          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 twelve classes of
certificates, designated as (i) the Class A-1 Certificates, (ii) the Class A-2
Certificates, (iii) the Class M-1 Certificates, (iv) the Class M-2 Certificates,
(v) the Class M-3 Certificates, (vi) the Class M-4 Certificates, (vii) the Class

                                     -------

     As provided herein, the Trustee will make an election to treat the

Account, the Cap Contract and the Master Servicer Prepayment Charge Payment
Amounts) as a real estate 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
following table irrevocably sets forth the designation, the Uncertificated REMIC
1 Pass-Through Rate, the initial Uncertificated Principal Balance, and solely

Servicer, in its capacity as Originator, shall have 120 days to cure such defect
or deliver such missing document to the Trustee or the Custodian. If the

hereof and, to the extent necessary, in Section 2.01(iv) hereof to be recorded.
The Depositor shall be required to deliver such Assignments for recording within

administrative convenience and facilitation of servicing and to reduce closing
costs, the Assignments of Mortgage shall not be required to be submitted for
recording (except with respect to any Mortgage Loan located in Maryland) unless
the Trustee and the Depositor receives notice that such failure to record would
result in a withdrawal or a downgrading by any Rating Agency of the rating on
any Class of Certificates; PROVIDED, HOWEVER, each Assignment shall be submitted
for recording by the Depositor in the manner described above, at no expense to
the Trust Fund or Trustee, upon the earliest to occur of: (i) reasonable

to any one Assignment the occurrence of a bankruptcy, insolvency or foreclosure
relating to the Mortgagor under the related Mortgage, (vi) any Mortgage Loan
that is 90 days or more Delinquent and (vii) reasonable direction by the NIMS
Insurer. Upon (a) receipt of written notice from the Trustee that recording of
the Assignments is required pursuant to one or more of the conditions (excluding
(v) and (vi) above) set forth in the preceding sentence or (b) upon the
occurrence of condition (v) or (vi) in the preceding sentence, the Depositor
shall be required to deliver such Assignments for recording as provided above,
promptly and in any event within 30 days following receipt of such notice.
Notwithstanding the foregoing, if the Originator fails to pay the cost of
recording the Assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust. The Depositor shall
furnish the Trustee, or its designated agent, with a copy of each Assignment
submitted for recording. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Depositor 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. In the event
that any Mortgage Note is endorsed in blank as of the Closing Date (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans), within
ninety (90) days of the Closing Date (or Subsequent Transfer Date, with respect
to Subsequent Mortgage Loans) the Depositor shall cause to be completed such
endorsements "Pay to the order of Wells Fargo Bank Minnesota, National
Association, as Trustee, without recourse."

          The Depositor herewith delivers to the Trustee an executed copy of the
Mortgage Loan Purchase Agreement and the PMI Policy.

          The Master Servicer shall forward to the Custodian original documents
evidencing an assumption, modification, consolidation or extension of any
Mortgage Loan entered into in accordance with this Agreement within two weeks of
their execution; provided, however, that the Master Servicer shall provide the
Custodian with a certified true copy of any such document submitted for
recordation within two weeks of its execution, and shall provide the original of
any document submitted for recordation or a copy of such document certified by
the appropriate public recording office to be a true and complete copy of the
original within 365 days of its submission for recordation. In the event that
the Master Servicer cannot provide a copy of such document certified


                                       55

<PAGE>



by the public recording office within such 365 day period, an Officers'
Certificate of the Master Servicer which shall (A) identify the recorded
document, (B) state that the recorded document has not been delivered to the
Custodian due solely to a delay caused by the public recording office, (C) state
the amount of time generally required by the applicable recording office to
record and return a document submitted for recordation, if known and (D) specify
the date the applicable recorded document is expected to be delivered to the
Custodian, and, upon receipt of a copy of such document certified by the public
recording office, the Master Servicer shall immediately deliver such document to
the Custodian. In the event the appropriate public recording office will not
certify as to the accuracy of such document, the Master Servicer shall deliver a
copy of such document certified by an officer of the Master Servicer to be a
true and complete copy of the original to the Custodian.

          SECTION 2.02. Acceptance by Trustee.

          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 Trustee acknowledges receipt of 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, for the benefit of the Certificateholders, to
review, or that it has reviewed pursuant to Section 2.01 (or to cause the
Custodian to review or that it has caused the Custodian to have reviewed) each
Mortgage File on or prior to the Closing Date, with respect to each Initial
Mortgage Loan or the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof). The Trustee further agrees, for
the benefit of the Certificateholders, to certify to the Depositor, the Master
Servicer and the NIMS Insurer in substantially the form attached hereto as
Exhibit F-1, within 45 days after the Closing Date, with respect to each Initial
Mortgage Loan and the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof) 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 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 and (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) and (2) of the Mortgage
Loan Schedule accurately reflects information set forth in the Mortgage File. 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.



                                       56

          Prior to the first anniversary date of this Agreement the Trustee
shall deliver (or cause the Custodian to deliver) to the Depositor, the Master
Servicer and the NIMS Insurer 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 shall so notify the Originator the
Depositor, the NIMS Insurer and the Master Servicer. In addition, upon the
discovery by the Originator, the Depositor, the NIMS Insurer or the Master
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 Originator
in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which
materially adversely affects such Mortgage Loan or the interests of the related
Certificateholders in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties to this Agreement.

          The Depositor and the Trustee intend that the assignment and transfer
herein contemplated constitute a sale of the Mortgage Loans, the related
Mortgage Notes and the related documents, conveying good title thereto free and
clear of any liens and encumbrances, from the Depositor to the Trustee in trust
for the benefit of the Certificateholders 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 a first
priority perfected security interest in all of the Depositor's right, title and
interest in and to the Mortgage Loans, the related Mortgage Notes 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
                        Originator.

          (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 Originator of any representation, warranty or covenant under
the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which
materially adversely affects the value of such Mortgage Loan or the interest
therein of the Certificateholders, the Trustee shall promptly notify the
Originator, the NIMS Insurer and the Master Servicer of such defect, missing
document or breach and request that the Originator deliver such missing document
or cure such defect or breach within 120 days from the date the Originator was
notified of such missing document, defect or breach, and if the Originator does
not deliver such missing document or cure such defect or breach in all material
respects during such period, the Trustee shall enforce the Originator's
obligation under the Mortgage Loan Purchase Agreement and cause the Originator
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 period, if the
Originator shall have commenced to cure such breach within such 120 day period,
the Originator shall be permitted to proceed thereafter


                                       57

<PAGE>



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 Master Servicer of such
deposit, shall release to the Originator the related Mortgage File and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as the Originator shall furnish to it and as shall be
necessary to vest in the Originator any Mortgage Loan released pursuant hereto
and the Trustee shall have no further responsibility with regard to such
Mortgage File (it being understood that the Trustee shall have no responsibility
for determining the sufficiency of such assignment for its intended purpose). In
lieu of repurchasing any such Mortgage Loan as provided above, the Originator
may cause such Mortgage Loan to be removed from the Trust Fund (in which case it
shall become a Deleted Mortgage Loan) and substitute one or more Qualified
Substitute Mortgage Loans in the manner and subject to the limitations set forth
in Section 2.03(d). It is understood and agreed that the obligation of the
Originator to cure or to repurchase (or to substitute for) any Mortgage Loan as
to which a document is missing, a material defect in a constituent document
exists or as to which such a breach has occurred and is continuing shall
constitute the sole remedy against the Originator respecting such omission,
defect or breach available to the Trustee on behalf of the Certificateholders.

          (b) Within 90 days of the earlier of discovery by the Depositor or
receipt of notice by the Depositor of the breach of any representation, warranty
or covenant of the Depositor set forth in Section 2.06 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Depositor shall cure such breach in all material respects.

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

          (d) Any substitution of Qualified Substitute Mortgage Loans for
Deleted 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 Deleted Mortgage Loan for which the Originator substitutes a Qualified
Substitute Mortgage Loan or Loans, such substitution shall be effected by the
Originator delivering to the Trustee, for such Qualified Substitute Mortgage
Loan or Loans, the Mortgage Note, the Mortgage and the Assignment to the
Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate providing that each such Qualified Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution Adjustment
(as described below), if any, in connection with such substitution. The Trustee
shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans
and, within ten Business Days thereafter, shall review such documents as
specified in Section 2.02 and deliver to the Master Servicer and the NIMS
Insurer, with respect to such Qualified 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 to the Master Servicer and the NIMS
Insurer a certification substantially in the form of Exhibit F-2 hereto with
respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with


                                       58

<PAGE>



respect to Qualified Substitute Mortgage Loans in the month of substitution are
not part of the Trust Fund and will be retained by the Originator. For the month
of substitution, distributions to Certificateholders will reflect the
collections and recoveries in respect of such Deleted Mortgage Loan in the Due
Period preceding the month of substitution and the Originator shall thereafter
be entitled to retain all amounts subsequently received in respect of such
Deleted Mortgage Loan. The Originator shall give or cause to be given written
notice to the Certificateholders and the NIMS Insurer that such substitution has
taken place, shall amend the Mortgage Loan Schedule to reflect the removal of
such Deleted Mortgage Loan from the terms of this Agreement and the substitution
of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of
such amended Mortgage Loan Schedule to the NIMS Insurer and the Trustee. Upon
such substitution by the Originator, such Qualified Substitute Mortgage Loan or
Loans shall constitute part of the Mortgage Pool and shall be subject in all
respects to the terms of this Agreement and the Mortgage Loan Purchase
Agreement, including all applicable representations and warranties thereof
included in the Mortgage Loan Purchase Agreement as of the date of substitution.

          For any month in which the Originator substitutes one or more
Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Master Servicer will determine the amount (the "Substitution Adjustment"), if
any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans
exceeds the aggregate, as to each such Qualified 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 Rate.
On the date of such substitution, the Originator will deliver or cause to be
delivered to the Master Servicer for deposit in the Collection Account an amount
equal to the Substitution Adjustment, if any, and the Trustee, upon receipt of
the related Qualified Substitute Mortgage Loan or Loans and certification by the
Master Servicer of such deposit, shall release to the Originator the related
Mortgage File or Files and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as the Originator shall
deliver to it and as shall be necessary to vest therein any Deleted Mortgage
Loan released pursuant hereto.

          In addition, the Originator shall obtain at its own expense and
deliver to the Trustee and the NIMS Insurer an Opinion of Counsel to the effect
that such substitution will not cause (a) any federal tax to be imposed on 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.

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


                                       59

<PAGE>



Mortgage Loan's status as a non-qualified mortgage is or results from a breach
of any representation, warranty or covenant made by the Originator under the
Mortgage Loan Purchase Agreement or (ii) the Depositor, if the affected Mortgage
Loan's status as a non-qualified mortgage is a breach of any representation or
warranty of the Depositor set forth in Section 2.06, or if its status as a
non-qualified mortgage is a breach of no representation or warranty. Any such
repurchase or substitution shall be made in the same manner as set forth in
Section 2.03(a), if made by the Originator, or Section 2.03(b), if made by the
Depositor. The Trustee shall reconvey to the Depositor or the Originator, as the
case may be, the Mortgage Loan to be released pursuant hereto in the same
manner, and on the same terms and conditions, as it would a Mortgage Loan
repurchased for breach of a representation or warranty.

          SECTION 2.04. Intentionally Omitted.

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

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

          (i) The Master Servicer is 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 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
     Master Servicer or to ensure the enforceability or validity of each
     Mortgage Loan; the Master 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
     Master 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 Master 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 taken by the Master Servicer to
     make this Agreement valid and binding upon the Master 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 Master Servicer and
     will not result in the breach of any term or provision of the charter or
     by-laws of the Master 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 Master Servicer or its
     property is subject, or result in the violation of any law, rule,
     regulation, order, judgment or decree to which the Master Servicer or its
     property is subject;



                                       60

<PAGE>



          (iii) The execution and delivery of this Agreement by the Master
     Servicer and the performance and compliance with its obligations and
     covenants hereunder do not require the consent or approval of any
     governmental authority or, if such consent or approval is required, it has
     been obtained;

          (iv) This Agreement, and all documents and instruments contemplated
     hereby which are executed and delivered by the Master Servicer, constitute
     and will constitute valid, legal and binding obligations of the Master
     Servicer, enforceable in accordance with their respective terms, except as
     the enforcement thereof may be limited by applicable bankruptcy laws and
     general principles of equity;

          (v) [Reserved];

          (vi) The Master Servicer does not believe, nor does it have any reason
     or cause to believe, that it cannot perform each and every covenant
     contained in this Agreement;

          (vii) There is no action, suit, proceeding or investigation pending
     or, to its knowledge, threatened against the Master Servicer that, either
     individually or in the aggregate, (A) may result in any change in the
     business, operations, financial condition, properties or assets of the
     Master Servicer that might prohibit or materially and adversely affect the
     performance by such Master Servicer of its obligations under, or validity
     or enforceability of, this Agreement, or (B) may result in any material
     impairment of the right or ability of the Master Servicer to carry on its
     business substantially as now conducted, or (C) may result in any material
     liability on the part of the Master Servicer, or (D) would draw into
     question the validity or enforceability of this Agreement or of any action
     taken or to be taken in connection with the obligations of the Master
     Servicer contemplated herein, or (E) would otherwise be likely to impair
     materially the ability of the Master Servicer to perform under the terms of
     this Agreement;

          (viii) Neither this Agreement nor any information, certificate of an
     officer, statement furnished in writing or report delivered to the Trustee
     by the Master Servicer in connection with the transactions contemplated
     hereby contains any untrue statement of a material fact;

          (ix) The Master Servicer covenants that its computer and other systems
     used in servicing the Mortgage Loans operate in a manner such that the
     Master Servicer can service the Mortgage Loans in accordance with the terms
     of this Agreement;

          (x) The information set forth in the Prepayment Charge Schedule
     (including the Prepayment Charge Summary attached thereto) is complete,
     true and correct in all material respects on the date or dates when such
     information is furnished and each Prepayment Charge is permissible and
     enforceable in accordance with its terms (except to the extent that the
     enforceability thereof may be limited by bankruptcy, insolvency,
     moratorium, receivership and other similar laws affecting creditor's rights
     generally or the collectibility thereof may be limited due to acceleration
     in connection with a foreclosure) under applicable state law;


                                       61

<PAGE>



          (xi) The Master Servicer will not waive any Prepayment Charge unless
     it is waived in accordance with the standard set forth in Section 3.01; and

          (xii) The Master Servicer has accurately and fully reported, and will
     continue to accurately and fully report, its borrower credit files to each
     of the credit repositories in a timely manner.

          It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee and shall inure to the benefit of the Trustee, the
Depositor and the Certificateholders. Upon discovery by any of the Depositor,
the NIMS Insurer, the Master Servicer, the Originator or the Trustee of a breach
of any of the foregoing representations, warranties and covenants which
materially and adversely affects the value of any Mortgage Loan, Prepayment
Charge or the interests therein of the Certificateholders, the party discovering
such breach shall give prompt written notice (but in no event later than two
Business Days following such discovery) to the Master Servicer, the Originator,
the NIMS Insurer and the Trustee. Notwithstanding the foregoing, within 90 days
of the earlier of discovery by the Master Servicer or receipt of notice by the
Master Servicer of the breach of the representation or covenant of the Master
Servicer (in its capacity as Originator) set forth in Sections 2.05(x) or
2.05(xi) above which materially and adversely affects the interests of the
Holders of the Class P Certificates in any Prepayment Charge, the Master
Servicer shall remedy such breach as follows: (a) if the representation made by
the Master Servicer (in its capacity as Originator) in Section 2.05(x) above is
breached and a Principal Prepayment has occurred in the applicable Prepayment
Period or if a change of law subsequent to the Closing Date limits the
enforceability of a Prepayment Charge (other than in the circumstances provided
in Section 2.05(x) above), the Master Servicer (in its capacity as Originator)
must pay the amount of the scheduled Prepayment Charge, for the benefit of the
Holders of the Class P Certificates, by depositing such amount into the
Collection Account, net of any amount previously collected by the Master
Servicer and paid by the Master Servicer, for the benefit of the Holders of the
Class P Certificates, in respect of such Prepayment Charge; and (b) if any of
the covenants made by the Master Servicer in Section 2.05(xi) above is breached,
the Master Servicer must pay the amount of such waived Prepayment Charge, for
the benefit of the Holders of the Class P Certificates, by depositing such
amount into the Collection Account. The foregoing shall not, however, limit any
remedies available to the Certificateholders, the Depositor or the Trustee on
behalf of the Certificateholders, pursuant to the Mortgage Loan Purchase
Agreement signed by the Master Servicer in its capacity as Originator,
respecting a breach of the representations, warranties and covenants of the
Master Servicer in its capacity as Originator contained in the Mortgage Loan
Purchase Agreement.

          SECTION 2.06. Representations and Warranties of the Depositor.

          The Depositor represents and warrants to the Trust and the Trustee on
behalf of the Certificateholders as follows:

          (i) This Agreement constitutes a legal, valid and binding obligation
     of the Depositor, enforceable against the Depositor in accordance with its
     terms, except as enforceability may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or other similar laws now or
     hereafter in effect affecting the enforcement of


                                       62

<PAGE>



     creditors' rights in general and except as such enforceability may be
     limited by general principles of equity (whether considered in a proceeding
     at law or in equity);

          (ii) Immediately prior to the sale and assignment by the Depositor to
     the Trustee on behalf of the Trust of each Mortgage Loan, the Depositor had
     good and marketable title to each Mortgage Loan (insofar as such title was
     conveyed to it by the Seller) subject to no prior lien, claim,
     participation interest, mortgage, security interest, pledge, charge or
     other encumbrance or other interest of any nature;

          (iii) As of the Closing Date, the Depositor has transferred all right,
     title and interest in the Mortgage Loans to the Trustee on behalf of the
     Trust;

          (iv) The Depositor has not transferred the Mortgage Loans to the
     Trustee on behalf of the Trust with any intent to hinder, delay or defraud
     any of its creditors;

          (v) The Depositor has been duly incorporated and is validly existing
     as a corporation in good standing under the laws of Delaware, with full
     corporate power and authority to own its assets and conduct its business as
     presently being conducted;

          (vi) The Depositor is not in violation of its articles of
     incorporation or by-laws or in default in the performance or observance of
     any material obligation, agreement, covenant or condition contained in any
     contract, indenture, mortgage, loan agreement, note, lease or other
     instrument to which the Depositor is a party or by which it or its
     properties may be bound, which default might result in any material adverse
     changes in the financial condition, earnings, affairs or business of the
     Depositor or which might materially and adversely affect the properties or
     assets, taken as a whole, of the Depositor;

          (vii) The execution, delivery and performance of this Agreement by the
     Depositor, and the consummation of the transactions contemplated thereby,
     do not and will not result in a material breach or violation of any of the
     terms or provisions of, or, to the knowledge of the Depositor, constitute a
     default under, any indenture, mortgage, deed of trust, loan agreement or
     other agreement or instrument to which the Depositor is a party or by which
     the Depositor is bound or to which any of the property or assets of the
     Depositor is subject, nor will such actions result in any violation of the
     provisions of the articles of incorporation or by-laws of the Depositor or,
     to the best of the Depositor's knowledge without independent investigation,
     any statute or any order, rule or regulation of any court or governmental
     agency or body having jurisdiction over the Depositor or any of its
     properties or assets (except for such conflicts, breaches, violations and
     defaults as would not have a material adverse effect on the ability of the
     Depositor to perform its obligations under this Agreement);

          (viii) To the best of the Depositor's knowledge without any
     independent investigation, no consent, approval, authorization, order,
     registration or qualification of or with any court or governmental agency
     or body of the United States or any other jurisdiction is required for the
     issuance of the Certificates, or the consummation by the Depositor of the
     other transactions contemplated by this Agreement, except such consents,
     approvals, authorizations, registrations or qualifications as (a) may be
     required under State securities


                                       63

<PAGE>



     or Blue Sky laws, (b) have been previously obtained or (c) the failure of
     which to obtain would not have a material adverse effect on the performance
     by the Depositor of its obligations under, or the validity or
     enforceability of, this Agreement; and

          (ix) There are no actions, proceedings or investigations pending
     before or, to the Depositor's knowledge, threatened by any court,
     administrative agency or other tribunal to which the Depositor is a party
     or of which any of its properties is the subject: (a) which if determined
     adversely to the Depositor would have a material adverse effect on the
     business, results of operations or financial condition of the Depositor;
     (b) asserting the invalidity of this Agreement or the Certificates; (c)
     seeking to prevent the issuance of the Certificates or the consummation by
     the Depositor of any of the transactions contemplated by this Agreement, as
     the case may be; or (d) which might materially and adversely affect the
     performance by the Depositor of its obligations under, or the validity or
     enforceability of, this Agreement.

          SECTION 2.07. Issuance of Certificates.

          The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Sections 2.01 and 2.02, together with the assignment to it of all other assets
included in the Trust Fund, receipt of which is hereby acknowledged.
Concurrently with such assignment and delivery and in exchange therefor, the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed, authenticated and delivered to or upon the order
of the Depositor, the Certificates in authorized denominations. The interests
evidenced by the Certificates, constitute the entire beneficial ownership
interest in the Trust Fund.

          SECTION 2.08. Conveyance of the Subsequent Mortgage Loans.

          (a) Subject to the conditions set forth in paragraph (b) below in
consideration of the Trustee's delivery on the Subsequent Transfer Dates to or
upon the order of the Depositor of all or a portion of the balance of funds in
the Pre-Funding Accounts, the Depositor shall on any Subsequent Transfer Date
sell, transfer, assign, set over and convey without recourse to the Trust Fund
but subject to the other terms and provisions of this Agreement all of the
right, title and interest of the Depositor in and to (i) the Subsequent Mortgage
Loans identified on the Mortgage Loan Schedule attached to the related
Subsequent Transfer Instrument delivered by the Depositor on such Subsequent
Transfer Date, (ii) all interest accruing thereon on and after the Subsequent
Cut-off Date and all collections in respect of interest and principal due after
the Subsequent Cut-off Date and (iii) all items with respect to such Subsequent
Mortgage Loans to be delivered pursuant to Section 2.01 and the other items in
the related Mortgage Files; PROVIDED, HOWEVER, that the Depositor reserves and
retains all right, title and interest in and to principal received and interest
accruing on the Subsequent Mortgage Loans prior to the related Subsequent
Cut-off Date. The transfer to the Trustee for deposit in the Mortgage Pool by
the Depositor of the Subsequent Mortgage Loans identified on the Mortgage Loan
Schedule shall be absolute and is intended by the Depositor, the Master
Servicer, the Trustee and the Certificateholders to constitute and to be treated
as a sale of the Subsequent Mortgage Loans by the Depositor to the Trust Fund.
The related Mortgage File for each Subsequent Mortgage Loan

related Subsequent Transfer Date.

          The purchase price paid by the Trustee from amounts released from the

     Agreement, to the extent of the Subsequent Mortgage Loans;

          (ix) the Depositor shall have delivered to the Trustee, the

<PAGE>



50.00% by aggregate Principal Balance of the Group I Mortgage Loans; (vi) will
consist of Mortgage Loans with Prepayment Charges representing no less than
70.00% by aggregate Principal Balance of the Group I Mortgage Loans; and (vii)
have no more than 34.50% of Fixed Rate Mortgage Loans by aggregate Principal

Cut-off Date.

          Following the purchase of any Subsequent Group II Mortgage Loan by the

Loans) will: (i) have a weighted average original term to stated maturity of not

33.50% of Fixed Rate Mortgage Loans by aggregate Principal Balance of the Group
II Mortgage Loans. In addition, the Adjustable Rate Group II Mortgage Loans will
have a weighted average Gross Margin not less than 4.500% per annum. For
purposes of the calculations described in this paragraph, percentages of the
Group II Mortgage Loans will be based on the Principal Balance of the Initial
Group II Mortgage Loans as of the Cut-off Date and the Principal Balance of the
Subsequent Group II Mortgage Loans as of the related Subsequent Cut-off Date.

          (e) Notwithstanding the foregoing, any Subsequent Mortgage Loan may be
rejected by (i) the NIMS Insurer or (ii) any Rating Agency if the inclusion of
any such Subsequent Mortgage Loan would adversely affect the ratings of any
Class of Certificates. At least one Business Day prior to the Subsequent
Transfer Date, each Rating Agency shall notify the Trustee as to which
Subsequent Mortgage Loans, if any, shall not be included in the transfer on the
Subsequent Transfer Date; provided, however, that the Master Servicer, in its
capacity as Originator, shall have delivered to each Rating Agency at least
three Business Days prior to such Subsequent Transfer Date a computer file
acceptable to each Rating Agency describing the characteristics specified in
paragraphs (c) and (d) above.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

          SECTION 3.01. Master Servicer to Act as Master Servicer.

          The Master Servicer shall service and administer the Mortgage Loans on
behalf of the Trust and in the best interests of and for the benefit of the
Certificateholders (as determined by the Master Servicer in its reasonable
judgment) in accordance with the terms of this Agreement and the Mortgage Loans
and, to the extent consistent with such terms, in the same manner in which it
services and administers similar mortgage loans for its own portfolio, giving
due consideration to customary and usual standards of practice of mortgage
lenders and loan servicers administering similar mortgage loans but without
regard to:

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

          (B) the ownership or non-ownership of any Certificate by the Master
     Servicer or any Affiliate of the Master Servicer;

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

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

          To the extent consistent with the foregoing, the Master Servicer (a)
shall seek the timely and complete recovery of principal and interest on the
Mortgage Notes and (b) shall waive (or permit a Sub-Servicer to waive) a
Prepayment Charge only under the following circumstances: (i) such waiver is
standard and customary in servicing similar Mortgage Loans and (ii) either (A)
such waiver relates to a default or a reasonably foreseeable default and would,
in the reasonable judgement of the Master Servicer, maximize recovery of total
proceeds taking into account the value of such Prepayment Charge and the related
Mortgage Loan or (B) such waiver is made in connection with a refinancing of the
related Mortgage Loan unrelated to a default or a reasonably foreseeable default
where (x) the related Mortgagor has stated to the Master Servicer or an
applicable Sub- Servicer an intention to refinance the related Mortgage Loan and
(y) the Master Servicer has concluded in its reasonable judgement that the
waiver of such Prepayment Charge would induce such mortgagor to refinance with
the Master Servicer; provided, however, that the Master Servicer shall waive no
more than 5.00% of the Prepayment Charges (by number of Prepayment Charges) set
forth on the Prepayment Charge Schedule in accordance with clause (ii)(B) above.
If a Prepayment Charge is waived as permitted by meeting the standards described
in clauses (i) and (ii)(B) above, then the Master Servicer is required to pay
the amount of such waived Prepayment Charge, for the benefit of the Holders of
the Class P Certificates, by depositing such amount into the Collection Account
together with and at the time that the amount prepaid on the related Mortgage
Loan is


                                       70

<PAGE>



required to be deposited into the Collection Account. Notwithstanding any other
provisions of this Agreement, any payments made by the Master Servicer in
respect of any waived Prepayment Charges pursuant to clauses (i) and (ii)(B)
above shall be deemed to be paid outside of the Trust Fund. Subject only to the
above-described servicing standards and the terms of this Agreement and of the
Mortgage Loans, the Master Servicer shall have full power and authority, acting
alone or through Sub-Servicers as provided in Section 3.02, to do or cause to be
done any and all things in connection with such servicing and administration
which it may deem necessary or desirable. Without limiting the generality of the
foregoing, the Master Servicer in its own name or in the name of a Sub-Servicer
is hereby authorized and empowered by the Trustee when the Master Servicer
believes it appropriate in its best judgment in accordance with the servicing
standards set forth above, to execute and deliver, on behalf of the
Certificateholders and the Trustee, and upon notice to the Trustee, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge, and all other comparable instruments, with respect to the Mortgage
Loans and the Mortgaged Properties and to institute foreclosure proceedings or
obtain a deed-in-lieu of foreclosure so as to convert the ownership of such
properties, and to hold or cause to be held title to such properties, on behalf
of the Trustee and Certificateholders. The Master Servicer shall service and
administer the Mortgage Loans in accordance with applicable state and federal
law and shall provide to the Mortgagors any reports required to be provided to
them thereby. The Master Servicer shall also comply in the performance of this
Agreement with all reasonable rules and requirements of each insurer under any
standard hazard insurance policy. Subject to Section 3.17, within 15 days of the
Closing Date, the Trustee shall execute, at the written request of the Master
Servicer, and furnish to the Master Servicer and any Sub-Servicer any special or
limited powers of attorney for each county in which a Mortgaged Property is
located and other documents necessary or appropriate to enable the Master
Servicer or any Sub-Servicer to carry out their servicing and administrative
duties hereunder; PROVIDED, such limited powers of attorney or other documents
shall be prepared by the Master Servicer and submitted to the Trustee for
execution. The Trustee shall not be liable for the actions of the Master
Servicer or any Sub-Servicers under such powers of attorney.

          Subject to Section 3.09 hereof, in accordance with the standards of
the preceding paragraph, the Master Servicer shall advance or cause to be
advanced funds as necessary for the purpose of effecting the timely payment of
taxes and assessments on the Mortgaged Properties, which advances shall be
Servicing Advances reimbursable in the first instance from related collections
from the Mortgagors pursuant to Section 3.09, and further as provided in Section
3.11. Any cost incurred by the Master Servicer or by Sub-Servicers in effecting
the timely payment of taxes and assessments on a Mortgaged Property shall not,
for the purpose of calculating distributions to Certificateholders, be added to
the unpaid Principal Balance of the related Mortgage Loan, notwithstanding that
the terms of such Mortgage Loan so permit.

          Notwithstanding anything in this Agreement to the contrary, the Master
Servicer may not make any future advances with respect to a Mortgage Loan
(except as provided in Section 4.04) and the Master Servicer shall not (i)
permit any modification with respect to any Mortgage Loan that would change the
Mortgage Rate, reduce or increase the Principal Balance (except for reductions
resulting from actual payments of principal) or change the final maturity date
on such Mortgage Loan (unless, as provided in Section 3.07, the Mortgagor is in
default with respect to the Mortgage Loan or such default is, in the judgment of
the Master Servicer, reasonably foreseeable) or (ii) permit any modification,
waiver or amendment of any term of any Mortgage Loan that would both (A) effect


                                       71

<PAGE>



an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code
(or Treasury regulations promulgated thereunder) and (B) cause any REMIC created
hereunder to fail to qualify as a REMIC under the Code or the imposition of any
tax on "prohibited transactions" or "contributions after the startup date" under
the REMIC Provisions.

          SECTION 3.02. Sub-Servicing Agreements Between Master Servicer and
                        Sub-Servicers.

          (a) The Master Servicer may enter into Sub-Servicing Agreements with
Sub-Servicers for the servicing and administration of the Mortgage Loans;
PROVIDED, HOWEVER, that (i) such agreements would not result in a withdrawal or
a downgrading by any Rating Agency of the rating on any Class of Certificates
and (ii) the NIMS Insurer shall have consented to such Sub- Servicing Agreement.
The Trustee is hereby authorized to acknowledge, at the request of the Master
Servicer, any Sub-Servicing Agreement that meets the requirements applicable to
Sub-Servicing Agreements set forth in this Agreement and that is otherwise
permitted under this Agreement.

          Each Sub-Servicer shall be (i) authorized to transact business in the
state or states where the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law to enable the
Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing
Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each
Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming
to the provisions set forth in Section 3.08 and provide for servicing of the
Mortgage Loans consistent with the terms of this Agreement. The Master Servicer
will examine each Sub-Servicing Agreement and will be familiar with the terms
thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with
any of the provisions of this Agreement. The Master Servicer and the
Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements
or enter into different forms of Sub-Servicing Agreements; PROVIDED, HOWEVER,
that any such amendments or different forms shall be consistent with and not
violate the provisions of this Agreement, and that no such amendment or
different form shall be made or entered into which could be reasonably expected
to be materially adverse to the interests of the Certificateholders without the
consent of the Holders of Certificates entitled to at least 66% of the Voting
Rights; PROVIDED, FURTHER, that the consent of the Holders of Certificates
entitled to at least 66% of the Voting Rights shall not be required (i) to cure
any ambiguity or defect in a Sub-Servicing Agreement, (ii) to correct, modify or
supplement any provisions of a Sub-Servicing Agreement, or (iii) to make any
other provisions with respect to matters or questions arising under a
Sub-Servicing Agreement, which, in each case, shall not be inconsistent with the
provisions of this Agreement. Any variation without the consent of the Holders
of Certificates entitled to at least 66% of the Voting Rights from the
provisions set forth in Section 3.08 relating to insurance or priority
requirements of Sub-Servicing Accounts, or credits and charges to the
Sub-Servicing Accounts or the timing and amount of remittances by the
Sub-Servicers to the Master Servicer, are conclusively deemed to be inconsistent
with this Agreement and therefore prohibited. The Master Servicer shall deliver
to the NIMS Insurer and the Trustee copies of all Sub-Servicing Agreements, and
any amendments or modifications thereof, promptly upon the Master Servicer's
execution and delivery of such instruments.

          (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Sub-Servicer


                                       72

<PAGE>



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

          SECTION 3.03. Successor Sub-Servicers.

          The Master Servicer, with the consent of the NIMS Insurer, shall be
entitled to terminate any Sub-Servicing Agreement and the rights and obligations
of any Sub-Servicer pursuant to any Sub-Servicing Agreement in accordance with
the terms and conditions of such Sub-Servicing Agreement. In the event of
termination of any Sub-Servicer, all servicing obligations of such Sub- Servicer
shall be assumed simultaneously by the Master Servicer without any act or deed
on the part of such Sub-Servicer or the Master Servicer, and the Master Servicer
either shall service directly the related Mortgage Loans or shall enter into a
Sub-Servicing Agreement with a successor Sub-Servicer which qualifies under
Section 3.02.

