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

                             PRELIMINARY STATEMENT:

                  The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate shall evidence the entire beneficial ownership interest
in each REMIC (as defined herein) created hereunder. The Trust Fund shall
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 shall elect to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets (other than any Master Servicer Prepayment Charge Payment
Amounts, the Pre-Funding Accounts, the Interest Coverage Accounts, any
Subsequent Mortgage Loan Interest, the Net WAC Rate Carryover Reserve Account
and the Cap Contracts) subject to this Agreement as a REMIC for federal income
tax purposes, and such segregated pool of assets shall be designated as "REMIC
I." The Class R-I Interest shall 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 shall be certificated.

                                   DEFINITIONS

                  SECTION 1.01 Defined Terms.

                  Whenever used in this Agreement, including, without
limitation, in the Preliminary Statement hereto, the following words and
phrases, unless the context otherwise requires, shall have the meanings
specified in this Article. Unless otherwise specified, all calculations
described herein shall be made on the basis of a 360-day year consisting of
twelve 30-day months and all calculations on each Regular Interest shall be made
on the basis of a 360-day year and the actual number of days in the month.

                  "Accrued Certificate Interest": With respect to any Class of
Certificates (other than the Class P Certificates and the Residual Certificates)
and each Distribution Date, interest accrued during the related Interest Accrual
Period at the Pass-Through Rate for such Certificate for such Distribution Date
on the Certificate Principal Balance, in the case of the Adjustable-Rate
Certificates and the Fixed-Rate Certificates, or on the Notional Amount, in the
case of the Class CE Certificates, of such Certificate immediately prior to such
Distribution Date. The Class P Certificates are not entitled to distributions in
respect of interest and, accordingly, shall not accrue interest. All
distributions of interest on the Adjustable-Rate Certificates shall be
calculated on the basis of a 360-day year and the actual number of days in the
applicable Interest Accrual Period. All distributions of interest on the
Fixed-Rate Certificates and the Class CE Certificates shall be based on a
360-day year consisting of twelve 30-day months. Accrued Certificate Interest
with respect to each Distribution Date, as to any Class A Certificate or
Mezzanine Certificate, shall be reduced by an amount equal to the portion
allocable to such Certificate pursuant to Section 1.02 hereof of the sum of (a)
the aggregate Prepayment Interest Shortfall, if any, for such Distribution Date
to the extent not covered by payments pursuant to Section 4.03(e) or allocated
to the Class CE Certificates pursuant to Section 1.02 and (b) the aggregate
amount of any Relief Act Interest Shortfall, if any, for such Distribution Date
not allocated to the Class CE Certificates pursuant to Section 1.02. Accrued

covered by payments by the Master Servicer pursuant to Section 4.03(e)) and
Relief Act Interest Shortfalls incurred in respect of the Mortgage Loans for any
Distribution Date shall be allocated first, (a) with respect to the Group I
Mortgage Loans, to REMIC I Regular Interest I-LT1 and REMIC I Regular Interest
I-LT1PF, in each case to the extent of one month's interest at the then
applicable respective REMIC I Remittance Rate on the respective Uncertificated

to the first three Distribution Dates, such amounts relating to the Initial
Group I Mortgage Loans shall be allocated to REMIC I Regular Interest I-LT1 and
such amounts relating to the Subsequent Group I Mortgage Loans shall be
allocated to REMIC I Regular Interest I-LT1PF, and (b) with respect to the Group

         aggregate amount of any Prepayment Interest Shortfalls (to the extent
         not covered by payments by the Master Servicer pursuant to Section
         4.03(e)) and the REMIC II Marker Allocation Percentage of any Relief
         Act Interest Shortfalls incurred in respect of the Mortgage Loans for
         any Distribution Date shall be allocated among REMIC II Regular

         aggregate amount of any Prepayment Interest Shortfalls (to the extent
         not covered by payments by the Master Servicer pursuant to Section
         4.03(e)) and the REMIC II Sub WAC Allocation Percentage of any Relief
         Act Interest Shortfalls incurred in respect of the Mortgage Loans for
         any Distribution Date shall be allocated to Uncertificated Interest

SECTION 1.03      Rights of the NIMS Insurer.

                  Each of the rights of the NIMS Insurer set forth in this
Agreement shall exist so long as (i) the NIMS Insurer has undertaken to
guarantee certain payments of notes issued pursuant to an Indenture and (ii) any
series of notes 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



                                       65

insurance policy issued by the NIMS Insurer with respect to such notes.

                                   ARTICLE II

                          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 and the
Certificate Insurer 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 (including any payments made under the Cap
Contracts). 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, the Original Pre-Funded Amounts
and the required deposit to the Interest Coverage Accounts, and the Trustee, on
behalf of the Certificateholders and the Certificate Insurer, 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 Initial Mortgage Loan so transferred and
assigned, and the Depositor shall, in accordance with Section 2.09, deliver or
cause to be delivered to the Trustee, with respect to each Subsequent Mortgage
Loan, 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 assigned in blank, without
         recourse;

                                       66
<PAGE>

                  (iv) the original recorded intervening Assignment or
         Assignments 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, 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 (or the related Subsequent
Transfer Date, with respect to the Subsequent Mortgage Loans) been submitted for
recording but either (x) has not been returned from the applicable public
recording office or (y) has been lost or such public recording office has
retained the original of such document, the obligations of the Depositor to
deliver such documents shall be deemed to be satisfied upon (1) delivery to the
Trustee, or to the appropriate Custodian on behalf of the Trustee, of a copy of
each such document certified by the applicable Originator in the case of (x)
above or the applicable public recording office in the case of (y) above to be a
true and complete copy of the original that was submitted for recording and (2)
if such copy is certified by the applicable Originator, delivery to the Trustee,
or to the appropriate Custodian on behalf of the Trustee, promptly upon receipt
thereof of either the original or a copy of such document certified by the
applicable public recording office to be a true and complete copy of the
original. If the original lender's title insurance policy was not delivered
pursuant to Section 2.01(vi) above, the Depositor shall deliver or cause to be
delivered to the Trustee, or to the appropriate Custodian on behalf of the
Trustee, promptly after receipt thereof, the original lender's title insurance
policy. The Depositor shall deliver or cause to be delivered to the Trustee, or
to the appropriate Custodian on behalf of the Trustee, promptly upon receipt
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 Seller) shall promptly
(and in no event later than thirty (30) Business Days, subject to extension upon
a mutual agreement between the Master Servicer and the Trustee, following the
later of (i) the Closing Date (or the related Subsequent Transfer Date, with
respect to the Subsequent Mortgage Loans), (ii) the date on which the Seller
receives the Assignment from the Custodian and (iii) the date of receipt by the
Master Servicer of the recording information for a Mortgage) submit or cause to
be submitted for recording, at no expense to the Trust Fund or the Trustee, in
the appropriate public office for real property records, each Assignment
referred to in Sections 2.01(iii) and (iv) above and shall execute each original
Assignment referred to in section 2.01(iii) above in the following form:
"Deutsche Bank National Trust Company, as Trustee under the applicable
agreement." In the



                                       67
<PAGE>

event that any such Assignment is lost or returned unrecorded because of a
defect therein, the Master Servicer (in its capacity as Seller) shall promptly
prepare or cause to be prepared a substitute Assignment or cure or cause to be
cured such defect, as the case may be, and thereafter cause each such Assignment
to be duly recorded.

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

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

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

SECTION 2.02      Acceptance of REMIC I by the Trustee.

                  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 shall hold such
documents and the other documents delivered to




                                       68
<PAGE>

it constituting a Mortgage File, and that it holds or shall hold all such assets
and such other assets included in the definition of "REMIC I" in trust for the
exclusive use and benefit of all present and future Certificateholders and the
Certificate Insurer.

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

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

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



                                       69
<PAGE>

defaced or does not conform to the requirements identified above, at the
conclusion of its review the Trustee (or a Custodian on behalf of the Trustee)
shall so notify the Depositor, the NIMS Insurer, the Certificate Insurer and the
Master Servicer. In addition, upon the discovery by the Depositor, the NIMS
Insurer, the Master Servicer, the Certificate Insurer or the Trustee of a breach
of any of the representations and warranties made by the Seller in the Mortgage
Loan Purchase Agreement in respect of any Mortgage Loan which materially
adversely affects such Mortgage Loan or the interests of the related
Certificateholders or the Certificate Insurer in such Mortgage Loan, the party
discovering such breach shall give prompt written notice to the other parties
and the Certificate Insurer.

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

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

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



                                       70
<PAGE>

as to which a document is missing, a material defect in a document exists or as
to which such a breach has occurred and is continuing shall constitute the sole
remedy respecting such omission, defect or breach available to the Trustee on
behalf of the Certificateholders.

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

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

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

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

                  (iii) If with respect to any Prepayment Period,

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

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

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



                                       71
<PAGE>

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

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

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



                                       72
<PAGE>

of this Agreement and, in the case of a substitution effected by the Seller, the
Mortgage Loan Purchase Agreement, including all applicable representations and
warranties thereof.

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

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

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

                  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

          thereof by the Depositor and the Trustee, constitutes a legal, valid
          and binding obligation of the Master Servicer, enforceable against the

          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

               (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 shall not (A) result in a breach of any term or provision of the
          charter or by-laws of the Master Servicer or (B) conflict with, result
          in a breach, violation or acceleration of, or result in a default
          under, the terms of any other material agreement or instrument to
          which the Master Servicer is a party or by which it may be bound, or
          any statute, order or regulation applicable to the Master Servicer of
          any court, regulatory body, administrative agency or governmental body
          having jurisdiction over the Master Servicer; and the Master Servicer

          violation of any statute, order or regulation of any court, regulatory
          body, administrative agency or governmental body having jurisdiction
          over it, which materially and adversely affects or, to the Master
          Servicer's knowledge, would in the future materially and adversely
          affect, (x) the ability




                                       74
<PAGE>

          of the Master Servicer to perform its obligations under this Agreement
          or (y) the business, operations, financial condition, properties or
          assets of the Master Servicer taken as a whole;

               (iv) The Master Servicer is an approved seller/servicer for
          Fannie Mae or Freddie Mac in good standing and is a HUD approved
          mortgagee pursuant to Section 203 and Section 211 of the National
          Housing Act;

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

               (vi) No consent, approval, authorization or order of any court or
          governmental agency or body is required for the execution, delivery
          and performance by the Master Servicer of, or compliance by the Master
          Servicer with, this Agreement or the consummation of the transactions
          contemplated by this Agreement, except for such consents, approvals,
          authorizations or orders, if any, that have been obtained prior to the
          Closing Date;

               (vii) The information set forth in the Prepayment Charge Schedule
          attached hereto as Schedule 2 (including the prepayment charge summary
          attached thereto) is complete, true and correct in all material
          respects at the date or dates respecting which such information is
          furnished and each Prepayment Charge is permissible and enforceable in
          accordance with its terms (except to the extent that (i) the
          enforceability thereof may be limited by bankruptcy, insolvency,
          moratorium, receivership and other similar laws relating to creditors'
          rights generally and (ii) the collectability thereof may be limited
          due to acceleration in connection with a foreclosure or other
          involuntary payment;

               (viii) The Master Servicer shall not waive any Prepayment Charge
          or part of a Prepayment Charge unless, (i) the enforceability thereof
          shall have been limited by bankruptcy, insolvency, moratorium,
          receivership and other similar laws relating to creditors' rights
          generally or (ii) the collectability thereof shall have been limited
          due to acceleration in connection with a foreclosure or other
          involuntary payment or (iii) in the Master Servicer's reasonable
          judgment as described in Section 3.01 hereof, (x) such waiver relates
          to a default or a reasonably foreseeable default, (y) such waiver
          would maximize recovery of total proceeds taking into account the
          value of such Prepayment Charge and related Mortgage Loan and (z)
          doing so is standard and customary in servicing similar Mortgage Loans
          (including any waiver of a Prepayment Charge in connection with a
          refinancing of a Mortgage Loan that is related to a default or a
          reasonably foreseeable default). In no event shall the Master Servicer
          waive a Prepayment Charge in connection with a refinancing of a
          Mortgage Loan that is not related to a default or a reasonably
          foreseeable default;

                                       75

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

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

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

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

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

below, in consideration of the Trustee's delivery on the Subsequent Transfer
Dates to or upon the order of the Depositor of all or a portion of the balance

The transfer and delivery to the Trustee for deposit in the Mortgage Pool by the

               be insolvent nor shall it have been rendered insolvent by such
               transfer nor shall it be aware of any pending insolvency;

                    (iv) such sale and transfer shall not result in a material
               adverse tax consequence to the Trust Fund or the
               Certificateholders;

                    (v) the Funding Period shall not have terminated;

                    (vi) the Depositor shall not have selected the Subsequent
               Mortgage Loans in a manner that it believed to be adverse to the
               interests of the Certificateholders;

                    (vii) the Depositor shall have delivered to the Trustee, the
               Certificate Insurer and the NIMS Insurer a Subsequent Transfer

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

SECTION 3.01      Master Servicer to Act as Master Servicer.

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

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

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

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

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

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



                                       82
<PAGE>

(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 and (v) to 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,



                                       83
<PAGE>

         (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 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, (ii) waive any provision of
any Mortgage Loan requiring the related Mortgagor to submit to mandatory
arbitration with respect to disputes arising thereunder or (iii) 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 (iii)
above shall not affect the amortization schedule of any Mortgage Loan for
purposes of any computation hereunder. The NIMS Insurer's prior written consent
shall be required for any modification, waiver or amendment if the aggregate
number of outstanding Mortgage Loans which have been modified, waived or amended
exceeds 5% of the number of Mortgage Loans as of the Cut-off Date. In the event
of any such arrangement pursuant to clause (iii) 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.



                                       84
<PAGE>

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

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

SECTION 3.03      [Reserved].

                  (a) Collection Account. On behalf of the Trust Fund, the
Master Servicer shall segregate and hold all funds collected and received

accordance with this Section 3.04, held in trust for the benefit of the Trustee,
the Certificate Insurer and the Certificateholders.

