                  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 Pre-Funding Accounts, the Interest Coverage Account, the Net WAC
Rate Carryover Reserve Account and any Subsequent Mortgage Loan Interest)
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.

(1)   Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
      regulations, the Distribution Date immediately following the maturity date
      for the Mortgage Loans with the latest maturity date has been designated
      as the "latest possible maturity date" for each Class of Certificates.
(2)   Calculated in accordance with the definition of "Pass-Through Rate"
      herein. With respect to the Class AF-1 Certificates, the Class AF-2
      Certificates, the Class AF-3 Certificates and the Class AF-4 Certificates,
      subject to the Net WAC Pass-Through Rate. With respect to the Class AF-3
      Certificates and the Class AF-4 Certificates, subject to increase as set
      forth in the definition of "Pass-Through Rate" herein.
(3)   The Class S Certificates will not have a Certificate Principal Balance,
      but will receive all amounts distributed to REMIC III Regular Interest
      III-LTS1 and REMIC III Regular Interest III-LTS2.
(4)   The Class CE Certificates will accrue interest at its variable
      Pass-Through Rate on the Notional Amount of the Class CE Certificates
      outstanding from time to time which shall equal the Uncertificated Balance
      of the REMIC III Regular Interests. The Class CE Certificates will not
      accrue interest on its Certificate Principal Balance. The Class CE
      Certificates will also be entitled to Subsequent Mortgage Loan Interest,
      as a right with respect to a component of the Class CE Certificates that
      will not be treated as a REMIC regular interest but rather as separate
      interest strips from the Subsequent Mortgage Loans for a specified period
      of time.
(5)   The Class P Certificates will not accrue interest.

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

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.

                  On or prior to the Closing Date, the Trustee agrees, for the
benefit of the Certificateholders, to execute and deliver (or cause the
Custodian to execute and deliver) to the Depositor 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,
to review (or cause a Custodian on its behalf to review) each Mortgage Note
within 45 days of the Closing Date (or the related Subsequent Transfer Date,
with respect to the Subsequent Mortgage Loans) and to certify in substantially
the form attached hereto as Exhibit C-1 (or cause the Custodian to certify in
the form



                                       76
<PAGE>




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 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 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 Initial Mortgage
Loans and the Subsequent Mortgage Loans. Upon the request of the Master
Servicer, any exception report related to the final 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 and the Master Servicer. In addition, upon the discovery by the
Depositor, the NIMS Insurer, the Master Servicer or the Trustee of a breach of
any of the representations and warranties made by the Originator 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 in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties.

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

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




                                       77
<PAGE>




                  (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 Originator 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, the
Trustee shall promptly notify the Originator, the NIMS Insurer and the Master
Servicer of such defect, missing document or breach and request that the
Originator deliver such missing document or cure such defect or breach within 90
days from the date the Originator was notified of such missing document, defect
or breach, and if the Originator 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 Originator 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 Originator was notified (subject to Section 2.03(d))
of such missing document, defect or breach, if and to the extent that the
Originator 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 Originator the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Originator shall furnish to it
and as shall be necessary to vest in the Originator 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
Originator may cause 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 Originator 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



                                       78
<PAGE>




         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 affects 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,

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
Originator 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 Originator or
the Depositor substitutes a Qualified Substitute Mortgage Loan or Loans, such
substitution shall be effected by the Originator 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



                                       79
<PAGE>




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 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 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 Originator, 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 Originator, 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 and the NIMS 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 and the NIMS Insurer. 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
Originator, the Mortgage Loan Purchase Agreement, including all applicable
representations and warranties thereof.

                  For any month in which the Depositor or the Originator
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 Originator, 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 Originator, as the case may be, the related Mortgage
File or Files and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Depositor or the Originator,
as the case may be, shall deliver to it and as shall be necessary to vest
therein any Deleted Mortgage Loan released pursuant hereto.




                                       80
<PAGE>




                  In addition, the Depositor or the Originator, as the case may
be, shall obtain at its own expense and deliver to the Trustee and the NIMS
Insurer an Opinion of Counsel to the effect that such substitution will not
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
Originator, 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
Originator 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 Originator. 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 Originator, 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
         authorization, execution and delivery thereof by the Depositor and the
         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



                                       81
<PAGE>




         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
         to which the Master Servicer is a party or by which it may be bound, or
         any statute, order or regulation applicable to the Master Servicer of
         any court, regulatory body, administrative agency or governmental body
         having jurisdiction over the Master Servicer; and the Master Servicer
         is not a party to, bound by, or in breach or violation of any indenture
         or other agreement or instrument, or subject to or in violation of any
         statute, order or regulation of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over it,
         which materially and adversely affects or, to the Master Servicer's
         knowledge, would in the future materially and adversely affect, (x) the
         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
         mortgagee pursuant to Section 203 and Section 211 of the National
         Housing Act;

                  (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,
         authorizations or orders, if any, that have been obtained prior to the
         Closing Date;

                  (vii) The information set forth in the Prepayment Charge
         Schedule attached hereto as Schedule 2 (including the prepayment charge
         summary attached thereto) is complete, true and correct in all material
         respects at the date or dates respecting which such information is
         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'



                                       82
<PAGE>




         rights generally and (ii) the collectability thereof may be limited due
         to acceleration in connection with a foreclosure or other involuntary
         payment;

                  (viii) The Master Servicer will not waive any Prepayment
         Charge or part of a Prepayment Charge unless, (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 or (iii) in the Master Servicer's reasonable
         judgment as described in Section 3.01 hereof, (x) such waiver relates
         to a default or a reasonably foreseeable default, (y) such waiver would
         maximize recovery of total proceeds taking into account the value of
         such Prepayment Charge and related Mortgage Loan and (z) doing so is
         standard and customary in servicing similar Mortgage Loans (including
         any waiver of a Prepayment Charge in connection with a refinancing of a
         Mortgage Loan that is related to a default or a reasonably foreseeable
         default). In no event will the Master Servicer waive a Prepayment
         Charge in connection with a refinancing of a Mortgage Loan that is not
         related to a default or a reasonably foreseeable default;

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

                  (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; and

                  (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.

                  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 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

                          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 (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 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, (4) 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 Property held by the Trust Fund



                                       89
<PAGE>




and (5) 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" pursuant to the REMIC
         Provisions, or (iii) both (x) effect an exchange or reissuance of such



                                       90
<PAGE>




         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 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

liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances

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

                  The foregoing requirements for deposit to the Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, payments in the nature of late payment
charges, assumption fees, insufficient funds charges, modification fees and

clause (2) of the definition thereof to amounts that may be withdrawn from the
Distribution Account) for the related Distribution Date then on deposit in the
Collection Account, (ii) without duplication, the amount of all Prepayment
Charges collected by the Master Servicer, all Prepayment Charges payable by the

         the extent not recoverable under Section 3.05(a)(ii) and (b) any unpaid

         Section 3.16(a) all amounts received thereon subsequent to the date of
         purchase or substitution, as the case may be;

                  (xi) to transfer funds in the Collection Account maintained at

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

(iii), (iv), (v), (vi), (vii), (viii) and (xi) above. The Master Servicer shall
provide written notification to the Trustee and the NIMS Insurer on or prior to
the next succeeding Master Servicer Reporting Date, upon making any withdrawals

time, withdraw from the Escrow Account for the following purposes:

                  (i) to effect payments of ground rents, taxes, assessments,
         water rates, hazard insurance premiums and comparable items;

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

         thereunder;

                  (iii) to refund to the Mortgagor any funds as may be
         determined to be overages;

                  (v) for application to restoration or repair of the Mortgaged

                  (vi) to pay to the Master Servicer, or to the Mortgagor to the

                  (vii) to clear and terminate the Escrow Account on the
         termination of this Agreement; and

                  (viii) to transfer to the Collection Account any Insurance
         Proceeds.