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

          SECTION 3.04. Liability of the Master Servicer.

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

          SECTION 3.05. No Contractual Relationship Between Sub-Servicers and
                        the NIMS Insurer, the Trustee or Certificateholders.

          Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Master Servicer alone, and the NIMS Insurer, the Trustee or Certificateholders
shall not be deemed parties thereto and shall have no claims, rights,
obligations, duties or liabilities with respect to the Sub-Servicer except as
set forth in Section 3.06. The Master Servicer shall be solely liable for all
fees owed by it to any Sub-Servicer, irrespective of whether the Master
Servicer's compensation pursuant to this Agreement is sufficient to pay such
fees.

          SECTION 3.06. Assumption or Termination of Sub-Servicing Agreements by
                        Trustee.

          In the event the Master Servicer shall for any reason no longer be the
servicer (including by reason of the occurrence of a Master Servicer Event of
Termination), the Trustee shall thereupon assume all of the rights and
obligations of the Master Servicer under each Sub-Servicing Agreement that the
Master Servicer may have entered into, unless the Trustee elects to terminate
any Sub-Servicing Agreement in accordance with its terms as provided in Section
3.03. Upon such assumption, the Trustee (or the successor servicer appointed
pursuant to Section 7.02) shall be deemed, subject to Section 3.03, to have
assumed all of the departing Master Servicer's interest therein and to have
replaced the departing Master Servicer as a party to each Sub-Servicing
Agreement to the same extent as if each Sub-Servicing Agreement had been
assigned to the assuming party, except that (i) the departing Master Servicer
shall not thereby be relieved of any liability or obligations under any
Sub-Servicing Agreement that arose before it ceased to be the Master Servicer
and (ii) neither the Trustee nor any successor Master Servicer shall be deemed
to have assumed any liability or obligation of the Master Servicer that arose
before it ceased to be the Master Servicer.

          The Master Servicer at its expense shall, upon request of Trustee,
deliver to the assuming party all documents and records relating to each
Sub-Servicing Agreement and the Mortgage Loans then being serviced and an
accounting of amounts collected and held by or on behalf of it, and otherwise
use its best efforts to effect the orderly and efficient transfer of the Sub-
Servicing Agreements to the assuming party. All Servicing Transfer Costs shall
be paid by the predecessor Master Servicer upon presentation of reasonable
documentation of such costs, and if such predecessor Master Servicer defaults in
its obligation to pay such costs, such costs shall be paid by the successor
Master Servicer or the Trustee (in which case the successor Master Servicer or
the Trustee, as applicable, shall be entitled to reimbursement therefor from the
assets of the Trust).

          SECTION 3.07. Collection of Certain Mortgage Loan Payments.

          The Master Servicer shall make reasonable efforts to collect all
payments called for under the terms and provisions of the Mortgage Loans, and
shall, to the extent such procedures shall be consistent with this Agreement and
the terms and provisions of any applicable insurance policies, follow such
collection procedures as it would follow with respect to mortgage loans
comparable to


                                       74

<PAGE>



the Mortgage Loans and held for its own account. Consistent with the foregoing,
the Master Servicer may in its discretion (i) waive any late payment charge or,
if applicable, any penalty interest, or (ii) extend the due dates for the
Monthly Payments due on a Mortgage Note for a period of not greater than 180
days; PROVIDED, HOWEVER, that any extension pursuant to clause (ii) above shall
not affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below; provided further that the NIMS
Insurer's prior written consent shall be required for any modification, waiver
or amendment if the aggregate number of outstanding Mortgage Loans which have
been modified, waived or amended exceeds 5% of the number of Mortgage Loans as
of the Cut-off Date and any Subsequent Cut-off Date. In the event of any such
arrangement pursuant to clause (ii) above, the Master Servicer shall make timely
advances on such Mortgage Loan during such extension pursuant to Section 4.04
and in accordance with the amortization schedule of such Mortgage Loan without
modification thereof by reason of such arrangement. Notwithstanding the
foregoing, in the event that any Mortgage Loan is in default or, in the judgment
of the Master Servicer, such default is reasonably foreseeable, the Master
Servicer, consistent with the standards set forth in Section 3.01, may also
waive, modify or vary any term of such Mortgage Loan (including modifications
that would change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of such Mortgage Loan), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of such Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor (any and all such waivers, modifications, variances,
forgiveness of principal or interest, postponements, or indulgences collectively
referred to herein as "forbearance"), PROVIDED, HOWEVER, that in no event shall
the Master Servicer grant any such forbearance (other than as permitted by the
second sentence of this Section) with respect to any one Mortgage Loan more than
once in any 12 month period or more than three times over the life of such
Mortgage Loan, and PROVIDED, FURTHER, that in determining which course of action
permitted by this sentence it shall pursue, the Master Servicer shall adhere to
the Loss Mitigation Procedures. The Master Servicer's analysis supporting any
forbearance and the conclusion that any forbearance meets the standards of
Section 3.01 and the Loss Mitigation Procedures shall be reflected in writing in
the Mortgage File.

          SECTION 3.08. Sub-Servicing Accounts.

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


                                       75

          SECTION 3.09. Collection of Taxes, Assessments and Similar Items;
                        Servicing Accounts.

          The Master Servicer shall establish and maintain, or cause to be
established and maintained, one or more accounts (the "Servicing Accounts"),
into which all Escrow Payments shall be deposited and retained. Servicing
Accounts shall be Eligible Accounts. The Master Servicer shall deposit in the
clearing account in which it customarily deposits payments and collections on
mortgage loans in connection with its mortgage loan servicing activities on a
daily basis, and in no event more than one Business Day after the Master
Servicer's receipt thereof, all Escrow Payments collected on account of the
Mortgage Loans and shall thereafter deposit such Escrow Payments in the
Servicing Accounts, in no event more than two Business Days after the receipt of
such Escrow Payments, all Escrow Payments collected on account of the Mortgage
Loans for the purpose of effecting the timely payment of any such items as
required under the terms of this Agreement. Withdrawals of amounts from a
Servicing Account may be made only to (i) effect payment of taxes, assessments,
hazard insurance premiums, and comparable items in a manner and at a time that
assures that the lien priority of the Mortgage is not jeopardized (or, with
respect to the payment of taxes, in a manner and at a time that avoids the loss
of the Mortgaged Property due to a tax sale or the foreclosure as a result of a
tax lien); (ii) reimburse the Master Servicer (or a Sub-Servicer to the extent
provided in the related Sub-Servicing Agreement) out of related collections for
any Servicing Advances made pursuant to Section 3.01 (with respect to taxes and
assessments) and Section 3.14 (with respect to hazard insurance); (iii) refund
to Mortgagors any sums as may be determined to be overages; (iv) pay interest,
if required and as described below, to Mortgagors on balances in the Servicing
Account; or (v) clear and terminate the Servicing Account at the termination of
the Master Servicer's obligations and responsibilities in respect of the
Mortgage Loans under this Agreement in accordance with Article X. In the event
the Master Servicer shall deposit in a Servicing Account any amount not required
to be deposited therein, it may at any time withdraw such amount from such
Servicing Account, any provision herein to the contrary notwithstanding. The
Master Servicer will be responsible for the administration of the Servicing
Accounts and will be obligated to make Servicing Advances to such accounts when
and as necessary to avoid the lapse of insurance coverage on the Mortgaged
Property, or which the Master Servicer knows, or in the exercise of the required
standard of care of the Master Servicer hereunder should know, 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. If any such payment has not been made and the Master
Servicer receives notice of a tax lien with respect to the Mortgage being
imposed, the Master Servicer will, within 10 business days of such notice,
advance or cause to be advanced funds necessary to discharge such lien on the
Mortgaged Property. As part of its servicing duties, the Master Servicer or
Sub-Servicers shall pay to the Mortgagors interest on funds in the Servicing
Accounts, to the extent required by law and, to the extent that interest earned
on funds in the Servicing Accounts is insufficient, to pay such interest from
its or their own funds, without any reimbursement therefor. The Master Servicer
may pay to itself any excess interest on funds in the Servicing Accounts, to the
extent such action is in conformity with the Servicing Standard, is permitted by
law and such amounts are not required to be paid to Mortgagors or used for any
of the other purposes set forth above.

          SECTION 3.10. Collection Account and Distribution Account.

          (a) On behalf of the Trust Fund, the Master Servicer shall establish
and maintain, or cause to be established and maintained, one or more accounts
(such account or accounts, the "Collection Account"), held in trust for the
benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund,
the Master Servicer shall deposit or cause to be deposited in the clearing
account in which it customarily deposits payments and collections on mortgage
loans in connection with its mortgage loan servicing activities on a daily
basis, and in no event more than one Business Day after the Master Servicer's
receipt thereof, and shall thereafter deposit in the Collection Account, in no
event more than two Business Days after the Master Servicer's receipt thereof,
as and when received or as otherwise required hereunder, the following payments
and collections received or made by it subsequent to the Cut-off Date or
Subsequent Cut-off Date, as applicable, (other than in respect of principal or
interest on the Mortgage Loans due on or before the Cut-off Date or Subsequent
Cut-off Date, as applicable) or payments (other than Principal Prepayments)
received by it on or prior to the Cut-off Date or Subsequent Cut-off Date, as
applicable, but allocable to a Due Period subsequent thereto:

          (i) all payments on account of principal, including Principal
     Prepayments (but not Prepayment Charges), on the Mortgage Loans;

          (ii) all payments on account of interest (net of the related Servicing
     Fee) on each Mortgage Loan;

          (iii) all Insurance Proceeds, Liquidation Proceeds and condemnation
     proceeds (other than proceeds collected in respect of any particular REO
     Property and amounts paid in connection with a purchase of Mortgage Loans
     and REO Properties pursuant to Section 10.01);

          (iv) any amounts required to be deposited pursuant to Section 3.12 in
     connection with any losses realized on Permitted Investments with respect
     to funds held in the Collection Account;

          (v) any amounts required to be deposited by the Master Servicer
     pursuant to the second paragraph of Section 3.14(a) in respect of any
     blanket policy deductibles;

          (vi) all proceeds of any Mortgage Loan repurchased or purchased in
     accordance with Section 2.03 or Section 10.01;

          (vii) all amounts required to be deposited in connection with
     Substitution Adjustments pursuant to Section 2.03;

          (viii) all Prepayment Charges collected by the Master Servicer and any
     Master Servicer Prepayment Charge Payment Amounts in connection with the
     Principal Prepayment of any of the Mortgage Loans; and

          (ix) without duplication, all payments of claims under the PMI Policy.


                                       77

<PAGE>



          The foregoing requirements for deposit in the Collection Account shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of Servicing Fees, late
payment charges, assumption fees, insufficient funds charges and ancillary
income (other than Prepayment Charges) need not be deposited by the Master
Servicer in the Collection Account and may be retained by the Master Servicer as
additional compensation. In the event the Master Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from the Collection Account, any provision herein
to the contrary notwithstanding.

          (b) On behalf of the Trust Fund, 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 Trustee and the
Certificateholders. On behalf of the Trust Fund, the Master Servicer shall
deliver to the Trustee in immediately available funds for deposit in the
Distribution Account on or before 1:00 p.m. New York time (i) on the Master
Servicer Remittance Date, that portion of the Available Funds (calculated
without regard to the references in the definition thereof to amounts that may
be withdrawn from the Distribution Account) for the related Distribution Date
then on deposit in the Collection Account, the amount of all Prepayment Charges
collected during the applicable Prepayment Period by the Master Servicer and
Master Servicer Prepayment Charge Payment Amounts in connection with the
Principal Prepayment of any of the Mortgage Loans then on deposit in the
Collection Account and the amount of any funds reimbursable to an Advancing
Person pursuant to Section 3.29, and (ii) on each Business Day as of the
commencement of which the balance on deposit in the Collection Account exceeds
$75,000 following any withdrawals pursuant to the next succeeding sentence, the
amount of such excess, but only if the Collection Account constitutes an
Eligible Account solely pursuant to clause (ii) of the definition of "Eligible
Account." If the balance on deposit in the Collection Account exceeds $75,000 as
of the commencement of business on any Business Day and the Collection Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of "Eligible Account," the Master Servicer shall, on or before 1:00 p.m. New
York time on such Business Day, withdraw from the Collection Account any and all
amounts payable or reimbursable to the Master Servicer, the Trustee, the
Originator or any Sub-Servicer pursuant to Section 3.11 and shall pay such
amounts to the Persons entitled thereto.

          (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 3.12. The Master Servicer shall give notice to the NIMS Insurer and
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 NIMS Insurer, the Master Servicer and the Depositor of the location of the
Distribution Account when established and prior to any change thereof.

          (d) Funds held in the Collection Account at any time may be delivered
by the Master Servicer to the Trustee for deposit in an account (which may be
the Distribution Account and must satisfy the standards for the Distribution
Account as set forth in the definition thereof) and for all purposes of this
Agreement shall be deemed to be a part of the Collection Account; PROVIDED,
HOWEVER, that the Trustee shall have the sole authority to withdraw any funds
held pursuant to this subsection (d). In the event the Master Servicer shall
deliver to the Trustee for deposit in the Distribution Account any amount not
required to be deposited therein, it may at any time request that the Trustee
withdraw such amount from the Distribution Account and remit to it any such
amount,


                                       78

<PAGE>



any provision herein to the contrary notwithstanding. In addition, the Master
Servicer, with respect to items (i) through (iv) below, shall deliver to the
Trustee from time to time for deposit, and the Trustee, with respect to items
(i) through (iv) below, shall so deposit, in the Distribution Account:

          (i)  any Advances, as required pursuant to Section 4.04;

          (ii) any amounts required to be deposited pursuant to Section 3.23(d)
          or (f) in connection with any REO Property;

          (iii) any amounts to be paid in connection with a purchase of Mortgage
          Loans and REO Properties pursuant to Section 10.01;

          (iv) any Compensating Interest to be deposited pursuant to Section
          3.24 in connection with any Prepayment Interest Shortfall; and

          (v) any amounts required to be paid to the Trustee pursuant to the
          Agreement, including, but not limited to Section 3.06 and Section
          7.02.

          (e) [Reserved].

          (f) The Master Servicer shall deposit in the Collection Account any
amounts required to be deposited pursuant to Section 3.12(b) in connection with
losses realized on Permitted Investments with respect to funds held in the
Collection Account.

          SECTION 3.11. Withdrawals from the Collection Account and Distribution
                        Account.

          (a) The Master Servicer shall, from time to time, make withdrawals
from the Collection Account for any of the following purposes or as described in
Section 4.04:

          (i) to remit to the Trustee for deposit in the Distribution Account
     the amounts required to be so remitted pursuant to Section 3.10(b) or
     permitted to be so remitted pursuant to the first sentence of Section
     3.10(d);

          (ii) subject to Section 3.16(d), to reimburse the Master Servicer for
     (a) any unreimbursed Advances to the extent of amounts received which
     represent Late Collections (net of the related Servicing Fees) of Monthly
     Payments, Liquidation Proceeds and Insurance Proceeds on Mortgage Loans
     with respect to which such Advances were made in accordance with the
     provisions of Section 4.04; (b) any unreimbursed Advances with respect to
     the final liquidation of a Mortgage Loan that are Nonrecoverable Advances,
     but only to the extent that Late Collections, Liquidation Proceeds and
     Insurance Proceeds received with respect to such Mortgage Loan are
     insufficient to reimburse the Master Servicer for such unreimbursed
     Advances; or (c) subject to Section 4.04(b), any unreimbursed Advances to
     the extent of funds held in the Collection Account for future distribution
     that were not included in Available Funds for the preceding Distribution
     Date;



                                       79

<PAGE>



          (iii) subject to Section 3.16(d), to pay the Master Servicer or any
     Sub-Servicer (a) any unpaid Servicing Fees, (b) any unreimbursed Servicing
     Advances with respect to each Mortgage Loan, but only to the extent of any
     Late Collections, Liquidation Proceeds, Insurance Proceeds and condemnation
     proceeds received with respect to such Mortgage Loan, and (c) any Servicing
     Advances with respect to the final liquidation of a Mortgage Loan that are
     Nonrecoverable Advances, but only to the extent that Late Collections,
     Liquidation Proceeds and Insurance Proceeds received with respect to such
     Mortgage Loan are insufficient to reimburse the Master Servicer or any
     Sub-Servicer for Servicing Advances;

          (iv) to pay to the Master Servicer as servicing compensation (in
     addition to the Servicing Fee) on the Master Servicer Remittance Date any
     interest or investment income earned on funds deposited in the Collection
     Account;

          (v) to pay to the Originator, with respect to each Mortgage Loan that
     has previously been purchased or replaced pursuant to Section 2.03 or
     Section 3.16(c) all amounts received thereon subsequent to the date of
     purchase or substitution, as the case may be;

          (vi) to reimburse the Master Servicer for any Advance or Servicing
     Advance previously made which the Master Servicer has determined to be a
     Nonrecoverable Advance in accordance with the provisions of Section 4.04;

          (vii) to pay, or to reimburse the Master Servicer for Servicing
     Advances in respect of, expenses incurred in connection with any Mortgage
     Loan pursuant to Section 3.16(b);

          (viii) to reimburse the Master Servicer for expenses incurred by or
     reimbursable to the Master Servicer pursuant to Section 6.03;

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

          (ix) to pay itself any Prepayment Interest Excess; and

          (x) to clear and terminate the Collection Account pursuant to Section
     10.01.

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



                                       80

<PAGE>



          The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account, to the extent held by or on behalf of
it, pursuant to subclauses (ii), (iii), (iv), (v), (vi) and (vii) above. The
Master Servicer shall provide written notification to the NIMS Insurer and the
Trustee, on or prior to the next succeeding Master Servicer Remittance Date,
upon making any withdrawals from the Collection Account pursuant to subclause
(vi) above; PROVIDED that an Officers' Certificate in the form described under
Section 4.04(d) shall suffice for such written notification to the Trustee in
respect hereof.

          (b) The Trustee shall, from time to time, make withdrawals from the
Distribution Account, for any of the following purposes, without priority:

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

          (ii) to pay itself the Trustee Fee and any other amounts owed to it
     pursuant to Section 8.05;

          (iii) to pay any amounts in respect of taxes pursuant to Section
     9.01(g);

          (iv) to clear and terminate the Distribution Account pursuant to
     Section 10.01;

          (v) to pay any amounts required to be paid to the Trustee pursuant to
     this Agreement, including but not limited to funds required to be paid
     pursuant to Section 3.06 and Section 7.02;

          (vi) to pay to the Trustee, any interest or investment income earned
     on funds deposited in the Distribution Account;

          (vii) to pay to an Advancing Person reimbursements for Advances and/or
     Servicing Advances pursuant to Section 3.29; and

          (viii) to pay the PMI Insurer the PMI Insurer Fee.

          SECTION 3.12. Investment of Funds in the Collection Account and the
                        Distribution Account.

          (a) The Master Servicer may direct any depository institution
maintaining the Collection Account to invest the funds on deposit in such
accounts, and the Trustee may invest the funds on deposit in the Distribution
Account (each such account, for the purposes of this Section 3.12 an "Investment
Account"). All investments pursuant to this Section 3.12 shall be 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 or if such investment is managed or advised by a Person other
than the Trustee or an Affiliate of the Trustee, 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


                                       81

<PAGE>



or if such investment is managed or advised by the Trustee or any Affiliate. All
such Permitted Investments shall be held to maturity, unless payable on demand.
Any investment of funds in an Investment Account shall be made in the name of
the Trustee (in its capacity as such), or in the name of a nominee of the
Trustee. The Trustee shall be entitled to sole possession (except with respect
to investment direction of funds held in the Collection Account and any income
and gain realized thereon) over each such investment, 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:

          (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
deposited in the Collection Account and any REO Account held by or on behalf of
the Master Servicer shall be for the benefit of the Master Servicer and shall be
subject to its withdrawal in accordance with Section 3.11 or Section 3.23, as
applicable. The Master Servicer shall deposit in the Collection Account or any
REO Account, as applicable, the amount of any loss of principal incurred in
respect of any such Permitted Investment made with funds in such account
immediately upon realization of such loss.

          (c) All income and gain realized from the investment of funds
deposited in the Distribution Account shall be for the benefit of the Trustee.
The Trustee shall deposit in the Distribution Account the amount of any loss of
principal incurred in respect of any such Permitted Investment made with funds
in such accounts immediately upon realization of such loss. Permitted Investment
made with funds in such accounts immediately upon realization of such loss.

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

          SECTION 3.13. [Reserved].

          SECTION 3.14. Maintenance of Hazard Insurance and Errors and Omissions
                        and Fidelity Coverage.

          (a) The Master Servicer shall cause to be maintained for each Mortgage
Loan hazard insurance with extended coverage on the Mortgaged Property in an
amount which is at least equal to the lesser of (i) the current Principal
Balance of such Mortgage Loan and (ii) the amount necessary to fully compensate
for any damage or loss to the improvements that are a part of such property on a
replacement cost basis, in each case in an amount not less than such amount as
is necessary to avoid the application of any coinsurance clause contained in the
related hazard insurance policy. The Master Servicer shall also cause to be
maintained hazard insurance with extended coverage on each REO Property in an
amount which is at least equal to the lesser of (i) the maximum insurable value
of the improvements which are a part of such property and (ii) the outstanding
Principal Balance of the related Mortgage Loan at the time it became an REO
Property. The Master Servicer will comply in the performance of this Agreement
with all reasonable rules and requirements of each insurer under any such hazard
policies. Any amounts to be collected by the Master Servicer under any such
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or amounts to be released to the
Mortgagor in accordance with the procedures that the Master Servicer would
follow in servicing loans held for its own account, subject to the terms and
conditions of the related Mortgage and Mortgage Note) shall be deposited in the
Collection Account, subject to withdrawal pursuant to Section 3.11, if received
in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal
pursuant to Section 3.23, if received in respect of an REO Property. Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the purpose of calculating distributions to Certificateholders, be added to the
unpaid Principal Balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit. It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
other than pursuant to such applicable laws and regulations as shall at any time
be in force and as shall require such additional insurance. If the Mortgaged
Property or REO Property is at any time in an area identified in the Federal
Register by the Federal Emergency Management Agency as having special flood
hazards and flood insurance has been made available, the Master Servicer will
cause to be maintained a flood insurance policy in respect thereof. Such flood
insurance shall be in an amount equal to the lesser of (i) the unpaid Principal
Balance of the related Mortgage Loan and (ii) the maximum amount of such
insurance available for the related Mortgaged Property under the national flood
insurance program (assuming that the area in which such Mortgaged Property is
located is participating in such program).

          In the event that the Master Servicer shall obtain and maintain a
blanket policy with an insurer having a General Policy Rating of B:III or better
in Best's Key Rating Guide (or such other rating that is comparable to such
rating) insuring against hazard losses on all of the Mortgage Loans, it shall
conclusively be deemed to have satisfied its obligations as set forth in the
first two sentences of this Section 3.14, it being understood and agreed that
such policy may contain a deductible clause, in which case the Master Servicer
shall, in the event that there shall not have been maintained on the related
Mortgaged Property or REO Property a policy complying with the first two
sentences of this Section 3.14, and there shall have been one or more losses
which would have been covered by such policy, deposit to the Collection Account
from its own funds the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with


                                       83

<PAGE>



its activities as administrator and servicer of the Mortgage Loans, the Master
Servicer agrees to prepare and present, on behalf of itself, the Trustee and
Certificateholders, claims under any such blanket policy in a timely fashion in
accordance with the terms of such policy.

          (b) The Master Servicer shall keep in force during the term of this
Agreement a policy or policies of insurance covering errors and omissions for
failure in the performance of the Master Servicer's obligations under this
Agreement, which policy or policies shall be in such form and amount that would
meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of
the Mortgage Loans, unless the Master Servicer has obtained a waiver of such
requirements from Fannie Mae or Freddie Mac. The Master Servicer shall provide
the Trustee and the NIMS Insurer, upon request, with copies of such insurance
policies and fidelity bond. The Master Servicer shall also maintain a fidelity
bond in the form and amount that would meet the requirements of Fannie Mae or
Freddie Mac, unless the Master Servicer has obtained a waiver of such
requirements from Fannie Mae or Freddie Mac. The Master Servicer shall be deemed
to have complied with this provision if an Affiliate of the Master Servicer has
such errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Master Servicer. Any such errors and omissions policy and fidelity bond
shall by its terms not be cancelable without thirty days' prior written notice
to the Trustee and the NIMS Insurer. The Master Servicer shall also cause each
Sub-Servicer to maintain a policy of insurance covering errors and omissions and
a fidelity bond which would meet such requirements.

          SECTION 3.15. Enforcement of Due-On-Sale Clauses; Assumption
                        Agreements.

          The Master Servicer will, to the extent it has knowledge of any
conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor
(whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains or is to remain liable under the Mortgage Note and/or the
Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan
under the "due-on-sale" clause, if any, applicable thereto; PROVIDED, HOWEVER,
that the Master Servicer shall not be required to take such action if in its
sole business judgment the Master Servicer believes it is not in the best
interests of the Trust Fund and shall not exercise any such rights if prohibited
by law from doing so. If the Master Servicer reasonably believes it is unable
under applicable law to enforce such "due-on-sale" clause, or if any of the
other conditions set forth in the proviso to the preceding sentence apply, the
Master Servicer will enter into an assumption and modification agreement from or
with the person to whom such property has been conveyed or is proposed to be
conveyed, pursuant to which such person becomes liable under the Mortgage Note
and, to the extent permitted by applicable state law, the Mortgagor remains
liable thereon. The Master Servicer is also authorized to enter into a
substitution of liability agreement with such person, pursuant to which the
original Mortgagor is released from liability and such person is substituted as
the Mortgagor and becomes liable under the Mortgage Note, provided that no such
substitution shall be effective unless such person satisfies the underwriting
criteria of the Master Servicer and has a credit risk rating at least equal to
that of the original Mortgagor. In connection with any assumption or
substitution, the Master Servicer shall apply such underwriting standards and
follow such practices and procedures as shall be normal and usual in its general
mortgage servicing activities and as it applies to other mortgage loans owned
solely by it. The Master Servicer shall not take or enter into any assumption
and modification agreement, however, unless (to the extent practicable in the


                                       84

<PAGE>



circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy. Any fee collected by
the Master Servicer in respect of an assumption, modification or substitution of
liability agreement shall be retained by the Master Servicer as additional
servicing compensation. In connection with any such assumption, no material term
of the Mortgage Note (including but not limited to the related Mortgage Rate and
the amount of the Monthly Payment) may be amended or modified, except as
otherwise required pursuant to the terms thereof. The Master Servicer shall
notify the Trustee that any such substitution, modification or assumption
agreement has been completed by forwarding to the Trustee the executed original
of such substitution, modification or assumption agreement, which document shall
be added to the related Mortgage File and shall, for all purposes, be considered
a part of such Mortgage File to the same extent as all other documents and
instruments constituting a part thereof.

          The Master Servicer shall be entitled to any Prepayment Interest
Excess which it may withdraw from the Collection Account pursuant to Section
3.11(a).

          Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Master Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Master Servicer may be restricted by law from preventing,
for any reason whatever. For purposes of this Section 3.15, the term
"assumption" is deemed to also include a sale (of the Mortgaged Property)
subject to the Mortgage that is not accompanied by an assumption or substitution
of liability agreement.

          SECTION 3.16. Realization Upon Defaulted Mortgage Loans.

          (a) The Master Servicer shall use its best efforts, in as practical a
time frame as possible and consistent with Servicing Standard, to foreclose upon
or otherwise comparably convert the ownership of properties securing such of the
Mortgage Loans (including, if such is the action to be taken that results from
adherence to the Loss Mitigation Procedures, selling any such Mortgage Loans
other than converting the ownership of the related properties as provided in
Section 3.16(e) below) as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments
pursuant to Section 3.07. The Master Servicer shall be responsible for all costs
and expenses incurred by it in any such proceedings; PROVIDED, HOWEVER, that
such costs and expenses will be recoverable as Servicing Advances by the Master
Servicer as contemplated in Section 3.11 and Section 3.23. The foregoing is
subject to the provision that, in any case in which a Mortgaged Property shall
have suffered damage from an Uninsured Cause, the Master Servicer shall not be
required to expend its own funds toward the restoration of such property unless
it shall determine in its discretion that such restoration will increase the
proceeds of liquidation of the related Mortgage Loan after reimbursement to
itself for such expenses.

          (b) Notwithstanding the foregoing provisions of this Section 3.16 or
any other provision of this Agreement, with respect to any Mortgage Loan as to
which the Master Servicer has received actual notice of, or has actual knowledge
of, the presence of any toxic or hazardous substance on the related Mortgaged
Property, the Master Servicer shall not, on behalf of the Trustee, either (i)
obtain title to such Mortgaged Property as a result of or in lieu of foreclosure
or otherwise, or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged


                                       85

<PAGE>



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

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

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

          Notwithstanding the foregoing, if such environmental audit reveals, or
if the Master Servicer has actual knowledge or notice, that such Mortgaged
Property contains such wastes or substances, the Master Servicer shall not
foreclose or accept a deed in lieu of foreclosure without the prior written
consent of the NIMS Insurer.

          The cost of the environmental audit report contemplated by this
Section 3.16 shall be advanced by the Master Servicer, subject to the Master
Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.11(a)(vii), such right of reimbursement being prior to the
rights of Certificateholders to receive any amount in the Collection Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

          If the Master Servicer determines, as described above, that it is in
the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Master Servicer shall take such action as it deems to be in the best
economic interest of the Trust Fund; PROVIDED that any amounts disbursed by the
Master Servicer pursuant to this Section 3.16(b) shall constitute Servicing
Advances, subject to Section 4.04(d). The cost of any such compliance,
containment, cleanup or remediation shall be advanced by the Master Servicer,
subject to the Master Servicer's right to be reimbursed therefor from the
Collection Account as provided in Section 3.11(a)(iii) and (a)(vii), such right
of reimbursement being prior to the rights of Certificateholders to receive any
amount in the Collection Account received in respect of the affected Mortgage
Loan or other Mortgage Loans.

          (c) (i) The NIMS Insurer may, at its option, purchase a Mortgage Loan
which has become 90 or more days delinquent or for which the Master Servicer has
accepted a deed in lieu


                                       86

<PAGE>



of foreclosure. Prior to purchase pursuant to this Section 3.16(c)(i), the
Master Servicer shall be required to continue to make Advances pursuant to
Section 4.04. The NIMS Insurer shall not use any procedure in selecting Mortgage
Loans to be repurchased which is materially adverse to the interests of the
Certificateholders. The NIMS Insurer shall purchase such delinquent Mortgage
Loan at a price equal to the Purchase Price of such Mortgage Loan. Any such
purchase of a Mortgage Loan pursuant to this Section 3.16(c)(i) shall be
accomplished by remittance to the Master Servicer for deposit in the Collection
Account of the amount of the Purchase Price. The Trustee shall immediately
effectuate the conveyance of such delinquent Mortgage Loan to the NIMS Insurer
to the extent necessary, including the prompt delivery of all documentation to
the NIMS Insurer.

          (ii) If the Master Servicer Optional Purchase Delinquency Trigger has
been met, the Master Servicer may, at its option, purchase a Mortgage Loan which
has become 90 or more days delinquent or for which the Master Servicer has
accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this
Section 3.16(c)(ii), the Master Servicer shall be required to continue to make
Advances pursuant to Section 4.04. The Master Servicer shall purchase such
delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage
Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(ii)
shall be accomplished by deposit in the Collection Account of the amount of the
Purchase Price. The Trustee shall immediately effectuate the conveyance of such
delinquent Mortgage Loan to the Master Servicer to the extent necessary,
including the prompt delivery of all documentation to the Master Servicer.

          Notwithstanding the foregoing: (A) the Master Servicer shall have the
option to purchase pursuant to this Section 3.16(c)(ii) only such delinquent
Mortgage Loans having an aggregate Principal Balance such that, if such
delinquent Mortgage Loans were not in the Trust, the Master Servicer Optional
Purchase Delinquency Trigger would not be met; (B) if the Master Servicer
purchases any delinquent Mortgage Loans pursuant to this Section 3.16(c)(ii), it
must purchase Mortgage Loans that are delinquent the greatest number of days
before it may purchase any that are delinquent any fewer number of days; (C) if
the Master Servicer purchases some but not all Mortgage Loans that are
delinquent any given number of days, it must purchase Mortgage Loans having the
same delinquency status in the order of lowest Principal Balance to highest
Principal Balance; (D) the Master Servicer may at any time relinquish its rights
to purchase delinquent Mortgage Loans pursuant to this Section 3.16(C)(ii) in
writing delivered to the Trustee, and from and after the taking of such action
by the Master Servicer, the provisions of this Section 3.16(c)(ii) shall no
longer be of any force or effect.

          (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds, Liquidation Proceeds or condemnation proceeds, in respect of
any Mortgage Loan, will be applied in the following order of priority: FIRST, to
unpaid Servicing Fees; SECOND, to reimburse the Master Servicer or any Sub-
Servicer for any related unreimbursed Servicing Advances pursuant to Section
3.11(a)(iii) and Advances pursuant to Section 3.11(a)(ii); THIRD, to accrued and
unpaid interest on the Mortgage Loan, to the date of the Final Recovery
Determination, or to the Due Date prior to the Distribution Date on which such
amounts are to be distributed if not in connection with a Final Recovery
Determination; and FOURTH, as a recovery of principal of the Mortgage Loan. The
portion of the recovery so allocated to unpaid Servicing Fees shall be
reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section
3.11(a)(iii).