                  (b) Deposits to the Collection Account. On behalf of the Trust
Fund, the Master Servicer shall deposit or cause to be deposited in the clearing

deposits payments and collections on mortgage loans in connection with its
mortgage loan servicing activities on a daily basis, and in no event more than
one Business Day after the Master Servicer's receipt thereof, and shall
thereafter deposit in the Collection Account, in no event more than two Business
Days after the deposit of such funds into the clearing account, as and when
received or as otherwise required hereunder, and retain therein, the following

               Substitute Mortgage Loan shall be deemed to be the date of
               substitution);

               Servicer pursuant to Section 4.03(b); and

               2.03(b)(iii).

                  The foregoing requirements for deposit to the Collection

limiting the generality of the foregoing, payments in the nature of late payment

notwithstanding.

               funds held in the Collection Account for future distribution that

               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
               Seller, as the case may be, with respect to each Mortgage Loan

               Section 2.03 or Section 3.16(a) all amounts received thereon
               subsequent to the date of purchase or substitution, as the case

                                       90
<PAGE>

                    (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, the NIMS Insurer and the Certificate 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.

                  (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;

                                       91
<PAGE>

                    (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 and the
               Certificate Insurer in accordance with Section 4.01;

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

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

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

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



                                       92
<PAGE>

preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Trustee is the
obligor thereon, and (ii) no later than the date on which such funds are
required to be withdrawn from such Investment Account pursuant to this
Agreement, if the Trustee is the obligor thereon. All such Permitted Investments
shall be held to maturity, unless payable on demand. Any investment of funds in
an Investment Account shall be made in the name of the Trustee (in its capacity
as such) or in the name of a nominee of the Trustee. The Trustee shall be
entitled to sole possession (except with respect to investment direction of
funds held in the Collection Account, the Escrow Account, and the REO Account)
over each such investment and (except with respect to the income on funds held
in the Collection Account, the Escrow Account and the REO Account) the income
thereon, and any certificate or other instrument evidencing any such investment
shall be delivered directly to the Trustee or its agent, together with any
document of transfer necessary to transfer title to such investment to the
Trustee or its nominee. In the event amounts on deposit in an Investment Account
are at any time invested in a Permitted Investment payable on demand, the
Trustee shall:

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

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

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

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

                  (d) Funds on deposit in the Pre-Funding Accounts, the Interest
Coverage Accounts and the Net WAC Rate Carryover Reserve Account may be invested
in Permitted Investments in accordance with this Section 3.06 subject to any
limitations set forth in Section 4.07 (with respect to the Pre-Funding
Accounts), Section 4.08 (with respect to the Interest Coverage Accounts) 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



                                       93
<PAGE>

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, the Certificate 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 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



                                       94
<PAGE>

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 shall 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 shall cause to be maintained a flood insurance
policy in respect thereof. Such flood insurance shall be in an amount equal to
the lesser of (i) the unpaid Stated Principal Balance of the related Mortgage
Loan; (ii) the maximum amount of such insurance available for the related
Mortgaged Property under the national flood insurance program (assuming that the
area in which such Mortgaged Property is located is participating in such
program); and (iii) the maximum insurable value of the improvements which are
part of the related Mortgaged Property.

SECTION 3.09      Maintenance of Mortgage Blanket Insurance.

                  In the event that the Master Servicer shall obtain and
maintain a blanket policy with an insurer having a General Policy Rating of
"A:V" or better in Best's Key Rating Guide (or such other rating that is
comparable to such rating) insuring against hazard losses on all of the Mortgage
Loans, it shall conclusively be deemed to have satisfied its obligations as set
forth in the first two sentences of Section 3.08, it being understood and agreed
that such policy may contain a deductible clause, in which case the Master
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property or REO Property a policy complying with the first two
sentences of Section 3.08, and there shall have been one or more losses which
would have been covered by such policy, deposit to the Collection Account from
its own funds the amount not otherwise payable under the blanket policy because
of such deductible clause. In connection with its activities as administrator
and servicer of the Mortgage Loans, the



                                       95
<PAGE>

Master Servicer agrees to prepare and present, on behalf of itself, the Trustee,
the Certificate Insurer and the Certificateholders, claims under any such
blanket policy in a timely fashion in accordance with the terms of such policy.

SECTION 3.10      Fidelity Bond; Errors and Omissions Insurance.

                  The Master Servicer shall keep in force during the term of
this Agreement a policy or policies of insurance covering errors and omissions
for failure in the performance of the Master Servicer's obligations under this
Agreement, which policy or policies shall be in such form and amount that would
meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of
the Mortgage Loans, unless the Master Servicer has obtained a waiver of such
requirements from Fannie Mae or Freddie Mac. The Master Servicer shall also
maintain a fidelity bond in the form and amount that would meet the requirements
of Fannie Mae or Freddie Mac, unless the Master Servicer has obtained a waiver
of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall
provide the Trustee, the Certificate Insurer (upon reasonable request) 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 shall, to the extent it has knowledge of
any conveyance or prospective conveyance of any Mortgaged Property by any
Mortgagor (whether by absolute conveyance or by contract of sale, and whether or
not the Mortgagor remains or is to remain liable under the Mortgage Note and/or
the Mortgage), exercise its rights to accelerate the maturity of such Mortgage
Loan under the "due-on-sale" clause, if any, applicable thereto; provided,
however, that the Master Servicer shall not exercise any such rights if
prohibited by law from doing so. If the Master Servicer reasonably believes it
is unable under applicable law to enforce such "due-on-sale" clause, or if any
of the other conditions set forth in the proviso to the preceding sentence
apply, the Master Servicer is authorized to enter into an assumption and
modification agreement from or with the person to whom such property has been
conveyed or is proposed to be conveyed, pursuant to which such person becomes
liable under the Mortgage Note and, to the extent permitted by applicable state
law, the Mortgagor remains liable thereon. The Master Servicer is also
authorized to enter into a substitution of liability agreement with such person,
pursuant to which the original Mortgagor is released from liability and such
person is substituted as the Mortgagor and becomes liable under the Mortgage
Note, provided that no such substitution shall be effective unless such person
satisfies the underwriting criteria of the Master Servicer. In connection with
any assumption or substitution, the Master Servicer shall apply such
underwriting standards and follow such practices and procedures as shall be
normal



                                       96
<PAGE>

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 shall 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 shall 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 shall increase the
proceeds of liquidation of the related Mortgage Loan after reimbursement to
itself for such expenses.

                  (b) Notwithstanding the foregoing provisions of this Section
3.12 or any other provision of this Agreement, with respect to any Mortgage Loan
as to which the Master Servicer has received actual notice of, or has actual
knowledge of, the presence of any toxic or hazardous substance on the related
Mortgaged Property, the Master Servicer shall not, on behalf of the Trustee,
either (i) obtain title to such Mortgaged Property as a result of or in lieu of
foreclosure



                                       97
<PAGE>

or otherwise or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged Property, if, as a result of any such action,
the Trustee, the Trust Fund or the Certificateholders would be considered to
hold title to, to be a "mortgagee-in-possession" of, or to be an "owner" or
"operator" of such Mortgaged Property within the meaning of the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended from
time to time, or any comparable law, unless the Master Servicer has also
previously determined, based on its reasonable judgment and a report prepared by
a Person who regularly conducts environmental audits using customary industry
standards, that:

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

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

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

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

                  If the Master Servicer determines, as described above, that it
is in the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Master Servicer shall take such action as it deems to be in the best
economic interest of the Trust Fund; provided, however, that the Master Servicer
shall not proceed with foreclosure or acceptance of a deed in lieu of
foreclosure if the estimated costs of the environmental clean up, as estimated
in the environmental audit report, together with the Advances made by the Master
Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu
of foreclosure exceeds the estimated value of the Mortgaged Property. The cost
of any such compliance, containment, cleanup or remediation shall be advanced by
the Master



                                       98
<PAGE>

Servicer, subject to the Master Servicer's right to be reimbursed therefor from
the Collection Account as provided in Section 3.05(a)(v), such right of
reimbursement being prior to the rights of Certificateholders to receive any
amount in the Collection Account received in respect of the affected Mortgage
Loan or other Mortgage Loans.

                  (c) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds, Subsequent Recoveries or Liquidation Proceeds, in respect of
any Mortgage Loan, shall 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 shall be allocated by the Master Servicer as follows: FIRST, to
unpaid Servicing Fees; and SECOND, to the balance of the interest then due and
owing. The portion of the recovery so allocated to unpaid Servicing Fees shall
be reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section
3.05(a)(ii).

SECTION 3.13 Title, Management and Disposition of REO Property.

                  (a) The deed or certificate of sale of any REO Property shall
be taken in the name of the Trustee, or its nominee, in trust for the benefit of
the Certificateholders and the Certificate Insurer. Pursuant to the power of
attorney granted in Section 3.01, the Master Servicer is hereby authorized to
transfer the title of any REO Property taken in the name of the Trustee to a
third party purchaser pursuant to this Section 3.13 without further
documentation of its authority as attorney-in-fact for the Trustee on behalf of
the Trust. The Master Servicer, on behalf of the Trust Fund (and on behalf of
the Trustee for the benefit of the Certificateholders), shall either sell any
REO Property before the close of the third taxable year after the year the Trust
Fund acquires ownership of such REO Property for purposes of Section 860G(a)(8)
of the Code or request from the Internal Revenue Service, no later than 60 days
before the day on which the three-year grace period would otherwise expire, an
extension of the three-year grace period, unless the Master Servicer shall have
delivered to the Trustee, the NIMS Insurer, the Certificate Insurer and the
Depositor an Opinion of Counsel, addressed to the Trustee, the NIMS Insurer, the
Certificate Insurer and the Depositor, to the effect that the holding by the
Trust Fund of such REO Property subsequent to three years after its acquisition
shall 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.



                                       99
<PAGE>

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

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

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

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

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

                  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 shall 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:



                                      100
<PAGE>

                  (i) authorize the Trust Fund to enter into, renew or extend
         any New Lease with respect to any REO Property, if the New Lease by its
         terms shall 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 shall constitute Rents from Real
         Property;

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

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

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



                                      101
<PAGE>

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

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

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

                  (f) The proceeds from the REO Disposition, net of any amount
required by law to be remitted to the Mortgagor under the related Mortgage Loan
and net of any payment or reimbursement to the Master Servicer or any
Sub-Servicer as provided above, shall be deposited in the Distribution Account
in accordance with Section 3.04(g)(ii) on the Master Servicer Remittance Date in
the month following the receipt thereof for distribution on the related
Distribution Date in accordance with Section 4.01. Any REO Disposition shall be
for cash only (unless changes in the REMIC Provisions made subsequent to the
Startup Day allow a sale for other consideration).

SECTION 3.14      [Reserved].

SECTION 3.15      Reports of Foreclosure and Abandonment of Mortgaged
                  Properties.

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



                                      102
<PAGE>

reports shall be in form and substance sufficient to meet the reporting
requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

SECTION 3.16      Optional Purchase of Defaulted Mortgage Loans.

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

                    (ii) During the first full calendar 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 shall 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 calendar month following the calendar 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 shall
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
shall be so deposited) of a Servicing Officer and shall request delivery to it
of the Mortgage File. Upon receipt of such certification and request, the
Trustee or such Custodian, as the case may be, shall promptly release (and in no
event more than three (3) Business Days thereafter) the related Mortgage File to
the Master Servicer. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Collection
Account or the Distribution Account.

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

                  (c) Upon written certification of a Servicing Officer, the
Trustee shall execute and deliver to the Master Servicer any court pleadings,
requests for trustee's sale or other documents reasonably necessary to the
foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal
action brought to obtain judgment against any Mortgagor on the Mortgage Note or
Mortgage or to obtain a deficiency judgment, or to enforce any other remedies



                                      104
<PAGE>

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 shall not invalidate or otherwise affect the
lien of the Mortgage, except for the termination of such a lien upon completion
of the foreclosure or trustee's sale.

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

SECTION 3.18      Servicing Compensation.

                  As compensation for the activities of the Master Servicer
hereunder, the Master Servicer shall be entitled to the Servicing Fee with
respect to each Mortgage Loan payable solely from payments of interest in
respect of such Mortgage Loan, subject to Section 4.03(e). In addition, the
Master Servicer shall be entitled to recover unpaid Servicing Fees out of
Insurance Proceeds, Subsequent Recoveries 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 amounts, 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 shall deliver to the Trustee, the NIMS
Insurer, the Certificate Insurer, the Depositor and each Rating Agency on or
before March 15th of each calendar year commencing in 2005, an Officers'
Certificate in a form similar to Exhibit M attached hereto agreeable to the
parties hereto, stating, as to each signatory thereof, that (i) a review of the



                                      105
<PAGE>

activities of the Master Servicer during the preceding calendar year and of
performance under this Agreement has been made under such officers' supervision
and (ii) to the best of such officers' knowledge, based on such review, the
Master Servicer has fulfilled all of its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the
nature and status thereof. Copies of any such statement shall be provided by the
Trustee to the Certificate Insurer and any Certificateholder and to any Person
identified to the Trustee as a prospective transferee of a Certificate, upon the
request and at the expense of the requesting party, provided that such statement
is delivered by the Master Servicer to the Trustee.

SECTION 3.20      Independent Public Accountants' Servicing Report.

                  Not later than March 15th of each calendar year commencing in
2005, the Master Servicer, at its expense, shall cause a nationally recognized
firm of independent certified public accountants to furnish to the Master
Servicer a report stating that (i) it has obtained a letter of representation
regarding certain matters from the management of the Master Servicer which
includes an assertion that the Master Servicer has complied with certain minimum
residential mortgage loan servicing standards, identified in the Uniform Single
Attestation Program for Mortgage Bankers established by the Mortgage Bankers
Association of America, with respect to the servicing of residential mortgage
loans during the most recently completed calendar year and (ii) on the basis of
an examination conducted by such firm in accordance with standards established
by the American Institute of Certified Public Accountants, such representation
is fairly stated in all material respects, subject to such exceptions and other
qualifications that may be appropriate. In rendering its report such firm may
rely, as to matters relating to the direct servicing of residential mortgage
loans by Sub-Servicers, upon comparable reports of firms of independent
certified public accountants rendered on the basis of examinations conducted in
accordance with the same standards (rendered within one year of such report)
with respect to those Sub-Servicers. Immediately upon receipt of such report,
the Master Servicer shall furnish a copy of such report to the Trustee, the NIMS
Insurer, the Certificate Insurer and each Rating Agency. Copies of such
statement shall be provided by the Trustee to any Certificateholder upon request
at the Master Servicer's expense, provided that such statement is delivered by
the Master Servicer to the Trustee. In the event such firm of independent
certified public accountants requires the Trustee to agree to the procedures
performed by such firm, the Master Servicer shall direct the Trustee in writing
to so agree; it being understood and agreed that the Trustee shall deliver such
letter of agreement in conclusive reliance upon the direction of the Master
Servicer, and the Trustee has not made any independent inquiry or investigation
as to, and shall have no obligation or liability in respect of, the sufficiency,
validity or correctness of such procedures.

