          This Pooling and Servicing Agreement is dated as of June 1, 2004
(the "Agreement"), among J.P. MORGAN ACCEPTANCE CORPORATION I, as depositor
(the "Depositor"), CREDIT-BASED ASSET SERVICING AND SECURITIZATION LLC, as
seller (the "Seller"), LITTON LOAN SERVICING LP, as servicer (the "Servicer")
and U.S. BANK NATIONAL ASSOCIATION, as trustee (the "Trustee").

                             PRELIMINARY STATEMENT

          The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple
Classes, which in the aggregate will evidence the entire beneficial ownership
interest in the Trust Fund created hereunder. The Certificates will consist of
seventeen Classes of Certificates, designated as (i) the Class A-1
Certificates, the Class A-2 Certificates, the Class A-3 Certificates, the
Class A-4 Certificates, the Class A-5 Certificates and the Class A-6
Certificates, (ii) the Class M-1 Certificates, Class M-2 Certificates and the
Class M-3 Certificates, (iii) the Class B-1 Certificates, the Class B-2
Certificates, the Class B-3 Certificates and the Class B-4 Certificates, (iv)
the Class N Certificates, (v) the Class X Certificates and (vi) the Class R
Certificates and the Class R-X Certificates. Each REMIC regular interest
created hereby will be retired on or before May 25, 2035 (the "Assumed Final
Rate Maturity Date").

                                    REMIC 1
                                    -------

          As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (but exclusive of the LIBOR Carryover
Reserve Account) as a real estate mortgage investment conduit (a "REMIC") for
federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC 1." The Class R-1 Interest will represent the sole class
of "residual interests" in REMIC 1 for purposes of the REMIC Provisions under
federal income tax law. The REMIC 1 Regular Interests will have the Initial
Principal Amounts, Pass-Through Rates and Corresponding Certificates as set
forth in the following table:

                         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, on
behalf of the Trust, without recourse for the benefit of the
Certificateholders all the right, title and interest of the Depositor,
including any security interest therein for the benefit of the Depositor, in
and to (i) each Mortgage Loan identified on the Mortgage Loan Schedule,
including the related Cut-off Date Principal Balance, all interest accruing
thereon after the Cut-off Date and all collections in respect of interest and
principal due after the Cut-off Date; (ii) property which secured each such
Mortgage Loan and which has been acquired by foreclosure or deed in lieu of
foreclosure; (iii) its interest in any insurance policies in respect of the
Mortgage Loans; (iv) all proceeds of any of the foregoing; (v) the rights of
the Depositor under the Mortgage Loan Purchase Agreement and (vi) all other
assets included or to be included in the Trust Fund; PROVIDED, HOWEVER, so
long as the Servicer is an FHA Approved Mortgagee, the Commissioner of HUD
shall have no obligation to recognize or deal with any person other than the
Servicer with respect to FHA Insurance. Such assignment includes all interest
and principal due to the Depositor or the Servicer after the Cut off Date with
respect to the Mortgage Loans.

          In connection with such transfer and assignment, the Seller, on
behalf of the Depositor, does hereby deliver or cause to be delivered to, and

          recourse," or with respect to any lost Mortgage Note, an original
          Lost Note Affidavit, together with a copy of the related Mortgage
          Note;

     (ii) the original Mortgage with evidence of recording thereon, and the
          original recorded power of attorney, if the Mortgage was executed
          pursuant to a power of attorney, with evidence of recording thereon
          or, if such Mortgage or power of attorney has been submitted for
          recording but has not been returned from the applicable public
          recording office, has been lost or is not otherwise available, a
          copy of such Mortgage or power of attorney, as the case may be,
          certified to be a true and complete copy of the original submitted
          for recording;

    (iii) an original Assignment of Mortgage, in form and substance

          Bank National Association, as Trustee under the Pooling and Servicing
          Agreement, dated as of June 1, 2004, among Credit-Based Asset
          Servicing and Securitization LLC, J.P. Morgan Acceptance Corporation
          I, Litton Loan Servicing LP and U.S. Bank National Association,
          C-BASS Mortgage Loan Asset-Backed Certificates, Series 2004-CB4,
          without recourse";

     (iv) an original or a certified copy of any intervening assignment of
          Mortgage showing a complete chain of assignments;

     (v)  the original or a certified copy of lender's title insurance policy;

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

    (vii) for each FHA Loan, the original Mortgage Insurance Certificate.

          If any of the documents referred to in Section 2.01(ii), (iii) or
(iv) above has as of the Closing Date been submitted for recording but either
(x) has not been returned from the applicable public recording office or (y)
has been lost or such public recording office has retained the original of
such document, the obligations of the Seller to deliver such documents shall
be deemed to be satisfied upon (1) delivery to the Trustee or the Custodian no
later than the Closing Date, of a copy of each such document certified by the
Seller 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 Seller,
delivery to the Trustee or the Custodian, 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. The
Seller shall deliver or cause to be delivered to the Trustee or the Custodian
promptly upon receipt thereof any other 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.

          Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Seller
shall have 120 days to cure such defect or 150 days following the Closing
Date, in the case of missing Mortgages or Assignments or deliver such missing
document to the Trustee or the Custodian. If the Seller does not cure such
defect or deliver such missing document within such time period, the Seller
shall either repurchase or substitute for such Mortgage Loan in accordance
with Section 2.03.

          The Servicer shall cause the Assignments of Mortgage which were
delivered in blank to be completed and shall cause all Assignments referred to
in Section 2.01(iii) hereof and, to the extent necessary, in Section 2.01(iv)
hereof to be recorded. The Servicer shall be required to deliver such
assignments for recording within 30 days of the Closing Date. The Servicer
shall furnish the Trustee, or its designated agent, with a copy of each
Assignment of Mortgage submitted for recording. In the event that any such
Assignment is lost or returned unrecorded because of a defect therein, the
Servicer shall promptly have a substitute Assignment prepared or have such
defect cured, as the case may be, and thereafter cause each such Assignment to
be duly recorded.

                                      47
<PAGE>

          In the event that any Assignments of Mortgage are not recorded or
are improperly recorded, the Servicer shall have no liability for its failure
to receive or act on notices not received related to such Assignment of
Mortgage.

          In the event that any Mortgage Note is endorsed in blank as of the
Closing Date, promptly following the Closing Date the Servicer shall cause to
be completed such endorsements in the following form: "Pay to the order of
U.S. Bank National Association, as Trustee under the Pooling and Servicing
Agreement, dated as of June 1, 2004, among Credit-Based Asset Servicing and
Securitization LLC, J.P. Morgan Acceptance Corporation I, Litton Loan
Servicing LP and U.S. Bank National Association, C-BASS Mortgage Loan
Asset-Backed Certificates, Series 2004-CB4, without recourse."

          The Depositor herewith delivers to the Trustee executed copies of
the Mortgage Loan Purchase Agreement.

          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 the Homeownership and Equity Protection Act of 1994 or any other
applicable predatory or abusive lending laws.

          Section 2.02 Acceptance by the Trustee.

          The Trustee acknowledges the receipt of, subject to the provisions
of Section 2.01 and subject to the review described below and any exceptions
noted on the exception report described in the next paragraph below, the
documents referred to in Section 2.01 above and all other assets included in
the definition of "Trust Fund" and declares that it holds and will hold such
documents and the other documents delivered to it constituting a Mortgage
File, and that it holds or will hold all such assets and such other assets
included in the definition of "Trust Fund" in trust for the exclusive use and
benefit of all present and future Certificateholders.

          The Trustee agrees to execute and deliver (or cause the Custodian to
execute and deliver) to the Depositor on or prior to the Closing Date an
acknowledgment of receipt of the original Mortgage Note (with any exceptions
noted), substantially in the form attached as Exhibit F-3 hereto.

          The Trustee agrees, for the benefit of the Certificateholders, to
review (or cause the Custodian to review) each Mortgage File within 60 days
after the Closing Date (or, with respect to any document delivered after the
Startup Day, within 60 days of receipt and with respect to any Qualified
Substitute Mortgage, within 60 days after the assignment thereof) and to
certify (or cause the Custodian to certify) in substantially the form attached
hereto as Exhibit F-1 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 required to be delivered to
it pursuant to Section 2.01 of this Agreement are in its possession, (ii) such
documents have been reviewed by it and have not been mutilated, damaged or
torn and relate to such Mortgage Loan, (iii) based on its examination and only
as to the foregoing, the information set forth in the Mortgage Loan Schedule
that corresponds to items (1), (2), (3), (5) (13) and (26) (but only as to

                                      48
<PAGE>

whether the Mortgage Loan as a Prepayment Charge) of the Mortgage Loan
Schedule accurately reflects information set forth in the Mortgage File, (iv)
all Assignments of Mortgage or intervening assignments of mortgage, as
applicable, have been submitted for recording and (v) each Mortgage Note has
been endorsed as provided in Section 2.01(i) of this Agreement and each
Mortgage has been assigned in accordance with Section 2.01(iii) of this
Agreement. It is herein acknowledged that, in conducting such review, the
Trustee (or the Custodian, as applicable) is under no duty or obligation to
inspect, review or examine any such documents, instruments, certificates or
other papers to determine that they are genuine, enforceable, or appropriate
for the represented purpose or that they have actually been recorded or that
they are other than what they purport to be on their face.

          Prior to the first anniversary date of this Agreement the Trustee
shall deliver (or cause the Custodian to deliver) to the Depositor and the
Servicer a final certification in the form annexed hereto as Exhibit F-2
evidencing the completeness of the Mortgage Files, with any applicable
exceptions noted thereon.

          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 the Custodian, as applicable) finds any document or documents
constituting a part of a Mortgage File to be missing or defective in any
material respect, at the conclusion of its review the Trustee, upon its
notification by the Custodian, if applicable, shall so notify the Seller, the
Depositor and the Servicer. In addition, upon the discovery by the Seller,
Depositor, the Trustee or the Servicer (or upon receipt by the Trustee of
written notification of such breach) of a breach of any of the representations
and warranties made by the Seller in the related Mortgage Loan Purchase
Agreement in respect of any Mortgage Loan which materially adversely affects
such Mortgage Loan or the interests of the related Certificateholders in such
Mortgage Loan, the party discovering such breach shall give prompt written
notice to the other parties.

          The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans and the
Related Documents, conveying good title thereto free and clear of any liens
and encumbrances, from the Depositor to the Trustee and that such property not
be part of the Depositor's estate or property of the Depositor in the event of
any insolvency by the Depositor. In the event that such conveyance is deemed
to be, or to be made as security for, a loan, the parties intend that the
Depositor shall be deemed to have granted and does hereby grant to the
Trustee, on behalf of the Trust, a first priority perfected security interest
in all of the Depositor's right, title and interest in and to the Mortgage
Loans and the Related Documents, and that this Agreement shall constitute a
security agreement under applicable law.

          Section 2.03 Repurchase or Substitution of Mortgage Loans by the
                       Seller.

          (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, a Mortgage File or
of the breach by the Seller of any representation, warranty or covenant under
the Mortgage Loan Purchase Agreement or in Section 2.04 in respect of any
Mortgage Loan which materially adversely affects the value of such Mortgage
Loan or the interest therein of the Certificateholders, the Trustee (or the
Custodian, as applicable) shall promptly notify the Seller and the Servicer of
such defect,

                                      49
<PAGE>

missing document or breach and request that the Seller deliver such
missing document or cure such defect or breach within 120 days or 150 days
following the Closing Date, in the case of missing Mortgages or Assignments
from the date the Seller 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 Trustee
shall enforce the Seller's obligation under the Mortgage Loan Purchase
Agreement and inform the Seller of its obligation to repurchase such Mortgage
Loan from the Trust Fund at the Purchase Price on or prior to the
Determination Date following the expiration of such 120 day period (subject to
Section 2.03(e)); provided that, in connection with any such breach that could
not reasonably have been cured within such 120 day or 150 day period, if the
Seller shall have commenced to cure such breach within such 120 day or 150 day
period, the Seller shall be permitted to proceed thereafter diligently and
expeditiously to cure the same within the additional period provided 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 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,
representation or warranty, 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 have no further responsibility with regard to such Mortgage
File. In lieu of repurchasing any such Mortgage Loan as provided above, the
Seller may cause such Mortgage Loan to be removed from the Trust Fund (in
which case it shall become a Defective Mortgage Loan) and substitute one or
more Eligible Substitute Mortgage Loans in the manner and subject to the
limitations set forth in Section 2.03(d). It is understood and agreed that the
obligation of the Seller to cure or to repurchase (or to substitute for) any
Mortgage Loan as to which a document is missing, a material defect in a
constituent document exists or as to which such a breach has occurred and is
continuing shall constitute the sole remedy against the Seller respecting such
omission, defect or breach available to the Trustee on behalf of the
Certificateholders.

          (b) [Reserved].

          (c) Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of any representation,
warranty or covenant of the Servicer set forth in Section 2.05 which
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, the Servicer shall cure such breach in all material
respects.

          (d) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected
prior to the last Business Day that is within two years after the Closing
Date. As to any Defective Mortgage Loan for which the Seller substitutes an
Eligible Substitute Mortgage Loan or Loans, such substitution shall be
effected by the Seller delivering to the Trustee, for such Eligible 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 Eligible Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution
Adjustment Amount (as described below), if any, in connection with such
substitution. The Trustee shall acknowledge receipt for such Eligible
Substitute Mortgage Loan or Loans and, within ten Business Days

                                      50
<PAGE>

thereafter, shall review such documents as specified in Section 2.02 and
deliver (or cause the Custodian to deliver) to the Servicer, with respect
to such Eligible Substitute Mortgage Loan or Loans, a certification
substantially in the form attached hereto as Exhibit F-1, with any applicable
exceptions noted thereon. Within one year of the date of substitution, the
Trustee shall deliver (or cause the Custodian to deliver) to the Servicer a
certification substantially in the form of Exhibit F-2 hereto with respect to
such Eligible Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Eligible
Substitute Mortgage Loans in the month of substitution are not part of the
Trust Fund and will be retained by the Seller. For the month of substitution,
distributions to Certificateholders will reflect the collections and
recoveries in respect of such Defective Mortgage Loan in the Collection Period
preceding 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 Defective Mortgage Loan. The Seller shall give or
cause to be given written notice to the Certificateholders that such
substitution has taken place, shall amend the Mortgage Loan Schedule to
reflect the removal of such Defective Mortgage Loan from the terms of this
Agreement and the substitution of the Eligible Substitute Mortgage Loan or
Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the
Trustee and the Custodian. Upon such substitution, such Eligible Substitute
Mortgage Loan or Loans shall constitute part of the Mortgage Pool and shall be
subject in all respects to the terms of this Agreement and, in the case of a
substitution effected by the Seller, the Mortgage Loan Purchase Agreement,
including, in the case of a substitution effected by the Seller all applicable
representations and warranties thereof included in the Mortgage Loan Purchase
Agreement and all applicable representations and warranties thereof set forth
in Section 2.04, in each case as of the date of substitution.

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

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

                                      51
<PAGE>

          (e) Upon discovery by the Seller, the 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 shall repurchase or, subject to
the limitations set forth in Section 2.03(d), substitute one or more Eligible
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. In addition, upon discovery that a Mortgage Loan is defective
in a manner that would cause it to be a "defective obligation" within the
meaning of Treasury regulations relating to REMICs, the Seller shall cure the
defect or make the required purchase or substitution no later than 90 days
after the discovery of the defect. Any such repurchase or substitution shall
be made in the same manner as set forth in Section 2.03(a), if made by the
Seller. The Trustee shall reconvey to the Seller the Mortgage Loan to be
released pursuant hereto in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

          Notwithstanding anything to the contrary contained herein, the
parties hereto acknowledge that the functions of the Trustee with respect to
the custody, acceptance, inspection and release of the Mortgage Files pursuant
to Sections 2.01, 2.02 and 2.03 and preparation and delivery of the
certifications in the form of Exhibit F-1, Exhibit F-2 and Exhibit F-3 shall
be performed by the Custodian pursuant to the terms and conditions of the
Custodial Agreement. The fees and expenses of the Custodian shall be paid by
the Servicer.

          Section 2.04 Representations and Warranties of the Seller with
                       Respect to the Mortgage Loans.

                     The Seller hereby represents and warrants to the Trustee
for the benefit of the Certificateholders and the
Depositor that as of the Closing Date or as of such other date specifically
provided herein:

          (a) The representations and warranties made by the Seller pursuant
to Section 3.01 of the Mortgage Loan Purchase Agreement are hereby being made
to the Trustee and are true and correct as of the Closing Date.

          (b) Any written agreement between the Mortgagor in respect of a
Mortgage Loan and the Servicer modifying such Mortgagor's obligation to make
payments under the Mortgage Loan (such modified Mortgage Loan, a "Modified
Mortgage Loan") involved the application of the Seller's underwriting
standards or some assessment of the Mortgagor's ability to repay the Modified
Mortgage Loan.

          With respect to the representations and warranties set forth in this
Section 2.04 that are made to the best of the Seller's knowledge or as to
which the Seller has no knowledge, if it is discovered by the Depositor, the
Seller, the Servicer, the Trustee or the Custodian that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan or the interest
therein of the Certificateholders then, notwithstanding the Seller's lack of
knowledge with respect to the substance of such representation and warranty
being inaccurate at the time the representation or

                                      52
<PAGE>

warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

          Upon discovery by the Depositor, the Seller, the Servicer, the
Trustee or the Custodian of a breach of any of the representations and
warranties contained in this Section that materially and adversely affects the
value of any Mortgage Loan or the interest therein of the Certificateholders,
the party discovering the breach shall give prompt written notice to the
others and in no event later than two Business Days from the date of such
discovery. Within ninety days of its discovery or its receipt of notice of any
such missing or materially defective documentation or any such breach of a
representation or warranty, the Seller shall promptly deliver such missing
document or cure such defect or breach in all material respects, or in the
event such defect or breach cannot be cured, the Seller shall repurchase the
affected Mortgage Loan or cause the removal of such Mortgage Loan from the
Trust Fund and substitute for it one or more Eligible Substitute Mortgage
Loans, in either case, in accordance with Section 2.03.

          It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the Mortgage Files to
the Trustee and shall inure to the benefit of the Certificateholders and the
Depositor notwithstanding any restrictive or qualified endorsement or
assignment. It is understood and agreed that the obligations of the Seller set
forth in Section 2.03(a) to cure, substitute for or repurchase a Mortgage Loan
pursuant to the Mortgage Loan Purchase Agreement constitute the sole remedies
available to the Depositor and to the Certificateholders or to the Trustee on
their behalf respecting a breach of the representations and warranties
contained in this Section 2.04.

          Section 2.05 Representations, Warranties and Covenants of the
                       Servicer.

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

          (i) The Servicer is duly organized, validly existing, and in good
     standing under the laws of the jurisdiction of its formation and has all
     licenses necessary to carry on its business as now being conducted,
     except for such licenses, certificates and permits the absence of which,
     individually or in the aggregate, would not have a material adverse
     effect on the ability of the Servicer to conduct its business as it is
     presently conducted, and is licensed, qualified and in good standing in
     the states where the Mortgaged Property is located if the laws of such
     state require licensing or qualification in order to conduct business of
     the type conducted by the Servicer or to ensure the enforceability or
     validity of each Mortgage Loan; the Servicer has the power and authority
     to execute and deliver this Agreement and to perform in accordance
     herewith; the execution, delivery and performance of this Agreement
     (including all instruments of transfer to be delivered pursuant to this
     Agreement) by the Servicer and the consummation of the transactions
     contemplated hereby have been duly and validly authorized; this Agreement
     evidences the valid, binding and enforceable obligation of the Servicer,
     subject to applicable bankruptcy, insolvency, reorganization, moratorium
     or other similar laws affecting the enforcement of creditors' rights
     generally; and all requisite corporate action has been

                                      53
<PAGE>

     taken by the Servicer to make this Agreement valid and binding upon the
     Servicer in accordance with its terms;

          (ii) The consummation of the transactions contemplated by this
     Agreement are in the ordinary course of business of the Servicer and will
     not result in the breach of any term or provision of the certificate of
     formation or the partnership agreement of the Servicer or result in the
     breach of any term or provision of, or conflict with or constitute a
     default under or result in the acceleration of any obligation under, any
     agreement, indenture or loan or credit agreement or other instrument to
     which the Servicer or its property is subject, or result in the violation
     of any law, rule, regulation, order, judgment or decree to which the
     Servicer or its property is subject;

          (iii) The Servicer is an approved seller/servicer of conventional
     mortgage loans for Fannie Mae, and is an FHA Approved Mortgagee in good
     standing to service mortgages and has not been suspended as a mortgagee
     or servicer by the FHA and has the facilities, procedures and experienced
     personnel necessary for the sound servicing of mortgage loans of the same
     type as the Mortgage Loans. The Servicer is, and shall remain for as long
     as it is servicing the Mortgage Loans hereunder, in good standing as a
     FHA Approved Mortgagee and to service mortgage loans for HUD, Fannie Mae
     or Freddie Mac, and no event has occurred, including but not limited to a
     change in insurance coverage, which would make the Servicer unable to
     comply with HUD, Fannie Mae, Freddie Mac or FHA eligibility requirements
     or which would require notification to any of HUD, Fannie Mae, Freddie

     duly qualified to do business and is in good standing in each

     bankruptcy, insolvency, reorganization, receivership, moratorium or
     similar laws affecting the enforcement of creditors' rights generally and
     by the availability of equitable remedies, (2) general equity principles
     (regardless of whether such enforcement is considered in a proceeding in
     equity or at law) or (3) public policy considerations underlying the
     securities laws, to the extent that such policy considerations limit the
     enforceability of the provisions of this Agreement which purport to
     provide indemnification from securities laws liabilities.

          (iii) The Seller holds all necessary licenses, certificates and
     permits from all governmental authorities necessary for conducting its
     business as it is presently conducted, except for such licenses,

     Seller to conduct its business as it is presently conducted. It is not
     required to obtain the consent of any other party or any consent,
     license, approval or authorization from, or registration or declaration

     a default under, any provision

                                      57

     encumbrance upon any of its properties pursuant to any mortgage,
     indenture, contract or other agreement to which it is a party or by which
     it may be bound.

          (v) No certificate of an officer, written statement or report
     delivered pursuant to the terms hereof by the Seller contains any untrue
     statement of a material fact or omits to state any material fact

     the Seller aware of any pending insolvency.

        (viii) The Seller is not in violation of, and the execution and
     delivery of this Agreement by it and its performance and compliance with
     the terms of this Agreement will not constitute a violation with respect
     to any order or decree of any court, or any order or regulation of any
     federal, state, municipal or governmental agency having jurisdiction,
     which violation would materially and adversely affect the Seller's
     condition (financial or otherwise) or operations or any of the Seller's
     properties, or materially and adversely affect the performance of any of
     its duties hereunder.

          (ix) There are no actions or proceedings against, or investigations
     of, the Seller pending or, to its knowledge, threatened, before any
     court, administrative agency or other tribunal (i) that, if determined
     adversely, would prohibit the Seller from entering into this Agreement,
     (ii) seeking to prevent the consummation of any of the transactions
     contemplated by this Agreement or (iii) that, if determined adversely,
     would prohibit or materially and adversely affect the Seller's
     performance of any of its respective obligations under, or the validity
     or enforceability of, this Agreement.

or suffer to exist any lien on any Mortgage Loan, or any interest therein; the
Seller will notify the Trustee, as assignee of the Depositor, of the existence
of any lien on any Mortgage Loan immediately upon discovery thereof, and the
Seller will defend the right, title and interest of the Trust, as assignee of
the Depositor, in, to and under the Mortgage Loans, against all claims of
third parties claiming through or under the Seller; PROVIDED, HOWEVER, that
nothing in this Section 2.08 shall prevent or be deemed to prohibit the Seller
from suffering to exist upon any of the Mortgage Loans any liens for municipal
or other local taxes and other governmental charges if such taxes or
governmental charges shall not at the time be due and payable or if the Seller
shall currently be contesting the validity thereof in good faith by
appropriate proceedings and shall have set aside on its books adequate
reserves with respect thereto.

          (b) The Seller hereby covenants that neither it nor any Affiliate of
the Seller will directly solicit any Mortgagor hereunder to refinance the
related Mortgage Loan. For the purposes of the foregoing, neither the Seller
nor any Affiliate of the Seller shall be deemed to directly solicit any
Mortgagor if the Seller responds to a request from a Mortgagor regarding a
refinancing or if the Mortgagor receives marketing materials which are
generally disseminated.

                                 ARTICLE III

                ADMINISTRATION AND SERVICING OF THE TRUST FUND

          Section 3.01 Servicer to Act as Servicer.

          The Servicer, as independent contract servicer, shall service and
administer the Mortgage Loans in accordance with this Agreement and the normal
and usual standards of practice of prudent mortgage servicers, and shall have
full power and authority, acting alone, to do or cause to be done any and all
things in connection with such servicing and administration which the Servicer
may deem necessary or desirable and consistent with the terms of this
Agreement including, in the case of FHA Loans, taking all actions that a
mortgagee is permitted or required to take by the FHA (the "Servicing
Standards").

