         This Pooling and Servicing Agreement is dated as of October 1, 2000
(the "Agreement"), among OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as
depositor (the "Depositor"), OPTION ONE MORTGAGE CORPORATION, as master servicer
(the "Master Servicer") and WELLS FARGO BANK MINNESOTA, N.A., as trustee (the
"Trustee").

                             PRELIMINARY STATEMENT:

         The Depositor intends to sell pass-through certificates (collectively,
the "Certificates"), to be issued hereunder in multiple classes, which in the
aggregate will evidence the entire beneficial ownership interest in the Trust
Fund created hereunder. The Certificates will consist of seven classes of
certificates, designated as (i) the Class A Certificates, (ii) the Class M-1
Certificates, (iii) the Class M-2 Certificates, (iv) the Class M-3 Certificates,
(v) the Class P Certificates, (vi) the Class C Certificates and (vii) the Class
R Certificates.

                                     REMIC 1
                                     -------

         As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (exclusive of the Pre-Funding Account,
the Interest Coverage Account, the Reserve Fund and the Initial Deposit Account)
as a real estate mortgage investment conduit (a "REMIC") for federal income tax
purposes, and such segregated pool of assets will be designated as "REMIC 1."
The Class R-1 Interest will represent the sole class of "residual interests" in
REMIC 1 for purposes of the REMIC Provisions (as defined herein) 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 for purposes of satisfying Treasury regulation Section
1.860G-1(a)(4)(iii), the "latest possible maturity date" for each of the REMIC 1
Regular Interests. None of the REMIC 1 Regular Interests will be certificated.

         origination of the Mortgage Loan by an appraiser who met the minimum
         requirements of Fannie Mae and Freddie Mac, and (b) the value thereof
         as determined by a review appraisal conducted by the Originator in the

                      by a review appraisal conducted by the Originator in the
                      event any such review appraisal determines an appraised
                      value more than 10% lower than the value thereof, in the
                      case of a Mortgage Loan with a Loan-to-Value Ratio less

              (B)     in the case of a Mortgage Loan originated in connection
                      with a "lease option purchase," such value of the
                      Mortgaged Property is based on the lower of the value
                      determined by an appraisal made for the originator of such
                      Mortgage Loan at the time of origination or the sale price

                      price" was set less than 12 months prior to origination,
                      and is based on the value determined by an appraisal made
                      for the originator of such Mortgage Loan at the time of
                      the origination if the "lease option purchase price" was

Certificates and the Class R Certificates) shall be allocated among all Holders
of each such Class in proportion to the outstanding Certificate Principal
Balance of such Certificates and the Voting Rights allocated to the Class P
Certificates and the Class R Certificates shall be allocated among all Holders
of each such Class in proportion to such Holders' respective Percentage
Interest; PROVIDED, HOWEVER that when none of the Regular Certificates are
outstanding, 100% of the Voting Rights shall be allocated among Holders of the
Class R Certificates in accordance with such Holders' respective Percentage
Interests in the Certificates of such Class.

any distributions are taken into account such definition or calculation and any
related definitions or calculations shall be determined without duplication of

<PAGE>



              (iii) an original Assignment, in form and substance acceptable for

              recourse";

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

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

              (vi) the original or copies of each assumption, modification,

obligations of the Depositor to deliver such documents shall be deemed to be
satisfied upon (1) delivery to the Trustee or the Custodian no later than the
Closing Date (or Subsequent Closing Date, with respect to Subsequent Mortgage
Loans), of a copy of each such document certified by the Master Servicer, in its
capacity as Originator, in the case of (x) above or the applicable public

         Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Master
Servicer, in its capacity as Originator, shall have 90 days to cure such defect
or deliver such missing document to the Trustee or the Custodian.

         The Depositor (at the expense of the Master Servicer, in its capacity
as Originator) shall cause the Assignments which were delivered in blank and
cause to be completed and shall cause all Assignments referred to in Section
2.01(iii) hereof and, to the extent necessary, in Section 2.01(iv) hereof to be
recorded; PROVIDED, HOWEVER, the Depositor need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Depositor to
the Trustee and the Rating Agencies on or before the Closing Date, the
recordation of such assignment is not necessary to protect the Trustee's
interest in the related Mortgage Loan; PROVIDED, HOWEVER, notwithstanding the
delivery of any Opinion of Counsel, 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 direction
by Holders of Certificates entitled to at least 25% of the Voting Rights, (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)

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. 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 be required to deliver such assignments for recording within 45
days of the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans). 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), promptly following 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, N.A., as Trustee, without recourse."

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

         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 270 days of its submission for recordation. In the event that
the Master Servicer cannot provide a copy of such document certified by the
public recording office within such 270 day period, the Master Servicer shall
deliver to the Custodian, within such 270 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


                                       44

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 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.

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



                                       45

<PAGE>



         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 and the Master Servicer. In addition, upon the discovery by the
Originator, the Depositor 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 and the Master Servicer of such defect, missing document or breach
and request that the Originator deliver such missing document or cure such
defect or breach within 90 days from the date the Originator was notified of
such missing document, defect or breach, and if the Originator does not deliver
such missing document or cure such defect or breach in all material respects
during such period, the 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 90 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 90 day period, if the Originator
shall have commenced to cure such breach within such 90 day period, the
Originator shall be permitted to proceed thereafter diligently and expeditiously
to cure the same within the additional period provided under the Mortgage Loan
Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall
be deposited in the Collection Account, and the Trustee, upon receipt of written
certification from the 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


                                       46

<PAGE>



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) Subject to Section 2.03(e), within 90 days of the earlier of
discovery by the Depositor or receipt of notice by the Depositor of the breach
of any representation or warranty of the Depositor set forth in Section 2.06
with respect to any Mortgage Loan, which materially adversely affects the value
of such Mortgage Loan or the interest therein of the Certificateholders, the
Depositor shall (i) cure such breach in all material respects, (ii) repurchase
the Mortgage Loan from the Trust at the Purchase Price or (iii) cause such
Mortgage Loan to be removed from the Trust Fund (in which case it shall become a
Deleted Mortgage Loan) and substituted for by one or more Qualified Substitute
Mortgage Loans by the Originator in the manner and subject to the limitations
set forth in Section 2.03(d). The Purchase Price for any repurchased Mortgage
Loan shall be delivered to the Master Servicer for deposit in the Collection
Account, and, upon receipt thereof, the Master Servicer shall at the Depositor's
direction release to the Depositor the related Mortgage File and the Trustee
shall execute and deliver such instruments of transfer or assignment furnished
by the Depositor, in each case without recourse, as the Depositor shall furnish
to it and as shall be necessary to vest in the Depositor any Mortgage Loan
released pursuant hereto.

         (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, 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 a certification substantially in the form of Exhibit F-2
hereto with


                                       47

<PAGE>



respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Qualified
Substitute Mortgage Loans in the month of substitution are not part of 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 that such substitution has taken place, shall amend the
Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from
the terms of this Agreement and the substitution of the Qualified Substitute
Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan
Schedule to the Trustee. 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 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 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 Mortgage Loan's
status as a non-



                                       48
<PAGE>


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.

         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

         which the Master Servicer or its property is subject;

              (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

              (v)     [Reserved];

              (vi) The Master Servicer does not believe, nor does it have any

         pending or, to its knowledge, threatened against the Master Servicer
         that, either individually or in the aggregate, (A) may result in any

         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

         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; and

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

         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
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 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 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 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 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 Origiantor 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
         creditors' rights in general an 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




                                       51
<PAGE>

         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 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;

         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 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




                                       52
<PAGE>

         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 Account, 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) principal due and interest accruing on the Subsequent
Mortgage Loans after the related 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 shall be delivered to the Trustee at least three Business Days
prior to the related Subsequent Transfer Date.

              The purchase price paid by the Trustee from amounts released from
the Pre-Funding Account shall be one-hundred percent (100%) of the aggregate
Stated Principal Balance of the Subsequent Mortgage Loans so transferred (as
identified on the Mortgage Loan Schedule provided by the Depositor). This
Agreement shall constitute a fixed-price purchase contract in accordance with
Section 860G(a)(3)(A)(ii) of the Code.




                                       53
<PAGE>

              (b) The Depositor shall transfer to the Trustee for deposit in the
Mortgage Pool the Subsequent Mortgage Loans and the other property and rights
related thereto as described in paragraph (a) above, and the Trustee shall
release funds from the Pre-Funding Account, only upon the satisfaction of each
of the following conditions on or prior to the related Subsequent Transfer Date:

              (i) the Depositor shall have provided the Trustee and the Rating
         Agencies with a timely Addition Notice and shall have provided any
         information reasonably requested by the Trustee with respect to the
         Subsequent Mortgage Loans;

              (ii) the Depositor shall have delivered to the Trustee a duly

         least three Business Days prior to the related Subsequent Transfer
         Date;

              (iii) as of each Subsequent Transfer Date, as evidenced by
         delivery of the Subsequent Transfer Instrument, substantially in the
         form of Exhibit N, the Depositor shall not be insolvent nor shall it
         have been rendered insolvent by such transfer nor shall it be aware of
         any pending insolvency;

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

              (v) the Funding Period shall not have terminated;

              (vi) the Depositor shall not have selected the Subsequent Mortgage

              (vii) the Depositor shall have delivered to the Trustee and a
         Subsequent Transfer Instrument confirming the satisfaction of the

         the Subsequent Transfer Instrument, assigned to the Trustee without
         recourse for the benefit of the Certificateholders all the right, title
         and interest of the Depositor, in, to and under the Subsequent Mortgage
         Loan Purchase Agreement, to the extent of the Subsequent Mortgage
         Loans;

              (viii) with respect to the last Subsequent Transfer Date, the
         Depositor shall have delivered to the Trustee a letter from an
         Independent accountant (with copies provided to each Rating Agency)
         stating that the characteristics of the Subsequent Mortgage Loans

         Section 2.09.     CONVEYANCE OF REMIC REGULAR INTERESTS AND
                           ACCEPTANCE OF REMIC 1 BY THE TRUSTEE; ISSUANCE OF
                           CERTIFICATES.

         (a) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC 1 Regular Interests for the benefit of the holders of the
Certificates. The Trustee acknowledges receipt of the REMIC 1 Regular Interests
(which are uncertificated) and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the holders of the Certificates. The
interests evidenced by the Class R-2 Interest, together with the Regular
Certificates, constitute the entire beneficial ownership interest in REMIC 2.