SECTION 3.21      Access to Certain Documentation.

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



                                      106
<PAGE>

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

SECTION 3.22      [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 (an "Advance Facility") with any Person which provides that such Person
(an "Advancing Person") may fund Advances and/or Servicing Advances to the Trust
Fund under this Agreement, although no such facility shall reduce or otherwise
affect the Master Servicer's obligation to fund such Advances and/or Servicing
Advances. If the Master Servicer enters into such an Advance Facility pursuant
to this Section 3.23, upon reasonable request of the Advancing Person, the
Trustee shall execute a letter of acknowledgment, confirming its receipt of
notice of the existence of such Advance Facility. To the extent that an
Advancing Person funds any Advance or any Servicing Advance and provides the
Trustee with notice acknowledged by the Master Servicer that such Advancing
Person is entitled to reimbursement directly from the Trustee pursuant to the
terms of the Advance Facility, such Advancing Person shall be entitled to
receive reimbursement pursuant to this Agreement for such amount to the extent
provided in Section 3.23(b). Such notice from the Advancing Person must specify
the amount of the reimbursement, the Section of this Agreement that permits the
applicable Advance or Servicing Advance to be reimbursed and the section(s) of
the Advance Facility that entitle the Advancing Person to request reimbursement
from the Trustee, rather than the Master Servicer, and include the Master
Servicer's acknowledgment thereto or proof of an Event of Default under the
Advance Facility. The Trustee shall have no duty or liability with respect to
any calculation of any reimbursement to be paid to an Advancing Person and shall
be entitled to rely without independent investigation on the Advancing Person's
notice provided pursuant to this Section 3.23. An Advancing Person whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the qualifications of a Master Servicer
or a Sub-Servicer pursuant to Section 6.06 hereof and shall 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) or Section 3.05(a)(v) prior to the remittance
to the Trust Fund, but instead the Master Servicer shall include such amounts in
the



                                      107
<PAGE>

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) or Section 3.05(a)(v), 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 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 shall not result in the
reduction or withdrawal of the then-current ratings of any outstanding Class of
Certificates (and with respect to the Insured Certificates, without regard to
the Policy) or any other notes secured by collateral which includes all or a
portion of the Class CE Certificates, the Class P Certificates and/or the
Residual Certificates, notwithstanding anything to the contrary in this
Agreement.

               Percentage of Available Funds for such Distribution Date after
               the distributions made pursuant to clause (i) above, such that
               distributions of principal shall be deemed to be made to the

               designation "SUB," so that the Uncertificated Balance of each
               such REMIC II Regular Interest is equal to 0.01% of the excess of
               (x) the aggregate Stated Principal Balance of the Mortgage Loans
               in the related Loan Group over (y) the current Certificate
               Principal Balance of the Class A Certificate in the related Loan
               Group (except that if any such excess is a larger number than in
               the preceding distribution period, the least amount of principal
               shall be distributed to such REMIC II Regular Interests such that
               the REMIC II Subordinated Balance Ratio is maintained); and
               third, any remaining principal to REMIC II Regular Interest
               II-LTXX.

         Certificates, to the extent remaining undistributed after the
         distribution of the Group I Interest Remittance Amount, as set forth in
         Section 4.01(a)(2)(I)(ii) above;

                  (ii) sequentially, to the Holders of the Class M-1, Class M-2,

         any remaining amounts in reduction of the Certificate Principal Balance

         thereof has been reduced to zero; and

                  (vi) to the Holders of the Class R Certificates, any remaining

in that order, until their respective Certificate Principal Balances have been
reduced to zero; provided, however, on any Distribution Date on which the
aggregate Certificate Principal Balance of the Class CE Certificates and the
Mezzanine Certificates have been reduced to zero, notwithstanding anything
contained herein to the contrary, all distributions of principal to the Group II
Certificates shall be distributed concurrently, on a PRO RATA basis based on the
Certificate Principal Balance of each such Class.

                  On each Distribution Date, following the foregoing
distributions, an amount equal to the amount of Subsequent Recoveries deposited
into the Collection Account pursuant to Section 3.05 and included in the
Available Funds for such Distribution Date shall be applied to increase the
Certificate Principal Balance of the Class of Certificates with the Highest
Priority up to the extent of such Realized Losses previously allocated to that
Class of Certificates pursuant to Section 4.04. An amount equal to the amount of
any remaining Subsequent Recoveries shall be applied to increase the Certificate
Principal Balance of the Class of Certificates with the next Highest Priority,
up to the amount of such Realized Losses previously allocated to that Class of
Certificates pursuant to Section 4.04, and so on. Holders of such Certificates
shall not be entitled to any distribution in respect of interest on the amount
of such increases for any Interest Accrual Period preceding the Distribution
Date on which such increase occurs. Any such increases shall be applied to the
Certificate Principal Balance of each Certificate of such Class in accordance
with its respective Percentage Interest.

                  On each Distribution Date, after making the distributions of
the Available Funds as set forth above, the Trustee shall FIRST, withdraw from
the Net WAC Rate Carryover Reserve Account all income from the investment of
funds in the Net WAC Rate Carryover Reserve Account and distribute such amount

WAC Rate Carryover Reserve Account, to the extent of amounts remaining on
deposit therein, the amount of any Net WAC Rate Carryover Amount for such
Distribution Date and distribute such amount as follows:

the related Cap Amount, in each case up to a maximum amount equal to the related
Net WAC Rate Carryover Amount for such Distribution Date;

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

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

                  FOURTH, sequentially to the Class M-1, Class M-2, Class M-3,
Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class M-10

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

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

                  (c) All distributions made with respect to each Class of
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 shall 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 to the
address of such Holder appearing in the Certificate Register. The final
distribution on each Certificate shall be made in like manner, but only upon
presentment and surrender of such Certificate at the office of the Trustee
maintained for such purpose pursuant to Section 8.12 or such other location
specified in the notice to Certificateholders of such final distribution.
Payments to the Certificate Insurer on any Distribution Date shall be made by
wire transfer of immediately available funds to the account designated by the
Certificate Insurer under the Premium Letter (as defined in the Insurance
Agreement).

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

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

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

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

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

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

                  (f) Notwithstanding anything to the contrary herein, (i) in no
event shall the Certificate Principal Balance of a Class A Certificate or a
Mezzanine Certificate be reduced more than once in respect of



                                      119

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

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

                  (h) Each Holder of a Class A-1 Certificates, by its acceptance
of such Certificate, hereby agrees that, in the event any distribution is made
to any Holder of such Certificate from amounts paid under the Policy, (i) the
Certificate Insurer shall be subrogated in the manner herein provided to the
rights of the Holder of such Certificate to receive from amounts on deposit in
the Distribution Account the distributions allocable to principal and interest
that would have been distributable to such Holder if no such distribution to
such Holder had been made from amounts paid under the Policy; and (ii) in
addition to the rights of the Holders of the Class A-1 Certificates that the
Certificate Insurer may exercise in accordance with the provisions of Section
12.01, the Certificate Insurer may exercise any option, vote, right, power or
the like with respect to each Class A-1 Certificate for which amounts paid under
the Policy plus interest at the Late Payment Rate thereon from the date such
payment was made are outstanding.

                  Not later than fifteen days after each Distribution Date, 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

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 shall cause to be made an
appropriate entry in the records of the Collection Account that amounts held for
future distribution have been, as permitted by this Section 4.03, used by the
Master Servicer in discharge of any such Advance) or (iii) in the form



                                      125
<PAGE>

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

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



                                      126
<PAGE>

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

                  (b) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee on each Distribution Date as follows: FIRST, in
reduction of interest accrued on and otherwise distributable to the Class CE
Certificates to the extent of Net Monthly Excess Cashflow used to pay principal
on the Class A Certificates and the Mezzanine Certificates under clause (i) of
Section 4.01 hereof; SECOND, in reduction of interest accrued on and otherwise
distributable to the Class CE Certificates to the extent of Net Monthly Excess
Cashflow available for distribution pursuant to clauses (ii) through (vi) of
Section 4.01(a)(4) hereof; and THIRD, in reduction of the Certificate Principal
Balance of the Class CE Certificates (determined after taking into account all
distributions made on the Certificates on such Distribution Date), until the
Certificate Principal Balance thereof has been reduced to zero. If on any
Distribution Date, after all distributions are made by the Trustee pursuant to
Section 4.01 hereof, the aggregate Certificate Principal Balance of the Class A
Certificates, the Mezzanine Certificates and the Class P Certificates exceeds
the sum of the Stated Principal Balance of the Mortgage Loans as of the last day
of the related Due Period (after taking into account prepayments during the
related Prepayment Period), the amount of such excess shall be allocated: FIRST,
to the Class M-10 Certificates, until the Certificate Principal Balance thereof
has been reduced to zero; SECOND, to the Class M-9 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; THIRD, to the
Class M-8 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; FOURTH, to the Class M-7 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; FIFTH, to the Class M-6
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; SIXTH, to the Class M-5 Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; SEVENTH, to the Class M-4
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; EIGHTH, to the Class M-3 Certificates, until the Certificate Principal
Balance thereof has been reduced to zero, NINTH, to the Class M-2 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero and
TENTH, to the Class M-1 Certificates, until the Certificate Principal Balance
thereof has been reduced to zero. All Realized Losses to be allocated to the
Certificate Principal Balances of all Classes on any Distribution Date shall be
so allocated after the actual distributions to be made on such date as provided
above.

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

                  As used herein, an allocation of a Realized Loss on a "PRO
RATA basis" among two or more specified Classes of Certificates means an
allocation on a PRO RATA basis, among the various Classes so specified, to each
such Class of Certificates on the basis of their then outstanding Certificate
Principal Balances prior to giving effect to distributions to be made on such
Distribution Date. All Realized Losses and all other losses allocated to a Class
of Certificates hereunder shall be allocated among the Certificates of such
Class in proportion to the Percentage Interests evidenced thereby.

                  (c) All Realized Losses on the Group I Mortgage Loans shall be
allocated by the Trustee on each Distribution Date, first to REMIC I Regular
Interest I-LT1 and REMIC I Regular Interest I-LT1PF, until the Uncertificated
Balance of each such REMIC I Regular Interest has been reduced to zero; provided
however, with respect to the first three Distribution Dates, all Realized Losses
on the Initial Group I Mortgage Loans shall be allocated to REMIC 1 Regular
Interest I-LT1, until the Uncertificated Balance thereof has been reduced to
zero, and all Realized Losses on the Subsequent Group I Mortgage Loans shall be
allocated to REMIC I Regular Interest I-LT1PF until the Uncertificated Balance
thereof has been reduced to zero. All Realized Losses on the Group II Mortgage
Loans shall be allocated by the Trustee on each Distribution Date, first to
REMIC I Regular Interest I-LT2 and REMIC I Regular Interest I-LT2PF, until the
Uncertificated Balance of each such REMIC I Regular Interest has been reduced to
zero; provided however, with respect to the first three Distribution Dates, all
Realized Losses on the Initial Group II Mortgage Loans shall be allocated to
REMIC I Regular Interest I-LT2, until the Uncertificated Balance thereof has
been reduced to zero, and all Realized Losses on the Subsequent Group II
Mortgage Loans shall be allocated to REMIC I Regular Interest I-LT2PF until the
Uncertificated Balance thereof has been reduced to zero.

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

                                      128
<PAGE>

respectively, until the Uncertificated Balance of REMIC II Regular Interest
II-LTM9 has been reduced to zero; fifth, to the Uncertificated Balances of REMIC
II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM8 and REMIC II
Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC II Regular Interest II-LTM8 has been reduced to zero; sixth, to
the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II
Regular Interest II-LTM7 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC II Regular Interest
II-LTM7 has been reduced to zero; seventh, to the Uncertificated Balances of
REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM6 and REMIC
II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Balance of REMIC II Regular Interest II-LTM6 has been reduced to
zero; eighth, to the Uncertificated Balances of REMIC II Regular Interest
II-LTAA, REMIC II Regular Interest II-LTM5 and REMIC II Regular Interest
II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC
II Regular Interest II-LTM5 has been reduced to zero; ninth, to the
Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular
Interest II-LTM4 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC II Regular Interest
II-LTM4 has been reduced to zero; tenth, to the Uncertificated Balances of REMIC
II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM3 and REMIC II
Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC II Regular Interest II-LTM3 has been reduced to zero; eleventh,
to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II
Regular Interest II-LTM2 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC II Regular Interest
II-LTM2 has been reduced to zero, and twelfth, to the Uncertificated Balances of
REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM1 and REMIC
II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Balance of REMIC II Regular Interest II-LTM1 has been reduced to
zero.

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



                                      129
<PAGE>

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 Commission thereunder, and the Depositor shall sign (or shall cause
another entity acceptable to the Commission to sign) and the Trustee shall file
(via the Commission's Electronic Data Gathering and Retrieval System) such forms
on behalf of the Depositor (or such other entity). The Depositor hereby grants
to the Trustee a limited power of attorney to execute any Form 8-K and file each
such document on behalf of the Depositor. Such power of attorney shall continue
until the earlier of (i) receipt by the Trustee from the Depositor of written
termination of such power of attorney and (ii) the termination of the Trust.
Notwithstanding anything herein to the contrary, the Depositor, and not the
Trustee, shall be responsible for executing each Form 10-K filed on behalf of
the Trust.

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

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



                                      130
<PAGE>

than March 20th of each year (or if such day is not a Business Day, the
immediately preceding Business Day).