          Consistent with the terms of this Agreement, the 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 in the Servicer's reasonable and prudent determination such
waiver, modification, postponement or indulgence is not materially adverse to
the Certificateholders; PROVIDED, HOWEVER, that the Servicer shall not make
future advances and (unless the Mortgagor is in default with respect to the
Mortgage Loan or such default is, in the judgment of the Servicer, reasonably
foreseeable) the Servicer shall not permit any modification with respect to
any Mortgage Loan that would (i) change the Mortgage Interest Rate, defer or
forgive the payment thereof of any principal or interest payments, reduce the
outstanding principal amount (except for actual payments of principal) or
extend the final maturity date with respect to such Mortgage Loan, (ii) in the
case of FHA Loans, affect the FHA Insurance Contract with respect to such
Mortgage Loan, (iii) affect adversely the status of any REMIC as a REMIC or
(iv) cause any REMIC to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions. Notwithstanding the
foregoing, the Servicer shall not permit any modification with respect to any
Mortgage Loan that would both (x) effect an exchange or reissuance of such
Mortgage Loan under Section 1.860G-2(b) of the Treasury Regulations and (y)
cause any 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. Without
limiting the generality of the foregoing, the Servicer shall continue, and is
hereby authorized and empowered to execute and deliver on behalf of itself,
and the Trustee, all instruments of satisfaction or cancellation, or of
partial or full release, discharge and all other comparable instruments, with
respect to the Mortgage Loans and with respect to the Mortgaged Property. The
Servicer shall make all required Servicing Advances and shall service and
administer the Mortgage Loans in accordance with Applicable Regulations, and
shall provide to the Mortgagor any reports required to be provided to them
thereby. If reasonably required by the Servicer, the Trustee shall furnish the
Servicer with a power of attorney substantially in the form of Exhibit P
hereto and other documents necessary or appropriate to enable the Servicer to
carry out its servicing and administrative duties under this Agreement and the
Trustee shall have no liability with respect to any misuse of such power of
attorney and shall be indemnified by the

                                      62
<PAGE>

Servicer for any costs, liabilities or expenses incurred by the Trustee in
connection therewith. The Trustee agrees to provide such power of attorney
within ten (10) days of the Servicer's request therefor.

          Notwithstanding anything in this Agreement to the contrary, the
Servicer shall be prohibited from foreclosing on any Mortgage Loan based on
the delinquency status thereof as of the Cut-off Date.

          In servicing and administering FHA Loans, the Servicer shall comply
strictly with the National Housing Act and the FHA Regulations, and
administrative guidelines issued thereunder or pursuant thereto (insofar as
the same apply to any Mortgage Loan) and, to the extent permitted hereunder,
promptly discharge all of the obligations of the mortgagee thereunder and
under each Mortgage including the timely giving of notices, the essence hereof
being that the full benefits of each FHA Insurance Contract inure to the
Trustee, on behalf of the Certificateholders.

          In servicing and administering the Mortgage Loans, the Servicer
shall employ procedures including collection procedures and exercise the same
care that it customarily employs and exercises in servicing and administering
mortgage loans for its own account giving due consideration to accepted
mortgage servicing practices of prudent lending institutions, the FHA
Insurance Contracts, where applicable, and the Certificateholders' reliance on
the Servicer.

          The Servicer shall give prompt notice to the Trustee of any action,
of which the Servicer has actual knowledge, which action purports to (i)
assert a claim against the Trust Fund or (ii) assert jurisdiction over the
Trust Fund.

          Notwithstanding anything in this Agreement to the contrary, in the
event of a Principal Prepayment in full of a Mortgage Loan, the Servicer may
not waive any Prepayment Charge or portion thereof required by the terms of
the related Mortgage Note unless (i) the Servicer determines that such waiver
would maximize recovery of Liquidation Proceeds for such Mortgage Loan, taking
into account the value of such Prepayment Charge, (ii) (A) the enforceability
thereof is limited (1) by bankruptcy, insolvency, moratorium, receivership, or
other similar law relating to creditors' rights generally or (2) due to
acceleration in connection with a foreclosure or other involuntary payment, or
(B) the enforceability is otherwise limited or prohibited by applicable law or
(iii) the Servicer has not been provided with information sufficient to enable
it to collect the Prepayment Charge. In the event of a Principal Prepayment in
full with respect to any Mortgage Loan, the Servicer shall deliver to the
Trustee an Officer's Certificate substantially in the form of Exhibit N no
later than the date on which the Servicer delivers the Remittance Report to
the Trustee and the Trustee will make such Officer's Certificate available on
its website to the Class X Certificateholders. If the Servicer has waived or
does not collect all or a portion of a Prepayment Charge relating to a
Principal Prepayment in full due to any action or omission of the Servicer,
other than as provided above, the Servicer shall, within 90 days of the date
on which the Principal Prepayment in full is remitted to the Trustee, deliver
to the Trustee the amount of such Prepayment Charge (or such portion thereof
as had been waived for deposit) into the Distribution Account for distribution
in accordance with the terms of this Agreement.

                                      63
<PAGE>

          The Trustee shall make available on its website to the Depositor and
the owner of the Class N and Class X Certificates, on a monthly basis, a
statement setting forth the amounts received with respect to Prepayment
Charges.

          Section 3.02 Collection of Mortgage Loan Payments.

          Continuously from the date hereof until the principal and interest
on all Mortgage Loans are paid in full, the Servicer will diligently collect
all payments due under each Mortgage Loan when the same shall become due and
payable and shall, to the extent such procedures shall be consistent with this
Agreement and Applicable Regulations, follow such collection procedures as it
follows with respect to mortgage loans comparable to the Mortgage Loans and
held for its own account. Further, the Servicer will take special care in
ascertaining and estimating annual ground rents, taxes, assessments, water
rates, fire and hazard insurance premiums, mortgage insurance premiums, and
all other charges that, as provided in the Mortgage, will become due and
payable to that end that the installments payable by the Mortgagors will be
sufficient to pay such charges as and when they become due and payable.

          Section 3.03 Realization Upon Defaulted Mortgage Loans.

          In the event that any payment due under any Conventional Mortgage
Loan is not paid when the same becomes due and payable, or in the event the
Mortgagor fails to perform any other covenant or obligation under the Mortgage
Loan and such failure continues beyond any applicable grace period, the
Servicer shall take such action as it shall deem to be in the best interest of
the Certificateholders. In the event that any payment due under any FHA Loan
becomes delinquent, the Servicer shall take all such actions as are in the
best interests of the Certificateholders and permitted under any applicable
FHA loss mitigation proceedings, including, but not limited to, requesting the
FHA to accept an assignment of such FHA Loan, and, upon the Servicer's
determination that foreclosure is in the best interest of the
Certificateholders, commencing foreclosure proceedings. With respect to any
defaulted Mortgage Loan, the Servicer shall have the right to review the
status of the related forbearance plan and, subject to the second paragraph of
Section 3.01, may modify such forbearance plan; including, extending the
Mortgage Loan repayment date for a period of one year or reducing the Mortgage
Interest Rate up to 50 basis points.

          In connection with a foreclosure or other conversion, the Servicer
shall exercise such rights and powers vested in it hereunder and use the same
degree of care and skill in its exercise as prudent mortgage servicers would
exercise or use under the circumstances in the conduct of their own affairs
and consistent with Applicable Regulations and the servicing standards set
forth in the Fannie Mae Guide, including, without limitation, advancing funds
for the payment of taxes and insurance premiums with respect to first lien
Mortgage Loans.

          Notwithstanding the foregoing provisions of this Section 3.03, with
respect to any Mortgage Loan as to which the 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 Servicer shall not either (i)
obtain title to such Mortgaged Property as a result of or in lieu of
foreclosure or otherwise, or (ii) otherwise acquire possession of, or take any
other action with respect to, such Mortgaged Property if, as a result of any
such action, the Trust Fund would be

                                      64
<PAGE>

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 Servicer has
also previously determined, based on its reasonable judgment and a prudent
report prepared by a Person who regularly conducts environmental audits using
customary industry standards, that:

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

          B. 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 Certificateholders to take
such actions with respect to the affected Mortgaged Property.

          The cost of the environmental audit report contemplated by this
Section 3.03 shall be advanced by the Servicer, subject to the Servicer's
right to be reimbursed therefor from the Collection Account as provided in
Section 3.05(ii).

          If the Servicer determines, as described above, that it is in the
best economic interest of the Certificateholders 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 Servicer shall take such action as it deems to be in the
best economic interest of the Certificateholders. The cost of any such
compliance, containment, cleanup or remediation shall be advanced by the
Servicer, subject to the Servicer's right to be reimbursed therefor from the
Collection Account as provided in Section 3.05(ii).

          Section 3.04 Collection Account and Distribution Account.

          (a) The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan separate and apart from any of its own
funds and general assets and shall establish and maintain one or more
Collection Accounts. Each Collection Account shall be an Eligible Account.

          The Servicer shall deposit in the Collection Account on a daily
basis within two Business Days of receipt, and retain therein, the following
payments and collections received or made by it after the Cut-off Date with
respect to the Mortgage Loans:

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

                                      65
<PAGE>

          (ii) all payments on account of interest on the Mortgage Loans
     adjusted to the Mortgage Interest Rate less the Servicing Fee Rate;

          (iii) all proceeds from a Final Recovery Determination;

          (iv) all Insurance Proceeds including amounts required to be
     deposited pursuant to Section 3.10, other than proceeds to be held in the
     Escrow Account and applied to the restoration or repair of the Mortgaged
     Property or released to the Mortgagor in accordance with the Servicer's
     normal servicing procedures, the loan documents or applicable law;

          (v) all Condemnation Proceeds affecting any Mortgaged Property which
     are not released to the Mortgagor in accordance with the Servicer's
     normal servicing procedures, the loan documents or applicable law;

          (vi) all Subsequent Recoveries; and

          (vii) any amounts required to be deposited by the Servicer in
     connection with any REO Property pursuant to Section 3.13.

          Any interest paid on funds deposited in the Collection Account,
subject to Section 3.25, shall accrue to the benefit of the Servicer and the
Servicer shall be entitled to retain and withdraw such interest from the
Collection Account pursuant to Section 3.05(v). The foregoing requirements for
deposit from the Collection Account shall be exclusive, it being understood
and agreed that, without limiting the generality of the foregoing, payments in
the nature of late payment charges, prepayment charges that are not Prepayment
Charges, and assumption fees need not be deposited by the Servicer in the
Collection Account.

          (b) On behalf of the Trust Fund and the Trustee, the Trustee shall
establish and maintain one or more accounts (such account or accounts, the
"Distribution Account"), held in trust for the benefit of the
Certificateholders. On behalf of the Trust Fund, the Servicer shall deliver to
the Trustee in immediately available funds for deposit in the Distribution
Account by the close of business New York time on the Servicer Remittance
Date, that portion of the Available Funds (calculated without regard to the
references in the definition thereof to amounts that may be deposited to the
Distribution Account from a different source as provided herein) then on
deposit in the Collection Account.

          (c) Funds in the Collection Account and the Distribution Account may
be invested in Permitted Investments in accordance with the provisions set
forth in Section 3.25. The Servicer shall give notice to the Trustee of the
location of the Collection Account maintained by it when established and prior
to any change thereof. The Trustee shall give notice to the Servicer and the
Depositor of the location of the Distribution Account when established and
prior to any change thereof.

          (d) In the event the Servicer shall deliver to the Trustee for
deposit in the Distribution Account any amount not required to be deposited
therein, it may at any time request that the Trustee withdraw such amount from
the Distribution Account and remit to the Servicer any such amount, any
provision herein to the contrary notwithstanding. In addition, the Servicer

                                      66
<PAGE>

shall deliver to the Trustee from time to time for deposit, and the Trustee
shall so deposit, in the Distribution Account in respect of REMIC 1:

          (i) any Advances, as required pursuant to Section 4.07;

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

          (iii) any Prepayment Charges or amounts in connection with the
     waiver of such Prepayment Charges, in each case required to be deposited
     pursuant to Section 3.01;

          (iv) any amounts required to be deposited in the Distribution
     Account pursuant to Sections 2.03, 3.04, 3.15, 3.16, 3.23 or 4.07; and

          (v) any amounts required to be deposited by the Servicer pursuant to
     Section 3.11 in connection with the deductible clause in any blanket
     hazard insurance policy, such deposit being made from the Servicer's own
     funds, without reimbursement therefor.

          (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other
source, the Trustee shall notify the Servicer of such receipt and deposit such
funds in the Distribution Account, subject to withdrawal thereof as permitted
hereunder.

          Section 3.05 Permitted Withdrawals From the Collection Account.

          The Servicer may, from time to time, withdraw from the
Collection Account for the following purposes:

          (i) to remit to the Trustee for deposit in the Distribution Account
     the amounts required to be so remitted pursuant to Section 3.04(b) or
     permitted to be so remitted pursuant to the first sentence of Section
     3.04(d);

          (ii) to reimburse itself for (x) Advances and Servicing Advances;
     the Servicer's right to reimburse itself pursuant to this subclause (ii)
     being limited to amounts received on the related Mortgage Loan which
     represent payments of (a) principal and/or interest respecting which any
     such Advance was made or (b) Condemnation Proceeds, Insurance Proceeds or
     Liquidation Proceeds respecting which any such Servicing Advance was made
     or (y) any unreimbursed Advances made pursuant to Section 4.07(b) to the
     extent of funds held in the Collection Account for future distribution
     that were not included in Available Funds for the preceding Distribution
     Date;

          (iii) to reimburse itself for unreimbursed Servicing Advances, any
     unpaid Servicing Fees and for unreimbursed Advances to the extent that
     such amounts are deemed to be Nonrecoverable Advances, and to reimburse
     itself for such amounts to the extent that such amounts are
     nonrecoverable from the disposition of REO Property pursuant to Section
     3.03 or Section 3.13 hereof;

                                      67
<PAGE>

          (iv) to reimburse itself for any amounts paid pursuant to Section
     3.03 (and not otherwise previously reimbursed);

          (v) to pay to itself as servicing compensation (a) any interest
     earned on funds in the Collection Account (all such interest to be
     withdrawn monthly not later than each Servicer Remittance Date) and (b)
     the Servicing Fee from that portion of any payment or recovery as to
     interest to a particular Mortgage Loan to the extent not retained
     pursuant to Section 3.04(ii);

          (vi) to pay or reimburse itself or any other party for any amounts
     payable or paid pursuant to Section 3.26 or Section 6.03 (and not
     otherwise previously reimbursed); and

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

          The foregoing requirements for withdrawal from the Collection
Account shall be exclusive. In the event the 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.

          Section 3.06 Establishment of Escrow Accounts; Deposits in Escrow
                       Accounts.

          The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan which constitute Escrow Payments
separate and apart from any of its own funds and general assets and shall
establish and maintain one or more Escrow Accounts, in the form of time
deposit or demand accounts. A copy of such letter agreement shall be furnished
to the Trustee upon request. The Escrow Account shall be an Eligible Account.

          The Servicer shall deposit in the Escrow Account or Accounts on a
daily basis within two Business Days of receipt, and retain therein, (i) all
Escrow Payments collected on account of the Mortgage Loans, for the purpose of
effecting timely payment of any such items as required under the terms of this
Agreement, and (ii) all Insurance Proceeds which are to be applied to the
restoration or repair of any Mortgaged Property. The Servicer shall make
withdrawals therefrom only to effect such payments as are required under this
Agreement, and for such other purposes as shall be set forth in, or in
accordance with, Section 3.07. The Servicer shall be entitled to retain any
interest paid on funds deposited in the Escrow Account by the depository
institution other than interest on escrowed funds required by law to be paid
to the Mortgagor and, to the extent required by the related Mortgage Loan or
Applicable Regulations, the Servicer shall pay interest on escrowed funds to
the Mortgagor notwithstanding that the Escrow Account is non-interest bearing
or that interest paid thereon is insufficient for such purposes.

          Section 3.07 Permitted Withdrawals from Escrow Account.

          Withdrawals from the Escrow Account may be made by the Servicer (i)
to effect timely payments of ground rents, taxes, assessments, water rates,
fire, flood and hazard insurance premiums, and comparable items, (ii) to
reimburse the Servicer for any Servicing Advance made

                                      68
<PAGE>

by the Servicer with respect to a related Mortgage Loan but only from amounts
received on the related Mortgage Loan which represent late payments or Late
Collections of Escrow Payments thereunder, (iii) to refund to the Mortgagor
any funds as may be determined to be overages, (iv) for transfer to the
Collection Account in accordance with the terms of this Agreement, (v) for
application to restoration or repair of the Mortgaged Property, (vi) to pay to
the 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, (viii) to transfer to the
Collection Account any insurance proceeds, or (ix) in the case of FHA Loans,
for transfer to the Collection Account, fire and hazard insurance proceeds and
Escrow Payments with respect to any Mortgage Loan where the FHA has directed
application of such funds as a credit against the proceeds of the FHA
Insurance Contract. As part of its servicing duties, the 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.

          In the event the Servicer shall deposit in the Escrow Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from the Escrow Account, any provision herein to the contrary
notwithstanding.

          Section 3.08 Payment of Taxes, Insurance and Other Charges;
                       Collections Thereunder.

          With respect to each first lien Mortgage Loan, the 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 fire, flood and hazard insurance coverage and 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 Servicer in amounts sufficient for such purposes, as
allowed under the terms of the Mortgage or Applicable Regulations. To the
extent that a Mortgage does not provide for Escrow Payments, the Servicer (i)
shall determine whether any such payments are made by the Mortgagor in a
manner and at a time that is necessary to avoid the loss of the Mortgaged
Property due to a tax sale or the foreclosure as a result of a tax lien and
(ii) shall ensure that all insurance required to be maintained on the
Mortgaged Property pursuant to this Agreement is maintained. If any such
payment has not been made and the Servicer receives notice of a tax lien with
respect to the Mortgage Loan being imposed, the Servicer will, to the extent
required to avoid loss of the Mortgaged Property, advance or cause to be
advanced funds necessary to discharge such lien on the Mortgaged Property. The
Servicer assumes full responsibility for the payment of all such bills and
shall effect 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.

                                      69
<PAGE>

          Section 3.09 Transfer of Accounts.

          The Servicer may transfer the Collection Account or the Escrow
Account to a different depository institution from time to time. Upon such
transfer, the Servicer shall deliver to the Trustee and the Depositor, a
certification or letter agreement, as the case may be, as required pursuant to
Sections 3.04 and 3.06.

          Section 3.10 Maintenance of Hazard Insurance.

          The Servicer shall cause to be maintained for each first lien
Mortgage Loan fire and hazard insurance with extended coverage as is customary
in the area where the Mortgaged Property is located in an amount which is at
least equal to the lesser of (i) the amount necessary to fully compensate for
any damage or loss to the improvements which are a part of such property on a
replacement cost basis, (ii) the Principal Balance of the Mortgage Loan, in
each case in an amount not less than such amount as is necessary to prevent
the Mortgagor and/or the Mortgagee from becoming a co-insurer or (iii) the
amount required under applicable HUD/FHA regulations. If the Mortgaged
Property is in an area identified in the Federal Register by the Flood
Emergency Management Agency as having special flood hazards and flood
insurance has been made available, the Servicer will cause to be maintained a
flood insurance policy meeting the requirements of the current guidelines of
the Federal Insurance Administration with a generally acceptable insurance
carrier, in an amount representing coverage not less than the least of (i) the
Principal Balance of the Mortgage Loan, (ii) the maximum insurable value of
the improvements securing such Mortgage Loan or (iii) the maximum amount of
insurance which is available under the Flood Disaster Protection Act of 1973,
as amended. The Servicer shall also maintain on the REO Property for the
benefit of the Certificateholders, (x) fire and hazard insurance with extended
coverage in an amount which is at least equal to the replacement cost of the
improvements which are a part of such property, (y) public liability insurance
and, (z) to the extent required and available under the Flood Disaster
Protection Act of 1973, as amended, flood insurance in an amount as provided
above. Any amounts collected by the Servicer under any such policies other
than amounts to be deposited in the Escrow Account and applied to the
restoration or repair of the Mortgaged Property or REO Property, or released
to the Mortgagor in accordance with the Servicer's normal servicing
procedures, shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.05. It is understood and agreed that no
earthquake or other additional insurance is required to be maintained by the
Servicer or the Mortgagor or maintained on property acquired in respect of the
Mortgage Loan, other than pursuant to such Applicable Regulations as shall at
any time be in force and as shall require such additional insurance. All such
policies shall be endorsed with standard mortgagee clauses with loss payable
to the Servicer and shall provide for at least thirty days prior written
notice of any cancellation, reduction in the amount of or material change in
coverage to the Servicer. The Servicer shall not interfere with the
Mortgagor's freedom of choice in selecting either his insurance carrier or
agent, PROVIDED, HOWEVER, that the Servicer shall not accept any such
insurance policies from insurance companies unless such companies currently
reflect a general policy rating of B:VI or better in Best's Key Rating Guide
and are licensed to do business in the state wherein the property subject to
the policy is located.

          Section 3.11 Maintenance of Mortgage Impairment Insurance Policy.

          In the event that the Servicer shall obtain and maintain a blanket
policy issued by an insurer that has a general policy rating of B:VI or better
in Best's Key Rating Guide insuring against hazard losses on all of the
Mortgage Loans, then, to the extent such policy provides coverage in an amount
equal to the amount required pursuant to Section 3.10 and otherwise complies
with all other requirements of Section 3.10, it shall conclusively be deemed
to have satisfied its obligations as set forth in Section 3.10, it being
understood and agreed that such policy may contain a deductible clause, in
which case the Servicer shall, in the event that there shall not have been
maintained on the related Mortgaged Property or REO Property a policy
complying with Section 3.10, and there shall have been a loss which would have
been covered by such policy, deliver to the Trustee for deposit in the
Distribution Account the amount not otherwise payable under the blanket policy
because of such deductible clause, which amount shall not be reimbursable to
the Servicer from the Trust Fund. In connection with its activities as
servicer of the Mortgage Loans, the Servicer agrees to prepare and present, on
behalf of the Trustee, claims under any such blanket policy in a timely
fashion in accordance with the terms of such policy. Upon request of the
Trustee, the Servicer shall cause to be delivered to the Trustee a certified
true copy of such policy and a statement from the insurer thereunder that such
policy shall in no event be terminated or materially modified without thirty
days prior written notice to the Trustee.

          Section 3.12 Fidelity Bond, Errors and Omissions Insurance.

          The Servicer shall maintain, at its own expense, a blanket fidelity
bond (the "Fidelity Bond") and an errors and omissions insurance policy, with
broad coverage with financially responsible companies on all officers,
employees or other persons acting in any capacity with regard to the Mortgage
Loans to handle funds, money, documents and papers relating to the Mortgage
Loans. The Fidelity Bond and errors and omissions insurance shall be in the
form of the Mortgage Banker's Blanket Bond and shall protect and insure the
Servicer against losses, including forgery, theft, embezzlement, fraud, errors
and omissions and negligent acts of such persons. Such Fidelity Bond shall
also protect and insure the Servicer against losses in connection with the
failure to maintain any insurance policies required pursuant to this Agreement
and the release or satisfaction of a Mortgage Loan without having obtained
payment in full of the indebtedness secured thereby. No provision of this
Section 3.12 requiring the Fidelity Bond and errors and omissions insurance
shall diminish or relieve the Servicer from its duties and obligations as set
forth in this Agreement. The minimum coverage under any such bond and
insurance policy shall be at least equal to the corresponding amounts required
by Fannie Mae in the Fannie Mae MBS Selling and Servicing Guide or by Freddie
Mac in the Freddie Mac Servicer's Guide. Upon request of the Trustee, the
Servicer shall cause to be delivered to the requesting party a certified true
copy of the Fidelity Bond and errors and omissions insurance policy and a
statement from the surety and the insurer that such Fidelity Bond and errors
and omissions insurance policy shall in no event be terminated or materially
modified without thirty days' prior written notice to the Trustee.

          Section 3.13 Title, Management and Disposition of REO Property.

          (a) In the event that title to a Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken (pursuant to a limited power of attorney to be provided by the
Trustee to the Servicer) in the name of the Trustee, on behalf of the
Certificateholders, or in the event the Trustee is not authorized or permitted
to hold title to real property in the state where the REO Property is located,
or would be adversely affected under the "doing business" or tax laws of such
state by so holding title, the deed or certificate of sale shall be taken in
the name of such Person or Persons as shall be consistent with an Opinion of
Counsel obtained by the Servicer from an attorney duly licensed to practice
law in the state where the REO Property is located. Any Person or Persons
holding such title other than the Trustee shall acknowledge in writing that
such title is being held as nominee for the benefit of the Trustee.

          (b) In the event that the Trust Fund acquires any REO Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end
of the third calendar year beginning after the year of its acquisition by the
Trust Fund for purposes of Section 860G(a)(8) of the Code or, at the expense
of the Trust Fund, request from the Internal Revenue Service, more than 60
days before the day on which the above-mentioned grace period would otherwise
expire, an extension of the above-mentioned grace period, unless the Servicer
obtains an Opinion of Counsel, addressed to the Servicer and the Trustee, to
the effect that the holding by the Trust Fund of such REO Property subsequent
to such period will not: (i) result in the imposition of any tax on
"prohibited transactions" as defined in Section 860F of the Code; or (ii)
cause any REMIC constituting any part of the Trust Fund to fail to qualify as
a REMIC at any time that any Certificates are outstanding, in which case the
Trust Fund may continue to hold such REO Property (subject to any conditions
contained in such Opinion of Counsel). The Servicer shall be entitled to be
reimbursed from the Collection Account for any costs incurred in obtaining
such Opinion of Counsel, as provided in Section 3.05.

          Subject to compliance with applicable laws and regulations as shall
at any time be in force, and notwithstanding any other provisions of this
Agreement, no REO Property acquired by the Trust Fund shall be rented (or
allowed to continue to be rented) or otherwise used by or on behalf of the
Trust Fund in such a manner or pursuant to any terms that would: (i) cause
such REO Property to fail to qualify as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code; or (ii) subject any REMIC
constituting part of the Trust Fund to the imposition of any federal income
taxes on the income earned from such REO Property, including any taxes imposed
by reason of Sections 860F or 860G(c) of the Code, unless the Servicer has
agreed to indemnify and hold harmless the Trust Fund with respect to the
imposition of any such taxes.

          The Servicer shall manage, conserve, protect and operate each REO
Property for the Certificateholders and the Trust Fund 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 the related 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

                                      72
<PAGE>

the REMIC Provisions. The Servicer shall cause each REO Property to be
inspected promptly upon the acquisition of title thereto and shall cause each
REO Property to be inspected at least annually thereafter. The Servicer shall
make or cause to be made a written report of each such inspection. Such
reports shall be retained in the Mortgage Servicing File and copies thereof
shall be forwarded by the Servicer to the Trustee upon request. The Servicer
shall attempt to sell the same (and may temporarily rent the same) on such
terms and conditions as the Servicer deems to be in the best interest of the
Certificateholders and the Trust Fund.