                  In the event the Master Servicer shall deposit in an Escrow
Account any amount not required to be deposited therein, it may at any time
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 funds in the Escrow
Account, to the extent such action is in conformity with the Servicing Standard,
is permitted by law and such amounts are not required to be paid to Mortgagors
or used for any of the other purposes set forth above.

                  (c) Distribution Account. The Trustee shall, from time to

                  (i) to make distributions to Certificateholders in accordance
         with Section 4.01;

                  (ii) to pay to itself and the Trustee amounts to which it is
         entitled pursuant to Section 8.05;

                  (iii) to pay itself any interest income earned on funds
         deposited in the Distribution Account pursuant to Section 3.06;

                  (iv) to reimburse itself pursuant to Section 7.01 and Section
         7.02(b);

                  (v) to pay any amounts in respect of taxes pursuant to Section

         to Section 9.01.

                  SECTION 3.06. Investment of Funds in the Collection Account,
                                the Escrow Account, the REO Account and the
                                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
with any document of transfer necessary to transfer title to such investment to
the Trustee or its nominee. In the event amounts on deposit in an Investment
Account are at any time invested in a Permitted Investment payable on demand,
the Trustee shall:

                  (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 Pre-Funding Accounts, the Interest
Coverage Account and 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 4.07 (with respect to the Pre-Funding
Accounts), Section 4.08 (with respect to the Interest Coverage Account) and
Section 4.10 (with respect to the Net WAC Rate Carryover Reserve Account) 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.

                  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



                                      100
<PAGE>




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
Stated 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 Stated 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 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



                                      101
<PAGE>




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 and 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 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.

                  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



                                      102
<PAGE>




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



                                      103
<PAGE>




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 NIMS Insurer.

                  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



                                      104
<PAGE>




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. 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. 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 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 and the Depositor an Opinion of Counsel, addressed to the
Trustee, the NIMS 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



                                      105
<PAGE>




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 (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.

                  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:




                                      106
<PAGE>




                  (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 and the NIMS 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 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 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.




                                      107
<PAGE>




                  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 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



                                      108
<PAGE>




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 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



                                      109
<PAGE>




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.

                  (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.




                                      110
<PAGE>




                  (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 Depositor and each Rating Agency on or before March 15th of each
calendar year commencing in 2004, an Officers' Certificate stating, as to each
signatory thereof, that (i) a review of the activities of the Master Servicer
during the preceding 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
2004, 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 fiscal 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 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 Servicer designated by it. In addition,
access to the documentation regarding the Mortgage Loans will be provided to any
Certificateholder, Certificate Owner, the Trustee, the NIMS 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. [Reserved].

                  SECTION 3.23. Advance Facility.



                                      112
<PAGE>




                  (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 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 advancing 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.




                                      113
<PAGE>




                  (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 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.

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 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



                                      130

               (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, the Trustee shall pay to UBS Warburg LLC 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 to 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.

                  (a) On the Master Servicer Reporting Date, the Master Servicer
shall deliver to the Trustee and the NIMS Insurer by telecopy (or by such other
means as the Master Servicer, the Trustee and the NIMS Insurer may agree from
time to time) a Remittance Report with respect to the related Distribution Date.
Such Remittance Report will include (i) the amount of Advances to be made by the

by the Master Servicer.

                  Not later than fifteen days after each Distribution Date, the
Master Servicer shall forward to the Trustee, the NIMS Insurer and the Depositor

Mae Monthly Accounting Report for its Guaranteed Mortgage Pass-Through Program

a prospective transferee of a Certificate, upon request at the expense of the
requesting party, provided such statement is delivered by the Master Servicer to
the Trustee.

                  (b) The amount of Advances to be made by the Master Servicer
for any Distribution Date shall equal, subject to Section 4.03(d), the sum of
(i) the aggregate amount of Monthly Payments (with each interest portion thereof
net of the related Servicing Fee), due on the related Due Date in respect of the
Mortgage Loans, which Monthly Payments were delinquent as of the close of
business on the related Determination Date and (ii) with respect to each REO
Property,



                                      135

and as to which such REO Property an REO Disposition did not occur during the
related Prepayment Period, an amount equal to the excess, if any, of the Monthly
Payments (with each interest portion thereof net of the related Servicing Fee)
that would have been due on the related Due Date in respect of the related
Mortgage Loans, over the net income from such REO Property transferred to the
Distribution Account pursuant to Section 3.13 for distribution on such
Distribution Date.

                  On or before 3:00 p.m. New York time on the Master Servicer
Remittance Date, the Master Servicer shall remit in immediately available funds
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 or (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 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 a
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 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,
shall continue until a Final Recovery Determination in connection therewith or
the removal thereof from REMIC I pursuant to any applicable provision of this
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, shall be evidenced by an Officers' Certificate
of the Master Servicer delivered to the Trustee and the NIMS Insurer.

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 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, to Net

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. All references above to the Certificate
Principal Balance of any Class of Certificates shall be to the Certificate
Principal Balance of such Class immediately prior to the relevant Distribution
Date, before reduction thereof by any Realized Losses, in each case to be
allocated to such Class of Certificates, on such Distribution Date.

<PAGE>




                  Any allocation 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 CE Certificate shall be made by reducing the amount otherwise payable in
respect thereof pursuant to Section 4.01(a)(4)(vii). 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) All Realized Losses on the Group I Mortgage Loans shall be
allocated by the Trustee on each Distribution Date, first to REMIC I Regular
Interest I-LT1 and REMIC I Regular Interest I-LT1PF, until the Uncertificated
Balance of each such REMIC I Regular Interest has been reduced to zero; provided
however, with respect to the first three Distribution Dates, all Realized Losses
on the Initial Group I Mortgage Loans shall be allocated to REMIC 1 Regular
Interest I-LT1, until the Uncertificated Balance thereof has been reduced to
zero, and all Realized Losses on the Subsequent Group I Mortgage Loans shall be
allocated to REMIC I Regular Interest I-LT1PF until the Uncertificated Balance
thereof has been reduced to zero. All Realized Losses on the Group II Mortgage
Loans shall be allocated by the Trustee on each Distribution Date, first to
REMIC I Regular Interest I-LT2 and REMIC I Regular Interest I-LT2PF, until the
Uncertificated Balance of each such REMIC I Regular Interest has been reduced to
zero; provided however, with respect to the first three Distribution Dates, all
Realized Losses on the Initial Group II Mortgage Loans shall be allocated to
REMIC I Regular Interest I-LT2, until the Uncertificated Balance thereof has
been reduced to zero, and all Realized Losses on the Subsequent Group II
Mortgage Loans shall be allocated to REMIC I Regular Interest I-LT2PF until the
Uncertificated Balance thereof has been reduced to zero. All Realized Losses on
the Group III Mortgage Loans shall be allocated by the Trustee on each
Distribution Date, first to REMIC I Regular Interest I-LT3 and REMIC I Regular
Interest I-LT3PF, until the Uncertificated Balance of each such REMIC I Regular
Interest has been reduced to zero; provided however, with respect to the first
three Distribution Dates, all Realized Losses on the Initial Group III Mortgage
Loans shall be allocated to REMIC 1 Regular Interest I- LT3, until the
Uncertificated Balance thereof has been reduced to zero, and all Realized Losses
on the Subsequent Group III Mortgage Loans shall be allocated to REMIC I Regular
Interest I-LT3PF until the Uncertificated Balance thereof has been reduced to
zero. All Realized Losses on the Group IV Mortgage Loans shall be allocated by
the Trustee on each Distribution Date, first to REMIC I Regular Interest I-LT4
and REMIC I Regular Interest I-LT4PF, until the Uncertificated Balance of each
such REMIC I Regular Interest has been reduced to zero; provided however, with
respect to the first three Distribution Dates, all Realized Losses on the
Initial Group IV Mortgage Loans shall be allocated to REMIC I Regular Interest
I-LT4, until the Uncertificated Balance thereof has been reduced to zero, and
all Realized Losses on the Subsequent Group IV Mortgage Loans shall be allocated
to REMIC I Regular Interest I-LT4PF until the Uncertificated Balance thereof has
been reduced to zero.