         (b) In exchange for the REMIC 1 Regular Interests and, concurrently
with the assignment to the Trustee thereof, pursuant to the written request of
the Depositor executed by an officer of the Depositor, the Trustee has executed,
authenticated and delivered to or upon the order of the Depositor, the Regular
Certificates in authorized denominations evidencing (together with the Class R-2
Interest) the entire beneficial ownership interest in REMIC 2.

         (c) Concurrently with (i) the assignment and delivery to the Trustee of
REMIC 1 (including the Residual Interest therein represented by the Class R-1
Interest) and the acceptance by the Trustee thereof, pursuant to Section 2.01,
Section 2.02 and Section 2.09(a) and (ii) the assignment and delivery to the
Trustee of REMIC 2 (including the Residual Interest therein represented by the
Class R-2 Interest) and the acceptance by the Trustee thereof, pursuant to
Section 2.09(b), the Trustee, pursuant to the written request of the Depositor
executed by an officer of the Depositor, has executed, authenticated and
delivered to or upon the order of the Depositor, the Class R Certificates in
authorized denominations evidencing the Class R-1 Interest and the Class R-2
Interest.

         Section 2.10.     NEGATIVE COVENANTS OF THE TRUSTEE AND THE MASTER
                           SERVICER.

         Except as otherwise expressly permitted by this Agreement, the Trustee
and the Master Servicer shall not cause the Trust Fund to:

         (i) sell, transfer, exchange or otherwise dispose of any of the assets
of the Trust Fund;

         (ii) dissolve or liquidate the Trust Fund in whole or in part;

         (iii)engage, directly or indirectly, in any business other than that
arising out of the issue of the Certificates, and the actions contemplated or
required to be performed under this Agreement;

         (iv) incur, create or assume any indebtedness for borrowed money;

         (v) voluntarily file a petition for bankruptcy, reorganization,
assignment for the benefit of creditors or similar proceeding; or

                                   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:

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

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

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

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

         To the extent consistent with the foregoing, the Master Servicer (a)
shall seek to maximize the timely and complete recovery of principal and
interest on the Mortgage Notes and (b) shall waive (or permit a subservicer 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 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 and, if such waiver is made
in connection with a refinancing of the related Mortgage Loan, such refinancing
is related to a default or a reasonably foreseeable default 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 subservicer 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 required to be deposited
into the Collection Account. Notwithstanding any other provisions of this




                                       57
<PAGE>

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, 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 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
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




                                       58
<PAGE>

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 such agreements would not result in a withdrawal or a
downgrading by any Rating Agency of the rating on any Class of Certificates. 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
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 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




                                       59
<PAGE>

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 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.




                                       60
<PAGE>

         Section 3.05.     NO CONTRACTUAL RELATIONSHIP BETWEEN SUB-SERVICERS AND
                           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 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 the Mortgage Loans and held for its own account. Consistent with
the foregoing, the Master Servicer




                                       61
<PAGE>

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. 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. The Master Servicer's analysis supporting any forbearance and the
conclusion that any forbearance meets the standards of Section 3.01 (including
the standard that such forbearance will maximize the timely and complete
recovery of principal and interest on the Mortgage Notes) 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. xxxxx

         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




                                       62

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.

         Section 3.10.     COLLECTION ACCOUNT, INITIAL DEPOSIT 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






                                       63

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 and Liquidation 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 in
         connection with the Principal Prepayment of any of the Mortgage Loans;
         and

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

         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 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 3:00 p.m. New York time (i) on the Master
Servicer Remittance Date, that portion of the Available




                                       64
<PAGE>

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 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 3:00 p.m. New York time on such Business Day, withdraw from the
Collection Account any and all amounts payable or reimbursable to the 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.

              On behalf of the Trust Fund, the Trustee shall establish and
maintain the Initial Deposit Account, held in trust for the benefit of
Certificateholders. On the Closing Date, the Depositor shall remit or cause to
be remitted to the Trustee, for deposit in the Initial Deposit Account, and the
Trustee shall deposit the Initial Deposit, to the extent received by it, into
the Initial Deposit Account. The Initial Deposit Account shall be treated as an
"outside reserve fund" under applicable Treasury regulations and shall not be
part of any REMIC. Any investment earnings on funds in the Initial Deposit
Account shall be treated as owned by the Depositor and will be taxable to the
Depositor. The Trustee shall be required to withdraw such earnings from the
Initial Deposit Account and remit the same to the Depositor on the first
Distribution Date (or as soon as received if such funds are not available on
such Distribution Date), and shall thereupon terminate such account.

         (c) Funds in the Collection Account, the Initial Deposit 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 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 Master Servicer and the Depositor of the location of the Distribution
Account and the Initial Deposit 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, 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:




                                       65
<PAGE>

              (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;

              (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 and Insurance
         Proceeds received with respect to such Mortgage Loan, and (c) any
         Servicing




                                       66
<PAGE>

         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 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.

         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 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;

         Section 3.12.     INVESTMENT OF FUNDS IN THE INTEREST COVERAGE ACCOUNT,
                           COLLECTION ACCOUNT INITIAL DEPOSIT ACCOUNT AND THE
                           DISTRIBUTION ACCOUNT.

         (a) The Master Servicer may direct any depository institution
maintaining the Interest Coverage Account and the Collection Account, at the
direction of the Depositor the Trustee shall direct any depository institution
maintaining the Initial Deposit Account and at the direction of the Master
Servicer the Trustee shall direct any depository institution maintaining the
Distribution Account (each such account, for purposes of this Section 3.12, an
"Investment Account"), to invest the funds in such Investment Account in one or
more Permitted Investments bearing interest or sold at a discount, and maturing,
unless payable on demand, (i) no later than the Business Day immediately
preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Trustee is the
obligor thereon 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 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 Interest Coverage Account, the Initial Deposit
Account and 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




                                       68
<PAGE>

                      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 Interest Coverage Account, 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 Interest Coverage Account, 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. All income and gain realized
from the investment of funds deposited in the Initial Deposit Account shall be
for the benefit of the Depositor. The Depositor shall remit from its own funds
to the Trustee for deposit in the Initial Deposit 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.

         (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 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




                                       69
<PAGE>

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 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 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




                                       70
<PAGE>

shall be deemed to have complied with this provision if an Affiliate of the
Master Servicer has such errors and omissions and fidelity bond coverage and, by
the terms of such insurance policy or fidelity bond, the coverage afforded
thereunder extends to the Master Servicer. Any such errors and omissions policy
and fidelity bond shall by its terms not be cancelable without thirty days'
prior written notice to the Trustee. The Master Servicer shall also cause each
Sub-Servicer to maintain a policy of insurance covering errors and omissions and
a fidelity bond which would meet such requirements.

         Section 3.15.     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
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).




                                       71
<PAGE>

         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, consistent with
Servicing Standard, to foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Mortgage Loans (including 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 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




                                       72
<PAGE>

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.

         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) The Master Servicer may at its option purchase from the Mortgage
Pool, any Mortgage Loan or related REO Property that is 90 days or more
delinquent, which the Master Servicer determines in good faith will otherwise
become subject to foreclosure proceedings (evidence of such determination to be
delivered in writing to the Trustee prior to purchase), at a price equal to the
Purchase Price; PROVIDED, HOWEVER, that the Master Servicer shall purchase any
such Mortgage Loans or related REO Properties on the basis of delinquency,
purchasing the most delinquent Mortgage Loans or related REO Properties first.
The Purchase Price for any Mortgage Loan or related REO Property purchased
hereunder shall be deposited in the Distribution Account, and the Trustee, upon
receipt of such deposit, shall release or cause to be released to the Master
Servicer the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as the
Master Servicer shall furnish and as shall be necessary to vest in the Master
Servicer title to any Mortgage Loan or related REO Property released pursuant
hereto.

         (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan,
will be applied in the following order of priority: FIRST, to 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).




                                       73
<PAGE>

         (e) If the Master Servicer determines that it is in the best economic
interest of the Certificateholders to sell a Mortgage Loan that is over 90 days
Delinquent, rather than foreclosing, the Master Servicer may effect such a sale.
The net proceeds of such sale shall be Liquidation Proceeds.

         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 two executed copies of 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 five
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
of two copies 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, 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 two copies of a Request
for Release 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




                                       74
<PAGE>

Account have been so deposited, or that such Mortgage Loan has become an REO
Property, one copy of such Request for Release with respect to such Mortgage
Loan shall be released by the Trustee to the Master Servicer or its designee.

         (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 or
Liquidation 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. 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.





                                       75
<PAGE>

         Not later than twenty days after each Distribution Date, the Master
Servicer shall forward, 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 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 and the Depositor not
later than 90 days following the end of the fiscal year of the Master Servicer
(which, as of the Closing Date, ends on the last day of April), commencing in
2001, an Officers' Certificate stating, as to each signatory thereof, that (i) a
review of the activities of the Master Servicer during the preceding year and of
performance under this Agreement has been made under such officers' supervision
and (ii) to the best of such officers' knowledge, based on such review, the
Master Servicer has fulfilled all of its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the
nature and status thereof. Copies of any such statement shall be provided by the
Trustee to any Certificateholder and to any Person identified to the Trustee as
a prospective transferee of a Certificate, upon 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 90 days following the end of each fiscal year of the
Master Servicer, commencing in 2001, 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 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.





                                       76
<PAGE>

         (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,
access to the documentation regarding the Mortgage Loans required by applicable
laws and regulations. Such access shall be afforded without charge, but only
upon reasonable request and during normal business hours at the offices of the
Master Servicer designated by it. In addition, access to the documentation
regarding the Mortgage Loans will be provided to any Certificateholder, the
Trustee 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) Within 15 days after each Distribution Date, the Trustee shall file
with the Securities and Exchange Commission via the Electronic Data Gathering
and Retrieval System (EDGAR), a Form 8-K with a copy of the statement to
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2001, the Trustee shall file a Form 15 Suspension Notification with
respect to the Trust Fund, if applicable. Prior to March 30, 2001, the Trustee
shall file a Form 10-K, in substance conforming to industry standards, with
respect to the Trust Fund. The Depositor hereby grants to the Trustee a limited
power of attorney to execute 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 Fund. The Depositor agrees to
promptly furnish to the Trustee, from time to time upon request, such further
information, reports and financial statements within its control related to this
Agreement and the Mortgage Loans as the Trustee reasonably deems appropriate to
prepare and file all necessary reports with the Securities and Exchange
Commission. The Trustee shall have no responsibility to file any items with the
Securities and Exchange Commission other than those specified in this Section.