          With respect to each REO Property, the Servicer shall account
separately for each REO Property with respect to all funds collected and
received in connection with the operation of such REO Property.

          The Servicer shall deposit or cause to be deposited, on a daily
basis, within two Business Days of receipt, in the Collection Account, all
revenues received with respect to each REO Property and shall withdraw
therefrom funds necessary for the proper operation, management and maintenance
of the related REO Property, including the cost of maintaining any hazard
insurance pursuant to Section 3.10 hereof and the fees of any managing agent
acting on behalf of the Servicer.

          The Servicer shall furnish to the Trustee, on each Servicer
Remittance Date, an operating statement for each REO Property covering the
operation of each REO Property for the previous month. Such operating
statement shall be accompanied by such other information as the Trustee shall
reasonably request.

          The Servicer shall use its best efforts to dispose of the REO
Property as promptly as is practically consistent with protecting the
Certificateholders' interests.

          Each REO Disposition shall be carried out by the Servicer at such
price and upon such terms and conditions as the Servicer deems to be in the
best interest of the Certificateholders. If as of the date title to any REO
Property was acquired by the Servicer there were outstanding unreimbursed
Servicing Advances with respect to the REO Property, the Servicer, upon an REO
Disposition of such REO Property, shall be entitled to reimbursement for any
related unreimbursed Servicing Advances from proceeds received in connection
with such REO Disposition. The proceeds from the REO Disposition, net of any
payment to the Servicer as provided above, shall be deposited in the
Collection Account for distribution on the succeeding Servicer Remittance Date
in accordance with Section 4.01 and Section 4.02.

          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 and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

          Section 3.14 Due-On-Sale Clauses; Assumption and Substitution
                       Agreements.

          When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, to the extent it has knowledge of such
conveyance or prospective conveyance, exercise its rights to accelerate the
maturity of the related Mortgage Loan under any "due-on-sale" clause contained
in the related Mortgage or Mortgage Note; PROVIDED,

                                      73
<PAGE>

HOWEVER, that the Servicer shall not exercise any such right if the
"due-on-sale" clause, in the reasonable belief of the Servicer, is not
enforceable under applicable law. An Opinion of Counsel at the expense of the
Servicer (which expense shall constitute a Servicing Advance) delivered to the
Trustee and the Depositor to the foregoing effect shall conclusively establish
the reasonableness of such belief. In such event, the Servicer shall make
reasonable efforts to enter into an assumption and modification agreement with
the Person to whom such property has been or is about to be conveyed, pursuant
to which such Person becomes liable under the Mortgage Note and, unless
prohibited by applicable law or the Mortgage, the Mortgagor remains liable
thereon. If the foregoing is not permitted under applicable law, the Servicer
is 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 Mortgagor and becomes liable under the Note.
The Mortgage Loan, as assumed, shall conform in all respects to the
requirements, representations and warranties of this Agreement. The Servicer
shall notify the Trustee that any such assumption or substitution agreement
has been completed by forwarding to the Trustee (or the Custodian, as the case
may be) the original copy of such assumption or substitution agreement
(indicating the Mortgage File to which it relates) which copy shall be added
by the Trustee (or the Custodian, as the case may be) to the related Mortgage
File and which 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. The Servicer shall be responsible for recording any such
assumption or substitution agreements. In connection with any such assumption
or substitution agreement, the Monthly Payment on the related Mortgage Loan
shall not be changed but shall remain as in effect immediately prior to the
assumption or substitution, the stated maturity or outstanding principal
amount of such Mortgage Loan shall not be changed nor shall any required
monthly payments of principal or interest be deferred or forgiven. Any fee
collected by the Servicer for consenting to any such conveyance or entering
into an assumption or substitution agreement shall be retained by or paid to
the Servicer as additional servicing compensation.

          Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the 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 any assumption which the Servicer
may be restricted by law from preventing, for any reason whatsoever.

          Section 3.15 Notification of Adjustments.

          On each Adjustment Date, the Servicer shall make Mortgage Interest
Rate adjustments for each Adjustable-Rate Mortgage Rate Loan in compliance
with the requirements of the related Mortgage and Mortgage Note and Applicable
Regulations. The Servicer shall execute and deliver the notices required by
each Mortgage and Mortgage Note and Applicable Regulations regarding Mortgage
Interest Rate adjustments. The Servicer also shall provide timely notification
to the Trustee of all applicable data and information regarding such Mortgage
Interest Rate adjustments and the Servicer's methods of implementing such
Mortgage Interest Rate adjustments. Upon the discovery by the Servicer or the
Trustee that the Servicer has failed to adjust or has incorrectly adjusted a
Mortgage Interest Rate or a Monthly Payment pursuant to the terms of the
related Mortgage Note and Mortgage, the Servicer shall deliver to the Trustee
for deposit in the Distribution Account from its own funds the amount of any
interest loss caused

                                      74
<PAGE>

thereby without reimbursement therefor; PROVIDED, HOWEVER, the Servicer shall
be held harmless with respect to any Mortgage Interest Rate adjustments made
by any servicer prior to the Servicer.

          Section 3.16 Optional Purchases of Mortgage Loans by Servicer.

          The Servicer (or an affiliate of the Servicer) may, at its option,
repurchase a Mortgage Loan or REO Property which becomes 120 or more days
Delinquent or for which the Servicer has accepted a deed in lieu of
foreclosure, during the period commencing on the first day of the calendar
quarter succeeding the calendar quarter in which the Initial Delinquency Date
occurred with respect to such Mortgage Loan and ending on the last Business
Day of such calendar quarter. If the Servicer (or an affiliate of the
Servicer) does not exercise its purchase right with respect to a Mortgage Loan
during the period specified in the preceding sentence, such Mortgage Loan
shall thereafter again become eligible for purchase pursuant to the preceding
sentence only after the Mortgage Loan ceases to be 120 days or more Delinquent
and thereafter becomes 120 days Delinquent again. The "Initial Delinquency
Date" of a Mortgage Loan shall mean the date on which the Mortgage Loan first
became 120 days Delinquent. Prior to repurchase pursuant to this Section 3.16,
the Servicer shall be required to continue to make monthly advances pursuant
to Section 4.07. The Servicer shall not use any procedure in selecting
Mortgage Loans to be repurchased which is materially adverse to the interests
of the Certificateholders. The Servicer shall purchase such (i) delinquent
Mortgage Loan at a price equal to the Principal Balance of the Mortgage Loan
plus accrued interest thereon at the Mortgage Interest Rate from the date to
which interest has last been paid to the Trust Fund to the date of purchase
plus any unreimbursed Servicing Advances and Advances or (ii) REO Property at
its fair market value as determined in good faith by the Servicer. Any such
repurchase of a Mortgage Loan or REO Property pursuant to this Section 3.16
shall be accomplished by delivery to the Trustee for deposit in the
Distribution Account of the amount of the purchase price. The Trustee shall
immediately effectuate the conveyance of such delinquent Mortgage Loan or REO
Property to the Servicer to the extent necessary, including the prompt
delivery of all documentation to the Servicer.

          Section 3.17 Trustee to Cooperate; Release of Files.

          (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such Mortgage Loan through foreclosure or otherwise, or the
receipt by the Servicer of a notification that payment in full will be
escrowed in a manner customary for such purposes), the Servicer shall deliver
to the Trustee (or the Custodian as the case may be) two executed copies of a
completed "Request for Release" in the form of Exhibit E. Upon receipt of such
Request for Release of Documents, the Trustee (or the Custodian as the case
may be) shall promptly release the related Mortgage File, in trust to (i) the
Servicer, or (ii) such other party identified in the related Request for
Release. Upon any such payment in full, or the receipt of such notification
that such funds have been placed in escrow, the Servicer shall direct the
Trustee in writing to execute an instrument of satisfaction (or assignment of
Mortgage without recourse) regarding the Mortgaged Property relating to such
Mortgage, which instrument of satisfaction or assignment, as the case may be,
shall be delivered to the Person or Persons entitled thereto against receipt
therefor of payment in full, it being understood and agreed that no expense
incurred in connection with such instrument of satisfaction or assignment, as
the case may be, shall be

                                      75
<PAGE>

chargeable to the Collection Account. In lieu of executing any such
satisfaction or assignment, as the case may be, the Servicer may prepare and
submit to the Trustee a satisfaction (or assignment without recourse, if
requested by the Person or Persons entitled thereto) in form for execution by
the Trustee with all requisite information completed by the Servicer; in such
event, the Trustee shall execute and acknowledge such satisfaction or
assignment, as the case may be, and deliver the same with the related Mortgage
File, as aforesaid.

          (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any insurance policy
relating to a Mortgage Loan, the Trustee shall (except in the case of the
payment or liquidation pursuant to which the related Mortgage File is released
to an escrow agent or an employee, agent or attorney of the Trustee), upon
written request of the Servicer and delivery to the Trustee (or the Custodian,
as the case may be) of two executed copies of a "Request for Release" in the
form of Exhibit E signed by a Servicing Officer, release the related Mortgage
File to the Servicer and shall execute such documents as shall be necessary to
the prosecution of any such proceedings, including, without limitation, an
assignment without recourse, representation or warranty of the related
Mortgage to the Servicer. Such receipt shall obligate the Servicer to return
the Mortgage File to the Trustee (or the Custodian, as the case may be) when
the need therefor by the Servicer no longer exists unless the Mortgage Loan
shall be liquidated, in which case, upon receipt of a Request for Release
evidencing such liquidation, the receipt shall be released by the Trustee (or
the Custodian, as the case may be) to the Servicer.

          (c) Subject to Section 3.01, the Servicer shall have the right to
accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, (iii) removal, demolition or division of
properties subject to Mortgages and (iv) second mortgage subordination
agreements. No application for approval shall be considered by the Servicer
unless: (w) it has received an Opinion of Counsel, addressed to the Trustee
(which opinion shall not be an expense of the Trustee or the Trust Fund) that
such sale, disposition, substitution, acquisition or contribution will not
affect adversely the status of any REMIC constituting part of the Trust Fund
as a REMIC or cause any REMIC constituting part of the Trust Fund to be
subject to a tax on "prohibited transactions" or "contributions" pursuant to
the REMIC Provisions; (x) the provisions of the related Note and Mortgage have
been complied with; (y) the Combined Loan-to-Value Ratio and debt-to- income
ratio after any release does not exceed the maximum Combined Loan-to-Value
Ratio and debt-to-income ratio established in accordance with the underwriting
standards of the Mortgage Loans; and (z) the lien priority of the related
Mortgage is not affected. Upon receipt by the Trustee of a Servicing Officer's
certificate setting forth the action proposed to be taken in respect of a
particular Mortgage Loan and certifying that the criteria set forth in the
immediately preceding sentence have been satisfied, the Trustee shall execute
and deliver to the Servicer the consent or partial release so requested by the
Servicer. A proposed form of consent or partial release, as the case may be,
shall accompany any Servicing Officer's certificate delivered by the Servicer
pursuant to this paragraph.

          Section 3.18 Servicing Compensation.

          As compensation for its activities hereunder, the Servicer shall be
entitled to retain the amount of the Servicing Fee with respect to each
Mortgage Loan (including REO

                                      76
<PAGE>

Properties). The Servicer shall be entitled to retain additional servicing
compensation in the form of release fees, bad check charges, assumption fees,
modification or extension fees, late payment charges, customary real estate
referral fees or any other service-related fees, Insurance Proceeds and
Liquidation Proceeds not required to be deposited in the Collection Account
and similar items, to the extent collected from Mortgagors.

          Section 3.19 Statement as to Compliance.

          (a) The Servicer, at its own expense, will deliver to the Trustee
and the Depositor, not later than March 15th of each calendar year commencing
in 2005, a Servicing Officer's certificate stating, as to each signer thereof,
that (i) a review of the activities of the Servicer during such preceding
calendar year (or such shorter period in the case of the first such report)
and of performance under this Agreement has been made under such officers'
supervision, and (ii) to the best of such officers' knowledge, based on such
review, the Servicer has fulfilled all its obligations under this Agreement
for such year, or, if there has been a default in the fulfillment of all such
obligations, specifying each such default known to such officers and the
nature and status thereof including the steps being taken by the Servicer to
remedy such default.

          (b) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and their receipt of such shall not
constitute constructive notice of any information contained therein or
determinable, from information contained therein, including the Servicer's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

          Section 3.20 Annual Independent Certified Public Accountants'
                       Reports.

          (a) Not later than March 15th of each calendar year commencing in
2005, the Servicer, at its expense, shall cause a nationally recognized firm
of independent certified public accountants to furnish to the Trustee and the
Depositor a report stating that (i) it has obtained a letter of representation
regarding certain matters from the management of the Servicer which includes
an assertion that the Servicer has complied with certain minimum residential
mortgage loan servicing standards, identified in either the Uniform Single
Attestation Program for Mortgage Bankers established by the Mortgage Bankers
Association of America or the Audit Program for Mortgages serviced by Freddie
Mac, 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. Immediately upon receipt of such
report, the Servicer shall furnish a copy of such report to the Trustee, the
Depositor and each Rating Agency. Copies of such statement shall be provided
by the Trustee to any Certificateholder upon request at the Servicer's
expense, provided that such statement is delivered by the Servicer to the
Trustee.

          (b) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and its receipt of such shall not
constitute constructive notice of any information contained therein or
determinable, from information contained therein, including the

                                      77
<PAGE>

Servicer's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

          Section 3.21 Access to Certain Documentation and Information
                       Regarding the Mortgage Loans.

          The Servicer shall provide to the Trustee, Certificateholders or
Certificate Owners that are federally insured savings and loan associations,
the Office of Thrift Supervision, the FDIC and the supervisory agents and
examiners of each of the foregoing (which, in the case of supervisory agents
and examiners, may be required by applicable state and federal regulations)
access to the documentation regarding the Mortgage Loans, such access being
afforded without charge but only upon reasonable request and during normal
business hours at the offices of the Servicer designated by it.

          Section 3.22 Commission Reporting.

          (a) The Trustee and the Servicer shall reasonably cooperate with the
Depositor in connection with satisfying the reporting requirements under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Trustee
shall prepare and file (via the Securities and Exchange Commission's
Electronic Data Gathering and Retrieval System) on behalf of the Trust Fund
any Forms 8-K and 10-K (and the Servicer shall sign any Form 10-K) customary
for similar securities as required by the Exchange Act and the Rules and
Regulations of the Securities and Exchange Commission thereunder. The
Depositor agrees to cooperate with the Trustee and Trustee's counsel to assist
the Trustee in determining the form and content of any filings that may be
required pursuant to this Section 3.22, and, without limiting the Trustee's
responsibility hereunder, otherwise to assist the Trustee in fulfilling its
duties under this Section 3.22.

          (b) Each Form 8-K shall be filed by the Trustee within 15 days after
each Distribution Date, with a copy of the statement to the Certificateholders
for such Distribution Date as an exhibit thereto. Prior to March 30th of each
year (or such earlier date as may be required by the Exchange Act and the
Rules and Regulations of the Securities and Exchange Commission), the Trustee
shall file a Form 10-K, in substance as required by applicable law or
applicable Security and Exchange Commission staff's interpretations. Such Form
10-K shall include as exhibits the 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. The Trustee shall have no liability with respect to (a) 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, willful misconduct or bad faith or (b) any
inaccuracy in such periodic reports resulting from incorrect information
provided to the Trustee by the Servicer in a Remittance Report or otherwise.
The Form 10-K shall also include a certification in the form attached hereto
as Exhibit O-1 (the "Certification"), which shall be signed by the senior
officer of the Servicer in charge of servicing.

          (c) In addition, the Trustee shall sign a certification (in the form
attached hereto as Exhibit O-2) for the benefit of the Servicer and its
officers, directors and Affiliates

                                      78
<PAGE>

regarding certain aspects of the Certification (the "Trustee 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). Such
certification shall be delivered to the Servicer no later than the 20th day
prior to the latest date on which the Form 10-K is permitted to be filed,
without regard to extension (or if such day is not a Business Day, the
immediately preceding Business Day) and the Servicer shall deliver the
Certification to be filed to the Trustee no later than the 10th day prior to
the latest date on which the Form 10-K is permitted to be filed, without
regard to extension (or if such day is not a Business Day, the immediately
preceding Business Day).

          In addition, (i) the Trustee shall, subject to the provisions of
Sections 8.01 and 8.02 hereof, indemnify and hold harmless the Depositor, the
Servicer and each of 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) a breach of the Trustee's obligations under this
Section 3.22(b), (b) the Trustee's negligence, bad faith or willful misconduct
in connection therewith or (c) any inaccuracy in the Trustee Certification and
(ii) the Servicer shall indemnify and hold harmless the Depositor, the Trustee
and their respective officers, directors and Affiliates from and against any
actual 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) the failure of the Servicer to timely deliver
the Certification or (b) any material misstatement in the Certification. If
the indemnification provided for herein is unavailable or insufficient to hold
harmless the Depositor, then (i) the Trustee agrees that it shall contribute
to the amount paid or payable by the Depositor as a result of the losses,
claims, damages or liabilities of the Depositor in such proportion as is
appropriate to reflect the relative fault of the Depositor on the one hand and
the Trustee on the other in connection with a breach of the Trustee's
obligations under this Section 3.22(b) or the Trustee's negligence, bad faith
or willful misconduct in connection therewith and (ii) the Servicer agrees
that it shall contribute to the amount paid or payable by the Depositor as a
result of the losses, claims, damages or liabilities of the Depositor in such
proportion as is appropriate to reflect the relative fault of the Depositor on
the one hand and the Servicer on the other in connection with a breach of the
Servicer's obligations under this Section 3.22(b) or the Servicer's
negligence, bad faith or willful misconduct in connection therewith.

          (d) Upon any filing with the Securities and Exchange Commission, the
Trustee shall promptly deliver to the Depositor and the Servicer 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 Fund.

          (f) To the extent that, following the Closing Date, the Depositor
certifies that reports and certifications differing from those required under
this Section 3.22 comply with the reporting requirements under the Exchange
Act, the Trustee and the Servicer hereby agree that they will reasonably
cooperate to amend the provisions of this Section 3.22 in order to comply with
such amended reporting requirements and such amendment of this Section 3.22.
Any such amendment may result in the reduction of the reports filed by the
Depositor under the Exchange Act. Notwithstanding the foregoing, the parties
hereto shall not be obligated to enter into any

                                      79
<PAGE>

amendment pursuant to this Section 3.22 that adversely affects its obligations
and immunities under this Agreement.

          Section 3.23 Obligations of the Servicer in Respect of Compensating
                       Interest.

          Not later than the close of business on each Servicer Remittance
Date, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account an amount ("Compensating Interest") equal to the lesser
of (A) the aggregate of the Prepayment Interest Shortfalls on the Actuarial
Mortgage Loans for the related Distribution Date resulting from Principal
Prepayments in full on the Actuarial Mortgage Loans during the related
Prepayment Period and (B) 50% of its aggregate Servicing Fee received in the
related Collection Period. Compensating Interest shall be applied to offset
any Prepayment Interest Shortfalls on the Actuarial Mortgage Loans. The
Servicer shall not have the right to reimbursement for any amounts remitted to
the Trustee in respect of Compensating Interest. Such amounts so remitted
shall be included in the Available Funds and distributed therewith on the next
Distribution Date. The Servicer shall not be obligated to pay Compensating
Interest with respect to Prepayment Interest Shortfalls on Simple Interest
Mortgage Loans or Relief Act Interest Shortfalls.

          Section 3.24 Obligations of the Servicer in Respect of Mortgage
                       Interest Rates and Monthly Payments.

          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 Interest Rates, Monthly Payments or Principal Balances that were made
by the Servicer in a manner not consistent with the terms of the related
Mortgage Note and this Agreement, the 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 servicer in respect of any such liability. Such indemnities
shall survive the termination or discharge of this Agreement.

          Section 3.25 Investment of Funds in the Collection Account and the
                       Distribution Account.

          (a) The Servicer may direct any depository institution maintaining
the Collection Account (for purposes of this Section 3.25, an "Investment
Account"), to invest the funds in such Investment Account in one or more
Permitted Investments bearing interest or sold at a discount, and maturing,
unless payable on demand, (i) no later than the Business Day immediately
preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Trustee is the
obligor thereon, and (ii) no later than the date on which such funds are
required to be withdrawn from such 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 or the Servicer,
as applicable (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) over each
such investment and 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 at the direction of the Servicer:

          (x) 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

          (y) 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 and gain realized from the investment of funds in the
Collection Account shall be for the benefit of the Servicer. The Servicer
shall deposit in the Collection Account 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) 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 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.

          The Trustee shall not in any way be held liable by reason of any
insufficiency in any Account held by the Trustee resulting from any investment
loss on any Permitted Investment included therein (except to the extent that
the Trustee is the obligor and has defaulted thereon).

          Section 3.26 Liability of Servicer; Indemnification.

          (a) Subject to clause (b) below and Section 6.03, the Servicer
(except the Trustee if it is required to succeed the Servicer hereunder)
indemnifies and holds the Trustee, the Seller, the Depositor and each
Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and
any other costs, fees and expenses that the Trustee, the Depositor and any
Certificateholder may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in compliance
with the Servicing Standards. The Servicer shall immediately notify the
Trustee, the Depositor and each Certificateholder if a claim is made that may
result in such claims, losses, penalties, fines, forfeitures, legal fees or
related costs, judgments, or any other costs, fees and expenses, and the
Servicer shall assume (with the consent of the Trustee) the defense of any
such claim and pay all expenses in connection therewith, including reasonable
counsel fees, and promptly pay, discharge and satisfy any judgment or decree
which may be entered against the Servicer, the Trustee, the Depositor and/or
Certificateholder in respect of

                                      81
<PAGE>

such claim. The provisions of this Section 3.26 shall survive the termination
of this Agreement and the payment of the outstanding Certificates.

          (b) None of the Depositor, the Seller, the Servicer, or any of the
directors, officers, employees or agents of the Depositor, the Seller or the
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 Seller or the Servicer or any such Person against any breach of
warranties or representations made herein, or against any specific liability
imposed on the Servicer for a breach of the Servicing Standard, or against any
liability which would otherwise be imposed by reason of its respective willful
misfeasance, bad faith, fraud or negligence in the performance of its duties
or by reasons of negligent disregard of its respective obligations or duties
hereunder.

          The Depositor, the Servicer, the Seller and any director, officer,
employee or agent of the Depositor, the Seller or the Servicer, may rely in
good faith on any document of any kind which, prima facie, is properly
executed and submitted by any appropriate Person with respect to any matters
arising hereunder. The Depositor, the Servicer, the Seller, and any director,
officer, employee or agent of the Depositor, the Seller or the 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
incurred in connection with any legal action incurred by reason of its
respective misfeasance, bad faith, fraud or negligence, a breach of a
representation or warranty hereunder or (in the case of the Servicer) a breach
of the Servicing Standard in the performance of its respective duties or by
reason of negligent disregard of its respective obligations or duties
hereunder. Neither the Depositor, the Seller nor the 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 expose it to any expense or liability; PROVIDED, HOWEVER,
that the Depositor, the Seller or the Servicer may in its discretion undertake
any action related to its obligations hereunder 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.

          Section 3.27 Reports of Foreclosure and Abandonment of Mortgaged
                       Properties.

          On or before the last day of February of each year beginning in
2005, the Servicer shall file the reports of foreclosure and abandonment of
any Mortgaged Property required by Section 6050J of the Code with the Internal
Revenue Service and provide an Officer's Certificate certifying its compliance
with this Section 3.27 to the Trustee. The reports from the Servicer shall be
in form and substance sufficient to meet the reporting requirements imposed by
such Section 6050J.

          Section 3.28 Protection of Assets.

          (a) Except for transactions and activities entered into in
connection with the securitization that is the subject of this Agreement, the
Trust is not authorized and has no power to:

          (1) borrow money or issue debt;

          (2) merge with another entity, reorganize, liquidate or sell assets;
              or

          (3) engage in any business or activities.

          (b) Each party to this Agreement agrees that it will not file an
involuntary bankruptcy petition against the Trustee or the Trust Fund or
initiate any other form of insolvency proceeding until after the Certificates
have been paid.

          Section 3.29 LIBOR Carryover Reserve Account.

          No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, segregated trust account titled, "LIBOR
Carryover Reserve Account, U.S. Bank National Association, as Trustee, in
trust for the registered Holders of 2004-CB4 Trust, C-BASS Mortgage Loan
Asset-Backed Certificates, Series 2004-CB4." On the Closing Date, the
Depositor will deposit, or cause to be deposited, into the LIBOR Carryover
Reserve Account $5,000.

          On each Distribution Date as to which there is a LIBOR Carryover
Amount payable to the Class A-1 Certificates, the Trustee has been directed by
the Class X/N Certificateholders to, and therefore will, deposit into the
LIBOR Carryover Reserve Account the amounts described in Section
4.02(B)(xxviii), rather than distributing such amounts to the Class X/N
Certificateholders. On each such Distribution Date, the Trustee shall hold all
such amounts for the benefit of the Holders of the Class A-1 Certificates, and
will distribute such amounts to the Holders of the Class A-1 Certificates in
the amounts and priorities set forth in Section 4.02(B). If no LIBOR Carryover
Amounts are payable on a Distribution Date, the Trustee shall deposit into the
LIBOR Carryover Reserve Account on behalf of the Class X/N Certificateholders,
from amounts otherwise distributable to the Class X/N Certificateholders, an
amount such that when added to other amounts already on deposit in the LIBOR
Carryover Reserve Account, the aggregate amount on deposit therein is equal to
$5,000.