                  In addition, the Trustee shall indemnify and hold harmless the
Depositor and its officers, directors and Affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach of the Trustee's obligations under this Section 4.06 or the
Trustee's negligence, bad faith or willful misconduct in connection therewith.
The Depositor shall indemnify and hold harmless the Trustee and its officers,
directors and Affiliates from and against any losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments
and other costs and expenses arising out of or based upon a breach of the
Depositor's obligations under this Section 4.06 or the Depositor's negligence,
bad faith or willful misconduct in connection therewith. If the indemnification
provided for herein is unavailable or insufficient to hold harmless the
Depositor or the Trustee, as applicable, then the other party, in connection
with a breach of its respective obligations under this Section 4.06 or its
respective negligence, bad faith or willful misconduct in connection therewith,
agrees that it shall contribute to the amount paid or payable by the other party
as a result of the losses, claims, damages or liabilities of the other party in
such proportion as is appropriate to reflect the relative fault of the Depositor
on the one hand and the Trustee on the other.

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

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

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

SECTION 4.07      Pre-Funding Accounts.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain two segregated non-interest bearing trust accounts that
are each Eligible Accounts, which shall be titled (i) "Group I Pre-Funding
Account, Deutsche Bank National Trust Company, as Trustee for the registered
holders of Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through
Certificates, Series 2004-R10" (the "Group I Pre-Funding Account") and (ii)
"Group II Pre-Funding Account, Deutsche Bank National Trust Company, as Trustee
for the registered holders of Ameriquest Mortgage Securities Inc., Asset-Backed
Pass-Through Certificates, Series 2004-



                                      131
<PAGE>

R10" (the "Group II Pre-Funding Account"). The Trustee shall, promptly upon
receipt, deposit in the applicable Pre-Funding Account and retain therein the
Original Group I Pre-Funded Amount or the Original Group II Pre-Funding Account,
as applicable, remitted on the Closing Date to the Trustee by the Depositor.
Funds deposited in the Pre-Funding Accounts shall be held in trust by the
Trustee for the Certificateholders and the Certificate Insurer for the uses and
purposes set forth herein.

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

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

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

               (ii) if the amount on deposit in the related Pre-Funding Account
          has not been reduced to zero during the Funding Period, on the day of
          the termination of the Funding Period, the Trustee shall deposit into
          the Distribution Account any amounts remaining in the Pre-Funding
          Account to be held uninvested;

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

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

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

SECTION 4.08      Interest Coverage Accounts.



                                      132
<PAGE>

                  (a) If amounts are required to be deposited in the Interest
Coverage Accounts, no later than the Closing Date, the Trustee shall establish
and maintain a segregated non-interest bearing trust account that is an Eligible
Account, which shall be titled (i) "Group I Interest Coverage Account, Deutsche
Bank National Trust Company, as Trustee for the registered holders of Ameriquest
Securities Inc., Asset-Backed Pass-Through Certificates, Series 2004-R10" (the
"Group I Interest Coverage Account") and (ii) "Group II Pre-Funding Account,
Deutsche Bank National Trust Company, as Trustee for the registered holders of
Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through Certificates,
Series 2004-R10" (the "Group II Pre-Funding Account"). The Trustee shall,
promptly upon receipt, deposit in each Interest Coverage Account and retain
therein the related Interest Coverage Amount, remitted on the Closing Date to
the Trustee by the Depositor. Funds deposited in the Interest Coverage Accounts
shall be held in trust by the Trustee for the Certificateholders and the
Certificate Insurer for the uses and purposes set forth herein

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

                  (c) On each Distribution Date during the Funding Period and on
the last day of the Funding Period, the Trustee shall withdraw from the related
Interest Coverage Account and deposit in the Distribution Account an amount
equal to 30 days' interest on the excess, if any, of the related Original
Pre-Funded Amount, over the aggregate Stated Principal Balance of related
Subsequent Mortgage Loans that both (i) had a Due Date during the Due Period
relating to such Distribution Date and (ii) had a Subsequent Cut-off Date prior
to the first day of the month in which such Distribution Date occurs, at a per
annum rate equal to the weighted average Pass-Through Rate of the related
Offered Certificates for such Distribution Date, with the Pass-Through Rate on
the related Offered Certificates, solely for the purposes of the foregoing
calculation, multiplied by a fraction, the numerator of which is the actual
number of days in the Accrual Period for such Class for such Distribution Date,
and the denominator of which is 30. Such withdrawal and deposit shall be treated
as a contribution of cash by the Master Servicer to REMIC I. Immediately
following any such withdrawal and deposit, and immediately following the
conveyance of any Subsequent Mortgage Loans to the Trust on any Subsequent
Transfer Date, the Trustee shall withdraw from the Interest Coverage Accounts
and remit to the Master Servicer or its designee an amount equal to the excess,
if any, of the amount remaining in such Interest Coverage Account over the
amount that would be required to be withdrawn therefrom (assuming sufficient
funds therein) pursuant to the second preceding sentence on each



                                      133
<PAGE>

subsequent Distribution Date, if any, that shall occur during the Funding Period
or that shall be the Distribution Date immediately following the end of the
Funding Period, if no Subsequent Mortgage Loans were acquired by the Trust Fund
after the end of the Prepayment Period relating to the current Distribution Date
(assuming that LIBOR remains constant at the level of LIBOR applicable to the
calculation of the Pass-Through Rate for the Class A Certificates and Mezzanine
Certificates for the current Distribution Date).

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

SECTION 4.09      [Reserved].

SECTION 4.10      [Reserved].

SECTION 4.11      Net WAC Rate Carryover Reserve Account.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain with itself, as agent for the Trustee, a separate,
segregated trust account titled, "Net WAC Rate Carryover Reserve Account,
Deutsche Bank National Trust Company, as Trustee, in trust for the registered
Holders of Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through
Certificates, Series 2004-R10." The Trustee shall deposit into the Net WAC Rate
Carryover Reserve Account any payments received by it (i) under the Cap
Contracts for the benefit of the Holders of the Adjustable-Rate Certificates and
(ii) pursuant to Section 4.01(a)(4)(iv).

                  (b) On each Distribution Date as to which there is a Net WAC
Rate Carryover Amount payable to the Class A Certificates or the Mezzanine
Certificates, the Trustee has been directed by the Class CE Certificateholders
to, and therefore shall, deposit into the Net WAC Rate Carryover Reserve Account
the amount of such Net WAC Rate Carryover Amount, after taking into account
amounts received under the Cap Contracts, rather than distributing such amounts
to the Class CE Certificateholders. On each such Distribution Date, the Trustee
shall hold all such amounts for the benefit of the Holders of the Class A
Certificates and the Mezzanine Certificates, and shall distribute such amounts
to the Holders of the Class A Certificates and the Mezzanine Certificates in the
amounts and priorities set forth in Section 4.01(a).

                  (c) For federal and state income tax purposes, the Class CE
Certificateholders shall be deemed to be the owners of the Net WAC Rate
Carryover Reserve Account and all amounts deposited into the Net WAC Rate
Carryover Reserve Account shall be treated as amounts distributed by REMIC II to
the Holders of the Class CE Interest and by REMIC III 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 shall be
released by the Trust and distributed



                                      134
<PAGE>

to the Class CE Certificateholders or their designees. The Net WAC Rate
Carryover Reserve Account shall 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 shall not be payments with
respect to a "regular interest" in a REMIC within the meaning of Code Section
860(G)(a)(1).

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

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

                  (f) For federal income tax return and information reporting,
the value assigned to the right of the Holders of the Group I Certificates,
Group II Certificates and the Mezzanine Certificates to receive payments from
the Net WAC Rate Carryover Reserve Account in respect of any Net WAC Rate
Carryover Amount shall be $297,000, $80,000 and $200,000, respectively.

SECTION 5.01      The Certificates.

                  (a) The Certificates in the aggregate shall 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 shall equal the aggregate Stated Principal Balance
of the Mortgage Loans.

                  The Certificates shall be substantially in the forms annexed
hereto as Exhibits A-1 through A-19. The Certificates of each Class shall be
issuable in registered form only, in denominations of authorized Percentage
Interests as described in the definition thereof. Each Certificate shall 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



                                      136
<PAGE>

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

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

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



                                      137
<PAGE>

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

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



                                      138
<PAGE>

without registration under the 1933 Act (other than in connection with (i) the
initial transfer of any such Certificate by the Depositor to an affiliate of the
Depositor, (ii) the transfer of any such Certificate to the issuer under the
Indenture or the indenture trustee under the Indenture or (iii) a transfer of
any such Certificate from the issuer under the Indenture or the indenture
trustee under the Indenture to the Depositor or an Affiliate of the Depositor),
then the Certificate Registrar shall refuse to register such transfer unless it
receives (and upon receipt, may conclusively rely upon) a certificate from the
Certificateholder desiring to effect such transfer and a certificate from such
Certificateholder's prospective transferee (which in the case of the Book-Entry
Certificates, the Certificateholder and the Certificateholder's prospective
transferee shall be deemed to have represented such certification), to the
effect that, among other things, the transfer is being made to a qualified
institutional buyer as defined in Rule 144A under the Securities Act in
accordance with Rule 144A. Any Certificateholder desiring to effect the transfer
of a Class M-10 Certificate, Class CE Certificate, Class P Certificate or
Residual Certificate shall, and does hereby agree to, indemnify the Trustee, the
Depositor, the Certificate Registrar and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  Notwithstanding the foregoing, no certification or Opinion of
Counsel described in this Section 5.02(b) shall 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.

                  (c) No transfer of a Class CE Certificate, Class P Certificate
or Residual Certificate or any interest therein shall be made to any Plan
subject to ERISA or Section 4975 of the Code, any Person acting, directly or
indirectly, on behalf of any such Plan or any Person acquiring such Certificates
with "Plan Assets" of a Plan within the meaning of the Department of Labor
regulation promulgated at 29 C.F.R. ss. 2510.3-101 ("Plan Assets"), as certified
by such transferee in the form of Exhibit G, unless the Trustee is provided with
an Opinion of Counsel for the benefit of the Trust Fund, the Depositor, the
Trustee, the NIMS Insurer, the Certificate Insurer and the Master Servicer and
on which they may rely, which shall be to the effect that the purchase and
holding of such Certificates is permissible under applicable law, shall not
constitute or result in any non-exempt prohibited transaction under ERISA or
Section 4975 of the Code and shall not subject the Depositor, the Master
Servicer, the NIMS Insurer, the Certificate Insurer, the Trustee or the Trust
Fund to any obligation or liability (including obligations or liabilities under
ERISA or Section 4975 of the Code) in addition to those undertaken in this
Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
the Master Servicer, the NIMS Insurer, the Certificate Insurer, the Trustee or
the Trust Fund. Neither an Opinion of Counsel nor any certification shall be
required in connection with (i) the initial transfer of any such Certificate by
the Depositor to an affiliate of the Depositor, (ii) the transfer of any such
Certificate to the issuer under the Indenture or the indenture trustee under the
Indenture or (iii) a transfer of any such Certificate from the issuer under the
Indenture or the indenture trustee under the Indenture to the Depositor or an
Affiliate of the Depositor (in which case such transferee shall be deemed to
have represented that it is not purchasing with 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.



                                      139
<PAGE>

                  Each beneficial owner of the Mezzanine Certificates or any
interest therein shall be deemed to have represented, by virtue of its
acquisition or holding of that Certificate or interest therein, that either (i)
it is not a Plan or acting, directly or indirectly, on behalf of a Plan or with
Plan Assets, (ii) for Mezzanine Certificates other than the Class M-10
Certificates it has acquired and is holding such Mezzanine Certificates (other
than the Class M-10 Certificates) in reliance on the Underwriters' Exemption,
and that it understands that there are certain conditions to the availability of
the Underwriters' Exemption, including that the Certificates (other than the
Class M-10 Certificates) must be rated, at the time of purchase, not lower than
"BBB-" (or its equivalent) by Moody's, Fitch or S&P or (iii) (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 paragraphs, the next preceding
permitted beneficial owner shall 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, the Certificate Insurer, and the
Trust Fund from and against any and all liabilities, claims, costs or expenses
incurred by those parties as a result of that acquisition or holding.

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

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

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



                                      140
<PAGE>

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

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

                  (B) If any purported Transferee shall become a Holder of a
         Residual Certificate in violation of the restrictions in this Section
         5.02(d) and to the extent that the retroactive restoration of the
         rights of the Holder of such Residual Certificate as described in
         clause (iii)(A) above shall be invalid, illegal or unenforceable, then
         the Certificate Registrar shall have the right, without notice to the
         Holder or any prior Holder



                                      141
<PAGE>

         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, shall 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:

                  (A) written notification from each Rating Agency to the effect
         that the modification, addition to or elimination of such provisions
         shall 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 shall not cause any Trust REMIC to cease
         to qualify as a REMIC and shall not cause any Trust REMIC, as the case
         may be, to be subject to an entity-level tax caused by the Transfer of
         any Residual Certificate to a Person that is not a Permitted Transferee
         or (y) a Person other than the prospective transferee to be subject to
         a REMIC-tax caused by the Transfer of a Residual Certificate to a
         Person that is not a Permitted Transferee.

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

                  (e) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Trustee maintained for such purpose pursuant to Section 8.12, the Trustee shall
execute and the Certificate Registrar shall authenticate



                                      142
<PAGE>

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, the Class R-II Interest and the Class R-III
Interest, respectively, in each case that was evidenced by the Class R
Certificate being exchanged and (ii) with respect to each Class R-X Certificate,
the Holder thereof may exchange, in the manner described above, such Class R-X
Certificate for two separate Certificates, each representing such Holder's
respective Percentage Interest in the Class R-IV Interest and the Class R-V
Interest, respectively, in each case that was evidenced by the Class R-X
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 shall cause the Certificate Registrar (unless
the Trustee is acting as Certificate Registrar) to provide notice to the Trustee
of each transfer of a Certificate and to provide the Trustee with an updated
copy of the Certificate Register on the first Business Day in March and August
of each year, commencing in March 2005.

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

SECTION 5.03      Mutilated, Destroyed, Lost or Stolen Certificates.