         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 either sell
any REO Property by 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 an Opinion of Counsel, addressed to
the Trustee 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 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.




                                       77
<PAGE>

         (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 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;

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





                                       78
<PAGE>

              (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, 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 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 at such price and
upon such terms and conditions as the Master Servicer shall deem necessary or
advisable, 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 3:00 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 received in the related Due Period. The Master Servicer
shall not have the right to reimbursement for any amounts remitted to the
Trustee in respect of Compensating Interest. Such amounts so remitted shall be
included in the Available Funds and distributed therewith on the next
Distribution Date. The Master Servicer shall not be obligated to pay
Compensating Interest with respect to Relief Act Interest Shortfalls.

         Section 3.25.     [Reserved].

         Section 3.26.     OBLIGATIONS OF THE MASTER SERVICER IN RESPECT OF
                           MORTGAGE RATES AND MONTHLY PAYMENTS.




                                       80
<PAGE>

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

         Section 3.28.     RESERVE FUND.

         No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, segregated trust account titled, "Reserve Fund,
Wells Fargo Bank Minnesota, N.A., as Trustee, in trust for registered Holders of
Option One Mortgage Loan Trust 2000-4, Asset-Backed Certificates, Series
2000-4." On the Closing Date, the Depositor will deposit, or cause to be
deposited, into the Reserve Fund $1,000.

         On each Distribution Date as to which there is a Net WAC Rate Carryover
Amount payable to the Class A Certificates or the Mezzanine Certificates, the
Trustee has been directed by the Class C Certificateholders to, and therefore
will, deposit into the Reserve Fund the amounts described in Section
4.01(d)(viii), 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




                                       81
<PAGE>

of the Class A Certificates and the Mezzanine Certificates, and will distribute
such amounts to the Holders of the Class A Certificates and the Mezzanine
Certificates in the amounts and priorities set forth in Section 4.01(d). If no
Net WAC Rate Carryover Amounts are payable on a Distribution Date, the Trustee
shall deposit into the Reserve Fund 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 Reserve
Fund, 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 Reserve Fund and all
amounts deposited into the Reserve Fund (other than the initial deposit therein
of $1,000) shall be treated as amounts distributed by REMIC 3 to the Holders 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 Reserve Fund will be released by the Trust and
distributed to the Class C Certificateholders or their designees. The Reserve
Fund 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 Reserve Fund 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 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 Reserve Fund 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 Reserve Fund 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 Reserve Fund in respect of any Net Wac Rate Carryover Amount
shall be assigned a value of zero.

         Section 3.29.     ADVANCE FACILITY.





                                       82
<PAGE>

         (a) The Trustee on behalf of the Trust Fund, with the consent of the
Master Servicer, is hereby authorized to enter into a facility with any Person
which provides that such Person (an "Advancing Servicer") may make all or a
portion of the 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. To the
extent that an Advancing Servicer makes all or a portion of any Advance or any
Servicing Advance and provides the Trustee with notice acknowledged by the
Servicer that such Advancing Servicer is entitled to reimbursement, such
Advancing Servicer 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 Servicer must specify the amount of the reimbursement and
must specify which Section of this Agreement permits the applicable Advance or
Servicing Advance to be reimbursed.
The Trustee shall be entitled to rely without independent investigation on the
Advancing Servicer's statement with respect to the amount of any reimbursement
pursuant to this Section 3.29 and with respect to the Advancing Servicer's
statement with respect to the Section of this Agreement permits the applicable
Advance or Servicing Advance to be reimbursed. An Advancing Servicer whose
obligations are limited to the making of Advances and/or Servicing Advances
shall not be required to meet the qualifications of a Master Servicer or a
Sub-Servicer pursuant to Section 6.06 hereof and will not be deemed to be a
Sub-Servicer under this Agreement.

         (b) If an advancing facility is entered into, then the Master Servicer
shall not be permitted to reimburse itself therefor under Section 3.11(ii),
Section 3.11(iii), Section 3.11(v), Section 3.11(vi) Section 3.11(vii) 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 Servicer, 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(ii), Section 3.11(iii), Section
3.11(v), Section 3.11(vi), Section 3.11(vii) 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 Servicer 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.

         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




                                       83

deposited by the Master Servicer, no later than two Business Days following
receipt thereof, into the Collection Account.

              (ix) to the PMI Insurer, any payments made under the PMI Policy,
         to the extent such payments were the result of incorrect data supplied
         to the PMI Insurer by the Originator;

              (x) to the Holders of the Class C Certificates, the Monthly
         Interest Distributable Amount for such Class and any remaining
         Overcollateralization Release Amount for such Distribution Date;

              (xi) if such Distribution Date follows the Prepayment Period
         during which occurs the latest date on which a Prepayment Charge may be
         required to be paid in respect of any Mortgage Loans, to the Holders of
         the Class P Certificates, in reduction of the Certificate Principal
         Balance thereof, until the Certificate Principal Balance thereof is
         reduced to zero; and

              (xii) any remaining amounts to the Holders of the Residual

Participants in accordance with its normal procedures. Each Depository
Participant shall be responsible for disbursing such distribution to the
Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. All such credits and disbursements
with




                                       87
<PAGE>

respect to a Book-Entry Certificate are to be made by the Depository and the
Depository Participants in accordance with the provisions of the Certificates.

have any responsibility therefor except as otherwise provided by applicable law.

or applicable portion thereof during which such Person was a Certificateholder.
Such obligation of the Trustee shall be deemed




                                       90

to have been satisfied to the extent that substantially comparable information

statement containing the information provided pursuant to the previous paragraph
aggregated for such calendar year or applicable portion thereof during which

         Section 4.04.     REMITTANCE REPORTS; ADVANCES.

         (a) On the second Business Day following each Determination Date but in
no event later than the 22nd day of each month (or if such 22nd day is not a
Business Day, the preceding Business Day), the Master Servicer shall deliver to
the Trustee 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 22nd day of each
month (or if such 22nd 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.

         (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 3:00 p.m. New York time on the Master Servicer Remittance
Date, the Master Servicer shall remit in immediately available funds to the
Trustee for deposit in the Distribution Account an amount equal to the aggregate
amount of Advances, if any, to be made in respect of the Mortgage Loans and REO
Properties for the related Distribution Date either (i) from its own funds or
(ii) from the Collection Account, to the extent of funds held therein for future
distribution (in which case it will cause to be made an appropriate entry in the
records of Collection Account that amounts held for future distribution have
been, as permitted by this Section 4.04, 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 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 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 Depositor and the
Trustee.

         Section 4.05.     PRE-FUNDING ACCOUNT.

              (a) No later than the Closing Date, the Trustee shall establish
and maintain a segregated trust account that is an Eligible Account, which shall
be titled "Pre-Funding Account, Wells Fargo Bank Minnesota, N.A., as trustee for
the registered holders of Option One Mortgage Loan Trust 2000-4, Asset-Backed
Certificates, Series 2000-4" (the "Pre-Funding Account"). The Trustee shall,
promptly upon receipt, deposit in the Pre-Funding Account and retain therein the
Original Pre- Funded Amount remitted on the Closing Date to the Trustee by the
Depositor. Funds deposited in




                                       92
<PAGE>

the Pre-Funding Account 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
Account 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 Account and shall
report all items of income, deduction, gain or loss arising therefrom. All
income and gain realized from investment of funds deposited in the Pre-Funding
Account shall be for the sole and exclusive benefit of the Master Servicer and
shall be remitted by the Trustee to the Master Servicer no later than the first
Business Day following receipt of such income and gain by the Trustee. The
Master Servicer shall deposit in the Pre-Funding Account the amount of any net
loss incurred in respect of any such Permitted Investment immediately upon
realization of such loss without any right of reimbursement therefor. At no time
will the Pre-Funding Account be an asset of any REMIC created hereunder.

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

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

              (ii) If the amount on deposit in the Pre-Funding Account
         (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 Account (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 Account or deposited therein in error; and

              (iv) To clear and terminate the Pre-Funding Account 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.

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

         Section 4.06.     INTEREST COVERAGE ACCOUNT.

              (a) No later than the Closing Date, the Trustee shall establish
and maintain a segregated trust account that is an Eligible Account, which shall
be titled "Interest Coverage Account, Wells Fargo Bank Minnesota, N.A., as
trustee for the registered holders of Option One Mortgage Loan Trust 2000-4,
Asset-Backed Certificates, Series 2000-4" (the "Interest Coverage Account"). The
Trustee shall, promptly upon receipt, deposit in the Interest Coverage Account
and retain therein the Interest Coverage Amount remitted on the Closing Date to
the Trustee by the Depositor. Funds deposited in the Interest Coverage Account
shall be held in trust by the Trustee for the Certificateholders for the uses
and purposes set forth herein.

              (b) For federal income tax purposes, the Master Servicer shall be
the owner of the Interest Coverage Account and shall report all items of income,
deduction, gain or loss arising therefrom.
At no time will the Interest Coverage Account be an asset of any REMIC created
hereunder. All income and gain realized from investment of funds deposited in
the Interest Coverage Account shall be for the sole and exclusive benefit of the
Master Servicer and shall be remitted by the Trustee to the Master Servicer no
later than the first Business Day following receipt of such income and gain by
the Trustee. The Master Servicer shall deposit in the Interest Coverage Account
the amount of any net loss incurred in respect of any such Permitted Investment
immediately upon realization of such loss.