          For federal and state income tax purposes, the Class X/N
Certificateholders will be deemed to be the owners of the LIBOR Carryover
Reserve Account and all amounts deposited into the LIBOR Carryover Reserve
Account shall be treated as amounts distributed by REMIC 6 to the Holders of
the Class X/N Certificates. Upon the termination of the Trust, or the payment
in full of the Class A-1 Certificates, all amounts remaining on deposit in the
LIBOR Carryover Reserve Account will be released by the Trust and distributed
to the Class X/N Certificateholders or their designees. The LIBOR Carryover
Reserve Account will be part of the Trust but not part of any REMIC and any
payments to the Holders of the Class A-1 Certificates of LIBOR Carryover
Amounts will not be payments with respect to a "regular interest" in a REMIC
within the meaning of Code Section 860(G)(a)(1).

                                      83
<PAGE>

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

          Amounts on deposit in the LIBOR Carryover Reserve Account shall
remain uninvested.

          For federal tax return and information reporting, the value of the
right of the Class A-1 Certificateholders to receive payments from the LIBOR
Carryover Reserve Account in respect of any LIBOR Carryover Amount may be
obtained from the Trustee upon request.

          Section 3.30 Advance Facility.

          (a) The Servicer is hereby authorized to enter into a financing or
other facility (any such arrangement, an "Advance Facility"), the
documentation for which complies with Section 3.30(e) below, under which (1)
the Servicer assigns or pledges its rights under this Agreement to be
reimbursed for any or all Advances and/or Servicing Advances to (i) a Person,
which may be a special-purpose bankruptcy-remote entity (an "SPV"), (ii) a
Person, which may simultaneously assign or pledge such rights to an SPV or
(iii) a lender (a "Lender"), which, in the case of any Person or SPV of the
type described in either of the preceding clauses (i) or (ii), may directly or
through other assignees and/or pledgees, assign or pledge such rights to a
Person, which may include a trustee acting on behalf of holders of debt
instruments (any such Person or any such Lender, an "Advance Financing
Person"), and/or (2) an Advance Financing Person agrees to fund all the
Advances and/or Servicing Advances required to be made by the Servicer
pursuant to this Agreement. No consent of the Trustee, Certificateholders or
any other party shall be required before the Servicer may enter into an
Advance Facility nor shall the Trustee or the Certificateholders be a third
party beneficiary of any obligation of an Advance Financing Person to the
Servicer. Notwithstanding the existence of any Advance Facility under which an
Advance Financing Person agrees to fund Advances and/or Servicing Advances,
(A) the Servicer (i) shall remain obligated pursuant to this Agreement to make
Advances and/or Servicing Advances pursuant to and as required by this
Agreement and (ii) shall not be relieved of such obligations by virtue of such
Advance Facility and (B) neither the Advance Financing Person nor any
Servicer's Assignee (as hereinafter defined) shall have any right to proceed
against or otherwise contact any Mortgagor for the purpose of collecting any
payment that may be due with respect to any related Mortgage Loan or enforcing
any covenant of such Mortgagor under the related Mortgage Loan documents.

          (b) If the Servicer enters into an Advance Facility, the Servicer
and the related Advance Financing Person shall deliver to the Trustee at the
address set forth in Section 11.05 hereof a written notice (an "Advance
Facility Notice"), stating (a) the identity of the Advance Financing Person
and (b) the identity of the Person (the "Servicer's Assignee") that will,
subject to Section 3.30(c) hereof, have the right to make withdrawals from the
Collection Account pursuant to Section 3.05 hereof to reimburse previously
unreimbursed Advances and/or

                                      84
<PAGE>

Servicing Advances ("Advance Reimbursement Amounts"). Advance Reimbursement
Amounts (i) shall consist solely of amounts in respect of Advances and/or
Servicing Advances for which the Servicer would be permitted to reimburse
itself in accordance with Section 3.05 hereof, assuming the Servicer had made
the related Advance(s) and/or Servicing Advance(s) and (ii) shall not consist
of amounts payable to a successor Servicer in accordance with Section 3.05
hereof to the extent permitted under Section 3.30(e) below.

          (c) Notwithstanding the existence of an Advance Facility, the
Servicer, on behalf of the Advance Financing Person, shall be entitled to
receive reimbursements of Advances and/or Servicing Advances in accordance
with Section 3.05 hereof, which entitlement may be terminated by the Advance
Financing Person pursuant to a written notice to the Trustee in the manner set
forth in Section 11.05 hereof. Upon receipt of such written notice, the
Servicer shall no longer be entitled to receive reimbursement for any Advance
Reimbursement Amounts and the Servicer's Assignee shall immediately have the
right to receive from the Collection Account all Advance Reimbursement
Amounts. Notwithstanding the foregoing, and for the avoidance of doubt, (i)
the Servicer and/or the Servicer's Assignee shall only be entitled to
reimbursement of Advance Reimbursement Amounts hereunder pursuant to Section
3.05 of this Agreement and shall not otherwise be entitled to make withdrawals
of, or receive, Advance Reimbursement Amounts that shall be deposited in the
Distribution Account pursuant to Section 3.04(b) hereof, and (ii) none of the
Trustee or the Certificateholders shall have any right to, or otherwise be
entitled to, receive any Advance Reimbursement Amounts to which the Servicer
or Servicer's Assignee, as applicable, shall be entitled pursuant to Section
3.05 hereof. An Advance Facility may be terminated by the joint written
direction of the Servicer and the related Advance Financing Person. Written
notice of such termination shall be delivered to the Trustee in the manner set
forth in Section 11.05 hereof. The Trustee shall have no duty or liability
with respect to the calculation of any Advance Reimbursement Amount and shall
be entitled to rely without independent investigation on the Advance Facility
Notice and on such Servicer's report of the amount of Advance Reimbursement
Amounts and Servicing Advance Reimbursement Amounts that were included in the
remittance from such Servicer to the Trustee pursuant to Section 4.07. Such
Servicer shall maintain and provide to any successor Servicer a detailed
accounting on a loan-by-loan basis as to amounts advanced by, pledged or
assigned to, and reimbursed to any Advance Financing Person. The successor
Servicer shall be entitled to rely on any such information provided by the
predecessor Servicer, and the successor Servicer shall not be liable for any
errors in such information.

          (d) [Reserved].

          (e) As between a predecessor Servicer and its Advance Financing
Person, on the one hand, and a successor Servicer and its Advance Financing
Person, if any, on the other hand, Advance Reimbursement Amounts on a
loan-by-loan basis with respect to each Mortgage Loan as to which a Advance
and/or Servicing Advance shall have been made and be outstanding shall be
allocated on a "first-in, first out" basis. In the event the Servicer's
Assignee shall have received some or all of an Advance Reimbursement Amount
related to Advances and/or Servicing Advances that were made by a Person other
than such predecessor Servicer or its related Advance Financing Person in
error, then such Servicer's Assignee shall be required to remit any portion of
such Advance Reimbursement Amount to each Person entitled to such portion of
such Advance Reimbursement Amount. Without limiting the generality of the

                                      85
<PAGE>

foregoing, the Servicer shall remain entitled to be reimbursed by the Advance
Financing Person for all Advances and/or Servicing Advances funded by the
Servicer to the extent the related Advance Reimbursement Amounts have not been
assigned or pledged to such Advance Financing Person or Servicer's Assignee.

          (f) For purposes of any certification of a Servicing Officer of the
Servicer made pursuant to Section 4.07(d), any Nonrecoverable Advance referred
to therein may have been made by the Servicer or any predecessor Servicer. In
making its determination that any Advance or Servicing Advance theretofore
made has become a Nonrecoverable Advance, the Servicer shall apply the same
criteria in making such determination regardless of whether such Advance or
Servicing Advance shall have been made by the Servicer or any predecessor
Servicer.

          (g) The Trustee shall not, as a result of the existence of any
Advance Facility, have any additional responsibility to track or monitor
Advance Reimbursement Amounts or any Advance Facility, and, except as
expressly provided in Section 3.30(c) above, is not and shall not be obligated
to make any payment with respect to any Advance Reimbursement Amount. The
Servicer hereby indemnifies the Trustee, the Trust Fund and any successor
Servicer, as applicable, from and against any claims, losses, liabilities or
damages resulting from any claim by the related Advancing Person, except to
the extent that such claim, loss, liability or damage resulted from or arose
out of negligence, recklessness or willful misconduct on the part of the
Trustee or the successor Servicer, or failure by the successor Servicer or the
Trustee to remit funds as required by this Agreement or the commission of an
act or omission to act by the successor Servicer or the Trustee, and the
passage of any applicable cure or grace period, such that a Servicer Event of
Termination under this Agreement occurs or such entity is subject to
termination for cause under this Agreement.

          With respect to any distributions to be made on the Class B-2

applicable, and then, on the related Class of Certificates.

references above to the Certificate Principal Balance of any Class of
Certificates shall be to the Certificate Principal Balance of such Class

Principal Balance of the largest Mortgage Loan as of the date of determination
and (iii) an amount equal to the current Principal Balances of the Mortgage
Loans in the largest zip-code concentration in the State of California as of
the date of determination, such excess losses will be allocated among all the
outstanding Classes of Certificates, including the Class B-2 Interest, the
Class B-3 Interest, the Class B-4 Interest and the Class X/N Interest, PRO
RATA, based on their respective Certificate Principal Balances or Notional
Amount, as applicable.

          (c) On each Distribution Date, the Trustee shall forward to the
Residual Certificateholders a copy of the reports forwarded to the Regular

          Section 4.07 Remittance Reports; Advances.

          (a) On the second Business Day following each Determination Date but
in no event less than four Business Days prior to the related Distribution
Date, the Servicer shall deliver to the Trustee by telecopy (or by such other
means as the Servicer and the Trustee may agree from time to time) a
Remittance Report with respect to the related Distribution Date. On the same
date, the Servicer shall forward to the Trustee by overnight mail a computer
readable magnetic tape or diskette or in such other medium as may be agreed
between the Servicer and the Trustee containing the information set forth in
such Remittance Report with respect to the related Distribution Date. Not
later than the close of business New York time on the Servicer Remittance
Date, the Servicer shall deliver or cause to be delivered to the Trustee in
addition to the information provided on the Remittance Report, such other
information reasonably available to it with respect to the Mortgage Loans as
the Trustee may reasonably request or order in order for the Trustee to
perform the calculations necessary to make the distributions contemplated by
Section 4.01, 4.02 and 4.03 and to prepare the statements to
Certificateholders contemplated by Section 4.06. The Trustee shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Servicer.

          (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.07(d), (i) the aggregate
amount of Monthly Payments (net of the related Servicing Fee and other than
the portion of the Monthly Payment representing principal on any second lien
Mortgage Loan), due during the related Collection Period in respect

                                      96
<PAGE>

of the Actuarial Mortgage Loans, which Monthly Payments were delinquent on a
contractual basis 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 only the interest portion of
the Monthly Payments (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 deposited in the Collection Account pursuant
to Section 3.13 for distribution on such Distribution Date. For purposes of
the preceding sentence, the Monthly Payment on each Balloon Mortgage Loan with
a delinquent Balloon Payment is equal to the assumed monthly payment that
would have been due on the related Due Date based on the original principal
amortization schedule for the such Balloon Mortgage Loan. The Servicer shall
not be obligated to make any Advance with respect to Simple Interest Mortgage
Loans.

          On or before the close of business New York time on the Servicer
Remittance Date, the Servicer shall remit in immediately available funds to
the Trustee for deposit in the Distribution Account an amount equal to the
aggregate amount of Advances, if any, to be made in respect of the Mortgage
Loans and REO Properties for the related Distribution Date either (i) from its
own funds or (ii) from the Collection Account, to the extent of funds held
therein for future distribution (in which case it will cause to be made an
appropriate entry in the records of the Collection Account that amounts held
for future distribution have been, as permitted by this Section 4.07, used by
the Servicer in discharge of any such Advance) or (iii) in the form of any
combination of (i) and (ii) aggregating the total amount of Advances to be
made by the Servicer with respect to the Mortgage Loans and REO Properties. In
addition, the Servicer shall have the right to reimburse itself for any
Advances previously made from the Collection Account, to the extent of funds
held therein for future distribution. Any amounts held for future distribution
and so used shall be appropriately reflected in the Servicer's records and
replaced by the Servicer by deposit in the Collection Account on or before any
future 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 Servicer Remittance Date) shall be less than the total amount that would
be distributed to the Classes of Certificateholders pursuant to Section 4.01
and 4.02 on such Distribution Date if such amounts held for future
distributions had not been so used to make Advances. The Trustee will provide
notice to the Servicer by telecopy by the close of business on any Servicer
Remittance Date in the event that the amount remitted by the Servicer to the
Trustee on such date is less than the Advances required to be made by the
Servicer for the related Distribution Date, as set forth in the related
Remittance Report.

          (c) The obligation of the 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 the earlier of such time as such Mortgage Loan is paid in full
by the Mortgagor or disposed of by the Trust, or until the recovery of all
Liquidation Proceeds thereon.

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

                                      97
<PAGE>

Nonrecoverable Advance, shall be evidenced by an Officers' Certificate of the
Servicer delivered to the Depositor and the Trustee.

                               THE CERTIFICATES

          Section 5.01 The Certificates.

          Each of the Class A Certificates, the Mezzanine Certificates, the
Class N Certificates, the Class X Certificates and the Residual Certificates
shall be substantially in the forms annexed hereto as exhibits, and shall, on
original issue, be executed by the Trustee and authenticated and delivered by
the Certificate Registrar to or upon the receipt of a Written Order to
Authenticate from the Depositor concurrently with the sale and assignment to
the Trustee of the Trust Fund. Each Class of the Class A Certificates and the
Mezzanine Certificates shall be initially evidenced by one or more
Certificates representing a Percentage Interest with a minimum dollar (or
notional amount) denomination of $25,000 and integral multiples of $1 in
excess thereof. The Class N, Class X and Residual Certificates are issuable
only in minimum Percentage Interests of 10%.

          The Certificates shall be executed on behalf of the Trust by manual
or facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who
were, at the time when such signatures were affixed, authorized to sign on
behalf of the Trustee shall bind the Trust, notwithstanding that such
individuals or any of them have ceased to be so authorized prior to the
authentication and delivery of such Certificates or did not hold such offices
at the date of such Certificate. No Certificate shall be entitled to any
benefit under this Agreement or be valid for any purpose, unless such
Certificate shall have been manually authenticated by the Certificate
Registrar substantially in the form provided for herein, and such
authentication upon any Certificate 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.
Subject to Section 5.02(c), the Class A Certificates and the Mezzanine
Certificates shall be Book-Entry Certificates. The Class N, Class X and
Residual Certificates shall not be Book-Entry Certificates but shall be issued
in fully registered certificate form.

          Section 5.02 Registration of Transfer and Exchange of Certificates.

          (a) The Certificate Registrar shall cause to be kept at the
Corporate Trust Office of the Trustee a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Certificate Registrar
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 Trustee as
Certificate Registrar shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall
apply to the

Certificate Registrar appointed in accordance with this Section 5.02(a) may at
any time resign by giving at least 30 days' advance written notice of
resignation to the Trustee, the Servicer and the Depositor, such resignation
to become effective upon appointment of a successor Certificate Registrar.

          Upon surrender for registration of transfer of any Certificate at
any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of a Residual
Certificate, upon satisfaction of the conditions set forth below, the Trustee
on behalf of the Trust shall execute and the Certificate Registrar shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same aggregate Percentage
Interest.

          At the option of the Certificateholders, Certificates may be
exchanged for other Certificates in authorized denominations and the same
aggregate Percentage Interests, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute on behalf of the Trust and
the Certificate Registrar shall authenticate and deliver the Certificates
which the Certificateholder making the exchange is entitled to receive. Every
Certificate presented or surrendered for registration of transfer or exchange
shall (if so required by the Trustee or the Certificate Registrar) be duly
endorsed by, or be accompanied by a written instrument of transfer
satisfactory to the Trustee and the Certificate Registrar duly executed by,
the Holder thereof or his attorney duly authorized in writing.

          (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository, the initial Depository, by, or on behalf of, the Depositor; or
to, and deposited with the Certificate Custodian, on behalf of the Depository,
if directed to do so pursuant to instructions from the Depository. Except as
provided in paragraph (c) below, the Book-Entry Certificates shall at all
times remain registered in the name of the Depository or its nominee and at
all times: (i) registration of such Certificates may not be transferred by the
Trustee except to another Depository; (ii) the Depository shall maintain
book-entry records with respect to the Certificate Owners and with respect to
ownership and transfers of such Certificates; (iii) ownership and transfers of
registration of such Certificates on the books of the Depository shall be
governed by applicable rules established by the Depository; (iv) the
Depository may collect its usual and customary fees, charges and expenses from
its Depository Participants; (v) the Trustee shall for all purposes deal with
the Depository as representative of the Certificate Owners of the Certificates
for purposes of exercising the rights of Holders under this Agreement, and
requests and directions for and votes of such representative shall not be
deemed to be inconsistent if they are made with respect to different
Certificate Owners; (vi) the Trustee may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its
Depository Participants and furnished by the Depository Participants with
respect to indirect participating firms and Persons shown on the books of such
indirect participating firms as direct or indirect Certificate Owners; and
(vii) the direct participants of the Depository shall have no rights under
this Agreement under or with respect to any of the Certificates held on their
behalf by the Depository, and the Depository may be treated by the Trustee and
its agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

          All transfers by Certificate Owners of Book-Entry Certificates shall
be made in accordance with the procedures established by the Depository
Participant or brokerage firm representing such Certificate Owners. Each
Depository Participant shall only transfer Book Entry Certificates of
Certificate Owners that it represents or of brokerage firms for which it acts
as agent in accordance with the Depository's normal procedures. The parties
hereto are hereby authorized to execute a Letter of Representations with the
Depository or take such other action as may be necessary or desirable to
register a Book-Entry Certificate to the Depository.

          (c) If (i)(x) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and (y) the Trustee or the Depositor is
unable to locate a qualified successor or (ii) after the occurrence of a
Servicer Event of Termination, the Certificate Owners of each Class of
Book-Entry Certificates representing Percentage Interests of such Classes
aggregating not less than 51% advises the Trustee and Depository through the
Financial Intermediaries and the Depository Participants in writing that the
continuation of a book-entry system through the Depository to the exclusion of
definitive, fully registered certificates (the "Definitive Certificates") to
Certificate Owners is no longer in the best interests of the Certificate
Owners. Upon surrender to the Certificate Registrar of the Book-Entry
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Trustee shall, at the Depositor's
expense, in the case of (ii) above, or the Seller's expense, in the case of
(i) and (iii) above, execute on behalf of the Trust and the Certificate
Registrar shall authenticate the Definitive Certificates. Neither the
Depositor nor the Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying
on, such instructions. Upon the issuance of Definitive Certificates, the
Trustee, the Certificate Registrar, the Servicer, any Paying Agent and the
Depositor shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder.

          (d) Except with respect to the initial transfer of the Private
Certificates by the Depositor, no transfer, sale, pledge or other disposition
of any Private Certificate shall be made unless such disposition is exempt
from the registration requirements of the Securities Act of 1933, as amended
(the "1933 Act"), and any applicable state securities laws or is made in
accordance with the 1933 Act and laws. In the event of any such transfer, (i)
unless such transfer is made in reliance upon Rule 144A (as evidenced by the
investment letter delivered to the Certificate Registrar, in substantially the
form attached hereto as Exhibit J-2) under the 1933 Act, the Certificate
Registrar and the Depositor shall require a written Opinion of Counsel (which
may be in-house counsel) acceptable to and in form and substance reasonably
satisfactory to the Certificate Registrar and the Depositor that such transfer
may be made pursuant to an exemption, describing the applicable exemption and
the basis therefor, from the 1933 Act or is being made pursuant to the 1933
Act, which Opinion of Counsel shall not be an expense of the Certificate
Registrar or the Depositor or (ii) the Certificate Registrar shall require the
transferor to execute a transferor certificate (in substantially the form
attached hereto as Exhibit L) and the transferee to execute an investment
letter (in substantially the form attached hereto as Exhibit J-1) acceptable
to and in form and substance reasonably satisfactory to the Depositor and the
Certificate Registrar certifying to the Depositor and the Certificate
Registrar the facts surrounding such transfer, which investment letter shall
not be an expense of the Certificate Registrar or the Depositor. The Holder of
a Private Certificate desiring to effect such transfer shall, and does hereby
agree to, indemnify the Certificate Registrar and the Depositor against any
liability that

                                     100
<PAGE>

may result if the transfer is not so exempt or is not made in accordance with
such federal and state laws.

          No transfer of an ERISA Restricted Certificate shall be made unless
the Certificate Registrar shall have received either (i) a representation from
the transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Certificate Registrar and the Depositor, (such requirement
is satisfied only by the Certificate Registrar's receipt of a representation
letter from the transferee substantially in the form of Exhibit I hereto, as
appropriate), to the effect that such transferee is not an employee benefit
plan or arrangement subject to Section 406 of ERISA or a plan subject to
Section 4975 of the Code, nor a person acting on behalf of any such plan or
arrangement nor using the assets of any such plan or arrangement to effect
such transfer or (ii) (except in the case of a Residual, Class X or Class N
Certificate) if the purchaser is an insurance company, a representation that
the purchaser is an insurance company which is purchasing such Certificates
with funds contained in an "insurance company general account" (as such term
is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60
("PTCE 95-60") and that the purchase and holding of such Certificates are
covered under Sections I and III of PTCE 95-60 or (iii) (except in the case of
a Residual Certificate) in the case of any such ERISA Restricted Certificate
presented for registration in the name of an employee benefit plan subject to
ERISA or a plan or arrangement subject to Section 4975 of the Code (or
comparable provisions of any subsequent enactments), or a trustee of any such
plan or any other person acting on behalf of any such plan or arrangement or
using such plan's or arrangement's assets, an Opinion of Counsel satisfactory
to the Certificate Registrar, to the effect that the purchase and holding of
such ERISA Restricted Certificate will not result in a non-exempt prohibited
transaction under ERISA and the Code and will not subject the Servicer, the
Trustee or the Certificate Registrar to any obligation in addition to those
expressly undertaken in this Agreement or to any liability. For purposes of
the preceding sentence, the representation in (i) or (ii) shall be deemed to
have been made to the Certificate Registrar by the acceptance by a Certificate
Owner of the beneficial interest in any such Class of ERISA Restricted
Certificates, unless the Certificate Registrar shall have received from the
transferee an alternative representation acceptable in form and substance to
the Depositor. Notwithstanding anything else to the contrary herein, any
purported transfer of an ERISA Restricted Certificate to or on behalf of an
employee benefit plan subject to ERISA in violation of this paragraph as
described above shall be void and of no effect.

          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 appointed the Depositor or its designee as its
attorney-in-fact to negotiate the terms of any mandatory sale under clause (v)
below and to execute all instruments of transfer and to do all other things
necessary in connection with any such sale, and the rights of each Person
acquiring any Ownership Interest in a Residual Certificate are expressly
subject to the following provisions:

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

                                     101
<PAGE>

          (ii) No Person shall acquire an Ownership Interest in a Residual
     Certificate unless such Ownership Interest is a PRO RATA undivided
     interest.

          (iii) In connection with any proposed transfer of any Ownership
     Interest in a Residual Certificate, the Certificate Registrar shall as a
     condition to registration of the transfer, require delivery to it, in
     form and substance satisfactory to it, of each of the following:

               A. an affidavit in the form of Exhibit K hereto from the
          proposed transferee to the effect that, among other things, such
          transferee is a Permitted Transferee and 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 who is not a Permitted Transferee; and

               B. a covenant of the proposed transferee to the effect that the
          proposed transferee agrees to be bound by and to abide by the
          transfer restrictions applicable to the Residual Certificates.

          (iv) Any attempted or purported transfer of any Ownership Interest
     in a Residual Certificate in violation of the provisions of this Section
     shall be absolutely null and void and shall vest no rights in the
     purported transferee. If any purported transferee shall, in violation of
     the provisions of this Section, become a Holder of a Residual
     Certificate, then the prior Holder of such Residual Certificate that is a
     Permitted Transferee shall, upon discovery that the registration of
     transfer of such Residual Certificate was not in fact permitted by this
     Section, be restored to all rights as Holder thereof retroactive to the
     date of registration of 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 or for making any distributions due on such
     Residual Certificate to the Holder thereof or taking any other action
     with respect to such Holder under the provisions of this Agreement so
     long as the Certificate Registrar received the documents specified in
     clause (iii). The Trustee shall be entitled to recover from any Holder of
     a Residual Certificate that was in fact not a Permitted Transferee at the
     time such distributions were made all distributions made on such Residual
     Certificate. Any such distributions so recovered by the Trustee shall be
     distributed and delivered by the Trustee to the prior Holder of such
     Residual Certificate that is a Permitted Transferee.

          (v) If any Person other than a Permitted Transferee acquires any
     Ownership Interest in a Residual Certificate in violation of the
     restrictions in this Section, then the Certificate Registrar shall have
     the right but not the obligation, without notice to the Holder of such
     Residual Certificate or any other Person having an Ownership Interest
     therein, to notify the Depositor to arrange for the sale of such Residual
     Certificate. The proceeds of such sale, net of commissions (which may
     include commissions payable to the Depositor or its affiliates in
     connection with such sale), expenses and taxes due, if any, will be
     remitted by the Trustee to the previous Holder of such Residual
     Certificate that is a Permitted Transferee, except that in the event that
     the Trustee determines that the Holder of such Residual Certificate may
     be liable for any amount due under this Section

                                     102
<PAGE>

     or any other provisions of this Agreement, the Trustee may withhold a
     corresponding amount from such remittance as security for such claim. The
     terms and conditions of any sale under this clause (v) shall be
     determined in the sole discretion of the Trustee and it shall not be
     liable to any Person having an Ownership Interest in a Residual
     Certificate as a result of its exercise of such discretion.