                  If (i) any mutilated Certificate is surrendered to the Trustee
or the Certificate Registrar, or the Trustee and the Certificate Registrar
receive evidence to their satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee, the NIMS Insurer, the
Certificate Insurer and the Certificate Registrar such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
actual knowledge by the



                                      143
<PAGE>

Trustee or the Certificate Registrar that such Certificate has been acquired by
a bona fide purchaser or the Trustee shall execute and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of the same Class and of like denomination and Percentage Interest.
Upon the issuance of any new Certificate under this Section, the Trustee may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Certificate Registrar) connected therewith. Any
replacement Certificate issued pursuant to this Section shall constitute
complete and indefeasible evidence of ownership in the applicable REMIC created
hereunder, as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

SECTION 5.04      Persons Deemed Owners.

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

                      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 shall 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 shall 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 shall obtain and preserve its qualification to do business as a
foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of this Agreement, the
Certificates or any of the Mortgage Loans and to perform its respective duties
under this Agreement.

                  The Depositor or the Master Servicer may be merged or
consolidated with or into any Person, or transfer all or substantially all of
its assets to any Person, in which case any Person resulting from any merger or
consolidation to which the Depositor or the Master Servicer shall be a party, or
any Person succeeding to the business of the Depositor or the Master Servicer,
shall be the successor of the Depositor or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Master Servicer shall be qualified to service mortgage loans on behalf of
Fannie Mae or Freddie Mac; and provided further that the Rating Agencies'
ratings of the Class A Certificates (without regard to the Policy) and the
Mezzanine Certificates in effect immediately prior to such merger or
consolidation shall 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 would otherwise be imposed by reason of willful misfeasance, bad
faith or negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder. The Depositor, the NIMS Insurer,
the Master Servicer or the Trustee and any director, officer, employee or agent
of the Depositor, the NIMS Insurer, the Master Servicer or the Trustee may rely
in good faith on any document of any kind which, PRIMA FACIE, is properly
executed and submitted by any Person respecting any matters arising hereunder.

                  The Depositor, the NIMS Insurer, the Master Servicer and any
director, officer, employee or agent of the Depositor, the NIMS Insurer, or the
Master Servicer shall be indemnified and held harmless by the Trust Fund against
any loss, liability or expense incurred in connection with any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense relating to any specific Mortgage Loan or Mortgage Loans (except as
any such loss, liability or expense shall be otherwise reimbursable pursuant to
this Agreement) or, in the case of the Depositor and the Master Servicer, any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. None of the Depositor, the NIMS
Insurer or the Master Servicer shall be under any obligation to appear in,
prosecute or defend any legal action unless such action is related to its
respective duties under this Agreement and, in its opinion, does not involve it
in any expense or liability; provided, however, that each of the Depositor, the
NIMS Insurer and the Master Servicer may in its discretion undertake any such
action which it may deem necessary or desirable with respect to this Agreement
and the rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In such event, unless the Depositor or the Master
Servicer acts without the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights (which consent shall not be necessary in the case
of litigation or other legal action by either to enforce their respective rights
or defend themselves hereunder), the legal expenses and costs of such action and
any liability resulting therefrom (except any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder) shall be expenses, costs and liabilities of
the Trust Fund, and the Depositor, the NIMS Insurer and the Master Servicer
shall be entitled to be reimbursed therefor from the Collection Account as and
to the extent provided in Section 3.05, any such right of reimbursement being
prior to the rights of the Certificateholders to receive any amount in the
Collection Account.

SECTION 6.04      Limitation on Resignation of the Master Servicer.

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

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

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

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



                                      147
<PAGE>

Agreement and may, but is not obligated to, perform, or cause a designee to
perform, any defaulted obligation of the Master Servicer under this Agreement or
exercise the rights of the Master Servicer under this Agreement; provided that
the Master Servicer shall not be relieved of any of its obligations under this
Agreement by virtue of such performance by the Depositor or its designee. The
Depositor shall not have any responsibility or liability for any action or
failure to act by the Master Servicer and is not obligated to supervise the
performance of the Master Servicer under this Agreement or otherwise.

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

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

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

                  (b) As part of its servicing activities hereunder, the Master
Servicer (except as otherwise provided in the last sentence of this paragraph),
for the benefit of the Trustee, the



                                      148
<PAGE>

Certificate Insurer and the Certificateholders, shall enforce the obligations of
each Sub-Servicer under the related Sub-Servicing Agreement and of the Seller
under the Mortgage Loan Purchase Agreement, including, without limitation, any
obligation to make advances in respect of delinquent payments as required by a
Sub-Servicing Agreement, or to purchase a Mortgage Loan on account of missing or
defective documentation or on account of a breach of a representation, warranty
or covenant, as described in Section 2.03(a). Such enforcement, including,
without limitation, the legal prosecution of claims, termination of
Sub-Servicing Agreements, and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, and shall be reimbursed therefor only (i) from a
general recovery resulting from such enforcement, to the extent, if any, that
such recovery exceeds all amounts due in respect of the related Mortgage Loans
or (ii) from a specific recovery of costs, expenses or attorneys' fees against
the party against whom such enforcement is directed. Enforcement of the Mortgage
Loan Purchase Agreement against the Seller shall be effected by the Master
Servicer to the extent it is not the Seller, and otherwise by the Trustee, in
accordance with the foregoing provisions of this paragraph.

SECTION 6.07      Successor Sub-Servicers.

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

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

SECTION 6.08      Liability of the Master Servicer.

                  Notwithstanding any Sub-Servicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Master Servicer and a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall remain obligated and
primarily liable to the Trustee and the Certificateholders for the servicing and
administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
Sub-Servicing Agreements or arrangements or by virtue of indemnification from
the Sub-Servicer and to the same extent and under the same terms and conditions
as if the Master Servicer alone were servicing and administering the Mortgage
Loans. The Master Servicer shall be entitled to enter into any agreement with a
Sub-Servicer for indemnification of the Master Servicer by such Sub-



                                      149
<PAGE>

Servicer and nothing contained in this Agreement shall be deemed to limit or
modify such indemnification.

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

                  Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Master Servicer alone, and the NIMS Insurer, the Certificate Insurer, the
Trustee and Certificateholders shall not be deemed parties thereto and shall
have no claims, rights, obligations, duties or liabilities with respect to the
Sub-Servicer except as set forth in Section 6.10. The Master Servicer shall be
solely liable for all fees owed by it to any Sub-Servicer, irrespective of
whether the Master Servicer's compensation pursuant to this Agreement is
sufficient to pay such fees.

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

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

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

SECTION 6.11      Sub-Servicing Accounts.

                  In those cases where a Sub-Servicer is servicing a Mortgage
Loan pursuant to a Sub-Servicing Agreement, the Sub-Servicer shall be required
to establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be



                                      150
<PAGE>

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.

                                  ARTICLE VII

                                     DEFAULT

SECTION 7.01      Master Servicer Events of Default.

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

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

                  (ii) any failure on the part of the Master Servicer duly to
         observe or perform in any material respect any of the covenants or
         agreements on the part of the Master Servicer contained in the
         Certificates or in this Agreement (or, if the Master Servicer is the
         Seller, the failure of the Seller to repurchase a Mortgage Loan as to
         which a breach has been established that requires a repurchase pursuant
         to the terms of Section 7 of the Mortgage Loan Purchase Agreement)
         which continues unremedied for a period of 45 days after the earlier of
         (i) the date on which written notice of such failure, requiring the
         same to be remedied, shall have been given to the Master Servicer by

         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

         entered against the Master Servicer and if such proceeding is being
         contested by the Master Servicer in good faith, such decree or order
         shall have remained in force undischarged or unstayed for a period of
         60 days or results in the entry of an order for relief or any such
         adjudication or appointment; or

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

                  (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 under 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, at the written direction of
the Holders of Certificates entitled to at least 51% of Voting Rights, or at the
direction of the NIMS Insurer, the Trustee shall, by notice in writing to the
Master Servicer and the Depositor, terminate all of the rights and obligations
of the Master Servicer in its capacity as Master Servicer under this Agreement,
to the extent permitted by law, and in and to the Mortgage Loans and the
proceeds thereof. If a Master Servicer Event of Default described in clause
(vii) hereof shall occur, the Trustee shall, by notice in writing to the Master
Servicer and the Depositor, terminate all of the rights and obligations of the
Master Servicer in its capacity as Master Servicer under this Agreement and in
and to the Mortgage Loans and the proceeds thereof and the Trustee as successor
Master Servicer or a successor Master Servicer appointed in accordance with
Section 7.02, shall immediately make such Advance(which Advance shall be part of
Available Funds for such Distribution Date) and assume, pursuant to Section
7.02, the duties of a successor Master Servicer. On or after the receipt by the
Master Servicer of such written notice, all authority and power of the Master
Servicer under this Agreement, whether with respect to the Certificates (other
than as a Holder of any Certificate) or the Mortgage Loans or otherwise, shall
pass to and be vested in the Trustee pursuant to and under this Section and,
without limitation, the Trustee is hereby authorized and empowered, as
attorney-in-fact or otherwise, to execute and deliver on behalf of and at the
expense of the Master Servicer, any and



                                      152
<PAGE>

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 Escrow 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 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



                                      153
<PAGE>

Trustee as successor to the Master Servicer hereunder; provided, however, it is
understood and acknowledged by the parties that there shall be a period of
transition (not to exceed 90 days) before the servicing transfer is fully
effected. As compensation therefor, effective from and after the time the Master
Servicer receives a notice of termination or immediately upon assumption of the
obligations to make Advances, the Trustee shall be entitled to the Servicing Fee
and all funds relating to the Mortgage Loans to which the Master Servicer would
have been entitled if it had continued to act hereunder (other than amounts
which were due or would become due to the Master Servicer prior to its
termination or resignation). Notwithstanding the above and subject to the next
paragraph, the Trustee may, if it shall be unwilling to so act, or shall, if it
is unable to so act or if it is prohibited by law from making advances regarding
delinquent mortgage loans, or if the Holders of Certificates entitled to at
least 51% of the Voting Rights or the NIMS Insurer so request in writing to the
Trustee promptly appoint or petition a court of competent jurisdiction to
appoint, an established mortgage loan servicing institution acceptable to each
Rating Agency (with confirmation from the Rating Agencies that such appointment
shall not result in the reduction or withdrawal of the rating of any outstanding
Class of Certificates (without regard to the Policy)) and acceptable to the NIMS
Insurer and having a net worth of not less than $15,000,000 as the successor to
the Master Servicer under this Agreement in the assumption of all or any part of
the responsibilities, duties or liabilities of the Master Servicer under this
Agreement. No appointment of a successor to the Master Servicer under this
Agreement shall be effective until the assumption by the successor of all of the
Master Servicer's responsibilities, duties and liabilities hereunder. In
connection with such appointment and assumption described herein, the Trustee
may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
Master Servicer as such hereunder. The Depositor, the Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Pending appointment of a successor to the Master
Servicer under this Agreement, the Trustee shall act in such capacity as
hereinabove provided.

                  Upon removal or resignation of the Master Servicer, the
Trustee, with the cooperation of the Depositor, (x) shall solicit bids for a
successor Master Servicer as described below and (y) pending the appointment of
a successor Master Servicer as a result of soliciting such bids, shall serve as
Master Servicer of the Mortgage Loans serviced by such predecessor Master
Servicer. The Trustee shall solicit, by public announcement, bids from housing
and home finance institutions, banks and mortgage servicing institutions meeting
the qualifications set forth above (including the Trustee or any affiliate
thereof) (including that such mortgage loan servicing institution shall 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 shall 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



                                      154
<PAGE>

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

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



                                      155
<PAGE>

Servicing Advances in accordance with Section 3.05(a)(ii), Section 3.05(a)(iii),
Section 3.05(a)(v) or Section 3.05(a)(vii).

SECTION 7.03      Notification to Certificateholders.

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

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

SECTION 7.04      Waiver of Master Servicer Events of Default.

                  The Holders representing at least 66% of the Voting Rights
(with the consent of the NIMS Insurer) evidenced by all Classes of Certificates
affected by any default or Master Servicer Event of Default hereunder may waive
such default or Master Servicer Event of Default; provided, however, that a
default or Master Servicer Event of Default under clause (i) or (vii) of Section
7.01 may be waived only by all of the Holders of the Regular Certificates (with
the consent of the NIMS Insurer). Upon any such waiver of a default or Master
Servicer Event of Default, such default or Master Servicer Event of Default
shall cease to exist and shall be deemed to have been remedied for every purpose
hereunder. No such waiver shall extend to any subsequent or other default or
Master Servicer Event of Default or impair any right consequent thereon except
to the extent expressly so waived.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

SECTION 8.01      Duties of Trustee.

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

                  The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically



                                      156
<PAGE>

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 shall provide notice thereof to the Certificateholders, the Certificate
Insurer and the NIMS Insurer.

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

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

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

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

                  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:



                                      157
<PAGE>

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

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

               (iii) The Trustee shall not be under any obligation to exercise
          any of the trusts or powers vested in it by this Agreement or to
          institute, conduct or defend any litigation hereunder or in relation
          hereto at the request, order or direction of any of the
          Certificateholders or the NIMS Insurer, pursuant to the provisions of
          this Agreement, unless such Certificateholders or the NIMS Insurer, as
          applicable, shall have offered to the Trustee security or indemnity
          reasonably satisfactory to it against the costs, expenses and
          liabilities which may be incurred therein or thereby; nothing
          contained herein shall, however, relieve the Trustee of the
          obligation, upon the occurrence of a Master Servicer Event of Default
          (which has not been cured or waived), to exercise such of the rights
          and powers vested in it by this Agreement, and to use the same degree
          of care and skill in their exercise as a prudent person would exercise
          or use under the circumstances in the conduct of such person's own
          affairs;

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

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

                                      158
<PAGE>

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

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

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

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

                  The recitals contained herein and in the Certificates (other
than the signature of the Trustee, the authentication of the Certificate
Registrar on the Certificates, the acknowledgments of the Trustee contained in
Article II and the representations and warranties of the Trustee in Section
8.13) shall be taken as the statements of the Depositor and the Trustee assumes
no responsibility for their correctness. The Trustee makes no representations or
warranties as to the validity or sufficiency of this Agreement (other than as
specifically set forth with respect to such party in Section 8.13) or of the
Certificates (other than the signature of the Trustee and authentication of the
Certificate Registrar on the Certificates) or of any Mortgage Loan or related
document. The Trustee shall not be accountable for the use or application by the
Depositor of any of the Certificates or of the proceeds of such Certificates, or
for the use or application of any funds paid to the Depositor or the Master
Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the
Collection Account by the Master Servicer, other than, subject to Section 8.01,
any funds held by or on behalf of the Trustee in accordance with Section 3.04.