                                       87

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

          (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full shall be escrowed in
a manner customary for such purposes, the Master Servicer shall deliver to the
Trustee, in written (with two executed copies) or electronic format, a Request
for Release in the form of Exhibit E (which certification shall include a
statement to the effect that all amounts received or to be received in
connection with such payment which are required to be deposited in the
Collection Account pursuant to Section 3.10 have been or will be so deposited)
signed by a Servicing Officer (or in a mutually agreeable electronic format that
will, in lieu of a signature on its face, originate from a Servicing Officer)
and shall request delivery to it of the Mortgage File. Upon receipt of such
certification and request, the Trustee shall, within three Business Days,
release and send by overnight mail, at the expense of the Master Servicer, the
related Mortgage File to the Master Servicer. The Trustee agrees to indemnify
the Master Servicer, out of its own funds, for any loss, liability or expense
(other than special, indirect, punitive or consequential damages which will not
be paid by the Trustee) incurred by the Master Servicer as a proximate result of
the Trustee's breach of its obligations pursuant to this Section 3.17. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account or the Distribution
Account.

          (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Trustee shall, upon any
request made by or on behalf of the Master Servicer and delivery to the Trustee,
in written (with two executed copies) or electronic format, of a Request for
Release in the form of Exhibit E signed by a Servicing Officer (or in a mutually
agreeable electronic format that will, in lieu of a signature on its face,
originate from a Servicing Officer), release the related Mortgage File to the
Master Servicer within three Business Days, and the Trustee shall, at the
direction of the Master Servicer, execute such documents as shall be necessary
to the prosecution of any such proceedings. Such Request for Release shall
obligate the Master Servicer to return each and every document previously
requested from the Mortgage File to the Trustee when the need therefor by the
Master Servicer no longer exists, unless the Mortgage Loan has been liquidated
and the Liquidation Proceeds relating to the Mortgage Loan have been deposited
in the Collection Account or the Mortgage File or such document has been
delivered to an attorney, or to a public trustee or other public official as
required by law, for purposes of initiating or pursuing legal action or other
proceedings for the foreclosure of the Mortgaged Property either judicially or
non- judicially, and the Master Servicer has delivered, or caused to be
delivered, to the Trustee an additional Request for Release certifying as to
such liquidation or action or proceedings. Upon the request of the Trustee, the
Master Servicer shall provide notice to the Trustee of the name and address of
the Person to which such Mortgage File or such document was delivered and the
purpose or purposes of such delivery. Upon receipt of a Request for Release, in
written (with two executed copies) or electronic format, from a Servicing
Officer stating that such Mortgage Loan was liquidated and that all amounts
received or to be received in connection with such liquidation that are required
to be deposited into the Collection Account have been so deposited, or that such
Mortgage Loan has become an REO Property, such Mortgage Loan shall be released
by the Trustee to the Master Servicer or its designee.



                                       88

<PAGE>



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

          SECTION 3.18. Servicing Compensation.

          As compensation for the activities of the Master Servicer hereunder,
the Master Servicer shall be entitled to the Servicing Fee with respect to each
Mortgage Loan payable solely from payments of interest in respect of such
Mortgage Loan, subject to Section 3.24. In addition, the Master Servicer shall
be entitled to recover unpaid Servicing Fees out of Insurance Proceeds,
Liquidation Proceeds or condemnation proceeds to the extent permitted by Section
3.11(a)(iii) and out of amounts derived from the operation and sale of an REO
Property to the extent permitted by Section 3.23. Except as provided in Section
3.29, the right to receive the Servicing Fee may not be transferred in whole or
in part except in connection with the transfer of all of the Master Servicer's
responsibilities and obligations under this Agreement; PROVIDED, HOWEVER, that
the Master Servicer may pay from the Servicing Fee any amounts due to a
Sub-Servicer pursuant to a Sub-Servicing Agreement entered into under Section
3.02.

          Additional servicing compensation in the form of assumption fees, late
payment charges, insufficient funds charges, ancillary income or otherwise
(other than Prepayment Charges) shall be retained by the Master Servicer only to
the extent such fees or charges are received by the Master Servicer. The Master
Servicer shall also be entitled pursuant to Section 3.11(a)(iv) to withdraw from
the Collection Account and pursuant to Section 3.23(b) to withdraw from any REO
Account, as additional servicing compensation, interest or other income earned
on deposits therein, subject to Section 3.12 and Section 3.24. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities hereunder (including premiums for the insurance
required by Section 3.14, to the extent such premiums are not paid by the
related Mortgagors or by a Sub-Servicer and servicing compensation of each
Sub-Servicer) and shall not be entitled to reimbursement therefor except as
specifically provided herein.

          The Master Servicer shall be entitled to any Prepayment Interest
Excess, which it may withdraw from the Collection Account pursuant to Section
3.11(a)(ix).

          SECTION 3.19. Reports to the Trustee; Collection Account Statements.

          Not later than twenty days after each Distribution Date, the Master
Servicer shall forward to the NIMS Insurer and, upon request, to the Trustee and
the Depositor the most current available bank statement for the Collection
Account. Copies of such statement shall be provided by


                                       89

<PAGE>



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

          SECTION 3.20. Statement as to Compliance.

          The Master Servicer will deliver to the Trustee, the NIMS Insurer and
the Depositor not later than February 28th, commencing in 2004, an Officers'
Certificate substantially in the form of Exhibit S attached hereto stating, as
to each signatory thereof, that (i) a review of the activities of the Master
Servicer during the preceding year and of performance under this Agreement has
been made under such officers' supervision and (ii) to the best of such
officers' knowledge, based on such review, the Master Servicer has fulfilled all
of its obligations under this Agreement throughout such year, or, if there has
been a default in the fulfillment of any such obligation, specifying each such
default known to such officer and the nature and status thereof. Copies of any
such statement shall be provided by the Trustee to any Certificateholder and to
any Person identified to the Trustee as a prospective transferee of a
Certificate, upon request at the expense of the requesting party, provided such
statement is delivered by the Master Servicer to the Trustee.

          SECTION 3.21. Independent Public Accountants' Servicing Report.

          Not later than February 28th, commencing in 2004, the Master Servicer,
at its expense, shall cause a nationally recognized firm of independent
certified public accountants to furnish to the Master Servicer a report stating
that (i) it has obtained a letter of representation regarding certain matters
from the management of the Master Servicer which includes an assertion that the
Master Servicer has complied with certain minimum residential mortgage loan
servicing standards, identified in the Uniform Single Attestation Program for
Mortgage Bankers established by the Mortgage Bankers Association of America,
with respect to the servicing of residential mortgage loans during the most
recently completed fiscal year and (ii) on the basis of an examination conducted
by such firm in accordance with standards established by the American Institute
of Certified Public Accountants, such representation is fairly stated in all
material respects, subject to such exceptions and other qualifications that may
be appropriate. In rendering its report such firm may rely, as to matters
relating to the direct servicing of residential mortgage loans by Sub-Servicers,
upon comparable reports of firms of independent certified public accountants
rendered on the basis of examinations conducted in accordance with the same
standards (rendered within one year of such report) with respect to those
Sub-Servicers. Immediately upon receipt of such report, the Master Servicer
shall furnish a copy of such report to the Trustee, the NIMS Insurer and each
Rating Agency. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Master Servicer's expense, provided that
such statement is delivered by the Master Servicer to the Trustee.

          SECTION 3.22. Access to Certain Documentation; Filing of Reports by
                        Trustee.

          (a) The Master Servicer shall provide to the Office of Thrift
Supervision, the FDIC, and any other federal or state banking or insurance
regulatory authority that may exercise authority over any Certificateholder or
Certificate Owner, access to the documentation regarding the


                                       90

<PAGE>



Mortgage Loans required by applicable laws and regulations. Such access shall be
afforded without charge, but only upon reasonable request and during normal
business hours at the offices of the Master Servicer designated by it. In
addition, access to the documentation regarding the Mortgage Loans will be
provided to any Certificateholder or Certificate Owner, the Trustee, the NIMS
Insurer and to any Person identified to the Master Servicer as a prospective
transferee of a Certificate, upon reasonable request during normal business
hours at the offices of the Master Servicer designated by it at the expense of
the Person requesting such access.

          (b) The Trustee 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
on behalf of the Trust any Forms 8-K and 10-K customary for similar securities
as required by the Exchange Act and the Rules and Regulations of the Securities
and Exchange Commission thereunder, and the Depositor shall sign and the Trustee
shall file (via the Securities and Exchange Commission's Electronic Data
Gathering and Retrieval System) such forms on behalf of the Depositor. The
Depositor hereby grants to the Trustee a limited power of attorney to execute
any Form 8-K and file each such document on behalf of the Depositor. Such power
of attorney shall continue until the earlier of (i) receipt by the Trustee from
the Depositor of written termination of such power of attorney and (ii) the
termination of the Trust. Notwithstanding anything herein to the contrary, the
Depositor, and not the Trustee, shall be responsible for executing each Form
10-K filed on behalf of the Trust.

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

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



                                       91

          In addition, the Trustee shall indemnify and hold harmless the
Depositor and its officers, directors and Affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach of the Trustee's obligations under this Section 3.22(b) or
the Trustee's negligence, bad faith or willful misconduct in connection
therewith. If the indemnification provided for herein is unavailable or
insufficient to hold harmless the Depositor, then the Trustee, 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,
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.

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

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

          (g) To the extent that, following the Closing Date, the Depositor
certifies that reports and certifications differing from those required under
this Section 3.22(b) comply with the reporting requirements under the Exchange
Act, the Trustee hereby agrees that it will reasonably cooperate to amend the
provisions of this Section 3.22(b) in order to comply with such amended
reporting requirements and such amendment of this Section 3.22(b). Any such
amendment may result in the reduction of the reports filed by the Depositor
under the Exchange Act. Notwithstanding the foregoing, the Trustee shall not be
obligated to enter into any amendment pursuant to this Section that adversely
affects its obligations and immunities under this Agreement.

          SECTION 3.23. Title, Management and Disposition of REO Property.

          (a) The deed or certificate of sale of any REO Property shall be taken
in the name of the Trustee, or its nominee, in trust for the benefit of the
Certificateholders. The Master Servicer, on behalf of REMIC 1, shall sell any
REO Property as soon as practical and in any event no later than the end of the
third full taxable year after the taxable year in which such REMIC acquires
ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or
request from the Internal Revenue Service, no later than 60 days before the day
on which the three-year grace period would otherwise expire, an extension of
such three-year period, unless the Master Servicer shall have delivered to the
Trustee and the NIMS Insurer an Opinion of Counsel acceptable to the NIMS
Insurer and addressed to the Trustee, the NIMS Insurer and the Depositor, to the
effect that the holding by the REMIC of such REO Property subsequent to three
years after its acquisition will not result in the imposition on the REMIC of
taxes on "prohibited transactions" thereof, as defined in Section 860F of the
Code, or cause any of the REMICs created hereunder to fail to qualify as a REMIC
under Federal law at any time that any Certificates are outstanding. The Master
Servicer shall manage, conserve, protect and operate each REO Property for the
Certificateholders solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code or
result in the receipt by any of the REMICs created hereunder of any "income from
non-permitted


                                       92

<PAGE>



assets" within the meaning of Section 860F(a)(2)(B) of the Code, or any "net
income from foreclosure property" which is subject to taxation under the REMIC
Provisions.

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

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

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

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

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

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

          Notwithstanding the foregoing, neither the Master Servicer nor the
Trustee shall:

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



                                       93

<PAGE>



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

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

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

unless, in any such case, the Master Servicer has obtained an Opinion of
Counsel, provided to the Trustee and the NIMS Insurer, to the effect that such
action will not cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code at any time that
it is held by the REMIC, in which case the Master Servicer may take such actions
as are specified in such Opinion of Counsel.

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

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

          (2) any such contract shall require, or shall be administered to
     require, that the Independent Contractor pay all costs and expenses
     incurred in connection with the operation and management of such REO
     Property, including those listed above and remit all related revenues (net
     of such costs and expenses) to the Master Servicer as soon as practicable,
     but in no event later than thirty days following the receipt thereof by
     such Independent Contractor;

          (3) none of the provisions of this Section 3.23(c) relating to any
     such contract or to actions taken through any such Independent Contractor
     shall be deemed to relieve the Master Servicer of any of its duties and
     obligations to the Trustee on behalf of the Certificateholders with respect
     to the operation and management of any such REO Property; and

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

          The Master Servicer shall be entitled to enter into any agreement with
any Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Master Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. The Master Servicer shall be solely liable for
all fees owed by it to any such Independent Contractor, irrespective of whether
the


                                       94

<PAGE>



Master Servicer's compensation pursuant to Section 3.18 is sufficient to pay
such fees; PROVIDED, HOWEVER, that to the extent that any payments made by such
Independent Contractor would constitute Servicing Advances if made by the Master
Servicer, such amounts shall be reimbursable as Servicing Advances made by the
Master Servicer.

          (d) In addition to the withdrawals permitted under Section 3.23(c),
the Master Servicer may from time to time make withdrawals from the REO Account
for any REO Property: (i) to pay itself or any Sub-Servicer unpaid Servicing
Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or
any Sub-Servicer for unreimbursed Servicing Advances and Advances made in
respect of such REO Property or the related Mortgage Loan. On the Master
Servicer Remittance Date, the Master Servicer shall withdraw from each REO
Account maintained by it and deposit into the Distribution Account in accordance
with Section 3.10(d)(ii), for distribution on the related Distribution Date in
accordance with Section 4.01, the income from the related REO Property received
during the prior calendar month, net of any withdrawals made pursuant to Section
3.23(c) or this Section 3.23(d).

          (e) Subject to the time constraints set forth in Section 3.23(a), each
REO Disposition shall be carried out by the Master Servicer in a manner, at such
price and upon such terms and conditions as shall be in conformity with the
requirements of the Loss Mitigation Procedures and as shall be normal and usual
in its Servicing Standard.

          (f) The proceeds from the REO Disposition, net of any amount required
by law to be remitted to the Mortgagor under the related Mortgage Loan and net
of any payment or reimbursement to the Master Servicer or any Sub-Servicer as
provided above, shall be deposited in the Distribution Account in accordance
with Section 3.10(d)(ii) on the Master Servicer Remittance Date in the month
following the receipt thereof for distribution on the related Distribution Date
in accordance with Section 4.01. Any REO Disposition shall be for cash only
(unless changes in the REMIC Provisions made subsequent to the Startup Day allow
a sale for other consideration).

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

          SECTION 3.24. Obligations of the Master Servicer in Respect of
                        Prepayment Interest Shortfalls.

          Not later than 1:00 p.m. New York time on each Master Servicer
Remittance Date, the Master Servicer shall remit to the Distribution Account an
amount ("Compensating Interest") equal to the lesser of (A) the aggregate of the
Prepayment Interest Shortfalls for the related Distribution Date and (B) its
aggregate Servicing Fee for the related Due Period, any interest or investment
income earned on funds deposited in the Collection Account and any Prepayment
Interest Excess earned during the related Prepayment Period. The Master Servicer
shall not have the right to reimbursement for any amounts remitted to the
Trustee in respect of Compensating Interest. Such


                                       95

<PAGE>



amounts so remitted shall be included in the Available Funds and distributed
therewith on the next Distribution Date. The Master Servicer shall not be
obligated to pay Compensating Interest with respect to Relief Act Interest
Shortfalls.

          SECTION 3.25. Convertible Mortgage Loans.

          With respect to any Convertible Mortgage Loan where the Mortgagor has
chosen to exercise its option to convert the Mortgage Rate thereunder, the
Master Servicer shall determine the fixed rate for such Convertible Mortgage
Loan in accordance with the terms of the applicable Mortgage Note and to
otherwise determine whether the related Mortgagor has complied with the
requirements thereof in order to exercise the conversion option.

          SECTION 3.26. Obligations of the Master Servicer in Respect of
                        Mortgage Rates and Monthly Payments.

          In the event that a shortfall in any collection on or liability with
respect to the Mortgage Loans in the aggregate results from or is attributable
to adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances
that were made by the Master Servicer in a manner not consistent with the terms
of the related Mortgage Note and this Agreement, the Master Servicer, upon
discovery or receipt of notice thereof, immediately shall deposit in the
Collection 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. Notwithstanding the
foregoing, this Section 3.26 shall not limit the ability of the Master Servicer
to seek recovery of any such amounts from the related Mortgagor under the terms
of the related Mortgage Note, as permitted by law.

          SECTION 3.27. Solicitations.

          From and after the Closing Date, the Master Servicer agrees that it
will not take any action or permit or cause any action to be taken by any of its
agents and Affiliates, or by any independent contractors or independent mortgage
brokerage companies on the Master Servicer's behalf, to personally, by
telephone, mail or electronic mail, solicit the Mortgagor under any Mortgage
Loan for the purpose of refinancing such Mortgage Loan; PROVIDED, that the
Master Servicer may solicit any Mortgagor for whom the Master Servicer has
received a request for verification of mortgage, a request for demand for
payoff, a mortgagor initiated written or verbal communication indicating a
desire to prepay the related Mortgage Loan, another mortgage company has pulled
a credit report on the mortgagor or the mortgagor initiates a title search;
provided further, it is understood and agreed that promotions undertaken by the
Master Servicer or any of its Affiliates which (i) concern optional insurance
products or other additional products or (ii) are directed to the general public
at large, including, without limitation, mass mailings based on commercially
acquired mailing lists, newspaper, radio and television advertisements shall not
constitute solicitation under this Section, nor is the Master Servicer
prohibited from responding to unsolicited requests or inquiries made by a
Mortgagor or an agent of a Mortgagor. Furthermore, the Master Servicer shall be
permitted to include in its monthly statements to borrowers or otherwise,
statements regarding


                                       96

<PAGE>



the availability of the Master Servicer's counseling services with respect to
refinancing mortgage loans.

          SECTION 3.28. Net WAC Rate Carryover Reserve Account.

          No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, segregated trust account titled, "Net WAC Rate
Carryover Reserve Account, Wells Fargo Bank Minnesota, National Association, as
Trustee, in trust for registered Holders of Option One Mortgage Loan Trust
2003-4, Asset-Backed Certificates, Series 2003-4." On the Closing Date, the
Depositor will deposit, or cause to be deposited, into the Net WAC Rate
Carryover Reserve Account $1,000. In addition, the amount deposited in the Net
WAC Rate Carryover Reserve Account will be increased by any payments received by
the Trustee under the Cap Contract and deposited into the Net WAC Rate Carryover
Reserve Account.

          On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A Certificates and/or the Mezzanine
Certificates, the Trustee has been directed by the Class C Certificateholders
to, and therefore will, deposit into the Net WAC Rate Carryover Reserve Account
the amounts described in Section 4.01(d)(xiii), rather than distributing such
amounts to the Class C Certificateholders. On each such Distribution Date, the
Trustee shall hold all such amounts for the benefit of the Holders of the Class
A Certificates and the Mezzanine Certificates, and will distribute such amounts
to the Holders of the Class A Certificates and/or the Mezzanine Certificates in
the amounts and priorities set forth in Section 4.01(d). If no Net WAC Rate
Carryover Amounts are payable on a Distribution Date, the Trustee shall deposit
into the Net WAC Rate Carryover Reserve Account on behalf of the Class C
Certificateholders, from amounts otherwise distributable to the Class C
Certificateholders, an amount such that when added to other amounts already on
deposit in the Net WAC Rate Carryover Reserve Account, the aggregate amount on
deposit therein is equal to $1,000.

          For federal and state income tax purposes, the Class C
Certificateholders will be deemed to be the owners of the Net WAC Rate Carryover
Reserve Account and all amounts deposited into the Net WAC Rate Carryover
Reserve Account shall be treated as amounts distributed by REMIC 3 to the Holder
of the Class C Certificates. Upon the termination of the Trust, or the payment
in full of the Class A Certificates and the Mezzanine Certificates, all amounts
remaining on deposit in the Net WAC Rate Carryover Reserve Account will be
released by the Trust and distributed to the Class C Certificateholders or their
designees. The Net WAC Rate Carryover Reserve Account will be part of the Trust
but not part of any REMIC and any payments to the Holders of the Class A
Certificates or the Mezzanine Certificates of Net WAC Rate Carryover Amounts
will not be payments with respect to a "regular interest" in a REMIC within the
meaning of Code Section 860(G)(a)(1).

          By accepting a Class C Certificate, each Class C Certificateholder
hereby agrees to direct the Trustee, and the Trustee hereby is directed, to
deposit into the Net WAC Rate Carryover Reserve Account the amounts described
above on each Distribution Date as to which there is any Net WAC Rate Carryover
Amount rather than distributing such amounts to the Class C Certificateholders.
By accepting a Class C Certificate, each Class C Certificateholder further
agrees


                                       97

<PAGE>



that such direction is given for good and valuable consideration, the receipt
and sufficiency of which is acknowledged by such acceptance.

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

          For federal tax return and information reporting, the right of the
Class A Certificateholders and the Mezzanine Certificateholders to receive
payments from the Net WAC Rate Carryover Reserve Account in respect of any Net
Wac Rate Carryover Amount shall be assigned a value of zero.

          SECTION 3.29. Advance Facility.

          (a) The Master Servicer and/or the Trustee on behalf of the Trust
Fund, in either case, with the consent of the NIMS Insurer and the Master
Servicer in the case of the Trustee, is hereby authorized to enter into a
facility (the "Advance Facility") with any Person which provides that such
Person (an "Advancing Person") may fund Advances and/or Servicing Advances to
the Trust Fund under this Agreement, although no such facility shall reduce or
otherwise affect the Master Servicer's obligation to fund such Advances and/or
Servicing Advances. If the Master Servicer enters into such an Advance Facility
pursuant to this Section 3.29, upon reasonable request of the Advancing Person,
the Trustee shall execute a letter of acknowledgment, confirming its receipt of
notice of the existence of such Advance Facility. To the extent that an
Advancing Person funds any Advance or any Servicing Advance and provides the
Trustee with notice acknowledged by the Servicer that such Advancing Person is
entitled to reimbursement, such Advancing Person shall be entitled to receive
reimbursement pursuant to this Agreement for such amount to the extent provided
in Section 3.29(b). Such notice from the Advancing Person must specify the
amount of the reimbursement, the Section of this Agreement that permits the
applicable Advance or Servicing Advance to be reimbursed and the section(s) of
the Advance Facility that entitle the Advancing Person to request reimbursement
from the Trustee, rather than the Master Servicer, and include the Master
Servicer's acknowledgment thereto or proof of an Event of Default under the
Advance Facility. The Trustee shall have no duty or liability with respect to
any calculation of any reimbursement to be paid to an Advancing Person and shall
be entitled to rely without independent investigation on the Advancing Person's
notice provided pursuant to this Section 3.29. An Advancing Person whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the qualifications of a Master Servicer
or a Sub-




                                       98
<PAGE>


Servicer pursuant to Section 6.06 hereof and will not be deemed to be a
Sub-Servicer under this Agreement. If the terms of a facility proposed to be
entered into with an Advancing Person by the Trust Fund would not materially and
adversely affect the interests of any Certificateholder, then the NIMS Insurer
shall not withhold its consent to the Trust Fund's entering such facility.

          (b) If an Advancing Facility is entered into, then the Master Servicer
shall not be permitted to reimburse itself therefor under Section 3.11(a)(ii),
Section 3.11(a)(iii), Section 3.11(a)(vi), Section 3.11(a)(vii) Section
3.11(a)(viii) and Section 4.04(b) prior to the remittance to the Trust Fund, but
instead the Master Servicer shall include such amounts in the applicable
remittance to the Trustee made pursuant to Section 3.10(a). The Trustee is
hereby authorized to pay to the Advancing Person, reimbursements for Advances
and Servicing Advances from the Distribution Account to the same extent the
Master Servicer would have been permitted to reimburse itself for such Advances
and/or Servicing Advances in accordance with Section 3.11(a)(ii), Section
3.11(a)(iii), Section 3.11(a)(vi), Section 3.11(a)(vii), Section 3.11(a)(viii)
or Section 4.04(b), as the case may be, had the Master Servicer itself funded
such Advance or Servicing Advance. The Trustee is hereby authorized to pay
directly to the Advancing Person such portion of the Servicing Fee as the
parties to any advancing facility agree.

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

          (d) Any amendment to this Section 3.29 or to any other provision of
this Agreement that may be necessary or appropriate to effect the terms of an
Advance Facility as described generally in this Section 3.29, including
amendments to add provisions relating to a successor master servicer, may be
entered into by the Trustee and the Master Servicer without the consent of any
Certificateholder but with the consent of the NIMS Insurer, notwithstanding
anything to the contrary in this Agreement.

          SECTION 3.30. PMI Policy; Claims Under the PMI Policy.

          Notwithstanding anything to the contrary elsewhere in this Article
III, the Master Servicer shall not agree to any modification or assumption of a
PMI Mortgage Loan or take any other action with respect to a PMI Mortgage Loan
that could result in denial of coverage under the PMI Policy. The Master
Servicer shall notify the PMI Insurer that the Trustee, on behalf of the
Certificateholders, is the Insured, as that term is defined in the PMI Policy,
of each PMI Mortgage Loan. The Master Servicer shall, on behalf of the Trustee,
prepare and file on a timely basis with the PMI Insurer, with a copy to the
Trustee, all claims which may be made under the PMI Policy with respect to the
PMI Mortgage Loans. Consistent with all rights and obligations hereunder, the
Master Servicer shall take all actions required under the PMI Policy as a
condition to the payment of any such claim. Any amount received from the PMI
Insurer with respect to any such PMI Mortgage Loan shall be deposited by the
Master Servicer, no later than two Business Days following receipt thereof, into
the Collection Account.

          In the case of information furnished pursuant to subclauses (i)

year, the Trustee shall, upon written request, furnish to the NIMS Insurer and
each Person who at any time during the calendar year was a Certificateholder of
a Regular Certificate, if requested in writing by such Person, such information
as is reasonably necessary to provide to such Person a statement containing the
information set forth in subclauses (i) through (iii) above, aggregated for such
calendar year or applicable portion thereof during which such Person was a

requirements of the Code as are in force from time to time.

          (c) On each Distribution Date, the Trustee shall forward to the NIMS
Insurer and the Class R Certificateholders a copy of the reports forwarded to

          (d) Within a reasonable period of time after the end of each calendar
year, the Trustee shall deliver to the NIMS Insurer and each Person who at any
time during the calendar year was a Class R Certificateholder, if requested in
writing by such Person, such information as is reasonably necessary to provide

          SECTION 4.04. Remittance Reports; Advances.

          (a) On the second Business Day following each Determination Date but
in no event later than the earlier of (i) such date which would allow the
indenture trustee to submit a claim to the NIMS Insurer under the Indenture so
as to allow a timely payment by the NIMS Insurer under the insurance policy
related to the notes insured by the NIMS Insurer and (ii) the 20th day of each
month (or if such 20th day is not a Business Day, the preceding Business Day),
the Master Servicer shall deliver to the Trustee and the NIMS Insurer by
telecopy or electronic mail (or by such other means as the Master Servicer and
the Trustee may agree from time to time) a Remittance Report with respect to the
related Distribution Date. Not later than the 20th day of each month (or if such
20th day is not a Business Day, the preceding Business Day), the Master 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
require to perform the calculations necessary to make the distributions
contemplated by Section 4.01 and to prepare the statements to Certificateholders
contemplated by Section 4.03. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Master Servicer.



                                      110
<PAGE>



          (b) The amount of Advances to be made by the Master Servicer for any
Distribution Date shall equal, subject to Section 4.04(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Due Period in respect of the 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 Due Period and as to
which REO Property an REO Disposition did not occur during the related Due
Period, an amount equal to the excess, if any, of the REO Imputed Interest on
such REO Property for the most recently ended calendar month, over the net
income from such REO Property transferred to the Distribution Account pursuant
to Section 3.23 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.

          On or before 1:00 p.m. New York time on the Master Servicer Remittance
Date, the Master Servicer shall remit in immediately available funds to the
Trustee for deposit in the Distribution Account an amount equal to the aggregate
amount of Advances, if any, to be made in respect of the Mortgage Loans and REO
Properties for the related Distribution Date either (i) from its own funds or
(ii) from the Collection Account, to the extent of funds held therein for future
distribution (in which case it will cause to be made an appropriate entry in the
records of Collection Account that amounts held for future distribution have
been, as permitted by this Section 4.04, used by the Master Servicer in
discharge of any such Advance) or (iii) in the form of any combination of (i)
and (ii) aggregating the total amount of Advances to be made by the Master
Servicer with respect to the Mortgage Loans and REO Properties. Any amounts held
for future distribution used by the Master Servicer to make an Advance as
permitted in the preceding sentence or withdrawn by the Master Servicer as
permitted in Section 3.11(a)(ii) in reimbursement of Advances previously made
shall be appropriately reflected in the Master Servicer's records and replaced
by the Master Servicer by deposit in the Collection Account on or before any
future Master Servicer Remittance Date to the extent that the Available Funds
for the related Distribution Date (determined without regard to Advances to be
made on the Master Servicer Remittance Date) shall be less than the total amount
that would be distributed to the Classes of Certificateholders pursuant to
Section 4.01 on such Distribution Date if such amounts held for future
distributions had not been so used to make Advances or reimburse for previously
made Advances. The Trustee will provide notice to the NIMS Insurer and the
Master Servicer by telecopy by the Close of Business on any Master Servicer
Remittance Date in the event that the amount remitted by the Master Servicer to
the Trustee on such date is less than the Advances required to be made by the
Master Servicer for the related Distribution Date, as set forth in the related
Remittance Report.

          (c) The obligation of the Master Servicer to make such Advances is
mandatory, notwithstanding any other provision of this Agreement but subject to
(d) below, and, with respect to any Mortgage Loan, shall continue until the
Mortgage Loan is paid in full 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 Master Servicer
if such Advance or Servicing Advance would, if made, constitute a Nonrecoverable
Advance. The determination by the Master



                                      111
<PAGE>



Servicer that it has made a Nonrecoverable Advance or that any proposed Advance
or Servicing Advance, if made, would constitute a Nonrecoverable Advance, shall
be evidenced by an Officers' Certificate of the Master Servicer delivered to the
NIMS Insurer, the Depositor and the Trustee.

          SECTION 4.05. Pre-Funding Accounts.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain two segregated trust accounts that are each Eligible Accounts, which
shall be titled "Group I Pre-Funding Account, Wells Fargo Bank Minnesota,
National Association, as trustee for the registered holders of Option One
Mortgage Loan Trust 2003-4, Asset-Backed Certificates, Series 2003-4" (the
"Group I Pre-Funding Account") and "Group II Pre-Funding Account, Wells Fargo
Bank Minnesota, National Association, as trustee for the registered holders of
Option One Mortgage Loan Trust 2003- 4, Asset-Backed Certificates, Series

Original Group I Pre-Funded Amount and the Original Group II Pre-Funded Amount,
as applicable, remitted on the Closing Date to the Trustee by the Depositor.
Funds deposited in the Pre-Funding Accounts shall be held in trust by the
Trustee for the Certificateholders for the uses and purposes set forth herein.

          (b) The Trustee will invest funds deposited in the Pre-Funding
Accounts as directed by the Master Servicer in Permitted Investments with a
maturity date (i) no later than the Business Day immediately preceding the date
on which such funds are required to be withdrawn from such account pursuant to
this Agreement, if a Person other than the Trustee or an Affiliate manages or
advises such investment, (ii) no later than the date on which such funds are
required to be withdrawn from such account pursuant to this Agreement, if the
Trustee or an Affiliate manages or advises such investment or (iii) within one
Business Day of the Trustee's receipt thereof. For federal income tax purposes,
the Master Servicer shall be the owner of the Pre-Funding Accounts and shall
report all items of income, deduction, gain or loss arising therefrom. All
income and gain realized from investment of funds deposited in the Group I
Pre-Funding Account and the Group II Pre-Funding Account shall be transferred to
the Depositor or its designee, as applicable, at the following times: (i) on the
Business Day immediately preceding each Distribution Date, if a Person other
than the Trustee or an Affiliate of the Trustee manages or advises such
investment, or on each Distribution Date, if the Trustee or an Affiliate of the
Trustee manages or advises such investment, (ii) on the Business Day immediately
preceding each Subsequent Transfer Date, if a Person other than the Trustee or
an Affiliate of the Trustee manages or advises such investment, or on each
Subsequent Transfer Date, if the Trustee or an Affiliate of the Trustee manages
or advises such investment or (iii) within one Business Day of the Trustee's
receipt thereof. The Master Servicer shall deposit in the Pre-Funding Accounts
the amount of any net loss incurred in respect of any such Permitted Investment
immediately upon realization of such loss without any right of reimbursement
therefor. At no time will the Pre-Funding Accounts be assets of any REMIC
created hereunder].

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

          (i) On any Subsequent Transfer Date, the Trustee shall withdraw from
     the Group I Pre-Funding Account or the Group II Pre-Funding Account, as
     applicable, an amount equal



                                      112

     to 100% of the Stated Principal Balances of the Subsequent Group I Mortgage
     Loans or the Subsequent Group II Mortgage Loans, as applicable, transferred
     and assigned to the Trustee for deposit in the Mortgage Pool on such
     Subsequent Transfer Date and pay such amount to or upon the order of the
     Depositor upon satisfaction of the conditions set forth in Section 2.08
     with respect to such transfer and assignment;

          (ii) If the amount on deposit in the Pre-Funding Accounts (exclusive
     of investment income) has not been reduced to zero during the Funding
     Period, on the day immediately following the termination of the Funding
     Period, the Trustee shall deposit into the Distribution Account any amounts
     remaining in the Pre-Funding Accounts (exclusive of investment income) for
     distribution in accordance with the terms hereof;

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

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

          Withdrawals pursuant to clauses (i), (ii) and (iii) shall be treated
as contributions of cash to REMIC 1 on the date of withdrawal.