to the Uncertificated Balances of REMIC III Regular Interest III-LTAA, REMIC III
Regular Interest III-LTM5 and REMIC III Regular Interest III-LTZZ, 98%, 1.00%,
and 1%, respectively, until the Uncertificated Balance of REMIC III Regular
Interest III-LTM5 has been reduced to zero; fifth to the Uncertificated Balances
of REMIC III Regular Interest III-LTAA, REMIC III Regular Interest III-LTM4 and
REMIC III Regular Interest III-LTZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Balance of REMIC III Regular Interest III-LTM4 has been reduced

                  (ii) The REMIC III Sub WAC Allocation Percentage of all

Distribution Date first, so as to keep the Uncertificated 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 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



                                      139
<PAGE>




of Realized Losses shall be applied to such REMIC III Regular Interests such
that the REMIC III Subordinated Balance Ratio is maintained); and third, any
remaining Realized Losses shall be allocated to REMIC III Regular Interest
III-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.

                  (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 Securities and Exchange Commission thereunder, and the Depositor shall
sign (or shall cause another entity acceptable to the Securities and Exchange
Commission to sign) and the Trustee shall file (via the Securities and Exchange
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 Securities and Exchange Commission),
the Trustee shall file a Form 10-K, in substance as required by applicable law
or applicable Securities and Exchange 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.




                                      140

                  (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, 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 Securities and Exchange
Commission, the Trustee shall promptly deliver to the Depositor a copy of any
executed report, statement or information.

                  (e) Prior to January 30 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. Pre-Funding Accounts.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain four segregated trust accounts that are each Eligible
Accounts, which shall be titled (i) "Group I Pre- Funding Account, Deutsche Bank
National Trust Company, as Trustee for the registered holders of



                                      141
<PAGE>




Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through Certificates,
Series 2003-6" (the "Group I Pre-Funding Account"); (ii) "Group II Pre-Funding
Account, Deutsche Bank National Trust Company, as Trustee for the registered
holders of Ameriquest Mortgage Securities Inc., Asset- Backed Pass-Through
Certificates, Series 2003-6" (the "Group II Pre-Funding Account"); (iii) "Group
III Pre-Funding Account, Deutsche Bank National Trust Company, as Trustee for
the registered holders of Ameriquest Mortgage Securities Inc., Asset-Backed
Pass-Through Certificates, Series 2003-6" (the "Group III Pre-Funding Account");
and (iv) "Group IV Pre-Funding Account, Deutsche Bank National Trust Company, as
Trustee for the registered holders of Ameriquest Mortgage Securities Inc.,
Asset-Backed Pass-Through Certificates, Series 2003-6" (the "Group IV
Pre-Funding Account"). The Trustee shall, promptly upon receipt, deposit in the
applicable Pre- Funding Account and retain therein the Original Group I
Pre-Funded Amount, the Original Group II Pre-Funding Account, the Original Group
III Pre-Funding Account or the Group IV Pre-Funding Account, as applicable,
remitted on the Closing Date to the Trustee by the Depositor. Funds deposited in
the Pre-Funding Accounts shall be held in trust by the Trustee for the
Certificateholders for the uses and purposes set forth herein.

                  (b) The Trustee shall invest funds deposited in the
Pre-Funding Accounts in Permitted Investments of the kind described in clauses
(i), (v) or (vi) of the definition of Permitted Investments, as directed by the
Master Servicer, with a maturity date no later than the second Business Day
preceding each Distribution Date. For federal income tax purposes, the holder of
the largest Percentage Interest of the Residual Certificates shall be the owner
of the Pre-Funding Accounts and shall report all items of income, deduction,
gain or loss arising therefrom. All income and gain realized from investment of
funds deposited in the Pre-Funding Account shall be transferred to the Interest
Coverage Account (as specified in Section 4.08) on the Business Day immediately
preceding each Distribution Date. The Master Servicer shall deposit in the
Pre-Funding Account the amount of any net loss incurred in respect of any such
Permitted Investment immediately upon realization of such loss without any right
of reimbursement therefor. The Pre-Funding Account will not be an asset of any
Trust REMIC.

                  (c) Amounts on deposit in the Pre-Funding Accounts shall be
withdrawn by the Trustee as follows:

                  (i) on any Subsequent Transfer Date, the Trustee shall
         withdraw from the related Pre-Funding Account an amount equal to 100%
         of the Stated Principal Balances of the Subsequent Mortgage Loans
         transferred and assigned to the Trustee for deposit in the Mortgage
         Pool on such Subsequent Transfer Date and pay such amount to or upon
         the order of the Depositor upon satisfaction of the conditions set
         forth in Section 2.10 with respect to such transfer and assignment;

                  (ii) if the amount on deposit in the related Pre-Funding
         Account has not been reduced to zero during the Funding Period, on the
         day immediately following the termination of the Funding Period, the
         Trustee shall deposit into the Distribution Account any amounts
         remaining in the Pre-Funding Account, net of any gain realized from the
         investment of funds on deposit therein to the extent not previously
         paid to the Interest Coverage Account, for distribution in accordance
         with the terms hereof;




                                      142
<PAGE>




                  (iii) to withdraw any amount not required to be deposited in
         the Pre-Funding Accounts or deposited therein in error;

                  (iv) to distribute to the Interest Coverage Account any income
         and gain realized from the investment of funds in the Pre-Funding
         Accounts; and

                  (v) to clear and terminate the Pre-Funding Accounts upon the
         earlier to occur of (A) the day immediately following the end of the
         Funding Period and (B) the termination of this Agreement, with any
         amounts remaining on deposit therein being paid to the Holders of the
         Certificates then entitled to distributions in respect of principal.

                  SECTION 4.08. Interest Coverage Account.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain a segregated trust account that is an Eligible Account,
which shall be titled "Interest Coverage Account, Deutsche Bank National Trust
Company, as Trustee for the registered holders of Ameriquest Mortgage Securities
Inc., Asset-Backed Pass-Through Certificates, Series 2003-6" (the "Interest
Coverage Account"). The Trustee shall, promptly upon receipt, deposit in the
Interest Coverage Account and retain therein the Interest Coverage Amount,
remitted on the Closing Date to the Trustee by the Depositor. Funds deposited in
the Interest Coverage Account shall be held in trust by the Trustee for the
Certificateholders for the uses and purposes set forth herein

                  (b) The Trustee shall invest funds deposited in the Interest
Coverage Account in Permitted Investments of the kind described in clauses (i),
(v) or (vi) of the definition of Permitted Investments, as directed by the
Master Servicer, with a maturity date no later than the second Business Day
preceding each Distribution Date. For federal income tax purposes, the holder of
the largest Percentage Interest of the Residual Certificates shall be the owner
of the Interest Coverage Account and shall report all items of income,
deduction, gain or loss arising therefrom. At no time will the Interest Coverage
Account be an asset of any Trust REMIC. All income and gain realized from
investment of funds deposited in the Interest Coverage Account shall be for the
sole and exclusive benefit of the Master Servicer and shall be remitted by the
Trustee to the Master Servicer on the first Business Day following each
Distribution Date. The Master Servicer shall deposit in the Interest Coverage
Account the amount of any net loss incurred in respect of any such Permitted
Investment immediately upon realization of such loss.

