February 1, 2003, among AMERIQUEST MORTGAGE SECURITIES INC., as Depositor,

                             PRELIMINARY STATEMENT:

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

          As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the Mortgage Loans and certain other related assets
(other than any Master Servicer Prepayment Charge Payment Amounts and the Net
WAC Rate Carryover Reserve Account) 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.

issued pursuant to one or more Indentures remain outstanding or the NIMS Insurer
is owed amounts in respect of its guarantee of payment on such notes; provided,
however, the NIMS Insurer shall not have any rights hereunder (except pursuant
to Section 11.01 in the case of clause (ii) below) during the period of time, if
any, that (i) the NIMS Insurer has not undertaken to guarantee certain payments
of notes issued pursuant to the Indenture or (ii) any default has occurred and
is continuing under the insurance policy issued by the NIMS Insurer with respect
to such notes.

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

          SECTION 2.01. Conveyance of Mortgage Loans.

          The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey to the Trustee
without recourse for the benefit of the Certificateholders all the right, title
and interest of the Depositor, including any security interest therein for the
benefit of the Depositor, in and to the Mortgage Loans identified on the
Mortgage Loan Schedule, the rights of the Depositor under the Mortgage Loan
Purchase Agreement, all other assets included or to be included in REMIC I. Such
assignment includes all interest and principal received by the Depositor or the
Master Servicer on or with respect to the Mortgage Loans (other than payments of
principal and interest due on such Mortgage Loans on or before the Cut-off
Date). The Depositor herewith delivers to the Trustee an executed copy of the
Mortgage Loan Purchase Agreement and the Trustee, on behalf of the
Certificateholders, acknowledges receipt of the same.

          In connection with such transfer and assignment, the Depositor does
hereby deliver to, and deposit with, the Trustee the following documents or
instruments with respect to each Mortgage Loan so transferred and assigned the
following documents or instruments (a "Mortgage File"):

          (i) the original Mortgage Note, endorsed in blank, without recourse,
     or in the following form: "Pay to the order of Deutsche Bank National Trust
     Company, as Trustee under the applicable agreement, without recourse," with
     all prior and intervening endorsements showing a complete chain of
     endorsement from the originator to the Person so endorsing to the Trustee,
     or with respect to any lost Mortgage Note, an original Lost Note Affidavit;
     provided however, that such substitutions of Lost Note Affidavits for
     original Mortgage Notes may occur only with respect to Mortgage Loans, the
     aggregate Cut-off Date Principal Balance of which is less than or equal to
     2.00% of the Pool Balance as of the Cut- off Date;

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

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

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

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

                                       49

<PAGE>

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

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

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

                                       50

<PAGE>

Rights, (ii) failure of the Master Servicer Termination Test, (iii) the
occurrence of a bankruptcy, insolvency or foreclosure relating to the
Originator, (iv) the occurrence of a servicing transfer as described in Section
7.02 hereof 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.
Notwithstanding the foregoing, if the Master Servicer is unable to pay the cost
of recording the Assignments of Mortgage, such expense will be paid by the
Trustee and shall be reimbursable to the Trustee as an Extraordinary Trust Fund
Expense.

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

          SECTION 2.02. Acceptance of REMIC I by the Trustee.

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

          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 and to certify in substantially the form attached
hereto as Exhibit C-1 (or cause the Custodian to certify in the form of the
Initial Certification attached to the Custodial Agreement) that, as to each
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan
paid in full or any Mortgage Loan specifically identified in the exception
report annexed thereto as not being covered by such certification), (i) all
documents constituting part of such Mortgage File (other than such documents
described in Section 2.01(v)) required to be delivered to it pursuant to this
Agreement are in its possession, (ii) such documents have been reviewed by it or
such Custodian and are not mutilated, torn or defaced unless initialed by the
related borrower and relate to such Mortgage Loan,

                                       51

<PAGE>

(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 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.

          (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

                                       52

<PAGE>

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 request the Trustee to (and the Trustee 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 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

                                       53

<PAGE>

     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
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

                                       54

<PAGE>

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 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 request the Trustee to (and the Trustee 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.

          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

                                       55

<PAGE>

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 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

                                       56

<PAGE>

     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

     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

          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

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

                         R-I Interest.

          The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Section 2.01 and Section 2.02, together with the assignment to it of all other

                                       58

hereby acknowledged. Concurrently with such assignment and delivery and in
exchange therefor, the Trustee, pursuant to the written request of the Depositor
executed by an officer of the Depositor, has executed, authenticated and
delivered to or upon the order of the Depositor, the Class R-I Interest in
authorized denominations. The interests evidenced by the Class R-I Interest,
together with the REMIC I Regular Interests, constitute the entire beneficial
ownership interest in REMIC I. The rights of the Class R Certificateholders and
REMIC II (as holder of the REMIC I Regular Interests) to receive distributions
from the proceeds of REMIC I in respect of the Class R-I Interest and the REMIC
I Regular Interests, respectively, and all ownership interests evidenced or

without recourse all the right, title and interest of the Depositor in and to
the REMIC I Regular Interests for the benefit of the Class R Certificateholders
(as holder of the Class R-I Interest and the Class R-II Interest) and REMIC II
(as holder of the REMIC I Regular Interests). The Trustee acknowledges receipt
of the REMIC I Regular Interests and declares that it holds and will hold the
same in trust for the exclusive use and benefit of all present and future Class
R Certificateholders (as holder of the Class R-I Interest and the Class R-II
Interest) and REMIC II (as holder of the REMIC I Regular Interests). The rights
of the Class R Certificateholders and REMIC II (as holder of the REMIC I Regular
Interest) to receive distributions from the proceeds of REMIC II in respect of
the Class R-II Interest and REMIC II Regular Interests, respectively, and all
ownership interests evidenced or constituted by the Class R-II Interest and the
REMIC II Regular Interests, shall be as set forth in this Agreement.

          SECTION 2.08. Issuance of Class R Certificates.

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

                          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

                                       60

<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

                                       61

<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
the Stated Principal Balance in final satisfaction of such Mortgage Loan, or
consent to the postponement of strict compliance with any such term or otherwise
grant indulgence to any Mortgagor (any and all such waivers, modifications,
variances, forgiveness of principal or interest, postponements, or indulgences
collectively referred to herein as

                                       62

<PAGE>

"forbearance"), PROVIDED, HOWEVER, that in determining which course of action
permitted by this sentence it shall pursue, the Master Servicer shall adhere to
the Loss Mitigation Action Plan. The Master Servicer's analysis supporting any
forbearance and the conclusion that any forbearance meets the standards of
Section 3.01 and the Loss Mitigation Action Plan shall be reflected in writing
in the Mortgage File.