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 Trustee 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 Offered Certificates
shall be Book- Entry Certificates. The other Classes of Certificates shall not
be Book-Entry Certificates.

          SECTION 5.02. Registration of Transfer and Exchange of Certificates.

          (a) The Certificate Registrar shall cause to be kept at the Corporate
Trust Office 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.

          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 Class R Certificate,
upon satisfaction of the conditions set forth below, the Trustee on behalf of
the Trust shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates of the same aggregate
Percentage Interest.



                                      118
<PAGE>



          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 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. In addition,
with respect to each Class R Certificate, the holder thereof may exchange, in
the manner described above, such Class R Certificate for three separate
certificates, each representing such holder's respective Percentage Interest in
the Class R-1 Interest, the Class R-2 Interest and the Class R-3 Interest,
respectively, in each case that was evidenced by the Class R Certificate being
exchanged.

          (b) 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. In the event of any conflict between
the terms of any such Letter of Representation and this Agreement, the terms of
this Agreement shall control.

          (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



                                      119
<PAGE>



(y) the Trustee or the Depositor is unable to locate a qualified successor, (ii)
the Depositor, at its sole option, with the consent of the Trustee, elects to
terminate the book-entry system through the Depository or (iii) after the
occurrence of a Master Servicer Event of Termination, the Certificate Owners of
the Book-Entry Certificates representing Percentage Interests of such Classes
aggregating not less than 51% advise 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 Master Servicer's expense, in the case of (i) and (iii) above,
execute on behalf of the Trust and 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 Master Servicer, any Paying Agent and
the Depositor shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder.

          (d) No transfer, sale, pledge or other disposition of any Class C
Certificate, Class P Certificate or Class R 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, except with respect to the initial transfer of any Class C
Certificate, Class P Certificate or Class R Certificates by the Depositor (i)
unless such transfer is made in reliance upon Rule 144A (as evidenced by the
investment letter delivered to the Trustee, in substantially the form attached
hereto as Exhibit J) under the 1933 Act, the Trustee 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 Trustee 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 Trustee or the Depositor or (ii) the Trustee 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) acceptable to and in form
and substance reasonably satisfactory to the Depositor and the Trustee
certifying to the Depositor and the Trustee the facts surrounding such transfer,
which investment letter shall not be an expense of the Trustee or the Depositor.
The Holder of a Class C Certificate, Class P Certificate or Class R Certificate
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee and the Depositor 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 a Class C Certificate, Class P Certificate or Residual
Certificate or any interest therein shall be made to any Plan subject to ERISA
or Section 4975 of the Code, any Person acting, directly or indirectly, on
behalf of any such Plan or any Person acquiring such Certificates with "Plan
Assets" of a Plan within the meaning of the Department of Labor regulation
promulgated at 29 C.F.R. ss. 2510.3-101 ("Plan Assets"), as certified by such
transferee in the form of Exhibit M, unless the Depositor, the Trustee and the
Master Servicer are provided with an Opinion of Counsel which establishes to the
satisfaction of the Depositor, the Trustee and the Master Servicer that the



                                      120
<PAGE>



purchase of such Certificates is permissible under applicable law, will not
constitute or result in any prohibited transaction under ERISA or Section 4975
of the Code and will not subject the Depositor, the Master Servicer, the Trustee
or the Trust Fund to any obligation or liability (including obligations or
liabilities under ERISA or Section 4975 of the Code) in addition to those
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Depositor, the Master Servicer, the Trustee or the Trust Fund. Neither a
certification nor an Opinion of Counsel will be required in connection with the
initial transfer of any such Certificate by the Depositor to an affiliate of the
Depositor (in which case, the Depositor or any affiliate thereof shall have
deemed to have represented that such affiliate is not a Plan or a Person
investing Plan Assets) and the Trustee shall be entitled to conclusively rely
upon a representation (which, upon the request of the Trustee, shall be a
written representation) from the Depositor of the status of such transferee as
an affiliate of the Depositor.

          Each Transferee of a Mezzanine Certificate will be deemed to have
represented by virtue of its purchase or holding of such Certificate (or
interest therein) that either (a) such Transferee is not a Plan or purchasing
such Certificate with Plan Assets, (b) it has acquired and is holding such
Certificate in reliance on Prohibited Transaction Exemption ("PTE") 90-59, 55
Fed. Reg. 36724 (September 6, 1990), as amended by PTE 2002-41, 67 Fed. Reg.
54487 (August 22, 2002) (the "Exemption"), and that it understands that there
are certain conditions to the availability of the Exemption including that such
Certificate must be rated, at the time of purchase, not lower than "BBB-" (or
its equivalent) by a Rating Agency or (c) the following conditions are
satisfied: (i) such Transferee is an insurance company, (ii) the source of funds
used to purchase or hold such Certificate (or interest therein) is an "insurance
company general account" (as defined in U.S. Department of Labor Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (iii) the conditions set forth
in Sections I and III of PTCE 95-60 have been satisfied.

          If any Class C Certificate, Class P Certificate, Mezzanine Certificate
or Residual Certificate or any interest therein is acquired or held in violation
of the provisions of the two preceding paragraphs, the next preceding permitted
beneficial owner will be treated as the beneficial owner of that Certificate
retroactive to the date of transfer to the purported beneficial owner. Any
purported beneficial owner whose acquisition or holding of any such Certificate
or interest therein was effected in violation of the provisions of the preceding
paragraph shall indemnify and hold harmless the Depositor, the Master Servicer,
the NIMS Insurer, the Trustee and the Trust from and against any and all
liabilities, claims, costs or expenses incurred by those parties as a result of
that acquisition or holding.

          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:




                                      121
<PAGE>



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

          (ii) No 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 Trustee 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 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 Trustee 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 Trustee 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 Trustee 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



                                      122
<PAGE>



     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 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 Class R Certificate in violation of the
     restrictions in this Section, then the Trustee upon receipt of reasonable
     compensation 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 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 Trustee and the NIMS Insurer, in form and substance
satisfactory to the Trustee and the NIMS Insurer, (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 created 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 canceled by the Certificate Registrar and disposed of pursuant to its
standard procedures.

          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 Certificate and (ii) there is delivered to
the Trustee, the Depositor, the NIMS Insurer and the Certificate Registrar such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of 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, 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



                                      123
<PAGE>



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 Master Servicer, the Depositor, the Trustee, the NIMS Insurer, the
Certificate Registrar, any Paying Agent and any agent of the Master Servicer,
the Depositor, the Trustee, the NIMS Insurer, 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 for all
other purposes whatsoever, and none of the Master 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.

          (a) The Paying Agent shall make distributions to Certificateholders
from the Distribution Account pursuant to Section 4.01 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 3.11(a) 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 NIMS Insurer.

          (b) The Trustee shall cause the Paying Agent (if other than the
Trustee) to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent shall hold all
sums, if any, held by it for payment to the Certificateholders in trust for the
benefit of the Certificateholders entitled thereto until such sums shall be paid
to such Certificateholders and shall agree that it shall comply with all
requirements of the Code regarding the withholding of payments in respect of
Federal income taxes due from Certificate Owners and otherwise comply with the
provisions of this Agreement applicable to it.

                                   ARTICLE VI

                      THE MASTER SERVICER AND THE DEPOSITOR

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

          The Master Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by Master
Servicer 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 Master Servicer or the Depositor.

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

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

          Neither the Master Servicer or the Depositor nor any of the directors
or officers or employees or agents of the Master 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 Master Servicer or
the Depositor in good faith pursuant to this Agreement, or for errors in
judgment; PROVIDED, HOWEVER, that this provision shall not protect the Master
Servicer, the Depositor or any such Person against any liability which would
otherwise be imposed by reason of its willful misfeasance, bad faith or
negligence in the performance of duties of the Master Servicer or the Depositor,
as the case may be, or by reason of its reckless disregard of its obligations
and duties of the Master Servicer or the Depositor, as the case may be,
hereunder; PROVIDED, FURTHER, that this provision shall not be construed to
entitle the Master Servicer to indemnity in the event that amounts advanced by
the Master Servicer to retire any senior lien exceed Liquidation Proceeds (in
excess of related liquidation expenses) realized with respect to the related
Mortgage Loan. The preceding sentence shall not limit the obligations of the
Master Servicer pursuant to Section 8.05. The Master Servicer and any director
or officer or employee or agent of the Master Servicer 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 Master Servicer and the
Depositor, and any director or officer or employee or agent of the Master
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 related to any specific Mortgage Loan or Mortgage Loans
(except as any such loss, liability or expense shall be otherwise reimbursable
pursuant to this Agreement) and any loss, liability or expense incurred



                                      125
<PAGE>



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 Master 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
Certificateholders hereunder. In such event, unless the Depositor or the Master
Servicer acts without the consent of Holders of Certificates entitled to at
least 51% of the Voting Rights, 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 Master Servicer shall be entitled to be
reimbursed therefor from the Collection Account as and to the extent provided in
Section 3.11, any such right of reimbursement being prior to the rights of the
Certificateholders to receive any amount in the Collection Account. The Master
Servicer's right to indemnity or reimbursement pursuant to this Section shall
survive any resignation or termination of the Master 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 Master Servicer solely in its capacity as Master Servicer hereunder and
in no other capacities.

          The Master Servicer (except the Trustee if it is required to succeed
the Master Servicer hereunder) indemnifies and holds the Trustee, the Depositor,
the NIMS Insurer 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, the NIMS Insurer and any Certificateholder may sustain in any way
related to the failure of the Master Servicer to perform its duties and service
the Mortgage Loans in compliance with the terms of this Agreement. The Master
Servicer shall immediately notify the Trustee, the Depositor, the NIMS Insurer
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 Master 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 Master Servicer, the Trustee, the Depositor, the NIMS Insurer and/or
Certificateholder in respect of such claim. The provisions of this paragraph
shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

          SECTION 6.04. Master Servicer Not to Resign.

          Subject to the provisions of Section 7.01 and Section 6.02, the Master
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 Master Servicer
so causing such a conflict being of a type and nature carried on by the Master
Servicer or its subsidiaries or Affiliates at the date of this Agreement or (ii)
upon satisfaction of the following conditions: (a) the Master Servicer has
proposed a successor servicer to the Trustee and the NIMS Insurer in writing and
such proposed successor servicer is reasonably acceptable to the Trustee and the
NIMS Insurer and (b) each Rating Agency shall have delivered a letter to the
Trustee and the NIMS Insurer prior to the appointment of the successor servicer
stating that the proposed appointment of such successor servicer as Master



                                      126
<PAGE>



Servicer hereunder will not result in the reduction or withdrawal of the then
current rating of the Certificates; PROVIDED, HOWEVER, that no such resignation
by the Master Servicer shall become effective until such successor servicer or,
in the case of (i) above, the Trustee shall have assumed the Master Servicer's
responsibilities and obligations hereunder or the Trustee shall have designated,
with the consent of the NIMS Insurer, a successor servicer in accordance with
Section 7.02. Any such resignation shall not relieve the Master 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 Master Servicer.
Any such determination permitting the resignation of the Master Servicer
pursuant to clause (i) above shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the NIMS Insurer. Any such determination
permitting the resignation of the Master Servicer shall be evidenced by an
Opinion of Counsel to such effect delivered to the Trustee and the NIMS Insurer.

          SECTION 6.05. Delegation of Duties.

          In the ordinary course of business, the Master 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 Master Servicer of its liabilities and responsibilities with respect to such
duties and shall not constitute a resignation within the meaning of Section
6.04. Except as provided in Section 3.02, no such delegation is permitted that
results in the delegee subservicing any Mortgage Loans. The Master Servicer
shall provide the Trustee and the NIMS Insurer with 60 days prior written notice
prior to the delegation of any of its duties to any Person other than any of the
Master Servicer's Affiliates or their respective successors and assigns.

          SECTION 6.06. [Reserved].

          SECTION 6.07. Inspection.

          The Master Servicer, in its capacity as Originator and Master
Servicer, shall afford the Trustee and the NIMS Insurer, upon reasonable advance
notice, during normal business hours, access to all records maintained by the
Master Servicer in respect of its rights and obligations hereunder and access to
officers of the Master Servicer responsible for such obligations. Upon request,
the Master Servicer shall furnish to the Trustee and the NIMS Insurer its most
recent publicly available financial statements and such other information
relating to its capacity to perform its obligations under this Agreement.

          (b) then, and in each and every such case, so long as a Master
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

NIMS Insurer, terminate all of the rights and obligations of the Master 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 Master Servicer, (y) in the

in the case of (v) above, the Trustee shall, at the direction of the NIMS

be given to each Rating Agency, the Depositor and the Originator. On or after
the receipt by the Master Servicer (and by the Trustee if such notice is given
by the Holders) of such written notice, all authority and power of the Master
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, and the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
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 Master Servicer agrees to cooperate with the Trustee
(or the applicable successor Master Servicer) in effecting the termination of
the responsibilities and rights of the Master Servicer hereunder, including,
without limitation, the delivery to the Trustee of all documents and records
requested by it to enable it to assume the Master 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

Account or any Servicing Account or that have been deposited by the Master
Servicer in such accounts or thereafter received by the Master Servicer with
respect to the Mortgage Loans or any REO Property received by the Master
Servicer. All reasonable costs and expenses (including attorneys' fees) incurred
in connection with transferring the Mortgage Files to the successor Master
Servicer and amending this Agreement to reflect such succession as Master
Servicer pursuant to this Section shall be paid by the predecessor Master
Servicer (or if the predecessor Master Servicer is the Trustee, the initial
Master Servicer) upon presentation of reasonable documentation of such costs and
expenses and to the extent not paid by the Master Servicer, by the Trust.



                                      129

          (c) In connection with any failure by the Master Servicer to make any
remittance required to be made by the Master Servicer to the Distribution
Account pursuant to this Section 7.01 on the day and by the time such remittance
is required to be made under the terms of this Section 7.01 (without giving
effect to any grace or cure period), the Master Servicer shall pay to the
Trustee for the account of the Trustee interest at the Prime Rate on any amount
not timely remitted from and including the day such remittance was required to
be made to, but not including, the day on which such remittance was actually
made.

          SECTION 7.02. Trustee to Act; Appointment of Successor.

          (a) From the time the Master Servicer (and the Trustee, if notice is
sent by the Holders) receives a notice of termination pursuant to Section 7.01
or 6.04, the Trustee (or such other successor Master Servicer as is approved in
accordance with this Agreement) shall be the successor in all respects to the
Master 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 Master
Servicer by the terms and provisions hereof arising on and after its succession.
Notwithstanding the foregoing, the parties hereto agree that the Trustee, in its
capacity as successor Master Servicer, immediately will assume all of the
obligations of the Master Servicer to make advances. Notwithstanding the
foregoing, the Trustee, in its capacity as successor Master Servicer, shall not
be responsible for the lack of information and/or documents that it cannot
obtain through reasonable efforts. It is understood and acknowledged by the
parties hereto that there will be a period of transition (not to exceed 90 days)
before the transition of servicing obligations is fully effective. As
compensation therefor, the Trustee (or such other successor Master Servicer)
shall be entitled to such compensation as the Master 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
Master 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 Master Servicer hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer hereunder;
PROVIDED, that the appointment of any such successor Master Servicer shall be
approved by the NIMS Insurer (such approval not to be unreasonably withheld), as
evidenced by the prior written consent of the NIMS Insurer, and will not result
in the qualification, reduction or withdrawal of the ratings assigned to the
Certificates by the Rating Agencies as evidenced by a letter to such effect from
the Rating Agencies. Pending appointment of a successor to the Master 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 Master 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 appointment of a successor Master
Servicer shall not affect any liability of the predecessor Master Servicer which
may have arisen under this Agreement prior to its termination as Master Servicer
to pay any deductible under an insurance policy pursuant to Section 3.14 or to
indemnify the Trustee or the NIMS Insurer pursuant to Section 6.03), nor shall
any successor Master Servicer be liable for any acts or omissions of the
predecessor Master Servicer or for any breach by such Master Servicer of any of
its representations or warranties contained herein



                                      130
<PAGE>



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. All Servicing Transfer Costs shall be paid by
the predecessor Master Servicer upon presentation of reasonable documentation of
such costs, and if such predecessor Master Servicer defaults in its obligation
to pay such costs, such costs shall be paid by the successor Master Servicer or
the Trustee (in which case the successor Master Servicer or the Trustee, as
applicable, shall be entitled to reimbursement therefor from the assets of the
Trust).

          (b) Any successor to the Master Servicer, including the Trustee, 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 Master Servicer hereunder and a Fidelity Bond
in respect of its officers, employees and agents to the same extent as the
Master Servicer is so required pursuant to Section 3.14.

          SECTION 7.03. Waiver of Defaults.

          The Majority Certificateholders may, on behalf of all
Certificateholders and with the consent of the NIMS Insurer, waive any events
permitting removal of the Master 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 and the consent of the NIMS Insurer. Upon any
waiver of a past default, such default shall cease to exist and any Master
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 and the NIMS Insurer.

          SECTION 7.04. Notification to Certificateholders.

          (a) Upon any termination or appointment of a successor to the Master
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, the NIMS Insurer 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
Master 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 and to the NIMS Insurer
notice of such occurrence unless such default or Master Servicer Event of
Termination shall have been waived or cured.

          SECTION 7.05. Survivability of Master Servicer Liabilities.

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

                                   THE TRUSTEE

          SECTION 8.01. Duties of Trustee.

          The Trustee, prior to the occurrence of a Master Servicer Event of
Termination and after the curing of all Master 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 Master Servicer Event of
Termination has occurred (which has not been cured) of which a Responsible
Officer has 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 man would exercise or use under the circumstances
in the conduct of his 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 will not be responsible for the accuracy or content of any such
resolutions, certificates, statements, opinions, reports, documents or other
instruments. If any such instrument is found not to conform to the requirements
of this Agreement in a material manner the Trustee shall take such action as it
deems appropriate to have the instrument corrected, and if the instrument is not
corrected to the Trustee's satisfaction, the Trustee will provide notice thereof
to the Certificateholders and the NIMS Insurer.

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

          (i) prior to the occurrence of a Master Servicer Event of Termination,
     and after the curing of all such Master 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 personally 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 personally liable with respect to any
     action taken, suffered or omitted to be taken by it in good faith in
     accordance with the direction of the NIMS Insurer or the Majority
     Certificateholders relating to the time, method and place of



                                      133
<PAGE>



     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 Master Servicer to comply with the obligations of the Master Servicer
     referred to in clauses (i) and (ii) of Section 7.01(a) unless a Responsible
     Officer of the Trustee at the Corporate Trust Office obtains actual
     knowledge of such failure or the Trustee receives written notice of such
     failure from the Master Servicer, the NIMS Insurer or the Majority
     Certificateholders.

          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 Master Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

          The Trustee is hereby directed to execute and deliver the Cap Contract
for the benefit of the Trust Fund.

          SECTION 8.02. Certain Matters Affecting the Trustee.

          Except as otherwise provided in Section 8.01:

          (i) the Trustee may request and rely upon, and shall be protected in
     acting or refraining from acting upon, any resolution, Officers'
     Certificate, certificate of auditors or any other certificate, statement,
     instrument, opinion, report, notice, request, consent, order, appraisal,
     bond or other paper or document reasonably believed by it to be genuine and
     to have been signed or presented by the proper party or parties, and the
     manner of obtaining consents and of evidencing the authorization of the
     execution thereof by Certificateholders shall be subject to such reasonable
     regulations as the Trustee may prescribe;

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

          (iii) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Agreement, or to institute, conduct
     or defend any litigation hereunder or in relation hereto, at the request,
     order or direction of any of the Certificateholders or the NIMS Insurer,
     pursuant to the provisions of this Agreement, unless such
     Certificateholders or the NIMS Insurer, as applicable, shall have offered
     to the Trustee 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



                                      134
<PAGE>



     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 personally liable for any action taken,
     suffered or omitted by it in good faith and believed by it to be authorized
     or within the discretion or rights or powers conferred upon it by this
     Agreement;

          (v) prior to the occurrence of a Master Servicer Event of Termination
     and after the curing of all Master 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 NIMS Insurer or 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 Master Servicer or the NIMS
     Insurer (if requested by the NIMS Insurer) or, if paid by the Trustee,
     shall be reimbursed by the Master Servicer or the NIMS Insurer (if
     requested by the NIMS Insurer) upon demand and, if not reimbursed by the
     Master Servicer or the NIMS Insurer (if requested by the NIMS Insurer),
     shall be reimbursed by the Trust. Nothing in this clause (v) shall derogate
     from the obligation of the Master Servicer to observe any applicable law
     prohibiting disclosure of information regarding the Mortgagors;

          (vi) the Trustee shall not be accountable, shall have no liability and
     makes no representation as to any acts or omissions hereunder of the Master
     Servicer until such time as the Trustee may be required to act as Master
     Servicer pursuant to Section 7.02 and thereupon only for the acts or
     omissions of the Trustee as successor Master Servicer;

          (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

          (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 Depositor, 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 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 Master Servicer, or for the use or



                                      135
<PAGE>



application of any funds paid to the Master Servicer in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account by the Master
Servicer. The Trustee shall at no 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 Master 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 Master Servicer pursuant to Section 7.02); the
compliance by the Depositor, the Originator, the Seller or the Master 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
Master 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 Master Servicer (other
than if the Trustee shall assume the duties of the Master Servicer pursuant to
Section 7.02), any Sub-Servicer or any Mortgagor; any action of the Master
Servicer (other than if the Trustee shall assume the duties of the Master
Servicer pursuant to Section 7.02), or any Sub-Servicer taken in the name of
the Trustee; the failure of the Master Servicer or any Sub-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 Master Servicer (other
than if the Trustee shall assume the duties of the Master 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, including,
without limitation, the Trustee's duty to review the Mortgage Files pursuant to
Section 2.01. The Trustee shall have no 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 (unless the Trustee shall have become the successor Master
Servicer).

          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
Originator, the Master Servicer, the Depositor or their Affiliates.

          SECTION 8.05. Trustee Fee and Expenses.

          (a) The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself the Trustee Fee. The Trustee shall be
reimbursed from the Trust Fund for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any of the
provisions of this Agreement (not including expenses, disbursements and advances
incurred or made by the Trustee including the compensation and the expenses and
disbursements of its agents and counsel, in the ordinary course of the Trustee's
performance in accordance with the provisions of this Agreement) up to a limit
of $25,000 per calendar year except



                                      136
<PAGE>



any such expense, disbursement or advance as may arise from its negligence or
bad faith or which is the responsibility of Certificateholders or the Trustee
hereunder. In addition, the Trustee and its officers, directors, employees and
agents shall be entitled to be indemnified for, and held harmless by the Trust
Fund against, any and all losses, liabilities, damages, claims or expenses
incurred in connection with any legal action relating to this Agreement or the
Certificates up to a limit of $600,000 per calendar year, other than (i) any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence of the Trustee in the performance of its duties hereunder or by
reason of the Trustee's reckless disregard of obligations and duties hereunder
or (ii) resulting from a breach of the Master Servicer's obligations and duties
under this Agreement and the Mortgage Loans (for which the Master Servicer shall
indemnify pursuant to Section 8.05(b)). Notwithstanding anything herein to the
contrary, the Trustee shall be reimbursed from the Trust Fund for all Servicing
Transfer Costs without regard to any annual limitations. This section shall
survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

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

          (c) Any amounts payable to the Trustee, or any director, officer,
employee or agent of the Trustee in respect of the indemnification provided by
this Section 8.05, or pursuant to any other right of reimbursement from the
Trust Fund that the Trustee, or any director, officer, employee or agent of the
Trustee, may have hereunder in its capacity as such, may be withdrawn by the
Trustee from the Distribution Account at any time.

          (d) The limitations on the indemnification provided to the Trustee set
forth in Section 8.05(a) above shall remain in effect for so long as any series
of notes issued pursuant to one or more Indentures, as set forth in Section 1.04
remain outstanding.

          SECTION 8.06. Eligibility Requirements for Trustee.

          The Trustee hereunder shall at all times be 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 "Baa3" by Moody's, a long-term debt rating of at least "A-" and a
short-term debt rating of at least "A-1" by S&P, if rated by S&P, 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 and the NIMS Insurer 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



                                      137
<PAGE>



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.

          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 NIMS Insurer, the
Depositor, the Master Servicer and each Rating Agency. Upon receiving such
notice of resignation, the Depositor shall promptly appoint a successor Trustee
acceptable to the NIMS Insurer 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 the NIMS Insurer 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 its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor, the Master Servicer or the NIMS Insurer may
remove the Trustee. If the Depositor, the Master Servicer or the NIMS Insurer
removes the Trustee under the authority of the immediately preceding sentence,
the Depositor, with the consent of the NIMS Insurer, 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 (or the NIMS Insurer upon the failure
of the Trustee to perform its obligations hereunder) may at any time remove the
Trustee by written instrument or instruments delivered to the Master Servicer,
the Depositor and the Trustee; the Depositor shall thereupon use its best
efforts to appoint a successor trustee acceptable to the NIMS Insurer 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 NIMS Insurer, the Depositor, the Master
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 Master Servicer and the
predecessor Trustee shall execute and deliver



                                      138
<PAGE>



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

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 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 and the NIMS Insurer to act as co-trustee or co-trustees, jointly with
the Trustee, or separate trustee or separate trustees, of all or any part of 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 Master Servicer and the Trustee may
consider necessary or desirable. Any such co-trustee or separate trustee shall
be subject to the written approval of the Master Servicer and the NIMS Insurer.
If the Master Servicer and the NIMS Insurer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
the case a Master 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 Master 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:




                                      139
<PAGE>



          (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 Master Servicer hereunder), the Trustee shall be
     incompetent or unqualified to perform such act or acts, in which event such
     rights, powers, duties and obligations (including the holding of title to
     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 Master Servicer and the Trustee, acting jointly and with the
     consent of the NIMS Insurer, may at any time accept the resignation of or
     remove any separate trustee or co-trustee except that following the
     occurrence of a Master 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 Master Servicer and the NIMS Insurer.

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

          SECTION 8.11. 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.




                                      140

          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, 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 Originator, the
Depositor, the Master Servicer, the NIMS Insurer 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. Upon request, the Trustee shall
furnish the Depositor, the Master Servicer, the NIMS Insurer and any requesting
Certificateholder with its most recent financial statements. The Trustee shall
cooperate fully with the Seller, the Originator the Master Servicer, the
Depositor and such Certificateholder and shall make available to the Seller, the
Originator, the Master Servicer, the Depositor, the NIMS Insurer and such
Certificateholder for review and copying such books, documents or records as may
be requested with respect to the Trustee's duties hereunder. The Seller, the
Originator, the Depositor, the Master 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 Master Servicer Event of Termination or other default by the
Master Servicer or the Depositor hereunder shall occur and be continuing, the
Trustee, shall, at the direction of the Majority Certificateholders or the NIMS
Insurer, or may, proceed to protect and enforce its rights and the rights of the
Certificateholders or the NIMS Insurer 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, the NIMS Insurer 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.




                                      141

          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.

                              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 Master 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 Master Servicer in fulfilling its duties
hereunder. The Master 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 each
REMIC created hereunder. The expenses of preparing and filing such returns shall
be borne by the Trustee.

          (e) The Holder of the Class R 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.




                                      143
<PAGE>



          (f) The Trustee, the Master 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 Master 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, the NIMS Insurer and the Master 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, the NIMS Insurer and the Master 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, the NIMS Insurer or the Master 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. Subject
to the foregoing, in the event that a REMIC incurs a state or local tax,
including franchise taxes, as a result of a determination that such REMIC is
domiciled in the State of California for state tax purposes by virtue of the
location of the Master Servicer, the Master Servicer agrees to pay on behalf of
such REMIC when due, any and all state and local taxes imposed as a result of
such a determination, in the event that the Holder of the related Class R
Certificate fails to pay such taxes, if any, when imposed.

          (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 Master Servicer shall enter into any
arrangement by which any REMIC created hereunder will receive a fee or other
compensation for services.




                                      144
<PAGE>



          (k) On or before April 15 of each calendar year beginning in 2004, the
Master Servicer shall deliver to the NIMS Insurer, the Trustee and each Rating
Agency an Officers' Certificate stating the Master Servicer's compliance with
the provisions of this Section 9.01.

          (j) 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.

          SECTION 9.02. Prohibited Transactions and Activities.

          Neither the Depositor, the Master 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 and the NIMS Insurer have
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.

          (a) 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 Master Servicer of its duties and
obligations set forth herein, the Master Servicer shall indemnify the NIMS
Insurer, the Trustee and the Trust Fund against any and all losses, claims,
damages, liabilities or expenses ("Losses") resulting from such negligence;
PROVIDED, HOWEVER, that the Master 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 Class R Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of such Class R Certificate
on which the Master Servicer has relied. The foregoing shall not be deemed to
limit or restrict the rights and remedies of the Holder of such Class R
Certificate now or hereafter existing at law or in equity. Notwithstanding the
foregoing, however, in no event shall the Master 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 Master 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).



                                      145
<PAGE>



          (b) 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 Trustee of its duties and obligations set
forth herein, the Trustee shall indemnify the NIMS Insurer and the Trust Fund
against any and all Losses resulting from such negligence; PROVIDED, HOWEVER,
that the Trustee shall not be liable for any such Losses attributable to the
action or inaction of the Master Servicer, the Depositor or the Holder of such
Class R Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Class R Certificate on which the
Trustee has relied. The foregoing shall not be deemed to limit or restrict the
rights and remedies of the Holder of such Class R Certificate now or hereafter
existing at law or in equity. Notwithstanding the foregoing, however, in no
event shall the Trustee 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 Trustee 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).

                                   TERMINATION

          SECTION 10.01. Termination.

          (a) The respective obligations and responsibilities of the Master
Servicer, the Depositor and the Trustee 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 Master 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 Balances of the Regular Certificates have 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 Master Servicer or the NIMS Insurer 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's, living on the
date hereof.

          The Master Servicer (or if the Master Servicer fails to exercise such
option, the NIMS Insurer) may, at its option (the party exercising such right,
the "Terminator"), terminate this Agreement on any date on which the aggregate
of the Principal Balances of the Mortgage Loans (after giving effect to
scheduled payments of principal due during the related Due Period, to the extent
received or advanced, and unscheduled collections of principal received during
the related Prepayment Period) on such date is equal to or less than 10% of the
sum of the aggregate Principal Balances of the Initial Mortgage Loans on the
Cut-off Date and the Original Pre-Funded Amounts, by purchasing, on the next
succeeding Distribution Date, all of the outstanding Mortgage Loans and REO
Properties at a price equal to the fair market value of the Mortgage Loans and
REO Properties (as determined by the Master Servicer, if it is the Terminator,
the NIMS Insurer, if it is the Terminator and, to the extent that the Class A
Certificates or a Class of Mezzanine Certificates will not receive all amounts
owed to it as a result of the termination, the Trustee, as of the close of
business on the third Business Day next preceding the date upon which notice of
any such termination is furnished to the related Certificateholders pursuant to
Section 10.01(c)), plus accrued and unpaid interest thereon at the weighted
average of the Mortgage Rates through the end of the Due Period preceding the
final Distribution Date plus unreimbursed Servicing Advances, Advances, any
unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties, any
accrued and unpaid Net WAC Rate Carryover Amount (the "Termination Price");
provided, however, such option may only be exercised if (i) the Termination
Price is sufficient to pay all interest accrued on, as well as amounts necessary
to retire the principal balance of, each class of notes secured primarily by the
Class C Certificates and the Class P Certificates and issued pursuant to the
Indenture and any amounts owed to the NIMS Insurer at the time the option is
exercised, and (ii) the fair market value of the Mortgage Loans and REO
Properties determined as provided above is at least equal to the Principal
Balance of the Mortgage Loans (after giving effect to scheduled payments of
principal due during the related Due Period, to the extent received or advanced,
and unscheduled collections of principal received during the related Prepayment
Period) and the appraised value of the REO Properties. Notwithstanding the
foregoing, if the condition set forth in clause (i) above is satisfied but the
condition set forth in clause (ii) above is not satisfied, then if the
Terminator is the Master



                                      147
<PAGE>



Servicer, such Terminator may nevertheless exercise such option by paying a
higher Termination Price equal to the Principal Balance of the Mortgage Loans
(after giving effect to scheduled payments of principal due during the related
Due Period, to the extent received or advanced, and unscheduled collections of
principal received during the related Prepayment Period) and the appraised value
of the REO Properties plus accrued and unpaid interest thereon at the weighted
average of the Mortgage Rates through the end of the Due Period preceding the
final Distribution Date plus unreimbursed Servicing Advances, Advances, any
unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties, any
accrued and unpaid Net WAC Rate Carryover Amount, provided that the payment of
such higher Termination Price is not prohibited by any regulatory institution
under whose supervision such Terminator may be conducting its business at such
time.

          In connection with any such purchase pursuant to the preceding
paragraph, the Master Servicer or the NIMS Insurer, as applicable, shall deposit
in the Distribution Account all amounts then on deposit in the Collection
Account, which deposit shall be deemed to have occurred immediately preceding
such purchase.