              (c) On each Distribution Date during the Funding Period and on the
Distribution Date immediately following the end of the Funding Period, the
Trustee shall withdraw from the Interest Coverage Account and deposit in the
Distribution Account an amount equal to 30 days' interest on the excess, if any,
of the Original Pre-Funded Amount over the aggregate Principal Balance of
Subsequent Mortgage Loans that both (i) had a Due Date during the Due Period
relating to such Distribution Date and (ii) had a Subsequent Cut-off Date prior
to the first day of the month in which such Distribution Date occurs, at a per
annum rate equal to the Pass-Through Rate of the Class A Certificates and the
Mezzanine Certificates for such Distribution Date, with the Pass-Through Rate on
the Class A Certificates and the Mezzanine Certificates, solely for the purposes
of the foregoing calculation, each being multiplied by a fraction, the numerator
of which is the actual number of days in the Accrual Period for such Class for
such Distribution Date, and the denominator of which is 30. Such withdrawal and
deposit shall be treated as a contribution of cash by the Master Servicer to
REMIC 1 and REMIC 2 on the date thereof with REMIC 2 receiving that portion of
the contribution, if any, to the extent that the rate of LIBOR used to calculate
the Pass-Through Rate on the Class A Certificates and the Mezzanine Certificates
for such Distribution Date exceeds 6.62% per annum. Immediately following any
such withdrawal and deposit, and immediately following the conveyance of any
Subsequent Mortgage Loans to the Trust on any Subsequent Transfer Date, the
Trustee shall withdraw from the Interest Coverage Account and remit to the
Master Servicer or its designee an amount equal to the excess, if any, of the
amount remaining in such Interest Coverage Account over the amount that would be
required to be withdrawn therefrom (assuming sufficient funds therein) pursuant
to the preceding sentence on each subsequent Distribution Date, if any, that
will occur during the Funding Period or that will be the Distribution Date
immediately following the end of the Funding Period, if no Subsequent Mortgage
Loans were acquired by the Trust Fund after the end of the Prepayment Period
relating to the current Distribution Date (assuming that LIBOR remains




                                       94
<PAGE>

constant at the level of LIBOR applicable to the calculation of the Pass-Through
Rate for the Class A Certificates and the Mezzanine Certificates for the current
Distribution Date).

              (d) Upon the earliest of (i) the Distribution Date immediately
following the end of the Funding Period, (ii) the reduction of the Certificate
Principal Balances of the Certificates to zero or (iii) the termination of this
Agreement in accordance with Section 10.01, any amount remaining on deposit in
the Interest Coverage Account after distributions pursuant to paragraph (c)
above shall be withdrawn by the Trustee and paid to the Master Servicer or its
designee.

         Section 4.07.     DISTRIBUTIONS ON THE REMIC REGULAR INTERESTS.

         (a) On each Distribution Date, the Trustee shall cause in the following
order of priority, the following amounts to be distributed by REMIC 1 to REMIC 2
on account of the REMIC 1 Regular Interests or withdrawn from the Distribution
Account and distributed to the holders of the Class R Certificates (in respect
of the Class R-1 Interest), as the case may be:

              (i) first, to the extent of Available Funds, to Holders of REMIC 1
         Regular Interest LT1A, REMIC 1 Regular Interest LT1B, REMIC 1 Regular
         Interest LT1C, REMIC 1 Regular Interest LT1D, REMIC 1 Regular Interest
         LT1E, REMIC 1 Regular Interest LT1F and REMIC 1 Regular Interest LT1P,
         PRO RATA, in an amount equal to (A) the Uncertificated Accrued Interest
         for such Distribution Date, plus (B) any amounts in respect thereof
         remaining unpaid from previous Distribution Dates. Amounts payable as
         Uncertificated Accrued Interest in respect of REMIC 1 Regular Interest
         LT1F shall be reduced when the REMIC 1 Overcollateralized Amount is
         less than the REMIC 1 Target Overcollateralized Amount, by the lesser
         of (x) the amount of such difference and (y) the Maximum LT1F
         Uncertificated Accrued Interest Deferral Amount; and

              (ii) second, to the Holders of REMIC 1 Regular Interests, in an
         amount equal to the remainder of the Available Funds for such
         Distribution Date after the distributions made pursuant to clause (i)
         above, allocated as follows:

                  (a) to the Holders of REMIC 1 Regular Interest LT1A, 98.00% of
              such remainder, until the Uncertificated Principal Balance of such
              Uncertificated REMIC 1 Regular Interest is reduced to zero;

                  (b) to the Holders of REMIC 1 Regular Interest LT1B, REMIC 1
              Regular Interest LT1C, REMIC 1 Regular Interest LT1D and REMIC 1
              Regular Interest LT1E, 1.00% of such remainder, in the same
              proportion as principal payments are allocated to the
              Corresponding Certificates, until the Uncertificated Principal
              Balances of such REMIC 1 Regular Interests are reduced to zero;

                  (c) to the Holders of REMIC 1 Regular Interest LT1F, 1.00% of
              such remainder, until the Uncertificated Principal Balance of such
              REMIC 1 Regular Interest is reduced to
              zero;





                                       95
<PAGE>

                  (d) to the Holders of REMIC 1 Regular Interest LT1P, on the
              Distribution Date immediately following the expiration of the
              latest Prepayment Charge as identified on the Prepayment Charge
              Schedule or any Distribution Date thereafter until $100 has been
              distributed pursuant to this clause; then

              (e) any remaining amount to the Holders of the Class R
         Certificates (in respect of the Class R-1 Interest);

provided, however, that 98.00% and 2.00% of any principal payments that are
attributable to an Overcollateralization Release Amount shall be allocated to
Holders of REMIC 1 Regular Interest LT1A and REMIC 1 Regular Interest LT1F,
respectively.

         Section 4.08.     ALLOCATION OF REALIZED LOSSES.

         (a) All Realized Losses on the Mortgage Loans allocated to any Regular
Certificate shall be allocated by the Trustee on each Distribution Date as
follows: first, to Net Monthly Excess Cashflow; second, to the Class C
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; third, to the Class M-3 Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; fourth, to the Class M-2 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero; and
fifth, to the Class M-1 Certificates, until the Certificate Principal Balance
thereof has been reduced to zero. All Realized Losses to be allocated to the
Certificate Principal Balances of all Classes on any Distribution Date shall be
so allocated after the actual distributions to be made on such date as provided
above. All references above to the Certificate Principal Balance of any Class of
Certificates shall be to the Certificate Principal Balance of such Class
immediately prior to the relevant Distribution Date, before reduction thereof by
any Realized Losses, in each case to be allocated to such Class of Certificates,
on such Distribution Date.

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

         (b) All Realized Losses on the Mortgage Loans shall be deemed to have
been allocated in the specified percentages, as follows: first, to
Uncertificated Accrued Interest payable to the REMIC 1 Regular Interest LT1A and
REMIC 1 Regular Interest LT1F up to an aggregate amount equal to the REMIC 1
Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the
Uncertificated Principal Balances of REMIC 1 Regular Interest LT1A and REMIC 1
Regular Interest LT1F up to an aggregate amount equal to the REMIC 1 Principal
Loss Allocation Amount, 98% and 1%, respectively; third, to the Uncertificated
Principal Balances of REMIC 1 Regular Interest LT1A, REMIC 1 Regular Interest
LT1E and REMIC 1 Regular Interest LT1F, 98%, 1% and 1%, respectively, until the

reduced to zero; fourth, to the Uncertificated Principal Balances of REMIC 1
Regular Interest LT1A, REMIC 1 Regular Interest LT1D and REMIC 1 Regular

Balance of REMIC 1 Regular Interest LT1D has been




                                       96

reduced to zero; and fifth, to the Uncertificated Principal Balances of REMIC 1
Regular Interest LT1A, REMIC 1 Regular Interest LT1C and REMIC 1 Regular
Interest LT1F, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC 1 Regular Interest LT1C has been reduced to zero.

                                THE CERTIFICATES

         Section 5.01.     THE CERTIFICATES.

         Each of the Class A Certificates, the Mezzanine Certificates, the Class
P Certificates, the Class C Certificates and the Class R Certificates shall be
substantially in the forms annexed hereto as exhibits, and shall, on original
issue, be executed, authenticated and delivered by the Trustee to or upon the
order of the Depositor concurrently with the sale and assignment to the Trustee
of the Trust Fund. The Class A Certificates and the Mezzanine Certificates shall
be initially evidenced by one or more Certificates representing a Percentage
Interest with a minimum dollar denomination of $50,000 and integral dollar
multiples of $1.00 in excess thereof, except that one Certificate of each such
Class of Certificates may be in a different denomination so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Certificate Principal Balance of such Class on the Closing Date. The Class P
Certificates, the Class C Certificates and the Class R Certificates are issuable
in any Percentage Interests; PROVIDED, HOWEVER, that the sum of all such
percentages for each such Class totals 100% and no more than ten Certificates of
each Class may be issued.

         The Certificates shall be executed on behalf of the Trust by manual or
facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the 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 Class A Certificates
and the Mezzanine 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




                                       98
<PAGE>

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.

         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 and the Class R-2 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.




                                       99
<PAGE>

         (c) If (i)(x) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and (y) the Trustee or the Depositor is
unable to locate a qualified successor, (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 Mezzanine Certificate, Class C Certificate, Class P
Certificate or Class R 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")
unless the Depositor, the Trustee




                                      100
<PAGE>

and the Master Servicer are provided with an Opinion of Counsel which
establishes to the satisfaction of the Depositor, the Trustee and the Master
Servicer that the purchase of such Certificates is permissible under applicable
law, will not constitute or result in any prohibited transaction under ERISA or
Section 4975 of the Code and will not subject the Depositor, the Master
Servicer, the 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. In the case of the Mezzanine Certificates, in lieu of such
Opinion of Counsel, any prospective transferee of such Certificates may provide
a certification (which in the case of the Mezzanine Certificates sold in
book-entry form, the Transferee will be deemed to have represented such
certification) in the form of Exhibit I to this Agreement (or other form
acceptable to the Depositor, the Trustee and the Master Servicer), which the
Trustee may rely upon without further inquiry or investigation. Neither an
Opinion of Counsel nor any certification will be required in connection with the
initial transfer of any such Certificate by the Depositor to an affiliate of the
Depositor (in which case, the Depositor or any affiliate thereof shall have
deemed to have represented that such affiliate is not a Plan or a Person
investing Plan Assets) and the Trustee shall be entitled to conclusively rely
upon a representation (which, upon the request of the Trustee, shall be a
written representation) from the Depositor of the status of such transferee as
an affiliate of the Depositor.