          (vi) If any Person other than a Permitted Transferee acquires any
     Ownership Interest in a Residual Certificate in violation of the
     restrictions in this Section, then the Trustee will provide to the
     Internal Revenue Service, and to the persons specified in Sections
     860E(e)(3) and (6) of the Code, information needed to compute the tax
     imposed under Section 860E(e)(5) of the Code on transfers of residual
     interests to disqualified organizations. The Trustee shall be entitled to
     reasonable compensation for providing such information from the person to
     whom it is provided.

          The foregoing provisions of this Section shall cease to apply to
transfers occurring on or after the date on which there shall have been
delivered to the Certificate Registrar, in form and substance satisfactory to
the Certificate Registrar, (i) written notification from each Rating Agency
that the removal of the restrictions on Transfer set forth in this Section
will not cause such Rating Agency to downgrade its rating of the Certificates
and (ii) an Opinion of Counsel to the effect that such removal will not cause
any REMIC hereunder to fail to qualify as a REMIC.

          (e) No service charge shall be made for any registration of transfer
or exchange of Certificates of any Class, but the Certificate Registrar 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.

          All Certificates surrendered for registration of transfer or
exchange shall be cancelled by the Certificate Registrar and disposed of
pursuant to its standard procedures.

          The beneficial ownership of the Class N Certificates and the Class X
Certificates shall not be transferred to a person other than a United States
Person (a "non-U.S. Person") unless such beneficial ownership is transferred
to a non-United States Person who will at all times be a Proportionate Holder.
Neither the Class N nor the Class X Certificates shall be pledged or used as
collateral for any other obligation if it would cause any portion of the Trust
Fund to be treated as a taxable mortgage pool under section 7707(i) of the
Code. These restrictions on transfers of Class X and Class N Certificates set
forth in this Section 5.02 shall cease to apply (and the applicable portions
of any legend on a Class X or Class N Certificate may be deleted) with respect
to transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Seller or
the Servicer to the effect that the elimination of such restrictions will not
cause the Trust Fund to fail to qualify as a REMIC at any time that the
Certificates are outstanding or result in the imposition of any tax or tax
reporting obligation on the Trust Fund, a Certificateholder or another Person.

          Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

          If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction
of the destruction, loss or theft of any

                                     103
<PAGE>

Certificate and (ii) there is delivered to the Trustee, the Depositor 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 notice to the Trustee or
the Certificate Registrar that such Certificate has been acquired by a bona
fide purchaser, the Trustee shall execute on behalf of the Trust, and the
Certificate Registrar shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like tenor and Percentage Interest. Upon the issuance of any
new Certificate under this Section, the Trustee or the Certificate Registrar
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee and the Certificate
Registrar) in connection therewith. Any duplicate Certificate issued pursuant
to this Section, shall constitute complete and indefeasible evidence of
ownership in the Trust, 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 Servicer, the Depositor, the Trustee, the Certificate Registrar,
any Paying Agent and any agent of the Servicer, the Depositor, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, 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 Section 4.02 and for all other purposes whatsoever, and none of the
Servicer, the Trust, the Trustee nor any agent of any of them shall be
affected by notice to the contrary.

          Section 5.05 Appointment of Paying Agent.

          The Paying Agent shall make distributions to Certificateholders from
the Distribution Account pursuant to Section 4.01 and Section 4.02 and shall
report the amounts of such distributions to the Trustee. The duties of the
Paying Agent may include the obligation (i) to withdraw funds from the
Collection Account pursuant to Section 3.05 and for the purpose of making the
distributions referred to above and (ii) to distribute statements and provide
information to Certificateholders as required hereunder. The Paying Agent
hereunder shall at all times be an entity duly incorporated and validly
existing under the laws of the United States of America or any state thereof,
authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by federal or state authorities. The Paying Agent
shall initially be the Trustee. The Trustee may appoint a successor to act as
Paying Agent, which appointment shall be reasonably satisfactory to the
Depositor and the Rating Agencies. The Trustee as Paying Agent shall be
subject to the same standards of care, limitations on liability and rights to
indemnity as the Trustee, and the provisions of Sections 8.01, 8.02, 8.03,
8.04, 8.05, 8.14, 8.15 and 8.16 shall apply to the Paying Agent to the same
extent as they apply to the Trustee. Any Paying Agent appointed in accordance
with this Section 5.02(a) may at any time resign by giving at least 30 days'
advance written notice of resignation to the Trustee, the Servicer and the
Depositor, such resignation to become effective upon appointment of a
successor Paying Agent.

                  THE SELLER, THE SERVICER AND THE DEPOSITOR

          Section 6.01 Liability of the Seller, the Servicer and the
Depositor.

          The Seller and the Servicer shall be liable in accordance herewith
only to the extent of the obligations specifically imposed upon and undertaken
by the Seller or Servicer, as the case may be, herein. The Depositor shall be
liable in accordance herewith only to the extent of the obligations
specifically imposed upon and undertaken by the Depositor.

          Section 6.02 Merger or Consolidation of, or Assumption of the
                       Obligations of, the Seller, the Servicer or the
                       Depositor.

          Any entity into which the Seller, the Servicer or the Depositor may
be merged or consolidated, or any entity resulting from any merger, conversion
or consolidation to which the Seller, the Servicer or the Depositor shall be a
party, or any corporation succeeding to the business of the Seller, the
Servicer or the Depositor, shall be the successor of the Seller, the Servicer
or the Depositor, 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 Servicer shall satisfy all the requirements of Section 7.02
with respect to the qualifications of a successor Servicer.

          Section 6.03 Limitation on Liability of the Servicer and Others.

          Neither the Servicer, the Depositor nor any of the directors or
officers or employees or agents of the Servicer or the Depositor shall be
under any liability to the Trust or the Certificateholders for any action
taken or for refraining from the taking of any action by the Servicer in good
faith pursuant to this Agreement, or for errors in judgment; PROVIDED,
HOWEVER, that this provision shall not protect the Servicer, the Depositor or
any such Person against any liability which would otherwise be imposed by
reason of its willful misfeasance, bad faith or gross negligence in the
performance of duties of the Servicer or the Depositor or by reason of its
reckless disregard of its obligations and duties of the Servicer or the
Depositor hereunder; PROVIDED, FURTHER, that this provision shall not be
construed to entitle the Servicer to indemnity in the event that amounts
advanced by the Servicer to retire any senior lien exceed Liquidation Proceeds
(in excess of related liquidation expenses) realized with respect to the
related Mortgage Loan. The Servicer, the Depositor and any director or officer
or employee or agent of the Servicer or the Depositor may rely in good faith
on any document of any kind PRIMA FACIE properly executed and submitted by any
Person respecting any matters arising hereunder. The Servicer, the Depositor
and any director or officer or employee or agent of the Servicer or the
Depositor shall be indemnified by the Trust and held harmless 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 incurred by reason of its willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of its reckless
disregard of obligations and duties hereunder. The Servicer or the Depositor
may undertake any such action which it may deem necessary or desirable in
respect of this Agreement, and the rights and duties of the parties hereto and
the interests of the

                                     105
<PAGE>

Certificateholders hereunder. In such event, the reasonable legal expenses and
costs of such action and any liability resulting therefrom shall be expenses,
costs and liabilities of the Trust and the Servicer or the Depositor shall be
entitled to pay such expenses from the proceeds of the Trust or to be
reimbursed therefor pursuant to Section 3.05 upon presentation to the Trustee
of documentation of such expenses, costs and liabilities. The Servicer's right
to indemnity or reimbursement pursuant to this Section shall survive any
resignation or termination of the Servicer pursuant to Section 6.04 or 7.01
with respect to any losses, expenses, costs or liabilities arising prior to
such resignation or termination (or arising from events that occurred prior to
such resignation or termination). This paragraph shall apply to the Servicer
and the Depositor solely in their capacities as Servicer and Depositor
hereunder and in no other capacities.

          Section 6.04 Servicer Not to Resign.

          Subject to the provisions of Section 7.01 and Section 6.02, the
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or
duties hereunder are no longer permissible under applicable law or are in
material conflict by reason of applicable law with any other activities
carried on by it or its subsidiaries or Affiliates, the other activities of
the Servicer so causing such a conflict being of a type and nature carried on
by the Servicer or its subsidiaries or Affiliates at the date of this
Agreement or (ii) upon satisfaction of the following conditions: (a) the
Servicer has proposed a successor servicer to the Trustee in writing and such
proposed successor servicer is reasonably acceptable to the Trustee; and (b)
each Rating Agency shall have delivered a letter to the Trustee prior to the
appointment of the successor servicer stating that the proposed appointment of
such successor servicer as Servicer hereunder will not result in the reduction
or withdrawal of the then current rating of the Regular Certificates or the
ratings that are in effect; PROVIDED, HOWEVER, that no such resignation by the
Servicer shall become effective until such successor servicer or, in the case
of (i) above, the Trustee shall have assumed the Servicer's responsibilities
and obligations hereunder or the Trustee shall have designated a successor
servicer in accordance with Section 7.02. Any such resignation shall not
relieve the Servicer of responsibility for any of the obligations specified in
Sections 7.01 and 7.02 as obligations that survive the resignation or
termination of the Servicer. Any such determination permitting the resignation
of the Servicer pursuant to clause (i) above shall be evidenced by an Opinion
of Counsel to such effect delivered to the Trustee. Any such determination
permitting the resignation of the Servicer shall be evidenced by an Opinion of
Counsel to such effect delivered to the Trustee.

          The Trustee and the Depositor hereby specifically (i) consent to the
pledge and assignment by the Servicer of all the Servicer's right, title and
interest in, to and under this Agreement to the Servicing Rights Pledgee, for
the benefit of certain lenders, and (ii) provided that no Servicer Event of
Termination exists, agree that upon delivery to the Trustee by the Servicing
Rights Pledgee of a letter signed by the Servicer whereunder the Servicer
shall resign as Servicer under this Agreement, the Trustee shall appoint the
Servicing Rights Pledgee or its designee as successor Servicer, provided that
at the time of such appointment, the Servicing Rights Pledgee or such designee
meets the requirements of a successor Servicer pursuant to Section 7.02(a) and
agrees to be subject to the terms of this Agreement. If, pursuant to any
provision hereof, the duties of the Servicer are transferred to a successor,
the entire amount of the

                                     106
<PAGE>

Servicing Fee and other compensation payable to the Servicer pursuant hereto
shall thereafter be payable to such successor.

          Section 6.05 Delegation of Duties.

          In the ordinary course of business, the Servicer at any time may
delegate any of its duties hereunder to any Person, including any of its
Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those set forth in Section 3.01. Such delegation shall not
relieve the Servicer of its liabilities and responsibilities with respect to
such duties and shall not constitute a resignation within the meaning of
Section 6.04. The Servicer shall provide the Trustee and the Rating Agencies
with 60 days prior written notice prior to the delegation of any of its duties
to any Person other than any of the Servicer's Affiliates or their respective
successors and assigns.

          Section 7.01 Servicer Events of Termination.

          (a) If any one of the following events ("Servicer Events of
Termination") shall occur and be continuing:

          (i) (A) The failure by the Servicer to make any Advance; or (B) any
     other failure by the Servicer to deposit in the Collection Account or
     Distribution Account any deposit required to be made under the terms of
     this Agreement which continues unremedied for a period of one Business
     Day after the date upon which written notice of such failure shall have
     been given to the Servicer by the Trustee or by any Holder of a Regular
     Certificate evidencing at least 25% of the Voting Rights; or

          (ii) The failure by the Servicer to make any required Servicing
     Advance which failure continues unremedied for a period of 30 days, or
     the failure by the Servicer duly to observe or perform, in any material
     respect, any other covenants, obligations or agreements of the Servicer
     as set forth in this Agreement, which failure continues unremedied for a
     period of 30 days, after the date (A) on which written notice of such
     failure, requiring the same to be remedied, shall have been given to the
     Servicer by the Trustee or by any Holder of a Regular Certificate
     evidencing at least 25% of the Voting Rights or (B) actual knowledge of
     such failure by a Servicing Officer of the Servicer; or

          (iii) The entry against the Servicer of a decree or order by a court
     or agency or supervisory authority having jurisdiction in the premises
     for the appointment of a trustee, conservator, receiver or liquidator in
     any insolvency, conservatorship, receivership, readjustment of debt,
     marshalling of assets and liabilities or similar proceedings, or for the
     winding up or liquidation of its affairs, and the continuance of any such
     decree or order unstayed and in effect for a period of 60 days; or

          (iv) The Servicer shall voluntarily go into liquidation, consent to

<PAGE>

     insolvency, readjustment of debt, marshalling of assets and liabilities
     or similar proceedings of or relating to the Servicer or of or relating
     to all or substantially all of its property; or a decree or order of a

     premises for the appointment of a conservator, receiver, liquidator or
     similar person in any insolvency, readjustment of debt, marshalling of
     assets and liabilities or similar proceedings, or for the winding-up or
     liquidation of its affairs, shall have been entered against the Servicer

     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

          (v) The aggregate amount of cumulative Realized Losses incurred
     since the Cut- off Date through the last day of the related Collection

          (b) Then, and in each and every such case, so long as a Servicer
Event of Termination shall not have been remedied within the applicable grace
period, (x) with respect solely to clause (i)(A) above, if such Advance is not
made by 2:00 P.M., New York time, on the Business Day immediately following
the Servicer Remittance Date, the Trustee may terminate all of the rights and
obligations of the Servicer under this Agreement and the Trustee, or a
successor servicer appointed in accordance with Section 7.02, shall
immediately make such Advance and assume, pursuant to Section 7.02, the duties
of a successor Servicer and (y) in the case of (i)(B), (ii), (iii), (iv) and
(v) above, the Trustee shall, at the direction of the Holders of each Class of
Regular Certificates evidencing Percentage Interests aggregating not less than
51%, by notice then given in writing to the Servicer and the Trustee,
terminate all of the rights and obligations of the Servicer as servicer under
this Agreement. Any such notice to the Servicer shall also be given to each
Rating Agency, the Depositor and the Seller. On or after the receipt by the
Servicer and the Trustee of such written notice, all authority and power of
the Servicer under this Agreement, whether with respect to the Certificates 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 to execute and deliver, on behalf of the
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and Related
Documents or otherwise. The Servicer agrees to cooperate with the Trustee (or
the applicable successor Servicer) in effecting the termination of the
responsibilities and rights of the Servicer hereunder, including, without
limitation, the delivery to the successor Servicer of all documents and
records requested by it to enable it to assume the

                                     108

<PAGE>

Servicer's functions under this Agreement within ten Business Days subsequent
to such notice, the transfer within one Business Day subsequent to such notice
to the Trustee (or the applicable successor Servicer) for the administration
by it of all cash amounts that shall at the time be held by the Servicer and
to be deposited by it in the Collection Account, the Distribution Account, any
REO Account or any Escrow Account or that have been deposited by the Servicer
in such accounts or thereafter received by the Servicer with respect to the
Mortgage Loans or any REO Property received by the Servicer. All reasonable
costs and expenses (including attorneys' fees) incurred in connection with
transferring the servicing to the successor Servicer and amending this
Agreement to reflect such succession as Servicer pursuant to this Section
shall be paid by the predecessor Servicer (or if the predecessor Servicer is
the Trustee, the initial Servicer) upon presentation of reasonable
documentation of such costs and expenses.

          Section 7.02 Trustee to Act; Appointment of Successor.

          (a) Within 90 days of the time the Servicer and the Trustee receives
a notice of termination or resignation pursuant to Section 7.01 or 6.04, the
Trustee (or such other successor Servicer as is approved in accordance with
this Agreement) shall be the successor in all respects to the Servicer in its
capacity as 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 placed on the Servicer by the terms and
provisions hereof arising on and after its succession. As compensation
therefor, the Trustee (or such other successor Servicer) shall be entitled to
such compensation as the Servicer would have been entitled to hereunder if no
such notice of termination had been given. Notwithstanding the above, (i) if
the Trustee is unwilling to act as successor Servicer or (ii) if the Trustee
is legally unable so to act, the Trustee shall appoint or petition a court of
competent jurisdiction to appoint, any established housing and home finance
institution, bank or other mortgage loan or home equity loan servicer having a
net worth of not less than $50,000,000 as the successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder; PROVIDED, that the appointment of
any such successor Servicer will not result in the qualification, reduction or
withdrawal of the ratings assigned to the Certificates or the ratings that are
in effect by the Rating Agencies as evidenced by a letter to such effect from
the Rating Agencies. Pending appointment of a successor to the Servicer
hereunder, unless the Trustee is prohibited by law from so acting, the Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the successor shall be entitled to receive
compensation out of payments on Mortgage Loans in an amount equal to the
compensation which the Servicer would otherwise have received pursuant to
Section 3.18 (or such other compensation as the Trustee and such successor
shall agree, not to exceed the Servicing Fee). The successor servicer shall be
entitled to withdraw from the Collection Account all costs and expenses
associated with the transfer of the servicing to the successor servicer. The
appointment of a successor servicer shall not affect any liability of the
predecessor Servicer which may have arisen under this Agreement prior to its
termination as Servicer to pay any deductible under an insurance policy
pursuant to Section 3.12 or to indemnify the parties indicated in Section 3.26
pursuant to the terms thereof, nor shall any successor Servicer be liable for
any acts or omissions of the predecessor Servicer or for any breach by such
Servicer of any of its representations or warranties contained herein or in
any related document or agreement. The Trustee and such successor shall take
such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

                                     109
<PAGE>

          In the event of a Servicer Event of Termination, notwithstanding
anything to the contrary above, the Trustee and the Depositor hereby agree
that upon delivery to the Trustee by the Servicing Rights Pledgee of a letter
signed by the Servicer within ten Business Days of when notification of such
event shall have been provided to the Trustee, whereunder the Servicer shall
resign as Servicer under this Agreement, the Servicing Rights Pledgee or its
designee shall be appointed as successor Servicer (provided that at the time
of such appointment the Servicing Rights Pledgee or such designee meets the
requirements of a successor Servicer set forth above) and the Servicing Rights
Pledgee agrees to be subject to the terms of this Agreement.

          (b) Any successor, including the Trustee, to the Servicer as
servicer shall during the term of its service as servicer continue to service
and administer the Mortgage Loans for the benefit of Certificateholders, and
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and a
Fidelity Bond in respect of its officers, employees and agents to the same
extent as the Servicer is so required pursuant to Section 3.12.

          Section 7.03 Waiver of Defaults.

          The Majority Certificateholders may, on behalf of all
Certificateholders, waive any events permitting removal of the Servicer as
servicer pursuant to this Article VII, PROVIDED, HOWEVER, that the Majority
Certificateholders may not waive a default in making a required distribution
on a Certificate without the consent of the Holder of such Certificate. Upon
any waiver of a past default, such default shall cease to exist and any
Servicer Event of Termination arising therefrom shall be deemed to have been
remedied for every purpose of this Agreement. No such waiver shall extend to
any subsequent or other default or impair any right consequent thereto except
to the extent expressly so waived. Notice of any such waiver shall be given by
the Trustee to the Rating Agencies.

          Section 7.04 Notification to Certificateholders.

          (a) On any termination or appointment of a successor the Servicer
pursuant to this Article VII or Section 6.04, the Trustee shall give prompt
written notice thereof to the Certificateholders at their respective addresses
appearing in the Certificate Register and each Rating Agency.

          (b) No later than 60 days after the occurrence of any event which
constitutes or which, with notice or a lapse of time or both, would constitute
a Servicer Event of Termination for five Business Days after a Responsible
Officer of the Trustee becomes aware of the occurrence of such an event, the
Trustee shall transmit by mail to all Certificateholders notice of such
occurrence unless such default or Servicer Event of Termination shall have
been waived or cured. Such notice shall be given to the Rating Agencies
promptly after any such occurrence.

          Section 7.05 Survivability of Servicer Liabilities.

          Notwithstanding anything herein to the contrary, upon termination of
the Servicer hereunder, any liabilities of the Servicer which accrued prior to
such termination shall survive such termination.

                                 ARTICLE VIII

                                  THE TRUSTEE

          Section 8.01 Duties of Trustee.

          The Trustee, prior to the occurrence of a Servicer Event of
Termination of which a Responsible Officer of the Trustee shall have actual
knowledge and after the curing of all Servicer Events of Termination which may
have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. If a Servicer Event of Termination
has occurred (which has not been cured) of which a Responsible Officer has
actual knowledge, 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.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the Trustee which are specifically required to be furnished
pursuant to any provision of this Agreement, shall examine them to determine
whether they conform to the requirements of this Agreement; PROVIDED, HOWEVER,
that the Trustee shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Servicer, the Seller or the Depositor hereunder.
If any such instrument is found not to conform in any material respect to the
requirements of this Agreement, the Trustee shall notify the
Certificateholders of such instrument in the event that the Trustee, after so
requesting, does not receive a satisfactorily corrected instrument.

          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 Servicer Event of Termination, and
     after the curing of all such Servicer Events of Termination 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 and conforming to the requirements of
     this Agreement;

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

          (iii) the Trustee shall not be 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 Majority

                                     111

<PAGE>

     Certificateholders relating to the time, method and place of conducting
     any proceeding for any remedy available to the Trustee or exercising or
     omitting to exercise any trust or power conferred upon the Trustee under
     this Agreement; and

          (iv) the Trustee shall not be charged with knowledge of any failure
     by the Servicer to comply with the obligations of the Servicer referred
     to in clauses (i) and (ii) of Section 7.01(a) or any Servicer Event of
     Termination unless a Responsible Officer of the Trustee at the applicable
     Corporate Trust Office obtains actual knowledge of such failure or the
     Trustee receives written notice of such failure from the Servicer or the
     Majority Certificateholders. In the absence of such receipt of such
     notice, the Trustee may conclusively assume that there is no Servicer
     Event of Termination.

          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
the Trustee to perform, or be responsible for the manner of performance of,
any of the obligations of the Servicer under this Agreement, except with
respect to the Trustee 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 Servicer in accordance with the terms of this Agreement.

          The Trustee shall not have any duty (A) to see any recording,
filing, or depositing of this Agreement or any agreement referred to herein or
any financing statement or continuation statement evidencing a security
interest, or to see to the maintenance of any such recording or filing or
depositing or to any rerecording, refiling or redepositing of any thereof, (B)
to see to any insurance or (C) to see to the payment or discharge of any tax,
assessment, or other governmental charge or any lien or encumbrance of any
kind owing with respect to, assessed or levied against, any part of the Trust
Fund other than from funds available in the Distribution Account.

          Section 8.02 Certain Matters Affecting the Trustee.

          (a) Except as otherwise provided in Section 8.01:

          (i) the Trustee may request and rely upon, and shall be protected in
     acting or refraining from acting upon, any resolution, Officer's
     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 advice or 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 advice or Opinion of Counsel;

          (iii) the Trustee shall not be under any obligation to exercise any
     of the rights or powers vested in it by this Agreement, or to institute,
     conduct or defend any litigation

                                     112

<PAGE>

     hereunder or in relation hereto, at the request, order or direction of
     the Certificateholders pursuant to the provisions of this Agreement,
     unless such Certificateholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities which may be incurred therein or thereby; the right of the
     Trustee to perform any discretionary act enumerated in this Agreement
     shall not be construed as a duty, and the Trustee shall not be answerable
     for other than its negligence or willful misconduct in the performance of
     any such act;

          (iv) the Trustee shall not be 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 Servicer Event of Termination and
     after the curing of all Servicer Events of Termination 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 documents, unless requested in writing to do so by
     the Majority Certificateholder; 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 the security afforded to it by the terms of this
     Agreement, the Trustee may require reasonable indemnity against such
     cost, expense or liability as a condition to such proceeding. The
     reasonable expense of every such examination shall be paid by the
     Servicer or, if paid by the Trustee, shall be reimbursed by the Servicer
     upon demand. Nothing in this clause (v) shall derogate from the
     obligation of the Servicer to observe any applicable law prohibiting
     disclosure of information regarding the Mortgagors;

          (vi) the Trustee shall not be accountable, shall have any liability
     or make any representation as to any acts or omissions hereunder of the
     Servicer until such time as the Trustee may be required to act as
     Servicer pursuant to Section 7.02;

          (vii) 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 or a custodian and the Trustee shall not be responsible for
     any misconduct or negligence on the part of any such agent, attorney or
     custodian appointed by it with due care; and

          (viii) the right of the Trustee to perform any discretionary act
     enumerated in this Agreement shall not be construed as a duty, and the
     Trustee shall not be answerable for other than its negligence or willful
     misconduct in the performance of such act.

          Section 8.03 Trustee not Liable for Certificates or Mortgage Loans.

          The recitals contained herein and in the Certificates (other than
the authentication of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the Certificates (other than
the signature

                                     113

<PAGE>

of the Trustee and authentication of the Trustee on the Certificates) or of
any Mortgage Loan or Related Document. The Trustee shall not be accountable
for the use or application by the Servicer, or for the use or application of
any funds paid to the Servicer in respect of the Mortgage Loans or deposited
in or withdrawn from the Collection Account by the Servicer. The Trustee shall
not at any time have any responsibility or liability for or with respect to
the legality, validity and enforceability of any Mortgage or any Mortgage
Loan, or the perfection and priority of any Mortgage or the maintenance of any
such perfection and priority, or for or with respect to the sufficiency of the
Trust or its ability to generate the payments to be distributed to
Certificateholders under this Agreement, including, without limitation: the
existence, condition and ownership of any Mortgaged Property; the existence
and enforceability of any hazard insurance thereon (other than if the Trustee
shall assume the duties of the Servicer pursuant to Section 7.02); the
validity of the assignment of any Mortgage Loan to the Trustee or of any
intervening assignment; the completeness of any Mortgage Loan; the performance
or enforcement of any Mortgage Loan (other than if the Trustee shall assume
the duties of the Servicer pursuant to Section 7.02); the compliance by the
Depositor, the Seller or the Servicer with any warranty or representation made
under this Agreement or in any related document or the accuracy of any such
warranty or representation prior to the Trustee's receipt of notice or other
discovery of any non-compliance therewith or any breach thereof; any
investment of monies by or at the direction of the Servicer or any loss
resulting therefrom, it being understood that the Trustee shall remain
responsible for any Trust property that it may hold in its individual
capacity; the acts or omissions of any of the Servicer (other than if the
Trustee shall assume the duties of the Servicer pursuant to Section 7.02), or
any Mortgagor; any action of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02), taken in the name
of the Trustee; the failure of the Servicer to act or perform any duties
required of it as agent of the Trustee hereunder; or any action by the Trustee
taken at the instruction of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02); PROVIDED,
HOWEVER, that the foregoing shall not relieve the Trustee of its obligation to
perform its duties under this Agreement. The Trustee shall not have any
responsibility for filing any financing or continuation statement in any
public office at any time or to otherwise perfect or maintain the perfection
of any security interest or lien granted to it hereunder.