          Any such purchase shall be accomplished by deposit into the
Distribution Account 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 Master Servicer
or the NIMS Insurer, by letter to the Certificateholders and the NIMS Insurer
mailed not earlier than the 15th day and not later than the 25th day of the
month next preceding 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 Section 4.01 for such
Distribution Date. By acceptance of the Class R Certificates, the Holders of the
Class R Certificates agree, in connection with any termination hereunder, to
assign and transfer any amounts in excess of the par value of the Mortgage
Loans, and to the extent received in respect of such termination, to pay any
such amounts to the Holders of the Class C Certificates.

          (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 Servicing Account for
the benefit of such Certificateholders, and



                                      148
<PAGE>



the Master Servicer (if the Master Servicer has exercised its right to purchase
the Mortgage Loans), the NIMS Insurer (if the NIMS Insurer 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 after the second notice all the
Certificates shall not have been surrendered for cancellation, the Class R
Certificateholder shall be entitled to all unclaimed funds and other assets
which remain subject hereto, and the Trustee upon transfer of such funds shall
be discharged of any responsibility for such funds, and the Certificateholders
shall look to the Class R Certificateholder for payment.

          SECTION 10.02. Additional Termination Requirements.

          (a) In the event that the Master Servicer or the NIMS Insurer
exercises its purchase option as provided in Section 10.01, each REMIC 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:

          (i) Within 90 days prior to the final Distribution Date, the Master
     Servicer or the NIMS Insurer shall adopt and the Trustee shall sign a plan
     of complete liquidation of each REMIC created hereunder meeting the
     requirements of a "Qualified Liquidation" under Section 860F of the Code
     and any regulations thereunder; and

          (ii) At or after the time of adoption of such a plan of complete
     liquidation and at or prior to the final Distribution Date, the Trustee
     shall sell all of the assets of the Trust Fund to the Master Servicer or
     the NIMS Insurer, as applicable, for cash pursuant to the terms of the plan
     of complete liquidation.

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

                            MISCELLANEOUS PROVISIONS

          SECTION 11.01. Amendment.

          This Agreement may be amended from time to time by the Depositor, the
Master Servicer and the Trustee with the consent of the NIMS Insurer 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(b) 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 that such action shall not, as evidenced by either (a) an
Opinion of Counsel delivered to the Trustee or (b) written notice to the
Depositor, the Master 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,
adversely affect in any material respect the interests of any Certificateholder.
Neither an Opinion of Counsel nor confirmation from the Rating Agencies will be
required in connection with an amendment to the provisions of Section 3.22(b).
No amendment shall be deemed to adversely affect in any material respect the
interests of any Certificateholder who shall have consented thereto, and no
Opinion of Counsel or written notice from the Rating Agencies shall be required
to address the effect of any such amendment on any such consenting
Certificateholder.

          This Agreement may also be amended from time to time by the Depositor,
the Master Servicer and the Trustee with the consent of the NIMS Insurer and the
Holders of Certificates entitled to at least 66% of the Voting Rights for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of
the Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments received on
Mortgage Loans which are required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) adversely affect in any
material respect the interests of the Holders of any Class of Certificates (as
evidenced by either (a) an Opinion of Counsel delivered to the Trustee or (b)
written notice to the Depositor, the Master Servicer and the Trustee from the
Rating Agencies that such action will not result in the reduction or withdrawal
of the rating of any outstanding Class of Certificates with respect to which it
is a Rating Agency) in a manner, other than as described in (i), or (iii) modify
the consents required by the immediately preceding clauses (i) and (ii) without
the consent of the Holders of all Certificates then outstanding. Notwithstanding
any other provision of this Agreement, for purposes of the giving or withholding
of consents pursuant to this Section 11.01, Certificates registered in the name
of the Depositor or the Master Servicer or any Affiliate thereof shall be
entitled to Voting Rights with respect to matters affecting such Certificates.

          Notwithstanding any 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 and satisfactory to the NIMS Insurer, to the
effect that such amendment will not result in the imposition of a tax on any
REMIC created hereunder constituting part of the Trust Fund pursuant to the
REMIC Provisions



                                      150
<PAGE>



or cause any REMIC created hereunder 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 Master 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 Master
Servicer, the NIMS Insurer 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.

          The Trustee may, but shall not be obligated to, enter into any
amendment pursuant to this Section 11.01 that affects its rights, duties and
immunities under this Agreement or otherwise.

          SECTION 11.02. Recordation of Agreement; Counterparts.

          To the extent permitted by applicable law, this Agreement is subject
to recordation in all appropriate public offices for real property records in
all the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Master Servicer at the expense of the 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



                                      151
<PAGE>



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 hereinbefore 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.

          SECTION 11.04. Governing Law; Jurisdiction.

          This Agreement shall be construed in accordance with the laws of the
State of New York, and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws. With respect to any
claim arising out of this Agreement, each party irrevocably submits to the
exclusive jurisdiction of the courts of the State of New York and the United
States District Court located in the Borough of Manhattan in The City of New
York, and each party irrevocably waives any objection which it may have at any
time to the laying of venue of any suit, action or proceeding arising out of or
relating hereto brought in any such courts, irrevocably waives any claim that
any such suit, action or proceeding brought in any such court has been brought
in any inconvenient forum and further irrevocably waives the right to object,
with respect to such claim, suit, action or proceeding brought in any such
court, that such court does not have jurisdiction over such party, provided that
service of process has been made by any lawful means.

waiver or other action provided by this Agreement to be given or taken by the
Certificateholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Certificateholders in person or by
agent duly appointed in writing, and such action shall become effective when
such instrument or instruments are delivered to the Trustee and the Master
Servicer. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "act" of the
Certificateholders signing such instrument or instruments. Proof of execution of
any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Agreement and conclusive in favor of the

individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

          (c) Any request, demand, authorization, direction, notice, consent,
waiver or other action by any Certificateholder shall bind every future Holder

Trust in reliance thereon, whether or not notation of such action is made upon

          The Depositor, Master Servicer and the Trustee, by entering into this

Agreement.

     This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2003-4, Asset-Backed Certificates,
Series 2003-4 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Trustee.

     Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day then the first
Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified 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 therefor 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, but with the consent of the NIMS Insurer, if any.

     As provided in the Agreement and subject to certain limitations therein set
forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
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 and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if any,
the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, 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 hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

     On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in July 2033.

     Capitalized terms used herein that are defined in the Agreement shall have
the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Trustee.

     Pursuant to the terms of the Agreement, a distribution will be made on the

to Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the

manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified 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 therefor 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, but with the consent of the NIMS Insurer, if any.

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

     Principal in respect of this Certificate is distributable monthly as set
forth herein. Accordingly, the Certificate Principal Balance of this Class M-1
Certificate at any time may be less than the Initial Certificate Principal
Balance set forth on the face hereof, as described herein. This Class M-1
Certificate does not evidence an obligation of, or an interest in, and is not
guaranteed by the Depositor, the Master Servicer, or the Trustee referred to
below or any of their respective affiliates.

     This certifies that Cede & Co. is the registered owner of the Percentage
Interest evidenced by this Class M-1 Certificate (obtained by dividing the
Denomination of this Class M-1 Certificate by the Original Class Certificate
Principal Balance) in certain monthly distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Option One Mortgage
Acceptance Corporation (the "Depositor"). The Trust was created pursuant to a
Pooling and Servicing Agreement dated as of June 1, 2003 (the "Agreement") among
the Depositor, Option One Mortgage Corporation, as master servicer (the "Master
Servicer"), and Wells Fargo Bank Minnesota, National Association, a national
banking association, as Trustee (the "Trustee"). To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Agreement. This Class M-1 Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Class M-1 Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

     Each Transferee of this Certificate will be deemed to have represented by
virtue of its purchase or holding of such Certificate (or interest therein) that
either (a) such Transferee is not a Plan or purchasing such Certificate with
Plan Assets, (b) it has acquired and is holding such Certificate in reliance on
the Prohibited Transaction Exemption (the "Exemption") set forth in the
Agreement and that it understands that there are certain conditions to the
availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

     Reference is hereby made to the further provisions of this Class M-1
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

     This certifies that Cede & Co. is the registered owner of the Percentage

Agreement. This Class M-4 Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Class M-4 Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

     Each Transferee of this Certificate will be deemed to have represented by
virtue of its purchase or holding of such Certificate (or interest therein) that
either (a) such Transferee is not a Plan or purchasing such Certificate with
Plan Assets, (b) it has acquired and is holding such Certificate in reliance on
the Prohibited Transaction Exemption (the "Exemption") set forth in the
Agreement and that it understands that there are certain conditions to the
availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

     Reference is hereby made to the further provisions of this Class M-4
Certificate set forth on the reverse hereof, which further provisions shall for

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, but with the consent of the NIMS Insurer, if any.

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

transfer at the office or agency maintained by the Trustee accompanied by a
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 and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are

the Certificate Registrar, any Paying Agent and any agent of the Master

Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

     On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will

Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in July 2033.

     Principal in respect of this Certificate is distributable monthly as set

     This certifies that Cede & Co. is the registered owner of the Percentage

Agreement. This Class M-5F Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Class M-5F Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

     Each Transferee of this Certificate will be deemed to have represented by
virtue of its purchase or holding of such Certificate (or interest therein) that
either (a) such Transferee is not a Plan or purchasing such Certificate with
Plan Assets, (b) it has acquired and is holding such Certificate in reliance on
the Prohibited Transaction Exemption (the "Exemption") set forth in the
Agreement and that it understands that there are certain conditions to the
availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

     Reference is hereby made to the further provisions of this Class M-5F
Certificate set forth on the reverse hereof, which further provisions shall for

     evidencing the Percentage Interest in the distributions allocable to the
     Certificates of the above-referenced Class with respect to the Trust
     consisting of first and second lien, adjustable and fixed rate mortgage
     loans (the "Mortgage Loans")

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

     Principal in respect of this Certificate is distributable monthly as set
forth herein. Accordingly, the Certificate Principal Balance of this Class C
Certificate at any time may be less than the Initial Certificate Principal
Balance set forth on the face hereof, as described herein. This Class C
Certificate does not evidence an obligation of, or an interest in, and is not
guaranteed by the Depositor, the Master Servicer, or the Trustee referred to
below or any of their respective affiliates.

     This certifies that Option One Mortgage Corporation is the registered owner
of the Percentage Interest evidenced by this Class C Certificate (obtained by
dividing the Denomination of this Class C Certificate by the Original Class
Certificate Principal Balance) in certain distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Option One Mortgage
Acceptance Corporation (the "Depositor"). The Trust was created pursuant to a
Pooling and Servicing Agreement dated as of June 1, 2003 (the "Agreement") among
the Depositor, Option One Mortgage Corporation, as master servicer (the "Master
Servicer"), and Wells Fargo Bank Minnesota, National Association, a national
banking association, as Trustee (the "Trustee"). To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Agreement. This Class C Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Class C Certificate by virtue of the acceptance hereof assents and by which
such Holder is bound.

     No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor certificate by the transferor and an investment letter
shall be executed by the transferee. The Holder hereof desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee and the
Depositor 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.

     Principal in respect of this Certificate is distributable monthly as set
forth herein. Accordingly, the Certificate Principal Balance of this Class P
Certificate at any time may be less than the Initial Certificate Principal

Certificate Principal Balance) in certain distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Option One Mortgage

such Holder is bound.

     This Certificate does not have a pass-through rate and will be entitled to
distributions only to the extent set forth in the Agreement.

transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor certificate by the transferor and an investment letter
shall be executed by the transferee. The Holder hereof desiring to effect such
transfer shall, and

does hereby agree to, indemnify the Trustee and the Depositor 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.

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

the title insurance or escrow company, with the original or a certified copy

     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 deliver such missing document to the Purchaser.
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 pursuant to Section 2.03 of the Pooling and Servicing Agreement.

     The Purchaser hereby acknowledges its acceptance of all right, title and
interest to the Mortgage Loans and other property, now existing and hereafter
created, conveyed to it pursuant to Section 2.01.

     The parties hereto intend that the transaction set forth herein be a sale

obligations hereunder; and this Agreement shall constitute a security agreement
under applicable law.

     The Seller shall cause the Assignments which were delivered in blank to be

hereof and, to the extent necessary, in Section 2.02(iv) hereof to be recorded.
The Seller shall be required to deliver such Assignments for recording within 90
days of the Closing Date. Notwithstanding the foregoing, however, for
administrative convenience and facilitation of servicing and to reduce closing
costs, the Assignments of Mortgage shall not be required to be submitted for
recording with respect to any Mortgage Loan in any jurisdiction where the Rating
Agencies do not require recordation in order to receive the ratings on the
Certificates at the time of their initial issuance; PROVIDED, HOWEVER, each
Assignment shall be submitted for recording by the Seller in the manner
described above, at no expense to the Trust Fund or Trustee, upon the earliest
to occur of: (i) reasonable direction by Holders of Certificates entitled to at
least 25% of the Voting Rights, or the NIMS Insurer, (ii) the occurrence of a
Master Servicer Event of Termination, (iii) the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Master Servicer, (iv) the occurrence
of a servicing transfer as described in Section 7.02 hereof, (v) if the Seller
is not the Master Servicer and with respect to any one Assignment the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Mortgagor under the
related Mortgage and (vi) any Mortgage Loan that is 90 days or more Delinquent.
Upon (a) receipt of written notice from the Trustee that recording of the
Assignments is required pursuant to one or more of


                                        4

<PAGE>


the conditions (excluding (v) and (vi) above) set forth in the preceding
sentence or (b) upon the occurrence of condition (v) or (vi) in the preceding
sentence, the Seller shall be required to deliver such Assignments for recording
as provided above, promptly and in any event within 30 days following receipt of
such notice. Notwithstanding the foregoing, if the Seller fails to pay the cost
of recording the Assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust. The Seller shall
furnish the Trustee, or its designated agent, with a copy of each Assignment
submitted for recording. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Seller 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. In the event that
any Mortgage Note is endorsed in blank as of the Closing Date, within ninety
(90) days of the Closing Date the Seller shall cause to be completed such
endorsements "Pay to the order of Wells Fargo Bank Minnesota, National
Association, as Trustee, without recourse."

     The Seller shall forward to the Purchaser original documents evidencing an
assumption, modification, consolidation or extension of any Mortgage Loan
entered into in accordance with the Pooling and Servicing Agreement within two
weeks of their execution; PROVIDED, HOWEVER, that the Seller shall provide the
Purchaser with a certified true copy of any such document submitted for
recordation within two weeks of its execution, and shall provide the original of
any document submitted for recordation or a copy of such document certified by
the appropriate public recording office to be a true and complete copy of the
original within 365 days of its submission for recordation. In the event that
the Seller cannot provide a copy of such document certified by the public
recording office within such 365 day period, the Seller shall deliver to the
Purchaser, within such 365 day period, an Officer's Certificate of the Master
Servicer which shall (A) identify the recorded document, (B) state that the
recorded document has not been delivered to the Purchaser due solely to a delay
caused by the public recording office, (C) state the amount of time generally
required by the applicable recording office to record and return a document
submitted for recordation, if known, and (D) specify the date the applicable
recorded document is expected to be delivered to the Purchaser, and, upon
receipt of a copy of such document certified by the public recording office, the
Seller shall immediately deliver such document to the Purchaser. In the event
the appropriate public recording office will not certify as to the accuracy of
such document, the Seller shall deliver a copy of such document certified by an
officer of the Seller to be a true and complete copy of the original to the
Purchaser.

<PAGE>


enforcement may be limited by bankruptcy, insolvency, reorganization or other
similar laws affecting the enforcement of creditors' rights generally and by
general equity principles (regardless of whether such enforcement is considered
in a proceeding in equity or at law);

          (g) The related Mortgage is a valid and enforceable first or second
lien on the related Mortgaged Property, which Mortgaged Property is free and
clear of all encumbrances and liens (including mechanics liens) having priority
over the first or second lien of the Mortgage except for: (i) liens for real
estate taxes and assessments not yet due and payable; (ii) covenants, conditions

reflected or considered in the lender's title insurance policy delivered to the
originator of the Mortgage Loan and referred to in the appraisal made in
connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

          (h) Any security agreement, chattel mortgage or equivalent document
related to such Mortgage Loan establishes and creates a valid and enforceable
first or second lien on the Mortgaged Property;

          (i) As of the last calendar day of May 2003 and with respect to any
Mortgage Loan that had a payment due on or before May 1, 2003, except with
respect to 84.93% of the Mortgage Loans by the aggregate Cut-off Date Principal
Balance of the Mortgage Loans, the related Monthly Payment due on May 1, 2003
has been received. In addition, 0.55% of the Mortgage Loans have been 30 or more
days delinquent in the last 12 months and 0.15% of the Mortgage Loans have been
30 or more days delinquent for two payment periods in the last 12 months;

          (j) The Seller has not advanced funds, or induced, solicited or

part (except for a release that does not materially impair the security of the
Mortgage Loan or a release the effect of which is reflected in the Loan-to-Value
Ratio or combined Loan-to-Value Ratio for the Mortgage Loan as set forth in the
Schedule of Mortgage Loans), nor has any instrument been executed that would
effect any such release, cancellation, subordination or rescission;



                                        7

<PAGE>


          (m) No Mortgage Loan is 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 any Mortgage Note or Mortgage, or the exercise of any
right thereunder, render either the Mortgage Note or 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;

          (n) To the Seller's knowledge, there is no proceeding pending for the
total or partial condemnation and no eminent domain proceedings pending
affecting any Mortgaged Property;

          (o) Each Mortgage Loan is covered by either (i) a mortgage title
insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged Property is
located, an attorney's opinion of title given by an attorney licensed to
practice law in the jurisdiction where the Mortgaged Property is located. All of
the Seller's rights under such policies, opinions or other instruments shall be
transferred and assigned to Purchaser upon sale and assignment of the Mortgage
Loans hereunder. The title insurance policy has been issued by a title insurer
licensed to do business in the jurisdiction where the Mortgaged Property is
located, insuring the original lender, its successor and assigns, as to the
first or second priority lien of the Mortgage in the original principal amount
of the Mortgage Loan, subject to the exceptions contained in such policy. The
Seller is the sole insured of such mortgagee title insurance policy, and such
mortgagee title insurance policy is in full force and effect and will be in
force and effect upon the consummation of the transactions contemplated by this
Agreement. Neither the Seller nor any affiliate of the Seller has made, and the
Seller has no knowledge of, any claims under such mortgagee title insurance
policy. The Seller is not aware of any action by a prior holder and neither the
Seller nor any affiliate of the Seller has done, by act or omission, anything
which could impair the coverage or enforceability of such mortgagee title
insurance policy or the accuracy of such attorney's opinion of title;

          (p) There is no material default, breach, violation or event of
acceleration existing under the related Mortgage or the related 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 material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Seller nor any
affiliate of the Seller has waived any default, breach, violation or event of
acceleration;

          (q) With respect to any Mortgage Loan which provides for an adjustable
interest rate, all rate adjustments have been performed in accordance with the
terms of the related Mortgage Note or subsequent modifications, if any;

          (r) To the Seller's knowledge, there are no delinquent taxes, ground
rents, water charges, sewer rents, assessments, insurance premiums, leasehold
payments, including assessments payable in future installments or other
outstanding charges, affecting the related Mortgaged Property;



                                       8
<PAGE>

          (s) No foreclosure proceedings are pending against the Mortgaged
Property and the Mortgage Loan is not subject to any pending bankruptcy or
insolvency proceeding, and to the Seller's best knowledge, no material
litigation or lawsuit relating to the Mortgage Loan is pending;

          (t) The Mortgage Loan obligates the mortgagor thereunder to maintain a
hazard insurance policy ("Hazard Insurance") in an amount at least equal to the
lesser of (i) the maximum insurable value of such improvements or (ii) the
principal balance of the Mortgage Loan with a standard mortgagee clause, in
either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

          (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

          (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
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 (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Seller or any affiliate of the Seller and the
Seller has no knowledge of any relief requested or allowed to the Mortgagor
under the Soldiers and Sailors Civil Relief Act of 1940;

          (w) Except as set forth in the appraisal which forms part of the
related Mortgage File, the Mortgaged Property, normal wear and tear excepted, is
undamaged by waste, fire, earthquake or earth movement, windstorm, flood,
tornado or other casualty so as to affect materially and adversely the value




                                       9
<PAGE>

of the Mortgaged Property as security for the Mortgage Loan or the use for which
the premises were intended;

          (x) To the Seller's knowledge, there was no fraud involved in the
origination of the Mortgage Loan by the mortgagee or by the Mortgagor, any
appraiser or any other party involved in the origination of the Mortgage Loan;

          (y) Each Mortgage File contains an appraisal of the 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
performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

          (z) To the best of the Seller's knowledge, all parties which have had
any interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee or
otherwise, are (or, during the period in which they held and disposed of such
interest, were) in compliance with any and all applicable "doing business" and
licensing requirements of the laws of the state wherein the Mortgaged Property
is located;

          (aa) No improvements on the related Mortgaged Property (upon which
value was given) 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 the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

          (bb) Each Mortgage Loan was originated or acquired by a savings and
loan association, a savings bank, a commercial bank or similar banking
institution which is supervised and examined by a federal or state authority, or
by a mortgagee approved by the Secretary of HUD. Each Mortgage Loan was
originated substantially in accordance with the Seller's underwriting criteria,
which are at least as stringent as the underwriting criteria set forth in the
Prospectus Supplement. Each Mortgage Loan is currently being serviced by the
Seller and has been serviced by the Seller since the date of origination of such
Mortgage Loan;

          (cc) (i) Principal payments on the Mortgage Loan commenced no more
than two months after the proceeds of the Mortgage Loan were disbursed and (ii)
each Mortgage Note is payable on the first day of each month;

          (dd) Other than, approximately less than 1% of the Mortgage Loans (by
aggregate principal balance of the Mortgage Loans as of the Cut-off Date), which
are "balloon payment" mortgage loans, each Mortgage Loan is fully amortizing;

          (ee) The Mortgage Loan bears interest at the Mortgage Rate and the
Mortgage Note does not permit negative amortization. No Mortgage Loan bearing
interest at an adjustable rate permits the Mortgagor to convert the Mortgage
Loan to a fixed rate Mortgage Loan;



                                       10
<PAGE>

          (ff) With respect to escrow deposits, if any, all such payments are in
the possession of, or under the control of, the Master Servicer and there exist
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 Master Servicer have been capitalized under
any Mortgage or the related Mortgage Note;

          (gg) No Mortgage Loan contains provisions pursuant to which scheduled
payments are: (i) paid or partially paid with funds deposited in any separate
account established by the Seller, the Mortgagor, or anyone on behalf of the
Mortgagor; or (ii) paid by any source other than the Mortgagor or 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;

          (hh) As of the origination date of each Mortgage Loan, the related
Mortgaged Property is lawfully permitted to be occupied under applicable law;

          (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note;

          (jj) No Mortgage Loan was made in connection with (a) the construction
or rehabilitation of a Mortgaged Property or (b) facilitating the trade-in or
exchange of a Mortgaged Property;

          (kk) 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;

          (ll) There are no mechanics' or similar liens or claims that 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 that are
or may be liens prior to, or equal or coordinate with, the lien of the related
Mortgage;

          (mm) As to each Mortgage Loan, interest is calculated on the Mortgage
Note on the basis of twelve 30-day months and a 360 day year;



                                       11
<PAGE>

          (nn) The Mortgaged Property consists of one of the following: detached
or semi-detached one-to four-family dwelling units, townhouses, individual
condominium units and individual units in planned unit developments, or
manufactured homes;

          (oo) Each Mortgage Loan constitutes a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code;

          (pp) The Mortgage Loans were not intentionally selected by the Seller
in a manner intended to adversely affect the Purchaser or the Trust;

          (qq) The representations, warranties and covenants, set forth in this
Section shall survive the Closing Date;

          (rr) The Mortgage Loans have original terms to maturity ranging from
10 to 30 years;

          (ss) With respect to the Mortgage Loans, no more than 18.78%; 10.15%;
8.87%, 5.91% and 5.63% of the Mortgage Loans, by Cut-off Date Principal Balance
will be secured by Mortgaged Properties located in California, New York,
Florida, Washington and Michigan, respectively; and 83.84% of the Mortgage
Loans, by Cut-off Date Principal Balance will be secured by real property with a
single family residence erected thereon and approximately 5.16% of the Mortgage
Loans, by the Cut-off Date Principal Balance are secured by condominiums;

          (tt) As of the Cut-off Date, each Mortgage Loan had a
Loan-to-Value-Ratio that was less than or equal to 97.57%;

          (uu) With respect to each Mortgage Loan, the Mortgage Note related
thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which will be
adjusted on each Adjustment Date to equal the Index plus the Gross Margin,
rounded to the nearest or next highest 0.125%, subject to the Periodic Rate Cap,
the Maximum Mortgage Rate and the Minimum Mortgage Rate;

          (vv) The average Cut-off Date Principal Balance of the Mortgage Loans
is $140,160.85;

          (ww) No Mortgage Loan is subject to the requirements of the Home
Ownership and Equity Protection Act of 1994 ("HOEPA"), nor any state law,
ordinance or regulation similar to HOEPA;

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

          (yy) No Mortgage Loan originated before October 1, 2002 has a
Prepayment Charge term longer than five years after its origination and no
Mortgage Loan originated on or after October 1, 2002 has a Prepayment Charge
term longer than three years after its origination;



                                       12
<PAGE>

          (zz) Each Group I Mortgage Loan had a Principal Balance at origination
which conformed with Fannie Mae/Freddie Mac guidelines.

          (aaa) Each Mortgage Loan conforms, and all Mortgage Loans in the
aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

          (bbb) With respect to second lien Mortgage Loans, either (a) no
consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File; and

          (ccc) Each Mortgage Note is comprised of one original promissory note
and each such promissory note constitutes an "instrument" for purposes of
section 9-102(a)(65) of the UCC;

          (ddd) [Reserved];

          (eee) No borrower was encouraged or required to select a Group I
Mortgage Loan product offered by the Originator which is a higher cost product
designed for less creditworthy borrowers, unless at the time of the Group I
Mortgage Loan's origination, such borrower did not qualify taking into account
credit history and debt-to-income ratios for a lower-cost credit product then
offered by the Originator or any affiliate of the Originator. If, at the time of
loan application, the borrower may have qualified for a for a lower-cost credit
product then offered by any mortgage lending affiliate of the Originator, the
Originator referred the borrower's application to such affiliate for
underwriting consideration;

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

          (ggg) With respect to any Group I Mortgage Loan that contains a
provision permitting imposition of a premium upon a prepayment prior to

premium in exchange for a monetary benefit, including but not limited to a rate
or fee reduction, (ii) prior to the loan's origination, the borrower was offered
the choice of another mortgage product that did not require payment of such a
premium, (iii) the prepayment premium is disclosed to the borrower in the loan
documents pursuant to applicable state and federal law, and (iv) notwithstanding
any state or federal law to the contrary, the Master Servicer shall not impose
such prepayment premium in any instance when the mortgage debt is accelerated as
the result of the borrower's default in making the loan payments;



                                       13
<PAGE>

          (hhh) No borrower of a Group I Mortgage Loan was required to purchase
any credit life, disability, accident or health insurance product as a condition
of obtaining the extension of credit. No borrower obtained a prepaid
single-premium credit life, disability, accident or health insurance policy in
connection with the origination of a Group I Mortgage Loan;

          (iii) All points and fees related to each Group I Mortgage Loan were
disclosed in writing to the borrower in accordance with applicable state and
federal law. Except in the case of a Group I Mortgage Loan in an original
principal amount of less than $60,000 which would have resulted in an
unprofitable origination, no borrower was charged "points and fees" (whether or
not financed) in an amount greater than 5% of the principal amount of such loan,
such 5% limitation calculated in accordance with the Lender Letter. All fees and
charges (including finance charges) and whether or not financed, assessed,
collected or to be collected in connection with the origination and servicing of
each Group I Mortgage Loan has been disclosed in writing to the borrower in
accordance with applicable state and federal law and regulation; and

          (lll) Each Group I Mortgage Loan is in compliance with the
anti-predatory lending eligibility for purchase requirements of the Fannie Mae
Lender Letter, LL03-00: Eligibility of Mortgages to Borrowers with Blemished
Credit Records (04/11/00) other than the requirements regarding Escrow Deposit
Accounts;

          (mmm) No Group I Mortgage Loan is a "High Cost Home Loan" as defined

Mortgage Loans was in the ordinary course of business of the Seller and the
assignment and conveyance of the Mortgage Notes and the Mortgages by the Seller
are not subject to the bulk transfer or any similar statutory provisions;

          (x) The information delivered by the Seller to the Purchaser with
respect to the Seller's loan loss, foreclosure and delinquency experience on
mortgage loans underwritten to similar standards as the Mortgage Loans and
covering mortgaged properties similar to the Mortgaged Properties, is true and
correct in all material respects as of the date of such report;

          (xi) Except with respect to any statement regarding the intentions of
the Purchaser, or any other statement contained herein the truth or falsity of
which is dependant solely upon the actions of the Purchaser, this Agreement does
not contain any untrue statement of material fact or omit to state a material
fact necessary to make the statements contained herein not misleading. The
written statements, reports and other documents prepared and furnished or to be
prepared and furnished by the Seller pursuant to this Agreement or in connection
with the transactions contemplated hereby taken in the aggregate do not contain
any untrue statement of material fact or omit to state a material fact necessary
to make the statements contained therein not misleading; and

          (xii) The Seller has not transferred the Mortgage Loans with any
intent to hinder, delay or defraud any of its creditors.

     Section 3.03 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It is
understood and agreed that the representations and warranties set forth in
Sections 3.01 and 3.02 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Seller or as to which the Seller has no knowledge,
if it is discovered that the substance of any such representation and warranty
is inaccurate and the inaccuracy materially and adversely affects the value of
the related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, 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 and warranty was made,
such inaccuracy shall be deemed a breach of the applicable representation and
warranty and the Seller shall take such action described in the following
paragraphs of this Section 3.03 in respect of such Mortgage Loan. Upon discovery
by either the Seller, the Master Servicer or the Purchaser of a breach of any of
the foregoing representations and warranties that materially and adversely
affects the value of the Mortgage Loans or the interest of the Purchaser (or
which materially and adversely affects the interests of the Purchaser in the
related Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others. It is understood by the parties hereto that a
breach of the representations and warranties made in Section 3.01(ww), (xx) and
(jjj) will be deemed to materially and adversely affect the value of the related
Mortgage Loan or the interest of the Purchaser.



                                       16

     Within 120 days of the earlier of either discovery by or notice to the
Seller of any breach of a representation or warranty made by the Seller that
materially and adversely affects the value of a Mortgage Loan or the Mortgage
Loans or the interest therein of the Purchaser, the Seller shall use its best
efforts promptly to cure such breach in all material respects and, if such
breach cannot be cured, the Seller shall, at the Purchaser's option, repurchase
such Mortgage Loan at the Purchase Price. In the event that a breach shall
involve any representation or warranty set forth in Section 3.02 and such breach
cannot be cured within 120 days of the earlier of either discovery by or notice
to the Seller of such breach, each Mortgage Loan shall, at the Purchaser's
option, be repurchased by the Seller at the Purchase Price, as such term is
defined in the Pooling and Servicing Agreement. The Seller may, at the request
of the Purchaser and assuming the Seller has a Qualified Substitute Mortgage
Loan, rather than repurchase a deficient Mortgage Loan as provided above, remove
such Mortgage Loan and substitute in its place a Qualified Substitute Mortgage
Loan or Loans. If the Seller does not provide a Qualified Substitute Mortgage
Loan or Loans, it shall repurchase the deficient Mortgage Loan. Any repurchase
of a Mortgage Loan(s) pursuant to the foregoing provisions of this Section 3.03
shall occur on a date designated by the Purchaser and shall be accomplished by
deposit in accordance with Section 2.03 of the Pooling and Servicing Agreement.
Any repurchase or substitution required by this Section shall be made in a
manner consistent with Section 2.03 of the Pooling and Servicing Agreement.

     At the time of substitution or repurchase of any deficient Mortgage Loan,
the Purchaser and the Seller shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Seller and the delivery to the
Seller of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Seller shall, simultaneously with such deposit, give
written notice to the Purchaser that such deposit has taken place. Upon such
repurchase, the Mortgage Loan Schedule shall be amended to reflect the
withdrawal of the repurchased Mortgage Loan from this Agreement.

     As to any Deleted Mortgage Loan for which the Seller substitutes a
Qualified Substitute Mortgage Loan or Loans, the Seller shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing Agreement, with the Mortgage Note endorsed as required
therein. The Seller shall deposit in the Collection Account the Monthly Payment
less the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans
in the month following the date of such substitution. Monthly Payments due with
respect to Qualified Substitute Mortgage Loans in the month of substitution will
be retained by the Seller. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Seller shall thereafter be entitled to retain
all amounts subsequently received by the Seller in respect of such Deleted
Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage Loans
shall be subject to the terms of this Agreement in all respects, and the Seller
shall be deemed to have made with respect to such Qualified Substitute Mortgage
Loan or Loans as of the date of substitution, the covenants, representations and
warranties set forth in Sections 3.01 and 3.02.

     It is understood and agreed that the representations and warranties set
forth in Section 3.01 shall survive delivery of the respective Mortgage Files to
the Trustee on behalf of the Purchaser.



                                       17
<PAGE>

     It is understood and agreed that the obligations of the Seller set forth in
Section 3.03 to cure, repurchase and substitute for a defective Mortgage Loan
and to indemnify the Purchaser as provided in Section 5.01 constitute the sole
remedies of the Purchaser respecting a missing or defective document or a breach
of the representations and warranties contained in Section 3.01 or 3.02.

                                   ARTICLE IV.