                  (c) On each Distribution Date during the Funding Period and on
the Distribution Date immediately following the end of the Funding Period, the
Trustee shall withdraw from the Interest Coverage Account and deposit in the
Distribution Account the amount, if any, by which (a) the Interest Distribution
Amount for the Offered Certificates for such Distribution Date exceeds (b) the
actual amount being distributed on the Offered Certificates in respect of
interest (including Interest Carry Forward Amounts) on such Distribution Date.
Such withdrawal and deposit shall be treated as a contribution of cash by the
Master Servicer to REMIC I. Immediately following any such withdrawal and
deposit, and immediately following the conveyance of any Subsequent Mortgage
Loans to the Trust on any Subsequent Transfer Date, the Trustee shall withdraw
from the Interest Coverage Account and remit to the Master Servicer or its
designee an amount equal to the excess, if any, of the amount remaining in the
Interest Coverage Account over the amount that would be



                                      143
<PAGE>




required to be withdrawn therefrom (assuming sufficient funds therein) pursuant
to the second preceding sentence on each subsequent Distribution Date, if any,
that will occur during the Funding Period or that will be the Distribution Date
immediately following the end of the Funding Period, if no Subsequent Mortgage
Loans were acquired by the Trust Fund after the end of the Prepayment Period
relating to the current Distribution Date (assuming that LIBOR remains constant
at the level of LIBOR applicable to the calculation of the Pass-Through Rate for
the A-1 Certificates for the current Distribution Date).

                  (d) Upon the earlier of (i) the Distribution Date immediately
following the end of the Funding Period, (ii) the reduction of the aggregate
Certificate Principal Balance of the Class A Certificates and the Mezzanine
Certificates to zero or (iii) the termination of this Agreement in accordance
with Section 9.01, any amount remaining on deposit in the Interest Coverage
Account after distributions pursuant to paragraph (c) and (d) above shall be
withdrawn by the Trustee and paid to the Depositor or its designee.

                  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 2003-6." On the Closing Date, the Depositor will deposit,
or cause to be deposited, into the Net WAC Rate Carryover Reserve Account
$1,000.

                  (b) On each Distribution Date as to which there is a Net WAC
Rate Carryover Amount payable to the Class A Certificates, the Class S
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,
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, the Class S Certificates and
the Mezzanine Certificates, and will distribute such amounts to the Holders of
the Class A Certificates, the Class S Certificates and the Mezzanine
Certificates in the amounts and priorities set forth in Section 4.01(a). If no
Net WAC Rate Carryover Amounts are payable on a Distribution Date, the Trustee
shall deposit into the Net WAC Rate Carryover Reserve Account on behalf of the
Class CE Certificateholders, from amounts otherwise distributable to the Class
CE Certificateholders, an amount such that when added to other amounts already
on deposit in the Net WAC Rate Carryover Reserve Account, the aggregate amount
on deposit therein is equal to $1,000.

                  (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 (other than the initial deposit therein of $1,000) shall be
treated as amounts distributed by REMIC IV to the Holders of the Class CE
Certificates. Upon the termination of the Trust, or the payment in full of the
Class A Certificates,



                                      144
<PAGE>




the Class S 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, the Class
S 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 tax return and information reporting, the
right of the Holders of the Class A Certificates, the Class S 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 shall be
assigned a value of zero.

                                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-9. 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, the Class S 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 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, (ii) the Depositor at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the Depository
or (iii) 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,
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 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 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 CE Certificate, a Class P Certificate
or a 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 Class R Certificate by the Depositor
to an "accredited investor" within the meaning of Rule 501(d) of the 1933 Act.



                                      148

                  (c) No transfer of a 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 the Trustee is provided with
an Opinion of Counsel for the benefit of the Depositor, the Trustee 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 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 Trustee or the Trust Fund. 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 a 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 in
reliance on the Underwriters' Exemptions, and that it understands that there are
certain conditions to the availability of the Underwriters' Exemptions,
including that the Mezzanine 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) (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 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 paragraph, 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 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 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



                                      149
<PAGE>




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.

                  (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



                                      150
<PAGE>




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, 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:




                                      151
<PAGE>




                  (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 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 four
separate Certificates, each representing such Holder's respective Percentage
Interest in the Class R-I Interest, the Class R-II Interest, the Class R-III
Interest and the Class R-IV 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 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



                                      152
<PAGE>




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 August 2003.

                  (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 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 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 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 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, the Class P
Certificates or the 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



                                      153
<PAGE>




Certificate, originals or copies of the following items: (i) in the case of a
Holder or prospective transferee of a Class CE Certificate, a Class P
Certificate or a 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

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

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.

                                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, the Class S Certificates 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



                                      155
<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 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 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 and written confirmation from
each Rating Agency (which confirmation shall be furnished to the Depositor, the
NIMS Insurer and the Trustee) that such resignation will not cause such Rating
Agency to reduce the then current rating of the Class A Certificates, the Class
S Certificates 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 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 shall have
assumed the Master Servicer's responsibilities, duties,



                                      156
<PAGE>




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
downgrading by any Rating Agency of the ratings on any Class of Certificates and
the NIMS Insurer shall have consented to such Sub-Servicing Agreement) with
Sub-Servicers, for the servicing and administration of the Mortgage Loans.



                                      157
<PAGE>




                  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 relating to insurance 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 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 and the Certificateholders, shall enforce the
obligations of each Sub-Servicer under the related Sub-Servicing Agreement and
of the Originator 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, 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 Originator shall
be effected by the Master Servicer to the extent it is not the Originator, 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 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 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 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
         Originator, the failure of the Originator 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, marshalling 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, marshalling 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




                                      161
<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 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 or a
successor Master Servicer appointed in accordance with Section 7.02, shall
immediately make such Advance 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 otherwise, and
shall continue to be entitled to the benefits of Section 6.03, notwithstanding
any such



                                      162
<PAGE>




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 and 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 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



                                      163
<PAGE>




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 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 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



                                      164
<PAGE>




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 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 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 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



                                      165

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 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.




                                      167
<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



                                      168
<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.

                  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.

                  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



                                      169
<PAGE>




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, 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 Originator, 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 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 Master Servicer and the Certificateholders. Upon receiving such
notice of resignation of the Trustee, the Depositor shall promptly appoint a
successor trustee acceptable to the NIMS Insurer by written instrument, in



                                      170
<PAGE>




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 Trustee and the Master Servicer by the Depositor. 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 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 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 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 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.

                  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 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



                                      171

8.06 and the appointment of such successor trustee shall not result in a
downgrading of any Class of Certificates 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 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 Trustee may consider necessary or desirable. Any such
co-trustee or separate trustee shall be subject to the written approval of the
Master Servicer and the NIMS Insurer. If the Master Servicer 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 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 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 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 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 will 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



                                      173
<PAGE>




agent located c/o DTC Transfer Agent Services, 55 Water Street, Jeanette Park
Entrance, New York, NY 10041 for such purposes.

                  SECTION 8.13. Representations and Warranties of the Trustee.

                  The Trustee hereby represents and warrants, to the Master
Servicer 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.

                  (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 will 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 (in the case of fair market values required to be determined
in 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 all interest accrued on,
as well as amounts necessary to retire the Stated Principal 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.

                  (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 will 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 Mortgage Loans
and each REO Property remaining in the Trust Fund at the time of such election
is less than 10% of the sum of the aggregate Stated Principal Balance of the
Initial Mortgage Loans as of the Cut-off Date and the Original Pre-Funded
Amounts and (B) if the Terminator is the Master Servicer and is an affiliate of
the Originator, the Master Servicer shall have delivered to the Trustee



                                      175
<PAGE>




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 assign and transfer 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 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 will
terminate and final payment in respect of the REMIC I Regular Interests, the
REMIC II Regular Interests and the Certificates will 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 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



                                      176
<PAGE>




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 to UBS Warburg LLC 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.