          Section 8.04 Trustee May Own Certificates.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Certificates with the same rights as it would have if it
were not Trustee and may transact any banking and trust business with the
Seller, the Servicer, the Depositor or their Affiliates.

          Section 8.05 Seller to Pay Trustee Fees and Expenses.

          The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself its fees in an aggregate amount equal to
the Trustee Fee pursuant to Section 4.01 and, to the extent the sum of the
Interest Remittance Amount is at any time insufficient for such purpose, the
Seller shall pay such fees as reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of
an express trust) for all services rendered by it in the execution of the
trusts hereby created and in the exercise and performance of any of the powers
and duties hereunder of the Trustee, and the

                                     114

<PAGE>

Seller will pay or reimburse the Trustee upon their request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any of the provisions of this Agreement (including the
reasonable compensation and the expenses and disbursements of its counsel and
of all persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from such party's negligence or bad faith
or which is the responsibility of Certificateholders or the Trustee hereunder.
Notwithstanding any other provision of this Agreement, including Section
2.03(a) and Section 2.04, to the contrary, the Seller covenants and agrees to
indemnify the Trustee and its respective officers, directors, employees and
agents from, and hold each of them harmless against, any and all losses,
liabilities, damages, claims or expenses incurred in connection with any legal
action relating to this Agreement, the Certificates or incurred in connection
with the administration of the Trust, other than with respect to a party, any
loss, liability or expense incurred by reason of willful misfeasance, bad
faith or negligence of such party in the performance of their respective
duties hereunder or by reason of such party's reckless disregard of
obligations and duties hereunder. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Trustee be liable for special, indirect
or consequential loss or damage of any kind whatsoever (including but not
limited to lost profits), even if the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action. The
Trustee and any director, officer, employee or agent of the Trustee shall be
indemnified, to the extent not paid by the Seller pursuant to this Section, by
the Trust Fund and held harmless against any loss, liability or expense (not
including expenses, disbursements and advances incurred or made by the
Trustee, in the ordinary course of the Trustee's performance in accordance
with the provisions of this Agreement) incurred by the Trustee or such party
arising out of or in connection with the acceptance or administration of its
duties under this Agreement, other than any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance by the Trustee of its duties under this Agreement or by reason of
the reckless disregard of the Trustee's obligations and duties under this
Agreement. This section shall survive termination of this Agreement or the
resignation or removal of any Trustee hereunder.

          Section 8.06 Eligibility Requirements for Trustee.

          The Trustee hereunder shall at all times be a Department of Housing
and Urban Development and Federal Housing Administration approved mortgagee,
an entity duly organized and validly existing under the laws of the United
States of America or any state thereof, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000 and a minimum long-term debt rating of BBB by Fitch and S&P and a
long term debt rating of at least A1 or better by Moody's, and subject to
supervision or examination by federal or state authority. If such entity
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06, the combined capital and surplus of such entity
shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published. The principal office of the
Trustee (other than the initial Trustee) shall be in a state with respect to
which an Opinion of Counsel has been delivered to such Trustee at the time
such Trustee is appointed Trustee to the effect that the Trust will not be a
taxable entity under the laws of such state. In case at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
8.06, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.07.

                                     115

          Section 8.07 Resignation or Removal of Trustee.

          The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Depositor, the Servicer
and each Rating Agency. Upon receiving such notice of resignation, the
Depositor shall promptly appoint a successor Trustee by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor Trustee. If no successor Trustee shall
have been so appointed and having accepted appointment within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor
Trustee.

          If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Depositor, or if at any time the Trustee shall be
legally unable to act, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or of their property shall be appointed, or any public
officer shall take charge or control of the Trustee or of their property or
affairs for the purpose of rehabilitation, conservation or liquidation, then
the Depositor may remove the Trustee. If the Depositor or the Servicer removes
the Trustee under the authority of the immediately preceding sentence, the
Depositor shall promptly appoint a successor Trustee by written instrument, in
duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor Trustee.

          The Majority Certificateholders may at any time remove the Trustee
by written instrument or instruments delivered to the Servicer, the Depositor
and the Trustee and any expenses incurred by the Trustee in connection with
such removal shall be reimbursed to it by the Majority Certificateholders
promptly upon demand therefor; the Depositor shall thereupon use its best
efforts to appoint a successor Trustee in accordance with this Section.

          Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 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 Rating Agencies, the
Servicer and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective, and such successor Trustee,
without any further act, deed or conveyance, shall become fully vested with
all the rights, powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as Trustee. The Depositor, the
Servicer and the predecessor Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for 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 8.08 unless at the time of such acceptance such successor Trustee
shall be eligible under the

                                     116

<PAGE>

provisions of Section 8.06 and the appointment of such successor Trustee shall
not result in a downgrading of the Regular Certificates by any Rating Agency,
as evidenced by a letter from each Rating Agency.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 8.08, the successor Trustee shall mail notice of the appointment
of a successor Trustee hereunder to all Holders of Certificates at their
addresses as shown in the Certificate Register and to each Rating Agency.

          Section 8.09 Merger or Consolidation of Trustee.

          Any entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
entity succeeding to the business of the Trustee, shall be the successor of
the Trustee hereunder, provided such entity shall be eligible under the
provisions of Section 8.06 and 8.08, 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 of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust or any Mortgaged Property may at the time be located,
the Depositor 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 to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the Trust, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the 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 Servicer. If the Servicer shall not
have joined in such appointment within 15 days after the receipt by it of a
request so to do, or in the case a Servicer Event of Termination 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, and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08. The Servicer shall
be responsible for the fees of any co-trustee or separate trustee appointed
hereunder.

          Every separate trustee and co-trustee shall, to the extent permitted
by law, be appointed and act subject to the following provisions and
conditions:

          (i) all rights, powers, duties and obligations conferred or imposed
     upon the Trustee shall be conferred or imposed upon and exercised or
     performed by the Trustee and such separate trustee or co-trustee jointly
     (it being understood that such separate trustee or co-trustee is not
     authorized to act separately without the Trustee joining in such act),
     except to the extent that under any law of any jurisdiction in which any
     particular act or acts are to be performed (whether as Trustee hereunder
     or as successor to the Servicer

                                     117

<PAGE>

     hereunder), the Trustee shall be incompetent or unqualified to perform
     such act or acts, in which event such rights, powers, duties and
     obligations (including the holding of title to the Trust or any portion
     thereof in any such jurisdiction) shall be exercised and performed singly
     by such separate trustee or co-trustee, but solely at the direction of
     the Trustee;

          (ii) no trustee hereunder shall be held personally liable by reason
     of any act or omission of any other trustee hereunder; and

          (iii) the Servicer and the Trustee, acting jointly may at any time
     accept the resignation of or remove any separate trustee or co-trustee
     except that following the occurrence of a Servicer Event of Termination,
     the Trustee acting alone may accept the resignation or remove any
     separate trustee or co-trustee.

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

          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 Limitation of Liability.

          The Certificates are executed by the Trustee, not in its individual
capacity but solely as Trustee of the Trust, in the exercise of the powers and
authority conferred and vested in it by this Agreement. Each of the
undertakings and agreements made on the part of the Trustee in the
Certificates is made and intended not as a personal undertaking or agreement
by the Trustee but is made and intended for the purpose of binding only the
Trust.

          Section 8.12 Trustee May Enforce Claims Without Possession of
Certificates.

          (a) All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee
shall be brought in its own name or in its capacity as Trustee for the benefit
of all Holders of such Certificates, subject to the provisions of this
Agreement. Any recovery of judgment shall, after provision for the payment of
the reasonable compensation, expenses,

                                     118

<PAGE>

disbursement and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Certificateholders in respect of which such judgment
has been recovered.

          (b) The Trustee shall afford the Seller, the Depositor, the Servicer
and each Certificateholder upon reasonable notice during normal business
hours, access to all records maintained by the Trustee in respect of its
duties hereunder and access to officers of the Trustee responsible for
performing such duties. The Trustee shall cooperate fully with the Seller, the
Servicer, the Depositor and such Certificateholder and shall make available to
the Seller, the Servicer, the Depositor and such Certificateholder for review
and copying at the expense of the party requesting such copies, such books,
documents or records as may be requested with respect to the Trustee's duties
hereunder. The Seller, the Depositor, the Servicer and the Certificateholders
shall not have any responsibility or liability for any action or failure to
act by the Trustee and are not obligated to supervise the performance of the
Trustee under this Agreement or otherwise.

          Section 8.13 Suits for Enforcement.

          In case a Servicer Event of Termination or other default by the
Servicer or the Seller hereunder shall occur and be continuing, the Trustee
may proceed to protect and enforce its rights and the rights of the
Certificateholders under this Agreement by a suit, action or proceeding in
equity or at law or otherwise, whether for the specific performance of any
covenant or agreement contained in this Agreement or in aid of the execution
of any power granted in this Agreement or for the enforcement of any other
legal, equitable or other remedy, as the Trustee, being advised by counsel,
and subject to the foregoing, shall deem most effectual to protect and enforce
any of the rights of the Trustee and the Certificateholders.

          Section 8.14 Waiver of Bond Requirement.

          The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee post a bond or other surety with any
court, agency or body whatsoever.

          Section 8.15 Waiver of Inventory, Accounting and Appraisal
Requirement.

          The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

          Section 8.16 Compliance with National Housing Act of 1934.

          In performing its duties hereunder with respect to FHA Loans, the
Trustee shall comply with all requirements of the National Housing Act of
1934, as amended.

                             REMIC ADMINISTRATION

          Section 9.01 REMIC Administration.

          (a) REMIC elections as set forth in the Preliminary Statement shall
be made by the Trustee on Form 1066 or other appropriate federal tax or
information return for the taxable year ending on the last day of the calendar
year in which the Certificates are issued. The regular interests and residual
interest in each REMIC shall be as designated in the Preliminary Statement.

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

          (c) The Servicer shall pay any and all tax related expenses (not
including taxes) of each REMIC, including but not limited to any professional
fees or expenses related to audits or any administrative or judicial
proceedings with respect to each REMIC that involve the Internal Revenue
Service or state tax authorities, but only to the extent that (i) such
expenses are ordinary or routine expenses, including expenses of a routine
audit but not expenses of litigation (except as described in (ii)); or (ii)
such expenses or liabilities (including taxes and penalties) are attributable
to the negligence or willful misconduct of the Servicer in fulfilling its
duties hereunder. The Servicer shall be entitled to reimbursement of expenses
to the extent provided in clause (i) above from the Collection Account.

          (d) The Trustee shall prepare, sign and file, all of the REMICs'
federal and state tax and information returns as the direct representative of
each REMIC created hereunder. The expenses of preparing and filing such
returns shall be borne by the Trustee.

          (e) The Holder of the Residual Certificate at any time holding the
largest Percentage Interest thereof shall be the "tax matters person" as
defined in the REMIC Provisions (the "Tax Matters Person") with respect to
each REMIC and shall act as Tax Matters Person for each REMIC. The Trustee, as
agent for the Tax Matters Person, shall perform on behalf of each 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, if required by the Code, the REMIC Provisions, or
other such guidance, the Trustee, as agent for the Tax Matters Person, shall
provide (i) to the Treasury or other governmental authority such information
as is necessary for the application of any tax relating to the transfer of a
Residual Certificate to any disqualified person or organization and (ii) to
the Certificateholders such information or reports as are required by the Code
or REMIC Provisions. The Trustee, as agent for the Tax Matters Person, shall
represent each REMIC in any administrative or judicial proceedings relating to
an examination or audit by any governmental taxing authority, request an
administrative adjustment as to any taxable year of any REMIC, enter into
settlement agreements with any government taxing agency, extend any statute of
limitations relating to any item of any REMIC and otherwise act on behalf of
any REMIC in relation to any tax matter involving the Trust.

                                     120

<PAGE>

          (f) The Trustee, the Servicer and the Holders of Certificates shall
take any action or cause the REMIC to take any action necessary to create or
maintain the status of each REMIC as a REMIC under the REMIC Provisions and
shall assist each other as necessary to create or maintain such status.
Neither the Trustee, the Servicer nor the Holder of any Residual Certificate
shall take any action, cause any REMIC created hereunder 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 such REMIC as a REMIC or (ii) result in the imposition of a tax upon
such REMIC (including but not limited to the tax on prohibited transactions as
defined in Code Section 860F(a)(2) and the tax on prohibited contributions set
forth on Section 860G(d) of the Code) (either such event, an "Adverse REMIC
Event") unless the Trustee and the Servicer have received an Opinion of
Counsel (at the expense of the party seeking to take such action) to the
effect that the contemplated action will not endanger such status or result in
the imposition of such a tax. In addition, prior to taking any action with
respect to any REMIC created hereunder or the assets therein, or causing such
REMIC to take any action, which is not expressly permitted under the terms of
this Agreement, any Holder of a Residual Certificate will consult with the
Trustee and the Servicer, or their respective designees, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur
with respect to any REMIC, and no such Person shall take any such action or
cause any REMIC to take any such action as to which the Trustee or the
Servicer has advised it in writing that an Adverse REMIC Event could occur.

          (g) Each Holder of a Residual Certificate shall pay when due any and
all taxes imposed on each REMIC created hereunder by federal or state
governmental authorities. To the extent that such Trust taxes are not paid by
a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes
out of current or future amounts otherwise distributable to the Holder of the
Residual Certificate in the REMICs or, if no such amounts are available, out
of other amounts held in the Distribution Account, and shall reduce amounts
otherwise payable to Holders of regular interests in the related REMIC.

          (h) The Trustee, as agent for the Tax Matters Person, shall, for
federal income tax purposes, maintain books and records with respect to each
REMIC created hereunder on a calendar year and on an accrual basis.

          (i) No additional contributions of assets shall be made to any REMIC
created hereunder, except as expressly provided in this Agreement with respect
to Eligible Substitute Mortgage Loans.

          (j) Neither the Trustee nor the Servicer shall enter into any
arrangement by which any REMIC created hereunder will receive a fee or other
compensation for services.

          (k) On or before April 15th of each calendar year beginning in 2005,
the Servicer shall deliver to the Trustee and each Rating Agency an Officers'
Certificate stating the Servicer's compliance with the provisions of this
Section 9.01.

          (l) The Trustee will apply for an Employee Identification Number
from the Internal Revenue Service via a Form SS-4 or other acceptable method
for all tax entities and shall complete the Form 8811.

                                     121

<PAGE>

          (m) [Reserved].

          (n) In the event that any Person holds pro rata shares of the
ownership of the Class N Certificates and the Class X Certificates (any such
person, a "Proportionate Holder"), the Trustee shall treat such Person as the
holder of the ownership of the same pro-rate share of the Class X Interest. In
the event that any Person holds non-pro rata shares of the ownership of the
Class N Certificates and the Class X Certificates (any such Person, a
"Disproportionate Holder"), the Trustee shall treat such Person, and all other
Disproportionate Holders, as partners in a partnership that owns the Class X
Interest (other than the shares of the Class X Interest held by any
Proportionate Holders) for federal income tax purposes and shall not treat the
Class N and Class X Certificates held by the Disproportionate Holders as
interest in any REMIC created hereunder. By acquiring the Class N Certificates
and the Class X Certificates, the respective Holders will agree to treat the
Class N Certificates and the Class X Certificates in the manner described in
the preceding sentences for federal income tax purposes. In such event, (i) a
separate capital account shall be established and maintained for each Holder
of a Class N or Class X Certificate in accordance with Treasury Regulations
Section 1.704-1(b)(2)(iv), which shall be credited with income or gain and
debited by any expenses or losses and distributions allocable to such
Certificates, (ii) the Class N Certificates shall be allocated income in an
amount equal to interest at the Pass-Through Rate thereon and any original
issue discount that would be reportable thereon if the Class N Certificate
were a debt instrument issued on the date ownership of the Class N and Class X
Certificates is separated, with a principal balance equal to its Notional
Amount, (iii) the Class X and Class N Certificates shall be allocated income
with respect to all prepayments penalties (including amounts in connection
with the full or partial waiver of such prepayment penalties or premiums
pursuant to Section 3.01) in accordance with the allocation of such amounts
pursuant to Section 4.02(c), to the extent not allocated pursuant to Section
9.01(n)(ii) above, (iv) the Class X and Class N Certificates shall be
allocated accruals (under any reasonable method) of any "cap premiums" deemed
received on the date ownership of the Class X and Class N Certificates is
separated in respect of the obligation of the Class X Interest to pay LIBOR
Carryover Amounts, and shall be allocated expense in respect of any actual
payment of such LIBOR Carryover Amounts based on which one of such Classes
economically bears such expense, (v) the Class X Certificates shall be
allocated all remaining income and any expenses and Realized Losses with
respect to the Class X Interest, until the capital account of the Class X
Certificates is reduced to zero, and any remaining expenses or losses shall be
allocated to the Class N Certificates, (vi) neither the Class N Certificates
nor the Class X Certificates shall be responsible for restoring any deficit to
its capital account, (vii) upon termination of the Trust Fund pursuant to
Article X, all amounts available for distribution to Holders of the Class N
and Class X Certificates shall be distributed in accordance with their
positive capital account balances, first to the Class N Certificates until
their Notional Amount and any accrued but unpaid interest thereon are reduced
to zero, and then to the Class X Certificates, and (viii) the Trustee shall
maintain books and records with respect to the partnership on a calendar year
basis (unless a different taxable year shall be required by the Code) and
shall prepare or cause to be prepared, and cause the Holder of the largest
Percentage Interest of the Class X Certificates to sign and file or cause to
be filed all federal and state tax and information returns for the
partnership, and shall furnish or cause to be furnished ScheduleK-1's to the
Holders of the Class N and Class X Certificates at the time required by the
Code. Unless otherwise directed by a majority of the Percentage Interests of
the Class X and Class N Certificates, the Trustee shall not make an election
under Section 754 of the Code. The

                                     122

<PAGE>

Holder of the largest Percentage Interest of the Class X Certificates, by
acceptance of its Class X Certificate, agrees to act as "tax matters partner"
(within the meaning of Section 6231(a)(7) of the Code and to sign and timely
file all federal and state partnership tax and information returns prepared by
the Trustee pursuant to Section 9.01(n).

          (o) The Trustee shall treat the LIBOR Carryover Reserve Account as
an outside reserve fund within the meaning of Treasury Regulation 1.860G-2(h)
that is owned by the Class N and Class X Certificateholders and that is not an
asset of REMIC created hereunder. The Trustee shall treat the rights of the
Class A-1 Certificateholders to receive payments from the LIBOR Carryover
Reserve Account as rights in an interest rate cap contract written by the
Holders of the Class X Interest (in the case of amounts payable from the LIBOR
Carryover Reserve Account) in favor of the Class A-1 Certificateholders. Thus,
the Class A-1 Certificate shall be treated as representing ownership of not
only a REMIC Regular Interest, but also ownership of an interest in an
interest rate cap contract. For purposes of determining the issue price of the
REMIC Regular Interests, the Trustee shall assume that such interest rate cap
contract has a value of $10,000.

          Section 9.02 Prohibited Transactions and Activities.

          Neither the Seller, the Depositor, the Servicer nor the Trustee
shall sell, dispose of, or substitute for any of the Mortgage Loans, except in
a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the
bankruptcy of the Trust Fund, (iii) the termination of any REMIC created
hereunder pursuant to Article X of this Agreement, (iv) a substitution
pursuant to Article II of this Agreement or (v) a repurchase of Mortgage Loans
pursuant to Article II of this Agreement, nor acquire any assets for any
REMIC, nor sell or dispose of any investments in the Distribution Account for
gain, nor accept any contributions to either REMIC after the Closing Date,
unless it has received an Opinion of Counsel (at the expense of the party
causing such sale, disposition, or substitution) that such disposition,
acquisition, substitution, or acceptance will not (a) affect adversely the
status of any REMIC created hereunder as a REMIC or of the interests therein
other than the Residual Certificates as the regular interests therein, (b)
affect the distribution of interest or principal on the Certificates, (c)
result in the encumbrance of the assets transferred or assigned to the Trust
Fund (except pursuant to the provisions of this Agreement) or (d) cause any
REMIC created hereunder to be subject to a tax on prohibited transactions or
prohibited contributions pursuant to the REMIC Provisions.

          Section 9.03 Indemnification With Respect to Certain Taxes and Loss
                       of REMIC Status.

          In the event that any REMIC fails to qualify as a REMIC, loses its
status as a REMIC, or incurs federal, state or local taxes as a result of a
prohibited transaction or prohibited contribution under the REMIC Provisions
due to the negligent performance by the Servicer of its duties and obligations
set forth herein, the Servicer shall indemnify the Holder of the related
Residual Certificates against any and all losses, claims, damages, liabilities
or expenses ("Losses") resulting from such negligence; PROVIDED, HOWEVER, that
the Servicer shall not be liable for any such Losses attributable to the
action or inaction of the Trustee, the Depositor or the Holder of such
Residual Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Residual Certificate on which
the Servicer has

                                     123

<PAGE>

relied. The foregoing shall not be deemed to limit or restrict the rights and
remedies of the Holder of such Residual Certificate now or hereafter existing
at law or in equity. Notwithstanding the foregoing, however, in no event shall
the Servicer have any liability (1) for any action or omission that is taken
in accordance with and in compliance with the express terms of, or which is
expressly permitted by the terms of, this Agreement, (2) for any Losses other
than arising out of a negligent performance by the Servicer of its duties and
obligations set forth herein, and (3) for any special or consequential damages
to Certificateholders (in addition to payment of principal and interest on the
Certificates).

                                  ARTICLE X

                                  TERMINATION

          Section 10.01 Termination.

          (a) The respective obligations and responsibilities of the Seller,
the Servicer, the Depositor, the Trustee and the Certificate Registrar created
hereby (other than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate
upon notice to the Trustee upon the earliest of (i) the Distribution Date on
which the Certificate Principal Balance of each Class of Certificates has been
reduced to zero, (ii) the final payment or other liquidation of the last
Mortgage Loan in the Trust, and (iii) the optional purchase by the Servicer or
an Affiliate of the Servicer of the Mortgage Loans as described below.
Notwithstanding the foregoing, 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 Servicer or an Affiliate of the Servicer may, at its option,
terminate the Mortgage Loans in the Trust Fund and retire the Offered
Certificates, the Class B-3 Certificates and the Class B-4 Certificates on the
next succeeding Distribution Date upon which the aggregate current Pool
Balance is less than 10% of the aggregate Pool Balance of the Mortgage Loans
as of the Cut-off Date by purchasing all of the outstanding (i) Mortgage Loans
in the Trust Fund at a price equal to the sum of the outstanding Principal
Balance of the Mortgage Loans and except to the extent previously advanced by
the Servicer, accrued and unpaid interest thereon at the weighted average of
the Mortgage Interest Rates through the end of the Collection Period preceding
the final Distribution Date plus unreimbursed Servicing Advances, Advances and
any unpaid Servicing Fees allocable to such Mortgage Loans and (ii) REO
Properties in the Trust Fund at a price equal to their fair market value as
determined in good faith by the Servicer (the "Termination Price").

          In connection with any such purchase pursuant to the preceding
paragraph, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account all amounts then on deposit in the Collection Account
(less amounts permitted to be withdrawn by the Servicer pursuant to Section
3.07), which deposit shall be deemed to have occurred immediately following
such purchase.

                                     124

<PAGE>

          Any such purchase shall be accomplished by delivery to the Trustee
for deposit into the Distribution Account as part of Available Funds on the
Determination Date before such Distribution Date of the Termination Price.

          (b) Notice of any termination, specifying the Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee upon the Trustee receiving notice of such date from the Servicer,
by letter to the Certificateholders mailed not earlier than the 15th day of
the month preceding the month of such final distribution and not later than
the 15th day of the month of such final distribution specifying (1) the
Distribution Date upon which final distribution of the Certificates will be
made upon presentation and surrender of such Certificates at the office or
agency of the Trustee therein designated, (2) the amount of any such final
distribution and (3) that the Record Date otherwise applicable to such
Distribution Date is not applicable, distributions being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.

          (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Sections 4.01 and Section
4.02 for such Distribution Date.

          (d) In the event that all Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for
the benefit of such Certificateholders, and the Servicer (if the Servicer has
exercised its right to purchase the Mortgage Loans) or the Trustee (in any
other case) shall give a second written notice to the remaining
Certificateholders, to surrender their Certificates for cancellation and
receive the final distribution with respect thereto. If within nine months

          (a) In the event that the Servicer exercises its purchase option as
provided in Section 10.01, the Trust shall be terminated in accordance with
the following additional requirements, unless the Trustee shall have been
furnished with an Opinion of Counsel to the effect that the failure of the
Trust to comply with the requirements of this Section will not (i) result in
the imposition of taxes on "prohibited transactions" of the Trust as defined
in Section 860F of the Code or (ii) cause any REMIC constituting part of the
Trust Fund to fail to qualify as a REMIC at any time that any Certificates are
outstanding:

     liquidation of each REMIC and shall specify such date in the final
     federal income tax return of each REMIC;

          (ii) After the date of adoption of such plans of complete
     liquidation and at or prior to the final Distribution Date, the Trustee
     shall sell all of the assets of the Trust to the Servicer 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 in the following order of priority (A) (i) to the

     cash retained to meet claims) and the Trust shall terminate at such time.

