satisfied and the
Purchaser shall not have paid or caused to be paid the Purchase Price, or any
such condition shall not have been waived or satisfied and the Purchaser
determines not to pay or cause to be paid the Purchase Price, the Purchaser
shall immediately effect the redelivery of the Mortgage Loans, if delivery to
the Purchaser has occurred and the security interest created by this Section 13
shall be deemed to have been released.

                  SECTION 14. NOTICES. All demands, notices and communications
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered to or mailed by registered mail, postage prepaid, or
transmitted by telex or telegraph and confirmed by a similar mailed writing, if
to the Purchaser, addressed to the Purchaser at 1100 Town & Country Road, Suite
1100, Orange, California 92868, Facsimile: (714) 564-9639, Attention: General
Counsel, or such other address as may hereafter be furnished to the Seller in

shall be ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof. Any part, provision,
representation or warranty of this Agreement which is prohibited or

as to such jurisdiction, be ineffective to the extent of such prohibition or

                  SECTION 16. AGREEMENT OF PARTIES. The Seller and the Purchaser
agree to execute and deliver such instruments and take such actions as either of
the others may, from time to time, reasonably request in order to effectuate the

                  SECTION 17. SURVIVAL. The Seller agrees that the

warranties and agreements made by the Seller herein or in any such certificate

                  SECTION 18. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS,

THAT THE PROVISIONS OF SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW
SHALL APPLY TO THIS AGREEMENT.

                  SECTION 19. MISCELLANEOUS. This Agreement may be executed in
two or more counterparts, each of which when so executed and delivered shall be
an original, but all of which together shall constitute one and the same
instrument. This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective successors and assigns. This Agreement
supersedes all prior agreements and understandings relating to the subject
matter hereof. Neither this Agreement nor any term hereof may be changed,
waived, discharged or terminated orally, but only by an instrument in writing
signed by the party against whom enforcement of the change, waiver, discharge or
termination is sought. The headings in this Agreement are for purposes of

<PAGE>

                                      -22-

hereof. Each of the NIMS Insurer, if any, and the Certificate Insurer, shall be
a third party beneficiary hereof and may enforce the terms hereof as if a party
hereto.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Seller to the Purchaser as provided in
Section 4 hereof be, and be construed as, a sale of the Mortgage Loans by the
Seller to the Purchaser and not as a pledge of the Mortgage Loans by the Seller
to the Purchaser to secure a debt or other obligation of the Seller. However, in
the event that, notwithstanding the aforementioned intent of the parties, the
Mortgage Loans are held to be property of the Seller, then, (a) it is the
express intent of the parties that such conveyance be deemed a pledge of the
Mortgage Loans by the Seller to the Purchaser to secure a debt or other
obligation of the Seller and (b) (1) this Agreement shall also be deemed to be a
security agreement within the meaning of Articles 8 and 9 of the New York
Uniform Commercial Code; (2) the conveyance provided for in Section 4 hereof
shall be deemed to be a grant by the Seller to the Purchaser of a security
interest in all of the Seller's right, title and interest in and to the Mortgage
Loans and all amounts payable to the holders of the Mortgage Loans in accordance
with the terms thereof and all proceeds of the conversion, voluntary or
involuntary, of the foregoing into cash, instruments, securities or other
property, including without limitation all amounts, other than investment
earnings, from time to time held or invested in the Collection Account whether
in the form of cash, instruments, securities or other property; (3) the
possession by the Purchaser or its agent of Mortgage Notes, the related
Mortgages and such other items of property that constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession" for
purposes of perfecting the security interest pursuant to the New York Uniform
Commercial Code; and (4) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the
Purchaser for the purpose of perfecting such security interest under applicable
law. Any assignment of the interest of the Purchaser pursuant to Section 4(d)
hereof shall also be deemed to be an assignment of any security interest created
hereby. The Seller and the Purchaser 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 Mortgage Loans, 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 this Agreement and the Pooling and Servicing Agreement.

                  IN WITNESS WHEREOF, the Seller and the Purchaser have caused
their names to be signed by their respective officers thereunto duly authorized
as of the date first above written.

                                                    F-Annex-1-4

<PAGE>

the Transferee for the account of a third party (including any separate account)
in reliance on Rule 144A, the Transferee will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third

means two or more registered investment companies (or series thereof) that have
the same investment adviser or investment advisers that are affiliated (by
virtue of being majority owned subsidiaries of the same parent or because one
investment adviser is a majority owned subsidiary of the other).