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

          SECTION 3.03. [Reserved].

this Section 3.04, held in trust for the benefit of the Trustee and the
Certificateholders.

          (b) DEPOSITS TO THE COLLECTION ACCOUNT. On behalf of the Trust Fund,

mortgage loan servicing activities on a daily basis, and in no event more than

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 other
ancillary fees (but not Prepayment Charges) need not be deposited by the Master
Servicer in the Collection Account and shall upon collection, belong to the
Master Servicer as additional compensation for its servicing activities. In the
event the Master Servicer shall deposit in the Collection Account any amount not
required to be deposited therein, it may at any time withdraw such amount from
the Collection Account, any provision herein to the contrary notwithstanding.

          (c) ESCROW ACCOUNT. The Master Servicer shall segregate and hold all
funds collected and received pursuant to each Mortgage Loan which constitute
Escrow Payments separate and apart from any of its own funds and general assets
and shall establish and maintain in the name of the Trustee one or more accounts
(such account or accounts, the "Escrow Account") held in trust for the benefit

          (g) MASTER SERVICER TRANSFER OF FUNDS TO THE DISTRIBUTION ACCOUNT. On
behalf of the Trust Fund, the Master Servicer shall deliver to the Trustee in

<PAGE>

          (iii) any amounts to be paid in connection with a purchase of Mortgage
     Loans and REO Properties pursuant to Section 3.16 and Section 9.01;

          (iv) any Compensating Interest as required pursuant to Section
     4.03(e);

          (v) any Stayed Funds, as soon as permitted by the federal bankruptcy
     court having jurisdiction in such matters;

          (vi) any amounts required to be paid by the Master Servicer pursuant
     to Section 3.06 in connection with any losses realized on Permitted
     Investments with respect to funds held in the Collection Account; and

          (v) any amounts required to be paid to the Trustee from the assets of
     the Trust Fund on deposit in the Collection Account pursuant to this
     Agreement, including but not limited to amounts required to be paid to the
     Trustee pursuant to Section 7.02 and Section 8.05.

          Funds held in the Collection Account pursuant to Section 3.04(b) may
at any time be delivered by the Master Servicer to the Trustee for deposit into
the Distribution Account and for all purposes of this Agreement shall be deemed
to be a part of the Collection Account until the Business Day prior to the
Distribution Date; provided, however, that the Trustee shall have the sole
authority to withdraw any funds held pursuant to this paragraph. In the event
the Master Servicer shall deliver to the Trustee for deposit in the Distribution
Account any amount not required to be deposited therein, it may at any time
request that the Trustee withdraw such amount from the Distribution Account and
remit to it any such amount, any provision herein to the contrary
notwithstanding.

          (h) INVESTMENT OF ACCOUNT FUNDS. Funds on deposit in the Collection
Account, the Distribution Account, any REO Account and any Escrow Account may be
invested in Permitted Investments in accordance with the provisions set forth in
Section 3.06. Any investment earnings or interest paid on funds deposited in the
Collection Account, any REO Account and any Escrow Account (subject to Section
3.05(b)) shall accrue to the benefit of the Master Servicer and the Master
Servicer shall be entitled to retain and withdraw such interest from each such
account on a daily basis. Any investment earnings or interest paid on funds
deposited in the Distribution Account, shall accrue to the benefit of the
Trustee and the Trustee shall be entitled to retain and withdraw such interest
from each such account on a daily basis.

          Funds on deposit in the Net WAC Rate Reserve Carryover Account may be
invested in Permitted Investments in accordance with Section 3.06 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.

          (i) CREATION, LOCATION AND SUBSEQUENT TRANSFERS OF ACCOUNTS. Each
account created pursuant to this Agreement must be an Eligible Account. On or
prior to the Closing Date, the Master Servicer and the Trustee shall give
notice, to each other, the NIMS Insurer and the Depositor of the location of any
account created by it pursuant to this Agreement. From time to time, the Master
Servicer and the Trustee may each transfer any account created by it to a
different

                                       66

<PAGE>

depository institution provided that upon such transfer the written notice is
provided to all other parties listed in the preceding sentence.

          SECTION 3.05.  Permitted Withdrawals From the Collection Account,
                         Escrow Account and Distribution Account.

          (a) COLLECTION ACCOUNT. The Master Servicer may, from time to time,
withdraw from the Collection Account for the following purposes or as described
in Section 4.03:

          (i) to remit to the Trustee for deposit in the Distribution Account
     the amounts required to be so remitted pursuant to Section 3.04(g) or
     permitted to be so remitted pursuant to the last paragraph of Section
     3.04(g);

          (ii) subject to Section 3.12(c), to reimburse itself for (a) any
     unpaid Servicing Fees, (b) any unreimbursed Servicing Advances and (c) any
     unreimbursed Advances, the Master Servicer's right to reimburse itself
     pursuant to this subclause (ii) being limited to any Late Collections,
     Liquidation Proceeds, and Insurance Proceeds received on the related
     Mortgage Loan and any amounts received in respect of the rental of the
     related REO Property prior to an REO Disposition that represent payments of
     principal and/or interest respecting which any such advance was made;

          (iii) to reimburse itself for (a) any unpaid Servicing Fees to the
     extent not recoverable under Section 3.05(a)(ii) and (b) any unpaid
     Advances or Servicing Advances that have been deemed Nonrecoverable
     Advances or Nonrecoverable Servicing Advances;

          (iv) to pay to itself any Prepayment Interest Excess;

          (v) to reimburse itself for any amounts paid pursuant to Section
     3.12(b) (and not otherwise previously reimbursed);

          (vi) to pay to itself as servicing compensation any interest earned on
     funds in the Collection Account;

          (vii) subject to Section 4.03(b), to reimburse the Master Servicer in
     respect of any unreimbursed Advances to the extent of funds held in the
     Collection Account for future distribution that were not included in
     Available Funds for the preceding Distribution Date;

          (viii) to reimburse the Master Servicer or the Depositor for expenses
     incurred by or reimbursable to the Master Servicer or the Depositor, as the
     case may be, pursuant to Section 6.03;

          (ix) to remit to the Trustee any amounts that the Trustee is permitted
     to be paid or reimbursed from the assets of the Trust Fund pursuant to the
     terms of this Agreement, including the terms of Section 7.02(a) and Section
     8.05 of this Agreement;

                                       67

<PAGE>

          (x) to reimburse the NIMS Insurer, the Master Servicer (if the Master
     Servicer is not an Affiliate of the Originator) or the Trustee, as the case
     may be, for enforcement expenses reasonably incurred in respect of the
     breach or defect giving rise to the purchase obligation under Section 2.03
     of this Agreement that were included in the Purchase Price of the Mortgage
     Loan, including any expenses arising out of the enforcement of the purchase
     obligation;

          (xi) to pay to the Master Servicer, the Depositor or the Originator,
     as the case may be, with respect to each Mortgage Loan that has previously
     been purchased or replaced pursuant to Section 2.03 or 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 a
     particular depository to the Collection Account maintained at a different
     depository, pursuant to Section 3.04(i);

          (xii) [reserved];

          (xii) [reserved]; and

          (xiii) to clear and terminate the Collection Account upon the
     termination of this Agreement.