                  (a) The Trustee shall elect to treat each Trust REMIC as a

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

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

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

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



                                      178
<PAGE>




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 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 and the NIMS Insurer have
received an Opinion of Counsel, addressed to the Trustee (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 will 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 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 will consult with the
Trustee, the NIMS 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 or the NIMS Insurer
has advised it in writing that an Adverse REMIC Event could occur. The Trustee
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



                                      179

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
(in its capacity as Originator) on behalf of the Trustee will ensure that
substantially all of the assets of any Trust REMIC will 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, 2004, the Trustee shall deliver to the Master Servicer, the NIMS
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 will 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 will 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 will 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
REMIC I pursuant to

Article IX of this Agreement, (iv) a substitution pursuant to Article II of this
Agreement or (v) a purchase of Mortgage Loans pursuant to Article II or III of
this Agreement), nor acquire any assets for any Trust REMIC (other than REO
Property acquired in respect of a defaulted Mortgage Loan), 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 will 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 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 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.

                  This Agreement or any Custodial Agreement may be amended from
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
effect to the expectations of Certificateholders), or in any Custodial
Agreement, or (iii) to make any other provisions with respect to matters or
questions arising under this Agreement or in any Custodial Agreement which shall
not be inconsistent with the provisions of this Agreement or such Custodial
Agreement, provided that such action shall not adversely affect in any material
respect the interests of any Certificateholder, as evidenced by either (i) an
Opinion of Counsel delivered to the Master Servicer and the Trustee to such
effect or (ii) confirmation from the Rating Agencies that such amendment will
not result in the reduction or withdrawal of the rating of any outstanding Class
of Certificates. 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
shall (i) reduce in any manner the amount of, or delay the timing of, payments
received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, (ii)
adversely affect in any material respect the interests of the Holders of any
Class of Certificates (as evidenced by either (i) an Opinion of Counsel
delivered to the Trustee or (ii) written notice to the Depositor, the Servicer
and the Trustee from the Rating Agencies that such action will not 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.

                  Notwithstanding any contrary provision of this Agreement,
neither the Trustee nor 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 to the effect that such amendment will 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.




                                      182
<PAGE>




                  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
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.

                  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
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
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

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 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 11.04. Governing Law.

                  This Agreement shall be construed in accordance with the laws
of the State of New York and the obligations, rights and remedies of the parties

                  In addition, the Trustee shall promptly furnish to each Rating
Agency and the NIMS Insurer copies of each report to Certificateholders

<PAGE>




as required pursuant to Section 3.19 and Section 3.20, shall promptly furnish to

                  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 Originator. 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 Originator, then, (a) it is the express intent of the
parties that such conveyance be deemed a pledge of the Mortgage Loans by the
Depositor to the Trustee to secure a debt or other obligation of the Depositor
or the Originator 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 Originator and the Depositor to the Trustee of a security interest in all of
the Originator'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



                                      186
<PAGE>




sentence, for the purpose of securing to the Trustee the performance by the
Depositor of the obliga tions 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.

                  IN WITNESS WHEREOF, the Depositor, the Master Servicer and the
Trustee have caused their names to be signed hereto by their respective officers
thereunto duly authorized, in each case as of the day and year first above
written.

aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off

                  This Certificate is one of a duly authorized issue of

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

such Holder's attorney duly authorized in writing, and thereupon one or more new

aggregate Percentage Interest will be issued to the designated transferee or
transferees.

specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new

                  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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

                  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.

                  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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

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.

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

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

transferees.

aggregate Percentage Interest, as requested by the Holder surrendering the same.

                  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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

                  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

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

herein have the meanings assigned 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 the acceptance
hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be

                  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
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Trustee in writing at

                                     AF-4-2

<PAGE>



Distribution Date on which the aggregate principal balance of the Mortgage Loans
(and properties acquired in respect thereof) remaining in the Trust is reduced
to less than 10% of the sum of the aggregate principal balance of the Initial
Mortgage Loans as of the Cut-off Date and the Original Pre-Funded Amounts, or
4.829% per annum, in the case of any Distribution Date thereafter and (y) the
related Net WAC Pass-Through Rate for such class for such Distribution Date.

                  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 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 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


                                     AF-4-3

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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

                  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.

                  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

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

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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate principal balance of the Initial Mortgage Loans as of the Cut-off Date
and the Original Pre-Funded Amounts.

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

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.

                  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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate principal balance of the Initial Mortgage Loans as of the Cut-off Date
and the Original Pre-Funded Amounts.

                  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.

                  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 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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the aggregate
Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee does not assume any 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.

                  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 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


                                      CE-3

<PAGE>



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 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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

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

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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

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

                      ASSET-BACKED PASS-THROUGH CERTIFICATE

evidencing a beneficial ownership interest in a Trust Fund (the "Trust Fund")

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 GUARANTEED BY ANY AGENCY OR

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,

to be distributed to the Holders of Class R Certificates on such Distribution
Date pursuant to the Agreement.

                  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

specified on the face hereof (herein called the "Certificates") and representing
a Percentage Interest in the Class of Certificates specified on the face


                                       R-3

<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


                                       R-4

<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 to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Loans at the time of purchase being less than 10% of the sum of the
aggregate Stated Principal Balance of the Initial Mortgage Loans at the Cut- off
Date and the Original Pre-Funded Amounts.

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

         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

                  (iii) an original Assignment of the Mortgage assigned in

         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, insuring
         the priority of the Mortgage as a first lien on the Mortgaged Property
         represented therein as a fee interest vested in the Mortgagor, or in

                  If any document referred to in Section 4(b)(ii), 4(b)(iii) or
4(b)(iv) above has 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 Originator hereunder shall be deemed to have been satisfied
upon (1) delivery by or on behalf of the Originator promptly upon receipt
thereof to the Purchaser or any assignee, transferee or designee of the
Purchaser of either the original or a copy of such document certified by the
Originator in the case of (x) above or the public recording office in the case
of (y) above to be a true and complete copy of the recorded original thereof and
(2) if such delivered copy is certified by the Originator then in addition
thereto delivery promptly upon receipt thereof of either the original or a copy
of such document certified by the public recording office to be a true and
complete copy of the original. In the event that the original lender's title
insurance policy has not yet been issued, the Originator shall deliver to the
Purchaser or any assignee, transferee or designee of the Purchaser a written
commitment or interim binder or preliminary report of title issued by the title
insurance or escrow company. Promptly upon receipt by the Originator of any such
original title insurance policy the Originator shall deliver such to the
Purchaser or any assignee, transferee or designee of the Purchaser.

                  The Originator shall promptly (and in no event later than
thirty (30) Business Days, subject to extension upon mutual agreement between
the Originator and the Trustee, following the later of (i) the Closing Date,
(ii) the date on which the Originator receives the Assignment from the Trustee
and (iii) the date of receipt by the Originator 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 (iii) and (iv) above and shall execute
each original Assignment referred to in (iii) in the following form: "Deutsche
Bank National Trust Company, as Trustee under the applicable agreement without
recourse". In the event that any such Assignment is lost or returned unrecorded
because of a defect therein, the Originator 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; provided further, however, each Assignment of
Mortgage shall be submitted for recording by the Originator 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) failure
of the Master Servicer Termination Test, (iii) the occurrence of the bankruptcy
or insolvency of the Originator, (iv) the occurrence of a servicing transfer as
described in Section 7.02 of the Pooling and Servicing Agreement, and (v) if the
Originator 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 a Mortgage Loan which is
not delivered to the Purchaser or its assignee, transferee or designee, if held
by the Originator, 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 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 Schedule.

                           (d) RESERVED.

                           (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 Originator, 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 Originator under this Agreement
will be promptly reimbursed by the Originator.

                           (f) EXAMINATION OF MORTGAGE FILES. Prior to the
Closing Date, the Originator 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 Originator and the Trustee during normal business
hours before the Closing Date and within 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
Originator, 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.