          (b) By their acceptance of Certificates, the Holders thereof hereby
agree to appoint the Trustee as their attorney in fact to: (i) designate such
date of adoption of plans of complete liquidation and (ii) to take such other
action in connection therewith as may be reasonably required to carry out such
plans of complete liquidation all in accordance with the terms hereof.

                                  ARTICLE XI

                           MISCELLANEOUS PROVISIONS

          Section 11.01 Amendment.

          This Agreement may be amended from time to time by the Seller, the
Depositor, the Servicer and the Trustee; and without the consent of the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement
any provisions herein which may be defective or inconsistent with any other
provisions herein, (iii) to amend the provisions of Section 3.22 or (iv) to
make any other provisions with respect to matters or questions arising under
this Agreement, which shall not be inconsistent with the provisions of this
Agreement; PROVIDED, HOWEVER, that any such action listed in clause (i)
through (iv) above shall not adversely affect in any respect the interests of
any Certificateholder, as evidenced by (i) notice in writing to the Depositor,
the Servicer and the Trustee from the Rating Agencies that such action will
not result in the reduction or withdrawal of the rating of any outstanding
Class of Certificates with respect to which it is a Rating Agency, or (ii) an
Opinion of Counsel delivered to the Servicer and the Trustee.

                                     126

<PAGE>

          In addition, this Agreement may be amended from time to time by
Seller, the Depositor, the Servicer and the Trustee, with the consent of the
Majority Certificateholders for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement
or of modifying in any manner the rights of the Holders of Certificates;
PROVIDED, HOWEVER, that no such amendment or waiver shall (x) reduce in any
manner the amount of, or delay the timing of, payments on the Certificates
which are required to be made on any Certificate without the consent of the
Holder of such Certificate, (y) adversely affect in any material respect the
interests of the Holders of any Class of Certificates (as evidenced by (i)
notice in writing to the Depositor, the Servicer and the Trustee from the
Rating Agencies that such action will not result in the reduction or
withdrawal of the rating of any outstanding Class of Certificates with respect
to which it is a Rating Agency, or (ii) an Opinion of Counsel delivered to the
Servicer and the Trustee) in a manner other than as described in clause (x)
above, without the consent of the Holders of Certificates of such Class
evidencing at least a 66% Percentage Interest in such Class, or (z) reduce the
percentage of Voting Rights required by clause (y) above without the consent
of the Holders of all Certificates of such Class then outstanding. Upon
approval of an amendment, a copy of such amendment shall be sent to the Rating
Agencies. Prior to the execution of any amendment to this Agreement, the
Trustee shall be entitled to receive and rely upon an Opinion of Counsel (at
the expense of the Person seeking such amendment) stating that the execution
of such amendment is authorized or permitted by this Agreement. The Trustee
may, but shall not be obligated to, enter into any such amendment which
affects the Trustee's own rights, duties or immunities under this Agreement.

          Notwithstanding any provision of this Agreement to the contrary, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, delivered by (and at the expense
of) the Person seeking such Amendment, to the effect that such amendment will
not result in the imposition of a tax on any REMIC constituting part of the
Trust Fund pursuant to the REMIC Provisions or cause any REMIC constituting
part of the Trust to fail to qualify as a REMIC at any time that any
Certificates are outstanding and that the amendment is being made in
accordance with the terms hereof.

          Promptly after the execution of any such amendment the Trustee shall
furnish, at the expense of the Person that requested the amendment if such
Person is the Seller or the Servicer (but in no event at the expense of the
Trustee), otherwise at the expense of the Trust, a copy of such amendment and
the Opinion of Counsel referred to in the immediately preceding paragraph to
the Servicer and each Rating Agency.

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

          Section 11.02 Recordation of Agreement; Counterparts.

          To the extent permitted by applicable law, this Agreement is subject
to recordation in all appropriate public offices for real property records in
all the counties or other

                                     127

<PAGE>

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

          For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall together constitute
but one and the same instrument.

          Section 11.03 Limitation on Rights of Certificateholders.

          The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) entitle such
Certificateholder's legal representatives or heirs to claim an accounting or
to take any action or proceeding in any court for a partition or winding up of
the Trust, or (iii) otherwise affect the rights, obligations and liabilities
of the parties hereto or any of them.

          Except as expressly provided for herein, no Certificateholder shall
have any right to vote or in any manner otherwise control the operation and
management of the Trust, or the obligations of the parties hereto, nor shall
anything herein set forth or contained in the terms of the Certificates be
construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be
under any liability to any third 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 such Holder
previously shall have given to the Trustee a written notice of default and of
the continuance thereof, as herein provided, and unless also 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 its own name as Trustee hereunder and shall have offered to the Trustee
such reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 15 days
after its receipt of such notice, request and offer of indemnity, shall have
neglected or refused to institute any such action, suit or proceeding. It is
understood and intended, and expressly covenanted by each Certificateholder
with every other Certificateholder and the Trustee, that no one or more
Holders of Certificates shall have any right in any manner whatever 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, which priority or
preference is not otherwise provided for herein, 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 11.03 each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

          Notwithstanding any other provision of this Agreement, neither the

     THEIR AFFILIATES. THIS CERTIFICATE IS NOT GUARANTEED BY ANY AGENCY OR

          This certifies that Cede & Co. is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal
Balance of the Class A-1 Certificates) in that certain beneficial ownership
interest evidenced by all the Class A-1 Certificates in the Trust Fund created
pursuant to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among J.P. Morgan Acceptance Corporation I (hereinafter called
the "Depositor," which term includes any successor entity under the
Agreement), the Servicer, the Seller and the Trustee, a summary of certain of
the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned
in the Agreement. This Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the
Holder of this Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

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

                                    A-1-2

following (a "Distribution Date"), commencing on the first Distribution Date
specified above, to the Person in whose name this Certificate is registered on
the Business Day immediately preceding such Distribution Date (the "Record
Date"), from funds in the Distribution Account in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the
amount required to be distributed to the Holders of Class A-1 Certificates on
such Distribution Date pursuant to the Agreement provided, however, that if
any Class A-1 Certificate becomes a Definitive Certificate, the Record Date
for such Certificate will be the last Business Day of the month immediately
preceding the month in which the related Distribution Date occurs.

          All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate
Registrar in writing at least five Business Days prior to the Record Date
immediately prior to such Distribution Date and is the registered owner of
Class A-1 Certificates the aggregate Initial Certificate Principal Balance of
which is in excess of $5,000,000, or by check mailed by first class mail to
the address of the Person entitled thereto, as such name and address shall
appear on the Certificate Register, provided that the Certificate Registrar
may deduct a reasonable wire transfer fee from any payment made by wire
transfer. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency appointed by the Trustee for that purpose as provided
in the Agreement.

          The Class A-1 Pass-Through Rate on each Distribution Date will be a
rate per annum equal to the lesser of (i) the sum of one month LIBOR plus the
Class A-1 Certificate Margin and (ii) the related Rate Cap for the such
Distribution Date. Interest will accrue on the Class A-1 Certificates during
each Interest Accrual Period at the Class A-1 Pass-Through Rate.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-1 Certificates.

          The Class A-1 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 Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. 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

                                    A-1-3

<PAGE>

permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-2 Certificates.

          The Class A-2 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

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

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.

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

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

thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

the "Depositor," which term includes any successor entity under the
Agreement), the Servicer, the Seller and the Trustee, a summary of certain of
the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned
in the Agreement. This Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the
Holder of this Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

                                    A-3-2

<PAGE>

          Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the last Business Day of the month immediately
preceding the month in which the related Distribution Date occurs or the
closing date in the case of the first Distribution Date (the "Record Date"),
from funds in the Distribution Account in an amount equal to the product of
the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of Class A-3 Certificates on such
Distribution Date pursuant to the Agreement.

          All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate
Registrar in writing at least five Business Days prior to the Record Date
immediately prior to such Distribution Date and is the registered owner of
Class A-3 Certificates the aggregate Initial Certificate Principal Balance of
which is in excess of $5,000,000, or by check mailed by first class mail to
the address of the Person entitled thereto, as such name and address shall
appear on the Certificate Register, provided that the Certificate Registrar
may deduct a reasonable wire transfer fee from any payment made by wire
transfer. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency appointed by the Trustee for that purpose as provided
in the Agreement.

          The Class A-3 Pass-Through Rate on each Distribution Date will be a
rate per annum equal to the lesser of (i) the Class A-3 Fixed Rate and (ii)
the related Rate Cap for the such Distribution Date. Interest will accrue on
the Class A-3 Certificates during each Interest Accrual Period at the Class
A-3 Pass-Through Rate.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-3 Certificates.

          The Class A-3 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 Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. 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

                                    A-3-3

<PAGE>

whether or not notation of such consent is made upon this Certificate. The
Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

          Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the last Business Day of the month immediately
preceding the month in which the related Distribution Date occurs or the
closing date in the case of the first Distribution Date (the "Record Date"),
from funds in the Distribution Account in an amount equal to the product of
the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of Class A-4 Certificates on such
Distribution Date pursuant to the Agreement.

          All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate
Registrar in writing at least five Business Days prior to the Record Date
immediately prior to such Distribution Date and is the registered owner of
Class A-4 Certificates the aggregate Initial Certificate Principal Balance of
which is in excess of $5,000,000, or by check mailed by first class mail to
the address of the Person entitled thereto, as such name and address shall
appear on the Certificate Register, provided that the Certificate Registrar
may deduct a reasonable wire transfer fee from any payment made by wire
transfer. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency appointed by the Trustee for that purpose as provided
in the Agreement.

          The Class A-4 Pass-Through Rate on each Distribution Date will be a
rate per annum equal to the lesser of (i) the Class A-4 Fixed Rate and (ii)
the related Rate Cap for the such Distribution Date. Interest will accrue on
the Class A-4 Certificates during each Interest Accrual Period at the Class
A-4 Pass-Through Rate.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-4 Certificates.

          The Class A-4 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 Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. 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

                                    A-4-3
<PAGE>

whether or not notation of such consent is made upon this Certificate. The
Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

first Distribution Date (the "Record Date"), from funds in the Distribution
Account in an amount equal to the product of the Percentage Interest evidenced

          All distributions to the Holder of this Certificate under the

entitled thereto if such Person shall have so notified the Certificate

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-5 Certificates.

          The Class A-5 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 Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. 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

                                    A-5-3
<PAGE>

permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

following (a "Distribution Date"), commencing on the first Distribution Date
specified above, to the Person in whose name this Certificate is registered on
the last Business Day of the month immediately preceding the month in which
the related Distribution Date occurs or the closing date in the case of the
first Distribution Date (the "Record Date"), from funds in the Distribution
Account in an amount equal to the product of the Percentage Interest evidenced
by this Certificate and the amount required to be distributed to the Holders
of Class A-6 Certificates on such Distribution Date pursuant to the Agreement.

          All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate
Registrar in writing at least five Business Days prior to the Record Date
immediately prior to such Distribution Date and is the registered owner of

transfer. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency appointed by the Trustee for that purpose as provided
in the Agreement.

          The Class A-6 Pass-Through Rate on each Distribution Date will be a
rate per annum equal to the lesser of (i) the Class A-6 Fixed Rate and (ii)
the related Rate Cap for the such Distribution Date. Interest will accrue on
the Class A-6 Certificates during each Interest Accrual Period at the Class
A-6 Pass-Through Rate.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class A-6 Certificates.

          The Class A-6 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 Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. 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

                                    A-6-3

<PAGE>

permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange herefor or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

          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

representing a Percentage Interest in the Class B-3 Certificates.

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.

          This certificate is subordinated in right of payment to the Class A
Certificates, the Class M Certificates, the Class B-1 Certificates and the
Class B-2 Certificates as described in the Pooling and Servicing Agreement
referred to herein.

          The Agreement permits, with certain exceptions therein provided, the

Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the

<PAGE>

Depositor, the Servicer, the Seller and the Trustee with the consent of the
Holders of Certificates entitled to the Voting Rights identified in the
agreement. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof,
in certain limited circumstances, without the consent of the Holders of any of
the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations evidencing the
same aggregate Percentage Interest will be issued to the designated transferee
or transferees.

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

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the

                                    B-3-5

Mortgage Loans at the time of purchase being 10% or less of the Cut-off Date
Principal Balance of the Mortgage Loans.

          The recitals contained herein shall be taken as statements of the

rate per annum equal to the lesser of (i) the Class B-4 Fixed Rate and (ii)
the related Rate Cap for such Distribution Date. Interest will accrue on the
Class B-4 Certificates during each Interest Accrual Period at the Class B-4
Pass-Through Rate.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing a Percentage Interest in the Class B-4 Certificates.

          The Class B-4 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.

          This certificate is subordinated in right of payment to the Class A
Certificates, the Class M Certificates, the Class B-1 Certificates, the Class
B-2 Certificates and the Class B-3 Certificates as described in the Pooling
and Servicing Agreement referred to herein.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the

<PAGE>

Depositor, the Servicer, the Seller and the Trustee with the consent of the
Holders of Certificates entitled to the Voting Rights identified in the
agreement. 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 that transfer
is made pursuant to an effective registration statement under the 1933 Act and
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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) that the Depositor and the Certificate Registrar shall require an Opinion
of Counsel satisfactory to them that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not be an
expense of the Depositor, the Trustee or the Certificate Registrar, in their
respective capacities as such. None of the Depositor, the Certificate
Registrar nor the Trustee is obligated to register or qualify the Class of
Certificates specified on the face hereof under the 1933 Act or any other
securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any 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 or any interest herein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate

                                    B-4-5

accounts in which such plans, accounts or arrangements are invested that are
subject to the fiduciary responsibility provisions of ERISA and Section 4975
of the Code ("Plans") or any person who is directly or indirectly purchasing
this Certificate or interest herein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan unless the opinion letter in section 5.02
of the Pooling and Servicing Agreement is provided.

          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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

          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.

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 that transfer
is made pursuant to an effective registration statement under the 1933 Act and
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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) that the Depositor and the Certificate Registrar shall require an Opinion
of Counsel satisfactory to them that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not be an
expense of the Depositor, the Trustee or the Certificate Registrar, in their
respective capacities as such. None of the Depositor, the Certificate
Registrar nor the Trustee is obligated to register or qualify the Class of
Certificates specified on the face hereof under the 1933 Act or any other
securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any 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 or any interest herein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested that are subject to the fiduciary
responsibility provisions of ERISA and Section 4975 of the Code ("Plans") or
any person who is directly or indirectly purchasing this Certificate or
interest herein on behalf of, as named fiduciary of, as trustee of, or with
assets of a Plan.

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes 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 to cease to qualify as two separate REMICs or cause the
imposition of a tax upon the Trust.

          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.

<PAGE>

          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

of a 66% Percentage Interest of the Class R-X Certificates, or by check mailed
by first class mail to the address of the Person entitled thereto, as such

payment made by wire transfer. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee
of the pendency of such distribution and only upon presentation and surrender
of this Certificate at the office or agency appointed by the Trustee for that
purpose as provided in the Agreement.

          This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates of the Series
specified on the face hereof (herein called the "Certificates") and
representing the Percentage Interest specified on the face hereof.

          The Class R-X 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 Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the
Servicer, the Seller and the Trustee with the consent of the Holders of
Certificates entitled to the Voting Rights identified in the agreement. 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.

<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 that transfer
is made pursuant to an effective registration statement under the 1933 Act and
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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) that the Depositor and the Certificate Registrar shall require an Opinion
of Counsel satisfactory to them that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not be an
expense of the Depositor, the Trustee or the Certificate Registrar, in their
respective capacities as such. None of the Depositor, the Certificate
Registrar nor the Trustee is obligated to register or qualify the Class of
Certificates specified on the face hereof under the 1933 Act or any other
securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any 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 or any interest herein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested that are subject to the fiduciary
responsibility provisions of ERISA and Section 4975 of the Code ("Plans") or
any person who is directly or indirectly purchasing this Certificate or
interest herein on behalf of, as named fiduciary of, as trustee of, or with
assets of a Plan unless the opinion letter in Section 5.02 of the Pooling and
Servicing Agreement is provided.

          The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes 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 to cease to qualify as four separate REMICs or cause the
imposition of a tax upon the Trust.

          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 Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

          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 limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same

          No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) that the Depositor and the Certificate Registrar shall require an Opinion

expense of the Depositor, the Trustee or the Certificate Registrar, in their
respective capacities as such. None of the Depositor, the Certificate
Registrar nor the Trustee is obligated to register or qualify the Class of
Certificates specified on the face hereof under the 1933 Act or any other
securities law or to take any action not otherwise required under the

qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and the 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 or any interest herein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans,

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

<PAGE>

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

liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the

Mortgage Loans. The Agreement permits, but does not require, the party
designated in the Agreement to purchase from the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

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

the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the 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 Servicer and the Trustee and the Certificate
Registrar and any agent of the Depositor, the 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 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 or on behalf of 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 the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the
Trust Fund of all 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 the Trust Fund all Mortgage Loans
and all property acquired in respect of any Mortgage Loan at a price
determined as provided in the Agreement. The exercise of such right will
effect early retirement of the Certificates; however, such right to purchase
is subject to the aggregate Principal Balance of the Mortgage Loans at the
time of purchase being 10% or less of the Cut-off Date Principal Balance of
the Mortgage Loans.

          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.

                                  ARTICLE III

              REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH

          Section 3.01 SELLER REPRESENTATIONS AND WARRANTIES RELATING TO THE
MORTGAGE LOANS. The Seller hereby represents and warrants to the Purchaser,
with respect to the Mortgage Loans, that as of the Closing Date or as of such
date specifically provided herein:

          (a) The information set forth in the Mortgage Loan Schedule is
complete, true and correct as of the Cut-off Date.

          (b) There are no delinquent taxes, ground rents, water charges,
sewer rents, assessments, including assessments payable in future
installments, or other outstanding charges affecting the related Mortgaged
Property.

          (c) The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments, recorded in the applicable public recording office if necessary
to maintain the lien priority of the Mortgage and the interests of the
Certificateholders, and which have been delivered to the Trustee; the
substance of any such waiver, alteration or modification has been approved by
the title insurer, to the extent required by the related policy, and is
reflected on the Mortgage Loan Schedule. No instrument of waiver, alteration
or modification has been executed, and no Mortgagor has been released, in
whole or in part, except, in connection with an assumption agreement approved
by the title insurer, to the extent required by the policy and, in the case of
an FHA Loan, to the extent required by the related Insurance Agreement, and
which assumption agreement has been delivered to the Trustee and the terms of
which are reflected in the Mortgage Loan Schedule.

          (d) The Mortgage Note and the Mortgage are not subject to any right
of rescission, set-off, counterclaim or defense, including the defense of
usury, 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 right of rescission,
set-off, counterclaim or defense, including the defense of usury and no such
right of rescission, set-off, counterclaim or defense has been asserted with
respect thereto.

          (e) All buildings upon the Mortgaged Property are insured by a
generally acceptable insurer against loss by fire, hazards of extended
coverage and such other hazards as

                                      5

<PAGE>

are customary in the area where the Mortgaged Property is located, pursuant to
insurance policies conforming to the requirements of the Pooling and Servicing
Agreement. All such insurance policies contain a standard mortgagee clause
naming the Seller, its successors and assigns as mortgagee and all premiums
thereon have been paid. If upon origination of the Mortgage Loan, the
Mortgaged Property was in an area identified on a Flood Hazard Map or Flood
Insurance Rate Map issued by the Federal Emergency Management Agency as having
special flood hazards (and such flood insurance has been made available) a
flood insurance policy meeting the requirements of the current guidelines of
the Federal Insurance Administration is in effect which policy conforms to the
requirements of the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). The Mortgage obligates the
Mortgagor thereunder to maintain all such insurance at the Mortgagor's cost
and expense, and on the Mortgagor's failure to do so, authorizes the holder of
the Mortgage to maintain such insurance at the Mortgagor's cost and expense
and to seek reimbursement therefor from the Mortgagor. All acts required to be
performed to preserve the rights and remedies of the Trustee in any such
insurance policies have been performed, including, without limitation, any
necessary notifications of insurers and assignments of policies or interests
therein.

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

          (g) The Mortgage has not been satisfied, canceled, subordinated
(other than with respect to second lien loans, the subordination to the first
lien loan) rescinded, in whole or in part, and the Mortgaged Property has not
been released from the lien of the Mortgage, in whole or in part, nor has any
instrument been executed that would effect any such satisfaction,
cancellation, subordination, rescission or release.

          (h) The Mortgage is a valid, existing and enforceable first or
second lien on the Mortgaged Property, including all improvements on the
Mortgaged Property subject only to (1) the lien of current real property taxes
and assessments not yet due and payable, (2) covenants, conditions and
restrictions, rights of way, easements and other matters of the public record
as of the date of recording being acceptable to mortgage lending institutions
generally and, in the case of FHA Loans, to the FHA, and specifically referred
to in the lender's title insurance policy delivered to the originator of the
Mortgage Loan, (3) other matters to which like properties are commonly subject
which do not materially interfere with the benefits of the security intended
to be provided by the Mortgage or the use, enjoyment, value or marketability
of the related Mortgaged Property and which may not in any way prevent
realization of the benefits of the related Insurance Agreement, if applicable
and (4) with respect to any second lien mortgage loan, the lien of the related
first mortgage loan. Any security agreement, chattel mortgage or equivalent
document related to and delivered in connection with the Mortgage Loan
establishes and creates a valid, existing and enforceable first or second lien
and first or second priority

                                      6

<PAGE>

security interest on the property described therein and the Seller has full
right to sell and assign the same to the Purchaser.

          (i) 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.

          (j) The proceeds of the Mortgage Loan have been fully disbursed to
or for the account of the Mortgagor and there is no obligation for the
mortgagee to advance additional funds thereunder and any and all requirements
as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage have been paid, and the Mortgagor is not entitled to
any refund of any amounts paid or due to the mortgagee pursuant to the
Mortgage Note or Mortgage.

          (k) Immediately prior to the transfer and assignment contemplated
herein, the Seller was the sole owner and holder of the Mortgage Loans and has
good and marketable title to each Mortgage Loan, free and clear of any and all
liens, pledges, charges, claims, participation interests, mortgages, security
interests or encumbrances or other interests of any nature and has full right
and authority to sell and assign the same.

          (l) Each Mortgage Loan is covered by an ALTA mortgagee title
insurance policy acceptable to FNMA or FHLMC, issued by a title insurer
acceptable to (1) FNMA and FHLMC, in the case of a conventional Mortgage Loan
and (2) the FHA, in the case of an FHA Loan, and qualified to do business in
the jurisdiction where the Mortgaged Property is located, insuring (subject to
the exceptions contained in (h)(1) and (2) above) the Seller, its successors
and assigns as to the first or second priority lien of the Mortgage in the
original principal amount of the Mortgage Loan and against any loss by reason
of the invalidity or unenforceability of the lien resulting from the
provisions of the Mortgage providing for adjustment in the mortgage interest
rate and/or monthly payment including any negative amortization thereunder.
Additionally, such mortgagee title insurance policy affirmatively insures
ingress and egress to and from the Mortgaged Property, and against
encroachments by or upon the Mortgaged Property or any interest therein. The
Seller is the sole insured of such mortgagee title insurance policy, and such
lender's title insurance policy is in full force and effect and will be in
full force and effect upon the consummation of the transactions contemplated
by this Agreement. No claims have been made under such mortgagee 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 mortgagee title insurance policy.

          (m) There are no mechanics' or similar liens or claims which have
been filed for work, labor or material (and no rights are outstanding that
under law could give rise to such lien) affecting the related Mortgaged
Property which are or may be liens prior to, or equal or coordinate with, the
lien of the related Mortgage.

          (n) The collection practices used by the Servicer with respect to
each Mortgage Note and Mortgage have been in all respects legal, proper,
prudent and customary in the mortgage servicing industry.

                                      7

<PAGE>

          (o) The Mortgage and related Mortgage Note contain customary and
enforceable provisions such as to render the rights and remedies of the holder
thereof adequate for the realization against the Mortgaged Property of the
benefits of the security provided thereby, including, (1) in the case of a
Mortgage designated as a deed of trust, by trustee's sale, and (2) otherwise
by judicial foreclosure. There is no homestead or other exemption available to
the Mortgagor which would interfere with the right to sell the Mortgaged
Property at a trustee's sale or the right to foreclose the Mortgage. The
Mortgagor has not notified the Seller and the Seller has no knowledge of any

Relief Act, 50 U.S.C. App. ss.ss. 501-596, enacted on December 19, 2003, as
amended.

collateral except the lien of the corresponding Mortgage on the Mortgaged
Property and the security interest of any applicable security agreement or
chattel mortgage.

          (q) In the event the Mortgage constitutes 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 the 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.

          (r) No Mortgage Loan contains provisions pursuant to which monthly
payments are (1) paid or partially paid with funds deposited in any separate
account established by the Seller, the Mortgagor, or anyone on behalf of the
Mortgagor, (2) paid by any source other than the Mortgagor or (3) contains any
other similar provisions which may constitute a "buydown" provision. The
Mortgage Loan is not a graduated payment mortgage loan and the Mortgage Loan
does not have a shared appreciation or other contingent interest feature.

          (s) The Mortgage Note, the Mortgage, the Assignment and any other
documents required to be delivered with respect to each Mortgage Loan pursuant
to Section 2.02 hereof have been delivered to the Purchaser or its designee,
all in compliance with the specific requirements of Section 2.02 hereof.

          (t) If the residential dwelling on the Mortgaged Property is a
condominium unit or a unit in a planned unit development (other than a de
minimis planned unit development) such condominium or planned unit development
project meets FNMA's eligibility requirements.

constitute other than real property under applicable state law.

          (v) The rights with respect to each Mortgage Loan are assignable by

have been obtained on or before the Closing Date.