          On each Business Day as of the commencement of which the balance on
deposit in the Collection Account exceeds $75,000 following any withdrawals
pursuant to the next succeeding sentence, the amount of such excess shall be
remitted to the Trustee, but only if the Collection Account constitutes an
Eligible Account solely pursuant to clause (ii) of the definition of "Eligible
Account." If the balance on deposit in the Collection Account exceeds $75,000 as
of the commencement of business on any Business Day and the Collection Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of "Eligible Account," the Master Servicer shall, on or before 3:00 p.m. New
York time on such Business Day, withdraw from the Collection Account any and all
amounts payable or reimbursable to the Depositor, the Master Servicer, the
Trustee or any Sub-Servicer pursuant to Section 3.05 and shall pay such amounts
to the Persons entitled thereto.

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

          The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account, to the extent held by or on behalf of
it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (vii), (viii) and (xi)
above. The Master Servicer shall provide written notification to the Trustee and
the NIMS Insurer on or prior to the next succeeding Master Servicer Reporting
Date, upon making any withdrawals from the Collection Account pursuant to
subclause (viii) above.

                                       68

<PAGE>

          (b) ESCROW ACCOUNT. The Master Servicer may, from time to 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 Loan but only
     from amounts received on the related Mortgage Loan which represent late
     payments or Late Collections of Escrow Payments thereunder;

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

          (iv) for transfer to the Collection Account in accordance with the
     terms of this Agreement;

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

          (vi) to pay to the Master Servicer, or to the Mortgagor to the extent
     required by the related Mortgage Loan or Applicable Regulations, any
     interest paid on the funds deposited in the Escrow Account;

          (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 time, make
withdrawals from the Distribution Account, for any of the following purposes:

          (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;

                                       69

<PAGE>

          (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
     10.01(g)(iii); and

          (vi) to clear and terminate the Distribution Account pursuant 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

                                       70

<PAGE>

Account, and the REO Account from its own funds the amount of any loss incurred
in respect of any such Permitted Investment made with funds in such account
immediately upon realization of such loss.

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

          (d) Funds on deposit in the Net WAC Rate Carryover Reserve Account may
be invested in Permitted Investments in accordance with this Section 3.06 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 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

                                       71

<PAGE>

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 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

                                       72

<PAGE>

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 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

                                       73

<PAGE>

to enter into a substitution of liability agreement with such person, pursuant
to which the original Mortgagor is released from liability and such person is
substituted as the Mortgagor and becomes liable under the Mortgage Note,
provided that no such substitution shall be effective unless such person
satisfies the underwriting criteria of the Master Servicer. In connection with
any assumption or substitution, the Master Servicer shall apply such
underwriting standards and follow such practices and procedures as shall be
normal and usual in its general mortgage servicing activities and as it applies
to other mortgage loans owned solely by it. The Master Servicer shall not take
or enter into any assumption and modification agreement, however, unless (to the
extent practicable in the circumstances) it shall have received confirmation, in
writing, of the continued effectiveness of any applicable hazard insurance
policy, or a new policy meeting the requirements of this Section is obtained.
Any fee collected by the Master Servicer in respect of an assumption or
substitution of liability agreement will be retained by the Master Servicer as
additional servicing compensation. In connection with any such assumption, no
material term of the Mortgage Note (including but not limited to the related
Mortgage Rate and the amount of the Monthly Payment) may be amended or modified,
except as otherwise required pursuant to the terms thereof or otherwise
permitted under Section 3.01. The Master Servicer shall notify the Trustee and
any respective Custodian that any such substitution or assumption agreement has
been completed by forwarding to the Trustee or to such Custodian, as the case
may be, the executed original of such substitution or assumption agreement,
which document shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof.

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

          SECTION 3.12. Realization Upon Defaulted Mortgage Loans.

          (a) The Master Servicer shall, consistent with the Servicing Standard
and the Loss Mitigation Action Plan, foreclose upon or otherwise comparably
convert the ownership of properties securing such of the Mortgage Loans as come
into and continue in default and as to which no satisfactory arrangements can be
made for collection of delinquent payments pursuant to Section 3.02. The Master
Servicer shall be responsible for all costs and expenses incurred by it in any
such proceedings; provided, however, that such costs and expenses will be
recoverable as Servicing Advances by the Master Servicer as contemplated in
Section 3.05 and Section 3.13. The foregoing is subject to the provision that,
in any case in which Mortgaged Property shall have suffered damage from an
Uninsured Cause, the Master Servicer shall not be required to expend its own
funds toward the restoration of such property unless it shall determine in its
discretion that such restoration will increase the proceeds of liquidation of
the related Mortgage Loan after reimbursement to itself for such expenses.

                                       74

<PAGE>

          (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 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

                                       75

<PAGE>

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 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

                                       76

<PAGE>

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:

          (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;

                                       77

<PAGE>

          (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.

          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

                                       78

<PAGE>

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
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

                                       79

<PAGE>

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 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

                                       80

<PAGE>

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.

          (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.

                                       81

<PAGE>

          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

                                       82

<PAGE>

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, 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, 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.

          (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 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

                                       83

<PAGE>

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.

          (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

                                       84

<PAGE>

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.

<PAGE>

REMIC I Regular Interest I-LTP shall not be reduced until the Distribution Date

     (b) to the Holders of REMIC I Regular Interest I-LTA1, REMIC I Regular
Interest I- LTA2, REMIC I Regular Interest I-LTM1, REMIC I Regular Interest

are allocated to the Corresponding Certificates, until the Uncertificated
Balances of such REMIC I Regular Interests are reduced to zero;

     (c) to the Holders of REMIC I Regular Interest I-LTZZ, 1.00% of such
remainder (other than amounts payable under clause (d) below), until the
Uncertificated Balance of such REMIC I Regular Interest is reduced to zero; then

     (d) any remaining amount to the Holders of the Class R Certificates (in
respect of the Class R-I Interest); and

provided, however, that (i) 98.00% and (ii) 2.00% of any principal payments that
are attributable to an Overcollateralization Reduction Amount shall be allocated
to Holders of (i) REMIC I Regular Interest I-LTAA and REMIC I Regular Interest
I-LTP, in that order and (ii) REMIC I Regular Interest I-LTP, respectively;
provided that REMIC I Regular Interest I-LTP shall not be reduced until the
Distribution Date immediately following the expiration of the latest Prepayment
Charge as identified on the Prepayment Charge Schedule or any Distribution Date

The payment of the foregoing amounts to the Holders of REMIC I Regular Interest
I-LTP shall not reduce the Uncertificated Balance thereof.