SECTION 8.04      Trustee May Own Certificates.

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

SECTION 8.05      Trustee's Fees and Expenses.

                  (a) The Trustee shall withdraw from the Distribution Account
on each Distribution Date and pay to itself the Trustee Fee and, to the extent
that the funds therein are at any time insufficient for such purpose, the
Depositor shall pay such fees. The Trustee, or any



                                      159
<PAGE>

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 Seller, the Master Servicer or any
Affiliate of the foregoing) organized and doing business under the laws of any
state or the United States of America, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by federal or state
authority. If such corporation or association publishes reports of conditions at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section the
combined capital and surplus of such corporation or association shall be deemed
to be its combined capital and surplus as set forth in its most recent report of
conditions so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 8.07.



                                      160
<PAGE>

SECTION 8.07      Resignation and Removal of the Trustee.

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

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

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

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

SECTION 8.08      Successor Trustee.

                  Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer, the
Certificate Insurer and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the



                                      161
<PAGE>

resignation or removal of the predecessor trustee shall become effective and
such successor trustee without any further act, deed or conveyance, shall become
fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with the like effect as if originally named as trustee
herein. The predecessor trustee shall deliver to the successor trustee all
Mortgage Files and related documents and statements, as well as all moneys, held
by it hereunder (other than any Mortgage Files at the time held by a Custodian,
which Custodian shall become the agent of any successor trustee hereunder), and
the Depositor and the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for more
fully and certainly vesting and confirming in the successor trustee all such
rights, powers, duties and obligations.

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

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

SECTION 8.09      Merger or Consolidation of Trustee.

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

SECTION 8.10      Appointment of Co-Trustee or Separate Trustee.

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



                                      162
<PAGE>

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

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

                  Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article VIII. Each separate trustee and co-trustee, upon
its acceptance of the trust conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with the
Trustee or separately, as may be provided therein, subject to all the provisions
of this Agreement, specifically including every provision of this Agreement
relating to the conduct of, affecting the liability of, or affording protection
to, the Trustee. Every such instrument shall be filed with the Trustee and a
copy thereof given to the Depositor, the Master Servicer, the Certificate
Insurer and the NIMS Insurer.

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

SECTION 8.11      Appointment of Custodians.

                  The Trustee may, with the consent of the Depositor and the
Master Servicer appoint one or more Custodians to hold all or a portion of the
Mortgage Files as agent for the Trustee, by entering into a Custodial Agreement.
The appointment of any Custodian may at any time be terminated and a substitute
Custodian appointed therefor upon the reasonable request of the Master Servicer
to the Trustee, the consent to which shall not be unreasonably withheld. The
Trustee shall pay any and all fees and expenses of any Custodian in accordance
with each Custodial Agreement (provided that if expenses of the kind that would
be reimbursable to the Trustee pursuant to Section 8.05 if incurred by the
Trustee are incurred by the Custodian, the



                                      163
<PAGE>

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

SECTION 8.12      Appointment of Office or Agency.

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

SECTION 8.13      Representations and Warranties of the Trustee.

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

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

               (ii) The execution and delivery of this Agreement by it, and the
          performance and compliance with the terms of this Agreement by it,
          shall 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


                                      164
<PAGE>

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

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

                                   ARTICLE IX

                                   TERMINATION

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

                  (a) Subject to Section 9.02, the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer and
the Trustee (other than the obligations of the Master Servicer to the Trustee
pursuant to Section 8.05 and of the Master Servicer to provide for and the
Trustee to make payments in respect of the REMIC I Regular Interests, the REMIC
II Regular Interests or the Classes of Certificates as hereinafter set forth)
shall terminate upon payment to the Certificateholders and the deposit of all
amounts held by or on behalf of the Trustee and required hereunder to be so paid
or deposited on the Distribution Date coinciding with or following the earlier
to occur of (i) the purchase by the Terminator (as defined below) of all
Mortgage Loans and each REO Property remaining in REMIC I and (ii) the final
payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan or REO Property remaining in REMIC I; provided, however, that in
no event shall the trust created hereby continue beyond the expiration of 21
years from the death of the last survivor of the descendants of Joseph P.
Kennedy, the late ambassador of the United States to the Court of St. James,
living on the date hereof. The purchase by the Terminator of all Mortgage Loans
and each REO Property remaining in REMIC I shall be at a price (the "Termination
Price") equal to greater of (A) the aggregate fair market value of all of the
assets of REMIC I and (B) the sum of the Stated Principal Balance of the
Mortgage Loans (after giving effect to scheduled payments of principal due
during the related Due Period, to the extent received or advanced, and
unscheduled collections of principal received during the related Prepayment
Period) and the appraised fair market value of the REO Properties plus accrued
interest through the end of the calendar month preceding the month of the final
Distribution Date and any unreimbursed Advances and Servicing Advances(in the
case of fair market values required to be determined under (A) or (B) above, as
determined by the Terminator, the Trustee and, if the Terminator is not the NIMS




                                      165
<PAGE>

Insurer, the NIMS Insurer, as of the close of business on the third Business Day
next preceding the date upon which notice of any such termination is furnished
to Certificateholders pursuant to the third paragraph of this Section 9.01);
provided, however, such option may only be exercised if the Termination Price is
sufficient to pay (i) any amounts owed to the Certificate Insurer under the
Insurance Agreement and (ii) all interest accrued on, as well as amounts
necessary to retire the note balance of, each class of notes issued pursuant to
the Indenture and any amounts owed to the NIMS Insurer at the time the option is
exercised. If a termination pursuant to this Section 9.01(a) or Section 9.01(b)
will result in a claim under the Policy or if any amount owed to the Certificate
Insurer will not be fully reimbursed after such termination, the consent of the
Certificate Insurer shall be required prior to the Terminator exercising such
option.

                  (b) The Master Servicer (or if the Master Servicer fails to
exercise such right, the NIMS Insurer) shall have the right (the party
exercising such right, the "Terminator"), to purchase all of the Mortgage Loans
and each REO Property remaining in REMIC I pursuant to clause (i) of the
preceding paragraph no later than the Determination Date in the month
immediately preceding the Distribution Date on which the Certificates shall be
retired; provided, however, that the Terminator may elect to purchase all of the
Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i)
above only (A) if the aggregate Stated Principal Balance of the Mortgage Loans
and each REO Property remaining in the Trust Fund at the time of such election
is less than 10% of the sum of (x) the aggregate Stated Principal Balance of the
Initial Mortgage Loans as of the Cut-off Date and (y) the Original Pre-Funded
Amounts and (B) if the Terminator is the Master Servicer and is an affiliate of
the Seller, the Master Servicer shall have delivered to the Trustee, the
Certificate Insurer and the NIMS Insurer a written certification that the
burdens of servicing the Mortgage Loans and REO Properties remaining in REMIC I
exceed the benefits of the Servicing Fees that would be realized by the Master
Servicer if it continued to service such assets on behalf of the Trust Fund. By
acceptance of the Residual Certificates, the Holders of the Residual
Certificates agree, in connection with any termination hereunder, to pledge any
amounts in excess of par, and to the extent received in respect of such
termination, to pay any such amounts to the Holders of the Class CE
Certificates.

                  (c) Notice of the liquidation of the REMIC I Regular Interests
shall be given promptly by the Trustee by letter to Certificateholders and the
Certificate Insurer mailed (a) in the event such notice is given in connection
with the purchase of the Mortgage Loans and each REO Property by the Terminator,
not earlier than the 15th day and not later than the 25th day of the month next
preceding the month of the final distribution on the Certificates or (b)
otherwise during the month of such final distribution on or before the
Determination Date in such month, in each case specifying (i) the Distribution
Date upon which the Trust Fund shall terminate and final payment in respect of
the REMIC I Regular Interests, the REMIC II Regular Interests and the
Certificates shall be made upon presentation and surrender of the related
Certificates at the office of the Trustee therein designated, (ii) the amount of
any such final payment, (iii) that no interest shall accrue in respect of the
REMIC I Regular Interests, the REMIC II Regular Interests or the Certificates
from and after the Interest Accrual Period relating to the final Distribution
Date therefor and (iv) that the Record Date otherwise applicable to such
Distribution Date is not applicable, payments being made only upon presentation
and surrender of the Certificates at the office of the Trustee. The Trustee
shall give such notice to the Certificate Registrar at the time such notice is
given to Certificateholders. In the event such notice is given in connection
with



                                      166
<PAGE>

the purchase of all of the Mortgage Loans and each REO Property remaining in
REMIC I by the Terminator, the Terminator shall deliver to the Trustee for
deposit in the Distribution Account not later than the last Business Day
preceding the final Distribution Date on the Certificates an amount in
immediately available funds equal to the above-described purchase price. Upon
certification to the Trustee by a Servicing Officer of the making of such final
deposit, the Trustee shall promptly release or cause to be released to the
Terminator the Mortgage Files for the remaining Mortgage Loans, and the Trustee
shall execute all assignments, endorsements and other instruments necessary to
effectuate such transfer.

                  (d) Upon presentation of the Certificates by the
Certificateholders on the final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates the
amount otherwise distributable on such Distribution Date in accordance with
Section 4.01 in respect of the Certificates so presented and surrendered. Any
funds not distributed to any Holder or Holders of Certificates being retired on
such Distribution Date because of the failure of such Holder or Holders to
tender their Certificates shall, on such date, be set aside and held in trust by
the Trustee and credited to the account of the appropriate non-tendering Holder
or Holders. If any Certificates as to which notice has been given pursuant to
this Section 9.01 shall not have been surrendered for cancellation within six
months after the time specified in such notice, the Trustee shall mail a second
notice to the remaining non-tendering Certificateholders to surrender their
Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such
Certificates shall not have been surrendered for cancellation, the Trustee
shall, directly or through an agent, mail a final notice to remaining related
non-tendering Certificateholders concerning surrender of their Certificates. The
costs and expenses of maintaining the funds in trust and of contacting such
Certificateholders shall 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 first reimburse any amounts
which were paid by the Certificate Insurer under the Policy to the Certificate
Insurer (but only if the non-surrendered Certificates are Insured Certificates)
and second, shall pay to the Representative all remaining 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

<PAGE>

          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.

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 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 shall
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



                                      169

purposes as to the valuations and issue prices of the Certificates, including,
without limitation, the price, yield, prepayment assumption and projected cash
flow of the Certificates.

                  (f) The Trustee shall take such action and shall cause each
REMIC created hereunder to take such action as shall be necessary to create or
maintain the status thereof as a REMIC under the REMIC Provisions (and the
Master Servicer shall assist it, to the extent reasonably requested by it). The
Trustee shall not take any action, cause the Trust Fund to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of any Trust REMIC as a REMIC or (ii) result in the imposition of a tax
upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) (either such
event, an "Adverse REMIC Event") unless the Trustee, the Certificate Insurer and
the NIMS Insurer have received an Opinion of Counsel, addressed to the Trustee,
the NIMS Insurer and the Certificate Insurer (at the expense of the party
seeking to take such action but in no event at the expense of the Trustee) to
the effect that the contemplated action shall not, with respect to any Trust
REMIC, endanger such status or result in the imposition of such a tax, nor shall
the Master Servicer take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee, the Certificate Insurer and the NIMS Insurer
has advised it in writing that it has received an Opinion of Counsel to the
effect that an Adverse REMIC Event could occur with respect to such action. In
addition, prior to taking any action with respect to any Trust REMIC or the
respective assets of each, or causing any Trust REMIC to take any action, which
is not contemplated under the terms of this Agreement, the Master Servicer shall
consult with the Trustee, the NIMS Insurer, the Certificate Insurer or its
designee, in writing, with respect to whether such action could cause an Adverse
REMIC Event to occur with respect to any Trust REMIC, and the Master Servicer
shall not take any such action or cause any Trust REMIC to take any such action
as to which the Trustee, the Certificate Insurer or the NIMS Insurer has advised
it in writing that an Adverse REMIC Event could occur. The Trustee, the
Certificate Insurer or the NIMS Insurer may consult with counsel to make such
written advice, and the cost of same shall be borne by the party seeking to take
the action not permitted by this Agreement, but in no event shall such cost be
an expense of the Trustee. At all times as may be required by the Code, the
Master Servicer on behalf of the Trustee shall ensure that substantially all of
the assets of any Trust REMIC shall consist of "qualified mortgages" as defined
in Section 860G(a)(3) of the Code and "permitted investments" as defined in
Section 860G(a)(5) of the Code.

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

                                      170
<PAGE>

or otherwise (iii) against amounts on deposit in the Distribution Account and
shall be paid by withdrawal therefrom.

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

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

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

                  (k) Neither the Trustee nor the Master Servicer shall enter
into any arrangement by which any Trust REMIC shall receive a fee or other
compensation for services nor permit any such REMIC to receive any income from
assets other than the Mortgage Pool which are deemed to constitute "qualified
mortgages" as defined in Section 860G(a)(3) of the Code or "permitted
investments" as defined in Section 860G(a)(5) of the Code.

SECTION 10.02     Prohibited Transactions and Activities.

                  None of the Depositor, the Master Servicer or the Trustee
shall sell, dispose of or substitute for any of the Mortgage Loans (except in
connection with (i) the foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of REMIC I, (iii) the termination of
REMIC I pursuant to Article IX of this Agreement, (iv) a substitution pursuant
to Article II of this Agreement or (v) a purchase of Mortgage Loans pursuant to
Article II or III of this Agreement), or acquire any assets for any Trust REMIC
(other than REO Property acquired in respect of a defaulted Mortgage Loan), or
sell or dispose of any investments in the Collection Account or the Distribution
Account for gain, or accept any contributions to any Trust REMIC after the
Closing Date (other than a Qualified Substitute Mortgage Loan delivered in
accordance with Section 2.03), unless it has received an Opinion of Counsel,
addressed to the Trustee, the Certificate Insurer and the NIMS Insurer (at the
expense of the party seeking to cause such sale, disposition, substitution,
acquisition or contribution but in no event at the expense of the Trustee) that
such sale, disposition, substitution, acquisition or contribution shall not (a)
affect adversely the status of any Trust REMIC as a REMIC or (b) cause any Trust
REMIC to be subject to a tax on "prohibited transactions" or "contributions"
pursuant to the REMIC Provisions.