                               SELLER'S COVENANTS

     Section 4.01 COVENANTS OF THE SELLER. 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
under the Mortgage Loans, against all claims of third parties claiming through
or under the Seller or 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.

                                   ARTICLE V.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS

     Section 5.01 INDEMNIFICATION.

          (a) The Seller agrees to indemnify and hold harmless the Purchaser,
each of its directors, each of its officers and each person or entity who
controls the Purchaser or any such person, within the meaning of Section 15 of
the Securities Act, against any and all losses, claims, damages or liabilities,
joint and several, as incurred, to which the Purchaser, or any such person or
entity may become subject, under the Securities Act or otherwise, and will
reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Seller or the omission or the
alleged omission to state therein a material fact necessary in order to make the
statements in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Seller, in the light of the
circumstances under which they were made, not misleading, but only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission relates to the Seller Information contained in the Prospectus
Supplement, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the information on any




                                       18
<PAGE>

computer tape furnished to the Purchaser or an affiliate thereof by or on behalf
of the Seller containing information regarding the assets of the Trust or (iii)
any untrue statement or alleged untrue statement of any material fact contained
in any information provided by the Seller to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to KPMG LLP or prospective investors (directly or
indirectly through available information systems) in connection with the
issuance, marketing or offering of the Certificates. This indemnity agreement
will be in addition to any liability which the Seller may otherwise have.

          (b) The Purchaser agrees to indemnify and hold harmless the Seller,
its officers, directors and each person or entity who controls the Seller, or
any such person, against any and all losses, claims, damages or liabilities,
joint and several, to which the Seller or any such person or entity may become
subject, under the Securities Act or otherwise, and will reimburse the Seller
for any legal or other expenses incurred by the Seller, each officer and
director and controlling person in connection with investigating or defending
any such losses, claims, damages or liabilities insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement or the omission or the alleged omission to state therein a
material fact necessary in order to make the statements in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement, in the
light of the circumstances under which they were made, not misleading, but only
to the extent that such untrue statement or alleged untrue statement or omission
or alleged omission is not contained in the Seller Information in the Prospectus
Supplement. This indemnity agreement will be in addition to any liability which
the Purchaser may otherwise have.

          (c) Promptly after receipt by any indemnified party under this Article
V of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

     If any such claim or action shall be brought against an indemnified party,
and it shall notify the indemnifying party thereof, the indemnifying party shall
be entitled to participate therein and, to the extent that it wishes, jointly
with any other similarly notified indemnifying party, to assume the defense
thereof with counsel reasonably satisfactory to the indemnified party. After
notice from the indemnifying party to the indemnified party of its election to
assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Article V for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     Any indemnified party shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such




                                       19
<PAGE>

indemnified party unless: (i) the employment thereof has been specifically
authorized by the indemnifying party in writing; (ii) such indemnified party
shall have been advised in writing by such counsel that there may be one or more
legal defenses available to it which are different from or additional to those
available to the indemnifying party and in the reasonable judgment of such
counsel it is advisable for such indemnified party to employ separate counsel;
or (iii) the indemnifying party has failed to assume the defense of such action
and employ counsel reasonably satisfactory to the indemnified party, in which
case, if such indemnified party notifies the indemnifying party in writing that
it elects to employ separate counsel at the expense of the indemnifying party,
the indemnifying party shall not have the right to assume the defense of such
action on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser or by the Seller, if the
indemnified parties in this Article V consist of the Seller.

     Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent to a settlement of any action, the indemnifying
party agrees that it shall be liable for any settlement of any proceeding
effected without its written consent if such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid request
and the indemnifying party has not previously provided the indemnified party
with written notice of its objection to such settlement. No indemnifying party
shall effect any settlement of any pending or threatened proceeding in respect
of which an indemnified party is or could have been a party and indemnity is or
could have been sought hereunder, without the written consent of such
indemnified party, unless settlement includes an unconditional release of such
indemnified party from all liability and claims that are the subject matter of
such proceeding.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Article is
for any reason held to be unenforceable although applicable in accordance with
its terms, the Seller, on the one hand, and the Purchaser, on the other, shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by said indemnity agreement incurred by the Seller and
the Purchaser in such proportions as shall be appropriate to reflect the
relative benefits received by the Seller on the one hand and the Purchaser on
the other from the sale of the Mortgage Loans such that the Purchaser is
responsible for the lesser of (i) 0.25% thereof and (ii) 0.25% of the aggregate
proceeds to the Seller from the sale of the Mortgage Loans and the Seller shall
be responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution




                                       20
<PAGE>

from any person who was not guilty of such fraudulent misrepresentation. For
purposes of this Section, each officer and director of the Purchaser and each
person, if any, who controls the Purchaser within the meaning of Section 15 of
the Securities Act shall have the same rights to contribution as the Purchaser
and each director of the Seller, each officer of the Seller, and each person, if
any, who controls the Seller within the meaning of Section 15 of the Securities
Act shall have the same rights to contribution as the Seller.

          (e) The Seller agrees to indemnify and to hold each of the Purchaser,
the Trustee, each of the officers and directors of each such entity and each
person or entity who controls each such entity or person and each
Certificateholder harmless against any and all claims, losses, penalties, fines,
forfeitures, legal fees and related costs, judgments, and any other costs, fees
and expenses that the Purchaser, the Trustee, or any such person or entity and
any Certificateholder may sustain in any way (i) related to the failure of the
Seller to perform its duties in compliance with the terms of this Agreement,
(ii) arising from a breach by the Seller of its representations and warranties
in Section 3.01 or 3.02 of this Agreement or (iii) related to the origination or
prior servicing of the Mortgage Loans by reason of any acts, omissions, or
alleged acts or omissions of the Seller or any servicer. The Seller shall
immediately notify the Purchaser, the Trustee and each Certificateholder if a
claim is made by a third party with respect to this Agreement. The Seller shall
assume 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 Purchaser, the
Trustee or any such person or entity and/or any Certificateholder in respect of
such claim.

                                   ARTICLE VI.

                                   TERMINATION

     Section 6.01 TERMINATION. The respective obligations and responsibilities
of the Seller and the Purchaser created hereby shall terminate, except for the
Seller's indemnity obligations as provided herein upon the termination of the
Trust as provided in Article X of the Pooling and Servicing Agreement.

                                  ARTICLE VII.

                            MISCELLANEOUS PROVISIONS

     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:



                                       21

     if to the Seller:

          Option One Mortgage Corporation
          3 Ada
          Irvine, CA 92618
          Attention: William L. O'Neill

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

     if to the Purchaser:

          Option One Mortgage Acceptance Corporation
          3 Ada
          Irvine, CA 92618
          Attention: William L. O'Neill

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 of 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 of
enforceability of the other provisions of this Agreement.

     Section 7.05 COUNTERPARTS. This Agreement may be executed in one or more
counterparts and 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.



                                       22

     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 pledging the Mortgage Loans 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 PURCHASE AGREEMENT. This
Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Purchaser, the Trustee and the NIMs Insurer, if any. The NIMs
Insurer, if any, shall be a third party beneficiary hereof and may enforce the
terms hereof as if a party hereto. The obligations of the Seller under this
Agreement cannot be assigned or delegated to a third party without the consent
of the Purchaser which consent 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 and the provisions of Article V 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 fist above written.

<PAGE>

enforcement of creditors' rights generally and by general equity principles
(regardless of whether such enforcement is considered in a proceeding in equity
or at law);

          (g) The related Mortgage is a valid and enforceable first or second

Schedule of Mortgage Loans), nor has any instrument been executed that would
effect any such release, cancellation, subordination or rescission;



                                       7
<PAGE>

          (m) No Mortgage Loan is subject to any right of recission, set-off,
counterclaim or defense, including the defense of usury, nor will the operation
of any of the terms of any Mortgage Note or Mortgage, or the exercise of any
right thereunder, render either the Mortgage Note or Mortgage unenforceable in
whole or in part, or subject to any right of recission, set-off, counterclaim or
defense, including the defense of usury, and no such right of recission,
set-off, counterclaim or defense has been asserted with respect thereto;

          (n) To the Originator's knowledge, there is no proceeding pending for
the total or partial condemnation and no eminent domain proceedings pending
affecting any Mortgaged Property;

          (o) Each Mortgage Loan is covered by either (i) a mortgage title
insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged Property is
located, an attorney's opinion of title given by an attorney licensed to
practice law in the jurisdiction where the Mortgaged Property is located. All of
the Originator's rights under such policies, opinions or other instruments shall
be transferred and assigned to Purchaser upon sale and assignment of the
Mortgage Loans hereunder. The title insurance policy has been issued by a title
insurer licensed to do business in the jurisdiction where the Mortgaged Property
is located, insuring the original lender, its successor and assigns, as to the
first or second priority lien of the Mortgage in the original principal amount
of the Mortgage Loan, subject to the exceptions contained in such policy. The
Originator is the sole insured of such mortgagee title insurance policy, and
such mortgagee title insurance policy is in full force and effect and will be in
force and effect upon the consummation of the transactions contemplated by this
Agreement. Neither the Originator nor any affiliate of the Originator has made,
and the Originator has no knowledge of, any claims under such mortgagee title
insurance policy. The Originator is not aware of any action by a prior holder
and neither the Originator nor any affiliate of the Originator has done, by act
or omission, anything which could impair the coverage or enforceability of such
mortgagee title insurance policy or the accuracy of such attorney's opinion of
title;

          (p) There is no material default, breach, violation or event of
acceleration existing under the related Mortgage or the related 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 material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

          (q) With respect to any Mortgage Loan which provides for an adjustable
interest rate, all rate adjustments have been performed in accordance with the
terms of the related Mortgage Note or subsequent modifications, if any;

          (r) To the Originator's knowledge, there are no delinquent taxes,
ground rents, water charges, sewer rents, assessments, insurance premiums,
leasehold payments, including assessments payable in future installments or
other outstanding charges, affecting the related Mortgaged Property;



                                       8
<PAGE>

          (s) No foreclosure proceedings are pending against the Mortgaged
Property and the Mortgage Loan is not subject to any pending bankruptcy or
insolvency proceeding, and to the Originator's best knowledge, no material
litigation or lawsuit relating to the Mortgage Loan is pending;

          (t) The Mortgage Loan obligates the mortgagor thereunder to maintain a
hazard insurance policy ("Hazard Insurance") in an amount at least equal to the
lesser of (i) the maximum insurable value of such improvements or (ii) the
principal balance of the Mortgage Loan with a standard mortgagee clause, in
either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

          (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

          (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
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 (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

          (w) Except as set forth in the appraisal which forms part of the
related Mortgage File, the Mortgaged Property, normal wear and tear excepted, is
undamaged by waste, fire, earthquake or earth movement, windstorm, flood,
tornado or other casualty so as to affect materially and adversely the value




                                       9
<PAGE>

of the Mortgaged Property as security for the Mortgage Loan or the use for which
the premises were intended;

          (x) To the Originator's knowledge, there was no fraud involved in the
origination of the Mortgage Loan by the mortgagee or by the Mortgagor, any
appraiser or any other party involved in the origination of the Mortgage Loan;

          (y) Each Mortgage File contains an appraisal of the 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
performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

          (z) To the best of the Originator's knowledge, all parties which have
had any interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee
or otherwise, are (or, during the period in which they held and disposed of such
interest, were) in compliance with any and all applicable "doing business" and
licensing requirements of the laws of the state wherein the Mortgaged Property
is located;

          (aa) No improvements on the related Mortgaged Property (upon which
value was given) 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 the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

          (bb) Each Mortgage Loan was originated or acquired by a savings and
loan association, a savings bank, a commercial bank or similar banking
institution which is supervised and examined by a federal or state authority, or
by a mortgagee approved by the Secretary of HUD. Each Mortgage Loan was
originated substantially in accordance with the Originator's underwriting
criteria, which are at least as stringent as the underwriting criteria set forth
in the Prospectus Supplement. Each Mortgage Loan is currently being serviced by
the Originator and has been serviced by the Originator since the date of
origination of such Mortgage Loan;

          (cc) (i) Principal payments on the Mortgage Loan commenced no more
than two months after the proceeds of the Mortgage Loan were disbursed and (ii)
each Mortgage Note is payable on the first day of each month;

          (dd) Other than, approximately 0.00% of the Mortgage Loans (by
aggregate principal balance of the Mortgage Loans as of the Cut-off Date), which
are "balloon payment" mortgage loans, each Mortgage Loan is fully amortizing;

          (ee) The Mortgage Loan bears interest at the Mortgage Rate and the
Mortgage Note does not permit negative amortization. No Mortgage Loan bearing
interest at an adjustable rate permits the Mortgagor to convert the Mortgage
Loan to a fixed rate Mortgage Loan;



                                       10
<PAGE>

          (ff) With respect to escrow deposits, if any, all such payments are in
the possession of, or under the control of, the Master Servicer and there exist
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 Master Servicer have been capitalized under
any Mortgage or the related Mortgage Note;

          (gg) No Mortgage Loan contains provisions pursuant to which scheduled
payments are: (i) paid or partially paid with funds deposited in any separate
account established by the Originator, the Seller, the Mortgagor, or anyone on
behalf of the Mortgagor; or (ii) paid by any source other than the Mortgagor or
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;

          (hh) As of the origination date of each Mortgage Loan, the related
Mortgaged Property is lawfully permitted to be occupied under applicable law;

          (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

          (jj) No Mortgage Loan was made in connection with (a) the construction
or rehabilitation of a Mortgaged Property or (b) facilitating the trade-in or
exchange of a Mortgaged Property;

          (kk) 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;

          (ll) There are no mechanics' or similar liens or claims that 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 that are
or may be liens prior to, or equal or coordinate with, the lien of the related
Mortgage;

          (mm) As to each Mortgage Loan, interest is calculated on the Mortgage
Note on the basis of twelve 30-day months and a 360 day year;



                                       11
<PAGE>

          (nn) The Mortgaged Property consists of one of the following: detached
or semi-detached one- to four-family dwelling units, townhouses, individual
condominium units and individual units in planned unit developments, or
manufactured homes;

          (oo) Each Mortgage Loan constitutes a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code;

          (pp) The Mortgage Loans were not intentionally selected by the Seller
in a manner intended to adversely affect the Purchaser or the Trust;

          (qq) The representations, warranties and covenants, set forth in this
Section shall survive the Closing Date;

          (rr) The Mortgage Loans have original terms to maturity ranging from
10 to 30 years;

          (ss) With respect to the Mortgage Loans, no more than 21.26%; 20.20%;
10.30%; 5.47% and 4.85% of the Mortgage Loans, by Cut-off Date Principal Balance
will be secured by Mortgaged Properties located in California, Georgia, New
York, Massachusetts and New Jersey, respectively; and 73.76% of the Mortgage
Loans, by Cut-off Date Principal Balance will be secured by real property with a
single family residence erected thereon and 5.34% of the Mortgage Loans, by the
Cut-off Date Principal Balance are secured by condominiums;

          (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 100%;

          (uu) With respect to each Mortgage Loan, the Mortgage Note related
thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which will be
adjusted on each Adjustment Date to equal the Index plus the Gross Margin,
rounded to the nearest or next highest 0.125%, subject to the Periodic Rate Cap,
the Maximum Mortgage Rate and the Minimum Mortgage Rate;

          (vv) The average Cut-off Date Principal Balance of the Mortgage Loans
is $159,730.35;

          (ww) No Mortgage Loan is subject to the requirements of the Home
Ownership and Equity Protection Act of 1994 ("HOEPA"), nor any state law,
ordinance or regulation similar to HOEPA;

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

          (yy) No Mortgage Loan originated before October 1, 2002 has a
Prepayment Charge term longer than five years after its origination and no
Mortgage Loan originated on or after October 1, 2002 has a Prepayment Charge
term longer than three years after its origination;



                                       12
<PAGE>

          (zz) Each Group I Mortgage Loan had a Principal Balance at origination
which conformed with Fannie Mae/Freddie Mac guidelines.

          (aaa) Each Mortgage Loan conforms, and all Mortgage Loans in the
aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

          (bbb) With respect to second lien Mortgage Loans, either (a) no
consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File;

          (ccc) Each Mortgage Note is comprised of one original promissory note
and each such promissory note constitutes an "instrument" for purposes of
section 9-102(a)(65) of the UCC;

          (ddd) [Reserved];

          (eee) No borrower was encouraged or required to select a Group I
Mortgage Loan product offered by the Originator which is a higher cost product
designed for less creditworthy borrowers, unless at the time of the Group I
Mortgage Loan's origination, such borrower did not qualify taking into account
credit history and debt-to-income ratios for a lower-cost credit product then
offered by the Originator or any affiliate of the Originator. If, at the time of
loan application, the borrower may have qualified for a for a lower-cost credit
product then offered by any mortgage lending affiliate of the Originator, the
Originator referred the borrower's application to such affiliate for
underwriting consideration;

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

          (ggg) With respect to any Group I Mortgage Loan that contains a

the choice of another mortgage product that did not require payment of such a
premium, (iii) the prepayment premium is disclosed to the borrower in the loan
documents pursuant to applicable state and federal law, and (iv) notwithstanding
any state or federal law to the contrary, the Master Servicer shall not impose
such prepayment premium in any instance when the mortgage debt is accelerated as

                                       13

connection with the origination of a Group I Mortgage Loan;

          (iii) All points and fees related to each Group I Mortgage Loan were
disclosed in writing to the borrower in accordance with applicable state and
federal law. Except in the case of a Group I Mortgage Loan in an original
principal amount of less than $60,000 which would have resulted in an

anti-predatory lending eligibility for purchase requirements of the Fannie Mae
Lender Letter, LL03-00: Eligibility of Mortgages to Borrowers with Blemished
Credit Records (04/11/00) other than the requirements regarding Escrow Deposit

Property is located to the extent necessary to ensure the enforceability of each
Mortgage Loan in accordance with the terms of this Agreement;

authorization, execution and delivery by the Purchaser and the Originator,
constitutes a legal, valid and binding obligation of the Seller, enforceable
against it in accordance with its terms except as the enforceability thereof may
be limited by bankruptcy, insolvency or reorganization;

          (c) The execution and delivery of this Agreement by the Seller and the
performance of and compliance with the terms of this Agreement will not violate
the Seller's certificate of trust or constitute a default under or result in a
breach or acceleration of, any material contract, agreement or other instrument
to which the Seller is a party or which may be applicable to the Seller or its
assets;

          (d) The Seller is not in violation of, and the execution and delivery
of this Agreement by the Seller 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 over the Seller or its
assets, which violation might have consequences that would materially and
adversely affect the condition (financial or otherwise) or the operation of the

adversely affect the performance of its obligations and duties hereunder; and

          (e) Immediately prior to the payment of the Purchase Price for each
Mortgage Loan, the Seller was the owner of the related Mortgage and the
indebtedness evidenced by the related Mortgage Note and upon the payment of the
Purchase Price by the Purchaser, in the event that the Seller retains




                                       18

with any intent to hinder, delay or defraud any of its creditors;

          (g) There are no actions or proceedings against, or investigations
known to it of, the Seller before any court, administrative or other tribunal
(A) that might prohibit its entering into this Agreement, (B) seeking to prevent

validity or enforceability of, this Agreement;

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

          (i) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Seller, and the transfer
assignment and conveyance of the Mortgage Notes and the Mortgages by the Seller
pursuant to this Agreement are not subject to the bulk transfer or any similar
statutory provisions; and

          (j) Except with respect to liens released immediately prior to the
transfer herein contemplated, each Mortgage Note and related Mortgage have not
been assigned or pledged and immediately prior to the transfer and assignment
herein contemplated, the Seller held good, marketable and indefeasible title to,
and was the sole owner and holder of, each Mortgage Loan subject to no liens,
charges, mortgages, claims, participation interests, equities, pledges or
security interests of any nature, encumbrances or rights of others
(collectively, a "Lien"); the Seller has full right and authority under all
governmental and regulatory bodies having jurisdiction over the Seller, subject
to no interest or participation of, or agreement with, any party, to sell and
assign the same pursuant to this Agreement; and immediately upon the transfers
and assignments herein contemplated, the Seller shall have transferred all of
its right, title and interest in and to each Mortgage Loan and the Trustee will
hold good, marketable and indefeasible title to, and be the sole owner of, each
Mortgage Loan subject to no Liens.

     Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It is
understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Originator or as to which the Originator has no
knowledge, if it is discovered that the substance of any such representation and
warranty is inaccurate and the inaccuracy materially and adversely affects the
value of the related Mortgage Loan, or the interest therein of the Purchaser or
the Purchaser's assignee, designee or transferee, then notwithstanding the




                                       19
<PAGE>

Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by either the Originator, the Master Servicer or the
Purchaser of a breach of any of the foregoing representations and warranties
that materially and adversely affects the value of the Mortgage Loans or the
interest of the Purchaser (or which materially and adversely affects the
interests of the Purchaser in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the others. It is
understood by the parties hereto that a breach of the representations and
warranties made in Section 3.01(ww), (xx) and (jjj) will be deemed to materially
and adversely affect the value of the related Mortgage Loan or the interest of
the Purchaser.

     Within 120 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Purchase Price. In the event that a breach
shall involve any representation or warranty set forth in Section 3.02 or 3.03
and such breach cannot be cured within 120 days of the earlier of either
discovery by or notice to the Originator of such breach, each Mortgage Loan
shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price, as such term is defined in the Pooling and Servicing Agreement.
The Originator may, at the request of the Purchaser and assuming the Originator
has a Qualified Substitute Mortgage Loan, rather than repurchase a deficient
Mortgage Loan as provided above, remove such Mortgage Loan and substitute in its
place a Qualified Substitute Mortgage Loan or Loans. If the Originator does not
provide a Qualified Substitute Mortgage Loan or Loans, it shall repurchase the
deficient Mortgage Loan. Any repurchase of a Mortgage Loan(s) pursuant to the
foregoing provisions of this Section 3.04 shall occur on a date designated by
the Purchaser and shall be accomplished by deposit in accordance with Section
2.03 of the Pooling and Servicing Agreement. Any repurchase or substitution
required by this Section shall be made in a manner consistent with Section 2.03
of the Pooling and Servicing Agreement.

     At the time of substitution or repurchase of any deficient Mortgage Loan,
the Purchaser and the Originator shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Originator and the delivery to
the Originator of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Originator shall, simultaneously with such deposit, give
written notice to the Purchaser that such deposit has taken place. Upon such
repurchase, the Mortgage Loan Schedule shall be amended to reflect the
withdrawal of the repurchased Mortgage Loan from this Agreement.

     As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing




                                       20
<PAGE>

Agreement, with the Mortgage Note endorsed as required therein. The Originator
shall deposit in the Collection Account the Monthly Payment less the Servicing
Fee due on such Qualified Substitute Mortgage Loan or Loans in the month
following the date of such substitution. Monthly Payments due with respect to
Qualified Substitute Mortgage Loans in the month of substitution will be
retained by the Originator. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Originator shall thereafter be entitled to
retain all amounts subsequently received by the Originator in respect of such
Deleted Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage
Loans shall be subject to the terms of this Agreement in all respects, and the
Originator shall be deemed to have made with respect to such Qualified
Substitute Mortgage Loan or Loans as of the date of substitution, the covenants,
representations and warranties set forth in Sections 3.01, 3.02 and 3.03.

     It is understood and agreed that the representations and warranties set
forth in Section 3.01 shall survive delivery of the respective Mortgage Files to
the Trustee on behalf of the Purchaser.

     It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS


     Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby covenants
that except for the transfer hereunder, neither the Originator nor the Seller
will 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 Originator 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 Originator will defend the right, title and interest of the
Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or 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 Originator or 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.


                                   ARTICLE V.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS




                                       21
<PAGE>

     Section 5.01 INDEMNIFICATION.

          (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator or the omission or
the alleged omission to state therein a material fact necessary in order to make
the statements in the Prospectus Supplement or any amendment or supplement to
the Prospectus Supplement approved in writing by the Originator, in the light of
the circumstances under which they were made, not misleading, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission relates to the Originator Information contained in the
Prospectus Supplement, (ii) any untrue statement or alleged untrue statement of
any material fact contained in the information on any computer tape furnished to
the Purchaser or an affiliate thereof by or on behalf of the Originator
containing information regarding the assets of the Trust or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
information provided by the Originator to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to KPMG LLP or prospective investors (directly or
indirectly through available information systems) in connection with the
issuance, marketing or offering of the Certificates. This indemnity agreement
will be in addition to any liability which the Originator may otherwise have.

          (b) The Purchaser agrees to indemnify and hold harmless the Seller and
the Originator, each of their respective officers, directors and each person or
entity who controls the Seller, the Originator or any such person, against any
and all losses, claims, damages or liabilities, joint and several, to which the
Seller, the Originator or any such person or entity may become subject, under
the Securities Act or otherwise, and will reimburse the Seller and/or the
Originator for any legal or other expenses incurred by the Seller, the
Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.



                                       22
<PAGE>

          (c) Promptly after receipt by any indemnified party under this Article
V of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

     If any such claim or action shall be brought against an indemnified party,
and it shall notify the indemnifying party thereof, the indemnifying party shall
be entitled to participate therein and, to the extent that it wishes, jointly
with any other similarly notified indemnifying party, to assume the defense
thereof with counsel reasonably satisfactory to the indemnified party. After
notice from the indemnifying party to the indemnified party of its election to
assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Article V for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     Any indemnified party shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

     Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement




                                       23
<PAGE>

or judgment. Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to consent to a
settlement of any action, the indemnifying party agrees that it shall be liable
for any settlement of any proceeding effected without its written consent if
such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and the indemnifying party has not
previously provided the indemnified party with written notice of its objection
to such settlement. No indemnifying party shall effect any settlement of any
pending or threatened proceeding in respect of which an indemnified party is or
could have been a party and indemnity is or could have been sought hereunder,
without the written consent of such indemnified party, unless settlement
includes an unconditional release of such indemnified party from all liability
and claims that are the subject matter of such proceeding.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Article is
for any reason held to be unenforceable although applicable in accordance with
its terms, the Seller and the Originator, on the one hand, and the Purchaser, on
the other, shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement
incurred by the Seller, the Originator and the Purchaser in such proportions as
shall be appropriate to reflect the relative benefits received by the Seller and
the Originator on the one hand and the Purchaser on the other from the sale of
the Mortgage Loans such that the Purchaser is responsible for the lesser of (i)
0.25% thereof and (ii) 0.25% of the aggregate proceeds to the Seller from the
sale of the Mortgage Loans and the Originator shall be responsible for the
balance; PROVIDED, HOWEVER, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section, each officer and
director of the Purchaser and each person, if any, who controls the Purchaser
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Purchaser, each director of the Originator, each
officer of the Originator, and each person, if any, who controls the Originator
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Originator and each director of the Seller, each
officer of the Seller, and each person, if any, who controls the Seller within
the meaning of Section 15 of the Securities Act shall have the same rights to
contribution as the Seller.

          (e) The Originator agrees to indemnify and to hold each of the
Purchaser, the Trustee, each of the officers and directors of each such entity
and each person or entity who controls each such entity or person and each
Certificateholder harmless against any and all claims, losses, penalties, fines,
forfeitures, legal fees and related costs, judgments, and any other costs, fees
and expenses that the Purchaser, the Trustee, or any such person or entity and
any Certificateholder may sustain in any way (i) related to the failure of the
Originator to perform its duties in compliance with the terms of this Agreement,
(ii) arising from a breach by the Originator of its representations and
warranties in Section 3.01, 3.02 or 3.03 of this Agreement or (iii) related to
the origination or prior servicing of the Mortgage Loans by reason of any acts,
omissions, or alleged acts or omissions of the Originator, the Seller or any
servicer. The Originator shall immediately notify the Purchaser, the Trustee and
each Certificateholder if a claim is made by a third party with respect to this
Agreement. The Originator shall assume the defense of any such claim and pay all
expenses in connection therewith, including reasonable counsel fees, and
promptly pay,




                                       24
<PAGE>

discharge and satisfy any judgment or decree which may be entered against the
Purchaser, the Trustee or any such person or entity and/or any Certificateholder
in respect of such claim.

                                   ARTICLE VI.

                                   TERMINATION


     Section 6.01 TERMINATION. The respective obligations and responsibilities
of the Originator, the Seller and the Purchaser created hereby shall terminate,
except for the Originator's indemnity obligations as provided herein upon the
termination of the Trust as provided in Article X of the Pooling and Servicing
Agreement.

                                  ARTICLE VII.

          Wilmington, Delaware 19890
          Attention: Corporate Trust Administration

     Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the

enforceability of the other provisions of this Agreement.

     Section 7.05 COUNTERPARTS. This Agreement may be executed in one or more
counterparts and 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, the Seller and the
Originator 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 Originator
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
Originator 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,




                                       26
<PAGE>

covenants, opinions of counsel, letters from auditors, and certificates of
public officials or officers of the Originator 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 pledging the Mortgage Loans 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 PURCHASE AGREEMENT. This
Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Originator, the Purchaser, the Trustee and the NIMs Insurer, if any.
The NIMs Insurer, if any, shall be a third party beneficiary hereof and may
enforce the terms hereof as if a party hereto. The obligations of the Seller and
the Originator under this Agreement cannot be assigned or delegated to a third
party without the consent of the Purchaser which consent shall be at the
Purchaser's sole discretion, except that the Purchaser acknowledges and agrees
that the Seller or the Originator may assign its obligations hereunder to any
Person into which the Seller or the Originator is merged or any corporation
resulting from any merger, conversion or consolidation to which the Seller or
the Originator is a party or any Person succeeding to the business of the Seller
or the Originator. The parties hereto acknowledge that the Purchaser is
acquiring the Mortgage Loans for the purpose of contributing them to a trust

recording and (2) if such copy is certified by the Originator, 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. If the original lender's title

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 deliver such missing document to the Purchaser.
If the Seller does not cure such defect or deliver such missing document within
such time period, the Originator shall either repurchase or substitute for such
Mortgage Loan pursuant to Section 2.03 of the Pooling and Servicing Agreement.

     The Purchaser hereby acknowledges its acceptance of all right, title and
interest to the Mortgage Loans and other property, now existing and hereafter
created, conveyed to it pursuant to Section 2.01.

     The parties hereto intend that the transaction set forth herein be a sale
by the Seller to the Purchaser of all the Seller's right, title and interest in
and to the Mortgage Loans and other property described above. In the event the
transaction set forth herein is deemed not to be a sale, the Seller hereby
grants to the Purchaser a security interest in all of the Seller's right, title
and interest in, to and under the Mortgage Loans and other property described
above, whether now existing or hereafter created, to secure all of the Seller's
obligations hereunder; and this Agreement shall constitute a security agreement
under applicable law.

     The Originator shall cause the Assignments which were delivered in blank to
be completed and shall cause all Assignments referred to in Section 2.02(iii)
hereof and, to the extent necessary, in Section 2.02(iv) hereof to be recorded.
The Originator shall be required to deliver such Assignments for recording
within 90 days of the Closing Date. Notwithstanding the foregoing, however, for
administrative convenience and facilitation of servicing and to reduce closing
costs, the Assignments of Mortgage shall not be required to be submitted for
recording with respect to any Mortgage Loan in any jurisdiction where the Rating
Agencies do not require recordation in order to receive the ratings on the
Certificates at the time of their initial issuance; PROVIDED, HOWEVER, each
Assignment shall be submitted for recording by the Originator in the manner
described above, at no expense to the Trust Fund or Trustee, upon the earliest
to occur of:




                                       4

(i) reasonable direction by Holders of Certificates entitled to at least 25% of
the Voting Rights, or the NIMS Insurer, (ii) the occurrence of a Master Servicer
Event of Termination, (iii) the occurrence of a bankruptcy, insolvency or
foreclosure relating to the Master Servicer, (iv) the occurrence of a servicing
transfer as described in Section 7.02 hereof, (v) if the Originator is not the
Master Servicer and with respect to any one Assignment the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Mortgagor under the
related Mortgage and (vi) any Mortgage Loan that is 90 days or more Delinquent.
Upon (a) receipt of written notice from the Trustee that recording of the
Assignments is required pursuant to one or more of the conditions (excluding (v)
and (vi) above) set forth in the preceding sentence or (b) upon the occurrence
of condition (v) or (vi) in the preceding sentence, the Originator shall be
required to deliver such Assignments for recording as provided above, promptly
and in any event within 30 days following receipt of such notice.
Notwithstanding the foregoing, if the Originator fails to pay the cost of
recording the Assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust. The Originator shall
furnish the Trustee, or its designated agent, with a copy of each Assignment
submitted for recording. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Originator 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. In the event
that any Mortgage Note is endorsed in blank as of the Closing Date, within
ninety (90) days of the Closing Date the Originator shall cause to be completed
such endorsements "Pay to the order of Wells Fargo Bank Minnesota, National
Association, as Trustee, without recourse."