     (iii) third, to the Holders of REMIC I Regular Interests, in an amount
equal to the remainder of the REMIC I Sub WAC Allocation Percentage of Available
Funds for such Distribution Date after the distributions made pursuant to clause
(i) above, allocated as follows:

Regular Interests first, so as to keep the Uncertificated Principal Balance of
each REMIC I Regular Interest ending with the designation "GRP" equal to 0.01%

Group; second, to each REMIC I Regular Interest ending with the designation
"SUB," so that the Uncertificated Principal Balance of each such REMIC I Regular
Interest is equal to 0.01% of the excess of (x) the aggregate Stated Principal
Balance of the Mortgage Loans in the related Group over (y) the Current
Principal Amount of the Class A Certificate in the related Group (except that if
any such excess is a larger number than in the preceding distribution period,
the least amount of principal shall be distributed to such REMIC I Regular
Interests such that

                                       86

the REMIC I Subordinated Balance Ratio is maintained); and third, any remaining

          On each Distribution Date, the Trustee shall withdraw any amounts then

Servicer pursuant to Section 2.03(b)(ii)(A) and Master Servicer Prepayment
Charge Payment Amounts payable by the Master servicer pursuant to Section
2.03(b)(ii)(B), subject to Section 2.03(b)(iii), in each case to the extent not
related to Principal Prepayments occurring after the related Prepayment Period,
and the Trustee shall distribute such amounts to the Holders of the Class P
Certificates. Such distributions shall not be applied to reduce the Certificate
Principal Balance of the Class P Certificates.

          (c) All distributions made with respect to each Class of Certificates
on each Distribution Date shall be allocated PRO RATA among the outstanding
Certificates in such Class based on their respective Percentage Interests.
Payments in respect of each Class of Certificates on each Distribution Date will
be made to the Holders of the respective Class of record on the related Record
Date (except as otherwise provided in Section 4.01(e) or Section 9.01 respecting
the final distribution on such Class), based on the aggregate Percentage
Interest represented by their respective Certificates, and shall be made by wire
transfer of immediately available funds to the account of any such Holder at a
bank or other entity having appropriate facilities therefor, if such Holder
shall have so notified the Trustee in writing at least five Business Days prior
to the Record Date immediately prior to such Distribution Date, or otherwise by
check mailed by first class mail

                                       91

<PAGE>

to the address of such Holder appearing in the Certificate Register. The final
distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the office of the Trustee
maintained for such purpose pursuant to Section 8.12 or such other location
specified in the notice to Certificateholders of such final distribution.

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

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

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

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

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

          Any funds not distributed to any Holder or Holders of Certificates of
such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
in trust by the Trustee and credited to the account of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(e) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non- tendering
Certificateholders to surrender their Certificates for cancellation in order to

make such distribution more convenient and/or more accessible to the above

containing the information set forth in subclauses (i) through (iii) above,

          Within a reasonable period of time after the end of each calendar

time during the calendar year was a Holder of a Residual Certificate a statement
setting forth the amount, if any, actually distributed with respect to the

Such obligation of the Trustee shall be deemed to have been satisfied to the
extent that substantially comparable information shall be prepared by the
Trustee and furnished to such Holders pursuant to the rules and regulations of
the Code as are in force from time to time.

          The Trustee shall, upon request, furnish to each Certificateholder and
the NIMS Insurer, during the term of this Agreement, such periodic, special, or

                          Shortfalls.

          (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
Master Servicer in respect of the related Distribution Date, the aggregate
amount of Advances outstanding after giving effect to such Advances, and the
aggregate amount of

                                       96

<PAGE>

Nonrecoverable Advances in respect of such Distribution Date and (ii) such other
information with respect to the Mortgage Loans as the Trustee may reasonably
require to perform the calculations necessary to make the distributions
contemplated by Section 4.01 and to prepare the statements to Certificateholders
contemplated by Section 4.02. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it 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 a
statement prepared by the Master Servicer setting forth the status of the
Collection Account as of the close of business on such Distribution Date and
showing, for the period covered by such statement, the aggregate amount of
deposits into and withdrawals from the Collection Account of each category of
deposit specified in Section 3.04(b) and each category of withdrawal specified
in Section 3.05. Such statement may be in the form of the then current Fannie
Mae Monthly Accounting Report for its Guaranteed Mortgage Pass-Through Program
with appropriate additions and changes, and shall also include information as to
the aggregate of the outstanding Stated Principal Balances of all of the
Mortgage Loans as of the last day of the calendar month immediately preceding
such Distribution Date. Copies of such statement shall be provided by the
Trustee to any Certificateholder and to any Person identified to the Trustee as
a prospective transferee of a Certificate, upon request at the expense of the
requesting party, provided such statement is delivered by the 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, which REO Property was acquired during or prior to the related
Prepayment Period 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

                                       97

<PAGE>

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.

          (e) The Master Servicer shall deliver to the Trustee for deposit into
the Distribution Account on or before 3:00 p.m. New York time on the Master
Servicer Remittance Date from its own funds an amount ("Compensating 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,

                                       98

<PAGE>

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 to
any REMIC II Regular Interest pursuant to Section 4.04(c), shall be allocated by
the Trustee on each Distribution Date as follows: first, to Net Monthly Excess
Cashflow; second, to the Class CE Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; third, to the Class M-4 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero;
fourth, to the Class MF-3 Certificates and the Class MV-3 Certificates, on a PRO
RATA basis, based on the respective Certificate Principal Balances of such
Classes of Certificates, until the respective Certificate Principal Balances
thereof have been reduced to zero; fifth, to the Class M-2 Certificates, until
the Certificate Principal Balance thereof has been reduced to zero; and sixth,
to the Class M-1 Certificates, until the Certificate Principal Balance thereof
has been reduced to zero. All Realized Losses to be allocated to the Certificate
Principal Balances of all Classes on any Distribution Date shall be so allocated
after the actual distributions to be made on such date as provided above. All
references above to the Certificate Principal Balance of any Class of
Certificates shall be to the Certificate Principal Balance of such Class
immediately prior to the relevant Distribution Date, before reduction thereof by
any Realized Losses, in each case to be allocated to such Class of Certificates,
on such Distribution Date.