                  4. The term "Securities" as used herein does not include (i)
securities of issuers that are affiliated with the Transferee or are part of the
Transferee's Family of Investment Companies, (ii) securities issued or
guaranteed by the U.S. or any instrumentality thereof, (iii) bank deposit notes

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF NEW YORK            )
                             : ss.:
COUNTY OF NEW YORK           )

                  ____________________________, being duly sworn, deposes,
represents and warrants as follows:

                  1. I am a ______________________ of __________________________
(the "Owner") a corporation duly organized and existing under the laws of
______________, the record owner of Ameriquest Mortgage Securities Inc.,
Asset-Backed Pass-Through Certificates, Series 2004-R8, Class R (the "Class R
Certificates"), on behalf of whom I make this affidavit and agreement.
Capitalized terms used but not defined herein have the respective meanings
assigned thereto in the Pooling and Servicing Agreement pursuant to which the
Class R Certificates were issued.

                  2. The Owner (i) is and will be a "Permitted Transferee" as of
____________________, 2004 and (ii) is acquiring the Class R Certificates for
its own account or for the account of another Owner from which it has received
an affidavit in substantially the same form as this affidavit. A "Permitted
Transferee" is any person other than a "disqualified organization" or a
possession of the United States. For this purpose, a "disqualified organization"
means the United States, any state or political subdivision thereof, any agency
or instrumentality of any of the foregoing (other than an instrumentality all of
the activities of which are subject to tax and, except for the Federal Home Loan
Mortgage Corporation, a majority of whose board of directors is not selected by
any such governmental entity) or any foreign government, international
organization or any agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any organization
(other than certain farmers' cooperatives) that is generally exempt from federal
income tax unless such organization is subject to the tax on unrelated business
taxable income.

                  3. The Owner is aware (i) of the tax that would be imposed on
transfers of the Class R Certificates to disqualified organizations under the
Internal Revenue Code of 1986, as amended, that applies to all transfers of the
Class R Certificates after March 31, 1988; (ii) that such tax would be on the
transferor or, if such transfer is through an agent (which person includes a
broker, nominee or middleman) for a non-Permitted Transferee, on the agent;
(iii) that the person otherwise liable for the tax shall be relieved of
liability for the tax if the transferee furnishes to such person an affidavit
that the transferee is a Permitted Transferee and, at the time of transfer, such
person does not have actual knowledge that the affidavit is false; and (iv) that
each of the Class R Certificates may be a "noneconomic residual interest" within
the meaning of proposed Treasury regulations promulgated under the Code and that
the transferor of a "noneconomic residual interest" will remain liable for any
taxes due with respect to the income on such residual interest, unless no
significant purpose of the transfer is to impede the assessment or collection of
tax.

                  4. The Owner is aware of the tax imposed on a "pass-through
entity" holding the

                                      F-2-1

<PAGE>

Class R Certificates if, at any time during the taxable year of the pass-through
entity, a non-Permitted Transferee is the record holder of an interest in such
entity. (For this purpose, a "pass-through entity" includes a regulated
investment company, a real estate investment trust or common trust fund, a
partnership, trust or estate, and certain cooperatives.)

                  5. The Owner is aware that the Certificate Registrar will not
register the transfer of any Class R Certificate unless the transferee, or the
transferee's agent, delivers to the Certificate Registrar, among other things,
an affidavit in substantially the same form as this affidavit. The Owner
expressly agrees that it will not consummate any such transfer if it knows or
believes that any of the representations contained in such affidavit and
agreement are false.

                  6. The Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificates will only be
owned, directly or indirectly, by an Owner that is a Permitted Transferee.

                  7. The Owner's taxpayer identification number is ____________.

                  8. The Owner has reviewed the restrictions set forth on the
face of the Class R Certificates and the provisions of Section 5.02(d) of the
Pooling and Servicing Agreement under which the Class R Certificates were issued
(in particular, clauses (iii)(A) and (iii)(B) of Section 5.02(d) which authorize
the Trustee to deliver payments to a person other than the Owner and negotiate a
mandatory sale by the Trustee in the event that the Owner holds such Certificate
in violation of Section 5.02(d)); and that the Owner expressly agrees to be
bound by and to comply with such restrictions and provisions.

                  9. The Owner is not acquiring and will not transfer the Class
R Certificates in order to impede the assessment or collection of any tax.