         The provisions contained in the immediately preceding paragraph shall
no longer apply to the Mezzanine Certificates upon delivery by the Depositor
(which the Depositor shall timely deliver) to the Trustee of an Officers'
Certificate stating (following such time that such statement becomes accurate)
that the amendments proposed by the United States Department of Labor (the
"DOL") to be made to Prohibited Transaction Exemption 90-59, 55 Fed. Reg. 36724
(September 6, 1990), as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997)
and similar exemptions have been published in final form substantially as
proposed in the DOL Exemption Application No. D-10809, 65 Fed. Reg. 51454
(August 23, 2000). If such Officers' Certificate is delivered to the Trustee,
the Trustee, the Depositor and the Master Servicer are authorized to take any
action reasonably necessary to give effect thereto.

         If any Class C Certificate, Class P Certificate or Class R Certificate
or any interest therein is acquired or held in violation of the provisions of
the preceding paragraph, the next preceding permitted beneficial owner will be
treated as the beneficial owner of that Certificate retroactive to the date of
transfer to the purported beneficial owner. Any purported beneficial owner whose
acquisition or holding of any such Certificate or interest therein was effected
in violation of the provisions of the preceding paragraph shall indemnify and
hold harmless the Depositor, the Master Servicer, the Trustee 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 Class R
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




                                      101
<PAGE>

the rights of each Person acquiring any Ownership Interest in a Class R
Certificate are expressly subject to the following provisions:

              (i) Each Person holding or acquiring any Ownership Interest in a
         Class R 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 Class R
         Certificate unless such Ownership Interest is a PRO RATA undivided
         interest.

              (iii) In connection with any proposed transfer of any Ownership
         Interest in a Class R 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 Class R 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 Class R Certificates.

              (iv) Any attempted or purported transfer of any Ownership Interest
         in a Class R 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 Class R
         Certificate, then the prior Holder of such Class R Certificate that is
         a Permitted Transferee shall, upon discovery that the registration of
         transfer of such Class R 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 Class R Certificate. The
         Trustee shall be under no liability to any Person for any registration
         of transfer of a Class R Certificate that is in fact not permitted by
         this Section or for making any distributions due on such Class R
         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 Class R
         Certificate that was in fact not a Permitted Transferee at the time
         such distributions were made all distributions made on such Class R
         Certificate. Any such distributions so recovered by the Trustee shall
         be distributed and delivered by the Trustee to the prior Holder of such
         Class R Certificate that is a Permitted Transferee.

              (v) 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 shall have the right but
         not the obligation, without notice to the Holder of such Class R
         Certificate or any other Person having an Ownership Interest therein,
         to notify the Depositor to arrange for the sale of such Class R
         Certificate. The proceeds of such sale, net of commissions




                                      102
<PAGE>

         (which may include commissions payable to the Depositor or its
         affiliates in connection with such sale), expenses and taxes due, if
         any, will be remitted by the Trustee to the previous Holder of such
         Class R Certificate that is a Permitted Transferee, except that in the
         event that the Trustee determines that the Holder of such Class R
         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 Class R
         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, in form and substance satisfactory to the Trustee, (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 cancelled 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 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 constitute complete and indefeasible




                                      103
<PAGE>

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 Certificate
Registrar, any Paying Agent and any agent of the Master Servicer, the Depositor,
the Trustee, 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.

         (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.

                      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 nor any of the directors or officers or
employees or agents of the Master Servicer 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 in good faith pursuant to this
Agreement, or for errors in judgment; PROVIDED, HOWEVER, that this provision
shall not protect the Master Servicer 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 by reason
of its reckless disregard of its obligations and duties of the Master Servicer
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 any
director or officer or employee or agent of the Master Servicer 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 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




                                      105
<PAGE>

Master Servicer 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.

         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 in writing and such proposed
successor servicer is reasonably acceptable to the Trustee and (b) each Rating
Agency shall have delivered a letter to the Trustee prior to the appointment of
the successor servicer stating that the proposed appointment of such successor
servicer as Master 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 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.
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.

         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,




                                      106
<PAGE>

no such delegation is permitted that results in the delegee subservicing any
Mortgage Loans. The Master Servicer shall provide the Trustee 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, upon reasonable 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 its most recent publicly available financial statements
and such other information relating to its capacity to perform its obligations
under this Agreement.

         by a Servicing Officer of the Master Servicer; or

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

              (iv) The Master Servicer shall voluntarily go into liquidation,
         consent to the appointment of a conservator or receiver or liquidator
         or similar person in any insolvency, readjustment of debt, marshalling
         of assets and liabilities or similar proceedings of or relating to the

         (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 not
made by 5:00 P.M., New York time, on the Business Day immediately following the
Master Servicer Remittance Date (provided the Trustee shall give the Master
Servicer notice of such failure to advance by 5:00 P.M. New York time on the
Master Servicer Remittance Date), the Trustee shall 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 and (y) in the case of (i)(B), (ii), (iii), (iv)
and (v) above, the Trustee shall, at the direction of the Holders of each Class
of Regular Certificates evidencing Percentage Interests aggregating not less
than 51%, by notice then given in writing to the Master Servicer (and to the
Trustee if given by Holders of Certificates), terminate all of the rights and
obligations of the Master Servicer as servicer under this Agreement. Any such
notice to the Master Servicer shall also 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 applicable successor Master Servicer) for the administration
by it of all cash amounts that shall at the time be held by the Master Servicer
and to be deposited by it in the Collection Account, the Distribution Account,
any REO 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.

         Section 7.02.     TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

         (a) Within 90 days of 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




                                      109
<PAGE>

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. 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 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 pursuant to Section
3.06), 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 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, 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. 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.

         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 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 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.

         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 Majority Certificateholders
         relating to the time, method and place of conducting any proceeding for




                                      112
<PAGE>

         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 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.

         Section 8.02.     CERTAIN MATTERS AFFECTING THE TRUSTEE.

         (a)  Except as otherwise provided in Section 8.01:

              (i) the Trustee may request and rely upon, and shall be protected
         in acting or refraining from acting upon, any resolution, Officers'
         Certificate, certificate of auditors or any other certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, appraisal, bond or other paper or document reasonably believed
         by it to be genuine and to have been signed or presented by the proper
         party or parties, 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,
         pursuant to the provisions of this Agreement, unless such
         Certificateholders shall have offered to the Trustee reasonable
         security or indemnity against the costs, expenses and liabilities which
         may be incurred therein or thereby; the right of the Trustee to perform
         any discretionary act enumerated in this Agreement shall not be
         construed as a duty, and the Trustee shall not be answerable for other
         than its negligence or willful misconduct in the performance of any
         such act;





                                      113
<PAGE>

              (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 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, if paid
         by the Trustee, shall be reimbursed by the Master Servicer upon demand
         and, if not reimbursed by the Master Servicer, 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 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,




                                      114

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.

         The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself the Trustee Fee and, to the extent that the
funds therein are at anytime insufficient for such purpose, the Master Servicer
shall pay such fees. The Master Servicer (or the Depositor, if the Trustee
becomes the Master Servicer) will pay or reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Agreement (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all persons not regularly in its employ and any amounts paid by the
Trustee for the recording of Assignments of Mortgage pursuant to Section 2.01)
except 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 Master Servicer (or the Depositor, if
the Trustee becomes the Master Servicer) covenants and agrees to indemnify the
Trustee and its officers, directors, employees and agents from, and hold it
harmless against, any and all losses, liabilities, damages, claims or expenses
incurred in connection with any




                                      115
<PAGE>

legal action relating to this Agreement or the Certificates, other than 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.
This section shall survive termination of this Agreement or the resignation or
removal of any Trustee hereunder. If the Master Servicer (or the Depositor, if
the Trustee becomes the Master Servicer) defaults in its obligations to pay or
reimburse the Trustee any amount as required under this Section 8.05, the
Trustee shall be entitled to be paid or reimbursed such amount at any time from
the assets of the Trust Fund consisting of any amounts on deposit at such time
in the Collection Account or the Distribution Account.

         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 subject to supervision
or examination by federal or state authority. If such entity publishes reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 8.06, the combined capital and surplus of such entity shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. The principal office of the Trustee (other than the
initial Trustee) shall be in a state with respect to which an Opinion of Counsel
has been delivered to such Trustee at the time such Trustee is appointed Trustee
to the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 8.06, the Trustee shall resign immediately
in the manner and with the effect specified in Section 8.07.

         Section 8.07.     RESIGNATION OR REMOVAL OF TRUSTEE.

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

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Depositor or if at any time the Trustee shall be legally
unable to act, or shall be adjudged a bankrupt or insolvent, or a receiver of
the Trustee or of 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 or
the Master Servicer may remove the Trustee. If the Depositor or the Master
Servicer removes the Trustee under the authority of the immediately preceding
sentence, the Depositor shall promptly appoint a successor Trustee by written
instrument, in duplicate, one




                                      116
<PAGE>

copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor trustee.

         The Majority Certificateholders may at any time remove the Trustee by
written instrument or instruments delivered to the Master Servicer, the
Depositor and the Trustee; the Depositor shall thereupon use its best efforts to
appoint a successor trustee in accordance with this Section.

         Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

         Section 8.08.     SUCCESSOR TRUSTEE.

         Any successor Trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor, the 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 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




                                      117
<PAGE>

Property may at the time be located, the Depositor and the Trustee acting
jointly shall have the power and shall execute and deliver all instruments to
appoint one or more Persons approved by the Trustee to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust, and to vest in such Person or Persons, in such
capacity and for the benefit of the Certificateholders, such title to the Trust,
or any part thereof, and, subject to the other provisions of this Section 8.10,
such powers, duties, obligations, rights and trusts as the 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. If the
Master Servicer shall not have joined in such appointment within 15 days after
the receipt by it of a request so to do, or in the case a 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:

              (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, 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




                                      118
<PAGE>

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 and the Master Servicer.

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

         Section 8.11.     LIMITATION OF LIABILITY.

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

         Section 8.12.     TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
                           CERTIFICATES.

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




                                      119
<PAGE>

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

         Section 8.14.     WAIVER OF BOND REQUIREMENT.

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

         Section 8.15.     WAIVER OF INVENTORY, ACCOUNTING AND APPRAISAL
                           REQUIREMENT.

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

                                   ARTICLE IX

                              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.

         (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




                                      121
<PAGE>

to be taken) any action that, under the REMIC Provisions, if taken or not taken,
as the case may be, could (i) endanger the status of such REMIC as a REMIC or
(ii) result in the imposition of a tax upon such REMIC (including but not
limited to the tax on prohibited transactions as defined in Code Section
860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d)
of the Code) (either such event, an "Adverse REMIC Event") unless the Trustee
and the 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 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 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.