          Any allocation of 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)(i) The REMIC I Marker Percentage of all Realized Losses on the
Mortgage Loans shall be allocated by the Trustee on each Distribution Date to
the following REMIC I Regular Interests in the specified percentages, as
follows: first, to Uncertificated Interest payable to the REMIC I Regular
Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate amount
equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively;
second, to the Uncertificated Balances of the REMIC I Regular Interest I-LTAA
and REMIC I Regular Interest I-

                                       99

<PAGE>

LTZZ up to an aggregate amount equal to the REMIC I Principal Loss Allocation
Amount, 98% and 2%, respectively; third, to the Uncertificated Balances of REMIC
I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM4 and REMIC I Regular
Interest I-LTZZ, 98%, 1.00% and 1%, respectively, until the Uncertificated
Balances of REMIC I Regular Interest I-LTM4 has been reduced to zero; fourth to
the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTMV3, REMIC I Regular Interest I-LTMF3 and REMIC I Regular Interest
I-LTZZ, 98%, 0.50%, 0.50% and 1%, respectively, until the Uncertificated
Balances of REMIC I Regular Interest I-LTMV3 and REMIC I Regular Interest
I-LTMF3 have been reduced to zero; fifth to the Uncertificated Balances of REMIC
I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM2 and REMIC I Regular
Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance
of REMIC I Regular Interest I-LTM2 has been reduced to zero; and sixth to the
Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM1 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM1 has been reduced to zero.

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

          SECTION 4.05. Compliance with Withholding Requirements.

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

          SECTION 4.06. Commission Reporting.

          (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

                                       100

<PAGE>

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.

          (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

                                       101

<PAGE>

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. [Reserved].

          SECTION 4.08. [Reserved].

          SECTION 4.09. [Reserved].

          SECTION 4.10 Net WAC Rate Carryover Reserve Account.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain with itself, as agent for the Trustee, a separate, segregated trust
account titled, "Net WAC Rate Carryover Reserve Account, Deutsche Bank National
Trust Company, as Trustee, in trust for the registered holders of Ameriquest
Mortgage Securities Inc., Asset-Backed Pass-Through Certificates, Series
2003-1." 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 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 and the Mezzanine Certificates, and will distribute such amounts
to the Holders of the Class A Certificates and the Mezzanine Certificates in the
amounts and priorities set forth in Section 4.01(a). 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

                                       101

<PAGE>

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

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

          (e) At the written direction of the Holders of a majority in
Percentage Interest in the Class CE Certificates, the Trustee shall direct any
depository institution maintaining the Net WAC Rate Carryover Reserve Account to
invest the funds in such account in one or more Permitted Investments bearing
interest or sold at a discount, and maturing, unless payable on demand, (i) no
later than the Business Day immediately preceding the date on which such funds
are required to be withdrawn from such account pursuant to this Agreement, if a
Person other than the Trustee or an Affiliate manages or advises such
investment, and (ii) no later than the date on which such funds are required to
be withdrawn from such account pursuant to this Agreement, if the Trustee or an
Affiliate manages or advises such investment. If no investment direction of the
Holders of a majority in Percentage Interest in the Class CE Certificates with
respect to the Net WAC Rate Carryover Reserve Account is received by the
Trustee, the Trustee shall invest the funds in the Deutsche Bank Institutional
Cash Management Fund 16-79 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 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.

<PAGE>

          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 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

                                       104

<PAGE>

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.

                                       106

<PAGE>

          (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 Depositor, the Trustee and the
Master Servicer are provided with an Opinion of Counsel which establishes to the
satisfaction of the Depositor, the Trustee and the Master Servicer that the
purchase of such Certificates is permissible under applicable law, will not
constitute or result in any 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 Person and
to negotiate the terms of any mandatory sale under clause (iii)(B) below and to
execute

                                       107

<PAGE>

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

                                       108

<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:

                                       109

<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 three separate Certificates, each
representing such Holder's respective Percentage Interest in the Class R-I
Interest and the Class R-II Interest, respectively, in each case that was
evidenced by the Class R Certificate being exchanged.

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

                                       110

<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 or any Person identified to the Trustee as a prospective
transferee of a Certificate, originals or copies

                                       111

<PAGE>

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 statements required to be delivered
to Certificateholders of the relevant Class pursuant to Section 4.02 since the
Closing Date, and all other notices, reports, statements and written
communications delivered to the Certificateholders of the relevant Class
pursuant to this Agreement since the Closing Date, (C) all certifications
delivered by a Responsible Officer of the Trustee since the Closing Date
pursuant to Section 10.01(h), (D) any and all Officers' Certificates delivered
to the Trustee by the Master Servicer since the Closing Date to evidence the
Master Servicer's determination that any Advance or Servicing Advance was, or if
made, would be a Nonrecoverable Advance or Nonrecoverable Servicing Advance,
respectively, and (E) any and all Officers' Certificates delivered to the
Trustee by the Master Servicer since the Closing Date pursuant to Section
4.04(a). Copies and mailing of any and all of the foregoing items will be
available from the Trustee upon request at the expense of the person requesting
the same.

                                   ARTICLE VI

                      THE DEPOSITOR AND THE MASTER SERVICER

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

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

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

          Subject to the following paragraph, the Depositor will keep in full
effect its existence, rights and franchises as a corporation under the laws of
the jurisdiction of its incorporation. Subject to the following paragraph, the
Master Servicer will keep in full effect its existence, rights and franchises as
a corporation under the laws of the jurisdiction of its incorporation and its
qualification as an approved conventional seller/servicer for Fannie Mae or
Freddie Mac in good standing. The Depositor and the Master Servicer each will
obtain and preserve its qualification to do business as a foreign corporation in
each jurisdiction in which such qualification is or shall be necessary to
protect the validity and enforceability of this Agreement, the Certificates or
any of the Mortgage Loans and to perform its respective duties under this
Agreement.

          The Depositor or the Master Servicer may be merged or consolidated
with or into any Person, or transfer all or substantially all of its assets to
any Person, in which case any Person resulting from any merger or consolidation
to which the Depositor or the Master Servicer shall be a party, or any Person
succeeding to the business of the Depositor or the Master Servicer, shall be the
successor of the Depositor or the Master Servicer, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Master Servicer shall be qualified to service mortgage loans on behalf of
Fannie Mae or Freddie Mac; and provided further that the Rating Agencies'
ratings of the Class A Certificates 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

                                       113

<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 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, liabilities (other than

                                       114

<PAGE>

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.

                                       115

<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.

                                       116

<PAGE>

          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.