          (w) The Mortgage Loans are not being transferred by the Seller with
any intent to hinder, delay or defraud any creditors of the Seller.

                                      8

<PAGE>

          (x) All parties which have had any interest in each Mortgage Loan,
whether as mortgagee, assignee, pledgee or otherwise, and including, without
limitation, the Seller, are (or during the period in which they held and
disposed such interest, were) in compliance with any and all applicable
licensing requirements of the laws of the state wherein the property securing
the Mortgage is located to the extent that any noncompliance thereunder would
affect the value or marketability of the Mortgage Loans.

          (y) To the best of Seller's knowledge, the Mortgaged Property is
free from any and all toxic or hazardous substances and there exists no
violation of any local, state or federal environmental law, rule or
regulation.

          (z) The Mortgaged Property is free from material damage.

          (aa) Each Mortgage Loan has been serviced by the Servicer in

opinion regarding the related Mortgaged Property indicating an appraised value
equal to the appraised value identified for such Mortgaged Property on the
Mortgage Loan Schedule. Each appraisal has been prepared on FNMA or FHLMC
forms.

          (gg) No improvements on any Mortgaged Property encroach on adjoining
properties (and in the case of a condominium unit, such improvements are
within the project with respect to that unit), and no improvements on
adjoining properties encroach upon such Mortgaged Property unless there exists
in the applicable Mortgage File a title policy with endorsements which insure
against losses sustained by the insured as a result of such encroachments.

          (hh) Each Insurance Agreement is in full force and effect and will
be in full force and effect upon the consummation of the transactions
contemplated by this Agreement.

in the possession of, or under the control of, the Servicer and there exists
no deficiencies in connection therewith for which customary arrangements for
repayment thereof have not been made. No escrow deposits or escrow advances or
other charges or payments due the Servicer have been capitalized under any
Mortgage or the related Note.

                                      9

<PAGE>

          (jj) No Mortgage Loan is subject to any pending bankruptcy or
insolvency proceeding. To the Seller's best knowledge, no material litigation
or lawsuit relating to any Mortgage Loan is pending.

          (kk) The Seller used no selection procedures that identified the
Mortgage Loans as being less desirable or valuable than other comparable
mortgage loans acquired by the Seller.

          (ll) The sale, transfer, assignment and conveyance of Mortgage Loans
by the Seller pursuant to this Agreement will not result in any tax, fee or
governmental charge (other than income taxes and related taxes) payable by the
Seller, the Depositor or the Trustee to any federal, state or local government
other than taxes which have or will be paid by the Seller as due ("Transfer
Taxes"). In the event that the Depositor or the Trustee receives actual notice
of any Transfer Taxes arising out of the transfer, assignment and conveyance
of the Mortgage Loans, other than any taxes to be paid by the creditor, on
written demand by the Depositor, or the Trustee, or upon the Seller's
otherwise being given notice thereof by the Depositor or the Trustee, the
Seller shall pay, and otherwise indemnify and hold the Depositor and the
Trustee harmless, on an after-tax basis, from and against any and all such
Transfer Taxes (it being understood that the Certificateholders, the Trustee
and the Depositor shall have no obligation to pay such Transfer Taxes).

          (mm) With respect to each Mortgage Loan that is a "mortgage" as such
term is defined in 15 U.S.C. 1602(aa), no obligor has or will have a claim or
defense under such Mortgage Loan as a result of a violation of the Home
Ownership and Equity Protection Act of 1994.

eligible condominium project, (D) detached or semi-detached one-family
dwelling in a planned unit development, (E) multi-family dwelling or townhouse
or (F) mobile home or manufactured dwelling which constitutes real property or
(ii) unimproved by any residential dwelling.

          (oo) There is no default, breach, violation or event of acceleration
existing under the Mortgage or the Mortgage Note and no event which, with the
passage of time or with notice and the expiration of any grace or cure period,
would constitute a default, breach, violation or event of acceleration, and
the Seller has not waived any default, breach, violation or event of
acceleration except, in the case of an FHA Loan, by written instruments, and
the substance of which waiver has been approved by the FHA to the extent
required by the applicable Insurance Agreement.

          (pp) The Seller has no actual knowledge that with respect to any
Mortgage Loan (1) the Servicer has sent a notice of default to the related
Mortgagor which the Servicer is currently seeking to enforce, or (2) any
foreclosure proceedings have been commenced or acceleration been declared
which is currently pending. The Seller is not transferring any

                                      10

Mortgage Loan to the Purchaser with the intention or knowledge that the
Purchaser or the Trust will acquire the related Mortgaged Property.

          (qq) With respect to any Mortgage Loan that is secured by a second
lien on the related Mortgaged Property, either (i) no consent for the Mortgage
Loan is required by the holder of any related senior lien or (ii) such consent
has been obtained and is contained in the Mortgage File.

          (rr) In any case in which a Mortgage Loan is secured by a second
lien and a senior lien on the related Mortgaged Property provides for negative
amortization or deferred interest, the balance of such senior lien on the
related Mortgaged Property used to calculate the Combined Loan to Value Ratio
for the Mortgage Loan is based on the maximum amount of negative amortization
possible under such senior loan.

          (ss) With respect to a Mortgage Loan which is a second lien, as of
the date hereof, the Seller has not received a notice of default of a senior
lien on the related Mortgaged Property which has not been cured.

          (tt) No Mortgage Loan is delinquent. The Seller has not waived any
default, breach, violation or event of acceleration, and the Seller has not
taken any action to waive any default, breach, violation or event of
acceleration, with respect to any Mortgage Loan.

          (uu) Each Mortgage Loan is a "qualified Mortgage" within the meaning
of Section 860 G(a)(3) of the Code. (vv) With respect to any Adjustable-Rate
Mortgage Loan, all rate adjustments have been performed in accordance with the
terms of the related Mortgage Note or subsequent modifications, if any.

          (ww) At the time of their origination, all FHA Loans conformed to
HUD origination guidelines.

          (xx) Each Mortgage Loan is directly secured by a Mortgage on a
residential property, and either (1) substantially all of the proceeds of the
Mortgage Loan were used to acquire, improve or protect the portion of the
residential property that consists of an interest in real property (within the
meaning of Treasury Regulations Sections 1.856-3(c) and 1.856-3(d)) and the
interest in real property was the only security for the Mortgage Loan as of
the Testing Date (as defined below), or (2) the fair market value of the
interest in real property which secures the Mortgage Loan was at least equal
to 80% of the principal amount of the Mortgage Loan (a) as of the Testing
Date, or (b) as of the Closing Date. For purposes of the previous sentence,
(1) the fair market value of the referenced interest in real property shall
first be reduced by (a) the amount of any lien on the interest in real
property that is senior to the Mortgage Loan, unless the Mortgage Loan
includes both a first lien loan and a second lien loan on the same Mortgaged
Property, in which case the 80% test shall be applied in the aggregate, and
(b) a proportionate amount of any lien on the interest in real property that
is on a parity with the Mortgage Loan, and (2) the "Testing Date" shall be the
date on which the referenced Mortgage Loan was originated unless (a) the
Mortgage Loan was modified after the date of its origination in a manner that
would cause "significant modification" of the Mortgage Loan within the meaning
of Treasury

                                      11

<PAGE>

Regulations Section 1.1001-3, and (b) the "significant modification" did not
occur at a time when the Mortgage Loan was in default or when default with
respect to the Mortgage Loan was reasonably foreseeable.

          (yy) With respect to each Mortgage Loan that is a mobile or
manufactured housing unit, such unit is a "single family residence" within the
meaning of Section 25(e)(1) of the Code, and has a minimum of 400 square feet
of living space, a minimum width of 102 inches and is of a kind customarily
used at a fixed location.

          (zz) Any written agreement between the Mortgagor in respect of a
Mortgage Loan and the Servicer modifying such Mortgagor's obligation to make
payments under the Mortgage Loan (such modified Mortgage Loan, a "Modified
Mortgage Loan") involved the application of the Seller's underwriting
standards or some assessment of the Mortgagor's ability to repay the Modified
Mortgage Loan.

          (aaa) No Mortgage Loan is covered by the Home Ownership and Equity
Protection Act of 1994 ("HOEPA") and no Mortgage Loan is in violation of any
state law or ordinance similar to HOEPA.

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

          (ccc) No Mortgage Loan originated on or after October 1, 2002 will
impose a Prepayment Charge for a term in excess of three years. Any Mortgage
Loan originated prior to such date will not impose a Prepayment Charge in
excess of five years.

          (ddd) The Servicer has fully furnished and will continue to fully
furnish, in accordance with the Fair Credit Reporting Act and its implementing
regulations, accurate and complete information (e.g., favorable and
unfavorable) on its borrower credit files to Equifax, Experian and Trans Union

basis.

          (eee) There is no Mortgage Loan in the Trust Fund that was
originated on or after October 1, 2002 and before March 7, 2003, which is
secured by property located in the State of Georgia.

          (fff) There is no Mortgage Loan in the Trust Fund that was
originated on or after March 7, 2003, which is a "high cost home loan" as
defined under the Georgia Fair Lending Act ("GFLA").

          (ggg) (a) No Mortgage Loan is classified as a high cost mortgage
loan under HOEPA; and (b) no Mortgage Loan in the Trust Fund is a "high cost
home," "covered" (excluding home loans defined as "covered home loans"
pursuant to clause (1) of the definition of that term in the New Jersey Home
Ownership Security Act of 2002), "high risk home" or "predatory" loan under
any other applicable state, federal or local law (or a similarly classified
loan using different terminology under a law imposing heightened regulatory
scrutiny or additional legal liability for residential mortgage loans having
high interest rates, points and/or fees).

                                      12

<PAGE>

          (hhh) Each Mortgage Loan at the time it was made complied in all
material respects with applicable local, state and federal laws, including,

local laws.

          (lll) All mortgage loans are originated in compliance with state,

          (mmm) No Mortgage Loan is a High Cost Loan or a Covered Loan, as
applicable (as such terms are defined in Appendix E of the Standard & Poor's
Glossary For File Format For LEVELS(R) Version 5.6 Revised (attached hereto as
Exhibit 1); provided that no representation and warranty is made in this
clause 3.01(mmm) with respect to any Mortgage Loan secured by property located
in the states of Kansas or West Virginia, the City of Los Angeles, California
or the City of Oakland, California.

          With respect to the representations and warranties set forth in
Section 3.01(aaa), (bbb), (ccc), (ddd), (eee), (fff), (ggg) and (mmm) that are
made to the best of the Seller's knowledge or as to which the Seller has no
knowledge, if it is discovered by the Depositor, the Seller, the Servicer or
the Trustee, as set forth in Section 2.04 of the Pooling and Servicing
Agreement, that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of
the related Mortgage Loan or the interest therein of the Purchaser or the
Purchaser's assignee, transferee or designee for the benefit of the
Certificateholders then, notwithstanding the Seller's lack of knowledge with
respect to the substance of such representation and warranty being inaccurate
at the time the representation or warranty was made, such inaccuracy shall be
deemed a breach of the applicable representation or warranty.

          Upon discovery by the Depositor, the Seller, the Servicer, the
Purchaser or any assignee, transferee or designee of the Purchaser of a breach
of any of the representations and warranties contained in this Article III or
Section 2.04 of the Pooling and Servicing Agreement 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 for the
benefit of the Certificateholders, the party discovering the breach shall give
prompt written notice to the others and in no event later than two Business
Days from the date of such discovery. It is understood by the parties hereto
that a breach of the representations and warranties made in this Section 3.01
will be deemed to materially and adversely affect the value of the related
Mortgage Loan or the interest therein of the Purchaser or the Purchaser's
assignee. Within 90 days of the earlier of its discovery or its receipt of
notice of any such breach of a representation or warranty, the Seller shall
promptly cure such breach in all material respects, or in the event such
defect or breach

                                      13

<PAGE>

cannot be cured, the Seller shall repurchase the affected Mortgage Loan or
cause the removal of such Mortgage Loan from the Trust Fund and substitute for
it one or more Eligible Substitute Mortgage Loans, in either case, in
accordance with Section 2.03 of the Pooling and Servicing Agreement.

          Upon discovery or receipt of written notice by the Seller of any
materially defective document in, or that a document is missing from, a
Mortgage File, the Seller shall have 120 days to cure such defect or 150 days
following the Closing Date, in the case of missing Mortgages or Assignments
(or within 90 days of the earlier of the Seller's discovery or receipt of
notification if such defect would cause the Mortgage Loan not to be a
"qualified mortgage" for REMIC purposes) or in the event such defect cannot be
cured, the Seller shall repurchase the affected Mortgage Loan or cause the
removal of such Mortgage Loan from the Trust Fund and substitute for it one or
more Eligible Substitute Mortgage Loans, in either case, within such time
periods and in accordance with Section 2.03 of the Pooling and Servicing
Agreement.

          It is understood and agreed that the representations and warranties
set forth in this Section 3.01 shall survive delivery of the respective
Mortgage Files to the Trustee or its agent, on behalf of the Purchaser and
shall inure to the benefit of the Certificateholders notwithstanding any
restrictive or qualified endorsement or assignment.

          It is understood and agreed that the obligations of the Seller set
forth in this Section 3.01 to cure, repurchase or substitute for a defective
Mortgage Loan constitute the sole remedies of the Purchaser, the
Certificateholders or the Trustee on their behalf respecting a missing or
defective document or a breach of the representations or warranties contained
in this Section 3.01.

          Section 3.02 SELLER REPRESENTATIONS AND WARRANTIES. The Seller

equitable remedies, (2) general equity principals (regardless of whether such
enforcement is considered in a proceeding in equity or at law) or (3) public

policy considerations limit the enforceability of the provisions of this
Agreement which purport to provide indemnification from securities laws
liabilities.

          (iii) The Seller holds all necessary licenses, certificates and
permits from all governmental authorities necessary for conducting its
business as it is presently conducted, except for such licenses, certificates

been obtained or filed, as the case may be, prior to the Closing Date.

          (iv) The execution, delivery and performance of this Agreement by
the Seller will not conflict with or result in a breach of, or constitute a

contract or other agreement to which it is a party or by which it may be
bound.

          (v) No certificate of an officer, written statement or report

any pending insolvency.

          (viii) The Seller is not in violation of, and the execution and
delivery of this Agreement by it and its performance and compliance with the

would materially and adversely affect the Seller's condition (financial or
otherwise) or operations or any of the Seller's properties, or materially and
adversely affect the performance of any of its duties hereunder.

          (ix) There are no actions or proceedings against, or investigations

administrative agency or other tribunal (i) that, if determined adversely,
would prohibit the Seller from entering into this Agreement and the Pooling

validity or enforceability of, this Agreement and the Pooling and Servicing
Agreement.

          (x) The Seller is not transferring the Mortgage Loans to the

<PAGE>

constitute a distribution of any Private Certificate under the Securities Act,
that would render the disposition of any Private Certificate a violation of
Section 5 of the Securities Act or any state securities law, or that would
require registration or qualification pursuant thereto. The Seller will not
sell or otherwise transfer any of the Private Certificates, except in
compliance with the provisions of the Pooling and Servicing Agreement.

          Section 4.01 COVENANTS OF THE SELLER.

          (a) The Seller hereby covenants that except for the transfer
hereunder, the Seller will not sell, pledge, assign or transfer to any other
Person, or grant, create, incur, assume or suffer to exist any lien on any
Mortgage Loan, or any interest therein; the Seller will notify the Trustee, as
assignee of the Purchaser, of the existence of any lien on any Mortgage Loan
immediately upon discovery thereof, and the Seller will defend the right,
title and interest of the Trust, as assignee of the Purchaser, in, to and

or under the Seller; provided, however, that nothing in this Section 4.01
shall prevent or be deemed to prohibit the Seller from suffering to exist upon
any of the Mortgage Loans any liens for municipal or other local taxes and
other governmental charges if such taxes or governmental charges shall not at
the time be due and payable or if the Seller shall currently be contesting the
validity thereof in good faith by appropriate proceedings and shall have set
aside on its books adequate reserves with respect thereto.

          (b) The Seller hereby covenants that neither it nor any affiliate of
the Seller will directly solicit any Mortgagor hereunder to refinance the
related Mortgage Loan. For the purposes of the foregoing, neither the Seller
nor any affiliate of the Seller shall be deemed to directly solicit any

refinancing or if the Mortgagor receives marketing materials which are
generally disseminated.

          Section 7.01 AMENDMENT. This Agreement may be amended from time to
time by the Seller and the Purchaser, by written agreement signed by the
Seller and the Purchaser.

          Section 7.02. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined
in accordance with such laws.

          Section 7.03 NOTICES. All demands, notices and communications
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered at or mailed by registered mail, postage prepaid,
addressed as follows:

writing by the Seller.

          New York, New York 10017
          Attention: Chris Schiavone

or such other address as may hereafter be furnished to the Seller in writing
by the Purchaser.

          Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be held
invalid for any reason whatsoever, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity
or enforceability of the other provisions of this Agreement.

          Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

          Section 7.06 FURTHER AGREEMENTS. The Purchaser and the Seller each
agree to execute and deliver to the other such additional documents,
instruments or agreements as may be necessary or reasonable and appropriate to
effectuate the purposes of this Agreement or in connection with the issuance
of any Series of Certificates representing interests in the Mortgage Loans.

          Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller,
the Seller will cooperate with the Purchaser in connection with the sale of
any of the securities representing interests in the Mortgage Loans. In that
connection, the Seller will provide to the Purchaser any and all information
and appropriate verification of information, whether through letters of its
auditors and counsel or otherwise, as the Purchaser shall reasonably request
and will provide to the Purchaser such additional representations and
warranties, covenants, opinions of counsel, letters from auditors, and
certificates of public officials or officers of the Seller as are reasonably
required in connection with such transactions and the offering of investment
grade securities rated by the Rating Agencies.

          Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than the pledging of the Mortgage Loans by the Seller to
secure a loan by the Purchaser to the Seller. Accordingly, the parties hereto
each intend to treat the transaction for Federal income tax purposes and all
other purposes as a sale by the Seller and a purchase by the Purchaser of the
Mortgage Loans. The Purchaser will have the right to review the Mortgage Loans
and the related Mortgage Files to determine the characteristics of the
Mortgage Loans which will affect the Federal income tax consequences of owning
the Mortgage Loans and the Seller will cooperate with all reasonable requests
made by the Purchaser in the course of such review.

          Section 7.08 SUCCESSORS AND ASSIGNS; ASSIGNMENT OF THIS AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by
the Seller, the Purchaser and the Trustee. The obligations of the Seller under
this Agreement cannot be assigned or delegated to a third party without the
consent of the Purchaser and which consent

                                      19

<PAGE>

shall be at the Purchaser's sole discretion, except that the Purchaser
acknowledges and agrees that the Seller may assign its obligations hereunder
to any Person into which the Seller is merged or any corporation resulting
from any merger, conversion or consolidation to which the Seller is a party or
any Person succeeding to the business of the Seller. The parties hereto
acknowledge that the Purchaser is acquiring the Mortgage Loans for the purpose
of contributing them to a trust that will issue a series of certificates
representing undivided interests in such Mortgage Loans. As an inducement to
the Purchaser to purchase the Mortgage Loans, the Seller acknowledges and
consents to the assignment by the Purchaser to the Trustee of all of the
Purchaser's rights against the Seller pursuant to this Agreement insofar as
such rights relate to Mortgage Loans transferred to the Trustee and to the
enforcement or exercise of any right or remedy against the Seller pursuant to
this Agreement by the Trustee. Such enforcement of a right or remedy by the
Trustee shall have the same force and effect as if the right or remedy had
been enforced or exercised by the Purchaser directly.

          Section 7.09 SURVIVAL. The representations and warranties set forth
in Sections 3.01 and 3.02 hereof shall survive the purchase of the Mortgage
Loans hereunder.

          IN WITNESS WHEREOF, the Seller and the Purchaser have caused their
names to be signed to this Mortgage Loan Purchase Agreement by their
respective officers thereunto duly authorized as of the day and year first

STATE OF          )
                  )  ss.:
COUNTY OF         )

          The undersigned, being first duly sworn, deposes and says as
follows:

          1. The undersigned is [an officer of] ______________, the proposed
Transferee of an Ownership Interest in a [Class R and/or Class R-X
Certificates] (the "Certificates") issued pursuant to the Pooling and
Servicing Agreement, (the "Agreement"), relating to the above- referenced
Certificates, among J.P. Morgan Acceptance Corporation I, as depositor,
Credit-Based Asset Servicing and Securitization LLC, as seller, Litton Loan
Servicing LP, as servicer and U.S. Bank National Association, as trustee.
Capitalized terms used, but not defined herein shall have the meanings
ascribed to such terms in the Agreement. The Transferee has authorized the
undersigned to make this affidavit on behalf of the Transferee.

          2. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificates either (i) for its own account or (ii)
as nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit.
The Transferee has no knowledge that any such affidavit is false.

          3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificates to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability
for the tax if the subsequent Transferee furnished to such Person an affidavit
that such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

          4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificates if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the
pass-through entity does not have actual knowledge that such affidavit is
false. (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 and, except as may be
provided in Treasury Regulations, persons holding interests in pass-through
entities as a nominee for another Person.)

          5. The Transferee has reviewed the provisions of Section 5.02(d) of
the Agreement and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificates including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by
and to abide by the provisions of Section 5.02(d) of the Agreement and the
restrictions noted on the face of the Certificates. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

          6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in
the Certificates, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth in this Exhibit K to the Agreement (a "Transferor Certificate")
to the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

          7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect
to the Certificates.

          8. The Transferee's taxpayer identification number is _______.

          9. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

          10. The Transferee is aware that the Certificates may be a
"noneconomic residual interest" within the meaning of proposed Treasury
regulations promulgated pursuant to 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 was to impede the assessment or collection of tax.

          11. The Transferee is not an employee benefit plan that is subject
to ERISA or a plan that is subject to Section 4975 of the Code, nor are we
acting on behalf of such a plan.

          12. The Transferee will not transfer the Certificates, directly or
indirectly, to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.

          13. The Transferee will not cause income from the Certificates to be
attributable to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.

          14. Either

               (a) (i) At the time of the transfer, and at the close of each
          of the Transferee's two fiscal years preceding the Transferee's
          fiscal year of transfer, the Transferee's gross assets for financial
          reporting purposes exceed $100 million and

<PAGE>

          its net assets for financial reporting purposes exceed $10 million.
          For purposes of the preceding sentence, the gross asses and net
          assets of a Transferee do not include any obligation of any Related
          Person, as defined below, or any other asset if a principal purpose
          for holding or acquiring the other asset is to permit the Transferee
          to satisfy the conditions of this paragraph 15(a); (ii) The
          Transferee is an Eligible Corporation, as defined below, and hereby
          agrees that any subsequent transfer of the interest will be to
          another Eligible Corporation in a transaction that satisfies this
          Transfer Affidavit, including this paragraph 15(a); and (iii) The
          Transferee has not given the Transferor any reason to know that the
          Transferee will not honor the restrictions on subsequent transfers
          of the residual interest or that the Transferee will not honor the
          restrictions on subsequent transfers of the residual interest or
          that the Transferee cannot or will not pay any taxes associated with
          the residual interest; or

               (b) (i) The Transferee is a United States Person; (ii) The
          present value of the anticipated tax liabilities associated with
          holding the residual interest does not exceed the sum of: (A) The
          present value of any consideration given to the Transferee to
          acquire the interest; (B) The present value of the expected future
          distributions on the interest; and (C) The present value of the
          anticipated tax savings associated with holding the interest as any
          REMIC generates losses; and (iii) For purposes of calculating the
          aforementioned present values: (A) The Transferee has assumed that
          it pays tax at a rate equal to the highest rate of tax specified in
          Code Section 11(b)(1) (unless the Transferee has been subject to the
          alternative minimum tax under Code Section 55 in the preceding two
          years and will compute its taxable income in the current taxable
          year using the alternative minimum tax rate, in which case the
          Transferee can assume that it pays tax at the rate specified in Code
          Section 55(b)(1)(B) provided the Transferee states in this Transfer
          Affidavit that it is using such alternate rate and that has been
          subject to the alternative minimum tax under Code Section 55 in the
          preceding two years and will compute its taxable income in the
          current taxable year using the alternative minimum tax rate) and (B)
          The Transferee uses a discount rate equal to the Federal short-term
          rate prescribed by section 1274(d) for the month of the transfer and
          the compounding period used by the Transferee.

          The term "Eligible Corporation" means any domestic C corporation (as
defined in Section 1361(a)(2) of the Code) other than a corporation which is
exempt from, or is not subject to, tax under section 11 of the Code, an entity
described in section 851(a) or 856(a) of the Code, a REMIC; or an organization
to which part I, subchapter T, chapter 1, subtitle A of the Code applies. The
Term "Related Person" means any person that bears a relationship to the
Transferee enumerated in section 267(b) or 707(b)(1) of the Code, using "20
percent" instead of "50 percent" where it appears under the provisions; or is
under common control (within the meaning of Section 52(a) and (b) of the Code)
with the Transferee.

Asset-Backed Certificates, Series 2004-CB4 (the "Certificates"), we certify
that (a) we understand that the Certificates have not been registered under
the Securities Act of 1933, as amended (the "Act"), and are being disposed by
us in a transaction that is exempt from the registration requirements of the
Act, (b) we have not offered or sold any Certificates to, or solicited offers
to buy any Certificates from, any person, or otherwise approached or
negotiated with any person with respect thereto, in a manner that would be
deemed, or taken any other action which would result in, a violation of
Section 5 of the Act, (c) [in the case of a Residual Certificate only] to the
extent we are disposing of a Class [R, or R-X] Certificate, we have no
knowledge the Transferee is not a Permitted Transferee and (d) [in the case of
a Residual Certificate only] no purpose of the proposed disposition of a Class
[R, or R-X] Certificate is to impede the assessment or collection of tax.

                                       Very truly yours,