     The Originator shall forward to the Purchaser original documents evidencing
an assumption, modification, consolidation or extension of any Mortgage Loan
entered into in accordance with the Pooling and Servicing Agreement within two
weeks of their execution; PROVIDED, HOWEVER, that the Originator shall provide
the Purchaser with a certified true copy of any such document submitted for
recordation within two weeks of its execution, and shall provide the original of
any document submitted for recordation or a copy of such document certified by
the appropriate public recording office to be a true and complete copy of the
original within 365 days of its submission for recordation. In the event that
the Originator cannot provide a copy of such document certified by the public
recording office within such 365 day period, the Originator shall deliver to the
Purchaser, within such 365 day period, an Officer's Certificate of the Master
Servicer which shall (A) identify the recorded document, (B) state that the
recorded document has not been delivered to the Purchaser due solely to a delay
caused by the public recording office, (C) state the amount of time generally
required by the applicable recording office to record and return a document
submitted for recordation, if known, and (D) specify the date the applicable
recorded document is expected to be delivered to the Purchaser, and, upon
receipt of a copy of such document certified by the public recording office, the
Originator shall immediately deliver such document to the Purchaser. In the
event the appropriate public recording office will not certify as to the
accuracy of such document, the Originator shall deliver a copy of such document

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH


     Section 3.01 ORIGINATOR REPRESENTATIONS AND WARRANTIES RELATING TO THE

the Mortgage Loan;

          (b) Immediately prior to the transfer and assignment to the Purchaser,
the Mortgage Note and the Mortgage Loan were not subject to an assignment or
pledge, and the Seller has full right and authority to sell and assign the
Mortgage Loan;

          (c) The Seller is transferring such Mortgage Loan to the Purchaser
free and clear of any and all liens, pledges, charges or security interests of
any nature encumbering the Mortgage Loans;

material respects as of the Cut-off Date or such other date as may be indicated
in such schedule;

          (e) The Mortgage Loan has been acquired, serviced, collected and
otherwise dealt with by the Originator and any affiliate of the Originator in
compliance with all applicable federal, state and local laws and regulations,
including, but not limited to, all applicable predatory and abusive lending laws
and the terms of the related Mortgage Note and Mortgage;

          (f) The related Mortgage Note and Mortgage are genuine and each is the
legal, valid and binding obligation of the maker thereof, enforceable in
accordance with its terms except as such enforcement may be limited by
bankruptcy, insolvency, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and by general equity principles
(regardless of whether such enforcement is considered in a proceeding in equity
or at law);



                                       6
<PAGE>

          (g) The related Mortgage is a valid and enforceable first or second
lien on the related Mortgaged Property, which Mortgaged Property is free and
clear of all encumbrances and liens (including mechanics liens) having priority
over the first or second lien of the Mortgage except for: (i) liens for real
estate taxes and assessments not yet due and payable; (ii) covenants, conditions
and restrictions, rights of way, easements and other matters of public record as
of the date of recording of such Mortgage, such exceptions appearing of record
being acceptable to mortgage lending institutions generally or specifically
reflected or considered in the lender's title insurance policy delivered to the
originator of the Mortgage Loan and referred to in the appraisal made in
connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

          (h) Any security agreement, chattel mortgage or equivalent document
related to such Mortgage Loan establishes and creates a valid and enforceable
first or second lien on the Mortgaged Property;

          (i) As of the last calendar day of May 2003 and with respect to any
Mortgage Loan that had a payment due on or before May 1, 2003, except with
respect to 1.98% of the Mortgage Loans by the aggregate Cut-off Date Principal
Balance of the Mortgage Loans, the related Monthly Payment due on May 1, 2003
has been received. In addition, 0.00% of the Mortgage Loans have been 30 or more
days delinquent in the last 12 months and 0.00% of the Mortgage Loans have been
30 or more days delinquent for two payment periods in the last 12 months;

          (j) Neither the Originator nor the Seller has advanced funds, or
induced, solicited or knowingly received any advance of funds by a party other
than the Mortgagor, directly or indirectly, for the payment of any amount
required under the Mortgage Loan;

          (k) Neither the Originator nor the Seller has impaired, waived,
altered or modified the related Mortgage or Mortgage Note in any material
respect, or satisfied, canceled, rescinded or subordinated such Mortgage or
Mortgage Note in whole or in part or released all or any material portion of the
Mortgaged Property from the lien of the Mortgage, or executed any instrument of
release, cancellation, rescission or satisfaction of the Mortgage Note or
Mortgage;

          (l) As of the Cut-off Date, the Mortgage has not been satisfied,
canceled or subordinated, in whole or in part, or rescinded, and the Mortgaged
Property has not been released from the lien of the Mortgage, in whole or in
part (except for a release that does not materially impair the security of the
Mortgage Loan or a release the effect of which is reflected in the Loan-to-Value
Ratio or combined Loan-to-Value Ratio for the Mortgage Loan as set forth in the
Schedule of Mortgage Loans), nor has any instrument been executed that would
effect any such release, cancellation, subordination or rescission;

          (m) No Mortgage Loan is subject to any right of recission, set-off,
counterclaim or defense, including the defense of usury, nor will the operation
of any of the terms of any Mortgage Note or Mortgage, or the exercise of any
right thereunder, render either the Mortgage Note or Mortgage unenforceable in
whole or in part, or subject to any right of recission, set-off, counterclaim or
defense,




                                       7
<PAGE>

including the defense of usury, and no such right of recission, set-off,
counterclaim or defense has been asserted with respect thereto;

          (n) To the Originator's knowledge, there is no proceeding pending for
the total or partial condemnation and no eminent domain proceedings pending
affecting any Mortgaged Property;

          (o) Each Mortgage Loan is covered by either (i) a mortgage title
insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged Property is
located, an attorney's opinion of title given by an attorney licensed to
practice law in the jurisdiction where the Mortgaged Property is located. All of
the Originator's rights under such policies, opinions or other instruments shall
be transferred and assigned to Purchaser upon sale and assignment of the
Mortgage Loans hereunder. The title insurance policy has been issued by a title
insurer licensed to do business in the jurisdiction where the Mortgaged Property
is located, insuring the original lender, its successor and assigns, as to the
first or second priority lien of the Mortgage in the original principal amount
of the Mortgage Loan, subject to the exceptions contained in such policy. The
Originator is the sole insured of such mortgagee title insurance policy, and
such mortgagee title insurance policy is in full force and effect and will be in
force and effect upon the consummation of the transactions contemplated by this
Agreement. Neither the Originator nor any affiliate of the Originator has made,
and the Originator has no knowledge of, any claims under such mortgagee title
insurance policy. The Originator is not aware of any action by a prior holder
and neither the Originator nor any affiliate of the Originator has done, by act
or omission, anything which could impair the coverage or enforceability of such
mortgagee title insurance policy or the accuracy of such attorney's opinion of
title;

          (p) There is no material default, breach, violation or event of
acceleration existing under the related Mortgage or the related 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 material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

          (q) With respect to any Mortgage Loan which provides for an adjustable
interest rate, all rate adjustments have been performed in accordance with the
terms of the related Mortgage Note or subsequent modifications, if any;

          (r) To the Originator's knowledge, there are no delinquent taxes,
ground rents, water charges, sewer rents, assessments, insurance premiums,
leasehold payments, including assessments payable in future installments or
other outstanding charges, affecting the related Mortgaged Property;

          (s) No foreclosure proceedings are pending against the Mortgaged
Property and the Mortgage Loan is not subject to any pending bankruptcy or
insolvency proceeding, and to the Originator's best knowledge, no material
litigation or lawsuit relating to the Mortgage Loan is pending;



                                       8
<PAGE>

          (t) The Mortgage Loan obligates the mortgagor thereunder to maintain a
hazard insurance policy ("Hazard Insurance") in an amount at least equal to the
lesser of (i) the maximum insurable value of such improvements or (ii) the
principal balance of the Mortgage Loan with a standard mortgagee clause, in
either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

          (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

          (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
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 (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

          (w) Except as set forth in the appraisal which forms part of the
related Mortgage File, the Mortgaged Property, normal wear and tear excepted, is
undamaged by waste, fire, earthquake or earth movement, windstorm, flood,
tornado or other casualty so as to affect materially and adversely the value of
the Mortgaged Property as security for the Mortgage Loan or the use for which
the premises were intended;

          (x) To the Originator's knowledge, there was no fraud involved in the
origination of the Mortgage Loan by the mortgagee or by the Mortgagor, any
appraiser or any other party involved in the origination of the Mortgage Loan;





                                       9
<PAGE>

          (y) Each Mortgage File contains an appraisal of the 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
performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

          (z) To the best of the Originator's knowledge, all parties which have
had any interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee
or otherwise, are (or, during the period in which they held and disposed of such
interest, were) in compliance with any and all applicable "doing business" and
licensing requirements of the laws of the state wherein the Mortgaged Property
is located;

          (aa) No improvements on the related Mortgaged Property (upon which
value was given) 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 the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

          (bb) Each Mortgage Loan was originated or acquired by a savings and
loan association, a savings bank, a commercial bank or similar banking
institution which is supervised and examined by a federal or state authority, or
by a mortgagee approved by the Secretary of HUD. Each Mortgage Loan was
originated substantially in accordance with the Originator's underwriting
criteria, which are at least as stringent as the underwriting criteria set forth
in the Prospectus Supplement. Each Mortgage Loan is currently being serviced by
the Originator and has been serviced by the Originator since the date of
origination of such Mortgage Loan;

          (cc) (i) Principal payments on the Mortgage Loan commenced no more
than two months after the proceeds of the Mortgage Loan were disbursed and (ii)
each Mortgage Note is payable on the first day of each month;

          (dd) Other than approximately 0.03% of the Mortgage Loans (by
aggregate principal balance of the Mortgage Loans as of the Cut-off Date), which
are "balloon payment" mortgage loans, each Mortgage Loan is fully amortizing;

          (ee) The Mortgage Loan bears interest at the Mortgage Rate and the
Mortgage Note does not permit negative amortization. No Mortgage Loan bearing
interest at an adjustable rate permits the Mortgagor to convert the Mortgage
Loan to a fixed rate Mortgage Loan;

          (ff) With respect to escrow deposits, if any, all such payments are in
the possession of, or under the control of, the Master Servicer and there exist
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 Master Servicer have been capitalized under
any Mortgage or the related Mortgage Note;

          (gg) No Mortgage Loan contains provisions pursuant to which scheduled
payments are: (i) paid or partially paid with funds deposited in any separate
account established by the Originator, the





                                       10
<PAGE>

Seller, the Mortgagor, or anyone on behalf of the Mortgagor; or (ii) paid by any
source other than the Mortgagor or 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;

          (hh) As of the origination date of each Mortgage Loan, the related
Mortgaged Property is lawfully permitted to be occupied under applicable law;

          (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

          (jj) No Mortgage Loan was made in connection with (a) the construction
or rehabilitation of a Mortgaged Property or (b) facilitating the trade-in or
exchange of a Mortgaged Property;

          (kk) 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;

          (ll) There are no mechanics' or similar liens or claims that 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 that are
or may be liens prior to, or equal or coordinate with, the lien of the related
Mortgage;

          (mm) As to each Mortgage Loan, interest is calculated on the Mortgage
Note on the basis of twelve 30-day months and a 360 day year;

          (nn) The Mortgaged Property consists of one of the following: detached
or semi-detached one- to four-family dwelling units, townhouses, individual
condominium units and individual units in planned unit developments, or
manufactured homes;

          (oo) Each Mortgage Loan constitutes a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code;

          (pp) The Mortgage Loans were not intentionally selected by the Seller
in a manner intended to adversely affect the Purchaser or the Trust;



                                       11
<PAGE>

          (qq) The representations, warranties and covenants, set forth in this
Section shall survive the Closing Date;

          (rr) The Mortgage Loans have original terms to maturity ranging from
10 to 30 years;

          (ss) With respect to the Mortgage Loans, no more than 19.24%; 15.48%;
8.14%; 6.67% and 6.20% of the Mortgage Loans, by Cut-off Date Principal Balance
will be secured by Mortgaged Properties located in California, New York, Texas,
Massachusetts and Florida, respectively; and 75.15% of the Mortgage Loans, by
Cut-off Date Principal Balance will be secured by real property with a single
family residence erected thereon and 3.64% of the Mortgage Loans, by the Cut-off
Date Principal Balance are secured by condominiums;

          (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 95.00%;

          (uu) With respect to each Mortgage Loan, the Mortgage Note related
thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which will be
adjusted on each Adjustment Date to equal the Index plus the Gross Margin,
rounded to the nearest or next highest 0.125%, subject to the Periodic Rate Cap,
the Maximum Mortgage Rate and the Minimum Mortgage Rate;

          (vv) The average Cut-off Date Principal Balance of the Mortgage Loans
is $159,816.74;

          (ww) No Mortgage Loan is subject to the requirements of the Home
Ownership and Equity Protection Act of 1994 ("HOEPA"), nor any state law,
ordinance or regulation similar to HOEPA;

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

          (yy) No Mortgage Loan originated before October 1, 2002 has a
Prepayment Charge term longer than five years after its origination and no
Mortgage Loan originated on or after October 1, 2002 has a Prepayment Charge
term longer than three years after its origination;

          (zz) Each Group I Mortgage Loan had a Principal Balance at origination
which conformed with Fannie Mae/Freddie Mac guidelines.

          (aaa) Each Mortgage Loan conforms, and all Mortgage Loans in the
aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

          (bbb) With respect to second lien Mortgage Loans, either (a) no
consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File;



                                       12
<PAGE>

          (ccc) Each Mortgage Note is comprised of one original promissory note
and each such promissory note constitutes an "instrument" for purposes of
section 9-102(a)(65) of the UCC;

          (ddd) [Reserved];

          (eee) No borrower was encouraged or required to select a Mortgage Loan
product offered by the Originator which is a higher cost product designed for
less creditworthy borrowers, unless at the time of the Mortgage Loan's
origination, such borrower did not qualify taking into account credit history
and debt-to-income ratios for a lower-cost credit product then offered by the
Originator or any affiliate of the Originator. If, at the time of loan
application, the borrower may have qualified for a for a lower-cost credit
product then offered by any mortgage lending affiliate of the Originator, the
Originator referred the borrower's application to such affiliate for
underwriting consideration;

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

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

          (hhh) No borrower of a Group I Mortgage Loan was required to purchase
any credit life, disability, accident or health insurance product as a condition
of obtaining the extension of credit. No borrower obtained a prepaid
single-premium credit life, disability, accident or health insurance policy in
connection with the origination of a Group I Mortgage Loan;

          (iii) All points and fees related to each Group I Mortgage Loan were
disclosed in writing to the borrower in accordance with applicable state and
federal law. Except in the case of a Group I Mortgage Loan in an original
principal amount of less than $60,000 which would have resulted in an
unprofitable origination, no borrower was charged "points and fees" (whether or
not financed) in an amount greater than 5% of the principal amount of such loan,
such 5% limitation calculated in accordance with the Lender Letter. All fees and
charges (including finance charges) and whether or not financed, assessed,
collected or to be collected in connection with the origination and servicing of
each Group I Mortgage Loan




                                       13
<PAGE>

has been disclosed in writing to the borrower in accordance with applicable
state and federal law and regulation;

          (jjj) None of the Mortgage Loans originated in Georgia are subject to

located in the State of Georgia was originated (or modified) on or after October
1, 2002 through and including March 6, 2003;

          (lll) Each Group I Mortgage Loan is in compliance with the
anti-predatory lending eligibility for purchase requirements of the Fannie Mae
Lender Letter, LL03-00: Eligibility of Mortgages to Borrowers with Blemished
Credit Records (04/11/00) other than the requirements regarding Escrow Deposit
Accounts;

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

          (nnn) None of the Mortgage Loans are High Cost as defined by the

obligations under, or validity of enforceability of, this Agreement;

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

               (ix) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Originator. The sale of
the Mortgage Loans was in the ordinary course of business of the Originator and
the assignment and conveyance of the Mortgage Notes and the Mortgages by the
Originator are not subject to the bulk transfer or any similar statutory
provisions;

               (x) The information delivered by the Originator to the Purchaser
with respect to the Originator's loan loss, foreclosure and delinquency
experience on mortgage loans underwritten to similar standards as the Mortgage
Loans and covering mortgaged properties similar to the Mortgaged Properties, is
true and correct in all material respects as of the date of such report;

               (xi) Except with respect to any statement regarding the
intentions of the Purchaser, or any other statement contained herein the truth
or falsity of which is dependant solely upon the actions of the Purchaser, this
Agreement does not contain any untrue statement of material fact or omit to
state a material fact necessary to make the statements contained herein not
misleading. The written




                                       15
<PAGE>

statements, reports and other documents prepared and furnished or to be prepared
and furnished by the Originator pursuant to this Agreement or in connection with
the transactions contemplated hereby taken in the aggregate do not contain any
untrue statement of material fact or omit to state a material fact necessary to
make the statements contained therein not misleading; and

               (xii) The Originator has not transferred the Mortgage Loans with
any intent to hinder, delay or defraud any of its creditors.

     Section 3.03 ORIGINATOR REPRESENTATIONS AND WARRANTIES RELATING TO THE
SELLER. The Originator represents, warrants and covenants to the Purchaser as of
the Closing Date or as of such other date specifically provided herein:

          (a) The Seller is duly organized, validly existing and in good
standing as a business trust under the laws of the State of Delaware and is and
will remain in compliance with the laws of each state in which any Mortgaged
Property is located to the extent necessary to ensure the enforceability of each
Mortgage Loan in accordance with the terms of this Agreement;

          (b) The Seller has the full power and authority to hold each Mortgage
Loan, to sell each Mortgage Loan, to execute, deliver and perform, and to enter
into and consummate, all transactions contemplated by this Agreement. The Seller
has duly authorized the execution, delivery and performance of this Agreement,
has duly executed and delivered this Agreement and this Agreement, assuming due
authorization, execution and delivery by the Purchaser and the Originator,
constitutes a legal, valid and binding obligation of the Seller, enforceable
against it in accordance with its terms except as the enforceability thereof may
be limited by bankruptcy, insolvency or reorganization;

          (c) The execution and delivery of this Agreement by the Seller and the
performance of and compliance with the terms of this Agreement will not violate
the Seller's certificate of trust or constitute a default under or result in a
breach or acceleration of, any material contract, agreement or other instrument
to which the Seller is a party or which may be applicable to the Seller or its
assets;

          (d) The Seller is not in violation of, and the execution and delivery
of this Agreement by the Seller 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 over the Seller or its
assets, which violation might have consequences that would materially and
adversely affect the condition (financial or otherwise) or the operation of the
Seller or its assets or might have consequences that would materially and
adversely affect the performance of its obligations and duties hereunder; and

          (e) Immediately prior to the payment of the Purchase Price for each
Mortgage Loan, the Seller was the owner of the related Mortgage and the
indebtedness evidenced by the related Mortgage Note and upon the payment of the
Purchase Price by the Purchaser, in the event that the Seller retains record
title, the Seller shall retain such record title to each Mortgage, each related
Mortgage Note and the related Mortgage Files with respect thereto in trust for
the Purchaser as the owner thereof;



                                       16

          (f) The Seller has not transferred the Mortgage Loans to the Purchaser
with any intent to hinder, delay or defraud any of its creditors;

          (g) There are no actions or proceedings against, or investigations
known to it of, the Seller before any court, administrative or other tribunal
(A) that might prohibit its entering into this Agreement, (B) seeking to prevent
the sale of the Mortgage Loans or the consummation of the transactions
contemplated by this Agreement or (C) that might prohibit or materially and
adversely affect the performance by the Seller of its obligations under, or
validity or enforceability of, this Agreement;

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

          (i) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Seller, and the transfer
assignment and conveyance of the Mortgage Notes and the Mortgages by the Seller
pursuant to this Agreement are not subject to the bulk transfer or any similar
statutory provisions; and

          (j) Except with respect to liens released immediately prior to the
transfer herein contemplated, each Mortgage Note and related Mortgage have not
been assigned or pledged and immediately prior to the transfer and assignment
herein contemplated, the Seller held good, marketable and indefeasible title to,
and was the sole owner and holder of, each Mortgage Loan subject to no liens,
charges, mortgages, claims, participation interests, equities, pledges or
security interests of any nature, encumbrances or rights of others
(collectively, a "Lien"); the Seller has full right and authority under all
governmental and regulatory bodies having jurisdiction over the Seller, subject
to no interest or participation of, or agreement with, any party, to sell and
assign the same pursuant to this Agreement; and immediately upon the transfers
and assignments herein contemplated, the Seller shall have transferred all of
its right, title and interest in and to each Mortgage Loan and the Trustee will
hold good, marketable and indefeasible title to, and be the sole owner of, each
Mortgage Loan subject to no Liens.

     Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It is
understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Originator or as to which the Originator has no
knowledge, if it is discovered that the substance of any such representation and
warranty is inaccurate and the inaccuracy materially and adversely affects the
value of the related Mortgage Loan, or the interest therein of the Purchaser or
the Purchaser's assignee, designee or transferee, then notwithstanding the
Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by




                                       17
<PAGE>

either the Originator, the Master Servicer or the Purchaser of a breach of any
of the foregoing representations and warranties that materially and adversely
affects the value of the Mortgage Loans or the interest of the Purchaser (or
which materially and adversely affects the interests of the Purchaser in the
related Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others. It is understood by the parties hereto that a
breach of the representations and warranties made in Section 3.01(ww), (xx) and
(jjj) will be deemed to materially and adversely affect the value of the related
Mortgage Loan or the interest of the Purchaser.

     Within 120 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Mortgage Loan Purchase Price. In the event
that a breach shall involve any representation or warranty set forth in Section
3.02 or 3.03 and such breach cannot be cured within 120 days of the earlier of
either discovery by or notice to the Originator of such breach, each Mortgage
Loan shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price, as such term is defined in the Pooling and Servicing Agreement.
The Originator may, at the request of the Purchaser and assuming the Originator
has a Qualified Substitute Mortgage Loan, rather than repurchase a deficient
Mortgage Loan as provided above, remove such Mortgage Loan and substitute in its
place a Qualified Substitute Mortgage Loan or Loans. If the Originator does not
provide a Qualified Substitute Mortgage Loan or Loans, it shall repurchase the
deficient Mortgage Loan. Any repurchase of a Mortgage Loan(s) pursuant to the
foregoing provisions of this Section 3.04 shall occur on a date designated by
the Purchaser and shall be accomplished by deposit in accordance with Section
2.03 of the Pooling and Servicing Agreement. Any repurchase or substitution
required by this Section shall be made in a manner consistent with Section 2.03
of the Pooling and Servicing Agreement.

     At the time of substitution or repurchase of any deficient Mortgage Loan,
the Purchaser and the Originator shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Originator and the delivery to
the Originator of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Originator shall, simultaneously with such deposit, give
written notice to the Purchaser that such deposit has taken place. Upon such
repurchase, the Mortgage Loan Schedule shall be amended to reflect the
withdrawal of the repurchased Mortgage Loan from this Agreement.

     As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing Agreement, with the Mortgage Note endorsed as required
therein. The Originator shall deposit in the Collection Account the Monthly
Payment less the Servicing Fee due on such Qualified Substitute Mortgage Loan or
Loans in the month following the date of such substitution. Monthly Payments due
with respect to Qualified Substitute Mortgage Loans in the month of substitution
will be retained by the Originator. For the



                                       18
<PAGE>

month of substitution, distributions to the Purchaser will include the Monthly
Payment due on such Deleted Mortgage Loan in the month of substitution, and the
Originator shall thereafter be entitled to retain all amounts subsequently
received by the Originator in respect of such Deleted Mortgage Loan. Upon such
substitution, the Qualified Substitute Mortgage Loans shall be subject to the
terms of this Agreement in all respects, and the Originator shall be deemed to
have made with respect to such Qualified Substitute Mortgage Loan or Loans as of
the date of substitution, the covenants, representations and warranties set
forth in Sections 3.01, 3.02 and 3.03.

     It is understood and agreed that the representations and warranties set
forth in Section 3.01 shall survive delivery of the respective Mortgage Files to
the Trustee on behalf of the Purchaser.

     It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS


     Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby covenants
that except for the transfer hereunder, neither the Originator nor the Seller
will 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 Originator 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 Originator will defend the right, title and interest of the
Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or 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 Originator or 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.

                                   ARTICLE V.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS


     Section 5.01 INDEMNIFICATION.

          (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or




                                       19
<PAGE>

liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator or the omission or
the alleged omission to state therein a material fact necessary in order to make
the statements in the Prospectus Supplement or any amendment or supplement to
the Prospectus Supplement approved in writing by the Originator, in the light of
the circumstances under which they were made, not misleading, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission relates to the Originator Information contained in the
Prospectus Supplement, (ii) any untrue statement or alleged untrue statement of
any material fact contained in the information on any computer tape furnished to
the Purchaser or an affiliate thereof by or on behalf of the Originator
containing information regarding the assets of the Trust or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
information provided by the Originator to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to KPMG LLP or prospective investors (directly or
indirectly through available information systems) in connection with the
issuance, marketing or offering of the Certificates. This indemnity agreement
will be in addition to any liability which the Originator may otherwise have.

          (b) The Purchaser agrees to indemnify and hold harmless the Seller and
the Originator, each of their respective officers, directors and each person or
entity who controls the Seller, the Originator or any such person, against any
and all losses, claims, damages or liabilities, joint and several, to which the
Seller, the Originator or any such person or entity may become subject, under
the Securities Act or otherwise, and will reimburse the Seller and/or the
Originator for any legal or other expenses incurred by the Seller, the
Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.

          (c) Promptly after receipt by any indemnified party under this Article
V of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying




                                       20
<PAGE>

party shall not relieve it from any liability which it may have to any
indemnified party otherwise than under this Article V.

     If any such claim or action shall be brought against an indemnified party,
and it shall notify the indemnifying party thereof, the indemnifying party shall
be entitled to participate therein and, to the extent that it wishes, jointly
with any other similarly notified indemnifying party, to assume the defense
thereof with counsel reasonably satisfactory to the indemnified party. After
notice from the indemnifying party to the indemnified party of its election to
assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Article V for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     Any indemnified party shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

     Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent to a settlement of any action, the indemnifying
party agrees that it shall be liable for any settlement of any proceeding
effected without its written consent if such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid request
and the indemnifying party has not previously provided the indemnified party
with written notice of its objection to such settlement. No indemnifying party
shall effect any settlement of any pending or threatened proceeding in respect
of which an indemnified party is or could have been a party and indemnity is or
could have been




                                       21
<PAGE>

sought hereunder, without the written consent of such indemnified party, unless
settlement includes an unconditional release of such indemnified party from all
liability and claims that are the subject matter of such proceeding.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Article is
for any reason held to be unenforceable although applicable in accordance with
its terms, the Seller and the Originator, on the one hand, and the Purchaser, on
the other, shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement
incurred by the Seller, the Originator and the Purchaser in such proportions as
shall be appropriate to reflect the relative benefits received by the Seller and
the Originator on the one hand and the Purchaser on the other from the sale of
the Mortgage Loans such that the Purchaser is responsible for the lesser of (i)
0.25% thereof and (ii) 0.25% of the aggregate proceeds to the Seller from the
sale of the Mortgage Loans and the Originator shall be responsible for the
balance; PROVIDED, HOWEVER, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section, each officer and
director of the Purchaser and each person, if any, who controls the Purchaser
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Purchaser, each director of the Originator, each
officer of the Originator, and each person, if any, who controls the Originator
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Originator and each director of the Seller, each
officer of the Seller, and each person, if any, who controls the Seller within
the meaning of Section 15 of the Securities Act shall have the same rights to
contribution as the Seller.

          (e) The Originator agrees to indemnify and to hold each of the
Purchaser, the Trustee, each of the officers and directors of each such entity
and each person or entity who controls each such entity or person and each
Certificateholder harmless against any and all claims, losses, penalties, fines,
forfeitures, legal fees and related costs, judgments, and any other costs, fees
and expenses that the Purchaser, the Trustee, or any such person or entity and
any Certificateholder may sustain in any way (i) related to the failure of the
Originator to perform its duties in compliance with the terms of this Agreement,
(ii) arising from a breach by the Originator of its representations and
warranties in Section 3.01, 3.02 or 3.03 of this Agreement or (iii) related to
the origination or prior servicing of the Mortgage Loans by reason of any acts,
omissions, or alleged acts or omissions of the Originator, the Seller or any
servicer. The Originator shall immediately notify the Purchaser, the Trustee and
each Certificateholder if a claim is made by a third party with respect to this
Agreement. The Originator shall assume 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 Purchaser, the Trustee or any such person or entity and/or any
Certificateholder in respect of such claim.

                                   ARTICLE VI.

                                   TERMINATION

     Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, then such covenants, agreements, provisions

enforceability of the other provisions of this Agreement.

     Section 7.05 COUNTERPARTS. This Agreement may be executed in one or more
counterparts and 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, the Seller and the
Originator 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 Originator
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
Originator 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 Originator 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 pledging the Mortgage Loans 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

rights relate to Mortgage Loans transferred to the Trustee and to the
enforcement or exercise of any right or remedy against the Seller or the
Originator 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

agreements herein made on the part of the Seller is made and intended not as

Company but is made and intended for the purpose of binding only the Seller, (c)
nothing herein contained shall be construed as creating any liability on
Wilmington Trust Company, individually or personally, to perform any covenant
either expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties to this Agreement and by any person claiming by,
through or under the parties to this Agreement and (d) under no circumstances

     The Purchaser hereby acknowledges its acceptance of all right, title and
interest to the Mortgage Loans and other property, now existing and hereafter
created, conveyed to it pursuant to Section 2.01.

     The parties hereto intend that the transaction set forth herein be a sale
by the Seller to the Purchaser of all the Seller's right, title and interest in

grants to the Purchaser a security interest in all of the Seller's right, title
and interest in, to and under the Mortgage Loans and other property described
above, whether now existing or hereafter created, to secure all of the Seller's
obligations hereunder; and this Agreement shall constitute a security agreement
under applicable law.