                                       117

<PAGE>

          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

                                       118

<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

                                       120

<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

                                       121

<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

                                       122

<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

                                       123

<PAGE>

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

                                       124

<PAGE>

     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.

          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,

                                       125

<PAGE>

     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 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 any funds held by 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.

                                       126

<PAGE>

          SECTION 8.05. Trustee's Fees and Expenses.

          (a) The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself the Trustee Fee and, to the extent that the
funds therein are at any time insufficient for such purpose, the Depositor shall
pay such fees. The Trustee, or any director, officer, employee or agent of the
Trustee shall be indemnified by REMIC I and held harmless against any loss,
liability or expense (not including expenses, disbursements and advances
incurred or made by the Trustee including the compensation and the expenses and
disbursements of its agents and counsel, in the ordinary course of the Trustee's
performance in accordance with the provisions of this Agreement) incurred by the
Trustee in connection with any claim or legal action or any pending or
threatened claim or legal action arising out of or in connection with the
acceptance or administration of its obligations and duties under this Agreement,
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

                                       127

<PAGE>

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
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,

                                       128

<PAGE>

as well as all moneys, held by it hereunder (other than any Mortgage Files at
the time held by a Custodian, which Custodian shall become the agent of any
successor trustee hereunder), and the Depositor and the predecessor trustee
shall execute and deliver such instruments and do such other things as may
reasonably be required for more fully and certainly vesting and confirming in
the successor trustee all such rights, powers, duties and obligations.

          No successor trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.06 and the appointment of such
successor trustee shall not result in a downgrading of any Class of Certificates
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.

                                       129

<PAGE>

          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

                                       130

<PAGE>

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
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,

                                       131

<PAGE>

     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

                                       132

<PAGE>

less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans as
of the Cut-off Date and (B) if the Terminator is the Master Servicer and is an
affiliate of the Originator, the Master Servicer shall have delivered to the
Trustee 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

                                       133

<PAGE>

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

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

          SECTION 9.02 Additional Termination Requirements.

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

          (i) The Trustee shall specify the first day in the 90-day liquidation
     period in a statement attached to each Trust REMIC's final Tax Return
     pursuant to Treasury regulation Section 1.860F-1 and shall satisfy all
     requirements of a qualified liquidation under Section 860F of the Code and
     any regulations thereunder, as evidenced by an Opinion of Counsel obtained
     at the expense of the Terminator;

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

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

          (b) At the expense of the applicable Terminator (or in the event of
termination under Section 9.01(a)(ii), at the expense of the Trustee), the
Trustee shall prepare or cause to be prepared the documentation required in
connection with the adoption of a plan of liquidation of each Trust REMIC
pursuant to this Section 9.02.

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

                                    ARTICLE X

                                REMIC PROVISIONS

          SECTION 10.01. REMIC Administration.

          (a) The Trustee shall elect to treat each Trust REMIC as a REMIC under
the Code and, if necessary, under applicable state law. Each such election will
be made by the Trustee on Form 1066 or other appropriate federal tax or
information return or any appropriate state return for the taxable year ending
on the last day of the calendar year in which the Certificates are issued. For
the purposes of the REMIC election in respect of REMIC I, the REMIC I Regular
Interests shall be designated as the Regular Interests in REMIC I and the Class
R-I Interest shall be designated as the Residual Interest in REMIC I. The Class
A Certificates, the Mezzanine Certificates, the Class CE Certificates and the
Class P Certificates shall be designated as the Regular Interests in REMIC II
and the Class R-II Interest shall be designated as the Residual Interest in
REMIC II. The Trustee shall permit the creation of any "interests" in any Trust
REMIC (within the meaning of Section 860G of the Code) other than the REMIC I
Regular Interests and the interests represented by the Certificates.

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

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

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

          (e) The Trustee shall perform on behalf of each Trust REMIC all
reporting and other tax compliance duties that are the responsibility of such
REMIC under the Code, the REMIC Provisions or other compliance guidance issued
by the Internal Revenue Service or any state or local

                                       135

<PAGE>

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
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

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

<PAGE>

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.

                                       139

<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.

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

written request upon the Trustee to institute such action, suit or proceeding in
the name of the Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee, for 15 days
after its receipt of such notice, request and offer of indemnity, shall have
neglected or refused to institute any such action, suit or proceeding. It is
understood and intended, and expressly covenanted by each Certificateholder with
every other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatsoever by virtue of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, or to enforce any right
under this Agreement, except in the manner herein provided and for the equal,
ratable and common benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section, each and every Certificateholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

          SECTION 11.09. Grant of Security Interest.

          It is the express intent of the parties hereto that the conveyance of
the Mortgage Loans by the Depositor to the Trustee be, and be construed as, a
sale of the Mortgage Loans by the Depositor and not a pledge of the Mortgage
Loans by the Depositor to secure a debt or other obligation of the Depositor or
the 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

                                       143

<PAGE>

security interest under applicable law. Accordingly, the Depositor hereby grants
to the Trustee a security interest in the Mortgage Loans and all other property
described in clause (2) of the preceding sentence, for the purpose of securing
to the Trustee 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.

          SECTION 11.11 NIMS Insurer's Rights.

          Notwithstanding anything to the contrary anywhere in this Agreement,
all rights of the NIMS Insurer hereunder (i) shall not be operable whenever an
Insurer Default or an Insurer Insolvency Event and a Backup Insurer Default (as
defined in the Indenture) shall have occurred and be continuing and (ii) except
in the case of any right to indemnification hereunder shall permanently cease to
be operable upon the later to occur of (A) the payment in full of the NIM Notes
as provided in the Indenture and (B) the payment in full to the NIMS Insurer of
any amounts owed to the NIMS Insurer as provided in the Indenture.

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

Depositor, the Master Servicer, the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the Master
Servicer, the Trustee with the consent of the Holders of Certificates entitled

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

coupons in Classes and denominations representing Percentage Interests specified

limitations therein set forth, Certificates are exchangeable for new

<PAGE>

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 sum 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.

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 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.

sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

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 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.

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 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.

sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

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 Mortgage Loans at the Cut-off Date.

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.

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 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 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

                                      A-9-4

<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, 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 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.

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

          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

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

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"),

                                     A-10-3

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
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

                                     A-10-4

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
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.

"Depositor," which term includes any successor entity under the Agreement), the
Master Servicer and the Trustee, a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
the capitalized terms used 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 made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
First Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Record Date, in an amount equal to the product
of the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of 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
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
least five Business Days prior to the Record Date immediately prior to such
Distribution Date or otherwise by check mailed by first class mail to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register. Notwithstanding the above, the final distribution on
this Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency appointed by the Trustee for that purpose as provided in
the Agreement.