                  SECTION 5. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
                             ORIGINATOR.

                  SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE ORIGINATOR
                             RELATING TO THE MORTGAGE LOANS.

                  (a) The Originator hereby represents and warrants to the
Purchaser, with respect to the Initial Mortgage Loans as of the Closing Date and

Transfer Date or as of such date specifically provided herein:

                           (i) The information set forth on the Mortgage Loan
Schedule with respect to each Mortgage Loan is true and correct in all material
respects;

                           (ii)   [Reserved];

                           (iii) No material error, omission, misrepresentation,
negligence, fraud or similar occurrence with respect to a Mortgage Loan has
taken place on the part of any person, including without limitation, the

been made and none of the Mortgage Loans will have been contractually delinquent
for more than one calendar month more than once since the origination thereof;

lien on the Mortgaged Property, including all improvements thereon, subject only
to (a) the lien of nondelinquent current real property taxes and assessments,

exceptions appearing of record being acceptable to mortgage lending institutions
generally or specifically reflected in the appraisal made in connection with the
origination of the related Mortgage Loan, and (c) other matters to which like

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

                           (vi) Immediately prior to the sale of the Mortgage
Loans to the Purchaser, the Originator had good title to, and was the sole legal
and beneficial owner of, each Mortgage Loan

free and clear of any pledge, lien, encumbrance or security interest and has

agreement with, any other party to sell and assign the same;

                           (vii) There is no delinquent tax or assessment lien
against any Mortgaged Property;

                           (viii) There is no valid offset, defense or
counterclaim to any Mortgage Note or Mortgage, including the obligation of the
Mortgagor to pay the unpaid principal of or interest on such Mortgage Note, nor
will the operation of any of the terms of the Mortgage Note and the Mortgage, or
the exercise of any right thereunder, render the Mortgage unenforceable, in
whole or in part, or subject to any valid right of rescission, set-off,
counterclaim or defense, including the defense of usury and no such valid right
of rescission, set-off, counterclaim or defense has been asserted with respect
thereto;

                           (ix) There are no mechanics' liens or claims for
work, labor or material rendered to the Mortgaged Property affecting any
Mortgaged Property which are or may be a lien prior to, or equal with, the lien

                           (x) Subject to the Escrow Withhold referred to in
(xx) below, each Mortgaged Property is free of material damage and is in good
repair;

                           (xi) Each Mortgage Loan at origination complied in
all material respects with applicable local, state and federal laws, including,
without limitation, usury, equal credit opportunity, real estate settlement
procedures, truth-in-lending, disclosure laws and all applicable predatory and

will not involve the violation of any such laws;

                           (xii) Neither the Originator nor any prior holder of
any Mortgage has modified the Mortgage in any material respect (except that a
Mortgage Loan may have been modified by a written instrument which has been
recorded, if necessary, to protect the interests of the Purchaser and which has
been delivered to the Trustee); satisfied, canceled or subordinated such
Mortgage in whole or in part; released the related Mortgaged Property in whole
or in part from the lien of such Mortgage; or executed any instrument of
release, cancellation, modification or satisfaction with respect thereto;

                           (xiii) A lender's policy of title insurance together
with a condominium endorsement, extended coverage endorsement, and an adjustable
rate mortgage endorsement (each as applicable) in an amount at least equal to
the Cut-off Date principal balance of each such Mortgage Loan or a commitment
(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,
the



<PAGE>


                                       -9-

transfer of the related Mortgage Loan to the Purchaser will not affect the
validity or enforceability of such policy and each such policy was issued by a
title insurer qualified to do business in the jurisdiction where the Mortgaged
Property is located and in a form acceptable to Fannie Mae or Freddie Mac, which
policy insures the Originator and successor owners of indebtedness secured by
the insured Mortgage, as to the first priority lien of the Mortgage; no claims
have been made under such lender's title insurance policy and no prior holder of
the related Mortgage, including the Originator, has done, by act or omission,
anything which would impair the coverage of such lender's title insurance
policy;

                           (xiv) Each Mortgage Loan was originated by the
Originator (or, if generated on behalf of the Originator by a person other than
the Originator, is subject to the same underwriting standards and procedures
used by the Originator in originating mortgage loans directly) or by a savings
and loan association, savings bank, commercial bank, credit union, insurance
company or similar institution which is supervised and examined by a federal or
state authority (including a mortgage broker), or by a mortgagee approved by the
Secretary of Housing and Urban Development pursuant to Sections 203 and 211 of
the National Housing Act;

                           (xv) With respect to each Adjustable-Rate Mortgage
Loan, on each adjustment date, the Mortgage Rate will be adjusted to equal the
Index plus the Gross Margin, rounded to the nearest 0.125%, subject to the
Periodic Rate Cap, the Maximum Mortgage Rate and the Minimum Mortgage Rate. The
related Mortgage Note is payable on the first day of each month in
self-amortizing monthly installments of principal and interest, with interest
payable in arrears, and requires a monthly payment which is sufficient to fully
amortize the outstanding principal balance of the Mortgage Loan over its
remaining term and to pay interest at the applicable Mortgage Rate. No Mortgage
Loan is subject to negative amortization;

                           (xvi) All of the improvements which were included for
the purpose of determining the appraised value of the Mortgaged Property lie
wholly within the boundaries and building restriction lines of such property,
and no improvements on adjoining properties encroach upon the Mortgaged
Property, except those, if any, which are insured against by the lender's title
insurance policy referred to in (xiii) above.

                           (xvii) All inspections, licenses and certificates
required to be made or issued with respect to all occupied portions of the
Mortgaged Property including but not limited to certificates of occupancy, have
been made or obtained from the appropriate authorities and the Mortgaged
Property is lawfully occupied under applicable law except as may otherwise be
insured against by the lender's title insurance policy referred to in (xiii)
above.

                           (xviii) All parties which have had any interest in
the Mortgage, whether as mortgagee, assignee, pledgee or otherwise, are (or,
during the period in which they held and disposed of such interest, were) in
compliance with any and all applicable licensing requirements of the laws of the
state wherein the Mortgaged Property is located;



<PAGE>


                                      -10-


                           (xix) The Mortgage Note and the related Mortgage are
genuine, and each is the legal, valid and binding obligation of the maker
thereof, enforceable in accordance with its terms and with applicable laws. All
parties to the Mortgage Note and the Mortgage had legal capacity to execute the
Mortgage Note and the Mortgage and each Mortgage Note and Mortgage have been
duly and properly executed by such parties;

                           (xx) The proceeds of each Mortgage Loan have been
fully disbursed, there is no requirement for future advances thereunder and any
and all requirements as to completion of any on-site or off-site improvements
and as to disbursements of any escrow funds therefor have been complied with,
except any Mortgaged Property or Mortgage Loan subject to an Escrow Withhold as
defined in the Originator's underwriting guidelines. All costs, fees and
expenses incurred in making, closing or recording the Mortgage Loans were paid;

                           (xxi) The related Mortgage contains customary and
enforceable provisions which render the rights and remedies of the holder
thereof adequate for the realization against the Mortgaged Property of the
benefits of the security, including, (i) in the case of a Mortgage designated as
a deed of trust, by trustee's sale, and (ii) otherwise by judicial foreclosure.
There is no homestead or other exemption available to the Mortgagor which would
materially interfere with the right to sell the Mortgaged Property at a
trustee's sale or the right to foreclose the Mortgage;

                           (xxii) With respect to each Mortgage constituting a
deed of trust, a trustee, duly qualified under applicable law to serve as such,
has been properly designated and currently so serves and is named in such
Mortgage, and 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;

                           (xxiii) There exist no deficiencies with respect to
escrow deposits and payments, if such are required, for which customary
arrangements for repayment thereof have not been made, and no escrow deposits or
payments of other charges or payments due the Originator have been capitalized
under the Mortgage or the related Mortgage Note;