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

                  (b) The Master Servicer agrees to indemnify the Trust Fund,
the Certificate Insurer, the NIMS Insurer, the Depositor and the Trustee for any

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.

                                   ARTICLE XI

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

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



                                      172

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 Master Servicer and the Trustee from the Rating Agencies
that such action shall not result in the reduction or withdrawal of the rating
of any outstanding Class of Certificates (without regard to the Policy) 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

any Affiliate thereof shall be entitled to Voting Rights with respect to matters
affecting such Certificates.

                  Notwithstanding the foregoing, any amendment to this Agreement
shall require the prior written consent of the Certificate Insurer if such
amendment adversely affects in any respect the rights or interests of the
Certificate Insurer or of the Insured Certificates (without regard to the
Policy). The Master Servicer shall send a copy of any proposed amendment to this
Agreement to the Certificate Insurer prior to execution of the amendment. The
Certificate Insurer shall notify the Trustee in writing, within a reasonable
time following its receipt of a copy of the proposed amendment, whether the
Certificate Insurer has determined that its consent to such amendment is
required.

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

                  Notwithstanding any of the other provisions of this Section
11.01, none of the Depositor, the Master Servicer or the Trustee shall enter
into any amendment of this Agreement that would significantly change the
permitted activities of the Trust Fund without the consent of the NIMS Insurer,
the Certificate Insurer and the Holders of Certificates that represent more than
50% of the aggregate Certificate Principal Balance of all Certificates.

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

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 to approve the particular form of
any proposed amendment, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable regulations as the Trustee may prescribe.

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.

all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be

                  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

constitute but one and the same instrument.

SECTION 11.03     Limitation on Rights of Certificateholders.

                  The death or incapacity of any Certificateholder shall not

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

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

                  No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless (i)
such Holder previously shall have given to the Trustee and the Certificate
Insurer a written notice of default and of the continuance thereof, as
hereinbefore provided, and (ii) the Holders of Certificates entitled to at least
25% of the Voting Rights shall have made written request upon the Trustee to
institute such action, suit or proceeding in the name of the Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity



                                      174
<PAGE>

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

SECTION 11.04     Governing Law.

SECTION 11.08     Article and Section References.

                  All article and section references used in this Agreement,
unless otherwise provided, are to articles and sections in this Agreement.

SECTION 11.09     Grant of Security Interest.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Depositor to the Trustee be, and be
construed as, a sale of the Mortgage Loans by the Depositor and not a pledge of
the Mortgage Loans by the Depositor to secure a debt or other obligation of the
Depositor or the Seller. However, in the event that, notwithstanding the
aforementioned intent of the parties, the Mortgage Loans are held to be property
of the Depositor or the Seller, then, (a) it is the express intent of the
parties that such conveyance be deemed a pledge of the Mortgage Loans by the
Depositor to the Trustee to secure a debt or other obligation of the Depositor
or the Seller and (b)(1) this Agreement shall also be deemed to be a security
agreement within the meaning of Articles 8 and 9 of the Uniform Commercial Code
as in effect from time to time in the State of New York; (2) the conveyance
provided for in Section 2.01 hereof shall be deemed to be a grant by the Seller
and the Depositor to the Trustee of a security interest in all of the Seller's
and the Depositor's right, title and interest in and to the Mortgage Loans and
all amounts payable to the Holders of the Mortgage Loans in accordance with the
terms thereof and all proceeds of the conversion, voluntary or involuntary, of
the foregoing into cash, instruments, securities or other property, including
without limitation all amounts, other than investment earnings, from time to
time held or invested in the Collection Account and the Distribution Account,
whether in the form of cash, instruments, securities or other property; (3) the
obligations secured by such security agreement shall be deemed to be all of the
Depositor's obligations under this Agreement, including the obligation to
provide to the Certificateholders the benefits of this Agreement relating to the
Mortgage Loans and the Trust Fund; and (4) notifications to persons holding such
property, and acknowledgments, receipts or confirmations from persons holding
such property, shall be deemed notifications to, or acknowledgments, receipts or
confirmations from, financial intermediaries, bailees or agents (as applicable)
of the Trustee for the purpose of perfecting such security interest under
applicable law. Accordingly, the Depositor hereby grants to the Trustee a
security interest in the Mortgage Loans and all other property described in
clause (2) of the preceding sentence, for the purpose of securing to the



                                      177
<PAGE>

Trustee on behalf of the Certificateholders the performance by the Depositor of
the obligations described in clause (3) of the preceding sentence.
Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant
to Section 2.01 and the transfer pursuant to the Mortgage Loan Purchase
Agreement to be a true, absolute and unconditional sale of the Mortgage Loans

SECTION 12.01     Exercise of Rights of Holder of the Insured Certificates.

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

that unless a Certificate Insurer Default has occurred and is continuing, the

Holders of the Insured Certificates, including, without limitation: (i) the
right to direct foreclosures upon Mortgage Loans upon failure of the Master
Servicer to do so; (ii) the right to require the Seller to repurchase or
substitute for Mortgage Loans pursuant to Section 2.03; (iii) the right to give
notices of breach or to terminate the rights and obligations of the Master
Servicer pursuant to Section 7.01; (iv) the right to direct the actions of the

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

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

                  The Master Servicer hereby acknowledges and agrees that it
shall service and administer the related Mortgage Loans and any REO Properties,
and shall maintain the Collection Account and any REO Account, for the benefit
of the Certificateholders and for the benefit of the Certificate Insurer, and
all references in this Agreement (including, without limitation, in Section
3.01) to the benefit of or actions on behalf of the Certificateholders shall be
deemed to include the Certificate Insurer. Unless a Certificate Insurer Default
has occurred and is continuing, neither the Master Servicer nor the Depositor
shall undertake any litigation pursuant to Section 6.03 (other than litigation
to enforce their respective rights hereunder or defend themselves against claims
made against them) without the prior consent of the Certificate Insurer.

SECTION 12.04     Claims Upon the Policy; Policy Payments Account.

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

                  (b) The Trustee shall establish a segregated non-interest
bearing trust account for the benefit of Holders of the Insured Certificates and
the Certificate Insurer referred to herein as the "Policy Payments Account" over
which the Trustee shall have exclusive control and sole right of withdrawal. The
Trustee shall deposit any amount paid under the Policy in the Policy Payments
Account and distribute such amount only for purposes of payment to Holders of
Insured Certificates of the Guaranteed Distributions Shortfall or any amount in
respect of a Preference Claim (as defined in the Policy) for which a claim under
the Policy was made, and such amount may not be applied to satisfy any costs,
expenses or liabilities of the Master

Servicer, the Trustee or the Trust Fund. Amounts paid under the Policy shall be
transferred to the Distribution Account in accordance with the next succeeding
paragraph and disbursed by the Trustee to Holders of Insured Certificates in
accordance with Section 4.01(h) (or, in the case of an amount in respect of a
Preference Claim, to the related Holders of Insured Certificates as contemplated
in Section 12.04(d)). It shall not be necessary for such payments to be made by
checks or wire transfers separate from the checks or wire transfers used to pay
the other distributions to be made to such Holders pursuant to Section 4.01.
However, the amount of any payment of principal of or interest on the Insured
Certificates to be paid from funds transferred from the Policy Payments Account
shall be noted as provided in paragraph (c) below in the Certificate Register
and in the statement to be furnished to Holders of the Insured Certificates
pursuant to Section 4.02. Funds held in the Policy Payments Account shall not be
invested.

                  On any Distribution Date with respect to which a claim has
been made under the Policy, the amount of any funds received by the Trustee as a
result of any claim under the Policy, to the extent required to pay the
Guaranteed Distributions Shortfall on such Distribution Date, shall be withdrawn
from the Policy Payments Account and deposited in the Distribution Account and
applied by the Trustee, directly to the payment in full of the Guaranteed
Distributions Shortfall due on the Insured Certificates. Funds received by the
Trustee as a result of any claim under the Policy shall be deposited by the
Trustee in the Policy Payments Account and used solely for payment to the
Holders of the Insured Certificates and may not be applied to satisfy any costs,
expenses or liabilities of the Master Servicer, the Trustee or the Trust Fund.
Any funds remaining in the Policy Payments Account on the first Business Day
following a Distribution Date shall be remitted to the Certificate Insurer,
pursuant to the instructions of the Certificate Insurer, by the end of such
Business Day.

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

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

SECTION 12.05     Effect of Payments by Certificate Insurer; Subrogation.

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

                  The Trustee and the Master Servicer shall cooperate in all
respects with any reasonable request by the Certificate Insurer for action to
preserve or enforce the Certificate Insurer's rights or interests under this
Agreement without limiting the rights or affecting the interests of the Holders
as otherwise set forth herein.

SECTION 12.06     Notices to Certificate Insurer.

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

SECTION 12.07     Third Party Beneficiary.

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

SECTION 12.08     Trustee to Hold the Policy.

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

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

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

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

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

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

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

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

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

                                      A-7-3

<PAGE>
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 to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

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

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

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

from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  The Pass-Through Rate applicable to the calculation of
interest payable with respect to this Certificate on any Distribution Date shall
be the lesser of (x) the related Formula Rate for such Distribution Date and (y)
the Net WAC Pass-Through Rate for such Distribution Date. For any Distribution
Date and this Certificate, the Formula Rate is One-Month LIBOR plus the
Certificate Margin. The Certificate Margin for this Certificate is 1.150% in the
case of each Distribution Date through and including the Optional Termination
Date, or 1.725%, in the case of any Distribution Date thereafter.

                  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

                                     A-10-3



<PAGE>
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 to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

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

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

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

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

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

Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 5.02(c) of the Agreement.

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

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

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

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

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

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

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

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

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

obligations of the Depositor, the Master Servicer, the Trustee and the rights of

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.

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


                                     A-16-4
<PAGE>
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 cannot be exercised until the Optional Termination Date.

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

entitled thereto if such Person shall have so notified the Trustee in writing at
least five Business Days prior to the Record Date immediately prior to such

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

                  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.
                                     A-17-3

<PAGE>

                  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 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
                                     A-17-4

<PAGE>

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

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

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

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


                                     A-18-6


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

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

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

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

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

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

                  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


                                     A-19-5




<PAGE>
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.

                  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-X 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-X 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




                                     A-19-6

"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

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

Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right cannot be exercised until the Optional Termination Date.

                  This is a Mortgage Loan Purchase Agreement (the "Agreement"),
dated October 4, 2004, between Ameriquest Mortgage Company, a Delaware
corporation (the "Seller"), and Ameriquest Mortgage Securities Inc., a Delaware
corporation (the "Purchaser").

                              PRELIMINARY STATEMENT

                  The Seller intends to sell the Mortgage Loans (as hereinafter
defined) to the Purchaser on the terms and subject to the conditions set forth
in this Agreement. The Purchaser shall deposit the Mortgage Loans into a
mortgage pool constituting the Trust Fund. The Trust Fund will be evidenced by a
single series of asset-backed pass-through certificates designated as Series
2004-R10 (the "Certificates"). The Certificates will consist of nineteen classes
of certificates. The Class CE Certificates, the Class P Certificates and the
Residual Certificates (collectively, the "Non-Offered Certificates") will be
delivered to the Seller or its designee as partial consideration for the
Mortgage Loans as further described below.

                  The Certificates will be issued pursuant to a Pooling and
Servicing Agreement relating to the Series 2004-R10 Certificates, dated as of
October 1, 2004 (the "Pooling and Servicing Agreement"), among the Purchaser as
depositor (in such capacity, the "Depositor"), the Seller as master servicer (in
such capacity the "Master Servicer") and Deutsche Bank National Trust Company as
trustee (the "Trustee"). Pursuant to the Pooling and Servicing Agreement, the
Depositor will assign all of its right, title and interest in and to the
Mortgage Loans, together with its rights under this Agreement, to the Trustee
for the benefit of the Certificateholders. Capitalized terms used but not
defined herein shall have the meanings set forth in the Pooling and Servicing
Agreement.

                  The parties hereto agree as follows:

                  SECTION 1. AGREEMENT TO PURCHASE. The Seller hereby sells, and
the Purchaser hereby purchases, as of October 7, 2004 (the "Closing Date"),

                                    (6) 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,

                  If any document referred to in Section 4(b)(2), 4(b)(3) or
4(b)(4) 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 Seller hereunder shall be deemed to have been satisfied upon
(1) delivery by or on behalf of the Seller 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 Seller in the case of (x)
above or the public recording office in the case of (y) above to be a true and

                                       3

delivered copy is certified by the Seller, 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 Seller 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 Seller of any such original title insurance policy
the Seller shall deliver such to the Purchaser or any assignee, transferee or
designee of the Purchaser.

                  The Seller shall promptly (and in no event later than thirty
(30) Business Days, subject to extension upon mutual agreement between the

date of receipt by the Seller 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 (3) and (4) above and shall execute each original
Assignment referred to in (3) 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
Seller shall promptly prepare or cause to be prepared a substitute Assignment or
cure or cause to be cured such defect, as the case may be, and thereafter cause
each such Assignment to be duly recorded. Notwithstanding the foregoing,
however, for administrative convenience and facilitation of servicing and to
reduce closing costs, the Assignments of Mortgage shall not be required to be
submitted for recording (except with respect to any Mortgage Loan located in
Maryland) unless such failure to record would result in a withdrawal or a
downgrading by any Rating Agency of the rating on any Class of Certificates
(without regard to the Policy); provided further, however, each Assignment shall
be submitted for recording by the Seller in the manner described above, at no
expense to the Trust Fund or the Trustee, upon the earliest to occur of: (i)
reasonable direction by Holders of Certificates entitled to at least 25% of the
Voting Rights, the Certificate Insurer or the NIMS Insurer, if any, (ii) a
failure of the Master Servicer Termination Test as set forth in the Pooling and
Servicing Agreement, (iii) the occurrence of the bankruptcy or insolvency of the
Seller, (iv) the occurrence of a servicing transfer as described in Section 7.02
of the Pooling and Servicing Agreement and (v) if the Seller is not the Master
Servicer and with respect to any one assignment or Mortgage, the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Mortgagor under the
related Mortgage.