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

                                     A-11-3

<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

                                     A-11-4

<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 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.

Ladies and Gentlemen:

          Pursuant to Section 2.01 of the Pooling and Servicing Agreement, dated
as of February 1, 2003, among Ameriquest Mortgage Securities Inc. as Depositor,
Ameriquest Mortgage Company, as master servicer and Deutsche Bank National Trust
Company as trustee, we hereby acknowledge 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.

          The Trustee 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.

Ladies and Gentlemen:

          In accordance with Section 2.02 of the above-captioned Pooling and

          The Trustee has made no independent examination of any documents
contained in each Mortgage File beyond the review specifically required in the
above-referenced Pooling and Servicing Agreement. The Trustee makes no

<PAGE>

                        MORTGAGE LOAN PURCHASE AGREEMENT

          This is a Mortgage Loan Purchase Agreement (the "Agreement"), dated
February 4, 2003, between Ameriquest Mortgage Company, a Delaware corporation
(the "Originator") and Ameriquest Mortgage Securities Inc., a Delaware
corporation (the "Purchaser").

                              PRELIMINARY STATEMENT

          The Originator intends to sell the Mortgage Loans (as hereinafter
defined) to the Purchaser on the terms and subject to the conditions set forth
in this Agreement. The Purchaser shall deposit the Mortgage Loans into a
mortgage pool constituting the Trust Fund. The Trust Fund will be evidenced by a
single series of asset-backed pass-through certificates designated as Series
2003-1 (the "Certificates"). The Certificates will consist ten classes of
certificates. The Class CE Certificates, the Class P Certificates and the Class
R Certificates (collectively, the "Non-Offered Certificates") will be delivered
to the Originator or its designee as partial consideration for the Mortgage
Loans as further described below.

          The Certificates will be issued pursuant to a Pooling and Servicing
Agreement relating to the Series 2003-1 Certificates, dated as of February 1,
2003 (the "Pooling and Servicing Agreement"), among the Purchaser as depositor
(in such capacity, the "Depositor"), the Originator as master servicer (in such
capacity the "Master Servicer") and Deutsche Bank National Trust Company as
Trustee (the "Trustee "). Pursuant to the Pooling and Servicing Agreement, the
Depositor will assign all of its right, title and interest in and to the
Mortgage Loans, together with its rights under this Agreement, to the Trustee
for the benefit of the Certificateholders. Capitalized terms used but not
defined herein shall have the meanings set forth in the Pooling and Servicing
Agreement.

          The parties hereto agree as follows:

          SECTION 1. AGREEMENT TO PURCHASE. The Originator hereby sells, and the
Purchaser hereby purchases, on or before February 6, 2003 (the "Closing Date"),
certain adjustable- rate and fixed-rate conventional, one- to four-family,
residential mortgage loans (the "Mortgage Loans"), having an aggregate principal
balance as of the close of business on February 1, 2003 (the "Cut-off Date") of
$1,698,971,328.89, after giving effect to all payments due on the Mortgage Loans
on or before the Cut-off Date (the "Closing Balance"), whether or not received
including the right to any Prepayment Charges collected after the Cut-off Date
from the Mortgagors in connection with any Principal Prepayments on the Mortgage
Loans. Any payments (including Prepayment Charges) collected on or before the
Cut-off Date, including all scheduled payments of principal and interest due on
or before the Cut-off Date and collected after the Cut-off Date, shall belong to
the Originator.

          SECTION 2. MORTGAGE LOAN SCHEDULE. The Purchaser and the Originator
have agreed upon which of the mortgage loans owned by the Originator are to be
purchased by the Purchaser pursuant to this Agreement, and the Originator shall
prepare or cause to be prepared on

<PAGE>

                                       -2-

or prior to the Closing Date a final schedule (the "Closing Schedule")
describing such Mortgage Loans and setting forth all of the Mortgage Loans to be
purchased under this Agreement, including the related Prepayment Charges. The
Closing Schedule shall conform to the requirements set forth in this Agreement
and to the definition of "Mortgage Loan Schedule" under the Pooling and
Servicing Agreement. The Closing Schedule shall be used as the Mortgage Loan
Schedule under the Pooling and Servicing Agreement.

          SECTION 3. CONSIDERATION. In consideration for the Mortgage Loans to
be purchased hereunder, the Purchaser shall, as described in Section 8, (i) pay
to or upon the order of the Originator in immediately available funds an amount
(the "Purchase Price") equal to the net sale proceeds of the Class A-I
Certificates, the Class A-II Certificates, the Class M-1 Certificates, the Class
M-2 Certificates, the Class MF-3 Certificates, the Class MV-3 Certificates and
the Class M-4 Certificates, and (ii) deliver to the Originator or its designee,
the Non-Offered Certificates.

          SECTION 4. TRANSFER OF THE MORTGAGE LOANS.

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

               (b) DELIVERY OF MORTGAGE LOAN DOCUMENTS. The Originator will, on
or prior to the Closing Date, deliver or cause to be delivered to the Purchaser
or any assignee, transferee or designee of the Purchaser each of the following
documents for each Mortgage Loan:

          (i) the original Mortgage Note, endorsed in blank without recourse or
     in the following form: "Pay to the order of Deutsche Bank National Trust
     Company, as Trustee under the applicable agreement, without recourse," with
     all prior and intervening endorsements showing a complete chain of
     endorsement from the originator to the Person so endorsing to the Trustee,
     or with respect to any lost Mortgage Note, an original Lost Note Affidavit;
     PROVIDED HOWEVER, that such substitutions of Lost Note Affidavits for
     original Mortgage Notes may occur only with respect to Mortgage Loans, the
     aggregate Cut-off Date Principal Balance of which is less than or equal to
     2.00% of the Pool Balance as of the Cut- off Date;

<PAGE>

                                       -3-

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

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

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

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

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

          If any 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

<PAGE>

                                       -4-

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, (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

<PAGE>

                                       -5-

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.

enforceable against the Originator in accordance with its terms, except to the
extent that (a) the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium, receivership and other similar laws relating to
creditors' rights generally and (b) the remedy of specific performance and
injunctive and other forms of equitable relief may be

subject to the equitable defenses and to the discretion of the court before
which any proceeding therefor may be brought;

          (iii) The execution and delivery of this Agreement by the Originator,
the servicing of the Mortgage Loans by the Originator under the Pooling and
Servicing Agreement, the consummation of any other of the transactions herein

financial condition, properties or assets of the Originator taken as a whole;

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

litigation is pending against the Originator that would materially and adversely
affect the execution, delivery or enforceability of this Agreement or the
ability of the Originator to service the Mortgage Loans or to perform any of its