                           (xxiv) The origination, collection and servicing
practices used by the Originator with respect to each Mortgage Loan have been in

other than real estate securing the Mortgagor's obligations;

                           (xxvi) No Mortgage Loan has a shared appreciation
feature, or other contingent interest feature;

                           (xxvii) The improvements upon each Mortgaged Property
are covered by a valid and existing hazard insurance policy with a generally
acceptable carrier that provides for fire extended coverage and such other
hazards as are customary in the area where the Mortgaged Property is located
representing coverage not less than the lesser of the outstanding principal
balance of the related Mortgage Loan or the minimum amount required to
compensate for damage or loss on a replacement cost basis. All individual
insurance policies and flood policies referred to in clause (xxviii) below
contain a standard mortgagee clause naming the Originator or the original
mortgagee, and its successors in interest, as mortgagee, and the Originator has
received no notice that any premiums due and payable thereon have not been paid;
the Mortgage obligates the Mortgagor thereunder to maintain all such insurance,
including flood insurance, at the Mortgagor's cost and expense, and upon the
Mortgagor's failure to do so, authorizes the holder of the Mortgage to obtain
and maintain such insurance at the Mortgagor's cost and expense and to seek
reimbursement therefor from the Mortgagor, except as may be limited or
restricted by applicable law;

                           (xxviii) If the Mortgaged Property is in an area
identified in the Federal Register by the Federal Emergency Management Agency as
having special flood hazards, a flood insurance policy in a form meeting the
requirements of the current guidelines of the Flood Insurance Administration is
in effect with respect to such Mortgaged Property with a generally acceptable
carrier in an amount representing coverage not less than the least of (A) the
original outstanding principal balance of the Mortgage Loan, (B) the minimum
amount required to compensate for damage or loss on a replacement cost basis or
(C) the maximum amount of insurance that is available under the Flood Disaster
Protection Act of 1973;

                           (xxix) There is no default, breach, violation or
event of acceleration existing under the Mortgage or the related Mortgage Note;
and the Originator has not waived any default, breach, violation or event of
acceleration;

                           (xxx) Each Mortgaged Property is improved by a one-
to four-family residential dwelling, including condominium units and dwelling
units in planned unit developments, which does not include (a) cooperatives or
(b) mobile homes and manufactured homes (as defined in the Fannie Mae
Seller-Servicer's Guide), except when the appraisal indicates that (i) the
mobile or manufactured home was built under the Federal Manufactured Home
Construction and Safety Standards of 1976 or (ii) otherwise assumes the
characteristics of site-built housing and meets local building codes, is readily
marketable, has been permanently affixed to the site, is not in a mobile home
"park," and is treated as real property under the applicable state law. With
respect to any Mortgage Loan that is secured by a leasehold estate, (a) the
lease is valid, in full force and effect; (b) all rents and other payments due
under the lease have been paid; (c) the lessee is not in default under any
provision of the lease; (d) the term of the lease exceeds the maturity date of
the related Mortgage Loan by at least five years and (e) the Mortgagee under the
Mortgage Loan is given notice and an opportunity to cure any defaults under the
lease;

                                      -12-

                           (xxxi) There is no obligation on the part of the
Originator or any other party under the terms of the Mortgage or related
Mortgage Note to make payments in lieu of or in addition to those made by the
Mortgagor;

                           (xxxii) Any future advances made prior to the related
Purchase Date have been consolidated with the outstanding principal amount
secured by the Mortgage, and the secured principal amount, as consolidated,
bears a single interest rate and single repayment term reflected on the Mortgage
Loan Schedule. The consolidated principal amount does not exceed the original
principal amount of the Mortgage Loan;

                           (xxxiii) Each Mortgage Loan was underwritten in
accordance with the Originator's underwriting guidelines;

                           (xxxiv) The Mortgage File contains an appraisal which
was performed by either (i) an appraiser who satisfied, and which was conducted
in accordance with, all of the applicable requirements of the Financial
Institutions Reform, Recovery and Enforcement Act of 1989, as amended or (ii) an
insured valuation model;

                           (xxxv) None of the Mortgage Loans is a graduated
payment mortgage loan, nor is any Mortgage Loan subject to a temporary buydown
or similar arrangement;

                           (xxxvi)   [Reserved].

                           (xxxvii) The Mortgage Loans comply in all material
respects with the description set forth under the heading "The Mortgage Pool" in
the Depositor's Prospectus Supplement, dated the date hereof (the "Prospectus

                           (xxxviii) The Mortgage contains an enforceable
provision for the acceleration of the payment of the unpaid principal balance of
the Mortgage Loan in the event that the Mortgaged Property is sold or
transferred without the prior written consent of the mortgagee thereunder,
except as may be limited by applicable law;

                           (xxxix) The information set forth in the Prepayment
Charge Schedule is complete, true and correct in all material respects at the
date or dates respecting which such information is furnished and each Prepayment
Charge is permissible and enforceable in accordance with its terms upon the full
and voluntary prepayment by the Mortgagor under applicable law (except to the
extent that: (1) the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium, receivership and other similar laws relating to
creditors' rights generally; or (2) the collectability thereof may be limited
due to acceleration in connection with a foreclosure or other involuntary
payoff;

                           (xl) Each Mortgage Loan is an obligation that is
principally secured by real property for purposes of the REMIC Provisions of the
Code;

                           (xli) No Mortgage Loan is a High Cost Loan as defined

                           (xlii) No proceeds from any Mortgage Loan were used
to finance single- premium credit insurance policies;

                           (xliii) No Mortgage Loan originated before October 1,
2002 will impose a Prepayment Charge for a term in excess of five years and no
Mortgage Loan originated on or after October 1, 2002 will impose a Prepayment
Charge for a term in excess of three years;

                           (xliv) No Mortgage Loan that is secured by property
located in the State of Georgia is either a "Covered Loan" or "High Cost Home
Loan" within the meaning of the Georgia Fair Lending Act, as amended (the
"Georgia Act");

                           (xlv) No Mortgagor has currently requested any relief
under the Soldiers' and Sailors' Civil Relief Act of 1940 or similar state laws;

                           (xlvi) The Master Servicer has fully furnished, in
accordance with the Fair Credit Reporting Act and its implementing regulations,
accurate and complete information (e.g., favorable and unfavorable) on its

                           (xlvii) No Mortgage Loan secured by a Mortgaged

                  (b) The Originator hereby represents and warrants, with
respect to the Initial Group II Mortgage Loans as of the Closing Date and with
respect to the subsequent Group II Mortgage Loans as of the respective
Subsequent Transfer Date or as of such date specifically provided herein:

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

                           (ii) No Mortgage Loan is subject to the requirements
of HOEPA and no Mortgage Loan is in violation of any state law or ordinance
similar to HOEPA;

                           (iii) No Mortgage Loan is secured by real property or
secured by a manufactured home located in the state of Georgia unless (x) such
Mortgage Loan was originated



<PAGE>


                                      -14-

prior to October 1, 2002 or (y) the property securing the Mortgage Loan is not,
nor will be, occupied by the Mortgagor as the Mortgagor's principal dwelling. No
Mortgage Loan is a "High Cost Home Loan" as defined in the Georgia Act. Each
Mortgage Loan that is a "Home Loan" under the Georgia Act complies with all
applicable provisions of the Georgia Act. No Mortgage Loan secured by owner
occupied real property or an owner occupied manufactured home located in the
State of Georgia was originated (or modified) on or after October 1, 2002
through and including March 6, 2003;

                  (iv) No borrower was encouraged or required to select a
Mortgage Loan product offered by the Mortgage Loan's originator which is a
higher cost product designed for less creditworthy borrowers, unless at the time
of the Mortgage Loan's origination, such borrower did not qualify taking into
account credit history and debt to income ratios for a lower cost credit product
then offered by the Mortgage Loan's originator or any affiliate of the Mortgage
Loan's originator;