                  10. The Owner anticipates that it will, so long as it holds
the Class R Certificates, have sufficient assets to pay any taxes owed by the
holder of such Class R Certificates, and hereby represents to and for the
benefit of the person from whom it acquired the Class R Certificates that the
Owner intends to pay taxes associated with holding such Class R Certificates as
they become due, fully understanding that it may incur tax liabilities in excess
of any cash flows generated by the Class R Certificates.

                  11. The Owner has no present knowledge that it may become
insolvent or subject to a bankruptcy proceeding for so long as it holds the
Class R Certificates.

                  12. The Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding.

                  13. The Owner is not acquiring the Class R Certificates with
the intent to transfer the Class R Certificates to any person or entity that
will not have sufficient assets to pay any taxes owed by the holder of such
Class R Certificates, or that may become insolvent or subject to a bankruptcy
proceeding, for so long as the Class R Certificates remain outstanding.

<PAGE>

                  14. The Owner will, in connection with any transfer that it
makes of the Class R Certificates, obtain from its transferee the
representations required by Section 5.02(d) of the Pooling and Servicing
Agreement under which the Class R Certificate were issued and will not
consummate any such transfer if it knows, or knows facts that should lead it to
believe, that any such representations are false.

                  15. The Owner will, in connection with any transfer that it
makes of the Class R Certificates, deliver to the Certificate Registrar an
affidavit, which represents and warrants that it is not transferring the Class R
Certificates to impede the assessment or collection of any tax and that it has
no actual knowledge that the proposed transferee: (i) has insufficient assets to
pay any taxes owed by such transferee as holder of the Class R Certificates;
(ii) may become insolvent or subject to a bankruptcy proceeding for so long as
the Class R Certificates remains outstanding; and (iii) is not a "Permitted
Transferee".

                  16. The Owner is a citizen or resident of the United States, a
corporation or partnership (or other entity treated as a corporation or
partnership for federal income tax purposes) created or organized in, or under
the laws of, the United States, any state thereof or the District of Columbia
(except, in the case of a partnership or entity treated as a partnership, to the
extent provided in regulations), an estate the income of which is subject to
United States federal income taxation regardless of its source or a trust other
than a "foreign trust" described in section 7701(a)(31) of the Code.

duly organized and existing under the laws of ______________, on behalf of whom
I make this affidavit.

                  2. The Owner is not transferring the Class R (the "Residual
Certificates") to impede the assessment or collection of any tax.

                  3. The Owner has no actual knowledge that the Person that is
the proposed transferee (the "Purchaser") of the Residual Certificates: (i) has
insufficient assets to pay any taxes owed by such proposed transferee as holder
of the Residual Certificates; (ii) may become insolvent or subject to a
bankruptcy proceeding for so long as the Residual Certificates remain
outstanding and (iii) is not a Permitted Transferee.

                  4. The Owner understands that the Purchaser has delivered to
the Certificate Registrar a transfer affidavit and agreement in the form
attached to the Pooling and Servicing Agreement as Exhibit F-2. The Owner does
not know or believe that any representation contained therein is false.

                  5. At the time of transfer, the Owner has conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E- 1(c)(4)(i) and, as a result
of that investigation, the Owner has determined that the Purchaser has
historically paid its debts as they became due and has found no significant
evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future. The Owner understands that the transfer of a
Residual Certificate may not be respected for United States income tax purposes
(and the Owner may continue to be liable for United States income taxes
associated therewith) unless the Owner has conducted such an investigation.

                  6. Capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Pooling and Servicing Agreement.

--------------------------------------------------------------------------------

         Workouts in the form of either a Forbearance or Loan Modification
require that the Borrower document the existence of a financial hardship leading
to the payment delinquency and document the ability to make the payments
required under the proposed Forbearance or Loan Modification. If the Borrower
fails to meet both of these conditions or the Borrower is uncooperative, a
Disposal Loss Mitigation Action will be employed to liquidate the delinquent
loan, assuming the Borrower does not otherwise cure the existing default. Each
of the Default Mitigation Actions and Supporting Standards may not be applicable
to each and every loan subject to a default in its monthly payments and in those
cases where a Default Mitigation Action or Supporting Standard may be
applicable, each is subject to amendment and/or waiver on an individual basis
pursuant to applicable federal, state and local laws, decisional authorities,
court orders, instructions of regulatory and/or other governmental authorities,
the advice of legal counsel, instructions from the Trustee and changes in the
loan servicing standards.