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

          The Originator hereby represents and warrants to the Purchaser that as
of the Closing Date:

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

<PAGE>

                                       -7-

               (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 Mortgagor, any
appraiser, any builder or developer, or any other party involved in the
origination of the Mortgage Loan or in the application of any insurance in
relation to such Mortgage Loan;

               (iv) All payments due prior to the Cut-off Date have 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;

               (v) Each Mortgage is a valid and enforceable first lien on the
Mortgaged Property, including all improvements thereon, subject only to (a) the
lien of nondelinquent current real property taxes and assessments, (b)
covenants, conditions and restrictions, rights of way, easements and other
matters of public record as of the date of recording of such Mortgage, such
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
properties are commonly subject which do not materially interfere with the
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 full right and authority, subject to no
interest or participation of, or 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

<PAGE>

                                       -8-

prior to, or equal with, the lien of the related Mortgage, except those which
are insured against by the title insurance policy referred to in (xiii) below;

               (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 and disclosure laws, and consummation of the transactions
contemplated hereby 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 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;

<PAGE>

                                       -9-

               (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

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;

               (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

                                      -10-

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

               (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

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

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;

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

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

in all material respects at the date or dates respecting which such information

Mortgagor under applicable law (except to the extent that: (1) the

          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 materially 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 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 herein, a breach of any such representation or warranty
shall in and of itself be deemed to materially adversely affect the interest

the Originator promptly shall deliver such missing

<PAGE>

                                      -14-

document or cure such defect or breach in all material respects, or in the event
the Originator cannot 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(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 and full 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

               occurred which, with notice or the passage of time, would
               constitute a default under this Agreement;

          (b)  The Purchaser shall have received, or the attorneys of the
               Purchaser shall have received in escrow (to be released from
               escrow at the time of closing), all Closing Documents as
               specified in Section 9 of this Agreement, in such forms as are
               agreed upon and acceptable to the Purchaser, duly executed by all

          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.

                                      -18-

     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,

          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.

          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. Any assignment of the interest of the Purchaser pursuant to Section 4(d)
hereof shall also be deemed

<PAGE>

                                      -20-

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.

<PAGE>

          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.

the securities referred to in the preceding paragraph. Further, in determining
such aggregate amount, the Transferee may have included securities owned by
subsidiaries of the Transferee, but only if such subsidiaries are consolidated
with the Transferee in its financial statements prepared in accordance with
generally accepted accounting principles and if the investments of such
subsidiaries are managed under the Transferee's direction. However, such
securities were not included if the Transferee is a majority-owned, consolidated
subsidiary of another enterprise and the Transferee is not itself a reporting
company under the Securities Exchange Act of 1934.

          5. The Transferee acknowledges that it is familiar with Rule 144A and
understands that the Transferor and other parties related to the Certificates
are relying and will continue to rely on the statements made herein because one
or more sales to the Transferee may be in reliance on Rule 144A.

    _____    _____      Will the Transferee be purchasing the Certificates
    Yes      No         only for the Transferee's own account?

          6. If the answer to the foregoing question is "no", the Transferee
agrees that, in connection with any purchase of securities sold to the
Transferee for the account of a third party (including any separate account) in
reliance on Rule 144A, the Transferee will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third party unless the Transferee has
obtained a current representation letter from 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 Certificates will
constitute a reaffirmation of this certification as of the date of such
purchase. In addition, if the Transferee is a bank or savings and loan as
provided above, the Transferee agrees that it will furnish to such parties
updated annual financial statements promptly after they become available.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [For Transferees That Are Registered Investment Companies]

          The undersigned hereby certifies as follows to [name of Transferor]
(the "Transferor") and Deutsche Bank National Trust Company, as Trustee, with
respect to the mortgage pass-through certificates (the "Certificates") described
in the Transferee Certificate to which this certification relates and to which
this certification is an Annex:

          1. As indicated below, the undersigned is the President, Chief
Financial Officer or Senior Vice President of the entity purchasing the
Certificates (the "Transferee") or, if the Transferee is a "qualified
institutional buyer" as that term is defined in Rule 144A under the Securities
Act of 1933 ("Rule 144A") because the Transferee is part of a Family of
Investment Companies (as defined below), is such an officer of the investment
adviser (the "Adviser").

          2. In connection with purchases by the Transferee, the Transferee is a
"qualified institutional buyer" as defined in Rule 144A because (i) the
Transferee is an investment company registered under the Investment Company Act
of 1940, and (ii) as marked below, the Transferee alone, or the Transferee's
Family of Investment Companies, owned at least $100,000,000 in securities (other
than the excluded securities referred to below) as of the end of the
Transferee's most recent fiscal year. For purposes of determining the amount of
securities owned by the Transferee or the Transferee's Family of Investment
Companies, the cost of such securities was used.

   ____   The Transferee owned $___________________ in securities (other than
          the excluded securities referred to below) as of the end of the
          Transferee's most recent fiscal year (such amount being calculated in
          accordance with Rule 144A).

   ____   The Transferee is part of a Family of Investment Companies which owned
          in the aggregate $______________ in securities (other than the
          excluded securities referred to below) as of the end of the
          Transferee's most recent fiscal year (such amount being calculated in
          accordance with Rule 144A).

          3. The term "FAMILY OF INVESTMENT COMPANIES" as used herein means two
or more registered investment companies (or series thereof) that have the same
investment adviser or investment advisers that are affiliated (by virtue of
being majority owned subsidiaries of the same parent or because one investment
adviser is a majority owned subsidiary of the other).

          4. The term "SECURITIES" as used herein does not include (i)
securities of issuers that are affiliated with the Transferee or are part of the
Transferee's Family of Investment Companies, (ii) securities issued or
guaranteed by the U.S. or any instrumentality thereof, (iii) bank deposit notes
and certificates of deposit, (iv) loan participations, (v) repurchase
agreements, (vi) securities owned but subject to a repurchase agreement and
(vii) currency, interest rate and commodity swaps.

          5. The Transferee is familiar with Rule 144A and understands that the
parties to which this certification is being made are relying and will continue
to rely on the statements made herein because one or more sales to the
Transferee will be in reliance on Rule 144A. In addition, the Transferee will
only purchase for the Transferee's own account.

          6. The undersigned will notify the parties to which this certification
is made of any changes in the information and conclusions herein. Until such
notice, the Transferee's purchase of the Certificates will constitute a
reaffirmation of this certification by the undersigned as of the date of such
purchase.

                    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 2003-1, [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.

                                      F-2-1

<PAGE>

          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 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

                                      F-2-2

<PAGE>

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.

          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.

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

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

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

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

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

          6. Capitalized terms not otherwise defined herein shall have the

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.