         (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.

         (k) On or before April 15 of each calendar year beginning in 2001, the
Master Servicer shall deliver to the Trustee and each Rating Agency an Officers'
Certificate stating the Master Servicer's compliance with the provisions of this
Section 9.01.

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

         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




                                      122
<PAGE>

pursuant to Article X of this Agreement, (iv) a substitution pursuant to Article
II of this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article
II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose
of any investments in the Distribution Account for gain, nor accept any
contributions to either REMIC after the Closing Date, unless it has received an
Opinion of Counsel (at the expense of the party causing such sale, disposition,
or substitution) that such disposition, acquisition, substitution, or acceptance
will not (a) affect adversely the status of any REMIC created hereunder as a
REMIC or of the interests therein other than the Residual Certificates as the
regular interests therein, (b) affect the distribution of interest or principal
on the Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
or (d) cause any REMIC created hereunder to be subject to a tax on prohibited
transactions or prohibited contributions pursuant to the REMIC Provisions.

         Section 9.03.     INDEMNIFICATION WITH RESPECT TO CERTAIN TAXES AND
                           LOSS OF REMIC STATUS.

         (a) In the event that any Trust 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
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).

         (b) In the event that any Trust 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 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

                                   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 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 may, at its option, terminate this Agreement on any
date on which the aggregate of the Principal Balances of the Mortgage Loans 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 plus the Original
Pre-Funded Amount, by purchasing, on the next succeeding Distribution Date, all
of the outstanding Mortgage Loans and REO Properties at a price equal to the
greater of the Stated Principal Balance of the Mortgage Loans and REO Properties
or the market value of the Mortgage Loans and REO Properties, in each case 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 and any accrued and unpaid
Net WAC Rate Carryover Amount (the "Termination Price").

         In connection with any such purchase pursuant to the preceding
paragraph, the Master Servicer 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,
by letter to the Certificateholders 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




                                      125
<PAGE>

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 the Master Servicer (if the Master
Servicer has exercised its right to purchase the Mortgage Loans) or the Trustee
(in any other case) shall give a second written notice to the remaining
Certificateholders, to surrender their Certificates for cancellation and receive
the final distribution with respect thereto. If within nine months 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 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 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
         for cash pursuant to the terms of the plan of complete liquidation.




                                      126
<PAGE>

         (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; 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 or (iii) to make any other provisions with respect to matters
or questions arising under this Agreement which shall not be inconsistent with
the provisions of this Agreement; PROVIDED, HOWEVER, that any such action listed
in clause (i) through (iii) above shall be deemed not to adversely affect in any
respect the interests of any Certificateholder, if evidenced by (i) 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 or (ii) an Opinion of Counsel delivered to the Master Servicer and
the Trustee.

         In addition, this Agreement may be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the Majority
Certificateholders for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Holders of Certificates; PROVIDED,
HOWEVER, that no such amendment or waiver shall (x) reduce in any manner the
amount of, or delay the timing of, payments on the Certificates or distributions
which are required to be made on any Certificate without the consent of the
Holder of such Certificate, (y) adversely affect in any material respect the
interests of the Holders of any Class of Certificates in a manner other than as
described in clause (x) above, without the consent of the Holders of
Certificates of such Class evidencing at least a 66% Percentage Interest in such
Class, or (z) reduce the percentage of Voting Rights required by clause (y)
above without the consent of the Holders of all Certificates of such Class then
outstanding. Upon approval of an amendment, a copy of such amendment shall be
sent to the Rating Agencies.

         Notwithstanding any provision of this Agreement to the contrary, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, delivered by (and at the expense of)
the Person seeking such Amendment, to the effect that such amendment will not
result in the imposition of a tax on any REMIC created hereunder constituting
part of the Trust Fund pursuant to the REMIC Provisions 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 and each Rating Agency.





                                      128
<PAGE>

         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 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




                                      129
<PAGE>

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.

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.

     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

Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the

the applicable Record Date in an amount equal to the product of the Percentage

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

     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

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

     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.

Depositor or the Trustee may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Depositor, the
Trustee nor any such agent shall be affected by any 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 Amount, 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

            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

     This certifies that Option One Mortgage Securities Corp. is the registered

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

Pooling and Servicing Agreement dated as of October 1, 2000 (the "Agreement")
among the Depositor, Option One Mortgage Corporation, as master servicer (the
"Master Servicer"), and Wells Fargo Bank Minnesota, N.A., a national banking

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

of 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, the Master Servicer 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.

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

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

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.

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

     This 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 Securities Corp. is the registered
owner of the Percentage Interest evidenced by this Certificate specified above
in the interest represented by all Certificates of the Class to which this
Certificate belongs in a Trust consisting primarily of the Mortgage Loans
deposited by Option One Mortgage Acceptance Corporation (the "Depositor"). The

October 1, 2000 (the "Agreement") among the Depositor, Option One Mortgage
Corporation, as master servicer (the "Master Servicer") and Wells Fargo Bank
Minnesota, N.A., 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 Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

     This Certificate does not have a principal balance or pass-through rate and
will be entitled to distributions only to the extent set forth in the Agreement.
In addition, any distribution of the proceeds of any remaining assets of the
Trust will be made only upon presentment and surrender of this Certificate at
the Corporate Trust Office or the office or agency maintained by the Trustee in
Minneapolis, Minnesota.

     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
of 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, the Master Servicer 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.

     No transfer of this Certificate to a Plan subject to ERISA or Section 4975
of the Code, any Person acting, directly or indirectly, on behalf of any such
Plan or any person using Plan Assets to acquire this Certificate shall be made
except in accordance with Section 5.02(d) of the Agreement.

     Each Holder of this Certificate will be deemed to have agreed to be bound
by the restrictions of the Agreement, including but not limited to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Certificate must be a Permitted Transferee, (ii) no Ownership Interest in
this Certificate may be transferred without delivery to the Trustee of (a) a
transfer affidavit of the proposed transferee and (b) a transfer certificate of
the transferor, each of such documents to be in the form described in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate to the Trustee as required pursuant to the Agreement, (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to transfer an Ownership Interest in this Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee. Pursuant to the Agreement, The Trustee will
provide the Internal Revenue Service and any pertinent persons with the
information needed to compute the tax imposed under the applicable tax laws on
transfers of residual interests to disqualified organizations, if any person
other than a Permitted Transferee acquires an Ownership Interest on a Class R
Certificate in violation of the restrictions mentioned above.

     Reference is hereby made to the further provisions of this 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 Certificate shall not be entitled to any benefit under the Agreement
or be valid for any purpose unless manually countersigned by an authorized
officer of the Trustee.

the Purchaser, on or before the Closing Date, the following documents or

which case the Trustee shall cause the endorsement to be completed or (B) in the
following form: "Pay to the order of Wells Fargo Bank Minnesota, N.A., as
Trustee, without recourse", or with respect to any lost Mortgage Note, an
original Lost Note Affidavit stating that the original mortgage note was lost,

               (ii) the original Mortgage with evidence of recording thereon,

otherwise available, a copy of such Mortgage or power of attorney, as the case
may be, certified to be a true and complete copy of the original submitted for
recording;

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

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

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

     The Seller hereby confirms to the Purchaser and the Trustee that it has
made the appropriate entries in its general accounting records to indicate that
such Mortgage Loans have been transferred to the Trustee and constitute part of
the Trust in accordance with the terms of the Pooling and Servicing Agreement.

     If any of the documents referred to in Section 2.02(ii), (iii) or (iv)
above has as of the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) been submitted for recording but either (x) has not
been returned from the applicable public recording office or (y) has been lost
or such public recording office has retained the original of such document, the
obligations of the Seller to deliver such documents shall be deemed to be
satisfied upon (1) delivery to the Trustee or the Custodian no later than the
Closing Date (or Subsequent Closing Date, with respect to Subsequent Mortgage
Loans), of a copy of each such document certified by the Seller in the case of
(x) above or the applicable public recording office in the case of (y) above to
be a true and complete copy of the original that was submitted for recording and
(2) if such copy is certified by


                                        3

<PAGE>



the Seller, delivery to the Trustee or the Custodian, promptly upon receipt
thereof of either the original or a copy of such document certified by the
applicable public recording office to be a true and complete copy of the
original. If the original lender's title insurance policy, or a certified copy
thereof, was not delivered pursuant to Section 2.02(v) above, the Seller shall
deliver or cause to be delivered to the Trustee or the Custodian, the original
or a copy of a written commitment or interim binder or preliminary report of
title issued by the title insurance or escrow company, with the original or a
certified copy thereof to be delivered to the Trustee or the Custodian, promptly
upon receipt thereof. The Seller shall deliver or cause to be delivered to the
Trustee or the Custodian promptly upon receipt thereof any other documents
constituting a part of a Mortgage File received with respect to any Mortgage
Loan, including, but not limited to, any original documents evidencing an
assumption or modification of any Mortgage Loan.

     Upon discovery or receipt of notice of any materially defective document
in, or that a document is missing from, a Mortgage File, the Seller shall have
90 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
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 Seller shall cause the Assignments which were delivered in blank and
cause 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; PROVIDED, HOWEVER, the Seller need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Seller to the
Trustee and the Rating Agencies, the recordation of such assignment is not
necessary to protect the Trustee's interest in the related Mortgage Loan;
PROVIDED, HOWEVER, notwithstanding the delivery of any Opinion of Counsel, 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, (ii) the occurrence of a Master Servicer Event
of Termination, (iii) the occurrence of a bankruptcy, insolvency or foreclosure
relating to the Seller, (iv) the occurrence of a servicing transfer as described
in Section 7.02 of the Pooling and Servicing Agreement or (iv) 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. 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


                                        4

<PAGE>



be reimbursed for such expenses by the Trust. The Seller shall be required to
deliver such assignments for recording within 30 days of the Closing Date (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans). 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 (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans), promptly
following the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) the Seller shall cause to be completed such
endorsements "Pay to the order of Wells Fargo Bank Minnesota, N.A., 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 270 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 270 day period, the Seller shall deliver to the
Purchaser, within such 270 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.

     Section 2.03 PAYMENT OF PURCHASE PRICE FOR THE MORTGAGE LOANS.