                  (v) The methodology used in underwriting the extension of
credit for each Mortgage Loan employs objective mathematical principles which
relate the borrower's income, assets and liabilities to the proposed payment and
such underwriting methodology does not rely on the extent of the borrower'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 borrower had a reasonable ability to make
timely payments on the Mortgage Loan;

                  (vi) With respect to any Mortgage Loan that contains a
provision permitting imposition of a premium upon a prepayment prior to
maturity: (i) prior to the loan's origination, the borrower agreed to such
premium in exchange for a monetary benefit, including but not limited to a rate
or fee reduction, (ii) prior to the loan's origination, the borrower was offered
the option of obtaining a mortgage loan that did not require payment of such a
premium, (iii) the prepayment premium is disclosed to the borrower in the loan
documents pursuant to applicable state and federal law, and (iv) notwithstanding
any state or federal law to the contrary, the Servicer shall not impose such
prepayment premium in any instance when the mortgage debt is accelerated as the
result of the borrower's default in making the loan payments;

                  (vii) No borrower was required to purchase any credit life,
disability, accident or health insurance product as a condition of obtaining the
extension of credit. No borrower obtained a prepaid single premium credit life,
disability, accident or health insurance policy in connection with the
origination of the Mortgage Loan; No proceeds from any Mortgage Loan were used
to purchase single premium credit insurance policies as part of the origination
of, or as a condition to closing, such Mortgage Loan;

                  (viii) All points and fees related to each Mortgage Loan were
disclosed in writing to the borrower in accordance with applicable state and
federal law and regulation. Except in the case of a Mortgage Loan in an original
principal amount of less than $60,000 which would have resulted in an
unprofitable origination, no borrower was charged "points and fees" (whether or
not



<PAGE>


                                      -15-

financed) in an amount greater than 5% of the principal amount of such loan,
such 5% limitation is calculated in accordance with Fannie Mae's anti-predatory
lending requirements as set forth in the Fannie Mae Selling Guide;

                  (ix) 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 Mortgage Loan has been disclosed in
writing to the borrower in accordance with applicable state and federal law and
regulation; and

                  (x) The Servicer will transmit full-file credit reporting data
for each Mortgage Loan pursuant to Fannie Mae Guide Announcement 95-19 and that
for each Mortgage Loan, 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.


                   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 Originator, 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 Originator
(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 (xli), (xlii),
(xliii), (xlvi) and (xlvii) of Section 6(a) 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 breach shall give
prompt written notice to the other. 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
(xli), (xlii), (xliii), (xlvi) and (xlvii) of Section 6(a) 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 Originator promptly shall
deliver such missing document or cure such defect or breach in all material
respects, or in the event the Originator cannot

                                      -16-

deliver such missing document or such defect or breach cannot be cured, the
Originator shall, within 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(a)(xxxix)
resulting in the Master Servicer's inability to collect all or part of the
Prepayment Charge from the Mortgagor, in lieu of repurchase, the Originator
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.

                  The Originator 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 Originator 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 Originator, 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 breach shall give prompt
written notice within five Business Days to the others. Within ninety (90) days
of its discovery or its receipt of notice, the Originator 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
Originator 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 Originator 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 at 10:00 AM New York City time on

                           correct in all material respects as of the date as of
                           which 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

                           signatories other than the Purchaser as required
                           pursuant to the respective terms thereof;

                  (c)      The Originator 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
                           delivered by the Purchaser pursuant to Section 2.01
                           of the Pooling and Servicing Agreement; and

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

deliver or cause to be delivered to the Originator on the Closing Date, against
delivery and release by the Originator to the Trustee of all documents required

                  (c)      An Opinion of Counsel of the Originator, dated the

                  SECTION 11. [Reserved]

                  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 Originator's failure
to deliver the Mortgage Loans on or before the Closing Date. The Originator
hereby grants to the Purchaser a lien on and a continuing security interest in
the Originator's interest in each Mortgage Loan and each document and instrument
evidencing each such Mortgage Loan to secure the performance by the Originator
of its obligation hereunder, and the Originator 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 Originator agrees that,
upon acceptance of the Mortgage Loans by the Purchaser or its designee and
delivery of payment to the Originator, 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.




<PAGE>


                                      -20-

         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 Originator
in writing by the Purchaser; if to the Originator, addressed to the Originator
at 1100 Town & Country Road, Suite 1100, Orange, California 92868, Facsimile:
(714) 564-9639, Attention: General Counsel, or to such other address as the
Originator may designate in writing to the Purchaser.

                  SECTION 15. SEVERABILITY OF PROVISIONS. Any part, provision,
representation or warranty of this Agreement which is prohibited or which is
held to be void or unenforceable 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 unenforceable or is held to be void or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction as to any Mortgage Loan shall not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, the parties hereto waive any provision of law which prohibits
or renders void or unenforceable any provision hereof.

                  SECTION 16. AGREEMENT OF PARTIES. The Originator 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 purpose and to carry out the terms of this Agreement and the
Pooling and Servicing Agreement.

                  SECTION 17. SURVIVAL. The Originator agrees that the
representations, warranties and agreements made by it herein and in any
certificate or other instrument delivered pursuant hereto shall be deemed to be
relied upon by the Purchaser, notwithstanding any investigation heretofore or
hereafter made by the Purchaser or on its behalf, and that the representations,
warranties and agreements made by the Originator herein or in any such
certificate or other instrument shall survive the delivery of and payment for
the Mortgage Loans and shall continue in full force and effect, notwithstanding
any restrictive or qualified endorsement on the Mortgage Notes and
notwithstanding subsequent termination of this Agreement, the Pooling and
Servicing Agreement or the Trust Fund.

                  SECTION 18. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS,
DUTIES, OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES HERETO SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS (EXCLUDING THE CHOICE OF LAW
PROVISIONS) AND DECISIONS OF THE STATE OF NEW YORK. THE PARTIES HERETO INTEND
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
reference only and shall not limit or otherwise affect the meaning hereof. The
NIMS Insurer, if any, 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 Originator to the Purchaser as provided
in Section 4 hereof be, and be construed as, a sale of the Mortgage Loans by the
Originator to the Purchaser and not as a pledge of the Mortgage Loans by the
Originator to the Purchaser to secure a debt or other obligation of the
Originator. However, in the event that, notwithstanding the aforementioned
intent of the parties, the Mortgage Loans are held to be property of the
Originator, then, (a) it is the express intent of the parties that such
conveyance be deemed a pledge of the Mortgage Loans by the Originator to the
Purchaser to secure a debt or other obligation of the Originator 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
Originator to the Purchaser of a security interest in all of the Originator'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.

                                      -22-

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 Originator 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 Originator and the Purchaser have
caused their names to be signed by their respective officers thereunto duly
authorized as of the date first above written.

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


          [For Transferees Other Than Registered Investment Companies]

                  The undersigned hereby certifies as follows to [name of

Trustee, with respect to the mortgage pass-through certificates (the

meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third

such third party or taken other appropriate steps contemplated by Rule 144A to
conclude that such third party independently meets the definition of "qualified
institutional buyer" set forth in Rule 144A.

                  7. The Transferee will notify each of the parties to which
this certification is made of any changes in the information and conclusions
herein. Until such notice is given, the Transferee's purchase of the

                    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 2003-5,
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
____________________, 2003 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 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 Class R Certificates if, at any time during the taxable year
of the pass-through entity, a non-Permitted


                                      F-2-1

<PAGE>



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.

                  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.







                  IN WITNESS WHEREOF, the Owner has caused this instrument to be
executed on its behalf, pursuant to the authority of its Board of Directors, by
its [Vice] President, attested by its [Assistant] Secretary, this ____ day of
___________, 200__.

         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.