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

                           (c) ACCEPTANCE OF MORTGAGE LOANS. The documents
delivered pursuant to Section 4(b) hereof shall be reviewed by the Purchaser or
any assignee, transferee or designee of the Purchaser at any time before or
after the Closing Date (and with respect to each document permitted to be
delivered after the Closing Date, within seven (7) days of its delivery) to
ascertain that all required documents have been executed and received and that
such documents relate to the Mortgage Loans identified on the Mortgage Loan
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 Seller, and the assignee shall
succeed to the rights and obligations hereunder of the Purchaser. Any expense
reasonably incurred by or on behalf of the Purchaser, the Certificate Insurer or
the Trustee in connection with enforcing any obligations of the Seller under
this Agreement shall be promptly reimbursed by the Seller.

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

                                    (1) The information set forth on the

         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

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

                           (10) Each Mortgage Loan at origination complied in

         opportunity, real estate settlement procedures, truth-in-lending,
         disclosure laws and all applicable predatory and abusive lending laws,
         and consummation of the transactions contemplated hereby will not
         involve the violation of any such laws;

                           (11) Neither the Seller nor any prior holder of any
         Mortgage has modified, impaired or waived 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

         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;

         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 Seller 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 Seller, has done, by act or omission, anything which
         would impair the coverage of such lender's title insurance policy;

                           (13) Each Mortgage Loan was originated by the Seller,
         or an Affiliate of the Seller, in accordance with the underwriting
         standards as set forth in the Prospectus Supplement (or, if generated
         by an entity other than the Seller or an Affiliate of the Seller, in

         Prospectus Supplement or, if generated on behalf of the Seller or an
         Affiliate of the Seller by a person other than the Seller or such
         Affiliate of the Seller, is subject to the same underwriting standards
         and procedures used by the Seller in originating mortgage loans
         directly) or by a savings and loan association, savings bank,

                           (14) 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;

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

                           (16) All inspections, licenses and certificates
         required to be made or issued with respect to all occupied portions of
         the Mortgaged Property, including but not limited to certificates of
         occupancy, have been made or obtained from the appropriate authorities,
         and the Mortgaged Property is lawfully occupied under applicable law
         except as may otherwise be insured against by the lender's title
         insurance policy referred to in (12) above.

                           (17) 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;

                           (18) 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;

                           (19) 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;

                           (20) The related Mortgage contains customary and
         enforceable provisions which render the rights and remedies of the
         holder thereof adequate for the


                                       9
<PAGE>

         realization against the Mortgaged Property of the benefits of the
         security, including, (i) in the case of a Mortgage designated as a deed
         of trust, by trustee's sale, and (ii) otherwise by judicial
         foreclosure. There is no homestead or other exemption available to the
         Mortgagor which would materially interfere with the right to sell the
         Mortgaged Property at a trustee's sale or the right to foreclose the
         Mortgage;

                           (21) 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;

                           (22) 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 Seller have
         been capitalized under the Mortgage or the related Mortgage Note;

                           (23) The origination, collection and servicing
         practices used by the Seller (or its affiliate) with respect to each
         Mortgage Loan have been in all material respects legal, proper,
         reasonable and customary in the subprime mortgage origination and
         servicing business and each of the Mortgage Loans have been serviced by
         the Seller since origination;

                           (24) There is no pledged account or other security
         other than real estate securing the Mortgagor's obligations;

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

                           (26) The improvements upon each Mortgaged Property
         are covered by a valid, binding and existing hazard insurance policy
         that is in full force and effect with a generally acceptable carrier
         that provides for fire extended coverage and such other hazards as are
         customary in the area where the Mortgaged Property is located
         representing coverage not less than the lesser of the outstanding
         principal balance of the related Mortgage Loan or the minimum amount
         required to compensate for damage or loss on a replacement cost basis.
         All individual insurance policies and flood policies referred to in
         clause (27) below contain a standard mortgagee clause naming the Seller
         or the original mortgagee, and its successors in interest, as
         mortgagee, and the Seller 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;

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

                           (28) There is no default, breach, violation or event

         Note; and the Seller has not waived any default, breach, violation or
         event of acceleration;

                           (29) Each Mortgaged Property is improved by a one- to

         dwelling units in planned unit developments, which does not include (a)
         cooperatives or (b) mobile homes and manufactured homes (as defined in
         the Fannie Mae Seller-Servicer's Guide), except when the appraisal
         indicates that (i) the mobile or manufactured home was built under the
         Federal Manufactured Home Construction and Safety Standards of 1976 or
         (ii) otherwise assumes the characteristics of site-built housing and
         meets local building codes, is readily marketable, has been permanently
         affixed to the site, is not in a mobile home "park," and is treated as
         real property under the applicable state law. With respect to any

         valid, in full force and effect; (b) all rents and other payments due
         under the lease have been paid; (c) the lessee is not in default under
         any provision of the lease; (d) the term of the lease exceeds the

         and (e) the Mortgagee under the Mortgage Loan is given notice and an
         opportunity to cure any defaults under the lease;

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

         consolidated, bears a single interest rate and single repayment term
         reflected on the Mortgage Loan Schedule. The consolidated principal

         for the acceleration of the payment of the unpaid principal balance of
         the Mortgage Loan in the event that the related Mortgaged Property is
         sold or transferred without the prior written consent of the mortgagee
         thereunder, except as may be limited by applicable law;

                           (37) The information set forth in the Prepayment
         Charge Schedule attached as Schedule 2 to the Pooling and Servicing

                           (43) The Master Servicer for each Mortgage Loan prior
         to the Closing Date, has fully furnished, in accordance with the Fair

         transaction.

                  (b) The Seller hereby represents and warrants to the
Purchaser, with respect to the Group I Mortgage Loans as of the Closing Date or
as of such date specifically provided herein:

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

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



                                       13
<PAGE>

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

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

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

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

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

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

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

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

                  Upon discovery by the Seller, the Purchaser or any assignee,
transferee or designee of the Purchaser of any materially defective document in,
or that any material document was not transferred by the Seller (as listed on
the Trustee's Preliminary Exception Report) as part of, any Mortgage File or of
a breach of any of the representations and warranties contained in Section 5 or
Section 6 that materially and adversely affects the value of any Mortgage Loan
or the interest therein of the Purchaser or the Purchaser's assignee, transferee
or designee (it being understood that with respect to the representations and
warranties set forth in (39), (40), (41), (42), (43), (44), (46) and (48) of
Section 6(a) herein, a breach of any such representation or warranty shall in
and of itself be deemed to materially adversely affect the interest therein of
the Purchaser and the Purchaser's assignee, transferee or designee), the party
discovering the breach shall give prompt written notice to the others. Within
ninety (90) days of its discovery or its receipt of notice of any such missing
documentation which was not transferred to the Purchaser as described above or
materially defective documentation or any such breach of a representation and
warranty (it being understood that with respect to the representations and
warranties set forth in (39), (40), (41), (42), (43), (44), (46) and (48) of
Section 6(a) herein, a breach of any such


                                       15
<PAGE>

representation or warranty shall in and of itself be deemed to materially
adversely affect the interest therein of the Purchaser and the Purchaser's
assignee, transferee or designee), the Seller promptly shall deliver such
missing document or cure such defect or breach in all material respects, or in
the event the Seller cannot deliver such missing document or such defect or
breach cannot be cured, the Seller shall, within ninety (90) days of its
discovery or receipt of notice, either (i) repurchase the affected Mortgage Loan
at a price equal to the Purchase Price or (ii) pursuant to the provisions of the
Pooling and Servicing Agreement, cause the removal of such Mortgage Loan from
the Trust Fund and substitute one or more Qualified Substitute Mortgage Loans.
In the event that any Mortgage Loan is subject to a breach of the representation
and warranty in Section 6(a)(37) and (45) resulting in the Master Servicer's
inability to collect all or part of the Prepayment Charge from the Mortgagor, in
lieu of repurchase, the Seller shall be obligated to remit to the Master
Servicer (for deposit in the Collection Account) any shortfall in the Prepayment
Charge collected upon the Mortgagor's voluntary Principal Prepayment.

                  Notwithstanding the foregoing, within ninety (90) days of the
earlier of discovery by the Seller or receipt of notice by the Seller of the
breach of the representation of the Seller set forth in Section 6(a)(37) and
(45) above, which materially and adversely affects the interests of the Holders
of the Class P Certificates in any Prepayment Charge, the Seller shall pay the
amount of the scheduled Prepayment Charge, for the benefit of the Holders of the
Class P Certificates, by depositing such amount into the Collection Account, net
of any amount previously collected by the Master Servicer and paid by the Master
Servicer, for the benefit of the Holders of the Class P Certificates, in respect
of such Prepayment Charge.

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

                  In addition, upon discovery by the Seller, the Purchaser, or
any assignee, transferee or designee of the Purchaser that any Mortgage Loan
does not constitute a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code, the party discovering the breach shall give prompt
written notice within five (5) Business Days to the others. Within ninety (90)
days of its discovery or its receipt of notice, the Seller promptly shall either
(i) repurchase the affected Mortgage Loan at the Purchase Price (as such term is
defined in the Pooling and Servicing Agreement) or (ii) pursuant to the
provisions of the Pooling and Servicing Agreement, cause the removal of such
Mortgage Loan from the Trust Fund and substitute one or more Qualified
Substitute Mortgage Loans.

                           (b) It is understood and agreed that the obligations
of the Seller set forth in this Section 7 to cure, remit a Prepayment Charge
shortfall, repurchase or substitute for a defective Mortgage Loan constitute the
sole remedies of the Purchaser against the Seller


                                       16
<PAGE>

respecting a missing or defective material document or a breach of the
representations and warranties contained in Section 5 or Section 6.

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

                  (a)      All of the representations and warranties of the
                           Seller under this Agreement shall be true and correct
                           in all material respects as of the date as of which
                           they are made and no event shall have occurred which,
                           with notice or the passage of time, would constitute
                           a default under this Agreement;

                  (b)      The Purchaser shall have received, or the attorneys
                           of the Purchaser shall have received in escrow (to be

                           Agreement, in such forms as are agreed upon and
                           acceptable to the Purchaser, duly executed by all
                           signatories other than the Purchaser as required
                           pursuant to the respective terms thereof;

                  (c)      The Seller shall have delivered or caused to be
                           delivered and released to the Purchaser or to its
                           designee, all documents (including without
                           limitation, the Mortgage Loans) required to be so
                           delivered by the Purchaser pursuant to Section 2.01
                           of the Pooling and Servicing Agreement; and

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

                  Subject to the foregoing conditions, the Purchaser shall

of Section 8 hereof, the closing shall be subject to delivery of each of the
following documents:

                  (a)      (i) An Officers' Certificate of the Seller and Master
                           Servicer, dated the Closing Date, in form

                           incorporation, by-laws and certificate of good

                  SECTION 12. RESERVED.

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

         Notwithstanding the foregoing, if on the Closing Date, each of the
conditions set forth in Section 8 hereof shall have been satisfied and the
Purchaser shall not have paid or caused to be


                                       19
<PAGE>

paid the Purchase Price, or any such condition shall not have been waived or
satisfied and the Purchaser determines not to pay or cause to be paid the
Purchase Price, the Purchaser shall immediately effect the redelivery of the
Mortgage Loans, if delivery to the Purchaser has occurred and the security
interest created by this Section 13 shall be deemed to have been released.

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

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

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

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

                  SECTION 18. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS,
DUTIES, OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES HERETO SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS (EXCLUDING THE CHOICE OF LAW
PROVISIONS) AND DECISIONS


                                       20

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

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

         Act.

                  2. The Transferee has been furnished with all information

amended.

                  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.

Transferee agrees that, in connection with any purchase of securities sold to
the Transferee for the account of a third


                                  F-Annex-1-5
<PAGE>

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.

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

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

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

                  1. I am a ______________________ of
____________________________ (the "Owner") a corporation duly organized and
existing under the laws of ______________, the record owner of Ameriquest
Mortgage Securities Inc., Asset-Backed Pass-Through Certificates, Series
2004-R10, Class R (the "Residual 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 Residual Certificates were issued.

                  2. The Owner (i) is and will be a "Permitted Transferee" as of
____________________, 2004 and (ii) is acquiring the Residual 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 Residual Certificates to disqualified organizations under the
Internal Revenue Code of 1986, as amended, that applies to all transfers of the
Residual 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 Residual 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 Residual 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 Residual 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 Residual Certificates and the provisions of Section 5.02(d) of the
Pooling and Servicing Agreement under which the Residual 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
Residual 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 Residual Certificates, have sufficient assets to pay any taxes owed by the
holder of such Residual Certificates, and hereby represents to and for the
benefit of the person from whom it acquired the Residual Certificates that the
Owner intends to pay taxes associated with holding such Residual Certificates as
they become due, fully understanding that it may incur tax liabilities in excess
of any cash flows generated by the Residual 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
Residual 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 Residual Certificates with
the intent to transfer the Residual Certificates to any person or entity that
will not have sufficient assets to pay any taxes owed by the holder of such
Residual Certificates, or that may become insolvent or subject to a bankruptcy
proceeding, for so long as the Residual Certificates remain outstanding.

<PAGE>

                  14. The Owner will, in connection with any transfer that it
makes of the Residual 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 Residual Certificates, deliver to the Certificate Registrar an
affidavit, which represents and warrants that it is not transferring the
Residual 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 Residual
Certificates; (ii) may become insolvent or subject to a bankruptcy proceeding
for so long as the Residual 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.

                  1. I am a ____________________ of (the "Owner"), a corporation
duly organized and existing under the laws of ______________, on behalf of whom
I make this affidavit.

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

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

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

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

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

</TABLE>

         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.