     The Originator shall cause the Assignments which were delivered in blank to
be completed and shall cause all Assignments referred to in Section 2.02(iii)
hereof and, to the extent necessary, in Section 2.02(iv) hereof to be recorded.
The Originator shall be required to deliver such Assignments for recording
within 90 days of the Closing Date. Notwithstanding the foregoing, however, for
administrative convenience and facilitation of servicing and to reduce closing
costs, the Assignments of Mortgage shall not be required to be submitted for
recording with respect to any Mortgage Loan in any jurisdiction where the Rating
Agencies do not require recordation in order to receive the ratings on the
Certificates at the time of their initial issuance; PROVIDED, HOWEVER, each
Assignment shall be submitted for recording by the Originator in the manner
described above, at no expense to the Trust Fund or Trustee, upon the earliest
to occur of:




                                       4
<PAGE>

(i) reasonable direction by Holders of Certificates entitled to at least 25% of
the Voting Rights, or the NIMS Insurer, (ii) the occurrence of a Master Servicer
Event of Termination, (iii) the occurrence of a bankruptcy, insolvency or
foreclosure relating to the Master Servicer, (iv) the occurrence of a servicing
transfer as described in Section 7.02 hereof, (v) if the Originator is not the
Master Servicer and with respect to any one Assignment the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Mortgagor under the
related Mortgage and (vi) any Mortgage Loan that is 90 days or more Delinquent.
Upon (a) receipt of written notice from the Trustee that recording of the
Assignments is required pursuant to one or more of the conditions (excluding (v)
and (vi) above) set forth in the preceding sentence or (b) upon the occurrence
of condition (v) or (vi) in the preceding sentence, the Originator shall be
required to deliver such Assignments for recording as provided above, promptly
and in any event within 30 days following receipt of such notice.
Notwithstanding the foregoing, if the Originator fails to pay the cost of
recording the Assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust. The Originator shall
furnish the Trustee, or its designated agent, with a copy of each Assignment
submitted for recording. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Originator 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. In the event

the Mortgage Loan;

          (b) Immediately prior to the transfer and assignment to the Purchaser,
the Mortgage Note and the Mortgage Loan were not subject to an assignment or
pledge, and the Seller has full right and authority to sell and assign the
Mortgage Loan;

          (c) The Seller is transferring such Mortgage Loan to the Purchaser
free and clear of any and all liens, pledges, charges or security interests of
any nature encumbering the Mortgage Loans;

otherwise dealt with by the Originator and any affiliate of the Originator in
compliance with all applicable federal, state and local laws and regulations,
including, but not limited to, all applicable predatory and abusive lending laws
and the terms of the related Mortgage Note and Mortgage;

          (f) The related Mortgage Note and Mortgage are genuine and each is the
legal, valid and binding obligation of the maker thereof, enforceable in
accordance with its terms except as such enforcement may be limited by
bankruptcy, insolvency, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and by general equity principles
(regardless of whether such enforcement is considered in a proceeding in equity
or at law);



                                       6
<PAGE>


          (g) The related Mortgage is a valid and enforceable first or second
lien on the related Mortgaged Property, which Mortgaged Property is free and
clear of all encumbrances and liens (including mechanics liens) having priority
over the first or second lien of the Mortgage except for: (i) liens for real
estate taxes and assessments not yet due and payable; (ii) covenants, conditions
and restrictions, rights of way, easements and other matters of public record as
of the date of recording of such Mortgage, such exceptions appearing of record
being acceptable to mortgage lending institutions generally or specifically
reflected or considered in the lender's title insurance policy delivered to the
originator of the Mortgage Loan and referred to in the appraisal made in
connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

          (h) Any security agreement, chattel mortgage or equivalent document
related to such Mortgage Loan establishes and creates a valid and enforceable
first or second lien on the Mortgaged Property;

          (i) As of the last calendar day of May 2003 and with respect to any
Mortgage Loan that had a payment due on or before May 1, 2003, except with
respect to 3.93% of the Mortgage Loans by the aggregate Cut-off Date Principal
Balance of the Mortgage Loans, the related Monthly Payment due on May 1, 2003
has been received. In addition, 0.00% of the Mortgage Loans have been 30 or more
days delinquent in the last 12 months and 0.00% of the Mortgage Loans have been
30 or more days delinquent for two payment periods in the last 12 months;

          (j) Neither the Originator nor the Seller has advanced funds, or
induced, solicited or knowingly received any advance of funds by a party other
than the Mortgagor, directly or indirectly, for the payment of any amount
required under the Mortgage Loan;

          (k) Neither the Originator nor the Seller has impaired, waived,
altered or modified the related Mortgage or Mortgage Note in any material
respect, or satisfied, canceled, rescinded or subordinated such Mortgage or
Mortgage Note in whole or in part or released all or any material portion of the
Mortgaged Property from the lien of the Mortgage, or executed any instrument of
release, cancellation, rescission or satisfaction of the Mortgage Note or
Mortgage;

          (l) As of the Cut-off Date, the Mortgage has not been satisfied,
canceled or subordinated, in whole or in part, or rescinded, and the Mortgaged
Property has not been released from the lien of the Mortgage, in whole or in
part (except for a release that does not materially impair the security of the
Mortgage Loan or a release the effect of which is reflected in the Loan-to-Value
Ratio or combined Loan-to-Value Ratio for the Mortgage Loan as set forth in the
Schedule of Mortgage Loans), nor has any instrument been executed that would
effect any such release, cancellation, subordination or rescission;

          (m) No Mortgage Loan is subject to any right of recission, set-off,
counterclaim or defense, including the defense of usury, nor will the operation
of any of the terms of any Mortgage Note or Mortgage, or the exercise of any
right thereunder, render either the Mortgage Note or Mortgage unenforceable in
whole or in part, or subject to any right of recission, set-off, counterclaim or
defense,




                                       7
<PAGE>

including the defense of usury, and no such right of recission, set-off,
counterclaim or defense has been asserted with respect thereto;

          (n) To the Originator's knowledge, there is no proceeding pending for
the total or partial condemnation and no eminent domain proceedings pending
affecting any Mortgaged Property;

          (o) Each Mortgage Loan is covered by either (i) a mortgage title
insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged Property is
located, an attorney's opinion of title given by an attorney licensed to
practice law in the jurisdiction where the Mortgaged Property is located. All of
the Originator's rights under such policies, opinions or other instruments shall
be transferred and assigned to Purchaser upon sale and assignment of the
Mortgage Loans hereunder. The title insurance policy has been issued by a title
insurer licensed to do business in the jurisdiction where the Mortgaged Property
is located, insuring the original lender, its successor and assigns, as to the
first or second priority lien of the Mortgage in the original principal amount
of the Mortgage Loan, subject to the exceptions contained in such policy. The
Originator is the sole insured of such mortgagee title insurance policy, and
such mortgagee title insurance policy is in full force and effect and will be in
force and effect upon the consummation of the transactions contemplated by this
Agreement. Neither the Originator nor any affiliate of the Originator has made,
and the Originator has no knowledge of, any claims under such mortgagee title
insurance policy. The Originator is not aware of any action by a prior holder
and neither the Originator nor any affiliate of the Originator has done, by act
or omission, anything which could impair the coverage or enforceability of such
mortgagee title insurance policy or the accuracy of such attorney's opinion of
title;

          (p) There is no material default, breach, violation or event of
acceleration existing under the related Mortgage or the related 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 material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

          (q) With respect to any Mortgage Loan which provides for an adjustable
interest rate, all rate adjustments have been performed in accordance with the
terms of the related Mortgage Note or subsequent modifications, if any;

          (r) To the Originator's knowledge, there are no delinquent taxes,
ground rents, water charges, sewer rents, assessments, insurance premiums,
leasehold payments, including assessments payable in future installments or
other outstanding charges, affecting the related Mortgaged Property;

          (s) No foreclosure proceedings are pending against the Mortgaged
Property and the Mortgage Loan is not subject to any pending bankruptcy or
insolvency proceeding, and to the Originator's best knowledge, no material
litigation or lawsuit relating to the Mortgage Loan is pending;



                                       8
<PAGE>

          (t) The Mortgage Loan obligates the mortgagor thereunder to maintain a
hazard insurance policy ("Hazard Insurance") in an amount at least equal to the
lesser of (i) the maximum insurable value of such improvements or (ii) the
principal balance of the Mortgage Loan with a standard mortgagee clause, in
either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

          (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

          (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
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 (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

          (w) Except as set forth in the appraisal which forms part of the
related Mortgage File, the Mortgaged Property, normal wear and tear excepted, is
undamaged by waste, fire, earthquake or earth movement, windstorm, flood,
tornado or other casualty so as to affect materially and adversely the value of
the Mortgaged Property as security for the Mortgage Loan or the use for which
the premises were intended;

          (x) To the Originator's knowledge, there was no fraud involved in the
origination of the Mortgage Loan by the mortgagee or by the Mortgagor, any
appraiser or any other party involved in the origination of the Mortgage Loan;



                                       9
<PAGE>


          (y) Each Mortgage File contains an appraisal of the 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
performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

          (z) To the best of the Originator's knowledge, all parties which have
had any interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee
or otherwise, are (or, during the period in which they held and disposed of such
interest, were) in compliance with any and all applicable "doing business" and
licensing requirements of the laws of the state wherein the Mortgaged Property
is located;

          (aa) No improvements on the related Mortgaged Property (upon which
value was given) 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 the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

          (bb) Each Mortgage Loan was originated or acquired by a savings and
loan association, a savings bank, a commercial bank or similar banking
institution which is supervised and examined by a federal or state authority, or
by a mortgagee approved by the Secretary of HUD. Each Mortgage Loan was
originated substantially in accordance with the Originator's underwriting
criteria, which are at least as stringent as the underwriting criteria set forth
in the Prospectus Supplement. Each Mortgage Loan is currently being serviced by
the Originator and has been serviced by the Originator since the date of
origination of such Mortgage Loan;

          (cc) (i) Principal payments on the Mortgage Loan commenced no more
than two months after the proceeds of the Mortgage Loan were disbursed and (ii)
each Mortgage Note is payable on the first day of each month;

          (dd) Other than with respect to not more than 0.08% of the Mortgage
Loans (by aggregate principal balance of the Mortgage Loans as of the Cut-off
Date), which are "balloon payment" mortgage loans, each Mortgage Loan is fully
amortizing;

          (ee) The Mortgage Loan bears interest at the Mortgage Rate and the
Mortgage Note does not permit negative amortization. No Mortgage Loan bearing
interest at an adjustable rate permits the Mortgagor to convert the Mortgage
Loan to a fixed rate Mortgage Loan;

          (ff) With respect to escrow deposits, if any, all such payments are in
the possession of, or under the control of, the Master Servicer and there exist
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 Master Servicer have been capitalized under
any Mortgage or the related Mortgage Note;

          (gg) No Mortgage Loan contains provisions pursuant to which scheduled
payments are: (i) paid or partially paid with funds deposited in any separate
account established by the Originator, the




                                       10
<PAGE>

Seller, the Mortgagor, or anyone on behalf of the Mortgagor; or (ii) paid by any
source other than the Mortgagor or 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;

          (hh) As of the origination date of each Mortgage Loan, the related
Mortgaged Property is lawfully permitted to be occupied under applicable law;

          (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

          (jj) No Mortgage Loan was made in connection with (a) the construction
or rehabilitation of a Mortgaged Property or (b) facilitating the trade-in or
exchange of a Mortgaged Property;

          (kk) 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;

          (ll) There are no mechanics' or similar liens or claims that 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 that are
or may be liens prior to, or equal or coordinate with, the lien of the related
Mortgage;

          (mm) As to each Mortgage Loan, interest is calculated on the Mortgage
Note on the basis of twelve 30-day months and a 360 day year;

          (nn) The Mortgaged Property consists of one of the following: detached
or semi-detached one- to four-family dwelling units, townhouses, individual
condominium units and individual units in planned unit developments, or
manufactured homes;

          (oo) Each Mortgage Loan constitutes a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code;

          (pp) The Mortgage Loans were not intentionally selected by the Seller
in a manner intended to adversely affect the Purchaser or the Trust;



                                       11
<PAGE>


          (qq) The representations, warranties and covenants, set forth in this
Section shall survive the Closing Date;

          (rr) The Mortgage Loans have original terms to maturity ranging from
10 to 30 years;

          (ss) With respect to the Mortgage Loans, no more than 20.47%; 15.42%;
10.69%; 6.66% and 4.93% of the Mortgage Loans, by Cut-off Date Principal Balance
will be secured by Mortgaged Properties located in California, New York,
Massachusetts, Florida and New Jersey, respectively; and 75.15% of the Mortgage
Loans, by Cut-off Date Principal Balance will be secured by real property with a
single family residence erected thereon and 3.98% of the Mortgage Loans, by the
Cut-off Date Principal Balance are secured by condominiums;

          (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 100%;

          (uu) With respect to each Mortgage Loan, the Mortgage Note related
thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which will be
adjusted on each Adjustment Date to equal the Index plus the Gross Margin,
rounded to the nearest or next highest 0.125%, subject to the Periodic Rate Cap,
the Maximum Mortgage Rate and the Minimum Mortgage Rate;

          (vv) The average Cut-off Date Principal Balance of the Mortgage Loans
is $159,678.31;

          (ww) No Mortgage Loan is subject to the requirements of the Home
Ownership and Equity Protection Act of 1994 ("HOEPA"), nor any state law,
ordinance or regulation similar to HOEPA;

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

          (yy) No Mortgage Loan originated before October 1, 2002 has a
Prepayment Charge term longer than five years after its origination and no
Mortgage Loan originated on or after October 1, 2002 has a Prepayment Charge
term longer than three years after its origination;

          (zz) Each Group I Mortgage Loan had a Principal Balance at origination
which conformed with Fannie Mae/Freddie Mac guidelines.

          (aaa) Each Mortgage Loan conforms, and all Mortgage Loans in the
aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

          (bbb) With respect to second lien Mortgage Loans, either (a) no
consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File;



                                       12
<PAGE>

          (ccc) Each Mortgage Note is comprised of one original promissory note
and each such promissory note constitutes an "instrument" for purposes of
section 9-102(a)(65) of the UCC;

          (ddd) [Reserved];

          (eee) No borrower was encouraged or required to select a Group I
Mortgage Loan product offered by the Originator which is a higher cost product
designed for less creditworthy borrowers, unless at the time of the Group I
Mortgage Loan's origination, such borrower did not qualify taking into account
credit history and debt-to-income ratios for a lower-cost credit product then
offered by the Originator or any affiliate of the Originator. If, at the time of
loan application, the borrower may have qualified for a for a lower-cost credit
product then offered by any mortgage lending affiliate of the Originator, the
Originator referred the borrower's application to such affiliate for
underwriting consideration;

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

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

          (hhh) No borrower of a Group I Mortgage Loan was required to purchase
any credit life, disability, accident or health insurance product as a condition
of obtaining the extension of credit. No borrower obtained a prepaid
single-premium credit life, disability, accident or health insurance policy in
connection with the origination of the Group I Mortgage Loan;

          (iii) All points and fees related to each Group I Mortgage Loan were
disclosed in writing to the borrower in accordance with applicable state and
federal law. Except in the case of a Group I Mortgage Loan in an original
principal amount of less than $60,000 which would have resulted in an
unprofitable origination, no borrower was charged "points and fees" (whether or
not financed) in an amount greater than 5% of the principal amount of such loan,
such 5% limitation calculated in accordance with the Lender Letter. All fees and
charges (including finance charges) and whether or not financed, assessed,
collected or to be collected in connection with the origination and servicing of
each Group I Mortgage Loan




                                       13
<PAGE>


has been disclosed in writing to the borrower in accordance with applicable
state and federal law and regulation;

          (kkk) No Mortgage Loan is a "High Cost Home Loan" as defined in the

located in the State of Georgia was originated (or modified) on or after October
1, 2002 through and including March 6, 2003;

          (lll) Each Group I Mortgage Loan is in compliance with the
anti-predatory lending eligibility for purchase requirements of the Fannie Mae
Lender Letter, LL03-00: Eligibility of Mortgages to Borrowers with Blemished
Credit Records (04/11/00) other than the requirements regarding Escrow Deposit
Accounts;

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

          (nnn) None of the Mortgage Loans are High Cost as defined by the

Property is located to the extent necessary to ensure the enforceability of each

               (iii) The execution and delivery of this Agreement by the
Originator and the performance of and compliance with the terms of this

                                       14
<PAGE>

material contract, agreement or other instrument to which the Originator is a
party or which may be applicable to the Originator or its assets;

               (iv) The Originator is not in violation of, and the execution and
delivery of this Agreement by the Originator 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 over the Originator
or its assets, which violation might have consequences that would materially and
adversely affect the condition (financial or otherwise) or the operation of the
Originator or its assets or might have consequences that would materially and
adversely affect the performance of its obligations and duties hereunder;

               (v) The Originator is a HUD approved mortgagee pursuant to
Section 203 and Section 211 of the National Housing Act. No event has occurred,
including but not limited to a change in insurance coverage, which would make
the Originator unable to comply with HUD eligibility requirements or which would
require notification to HUD;

               (vi) The Originator does not believe, nor does it have any reason
or cause to believe, that it cannot perform each and every covenant contained in
this Agreement;

               (vii) There are no actions or proceedings against, or
investigations known to it of, the Originator before any court, administrative
or other tribunal (A) that might prohibit its entering into this Agreement, (B)
seeking to prevent the sale of the Mortgage Loans or the consummation of the
transactions contemplated by this Agreement or (C) that might prohibit or
materially and adversely affect the performance by the Originator of its
obligations under, or validity of enforceability of, this Agreement;

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

               (ix) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Originator. The sale of
the Mortgage Loans was in the ordinary course of business of the Originator and
the assignment and conveyance of the Mortgage Notes and the Mortgages by the
Originator are not subject to the bulk transfer or any similar statutory
provisions;

               (x) The information delivered by the Originator to the Purchaser
with respect to the Originator's loan loss, foreclosure and delinquency
experience on mortgage loans underwritten to similar standards as the Mortgage

               (xi) Except with respect to any statement regarding the
intentions of the Purchaser, or any other statement contained herein the truth
or falsity of which is dependant solely upon the actions of the Purchaser, this
Agreement does not contain any untrue statement of material fact or omit to

misleading. The written




                                       15

statements, reports and other documents prepared and furnished or to be prepared
and furnished by the Originator pursuant to this Agreement or in connection with
the transactions contemplated hereby taken in the aggregate do not contain any
untrue statement of material fact or omit to state a material fact necessary to
make the statements contained therein not misleading; and

               (xii) The Originator has not transferred the Mortgage Loans with
any intent to hinder, delay or defraud any of its creditors.

the Closing Date or as of such other date specifically provided herein:

          (a) The Seller is duly organized, validly existing and in good

Property is located to the extent necessary to ensure the enforceability of each
Mortgage Loan in accordance with the terms of this Agreement;

          (b) The Seller has the full power and authority to hold each Mortgage
Loan, to sell each Mortgage Loan, to execute, deliver and perform, and to enter
into and consummate, all transactions contemplated by this Agreement. The Seller

authorization, execution and delivery by the Purchaser and the Originator,
constitutes a legal, valid and binding obligation of the Seller, enforceable
against it in accordance with its terms except as the enforceability thereof may
be limited by bankruptcy, insolvency or reorganization;

          (c) The execution and delivery of this Agreement by the Seller and the
performance of and compliance with the terms of this Agreement will not violate
the Seller's certificate of trust or constitute a default under or result in a
breach or acceleration of, any material contract, agreement or other instrument

assets;

          (d) The Seller is not in violation of, and the execution and delivery
of this Agreement by the Seller 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 over the Seller or its
assets, which violation might have consequences that would materially and
adversely affect the condition (financial or otherwise) or the operation of the

adversely affect the performance of its obligations and duties hereunder; and

          (e) Immediately prior to the payment of the Purchase Price for each
Mortgage Loan, the Seller was the owner of the related Mortgage and the
indebtedness evidenced by the related Mortgage Note and upon the payment of the
Purchase Price by the Purchaser, in the event that the Seller retains record
title, the Seller shall retain such record title to each Mortgage, each related
Mortgage Note and the related Mortgage Files with respect thereto in trust for
the Purchaser as the owner thereof;



                                       16

          (i) The consummation of the transactions contemplated by this

          (j) Except with respect to liens released immediately prior to the
transfer herein contemplated, each Mortgage Note and related Mortgage have not
been assigned or pledged and immediately prior to the transfer and assignment
herein contemplated, the Seller held good, marketable and indefeasible title to,
and was the sole owner and holder of, each Mortgage Loan subject to no liens,
charges, mortgages, claims, participation interests, equities, pledges or
security interests of any nature, encumbrances or rights of others
(collectively, a "Lien"); the Seller has full right and authority under all
governmental and regulatory bodies having jurisdiction over the Seller, subject
to no interest or participation of, or agreement with, any party, to sell and
assign the same pursuant to this Agreement; and immediately upon the transfers
and assignments herein contemplated, the Seller shall have transferred all of
its right, title and interest in and to each Mortgage Loan and the Trustee will
hold good, marketable and indefeasible title to, and be the sole owner of, each
Mortgage Loan subject to no Liens.

     Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It is
understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Originator or as to which the Originator has no
knowledge, if it is discovered that the substance of any such representation and
warranty is inaccurate and the inaccuracy materially and adversely affects the
value of the related Mortgage Loan, or the interest therein of the Purchaser or
the Purchaser's assignee, designee or transferee, then notwithstanding the
Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by




                                       17
<PAGE>

either the Originator, the Master Servicer or the Purchaser of a breach of any
of the foregoing representations and warranties that materially and adversely
affects the value of the Mortgage Loans or the interest of the Purchaser (or
which materially and adversely affects the interests of the Purchaser in the
related Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others. It is understood by the parties hereto that a
breach of the representations and warranties made in Section 3.01(ww), (xx) and
(jjj) will be deemed to materially and adversely affect the value of the related
Mortgage Loan or the interest of the Purchaser.

     Within 120 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Purchase Price. In the event that a breach
shall involve any representation or warranty set forth in Section 3.02 or 3.03
and such breach cannot be cured within 120 days of the earlier of either
discovery by or notice to the Originator of such breach, each Mortgage Loan
shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price, as such term is defined in the Pooling and Servicing Agreement.
The Originator may, at the request of the Purchaser and assuming the Originator
has a Qualified Substitute Mortgage Loan, rather than repurchase a deficient
Mortgage Loan as provided above, remove such Mortgage Loan and substitute in its
place a Qualified Substitute Mortgage Loan or Loans. If the Originator does not
provide a Qualified Substitute Mortgage Loan or Loans, it shall repurchase the
deficient Mortgage Loan. Any repurchase of a Mortgage Loan(s) pursuant to the
foregoing provisions of this Section 3.04 shall occur on a date designated by
the Purchaser and shall be accomplished by deposit in accordance with Section
2.03 of the Pooling and Servicing Agreement. Any repurchase or substitution
required by this Section shall be made in a manner consistent with Section 2.03
of the Pooling and Servicing Agreement.

     At the time of substitution or repurchase of any deficient Mortgage Loan,
the Purchaser and the Originator shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Originator and the delivery to
the Originator of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Originator shall, simultaneously with such deposit, give
written notice to the Purchaser that such deposit has taken place. Upon such
repurchase, the Mortgage Loan Schedule shall be amended to reflect the
withdrawal of the repurchased Mortgage Loan from this Agreement.

     As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing Agreement, with the Mortgage Note endorsed as required
therein. The Originator shall deposit in the Collection Account the Monthly
Payment less the Servicing Fee due on such Qualified Substitute Mortgage Loan or
Loans in the month following the date of such substitution. Monthly Payments due
with respect to Qualified Substitute Mortgage Loans in the month of substitution
will be retained by the Originator. For the month of substitution, distributions
to the Purchaser will include the Monthly Payment due on such Deleted



                                       18
<PAGE>

Mortgage Loan in the month of substitution, and the Originator shall thereafter
be entitled to retain all amounts subsequently received by the Originator in
respect of such Deleted Mortgage Loan. Upon such substitution, the Qualified
Substitute Mortgage Loans shall be subject to the terms of this Agreement in all
respects, and the Originator shall be deemed to have made with respect to such
Qualified Substitute Mortgage Loan or Loans as of the date of substitution, the
covenants, representations and warranties set forth in Sections 3.01, 3.02 and
3.03.

     It is understood and agreed that the representations and warranties set
forth in Section 3.01 shall survive delivery of the respective Mortgage Files to
the Trustee on behalf of the Purchaser.

     It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS


     Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby covenants
that except for the transfer hereunder, neither the Originator nor the Seller
will 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 Originator 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 Originator will defend the right, title and interest of the
Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or 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 Originator or 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.

                                   ARTICLE V.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS


     Section 5.01 INDEMNIFICATION.

          (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become



                                       19
<PAGE>

subject, under the Securities Act or otherwise, and will reimburse the
Purchaser, each such director and officer and each such controlling person for
any legal or other expenses incurred by the Purchaser or such controlling person
in connection with investigating or defending any such losses, claims, damages
or liabilities, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement of any material fact contained in the
Prospectus Supplement or any amendment or supplement to the Prospectus
Supplement approved in writing by the Originator or the omission or the alleged
omission to state therein a material fact necessary in order to make the
statements in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator, in the light of the
circumstances under which they were made, not misleading, but only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission relates to the Originator Information contained in the Prospectus
Supplement, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the information on any computer tape furnished to the
Purchaser or an affiliate thereof by or on behalf of the Originator containing
information regarding the assets of the Trust or (iii) any untrue statement or
alleged untrue statement of any material fact contained in any information
provided by the Originator to the Purchaser or any affiliate thereof, or any
material omission from the information purported to be provided hereby, and
disseminated to KPMG LLP or prospective investors (directly or indirectly
through available information systems) in connection with the issuance,
marketing or offering of the Certificates. This indemnity agreement will be in
addition to any liability which the Originator may otherwise have.

          (b) The Purchaser agrees to indemnify and hold harmless the Seller and
the Originator, each of their respective officers, directors and each person or
entity who controls the Seller, the Originator or any such person, against any
and all losses, claims, damages or liabilities, joint and several, to which the
Seller, the Originator or any such person or entity may become subject, under
the Securities Act or otherwise, and will reimburse the Seller and/or the
Originator for any legal or other expenses incurred by the Seller, the
Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.

          (c) Promptly after receipt by any indemnified party under this Article
V of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.



                                       20
<PAGE>



     If any such claim or action shall be brought against an indemnified party,
and it shall notify the indemnifying party thereof, the indemnifying party shall
be entitled to participate therein and, to the extent that it wishes, jointly
with any other similarly notified indemnifying party, to assume the defense
thereof with counsel reasonably satisfactory to the indemnified party. After
notice from the indemnifying party to the indemnified party of its election to
assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Article V for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     Any indemnified party shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

     Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent to a settlement of any action, the indemnifying
party agrees that it shall be liable for any settlement of any proceeding
effected without its written consent if such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid request
and the indemnifying party has not previously provided the indemnified party
with written notice of its objection to such settlement. No indemnifying party
shall effect any settlement of any pending or threatened proceeding in respect
of which an indemnified party is or could have been a party and indemnity is or
could have been sought hereunder, without the written consent of such
indemnified party, unless settlement includes an unconditional release of such
indemnified party from all liability and claims that are the subject matter of
such proceeding.



                                       21
<PAGE>



          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Article is
for any reason held to be unenforceable although applicable in accordance with
its terms, the Seller and the Originator, on the one hand, and the Purchaser, on
the other, shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement
incurred by the Seller, the Originator and the Purchaser in such proportions as
shall be appropriate to reflect the relative benefits received by the Seller and
the Originator on the one hand and the Purchaser on the other from the sale of
the Mortgage Loans such that the Purchaser is responsible for the lesser of (i)
0.25% thereof and (ii) 0.25% of the aggregate proceeds to the Seller from the
sale of the Mortgage Loans and the Originator shall be responsible for the
balance; PROVIDED, HOWEVER, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section, each officer and
director of the Purchaser and each person, if any, who controls the Purchaser
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Purchaser, each director of the Originator, each
officer of the Originator, and each person, if any, who controls the Originator
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Originator and each director of the Seller, each
officer of the Seller, and each person, if any, who controls the Seller within
the meaning of Section 15 of the Securities Act shall have the same rights to
contribution as the Seller.

          (e) The Originator agrees to indemnify and to hold each of the
Purchaser, the Trustee, each of the officers and directors of each such entity
and each person or entity who controls each such entity or person and each
Certificateholder harmless against any and all claims, losses, penalties, fines,
forfeitures, legal fees and related costs, judgments, and any other costs, fees
and expenses that the Purchaser, the Trustee, or any such person or entity and
any Certificateholder may sustain in any way (i) related to the failure of the
Originator to perform its duties in compliance with the terms of this Agreement,
(ii) arising from a breach by the Originator of its representations and
warranties in Section 3.01, 3.02 or 3.03 of this Agreement or (iii) related to
the origination or prior servicing of the Mortgage Loans by reason of any acts,
omissions, or alleged acts or omissions of the Originator, the Seller or any
servicer. The Originator shall immediately notify the Purchaser, the Trustee and
each Certificateholder if a claim is made by a third party with respect to this
Agreement. The Originator shall assume 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 Purchaser, the Trustee or any such person or entity and/or any
Certificateholder in respect of such claim.

                                   ARTICLE VI.

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 of
enforceability of the other provisions of this Agreement.

     Section 7.05 COUNTERPARTS. This Agreement may be executed in one or more
counterparts and 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, the Seller and the
Originator 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 Originator
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
Originator 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 Originator 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 pledging the Mortgage Loans 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 PURCHASE AGREEMENT. This
Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Originator, the Purchaser, the Trustee and the NIMs Insurer, if any.
The NIMs Insurer, if any, shall be a third party beneficiary hereof and may
enforce the terms hereof as if a party hereto. The obligations of the Seller and
the Originator under this Agreement cannot be assigned or delegated to a third
party without the consent of the Purchaser which consent shall be at the
Purchaser's sole discretion, except that the Purchaser acknowledges and agrees
that the Seller or the Originator may assign its obligations hereunder to any
Person into which the Seller or the




                                       24
<PAGE>



Originator is merged or any corporation resulting from any merger, conversion or
consolidation to which the Seller or the Originator is a party or any Person
succeeding to the business of the Seller or the Originator. 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 and the Originator each
acknowledge and consent to the assignment by the Purchaser to the Trustee of all
of the Purchaser's rights against the Seller and the Originator 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 or the Originator 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, 3.02 and 3.03 and the provisions of Article V hereof shall
survive the purchase of the Mortgage Loans hereunder.

     Section 7.10 OWNER TRUSTEE. It is expressly understood and agreed by the
parties to this Agreement that (a) this Agreement is executed and delivered by
Wilmington Trust Company, not individually or personally but solely as Owner
Trustee of the Seller, in the exercise of the powers and authority conferred and
vested in it as trustee, (b) each of the representations, undertakings and
agreements herein made on the part of the Seller is made and intended not as
personal representations, undertakings and agreements by Wilmington Trust
Company but is made and intended for the purpose of binding only the Seller, (c)
nothing herein contained shall be construed as creating any liability on
Wilmington Trust Company, individually or personally, to perform any covenant
either expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties to this Agreement and by any person claiming by,
through or under the parties to this Agreement and (d) under no circumstances
shall Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Seller or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaken by the
Seller under this Agreement or any other document.

                           LOSS MITIGATION PROCEDURES

          FAS 140 P &S RELEVANT PROVISIONS - RECOVERY FOR DEFAULT LOANS

COLLECTIONS DEPARTMENT PRE-FORECLOSURE PROCESS:

At 33 calendar days delinquent, all borrowers are sent a 30-day pre-foreclosure
demand letter. Borrowers in states that require more than a 30-day period are
given the amount of time specified by state law.

Borrowers who are unable to pay the total amount past due are reviewed for
foreclosure based upon the following criteria:

     "Early Indicator" default risk score. Those borrowers with risk scores that
suggest a strong statistical likelihood of continuing default, are approved for
foreclosure as soon as 48 hours after expiration of the demand letter
(approximately 64 calendar days delinquent).

     A.   Moderate risk with willingness and ability. Those borrowers with a
          moderate statistical likelihood of continuing default wh demonstrate a
          willingness and ability to pay (as defined above), are solicited for
          extended (up to 6 months) repayment plans in which a portion of all
          past due payments are divided equally by 6 and a monthly payment
          schedule is established which consists of a "good faith" payment of
          some portion of the past due amount, one regular monthly installment
          and 1/6th of the remaining past due amount.

     B.   Low risk with willingness and ability. Those borrowers with a low risk
          of continuing default are actively solicited for placement on a
          repayment plan and/or are granted additional time to resolve their
          financial difficulties informally in arrangement with a loan
          counselor. Foreclosure is not typically initiated if or until the loan
          becomes 90+ days delinquent and the borrower is unable or unwilling to
          continue to make reasonable repayment arrangements.

     C.   Broken repayment plans. Those borrowers who are placed on extended
          repayment plans but fail to make their scheduled payments are approved
          for foreclosure as soon as 48 hours after the payment plan is broken.

All borrowers are given all reasonable opportunities to pay the total amount
past due (including all contractually permitted fees and charges) prior to the
expiration of the 30 day demand letters. Borrowers who fail to contact Option
One collections when past due, who repeatedly break promises to pay, who have a
willingness but no financial ability, or apparent financial ability but no
willingness, may be referred to foreclosure at any time after the expiration of
the 30-day demand letter, without regard to any other factor, but as a general
rule, a loan is referred to foreclosure no later than the 120th day of
delinquency. The guidelines outlined herein presuppose at least some reasonable
degree of willingness and ability.

PRE-CONVEYANCE OF TITLE:

Initial contact is made for discovery of mortgagor's intent and a minimum
requirement of two attempted contacts per month is required. In general, contact
made or attempted within the first 48 hours establishes categories as follows:
Willingness and Ability, No Willingness or Willingness and No Ability. Each
category provides a subset of options for loss mitigation efforts and the
options are ranked within each category as follows:

     1.   Willingness and Ability -- Typically the mortgagor(s) reason for
          default is temporary and a foreseeable solution is probable. The
          standard options negotiated, ranked in priority are:

          A.   Full Reinstatement
          B.   Payoff
          C.   Standard 6 month payment plan
          D.   Extension of the payment plan
          E.   Forbearance
          F.   Pre-Sale/Pre-Foreclosure Sale
          G.   Short Payoff
          H.   Modification

     2.   No Willingness -- Typically the mortgagor(s) is unclear of options to
          mitigate default and avoidsall calls or is brief and discloses little
          when contact is made. In this category efforts are made to continue
          attempts to contact and/or counsel mortgagor(s). When no contact is
          made, Skip Tracing, promotional items and/or letters are mailed in
          attempts to stimulate communication.

     3.   Willingness and No Ability -- Mortgagor(s) want to save home or remedy
          the default, however do not have resources to do so. In this scenario,
          the standard options negotiated, ranked in priority are:

          A.   Payoff
          B.   Assumption
          C.   Pre-Sale/Pre-Foreclosure Sale
          D.   Short Payoff
          E.   Deed In Lieu of Foreclosure
          F.   Write-Off
          G.   Modification

Foreclosure process is also running parallel to the Loss Mitigation efforts and
in the event no workout is achieved then the Master Servicer obtains title
through foreclosure sale, from which the REO Department will attempt to seek
complete recovery from the sale of said property.

CONVEYANCE OF TITLE:

Once title is acquired as a result of foreclosure sale, Deed In Lieu of
Foreclosure or otherwise, the property is assigned to an REO Agent for complete

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 Class R Certificates (the "Certificate") issued pursuant
to the Pooling and Servicing Agreement (the "Agreement"), relating to the
above-referenced Certificates, among Option One Mortgage Acceptance Corporation,
as Depositor, Option One Mortgage Corporation, as Master Servicer (the "Master
Servicer") and Wells Fargo Bank Minnesota, National Association, as Trustee (the
"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 Certificate 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 Certificate 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) to 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 Certificate 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


                                       K-1

<PAGE>



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 Certificate 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 Certificate. 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
Certificate, 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 as Exhibit L 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
Certificate.

          8. The Transferee's taxpayer identification number is .

          9. The Transferee is a United States Person as defined in the
Agreement.

          10. The Transferee is aware that the Certificate may be a
"non-economic residual interest" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
non-economic 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 is it acting on
behalf of such a plan.

          I, _______________, the senior officer of Option One Mortgage
Acceptance Corporation (the "Registrant") in charge of securitizations, certify
that:

          l. I have reviewed this annual report on Form 10-K, and all reports on
Form 8-K containing distribution and servicing reports filed in respect of
periods included in the year covered by this annual report, of Registrant;

          2. Based on my knowledge, the information in these reports, taken as a
whole, does not contain any untrue statement of a material fact or omit to state
a material fact necessary to make the statements made, in light of the
circumstances under which such statements were made, not misleading as of the
last day of the period covered by this annual report;

          3. Based on my knowledge, the distribution or servicing information
required to be provided to the Trustee by the Master Servicer under the Pooling
and Servicing Agreement is included in these reports;

          4. Based on my knowledge and upon the annual compliance statement
included in the report and required to be delivered to the trustee in accordance
with the terms of the pooling and servicing, or similar, agreement, and except
as disclosed in the reports, the Master Servicer has fulfilled its obligations
under the servicing agreement; and

          5. The reports disclose all significant deficiencies relating to the
Master Servicer's compliance with the minimum servicing standards based upon the
report provided by an independent public accountant, after conducting a review
in compliance with the Uniform Single Attestation Program for Mortgage Bankers
or similar procedure, as set forth in the Pooling and Servicing Agreement that
is included in these reports.

          In giving the certifications above, I have reasonably relied on
information provided to me by the following unaffiliated parties: Wells Fargo
Bank Minnesota, National Association.