     In consideration of the sale of the Mortgage Loans from the Seller to the
Purchaser on the Closing Date, the Purchaser agrees to pay to the Seller on the

the Class M-1 Certificates, the Class M-2 Certificates and the Class M-3

incurred by the Purchaser in connection with the issuance of the Certificates,
including, without limitation, printing fees incurred in connection with the
prospectus relating to the Certificates, blue sky registration fees and
expenses, fees and expenses of Purchaser's counsel, fees of the rating agencies

                                  ARTICLE III.

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH


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

          (a) The Seller has good title to and is the sole owner and holder of
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.

          (d) The information set forth on Schedule I is true and correct in all
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 Seller and any affiliate of the Seller in compliance
with all applicable federal, state and local laws and regulations 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).

          (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.


                                        6

<PAGE>




          (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 September 2000 and with respect to
any Mortgage Loan that had a payment due on or before September 1, 2000, the
related Monthly Payment due on September 1, 2000 has been received. In addition,
none of the Mortgage Loans have been 30 or more days delinquent in the last 12
months and none 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
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 under the Mortgage Loan.

          (k) The Seller has not 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 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 condition exists which could give rise to any right of
rescission, set off, counterclaim, or defense including, without limitation, the
defense of usury, and no such right has been asserted.

          (n) To 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. Seller
is the sole insured of such mortgagee title insurance policy, and such mortgagee
title


                                        7

<PAGE>



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 Seller has no
knowledge of, any claims under such mortgagee title insurance policy. Seller is
not aware of any action by a prior holder and neither 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 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.

          (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


                                        8

<PAGE>



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

          (x) To 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.



                                        9

          (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.

          (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 approximately 6.13% 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 Seller, the Mortgagor, or anyone on behalf of the
Mortgagor; (ii) paid by any source other than the Mortgagor or (iii) 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


                                       10

<PAGE>



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.

          (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 approximately
36.14%; 7.24%; 7.17%; 6.47% and 5.41% of the Mortgage Loans, by Cut-off Date
Principal Balance will be secured by Mortgaged Properties located in California,
Florida, Maryland, New York and Massachusetts, respectively; and approximately
71.81% 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 3.55% 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 $261,236.

The Seller represents, warrants and covenants to the Purchaser as of the Closing
Date or as of such other date specifically provided herein or in the applicable
Assignment and Conveyance:

               (i) The Seller is duly organized, validly existing and in good
standing as a corporation under the laws of the State of California 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;

               (ii) 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
Seller, 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. At the time
of the sale of each Mortgage Loan by the Seller, the Seller had the full power
and authority to hold each Mortgage Loan and to sell each Mortgage Loan;

               (iii) 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 articles of incorporation or by-laws 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;

               (iv) 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;

               (v) The Seller 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 Seller unable to comply with HUD eligibility requirements or which would
require notification to HUD;

               (vi) The Seller 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 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


                                       12

<PAGE>



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 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 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;

               (ix) The consummation of the transactions contemplated by this
Agreement are in the ordinary course of business of the Seller. The sale of the
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
Subsections 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 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


                                       13

<PAGE>



paragraphs of this Section 3.04 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.

     Within 90 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 Subsection 3.02 or 3.03 and
such breach cannot be cured within 90 days of the earlier of either discovery by
or notice to the Seller of such breach, all of the Mortgage Loans shall, at the
Purchaser's option, be repurchased by the Seller at the Purchase Price. 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 3.04 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 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
Custodial 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


                                       14

<PAGE>



with respect to such Qualified Substitute Mortgage Loan or Loans as of the date
of substitution, the covenants, representations and warranties set forth in
Subsections 3.01, 3.02 or 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 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


                                       15

<PAGE>



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
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 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


                                       16

<PAGE>



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 Seller, if the indemnified
parties in this Article V consist of 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.

          (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


                                       17

<PAGE>



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 1933 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 1933 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 1933 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

     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

                  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

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

                                       19

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

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

     Section 7.07 INTENTION OF THE PARTIES. It is the intention of the parties
that the Purchaser is purchasing, and the Seller is selling, the Mortgage Loans
rather than 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 and the Trustee. The obligations of the Seller under this
Agreement cannot be assigned or delegated to a third party without the consent
of the Purchaser 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, 3.02 and 3.03 and the provisions of Article V hereof shall
survive the purchase of the Mortgage Loans hereunder.

Pooling and Servicing Agreement, are satisfied and (ii) each Subsequent Mortgage

Agreement substantially in the form of this Agreement.

     Section 2.02 OBLIGATIONS OF ORIGINATOR UPON SALE. In connection with any

such Mortgage Loan, as of the Cut-off Date, (i) its account number and (ii) the
Cut-off Date Principal Balance. Such file, which forms a part of Exhibit D to
the Pooling and Servicing Agreement, shall also be marked as Schedule I to this
Agreement and is hereby incorporated into and made a part of this Agreement.

          In connection with any conveyance by the Seller, the Seller shall on
behalf of the Purchaser deliver to, and deposit with the Trustee, as assignee of
the Purchaser, on or before the Closing Date, the following documents or
instruments with respect to each Mortgage Loan:

               (i) the original Mortgage Note, endorsed either (A) in blank, in
which case the Trustee shall cause the endorsement to be completed or (B) in the
following form: "Pay to the order of Wells Fargo Bank Minnesota, N.A., as
Trustee, without recourse", or with respect to any lost Mortgage Note, an
original Lost Note Affidavit stating that the original mortgage note was lost,
misplaced or destroyed, together with a copy of the related mortgage note;
PROVIDED, HOWEVER, that such substitutions of Lost Note Affidavits for original
Mortgage Notes may occur only with respect to Mortgage Loans, the aggregate
Cut-off Date Principal Balance of which is less than or equal to 1.00% of the
Pool Balance as of the Cut-off Date;

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

               (iii) an original Assignment of Mortgage, in form and substance
acceptable for recording. The Mortgage shall be assigned either (A) in blank,
without recourse or (B) to "Wells Fargo Bank Minnesota, N.A., as Trustee,

               (iv) an original copy of any intervening assignment of Mortgage

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

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

     The Originator hereby confirms to the Purchaser and the Trustee that it has
caused the appropriate entries to be made in the general accounting records of
the Seller, to indicate that such Mortgage Loans have been transferred to the
Trustee and constitute part of the Trust in accordance with the terms of the
Pooling and Servicing Agreement.

     If any of the documents referred to in Section 2.02(ii), (iii) or (iv)
above has as of the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) been submitted for recording but either (x) has not
been returned from the applicable public recording office or (y) has been lost
or such public recording office has retained the original of such document, the
obligations


                                        3

<PAGE>



of the Seller to deliver such documents shall be deemed to be satisfied upon (1)
delivery to the Trustee or the Custodian no later than the Closing Date (or
Subsequent Closing Date, with respect to Subsequent Mortgage Loans), of a copy
of each such document certified by the Originator in the case of (x) above or
the applicable public recording office in the case of (y) above to be a true and
complete copy of the original that was submitted for recording and (2) if such
copy is certified by the Originator, delivery to the Trustee or 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 insurance policy, or a
certified copy thereof, was not delivered pursuant to Section 2.02(v) above, the
Seller shall deliver or cause to be delivered to the Trustee or the Custodian,
the original or a copy of a written commitment or interim binder or preliminary
report of title issued by the title insurance or escrow company, with the
original or a certified copy thereof to be delivered to the Trustee or the
Custodian, promptly upon receipt thereof. The Originator and the Seller shall
deliver or cause to be delivered to the Trustee or the Custodian promptly upon
receipt thereof any other documents constituting a part of a Mortgage File
received with respect to any Mortgage Loan, including, but not limited to, any
original documents evidencing an assumption or modification of any Mortgage
Loan.

     Upon discovery or receipt of notice of any materially defective document
in, or that a document is missing from, a Mortgage File, the Seller shall have
90 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
and cause 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; PROVIDED, HOWEVER, the Originator need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Originator to
the Trustee and the Rating Agencies, the recordation of such assignment is not
necessary to protect the Trustee's interest in the related Mortgage Loan;
PROVIDED, HOWEVER, notwithstanding the delivery of any Opinion of Counsel, 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: (i) reasonable direction by Holders of Certificates entitled to at
least 25% of the Voting Rights, (ii) the occurrence of a Master Servicer Event
of Termination, (iii) the occurrence of a bankruptcy,


                                        4

<PAGE>



insolvency or foreclosure relating to the Originator, (iv) the occurrence of a
servicing transfer as described in Section 7.02 of the Pooling and Servicing
Agreement or (iv) 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. 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 be required to deliver such
assignments for recording within 30 days of the Closing Date (or Subsequent
Transfer Date, with respect to Subsequent Mortgage Loans). 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 (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans), promptly
following the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) the Originator shall cause to be completed such
endorsements "Pay to the order of Wells Fargo Bank Minnesota, N.A., 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 270 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 270 day period, the Originator shall deliver to the
Purchaser, within such 270 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

certified by an officer of the Originator to be a true and complete copy of the
original to the Purchaser.

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH


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

          (a) The Seller has good title to and is the sole owner and holder of
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.

          (d) The information set forth on Schedule I is true and correct in all
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 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).

          (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


                                        6

<PAGE>



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 September 2000 and with respect to
any Mortgage Loan that had a payment due on or before September 1, 2000, the
related Monthly Payment due on September 1, 2000 has been received. In addition,
none of the Mortgage Loans have been 30 or more days delinquent in the last 12
months and none 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 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 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 condition exists which could give rise to any right of
rescission, set off, counterclaim, or defense including, without limitation, the
defense of usury, and no such right has been asserted.

          (n) To 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


                                        7

<PAGE>



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.
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 Originator has no knowledge of, any claims under such mortgagee title
insurance policy. Originator is not aware of any action by a prior holder and
neither 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 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.

          (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


                                        8

<PAGE>



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 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.


                                        9

<PAGE>




          (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.

          (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 approximately 6.13% 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 Seller, the Mortgagor, or anyone on
behalf of the Mortgagor; (ii) paid by any source other than the Mortgagor or
(iii) 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.



                                       10

<PAGE>



          (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.

          (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 approximately
36.14%; 7.24%; 7.17%; 6.47% and 5.41% of the Mortgage Loans, by Cut-off Date
Principal Balance will be secured by Mortgaged Properties located in California,
Florida, Maryland, New York and Massachusetts, respectively; and approximately
71.81% 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 3.55% 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%.


                                       11

<PAGE>




          (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 $261,236.

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
Subsections 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 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.



                                       15

     Within 90 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 Subsection 3.02 or
3.03 and such breach cannot be cured within 90 days of the earlier of either
discovery by or notice to the Originator of such breach, all of the Mortgage
Loans shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price. 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
Custodial 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 Subsections 3.01, 3.02 or 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.


                                       16

<PAGE>



          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.

                                   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 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


                                       17

<PAGE>



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 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.

          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.


                                       18

<PAGE>



          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.

          (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%


                                       19

<PAGE>



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 1933 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 1933 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 1933
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 1933 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 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.

                            MISCELLANEOUS PROVISIONS


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

                  1100 North Market Street

                  Attention: Corporate Trust Administration

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

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

enforceability of the other provisions of this Agreement.


                                       21

<PAGE>




     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 and the Trustee. 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
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


                                       22

<PAGE>



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.

Agreement substantially in the form of this Agreement.

such Mortgage Loan, as of the Cut-off Date, (i) its account number and (ii) the
Cut-off Date Principal Balance. Such file, which forms a part of Exhibit D to
the Pooling and Servicing Agreement, shall also be marked as Schedule I to this
Agreement and is hereby incorporated into and made a part of this Agreement.

          In connection with any conveyance by the Seller, the Seller shall on
behalf of the Purchaser deliver to, and deposit with the Trustee, as assignee of
the Purchaser, on or before the Closing Date, the following documents or
instruments with respect to each Mortgage Loan:

               (i) the original Mortgage Note, endorsed either (A) in blank, in
which case the Trustee shall cause the endorsement to be completed or (B) in the
following form: "Pay to the order of Wells Fargo Bank Minnesota, N.A., as
Trustee, without recourse", or with respect to any lost Mortgage Note, an
original Lost Note Affidavit stating that the original mortgage note was lost,
misplaced or destroyed, together with a copy of the related mortgage note;
PROVIDED, HOWEVER, that such substitutions of Lost Note Affidavits for original
Mortgage Notes may occur only with respect to Mortgage Loans, the aggregate
Cut-off Date Principal Balance of which is less than or equal to 1.00% of the
Pool Balance as of the Cut-off Date;

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

               (iii) an original Assignment of Mortgage, in form and substance
acceptable for recording. The Mortgage shall be assigned either (A) in blank,
without recourse or (B) to "Wells Fargo Bank Minnesota, N.A., as Trustee,
without recourse";

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

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

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

     The Originator hereby confirms to the Purchaser and the Trustee that it has
caused the appropriate entries to be made in the general accounting records of
the Seller, to indicate that such Mortgage Loans have been transferred to the
Trustee and constitute part of the Trust in accordance with the terms of the
Pooling and Servicing Agreement.

     If any of the documents referred to in Section 2.02(ii), (iii) or (iv)
above has as of the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) been submitted for recording but either (x) has not
been returned from the applicable public recording office or (y) has been lost
or such public recording office has retained the original of such document, the
obligations


                                        3

<PAGE>



of the Seller to deliver such documents shall be deemed to be satisfied upon (1)
delivery to the Trustee or the Custodian no later than the Closing Date (or
Subsequent Closing Date, with respect to Subsequent Mortgage Loans), of a copy
of each such document certified by the Originator in the case of (x) above or
the applicable public recording office in the case of (y) above to be a true and
complete copy of the original that was submitted for recording and (2) if such
copy is certified by the Originator, delivery to the Trustee or 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 insurance policy, or a
certified copy thereof, was not delivered pursuant to Section 2.02(v) above, the
Seller shall deliver or cause to be delivered to the Trustee or the Custodian,
the original or a copy of a written commitment or interim binder or preliminary
report of title issued by the title insurance or escrow company, with the
original or a certified copy thereof to be delivered to the Trustee or the
Custodian, promptly upon receipt thereof. The Originator and the Seller shall
deliver or cause to be delivered to the Trustee or the Custodian promptly upon
receipt thereof any other documents constituting a part of a Mortgage File
received with respect to any Mortgage Loan, including, but not limited to, any
original documents evidencing an assumption or modification of any Mortgage
Loan.

     Upon discovery or receipt of notice of any materially defective document
in, or that a document is missing from, a Mortgage File, the Seller shall have
90 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
and cause 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; PROVIDED, HOWEVER, the Originator need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Originator to
the Trustee and the Rating Agencies, the recordation of such assignment is not
necessary to protect the Trustee's interest in the related Mortgage Loan;
PROVIDED, HOWEVER, notwithstanding the delivery of any Opinion of Counsel, 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: (i) reasonable direction by Holders of Certificates entitled to at
least 25% of the Voting Rights, (ii) the occurrence of a Master Servicer Event
of Termination, (iii) the occurrence of a bankruptcy,


                                        4

<PAGE>



insolvency or foreclosure relating to the Originator, (iv) the occurrence of a
servicing transfer as described in Section 7.02 of the Pooling and Servicing
Agreement or (iv) 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. 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 be required to deliver such
assignments for recording within 30 days of the Closing Date (or Subsequent
Transfer Date, with respect to Subsequent Mortgage Loans). 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 (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans), promptly
following the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans) the Originator shall cause to be completed such
endorsements "Pay to the order of Wells Fargo Bank Minnesota, N.A., 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 270 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 270 day period, the Originator shall deliver to the
Purchaser, within such 270 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
certified by an officer of the Originator to be a true and complete copy of the
original to the Purchaser.

     Section 2.03 PAYMENT OF PURCHASE PRICE FOR THE MORTGAGE LOANS.

     In consideration of the sale of the Mortgage Loans from the Seller to the
Purchaser on the Closing Date, the Purchaser agrees to pay to the Seller on the
Closing Date (the "Purchase Price") by transfer of (i) immediately available
funds in an amount equal to the net sale proceeds of the Class A Certificates,
the Class M-1 Certificates, the Class M-2 Certificates and the Class M-3
Certificates and (ii) the Class C Certificates, the Class P Certificates and the
Class R Certificates (collectively the "Option One Certificates") which Option

expenses incurred by the Purchaser in connection with the issuance of the
Certificates, including, without limitation, printing fees incurred in
connection with the prospectus relating to the Certificates, blue sky
registration fees and expenses, fees and expenses of Purchaser's counsel, fees
of the rating agencies requested to rate the Certificates, accountant's fees and
expenses and the fees and expenses of the Trustee and other out-of-pocket costs,
if any.

                                  ARTICLE III.

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH


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

          (a) The Seller has good title to and is the sole owner and holder of
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.

          (d) The information set forth on Schedule I is true and correct in all
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 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).

          (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


                                        6

<PAGE>



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 September 2000 and with respect to
any Mortgage Loan that had a payment due on or before September 1, 2000, the
related Monthly Payment due on September 1, 2000 has been received. In addition,
no more than 1.5% of the Mortgage Loans have been 30 or more days delinquent in
the last 12 months and none 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 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 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 condition exists which could give rise to any right of
rescission, set off, counterclaim, or defense including, without limitation, the
defense of usury, and no such right has been asserted.

          (n) To 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


                                        7

<PAGE>



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. 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 Originator has no knowledge of, any claims under such
mortgagee title insurance policy. Originator is not aware of any action by a
prior holder and neither 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 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.

          (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


                                        8

<PAGE>



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 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


                                        9

<PAGE>



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.

          (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 approximately 6.13% 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 Seller, the Mortgagor, or anyone on
behalf of the Mortgagor; (ii) paid by any source other than the Mortgagor or
(iii) 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.


                                       10

<PAGE>




          (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.

          (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 approximately
36.14%; 7.24%; 7.17%; 6.47% and 5.41% of the Mortgage Loans, by Cut-off Date
Principal Balance will be secured by Mortgaged Properties located in California,
Florida, Maryland, New York and Massachusetts, respectively; and approximately
71.81% 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 3.55% of the Mortgage Loans, by the Cut-off Date Principal Balance
are secured by condominiums.



                                       11

<PAGE>



          (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 $261,236.

     Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It is
understood and agreed that the representations and warranties set forth in
Subsections 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 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


                                       15

<PAGE>



particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others.

     Within 90 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 Subsection 3.02 or
3.03 and such breach cannot be cured within 90 days of the earlier of either
discovery by or notice to the Originator of such breach, all of the Mortgage
Loans shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price. 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
Custodial 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 Subsections 3.01, 3.02 or 3.03.


                                       16

     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.

                                   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 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


                                       17

<PAGE>



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 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.

          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


                                       18

<PAGE>



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.

          (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


                                       19

<PAGE>



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 1933 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 1933 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 1933 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 1933 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 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.

                                       21

     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, 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 and the Trustee. 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


                                       22

<PAGE>



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.

referred to in the preceding paragraph, except (i) where the Buyer reports its
securities holdings in its financial statements on the basis of their market
value, and (ii) no current information with respect to the cost of those
securities has been published. If clause (ii) in the preceding sentence applies,

financial statements prepared in accordance with generally accepted accounting
principles and if the investments of such subsidiaries are managed under the
Buyer's direction. However, such securities were not included if the Buyer is a
majority-owned, consolidated subsidiary of another enterprise and the Buyer is
not itself a reporting company under the Securities Exchange Act of 1934, as
amended.

will notify each of the parties to which this certification is made of any
changes in the information and conclusions herein. Until such notice is given,
the Buyer's purchase of the Certificates will constitute a reaffirmation of this
certification as of the date of such purchase. In addition, if the Buyer is a
bank or savings and loan is provided above, the Buyer agrees that it will
furnish to such parties updated annual financial statements promptly after they
become available.

                     AFFIDAVIT OF TRANSFER OF R CERTIFICATES
                           PURSUANT TO SECTION 5.02(d)

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, N.A., 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,


                                       K-1

<PAGE>



trust or estate, and certain cooperatives and, except as may be provided in
Treasury Regulations, persons holding interests in pass-through entities as a
nominee for another Person.)

     5. The Transferee has reviewed the provisions of Section 5.02(d) of the
Agreement and understands the legal consequences of the acquisition of an
Ownership Interest in the 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 K to the Agreement (a "Transferor Certificate") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

     7. The Transferee does not have the intention to impede the assessment or
collection of any tax legally required to be paid with respect to the
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 "noneconomic
residual interest" within the meaning of proposed Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

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